Description

The present invention relates to a container with a lid that is suitable for storing contents such as cosmetics and medicines.

A container with a lid, as described in, for example, Patent Document 1 below, has been known in the past. This container with a lid is a so-called dispensing container, and includes a container body that contains the contents, and a lid body that is removably attached to the container body.

JP 2003-102543 A

This type of container with lid is usually attached by pushing the lid into the sleeve of the container body with the fingers, so that the lid fits over the container body. This makes it difficult to give the container with lid itself a luxurious feel, and there is still room for improvement.

Furthermore, in this type of lidded container, for example, when a magnet is used to engage the lid with the container body, when the lid is detached from the container body and then is attached to the container body, the attractive force of the magnet may cause the lid to move forcefully toward the container body, which may collide with the container body and produce a loud noise.Furthermore, some users may feel that the lid feels unpleasant when it collides with the container body, detracting from the luxurious feel.

The present invention was made in consideration of the above-mentioned circumstances, and aims to provide a lidded container with a luxurious feel by allowing the lid to move (lower) slowly under its own weight when attaching the lid to the container body from above, without the need to push the lid down with fingers.

The container with lid of the present invention, which has been developed to achieve the above object, comprises: a container body having a storage tube for storing contents;
A tubular lid body with a top that is detachably attached to the container body;
an engaging member provided on either the container body or the lid;
a mating member provided on the other of the container body and the lid body, the mating member engaging with the mating member to detachably lock the container body and the lid body,
the container body has a decorative cylinder disposed around the storage cylinder, with the outer peripheral wall of the storage cylinder facing the inner peripheral wall of the lid body, and the lid body being detachably attached to the container body;
The gap formed between the inner peripheral wall of the lid body and the outer peripheral wall of the decorative barrel is 0.025 to 0.1 mm at its narrowest point, and
The lid body is characterized in that the inner wall has an angle of more than 0° and not more than 0.1° from the zenith to the open end, and has a slope that causes the internal space formed by the inner wall to expand toward the open end of the lid body .

In addition, in the container with lid of the present invention,
(1) The engaging member is a first magnet, and the engaged member is an attracting member that faces the first magnet in the container axial direction and is attracted to the first magnet.
(2 ) The attraction member is a magnet.
is preferred.

According to the lidded container of the present invention, when the lid is attached to the container body, the gap between the inner peripheral wall of the lid and the outer peripheral wall of the decorative tube of the container body is configured to be within the range of 0.025 to 0.1 mm at its narrowest point, which makes it difficult for air in the gap to escape and suppresses the movement (descent) of the lid along the decorative tube of the container body. Therefore, according to the present invention, it becomes possible to slowly move (descent) the lid along the container body (decorative tube) by its own weight, giving the lidded container a luxurious feel.

In addition, according to the container with lid of the present invention, even if the engaging member provided on either the lid or the container body is made of a first magnet and the engaged member provided on the other of the lid or the container body is made of an attraction member, the moving speed of the lid toward the container body when the attraction member is attracted to the first magnet can be reduced, and the lid can be slowly attached to the container body. Therefore, the impact generated when the lid contacts the container body can be reduced, and the sound generated at that time can be suppressed. In addition, according to the present invention, when the lid is attached to the container body, the lid is slowly and smoothly attached while being aligned by the attraction force of the magnet, which further improves the sense of luxury and the operability.

In addition, according to the lidded container of the present invention, the inner peripheral wall of the lid is inclined from the apex toward the open end at an angle of more than 0° and not more than 0.1°, and the internal space formed by the inner peripheral wall is expanded toward the open end of the lid, which allows the lid to be smoothly released from the mold during molding of the lid. Furthermore, by setting the inclination at 0.1° or less, the gap between the outer peripheral wall of the decorative tube of the container body and the inner peripheral wall of the lid can be made almost constant in the axial direction of the container, and the effect of reducing the moving speed when the lid is attached to the container body can be effectively exerted.

