Description

Easy-to-open bottle cap

Technical Field

The utility model relates to a beverage package field, specific saying relates to an easy-open bottle lid.

Background

Various beverages have rich mouthfeel, can greatly meet the requirements of people on the living quality, and are more and more popular with people. The prior bottled beverage mainly comprises various plastic bottles, wherein the upper bottle mouth of each plastic bottle is provided with an external thread, and a bottle cap is connected with the bottle cap in a screwed mode. After the machine is filled with beverage, the bottle cap and the bottle body are screwed tightly, the screwing force is high, so that the bottle body and the bottle cap are slightly deformed, the bottle body and the bottle cap are ensured to be in close contact without a gap, and the external air and microorganisms are prevented from entering the bottle. The bottle cap screwing force of the common beverage bottle is large, and people experiments prove that 3 adult women and 7 adult children cannot unscrew the bottle caps by themselves and need to resort to other people.

In contrast, beverage bottle manufacturers and beverage manufacturers have adopted some methods, one method is to increase the friction force of the outer periphery of the bottle cap, and the outer periphery of the bottle cap is provided with strip-shaped or diamond-shaped stripes to increase the friction force, although the method is widely used, the method cannot solve the problem that part of women and children have weak strength, and only reduces the phenomenon of slipping when part of the bottle is screwed. Another approach is to make larger diameter closures. However, the larger diameter bottle cap requires a larger tightening force to achieve the same sealing effect, and the force required for unscrewing the bottle cap is also increased, so that the problem that the bottle cap is difficult to be opened by people with weak finger strength is difficult to solve.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the weak point of above-mentioned conventional art, provide a bottle lid that opens more easily under the circumstances of the dynamics of not reducing to screw.

The purpose of the utility model is achieved through the following technical measures:

the utility model provides an easy-open bottle lid, includes bottle lid top and bottle lid body, the axle center cavity of bottle lid body sets up, be equipped with the internal thread on the inner wall in bottle lid body axle center, its characterized in that: the periphery of the bottle cap body is provided with a protruding part protruding in the radial direction, and the protruding part is provided with anti-skidding lines.

Preferably, the bottle cap body has a polygonal outer peripheral cross-section, and the corners of the polygonal shape form protrusions. The polygon is a quadrangle, a trilateral, a hexagon or an octagon.

Preferably, the two adjacent protrusions are connected with each other by a plane or an arc surface concave to the axis of the bottle cap body.

Preferably, the connecting surface shape of any one of the protruding portions is different from the connecting surface shape of the protruding portions adjacent to both sides.

Preferably, the any one of the protruding parts is connected with another protruding part adjacent to the proximal end in the unscrewing direction by an arc-shaped surface concave to the axis of the bottle cap body.

As a preferable scheme, the two sides of the protruding portion are provided with extension pieces, each extension piece comprises a fixed extension piece and an adjustable extension piece, the fixed extension piece and the adjustable extension piece are connected at the end portions of the protruding portion, the end of the fixed extension piece, which is far away from the protruding portion, is hinged with the bottle cap body, the end of the adjustable extension piece, which is far away from the protruding portion, is provided with a limiting shaft, the bottle cap body is provided with a guide groove, and the limiting shaft is arranged in the guide groove and can slide along the guide groove.

Preferably, the outer surface of the extension piece is provided with anti-skid projections.

Owing to adopted above-mentioned technical scheme, compare with prior art, the utility model has the advantages that:

the utility model provides an easy-open bottle lid keeps away from the axle center of bottle lid body through the protruding portion, and the effect moment position when the bottle lid is twisted in the increase, the effect lever when the increase that the extension piece is showing more is unscrewed to lever effect improves the dynamics of bottle lid, increases substantially and opens the bottle lid success rate, makes the crowd that the strength is more weak also can easily unscrew the bottle lid, and polygonal outward appearance also has more ornamental value than traditional circular outward appearance.

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Detailed Description

Example 1: as shown in fig. 1, the easy-to-open bottle cap comprises a bottle cap top 1 and a bottle cap body 2, wherein the axis of the bottle cap body 2 is arranged in a hollow manner, an internal thread 21 is arranged on the inner wall of the axis of the bottle cap body 2, a protruding part 22 protruding in the radial direction is arranged on the periphery of the bottle cap body 2, and the protruding part 22 is provided with an anti-skid thread 23.

In the present embodiment, the outer peripheral cross-section of the bottle cap body 2 is a polygon, specifically a quadrangle, and the corners of the polygon form protrusions. The polygon can also be a trilateral, hexagonal or octagonal shape.

In this embodiment, the two adjacent protrusions 22 are connected by a flat surface 24.

Example 2: in the present embodiment, as shown in fig. 2, the outer peripheral cross section of the bottle cap body 2 is a polygon with inwardly recessed side faces, and the corners of the polygon form the protrusions 22. The two adjacent protruding parts 22 are connected with each other by an arc surface 25 concave to the axis of the bottle cap body 2. The rest of this example is the same as example 1.
