Description

  The present invention relates to a powdery cosmetic container that accommodates powdery cosmetics such as white powder and powder foundation and covers the opening side with an inner lid composed of an elastic silicon sheet or the like, and a partition portion that constitutes the inner lid The present invention relates to a powdery cosmetic container in which the powdery cosmetic can be taken out by pressing and extending to open a slit.

  Conventionally, a container having an applicator storage chamber for storing powdery cosmetics such as white powder and powder foundation as powder and storing an applicator such as a puff with a long bristle called a powder puff above it has been proposed. Yes. Many of these containers have a form in which an inner lid is placed over the powdery cosmetic and an applicator is placed on the inner lid. A mesh is stretched on the inner lid, and during use, the powdery cosmetic is applied to the applicator through the mesh of the mesh.

  However, the powdery cosmetic material may move more than necessary above the inner lid through the mesh, and the applicator may become powdery. This problem can be solved by fitting the cover above the inner lid to prevent the powdery cosmetic from moving above the cover, but it becomes cumbersome because it requires an operation to remove the cover during use. The number of parts also increased, causing a cost increase.

  Furthermore, recently, ultrafine particle type powdery cosmetics with finer powders have been provided due to the adhesiveness of the cosmetics, the covering power, and the good feel when the cosmetics are applied to the skin. This ultrafine particle type powdery cosmetic is more easily moved to the applicator storage chamber side. Powdered cosmetics such as white powder and powder foundation that have moved to the side of the applicator storage chamber are mobile phones with vibration that cause the cosmetic in the applicator storage chamber to scatter to the outside due to the flow of air when the lid of the container is opened. It was not suitable for.

Japanese Patent Laying-Open No. 2005-7093 (5th page, FIG. 2)

  In Patent Document 1, a part of the partition portion of the inner lid is formed into a sheet shape using silicon rubber having excellent elasticity. Furthermore, it is possible to take out powdery cosmetics by inserting countless cuts penetrating the front and back into the partition formed into a sheet shape and pressing the silicon sheet with an application tool such as a puff to expand the silicon sheet and open the cut. It is a thing. Further, when not in use, the cut is closed to prevent powder leakage to the applicator storage chamber side.

  According to the technique of Patent Document 1, when a silicon sheet is pressed with an applicator such as a puff, the silicon sheet is stretched to open a cut, and when not in use, the cut closes to prevent powder leakage to the applicator storage chamber side. However, since the silicon sheet has a cut, the stretching becomes non-uniform. This non-uniformity increases as it goes to the outer periphery of the partition portion, and there is a problem that the notch is torn when the distortion due to the extension is concentrated on the end of the notch.

  SUMMARY OF THE INVENTION An object of the present invention is to reduce stretching at the outer periphery of a partition portion made of a silicon sheet or the like, and prevent tearing due to stretching of the partition portion.

  In order to achieve the above object, the powder cosmetic container of the present invention forms a rib having an increased thickness on the back surface of the partition portion.

  That is, a container is provided with an inner lid, and a cosmetic storage chamber is provided below the inner lid to store powdery cosmetics such as white powder and powder foundation, and at least the partition that forms the inner lid is formed of a stretchable material. In the powdery cosmetic container in which innumerable cuts penetrating the front and back surfaces of the partition part are inserted and the partition part is extended to open the cut and take out the powdery cosmetic, the partition part presses the surface. The ribs formed concentrically so as to intersect with the extending direction to be extended, and the ribs formed by increasing the wall thickness concentrically with the notches are formed in the middle of the adjacent notches in the extending direction. It is formed on the back surface.

  The powdery cosmetic container of the present invention has the following effects. That is, the rib formed on the back surface of the partition portion is formed with an increased thickness, and is less stretched with respect to the stress than the portion without the rib. The ribs are formed concentrically with the notches, separating the partition portion into the inside and the outside, and dispersing stress and strain applied to the notches formed on the outside. Therefore, the non-uniformity of the stress transmitted to the notch in the outer peripheral portion is smaller than that without the rib, and even if the stress is concentrated at the end of the notch, the force is weak and does not cause the notch to be split.

  In addition, since the rib is provided on the cosmetic storage room side, even if the powdery cosmetic becomes lumpy by repeatedly pressing the sheet, the rib destroys the lumps and returns to the original powdery cosmetic There is also.

It is composition explanatory drawing of this invention powdery cosmetics container. It is single-piece explanatory drawing of the partition part concerning this invention. It is powder powder cosmetics taking-out explanatory drawing of this invention powdery cosmetic container.

  Hereinafter, it demonstrates based on the Example of this invention powdery cosmetics. FIG. 1 is an explanatory view of the structure of the powdery cosmetic container of the present invention, the left half shows a side view and the right half shows a side sectional view. In the figure, the container is composed of a container main body 1 that is open at the top and bottom and a fitting protrusion 53 that is formed integrally with the hack 5 and closes the lower opening side of the container main body 1. The container body 1 closes the top and bottom of the container body 1 with the partition portion 7 and the fitting protrusion 53 to form the cosmetic material accommodation chamber 13. The cosmetic storage chamber 13 stores the powdery cosmetic 100.

  The upper opening side of the container body 1 is provided with an upper edge 15 having a smooth upper surface and a reduced diameter portion 17 for fitting the outer ring portion 71 of the partition portion 7 on the outer periphery of the upper edge 15. Further, an engaging claw 11 for engaging the partition portion fixing member 3 is provided on the outer periphery of the upper portion of the container main body 1, and an engaging claw 12 for engaging the hook 5 is provided on the lower outer periphery. A cosmetic filling port 14 for filling the cosmetic storage chamber 13 with the powdery cosmetic 100 is opened on the lower opening side of the container body 1. The cosmetic filling port 14 is fitted and closed to the fitting projection 53. Further, the cosmetic filling port 14 is fitted with a fitting protrusion 53 having the center of the bottom surface of the hakama 5 protruding upward.

