Description

  The present invention relates to a cosmetic container and a method for producing the same.

Conventionally, in various cosmetic containers such as refill containers that contain solid cosmetics such as eye shadows, cheek colors, foundations, etc., if they are dropped on the floor, the impact at the time of dropping is a cosmetic container. In order to act on the solid cosmetic contained in the container and the solid cosmetic is cracked or damaged, an elastic member or the like is provided between the container body of the cosmetic container and the inner dish containing the solid cosmetic, Many of these elastic members and the like are designed to improve the drop strength by reducing the impact at the time of dropping. As such a cosmetic container, a cosmetic compact shown in FIG. 20 has been proposed. This cosmetic compact includes a body 31, a lid 32 pivotally attached to the rear part of the body 31, and a drum 33 containing a solid cosmetic 34. A double-sided adhesive tape 36 is attached to the bottom 31a of the body 31. A cushioning material sheet 35 such as urethane foam is fixed via a pad, and the drum 33 is placed and fixed on the cushioning material sheet 35 via a double-sided adhesive tape 37 (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 61-12886

  However, in the above-described cosmetic compact, since urethane foam or the like is used as the cushioning material sheet 35, the pouch is made to slide into the solid cosmetic 34 accommodated in the drum 33, for example, during use. If the transfer is repeated, the cushioning material sheet 35 on the lower side of the drum 33 is repeatedly pressed to expand and contract up and down, and the cushioning material sheet 35 deteriorates early due to repeated expansion and contraction, and the cushioning material sheet. There exists a problem that the elasticity of 35 falls. Moreover, when the cushioning sheet 35 is bonded and fixed to the body 31, the double-sided adhesive tape 36 is first moved to a predetermined position (scheduled adhesion position) on the bottom 31a of the body 31 and then pressed to the body 31 side. Then, the buffer sheet 35 is moved to a predetermined position (scheduled adhesion position) of the double-sided adhesive tape 36 and positioned, and then pressed and pressed to the double-sided adhesive tape 36 side. This requires a long time for these operations, resulting in poor work efficiency and increased costs. In addition to the body 31 and the lid 32, the cushioning material sheet 35 and the double-sided adhesive tape 36 for bonding and fixing the sheet to the bottom 31a of the body 31 are required, which increases the number of parts and makes it difficult to manage inventory management and the like.

  The present invention has been made in view of such circumstances, and the elasticity does not decrease over a long period of time. Moreover, the work efficiency is good, the cost is reduced, and the number of parts is small and management such as inventory management is performed. The purpose is to provide an easy-to-use cosmetic container and its production method.

  In order to achieve the above object, the present invention comprises a container main body having an upper dish receiving recess formed on the upper surface, a lid for covering the container main body, and a middle dish for storing cosmetics, and the container main body. An elastic layer made of an ultraviolet curable adhesive, which is cured by ultraviolet irradiation, is provided on the bottom surface of the inner dish housing recess, and the cosmetic container in which the inner dish is placed and supported by the elastic layer is a first container. And a container body having an upper dish receiving recess formed on the upper surface, a lid for covering the container body, and a middle dish for storing cosmetics, A cosmetic container in which an elastic layer made of an ultraviolet curable adhesive cured by ultraviolet irradiation is provided, and an inner dish is placed and supported on the elastic layer is a second gist, and the inner dish on the upper surface A container body with a housing recess, a lid that covers the container body, and cosmetics And an elastic layer made of an ultraviolet curable adhesive that is cured by ultraviolet irradiation is provided on the bottom surface of the intermediate dish housing recess of the container body, and at least one of the bottom surface of the intermediate dish is provided on the elastic layer. A cosmetic container having a portion bonded and fixed thereto, a container main body having an upper dish receiving recess formed on the upper surface, a lid for covering the container main body, and a middle dish for storing the cosmetic An elastic layer made of an ultraviolet curable adhesive that is cured by ultraviolet irradiation is provided on the side surface of the container tray recess of the container body, and at least a part of the side surface of the tray is bonded and fixed to the elastic layer. The cosmetic container is a fourth gist, and an application step of applying a liquid UV-curable adhesive to the bottom surface of the inner dish-receiving recess formed on the upper surface of the container body, and an ultraviolet ray applied after this application step Curing by curing the curable adhesive with UV irradiation An elastic layer forming step for forming a layer, an accommodating step for accommodating an intermediate plate for accommodating cosmetics in the middle dish accommodating recess of the container body after the elastic layer forming step, and placing the elastic plate on the elastic layer; The manufacturing method of the cosmetic container provided with the lid closing step of closing the container body with a lid after the housing process is a fifth gist, and the liquid is formed on the side surface of the inner dish housing recess formed on the upper surface of the container body. An application process for applying an ultraviolet curable adhesive, an elastic layer forming process for forming an elastic layer by irradiating the applied ultraviolet curable adhesive with ultraviolet irradiation after the application process, and an elastic layer forming process. An accommodating step of accommodating an intermediate dish for accommodating cosmetics and placing it on the elastic layer in the intermediate tray accommodating recess of the container main body, and a closing step of covering the container main body with a lid after the accommodating step As a sixth gist of a method for producing a cosmetic container comprising A fixing step of fixing the intermediate plate for storing cosmetics in the intermediate plate receiving recess in a state where the container main body in which the upper plate receiving concave portion is formed is directed upward or downward, and after the fixing step, the container main body With the liquid crystal facing downward, an injection step of injecting a liquid UV-curable adhesive from an injection hole formed in the bottom wall of the container body and adhering it to at least a part of the bottom surface of the intermediate dish, and An elastic layer forming step of forming an elastic layer by curing the injected ultraviolet curable adhesive by irradiating with ultraviolet rays, and a lid closing step of covering the container body with a lid after the elastic layer forming step.

