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 are disadvantages such as having to use a special engaging means for locking the lid closed, or having to make the dimensional accuracy and material very strict.

The present invention is intended to eliminate 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, which are brought into contact with each other by low peripheral walls 11 and 21, and can be opened and closed at the back. Pivot to 3
An engaging protrusion 12 is integrally provided on the front surface of the peripheral wall 11 of the body 1, and an engaging protrusion 22 that engages with the engaging protrusion is integrally provided on the front part of the peripheral wall 21 of the lid. A mechanism is taken to lock and hold the lid closed.

The peripheral wall 11 of the body 1 has a planar shape similar to the peripheral wall 21 of the lid 2.
An elastic ring 4 made of rubber, soft synthetic resin, etc. is fitted inside the peripheral wall 11, and a synthetic resin frame 8 having an L-shaped cross section is fitted inside the elastic ring. The elastic ring 4 is held down by being fitted and fixed. Then, if necessary, adhesive means are taken for these fittings.

In this case, the elastic ring 4 is provided with a mounting base 45 having an L-shaped cross section for the fitting, and is an elastic flexible ring that projects upward from the mounting base and gradually becomes thinner and curves outward in an arc shape. A portion 46 is provided protrudingly.

The circumferential wall 21 of the lid 2 is narrow as described above, but the lid has a groove immediately inside the circumferential wall 21 and
Corresponding to the elastic ring 4, a thick part 25 slightly recessed from the lower surface of the peripheral wall is provided as a peripheral wall, and a mirror 6 is placed inside this.
are mated and glued.

In the figure, 5 is a synthetic resin inner plate.

"Operation" With the above structure, when the lid 2 is closed, the elastic flexible part 46 of the elastic ring 4 is pressed against the lower surface of the thick part 25 of the lid 2, and the elastic flexible part 46 is moved by its own elasticity. resists and is pushed down. Therefore, since a seal is obtained and the elastic flexible portion 46 is gently deformed, the force for pushing up the lid is small, and there is no need to particularly consider 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.

In addition, the elastic ring 4 is softly bent and deformed over a wide range in the elastic flexible portion 46, and therefore, the force pushing up the lid 2 is small, and there is no inconvenience that the lid 2 opens unexpectedly, and the engagement means for locking the lid is closed. There is no need to make special parts, etc., and there is no need to be strict about dimensional accuracy or material, and it can be provided at low cost, which is extremely useful in practice.

Claims (1)

[Scope of utility model registration request] A flat body 1 and a lid 2 are overlapped with the end surfaces of the peripheral walls 11 and 21 facing each other, and are pivotally connected to each other at the back, and an engagement means is provided at the front, so that the peripheral wall 11 of the body 1 is made wider inward. An elastic ring 4 made of rubber, soft synthetic resin, etc. is fitted inside the peripheral wall 11, and a synthetic resin frame 8 having an L-shaped cross section is fitted and fixed inside the elastic ring 4. Hold the elastic ring 4,
The elastic ring 4 is provided with a mounting base 45 having an L-shaped cross section for fitting, and has an elastic flexible portion 46 that projects upward from the mounting base and gradually becomes thinner and curves outward in an arc shape. An airtight compact characterized in that the elastic flexible portion 46 is pressed against the peripheral edge of the top wall of the closed lid 2.
