Description

The present invention relates to a dispensing container with a cutter and a solid substance storage container that serves as a refill for the dispensing container with a cutter.

Dispensing containers that are designed to dispense solid substances stored in advance for use are widely used. In addition, dispensing containers with a cutting function that cuts the dispensed solid substances to an appropriate size have been proposed.

For example, Patent Document 1 proposes a dispensing container with a cutter, which is configured such that by rotating a rotating lid with a cutter attached and the container body relative to each other, as the rotating lid rotates, a rising bottom screwed onto the inner circumference of the spiral tube of the container body formed integrally with the rotating lid rises in a rotating state relative to the spiral tube.

Patent No. 4868400

Conventional dispensing containers required a complicated manufacturing process to form a spiral groove on the inner surface.

In addition, in conventional dispensing containers, the rotating lid and the container rotate relative to each other to scrape off the contents, and the engagement between the rotating lid and the container is a fit that involves riding over an annular protrusion, leaving a gap. Therefore, if left exposed to high temperatures, the solid substances melt, and if the container is turned sideways, there is a possibility that the contents will leak out through the gap.

In view of the above circumstances, the present invention aims to provide a dispensing container with a cutter that can prevent the contents from leaking even when the container is placed on its side, while preventing the manufacturing process from becoming complicated.

In order to solve the above problems, in one aspect of the present invention,
a container having a side surface on which a screw projection is formed around an upper end of an outer peripheral surface, and a bottom surface, the container containing a solid substance;
a helical shaft having a helical groove formed on an outer circumferential surface;
a cutter-equipped lid having a top surface provided with a cutter for cutting solid materials below the top surface, the top surface being formed with an outlet through which the solid materials cut by the cutter are scraped out, and a peripheral wall having a screw projection formed on an inner peripheral surface;
A lifting tray arranged to be liftable inside the storage section;
A rotation restricting member that restricts the rotation of the lifting tray relative to the helical shaft,
The lifting tray is formed with a central screw hole through which the helical shaft is inserted and partially screwed, and an insertion hole provided outside the screw hole and through which the rotation restricting member is inserted,
When the rotation restricting member and the helical shaft are rotated relative to each other in a predetermined direction, the lifting plate rises and can cut the upper end of the solid material,
The peripheral wall of the cutter-equipped lid covers a part of the periphery of the upper end of the side surface of the storage part, and the screw protrusions are screw-engaged with each other.
A dispenser with a cutter is provided.

According to one embodiment, in a dispensing container with a cutter, it is possible to prevent the contents from leaking even when the container is placed on its side while preventing the manufacturing process from becoming complicated.

Hereinafter, a description will be given of an embodiment of the present invention with reference to the drawings. In the following drawings, the same components are designated by the same reference numerals, and duplicate explanations may be omitted.

The present invention relates to a dispensing container with a cutter (a dispensing container with a cutting function) and a solid substance storage container that serves as a refill for the dispensing container with a cutter.

The solid substance is a solid cosmetic product or semi-solid cosmetic product, such as a particularly hard hair stick, hair wax, or solid beauty serum (for example, one with a similar hardness to a stick beauty serum), a solid cleansing agent, solid soap, or food such as cheese or butter. In the present invention, the solid substance is set by filling the storage section in advance, filling the storage section by replacing it as a refill (refill container), or filling the storage section with the replaced solid material later.

<Overall Overview>
First, the overall configuration of a dispensing container with a cutter (a dispensing container with a cutting function) 100 according to a first embodiment of the present invention will be described with reference to Figs. 1 and 2.

Figure 1 is an external view of a dispensing container with a cutter 100 according to a first embodiment of the present invention. Figure 2 is a cross-sectional perspective view of the dispensing container with a cutter 100 according to the first embodiment. The cross-sectional view of Figure 2 is a cross-sectional view of the X-plane indicated by the dashed line in Figure 1.

With reference to Figures 1 and 2, the dispensing container with cutter 100 of this embodiment comprises a storage section 1, a spiral shaft 2, a lifting tray 3, a rotation regulating member 4, a lid with cutter 5, and an outer case 6.

In the configuration of the present invention, the solid contents are dispensed by rotating the outer case 6 relative to the cutter-equipped lid 5.

Referring to Figure 1, an outer lid (cap) 8 whose top can be opened and closed may be attached to the dispensing container 100 with a cutter.

Referring to Figure 2, the bottomed storage section 1 is a bottomed tube that is open at the top and stores a solid substance. The storage section 1 has a circular bottom surface 11 and a cylindrical peripheral wall 14. A through hole 12 is formed in the center of the bottom surface 11, and a hanging tube 13 is provided that hangs down from the through hole 12.

The upper end of the peripheral wall 14, which is the side surface, is an upper end thin-walled portion 15 that is thinner on the outside than the other parts, and a screw protrusion 16 is formed on the outer circumferential surface of the upper end thin-walled portion 15.

