Description

  The present invention relates to a cosmetic container such as a compact case.

  Conventionally, various cosmetic containers such as a compact case have been used as a cosmetic container that accommodates and carries a middle dish (refill container) filled with a solid cosmetic such as a foundation or eye shadow. If these cosmetic containers are dropped on the floor or the like, the solid cosmetics in the inner plate are cracked or damaged by the impact at the time of dropping. Many cushioning members are arranged between the dish receiving recess and the above-described middle dish, and this shock absorbing member absorbs and relieves impacts when dropped (see, for example, Patent Documents 1 and 2). .)

  In addition, in the Japanese Patent Application No. 2008-216768, the applicant is also provided with an inner dish 12 filled with the cosmetic 10 and an inner dish accommodating recess 11a for accommodating the inner dish 12, as shown in FIG. In the cosmetic container including the container body 11 and the lid body 13 that covers the container body 11, a convex shape is applied between the bottom surface of the bottom plate 12a of the intermediate dish 12 and the bottom surface of the intermediate dish accommodating recess 11a. Even if the container main body 11 receives an impact when the cosmetic container is dropped by interposing the substantially cushion-shaped flexible cushioning material 15 having a plurality of shaped air cushion portions (hollow convex portions 15b), the above-mentioned Proposing a cosmetic container capable of absorbing the impact load quickly by deforming each hollow convex portion 15b of the sheet-like flexible cushioning material 15 and mitigating the transfer of the impact to the inner tray 12 Yes.

  The flexible cushioning material 15 used in this cosmetic container is flat as a whole as shown in FIG. 6A, which is a plan view of FIG. 6A and a YY ′ sectional view thereof. It is formed by forming a large number of shallow hollow convex portions 15 b that are circular in a plan view and floated in a cross-section arc shape on a substantially sheet-like base material using a press working device or the like.

  Moreover, the part (flat part 15a) which is not lifted other than the said hollow convex part 15b among the lower surfaces (the container main body 11 side) of the said flexible shock absorbing material 15 is applied to the bottom face of the said intermediate dish accommodation recessed part 11a. It is bonded and fixed by a hot melt adhesive or the like (not shown). Then, the upper surface of the flexible cushioning material 15 (inner dish 12 side) is coated with the same hot melt adhesive applied to the top of each of the hollow protrusions 15b as above. ) It is bonded to the bottom surface of 12 in a dot shape, and the inner tray 12 is elastically supported.

  In addition, the flexible cushioning material 15 is opposite to the front and back, that is, the portion that is not lifted (flat portion 15a) is on the upper side (inner tray 12 side), and the top of each hollow convex portion 15b is on the lower side (container body 11). In some cases.

  By the way, the cosmetic container (see FIG. 5) proposed by the present applicant as described above is disposed between the sheet-like flexible cushioning material 15 and the inner tray 12 (inverted as described above). In this case, since the sheet-like flexible cushioning material 15 and the middle dish receiving recess 11a are in a so-called “spotted” state with a small adhesion area, There is a possibility that the fixing of the plate (gold plate) 12 may be loosened, and an improvement thereof is desired.

  The present invention has been made in view of such circumstances, and prevents cracking due to a drop impact or the like of the cosmetic filled in the inner dish, and firmly bonds and fixes the inner dish in the inner dish accommodating recess. The purpose is to provide a cosmetic container that can be used.

