Description

Paper containers that don't jam Technical Field

[0001] The utility model relates to the field of paper cups, in particular to a paper container that can be stacked without getting stuck. Background Art

[0002] Paper cups, paper bowls, and paper boxes are commonly used in the food service industry. These paper containers are made by mechanically processing and gluing raw paper (white cardboard) made from chemical wood pulp. Due to their safety, hygiene, lightness, and convenience, paper containers are widely used in public places, restaurants, and dining halls. Currently, existing paper containers have tapered walls, with openings larger than their base diameters. For transportation and sale, paper containers are typically stacked into cylindrical shapes.

[0003] Patent 202221351019.7 discloses a paper cup with a stacking support structure. Multiple paper cups are supported by a support base within the inner cup body, thereby preventing deformation caused by mutual pressure after stacking and making it easier to remove the paper cups. However, since the paper cups rely on the support base for support during stacking, and the support base is a step formed by paper, its strength is relatively low and it is prone to collapse and deformation under low pressure. This prevents the paper cups from sliding down due to step deformation and prevents the stacked paper cups from getting stuck. Technical issues

[0004] The main technical problem solved by the utility model is to provide a paper container that can be stacked without getting stuck, so that the container can be easily stacked, the stacking structure has high strength, and the container can be effectively prevented from being deformed after being stacked and causing the container to get stuck. Technical Solutions

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a paper container that can be stacked without getting stuck, including a paper container body and a base located below the body, the body having a conical tubular wall with inclined and contracted side walls, the bottom of the body having a base structure, the base structure is formed by gathering toward the center along the bottom edge of the body to form a step shape, the outer side of the base structure is connected to a limiting ring, the base structure and the limiting ring form a support part, when the paper containers are stacked, the base of the upper paper container is stacked on the base structure of the lower paper container, and the upper paper container is supported by the support part.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below. The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them.

[0024] Refer to Figures 1 to 5 , which illustrate a stackable paper container, typically a paper cup. The container's body 1 features a tapered, converging sidewall. An outer layer 2 is spaced apart from the tapered tubular wall. The outer layer 2 is connected to the body 1 by two hot-melt adhesive rings 3, spaced at intervals. Multiple hot-melt adhesive rings 3 are placed between the body 1 and the outer layer 2, separating them and reducing heat transfer within the body 1, providing both cold and heat insulation.

[0025] The bottom of the main body 1 has a base structure 4, and the base structure 4 is formed into a step shape along the bottom edge of the main body 1 and converges toward the center. The outer side of the base structure 4 is connected to a limiting ring 5, and the inner and outer sides of the base structure 4 are both arc-shaped structures. The limiting ring 5 is tightly attached to the arc-shaped structure, and the limiting ring 5 connects the base structure 4 and the outer layer 2. So that a support portion is formed between the three. The limiting ring 5 is a ring-shaped rubber ring formed by hot melt adhesive. The limiting ring 5 is formed by hot melt adhesive, which can be processed synchronously with the above-mentioned hot melt adhesive ring 3, and the hot melt adhesive has a certain strength after cooling, which can realize the connection between the main body 1 and the outer layer 2, and at the same time play a role in strengthening the support of the base structure 4. As for the hot melt adhesive ring 3 as the limiting ring 5, it not only plays a role in connecting the main body 1 and the outer layer 2, but also plays a supporting role for the base structure 4, and can also limit the paper cups when they are stacked.

[0026] Of course, the use of the limiting ring 5 is a low-cost and easy-to-process embodiment. The limiting ring 5 can also be made of glass, paper or plastic, as long as it has a certain supporting strength, and can be achieved by conventional processes such as bonding and ultrasonic welding.

[0027] The stacking of paper containers causes the base 7 of the upper body 1 to be stacked on the support structure 4, and the support portion is used to support the upper paper container. The base 7 is an outward-expanding base 7 with an outward diameter along the lower direction of the support structure 4. When the paper cups are stacked, the lower end of the base 7 of the upper paper cup is stacked on the upper edge position of the inner side of the support structure 4 of the lower paper cup, thereby supporting the upper paper cup. After multiple paper cups are stacked, the base 7 of the upper paper cup contacts the support structure 4 of the lower paper cup. The limiting ring 5 can increase the supporting strength of the support structure 4, so that the support structure 4 will not deform and collapse due to excessive pressure when in contact with the base 7, thereby ensuring that multiple paper cups can be effectively stacked and formed. At the same time, the base 7 is an outward-expanding, outward-splayed base. This structure increases the strength of the base 7 and prevents the base 7 from sliding into the interior of the support structure 4, causing the paper cups to get stuck.

[0028] The upper end of the body 1 has an inner edge 6 of the cup mouth, which is a straight edge structure. The straight edge structure helps to fit with the cup lid, and the lid is buckled smoothly and tightly without leaking.

[0029] In a test, five products were stacked face down on a table, weights of varying weights were placed on top, and the cups were left there for one minute to test whether they could be removed with one hand. The test results for the paper cups in this application showed that they could still be easily removed after a 10 kg squeeze. However, the paper cups in Patent 202221351019.7 could only be removed with difficulty after a 1 kg squeeze.

[0030] Of course, the paper cups mentioned above can also be replaced with paper boxes, paper bowls, or paper buckets. Hot melt adhesives with a softening temperature above 100°C can be selected, which is suitable for paper containers that need to be heated or for holding high-temperature items.

[0031] Different from the prior art, the paper container of the present invention can be easily stacked without getting stuck, and the stacking structure has high strength, which effectively prevents the container from being deformed and getting stuck after being stacked.

[0032] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
