Abstract
Description
Technical Field
[0001] This application relates to the construction of a beverage cup, and more particularly to an environmentally friendly beverage cup that is fully recyclable and biodegradable. Background Technology
[0002] To address the environmental problems caused by plastic bottles made of polyethylene terephthalate (PET) (PET is non-biodegradable), containers made from biodegradable and environmentally friendly materials have been proposed and put into mass production. For example, manufacturers in the United States, the United Kingdom, the Netherlands, and Denmark have proposed paper PET bottles made entirely using one-piece molding technology. While these PET bottles, made entirely of paper and using one-piece molding technology, have the advantages of being easy and quick to manufacture, their structural strength and pressure resistance are insufficient, making them unsuitable as soft drink bottles or for holding other pressurized beverages or liquids (such as sparkling water). Glass bottles and metal cans are another common type of container used for storing food or ingredients. While glass bottles can be recycled, they are easily broken and do not effectively block light or ultraviolet rays. Metal cans are generally made of tinplate, with a tin layer inside serving as the main protective layer. This layer isolates the food from the tin layer, preventing corrosion and blocking environmental factors, thus preventing the food from spoiling. However, metal cans are easily deformed or dented by external forces, which can affect their ability to preserve the freshness of stored food or ingredients.
[0003] Currently, containers made of biodegradable or recyclable materials (such as paper bottles) need to meet the following requirements in practice to overcome increasingly stringent environmental regulations and industry requirements, in order of priority: (1) each component is recyclable; (2) it is made using bio-based raw materials; and (3) it is biodegradable or biodegradable.
[0004] Currently, many eco-friendly containers that claim to be biodegradable or recyclable, although made of biodegradable or recyclable materials, often have components that are difficult to separate, making it impossible to classify and recycle each component separately and thus difficult to achieve the goal of complete recycling.

[0038] In the embodiments described below, the positional relationships include: up, down, left, and right. Unless otherwise specified, they are all based on the direction shown by the components in the diagram.
[0039] Please see Figure 1 and Figure 2 This is an exploded view of a preferred embodiment of the environmentally friendly beverage cup of this application.
[0040] A preferred embodiment of the environmentally friendly beverage cup of this application includes: a cup body A and a cup lid B. As a preferred embodiment, the cup body A and the cup lid B are made of polyethylene furanate (PEF), a 100% plant-based, high-barrier biopolymer polyester material. Due to the characteristics of its furan intermediate monomer molecular structure, PEF polyester material has superior gas barrier properties, heat resistance, and mechanical properties compared to existing PET bottle packaging materials. It is also hydrolyzable, easy to process, and can be used to manufacture lighter, thinner, and stronger beverage bottles, extending food shelf life and reducing carbon emissions by 50% to 70%.
[0041] As a preferred embodiment of this application, the cup body A is made of polyethylene furanate (PEF) and is translucent, that is, the cup body A is a transparent component, which allows the user to clearly see the contents when holding beverages. Especially when holding some contents with rich colors or layers, it can enhance its visual appeal, stimulate appetite and increase its attractiveness to consumers.
[0042] Cup body A is a container with its opening facing upwards. A preferred embodiment of cup body A includes: a cup wall 10, a cup mouth 20, and a base plate 30 (see...). Figure 4 The cup wall 10 is a tubular component, the bottom plate 30 is located at the bottom end of the cup wall 10, and the cup mouth 20 is connected to the top end of the cup wall 10 to form a cup mouth 21 that communicates with the interior of the cup wall 10. Preferably, the cup wall 10, the cup mouth 20, and the bottom plate 30 are integrally formed components. The cup mouth 20 includes an annular portion 22 and a rib 23. The annular portion 22 is a circular component, and the bottom end of the annular portion 22 is seamlessly connected to the top end of the cup wall 10. The top end of the annular portion 22 forms the cup mouth 21. A first threaded structure 24 is provided on the outer wall surface of the annular portion 22. The rib 23 is an annular flat plate structure provided on the outer wall surface of the annular portion 22 and extending outward in the radial direction.
