A function to prevent this is required. For this reason, as a thing which can prevent a crack etc. of cosmetics, for example, a container (for example, refer to patent documents 1) which provided a buffering material in the bottom in order to absorb shock etc., and the bottom in a double structure Various containers such as a container (see, for example, Patent Document 2) have been proposed.

Japanese Utility Model Publication No. 7-20108 Japanese Patent Laid-Open No. 2004-97806

  However, in the case where the cushioning material is provided on the bottom surface as described above, the number of parts increases and the management side such as inventory management becomes complicated. Moreover, since the space which arrange | positions this on a container bottom face is required, a container enlarges. And in the thing which made the bottom face a double structure, since the extra cost and labor are required for the manufacture, the further improvement is calculated | required.

  The present invention has been made in view of such circumstances, and can absorb impacts and the like when dropped, etc., and can be easily manufactured at low cost, has a small number of parts, and can be miniaturized. The purpose is to provide a cosmetic container.

  In order to achieve the above object, a cosmetic container according to the present invention includes a container main body in which an accommodation concave portion for accommodating an inner dish filled with cosmetics is formed, and a lid that covers the container in a freely openable / closable manner. Provided, a notch extending along the peripheral edge is formed in a portion facing the peripheral edge of the bottom surface of the housing recess, and a portion of the bottom surface inside the notch forming portion has the inner dish placed thereon. The gist of the invention is that it is bent and deformed in a state, and that a suppression means for suppressing the bending of the inner portion of the bottom surface is provided.

  In the cosmetic container of the present invention, a notch extending along the peripheral edge is formed in a portion of the container body opposite to the peripheral edge of the bottom of the housing recess, and a portion of the bottom surface inside the notch forming portion is above it. In addition, the inner plate is bent and deformed in a state where it is placed and held. Therefore, when an impact or the like is applied to the container main body, the inner side of the bottom surface of the housing recess can be bent vertically and horizontally with the portion other than the notch as an axis, and the impact or the like can be absorbed. Moreover, since the suppression means which suppresses the bending of an inner part of a bottom face is provided, the movable range of the bending of the inner part of the bottom face can be kept within a certain range, and damage to cosmetics due to excessive bending can be prevented. it can. Therefore, even if the cosmetic container of the present invention is accidentally dropped on the floor during transportation or use, or accidentally applied to another object while being carried, the impact etc. may cause The contained cosmetic is prevented from cracking or breaking. Moreover, in the cosmetic container of the present invention, unlike the conventional example, there is no need to use a cushioning material as a separate member, and the cushioning material is formed so as to be integrated, so the number of parts is small, and management such as inventory management is performed. The surface is simplified. Further, it is not necessary to provide a space for incorporating a separate cushioning material in the housing recess, and accordingly, the entire container can be reduced in size. Furthermore, in the cosmetic container of the present invention, unlike the conventional example, it is not necessary to have a double bottom structure, so that the container body can be made thinner and lower in cost.

  Further, in the present invention, when the suppressing means is provided on the wall surface of the housing recess, the range of the bottom surface can be more reliably set within a certain range.

  In the present invention, “providing suppression means” means not only a case where the suppression means is added to the container main body having the housing recess, but also a cosmetic without providing the suppression means in the container body itself. Including the case where the bottom surface of the inner dish or the like filled with is set so that the bottom surface of the housing recess of the container main body can be brought into contact with each other to exert a suppressing effect.

  Next, an embodiment for carrying out the present invention will be described. However, the present invention is not limited to this embodiment.

  FIG. 1 is a perspective view of a compact container which is an embodiment for carrying out the present invention, wherein 1 is a container body and 2 is a lid. The container body 1 has a substantially square shape in a plan view and is made of polyethylene terephthalate (hereinafter referred to as “PET”). The lid 2 has a shape that covers the entire top surface of the container body 1 and is also made of PET. A hinge portion (not shown) projects downward from the rear end portion of the lid 2, and this hinge portion engages with the rear end portion (not shown) of the container body 1. Thus, the lid body 2 is opened upward. In FIG. 1, each part is schematic and is different from the actual size, thickness, etc. (the same applies to the following figures).

  As shown in FIG. 2, the container body 1 is provided with a housing recess 3 for housing a metal dish 5 filled with cosmetics on the back side, and a cosmetic tool (not shown) such as a chip or a brush. A rectangular tube-shaped cosmetic tool receiving recess 4 is provided on the front side. Then, the inner dish 5 is accommodated in the accommodating recess 3 from above as shown in the drawing, and the bottom surfaces of the inner dishes 5 are bonded and fixed integrally with hot melt or the like. FIG. 3 is a perspective view of the container body 1 as viewed from the back side.