An eighth aspect of the present invention is a cosmetic container manufacturing method including a layer forming step and a lid closing step of covering the container body with a lid after the elastic layer forming step.

  That is, in the first and second cosmetic containers of the present invention, when the ultraviolet curable adhesive is cured by ultraviolet irradiation, the cured product becomes an elastic body, and on the surface other than the adhesive surface to other objects, It utilizes physical properties that have no adhesive force and are resistant to repeated external loads and can maintain the same elasticity for a long time. Accordingly, as in the first cosmetic container of the present invention, when an elastic layer made of an ultraviolet curable adhesive formed by curing with ultraviolet irradiation is provided on the bottom surface of the container tray recess in the container body, Even if it is to repeatedly press the surface of the elastic layer (inner dish placement surface) with the inner dish by sliding the puff over the cosmetic contained in the inner dish and transferring the cosmetic to the puff, By repeating this pressing, the elastic layer is not deteriorated at an early stage and the elasticity is not lowered, and good elasticity can be maintained for a long time. In addition, when an elastic layer is provided on the bottom surface of the container tray receiving recess in the container body, it is only necessary to apply an ultraviolet curable adhesive to the bottom surface of the container tray recess in the container body and then irradiate with ultraviolet rays. The work can be performed in a short time, the work efficiency is good, and the cost is reduced. In addition, since the elastic layer is directly bonded and fixed to the bottom surface of the container tray receiving recess by the ultraviolet irradiation, the cushioning material sheet 35 is bonded to the bottom 31a of the body 31, which is necessary in the conventional example. The double-sided adhesive tape 36 to be fixed can be dispensed with, the number of parts is reduced, and management aspects such as inventory management are simplified. Moreover, according to the manufacturing method of the 1st cosmetics container of this invention, the 1st cosmetics container which show | plays the said outstanding effect can be manufactured. In the present invention, the “elastic layer” means a layer having a Shore A hardness of 10 to 40.

  In addition, when an elastic layer made of an ultraviolet curable adhesive that is cured by ultraviolet irradiation is provided on the side surface of the container tray recess in the container body as in the second cosmetic container of the present invention, For example, by repeatedly sliding the puff on the cosmetic contained in the inner dish and transferring the cosmetic to the puff, the surface of the elastic layer (the inner dish mounting surface) is repeatedly pressed by the inner dish. However, the elastic layer is not deteriorated at an early stage by repeating this pressing, and the elasticity is not lowered, and good elasticity can be maintained for a long period of time. In addition, when an elastic layer is provided on the side surface of the container tray receiving recess in the container body, it is only necessary to irradiate with ultraviolet rays after applying an ultraviolet curable adhesive to the side surface of the container tray recess in the container body. The work can be performed in a short time, the work efficiency is good, and the cost is reduced. Moreover, since the elastic layer is directly bonded and fixed to the side surface of the container tray receiving recess by the ultraviolet irradiation, the cushioning material sheet 35 is bonded to the bottom 31a of the body 31, which was necessary in the conventional example. The double-sided adhesive tape 36 to be fixed can be dispensed with, the number of parts is reduced, and management aspects such as inventory management are simplified. Furthermore, since an elastic layer is provided on the side surface of the container tray receiving recess of the container body, and the intermediate dish is placed on this elastic layer, a gap may be provided between the bottom surface of the container receiving recess and the intermediate dish. For example, even if the cosmetic container is dropped on the floor or the like and the bottom wall of the cosmetic container collides with the floor surface, the impact at the time of collision does not directly act on the inner dish from the bottom wall, and the buffering effect is excellent. . Moreover, according to the manufacturing method of the 2nd cosmetics container of this invention, the 2nd cosmetics container which show | plays the said outstanding effect can be manufactured.