In order to achieve the above object, the cosmetic container of the present invention is formed with an inner dish in which cosmetics are filled in a recess made of a bottom plate and a peripheral side wall, and an inner dish accommodating recess for accommodating the inner dish. A container main body and a lid for covering the container main body, and a plurality of hollow protrusions are formed along the bottom surface of the middle dish receiving recess of the container main body so as to create a gap between the bottom surface and the bottom plate of the middle dish. A cosmetic sheet container in which a substantially sheet-like flexible cushioning material with a shaped portion is attached, and the middle dish is housed and held in the middle dish housing recess through the flexible cushioning material The flexible cushioning material is shaped so as to protrude toward the bottom plate of the intermediate plate from the lower flat portion for bonding and fixing, which is in contact with the bottom surface of the intermediate dish receiving recess. is a body-side contact part consisting of an upward hollow projecting portions, the upper adhesive fixing in contact with the bottom plate in said dish Rights Part this and the upper flat portion of downwardly hollow protrusions in comprising a dish-side abutment portion which is shaped so as to protrude toward the bottom surface in said tray accommodating recess is formed, the bottom plate and the friendly in said dish The cosmetic container in which the space between the upper flat portion of the flexible cushioning material and the lower flat portion of the flexible cushioning material and the bottom surface of the middle dish accommodating recess is bonded and fixed is the first. The gist.

The present invention, among them, the gold plates is used as the dishes in the above, between the bottom plate and the upper flat portion of the flexible cushioning material of the gold dishes, and, below said flexible buffer material between the bottom side flat portion and the in the dish accommodating recess are respectively bonded using double-sided adhesive tape, in the interior of the respective hollow protrusions, sealed cavity is in so that formed respectively makeup The material container is the second gist.

  In the present invention, a sheet-like flexible cushioning material having a hollow convex portion that can effectively absorb an impact load by an air cushion action in which an internal cavity (concave space) is crushed is filled with a solid cosmetic. In the cosmetic container disposed between the middle dish and the middle dish housing recess, flat portions for increasing the contact area between these members are provided on both surfaces of the sheet-like flexible cushioning material. To achieve the intended purpose.

  That is, the cosmetic container of the present invention has a main body side contact portion formed with an upward (front-facing) hollow convex portion and a middle dish side contact portion formed with a downward (backward) hollow convex portion. Since the sheet-like flexible cushioning material is disposed between the middle dish receiving recess and the middle dish of the container body, when the container body receives an impact from the vertical direction when the cosmetic container is dropped, By deforming the hollow protrusions so as to crush the internal cavities (concave spaces), the impact load is quickly absorbed. Accordingly, the cosmetic container according to the present invention, like the cosmetic container previously proposed by the present applicant, is difficult to transmit an external impact to the inner dish, and cracks of the solid cosmetic filled in the inner dish, etc. Can be effectively prevented.

In addition, since the flexible cushioning material is provided with a lower flat part in contact with the bottom surface of the inner dish receiving recess and an upper flat part in contact with the bottom plate of the inner dish, either one side is provided. Compared with a conventional flexible cushioning material provided with a flat portion only, the contact area with the other member increases. Therefore, the cosmetic container according to the present invention can stably hold the inner dish in the inner dish accommodating recess without reducing the shock absorbing power during the dropping or the like.

Further, in the present invention, among them, a metal pan is used as the intermediate plate, and between the bottom plate of the metal plate and the upper flat portion of the intermediate plate side contact portion, and of the main body side contact portion. between the lower flat section and the in the dish accommodating recess bottom, are respectively bonded using double-sided adhesive tape, in the interior of the respective hollow protrusions, which sealed cavity is in so that formed respectively Compared to a conventional flexible cushioning material in which a flat portion is provided only on one side, the area contributing to the adhesion of the other side member is increased. Therefore, the cosmetic container of the present invention can usually easily hold and hold the metal plate that is often adhesively fixed in the middle plate housing recess, and even when subjected to a large impact or the like, It is possible to prevent the metal plate from coming off or jumping out of the intermediate plate housing recess without loosening the adhesive fixing of the metal plate.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to this embodiment.

  FIG. 1 is a perspective view for explaining the structure of a cosmetic container according to an embodiment of the present invention. FIG. 2 (a) is a plan view of a flexible cushioning material used in the cosmetic container. b) is an XX ′ cross-sectional view of the flexible cushioning material. FIG. 1 shows a state (indicated by a two-dot chain line) in which the intermediate plate 2 is taken out in order to make the flexible cushioning material 5 between the intermediate plate 2 and the intermediate plate accommodating recess 1a easily visible. Yes. In the figure, reference numeral 4 denotes a mirror attached to the lid 3, and 1b denotes a recess for storing a cosmetic tool.

