Description

Anti-overflow seal structure of box body and contain packing material of this structure

Technical Field

The utility model relates to a box body seal structure and contain the packing material of this structure, concretely relates to anti-overflow seal structure and contain the packing material of this structure.

Background

With the rapid development of society, the frequency of using the box body to store articles in life is higher and higher, and the demand is larger and larger. However, in the using process, the conditions that the box body is not sealed well and the stored objects overflow, particularly liquid objects, are often obvious. Therefore, the requirement on the sealing performance of the joint of the cover body and the body of the box body is high, and the overflow is generally prevented by adding a sealing strip in the prior art. However, the sealing strip is generally made of soft material with good elasticity, cannot be made of the same material as the box body, and can only be matched with the box body in a clamping bonding mode and the like, so that the manufacturing cost can be greatly improved. Meanwhile, the phenomenon that the box body is illegally opened to cause the article to be stolen or damaged is easy to occur in the transportation or transfer process. The box should also have an anti-theft function, i.e. it cannot be opened easily after being sealed.

Disclosure of Invention

In order to solve the technical problem, the utility model aims at providing an anti-overflow seal structure of box body, its simple structure, sealed effectual has theftproof, anti-overflow goes out the function.

The utility model adopts the technical scheme as follows:

an anti-overflow sealing structure of a box body comprises a lower sealing part and an upper sealing part, wherein the lower sealing part and the upper sealing part are correspondingly arranged on a body and a cover body of the box body and are used for connecting the box body; a first bulge is arranged on the first wall in the first groove, and a second bulge is arranged on the second wall; the upper sealing part is provided with a second groove, and the second groove comprises a third wall close to the center of the box body and a fourth wall far away from the center of the box body; a third bulge is arranged on the central side of the box body with a fourth wall in the second groove, and a transverse plate is arranged on the side, far away from the central side of the box body, of the fourth wall; the first wall is matched with the second groove; the first protrusion is matched with the third protrusion; the transverse plate is matched with the second protrusion.

Further, the first wall is a box wall of the box body.

Further, the third wall is a cover wall of the box body cover body.

Further, the cross section of the second protrusion is trapezoidal, rectangular or triangular with a chamfer.

Further, the first groove is arranged on the box body in a surrounding mode.

Further, the first groove and the body of the box body are integrally formed.

Further, the second groove is arranged on the cover body of the box body in a surrounding mode.

Furthermore, the second groove and the cover body of the box body are of an integrally formed structure.

A package comprises the anti-overflow sealing structure of the box body.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the sealing structure is formed by the pre-tightening matching of the lower surface of the second protrusion on the first groove and the upper surface of the transverse plate of the second groove, the structure is simple, and the anti-theft function is realized while the sealing function is realized through the pre-tightening contact matching between the second protrusion and the transverse plate. In addition, the sealing structure can also compress the upper sealing part on the lower sealing part, so that the stability of the sealing effect is improved.

The upper surface of the first bulge in the first groove is in close contact fit with the lower surface of the third bulge on the second groove, so that the function of preventing liquid from overflowing is realized, and meanwhile, the first bulge is also used as a fulcrum for pre-tightening deformation of the transverse plate, so that the cantilever end of the transverse plate is easier to fix, seal and mount. Furthermore, due to the presence of the first protrusion as a fulcrum on the lower sealing portion, it is more difficult to disengage the cross plate from the second protrusion after the fixed seal is installed.

Adopt some stronger material preparations of rigidity to have the utility model discloses during anti-overflow seal structure's box body, open seal structure must lead to the fact the destruction of box body, perhaps leave obvious crease to reach the effect of theftproof.
