Description

[Detailed description of the invention] [Industrial application field] This invention relates to a cosmetic container such as a compact.

[Conventional technology]

2. Description of the Related Art Conventionally, in the field of cosmetic containers such as compacts, cosmetic compacts are known in which a container body and a lid are hingedly connected and locking means such as engaging protrusions are provided on the periphery of each. However, when opening the lid of this compact, a strong force is required to disengage the engaging protrusion on the container body and the engaging protrusion on the lid, making it difficult to open the lid. In the end,
The engaging protrusion may be damaged.

Therefore, a recess is formed in the outer peripheral edge of the container body, both ends of the plastic strip are pinned to both ends of the recess, arms are extended from the plastic strip, and a second engagement protrusion is attached to the tip of the recess. the engaging protrusion is moved inward by the inward bending of the plastic strip to disengage it from the first engaging protrusion formed on the claw piece of the lid; A compact container with an openable lid was proposed (Utility Model Application Publication No. 58-91309).

[Problem that the invention attempts to solve]

However, in this compact container, the second engaging protrusion is integrally formed with the plastic strip by the arm, and when the plastic strip is bent inward, the second engaging protrusion is inserted together with the arm. Slide it towards the
Since the engagement between the two engaging protrusions is released, a space for sliding is required, and the lid opening/closing mechanism becomes large in size. Furthermore, an arm is also required to integrate the second engaging protrusion into the plastic strip, which also has the disadvantage of increasing the number of parts. Moreover, the compact container has small holes at both ends of the plastic strip, which are fitted into pins implanted at both ends of the recess in the container body, so that both ends of the plastic strip are inserted into both ends of the recess 7. Since they are fixedly attached, a considerable degree of precision is required for mutual positioning of the small holes in the plastic strip and the pins, which also has the disadvantage of increasing costs.

This invention provides a cosmetic container that allows the lid to be opened and closed easily and reliably in one operation without increasing the size of the lid opening/closing mechanism, increasing the number of parts, or increasing costs. Its purpose is to

〔Example〕

FIG. 1 shows an embodiment of this invention. This compact is constructed by connecting a main body 1 in the shape of a substantially thick disk and a lid 2 in the form of a thin disk so that they can be opened and closed via a hinge (hidden from view). That is, a notch 4 is provided on the back side of the main body 1, and a coupling protrusion 5 provided on the inner surface of the lid 2 is fitted into the notch 4 and fixed with a pin 6 (FIG. 2). Thereby, the lid body 2 can be opened and closed centering on the pin 6. The main body 1 has a cosmetic storage recess 7 formed in the center of its surface, and a cutout recess 9 that opens outward on the front side of the outer periphery. This cutout recess 9 is made up of a back wall surface 10 and cotton 11 on both left and right sides, and has a
A first engaging protrusion 12 extending in the lateral direction is formed, and protrusions 14 are formed facing inward on both left and right side surfaces 11, respectively.
The tips of these protrusions 14 are rounded off to form forward-facing slopes 15. In the cutout recess 9, an elastic piece 16 having a substantially U-shaped cross section is attached to the notch recess 9 so as to close the outward opening thereof. By fitting the mounting holes 19 provided on both lateral sides of the U-shape into the protrusions 14 on both sides of the notch recess 9 using the elasticity of the lateral sides themselves, as shown in B. Fixed installation. When fitting into the mounting hole 19, the tip slope 15 of the protrusion 14 effectively acts to ensure smooth fitting. This elastic piece 16 is given elasticity as a whole by the above-mentioned shape, and the U-shaped vertical side is formed in the pressing part 17, and when it is pressed, it will move as shown by the chain line A. It is designed to elastically deform (curve) inward. In addition, from the point of view of the aesthetic appearance of the compact, the pressing part 17 consisting of the U-shaped vertical side is curved in an arch shape so as to form a part of the outer peripheral surface of the substantially disc-shaped container 1. A fitting protrusion 21 that fits into the notched recess 9 when the lid 2 is closed is formed on the inner side of the lid 2 corresponding to the notched recess 9 of the main body 1 . The inner surface of the fitting protrusion 21 has a second engagement protrusion 12 that engages with the first engagement protrusion 12 of the notch recess 9 to maintain the closed state when the lid body 2 shown in FIG. 2 is closed. An engaging protrusion 13 is formed. The outer surface of the fitting protrusion 21 is a downwardly tapered surface 1 that is slightly curved.
8, so that the upper end of the pressing portion 17 of the elastic piece 16 comes into contact when the lid body 2 is closed. 23 is a mirror provided on the inner surface of the lid body 2; 24
2 is a cosmetic, and 25 is a container for storing it.

In this configuration, from the state where the lid body 2 is closed (the state shown in FIG. 2), the pressing portion 17 of the elastic piece 16
When pressed, the pressing portion 17 elastically deforms inward, changing from the state shown by the chain line in FIG. 3 to the state shown by the solid line.
Due to this inward elastic deformation of the pressing portion 17, the upper end of the pressing portion 17 pushes up the tapered surface 18, thereby causing the engagement between the second engagement protrusion 13 and the first engagement protrusion 12. It comes off and the lid 2 can be opened. To close the lid 2, rotate the lid 2 downward around the pin 6 and press lightly to engage the second engagement ridge 13 and the first engagement ridge 12. This can be done by

In this manner, the container of this invention can open the lid 2 by one action of pressing the pressing portion 17.

Although the material of the elastic piece 16 is not explained in the above embodiment, it is preferably made of plastic from the viewpoint of elasticity. Further, in the embodiment, the entire outward facing surface of the fitting protrusion 21 is formed as the downwardly tapered surface 18, but a portion thereof may be formed as the downwardly tapered surface 18. Further, the surface shape of the tapered surface 18 may not be slightly curved as in the embodiment, but may be straight or may have another shape. In any case, it is sufficient that the entire surface is tapered. In addition, this tapered surface 18
The upper end of the pressing portion 17 may be made into a tapered surface in response to this. In this way, the lid 2 can be opened even more smoothly by the pressing part 17.

[Effect of idea]

As described above, the cosmetic container of this invention has a second engagement protrusion that engages with the first engagement protrusion of the lid.
A large slide is provided on the back wall surface of the notch recess of the main body, and the engagement between the first engagement protrusion and the second engagement protrusion is released using only the inward bending of the elastic piece. Can be made smaller without requiring space. In addition, this cosmetic container has the second engaging protrusion as described above.
Since it is provided on the back wall surface of the cutout recess itself, an arm like the one disclosed in the above-mentioned publication is not necessary, and the number of parts can be reduced. Further, in this cosmetic container, the elastic piece has a U-shaped cross section,
A locked part is provided on both sides of the U-shape, and the elasticity of the sides is used to lock this into the locking parts provided on both the left and right sides of the notched recess of the main body. There is no need to make it that high. That is, even if the width of the elastic piece is slightly out of line with the width of the notch recess, the deviation is absorbed by the elasticity of the U-shaped lateral sides of the U-shaped elastic piece and the elasticity of the elastic piece itself. Therefore, the cosmetic container of the present application does not require high precision as in the above-mentioned publication, and together with the simplified structure, the cost can be reduced considerably.
