Description

Technical Field

[0001] This utility model relates to the field of biodegradable straws, and in particular to a biodegradable porous straw. Background Technology

[0002] A straw is a tubular tool used to drink liquids, commonly found in beverage settings. It is generally made of plastic, paper, or biodegradable materials. One end is inserted into the beverage, and the other end is for the person to suck. It uses atmospheric pressure to make the liquid rise. Modern straws come in various styles, including straight, curved, and others, to suit different beverages and drinking needs. They are very common and practical in daily life.

[0003] Existing straws are mostly made of plastic, which is difficult to degrade and causes serious environmental pollution when used in large quantities. While paper straws have some degradability, they have obvious shortcomings. They soften and deform easily when in contact with liquids, which not only affects the user experience, but also may break or break due to their poor strength and durability. Therefore, those skilled in the art have provided a biodegradable porous straw to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a biodegradable porous straw that exhibits strong stability during use. Furthermore, all layers of the straw are designed to be biodegradable, aligning with the current concept of sustainable development and possessing promising market prospects and social value.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A biodegradable porous straw includes a straw body and a base layer. A porous mechanism is fixedly provided at the upper end of the straw body. A reinforcing mechanism is fixedly provided on the outer surface of the straw body. An inner reinforcing layer is fixedly provided on the inner surface of the base layer. An inner waterproof layer is fixedly provided on the inner surface of the inner reinforcing layer. An outer reinforcing layer is fixedly provided on the outer surface of the base layer. An outer waterproof layer is fixedly provided on the outer surface of the outer reinforcing layer.

[0007] The reinforcement mechanism includes a first limiting ring, a stabilizing plate, and a second limiting ring. Adhesive layers are fixedly provided on both sides of the lower end of the stabilizing plate, and protective layers are fixedly provided at the lower ends of both adhesive layers.

[0008] Furthermore, the straw body includes a first tube and a second tube, with a limit tube fixedly provided at the upper end of the second tube and a piercing head fixedly provided at the lower end of the second tube.

[0009] Furthermore, the second tube is movably fitted inside the first tube.

[0010] Furthermore, the porous mechanism includes a connector, a first suction nozzle is fixedly disposed on one side of the connector, and a second suction nozzle is fixedly disposed on the other side of the connector.

[0011] Furthermore, the first limiting ring is fixedly disposed at a position slightly above the upper end of the outer surface of the first tube, and the second limiting ring is disposed at a position slightly below the upper end of the outer surface of the second tube.

[0012] Furthermore, the inner waterproof layer is made of polylactic acid film, and the inner reinforcing layer is made of bamboo fiber biodegradable composite material.

[0013] Furthermore, the base layer is made of a blend of polyadipate and polylactic acid.

[0014] Furthermore, the outer reinforcing layer is made of wood fiber biodegradable composite material, and the outer waterproof layer is made of biodegradable starch-based coating.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a biodegradable porous straw. The reinforcing mechanism is fixed to a specific position on the outer wall of the first tube by a first limiting ring and a second limiting ring. The distance between the two rings forms an installation groove to support the stabilizing plate. Adhesive layers are arranged on both sides of the bottom of the stabilizing plate to directly bond to the sealing surface of the beverage packaging. The straw fixing effect is enhanced by the dual action of mechanical limiting and chemical adhesion. The bottom of the adhesive layer is covered with a protective layer to effectively isolate moisture, grease or other external environmental interference and ensure the stability of the bonding interface. The combination of the limiting ring and the adhesive layer ensures the stability of the straw during use.

[0017] 2. The present invention proposes a biodegradable porous straw with an inner waterproof layer made of polylactic acid film, which can block liquid penetration and protect the internal structure. The inner reinforcing layer reinforced with bamboo fiber improves the compressive strength and prevents the straw from deforming under pressure. The base layer is made of a blend of polyadipate and polylactic acid to balance flexibility and rigidity and support the overall structure. The outer reinforcing layer uses wood fiber composite material to enhance external durability. The biodegradable starch-based coating of the outer waterproof layer provides external moisture protection and accelerates environmental degradation. All materials in each layer are based on biodegradable design, which is in line with the current concept of sustainable development and has good market prospects and social value.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-4 This utility model provides an embodiment of a biodegradable porous straw, comprising a straw body 1 and a base layer 6. A porous mechanism 2 is fixedly disposed at the upper end of the straw body 1, a reinforcing mechanism 3 is fixedly disposed on the outer surface of the straw body 1, an inner reinforcing layer 5 is fixedly disposed on the inner surface of the base layer 6, an inner waterproof layer 4 is fixedly disposed on the inner surface of the inner reinforcing layer 5, an outer reinforcing layer 7 is fixedly disposed on the outer surface of the base layer 6, and an outer waterproof layer 8 is fixedly disposed on the outer surface of the outer reinforcing layer 7. The inner waterproof layer 4 is made of polylactic acid film, the inner reinforcing layer 5 is made of bamboo fiber biodegradable composite material, the base layer 6 is made of a blend of polyadipate and polylactic acid, the outer reinforcing layer 7 is made of wood fiber biodegradable composite material, and the outer waterproof layer 8 is made of biodegradable starch-based coating.

