The present invention belongs to the field of cup lids fitted to cups, and specifically pertains to a cup lid and a thermos cup.
Cups are a type of containers commonly used in people's daily life for drinking tea, water and beverages. Common cups are generally divided into direct drinking cups or straw cups. The direct drinking cups allow direct drinking by screwing off cup lids or through direct drinking ports on the cup lids. Open cups are not a good choice for scenarios such as sports and outdoor activities, so the open cups are often equipped with cup lids and sealing lids, and most cups generally have only one drinking port in actual use. The direct drinking cups or the straw cups generally allow only one drinking mode, resulting in relatively single function and design mode of the cups. For example, patent No. CN110652157B titled “THERMOS CUP WITH DUAL-PURPOSE CUP LID” discloses a cup lid which has only one drinking port. Therefore, it is meaningful to provide a double drinking cup lid as well as a thermos cup with the same.
In order to solve at least one of the above technical problems, the present invention provides a cup lid which includes: a cup lid body including a connection portion for connecting to a cup body and provided with an opening; and a connector mounted at the opening and provided with at least one first mouth, where a second mouth is provided at the opening located outside the first mouth.
The connector is detachably arranged so that the first mouth may be replaced with first mouths of various opening sizes to adapt to different populations and meeting their drinking habits, and the connector is easy to detach and clean to prevent bacterial growth.
Here, the connector is arranged in two manners, the first manner is that the connector is arranged in the opening, and an outer wall of the connector and an inner wall of the opening are connected with each other; and the second mouth is arranged on the connector. That is, the connector includes a wall body that is at least partially adapted to the inner wall of the opening and encloses to form the first mouth, and a first outer wall of the wall body and a first inner wall of the opening enclose to form the second mouth.
The other manner is that the connector is arranged in the opening, and an outer wall of the connector and an inner wall of the opening are connected with each other, so that at least a portion of the outer wall of the connector and at least a portion of the inner wall of the opening enclose to form the second mouth. That is, the connector further includes an annular wall connected with the wall body, and the second mouth is formed between an outer wall of the wall body and an inner wall of the annular wall.
The connector is provided with a slot, and further includes a straw, the straw fits into the slot, and a suction channel of the straw is in communication with the first mouth.
With the technical solution described above, the arrangement of the connector and the straw allows sipping from the first mouth.
The connector may be connected by the following structure: a second groove is provided on the connector, the second groove is axially arranged along the connector, an edge of the opening forms a second protrusion adapted to the second groove, and the second protrusion is embedded in the second groove.
The cup lid further includes a ring sleeve, the connector is arranged in an inner hole of the ring sleeve, the outer wall of the connector is connected with the ring sleeve by an annular body, so that the second groove is formed between the outer wall of the connector and an inner wall of the ring sleeve, and the second protrusion is arranged in an annular shape.
A top end face of the opening is obliquely arranged so that the top end face of the opening has a high face and a low face, the first mouth and the second mouth are respectively located at a position of the high face and at a position of the low face on the opening, and a top end face of the first mouth and a top end face of the second mouth are respectively arranged flush with the high face and the low face of the opening.
The connector may also be connected by the following structure: at least a portion of the outer wall of the connector is connected with at least a portion of the inner wall of the opening by a detachable structure; the detachable structure includes at least one first protrusion and at least one first groove adapted to the at least one first protrusion; the at least one first protrusion and the at least one first groove are respectively arranged on a second inner wall of the opening and a second outer wall of the connector; and the at least one first protrusion is embedded in the at least one first groove.
The cup lid further includes a sealing lid movably connected with the cup lid body, and the sealing lid is provided with a sealing surface for blocking the first mouth and the second mouth. A third sealing surface is formed between the connector and the opening, and the sealing surface includes a first sealing surface which is in contact with the connector and/or the opening to achieve blocking. The sealing surface includes a second sealing surface which is in contact with the opening to achieve blocking.
