Thereby not only improving the structural strength of the cup body, but also reducing the cost of the heat insulation structure and achieving the best heat insulation effect.

Description

Structural Improvement of Paper Cup Container

technical field

The invention belongs to the field of paper containers, in particular to the invention of improving the cup body structure of paper cups.

Background technique

At present, the common types of disposable cups on the market can be divided into plastic and paper. With the improvement of people's environmental protection awareness, plastic cups have gradually been replaced by paper cups. The structure of a common paper cup is shown in Figure 1. It mainly has a container (10) that is wide at the top and narrow at the bottom. There is an opening (11) on the top for liquid to be injected and flowed out. The inner surface of the container (10) is coated with a layer of waterproof The film (20) is used to prevent the liquid in the container (10) from soaking the entire paper cup, causing the paper cup to be soft and deformed. However, because the heat-resistant temperature of the paper cup is limited, when the paper cup is filled with hot drinks, it is easy for the user to hold it. The case of being scalded. Later, some people invented paper cups with heat insulation effect one after another. One of them is covered with an outer cover board with heat insulation effect on the outer edge of the container. The outer cover board is preferably made of corrugated paper. Not only the manufacturing cost is high, but also the heat insulation effect is not good. Ideal, so there is a need for improvement.

In view of this, the inventor has made in-depth discussions on the above-mentioned conventional creation problems, and actively sought solutions through years of experience in R&D and manufacturing in related industries. After long-term hard research and development, he finally successfully developed the present invention. The structural improvement of the paper cup container is to improve the problem of customary creation.

Contents of the invention

The main purpose of the present invention is to provide a structural improvement of a paper cup container, which not only makes the paper cup have better structural strength, but also has an excellent heat insulation effect when used to hold high-temperature liquids, so as to improve the quality of use and function.

In order to achieve the above-mentioned purpose of the invention, the present invention consists of a cup body, a cup sleeve, and a glued layer. The cup sleeve is made of a cardboard bonded and covered on the outer edge of the cup for heat insulation. The cup system is formed by folding paper, and has a cup body structure with several concave sides and flange sides interlaced at intervals, and the top edge of each concave side is folded outward to form a beveled side, making the cup mouth appear circular shape of the structure. Secondly, the adhesive layer is formed on the bottom of the cup body and the outer edge of the beveled edge by using plastic injection technology and in-mold molding technology. In this way, using the wavy structure of the cup, with the design of the beveled edge, and the assembly of the cup sleeve, not only can the structural strength of the cup be improved, but also the heat insulation effect can be improved, and it can also be convenient for the user. Drinking, enhance the use value and function of paper cups.

For this reason, the present invention provides a structural improvement of a paper cup container, which includes a cup body, the cup system is folded from paper, and has a cup body structure with a number of concave sides and flange sides interlaced, wherein each of the concave sides of the cup body The top edge is folded outward to form a beveled edge, so that the mouth of the cup presents a circular structure, and a glued layer is formed on the outer edge of the beveled edge of the cup body.

Regarding the technology, means and effects used in the present invention, a preferred embodiment will be described in detail in conjunction with the drawings. It is believed that the above-mentioned purpose, structure and characteristics of the present invention can be gained a deep and specific understanding. .

Detailed ways

Please refer to Figs. 2 to 6, the present invention is composed of a cup body (30), an adhesive layer (40), and a cup cover (50), wherein:

The cup body (30) is a hollow tubular structure folded by paper material, and its edge is composed of several interlaced concave sides (31) and flange sides (32). (32) is a polygonal structure, and the long distance between the inner wall surfaces of each of the concave sides (31) is greater than the distance between the vertices of two adjacent flange sides (32). Simultaneously, the top edge of each of the sunken edges (31) is turned outwards to form a beveled edge (33),

Each of the beveled sides (33) is an oblique structure from the inside to the outside that is low on the inside and high on the outside, so that its outer edge and the flange (32) are on the same horizontal plane, so that its cup mouth presents a ring-shaped structure.

The adhesive layer (40) is a decomposable plastic material, which can be integrally formed on the bottom of the cup body (30) and the outer edges of the beveled sides (33) by using in-mold over-injection molding technology . It is further illustrated that the paper material of the cup body (30) of the present invention has a waterproof structure, that is, its outer edge is covered with a layer of adhesive film (not shown in the figure), so the adhesive layer (40) can be integrally formed on the The outer edge of the cup body (30).

Based on the above, it is added that when the paper material is not folded into a cup shape, a tangent line (321) of an appropriate length is cut along the axial direction of the cup body (30) at the top corresponding to each flange edge (32), and at the same time Corresponding to each of the beveled sides (33) located at the appropriate center of the outer edge, a V-shaped slit (331) is provided to facilitate the forming of the glued layer (40).

The cup cover (50) is a sheet of paper surrounding an object corresponding to the shape of the cup body (30), covering the outer edge of the cup body (30) as an auxiliary heat-insulating structure for the cup body (30).

In addition, as shown in Figure 7, the cup body (30) of the present invention can also be provided with a cup bottom (34) at the bottom, and the edge of the cup bottom (34) forms a cardboard corresponding to the concave-convex edge of the cup body (30), which can make The adhesive layer (40) is bonded and formed at the joint outer edge of the cup body (30) and the cup bottom (34), and presents a different design.

Accordingly, with the above-mentioned characteristic structure, the composition of the glued layer (40) formed on the upper and lower ends of the cup body (30), and the interlacing of the concave sides (31) and the flange sides (32) design, supplemented by the setting of these beveled sides (33), not only can improve the structural strength of the cup body (30), but also achieve the best heat insulation effect, and reduce the cost of the heat insulation structure, thereby improving the paper cup The use quality and industrial competitiveness.

In summary, the present invention has excellent progressive practicability among similar products. At the same time, no similar structure has been found to exist in the technical data and literature of this type of structure at home and abroad. Therefore, The present invention already meets the requirements of an invention patent, and an application is filed according to the law.
