JP7525244B2 - Storage container containing impregnated body and refilling tool - Google Patents

Description

The present invention relates to a container that contains an impregnated body that is impregnated with a liquid, and a refilling tool for refilling the liquid into the impregnated body.

For example, a cosmetic container (container for housing an item to be coated) that houses an impregnated body (such as a sponge) that is impregnated with a viscous content liquid such as foundation is known (see, for example, Patent Document 1).
In such a storage container, when the remaining amount of the content liquid impregnated in the impregnated body becomes low through use, it is possible to continue using the container by injecting new content liquid into the impregnated body from the outside.
In the prior art described in Patent Document 1, when a plug blocking an injection hole provided at the bottom of the container body is removed and the material to be coated is injected through the injection hole into a recess in the impregnated body inside the container body, the material to be coated flows from the recess through a groove-like slit formed in the impregnated body, thereby improving the impregnation of the impregnated body.

JP 2018-186947 A

However, in the prior art described in Patent Document 1, slits for improving impregnation must be formed in a complex shape on the surface or inside the impregnated body, or the impregnated body must be composed of multiple components, which makes the manufacturing process for the impregnated body more complicated and makes it difficult to reduce manufacturing costs.

The present invention aims to solve the problems in the conventional technology described above by creating a storage container and a refilling tool for the container that contains an impregnated body that improves impregnation with a simple structure.

Among the means for solving the above problems, the first main means of the present invention is:
A storage container having an impregnated body formed by laminating a plurality of impregnated layers and an inner container having a refill hole for refilling the content liquid,
The refill hole is characterized in that it is formed by a through hole that penetrates radially through the side wall of the inner container and is arranged opposite to a gap formed between any of the impregnated layers.
In the main aspect of the present invention, the refill hole faces the gap formed between the impregnated layers of the impregnated body formed by laminating a plurality of impregnated layers, so that the content liquid supplied through the refill hole can be reliably poured into the gap, thereby improving the impregnation of the content liquid into the impregnated body.

Another aspect of the present invention is the first main aspect of the present invention, further comprising the step of forming the impregnated body by stacking an upper impregnated layer on a lower impregnated layer.
In the above-mentioned means, the content liquid can be poured into the center of the impregnated body having a two-layer structure, so that the impregnation of the content liquid into the impregnated body can be improved.

Another aspect of the present invention is to add to the above-mentioned aspect that annular slits are formed on at least one of the opposing surfaces of the lower impregnated layer and the upper impregnated layer, the slits being concentrically arranged at a predetermined interval in the radial direction.
In the above-mentioned means, the content liquid is poured into each annular slit, so that the content liquid can be impregnated relatively evenly over the entire area of the impregnated body.

Another means of the present invention is any of the above means, further comprising the addition of a means in which the inner container is formed with an inner container body having a first through hole formed therein, an inner lid closing the open end of the inner container body, and a bottom lid rotatably attached to the lower end of the inner container body and formed with a second through hole, and the bottom lid is rotated relative to the inner container body so that the first through hole and the second through hole overlap each other to form a refill hole.
With the above-mentioned means, the refill hole can be formed only when the bottom lid is rotated relative to the inner container body, so that leakage of the content liquid can be prevented.

Among the means for solving the above problems, the second main means of the present invention is:
A refilling tool for refilling the liquid contained in the impregnated body contained in any one of the above-mentioned storage containers,
It is characterized by having a refilling device body with a nozzle portion that is erected via a neck portion from a body portion filled with the liquid content, and a nozzle portion that is connected to the tip of the nozzle portion and can be inserted into a refilling hole provided in a storage container, and an outlet hole for injecting the liquid content is formed in the nozzle portion.

In the second main aspect of the present invention, the nozzle portion can be inserted into a refill hole provided in the storage container, so that the liquid content can be supplied to the impregnated body provided in the storage container, making it easy to refill the liquid content.

Another aspect of the present invention is the second main aspect of the present invention, wherein a plurality of injection holes are formed between the base end and the tip end of the nozzle portion at the same intervals as the plurality of annular slits formed in the lower impregnated layer and the upper impregnated layer that constitute the impregnated body.
With the above-mentioned means, the spacing between the multiple pouring holes formed on the outer peripheral surface of the nozzle portion can be made to match the spacing between the multiple annular slits formed in the lower impregnated layer and upper impregnated layer of the impregnated body, so that the content liquid poured out from each pouring hole can directly enter each annular slit.

