  The cosmetic needs to be firmly fixed in the cosmetic container and to withstand an impact such as when the container is dropped. However, when the cosmetic container is composed of the container main body and the inner plate for the purpose of meeting such a requirement, the manufacturing cost of the cosmetic container inevitably increases. In a scene where it is desired to simplify a container in which cosmetics are provided as a sample, it is difficult to prevent the cosmetics in the container from collapsing even when an external force is applied when using a container with reduced manufacturing costs.

  This invention is made | formed in view of such a subject, and makes it a subject to provide the cosmetics container which can fix firmly the cosmetics to accommodate with a simple structure.

  In order to solve the above-mentioned problems, the present invention is configured by forming the storage portion with a foam so that the wall surface of the storage portion is formed into a porous surface, and this foam reduces the impact transmitted from the outside to the storage portion. It was.

  Specifically, a cosmetic container having a concave storage portion filled with cosmetics, the main body portion provided with a through hole forming a wall surface of the storage portion, and the main body so as to close the through hole A bottom portion that forms a bottom surface of the storage portion, and the main body portion is formed in a porous surface that bites the wall surface of the storage portion, and the main body portion of the main body portion. It was assumed to be composed of a foam that alleviates the impact transmitted from the outside to the storage section side.

  In this cosmetic container, the wall surface of the storage portion is formed in a porous shape. Therefore, the cosmetic stored in the storage unit enters the hole in the wall surface. Accordingly, the cosmetic bites into the hole, and the cosmetic bites into the wall surface. Thereby, even if an external force such as an impact is applied to the cosmetic container, the cosmetic is unlikely to come off from the storage unit.

  In addition, the cosmetic container also has a function of mitigating the impact that the foam constituting the main body portion transmits from the outside of the main body portion to the storage portion side. Therefore, even if an impact is applied to the cosmetic container, the impact transmitted to the cosmetic in the storage unit is reduced. Thereby, even if external force, such as an impact, is applied to the cosmetic container, the cosmetic is unlikely to collapse.

  By adopting such a configuration, the cosmetic container can firmly fix the cosmetic to be stored with an extremely simple configuration.

  The cosmetic stored in the storage unit is solidified by being filled while being compressed in the storage unit, and the main body has a hardness substantially the same as the hardness of the cosmetic after filling. It may be composed of a foam. If the hardness of the cosmetic after filling and the hardness of the foam are substantially the same, even if the relationship between the cosmetic and the foam exerts a force, the foam is solidified because they are of the same hardness. Hard to break down cosmetics. Therefore, after the powdery cosmetic is put into the storage portion and compressed and solidified, the compressive force is released, and the foam does not break the cosmetic even if the cosmetic or the foam returns to its original shape due to elasticity. . The hardness referred to here is a quantitative expression of the amount of deformation with respect to an external force. For example, the hardness is the amount of displacement of a rod when a rod with a sharp tip is pressed against a sample with a predetermined load.

  The main body may be a plate-like member provided with one or a plurality of the through holes. According to this, a desired number of storage parts can be provided with a very simple configuration.

  Moreover, the adhesive sheet member affixed on the back surface of the said main-body part may be sufficient as the said bottom part. According to this, since the bottom surface of the storage unit becomes an adhesive surface, the cosmetic stored in the storage unit is more firmly fixed in the storage unit, and the configuration of the cosmetic container itself is extremely simplified. Can do.

  It is possible to provide a cosmetic container in which the cosmetic to be stored can be firmly fixed with a simple configuration.

Hereinafter, embodiments of the present invention will be described. Embodiment described below shows the embodiment of this invention exemplarily, and this invention is not limited to such embodiment.

  A top view of the cosmetic container 10 according to the present embodiment is shown in FIG. 1, and a bottom view thereof is shown in FIG. As shown in FIGS. 1 and 2, the cosmetic container 10 includes a foam sheet 11 (corresponding to a main body portion in the present invention), an adhesive sheet 12 attached to the bottom of the foam sheet 11 (in the bottom portion in the present invention). Equivalent), and a transparent film 13 covering the foamed sheet 11.

