Description

  The present invention relates to a cosmetic container for storing a solidified cosmetic such as a foundation, eye color, blusher, etc., and in particular, an impact buffering structure of a solidified cosmetic container that is easily damaged by an impact such as a solidified powder foundation. About.

  Conventionally, solidified cosmetics such as solidified powder foundations are likely to be cracked, peeled off or damaged by vibration or impact during transportation or when dropped, and therefore, an effective shock absorbing structure is required. Normally, the solidified cosmetic is filled in a powder form in a container called an inner plate, solidified by a press, stored and held in the inner plate, loaded into the storage recess of the compact container together with the inner plate, and added from the outside. The impact to be absorbed is absorbed by an impact buffering mechanism provided between the inner dish and the compact container.

  As a conventionally well-known shock absorbing mechanism, a shock absorbing material made of a gel material or the like is interposed between the inner dish and the bottom surface of the compact container (Patent Document 1). Such a planar shock absorber is effective for impacts from a direction perpendicular to the surface, but has sufficient shock absorption for impacts parallel to the surface, that is, from the side of the compact container. The effect could not be expected. Therefore, the present applicants effectively absorb not only the bottom surface of the compact container but also the side surface by using a structure in which a spherical silicone gel is interposed at the four corners of the inner plate so that the inner plate is in a floating state. An impact shock absorbing structure has been proposed (Patent Document 2).

  However, any of these conventionally known shock buffering structures has no shock buffering mechanism between the inner plate containing the cosmetic and the lid of the compact container. Cannot be absorbed directly, but is absorbed indirectly by the shock absorbing material on the bottom surface through the middle dish, or by a puff disposed between the middle dish and the lid of the compact container.

  In addition, in order to stably hold the middle dish in the storage recess, the middle dish is bonded to the surface shock absorber, but if the adhesive force is too strong, the replacement of the middle dish will be hindered. No. 1 proposes a structure in which a perforated sheet material is sandwiched between an intermediate dish and an impact absorbing sheet, and the adhesive force is adjusted by the area of the hole. In the floating structure in which spherical silicone gel is interposed at the four corners of the middle dish as in Patent Document 2, the upper surface of the middle dish is held by a puff, or the latching claw on the side surface of the middle dish is retained in the storage recess. Engaging in the groove prevents the middle dish from escaping.

  Adhesion between the intermediate plate and the shock absorber and engagement between the locking claw and the locking groove hinders free swinging of the intermediate plate, and thus hinders the sufficient impact buffering function. . In addition, in the structure held by the puff, if the pouch is forgotten to be put in, the inner plate comes out of the storage recess, and there is a risk of increasing the damage to the cosmetic.

JP 2007-167341 A JP 2007-29234 A

  The present invention holds the upper end of the intermediate dish with a holding frame attached to a compact container, suppresses the swinging of the intermediate dish, and reliably achieves the retention of the intermediate dish in the storage recess while maintaining the elasticity of the holding frame. Absorbs the impact applied to the inner plate to prevent problems such as cosmetic damage due to the impact from the upper surface of the inner plate, and the holding frame is made of two types of resin, hard resin and elastic resin. An object of the present invention is to reduce the number of parts and the assembly process by reducing the manufacturing cost by using an integrally molded product.

  Means taken by the present invention to solve the above problems comprises a container main body having at least one storage recess and a lid for opening and closing the container main body, and the cosmetic is solidified and stored in the storage recess. The middle plate is stored in a replaceable manner, and an impact buffering mechanism is disposed between the middle plate and the storage recess, and the upper end of the middle plate is held by a middle plate holding frame attached to the container body, and the middle plate is held. The portion that contacts the upper end of the inner dish of the frame is made of a material having elasticity.

  The said intermediate tray holding frame consists of two parts, the attachment part attached to a container main body, and the elastic part which contact | abuts elastically at the upper end of an intermediate dish, an attachment part is made from hard resin, and an elastic part has elasticity. It is made of resin, and both parts are integrally molded.

  The tip of the elastic part of the intermediate tray holding frame extending toward the storage recess is terminated at a position that coincides with the inner peripheral surface of the intermediate tray, and a step is generated between the inner peripheral surface of the intermediate tray and the intermediate tray holding frame. It is characterized by not having it.