Another aspect of the present invention is any one of the above aspects, further comprising the addition that the hole diameters of the multiple injection holes are formed so as to gradually increase from the base end of the nozzle portion toward the tip end.
With the above-mentioned means, it is possible to more uniformly pour the content liquid into each annular slit, thereby improving the impregnation of the content liquid into the impregnated body.

Another aspect of the present invention is any one of the above aspects, further comprising the addition of an annular flange that protrudes radially outwardly from the outer circumferential surface of the neck.
With the above-mentioned means, when the nozzle portion is inserted into the refilling hole, the annular flange seals the gap between the filler and the inner container, thereby preventing the contents from flowing back and leaking out of the refilling hole.

The present invention provides a storage container and a refilling tool for the container that contains an impregnated body that improves impregnation, with a simple structure of stacking two sheets of an upper impregnated layer and a lower impregnated layer.

First, the configuration of the container will be described.
The storage container 1 of the present invention is a container capable of storing therein an impregnated body impregnated with a viscous content liquid such as foundation, and a cosmetic tool (such as a puff or a brush).
As shown in Figures 1(a) and (b), the storage container 1 is composed of an outer container body 10 and an outer lid 20 that constitute the outer container A, an inner container body 30 and an inner lid 35 that constitute the inner container B, a bottom lid 40 that constitutes the bottom of the outer container A and the inner container B, and an impregnated body 50 that is impregnated with the content liquid, and each component except for the impregnated body 50 is formed by injection molding of a synthetic resin material.

First, the outer container body 10 and the outer lid 20 that constitute the outer container A will be described.
As shown in Fig. 1 and Fig. 2, the outer container body 10 is a member formed in a short cylinder shape with a large circular opening 11 at the bottom. A hook recess 12 is formed at one front side (left side in Fig. 2) of the outer container body 10, and a push button 60 with a pressing piece 61 on the upper surface is provided inside the hook recess 12. The push button 60 has a biasing member (not shown) that applies a biasing force toward the outside in the radial direction and is provided so as to be movable forward and backward along the radial direction (also the front-rear direction). In addition, a locking claw 12a that protrudes toward the outside in the radial direction is protruded from the hook recess 12. In addition, a hinge recess 13 is formed on the other rear side (right side in Fig. 2) of the outer container body 10. Bearing parts (not shown) are provided on both inner surfaces facing each other in the width direction of the hinge recess 13.

At multiple locations (four locations in this embodiment) on the inner wall 14 that forms the opening 11 of the outer container body 10, undercut locking protrusions 15 are formed that protrude radially inward toward the container axis O1. A hinge insertion portion 16, which will be described later, is formed on one widthwise surface of the inner wall 14 (the upper surface in FIG. 2), and a concave rib insertion portion 17 is formed on the other opposing surface (the lower surface in FIG. 2). The hinge insertion portion 16 is formed by cutting out a large concave portion of the upper surface of the inner wall 14, and the rib insertion portion 17 is formed as a vertical groove that extends from the upper surface to the bottom of the inner wall 14. The hinge insertion portion 16 is formed at a position that is shifted 90 degrees circumferentially from the hinge recess 13.

As shown in Fig. 1(a), the outer cover 20 is a cylindrical member with a top and a peripheral wall 22 suspended from the outer edge of a top plate 21, and a mirror M is fixed to the inner surface of the top plate 21. A locking wall 23 having a locking claw 23a at its lower end is suspended from the front side (left side in Fig. 1(a)) of the top plate 21, and an arm portion 25 having an axis member 24 extending in the width direction is integrally formed with the peripheral wall 22 on the rear side (right side in Fig. 1(a)).
A hinge H is formed by inserting the arm portion 25 of the outer lid 20 into the hinge recess 13 of the outer container body 10 and pivoting both ends of the shaft member 24 to bearing portions (not shown) provided on both inner surfaces of the hinge recess 13. The outer lid 20 is pivotally supported by the hinge H to the outer container body 10 so as to be freely rotatable, and is configured to be freely opened and closed.

When the outer lid 20 is closed, the engaging claw 23a on the outer lid 20 engages and locks with the engaging claw 12a on the outer container body 10, setting the storage container 1 in a closed state. When the push button 60 is pressed radially inward from this state, the pressing piece 61 abuts against the lower end of the locking wall 23 and pushes the engaging claw 23a upward, causing the engaging claw 12a to disengage from the engaging claw 23a and release the lock, allowing the storage container 1 to be set in an open state in which the outer lid 20 is open.