  In the first cosmetic container according to the present invention, after the elastic layer has applied a liquid UV-curable adhesive to the bottom surface of the container tray housing recess of the container body, In the case of being cured by irradiation, the UV curable adhesive can be easily applied to the bottom surface in a very short time, and the working efficiency is greatly improved.

  In the second cosmetic container according to the present invention, after the elastic layer has applied a liquid UV-curable adhesive to the side surface of the container tray recess in the container body, the applied UV-curable adhesive is applied to the ultraviolet ray. In the case of being cured by irradiation, the UV curable adhesive can be easily applied to the side surface in a very short time, and the working efficiency is greatly improved.

  Similarly to the first and second cosmetic containers of the present invention, when the third and fourth cosmetic containers of the present invention are cured by ultraviolet irradiation, the cured product is elastic. In addition to being in the body, the part that was in contact (or bonded) with another object before curing adheres to the other object, but the part that was not in contact with other object before curing has no adhesive force and is repeated It utilizes the physical properties of being resistant to external loads and capable of maintaining the same elasticity for a long time. Therefore, as in the third cosmetic container of the present invention, for example, a liquid is formed between the bottom surface of the container tray recess in the container body and at least a part of the bottom surface of the tray fixed to the recess tray recess. In addition, the ultraviolet curable adhesive is interposed, and the ultraviolet curable adhesive is irradiated with ultraviolet rays in a state where the bottom surface of the above-described dish receiving recess and at least a part of the bottom surface of the intermediate dish are in contact (or bonded) with each other. Then, an elastic layer made of an ultraviolet curable adhesive that is cured by ultraviolet irradiation is provided on the bottom surface of the above-described dish receiving recess, and at least a part of the bottom surface of the dish is bonded to this elastic layer. Even if it is fixed, the same actions and effects as the first cosmetic container can be obtained. Moreover, according to the manufacturing method of the 3rd cosmetics container of this invention, the 3rd cosmetics container which show | plays the said outstanding effect can be manufactured.

  In the third cosmetic container of the present invention, the elastic layer is liquid from an injection hole formed in the bottom wall of the container body with the container body having the middle dish fixed to the middle dish housing recess facing downward. In the case where the injected ultraviolet curable adhesive is cured by irradiating with ultraviolet rays after injecting the ultraviolet curable adhesive and adhering to at least a part of the bottom surface of the inner dish. The UV curable adhesive can be easily injected into the portion between the bottom wall of the tray and the bottom surface of the inner tray in a very short time, and the working efficiency is greatly improved.

  Moreover, like the 4th cosmetics container of this invention, it is liquid between the side surface of the middle tray accommodation recessed part of a container main body, and at least one part of the side surface of the middle dish fixed to this middle dish accommodation recessed part, for example. In addition, the ultraviolet curable adhesive is interposed, and the ultraviolet curable adhesive is irradiated with ultraviolet rays in a state where the side surface of the concave portion accommodating recess and at least a part of the side surface of the intermediate tray are in contact (or bonded) with each other. Then, an elastic layer made of an ultraviolet curable adhesive that is cured by ultraviolet irradiation is provided on the side surface of the inner dish housing recess, and at least a part of the side surface of the inner dish is bonded to the elastic layer. Even when it is fixed, the same operation and effect as the second cosmetic container are obtained. Moreover, according to the manufacturing method of the 4th cosmetics container of this invention, the 4th cosmetics container which show | plays the said outstanding effect can be manufactured.

  In the fourth cosmetic container of the present invention, the elastic layer is a liquid ultraviolet curable liquid from an injection hole formed in the side wall of the container body in a state where the middle dish is fixed to the container dish receiving recess of the container body. After the adhesive is injected and adhered to at least a part of the side surface of the middle dish, the injected UV curable adhesive is cured by irradiating with ultraviolet rays. Injection of the UV curable adhesive into the portion between the sides of the dish can be easily performed in a very short time, and the working efficiency is greatly improved.