FIG. 1 shows one embodiment of a lidded container of the present invention, where (a) is a plan view showing the lid removed (the dotted line indicates the lid), and (b) is a cross-sectional view taken along the line A-A. 2 is an enlarged cross-sectional view showing a fitting position between the lid and the container body of the lidded container of FIG. 1. 2 is a cross-sectional view of the lidded container of FIG. 1 taken along the line B-B.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Fig. 1 shows a container with lid 10 according to one embodiment of the present invention, where Fig. 1(a) is a plan view showing the container with lid removed, and Fig. 1(b) is a cross-sectional view taken along the line A-A. Fig. 2 is a cross-sectional view showing an enlarged view of the fitting position between the lid and the container body of the container with lid 10 shown in Fig. 1, and Fig. 3 is a cross-sectional view taken along the line B-B of the container with lid 10 shown in Fig. 1.

In this embodiment, the container with lid 10 is a so-called dispensing container, which contains rod-shaped contents such as cosmetics (lipstick, lip balm, stick eye shadow, etc.), medicine, or glue in a manner that allows them to be dispensed and retracted. However, the container with lid 10 is not limited to a dispensing container, and may be, for example, a jar container or a compact container, and when the container with lid 10 is a jar container or the like, the contents are not limited to a solid form, and various forms such as liquid, viscous, or powdery can be used.

1 to 3, the container with lid 10 comprises a container body 20 and a lid body 40. The container body 20 accommodates contents therein, and the lid body 40 is in the shape of a cylinder with a top so as to cover the upper part of the container body 20 and is detachably attached to the container body 20.
Here, the central axes of the container body 20 and the lid body 40 are located on a common axis. Hereinafter, the common axis is referred to as the container axis O, the lid body side along the container axis O direction is referred to as the upper side (one side), and the container body side along the container axis O direction is referred to as the lower side (the other side). The direction perpendicular to the container axis O is referred to as the radial direction, and the direction going around the container axis O is referred to as the circumferential direction.

The container body 20 includes a main body tube 21, a storage tube 22, a decorative tube 23, a sliding ring 24, a middle plate 25, and a first magnet 26 as an engagement member. The main body tube 21, the storage tube 22, the decorative tube 23, the sliding ring 24, and the middle plate 25 can each be manufactured using a synthetic resin material, but the material is not particularly limited. In addition, in this embodiment, as described below, the container body 20 is shown as an example in which the main body tube 21 is rectangular and the storage tube 22 and the decorative tube 23 are circular, but the shape of the container can be changed appropriately based on the type of content, the design of the container, the purpose, etc., and is not limited to the shape shown in the figure.

The main body tube 21 is a bottomed tube, and includes a first outer tube 27 and a first inner tube 28. The first outer tube 27 is a bottomed tube, the first inner tube 28 is a tube that opens on both sides in the direction of the container axis O, and the first inner tube 28 is disposed within the first outer tube 27. Rotation of the first inner tube 28 relative to the first outer tube 27 is restricted, for example, by the two engaging with each other. The first inner tube 28 rotates in conjunction with the circumferential rotation of the first outer tube 27, and vertical movement of the first inner tube 28 relative to the first outer tube 27 is restricted, for example, by the two engaging with each other.

The lower end of the storage tube 22 is disposed within the main body tube 21 and extends upward from the main body tube 21. The upper end of the storage tube 22 is located above the main body tube 21, and the rotation of the storage tube 22 relative to the main body tube 21 is regulated, for example, by the two engaging with each other through an undercut fit. The storage tube 22 rotates in conjunction with the circumferential rotation of the main body tube 21, and the up and down movement of the storage tube 22 relative to the main body tube 21 is regulated, for example, by the two engaging with each other through an undercut fit.

The decorative tube 23 is made of a double cylinder and is arranged to surround the outside of the storage tube 22, with its lower end sandwiched between the lower end of the storage tube 22 and the main body tube 21. Rotation of the decorative tube 23 relative to the main body tube 21 and the storage tube 22 is restricted, for example, by the formation of locking portions that face and abut in the vertical direction. In addition, the decorative tube 23 can rotate in the circumferential direction relative to the main body tube 21 and the storage tube 22.

