Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of straws, in particular to a multifunctional degradable plastic straw. Background Art
[0002] Degradable materials are materials that can be degraded both thermodynamically and kinetically over a period of time. Among them, starch plastic, as a type of degradable material, is widely used in various tableware, especially disposable straws. Degradable straws made of starch plastic are completely biodegradable in various environments, and the starch molecules in the plastic form carbon dioxide gas after degradation or incineration, which does not toxic the soil or air. At the same time, starch is a renewable resource and is inexhaustible. The development of starch utilization is beneficial to the development of the rural economy. Therefore, degradable plastics have gradually replaced traditional plastic straws and are widely used in the field of disposable catering.
[0003] Most existing plastic straws can only be used for drinking water, and their functions are too single. When people drink beverages with particles, such as fruit juice with fruit particles, different groups of people have different needs. Some people like to eat fruit particles while drinking juice, while others only like to drink pure juice. At the same time, different groups of people have very different tastes. For example, when drinking coffee, some people like the original flavor while others like to add sugar. Therefore, in order to improve the functionality of existing straws, we provide a multifunctional degradable plastic straw. Utility Model Content
[0004] The utility model discloses a multifunctional degradable plastic straw, aiming to solve the technical problem that the existing straws have too single function.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0021] The utility model discloses a multifunctional degradable plastic straw which is mainly used in dining and drinking scenes.
[0022] Reference Figures 1 to 4 A multifunctional degradable plastic straw comprises a straw 1, a filter disc 2 is arranged at the lower part of the interior of the straw 1, one side of the filter disc 2 is fixed to the inner wall of the straw 1, a traction strip 3 is fixed to the outer side of the straw 1, the top end of the traction strip 3 is fixed to the upper part of the outer wall of the straw 1, and the bottom end of the traction strip 3 is fixed to the other side of the filter disc 2.
[0023] In this embodiment: the user holds the straw 1, and inserts the tip of the straw 1 vertically into the cup with the tip facing downward, and at the same time wraps the top of the straw 1 with the mouth, and inhales upward forcefully to drink the beverage; when the user does not want to drink the large-particle base material added to the beverage, the user directly sucks the straw with the mouth, and the large-particle base material in the cup cannot pass through the straw 1 due to the obstruction of the filter 2, so that the user can only drink the pure beverage; when the user wants to drink the large-particle base material added to the beverage, the user holds the top of the straw 1 and bends it to one side, and the top of the straw 1 is forced to be curved While deforming, the traction strip 3 will be pulled, and the traction strip 3 will pull one side of the filter 2, causing the filter 2 to deform around the connection between its side end and the straw 1 and flip over, exposing the bottom of the straw 1 completely. The base material in the beverage loses the cover of the filter 2, and is thus delivered into the user's mouth as the user sucks with his mouth. The beneficial effect is: by adding a flippable filter 2 at the bottom of the straw 1, the user can control the flipping of the filter 2 by bending the top of the straw 1 and pulling the filter 2 with the traction strip 3, thereby controlling the size of the material that can pass through the straw 1, thereby increasing the practicality of the straw 1.
[0024] Among them, it is necessary to supplement that: a fixing block 7 is horizontally fixed to the outside of the straw 1, and the traction bar 3 vertically passes through the fixing block 7. Figure 1 to Figure 2 Considering that the traction bar 3 itself has a large length, we set a fixing block 7 to limit the middle part of the traction bar 3 to prevent the traction bar 3 from getting in the way.
[0025] It is further explained that the top of the straw 1 is set as an arc-shaped tube structure inclined to one side, and the top of the filter 2 is fixed to the outside of the arc-shaped tube structure. Figure 1 to Figure 2 , we set the top of the straw 1 to be an arc-shaped tube structure, so that it is more convenient for the user to bend the straw 1.
[0026] In the above solution, considering that most existing straws 1 cannot adjust the taste of beverages according to the needs of users, especially bitter beverages such as coffee, in order to further improve the functionality of the straw 1, the specific operation is as follows.
[0027] Reference Figures 1 to 4 In a preferred embodiment, a stopper 4 is horizontally fixed on the upper outer side of the straw 1, the traction bar 3 vertically passes through the stopper 4, a cavity 5 is provided inside the stopper 4, the cavity 5 horizontally passes through the interior of the straw 1, powdered sugar is placed inside the cavity 5, and a sugar coating 6 is horizontally fixed at the intersection of the cavity 5 and the interior of the straw 1, and the sugar coating 6 is composed of a hard sugar.
[0028] In this embodiment, when the user inserts the straw 1 into the beverage, the stopper 4 located at the top of the straw 1 will generate a resistance force on the straw 1 to prevent the straw 1 from sliding into the beverage. At the same time, when the user drinks a bitter beverage such as coffee, the user can pinch the stopper 4 with his hand, and the sugar coating 6 located at the side end of the stopper 4 is squeezed and broken. At this time, the powdered sugar in the cavity 5 loses its restriction and slides down the straw 1 into the beverage, thereby increasing the sweetness of the beverage according to the user's needs.
[0029] In the first solution, considering that the straw 1 as a disposable item will be thrown away by the user, adhering to the concept of environmental protection, it is necessary to ensure that the straw 1 does not cause pollution to the environment. The specific operation is as follows.
[0030] Reference Figures 1 to 4 In a preferred embodiment, the entire straw 1 is made of a degradable plastic material such as polylactic acid.
[0031] In this embodiment, when the straw 1 is thrown away by the user, the entire straw 1 will slowly degrade in the soil over time, thereby not polluting the environment.
[0032] Working principle: when in use, the user holds the straw 1, and inserts the tip of the straw 1 downward vertically into the cup, and at the same time wraps the top of the straw 1 with the mouth, and inhales upward forcefully to drink the beverage; when the user does not want to drink the large particles of base material added to the beverage, the user directly sucks the straw with the mouth, and the large particles of base material in the cup cannot pass through the straw 1 due to the obstruction of the filter 2, so that the user can only drink the pure beverage; when the user wants to drink the large particles of base material added to the beverage, the user holds the top of the straw 1 and bends it to one side, and the straw When the top of filter 1 is deformed in an arc shape by force, the traction strip 3 will be pulled, and the traction strip 3 will pull one side of the filter 2, causing the filter 2 to deform around the connection between the side end and the straw 1 and turn over, exposing the bottom of the straw 1 completely. The base material in the beverage loses the protection of the filter 2, and is thus delivered into the user's mouth as the user sucks with his mouth. When the user drinks bitter beverages such as coffee, the user can pinch the stopper 4 with his hand, and the sugar coating 6 at the side end of the stopper 4 is squeezed and broken. At this time, the sugar powder in the cavity 5 loses its restriction and slides down the straw 1 into the inside of the beverage.
[0033] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
