Screwed cap

Abstract

The invention discloses a screwed cap. A container mouth, a base cap and a top cap are included; a clamping ring is arranged on the base cap, a limiting groove is formed in the outer circumference ofthe container mouth, the clamping ring cooperates with the limiting groove, an inner plug is arranged on the top cap, the top cap and the base cap are in threaded connection, the top cap is rotated, and the container mouth is opened. The screwed cap has the advantages that a sealing member is arranged on the cap, sealing operation can be completed at one time only needing to cover and seal the cap, and two processes of sealing and cap covering are not needed, which is safe, hygienic and reliable; the sealing member is in the container mouth, and a sealing effect is fundamentally achieved fromthe interior; the top cap is rotated and the sealing member can be opened, other tools are not needed, which is convenient and hygienic; the arrangement of a sleeve ring makes taking, placing and carrying convenient; the inner plug is lifted, liquid comes out from a liquid outlet formed in the inner plug, after the liquid comes out, the inner plug is retracted back to the container mouth to ensurethe cleanliness, hygiene and safety of the container mouth, and the container mouth is not stained.

Description

technical field [0001] The invention relates to the field of container caps, in particular to a screw cap. Background technique [0002] With the improvement of people's pursuit of quality of life, the requirements for the storage of substances in life, especially the storage of liquids, are getting higher and higher, which requires higher and higher sealing performance of containers. At present, most of the container lids on the market are sealed by adding a pull ring outside the connection between the container lid and the container mouth, or setting a layer of sealing sheet on the upper end of the container mouth. Adding a sealing pull ring cannot fundamentally achieve the sealing effect. A sealing sheet is installed on the upper end of the container mouth. After opening the lid, it is necessary to tear the sealing sheet manually or puncture the sealing sheet with other tools, which is inconvenient and unhygienic. Setting the sealing sheet on the top is likely to affect ...

Problems solved by technology

At present, most of the container lids on the market are sealed by adding a pull ring outside the connection between the container lid and the container mouth, or setting a layer of sealing sheet on the upper end of the container mouth. Adding a sealing pull ring cannot fundamentally achieve the sealing effect. A sealing sheet is installed on the upper end of the container mouth. After opening the lid, it is necessary to tear the sealing sheet manually or puncture the sealing sheet with other tools, which is inconvenient and unhygienic. Setting the sealing sheet on the top is likely to affect the quality of the liquid in the container during the sealing process

In addition, after the container lid objects on the market are poured out, there will be residues left on the lid mouth, which is not only easy to dirty hands, but also very unhygienic. This headache has been a problem that people have been unable to solve for a long time.
