Description

Technical Field

[0001] The utility model relates to the field of tableware, in particular to a pair of combined chopsticks. Background Art

[0002] Chopsticks, a widely used tableware, have evolved over millennia, resulting in a diverse range of shapes and materials. However, traditional chopsticks, while typically one-piece, offer stability and reliability, but they are increasingly becoming inconvenient to carry, require significant storage space, and are less environmentally friendly in modern life.

[0003] Although some foldable or split combination chopsticks have appeared on the market, these combination chopsticks have the following problems:

[0004] (1) The connection is not firm and the user experience is not good: the chopstick head is restrained by the narrowed mouth at the connection between the chopstick body and the chopstick head is easy to shake inside the chopstick body when in use, thus affecting the dining experience.

[0005] (2) Large amounts of plastic are used, the production cost is high, and it is not environmentally friendly: In order to improve the strength of chopsticks, manufacturers usually increase the wall thickness of the chopstick cylinder and the joints, which leads to increased plastic consumption, high production costs, and adverse effects on the environment.

[0006] (3) Complex structure: The connection parts of some combination chopsticks involve structures such as threads, and the mold making cost is high, which greatly increases the production cost.

[0007] Therefore, there is an urgent need to design a combination of chopsticks that has a reliable connection, good user experience, reduces plastic and is environmentally friendly, and has a simple structure and low cost. Utility Model Content

[0008] The main purpose of the utility model is to provide a combination of chopsticks to solve the problems mentioned in the background technology.

[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0010] A pair of chopsticks comprises a grip and a clamping portion. The grip is a hollow cylindrical structure, with a combination hole defined at one end and a combination head defined at one end. Multiple ribs are symmetrically arranged along the inner wall of the combination hole, with the inner surfaces of the ribs fitting against the combination head, which is inserted into the combination hole.

[0011] Furthermore, the combination head is a cone-shaped structure with one end being large and the other end being small.

[0012] Furthermore, the ribs are provided with an inclination angle matching that of the combined head.

[0013] Furthermore, multiple anti-roll reinforcement ribs are provided at the other end of the grip, forming a regular hexagonal shape. This hexagonal structure gives the hollow cylindrical grip greater strength with the same wall thickness, eliminating the need to increase wall thickness to increase strength, thereby achieving the goals of reducing plastic, environmental protection, and cost.

[0014] Furthermore, the material of the hand grip is plastic, and the material of the clamping part is bamboo.

[0015] Furthermore, the plastic used for the grip is HC830 homopolymer high-crystalline polypropylene. Developed by Dongming Hengchang Chemical, HC830 offers outstanding rigidity, heat resistance, and gloss. These exceptional properties allow for thinner grip walls, significantly reducing plastic usage during the injection molding process.

[0016] Furthermore, the number of ribs is six. Too many ribs would increase the amount of plastic used; too few ribs would affect the stability of the connection between the grip and the clamp. After repeated experiments by technicians, the final number of ribs was determined to be six.

[0017] Furthermore, the rib length is 1.5 ± 0.5 cm. Ribs that are too long reduce rib utilization, increase plastic usage, and increase costs. Ribs that are too short also affect the stability of the connection between the grip and the clamp. After repeated testing by technicians, the rib length was ultimately determined to be 1.5 ± 0.5 cm.

[0018] The working principles of this utility model are as follows: (1) Reducing plastic and reducing costs: The regular hexagonal anti-roll reinforcement ribs on the grip give the hollow cylindrical grip greater strength at the same wall thickness, eliminating the need to increase the wall thickness to increase strength. Simultaneously, the number and length of the ribs are controlled, thereby achieving the goals of reducing plastic, protecting the environment, and reducing costs. Furthermore, the outstanding product properties of homopolymer high-crystalline polypropylene HC830 ensure that the grip wall thickness can be made thinner, significantly reducing the amount of plastic used during the injection molding process.

