Description

  The present invention relates to a refill container in which a solid powder cosmetic in a contained inner dish is less likely to crack even when an impact due to dropping is applied.

  Conventionally, powder cosmetics such as foundations are used by filling the inner dish in a solidified state by a method such as casting or wet filling, and attaching it to a cosmetic container. In order to deal with cases where the product is sold without being used, or when the solid powder cosmetic in the medium dish mounted on the cosmetic container is used up, only the medium dish filled with the solid powder cosmetic is refilled as a so-called “refill”. It is carried out by storing in a container. And since this solid powder cosmetics, especially the cosmetics solidified by molding, are easily damaged by impact, those having a buffer property are used as refill containers.

For example, Patent Document 1 discloses a configuration in which the exposed surface of the solid powder cosmetic in the intermediate dish is attached to the intermediate dish, the lid portion protecting the exposed surface in the attached state, and the middle in the attached state. A mounting part having a holding part for holding the inner dish in a state in which the bottom surface of the dish is exposed; an engaging part that engages with the inner dish to prevent detachment; and an outer peripheral position of the holding part, A refill container comprising a folded portion formed so as to be continuously folded from a holding portion, and a refill container provided with a protruding portion protruding from the end portion at an end portion of the folded portion is disclosed. .
Further, by providing the protruding portion at the end of the folded portion, even if an external force is applied to the refill container in the direction facing the exposed surface, the mounting portion and / or the folded portion is elastic with the protruding portion as a fulcrum. It is described that the solid powder cosmetic filled in the inner dish can be reliably protected by deforming and absorbing external force.

However, recently, there is an increasing need for softer and softer solid powder cosmetics, and as described in Patent Document 1, it is difficult to prevent breakage of the solid powder cosmetics with conventional refill containers. It has become.
In particular, in the conventional refill containers including those described in Patent Document 1, in order to easily and reliably perform the operation of bending the refill container and taking out the intermediate dish from the refill container, An easy-bending part is formed by providing a side wall defect part in which a part of the side walls of two parallel sides is lost, but due to the structure of the side wall in the vicinity of the side wall defect part, an external force is generated by elastic deformation. Because it is difficult to absorb, when an impact is applied from the side of the side wall where the side wall defect portion is provided, the impact is easily transmitted to the inner plate, and the solid powder cosmetic material collapses from the site where the impact is applied. easy. And when the solid powder cosmetic is soft and soft, the frequency increases.

JP 2006-218032 A

  The present invention has a large shock-absorbing effect against the impact caused by dropping, and even when an impact is applied, particularly when an impact is applied from the side wall direction where the side wall defect portion is provided, the inner dish containing the solid powder cosmetic is stored. It is an object of the present invention to provide a refill container in which impact is not easily transmitted and, therefore, solid powder cosmetics do not easily collapse.

The present inventor has solved the above-mentioned problem by attaching a flange having a specific shape to the peripheral edges of the lower ends of the main body and the lid.
That is, the present invention comprises a main body having a main body side wall that rises from the peripheral edge and hangs down on the peripheral edge of the square bottom surface, and a lid body that has a lid side wall depending on the peripheral edge of the square lid surface. An easy-bending part is formed in the main body by providing a side wall defect part in which a part of the center part of each of the main body side walls of 2 to 4 sides including at least one set of two parallel sides out of the four sides is missing. In the refill container, a flange extending outwardly to each of the lower end periphery of the outer side wall of the main body and the lower end periphery of the lid side wall is attached to the outer side, and attached to the side of the flange provided with the side wall missing portion. The main body and the lid in a direction perpendicular to the bottom surface of the main body and the lid surface of the lid body, and the shape of the flange is a corrugated shape in which the valley portion is close to the side wall defect portion and has two or more peak portions. Refill with almost the same projected external shape It is a vessel.
The square means a rounded corner at the four corners as in the case of the conventional product.

  According to the present invention, the solid powder cosmetic has a very simple structure and has a large buffering effect against an impact caused by dropping, and even when an impact is applied, especially when an impact is applied from the side wall direction provided with the side wall defect portion. Thus, it is possible to provide a refill container in which impact is not transmitted to the inner dish in which the solid powder cosmetics are stored, and thus the solid powder cosmetic is not easily broken.

