Abstract

A bottle closure includes an upper cover (1) and a lower cover (2). The upper cover (1) connected to the lower cover (2) can be fastened on the lower cover (2), and the lower cover (2) has inner thread suitable to the bottle and is provided with a suction nozzle (3). There is a vent hole (5) on the lower cover (2),which can be sealed by a cone-shaped protuberance on the upper cover (1). A plastic spacer and a pad are located in the inner space of the lower cover (2). The pad impacts the plastic spacer to fix the plastic spacer in the inner space of the lower cover (2). The plastic spacer is configured as a concave ring with a cut. The concavity of the concave ring is a quarter of a semicircle. Holes are arranged on the pad uniformly. There is a lock structure between the upper cover and the lower cover. The bottle closure can avoid the liquid to spill out from the bottle and makes it easy to drink the liquid in the bottle.

Description

Specification

#细 or

[I] The utility model relates to a bottle cap, in particular to a technique for improving an existing cap.

[2] At present, there are fewer products sold in the market with faucet caps, and the existing similar products also have large defects, that is, when people drink sputum, the faucets on the cap are contained in In the mouth, it takes a lot of suction to drink the liquid in the bottle. If it is a child or an elderly person, it is often difficult to drink because of its small lung capacity, which is inconvenient for people to use. In addition, the existing bottle with a faucet cap has another significant disadvantage, that is, when the bottle is accidentally dropped, the liquid in the bottle is oozing out through the faucet, and the place around the bottle is wetted. The existing caps cannot meet the requirements of large production because of their complicated structure and low production efficiency.

[3] The object of the present invention is to provide a bottle cap which can easily drink the liquid in the bottle and has a simple structure and prevents the bottle from pouring out and escaping the liquid.

[4] The purpose of the utility model is achieved by the following technical solutions:

[5] A bottle cap, comprising an upper cover and a lower cover, the upper cover is connected to the lower cover and can be fastened to the lower cover, the inner cover is provided with an internal thread matched with the bottle liner, and the lower cover is provided with a water nozzle, The utility model is characterized in that: the lower cover is provided with a vent hole, and the upper cover is provided with a conical protrusion for sealing the vent hole.

[6] The inner cover of the lower cover is provided with a functional gasket and a pad, and the pad is pressed and fixed in the inner cavity of the lower cover

[7] The functional gasket has an annular shape, and the annular position is recessed by a quarter and a semicircle; the functional gasket has a ring at the ring position.

[8] The pad is uniformly provided with a circular through hole.

[9] A snap structure is arranged between the upper cover and the lower cover.

[10] Compared with the prior art, the utility model has the following advantages:

[II] Since there is a vent hole on the lower cover, when people drink it, although the suction port on the bottle cap is contained in the mouth, because of the setting of the vent port, the pressure in the bottle and the outside of the bottle Atmospheric pressure The vacuum inside the bottle is destroyed, and under the action of atmospheric pressure, people can easily suck the liquid into the bottle. When the upper cover is fastened to the lower cover 吋, the conical protrusion on the upper cover seals the vent hole to prevent the liquid in the bottle from pouring out, and the fastening structure between the upper and lower covers can fasten the upper and lower covers to avoid automatic disengagement. The slit provided on the functional gasket is closed when the bottle is placed flat or fallen, and the slit is automatically closed under the pressure of water to prevent the water in the bottle from pouring out. The bottle cap of the utility model has the advantages of simple structure, small number of parts, simple and convenient installation, high production efficiency, and is very suitable for mass production.

difficult

[14] The bottle cap of the present invention will be further described in detail below with reference to the accompanying drawings.

[15] As shown in FIG. 1 and FIG. 2, the bottle cap of the present invention is mainly composed of an upper cover 1 and a lower cover 2, and a water nozzle 3 is disposed at a central position of the lower cover, and an inner cavity of the lower cover is provided. The internal thread 4, the lower cover is screwed onto the bottle mouth by an internal thread, and the vent hole 5 is provided at a side of the lower cover. The upper cover is matched with the lower cover, and the upper cover is fastened to the lower cover by the fastening structure 6, and the upper cover and the lower cover are connected by a flexible film, and the upper cover is provided with a tapered protrusion 7 at a position corresponding to the ventilation hole, when The upper cover is fastened on the lower cover, and the tapered protrusion seals the vent hole to prevent the liquid in the bottle from flowing out of the vent hole. In the inner cavity of the lower cover, there are also functional gaskets 8 and pads 9, and the functional gaskets are pressed into the inner cavity of the lower cover through the pads. The functional gasket has a "several" shape, and the periphery of the functional gasket is a concave semi-circular annular structure. At the annular position, there is a mouth 10, when the bottle is placed flat or fallen, the slit is The water is automatically closed under the pressure of the water to prevent the liquid in the bottle from pouring out. The circular periphery of the pad is uniformly provided with a circular through hole 11 , and the outlet of the circular through hole is located at a concave semicircle of the functional gasket. The bottle cap of the utility model has the advantages of simple structure, convenient installation and high production efficiency, and meets the requirements of large production.
