Cover

Abstract

The invention discloses a cover which comprises a rotary cover, a lower cover and a water outlet pipe. The lower cover is provided with a water outlet; the cover is characterized in that the water outlet pipe penetrates through the rotary cover and is propped against the bottom of the lower cover; the water outlet pipe can seal the water outlet; the rotary cover comprises a casing and a buckling part positioned in the casing; the lower cover is provided with a ring-shaped groove for containing the buckling part; at least one axial notch groove is formed in the outer wall of the buckling part; the cover is also provided with a lifting valve; the lifting valve is connected with the ring-shaped groove through threads; at least one lug boss is formed on the outer wall of the lifting valve; the lug boss is arranged in the notch groove; and the lifting valve is connected with the water outlet pipe. The cover has a simple structure, is convenient to operate, is not separated from a container, such as a cup, a kettle and a bottle, during sealing, opening and closing, is low in manufacture cost, ensures that a sealing ring and the water outlet pipe integrally form a whole body through injection moulding, has high connection strength, is not easy to drop off, and has high sealing safety.

Description

technical field [0001] The invention relates to a component of a container, in particular to a cover. Background technique [0002] At present, the cap structure in the industry is usually a simple threaded or button type. The structure and function of screw-on lids are relatively simple, and the lid must be separated from containers such as cups, pots, and bottles to achieve airtight opening and closing; the structure of button-type lids is usually more complicated, the manufacturing cost is higher, and it is prone to water leakage. damage. [0003] Chinese patent: the patent number is "ZL201020516474.9", and the name is "cup cover". A similar structural solution is provided, but this structure has the following disadvantages: There is a limit groove between the bolt body and the telescopic cup body, and it is more laborious to rotate. The water outlet channel of this structure is narrow, resulting in a small water output, which is inconvenient to use; the structure uses ...

The structure and function of screw-on lids are relatively simple, and the lid must be separated from containers such as cups, pots, and bottles to achieve airtight opening and closing; the structure of button-type lids is usually more complicated, the manufacturing cost is higher, and it is prone to water leakage, and it is also easy to use. damage

[0003] Chinese patent: the patent number is "ZL201020516474.9", and the name is "cup cover". A similar structural solution is provided, but this structure has the following disadvantages: There is a limit groove between the bolt body and the telescopic cup body, and it is more laborious to rotate. ;The water outlet channel of this structure is narrow, resulting in a small water output, which is inconvenient to use; this structure uses many sealing rings, and the production and use process will cause a high probability of the sealing ring falling off or being damaged, which will easily cause the cover to leak