  The foamed sheet 11 is provided with six through holes 14, and the through holes 14 form a wall surface 17 of the storage portion 15 that stores cosmetics. The foam sheet 11 is a Miraboard (registered trademark) made of a foam having a foaming rate of 10 to 18 times, and is a mixture of PS (polystyrene) of 94 to 99 wt% and butane of 1 to 6 wt%. The foamed sheet 11 may have a main component of PE (polyethylene) or PU (polyurethane). Moreover, the thickness of the foamed sheet 11 is about 3-8 mm. The foam sheet 11 has such a strength that it does not deform even if the powder placed in the storage portion 15 is compression molded. In addition, the foaming rate as used in this application is the value which remove | divided the volume before a foaming process from the volume after a foaming process.

  The adhesive sheet 12 is a sheet coated with an adhesive on one side, and is attached to the back surface of the foamed sheet 11 so as to close the through hole 14, thereby forming the bottom surface 18 of the storage unit 15.

  The transparent film 13 is a rectangular and transparent film sheet that covers the surface of the foam sheet 11, and one end in the longitudinal direction is bonded to the foam sheet 11 with an adhesive. The other end is also detachably attached to the foam sheet 11 with an adhesive. On the other end side, a knob 19 for picking with a finger is provided. Therefore, as shown in FIG. 3, the user can open and close the transparent film 13 that functions as a lid of the storage unit 15 by picking the knob 19 with a finger and attaching or peeling the transparent film 13 on the foam sheet 11. It is.

  FIG. 4 is a cross-sectional view of the cosmetic container 10 taken along the line AA. Since the foam sheet 11 is a porous body, the wall surface 17 of the storage portion 15 is formed in a porous shape as shown in FIG. For this reason, when the powder is put into the storage portion 15 constituted by the porous wall surface 17 and the bottom surface 18 where the adhesive surface of the adhesive sheet 12 is exposed, the powder enters the hole of the wall surface 17 and The cosmetic is filled in a state of being adhered to the bottom surface 18. Therefore, the cosmetic is securely fixed in the storage unit 15.

  According to the cosmetic container 10, the impact of the foam sheet 11 transmitted from the outside of the cosmetic container 10 into the storage unit 15 is reduced without using a conventionally used middle dish. Further, since the cosmetic is firmly fixed to the porous wall surface 17, even if an impact is transmitted from the outside of the cosmetic container 10 into the storage unit 15, the cosmetic does not easily jump out of the storage unit 15. In addition, when it is desired to individually store a plurality of types of cosmetics such as different colors, the storage portions of the respective cosmetics can be easily separated by providing the foamed sheet 11 with a number of holes corresponding to this. Moreover, if the lower surface of the adhesive sheet 12 is used as a printing surface, it is possible to add a description of the cosmetic without increasing the number of members. Therefore, it is possible to achieve the solid cosmetic fixing performance and body impact performance required for the cosmetic container at an extremely low manufacturing cost. Therefore, for example, it is extremely useful when a cosmetic is desired to be provided as a sample.

The surface of the foam sheet 11 may be a slide type lid instead of the transparent film 13. FIG. 5 shows a perspective view of a cosmetic container 10 ′ using a sliding lid. Unlike the cosmetic container 10 described above, the cosmetic container 10 ′ includes a tray-type slide lid 23 that is vacuum-formed instead of the transparent film 13, and the foam sheet 11 is formed in a groove 33 that extends in the longitudinal direction. It is configured to fit. FIG. 6 is a diagram illustrating a method for opening and closing the slide lid 23 of the cosmetic container 10 ′. When using the cosmetics stored in the storage unit 15, the slide lid 23 is attached as shown in FIG.
Open and close as shown in. According to this cosmetic container 10 ′, the foam sheet 11 can alleviate the impact transmitted from the outside of the cosmetic container 10 ′ into the storage portion 15, and can also enhance aesthetics.