  A spherical silicone gel is interposed between the intermediate dish and the storage recess, and the intermediate dish is held in the storage recess with a floating structure.

  The solidified cosmetic stored in the inner dish is a powder cosmetic containing 10% or more of functional powder.

  In the present invention, a part of the holding frame that is in contact with the upper end of the inner tray is formed of an elastic material so that the impact applied to the inner tray due to the elastic deformation of the holding frame is absorbed. Combined with the shock absorbing structure disposed in the lower part of the inner dish, it is possible to effectively absorb impacts from any of the four directions below, the side and the top of the compact container. Therefore, it is possible to provide an extremely excellent structure as an impact buffering mechanism for a solidified cosmetic such as a powdery foundation that is vulnerable to impact. In addition, the holding frame is formed by integral molding of two types of resin, a hard resin and an elastic resin, and can be handled as a single part, making the manufacture, management and assembly of the parts simple and easy. Cost can be reduced.

  A preferred embodiment of the present invention will be described with reference to the drawings. 1 and 2 show a compact container incorporating a buffer mechanism according to the present invention, and a container body (1) having two storage recesses (3) and (4), and the body (1) can be freely rotated. The lid (2) is pivotally attached and opens and closes the opened upper surface of the main body. In the first storage recess (3) of the main body (1), an inner plate (5) for storing solidified cosmetics such as powdery foundation in the solidified state is stored, and in the second storage recess (4). Stores an applicator such as a puff or brush. A mirror (6) is fixed on the inner surface of the lid (2). The container body (1) has two storage recesses (3) and (4). However, the present invention is not limited to this, and the storage recess may be single. is there.

  Between the bottom of the middle dish (5) and the first storage recess (3), spherical silicone gels (10) are located at the four corners of the middle dish (5) to form a floating structure. An impact buffering mechanism is provided. The shock absorbing structure is not limited to the floating structure made of such a spherical silicone gel, but may be a shock absorbing structure made of a sheet-like shock absorbing material. And the inner plate does not need to be glued.

  As the floating structure, the structure disclosed in Patent Document 2 is suitable. That is, the spherical silicone gel is easily deformable due to the properties of siloxane bonds, has low creep properties, has high heat resistance, is thermally stable, has high chemical stability, and has a light transmittance of 90% or more. High transparency can be easily obtained, the refractive index can be easily adjusted, and the distribution thereof can be easily adjusted.

  As the silicone gel, those conventionally used and commonly used as various commercially available silicone materials can be appropriately selected and used. Any of a heat curing type or a room temperature curing type, a condensation type or an addition type curing mechanism can be used. The silicone gel preferably has a penetration of JIS K2207-1980 (50 g load) after curing of 10 to 120, more preferably 20 to 100. The diameter of the spherical silicone gel is preferably from 3.0 to 10.0 mm, more preferably from 5.0 to 8.0 mm.

  In the figure, (7) is an inner tray holding frame having a rectangular frame shape that follows the shape of the peripheral portion of the first storage recess (3), and one side portion is freely rotatable to the main body (1). A latch (8) is provided on the other side of the main body (1) and is engaged with the upper end of the inner plate (5). It is attached to the main body (1) while holding the plate. When the middle pan holding frame (7) is opened outward (position shown in FIG. 2) from the middle pan holding position (the position shown in FIG. 1), the holding of the middle pan (5) is released and the middle pan (5) is removed. Can be removed from the storage position and replaced with a new refill pan. The intermediate tray holding frame (7) is an elastic material that elastically holds the rigid resin portion and the upper end of the intermediate tray for exhibiting a reliable holding function, or elastically buffers the contact of the lid with the mirror. It is comprised as a single component which shape | molded two types of resin parts integrally with the resin part which has property.

