Example one

As shown in fig. 1-3, in an embodiment of the present invention, a cup lid is provided, which includes a lid body 1, and the lid body 1 is made of a plastic material, such as PP polypropylene material. The edge of the cover body 1 is bent downwards to form an annular surrounding edge 2, the bottom surface of the cover body 1 is provided with a sealing ring 3, the sealing ring 3 and the surrounding edge 2 are arranged coaxially, and the inner diameter of the surrounding edge 2 is larger than the outer diameter of the sealing ring 3; the inner wall of the surrounding edge 2 is provided with a rib 4, the rib 4 extends along the circumferential direction of the surrounding edge 2, the rib 4 comprises a first inclined surface 41 and a second inclined surface 42, the edge of the first inclined surface 41 inclines downwards, and the edge of the second inclined surface 42 inclines upwards and is connected with the edge of the first inclined surface 41.

The embodiment discloses a bowl cover, it is through design surrounding edge 2 and sealing ring 3 on lid 1, goes up the cup edge of cup 6 and can block into in the clearance between surrounding edge 2 and the sealing ring 3, so, after going up lid 1 lock at the cup edge of last cup 6, surrounding edge 2 and sealing ring 3 can press from both sides tightly the cup edge of going up cup 6 jointly to firmly lock lid 1 on last cup 6, improved leakproofness and compactness.

In the present embodiment, the top surface of the cover body 1 is provided with a boss 5, the top surface of the boss 5 is recessed downward to form a groove 51, and the groove 51 is arranged coaxially with the sealing ring 3. Through the top design boss 5 at lid 1 to design recessed recess 51 on boss 5, with lid 1 lock back on last cup 6, the lower cup 7 of another packing cup can be placed in recess 51, thereby can pile up a plurality of packing cups and put, and be difficult for falling the cup when stacking, it is neat pleasing to the eye to pile up, does benefit to the vanning and puts, simultaneously, has also reduced the occupation of land space when stacking.

In the present embodiment, the boss 5 is arranged coaxially with the cover 1, and the cross section of the sidewall of the boss 5 is in a convex arc shape. The structural design of boss 5 can increase the bearing capacity of lid 1, strengthens the holistic structural strength of lid 1 to when piling up a plurality of packing cups, avoid lid 1 to take place to warp or break effectively.

In this embodiment, the depth of the groove 51 is greater than the height of the boss 5. By deepening the groove 51, the probability of toppling over of the packaging cups can be effectively reduced when the packaging cups are stacked.

Example two

In the present embodiment, the components in the first embodiment are included, the working principle is the same, and with reference to fig. 1, 4 to 7, the present invention further provides a packaging cup, which includes the cup cover of the first embodiment, and includes an upper cup body 6 and a lower cup body 7 that are coaxially arranged, the upper cup body 6 is connected and communicated with the lower cup body 7, the upper cup body 6 and the lower cup body 7 are in an integral structure, and are made of plastic materials, such as PP polypropylene materials. The inner diameter of the cup mouth of the upper cup body 6 is larger than the outer diameter of the sealing ring 3, and the inner diameter of the upper cup body 6 is gradually reduced from top to bottom; the cup edge of the upper cup body 6 extends outwards to form a bulge 8, the outer wall of the bulge 8 comprises an abutting surface 81, the bottom of the abutting surface 81 inclines towards the axial direction of the upper cup body 6, and the abutting surface 81 is matched with the first inclined surface 41.

The embodiment discloses a packaging cup, after the cover body 1 is buckled, the cup edge of the upper cup body 6 is clamped into the gap between the surrounding edge 2 and the sealing ring 3, and the inclined abutting surface 81 and the first inclined surface 41 are matched with each other, so that the convex edge 4 can be prevented from being separated from the bulge 8, and the phenomenon that the cover body 1 and the upper cup body 6 fall off is effectively avoided.

Simultaneously, when lock lid 1, because the internal diameter top-down of going up cup 6 reduces gradually, sealing ring 3 can paste the inner wall of cup 6 gradually to certain deformation takes place, after the lock, the outer wall part of sealing ring 3 or whole hug closely on the inner wall of last cup 6, sealing ring 3 just can seal up cup 6 on the lock. In the process, the sealing ring 3 can also push against the wall of the buckled cup body, so that the abutting surface 81 is tightly attached to the first inclined surface 41, and the looseness between the cover body 1 and the upper cup body 6 is further avoided.

Through design sealing ring 3 and bead 4 on lid 1 to design arch 8 on the cup edge of last cup 6, guaranteed that lid 1 and last cup 6 between can closely the lock, not only promoted this packing cup's sealing performance, simultaneously, also avoided the condition that lid 1 drops to take place.

In the embodiment, in order to improve the bearing capacity of the upper cup body 6 and enhance the structural strength of the upper cup body 6, a step 9 is formed at the joint of the upper cup body 6 and the lower cup body 7, and the minimum inner diameter of the upper cup body 6 is larger than the inner diameter of the cup opening of the lower cup body 7.

In this embodiment, the outer wall of the projection 8 includes a sliding surface 82, the sliding surface 82 is in a convex arc shape, and the bottom of the sliding surface 82 is connected with the top of the abutting surface 81. When the lid 1 is engaged, the second inclined surface 42 first contacts the sliding surface 82, and during the process of pressing down the lid 1, the second inclined surface 42 slides along the arc-shaped sliding surface 82 until the second inclined surface 42 completely passes through the sliding surface 82, and the first inclined surface 41 cooperates with the abutting surface 81 to firmly clamp the lid 1 on the upper cup 6. The arc sliding surface 82 is designed on the protrusion 8, so that the second inclined surface 42 of the rib 4 can move on the protrusion 8, and the cap 1 can be conveniently buckled on the upper cup body 6.

In this embodiment, the external diameter of lower cup 7 bottom of cup is less than recess 51's internal diameter, so, lower cup 7's bottom of cup can be placed in recess 51 to can pile up a plurality of packing cups and put, and, be difficult for falling the cup when stacking, it is neat pleasing to the eye to pile up, does benefit to the vanning, simultaneously, has also reduced the occupation of land space when stacking.

In the description of the present invention, numerous specific details are set forth. It is understood, however, that embodiments of the utility model may be practiced without these specific details. In some instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
