Abstract

The utility model provides a bottle cap with an anti-theft ring having an edge-folding structure. The bottle cap comprises a cap body and the anti-theft ring, wherein the cover body and the anti-theft ring are integrated through a cross structure; and the bottle cap is characterized in that the edge-folding structure consisting of stoppers and connecting ribs is formed on the inner circumference of the anti-theft ring; and anti-turn protrusions are arranged on upper edges of the stoppers on the edge-folding structure. According to the technical scheme, a stop ring on a bottle opening body can be pressed by the anti-turn protrusions on the upper edges of the stoppers on the edge-folding structure, the applied moment of the edge-folding structure on the stop ring is increased, the edge-folding structure can be effectively prevented from turning in the process of opening the bottle cap, the anti-theft ring and the cover body can be successfully separated, an anti-theft mark function is effectively realized, and the safety of foods in the bottle is improved.

Description

A kind of anti-theft ring has the bottle cap of flanging structure

Technical field

The utility model relates to a kind of bottle cap with anti-theft ring, particularly has the bottle cap of stop tab at the anti-theft ring inner peripheral surface.

Background technology

General plastic bottle lid connects an anti-theft ring by a body one end and forms.Wherein the internal face system of this body is provided with screw thread, and the internal face of this anti-theft ring has and upwards bends and present plane stop tab.Have some discontinuous segment joint-cuttings between this outer body and the anti-theft ring, and between each adjacent joint-cutting, form a connection bridge formation.

Above-mentioned plastic bottle lid is that the bottleneck with bottle is spirally connected in the use.When opening for the first time, this anti-theft ring can whether go up rise with the flange that the stop tab top is against the bottleneck outer peripheral face, and body then opens application force and rises with turning round, and twists off the bridge formation that is connected between body and anti-theft ring simultaneously.Know that this plastic bottle lid structure has in the use and seal a bottle by above, and the function of antitheft and improper unlatching.

Because the most employing of bottle cap has certain elastomeric plastic material and processes; Existing stop tab structure is rotated uphill process at bottle cap; Stop tab is received on the bottleneck and is overturn after the effect of stopping ring compression; Anti-theft ring is crossed the stopping ring after expanding, and anti-theft ring and bottle cap break away from bottleneck together, and anti-theft ring has lost the effect whether accurate sign container was opened.

Summary of the invention

The purpose of the utility model is to provide opens the bottle cap that stopping ring in the bottle cap process can not break away from bottleneck together with lid after a kind of capping.

For achieving the above object; The technical scheme that the utility model adopted is: a kind of anti-theft ring has the bottle cap of flanging structure; Comprise lid, anti-theft ring; Constitute one through connecting bridge between lid and the anti-theft ring, have the flanging structure that is made up of stop tab and dowel on the described anti-theft ring inner peripheral surface, the upper edge of the structural stop tab of described flanging is provided with the anti-canting projection.

Described flanging structure and anti-theft ring lower edge are one-body molded.

The quantity of described stop tab is 6-12, is arranged in equably in the anti-theft ring inner peripheral surface.

The quantity of described anti-canting projection is 3-6, is spaced apart and arranged in the upper edge of stop tab.

The Distance Matching of the stopping ring on the distance of described anti-canting projection to anti-theft ring lower edge and anti-theft ring lower edge to the body of desiring to seal a bottle.

The junction of described stop tab and described anti-theft ring is provided with outgate.

Be provided with the screw thread and sealing convex edge of the body coupling that seals a bottle in the described lid.

In the utility model technical scheme; The anti-canting projection of the structural stop tab of flanging upper edge can prop up the stopping ring on the bottleneck body; Increased the flanging structure to stopping ring applied moment, can prevent effectively that the flanging structure from overturning in bottle lid opening process, anti-theft ring can be separated with lid smoothly; Effectively play the antitheft marked effect, improved the safety of food in the bottle.

Description of drawings

Fig. 1 is the Bottle cap structure scheme drawing that the anti-theft ring of the utility model has the flanging structure.

Fig. 2 has the bottle cap cross-sectional view of flanging structure for the anti-theft ring of the utility model.

Fig. 3 has the practical state cross-sectional view of bottle cap of flanging structure for the anti-theft ring of the utility model.

The specific embodiment

Below in conjunction with Figure of description, utility model is made specific descriptions:

It is as depicted in figs. 1 and 2,

The anti-theft ring (2) of lid of plastic material (1) and material material; Through the integrated through injection molding moulding; Between lid (1) and anti-theft ring (2), cut the interrupted slit of formation with cutter and form connecting bridge; The inner peripheral surface of anti-theft ring (1) be provided with by 8 stop tab (21) and between the flanging structure (20) that constitutes of dowel (22); The upper edge of the stop tab (21) on the flanging structure (20) is provided with anti-canting projection (23); 4 anti-canting projections (23) are spaced apart and arranged in the upper edge of stop tab (21), the Distance Matching of the stopping ring (31) on the distance of anti-canting projection (23) to anti-theft ring (2) lower edge and anti-theft ring (21) lower edge to the body (3) of desiring to seal a bottle, and flanging structure (20) is one-body molded with anti-theft ring (2) lower edge; The junction of stop tab (21) and described anti-theft ring (2) is provided with outgate (24), be provided with in the lid (1) and the screw thread (11) of the body that seals a bottle (3) coupling with seal convex edge (12).

As shown in Figure 3; In the utility model technical scheme, the anti-anti-canting projection (23) of stop tab (21) upper edge on the flanging structure (20) can prop up the stopping ring (31) on the bottleneck body (3), has increased flanging structure (20) to stopping ring (31) applied moment; Can prevent effectively that flanging structure (20) from overturning in bottle lid opening process; Anti-theft ring (2) can be separated with lid (1) smoothly, effectively plays the antitheft marked effect, has improved the safety of food in the bottle.
