Description

Anti-theft plastic bottle cap with densification and leakage prevention structure

Technical Field

The utility model relates to the technical field of plastic packaging bottle caps, in particular to an anti-theft plastic bottle cap with a densification anti-leakage structure.

Background

At present, plastic sealing anti-theft bottle caps, in particular sealing caps for drinking water, are receiving increasing attention for their quality. However, the sealing cover of the drinking water bottle in the prior art is easy to leak and has poor anti-theft effect because the sealing inner plug and the anti-theft structure are unreasonable. The two reasons are summarized as follows: only a single-layer sealing ring is used, leakage is difficult to effectively prevent, the sealing effect is not ideal, the sealing deformation area of the sealing ring is large, the sealing ring is easy to break, the bottle cap can be unscrewed only with great force due to large uncapping torque, and sometimes even the bottle cap cannot be clamped; the anti-theft ring is connected by the easy-breaking ribs, so that the cover body is separated from the anti-theft ring when the bottle cap is opened, the anti-theft ring is easy to separate from the bottle neck, and the anti-theft effect is poor.

When the existing plastic bottle cap is used, the elasticity of the sealing ring is reduced due to the fact that the single-layer sealing ring is extruded for a long time, a gap appears between the sealing ring and a bottle opening, the plastic bottle cap is revealed, and the plastic bottle cap is not beneficial to improving the practicability of the plastic bottle cap.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides an anti-theft plastic bottle cap with a densification and leakage prevention structure, which solves the problem that the elasticity of a single-layer sealing ring of the existing plastic bottle cap is reduced due to the long-time extrusion of the sealing ring.

In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides an anti-theft plastic bottle lid with increase density and prevent leaking structure, includes lid, lower lid, go up through connecting bridge fixed connection between lid and the lower lid, go up the inside fixed internal thread that is equipped with of lid, the hasp has evenly been seted up to lid inside down, go up the stopper in the first annular of the inside top fixed connection of lid, stopper in the inside top fixed connection second annular of last lid of stopper in the first annular, stopper outside cover is equipped with sealed the pad in the first annular.

Preferably, the fixed ring of inside fixed connection of stopper in the first annular of stopper below in the second annular, fixed ring and the stopper sliding connection in the second annular.

Preferably, the second annular inner plug is provided with a ring groove on the inner side.

Preferably, a hard plastic plate is fixedly arranged at the top end of the upper cover body.

Preferably, a plurality of layers of annular anti-slip hooks are fixedly arranged inside the sealing gasket.

Preferably, the bottom end of the sealing gasket is fixedly provided with a soft plastic ring, and the top end of the sealing gasket is provided with a hollow groove.

Advantageous effects

The utility model provides an anti-theft plastic bottle cap with a densification and leakage prevention structure. Compared with the prior art, the method has the following beneficial effects:

(1) this theftproof plastics bottle lid with densification prevention of seepage leak structure, stopper carries out the antiseep through stopper in first annular and the second annular and handles the plastic bottle, stopper in close contact with prevents that liquid leaks out in the bottle in bottleneck and the first annular, stopper elasticity reduces in avoiding first annular through stopper in supporting first annular in the second annular, appear the space between stopper and the bottleneck in the first annular that leads to, make the device can be better the seepage of avoiding the bottleneck, the practicality of device has been improved, the application scope of device has been expanded.

(2) This theftproof plastics bottle lid with increase density seepage prevention structure seals the bottleneck top through sealed the pad, places sealed the pad through cyclic annular antiskid hook simultaneously and drops, can make the internal thread and be connected between the bottleneck appear becoming flexible through sealed the pad, has further improved the practicality of device.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows:

referring to fig. 1-3, an anti-theft plastic bottle cap with a densification and leakage prevention structure comprises an upper cap body 1 and a lower cap body 2, wherein the upper cap body 1 and the lower cap body 2 are fixedly connected through a connecting bridge 3, internal threads 4 are fixedly arranged inside the upper cap body 1, lock catches 5 are uniformly arranged inside the lower cap body 2, a first annular inner plug 6 is fixedly connected to the top end inside the upper cap body 1, the first annular inner plug 6 is tightly connected with a bottle mouth to prevent internal leakage, a second annular inner plug 7 is fixedly connected to the top end inside the upper cap body 1 inside the first annular inner plug 6, a sealing gasket 8 is sleeved outside the first annular inner plug 6, a fixing ring 9 is fixedly connected to the inside of the first annular inner plug 6 below the second annular inner plug 7, the fixing ring 9 is slidably connected with the second annular inner plug 7, and the bottom end of the first annular inner plug 6 is supported by the second annular inner plug 7 when being squeezed and folded through the contact of the fixing ring 9 and the second annular inner plug 7, an annular groove 10 is formed in the inner side of the second annular inner plug 7, and the bending direction of the second annular inner plug 7 is guided through the annular groove 10.
