On the other hand, the recessed part shown with the code | symbol 6 is for accommodating cosmetic tools, such as a puff, for example.
[0009]
Reference numeral 10 denotes a lid body. The lid body 10 has an elliptical shape that is the same shape as the container body 1 when viewed from above, and a wall around the lid 10 faces the wall portion 1a when the lid body 10 is closed. Part 10a is erected. Furthermore, a hook 11 and a convex portion 12 are formed at positions corresponding to the lock mechanism 2 and the concave portion 3 when the lid 10 is closed. Reference numeral 13 denotes a shaft inserted into the convex portion 12 along the longitudinal direction thereof.
[0010]
Reference numeral 14 denotes a recess formed on the back surface 10 b of the lid 10 so as to be coaxial with the recess 5 when the lid 10 is closed. The concave portion 14 has a circular shape when viewed from above, and the inner diameter thereof is larger than the outer diameter of the peripheral wall portion 7. Further, the recess 14 is covered with a stretchable film (elastic member) 15 stretched on the back surface 10b. As a result, a space S surrounded by the back surface of the recess 14 and the film 15 is formed in the recess 14. It is formed.
[0011]
In the case of this example, the film 15 is formed by cutting a sheet having stretchability and gas shielding properties into a circle having a larger diameter than the recess 14. For the material of the film 15, for example, natural rubber, various synthetic rubbers, acrylic resins, and the like can be used. Preferably, unstretched nylon, unstretched urethane, and the like are used. Furthermore, it is desirable that the color tone of the film 15 is light or transparent so as not to impair the aesthetics of the compact container. On the other hand, a method such as heat fusion or adhesion is used for stretching the film 15 on the back surface 10b.
[0012]
Reference numeral 16 denotes a groove-like vent hole formed on the inner peripheral surface from the wall 10 a to the recess 14, and the space S is communicated with the outside air by the vent hole 16. Reference numeral 17 denotes a mirror fixed to the back surface 10b adjacent to the recess 14. And the convex part 12 is fitted to the recessed part 3, and the compact container is formed by attaching the cover body 10 to the container main body 1 by using the shaft 13 as a fulcrum. Moreover, what is necessary is just to engage the lock mechanism 2 and the hook 11 when closing the cover body 10. FIG.
[0013]
By the way, in the case of the present embodiment, the space S is formed in the recess 14 by the stretchable film 15 stretched on the back surface 10b, and when the height of the peripheral wall portion 7 closes the lid body 10, The upper end edge 7a of the peripheral wall portion 7 is adjusted so as to protrude toward the space S side. Therefore, when the lid 10 is closed, the upper end edge 7a of the peripheral wall portion 7 comes into contact with the membrane 15 from below, and protrudes toward the space S side while pushing up the membrane 15 from the position indicated by symbol A in FIG. To do.
[0014]
As a result, since the film 15 is elastically pressed against the upper end edge 7a of the peripheral wall portion 7 and closely contacts the upper end edge 7a of the peripheral wall portion 7, the airtightness of the accommodating portion 9 is ensured and the object to be accommodated is airtightly retained. Is possible. Compared to the conventional compact container, the structure of the lid 10 and the membrane 15 is simple, and the membrane 15 can be easily arranged on the lid 10.
[0015]
That is, according to this example, a compact container capable of airtight holding of the object to be stored can be provided inexpensively and easily. Furthermore, since the accommodating part 9 is covered with the film | membrane 15 over the whole surface, the film | membrane 15 acts as a lid | cover of the accommodating part 9, and there also exists an effect that scattering of the to-be-contained object from the accommodating part 9 is prevented.
[0016]
Further, when the peripheral wall portion 7 pushes up the membrane 15, the volume of the space S decreases. However, since the reduced air is discharged from the vent hole 16 to the outside air, the air in the space S is reduced as the volume of the space S decreases. Is compressed and the internal pressure of the space S does not increase. Accordingly, the protrusion of the peripheral wall 7 toward the space S and the contact between the upper end edge 7a of the peripheral wall 7 and the film 15 are smoothly performed.
[0017]
On the other hand, when the engagement between the lock mechanism 2 and the hook 11 is released, the film 15 that has been pushed up to the position indicated by the symbol B returns to the position indicated by the symbol A due to its own elasticity, and the upper end edge 7a of the peripheral wall portion 7 is restored. Is elastically pressed downward. As a result, the lid body 10 automatically jumps upward as the lock mechanism 2 and the hook 11 are disengaged, and the lid body 10 can be easily opened.
[0018]
FIG. 3 is an enlarged view of a part of a cross section of a compact container showing an example of another embodiment of the compact container according to the present invention. In this example, an inner tray 8 that accommodates an object to be accommodated in a peripheral wall portion 7 that extends above a cylindrical concave portion 5 has an upper end edge 8 a that covers the upper end edge 7 a of the peripheral wall portion 7 from above. It is arranged like this. The height of the inner tray 8 is adjusted so that the upper edge 8a of the inner tray 8 protrudes toward the space S when the lid 10 is closed. On the other hand, reference numerals 20 and 21 denote protrusions formed along the circumferential direction on the inner peripheral surface of the recess 5 and the outer peripheral surface of the inner tray 8, respectively. Is held in.
[0019]
When the lid 10 is closed, the upper edge 8a of the inner tray 8 comes into contact with the film 15 from below, pushes up the film 15 from the position indicated by reference sign A in FIG. As a result, the film 15 is elastically pressed against the upper end edge 8a and is in close contact with the upper end edge 8a, the airtightness of the accommodating portion 9 is ensured, and the object to be accommodated can be hermetically retained. Further, the structure of the lid 10 and the membrane 15 is simple, and the membrane 15 can be easily disposed on the lid 10. That is, also in this example, a compact container having the same excellent effect as in the first example can be obtained.
[0020]
FIG. 4 is an enlarged view of a part of a cross section of a compact container showing an example of another embodiment of the compact container according to the present invention. In this example, an annular fixing ring 30 is fitted and fixed to the back surface 10 b so as to surround the recess 14, and the end of the film 15 is supported between the back surface of the lid 10 and the fixing ring 30. By doing so, the film 15 is stretched on the recess 14.
[0021]
Here, for example, a method such as ultrasonic bonding is used to fix the fixing ring 30 to the back surface 10b. Reference numeral 22 denotes a groove formed on the outer peripheral surface of the inner tray 8 along the circumferential direction. The engagement between the groove 22 and the protrusion 20 formed on the inner peripheral surface of the recess 5 causes the inner tray 8 to be recessed. 5 is held. And also in this example, the compact container which has the same outstanding effect as the said 1st example is obtained.
[0022]
In each of the above examples, the description has been given of the compact container in which the concave portion 5 that accommodates an object to be accommodated and the concave portion 6 that accommodates a puff or the like are arranged in parallel on the left and right sides of the container body 1. , 6 can be applied to a compact container arranged in tandem before and after the container body 1, a compact container having no recess 6, or a multistage compact container.