  The cosmetic container in the present embodiment is a compact case for accommodating and carrying a metal inner dish (gold plate) 2 filled with a solid cosmetic (10) such as a foundation or eye shadow. 2 is provided with a container body 1 having a middle dish housing recess 1a for housing 2 and a lid 3 for covering the container body 1, and the bottom surface of the middle dish housing recess 1a (the middle dish 2 and the middle dish housing recess 1a). 1), a sheet-like flexible cushioning material 5 is provided as an impact absorbing member as shown in FIG. 1, and the inner tray 2 and the flexible cushioning material are provided by a double-sided adhesive tape (not shown). 5 and between the flexible cushioning material 5 and the intermediate dish housing recess 1a.

  The flexible cushioning material 5 is formed using a flexible material, for example, a material having elasticity such as resin or latex, and a substantially flat sheet-like base material using a press working device or the like. By applying heat and pressure, a large number of hollow convex portions (5b, 5d) having a circular shape in plan view and having small cavities (concave spaces) formed therein are formed.

  However, in this embodiment, the shape of the sheet-like flexible cushioning material 5 in which the hollow convex portions (5b, 5d) are shaped is the peripheral portion (FIGS. 2A and 2B). There is a slight difference between the two areas A) and the central part (B). That is, the peripheral portion has a lower flat portion 5a formed flat so as to secure a contact area with the bottom surface of the inner dish accommodating recess 1a, and a plurality of hollows projecting upward (upward) from the lower flat portion 5a. It is comprised from convex part 5b, 5b, ..., and when it arrange | positions in the inside tray accommodation recessed part 1a of cosmetics containers, and is fixed with the said double-sided adhesive tape, of this flexible buffer material 5 It functions as a “main body contact portion” A that improves the adhesive strength to the container main body 1.

  Further, the central portion of the sheet-like flexible cushioning material 5 has an upper flat portion 5c formed flat so as to secure a contact area with the bottom surface of the inner dish 2, and downward (backward) from the upper flat portion 5c. Are formed from a plurality of hollow convex portions 5d, 5d,..., And the inner tray 2 is housed in the inner tray housing concave portion 1a and bonded and fixed with the double-sided adhesive tape. The flexible buffer material 5 functions as an “inner tray side abutting portion” B that improves the adhesive strength to the inner tray 2.

  In addition, it is important that the flexible cushioning material 5 in the present embodiment has a certain elasticity and a flexibility that easily deforms against an impact. For that purpose, the hardness (Shore A hardness) The angle is preferably 5 to 70 °, and particularly preferably set within the range of 10 to 60 °. And the thickness of the sheet | seat part of the said flexible buffer material 5 is preferably set in the range of 0.25-2.0 mm, and the height (nothing) including the hollow convex parts 5b and 5d which protruded. The height in the state of load is preferably set within a range of 1.5 to 3.0 mm. Examples of the material constituting the flexible buffer material 5 include flexible materials such as various types of rubber such as silicone rubber, ethylene-propylene copolymer rubber (EPDM), urethane rubber, and silicone resin. Various synthetic resin materials and various elastomer materials are used.

  According to said structure, even if a cosmetics container receives the impact from the outside, for example, the impact at the time of dropping, etc., the impact is directly transmitted from the bottom part of the container main body 1 to the inner plate (metal plate) 2. There is nothing. That is, since the hollows (concave spaces) formed inside the hollow convex portions 5b and 5d of the flexible cushioning material 5 are easily deformed, even when an impact is received, the impact is quickly absorbed by the deformation.・ Relieved. Therefore, it is difficult for the impact to be transmitted to the inner tray 2, and an excellent buffering effect can be achieved. In addition, the hollow protrusions 5b and 5d themselves have a large amount of deflection due to the cavities, and in this respect, the buffering effect is also excellent.