The helical shaft 2 is a shaft portion that is provided in the center and extends in the vertical direction, and has a helical groove 21 formed on the outer circumferential surface. The upper end of the helical shaft 2 has a cross-shaped groove (cross hole, fitting recess) 22 formed therein.

In the usage state shown in Figure 2, the cross-shaped groove 22 at the upper end of the helical shaft 2 engages with the cross-shaped mating protrusion 54 of the cutter-equipped lid 5, restricting rotation, and the helical shaft 2 rotates together with the cutter-equipped lid 5 when the cutter-equipped lid 5 rotates relative to the outer case 6.

The lifting tray 3 is a lifting base (lifting stage) on which a solid substance is placed. The lifting tray 3 is screwed onto the helical shaft 2 while its rotation is restricted by the rotation restriction member 4. Therefore, the lifting tray 3 can be lifted relative to the helical shaft 2 by the relative rotation of the rotation restriction member 4 and the helical shaft 2.

The rotation control member 4 extends in the vertical direction, surrounds a portion of the helical shaft 2, and is inserted into the lifting plate 3 to rotatably support the helical shaft 2 and regulate the rotation of the lifting plate 3, thereby allowing the lifting plate 3 to be raised and lowered in the vertical direction.

Details of the configuration of the spiral shaft 2, lifting tray 3, and rotation control member 4 will be described later using Figures 3 and 4.

With reference to Figure 1, the lid with cutter 5, which is a lid for scraping solid material, has a top surface 51 and side surfaces 56 (see Figure 7). A cutter 52 (see Figure 7) for cutting solid material is provided on the underside of the top surface 51. An outlet 53, which is a slit hole through which the solid material is scraped out, is formed so as to penetrate the top surface 51. Furthermore, an engagement protrusion 54 is formed in the center of the underside of the top surface 51. A top surface protrusion 55 is formed on the upper surface of the top surface 51, and six outlets 53 are formed in the portion raised by the top surface protrusion 55.

Referring to Figure 2, an engagement protrusion 54 is formed in the center of the underside of the top surface 51. A screw protrusion 57 is formed on the inner peripheral surface of the side surface 56 of the cutter-equipped lid 5.

As shown in Figure 2, the screw protrusion 57 of the cutter-equipped lid 5 threadably engages with the screw protrusion 16 of the storage section 1, thereby restricting rotation of the cutter-equipped lid 5 and the storage section 1.

The outer case 6 in this embodiment is an example of an operating member. The outer case 6 has a bottom surface (bottom plate) 61 and a peripheral wall 64 connected to the bottom surface 61. When the storage unit 1 and the lid with cutter 5 are screw-engaged, a portion of the storage unit 1 and the lid with cutter 5 are housed inside the outer case 6.

A cylindrical protrusion 62 is provided in the center of the bottom surface 61 of the outer case 6. The upper end of the peripheral wall 64 is an upper end thin-walled portion 65 that is thin on the outside, and a threaded protrusion 67 is formed on the outer periphery of the upper end thin-walled portion 65, and an inner peripheral ridge 66 (see Figure 6), which is an undercut protrusion, is provided at the upper end of the inner periphery.

The lower end engagement shaft 48 of the rotation restriction member 4 passes through the through hole 12 in the bottom surface 11 of the storage section 1 and engages with the cylindrical protrusion 62 on the bottom surface 61 of the outer case 6. Details will be described later using Figures 6 and 8.

The outer case 6 is rotatably engaged with the cutter-equipped lid 5.

<Internal structure>
Next, the structures of the helical shaft 2, the lifting tray 3, and the rotation restricting member 4 inside the storage unit 1 according to the first embodiment will be described with reference to Figures 3 and 4. Figure 3 is an exploded perspective view of the helical shaft 2, the rotation restricting member 4, and the lifting tray 3 as viewed from above. Figure 4 is a bottom perspective view of the helical shaft 2, the rotation restricting member 4, and the lifting tray 3 assembled as viewed from below.

Referring to Figure 3, an area in which the helical groove 21 is not formed is provided near the upper end of the helical shaft 2, and a cross-shaped groove 22 is formed on the lower side, inward from the upper end, as a mating recess.

3 shows an example in which the upper end of the helical shaft 2 has a cross-shaped groove 22, but the groove at the upper end of the helical shaft 2 may have another shape as long as it functions as a rotation stopper when engaging with the fitting protrusion 54 and can be formed inside the tube. The shape of the groove at the upper end of the helical shaft 2 may be, for example, a polygon such as a square or pentagon, a pentagram or hexagram, a circle with a line pierced through it, a gear with jagged edges, a knurled shape, a spline shape, etc.

The lifting tray 3 has a screw hole 31, two arcuate holes 34, 35, and linear holes (slits) 36, 37 formed in the tray body 30.