  4 and FIG. 5 when viewed from the back side, and FIG. 6A, which is a sectional view taken along line XX of FIG. 2, and FIG. 6B, which is a plan view of FIG. This will be described in more detail with reference to the drawings. That is, the housing recess 3 is formed in a dish-like shape having a substantially rectangular shape in plan view, which includes the bottom surface 7 and the peripheral wall 6. The bottom surface 7 has notches 9a and 9b having a width of about 0.3 mm extending along the peripheral edge of the peripheral edge of the bottom surface 7 facing each other, and is in contact with the central portions of the left and right peripheral walls 6a and 6c. The notches 9a and 9b are interrupted at two portions (7α and 7α ′), and the inner portion of the bottom surface 7 is connected to the peripheral wall 6 at the two portions (7α and 7α ′). Further, the lower end on the bottom surface 7 side of the peripheral wall 6b on the back side and the peripheral wall 6d on the front side (in FIG. 6, the front-rear direction of the container body 1 is arranged in the left-right direction) protrudes toward the inside of the housing recess 3. Suppressing portions 8a and 8a ′ are provided.

  Such a container main body 1 can be obtained as follows, for example. That is, first, the PET resin composition is mixed and may be molded as it is or after being pelletized, and can be molded by injection molding, vacuum molding, or the like. The thickness of both the bottom surface 7 and the peripheral wall 6 is as thin as about 1 mm, and the whole has flexibility.

  According to this configuration, the container body 1 is formed of flexible PET, and the notches (9a, 9b) are formed at the two opposing positions on the peripheral edge of the bottom surface 7 so that the above-mentioned cut of the bottom surface 7 is formed. The inner part surrounded by the notches 9a and 9b has a so-called double-sided cantilever structure. For this reason, when an impact or the like is applied to the container body 1, the inner portion of the bottom surface 7 with respect to the notch forming portion is placed and held on the inner tray 5 (the inner tray 5 is hot melted on the bottom surface 7. In the state of being fixed with an adhesive), it can be bent vertically and horizontally with the portions 7α and 7α ′ connected to the peripheral wall 6 as an axis to absorb the impact and the like. Further, since the bottom surface 7 is formed to be thin with a thickness of about 1 mm, the bottom surface 7 is more easily bent and can further absorb an impact or the like when dropped.

  And since the suppression part 8a, 8a 'which protrudes inside the accommodation recessed part 3 is provided in the lower end by the side of the bottom face 7 of the surrounding wall 6, even if an inner part bends too much rather than the notch formation part of the bottom face 7, Since the bending deformation is suppressed by hitting the suppressing portions 8a and 8b, the bending of the bottom surface 7 can be more surely kept within a certain range, and the cosmetic material can be prevented from being damaged by excessive bending. Incidentally, the gap P between the suppression portions 8a, 8b and the bottom surface 7 (see FIG. 6A) is formed to be 0.6 mm, so that the deflection of the bottom surface 7 is within this range. Furthermore, unlike the conventional cosmetic container, it is not necessary to use a cushioning material as a separate part, and the cushioning material is formed so as to be integrated, so that it can be easily produced at low cost. Further, since it is not necessary to provide a space for incorporating a separate cushioning material in the housing recess 3 in order to prevent an external impact, it can be formed thin. And since the whole number of parts is small, management aspects, such as inventory management, are simplified.

  In the above example, the container body 1 is made of PET, but other flexible synthetic resins or the like can be used. In particular, if synthetic resin is PET, methacrylic resin (PMMA), acrylonitrile / styrene resin (AS), acrylonitrile / butadiene / styrene resin (ABS), or polypropylene (PP), moldability, durability, and light weight are achieved. This is preferable.

  In the above example, the thicknesses of the container body 1 (the bottom surface 7 and the peripheral wall 6) are both about 1 mm, but can be 0.2 to 3 mm and different thicknesses. If the thickness is too thin, the strength of the container body 1 tends to be impaired. Conversely, if the thickness is too thick, deformation elasticity tends to be difficult. However, the bottom surface 7 is preferably thinner in order to exert a buffering effect due to its bending, and a thickness of 0.2 to 1 mm is suitably used.

