Technical Field

The invention relates to a drinking straw, in particular to an environment-friendly wood straw capable of being rapidly and naturally decomposed.

Background

The straw is a hollow tubular object, and is mostly applied to objects for absorbing liquid, such as tableware for drinking beverages, so that the straw is elegant and convenient for drinking beverages. In addition, the probability of purchasing beverages is increased due to hot summer weather, and generally, the shop and the consumer almost choose to use the disposable plastic straw as a tool for drinking beverages for the convenience of use and the hygiene problem.

However, the plastic used to make plastic straw is made of high molecular weight synthetic resin, which has no way of natural decomposition, and the dirt remained after using plastic straw is difficult to clean, the treatment cost is high, and it is relatively difficult to recycle, although it can be thrown into incinerator and general combustible garbage for treatment, the residue remained after incineration, and the disposal of waste smoke discharged during incineration are also a big problem at present.

Therefore, in order to overcome the problem of environmental pollution caused by disposable straws, two types of reusable environment-friendly straws and environment-friendly disposable straws are gradually developed. Most of the reusable environment-friendly straws are made of bamboo, medical steel or glass and the like, but the medical steel or glass straws are high in manufacturing cost, narrow in hollow parts, difficult to deeply clean and prone to breeding bacteria for a long time, and influence on body health.

The environment-friendly disposable straw is made of materials such as paper or bagasse granulation, but the cost of the paper straw is 10 times higher than that of a plastic straw, and the paper straw is softened when meeting carbonated beverages and has low durability. Although the bagasse granulation straw is low in cost and can be decomposed, the bagasse granulation straw contains polylactic acid (PLA), and the polylactic acid must be decomposed through special treatment of the bagasse granulation straw, so that more resources are consumed in the treatment of the bagasse granulation straw, and the environmental protection value of the bagasse granulation straw is questioned.

In view of the above, the present invention provides a wooden straw capable of being disassembled naturally to overcome the above problems.

Detailed Description

The invention provides a disposable straw made of natural materials, which can resist low temperature of minus 30 ℃ to high temperature of 100 ℃, and the wooden straw can be automatically decomposed after 1 to 6 months after use without specific environment, and can also be used as organic fertilizer, thus having great environmental protection value.

Referring to fig. 1 and 2, the structure of the wood straw according to the first embodiment of the present invention is illustrated, as shown in the figures, the wood straw 1 according to the present invention includes a hollow tube 10 and a colloid membrane 12, the colloid membrane 12 completely covers the outer surface and the inner surface of the hollow tube 10, the colloid membrane 12 of the present embodiment is edible glue made of completely natural components, the colloid membrane 12 can effectively penetrate into capillary pores on the surface of the hollow tube 10 to completely cover the hollow tube 10, so as to enhance the elasticity and softness of the hollow tube 10 and generate the protection effects of water and moisture resistance.

The hollow tube 10 is formed by winding a wood chip 14, the wood chip 14 is further provided with a second adhesive 16, the second adhesive 16 can be an edible adhesive with viscosity and completely natural components, and after the wood chip 14 is wound into a tubular shape, the wound wood chip 14 is adhered by the second adhesive 16 to form the hollow tube 10. The wood chip 14 of the embodiment is a slice made of ordinary wood, and the density of the wood chip 14 is more than 0.42g/cm³The wood used in the method, such as basswood chips, birch wood chips, maple wood chips, cedar wood chips, ash wood chips, rubber wood chips, paulownia wood chips, zelkova wood chips, juniper wood chips, poplar wood chips, fir wood chips, camphor wood chips or pine wood chips, has high density and high hardness and toughness, and can effectively improve the durability of the wooden straw 1.

After the structure of the wooden drinking straw 1 is described, referring to fig. 1 to 3, the method for manufacturing the wooden drinking straw 1 of the present invention is described, first, in step S10, the wood head piece 14 is wound and then bonded with the second adhesive 16 to form the hollow tubular body 10. Then, step S12 is performed to place the hollow tube 10 into a container filled with liquid edible gum, and the hollow tube 10 is soaked in the liquid edible gum for two hours, so that the edible gum effectively penetrates into the pores on the surface of the hollow tube 10, and the hollow tube 10 is completely covered by the edible gum.

And finally, in step S14, taking the hollow tube 10 out of the container filled with the liquid edible glue, air-drying for 10 minutes, baking the hollow tube 10 and the edible glue thereon with 75 ℃ (DEG C) wind for 15 minutes, so that the liquid edible glue is solidified to form the glue films 12 on the inner and outer surfaces of the hollow tube 10, thereby completing the manufacture of the wooden straw 1.

In addition to the structure of the above embodiments, the present invention further provides another embodiment of the wooden straw structure, referring to fig. 4 to 7, the wooden straw 2 structure of the present embodiment includes a hollow tube 20 and a glue film 22 coating the outer surface and the inner surface of the hollow tube 20. The colloid membrane 22 is edible colloid made of completely natural components, and can effectively penetrate into capillary pores on the surface of the hollow tube body 20 to effectively coat the hollow tube body 20, so as to improve the elasticity and softness of the hollow tube body 20 and generate the protection effects of water resistance, moisture resistance and the like.

Please refer to fig. 5 and fig. 6 in combination, the structure of the wood head piece 24 of the present embodiment is different from that of the first embodiment, the wood head piece 24 of the present embodiment includes two raw wood pieces 240 and 242, a paper piece 244 is sandwiched between the two raw wood pieces 240 and 242, wherein a first adhesive 246 is further laid between the two raw wood pieces 240 and 242 and the paper piece 244, respectively, and is an edible adhesive having viscosity and completely made of natural components, the first adhesive 246 is used to completely adhere the two raw wood pieces 240 and 242 and the paper piece 244 together; wherein the raw wood chips 240, 242 are thin slices made of general wood, and the density of the raw wood chips 240, 242 is at least more than 0.42g/cm³The wood used in the above-mentioned method, such as basswood chips, birch chips, maple chips, cedar chips, ash wood chips, rubber wood chips, paulownia wood chips, zelkova wood chips, juniper wood chips, poplar wood chips, fir wood chips, camphor wood chips or pine wood chips, has a high density and a high toughness and hardness, and effectively improves the durability of the wooden straw 2. The paper sheet 244 may be glassine, molded paper, or laminated paper, and the like, and the waterproof function and hardness of the wooden straw 2 can be improved by the paper sheet 244 having a higher density.

Referring to fig. 7, the two logs 240 and 242 and the paper 244 are completely adhered together to form the wood sheet 24, and then the wood sheet 24 is wound and adhered by a second adhesive 26 having adhesiveness to form the hollow tube 20; wherein the second glue 26 is a liquid edible glue which is made of all natural components and has viscosity. Finally, a colloid film 22 is formed on the inner surface and the outer surface of the hollow tube 20, and the manufacturing process of forming the colloid film 22 on the inner surface and the outer surface of the hollow tube 20 in this embodiment is the same as that in the first embodiment, so the description is not repeated.

In conclusion, the plastic straw is made of natural materials, can be naturally decomposed after 1-6 months, has short decomposition time and environmental protection value, and can ensure that the wooden straw has the effects of elasticity, softness, moisture resistance and the like due to the arrangement of the plastic film. In addition, the invention has the advantages of low manufacturing cost, simple structure, convenient and quick processing and extremely high production efficiency.