In the lifting tray 3, the central screw hole 31 is defined by the helical inner walls 32, 33, which are partial inner walls on which a helical protrusion is formed. The arched holes 34, 35 are formed continuously from the portion of the central screw hole 31 where the helical inner walls 32, 33 are not present. The linear holes 36, 37 are formed to extend outward from the outer periphery of the arched holes 34, 35.

The rotation regulating member 4 has two curved extension portions 41, 42, two blade members 43, 44, an upper end cylindrical beam 45, lower end connecting portions 46, 47 (see Figure 4), and a lower end engagement shaft 48.

The two curved extensions 41, 42 extend in the vertical direction and are configured as arcs with the same circular cross section so as to surround the outer periphery of the helical shaft 2. In other words, the two curved extensions 41, 42 are configured as vertically split partial cylinders that sandwich a part of the outer periphery of the helical shaft 2 at the same distance from the outer periphery of the helical shaft 2 without contacting it. The upper end cylindrical beam 45 is a member that connects the two curved extensions 41, 42 at the upper end into a cylindrical shape and reinforces them.

The two blade members 43, 44 extend outward from the outer surfaces of the curved extension portions 41, 42 and the outer surface of the upper end cylindrical beam 45.

The lower end engagement shaft 48 extends downward through the center of the arc of the curved extension portions 41, 42. The lower end connecting portions 46, 47 are bow-shaped members that connect the lower ends of the curved extension portions 41, 42 to the lower end engagement shaft 48.

Referring to Figure 4, in the assembled state, the helical shaft 2 is inserted between the curved extension portions 41, 42 of the rotation restricting member 4, and the helical groove 21 of the helical shaft 2 is exposed from the slit-shaped open spaces S1, S2 between the two curved extension portions 41, 42.

The curved extensions 41, 42 and lower end connecting portions 46, 47 of the rotation restriction member 4 are inserted into the arched holes 34, 35 of the lifting tray 3, and the blade members 43, 44 are inserted into the linear holes 36, 37. In the lifting tray 3, the arched holes 34, 35 and the linear holes 36, 37 become insertion holes used to restrict rotation.

In this state, the helical protrusions of the helical inner walls 32, 33 that define the central screw hole 31 engage with the helical groove 21 of the helical shaft 2 exposed from the slit-shaped open spaces S1, S2.

By this engagement, the lifting plate 3 is screwed onto the helical shaft 2 while its rotation is restricted by the rotation restricting member 4, and the lifting plate 3 can be lifted relative to the helical shaft 2 by the relative rotation of the rotation restricting member 4 and the helical shaft 2.

As shown in Figure 4, the lower end engagement shaft 48, which is the lower end engagement part of the rotation restricting member 4, has a polygonal prism shape. The lower end engagement shaft 48, which has a polygonal prism shape, engages with the hollow portion 63 (see Figure 6) of the cylindrical protrusion 62 of the outer case 6 in this manner, and is non-rotatably engaged, restricting the rotation of the rotation restricting member 4 relative to the outer case 6.

Here, the slit-like open spaces S1, S2 extending in the axial direction used for engagement are the remaining portions of the cylindrical space surrounding the helical axis 2 at a distance where the curved extensions 41, 42 are not provided. The angle of the open spaces S1, S2 relative to the center is approximately equal to the angle at which the helical inner walls 32, 33 of the lifting tray 3 are provided.

Therefore, it is preferable that the two open spaces S1 and S2 combined are open at an angle of, for example, about 60° to 300°. Furthermore, taking into consideration the balance between strength, the fixing force of the contents, and the frequency of use of the spiral inner walls 32 and 33, it is even more preferable that the two open spaces S1 and S2 combined are open at an angle of about 120° to 240°.

<Rotating body>
Fig. 5 is a cross-sectional view in which the rotors of the dispensing container with a cutter of Fig. 1 are disassembled. The cross-sectional view of Fig. 5 corresponds to the cross-sectional view of plane Z of Fig. 1.

The mating protrusion 54 of the cutter-equipped lid 5 engages with the cross-shaped groove 22, which is a mating groove at the upper end of the helical shaft 2, thereby restricting the rotation of the helical shaft 2 relative to the cutter-equipped lid 5.

In addition, the cutter-equipped lid 5 and the storage unit 1 are firmly connected to each other so that they cannot rotate, by engaging the screw protrusions (57, 16). In other words, the cutter-equipped lid 5 is attached to the storage unit 1 in such a way that its rotation is restricted.

With this configuration, the rotation of the storage unit 1 and the helical shaft 2 is restricted relative to the cutter-equipped lid 5. Therefore, the storage unit 1, the helical shaft 2, and the cutter-equipped lid 5 shown in FIG. 5 move together as a rotating body A.

On the other hand, as described above, the rotation of the lifting tray 3 is restricted relative to the rotation restricting member 4 by inserting the curved extension portions 41, 42 of the rotation restricting member 4 into the arched holes 34, 35 of the lifting tray 3 and inserting the blade members 43, 44 into the linear holes 36, 37.