The sliding ring 24 regulates the relative rattle between the storage tube 22 and the decorative tube 23. The sliding ring 24 is disposed between the lower end of the storage tube 22 and the lower end of the decorative tube 23, and the rotation of the sliding ring 24 relative to the storage tube 22 is regulated, for example, by the two engaging with each other. On the other hand, the rotation of the sliding ring 24 relative to the decorative tube 23 is not regulated. When the main tube 21 and the storage tube 22 rotate, the sliding ring 24 rotates while sliding on the inner peripheral wall of the decorative tube 23.

The inner plate 25 is housed in the storage tube 22 and supports the contents from below. As the storage tube 22 and the decorative tube 23 rotate relative to each other, the inner plate 25 moves up and down inside the storage tube 22. This movement can be achieved by a structure used in known dispensing containers (for example, a structure including a protrusion, a vertical groove, or a spiral groove, or a structure including a screw shaft and in which the inner plate is screwed onto the screw shaft, etc.).

In the container body 20 of this embodiment, a first circumferential groove 29 is provided at the upper end of the first outer tube 27 of the main body tube 21. The first circumferential groove 29 opens radially inward and also opens upward. Furthermore, a first flange 30 is provided at the upper end of the first inner tube 28 of the main body tube 21. The first flange 30 is located below the upper end surface of the first inner tube 28, is disposed within the first circumferential groove 29, and its lower surface is supported by the lower surface of the first circumferential groove 29. Furthermore, the upper surface of the first flange 30 is at the same height as the upper end surface of the first outer tube 27.

The container body 20 is provided with an annular receiving surface 31 and an annular protrusion 32. The receiving surface 31 is located opposite the lower end surface 40b of the lid body 40, and may be in contact with the lower end surface 40b or may be separated from the lower end surface 40b. The receiving surface 31 is formed by the upper end surface of the first outer tube 27 and the upper end surface of the first flange 30.

The protrusion 32 is provided radially inward from the receiving surface 31. The protrusion 32 protrudes above the receiving surface 31 and is formed by a portion of the first inner tube 28 that is located above the first flange 30.

As shown in FIG. 1(a), in a plan view of the container body 20, the outer peripheral surface of the protrusion 32 is rectangular (hereinafter referred to as a first rectangular shape 33) and has four first corners 34 and four first sides 35. In addition, in a plan view, the inner peripheral surface of the storage tube 22 is circular.

The first magnet 26 is disposed at a position corresponding to the first corner 34. Here, the position corresponding to the first corner 34 is a position on a virtual straight line (hereinafter referred to as the first straight line L1) that passes through the container axis O and the first corner 34 in the plan view, and the first magnet 26 is located on the first straight line L1.

As shown in FIG. 3, the first magnet 26 is fitted into a first recess 36 provided in the protrusion 32 of the first inner cylinder 28. In this embodiment, the upper end of the first magnet 26 is disposed within the protrusion 32. In other words, a portion of the protrusion 32 is formed by the first magnet 26.

As shown in FIG. 1, the lid 40 is formed in a cylindrical shape with a top so as to cover the entire upper half of the cosmetic tube 23, and is detachably attached to the container body 20. The lid 40 is made of a double cylindrical shape of a second outer tube 41 and a second inner tube 42, and is provided with a second magnet 43 (attraction member) as an engaged member. The second outer tube 41 and the second inner tube 42 are cylindrical with a top. The lid 40 can be manufactured using a material such as a synthetic resin, but the material is not particularly limited, and it may be manufactured using the same material as the container body 20 or a different material. In this embodiment, the lid 40 is shown as an example having a rectangular shape in a plan view as described later, but the shape of the lid 40 can be changed appropriately based on the type of content, the design of the container, the purpose, etc., and is not limited to the shape shown in the figure.

