If the cover is closed to the opening of the body, the opening of the opening of the body is surely sandwiched by the clamping space to achieve an airtight vacuum. The effect can be applied to a high humidity environment or climate, thereby increasing the shelf life of the contained objects.

Description

Tank device

The present invention relates to a can body device, and more particularly to a can body device having a better moisture-proof effect made of plastic.

According to the conventional design, the can body made of plastic material is used for objects that must be protected from moisture (for example, electronic components, medical test strips), and desiccant is generally placed at the bottom of the can body to achieve moisture-proof effect. . However, the tank is column-shaped, and the objects far from the bottom of the tank are far away from the desiccant. Therefore, the moisture resistance of the objects near the tank is not good, and the tank is shaped due to tolerances during manufacturing. The sealing effect between the body and the cover is not ideal. Therefore, objects placed in the tank in a high humidity environment or climate are easily deteriorated, and the effect of being preserved is not long.

The purpose of the present invention is to provide a can body device, the seal between the body and the cover of the can body has the double effect of inserting and buffering, and can overcome the tolerance problem of molding during manufacturing, so that the body of the can body and The seal between the seals achieves a gas-tight vacuum effect, and can be applied to a high humidity environment or climate, thereby increasing the shelf life of the contained objects.

In order to achieve the above object, the present invention includes a body having a one-way opening and a cover that closes the opening of the body, wherein the cover has an outer peripheral surface and an inner surface. a circumferential surface, and a flexible interposed space is formed between the inner circumferential surface and the outer circumferential surface. If the cover is closed to the opening of the main body, the opening margin of the main body is taken by the clamping space. It is indeed sandwiched between them, so that the outside air cannot enter the tank to achieve a gas-tight vacuum effect.

A further feature of the present invention is that a locking device is disposed between the peripheral edge of the body and the inner circumferential surface and the outer circumferential surface, and the clamping device includes at least one flange disposed on a periphery of the opening, and At least one ridge provided on the inner circumferential surface and the outer circumferential surface, the flange and the ridge are mutually inserted to make the sealing effect of the cover and the opening of the body better.

The first figure is an exploded perspective view of the creation of the can body device.

The second figure is a perspective combination of the first figure.

The third and fourth figures are a front view and a side view of the second figure.

The fifth figure is a cross-sectional view taken along line A-A of the third figure.

Referring to the first to fifth figures, the creation of the can body device 1 includes: a body 2 and a cover 3, wherein the body 2 is a long cylindrical hollow body made of high-density PE or PP plastic material, having an opening 21 and The bottom portion 22 is provided with a flange 23 on the outer side of the opening 21.

The cover 3 has an outer peripheral surface 31 and an inner peripheral surface 32. The outer peripheral surface 31 is provided with a plurality of concave and convex strips 311 to provide a frictional force to facilitate the operation when the cover is closed, and the front edge of the cover 3 is provided with a tongue 312. , is conducive to the basis of force when opening. A flexible interposed space 33 is formed between the outer peripheral surface 31 and the inner peripheral surface 32 for clamping the periphery of the opening 21 of the main body 2. It is worth mentioning that the interposing space 33 sandwiches the The depth of the opening periphery of the body is one-third of the full height of the outer peripheral surface 31. Preferably, the inner peripheral surface 31 and the outer peripheral surface 32 are provided with ridges 311, 321 so as to be mutually engaged with the flange 23 so that outside air cannot enter the can, so that the cover 3 and the opening 21 of the body 2 are provided. The cover is brought to an airtight vacuum effect. In addition, the cover 3 is provided with a receiving chamber 34. The receiving chamber 34 is spaced apart from the inner peripheral surface 32 for receiving the molecular sieve desiccant, and the receiving chamber 34 is provided with a reinforcing rib 35. .

In summary, the present can body device holds the periphery of the opening 21 of the body 2 by the flexible clamping space 33, and the inner peripheral surface 31 and the outer peripheral surface 32 are provided with ridges 311, 321 and the body. The flanges 23 of the opening 21 of the opening 21 are mutually inserted, so that the outside air cannot enter the can, so that the cover 3 and the cover of the body 2 can achieve an airtight vacuum effect, and the receiving chamber 34 is matched with the cover 3. The molecular sieve desiccant contained in the tank can improve the moisture-proof effect of the objects placed in the tank and improve the storage time.

In summary, the creation of the can body device can achieve the purpose of creation, in line with the new patent requirements, but the above is only the preferred embodiment of the creation, and the various modifications and changes according to the creation should still be included. Within the scope of this patent application.
