Degradable paper cup with heat insulation effect

Abstract

The utility model relates to the technical field of paper cups, in particular to a degradable paper cup with a heat insulation effect, which comprises a paper cup opening (10), a paper cup bottom (20) matched with the paper cup opening (10), a spiral paper tube (30) arranged between the paper cup bottom (20) and the paper cup opening (10), and an air inlet head (40) detachably connected with the spiral paper tube (30). The whole paper cup is made of paper so as to achieve the purpose of being degradable, meanwhile, in order to achieve the heat insulation effect and prevent scalding, the spiral paper tube is designed between the paper cup bottom and the paper cup opening, air is blown into the spiral paper tube through the air inlet head so that the spiral paper tube can bulge, and therefore the heat conduction distance of hot water in the paper cup can be increased, and certainly, the heat conduction distance of the hot water in the paper cup can be increased. Air in the spiral paper tube is poor in heat conduction performance, and the heat insulation effect of the whole paper cup can be effectively improved.

Description

Technical Field

[0001] This utility model relates to the field of paper cup technology, and in particular to a biodegradable paper cup with heat insulation effect. Background Technology

[0002] Paper cups are paper containers made by mechanically processing and bonding base paper (white paperboard) made from chemical wood pulp. As a container for holding things, paper cups are widely used in the market. They can hold both dry goods and liquids.

[0003] In existing technologies, long-term observation has revealed that when staff use paper cups to drink hot liquids, the cups are easily shaken due to their thin walls and the high temperature, causing the liquid inside to spill and resulting in burns.

[0004] To improve the above situation, existing technologies also add some auxiliary heat insulation measures to the outside of the cup, such as adding a thick cup sleeve. Most of these cup sleeves are disposable. Although this measure achieves a heat insulation effect on the surface, the cup sleeve is not as easy to degrade as a paper cup. If the cup sleeve is made of plastic, it will cause environmental pollution. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a biodegradable paper cup with heat insulation effect. This paper cup not only has a good heat insulation effect, but is also easy to degrade and will not cause environmental pollution.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A biodegradable paper cup with heat insulation effect is characterized by comprising: a paper cup mouth, a paper cup bottom matched with the paper cup mouth, a spiral paper tube disposed between the paper cup bottom and the paper cup mouth, and an air inlet head installed on the spiral paper tube.

[0008] Preferably, the air intake head includes an air intake housing and an adhesive ring installed inside the air intake housing.

[0009] Compared with the prior art, this application has the following beneficial effects:

[0010] This invention is made entirely of paper to achieve biodegradability. In addition, to provide heat insulation and prevent burns, a spiral paper tube is designed between the bottom and the mouth of the paper cup. Air is blown into the spiral paper tube through the air inlet, causing the spiral paper tube to bulge. This increases the heat conduction distance of the hot water inside the paper cup. Of course, the air inside the spiral paper tube has poor thermal conductivity, which can effectively improve the heat insulation effect of the entire paper cup. Attached Figure Description

[0019] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0020] Example 1:

[0021] like Figure 1 and Figure 2 As shown, a biodegradable paper cup with heat insulation effect includes: a paper cup mouth 10, a paper cup bottom 20 matched with the paper cup mouth 10, a spiral paper tube 30 disposed between the paper cup bottom 20 and the paper cup mouth 10, and an air inlet head 40 installed on the spiral paper tube 30.

[0022] The biodegradable paper cup with heat insulation effect consists of a paper cup mouth 10, a paper cup bottom 20, a spiral paper tube 30 and an air inlet head 40. The paper cup mouth 10 and the paper cup bottom 20 are connected by the spiral paper tube 30. The entire paper cup is made of paper material and is easy to degrade.

[0023] Furthermore, when there is no gas in the spiral paper tube 30, the entire paper cup is in a wrinkled and compressed state (e.g., Figure 1 This significantly reduces the storage space required for paper cups. In use, simply install the air inlet head 40 onto the spiral paper tube 30, and then blow air into the spiral paper tube 30 through the air inlet head 40, causing the spiral paper tube 30 to inflate (as shown in the image). Figure 2 In this state, the paper cup can be used to collect water. The hot water is blocked by the air inside the spiral paper tube 30, which effectively plays a role in heat insulation.

[0024] like Figure 3and Figure 4 As shown, the air intake head 40 includes an air intake housing 41 and an adhesive ring 42 installed inside the air intake housing 41.

[0025] To prevent air from flowing out of the spiral paper tube 30 under stress, an adhesive ring 42 is provided inside the air inlet housing 41 of the air inlet head 40. When the spiral paper tube 30 is fully inflated, the air inlet head 40 is pressed down to make the adhesive rings 42 inside the air inlet housing 41 stick together, completely blocking the air from flowing out of the spiral paper tube 30 and effectively ensuring the heat insulation effect of the cup.

[0026] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims be included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.
