Description
Technical Field
The invention belongs to the field of beverage caps, and particularly relates to a beverage cap capable of stabilizing rupture of membranes.
Background
The bottle mouth sealing film type beverage bottle has the advantages of tight package, difficult liquid leakage, pollution and the like, and has wide application prospect. Such mouths are required to be equipped with membrane-breakable beverage caps, commercially available as well-known caps, li Legai, etc.
The flat beverage cover with smaller cover body thickness has shorter extension stroke of the inner container for rupture of the membrane, so that the sealing membrane of the bottle mouth can be not easy to be punctured. Currently, the industry uses a thick, high-thickness beverage cap with a thicker cap body to increase the extension stroke of the liner.
However, the arrangement of the beverage bottle has a plurality of defects that firstly the material cost and the process cost of the beverage cap are increased and secondly the appearance of the beverage bottle is affected. In order to avoid the defects to realize smooth membrane rupture, many European enterprises such as German and Kangmei corporation adopt materials for optimizing and replacing the sealing membrane, so that the sealing membrane is softer and is easier to break, and the sealing membrane is ensured to be easily broken by saw teeth at the lower edge of the inner container, thereby realizing smooth membrane rupture.
However, in the market of China, such sealing films are not popularized, so that the sealing films are actually used in domestic beverage bottles, or the sealing films are thicker and harder in the old, and the common flat beverage caps cannot be successfully punctured. The reason why the conventional flat beverage cap cannot be smoothly pierced is as follows:
the beverage cover is a plastic part, under the capability of the existing process, the dimensional tolerance of the plastic part is larger, so that the threaded fit tolerance between the cover cap and the liner is larger, the liner is easy to shake, and after the saw teeth at the lower edge of the liner are contacted with the sealing film, the film cannot be broken due to difficult force application caused by shaking;
the beverage cover is flat, the extending stroke of the inner container is shorter, and the saw teeth at the lower edge of the inner container cannot be sent to deeper parts;
the domestic sealing film is thicker and harder, and generally has at least two layers of structures, so that the domestic sealing film is not easy to be scratched by saw teeth at the lower edge of the liner.
Disclosure of Invention
The invention aims to solve the technical problem of providing a beverage cover capable of stably breaking films, which can realize the purposes of being applicable to various sealing films and stably breaking films.

Detailed Description
First embodiment: referring to fig. 1-4, a beverage cap capable of stably breaking a membrane comprises a cap base 1, an inner container 2 and a cap 3.
The cover seat 1 is arranged at the bottle mouth; the external thread and the internal thread of the cover seat 1 are reversely arranged; the inner container 2 is connected in the opening of the cover seat 1 in a threaded manner. The external thread of the liner 2 is double-thread, and the internal thread of the cover seat 1 is double-thread matched with the external thread. In the internal threads of the cover seat 1, tight-fit strips 11 are arranged between each upper thread and each lower thread, and the number of the tight-fit strips 11 is a plurality; the tight-fit strip 11 and the thread where it is located form a gap, which is a rotation channel for the thread fit. The space between the upper thread and the lower thread in the embodiment is the space between each circle of two thread lines a and b of the double thread as shown in fig. 4; if the cover seat 1 and the liner 2 are both provided with single thread, the space between the upper thread and the lower thread is defined as the space between each circle of threads.
In this embodiment, the tight-fitting strips 11 are all disposed at the upper ends of the threads on the lower side, and keep a gap with the threads on the upper side, so as to form a rotation channel for threaded engagement between the liner 2 and the cover seat 1. By the arrangement, the tight fitting strip 11 is attached to the thread on the lower side, so that the production is facilitated, the process difficulty is reduced, and the gap size between the tight fitting strip 11 and the thread on the upper side can be facilitated.
The clearance between the tightening strip 11 and the thread on which it is located tends to decrease in the direction of rotation of the liner 2, i.e. the higher the tightening strip 11 is, the closer it is to the thread line on its upper side. The arrangement is that the more the liner 2 rotates downwards, the more tightly the cover seat 1 is matched with the liner; firstly, the liner 2 can be ensured to be convenient to twist during initial rotation, and the use feeling is good; secondly, can also guarantee that inner bag 2 is close to seal membrane time and lid 1 close-fitting, be difficult for rocking, can stab in the seal membrane steadily.
In this embodiment, the tight-fitting bar 11 is adjacent to the end face of the rotation passage, and the thread lead angle thereof is the same as that of the other thread constituting the rotation passage. By the arrangement, the liner 2 and the cover seat 1 can rotate smoothly during screwing.
The cap 3 is in threaded connection with the outer side of the cap seat 1 to block the opening of the cap seat 1; the cover cap 3 is selectively abutted against the inner container 2 to drive the inner container 2 to rotate along with the inner container; the cap 3 is fed in the opposite direction to the liner 2.
Specifically, the bottom of the cap 3 is fixedly provided with a plurality of steering contact pieces 31; the inner wall of the liner 2 is fixedly provided with a matched steering clamping block 21; during installation, the steering contact piece 31 is embedded in the liner 2 and is abutted against the side edge of the steering clamping block 21, so that the liner 2 is driven to move towards the sealing film by the way when the cap 3 rotates to be separated from the cap seat 1.
Wherein, the included angle between one side surface of the steering clamping block 21 and the inner side wall of the corresponding liner 2 is an acute angle so as to form a clamping groove for accommodating the steering contact piece 31; the included angle between the other side surface of the steering clamping block 21 and the inner side wall of the corresponding liner 2 is an obtuse angle, and the steering contact piece 31 is made of plastic or elastic materials, so that the steering contact piece 31 can fall into the clamping groove through rotation during installation. By means of the arrangement, the cap 3 can be inserted into the liner 2 at will, and the steering contact piece 31 deforms to slide across the obtuse side face through reverse rotation to fall into the corresponding clamping groove smoothly, so that the installation convenience between the liner 2 and the cap 3 is improved.
In addition, two close-fitting protruding points 23 are symmetrically and fixedly arranged at the upper end of the outer peripheral surface of the inner container 2; the two close-fitting bumps 23 are symmetrically distributed between the tail ends of the two threads. The close-fitting protruding points 23 are all located at the extending sides of the tail parts of the external threads of the inner container 2, and preferably, the close-fitting protruding points 23 are located at the lower sides of the extending lines of the tail parts of the external threads of the inner container 2, so that when the inner container 2 rotates in operation, after the close-fitting protruding points 23 enter a rotating channel, the close-fitting protruding points are in interference abutting-against with the end faces of the close-fitting strips 11, and the matching tightness of the inner container 2 and the closure 1 is improved.
Because the close-fitting protruding points 23 are positioned at the upper end of the outer peripheral surface of the liner 2, the close-fitting protruding points 23 only enter the rotating channel when the liner 2 rotates in the later period, so that the matching tightness of the liner 2 and the cover plug 1 is improved, and the labor-saving rotation of the liner 2 in the earlier period is ensured.
