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 vibrations that cause the cosmetic in the applicator storage chamber to scatter to the outside due to the flow of air that opens the container lid 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 putting innumerable 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 expands to open a cut, and when not in use, the cut closes to prevent powder leakage to the applicator storage chamber side. However, at the time of stretching, the portion with the cut is easily stretched and the portion without the stretch is difficult to stretch, so the stretch becomes non-uniform depending on whether or not the silicon sheet is cut . In addition, the non-uniformity of extension is accumulated and increased toward the outside. The distortion due to the non-uniformity of the extension eventually concentrated on the end of the outermost notch, causing the notch to tear.

An object of the present invention is to reduce non-uniform stretching at the outer periphery of the partition portion (7) made of a silicon sheet or the like, and to prevent tearing of the notch (73) due to distortion of the partition portion (7). .

  In order to achieve the above object, the powdery cosmetic container of the present invention is formed with a rib (72) having an increased thickness on the back surface of the partition (7).

That is, the container is provided with an inner lid, and a cosmetic housing chamber (13) for housing powdery cosmetics (100) such as white powder and powder foundation is formed below the inner lid, and at least a partition portion (7 ) Is formed from a stretchable material, innumerable cuts (73) penetrating the front and back surfaces of the partition part (7) are inserted, and the cut (73) is opened by extending the partition part (7) to open a powdery makeup. In the powder cosmetic container in which the material (100) can be taken out, the partition (7) has a notch (73) arranged concentrically so as to intersect the extending direction that is extended by pressing the surface. The rib (72) formed concentrically with the notch (73) and having an increased thickness is independently formed on the back surface of the partition (7), so that the notch (73) is adjacent to the notch on the outer peripheral side. (73a) Partitioned in the circumferential side slit (73b), is not easily transmitted to the cut inner peripheral notches adjacent the causative strain of tearing (73) (73b) from the outer circumferential side slit (73a).

The powdery cosmetic container of the present invention has the following effects. Or ribs (72) formed on the rear surface of the partition part (7) is extended to stress than in a portion having no rib (72) in which is formed by increasing the wall thickness rather small, distortion yet small. The rib (72) is formed concentrically independently of the notch (73), and the notch (73) of the partition part (7 ) is separated into an inner notch (73b) and an outer notch (73a) . This makes it difficult to transmit uneven stress and strain on the outer peripheral side cut (73a ) from the peripheral cut (73b) . Therefore, the non-uniformity of the stress transmitted to the outer peripheral notch (73a) is smaller than that without the rib (72), and even if the stress is concentrated on the end of the outer peripheral notch (73a) , the force is weak and the outer peripheral side The cut (73a) will not be split.

  Moreover, since the rib (72) is provided in the cosmetics storage chamber (13) side, even if the powdery cosmetic (100) becomes lumpy by repeatedly pressing the partition (7), the rib ( 72) also has the effect of destroying lumps and returning to the original powdery cosmetic (100).

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 projection 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. On the lower opening side of the container body 1, a cosmetic filling port 14 for filling the cosmetic containing chamber 13 with the powdery cosmetic 100 is opened. Further, a fitting projection 53 is formed by fitting and closing the cosmetic filling port 14 with the center of the bottom surface of the hook 5 protruding upward.

  The partition part fixing member 3 clamps and fixes the partition part 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 part 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, It has distortion airtightness along the lower surface of the portion 31.

Further, as shown in FIG. 2 (A), linear notches 73 are arranged in the sheet portion 79 so as to penetrate the front and back along a plurality of concentric circles 76. The part no cut 73 of the back 75 of the seat portion 79 with thickened rib 72 cut 73 concentric wall thickness of the seat portion 79 in a ring shape, and is independently formed, the slit 73 into and out of the rib 72 The outer peripheral side cut 73a and the inner peripheral cut 73b are separated . In FIG. 2A, the outer peripheral side cuts 73a are arranged along one concentric circle, but this does not prevent the arrangement along the plurality of concentric circles 76 like the inner peripheral cuts 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 78 in contact with the powder puff 200 and the upper edge 15 of the container body 1. By extending the sheet portion 79, the outer peripheral side cut 73 a and the inner peripheral cut 73 b are opened, 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. become.

At this time, the cutting directions of the linear outer circumferential side cuts 73a and inner circumferential side cuts 73b arranged in a ring shape are along a concentric circle 76 centering on the center of the seat portion 79 as shown in FIG. Since they are arranged, when the surface 77 of the partition part 7 is pressed downward, it intersects with the extending direction. Therefore, the outer peripheral side cut 73a and the inner peripheral cut 73b are opened by pressing the surface 77 of the partition part 7 downward, and both ends of the outer peripheral cut 73a and the inner peripheral cut 73b are set according to the size of the opening. The tearing force works.

The opening of the outer peripheral side cut 73a and the inner peripheral cut 73b by pressing the surface 77 of the partition part 7 downward is the contact between the powder puff 200 and the powdery cosmetic 100 in the cosmetic storage chamber 13 and the sheet part 79. There is a tendency that the outer peripheral side becomes larger due to the influence of the resistance force and the like (because the powder puff 200 and the powdery cosmetic 100 are not touching the outer peripheral side of the sheet portion 79, there is nothing that hinders elongation) . In addition, since the sheet portion 79 has the cut 73 , when it is stretched, the portion with the cut is easy to stretch, and the portion without it is difficult to stretch, so the stretch becomes non-uniform depending on whether or not the silicon sheet is cut . This non-uniformity accumulates and increases as it goes to the outer periphery of the partition portion 7, and the distortion due to the non-uniform extension is eventually concentrated on the end of the outermost peripheral notch 73a and the sheet portion 79 is torn. There is a tendency. However, the portion of the sheet portion 79 that forms the rib 72 is less stretched with respect to the tensile force than the portion that does not have the rib 72, and the rib 72 is formed concentrically with the notch 73. The distortion due to non-uniform expansion of the inner peripheral cut 73b provided on the inner side of the rib 72 is absorbed and dispersed by the rib 72 before being transmitted to the outer peripheral cut 73a . 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 to tear the cut.

  In addition, the inventor of the present application conducted a 1000-fold extension test on the partition part 7 made of a silicon sheet. 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 housing 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.
