Description

Technical Field

[0001] The utility model mainly relates to the technical field of pulp cups, in particular to a high-strength pulp molded cup. Background Art

[0002] Pulp is a clean raw material based on wood, renewable and biodegradable. Since it can be recycled and remanufactured, it conforms to the energy-saving trend of environmental protection and reuse, so it has received widespread attention and favor in the market. Pulp molded cups are formed by placing pulp in a special mold. The existing pulp molded cups lack reinforcement structures around the cup walls, and are limited by the low strength of the pulp material itself. When receiving external pressure, the cup wall will be squeezed and deformed, making the pulp molded cup unusable and less durable. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of the utility model is to provide a high-strength pulp molded cup, by respectively arranging a top ring and a bottom ring that fit the cup wall at the top and bottom of the cup wall, so as to achieve circumferential reinforcement of the cup wall, and by arranging reinforcement ribs and reinforcement rings between the top rings, the cup wall is reinforced axially and radially, thereby improving the overall strength of the pulp cup wall.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-strength pulp molded cup, comprising a cup bottom, a cup wall is arranged on the outer periphery of the cup bottom, a bottom ring is sleeved on the cup bottom, the bottom ring is fixedly connected to the cup wall, a top ring is arranged on the cup wall, a plurality of reinforcing ribs are arranged circumferentially between the top ring and the bottom ring, any one of the reinforcing ribs penetrates the cup wall and is fixedly connected to the penetrated end of the cup wall, a reinforcing ring is axially arranged between the top ring and the bottom ring, and the reinforcing ribs are fixedly connected to the reinforcing ring.

[0005] Preferably, the cup wall comprises an inner pulp layer, an insulating layer and an outer pulp layer, wherein the inner pulp layer is located on the inner side of the insulating layer and the outer pulp layer is located on the outer side of the insulating layer, and the insulating layer reduces heat conduction of the cup wall.

[0006] Furthermore, the thermal insulation layer is polyurethane foam.

[0007] Preferably, a plurality of anti-skid grooves are evenly distributed on the outer surface of the reinforcement ring, and the friction force of the surface of the reinforcement ring is improved by the anti-skid grooves.

[0008] Preferably, the number of the reinforcing ribs is six, the six reinforcing ribs are evenly distributed in a circular array, any one of the reinforcing ribs is a cylindrical structure, the reinforcing ribs are respectively fixedly connected to the bottom of the top ring and the top of the bottom ring, and the cup wall is axially reinforced by the six evenly distributed reinforcing ribs.

[0009] Preferably, the bottom ring, top ring, reinforcement ring and reinforcement ribs are made of the same material, which is food-grade silicone.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] By respectively arranging a top ring and a bottom ring that fit with the cup wall at the top and bottom of the cup wall, and arranging the cup bottom on the inner diameter of the bottom ring, the cup wall and the cup bottom are fixed in the circumferential direction. When subjected to radial external pressure, the top ring and the bottom ring are stressed to protect the cup wall and the cup bottom from deformation. By arranging reinforcing ribs circumferentially between the top rings and reinforcing rings radially, the cup wall is reinforced axially and radially. The top ring, the bottom ring, the reinforcing ribs and the reinforcing rings are fixedly connected to each other, and the cup wall structure is stable and not easily deformed.

[0022] like Figures 1 to 5As shown, a high-strength pulp molded cup includes a cup bottom 6, which is a circular pulp board. A cup wall 2 is arranged on the circumference of the cup bottom 6. A bottom ring 1 is sleeved on the cup bottom 6. The bottom ring 1 is fixedly connected to the cup wall 2. A top ring 3 is arranged on the cup wall 2. The diameter of the top ring 3 is 1.5 times that of the bottom ring 1. The internal space of the cup wall 2 gradually decreases from top to bottom, thereby increasing the internal volume while keeping the occupied desktop space unchanged.

[0023] Six reinforcing ribs 5 are arranged along the circumferential direction between the top ring 3 and the bottom ring 1, and the six reinforcing ribs 5 are evenly distributed in a circular array. Any one of the reinforcing ribs 5 is a cylindrical structure, and the reinforcing ribs 5 are respectively fixedly connected to the bottom of the top ring 3 and the top of the bottom ring 1, and any one of the reinforcing ribs 5 penetrates the cup wall 2 and is fixedly connected to the penetrated end of the cup wall 2. A reinforcing ring 4 is arranged between the top ring 3 and the bottom ring 1 at the axial center position of the cup wall 2, and the reinforcing ring 4 surrounds the surface of the cup wall 2, and the reinforcing ribs 5 are fixedly connected to the reinforcing ring 4.

[0024] The cup wall 2 is a laminated structure that is symmetrical inside and outside. The cup wall 2 includes an inner pulp layer 21, an insulation layer 22 and an outer pulp layer 23. The inner pulp layer 21 is located on the inner side of the insulation layer 22, and the outer pulp layer 23 is located on the outer side of the insulation layer 22. The inner pulp layer 21 and the outer pulp layer 23 have the same thickness. The insulation layer is polyurethane foam, which is a new type of synthetic material with thermal insulation and waterproof functions. It has low thermal conductivity and high strength after curing and is not easy to crack. A connection port that fits the reinforcement rib 5 is formed at the contact position between the cup wall 2 and the reinforcement rib 5, so that the reinforcement rib 5 penetrates the cup wall 2 and is connected and fixed.

[0025] A plurality of anti-skid grooves 41 are equidistantly distributed along the circumferential direction on the circular outer surface of the reinforcement ring 4 . The anti-skid grooves 41 are square grooves, which make the surface of the reinforcement ring 4 uneven and increase the friction when the finger contacts the surface of the reinforcement ring 4 .

[0026] The bottom ring 1, top ring 3, reinforcement ring 4 and reinforcement rib 5 are made of the same material, which is food-grade silicone. The food-grade silicone is an inorganic polymer colloid material formed by condensation of silicic acid. It is soft, elastic, not easy to deform, has high tear strength, and can be in direct contact with food after sterilization.

[0027] The implementation principle of Example 1 of the present application is as follows: when the product is in use, the beverage is poured into the cavity formed by the cup wall 2 and the cup bottom 6, and the beverage is isolated by the inner pulp layer 21 and does not leak out. The beverage temperature is isolated after being thermally conducted along the inner pulp layer 21 to the heat insulation layer 22, thereby reducing the conduction effect of the beverage temperature sensed on the surface of the outer pulp layer 23. When the product is squeezed and pulled by an axial external force, the reinforcement ribs 5 are stressed, and the cup wall 2 is protected between the bottom ring 1 and the top ring 3 at both ends of the reinforcement ribs 5, and is not easily deformed axially. When the product is squeezed and pulled by a radial external force, the bottom ring 1, the top ring 3 and the reinforcement ring 4 arranged around the outer wall of the cup wall 2 are stressed, and the cup wall 2 is protected and not easily deformed radially, and the structure has high strength and durability.

[0028] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the basic features of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