Hereinafter, the refill container of the present invention will be described with reference to FIGS.
1-3 is a figure which concerns on the main body 2 of the refill container of this invention, FIG. 1 is a top view, FIG. 2 is a side view, FIG. 3 is the sectional view on the AA line in FIG.
The main body 2 rises from the peripheral edge of the rectangular bottom surface 2a, folds and hangs down to form main body side walls 3a, 3b, 3c, and 3d. The main body side walls store and hold the inner dish. ing.
A side wall defect portion 3x in which a part of the side wall is missing is provided at the substantially central portion of the two main body side walls 3a and 3c which are parallel to each other, thereby forming an easily bent portion 8. ing. The easily bendable portion 8 is folded into a chevron by applying a force from the side of the main body side walls 3b and 3d when separating the inner tray, which is normally fixed to the bottom surface 2a by partial adhesion, from the main body side walls 3b and 3d. Facilitates the separation of the dishes.
Main body flanges 4a, 4b, 4c, and 4d are attached to the outer peripheral edges of the main body side walls 3a, 3b, 3c, and 3d.

The main body flanges 4b and 4d attached to the two sides not provided with the side wall defects have a constant width parallel to the lower edge of the main body side walls 3b and 3d, and the main body attached to the two sides provided with the side wall defects. The flanges 4a and 4c have a corrugated shape in which a valley portion is close to the sidewall defect portion 3x and has apexes of two or more mountain portions.
In the present invention, the apex of the crest means a point where a tangent parallel to the side wall and the flange are in contact with each other, and as illustrated in FIG. 1, the tangent T parallel to the main body side wall 3c and the end of the main body flange 4c. The two points 1P are in contact with the upper mountain portion. Although not shown, the same applies to the main body flange 4a. Therefore, each of the main body flanges 4a and 4c has two peak portions.
The outer sides of the main body side walls 3a, 3c on the two sides provided with the side wall missing portions are suspended to the same position as the horizontal position of the bottom surface 2a. Therefore, the main body flanges 4a, 4c extending outward from the lower ends thereof are Except for the portion bent downward, the horizontal position is substantially the same as the bottom surface 2a. On the other hand, the outer sides of the main body side walls 3b and 3d on the two sides that are not provided with the side wall deficient portions are suspended downward from the horizontal position of the bottom surface 2a. Therefore, the main body flanges 4b and 4d extending outward from the lower ends thereof are It is in a horizontal position below 2a.

4-6 is a figure which concerns on the cover body 5 of the refill container of this invention, FIG. 4 is a top view, FIG. 5 is a side view, FIG. 6 is the BB sectional drawing in FIG.
The lid 5 hangs down from the periphery of the rectangular lid surface 5a to form lid side walls 6a, 6b, 6c, 6d, and the lid side walls are in close contact with the outside of the main body side wall, 2 is covered with a lid 5.
Lid flanges 7a, 7b, 7c, and 7d are attached to the outer periphery of the lower ends of the lid side walls 6a, 6b, 6c, and 6d.

The main body 2 and the lid body 5 have a shape in which the projection shapes in the direction perpendicular to the bottom surface 2a of the main body 2 and the lid surface 5a of the lid body 5 are substantially the same. The lid flanges 7a and 7c have substantially the same shape, and the main body flanges 4b and 4d and the lid flanges 7b and 7d have substantially the same shape.
Therefore, as shown in FIG. 4, the lid flange 7c has two peak portions 2P in contact with the tangent line T. Although not shown, the lid flange 7a is the same.

FIG. 7 is a perspective view of the refill container 1 in a state in which an inner tray (not shown) is stored in the main body 2 and the lid body 5 is crowned, and the main body 2 and the lid body 5 are fitted and locked. It is fixed at part 9.
Of the body flange and lid flange, the body flanges 4a and 4c on the two sides provided with the side wall missing portions and the lid flanges 7a and 7c are in close contact except for both ends, but the side wall missing portions are provided. Since the two main body flanges 4b and 4d on the two sides are in a horizontal position below the bottom surface 2a, there is a vertical difference between the main body flanges 4b and 4d and the lid flanges 7b and 7d (H in FIG. 7). Is done.

In the refill container 1 of the present invention, the dimensions of the main body excluding the main body flanges 4a, 4b, 4c and 4d (dimensions in the plan view) are 54 to 62 mm in length and 48 to 56 mm in width. In order to obtain an impact buffering effect, the width (W1 in FIG. 1) of the body flanges 4b and 4d and the lid flanges 7b and 7d having a constant width shape is preferably 3.0 to 5.0 mm, and the corrugated shape is As for the widths of the main body flanges 4a and 4c and the lid flanges 7a and 7d, the maximum width (W2 in FIG. 1) is 3.0 to 6.0 mm, and the difference between the maximum width and the minimum width (W3 in FIG. 1). Is preferably 1.0 to 3.0 mm.
Further, as described above, when the two side flanges 4b and 4d that are not provided with the side wall defect portion are positioned below the horizontal position of the bottom surface 2a, the difference in the vertical direction (difference in horizontal position: FIG. 7). H) is preferably 1.0 to 4.0 mm.