Next, the inner container body 30, the inner lid 35 and the bottom lid 40 that constitute the inner container B will be described.
As shown in Figures 1(a)(b), 3(a)(b) or 4(a)(b), the inner container body 30 is formed with a substantially cylindrical side wall portion 31, the upper end of which is provided with an inner flange 32 that protrudes radially inward in an annular shape and holds an upper impregnated layer 51 (described later), an annular groove 33 for sealing formed on the outside thereof, and a first engagement portion 34 that is formed further outside and engages with an inner lid 35 (see Figure 1(b)).
A second engagement portion 31a for engaging with the bottom lid 40 is formed at the lower end of the side wall portion 31. Furthermore, as shown in Figures 3(a) and 3(b) and 4(a) and 4(b), a first through hole 31A is formed radially through the side wall portion 31 at a position that faces the front of the inner-container body 30, and a restricting recess 31B is formed in a position adjacent to the upper side thereof, which is recessed and has a predetermined length in the circumferential direction.

1(a) and 1(b), the inner lid 35 is a member including a peripheral wall 36 formed in a short cylindrical shape and a disk-shaped top wall portion 37 formed on the inner surface of the peripheral wall 36 at the middle in the height direction. The space formed in a concave cross section by the top wall portion 37 and the peripheral wall 36 protruding upward from the top wall portion 37 is a first storage portion Q1 for storing a cosmetic tool P such as a puff. An engagement claw 36a is formed at the lower end of the peripheral wall 36, protruding radially inward and engaging with the first engagement portion 34 on the inner container body 30 side when the lid is closed. A cylindrical seal tube portion 38 protruding downward is formed on the inner side of the peripheral wall 36 and on the inner surface of the top wall portion 37.
The inner container body 30 and the inner lid 35 are integrally connected via a hinge 39 made of a thin wall, and the inner lid 35 is provided so as to be openable and closable with respect to the inner container body 30 by rotating via the hinge 39. When the inner lid 35 is closed, the sealing cylinder 38 on the inner lid 35 side fits into the annular groove 33 on the inner container body 30 side to provide a seal, and the engagement claw 36a on the inner lid 35 side engages with the first engagement portion 34 on the inner container body 30 side to maintain the closed state.

Next, the bottom cover 40 constituting a part of the inner container B will be described.
As shown in Figures 1(a) and 1(b), the bottom cover 40 is a bottomed cylindrical member in which a short cylindrical side wall 42 is integrally provided on the outer edge of a disk-shaped bottom wall 41. As shown in Figures 3(a) and 3(b), the side wall 42 has a plurality of locations (four locations in Figures 3(a) and 3(b)) on its outer peripheral surface that correspond to the locking protrusions 15 formed on the outer container body 10, and the locking recesses 43 are formed thereon that can engage with the locking protrusions 15. In addition, the side wall 42 has a predetermined length in the circumferential direction and a restricting protrusion 44 that protrudes upward (see Figures 3(a) and 4(a)) on its outer peripheral surface and on the front surface of the bottom cover 40. A protruding rib 45 extending linearly along the height direction is protruded from this restricting protrusion 44 at a position on the front side of the bottom cover 40, and a second through hole 46 is bored at a position shifted in the circumferential direction from this protruding rib 45 (a position on the left side of the protruding rib 45 in Figures 3(a) and 3(b)) and passes radially through the side wall 42. Furthermore, an engaged portion 47 is formed at the lower end on the inner surface side of the side wall 42 (see Figures 1(a) and 1(b)).

Next, the impregnated body 50 will be described.
The impregnated body 50 is made of a porous soft material such as a sponge. The impregnated body 50 is configured by laminating two sheets, an upper impregnated layer 51 and a lower impregnated layer 52, which are formed in the same shape of a substantially circular plate with a predetermined thickness dimension, in the height direction, and a gap S is provided between the upper impregnated layer 51 and the lower impregnated layer 52, which face each other.
The upper impregnated layer 51 and the lower impregnated layer 52 may be formed by stacking two impregnated layers formed separately as described above, or by cutting one impregnated layer horizontally in the middle in the thickness direction, or by folding one impregnated layer in two.

