Description

TECHNICAL FIELD

[0001] The present application relates to the improvement of paper cups, in particular to the improvement of a new type of rolled edge paper cup. BACKGROUND

[0002] The rolled edge of the conventional paper cup on the market is mostly a round structure, and the fitting area with the cover is small, and after the cover is fitted, a gap is easy to appear, the risk of water leakage is high, and the top round angle of the rolled edge is large, so a large force needs to be applied when the cover is fitted, and the cover is easy to deform and loosen after being fitted. Moreover, the cover and the cup body of the paper cup are only connected by simple fitting, that is, the outer peripheral wall of the cover is connected with the rolled edge of the cup body, and the connection stability is insufficient, so that the cover is easy to fall off during carrying, and the sealing of the liquid in the cup cannot be guaranteed. SUMMARY

[0003] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a new type of rolled edge paper cup.

[0004] In order to solve the above technical problems, the present application adopts the following technical scheme: the new type of rolled edge paper cup comprises a cup body made of paper, and a rolled edge is arranged at the upper end of the cup body, characterized in that: the rolled edge is a long and flat structure, and the rolled edge is matched with the outer wall of the cup barrel, an inner recess is arranged on the cup barrel corresponding to the bottom of the rolled edge, and the bottom of the rolled edge is recessed accordingly; the cup body is provided with a cover, the cover is connected with the inner recess in a matched manner, and the outer peripheral wall of the cover is matched with the outer side surface of the rolled edge.

[0005] A cup plug part is arranged on the cover, the cup plug part is embedded in the cup mouth in a matched manner, a clamping groove is arranged on the peripheral wall of the cup plug part, and the clamping groove is connected with the inner recess in a matched manner.

[0006] The cover is made of plastic material, the cover surface of the cover is concave upward and downward to form the cup plug part, and the peripheral wall of the cup plug part is concave inward to form the clamping groove.

[0007] The bottom of the rolled edge is a round bottom, a closing part is arranged on the outer peripheral wall of the cover, and the closing part is connected with the round bottom in a matched manner.

[0008] An outwardly inclined folded edge is arranged at the lower end of the closing part.

[0009] A heat insulation cup sleeve is arranged on the cup body.

[0010] The upper end of the heat insulation cup sleeve is limited to the bottom of the rolled edge.

[0011] The beneficial effects of this invention are that the improved new type of rolled edge paper cup has a long, flat rolled edge that is narrow in the horizontal direction and long in the vertical direction, with a small rounded corner at the top, requiring less force when closing the lid and making it less prone to deformation after the lid is fitted; moreover, the vertical length is more than twice that of conventional rolled edges, greatly increasing the contact area with the outer peripheral wall of the lid, resulting in a tighter fit and reducing leakage problems at the source; the rounded bottom structure of the rolled edge forms a precise snap-fit ​​with the rim of the lid, and together with the snap-fit ​​between the cup stopper groove and the concave part of the cup body, it achieves double locking and fixing, effectively preventing the lid from loosening, making transportation and carrying safer. Attached Figure Description

[0012] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Fig. 1 This is a schematic diagram of the structure of the present invention.

[0014] Fig. 2 This is an enlarged view of part A of the present invention. Detailed Implementation

[0015] The accompanying drawings illustrate the structure of the present invention, and further details will be described below in conjunction with the drawings. In this embodiment, see the attached drawings. Figs. 1-2 This novel rolled-edge paper cup includes a paper cup body 1, which includes a cup cylinder 11 and a cup bottom. The upper end of the cup body 1 is provided with a rolled edge 2, which is a long and flat structure. The rolled edge 2 fits the outer wall of the cup cylinder 11, so the rolled edge 2 is narrow in the horizontal direction and long in the vertical direction. The bottom of the rolled edge 2 is provided with a concave part 3 on the cup cylinder 11 corresponding to the bottom of the cup cylinder 11. The bottom of the rolled edge 2 is concave accordingly, which supports the concave surface 3 and enhances the strength of the concave part 3. The cup body 1 is provided with a lid 4, which is engaged with the concave part 3. The outer peripheral wall of the lid 4 matches and fits the outer side of the rolled edge 2.

[0016] As a further improvement, the lid 4 is provided with a cup stopper 5, which is fitted into the mouth of the cup. The cup stopper 5 is provided with a groove 6 on its peripheral wall. The groove 6 engages with the recessed part 3 to form a sealing structure, thereby comprehensively improving the sealing performance between the lid 4 and the cup body 1.

[0017] As a further improved specific implementation, the cover 4 is made of plastic, which has good deformation performance, more stable and reliable snap-fit, and is more durable and easier to process and mold. The cover surface of the cover 4 is recessed to form the cup stopper 5, and the peripheral wall of the cup stopper 5 is recessed to form the slot 6.

[0018] As a further improved specific implementation, the bottom of the rolled edge 2 is a round bottom 8, and the outer peripheral wall of the cover 4 is provided with a closing part 7. The closing part 7 is engaged with the round bottom 8 to effectively prevent the cover 4 from falling off and further improve the sealing performance.

[0019] As a further improvement, the lower end of the constricted portion 7 is provided with an outwardly sloping flange 9. The flange 9 serves as a guide for the lid 4 to close the cup, ensuring precise and convenient closure, and also provides a point of force for opening the lid 4, allowing the user to easily pinch the flange 9 and pull open the lid 4.

[0020] As a further improved specific implementation, the cup body 1 is covered with a heat-insulating cup sleeve 10. Preferably, the upper end of the heat-insulating cup sleeve 10 is limited to the bottom of the rolled edge 2, so that the heat-insulating cup sleeve 10 is firmly positioned and does not slide.

[0021] The sealing and leak-proof principle of this invention is as follows: the cup stopper 5 is embedded in the cup mouth to form the first physical seal, the groove 6 and the concave part 3 are engaged, and the closing part 7 and the round bottom 8 of the rolled edge 2 are engaged to form a double engagement and fixation. In addition, the long flat rolled edge 2 is tightly fitted to the large area of ​​the outer peripheral wall of the cap 4. The triple structure works together to effectively block the seepage path of the liquid in the cup and achieve excellent leak-proof effect.

[0022] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