  In the refill container of the present invention, even if an external force is applied from the side surface due to dropping or the like, the main body flange and the lid flange are elastically deformed to absorb the external force and buffer the shock transmitted to the inner tray. By providing a corrugated flange having a valley portion close to the sidewall defect portion and having apexes of two or more peaks on the side where the sidewall defect portion 3x is provided, to the middle dish through the sidewall defect portion It is possible to prevent the impact from being transmitted.

  Moreover, even if the main body flanges 4b and 4d on the two sides that are not provided with the side wall missing portion of the main body are positioned below the horizontal position of the bottom surface 2a, the flanges of the corresponding portions are elastic even when dropped in a horizontal state. By only deforming, it is possible to prevent external force from being transmitted to the bottom surface of the main body, and thus the bottom of the inner plate. Furthermore, as shown in FIG. 7, since there is a gap between the main body flanges 4b and 4d and the lid flanges 7b and 7d, it is easy to separate the main body and the lid body in order to take out the inner dish. There is also a secondary effect.

In addition, the refill container of this invention provided the side wall defect | deletion part in each of the main body side wall of 2-4 sides including at least 1 set of 2 parallel sides of 4 sides of a main body, FIGS. As shown in the example shown in Fig. 1, not only is a mode in which side wall defects are provided on a pair of two parallel sides, but a mode in which side wall defects are provided on three of the four sides, or side wall defects on all four sides. The aspect which provided this is also included.
Thus, the flange attached to the side where the side wall defect portion is provided has a corrugated shape.
On the other hand, the shape of the flange attached to the side in the case of having a side where the side wall missing portion is not provided is the shape of the main body side walls 3b and 3d as in the flanges 4b and 4d in the example shown in FIGS. Although it has a constant width shape parallel to the outer peripheral edge of the lower end, it may be a corrugated shape in which the valley portion is close to the central portion of the main body side wall, similar to the flanges 3a and 3c attached to the side where the side wall missing portion is provided. Absent.

  FIG. 8 is a plan view of the main body in a mode in which side wall defects are provided on all four sides, and therefore all flanges have a corrugated shape. Side wall defect portions 3x are provided at almost the central portions of all of the main body side walls 3a, 3b, 3c, and 3d, thereby forming two easy-to-bend portions 8 in the vertical and horizontal directions. Therefore, even if a force is applied from the side of the main body side walls 3a and 3c, and conversely, a force is applied from the side of the main body side walls 3b and 3d, it is folded into a chevron at the easily bent portion 8 to facilitate separation of the inner plate. be able to.

Although not directly related to the buffer effect, as another embodiment, as shown in FIG. 9, the four corners of the flange of the main body 2 (near the boundary between the main body flanges 4a and 4b, near the boundary between the main body flanges 4b and 4c, By providing the rib 10 in the vicinity of the boundary between the flanges 4c and 4d and in the vicinity of the boundary between the main body flanges 4d and 4a, and floating on the rib, it is possible to obtain an effect of facilitating the cartoner in the manufacturing process at the factory. .
Since FIG. 9 is the same as FIG. 1 except that the rib 10 is provided, the reference numerals are omitted.

  As described above, in the examples shown in FIGS. 1 to 7, the main body flanges 4b and 4d are positioned in a horizontal position below the bottom surface 2a, but this is not always necessary, and the main body side walls 3a, 3b, The outer sides of 3c and 3d are suspended at any part to substantially the same horizontal position as the bottom surface 2a. Therefore, all of the main body flanges 4a, 4b, 4c and 4d may be present at the same horizontal position as the bottom surface 2a. Absent.

The refill container of the present invention is manufactured by heat-softening a sheet of thermoplastic resin having a thickness of about 0.2 to 0.6 mm and thermoforming it by a method such as vacuum forming, pressure forming, or press forming. Is appropriate.
Examples of the thermoplastic resin include polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyolefins such as polystyrene, polypropylene and polyethylene, and biodegradable plastics such as polycarbonate, vinyl chloride, polyvinyl alcohol and polylactic acid.

