Description

Spin-on cap with built-in brewing function

The present invention relates to a bottle cap for use in a bottle for brewing beverages, and more particularly to a spin-on bottle cap having a built-in brewing function.

As shown in the new patent of TW M575011 in China, it provides a bottle cap which has the function of accommodating a brewing additive, and the composition of the bottle cap comprises a first cylindrical structure and an axially mounted on the first cylindrical structure. In the second tubular structure, the second cylindrical structure is selectively rotatable relative to the first cylindrical structure, and the first cylindrical structure is provided with a mouth film at the bottom end of the axial perforation, and the second cylindrical structure The rotating portion is coaxially disposed outside the second set of the first cylindrical structure, and the bottom end of the rotating portion is provided with a tearable stop ring for limiting the rotating portion relative to the first tube a position of a top portion of the first set of the structure, the second cylindrical structure extending into the perforation of the first cylindrical structure with a hollow skirt therein, and the inside of the hollow skirt of the second cylindrical structure The space between the parafilms can accommodate the brewing additive, and the bottom end of the hollow skirt has cutting teeth capable of cutting the parafilm.

The cap can accommodate the brewing additive and is sealed on the bottle mouth structure of the bottle in a first cylindrical structure. When the user wants to fill the bottle with the brewing additive, the previous second tube The retaining ring at the bottom end of the structural structure is torn away, and then the rotating portion of the second cylindrical structure is rotated, so that the cutting teeth at the bottom end of the skirt portion of the second cylindrical structure are cut into the sealing film at the bottom end of the first cylindrical structure to make the sealing The brewing additive in the skirt above the film drops into the bottle for brewing.

Although the bottle cap has the function of accommodating the brewing additive, the user can fill the water in the bottle by brewing the brewing additive in the bottle cap according to the needs of the user, but when the user drinks, the user mouth Contacting the second set of drinking beverages in the first tubular structure, because the second set of joints is an open tubular structure, does not have the function of filtering the waste residue, thereby causing the user to drink easily during drinking The existing bottle cap has the problem of inconvenient use.

On the other hand, when the user fills the brewing additive packaged in the bottle cap into the water in the bottle, the second tubular structure is rotated after the retaining ring at the bottom end of the second cylindrical structure is torn off. The rotating portion rotates and cuts the sealing film located at the bottom end of the first cylindrical structure by the cutting teeth at the bottom end of the skirt of the second cylindrical structure, and is easy to excessively rotate the second cylindrical structure due to the manner of rotating the sealing film It is difficult to precisely control the slit size of the sealing film by the rotation, and the sealing film is completely cut off from the bottom end of the skirt of the first cylindrical structure and dropped into the bottle, which causes inconvenience in use.

The purpose of the present invention is to provide a spinning type cap with a built-in brewing function, which solves the problem that the existing cap does not have a filter residue function, and the user is easy to drink the waste residue.

In order to achieve the foregoing objects, the present invention provides a spin-on bottle cap system having a built-in brewing function, comprising:  An outer cover body includes an outer cover base portion and a duct portion, the outer cover base portion includes a peripheral cover peripheral wall and a ring top plate, and an inner peripheral surface of the outer cover peripheral wall forms an outer cover threaded portion, and the ring top plate is formed on the outer cover a top portion of the peripheral wall of the outer cover, the duct portion extends downward from above the top plate of the ring to a lower portion of the top plate of the ring, and a guiding hole is formed inside the duct portion, and an opening is formed between the duct portion and the peripheral wall of the outer cover a downwardly facing assembly space, the bottom end of the conduit portion is for sealing a film, and the outer peripheral surface of the portion of the conduit portion above the base of the outer cover forms an externally threaded portion, and the inner peripheral surface of the conduit portion is formed At least one limit stop;  An inner cover body is disposed inside the duct portion of the outer cover body and can be pressed down from the upper portion of the sealing film to a predetermined position, the inner cover body including an inner cover top plate and an inner tube portion a cutting portion, a plurality of filtering holes are formed in the top plate of the inner cover, the inner cylindrical portion is formed on a periphery of the top plate of the inner cover and extends downward, and an outer circumferential surface of the inner cylindrical portion forms a plurality of annular limiting flanges arranged at upper and lower intervals The annular limiting flange can be selectively restrained by the limiting portion of the outer cover and pass through the limiting portion, and the cutting portion is formed on a periphery of the bottom end of the inner cylindrical portion. When the cover is pressed down to the predetermined position, the cutting portion is used to cut a part of the sealing film at the bottom end of the conduit portion, and the remaining portion of the sealing film is still connected to the bottom end of the conduit portion;  a spinning cover body rotatably sleeved on the outer cover body and the upper end of the inner cover body, the spinning cover body comprising a screw cover base portion and a blocking portion, the inner peripheral surface of the screw cap base portion being formed An inner threaded portion, and the cap base portion can be screwed to the outer cap portion of the outer cap body, and the cap base can rotatably press the inner cap body, and the stopper portion can be torn Separately formed on a bottom edge of the base of the cap, the stop is located above the ring top plate of the outer cover.  

By the novel creation of the above-mentioned spin-on bottle cap, when the inside is filled with the brewing material and the sealing film is sealed, it can provide a user to install the port on the container filled with water, and its characteristics are as follows:  1.