Furthermore, in this embodiment, the lower end engagement shaft 48 located at the lower end of the rotation restriction member 4 engages with a cylindrical protrusion 62, which is the bottom engagement portion of the outer case 6, and rotation is restricted.

With this configuration, the rotation restriction member 4 fixes the lifting tray 3 to the outer case 6 side so that it cannot rotate when the outer case 6 and the cutter-equipped lid 5 rotate relative to each other.

In addition, the storage section 1 and the outer case 6 that stores a part of the cutter-equipped lid 5 are rotatably engaged with the cutter-equipped lid 5. Therefore, the lifting tray 3, the rotation restriction member 4, and the outer case 6 move together as a rotating body B.

Therefore, in this embodiment, by rotating the cutter-equipped lid 5 and the outer case 6 relatively in a predetermined direction, the lifting tray 3 can be lifted little by little, and the upper end of the solid material can be cut thinly and uniformly (into a thin plate shape).

In addition, the solid material can be cut out in various shapes by varying the shape of the solid material and the shapes of the cutter 52 and the discharge port 53. For example, by making the discharge port 53 a roughly circular small hole and making the cutter 52 curved downward, the solid material can be cut out in the form of a string (see FIG. 7).

In this way, the lid with cutter 5 of the present invention rotates together with the storage part 1 after the thread engagement. Therefore, no play space for rotation is required between the lid with cutter 5 and the storage part 1, and the inner surface of the lid with cutter 5 and the outer surface of the storage part 1 are sealed by the thread engagement. This engagement configuration makes it possible to prevent leakage of the contents even if the dispensing container with cutter 100 of the present invention is placed on its side and left at a high temperature that would melt part of the solid material of the contents.

Furthermore, in the present invention, the component on which the helical groove for lifting the lifting tray 3 is formed is the central helical shaft 2. The helical shaft has a helical groove formed on its outer circumferential surface, and a helix is formed on its outer surface by being sandwiched between the outer dies, making it easier to manufacture than a configuration in which a helical groove is formed on the inner circumferential surface using a nest.

<Refill Separation>
6 is a cross-sectional view of the dispensing container with a cutter disassembled into a solid substance storage container (refill) α and a housing unit β. The cross section of Fig. 6 is an exploded view of the cross section of plane Z of Fig. 1.

As shown in Figures 6 to 8, the solid substance storage container α is a refill (container) that can be replaced (removed and replaced) together with the solid substance with respect to the outer case 6 and the cutter-equipped lid 5.

The refill solid material storage container α comprises a storage section 1, a helical shaft 2, a lifting tray 3, and a rotation restricting member 4. In addition, on the bottom surface 11 of the storage section 1, a portion extending from the peripheral wall 14 serves as a peripheral lip 17, which is located at a lower position than the other portions.

On the other hand, the housing unit β has a lid 5 with a cutter, an outer case 6, and an outer lid 8. The housing unit β is reused after replacing the refill.

For the housing unit β, the storage section 1 on the main bottle side, the spiral shaft 2, the lifting tray 3, and the rotation restriction member 4 can be made into a refill that can be replaced together with the solid substance. In other words, the empty solid substance storage container α can be replaced with a new refill of the same shape, and the housing unit β can be used repeatedly.

Figure 7 is an explanatory diagram showing how to attach a lid 5 with a cutter to a solid substance storage container α.

In the solid substance storage container α that can be replaced as a refill, the upper surface of the refill, i.e., the upper end of the storage section 1, the upper end of the helical shaft 2, and the upper end of the rotation restricting member 4, can be covered with a film F. This allows the solid substance storage container α that is a refill to be distributed individually.

7, the upper end of the rotation restriction member 4 is the upper end of the upper cylindrical beam 45 and the blade members 43, 44, and is disposed so as to be lower than the upper end of the helical shaft 2. The upper end of the helical shaft 2 is also attached at a position lower than the upper end of the peripheral wall 14 of the storage section 1.

Therefore, when the upper surface of the solid substance storage container α is covered with film F, the upper end of the peripheral wall 14 comes into strongest contact with the film F, and even if it comes into contact with the upper end of the helical shaft 2 due to sagging or the like, the most sagging center surrounds the cross-shaped groove 22 and comes into contact with the flat upper end surface, so the load on the film F is small.

Referring to Figure 7, the lid with cutter 5, which is a lid for scraping solid material, has a top surface 51 and side surfaces 56. A cutter 52 for cutting solid material is provided on the underside of the top surface 51. The top surface 51 also has an outlet 53, which is a slit hole through which the solid material is scraped out, formed therein, penetrating the top surface 51. Furthermore, a fitting protrusion 54, which is a top surface fitting portion, is formed in the center of the underside of the top surface 51.

In this embodiment, six outlets 53 are provided at 60° intervals, and six cutters 52 are provided, the same number as the outlets 53. By providing multiple outlets 53 and cutters 52 in the cutter-equipped lid 5, the contents can be scraped off immediately even if the cutter-equipped lid 5 is rotated only a small angle.