  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 shows an embodiment of a first cosmetic container according to the present invention. In the figure, reference numeral 1 denotes a synthetic resin container body having an upper dish receiving recess 1a formed on the upper surface thereof, and 2 denotes a synthetic resin lid body that covers the upper surface of the container main body 1. A rear end portion of the lid body 2 is rotatably connected to the end portion by a connecting pin 3. 4 is a metal or synthetic resin intermediate dish filled with a solid cosmetic material 5 such as a foundation, and is detachably accommodated and fixed in the intermediate dish accommodating recess 1a of the container body 1. In the figure, 1b is a recess formed on the upper surface of the front end portion of the container body 1, and 1c is an engaging protrusion projecting from the back surface of the recess 1b, protruding from the front end of the lid 2. The engagement claw portion 2a is detachably engaged.

  As shown in FIG. 2, the container main body 1 has elastic layers 11 formed by curing an ultraviolet curable silicone adhesive by ultraviolet irradiation at the front, rear, left and right corners of the bottom surface 7 of the dish receiving recess 1a. It is bonded and fixed, and supports the inner tray 4 (four corners, front, rear, left and right) (see FIG. 1) placed on the upper surface thereof. In addition, an adhesive layer 12 made of a hot melt adhesive is formed at the center of the bottom surface 7 of the above-mentioned inner dish accommodating recess 1a, and the bottom surface of the inner dish 4 is detachably bonded to the upper surface of this adhesive layer 12. , It is fixed.

  The cosmetic container can be produced as follows. That is, first, a coating device containing a liquid ultraviolet curable silicone adhesive in its own tank and an ultraviolet irradiation device (both not shown) are prepared, and then the middle dish of the container body 1 in an open state. A liquid UV curable silicone adhesive (contained in a tank) is applied to the four corners of the bottom surface 7 of the housing recess 1a from the nozzle of the coating device to form a coating film having a thickness of 2 mm (coating step). Then, the applied UV curable silicone adhesives at the four corners are formed on the elastic layer 11 by being irradiated with UV rays from the mercury lamp of the UV irradiation device or the like to be cured (elastic layer forming step). The intermediate dish 4 filled with the cosmetic 5 is accommodated in the intermediate dish accommodating recess 1a of the container body 1 and placed on the elastic layer 11 (accommodating step), and then the upper surface opening of the container body 1 is covered with the lid. Close with 2 (Capping process) In addition, you may perform the said application | coating using the dispenser which accommodated the liquid ultraviolet curing silicone adhesive. In addition, after the coating process, the elastic layer forming process, and the housing process are performed without attaching the lid body 2 to the container body 1, the lid body 2 is connected to the container body 1 and closed in the lid closing process. It may be covered. In this embodiment, ultraviolet irradiation was performed for 5 seconds to form the elastic layer 11 having a thickness of 2 mm. The elastic layer 11 had a hardness (Shore A hardness) of 30.

  As described above, the ultraviolet curable silicone adhesive becomes an elastic body based on the properties of the silicone cured body by curing by ultraviolet irradiation, and the elastic layer 11 is formed. The elastic layer 11 itself has elasticity, but the upper surface and the peripheral side surface (the surface that is not in contact with the bottom surface 7 of the inner dish accommodating recess 1a) have no adhesive force. Even if the middle dish 4 is placed on the elastic layer 11, the middle dish 4 does not adhere to the elastic layer 11. In addition, due to the nature of the ultraviolet curable silicone adhesive, the same elasticity can be maintained over a long period of time even when a repeated external load acts on the upper surface of the elastic layer 11 in the vertical direction. In addition, since the lower surface of the elastic layer 11 (the surface in contact with the bottom surface 7 of the intermediate dish accommodating recess 1a) is adhered to the bottom surface 7 of the intermediate dish accommodating recess 1a, the elastic layer 11 is the intermediate dish. It does not peel from the housing recess 1a.