[0043] In a preferred embodiment of this application, the cup wall 10 has a plurality of reinforcing ribs 11, a preferred embodiment of which extends from one end of the cup wall 10 along its axial direction toward the other end; see also Figure 7 In a preferred embodiment, viewed from the cross-section of the cup wall 10, the outline of the cup wall 10 is composed of a plurality of continuous and interconnected arc segments 12. Each arc segment 12 extends from one end of the axial direction of the cup wall 10 toward the other end to form the reinforcing rib 11. The structural strength of the cup wall 10 can be increased by the reinforcing rib 11.
[0044] In a preferred embodiment of this application, the cup wall 10 is a tubular component that is wider at the top and narrower at the bottom, preferably a tapered tubular component, for example, the outer surface of the cup wall has an angle G with the vertical line L (see...). Figure 4 Furthermore, the angle of the oblique angle G is between 1 and 2 degrees (1 to 2°). Therefore, the environmentally friendly beverage cups of this application can be easily stacked together for storage, and multiple environmentally friendly beverage cups can be stored in a limited space as much as possible.
[0045] The lid B can be engaged with the mouth portion 20 of the cup body A to close the mouth 21 of the cup body A. A preferred embodiment of the lid B includes: a cover plate 40, a sealing piece 50, an annular skirt 60, and a second threaded structure 61. The cover plate 40 is a component with a flat surface for covering the mouth 21 of the cup body A. The skirt 60 surrounds the periphery of the cover plate 40 and extends downward. The skirt 60 is coaxially fitted around the outside of the annular portion 22 of the mouth portion 20. The second threaded structure 61 is provided on the inner surface of the skirt 60 and can be screwed into the first threaded structure 24. Therefore, through the interaction of the first threaded structure 24 and the second threaded structure 61, the lid B can be engaged with the mouth 21 of the cup body A to close the mouth 21 of the cup body A.
[0046] Please see Figure 4 The sealing sheet 50 is integrally connected to the cover plate 40. In a preferred embodiment, the sealing sheet 50 is located at the center of the cover plate 40, and the periphery of the sealing sheet 50 is integrally connected to the cover plate 40 via a connecting sheet 51 (see...). Figure 5 A preferred embodiment is to use plastic injection molding technology to integrally mold the cup lid B using polyethylene furanate (PEF), wherein the thickness T1 of the connecting sheet 51 is less than the thickness T2 of the lid plate 40 (see...). Figure 5 A protruding component 52 is integrally connected to the top surface of the sealing sheet 50; the user can pinch the protruding component 52 and pull it upwards, simultaneously pulling the sealing sheet 50 upwards. The structure connecting the thin sheet 51 relative to the cover plate 40 will tear under external force. Therefore, the sealing sheet 50 and the protruding component 52 will be torn apart from the cover plate, creating a perforation 41 in the cover plate 40 (see...). Figure 5 This allows the straw (not shown in the figure) to be inserted into the cup body A through the perforation 41, so that the beverage inside can be consumed.
[0047] Please see Figure 6 In a preferred embodiment of this application, a sealing groove 42 is provided at the connection between the skirt 60 and the cover plate 40. Preferably, the sealing groove 42 has an arc-shaped inner side. When the cup lid B and the cup mouth 20 of the cup body A are joined, the top end of the annular part 22 of the cup mouth 20 can be tightly embedded in the inner side of the sealing groove 42. In other words, the cup mouth 21 of the cup body A can be tightly embedded in the inner side of the sealing groove 42 to prevent the beverage from leaking out at the cup mouth 21.
[0048] In a preferred embodiment of this application, the first thread structure 24 and the second thread structure 61 are double-threaded, allowing for quicker interlocking. Please refer to... Figure 2 , Figure 3In another preferred embodiment, both the first thread structure 24 and the second thread structure 61 are composed of several equally spaced thread lines. For example, the first thread structure 24 and the second thread structure 61 are composed of three equally spaced thread lines. In other words, the three equally spaced thread lines are located at the positions that divide the circumference equally, and there is a gap 70 between any two thread lines. Therefore, when the cup lid B and the cup body A are joined to close the cup mouth 21 of the cup body A, the second thread structure 61 of the cup lid B can directly pass through the gap 70. Then, the first thread structure 24 and the second thread structure 61 can be quickly screwed together by rotating the cup lid B less than one turn. This facilitates the quick completion of the beverage filling and sealing operations and saves working time.