  In the above example, the notches 9a and 9b on the bottom surface 7 are formed to have a width of about 0.3 mm. However, from the viewpoint of the strength and appearance of the mold for molding the notches 9a and 9b, any not between 0.3 and 1.0 mm You may make it form in the width | variety.

  In the above example, the gap P [see FIG. 6 (a)] between the suppressing portions 8a and 8b and the bottom surface 7 is set to 0.6 mm, but an arbitrary distance of 0.3 to 0.8 mm is provided. You may do it. If the distance of the gap P is too narrow, there is a tendency that it is difficult to obtain a buffering effect. This is because the inner tray 5 accommodated in the inner wall 5 is too bent and collides with the peripheral wall 6 to cause the cosmetic material to be damaged.

  Next, another embodiment of the cosmetic container of the present invention is shown in FIG. 7 from the back side. In addition, the same code | symbol is attached | subjected to the member same as the said embodiment, and the description is abbreviate | omitted. In this other embodiment, FIGS. 8A and 8B and FIG. 8A are cross-sectional views taken along the line YY of FIG. 8A when FIG. 7 is viewed from the front side direction. As shown in FIG. 9A, which is a ZZ cross-sectional view, and FIG. 9C, which is a plan view of FIG. 8, the bottom surface 7 of the housing recess 3 is formed around the periphery thereof as in the above embodiment. It has notches 9c and 9c ′ along the direction, and is connected to the peripheral wall 6d only at one portion of the cutout portion 7α ″. In addition, the lower part of the center of the peripheral wall 6b on the back side is a notch 6b ′, and in this part, a suppressing portion 7β extending from the bottom surface 7 is provided between the lower end of the peripheral wall 6b and the top surface of the bottom surface 7. It enters with a gap Q of 0.6 mm. In addition, at the lower end of the peripheral wall 6b on the bottom surface 7 side, the restraining portions 8a and 8b that protrude toward the inside of the housing recess 3 are 0.6 mm between the upper surface of the restraining portions 8a and 8b and the bottom surface 7 bottom surface. The gap R is formed. At this time, the thickness of the bottom surface 7 is as thin as about 1 mm, and the notches 9c and 9c ′ are formed with a width of 0.3 mm.

  According to this configuration, the container main body 1 is formed of flexible PET, and is cut at two locations across the opposing portion of the peripheral edge of the bottom surface 7 (the portion in contact with the peripheral wall 6a and 6c opposite thereto). Since the notch and the notch at the lower end of the peripheral wall 6b are a continuous long notch, the bottom surface 7 has a so-called cantilever structure. When an impact or the like is applied to the container body 1, a notch 9c on the bottom surface 7 is formed. , 9c ′ is connected to the peripheral wall 6 in a state where the inner plate 5 is placed and held on the inner plate 5 (a state where the inner plate 5 is fixed to the bottom surface 7 with a hot melt adhesive) 7α ″. It can be bent up and down and left and right around this part to absorb the impact. Further, since the bottom surface 7 is formed to be thin with a thickness of about 1 mm, the bottom surface 7 is more easily bent and can further absorb an impact or the like when dropped.

  Then, a notch 6b ′ portion is provided at the center lower portion of the peripheral wall 6b on the back side, and a suppression portion 7β extending from the bottom surface 7 is inserted into this portion, and between these (the lower surface of the peripheral wall 6b and the upper surface of the suppression portion 7β of the bottom surface 7) Is provided with a gap Q of 0.6 mm, so that even if the inner portion of the bottom surface 7 is greatly bent upward from the notch forming portion, the restraining portion 7β hits the lower end of the peripheral wall 6b and is bent. Since the deformation is suppressed, the bending of the bottom surface 7 can be more reliably kept within a certain range, and the cosmetic material can be prevented from being damaged due to excessive bending. Further, at the lower end of the peripheral wall 6b on the bottom surface 7 side, there are provided restraining portions 8a and 8b that protrude inside the housing recess 3, and a gap R of 0.6 mm is provided between the bottom surface of the bottom surface 7 and the top surfaces of the restraining portions 8a and 8b. Therefore, even if the inner portion of the bottom surface 7 is greatly bent downward from the notch forming portion, the bending deformation of the bottom surface 7 is suppressed by hitting the suppressing portions 8a and 8b. Therefore, the cosmetic can be prevented from being damaged by excessive bending. Furthermore, unlike the conventional cosmetic container, it is not necessary to use a cushioning material as a separate part, and the cushioning material is formed so as to be integrated, so that it can be easily produced at low cost. Further, since it is not necessary to provide a space for incorporating a separate cushioning material in the housing recess 3 in order to prevent an external impact, it can be formed thin. And since the whole number of parts is small, management aspects, such as inventory management, are simplified.