  Next, a second embodiment will be described. FIG. 7 shows a top view of the cosmetic container 20 according to the second embodiment. As shown in FIG. 7, the cosmetic container 20 has six inner dishes 31 arranged in a housing 32. FIG. 8 is a view showing a method for assembling the cosmetic container 20. As shown in FIG. 8, the cosmetic container 20 has six inner dishes 31 prepared separately from the casing 32 and bonded to the bottom surface 28 of the casing 32 with an adhesive.

  A top view of the inner plate 31 is shown in FIG. 9, and a bottom view is shown in FIG. As shown in FIG. 9 and FIG. 10, the inner dish 31 includes a foam sheet 21 and an adhesive sheet 22 attached under the foam sheet 21.

  The foam sheet 21 is provided with a through hole 24, and the through hole 24 forms a wall surface 27 of a storage unit 25 that stores cosmetics. The foamed sheet 21 is a foam having a foaming ratio of 10 to 18 times, and the main component is PS (polystyrene), but the main component is PE (polyethylene) or PU (polyurethane). It is good.

  The adhesive sheet 22 is a sheet in which an adhesive is applied on one side, similar to the adhesive sheet 12 described above, and is attached to the back surface of the foamed sheet 21 so as to close the through hole 24, whereby the bottom surface 28 of the storage unit 25. Form.

  FIG. 11 is a cross-sectional view of the cosmetic container 20 taken along the line BB. Since the foam sheet 21 is a porous body, the wall surface 27 of the storage portion 25 is formed in a porous shape as shown in FIG. For this reason, when powder is put in the storage unit 25 and molded, the cosmetic material is securely fixed in the storage unit 25.

  According to the cosmetic container 20, since the inner plate 31 is bonded to the housing 32, the impact transmitted from the outside of the cosmetic container 20 to the storage unit 25 is reduced, and the foam sheet 21 itself Reduces the impact transmitted from the exterior of the cosmetic container 20 into the storage unit 25. Therefore, the fixing performance and impact resistance performance of the solid cosmetic required for the cosmetic container can be realized at a relatively low cost. Moreover, if the inner dish filled with cosmetics is rearranged, a wide variety of cosmetics can be provided to customers.

In addition, about the cosmetic container which concerns on said each embodiment, since the experiment which compares what changed the foaming rate and thickness of the foam sheet was performed, this result is demonstrated. The table shown below shows the results of this experiment.

  As shown in the above table, a drop test and a twist test were performed on foamed sheets having thicknesses of 3 mm and 5 mm with foaming rates of 5 times, 10 times, 18 times, and 20 times. The sample shown for six colors corresponds to the cosmetic container 10 according to the first embodiment described above, and the sample shown for one color corresponds to the cosmetic container 20 according to the second embodiment. To do.

In the above test, for a sample of six colors of powdered cosmetics placed in the storage unit, for example, a BORE diameter (inner diameter) of 80φ is set with a hydraulic cylinder for pressing, and a pressing pressure of 20 kg / cm ² (
(Total force is about 1000kg) For one color sample, press pressure 10kg / cm ²
The product is compression molded. As can be seen from the table, when the foaming ratio is 20 times, good results are obtained with respect to impact resistance against dropping, but on the other hand, the rigidity against twisting is weakened, so that the cosmetics are likely to collapse. In addition, when the foaming rate is 5 times, the rigidity against twisting is strengthened so that the cosmetics are not easily collapsed. On the other hand, the impact at the time of dropping is easily transmitted to the cosmetics, and the cosmetics are more likely to collapse than those with a foaming rate of 20 times. The result was obtained. However, depending on the characteristics of the contents (those with a lot of oil, etc., or eye colors with high contents hardened by increasing the press pressure), even those with a foaming rate of 5 times may not collapse easily. is there. On the other hand, when the foaming rate was 10 times and 18 times, the result was obtained that the cosmetic material did not collapse with respect to both the impact resistance and the twist. From these results, if the expansion ratio is 10 to 18 times, it is possible to achieve both the fixing performance and the body impact performance of the solid cosmetic. In addition, the impact resistance performance with respect to the drop is based on the assumption that the camera has fallen from a table, a heel, or the like, and is the impact resistance performance with respect to the fall assumed in daily life. Moreover, the rigidity with respect to the twist assumes a load applied when a puff or the like is pressed against the cosmetic or when the cosmetic container is gripped, and is the rigidity with respect to the twist assumed in daily life.