In addition, a screw protrusion 57 is formed on the inner peripheral surface of the side surface 56, which is the peripheral wall of the cutter-equipped lid 5. An outer peripheral protrusion 58 is provided on the outer peripheral surface of the side surface 56 of the cutter-equipped lid 5.

<Installation (1)>
The procedure for attaching the cutter-equipped lid 5 to the solid substance storage container α will be described with reference to FIG.

First, if film F is attached, remove the film F attached to the top end of the solid substance storage container α that will be the refill.

Next, the lid 5 with cutter is placed over the upper end of the storage section 1 while fitting the cross-shaped fitting protrusion 54, which is the top surface fitting portion of the lid 5 with cutter, into the cross-shaped groove 22, which is the upper end fitting portion located at the upper end of the spiral shaft 2.

Then, by rotating the cutter-equipped lid 5 relative to the storage section 1, the screw protrusions (16, 57) are screwed into each other.

In this embodiment, an example has been described in which a cross-shaped fitting protrusion is provided on the cutter-equipped lid 5 side and a fitting groove is provided on the helical shaft side in the engagement between the upper end fitting portion of the helical shaft 2 and the top surface fitting portion of the cutter-equipped lid 5, but the fitting may be reversed. That is, a cross-shaped fitting protrusion may be provided as the upper end fitting portion of the helical shaft, and a shaft tube with a cross groove formed on the inside may be provided as the top surface fitting portion of the cutter-equipped lid 5.

Furthermore, the upper end fitting portion of the helical shaft 2 may be configured as a cylinder having a polygonal prism-shaped hollow portion like the cylindrical protrusion 62, and the top surface fitting portion of the cutter-equipped lid 5 may be configured as a substantially polygonal prism-shaped portion like the lower end engagement shaft 48. Furthermore, this configuration may be reversed, and the upper end fitting portion of the helical shaft 2 may be configured as a substantially polygonal prism-shaped portion like the lower end engagement shaft 48, and the top surface fitting portion of the fitting protrusion 54 may be configured as a cylinder having a polygonal prism-shaped hollow portion like the cylindrical protrusion 62 (see FIG. 8).

Alternatively, the outer shape of the top fitting portion hanging down from the center of the underside of the lid with cutter 5 may be circumferential, with multiple linear protrusions extending up and down on the outer peripheral surface, and the upper end fitting portion of the helical shaft 2 may be cylindrical with multiple vertical grooves on the circumferential inner peripheral surface, thereby restricting rotation. Furthermore, this structure may be such that the fitting portion of the lid with cutter and the upper end of the helical shaft are reversed. Either configuration may be adopted as long as it is possible to restrict the rotation of the helical shaft relative to the lid with cutter 5.

Figure 8 is an explanatory diagram showing how to attach the outer case 6 to a solid substance storage container α having a lid 5 with a cutter attached.

Now, referring to Figure 8, the inside of the cylindrical protrusion 62 formed on the bottom surface 61 of the outer case 6 forms a hollow portion 63 having an approximately polygonal prism shape.

<Installation (2)>
Next, a procedure for attaching the solid substance storage container α having the cutter-equipped lid 5 attached thereto to the outer case 6 will be described with reference to FIG.

When the outer case 6 is inserted into the outer case 6 from the lower end of the storage section 1 in order to attach it, the cylindrical protrusion 62 of the outer case 6 is fitted into the space surrounded by the outer surface of the lower end engagement shaft 48 and the inner circumference of the hanging tube 13 of the storage section 1, while the approximately polygonal outline of the lower end engagement shaft 48 of the rotation restriction member 4 is fitted into the approximately polygonal column-shaped hollow portion 63 of the cylindrical protrusion 62.

This fitting restricts rotation of the rotation restricting member 4 relative to the outer case 6 when the outer case 6 rotates relative to the cutter-equipped lid 5 and the storage section 1.

Furthermore, by pushing the solid material storage container α, which is screw-engaged with the cutter lid, into the outer case 6 so that the engagement between the lower end engagement shaft 48 and the cylindrical projection 62 does not become displaced, the inner peripheral protrusion 66 at the upper end of the outer case 6 climbs over the outer peripheral protrusion 58 on the outer surface of the cutter lid 5. Then, the peripheral lip 17 at the lower end of the storage section 1 reaches a position where it reaches the upper surface of the bottom surface 61 of the outer case 6, and the engagement ends.

Here, the inner peripheral protrusion 66 at the upper end of the outer case 6 is overcome by the outer peripheral protrusion 58 on the outer surface of the lid with cutter, so that the lid with cutter 5 and the outer case 6 are connected to each other so as to be rotatable horizontally without the outer case 6 easily coming off the solid substance storage container α and the lid with cutter 5.

In addition, in this embodiment, an example has been described in which the rotatable engagement parts that can be overcome are both linear protrusions (outer peripheral protrusions 58, inner peripheral protrusions 66), but either one of the overcome parts of the cutter-equipped lid 5 or the outer case 6 may be in the shape of a bump (short cylinder) or an intermittent linear protrusion.