The second inner cylinder 42 is disposed within the second outer cylinder 41. Rotation of the second inner cylinder 42 relative to the second outer cylinder 41 is restricted. The second inner cylinder 42 rotates in conjunction with the circumferential rotation of the second outer cylinder 41. Up-down movement of the second inner cylinder 42 relative to the second outer cylinder 41 is restricted.
Note that a known configuration may be appropriately adopted as a configuration for restricting the rotation of the second inner cylinder 42 relative to the second outer cylinder 41. Also, a known configuration may be appropriately adopted as a configuration for restricting the up and down movement of the second inner cylinder 42 relative to the second outer cylinder 41.

As shown in FIG. 2, the cover 40 has a second circumferential groove 44 at the lower end of the second outer tube 41. The second circumferential groove 44 opens radially inward and downward. Furthermore, an expanded diameter portion 45 and a second flange 46 are provided at the lower end of the second inner tube 42 of the cover 40. The expanded diameter portion 45 is located at the lowest end of the second inner tube 42 and has a larger diameter than the portion of the second inner tube 42 located above the expanded diameter portion 45. The second flange 46 is located at the lower end of the expanded diameter portion 45 and is disposed within the second circumferential groove 44. The lower surface of the second flange 46 is flush with the lower end surface of the expanded diameter portion 45 and the lower end surface of the second outer tube 41.

In the lid body 40, the inner diameter of the lower end 40a of the lid body 40 is larger than the inner diameter of the portion of the lid body 40 located above the lower end. The lower end 40a of the lid body 40 is formed by the lower end of the second outer tube 41 and the lower end (expanded diameter portion 45) of the second inner tube 42. The inner peripheral surface of the lower end 40a of the lid body 40 is formed by the expanded diameter portion 45. The lower end surface 40b of the lid body 40 is formed by the lower end surface of the expanded diameter portion 45, the lower surface of the second flange 46, and the lower end surface of the second outer tube 41.

The lower end 40a of the lid 40 is positioned so as to cover the protrusion 32 of the container body 20 from the radial outside. The inner circumferential surface of the lower end 40a of the lid 40 is connected via a step 50 to the inner circumferential surface of a portion of the lid 40 that is located above the lower end 40a. The step 50 and the upper end surface of the protrusion 32 face each other in the direction of the container axis O. The step 50 and the upper end surface of the protrusion 32 may be in contact or may be separated.

As shown in FIG. 1(a), the inner peripheral surface of the lower end portion 40a of the lid body 40 is rectangular (hereinafter referred to as the second rectangular shape 47) in a plan view. The second rectangular shape 47 is similar to the first rectangular shape 33 and has a larger diameter than the first rectangular shape 33. The second rectangular shape 47 also has four second corners 48 and four second sides 49.

3, the second magnet 43 faces the first magnet 26 in the direction of the container axis O. The second magnet 43 is disposed above a step 50. The second magnet 43 functions as an attraction member that is attracted to the first magnet 26. However, unlike a simple magnetic body (e.g., some metals such as iron), the second magnet 43 and the first magnet 26 are attracted to each other.
In this embodiment, the second magnet 43 is disposed at a position corresponding to the second corner 48. Here, the position corresponding to the second corner 48 is a position on a virtual straight line (hereinafter referred to as a second straight line L2) that passes through the container axis O and the second corner 48 in the plan view of Fig. 1(a), and the second magnet 43 is located on the second straight line L2.

As shown in FIG. 3, the second magnet 43 is attached to the second inner cylinder 42. The second inner cylinder 42 has a second recess 51 that is recessed downward, and the second magnet 43 is fitted into the second recess 51.

In this embodiment, the container body 20 is provided with a first magnet 26 as an engaging member, the lid body 40 is provided with a second magnet 43 as an engaged member, and the lid body 40 is moved toward the container body 20 while being aligned by mutual attraction between the first magnet 26 and the second magnet 43, thereby attaching the lid body 40 to the container body 20. However, the present invention is not limited to this, and the engaging member and the engaged member may have any structure as long as they can detachably engage the container body 20 and the lid body 40, for example, an undercut fitting or the like can be used.