Next, assembly of the container will be described.
First, the bottom lid 40 is attached to the lower end of the inner container body 30 to form the inner container B. At this time, a second storage section Q2 for storing the impregnated body 50 is formed in the space where the bottom wall 41 of the bottom lid 40 and the inner lid 35 of the inner container body 30 face each other in the height direction, and the impregnated body 50 is stored in the second storage section Q2 during the assembly process.
Specifically, the second engaging portion 31a formed on the side wall portion 31 of the inner container body 30 is engaged with the engaged portion 47 formed on the side wall 42 of the bottom lid 40, thereby assembling the two. At this time, the restricting protrusion 44 on the bottom lid 40 side is disposed within the restricting recess 31B on the inner container body 30 side. In the assembled state, the bottom lid 40 and the inner container body 30 can rotate relatively in the circumferential direction within a range where both circumferential ends of the restricting protrusion 44 and the restricting recess 31B abut against each other.

3(a) and 3(b), when the bottom cover 40 is rotated clockwise (leftward in FIG. 3(a)) with respect to the inner-container body 30 and the left end of the restricting protrusion 44 is brought into contact with the left end of the restricting recess 31B, the first through-hole 31A and the second through-hole 46 do not overlap (hereinafter referred to as the "container set state"). When the bottom cover 40 is rotated counterclockwise (rightward in FIG. 4(a)) with respect to the inner-container body 30 and the right end of the restricting protrusion 44 is brought into contact with the right end of the restricting recess 31B, the first through-hole 31A and the second through-hole 46 overlap to form a single communication hole α (hereinafter referred to as the refillable state). A gap S provided between the upper impregnated layer 51 and the lower impregnated layer 52 is disposed opposite the back of the refill hole α (inside the second storage section Q2) where the first through hole 31A and the second through hole 46 are connected.
In addition, in the container set state shown in Figures 3(a) and (b), the hinge 39 and the convex rib 45 are in an axially symmetrical relationship with respect to the container axis O1, but in the refillable state shown in Figures 4(a) and (b), the hinge 39 and the convex rib 45 are not in an axially symmetrical relationship with respect to the container axis O1.

Next, the inner container B with the impregnated body 50 accommodated in the second accommodation portion Q2 is attached to the outer container body 10 constituting the outer container A. Specifically, the inner container B is placed in the container set state shown in Fig. 3 (a) and (b), and the bottom lid 40 is fitted into the opening 11 of the outer container body 10. At this time, since the hinge 39 and the protruding rib 45 are in an axially symmetrical relationship with respect to the container axis O1, the hinge 39 on the inner container B side can be inserted into the hinge insertion portion 16 on the outer container body 10 side, and the protruding rib 45 on the inner container B side can be inserted into the rib insertion portion 17 on the outer container body 10 side, whereby the inner container B can be positioned in the circumferential direction relative to the outer container body 10.
At the same time, a plurality of engaging recesses 43 formed on the outer peripheral surface of the bottom cover 40 and a plurality of engaging protrusions 15 formed on the inner wall 14 of the outer container body 10 engage with each other, thereby restricting rotation of the bottom cover 40 relative to the outer container body 10.
Furthermore, by lifting the inner container B upward, the engagement between the locked recess 43 and the locking protrusion 15 can be released, making it possible to easily remove the inner container B to the outside of the outer container body 10.

When the inner container B is attached inside the outer container body 10 constituting the outer container A, the bottom lid 40 serves not only as the bottom of the inner container B, but also as the bottom of the outer container body 10, i.e., the bottom of the storage container 1.
In this storage container 1, the cosmetic tool P can be removed from the first storage section Q1 by opening the outer lid 20. Also, by opening the inner lid 35, the impregnated body 50 stored in the second storage section Q2 and provided below the inner flange 32 can be exposed and used. Since the hinge insertion section 16 and the hinge recess 13 are formed at positions shifted from each other by 90 degrees in the circumferential direction, the outer lid 20 and the inner lid 35 can be opened without interfering with each other.

Next, the refilling of the content liquid into the impregnated body will be described.
FIG. 5 shows an example of a refilling device containing a refilling liquid content, where (a) is a partial cross-sectional view showing the refilling device before the nozzle portion is assembled, and (b) is a partial cross-sectional view of the refilling device showing the assembly process.
5(a), the refilling tool 70 has a refilling tool body 70A in which a nozzle part 73 is erected via a neck part 72 formed in a reduced diameter on the upper part of a body part 71 filled with the content liquid, and a nozzle part 74 detachably connected to the tip of the nozzle part 73 via a breakable weakened part 75. A male screw part 73a is engraved on the outer circumferential surface of the nozzle part 73, and a female screw part 74a that meshes with the male screw part 73a is engraved on the inner surface of the base end side of the nozzle part 74. In addition, a pouring hole 76 is drilled in the side surface of the tip of the nozzle part 74, penetrating in the radial direction perpendicular to the nozzle axis O2.

