Description
Technical Field
[0001] The utility model relates to the technical field of disposable tableware, in particular to a degradable straw. Background Art
[0002] PLA straws have a similar taste to traditional plastics. At the same time, since the raw materials used are all degradable materials, the final straws are also degradable. PLA straws, as the name suggests, are straws produced from PLA as raw materials. PLA is polylactic acid, also known as polylactide, which is a polyester polymer obtained by polymerization of lactic acid as the main raw material. It is a new type of biodegradable material. It is made of starch raw materials from renewable plant resources (such as corn).
[0003] Common straws, after being inserted into a beverage box, completely destroy the sealing state of the beverage box. If the beverage is not finished and needs to be temporarily placed, it is difficult for ordinary straws to restore the sealing state of the beverage box. The beverage in the box is easy to overflow from the straw. At the same time, dust and bacteria are also easy to enter the beverage box through the straw. Therefore, a degradable straw is needed to meet people's needs. Utility Model Content

[0024] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a degradable straw, comprising a straw body 1; in order to solve the problem that it is difficult for ordinary straws to restore the sealed state of a beverage box, the beverage in the box is easy to overflow from the straw, and at the same time, dust and bacteria are also easy to enter the beverage box from the straw, an outer tube 2 is provided on the straw body 1, a folding tube 22 is installed on the top of the outer tube 2, a straw mouth 21 is installed on the other end of the folding tube 22, an extension tube 3 is slidably installed in the outer tube 2, a card interface 23 is provided at the bottom of the outer tube 2, the top of the extension tube 3 is adapted to the card interface 23, and a closing mechanism 4 is provided in the outer tube 2. When not in use temporarily, the beverage box is restored to a sealed state through the closing mechanism 4 to isolate the external environment, prevent the beverage from overflowing, and isolate external dust and bacteria at the same time;
[0025] In order to close the straw, the closing mechanism 4 includes a closing ring 41 and a plug-in column 42. The closing ring 41 is installed on the inner wall of the straw mouth 21, and the plug-in column 42 is installed on the inner wall of the outer tube 2. A plug-in hole 45 is opened in the closing ring 41, and the plug-in hole 45 is adapted to the plug-in column 42. Connecting blocks 46 are evenly distributed on the bottom of the plug-in column 42, and the other ends of the connecting blocks 46 are all installed on the inner wall of the outer tube 2. An upper convex ring 43 is provided on the outer side of the straw mouth 21, and the outer tube 2 The outer side of the outer tube 22 is provided with a lower convex ring 44, the closed ring 41 is located above the folding tube 22, the plug-in column 42 is located below the folding tube 22, the closed ring 41 is adapted to the upper convex ring 43, the plug-in column 42 is adapted to the lower convex ring 44, a connecting belt 47 is installed on one side of the upper convex ring 43, and a pipe mouth cover 48 is installed on the other end of the connecting belt 47. The pipe mouth cover 48 is adapted to the straw mouth 21. When using the straw, the extension tube 3 is pulled outward from the bottom of the outer tube 2 so that the top of the extension tube 3 is aligned with the outer tube 2. The card interface 23 at the bottom of the tube 2 is fixed by card connection, and then the upper convex ring 43 on the outside of the straw mouth 21 and the lower convex ring 44 on the outside of the outer tube 2 are pinched respectively, and pulled toward both ends to extend the folding tube 22 between the straw mouth 21 and the outer tube 2. In the process of pulling the folding tube 22, the plug-in column 42 is disengaged from the plug-in hole 45 of the closed ring 41, so that the straw mouth 21, the folding tube 22 and the outer tube 2 are connected, and the straw is inserted into the beverage box for use. When the beverage is not finished, it needs to be When temporarily storing, pinch the upper convex ring 43 on the outside of the straw mouth 21 and the lower convex ring 44 on the outside of the outer tube 2 with your hands, squeeze the folding tube 22 inward to fold the folding tube 22. During the folding process of the folding tube 22, reinsert the plug-in column 42 into the plug-in hole 45 of the closing ring 41 to close the folding tube 22, and then buckle the tube mouth cover 48 into the straw mouth 21 to prevent accidents that cause the beverage to flow out of the straw, and at the same time prevent dust from entering the straw from the straw mouth 21.
[0026] The working principle is as follows: when using the straw, the extension tube 3 is pulled outward from the bottom of the outer tube 2, so that the top of the extension tube 3 is connected and fixed with the card interface 23 at the bottom of the outer tube 2, and then the upper convex ring 43 on the outside of the straw mouth 21 and the lower convex ring 44 on the outside of the outer tube 2 are pinched respectively, and pulled toward both ends to pull and extend the folding tube 22 between the straw mouth 21 and the outer tube 2. In the process of pulling the folding tube 22, the plug-in column 42 is disengaged from the plug-in hole 45 of the closed ring 41, so that the straw mouth 21, the folding tube 22 and the outer tube 2 are connected, and the straw is inserted into the beverage box for use. When the beverage is not finished and needs to be temporarily stored, the straw is put into the beverage box. Pinch the upper convex ring 43 on the outside of the straw mouth 21 and the lower convex ring 44 on the outside of the outer tube 2 with your hands, and squeeze the folding tube 22 inward to fold the folding tube 22. During the folding process of the folding tube 22, reinsert the plug-in column 42 into the plug-in hole 45 of the closed ring 41 to close the folding tube 22, and then buckle the tube mouth cover 48 into the straw mouth 21 to prevent accidents that cause the beverage to flow out of the straw, and at the same time prevent dust from entering the straw from the straw mouth 21. The seal of the beverage box is pushed open by the prism 5 on the outside of the outer tube 2 to prevent the seal from being too close to the outside of the straw, making it difficult to absorb the beverage.
[0027] Example 2: Figure 1 and Figure 2 In order to prevent the outer wall of the straw from fitting too tightly to the seal of the beverage box, prisms 5 are evenly distributed on the outer tube 2, and the top of the prism 5 is installed at the bottom of the lower convex ring 44. The seal of the beverage box is pushed open by the prism 5 on the outside of the outer tube 2 to prevent the seal from fitting too tightly to the outside of the straw, making it difficult to absorb the beverage. The remaining features are the same as those of Example 1.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