In the lidded container 10 having the container body 20 and the lid body 40 configured as described above, when the lid body 40 is detached from the container body 20 and fitted into the decorative tube 23 of the container body 20 so as to cover it from above, the lid body 40 slowly descends along the decorative tube 23 due to its own weight, and then the second magnet 43 of the lid body 40 is attracted to the first magnet 26 of the container body 20, and the lid body 40 moves relative to the container body 20 while aligning itself, allowing the lid body 40 to be easily attached to the correct position on the container body 20 without the user having to perform any operations.

In this embodiment of the lidded container 10, the second inner tube 42 of the lid body 40 has an inner diameter that is 0.05 to 0.2 mm larger than the outer diameter of the decorative tube 23 of the container body 20, and when the lid body 40 is attached to the container body 20 as shown enlarged in FIG. 3, the gap D formed between the inner wall surface of the second inner tube 42 and the outer wall surface of the decorative tube 23 is configured to be 0.025 to 0.1 mm at its narrowest point. Note that the gap D may be formed so that it falls within the above range over the entire length in the direction of the container axis O, or may be partially larger than the above range.

By setting the gap D within the above range, when the lid body 40 is fitted to cover the decorative tube 23 of the container body 20 from above, the air in the gap D is less likely to escape (the air is released slowly), and the movement of the lid body 40 along the decorative tube 23 is suppressed. As a result, the lid body 40 moves (descends) slowly along the decorative tube 23 due to the effect of the gap D, and then, due to the attraction between the second magnet 43 of the lid body 40 and the first magnet 26 of the container body 20, the moving speed when moving relative to the container body 20 is reduced, and the lid body 40 can be slowly attached to the container body 20. As a result, the lid body 40 can be slowly lowered by its own weight without the user having to push the lid body 40, etc., improving the operability of the lid-equipped container 10 and ensuring a luxurious feel, and also mitigating the impact generated when the lid body 40 comes into contact with the container body 20, and reducing the generated sound.

If the gap D is less than 0.025 mm, the air resistance becomes too large and the lid body 40 cannot be smoothly attached to the container body 20. On the other hand, if the gap D is more than 0.1 mm, the moving speed of the lid body 40 toward the container body 20 cannot be sufficiently reduced.

In addition, it is preferable that the inner peripheral wall of the second inner cylinder 42 of the lid body 40 is inclined radially outward at an angle of more than 0° and not more than 0.1° from the apex toward the lower end 40a. This allows the internal space of the lid body 40 formed by the inner peripheral wall of the second inner cylinder 42 to expand toward the open end, and allows the lid body 40 to be smoothly released from a mold when the lid body 40 is molded by a molding method such as injection molding.
Furthermore, by setting the inclination to 0.1° or less, the gap between the outer wall of the decorative tube 23 of the container body 20 and the inner wall of the second inner tube 42 of the lid body 40 can be made approximately constant in the direction of the container axis O, thereby effectively achieving the effect of reducing the moving speed when the lid body 40 is attached to the container body 20 .

In addition, in this embodiment, the first magnet 26 and the second magnet 43 are attracted to each other (when the second magnet 43 as an attraction member is attracted to the first magnet 26, the first magnet 26 is also attracted to the second magnet 43), so the first magnet 26 and the second magnet 43 are attracted to each other more strongly than when, for example, a magnetic material that is simply attracted to the first magnet 26 is used as the attraction member, and the lid body 40 is firmly attached to the container body 20. In addition, the speed at which the lid body 40 moves relative to the container body 20 can be easily increased, but as described above, the effect of reducing the movement speed of the lid body 40 is significantly achieved by setting the gap D to 0.025 to 0.1 mm.

In addition, instead of the second magnet 43, a magnetic material such as iron may be used as the suction member attracted to the first magnet 26. In this case, it is possible to appropriately adopt a configuration in which the first magnet 26 is provided on either the container body 20 or the lid body 40, and the magnetic material as the suction member is provided on the other of the container body 20 and the lid body 40.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. Furthermore, the components in the above-described embodiment can be replaced with well-known components as appropriate.