As another configuration, the overpassing member on the refill α side may be replaced with a cutter-equipped lid 5 and provided around the upper end of the storage section 1. In that case, for example, the outer peripheral protrusion 19 and the inner peripheral protrusion 77 in Fig. 9 described later may be arranged around the upper end.

In addition, when the outer lid 8, which is a cap, is attached, the screw projection 67 of the outer case 6 engages with the screw projection 83 of the side wall 82 of the outer lid 8. The outer lid 8 has a top surface 81, and the inner surface of the side wall 82 has a step portion 84 formed by the upper side closer to the top surface 81 being thicker than the lower side (see FIG. 6). When the outer lid 8 is engaged with the outer case 6 to cap it, the step portion 84 of the outer lid 8 presses against the top surface of the cutter-equipped lid 5, thereby preventing the cutter-equipped lid 5 from coming off the outer case 6 even if it receives an impact from the outside due to being dropped, etc.

In this example, a hexagonal outline and inner shape are shown as an example of the engagement between the outer surface of the lower end engagement shaft 48 and the inner surface of the hollow portion 63 of the cylindrical projection 62, but the outline may have any number of sides as long as it is an approximately polygonal shape. It may also be in the shape of a five-pointed star, a six-pointed star, or the like.

Furthermore, the configuration of the lower end engagement shaft 48 and the cylindrical protrusion 62 may be reversed. That is, a lower end engagement tube having a polygonal columnar hollow portion may be provided as the lower end engagement portion at the lower end of the rotation restricting member 4, and a polygonal columnar fitting protrusion having a polygonal outer shape may be provided as the bottom surface engagement portion on the bottom surface 61 of the outer case 6, and the lower end engagement tube of the rotation restricting member 4 may be engaged with the polygonal columnar fitting protrusion of the outer case 6 to restrict rotation.

Alternatively, the outer shape of the lower end engagement shaft 48 may be circular, with multiple linear protrusions extending up and down on the outer peripheral surface, and multiple vertical grooves on the circular inner peripheral surface of the cylindrical protrusion 62 of the outer case 6, or a structure that restricts rotation by using a gear, knurled shape, spline shape, or other shape with jagged edges. Furthermore, even in this structure, the engagement shapes of the lower end engagement portion of the rotation restriction member 4 and the bottom engagement portion of the outer case 6 may be reversed.

Furthermore, the outer shape of the lower end engagement shaft 48 may be a cross-shaped protrusion like the fitting protrusion 54, and the cylindrical protrusion may have a cross groove formed therein like the upper end of the helical shaft 2. Alternatively, the lower end of the lower end engagement part of the rotation restricting member 4 may have a cross groove formed therein like the upper end of the helical shaft 2, and the fitting part on the outer case 6 side may be a cross-shaped protrusion like the fitting protrusion 54. Whichever configuration is adopted, it is sufficient as long as it is possible to restrict rotation of the rotation restricting member 4 relative to the outer case 6.

Second Embodiment
FIG. 9 is a half cross-sectional view of a dispensing container with a cutter 100A according to the second embodiment of the present invention.

In this embodiment, a rotating grip 7 is provided on the underside of the storage unit 1A as an operating member instead of the outer case 6. The internal structures of the storage unit 1A and the lid with cutter 5A are similar to the internal structures of the storage unit 1 and the lid with cutter 5 in the first embodiment.

The rotating grip 7 is a short cylindrical rotating part that is slightly thicker than the storage part 1A. In this embodiment, the rotating grip 7 has a bottom surface (bottom plate) 71 and a peripheral wall that is connected to the bottom surface 71. The peripheral wall is composed of a lower thick peripheral wall 74 and an upper thin peripheral wall 75.

A cylindrical protrusion 72 is provided in the center of the bottom surface 71 of the rotating grip 7. Inside this cylindrical protrusion 72, a polygonal hollow portion 73 similar to that shown in Figure 8 is formed.

A fitting rib 76 is provided at the lower end of the thin peripheral wall 75, where it borders with the thick peripheral wall 74. In addition, an inner peripheral protrusion 77, which serves as an annular undercut protrusion, is provided at the upper end of the inner peripheral surface of the thin peripheral wall 75.

On the other hand, in this embodiment, on the refill side, the outer peripheral surface of the peripheral wall 14A of the storage section 1A is provided with an outer peripheral ridge 19. Instead, the cutter-equipped lid 5A does not have an outer peripheral ridge.

In the assembly of this embodiment, the engagement between the storage section 1A and the rotating grip 7 may occur either after or before the storage section 1A and the cutter-equipped lid 5A are screw-engaged.

