Container cap equipped with function for unfolding state

Abstract

The invention relates to a cap with stay-open function, including a tamper ring to be prevented from separation from a spout of a container, a cap body for screwing to an outer circumferential surfaceof the spout of the container, a hinge portion for interconnecting the cap body and the tamper ring over a circumferential portion of a cutout section defined by and between the cap body and the tamper ring, and bridges configured to connect the cap body and the tamper ring at intervals along the circumferential portion of the cutout section, and to be cut when the cap body is opened. The hinge portion has both side edges, which are respectively adjacent to the cutout section, deepen from an outer surface toward an inner surface of the cap body to form bending indents integrated with the capbody and the tamper ring, and to include a lower longitudinally central area extending downwardly to form a protrusion. The tamper ring has a longitudinally central area including a section set to form a slit, and to have an area corresponding to the projection with a space maintained and indented downwardly by a depth to form a recess.

Description

technical field [0001] The invention relates to a container cap with the function of maintaining an open state, in particular, relates to a container cap with the function of maintaining an open state, which is in a state of being connected with a display ring, and the display ring remains fixed on the bottle mouth of the container , Moreover, the lid main body for opening and sealing the container opening is in the state of being opened as far as possible from the container opening in the state of opening the container opening. Background technique [0002] Generally, a container for containing drinking water including mineral water or liquid substances such as oil, paint, chemicals, etc. is formed with a bottle mouth for the liquid substances to enter and exit. [0003] In addition, a container cap for opening and sealing the opening of the bottle mouth of the container is provided on the bottle mouth to restrict the entry and exit of liquid objects. [0004] like Figure...

AI Technical Summary

Problems solved by technology

[0020] However, extending the length of the support frame 32 cannot finally provide force for the support frame 32 to be close to the inner wall of the bottle mouth N of the container B and can only become the state of being hung up. Therefore, the lid main body 16 is opened from the opening of the container B. If the angle is less than 90°, it is troublesome for the user to take measures by hand so that the lid main body 16 is located at a position where it does not interfere with the opening of the container B.

[0021] In addition, in order to solve the above-mentioned problem, in prior art 3, a protruding portion that is locked corresponding to the locking convex portion C or the external thread M / S formed on the mouth N of the container B is formed at the position of the support frame 32. However, the protruding portion T protrudes from the outer surface of the cap main body 16 when the opening of the bottle mouth N of the container B is sealed, so when the user wants to open the opening of the container B, it hinders the user and causes inconvenience. convenient

[0022] Moreover, in the state where the cover main body 16 is opened, the connection parts P1 to P3 between the display ring 18 on the upper side of the slot 24 and the hinge part 22 and the cover main body 16 are forcibly twisted, so there is a Thin parts of P1 to P3 are subject to a physical force between the force to restore in a twisted state and the support force of the support frame, and are prone to disconnection, and thus the cover body 16 is in danger of being lost.