  Moreover, the main body side contact portion (peripheral portion) and the middle dish side contact portion (center portion) of the flexible cushioning material 5 include a lower flat portion 5a that is in contact with the bottom surface of the middle dish housing recess 1a, Since the upper flat part 5c in contact with the bottom plate of the dish 2 is provided, the intermediate dish 2 is supported in a balanced manner as compared with the conventional flexible cushioning material in which the flat part is provided only on one side. can do. Therefore, the cosmetic container according to the present embodiment can stably hold the inner dish 2 in the inner dish accommodating recess 1a without lowering the impact absorbing power at the time of dropping or the like.

  In the cosmetic container, the inner plate 2 is a gold plate, and even when these members are bonded using the double-sided adhesive tape, adhesive, or the like, the adhesive strength is improved and fixed firmly and securely. It becomes possible. Therefore, the cosmetic container according to the present embodiment is less likely to loosen the fixing of the inner dish 2 even when subjected to a large impact or the like.

  Furthermore, the flexible cushioning material 5 as a whole has a substantially sheet shape, and the hollow convex portions 5b and 5d can be integrally formed by press molding or die molding. Therefore, not only is it easy to manufacture, but this can be easily and stably fixed to the bottom surface of the dish receiving recess 1a in the cosmetic container using the double-sided adhesive tape, adhesive, etc. It has the advantage of high production efficiency.

  In the above-described embodiment, an example in which the shallow hollow convex portions 5b and 5d that are circular in plan view and floated in a circular arc shape are formed (shaped) on the flexible cushioning material 5 is shown. The shape of each convex portion of the cushioning material 5 is not limited to the above example, as long as it is a shape that creates a partial gap (cavity) between the bottom surface of the middle dish containing concave portion 1a or the bottom plate of the middle dish 2, Any shape is acceptable. For example, the cross-sectional shape is a trapezoidal shape (see FIG. 3A), a square shape (see FIG. 3B), a triangular cone shape, a square cone shape, or the like, or a shape with a hole at the top. (See FIG. 3C). Furthermore, it is not necessary that the hollow convex portions 5b and 5d are formed in a large number of distributions. For example, the convex strips having various cross-sectional shapes may have shapes that extend in an appropriate arrangement in the surface direction. .

  The flexible cushioning material of the main body side contact portion A composed of the lower flat portion 5a and the hollow convex portion 5b and the middle dish side contact portion B composed of the upper flat portion 5c and the hollow convex portion 5d. Arrangements and sections (regions) on 5 can be freely distributed within the flexible cushioning material 5. For example, as shown in FIG. 4A, the middle dish side contact portion B (shaded portion) is annularly arranged, or as shown in FIG. 4B, the middle dish side contact portion B (shaded portion) is arranged. It may be divided into several parts and arranged so as to be evenly distributed on the surface to protect the corners of the inner plate (metal plate) 2 that is considered to be most strongly affected by external impacts. .

  In addition, when bonding between the flexible cushioning material 5 and the bottom of the middle dish housing recess 1a and between the flexible cushioning material 5 and the bottom surface of the middle dish 2, In addition to using a double-sided adhesive tape as in the examples, a hot melt adhesive, a UV curable adhesive, or the like can also be used. Note that the adhesive material for bonding the flexible cushioning material 5 and the bottom surface of the middle dish receiving recess 1a and the adhesive material for bonding the flexible cushioning material 5 and the lower surface of the middle dish 2 need not necessarily be the same. For example, one side can be bonded with a double-sided adhesive tape, and the other side can be bonded with a hot melt adhesive.

  Furthermore, although the said embodiment uses the metal plate as the inner plate 2, it cannot be overemphasized that this invention can be applied also when using a resin plate as an inner plate.

  The cosmetic container of the present invention is suitable for a cosmetic container such as a foundation or a compact case for eye shadow, in which the solid cosmetic filled in the inner dish is liable to break due to impact such as dropping. In particular, it is suitable for a cosmetic container in which a metal middle dish is accommodated and fixed in a middle dish accommodating recess.