In this embodiment, when the storage unit 1A and the rotating grip 7 are engaged, the lower end engagement shaft 48 of the rotation restricting member 4 passes through the through hole 12 in the bottom surface 11 of the storage unit 1A and engages with the hollow portion 73 of the cylindrical protrusion 72 on the bottom surface 71 of the rotating grip 7. Then, by pressing the storage unit 1A into the rotating grip 7, the inner peripheral protrusion 77 of the thick peripheral wall 74 of the rotating grip 7 overcomes the annular protrusion of the peripheral wall of the storage unit and engages. This engagement causes the rotating grip 7 to be rotatably fixed to the storage unit 1A.

In this embodiment, the rotating grip 7 and the storage section 1A are rotated relative to each other to gradually raise the lifting tray 3 and cut the upper end of the solid material into a thin plate.

Although not shown in Fig. 9, the outer shape of the thick peripheral wall 74 of the rotating grip 7 may be formed with a jagged knurling that provides a finger groove with a concave and convex shape to prevent slipping during rotation. Alternatively, as another anti-slip shape during rotation, the cross section of the outer shape of the rotating grip 7 may be made substantially square, triangular, flower-shaped, heart-shaped, etc. to prevent slipping during rotation.

In addition, in this embodiment, an example has been described in which the engagement parts that can be rotated by climbing over are both linear protrusions (outer peripheral protrusion 19, inner peripheral protrusion 77), but either one of the climbing parts of the storage part 1A or the rotating grip 7 may be in the shape of a bump (short cylinder) or an intermittent linear protrusion.

In this embodiment, too, the spiral groove 21 is formed on the outer periphery of the spiral shaft 2, and the storage section 1A and the lid 5A with cutter are tightly attached by screw engagement, so that in the dispensing container 100A with cutter, it is possible to prevent the contents from leaking even when the container is turned sideways while preventing the manufacturing process from becoming complicated.

Figure 10 shows an explanatory diagram of attaching the outer lid 8A to the dispensing container with cutter 100A of the second embodiment. As shown in Figures 9 and 10, the outer lid 8A of this embodiment is provided with four linear ribs 86a, 86b, 86c, and 86d around the top surface 81A of the inner peripheral surface of the side wall 82A. In addition, a spline-shaped projection 85 that projects continuously from the outside to the inside in an annular shape is provided at the lower end of the inner peripheral surface of the side wall 82A of the outer lid 8A.

Also, as shown in Figures 9 and 10, a gear-shaped recess 18 is formed in the upper end of the storage section 1A, which is cut out from above and has a continuous ring shape.

10, when the outer lid 8A, which is a cap, is engaged, the mating rib 76 of the rotating grip 7 engages with a spline-shaped protrusion 85 provided at the inner lower end of the side wall 82A of the outer lid 8A, restricting the rotation of the outer lid 8A and the rotating grip 7. This restricts the outer lid 8A and the rotating grip 7 from rotating relative to each other, even if forces are applied in different directions on the upper and lower sides when the outer lid 8A is engaged.

Furthermore, the linear ribs 86a to 86d on the inside of the outer lid 8A fit into one of the gear-shaped recesses 18, thereby restricting the storage section 1A from rotating relative to the outer lid 8A when the outer lid 8A is capped, and preventing the storage section 1A from coming off the rotating grip 7.

As a result, when the container is capped, the outer lid 8A engages with both the container 1A and the rotating grip 7. Therefore, even if forces are applied in different directions on the top and bottom sides, such as when the dispenser with cutter 100A is packed closely together with other cosmetics in a user's pouch, or when the dispenser is placed in a pocket and rubs against other items, the outer lid 8A and the rotating grip 7 can be prevented from rotating relative to each other. This makes it possible to prevent solid substances from being scraped off arbitrarily within the outer lid 8A.

<Modification>
11 is a bottom view of the rotation restriction member and lifting tray of the present invention and modified examples 1 and 2. In the rotation restriction member and lifting tray shown in FIG. 11, (a) shows the configuration of the first embodiment, (b) shows the configuration of modified example 1, and (c) shows the configuration of modified example 2.

In the above embodiment, the rotation control member 4 has two curved extension portions 41, 42 that extend in the vertical direction and face each other, and the side surface of the helical shaft 2 is covered by the gently arc-shaped inner surfaces of the curved extension portions 41, 42, but the rotation control member of the present invention is not limited to this configuration.

For example, the rotation control member 4B may have three curved extensions spaced 120° apart, with the gently arcuate inner surfaces of the curved extensions covering a portion of the side of the helical shaft 2.

In this case, as shown in Fig. 11(b), the number of blade members 43a, 43b, 43c extending from the curved extension portion is three, the same number as the number of arc-shaped sides, and they are provided 120° apart so that rotation can be evenly restricted. Furthermore, in the lifting tray 3B, the spiral inner wall 32a, 32b, 32c partially surrounding the central screw hole 31B, and the sector holes 34a, 34b, 34c and linear holes 36a, 36b, 36c connected to the part where the spiral inner wall is interrupted are provided in three directions, 120° apart, as shown in Fig. 11(b).

