Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns an airtight compact.

``Problems to be solved by conventional technology and inventions'' In general, cosmetic compacts have a flat body and a lid that are pivoted at the back so that they can be opened and closed, and the closed lid is locked to the body at the front. It's becoming like that.

However, since the body and lid are usually just butted together or loosely fitted together, if you carry it in a handbag or the like, the powdered cosmetics inside may leak due to the posture and vibrations. Come out,
It may stain the surrounding area.

Therefore, recently, the use of packing has been considered and attempted, but so far,
The elasticity of the packing may cause the lid to be pushed up, causing it to open unexpectedly. In addition, in order to avoid this, there is the inconvenience that the engaging means for locking the lid closed must be special, or the dimensional accuracy and material must be very strict.

The present invention eliminates such conventional drawbacks.

``Means for Solving the Problems'' As shown in the drawing, the present invention consists of a flat body 1 made of synthetic resin and a lid 2 that abut against each other at low peripheral walls 11 and 21, and the back It is pivoted 3 so as to be openable and closable, and has an engaging protrusion 12 on the front surface of the peripheral wall 11 of the body, and an engaging protrusion 22 that engages with the engaging protrusion on the front part of the peripheral wall 21 of the lid. In other words, an engaging means is provided to lock and hold the closed lid 2.

The peripheral walls 11 and 21 of the body 1 and the lid 2 have a wide planar shape, and the upper surface of the peripheral wall 11 of the body 1 has a narrow groove 13 on the inside and a wide groove 14 on the outside in parallel. The partition wall 15 between the grooves is formed slightly lower, and the lower surface of the peripheral wall 21 of the lid 2 has a triangular cross section that gradually deepens toward the outside in correspondence with the grooves 13 and 14. A triangular groove 23 is provided around the circumference.

An elastic ring 4 made of rubber or soft synthetic resin is attached to the grooves 13 and 14 on the body 1 side. ) A mounting base 41 is provided, and an elastic flexible part 42 is provided protruding outward from the mounting base 41 and has a rectangular cross section, an upper surface facing diagonally upward, and an outer peripheral edge fitting loosely into the outer groove 14. There is.

In the figure, reference numeral 5 denotes a synthetic resin inner tray housed in the body 1, which directly accommodates powdered cosmetics. 6
is a mirror that is fitted and adhered to the inner surface of the lid 2.

``Function'' Because of the above structure, when the lid 2 is closed, the elastic flexible portion 4 of the elastic ring 4 is inserted into the triangular groove 23 of the lid 2.
2 enters and is pressed into contact with the elastic flexible portion 42, and the elastic flexible portion 42 is pushed down against its own elasticity. By this,
A seal can be obtained, and the elastic ring deforms softly over a wide range in the elastic flexible portion 42, so
The force of this pushing up the lid is small, and the conventional one is sufficient without special consideration of a means for locking the lid.

"Effects of the invention" According to the present invention, sufficient sealing is achieved by the elastic ring 4, and even when carried in a handbag or the like, the powdered cosmetics inside will not leak out due to posture or vibration. Does not pollute the surrounding area.

Also, the peripheral wall 11 of the body 1 and the lid 2 that are butted together,
21 is formed wide, narrow grooves 13 on the inside and wide grooves 14 on the outside are provided in parallel on the upper surface of the peripheral wall 11 of the body 1, and the partition walls 15 between the grooves are formed slightly lower, and , both grooves 1 are formed on the lower surface of the peripheral wall 12 of the lid 2.
A triangular groove 23 with a triangular cross section that gradually deepens toward the outside corresponding to the grooves 13 and 14 of the body 1 is provided around the body 1.
14, an elastic ring 4 made of rubber and soft synthetic resin;
The elastic ring has an elastic flexible portion 42 protruding outward and diagonally upward from the base 41 corresponding to the groove 13 on the inner side, and has an F-shaped cross section. At the same time, the elastic flexible portion 42 is fitted and fixed into the groove 13 on the outside thereof.
Since the elastic ring 4 is loosely fitted into the lid 2 and the elastic flexible portion 42 is pressed into contact with the triangular groove 23 of the closed lid 2, the elastic ring 4 is gently bent and deformed over a wide range in the elastic flexible portion. The force pushing up the lid 2 is small, there is no inconvenience of the lid 2 opening unexpectedly, there is no need to use a special engagement means for locking the lid, and there is no need to be strict about dimensional accuracy or material. , which can be provided at low cost and is extremely useful in practice.
