Abstract

A paper straw is a paper straw body having a paper layer and a coating layer, and a coating layer is coated on the outer surface of the paper layer to form a composite paper layer, and both sides of the composite paper layer are melted and combined into a hollow annular shape, and the above The fusion bonding position forms an overlapping section, and the outer surface of the overlapping section is pressed with a plurality of biting flowers, thereby making the overlapping section of the paper straw body have the effect of increasing structural strength and enhancing bonding ability.

Description

Paper straw

The present invention is a paper straw, especially a paper straw with a bite on the surface, which can enhance the structural strength and bonding ability of the paper straw by biting flowers.

The straws used today are still made of plastic straws. Although plastic straws are convenient, they are not easy to recycle after use and cause great harm to the environment. Therefore, after active research and development, there have been metal straws, glass straws, sugar cane straws and paper. A straw such as a straw is proposed, and a paper straw is known to expose a surface of the long paper sheet with a liquid-repellent waterproofing membrane, and the paper sheet is curled so that the two sides overlap each other to form a cylindrical paper straw, and the waterproof film is located on the inner surface of the paper sheet. However, there is still room for reinforcement on the sides of the paper straw. In view of this, the new creators have been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the new creators will have a practical and practical creation.

The present invention discloses a paper straw comprising a paper straw body having a paper layer and a coating layer, the coating layer being coated on the outer surface of the paper layer to form a composite paper layer, the two sides of the composite paper layer being The fusion bonding has a hollow annular shape, and the fusion bonding position forms an overlapping section, and the outer surface of the overlapping section is pressed with a plurality of bites.

With the above structure, the two sides of the composite paper layer are melt-bonded and then passed through a pressure. The formation of the biting flowers is such that the overlapping section of the paper straw body can increase the structural strength and enhance the bonding ability.

Referring to FIG. 1 , a paper straw according to the present invention is a paper straw body 10 formed by melt-bonding the two sides of a composite paper layer 12, and the surface of the paper straw body 10 is pressed with a plurality of bites 16 , and One end of the paper straw body 10 is a diagonal insertion portion 18.

Referring to FIG. 2, it is disclosed that the pattern of the bite 16 is a twill embossing, but the pattern of the bite 16 is not limited, and may be a double cross or other embossed pattern. The purpose of the biting 16 is to increase the composite layer. The ability to combine the two sides of the 12 reduces the possibility of loosening.

Referring to FIG. 2A and FIG. 1 and FIG. 2, a paper suction tube body 10 is disclosed. The overlapping section 14 is formed by overlapping the two sides of the composite paper layer 12, and the overlapping section 14 is sequentially from the top to the bottom of the coating layer 132, the paper layer 131, the coating layer 132 and the paper layer 131. When the overlapping section 14 is subjected to pressure, the coating layer 132 and the sheet layer 131 on the surface of the paper straw body 10 are both recessed downward to form the biting flowers 16.

Referring to FIG. 3 and FIG. 4 together with FIG. 1 , it is disclosed that the composite paper layer 12 is chamfered at the top to form a triangular head 121 , and then the two sides of the composite paper layer 12 are melted and combined into a hollow annular shape. The above-described bonding position forms the overlapping section 14, and the triangular head 121 forms the oblique insertion portion 18.

Referring to FIG. 5 and FIG. 4 , in the first embodiment of the paper straw body 10 , the paper straw body 10 has a paper sheet layer 131 and a coating layer 132 . The laminating layer 132 is disposed on the outer surface of the paper sheet layer 131 to form the composite paper layer 12, and the paper straw body 10 can be formed by melt-bonding the two sides of the composite paper layer 12.

Referring to FIG. 6 and FIG. 4, in a second embodiment of the paper straw body 10, after the paper straw body 10 is sectioned, the paper straw body 10 has a paper layer 131, a coating layer 132 and a The second coating layer 133 is disposed on the outer surface of the paper sheet layer 131. The inner surface of the paper sheet layer 131 is covered with the second coating layer 133. The paper layer 131 and the coating layer 132 are covered. The second coating layer 133 forms the composite paper layer 12, and the paper straw body 10 can be formed by melt-bonding the two sides of the composite paper layer 12.

Referring to FIG. 7 and FIG. 4 and FIG. 5, the embossing manner of the biting flowers 16 is performed by first winding the composite paper layer 12 on a core mold 20, and then heating the core mold 20, The coating layer 132 of the composite paper layer 12 is melted and combined with the paper sheet layer 131 to form the overlapping portion 14, and then the overlapping portion 14 is rolled by using an embossing roller 22, so that the straw body 10 can be The overlapping section 14 has the bite 16; in addition, the embossing roller 22 can be embossed in a heated or unheated manner.