To use the refill tool 70, as shown in FIG. 5(b), the nozzle portion 74 is torn off at the weakened portion 75 to open the tip of the nozzle portion 73, and then the nozzle portion 74 is inverted and the female threaded portion 74a on the base end side is screwed into the male threaded portion 73a on the nozzle portion 73 side, thereby connecting the nozzle portion 74 to the tip of the nozzle portion 73 and setting it into a usable state.
As for the storage container 1, the inner container B is lifted upward, the engagement between the locked recess 43 and the locking protrusion 15 is released, and the inner container B is removed to the outside of the outer container body 10. Alternatively, the inner container B may be removed to the outside of the outer container body 10 first, and then the refill tool 70 may be set to the use state.

Next, the bottom lid 40 of the removed inner container B is rotated counterclockwise (rightward in Figure 4(a)) relative to the inner container body 30, thereby setting the inner container B from the container set state to a refillable state in which the first through hole 31A and the second through hole 46 overlap to form a refill hole α.
Then, as shown in FIG. 6, the nozzle portion 74 is inserted horizontally into the second container portion Q2 through the refill hole α, and the tip of the nozzle portion 74 is inserted into the gap S between the upper impregnated layer 51 and the lower impregnated layer 52.

Here, if the thickness dimension of the lower impregnation layer 52 is set to be the same as the height positions of the first through hole 31A and the second through hole 46, this is preferable because it allows the height positions of the refill hole α and the gap S to match, allowing the tip of the nozzle portion 74 to smoothly enter the gap S.
Then, by pressing the body 71 while the nozzle portion 74 is inserted into the gap S between the upper impregnated layer 51 and the lower impregnated layer 52, the content liquid can be poured out from the pouring hole 76 provided in the nozzle portion 74 into the upper impregnated layer 51 and the lower impregnated layer 52. This allows the content liquid to be poured into the gap S between the upper impregnated layer 51 and the lower impregnated layer 52, which is the center of the impregnated body 50, and therefore it is possible to improve the impregnation of the impregnated body 50 without making the impregnated body 50 have a complicated shape as in the conventional case.

As shown in Figures 5(a) and 5(b), it is also preferable to provide an annular flange 78 that protrudes radially outward on the outer circumferential surface of the neck 72 of the refilling tool body 70A. In this configuration, when the nozzle portion 74 is inserted into the refilling hole α, the annular flange 78 functions to eliminate the gap that is likely to form between the refilling tool 70 and the inner container B side, so that the liquid content poured into the second storage portion Q2 can be prevented from flowing back and leaking out of the refilling hole α.

After refilling, it is necessary to return the inner container B to the outer container body 10 and reattach it, but if this is done while the refill hole α is open and in the refillable state, the hinge 39 and the protruding rib 45 are not axially symmetrical with respect to the container axis O1, so the inner container B cannot be attached to the outer container body 10. For this reason, when attaching the inner container B, it is necessary to return the inner container B from the refillable state to the container set state beforehand. In this way, since it is necessary to return the first through hole 31A and the second through hole 46 to a non-communicating state (a state in which the refill hole α is not formed) before attaching the inner container B, it is possible to reliably prevent leakage of the content liquid from the refill hole α.

Second Example
FIG. 7 is a cross-sectional view of a storage container showing a second embodiment of the present invention, where (a) is a longitudinal cross-sectional view of the storage container seen from the side, (b) is a longitudinal cross-sectional view from the direction of the arrow b-b in (a) (front side), FIG. 8 shows another example of a refilling tool, where (a) is a partial cross-sectional view showing the refilling tool, (b) is a half cross-sectional view showing the nozzle portion, (c) is a partial cross-sectional view showing the refilling tool with the nozzle portion attached, and FIG. 9 is a longitudinal cross-sectional view of the inner container showing the state during refilling in the second embodiment.

The storage container 1 shown in the second embodiment differs from the first embodiment in the configurations of the impregnated body 50 and the replenishing tool 70, but the other configurations and effects are the same as those of the first embodiment.
As with the first embodiment, the same reference numerals will be used to denote the same components, and the description thereof will be omitted.
As shown in Figures 7(a) and (b), in the storage container 1 of the second embodiment, the impregnated body 50 is configured to have two layers, an upper impregnated layer 51 and a lower impregnated layer 52, similar to the first embodiment described above.
A plurality of annular slits ST are formed concentrically at a predetermined radial interval on each opposing surface of the upper impregnated layer 51 and the lower impregnated layer 52 that constitute the impregnated body 50, and the upper impregnated layer 51 and the lower impregnated layer 52 that constitute the impregnated body 50 are contained in the second storage section Q2 in a stacked state with the opposing surfaces on which the annular slits ST are formed facing each other.

