Definitions
- the utility model belongs to the technical field of cup lids, in particular to a negative angle pulp moulding cup cover.
- the pulp cup lid which typically has an open top, is then capped to the top of the pulp cup.
- the seal between the existing cup lid and the cup is generally provided with a sealing structure at the top of the cup, which avoids leakage between the two.
- the inventors have devised a sealing structure in which the inner wall of the cup cover is convex, which not only improves the sealing property but also improves the cup lid and the cup. Preventive performance between.
- the improvement is improved, the above-mentioned improvement has at least the following defects: the cup and the lid are repeatedly disassembled, and the cup cover diameter is invisibly enlarged, and the sealing is deteriorated between the two. .
- An object of the present invention is to provide a negative angle pulp molded cup cover capable of improving sealability and structural strength in view of the above problems.
- the present invention adopts the following technical solution: the negative angle pulp molding cup cover, the cup cover is made of pulp, and includes a top portion and a side portion connected to the top edge, the side inner wall having the inner portion
- the conical surface, the inner conical surface forms an angle of less than 90° with the lower surface of the top and the inner diameter of the inner conical surface gradually decreases from top to bottom.
- the side walls are of equal thickness.
- the side wall thickness gradually increases from the top to the bottom.
- the side outer wall has an outer conical surface that is symmetrical with the inner conical surface.
- the inner conical surface axis line coincides with the axial line of the outer conical surface.
- the outer edge of the top lower surface is provided with a ring-shaped sealing groove for the cup opening of the cup.
- the rib is parallel to the top.
- the ribs are disposed obliquely downwardly outward.
- the inner wall of the lower end of the inner conical surface is provided with an inner convex annular portion.
- the inner convex annular portion has a circular arc convex surface.
- the inner convex annular portion has a thickness smaller than the thickness of the tapered cylindrical portion.
- the side portion and the inner convex annular portion are integrally formed.
- the inner conical surface of the design cooperates with the convex ring structure at the upper end of the cup, which can achieve the sealing between the two and the reinforcement of the connection structure, avoiding falling off and leaking, and the design is more reasonable and the structure is more reliable and stable.
- the structure of the annular sealing groove surface combined with the inner convex annular portion can further improve the structural strength and the firmness of the joint fit, and the sealing property.
- Figure 1 is a schematic view of the structure provided by the present invention.
- FIG. 2 is a schematic view showing the structure of the inner annular portion provided by the present invention.
- FIG 3 is a schematic structural view of a fourth embodiment provided by the present invention.
- FIG. 4 is a schematic view showing the vertical state of the side outer wall provided by the present invention.
- Fig. 5 is a schematic view showing the structure of the side outer wall of the present invention which is inclined outward.
- Figure 6 is a schematic view showing the state of the utility model after being engaged with the cup.
- the present negative angle pulp molding cup cover is made of pulp comprising a top portion 1 and a side portion 2 joined to the edge of the top portion 1, the top portion 1 and the side portion 2 being formed by pulp injection molding. .
- the inner wall of the side portion 2 has an inner conical surface 31, the inner conical surface 31 forms an angle of less than 90° with the lower surface of the top portion 1 and the inner diameter of the inner conical surface 31 gradually decreases from top to bottom, which cooperates with the convexity of the upper end of the cup.
- the ring structure can realize the sealing between the two and the reinforcement of the connecting structure, avoiding falling off and leaking, and the design is more reasonable and the structure is more reliable and stable.
- the optimization scheme gradually increases the thickness of the side portion 2 from top to bottom.
- a ring seal groove 11 is provided on the outer edge of the lower surface of the top portion 1 for the cup opening of the cup.
- the ring seal groove 11 can further improve the sealing property.
- the rib 4 is parallel to the top 1.
- an inner annular portion 33 is provided on the inner wall of the lower end of the inner conical surface 31.
- the inner convex annular portion 33 can further improve the sealing property.
- the inner convex annular portion 33 has a circular arc convex surface 331.
- the side portion 2 and the inner convex annular portion 33 are integrally formed.
- annular sealing groove 11 is designed to form a seal with the cup opening at the top of the cup, which can further enhance the sealing of the joint.
- the structure and principle of the first embodiment are basically the same as those of the first embodiment, and the details are not described herein.
- the difference is that the side portions 2 have the same wall thickness.
- the structure and the principle of the first embodiment are basically the same as those of the first embodiment, and the details are not described herein.
- the difference is that the rib 4 is inclined downward and outward.
- the structure and principle of the first embodiment are basically the same as those of the first embodiment, and the details are not described herein. The difference is that the lower portion of the side portion 3 is provided with the annular portion 5.