Moreover, about the cosmetic container which concerns on each said embodiment, the measurement result of the hardness of a foam sheet is as showing in the following table | surface.

The hardness of the foamed sheet was measured by applying a load of 2 pounds with an Olzen hardness tester. The softer the larger the amount of deformation, the larger the hardness value, and the harder the smaller the amount of deformation, the hardness value. Is displayed to be smaller. As is apparent from the table, the higher the foaming rate of the foamed sheet, the softer, and the lower the foaming rate, the harder. Here, since the cosmetic container according to each of the above embodiments is a container in which the cosmetic is filled and compression-molded, if the hardness of the cosmetic and the hardness of the foamed sheet are substantially the same, It is possible to prevent cracking of the powder after compression caused by deformation when the foamed sheet is compressed. For example, since the hardness of pressed solid powder and cheek color is Hs 25 to 27, it is preferable to apply a foam sheet (sample Nos. 3 and 4) having the same hardness. Moreover, since the hardness of powder foundations of powder solid and interesting is Hs36-40, it is preferable to apply the foam sheet (sample No. 1 and 2) which has the hardness equivalent to this. In each of the above embodiments, by applying a foam sheet having a hardness according to the cosmetic to be stored, the filled cosmetic does not crack, and the cosmetic has a very low fixing performance and body impact performance. It can be realized at a cost. The foaming rate and hardness of the foamed sheet are in a trade-off relationship, and the hardness depends on the components of the foamed sheet. For this reason, the component and foaming rate of the foam sheet to be used are suitably selected according to the type of cosmetic to be stored.

  In addition, when compression-molding cosmetics, the adhesive sheet affixed on the lower surface of the foam sheet is supported by the apparatus which performs compression molding. Taking the case of the cosmetic container 10 according to the first embodiment as an example, a series of processes from the production of the cosmetic container to the filling of the cosmetic will be described. A schematic diagram of these steps is shown in FIG.

  A series of processes from the production of the cosmetic container to the filling of the cosmetic starts with the cutting out of the foam sheet 11 as shown in FIG. That is, the foam plate 34 is set in a punching die prepared in advance, and the foam sheet 11 is cut out from the foam plate 34. Since the foam sheet 11 is formed by cutting the foam plate 34 in this way, the wall surface 17 of the storage portion 15 formed by the through hole 14 becomes a porous surface. Next, as shown in FIG. 12B, the adhesive sheet 12 is attached to the lower surface of the foam sheet 11 so as to close the through hole 14 provided in the foam sheet 11. Next, as shown in FIG. 12 (c), cosmetic powders are put into the six storage portions 15 constituted by the adhesive sheet 12 and the foamed sheet 11, respectively. Next, as shown in FIG. 12D, the powder put in the storage unit 15 is compressed by a press. The compression pressure at this time is appropriately determined according to the ingredients of the cosmetic. Next, as shown in FIG. 12 (e), a transparent film 13 is affixed to the upper surface of the foam sheet 11 so as to cover each storage portion 15.

  By the series of processes described above, a cosmetic package in which the cosmetic container is filled with the cosmetic is completed. In addition, in the cosmetic container 10 which concerns on 1st embodiment, although the accommodating part 15 was formed in the half-moon shape, you may form roundly as shown, for example in FIG. However, the half-moon shape of the storage unit 15 is suitable for the case where cosmetics are provided as a sample for sample because the inner volume is reduced and the shape of the storage unit 15 follows the movement of the finger. In addition, since the cosmetic material near the center of the storage unit 15 is closer to the wall surface 17 when the storage unit 15 is formed in a half-moon shape than the circular shape, the cosmetic material is surely contained in the storage unit 15.