On the other hand, as shown in Fig. 8(a), the refilling tool 70 is formed by forming a refilling tool body 70A containing the content liquid to be refilled and a nozzle part 74 as separate members. The refilling tool body 70A is configured by integrally connecting a tearing part 77 to the tip of a nozzle part 73 via a breakable weakened part 75 in a separable manner. As shown in Fig. 8(b), the outer peripheral surface of the nozzle part 74 is provided with a plurality of pouring holes 76 drilled in a direction perpendicular to the nozzle axis O2. The plurality of pouring holes 76 are formed at the same predetermined intervals as the annular slits ST formed on the impregnated body 50 side along the nozzle axis O2 direction.
In addition, an annular flange 78 is formed on the outer peripheral surface of the neck portion 72 of the refilling device main body 70A. This seals the gap that is likely to form between the refilling device 70 and the inner container B when the nozzle portion 74 is inserted into the refilling hole α, thereby preventing the content liquid poured into the second storage portion Q2 from flowing back and leaking out of the refilling hole α.

The refill tool 70 shown in the second embodiment can be set into a usable state by tearing off the gripping portion 77 at the weakened portion 75 to open the tip of the nozzle portion 73, and then screwing the base end of the nozzle portion 74 onto the tip of the nozzle portion 73 to connect the two, as shown in Figure 8 (c).
9, in the same manner as in the first embodiment, the nozzle portion 74 is inserted into the second storage portion Q2 through the communication hole α formed by the first through hole 31A and the second through hole 46 communicating with each other, and the tip of the nozzle portion 74 is advanced into the gap S between the upper impregnated layer 51 and the lower impregnated layer 52. When the tip of the nozzle portion 74 has advanced into the gap S, the multiple pouring holes 76 formed in the nozzle portion 74 can be opposed to the annular slits ST formed in the upper impregnated layer 51 and the lower impregnated layer 52 that constitute the impregnated body 50.

Next, as in the first embodiment, when the barrel 71 of the refill device main body 70A is pressed and the liquid contents are poured out from the multiple pouring holes 76 into the gap S, the liquid contents poured out from the multiple pouring holes 76 can be made to directly enter each of the multiple annular slits ST formed in the upper impregnated layer 51 and the lower impregnated layer 52.
In this way, in the second embodiment, the content liquid poured out from the multiple pouring holes 76 of the nozzle portion 74 directly enters the annular slits ST formed in the upper impregnated layer 51 and the lower impregnated layer 52, respectively, thereby allowing the content liquid to be efficiently absorbed into the impregnated body 50 and improving the impregnation of the content liquid into the impregnated body 50.

The diameter of the multiple discharge holes 76 formed in the nozzle portion 74 is preferably gradually increased from the base end to the tip end of the nozzle portion 74. If the diameter of the discharge holes 76 is the same, the amount of liquid flowing through the nozzle portion 74 differs between the base end and the tip end, and the amount of liquid discharged from the discharge holes 76 tends to be greater at the base end and smaller toward the tip end. However, with this configuration, the amount of liquid discharged from each discharge hole 76 can be made approximately equal, so the content liquid can be discharged more evenly into each annular slit ST, and the impregnation of the content liquid into the impregnated body 50 can be further improved.

Although the configuration and the effects of the present invention have been described above based on the embodiments, the present invention is not limited to the above embodiments.
For example, in the above embodiment, the storage container 1 has been described as a compact container for storing a content liquid such as foundation, but the storage container 1 may be a container for storing other content liquids.
In the above embodiment, the impregnated body 50 is configured by stacking two layers, the upper impregnated layer 51 and the lower impregnated layer 52, in the height direction, but the embodiment of the present invention is not limited to the above embodiment and may be configured by stacking two or more impregnated layers. In this case, the refill hole α may be configured to be located opposite the gap S formed between any of the impregnated layers.
In the second embodiment, a configuration has been described in which the annular slit ST is formed on each of the opposing surfaces of the upper impregnated layer 51 and the lower impregnated layer 52, but it may also be formed on only one of the opposing surfaces.

The present invention can expand the range of applications in the field of storage containers with impregnated bodies.
