Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a container cover which is easy to open and close. Background Art

[0002] In the patent document "CN213075285U", the technical solution adopted for sealing the suction hole is that the arc-shaped protrusion on the sealing column and the arc-shaped groove in the suction hole cooperate with each other; however, since the material of the cup cover is PP plastic parts, and the PP plastic parts have a molding shrinkage rate, which is between 1.5% and 2.2%, it is necessary to consider the shrinkage rate during the production process to ensure the size matching, but there are many factors that affect the shrinkage rate, and it is impossible to strictly control it during processing, and the arc-shaped protrusion and the arc-shaped groove are both small-sized parts, which are more easily affected; therefore, the finished products of the arc-shaped protrusion and the arc-shaped groove are either too tight and difficult to open when matched, or too loose and vibrate open during transportation. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a container cover.

[0037] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0038] Embodiment 1:

[0039] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a container cover, comprising:

[0040] A cover body 1; a suction hole 2 disposed on the cover body; and a suction hole cover 3 attached to the cover body, which is movable between at least an open position and a closed position.

[0041] The suction hole cover 3 has a plunger 31 suitable for closing the suction hole 2 at the closing position.

[0042] At least two vertical ribs 32 are arranged at intervals in the circumferential direction of the plunger 31, and the vertical ribs 32 extend along the axial direction of the plunger 31;

[0043] Due to the interference fit between the vertical rib 32 and the suction hole 2 , the plunger 31 can be stably held in the suction hole 2 , and the plunger 31 can be easily pulled out of the suction hole 2 .

[0044] Since the vertical convex ribs are arranged at intervals, the contact area between the vertical convex ribs and the side wall of the suction hole is limited, which can ensure stable insertion between the plunger and the suction hole to close the suction hole, while at the same time reducing friction to facilitate opening the suction hole.

[0045] The number of vertical ribs is not limited; see Figure 1 It is preferred to set a vertical rib at each of the four equally divided positions of the plunger in the circumferential direction, so that the plunger in the suction hole is subjected to a more uniform force and can be stable during transportation.

[0046] In some embodiments, the vertical rib 32 is integrally formed with the plunger to facilitate manufacturing.

[0047] In some embodiments, see Figure 2The suction hole includes: a first hole portion 21 defined by a first diameter; and a second hole portion 22 defined by a second diameter greater than the first diameter; wherein the second hole portion 22 is arranged below the first hole portion 21 to avoid the lower portion of the plunger 31, so that the operator can easily insert and remove the plunger 31. The inner wall of the first hole portion 21 cooperates with the vertical rib 32, while the inner wall of the second hole portion 22 has no cooperation relationship with the vertical rib 32 (see Figure 3 ), which can keep the plunger 31 plugged in the suction hole and facilitate the withdrawal of the plunger 31.

[0048] In some embodiments, the thickness D of the vertical convex rib is in the range of 1.0 mm ≥ D ≥ 0.10 mm. Preferably, the thickness D of the vertical convex rib is 0.50 mm. Under this size, the gap between the suction hole and the plunger can be flexibly adjusted. When the size of the vertical convex rib is not uniform, the impact is minimal and the matching is most appropriate.

[0049] In some embodiments, the plunger 31 is a hollow columnar plunger, which saves materials and reduces costs.

[0050] In some embodiments, the suction hole cover has an operating portion 33 for the user to perform an opening operation, and a avoidance groove suitable for avoiding the operator's hand is formed on the cover body at a position corresponding to the operating portion 33. The use of the avoidance groove 4 facilitates the opening of the suction hole cover, and the suction hole cover can be opened without additional shaping. Otherwise, the edge of the suction hole cover needs to be slightly tilted upwards to facilitate opening, but this is easy to be accidentally opened during transportation. Therefore, the structure of the avoidance groove 4 can not only facilitate opening, but also has a protective effect on the closing of the suction hole cover.

[0051] In some embodiments, the escape groove 4 has an inclined escape groove side wall 41, so that the projection area of ​​the opening on the escape groove 4 is larger than the area of ​​the bottom surface. This facilitates operation. When the plunger needs to be opened, the finger is inserted into the bottom of the operating part 33 on the suction hole cover along the escape groove side wall 41, and the suction hole can be directly opened by pulling the finger upward.

[0052] In some embodiments, the suction hole cover is hinged on the side wall of the cover body 1. This arrangement has a simple structure and is easy to manufacture.

[0053] In some embodiments, a sealing ring made of food-grade rubber is provided on the plunger, and when the plunger is inserted into the suction hole, the sealing ring elastically contacts the body. After adding this structure, an effective seal can be achieved between the plunger and the suction hole.

[0054] The cover body of the utility model is easy to use. Since vertical ribs are arranged in the circumferential direction of the plunger, the vertical ribs can adjust the matching size between the suction hole and the plunger, so that the matching of the plunger and the suction hole is minimally affected by the shrinkage rate. And since the contact area between the ribs and the inner wall of the suction hole is limited, it is easy to open and convenient to use.

[0055] See also Figure 4 In the present invention, a beverage cup is also provided, comprising a cup body 5 and a cover body 1, wherein the cover body 1 is any of the container covers described above.

[0056] The beverage cup with the cup container cover is easy to open and safe and stable during transportation.

[0057] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