  The partition portion fixing member 3 clamps and fixes the partition portion 7 between the upper edge 15 of the container body 1 and also removes the powdery cosmetic 100 from the surface 77 of the partition portion 7 so that it can be transferred to a powder puff or the like. Open. Therefore, the upper part of the partition part fixing member 3 is provided with a collar part 31 that protrudes inward so as to cover the upper edge 15 of the container body 1 and opens the center of the upper end to form a powder outlet 33. Further, an engagement portion 35 is provided on the inner side surface of the partition portion fixing member 3 and is engaged and fixed to the engagement claw 11 of the container body 1.

  Hakama 5 covers the lower opening side of the container body 1 and the outer periphery of the fitting protrusion 53 in order to give the container design. The fitting protrusion 53 formed integrally with the hack 5 is fitted to the cosmetic filling port 14 of the container body 1 so that there is no powder leakage. Further, the engaging portion 51 formed on the inner surface of the hack 5 is engaged with the engaging claw 12 formed on the outer periphery of the lower portion of the container body 1 to prevent the fitting protrusion 53 from being inserted into the cosmetic filling port 14. It is fixed so that it does not come off.

  Next, the partition part 7 will be described with reference to FIG. 2A and 2B are explanatory views of a single part of the partition, in which FIG. 2A is a plan view and FIG. 2B is a side sectional view. The partition portion 7 is made of a stretchable soft elastic material such as silicon rubber. As shown in FIG. 2 (B), the central portion faces the thin sheet portion 79 having a flat surface and the back surface 75 on the outer periphery of the sheet portion 79. An outer ring portion 71 is formed in a letter shape. As shown in FIG. 1, the outer ring portion 71 is fitted on the reduced diameter portion 17 of the container body to close the upper opening side of the container body 1. Further, a ring-shaped protrusion 74 is formed on the upper part of the outer ring portion 71, and when the partition portion 7 is pressed and clamped between the container body 1 and the partition portion fixing member 3, Distortion confidentiality is provided along the lower surface of the portion 31.

  Further, as shown in FIG. 2A, linear cuts 73 a and 73 b are arranged in the sheet portion 79 along a plurality of concentric circles 76 so as to penetrate the front and back. A rib 72 is formed on the back surface 75 of the sheet portion 79 so that the thickness of the sheet portion 79 is increased in a ring shape, and the cuts 73 a and 73 b are separated into the outer peripheral side and the inner peripheral side of the rib 72. In FIG. 2A, the cuts 73a are arranged along one concentric circle, but this does not prevent the cuts 73a from being arranged along a plurality of concentric circles 76 as in the cut 73b.

  FIG. 3 is an explanatory view of taking out the powdery cosmetic. When the powder puff 200 is pressed, the sheet portion 79 of the partition portion 7 extends between the push-down center 77 that contacts the powder puff 200 and the upper edge 15 of the container body 1. The cut 73 is opened by the extension of the sheet portion 79, and the powdery cosmetic 100 in the cosmetic storage chamber 13 is taken out to the surface 77 of the partition 7 and can be transferred to the powder puff 200.

  At this time, since the cut direction of the linear cuts 73a and 73b arranged in a ring shape is arranged along a concentric circle 76 centering on the center of the seat portion 79 as shown in FIG. When the surface 77 of the part 7 is pressed downward, it intersects with the extending direction. Therefore, when the surface 77 of the partition part 7 is pressed downward, the notches 73a and 73b are opened, and a force to tear both ends of the notches 73a and 73b is applied according to the size of the openings.

  The opening of the cuts 73a and 73b by pressing the surface 77 of the partitioning portion 7 downward is due to the influence of the resistance due to the contact between the powder puff 200 and the powdery cosmetic 100 in the cosmetic storage chamber 13 and the sheet portion 79. The outer peripheral side tends to be larger. Further, since the sheet portion 79 has the cuts 73a and 73b, the stretching becomes non-uniform. This non-uniformity increases as it goes to the outer periphery of the partition part, and the distortion due to stretching tends to concentrate on the end part of the cut 73a and tear the sheet part. However, the portion forming the rib 72 of the sheet portion 79 is less stretched with respect to the tensile force than the portion not having the rib 72, and the rib 72 is formed concentrically with the notch 73 so that the sheet portion 79 of the partition portion 7 is formed. The rib 72 is separated into the inner side and the outer side, and the stress and strain applied to the cut 73a formed on the outer side are dispersed. Therefore, the stress concentrated on the end of the cut 73a in the outer peripheral portion becomes smaller than that without the rib 72, and does not reach the force for tearing the cut.

  The inventor of the present application conducted an extension test 1000 times for the partition portion 7 made of a silicon sheet, but the one without the rib 72 showed a slight tear in the notch 73a in the outer peripheral portion, but the one with the rib 72 was present. In the outer peripheral portion, no tear was seen in the cut 73a. Therefore, it has been confirmed that disposing the ribs 72 concentrically with the cut 73a has an effect of preventing the cut 73a from being torn.

  In addition, since the rib 72 is provided on the cosmetic storage chamber 13 side, even if the powdery cosmetic 100 becomes lumpy by pressing the sheet portion 79, the rib 72 and the fitting protrusion 53. There is also an effect that the dust can be destroyed and the powdery cosmetic 100 can be restored.

  As described above, the powdery cosmetic container of the present invention has the effect described in the column of the effect of the invention. In the above description, a single rib 72 has been described. However, a plurality of ribs 72 may be used.
