Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a PLA environmentally friendly straw. Background Art

[0002] A straw, or drinking straw, is a cylindrical, hollow product. Its main function is to drink beverages from a cup. It is also used to suck the marrow of some cooked animal long bones. Generally, the diameter is about 0.5 cm. When used to drink beverages such as yogurt and pearl milk tea, a thicker straw is used, and some have a diameter of 1.2 cm. Some less common straws with extremely small diameters are used for drinking hot drinks. When the straw is in use, the pointed end is used to break the plastic seal on the package. When inserting the beverage, the tip is easily bent, making it impossible for the paper straw to open the beverage. Therefore, patent publication number CN215383026U discloses a paper straw, which includes a straw body, one end of the straw body is fixedly connected to a reinforcement ring, the side of the reinforcement ring away from the straw body is fixedly connected to a pointed head, and the inner wall of the straw body is fixedly connected to an inner wall strip.

[0003] The straw strengthens the hardness of the tip by providing a reinforcing ring and an inner wall strip to prevent the tip from bending when inserting a drink. However, the reinforcing ring, the inner wall strip and other components are provided only to prevent the tip from bending, resulting in a complex structure and more materials, which is not conducive to energy conservation and environmental protection. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a PLA environmentally friendly straw to solve the problem that the straw is easily bent when inserted.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A PLA environmentally friendly straw comprises a straw body made of PLA degradable material, a pointed end is arranged at the bottom of the straw body, a flattened reinforcement portion is arranged at the tip side of the pointed end, a protruding block is arranged on the outer side of the flattened reinforcement portion, and a bevel portion is arranged at the bottom of the protruding block.

[0007] Preferably, a bendable structure is provided on the upper portion of the straw body.

[0008] Preferably, an annular thickened portion is fixedly connected to the top of the straw body, and a cambered ring is provided on the top of the annular thickened portion.

[0009] In summary, the beneficial effects of the utility model are:

[0010] First, the PLA environmentally friendly straw provided by the utility model is made by hot-melting and flattening the tip of the pointed end of the straw to harden the tip of the pointed end and make the flattened reinforced part hard as a whole. Therefore, the pointed end is not easy to bend when inserted into the plastic package, thereby achieving the effect of not being easy to bend and simplifying the processing technology, without excessive materials, which is beneficial to energy saving and environmental protection.

[0011] Second, when the flattened reinforcement portion cooperates with the pointed end to insert into the plastic seal, the inclined end is convenient for guiding the protruding block to be inserted into the plastic seal, thereby breaking the plastic seal. Since the protruding block protrudes from the straw body, after the straw body is inserted into the plastic seal, the plastic seal will not wrap the straw body, and the inside and outside of the box can be ventilated, so it will not be difficult to suck.

[0018] like Figure 1 - Figure 3As shown, the utility model provides a PLA environmentally friendly straw, comprising a straw body 1, and the straw body 1 is made of PLA degradable material, a pointed end 2 is arranged at the bottom of the straw body 1, a flattening reinforcement part 3 is arranged at the tip side of the pointed end 2, a protruding block 4 is arranged on the outer side of the flattening reinforcement part 3, and a bevel part 5 is arranged at the bottom of the protruding block 4. The straw is made of PLA environmentally friendly material, which is a new type of biodegradable material, and is made of renewable plant resources such as starch raw materials from corn, so it is more environmentally friendly and not easy to be swelled by water, which is the trend of the future. When making the straw, after the straw is normally made, one side of the pointed end 2 of the straw is hot-melt flattened to harden the tip of the pointed end 2 and make the flattened reinforcement part 3 hard as a whole. When in use, the pointed end 2 is not easy to bend when inserted into the plastic seal. In addition, when piercing the packaging box, the hole diameter is consistent with the diameter of the straw, thereby causing a difference in air pressure between the inside and outside of the box, making it difficult to suck. A protruding block 4 protruding from the straw body 1 is provided on the outside of the flattened reinforcement part 3. When the flattened reinforcement part 3 cooperates with the pointed end 2 to be inserted into the plastic seal, the inclined end facilitates guiding the protruding block 4 to be inserted into the plastic seal, thereby breaking the plastic seal. Since the protruding block 4 protrudes from the straw body 1, the plastic seal will not wrap the straw body 1 after the straw body 1 is inserted into the plastic seal, and the inside and outside of the box can be ventilated, so it is not difficult to suck.

[0019] The upper part of the straw body 1 is provided with a bendable structure 6. The bendable structure 6 enables the end of the straw body 1 to be bent, so as to facilitate sucking at different angles.

[0020] The top of the straw body 1 is fixedly connected with an annular thickened portion 7, and an arc surface ring 8 is arranged on the top of the annular thickened portion 7. When the mouth is close to the top of the straw body 1, the top of the straw body 1 is easy to poke the mouth. By providing the thickened portion to reinforce the top of the straw body 1, the top of the straw body 1 is bent and turned outward, so that the top of the straw body 1 forms an arc surface ring 8. Therefore, when the mouth is close, the arc surface structure contacts the mouth, the contact area is large, and it is not easy to poke the mouth.

[0021] Working principle: when in use, insert the pointed end 2 of the straw body 1 into the seal of the packaging box with force. The flattened reinforcement part 3 is hard as a whole, and the pointed end 2 is not easy to bend when inserted into the plastic seal. A protruding block 4 protruding from the straw body 1 is provided on the outside of the flattened reinforcement part 3. When the flattened reinforcement part 3 cooperates with the pointed end 2 to insert into the plastic seal, the inclined end is convenient for guiding the protruding block 4 to be inserted into the plastic seal, thereby breaking the plastic seal. Since the protruding block 4 protrudes from the straw body 1, after the straw body 1 is inserted into the plastic seal, the plastic seal will not wrap the straw body 1, and the inside and outside of the box can be ventilated, so it will not be difficult to suck. When the mouth is close to the sucking end of the straw body 1 for sucking, the arc surface structure of the arc surface ring 8 contacts the mouth, and the contact area is large, which is not easy to pierce the mouth.

[0022] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
