Technical Field

[0001] The utility model relates to the technical field of disposable beverage cups, in particular to an anti-theft and anti-leakage paper beverage cup. Background Art

[0002] In recent years, the takeaway food and beverage business has become increasingly prosperous. During the delivery of takeaways, it is common for the beverage in the cup to be maliciously taken out, or for other unknown substances to be added to deliberately target takeaway merchants. At the same time, the beverage may spill during transportation or when the customer is drinking. Therefore, various sealed disposable beverage cups have emerged on the market, or seals are pasted on paper cups. However, in the field of disposable paper beverage cups for takeaways, there is currently no paper cup that can achieve simple and effective anti-theft opening and anti-leakage without self-sealing tools.

[0003] The cup bodies of existing paper cups are generally made of paper, and the cup lids are made of paper, plastic, etc. These cup bodies and cup lids are directly opened and closed, without anti-theft opening and anti-leakage functions. The present invention solves this problem. Summary of the Invention

[0004] To overcome the above technical problems existing in the prior art, the utility model provides an anti-theft and anti-leakage paper beverage cup.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An anti-theft and anti-leakage paper beverage cup, comprising a paper cup body and a cup lid that is buckled with the cup body. The side wall of the paper cup body is inclined downward and outward relative to the central vertical line of the cup body. The upper edge of the paper cup body is provided with an outward-turned curled edge, and the cross-section of the curled edge is in a superior arc shape, and the arc top that protrudes outward is roughly in the middle position of the height. The cup lid includes an integrally formed top surface and a border groove. The inner side wall and the outer side wall of the border groove are both perpendicular to the top surface. Among them, the outer side wall of the border groove surrounds the outside of the curled edge, the inner side wall of the border groove surrounds the inner side of the upper edge of the paper cup body, and the space between the outer side wall and the inner side wall of the border groove forms a sealed embedding groove for accommodating the curled edge; an inclined surface that bulges upward relative to the outer side wall of the border groove is provided on the inner side of the outer side wall of the border groove, and a protruding rib is connected to the bottom of the inclined surface. The rib protrudes inward based on the outer side wall of the border groove. When the paper cup body and the cup lid are buckled, the rib and the inclined surface press the arc top of the curled edge to elastically deform and embed into the curled edge; it is characterized in that:

[0007] An inclined surface that inclines inward from top to bottom is provided on the outer side of the inner side wall of the border groove, and the inclination angle of the inclined surface is less than or equal to the inclination angle of the side wall of the paper cup body. When the paper cup body and the cup lid are buckled, the inclined surface is pressed into the inner side of the upper edge of the paper cup body and the inclined surface is closely fitted with the upper edge of the paper cup body;

[0008] On the outer side wall of the border groove and at the bottom of the clamping rib, there are at least two correspondingly arranged slots. At each slot, there is a swingable hook-shaped piece. The front end of the hook-shaped piece is small and the rear end is large, and the rear end is arc-shaped to form a clamping groove for clamping on the curled edge of the upper edge of the paper cup body. The bottom of the inner wall of the clamping groove has a triangular hook head facing the side wall of the paper cup body; the connection between the hook-shaped piece and the bottom of the clamping rib is a point connection that can be easily broken. When the paper body is tightly sealed with the cup lid, the hook-shaped piece can be bent inward relative to the outer side wall of the border groove and then pushed into the curled edge of the upper edge of the paper cup body, and the triangular hook head hooks the inner side of the curled edge to realize the self-locking of the paper cup body and the cup lid.

[0009] Furthermore, the distance between the lower outer sides of the inner side walls of the border groove is less than or equal to the distance between the inner sides of the upper ends of the paper cup body, which is beneficial for the introduction of the lid during closing.

[0010] Furthermore, there are three slots on the outer side wall of the border groove and at the bottom of the clamping rib, and the three slots are respectively located at the trisection points of the outer side wall of the border groove.

[0011] Furthermore, a tabletop extends inward from the inner side of the top surface. There is a protruding limiting step on the tabletop, and the limiting step is arranged around the bottom end of the paper cup body and is used to limit the horizontal displacement of the paper cup body stacked above the cup lid.

[0012] Furthermore, the distance between the top of the clamping rib and the top surface is greater than 1 / 2 of the curled edge height and less than 9 / 10 of the curled edge height.

[0013] Furthermore, the distance between the top of the clamping rib and the top surface is greater than 1 / 2 of the curled edge height and less than 4 / 5 of the curled edge height.

[0014] Furthermore, the inner diameter of the lower end of the sealing groove is greater than the outer diameter of the upper end of the sealing groove, which is beneficial for the stacking of cup lids.

[0015] Furthermore, the top of the clamping rib is higher than the protruding height of the bottom of the inclined surface; the distance between the lower part of the inclined surface and the side wall of the paper cup body is less than the distance between the arc top and the side wall of the paper cup body; the distance between the end of the clamping rib and the side wall of the paper cup body is less than the distance between the arc top and the side wall of the paper cup body.

[0016] Furthermore, the cup lid is prepared by integrally molding with a degradable material or plastic.

[0017] Compared with the prior art, the beneficial effects of the present utility model are reflected in:

[0018] (1) Prevent the beverage cup from being opened midway: After the cup lid is tightly sealed with the paper cup lid, push this hook-shaped piece into the annular groove of the paper cup. Since this hook-shaped piece is at the slot of the cup lid, after it is pushed into the groove of the cup body, both its left and right sides are covered by the cup lid. Unless a special tool is used, it is generally impossible to open the cup lid by hand. When the cup lid is forcibly opened, the connection point between the cup lid and the hook-shaped piece will be broken, and it can be easily detected that someone has opened the paper cup.

[0019] (2) Due to the anti-theft hook-shaped piece, when the hook-shaped piece is pushed into the curled edge of the paper cup body, in addition to having the function of preventing unauthorized opening, it also has the function of tightly locking and self-locking the paper lid and the paper cup, further increasing the tightness of the paper cup and further reducing the possibility of leakage. At the same time, it avoids leakage when pouring.

[0020] (3) By setting a tabletop and a limiting step at the top of the frame, it avoids the situation where multiple paper cups slip and tip over during transportation when multiple paper cups are stacked.

[0021] (4) Due to the close fastening of the cup lid and the paper cup, the overall strength of the paper cup can be effectively increased. BRIEF DESCRIPTION OF THE DRAWINGS
