Abstract

The utility model relates to a beer bottle and a cap with thread. The utility model, equipped with a metal cap, is provided with external screw thread around the external surface of the mouth of a beer bottle. An internal screw thread, formed by the extrusion action to the internal surface of the cap in case of pressing the cap, fits the external screw thread. In case of a need to open the cap, a dedicated uncapping tool can be abandoned but a force of certain level can be used for uncapping for direct drink. A pressure in the beer bottle is qualified in terms of safety.

Description

Beer bottle and bottle cap with spiral screw thread

Technical field

The utility model relates to a kind of bottle and bottle cap, particularly relates to a kind of beer bottle and bottle cap with spiral screw thread.

Background technology

The bottleneck of commercially available ordinary beer bottle as shown in Figure 1, its top is provided with the flange of an annular, be illustrated in figure 2 as the beer bottle bottle cap, this beer bottle bottle cap is by the diel punching press, crown cap is held on the flange of this bottleneck, when needs are opened the beer Bottle and bottle cap of this structure, generally need to use special tool to open, do not having to be difficult to open beer bottle under the situation of opener, bringing very big inconvenience for thus customer's use.

The utility model content

The purpose of this utility model is to disclose a kind of beer bottle and bottle cap with spiral screw thread, by this technical scheme, solves existing beer bottle and opens inconvenient problem.

Design concept of the present utility model is: be provided with outside thread on the outside face of this bottleneck, lid can squeeze out the negative thread that is complementary with this outside thread at the inside face of bottle cap when pressing bottle cap.When needs are opened bottle cap, as long as rotate bottle cap, just can like a cork beer bottle be opened, and no longer need to use special-purpose opener.

The concrete technical scheme that the utility model provides is as follows: a kind of beer bottle and bottle cap with spiral screw thread, comprise the beer Bottle and bottle cap, this bottle cap upper shield is on the bottleneck of this beer bottle, the outside face of this bottleneck is provided with outside thread, is formed with the negative thread that is complementary with this outside thread under the squeezing action of the inside face of this bottle cap when lid is pressed.

In order to accelerate the speed of uncork, the outside thread on this bottleneck outside face is a multiple screw thread, the multiple screw thread that the screw thread that this bottle cap inside face forms is complementary for the multiple screw thread with this bottleneck, multiple screw thread rectangular distribution.

Described multiple screw thread is triple screw or four-head screw thread, and the length of thread is half of bottleneck outer perimeter.

Can be the thread of projection with the outside thread of being located on the outside face of bottleneck as required, then the negative thread that forms on this bottle cap inside face be the thread of depression, and this outside thread and this negative thread are complementary.

In contrast, also can be the thread of depression at the outside thread on the outside face of bottleneck, then the negative thread that forms on this bottle cap inside face is the thread of projection, this outside thread and this negative thread are complementary.

Because the rigidity of metallic material is better than non-metallic material, described bottle cap adopts metallic material.

Beer bottle and bottle cap with spiral screw thread of the present utility model in use, can directly firmly rotate bottle cap, just can open and drink, and be very convenient.Pressure of the inside of a bottle reaches safety requirements fully.

Be elaborated as follows by specific embodiment to details of the present utility model and characteristics below in conjunction with accompanying drawing:

Description of drawings

Fig. 1 is the bottleneck of beer bottle in the prior art;

Fig. 2 is the bottle cap of beer bottle in the prior art;

Fig. 3 is an embodiment of beer bottle bottleneck of the present utility model;

Fig. 4 is the scheme drawing of the bottle cap upper shield of beer bottle of the present utility model at the beer bottle bottleneck.

The specific embodiment

As shown in Figure 3, be an embodiment of the bottleneck 2 of beer bottle of the present utility model, beer bottleneck 2 is positioned at the top of beer bottle 3, this bottleneck 2 does not comprise as the annular lip 21 ' (shown in Figure 1) that is positioned at bottleneck 2 ' top in the prior art, is provided with outside thread on the outside face around this bottleneck 2.Screw thread among this embodiment is the four-head screw thread, promptly comprises the single thread of four-head 22,22 ' and 22 ", an other thread is positioned at the opposite of thread 22 ', and thread 22 ' symmetrical distribution (cannot see in the drawings, thereby do not indicate).The length of every thread is about half of bottleneck 2 outer perimeters.

Fig. 4 is the utility model embodiment one, for the scheme drawing of bottle cap 1 upper shield on beer bottle bottleneck 2 of this beer bottle, when gland, because squeezing action, the inside face of bottle cap 1 can form the negative thread that is complementary with external thread of bottleneck 22, and this negative thread also comprises four thread 11,11 ' and 11 ".A same other thread is positioned at the opposite of thread 11 ', and thread 11 ' symmetrical distribution (cannot see in the drawings, thereby do not indicate).

What be worth special version is that the thread of being located on the beer bottle cap does not need prior punch forming.The concrete technology of bottle cap 1 suit is as follows, after being provided with the intact beer of externally threaded beer bottle can, bottle cap 1 is sleeved on the bottleneck 2, when gland, because the gland mould is to the extruding around the bottle cap 1, make bottle cap 1 around along with outside thread distortion, form the negative thread consistent naturally at the inside face of bottle cap 1 with it.Just the screw thread with bottleneck copies on the bottle cap 1.

According to actual conditions, can use another one embodiment of the present utility model, the triple screw line promptly is set around bottleneck.This triple screw line distributes equably.In this embodiment, on bottle cap 1, will stamp out the triple screw line consistent with the thread of bottleneck.Because the represented embodiment principle of the method for this embodiment and Fig. 3 and Fig. 4 is identical, no longer indicates with accompanying drawing at this.

Can be thread of projection with the outside thread of being located on the outside face of bottleneck 2 22 as required, then the negative thread 11 that extruding forms on this bottle cap 1 inside face be thread of depression, and this outside thread 22 and this negative thread 11 are complementary.

In contrast, can at the outside thread on the outside face of bottleneck 2 22 thread of depression also, then the negative thread 11 that extruding forms on this bottle cap inside face is thread of projection, this outside thread 22 and this negative thread 11 are complementary.

Because have certain pressure in the beer bottle, in order to keep sealing intensity, this bottle cap 1 adopts metallic material as existing ordinary beer bottle cap.

Embodiment recited above; only be that the utility model preferred embodiment is described; be not that the utility model structure and scope are limited; under the prerequisite that does not break away from the utility model design concept; this area and industry engineering staff, various modification and improvement to technology of the present utility model is made all should fall into protection domain of the present utility model; the utility model is asked for protection technology contents, all is documented in claims.