  As described above, in this embodiment, the elastic layer 11 is formed by curing an ultraviolet curable silicone adhesive by irradiation with ultraviolet rays. Therefore, at the time of use, the elastic layer 11 is applied to, for example, the solid cosmetic 5 contained in the inner dish 4. Even if the puff is slid and the solid cosmetic 5 is transferred to the puff repeatedly, the upper surface of the elastic layer 11 (the inner dish mounting surface) is repeatedly pressed in the vertical direction, and it is good for a long time. Elasticity can be maintained. In addition, in the case where the elastic layer 11 is provided on the bottom surface 7 of the middle dish receiving recess 1a of the container body 1, if an ultraviolet curable silicone adhesive is applied to the bottom surface 7 of the middle dish receiving recess 1a, ultraviolet irradiation is performed. Well, this work can be done easily in a very short time, the work efficiency is greatly improved, and the cost is greatly reduced. In addition, since the elastic layer 11 is directly bonded and fixed to the bottom surface 7 of the inner dish accommodating recess 1a by the ultraviolet irradiation, the cushioning sheet 35, which was necessary in the conventional example, is attached to the bottom 31a of the body 31. The double-sided adhesive tape 36 to be bonded and fixed can be dispensed with, the number of parts is reduced, and management aspects such as inventory management are simplified.

  In addition, since the elastic layers 11 are provided at the four corners of the bottom surface 7 of the inner tray accommodating recess 1a and the four corners of the inner tray 4 are elastically supported by these four elastic layers 11, the four elastic layers are provided. 11 (ie, the central portion of the space formed between the bottom surface 7 of the middle dish receiving recess 1a and the bottom surface of the middle dish 4) is formed with a gap (this portion). In the embodiment, although the adhesive layer 12 is provided in the central portion, a gap is formed around the adhesive layer 12), and the bottom surface 7 and the intermediate plate 4 of the intermediate plate accommodating recess 1a. The bottom of the is not in direct contact. Therefore, even if the cosmetic container is dropped on the floor or the like, the impact at the time of dropping is softened by the buffering action of each elastic layer 11 and transmitted to the inner plate 4 and the center sandwiched between the elastic layers 11 In the portion (around the adhesive layer 12), the impact is not directly transmitted to the inner tray 4, and the drop strength is high.

  FIG. 3 shows another embodiment of the first cosmetic container of the present invention. In this embodiment, an elastic layer 11 formed by curing an ultraviolet curable silicone adhesive by ultraviolet irradiation is formed on substantially the entire bottom surface 7 of the container receiving recess 1a of the container body 1 (see FIG. 4). ). Further, in order to detachably fix the intermediate dish 4 to the container main body 1, an engaging portion (see FIG. (Not shown) is formed, and an engaged portion (not shown) that is detachably engaged with the engaging portion is formed on a portion of the outer peripheral side surface of the inner tray 4 corresponding to the engaging portion. Yes. Therefore, in this embodiment, the adhesive layer 12 is not formed on the bottom surface 7 of the middle dish accommodating recess 1a of the container body 1. Other parts are the same as those in the above embodiment, and the same reference numerals are given to the same parts. This embodiment also has the same operations and effects as the above embodiment.

The outer elastic layer 15 formed by curing an ultraviolet curable silicone adhesive by ultraviolet irradiation is formed so as to be bent substantially at right angles (see FIG. 6). Each of the outer elastic layers 15 has a substantially circular shape in cross section (see FIG. 7), and in the state where the inner tray 4 is placed, the surface of each outer elastic layer 15 (the inner pan placement surface). However, the inner tray 4 is supported while being slightly recessed due to its elasticity (see FIG. 8). In addition, an inner elastic layer 16 (cured and fixed only to the bottom surface 7) formed by curing an ultraviolet curable silicone adhesive by ultraviolet irradiation is formed in a substantially rectangular frame shape at the center of the bottom surface 7. An adhesive layer 12 having a substantially rectangular shape in plan view is formed inside thereof. Other parts are the same as those in the embodiment shown in FIGS. 1 and 2, and the same reference numerals are given to the same parts. This embodiment also has the same operation and effect as the embodiment shown in FIGS.

  Further, when forming the outer elastic layer 15 in the production of the cosmetic container, in the application step, at the four corners of the bottom surface 7 of the middle dish receiving recess 1a of the container body 1 in the open state, A liquid UV curable silicone adhesive is applied from the nozzle of the coating device or the like so as to extend over the outer peripheral portion of the bottom surface 7 and the lower end portion of the side surface 8, thereby forming a strip-shaped body having a radius of about 2 mm and a cross section of approximately ¼ circle. After the formation, this is cured by irradiating with ultraviolet rays using a mercury lamp or the like of an ultraviolet irradiating device (elastic layer forming step).