  Furthermore, FIG. 12 shows still another embodiment of the cosmetic container of the present invention. In addition, the same code | symbol is attached | subjected to the member same as the said embodiment, and the description is abbreviate | omitted. In this further embodiment, FIGS. 10 and 12 showing the state in which the inner tray 5 is placed are viewed from the rear side, FIG. 11 is a partially enlarged explanatory view of FIG. As shown in FIG. 14 (a) which is a W cross-sectional view, FIG. 14 (b) which is a VV cross-sectional view of FIG. 12, and FIG. 14 (c) which is a plan view of FIG. 7 and the peripheral wall 6 are formed in a substantially square dish shape. The bottom surface 7 has a notch 9d extending along the periphery at a position slightly inward from the periphery of each corner of the four corners, and is connected to each peripheral wall 6 at the center portion 7γ of each of the four sides. ing. At this time, the thickness of the bottom surface 7 is as thin as 1 mm, and the notch 9d is formed with a width of 0.5 mm.

  According to this configuration, the container body 1 is formed of flexible PET, and the notches 9d are formed on the peripheral edges of the corners of the bottom surface 7 so as to face each other. When an impact or the like is applied, the portion inside the notch 9d of the bottom surface 7 is bent up and down and left and right with the inner plate 5 placed on the 7γ portion as an axis to absorb the impact or the like. Can do. And since the bottom face 7 is connected to each peripheral wall 6 at a 7γ portion in a balanced manner, the strength of the entire container is increased. Further, since the 7γ portions of the bottom surface 7 are formed to be distributed on the respective peripheral walls 6, the deformation of the inner portion from the notch forming portion of the bottom surface 7 is within a certain range, and the cosmetic is damaged due to excessive bending. Can be effectively prevented. Furthermore, since the shape of the container body 1 is simple, the mold for manufacturing the container body 1 can be simplified, and the manufacturing process can be simplified and the time can be saved. Further, since the bottom surface 7 is formed as thin as 1 mm, the bottom surface 7 is more easily bent and can absorb more impacts such as when dropped. And it is not necessary to use a shock absorbing material as a separate part unlike the cosmetic container of a prior art example, and since the shock absorbing material is formed integrally, it can be manufactured simply and at low cost. Further, since it is not necessary to provide a space for incorporating a separate cushioning material in the housing recess 3 in order to prevent an external impact, it can be formed thin. Furthermore, since the total number of parts is small, management aspects such as inventory management are simplified.

  In this embodiment, the peripheral wall 6 of the housing recess 3 is not provided with a suppressing portion that directly suppresses bending of the inner portion from the notch forming portion of the bottom surface 7, as shown in FIG. Since the bottom surface of the inner tray 5 abuts against the restraining portion 8c using the edge 9d of the peripheral edge of the bottom surface 7 and its movement is restricted, the inner portion of the bottom surface 7 is indirectly more than the notch forming portion. Bending is suppressed.

  In the present invention, when the inner dish filled with the cosmetic is not integrally fixed to the bottom surface of the container recess with hot melt or the like, for example, the resin inner dish and the peripheral wall of the container recess are uneven. In the case of fixing the inner tray to the receiving recess by fitting the irregularities to each other, the degree of freedom in the receiving recess of the inner tray is large. For the purpose of preventing excessive movement in the upward direction, the stopper 10 is provided at the upper end of the peripheral wall 6 at the four positions of the opening of the housing recess 3 as shown in FIGS. 16 (a) and 16 (b). Is preferred. Thereby, since the movement of the inner plate 5 due to the bending of the bottom surface 7 inside the notch 9d and the movement of the inner plate 5 itself can be stored within a certain range, the inner plate 5 is placed on the bottom surface of the housing recess 3. Even when it is not integrally bonded and fixed, damage to the cosmetic can be effectively prevented.

  Furthermore, the shape of the cosmetic container that can be used in the present invention is not limited to a substantially square shape as shown in FIGS. 2, 7, and 12, but various shapes such as a substantially circular shape, a substantially elliptical shape, and a substantially trapezoidal shape. be able to.

  The present invention relates to a cosmetic container that can absorb external impacts and the like, has a small number of parts, and can be downsized.