  The refill container of the present invention can be used for any intermediate dish of a press-processed metal plate such as aluminum or stainless steel or a resin such as polyethylene terephthalate or acrylonitrile-styrene copolymer. .

Example 1
A powder foundation comprising each component shown in Table 1 was prepared.
In the preparation, the powder components (1) to (7) are uniformly mixed with a Henschel mixer, and the preservative (8), the oil agent components (9) to (11), and the aqueous dispersion of the silicone elastomer (12). Then, the mixture was mixed again until uniform, and the resulting mixture was placed in a hot air dryer, dried at 50 ° C. for 4 hours, filled in a pan and press-molded.

A refill container having a shape shown in FIGS. 1 to 7 obtained by thermoforming a polyethylene terephthalate sheet having a thickness of 0.3 mm by vacuum forming, and made of aluminum filled with the solid powder cosmetic obtained above. An intermediate dish (mass 9.5 g) was housed and a drop test was performed.
1 to 3, the outer diameter of the portion excluding the flange is 57.8 mm in the vertical direction and 51.3 mm in the horizontal direction, and the inner diameter of the outer wall of the main body, that is, the inner diameter of the portion storing the inner dish is The vertical direction is 52.3 mm and the horizontal direction is 45.8 mm. The body flanges 4b and 4d have a width (W1 in FIG. 1) of 3.5 mm, and the body flanges 4a and 4c have a maximum width (W2 in FIG. 1) of 3.5 mm and a minimum width (W3 in FIG. 1) of 2. 0.0 mm.

  The height of the main body side walls 3a, 3b, 3c, 3d from the bottom surface 2a is 7.0 mm, and the horizontal position of the main body flanges 4b, 4d is 2.0 mm below the horizontal position of the bottom surface 2a. The horizontal position of the part except the part bent below both ends of 4c is the same as the horizontal position of the bottom face 2a.

The drop test was performed for each of five samples by the following method. P-tile (vinylidene chloride) was used as the flooring to receive the sample.
Longitudinal direction: Repeating dropping from a height of 20 cm with either one of the two sides not provided with a side wall defect until a crack occurs (however, up to 40 times) And recorded the number of drops until cracking occurred.
Lateral side direction: Repeating dropping from a height of 20 cm with one of the two sides provided with a side wall defect part down until cracks occur (however, the limit is 40 times) And recorded the number of drops until cracking occurred.
Erecting direction: In a horizontal state, dropping from a height of 40 cm was repeated until a crack occurred (however, up to 20 times), and the number of drops until the crack occurred was recorded. .
The results are as described in Table 2. For example, “40+” indicates that no cracking occurred even when dropped 40 times.

Comparative Example 1
A comparative refill container having a shape shown in FIGS. 10 to 16 obtained by thermoforming a polyethylene terephthalate sheet having a thickness of 0.3 mm by a vacuum forming method (in general use in the past) is described in Example 1. A drop test similar to the method performed was performed.
10 to 16, the shape of the body flanges 14a and 14c is different from the shape of the body flanges 4a and 4c of the shape of the refill container shown in FIGS. The point that the width (W2 in FIG. 10) is a constant width of 3.5 mm except that it cuts in the direction of the defect, and the main body flanges 14a, 14b, 14c, and 14d are all in the same horizontal position as the bottom surface 12a. And the shape of the main body flanges 14a, 14b, 14c, 14d and the shape of the lid flanges 17a, 17b, 17c, 17d are made a little misaligned at the four corners and the portions cut in the side wall missing portions, so that they can be easily opened. Except for this point, all have the same shape as the refill container having the shape shown in FIGS.
The test results are as described in Table 2.

  As is clear from Table 2, the shape of the flange is the same for the fall in the vertical side direction, so the results of Example 1 and Comparative Example 1 are almost the same, but the drop in the horizontal side direction. On the other hand, in Comparative Example 1, the number of occurrences of cracks was 11 on average, and cracks occurred early, whereas in Example 1, there were three samples that did not crack even after 40 drops. The average value was 35 times or more, and the buffering effect was 3 times or more. In addition, a difference in effect is exhibited even when falling in an upright direction.

  The refill container of the present invention has a large buffering effect against impact caused by dropping, and even when an impact is applied, even when an impact from the side wall direction provided with an easily bent portion is applied, the solid powder cosmetic is accommodated. Suitable for use as a refill container for powder cosmetics such as foundations, where impact is not transmitted to the inner dish, and therefore, solid powder cosmetics are less likely to collapse and tend to be softer and softer. It is done.
