Cup cover and cup with same

Technical Field

The utility model relates to a cup manufacturing field especially relates to a bowl cover and be equipped with cup of this bowl cover.

Background

At present, when a cup is manufactured, in order to prevent the water leakage problem of the cup, a sealing ring is usually additionally arranged in a cup cover. However, such a cup is prone to leakage due to damage of the seal ring after long-term use, and the seal ring is stained, making it difficult to clean.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems of easy leakage and difficult cleaning of a sealing ring of the existing cup, the utility model provides a cup cover, wherein a sealing convex ring is arranged on the cover bottom of the cup cover, the sealing convex ring is concentric with the side wall of the cup cover, and a sealing locking groove for accommodating the cup mouth of the cup body is formed between the sealing convex ring and the side wall of the cup cover; when the cup mouth of the cup body is inserted into the sealing locking groove, the sealing convex ring is inserted into the cup mouth and is in interference fit with the inner wall of the cup mouth.

The utility model discloses the bowl cover utilizes the sealed locked groove that forms between the lateral wall of sealed protruding circle and bowl cover to block the rim of a cup of cup to the inner wall interference fit who utilizes the lateral wall of sealed protruding circle and rim of a cup realizes the sealed of cup, avoids the cup to appear leaking when using. Therefore, the cup cover of the utility model cancels the common sealing ring in the existing cup cover under the premise of ensuring the sealing with the cup body, can avoid the leakage of the cup caused by the damage of the sealing ring, is convenient to clean and is sanitary to use.

Preferably, the outer side wall of the sealing convex ring inclines towards the direction far away from the side wall of the cup cover. Like this, both can improve the laminating degree between the lateral wall of sealed protruding circle and the inner wall of rim of a cup, improve the sealing performance of cup promptly, make things convenient for during the user of service plants the rim of a cup of cup to the sealed locked groove on the bowl cover again, facilitate the use.

Preferably, the side wall of the cup cover is provided with an internal thread for connecting the cup body. Therefore, the cup cover is connected with the cup body through threads, when the cup is used, the cup can be opened or closed only by screwing, and the use is convenient. Furthermore, the internal thread is formed by semi-annular thread sections at two ends, and the two thread sections are staggered at the butt joint to form a screwing inlet. Therefore, at least two screwing inlets are formed on the cup cover, a user can open or close the cup cover by only screwing the half ring when using the cup cover, and the use is convenient.

In addition, the utility model also provides a cup, be equipped with above-mentioned arbitrary bowl cover on this cup's the cup. The cup is sealed by the aid of the sealing convex ring which is arranged on the cup cover and is in interference fit with the cup opening, and the cup is simple in structure and convenient to clean.

Drawings

FIG. 1 is a schematic structural view of the cup cover of the present invention;

FIG. 2 is a schematic sectional view of the cup cover of the present invention;

fig. 3 is a schematic view of the sectional structure of the cup cover of the present invention when the cup cover is assembled on the cup body.

Detailed Description

The following describes the cup lid and the cup with the lid in detail with reference to fig. 1 to 3.

As shown in fig. 1 to 3, a sealing convex ring 11 is arranged on the bottom of the cup lid 1 of the present invention, the sealing convex ring 11 is concentric with the side wall 12 of the cup lid 1, and a sealing locking groove 13 for accommodating the cup mouth of the cup body 2 is formed between the sealing convex ring 11 and the side wall 12 of the cup lid 1; when the rim 21 of the cup body 2 is inserted into the sealing lock groove, the sealing convex ring 11 is inserted into the rim 21 and is in interference fit with the inner wall (not indicated in the figure) of the rim 21. Preferably, the outer side wall 111 of the sealing collar 11 is inclined away from the side wall 12 of the lid 1. Like this, both can improve the laminating degree between the inner wall of lateral wall 111 of sealed convex ring 11 and rim of a cup, improve the sealing performance of cup promptly, make things convenient for user of service to plant the rim of a cup 21 of cup 2 in the sealed locked groove 13 on the bowl cover 1 when using again, facilitate the use. Preferably, the sidewall 12 of the lid 1 is provided with internal threads for attachment to the cup 2. Therefore, the cup cover 1 is connected with the cup body 2 through threads, and when the cup is used, the cup can be opened or closed only by screwing, so that the use is convenient. Preferably, the internal thread is formed by two semi-annular thread segments 121, and the two thread segments 121 are staggered at the joint to form a screw inlet 122. Therefore, at least two screwing inlets 122 are formed on the cup cover 1, so that a user can open or close the cup cover 1 by only screwing a half circle when using the cup cover, and the use is convenient.