[0026] Specifically, the straw body 1 connects to other components of the straw; the porous structure 2 increases the liquid-sucking channel; the reinforcing structure 3 enhances the stability of the straw; the inner waterproof layer 4 uses a polylactic acid film, which effectively prevents beverages from penetrating into other layers inside the straw, ensuring normal use; the inner reinforcing layer 5 uses a biodegradable bamboo fiber composite material, whose high strength enhances the straw's internal pressure resistance, preventing deformation due to compression during use; the base layer 6, as the basic structural layer of the straw, is made of a blend of polyadipate and polylactic acid, combining the flexibility of adipate and the rigidity of polylactic acid to provide good structural support for the straw; the outer reinforcing layer 7 uses a biodegradable wood fiber composite material, further enhancing the external strength of the straw and making it more durable; and the outer waterproof layer 8 uses a biodegradable starch-based coating, which prevents external moisture from eroding the straw and can rapidly degrade in the natural environment, meeting environmental protection requirements.

[0027] Reference Figure 1 , Figure 2 The straw body 1 includes a first tube 101 and a second tube 103. A limit tube 102 is fixedly provided at the upper end of the second tube 103, and a piercing head 104 is fixedly provided at the lower end of the second tube 103. The second tube 103 is movably sleeved inside the first tube 101. The multi-hole mechanism 2 includes a connector 202. A first suction nozzle 201 is fixedly provided on one side of the connector 202, and a second suction nozzle 203 is fixedly provided on the other side of the connector 202.

[0028] Specifically, in the straw body 1, the second tube 103 is movably fitted inside the first tube 101. When needed, the second tube 103 can be pulled out of the first tube 101 to accommodate beverage containers of different heights. The limiting tube 102 prevents the second tube 103 from being completely pulled out of the first tube 101, thus acting as a limit. The piercing head 104 facilitates the straw's penetration of the sealed beverage packaging. In the multi-hole mechanism 2, the connector 202 connects the first nozzle 201 and the second nozzle 203 together. When sipping a beverage, the user can simultaneously sip liquid through the first nozzle 201 and the second nozzle 203, greatly improving the sip speed. Especially for beverages containing fruit pulp or pearls, the multiple channels effectively reduce the probability of blockage.

[0029] Reference Figure 3 The reinforcement mechanism 3 includes a first limiting ring 301, a stabilizing plate 302, and a second limiting ring 305. Adhesive layers 303 are fixedly provided on both sides of the lower end of the stabilizing plate 302, and protective layers 304 are fixedly provided at the lower ends of the two adhesive layers 303. The first limiting ring 301 is fixedly provided at the upper part of the outer surface of the first tube 101, and the second limiting ring 305 is fixedly provided at the lower part of the outer surface of the first tube 101.

[0030] Specifically, the first limiting ring 301 and the second limiting ring 305 in the reinforcing mechanism 3 are fixed at specific positions on the outer surface of the first tube body 101. The space between them is used to install the stabilizing plate 302. The stabilizing plate 302 is connected to the beverage sealing packaging through the adhesive layers 303 on both sides of the lower end, which further enhances the structural stability of the straw. The protective layer 304 at the lower end of the adhesive layer 303 can protect the adhesive layer 303 from the influence of external factors.

[0031] Working principle: When using the biodegradable porous straw, first align the piercing head 104 of the straw with the seal of the beverage packaging and forcefully pierce it to insert the straw into the beverage. If the beverage container is high, the second tube 103 can be pulled out from the first tube 101 until the limiting tube 102 reaches the upper end of the first tube 101 to adapt to the height of the container. When drinking, two users can simultaneously suck up the liquid through the first nozzle 201 and the second nozzle 203 respectively. The first limiting ring 301, the stabilizing plate 302, and the second limiting ring 305 in the reinforcement mechanism 3 work together to ensure the stability of the straw during use and prevent the straw from shaking or deforming. The inner waterproof layer 4 and the outer waterproof layer 8 prevent the beverage from penetrating into the straw and prevent external moisture from eroding the straw, respectively. The inner reinforcing layer 5 and the outer reinforcing layer 7 enhance the straw's compressive strength and durability. After use, since the straw is made of biodegradable materials, it can be discarded in a suitable environment to gradually degrade under natural conditions, reducing environmental pollution.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