  Referring to FIG. 5, the mounting portion (7a) of the inner tray holding frame (7) is formed of a hard resin, for example, ABS resin, and the elastic portion (7b) is formed of an elastic resin, for example, a polyester-based elastomer. The The attachment portion (7a) and the elastic portion (7b) are formed as a single part by first forming the attachment portion (7a) and then integrating the elastic portion (7b) with the attachment portion by insert molding. The attachment portion (7a) is a rigid portion for mounting the inner tray holding frame (7) around the first storage recess (3) of the container body (1), and is engaged with the shaft support portion (11) with the body. A stop latch (8) is provided. The elastic portion (7b) protrudes inward from the periphery of the first storage recess (3), and provides elastic contact between the elastic contact portion (12) that contacts the upper end of the inner tray (5) and the mirror. An elastic protrusion (13) is provided. The elastic contact portion (12) that contacts the upper end of the intermediate tray (5) terminates with a length that matches the inner peripheral surface of the intermediate tray (5). In order to prevent the step from being generated between the two, the cosmetic material is devised so that the cosmetic material does not remain on the lower surface of the elastic contact portion when the cosmetic material of the inner dish (5) is removed with a puff.

The rib (14) in FIG. 5 is in contact with the inner periphery of the first storage recess (3) when the middle tray holding frame (7) is engaged with the container body (1). 7) is to prevent the compact container from being displaced in the lateral direction, but due to the strong force from the lateral direction, the ribs get over the inner circumference of the receiving recess (3). There is a risk that the holding frame (7) is lifted, the pressure on the upper end of the middle dish is insufficient, and the middle dish (5) is not sufficiently held.
Therefore, the rib (14) is directed toward the bottom surface of the container body (1) so that the rib (14) does not get over the inner periphery of the first storage recess (3) even against a strong force from the side. It is desirable to extend and make a shape that makes deep contact with the inner periphery of the first storage recess (3). On the other hand, the portion of the rib (14) close to the shaft support portion (11) is first retracted while rotating around the shaft support portion (11) when the inner tray holding frame (7) is engaged with the container body (1). In the extended rib (14), the rib comes into contact with the upper surface of the container body (1) to contact the inner periphery of the recess (3), and the middle tray holding frame (7) is engaged with the container body (1). It becomes difficult to wear. In addition, since the inner tray holding frame (7) is fixed by the shaft support, there is no risk of shifting to the side surface in the portion close to the shaft support portion (11), so the rib (14) of this portion needs to be extended. There are few. From this point of view, FIG. 6 shows a modified example of the rib (14). In the portion excluding the portion close to the shaft support portion (11) from the rib (14) in FIG. Extending about 0.5 mm toward the bottom of (1), in the vicinity of the shaft support (11), the extension amount of the rib (14) is gradually returned by the taper (15), the rib (14) of FIG. The amount of extension is the same as As a result, the middle tray holding frame (7) is prevented from being lifted by a strong force from the side direction without affecting the opening and closing operation of the middle tray holding frame (7), and the middle tray (5) is sufficiently retained. I can do it. Further, as shown in FIG. 6, the rigidity of the inner tray holding frame (7) can be improved by extending the rib (14) toward the bottom surface of the container body (1).

  When an impact is applied to the inner plate (5) and the inner plate (5) swings up and down, the elastic deformation of the elastic contact portion (12) and the elastic deformation of the spherical silicone gel (10) Thus, the vertical movement of the inner tray (5) can be effectively absorbed and buffered, and the impact can be prevented from being transmitted to the cosmetic.

  A compact container body with two storage recesses is loaded with a medium dish containing solidified powder cosmetics consisting of the following formula, and the mounting part is made of ABS resin and the elastic part is integrally molded with polyester elastomer. A cosmetic container that holds an inner dish with a frame and a spherical silicone gel is prepared. As a comparative example, instead of the inner dish holding frame, an engaging claw on the side of the inner dish is used as an engaging groove in the first storage recess. A cosmetic container having a structure in which the inside dish is prevented from escaping and having the same structure in other points was prepared and subjected to an impact resistance test. The test was carried out by repeatedly dropping the cosmetic material in the inverted direction and counting the number of drops until the cosmetic material filled in the inner plate broke and became unusable. As a result of the test, the cosmetic container of the present invention was 14 times, whereas the cosmetic container of the comparative example was 7 times, and the effectiveness of the shock absorbing structure of the cosmetic container of the present invention can be confirmed. did it.

[Prescription example]

  Since the solidified powder cosmetic of the above formulation contains 10% or more of the adjustment powder that is a functional powder, damage such as cracking or breakage is likely to occur due to impact, but it is affected by the shock absorbing mechanism of this invention. It is a cosmetic container that can exhibit extremely excellent effects as a powder cosmetic container and is suitable for storing solid cosmetics such as powdery foundations.