The holes through which the curved extensions are inserted are not limited to the arch-shaped holes 34 and 35 shown in Fig. 11(a), but may be, for example, the fan-shaped holes 34a, 34b, and 34c shown in Fig. 11(b) as long as the outer periphery is arc-shaped. The lower end connecting parts 46a, 46b, and 46c of the rotation restricting member 4B are also fan-shaped to match the shape of the holes.

Similarly, the rotation control member 4C may have four curved extensions spaced 90° apart, with the gently arcuate inner surfaces of the curved extensions covering a portion of the side of the helical shaft 2.

In this case, as shown in Figure 11 (c), the number of blade members 44a, 44b, 44c, 44d extending from the curved extension portion is also four, the same number as the number of arc-shaped sides, and they are provided 90° apart so that rotation can be evenly restricted. In this configuration, the spiral inner wall 33a-33d partially surrounding the central screw hole 31C in the lift tray 3C, the sector holes 35a-35d connecting to the interrupted portion of the spiral inner wall, and the linear holes 37a-37d are provided in four directions, 90° apart. Even in this configuration, the shape of the lower end connecting portions 47a-47d of the rotation restriction member 4C is set to match the shape of the sector holes 35a-35d.

In addition, when the number of curved extension sections in the rotation control member is increased, the spiral shaft still needs to be screwed into the lifting plate. Therefore, when the number of curved extension sections is increased, the width of the arc surface per section is made narrower so that slit-shaped open spaces exposing the spiral grooves are formed between adjacent curved extension sections in the same number as the number of curved extension sections.

In this way, even if the number of curved extension portions of the rotation control member is increased to five, six, etc., by similarly providing the same number of blade members of the rotation control member, spiral inner walls partially surrounding the central screw hole in the lifting tray, arched holes (or fan-shaped holes) connected to the interrupted parts of the spiral inner wall, and linear holes as the number of curved extension portions, the lifting tray can be lifted when the rotation control member and the spiral shaft rotate.

Even in the configuration of the modified example, the lid with cutter and the storage section are screw-engaged, so that, as in the above-described embodiment, in a dispensing container with a cutter, it is possible to prevent the contents from leaking even when the container is turned sideways while preventing the manufacturing process from becoming complicated.

11(b) and (c), the outer surfaces of the blade members (43, 44) can be in contact with the inner walls of the storage section, so that different contents can be filled individually without mixing. Therefore, for example, by filling each space with cosmetics of different colors, cosmetics of different colors can be scraped out for each of the multiple discharge ports 53 during rotation.

Conversely, the rotation restricting member may have only one blade member. Figure 12 shows a bottom view of the rotation restricting member 4D and lifting tray 3D of variant example 3 of the present invention. In this configuration, in addition to the blade member 43D, the curved extension portion 41D may also be one. In this case, the curved extension portion 41D shown by the dotted line in Figure 12 is composed of a partial cylinder that is part of a cylinder that extends in the vertical direction and is split vertically so as to surround part of the outer periphery of the helical shaft without contacting it.

12, in the lifting tray 3D, one arched hole 34D or sector hole, through which one curved extension portion 41D of the rotation restricting member 4D is inserted, is formed continuously from a portion of the central screw hole 31D that does not have the spiral inner wall 32D. Then, one linear hole 36D through which one blade member 43D is inserted is formed so as to extend outward from the outer periphery of the arched hole 34D.

In the assembled state, the helical groove of the helical shaft is exposed from the arc-shaped open space O where the curved extension 41D of the rotation restricting member 4D is not provided. Then, the lower end connecting portion 46D of the lifting tray 3D, which connects the lower end of one of the curved extensions 41D of the rotation restricting member 4D to the lower end engagement shaft 48D, is inserted into the arched hole 34D. As a result, with one blade member 43D inserted into the linear hole 36D, the helical protrusion of the helical inner wall 32D of the central screw hole 31D engages with the helical groove of the helical shaft exposed from the arc-shaped open space O.

In this way, even if the number of curved extension portions 41D of the rotation control member 4D is reduced to one, similarly to the above, by providing the same number of blade members 43D of the rotation control member 4D as the number of curved extension portions 41D, spiral inner walls 32D that partially surround the central screw hole 31D in the lifting tray 3D, arched holes 34D (or fan-shaped holes) that connect to the interrupted portion of the spiral inner wall 32D, and linear holes 36D, the lifting tray 3D can be lifted when the rotation control member 4D and the spiral shaft rotate.

Furthermore, in the above embodiment and modified example, the number of blade members and the number of curved extension portions are equal, but the number of blade members and the number of curved extension portions do not have to be the same. For example, even if there is a single blade member as in Figure 12, by providing two curved extension portions as in Figure 11(a), the effect of stably holding the solid substance inside can be maintained. Alternatively, two or more blade members may extend from one extension member.

Although a preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment described above, and various modifications and variations are possible within the scope of the gist of the present invention as described in the claims.
