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 eliminates such conventional drawbacks.

``Means for Solving the Problems'' As shown in the drawing, the present invention is such that a flat body 1 made of synthetic resin and a lid 2 are brought into contact with each other at low peripheral walls 11 and 21 so that they slightly fit together. It is pivoted 3 on the back so that it can be opened and closed freely, and the wall around the body 1
An engaging protrusion 12 is provided on the front surface of the lid 1, and an engaging protrusion 22 that engages with the engaging protrusion is integrally provided on the front side of the peripheral wall 21 of the lid to lock and hold the closed lid 2. That's what I do.

The circumferential wall 11 of the body 1 has a planar shape that is wide inwardly, and the circumferential wall 21 of the lid 2 is sufficiently narrower than that.

On the inner surface of the top wall 24 of the lid 2, a hat-shaped synthetic resin mirror holder 7 having a smaller diameter and shallower than the inner surface of the surrounding wall 21 is adhesively fixed at an appropriate distance from the inner surface of the surrounding wall 21. An elastic ring 4 made of rubber, soft synthetic resin, or the like is sandwiched and attached between the lid top wall 24 and the lid top wall 71 . In this case, the elastic ring 4 is provided with a mounting base 43 that is clamped (glued at that time if necessary) as described above, and is moved diagonally downward while maintaining a space between the mounting base and the top wall 24 of the lid. An elastic flexible portion 44 is provided in a protruding manner.
The elastic flexible portion is connected to the flange 71 and the peripheral wall 21 of the lid.
It is movably inserted between it and the inner surface, and its outer edge projects slightly downward from the peripheral wall 21.

In the figure, 5 is a synthetic resin inner plate housed in the body 1, and 6 is a mirror fitted and adhered into the mirror holder 7.

``Effect'' Since the structure is as shown above, when the lid 2 is closed, the body 1
The outer edge of the elastic ring 4 is pressed against the upper surface of the peripheral wall 11, and the elastic flexible portion 44 of the elastic ring is pushed up against its own elasticity. Therefore, not only can sealing be achieved, but also in the elastic flexible portion 44,
Since the deformation is gentle and over a wide range, 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 44, so that the force pushing up the lid 2 is small, and there is no inconvenience of the lid 2 opening 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] The flat body 1 and the 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 engaging means is provided at the front, so that the peripheral wall 11 of the body 1 is made wider inward. A hat-shaped mirror holder 7 having a smaller diameter and shallower than the inner periphery of the peripheral wall 21 is adhesively fixed to the inner surface of the top wall 24 of the lid 2 at an appropriate distance from the inner periphery of the peripheral wall 21, and the flange 71 of the mirror holder 7 is fixed. An elastic ring 4 made of rubber, soft synthetic resin, etc. is sandwiched between the top wall 24 of the lid and the top wall 24 of the lid. The elastic flexible part 44 is movably protruded diagonally downward into the space between the parts, and the outer edge of the elastic flexible part 44 is made to protrude slightly below the peripheral wall 21 so as to be attached to the upper surface of the peripheral wall 11 of the body 1. An airtight compact characterized by pressure welding.
