Description

Anti-rotation and anti-pulling composite bottle cap

Technical Field

The utility model relates to a white spirit bottle lid structure field, concretely relates to prevent changeing and prevent pulling out compound bottle lid.

Background

The white spirit bottle cap is used as a part of a white spirit bottle process, and the sealing property and the aesthetic property are mainly considered in the bottle cap process design. As shown in fig. 1, the conventional bottle cap structure is generally divided into three layers, wherein the innermost layer is made of plastic, the outer two layers are made of aluminum, and the two layers of aluminum caps are fixed by adhesion. In addition, in recent years, as the anti-counterfeiting requirement of white spirit is higher and higher, the bottle cap is required to be provided with the anti-counterfeiting two-dimensional code which is generally arranged on the plastic cap at the innermost layer, holes are required to be formed in the two layers of aluminum caps in the structure, the bonding area between the two layers of aluminum caps is reduced, and the slipping risk is further improved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a prevent changeing and prevent pulling out compound bottle lid.

The purpose of the utility model is realized through the following technical scheme:

the utility model provides an prevent changeing and prevent pulling out compound bottle lid, includes inner cup, enclosing cover, it is fixed through the viscose between enclosing cover and the inner cup, be provided with at least one recess on the circumference wall of inner cup, be provided with interior concave part on the circumference wall of enclosing cover, recess and interior concave part cooperate each other, specifically, interior concave part one-to-one ground imbed the recess in.

Furthermore, the composite bottle cap further comprises a plastic inner sleeve, and the inner cover is sleeved on the plastic inner sleeve.

Furthermore, the top of the inner cover and the top of the outer cover are provided with holes, and the top of the plastic inner sleeve corresponding to the holes is provided with an anti-counterfeiting two-dimensional code.

Further, the groove is set as a first knurled round concave point, and the inner concave portion is set as a second knurled round concave point.

Furthermore, the first knurled round concave points and the second knurled round concave points are uniformly distributed on the circumferential wall of the inner cover and the circumferential wall of the outer cover respectively.

Further, still be provided with first annular on the circumference wall of inner cup, it is provided with the second annular to correspond first annular on the circumference wall of enclosing cover, first annular and second annular are mutually supported.

Further, the inner cover is an aluminum inner cover, and the outer cover is an aluminum outer cover.

The utility model has the advantages that:

1) the recess on the inner cup circumference wall and the interior concave part on the enclosing cover circumference wall mutually support, thereby increased area of contact between inner cup and the enclosing cover and improved bonding strength, and the relative rotation between annular knurl circle concave point can effectively prevent inner cup and the enclosing cover, also has certain effect of preventing pulling out.

2) The first ring groove on the circumferential wall of the inner cover is matched with the second ring groove on the circumferential wall of the outer cover, so that relative movement between the inner cover and the outer cover is further prevented, and the situation that the outer cover is pulled out and the inner cover is still sleeved on the plastic inner sleeve is avoided.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 2, the utility model provides a technical scheme:

an anti-rotation anti-pulling composite bottle cap comprises an inner cap 1 and an outer cap 2, the outer cap 2 and the inner cap 1 are fixed through viscose, at least one groove is formed in the circumferential wall of the inner cap 1, an inner concave part is formed in the circumferential wall of the outer cap 2, the groove and the inner concave part are matched with each other, and the inner concave part is embedded into the groove in a one-to-one mode. Fixed through the bonding mode between inner cup 1 and the enclosing cover 2, the relative phenomenon of skidding appears easily, through set up recess and interior concave part on inner cup 1 and enclosing cover 2, increase the area of contact of inner cup 1 and enclosing cover 2, improve bonding strength, cooperate the bonding between recess and the interior concave part simultaneously, compare the bonding between the smooth circumference wall, can prevent effectively that the emergence of skidding is relative to rotate between inner cup 1 and the enclosing cover 2 when rotating the bottle lid, also can play certain anti-pulling effect.

Preferably, the composite bottle cap further comprises a plastic inner sleeve 3, and the inner cap 1 is sleeved on the plastic inner sleeve 3.

Preferably, the top of the inner cover 1 and the top of the outer cover 2 are provided with holes, and the top of the plastic inner sleeve 3 corresponding to the holes of the inner cover 1 and the outer cover 2 is provided with an anti-counterfeiting two-dimensional code.