[0019] (2) Improved strength and connection stability: The hexagonal anti-roll reinforcement structure of the handle and the use of homopolymer high-crystalline polypropylene HC830 material improve the strength of the handle. When the combination head of the clamping part is inserted into the handle through the combination hole, due to the certain taper of the combination head and the certain inclination of the ribs, the contact surface of the combination head and the inner side of the ribs squeeze each other during the insertion process, and the insertion becomes tighter and tighter, making the combination chopstick connection more stable and reliable.

[0020] (3) User experience: The connection between the grip and the clamping part is firm and not prone to shaking. At the same time, the hexagonal anti-roll reinforcement structure of the grip makes the combination chopsticks not easy to roll off, which improves the user experience.

[0021] Compared with existing technologies, this utility model has the following beneficial effects: 1. Reduced plastic content, environmental protection, and cost reduction: By optimizing the structure and material of the handle, the use of plastic is significantly reduced, which is more environmentally friendly and reduces production costs. 2. Higher strength and more stable connection: The optimized structure and material selection of the handle result in higher strength and more stable connection. 3. Better user experience: The combination chopsticks are less likely to shake or roll during use, improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Example:

[0029] like Figures 1 to 4 As shown, a pair of combination chopsticks comprises a grip portion 1 and a clamping portion 2. The grip portion 1 is a hollow cylindrical structure, with a combination hole 11 defined at one end, and a combination head 21 defined at one end of the clamping portion 2. Multiple ribs 12 are symmetrically arranged along the inner wall of the combination hole 11. The inner surfaces 13 of the ribs 12 mate with the combination head 21, which is inserted into the combination hole 11.

[0030] Specifically, the assembly head 21 is a tapered structure with one end larger than the other, and the taper ranges from 3 to 35 degrees. The ribs 12 are arranged at an angle that matches the assembly head 21. There are six ribs 12, each measuring 1.5 ± 0.5 cm in length. The grip 1 is made of plastic, specifically HC830 homopolymer high-crystalline polypropylene developed by Dongming Hengchang Chemical. The clamping portion 2 is made of bamboo.

[0031] In addition, a plurality of anti-roll reinforcement ribs 3 are provided at the other end of the handle portion 1 , and the anti-roll reinforcement ribs 3 form a regular hexagon.

[0032] The working principles of the combination chopsticks of this utility model are as follows: (1) Reducing plastic and reducing costs: The regular hexagonal anti-roll reinforcement ribs 3 of the grip portion 1 give the hollow cylindrical grip portion 1 greater strength with the same wall thickness, eliminating the need to increase the wall thickness. Simultaneously, the number and length of the ribs 12 are controlled, thereby achieving the goals of reducing plastic, protecting the environment, and lowering costs. Furthermore, the outstanding product properties of homopolymer high-crystalline polypropylene HC830 ensure that the wall thickness of the grip portion 1 can be made thinner, significantly reducing the amount of plastic used during the injection molding process of the grip portion 1.

[0033] (2) Improving strength and connection stability: The structure of the regular hexagonal anti-roll reinforcement ribs 3 on the grip portion 1 and the use of homopolymer high-crystalline polypropylene HC830 material improve the strength of the grip portion 1. When the combination head 21 of the clamping portion 2 is inserted into the grip portion 1 through the combination hole 11, the combination head 21 has a certain taper and the ribs 12 have a certain inclination. During the insertion process, the combination head 21 and the inner contact surface 13 of the ribs 12 are pressed against each other, and the insertion becomes tighter and tighter, making the combination chopstick connection more stable and reliable.

[0034] (3) User experience: The connection between the grip portion 1 and the clamping portion 2 is firm and not prone to shaking. At the same time, the structure of the regular hexagonal anti-roll reinforcement rib 3 of the grip portion 1 makes the combination chopsticks not easy to roll off, thereby improving the user experience.

[0035] The above embodiments are only descriptions of the preferred implementation methods of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection of the present invention.
