Description

Technical Field

[0001] This utility model relates to the field of paper cup technology, and in particular to a high-strength anti-slip paper cup. Background Technology

[0002] Paper cups are disposable cups made primarily of paper. They are extremely common in daily life and business settings, and are widely used in beverage sales, conferences, family gatherings, and other occasions.

[0003] Most paper cups in the current technology have a single-layer structure. Because they only have one layer of material, they cannot effectively distribute pressure when subjected to external pressure. This causes excessive stress in some areas of the cup, which can easily lead to deformation of the cup, affecting normal use, and may even cause drinks to spill, causing inconvenience to users. Moreover, the surface of paper cups is generally smooth, and the anti-slip coating alone is not effective enough to meet actual usage needs. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength, non-slip paper cup, which solves the problem that existing paper cups are generally single-layered, have average strength, and poor non-slip performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-strength, non-slip paper cup includes a cup body and a cup bottom, wherein the cup bottom and the bottom of the cup body are bonded together. The cup body is characterized by having an overall frustum-shaped cylindrical structure and a double-layer composite design, including an inner layer of paper and an outer layer of paper. The side of the inner layer of paper close to the outer layer of paper has multiple reinforcing ribs vertically bonded at uniform intervals. The outer surface of the outer layer of paper is pressed with densely packed and regularly arranged circular grooves using a pressing machine. The inner layer of paper and the outer layer of paper are tightly bonded together with a special adhesive.

[0007] Preferably, the top of the cup body is formed by a curling process to create an outward-folded edge.

[0008] Preferably, the rolled edge forms a hollow interlayer, with a plastic ring embedded inside.

[0009] Preferably, the inner paper is completely covered with a waterproof layer on the side facing the inner space of the cup.

[0010] Preferably, the outer paper is coated with a protective coating on the side exposed to the external environment.

[0011] Preferably, the bottom of the cup body is provided with an outwardly protruding anti-slip ring, which is made of rubber.

[0012] This utility model has at least the following beneficial effects:

[0013] The paper cup features a double-layer composite design, with the inner and outer layers connected by multiple vertical reinforcing ribs. This disperses the pressure on the cup, preventing excessive local stress and enhancing the vertical and horizontal strength of the cup, making it more resistant to compression. The horizontal circular grooves not only provide an anti-slip effect but also further strengthen the cup.

[0014] The inner hollow layer of the rolled edge at the very top of the cup body has a plastic ring embedded in it, which has a certain degree of toughness and support, providing extra support for the rolled edge, enhancing the strength and stability of the cup mouth, so that the cup mouth is not easily deformed due to thermal expansion and contraction or external force when filled with hot drinks, while also improving the overall texture of the paper cup.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Reference Figure 1-3 A high-strength anti-slip paper cup includes a cup body 1 and a cup bottom 2, the cup bottom 2 and the bottom of the cup body 1 are bonded together. The cup body 1 has an overall frustum cylindrical structure. The cup body 1 adopts a double-layer composite design, including an inner layer paper 11 and an outer layer paper 13. On the side of the inner layer paper 11 close to the outer layer paper 13, multiple reinforcing ribs 12 are vertically pasted at uniform intervals. The reinforcing ribs 12 are made of polypropylene plastic. The outer surface of the outer layer paper 13 is pressed with dense and regularly arranged circular grooves 14 by a pressing machine. The inner layer paper 11 and the outer layer paper 13 are tightly bonded together by a special adhesive, wherein the adhesive is a water-based polyurethane adhesive.

[0023] The cup body 1 is ergonomically shaped like a frustum, making it easy to grip. In its double-layer composite design, the inner paper layer 11 and the outer paper layer 13 are connected by multiple vertical reinforcing ribs 12. These ribs 12 distribute the pressure on the cup body 1, preventing excessive localized stress. The circular grooves 14 on the outer surface of the outer paper layer 13 increase friction with contact surfaces, providing an anti-slip effect. The inner and outer paper layers 11 are tightly bonded together with a special adhesive, ensuring the stability of the overall structure. The vertical reinforcing ribs 12 enhance the vertical and horizontal strength of the cup body 1, making it more resistant to compression.

[0024] Furthermore, the top of the cup body 1 is formed by a curling process to create an outward-folding rolled edge 15.

[0025] Furthermore, a hollow interlayer is formed inside the rolled edge 15, with a plastic ring 3 embedded within it. The plastic ring 3 has a certain degree of toughness and support, providing additional support for the rolled edge 15, further enhancing the strength and stability of the cup rim, so that the cup rim is not easily deformed due to thermal expansion and contraction or external forces when filled with hot drinks. At the same time, the presence of the plastic ring 3 enhances the overall texture of the paper cup.

[0026] Furthermore, the inner paper 11 is completely covered with a waterproof layer on the side facing the inner space of the cup. Water or other liquids cannot penetrate the inner layer after contacting this waterproof layer, thus achieving a waterproof effect, effectively preventing liquid leakage, ensuring the paper cup's holding function, and extending its service life. To prevent the paper cup from softening or deforming due to liquid leakage, affecting its use, the waterproof layer uses a water-based acrylic emulsion. This material, after being coated on the surface of the inner paper 11, forms a firmly adhering coating, effectively preventing leakage. It not only has excellent adhesion, heat resistance, and media resistance, but also better tolerance to hot beverages.

[0027] Furthermore, the outer paper 13, on the side exposed to the external environment, is coated with a protective coating. This water-based coating enhances the paper cup's weather resistance, ensuring it maintains a good appearance and performance under various environmental conditions. This extends the paper cup's storage time and reduces the rate of damage caused by environmental factors.

[0028] Furthermore, the bottom of the cup body 1 is provided with an outwardly protruding anti-slip ring 4, which is made of rubber. When the paper cup is placed on a flat surface, the anti-slip ring 4 is in close contact with the surface, increasing the friction between the paper cup and the surface and preventing the paper cup from sliding. At the same time, the rubber anti-slip ring 4 can also play a certain role in waterproofing, and can also provide good protection when there are water stains on the table.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
