Description

Paper straw

The invention relates to a straw for use in a beverage, in particular to a paper straw which is environmentally friendly, can be naturally decomposed, and can reduce the amount of plastic.

Diet is still a major event and a necessary behavior for survival. Different cultures and countries create different food cultures. Differences in food culture will not only show differences in ingredients and cooking methods, but also cause differences in diet and utensils, such as: Most of the country uses chopsticks as the main tableware, while Western countries are good at using cutlery as the main tableware.

Although the food utensils used by people in different countries may vary depending on the food culture, one of the food utensils - straws, is a common appliance used for drinking beverages regardless of country or food culture.

In modern society, due to the improvement of material living standards, whether it is packaged beverages or on-site brewing beverages, the number of straws consumed by the global population is very alarming. At present, the straws that are used in a large part are still mainly made of plastic straws. Although the volume of each plastic straw is not large, the daily cumulative use is not comparable to other plastic utensils, and also because of plastic straws. It is small in size and difficult to handle even after recycling. Therefore, a large amount of straw waste is generated every day in the world. This large amount of plastic waste will increase the processing cost in addition to environmental hazards. In addition, plastic packaging The straw also has the problem of plasticizer residue or hot plastic precipitation of hot foods and drinks, which is a hazard to human health.

In order to solve the problem of the traditional plastic straw, a reusable straw has appeared in the market. A typical one is a straw made of stainless steel. Although the stainless steel straw has the advantage of being reusable, it needs to be carried around. The number is still limited and the penetration rate is very low. In the short term, it is still impossible to completely replace the traditional plastic straws and solve the environmental and human health problems caused by plastic straws.

The technical problem to be solved by the novel is to provide a paper straw which is environmentally friendly, can be naturally decomposed, and can reduce the amount of plastic and maintain human health and safety.

In order to solve the above technical problem, the present invention proposes a paper straw, comprising: a paper tube wound into a spiral tube structure, the axial ends of the spiral tube structure are connected to each other, and the edge portions of the paper sheets of the spiral tube structure are overlapped, overlapping The parts stick together.

Preferably, the material of the paper sheet is stone paper.

Preferably, the thickness of the paper sheet is between 95 and 105 micrometers (μm).

Preferably, the width of the overlapped portion is 1/4 to 1/2 of the width of the sheet.

In an embodiment of the invention, one side surface of the paper sheet has a film, and the film is glued together by heat fusion.

Preferably, the film is a food grade polyethylene film (PE).

In an embodiment of the invention, the helical tube structure comprises a bendable portion.

Preferably, wherein the bendable portion is a bellows structure.

Preferably, the width of the overlapping portion of the spiral tube structure of the bendable portion is smaller than the width of the other overlapping portions of the spiral tube structure.

The beneficial effects of the novel and its advantages are that the present invention proposes an environmental protection and Naturally decomposable paper straws, which can replace traditional plastic straws, thus reducing the amount of plastic and the amount of plastic waste.

The specific embodiments and other advantages and effects of the present invention will be described below in conjunction with the drawings.

First, please refer to Figs. 1 and 2, which are a structural exploded view and a plan configuration view of the first embodiment of the present paper suction pipe.

An embodiment of the paper straw proposed by the present invention, wherein the paper suction tube 10 is basically a tubular member which is wound into a spiral tube structure by the paper sheet 20. The axial ends of the spiral tube structure are in communication with each other. In other words, the paper suction tube 10 is a kind. a tubular member that is axially pierced at both ends; preferably, the elongated paper sheet 20 is used as a raw material, and the paper sheet 20 is wound in a diagonally-angled direction in a long straight rod-shaped mold 30 by a winding manufacturing process, thereby forming A spiral tube structure in which edges of the paper sheets 20 of the spiral tube structure are partially overlapped, wherein the overlapping portions 21 are bonded to each other.

Preferably, the paper sheet 20 is made of stone paper. Under the exposure of sunlight or ultraviolet light, the stone paper is naturally pulverized and decomposed over a period of time. Since the main component of the stone paper is natural stone, it will not be natural after being pulverized and decomposed. The environment causes serious harm.

The twist W1 of the overlapping portion 21 can determine the strength of the paper straw 10, for example, the larger the width W1, the harder the paper straw 10 will be, and the paper straw 10 will be softer, and the smaller the width W1 of the overlapping portion 21, the softer the paper straw 10 will be. And easy to bend.

In a preferred embodiment of the present invention, the thickness of the paper sheet 20 is between 95 and 105 micrometers (μm), and the width W1 of the overlapping portion 21 is 1/4 to 1/2 of the width W of the paper sheet.

The side surface of the paper sheet 20 has a film 22. Preferably, the film 22 is a food grade polyethylene film (PE). When the paper sheet 20 is wound into a spiral tube structure, it can be heated by means of heating. The film 22 is hot melted to glue the overlapping portions 21 together.

In another embodiment of the present invention, which includes a bendable paper straw 10a, the user can bend the paper suction tube 10a to achieve a suitable angle of use. For an embodiment of the flexible paper straw 10a, please refer to Figures 3 and 4, wherein the spiral tube structure of the paper suction tube 10a comprises a bendable portion 11, preferably wherein the bendable portion 11 is a bellows structure. (See Fig. 3); another embodiment is shown in Fig. 4, wherein the width W2 of the overlapping portion of the spiral tube structure of the bendable portion 11 is smaller than the width W1 of the other overlapping portion of the spiral tube structure, and therefore, the bendable portion The spiral tube structure of 11 is softer than the spiral tube structure at the remaining positions, so that the paper suction tube can be bent by applying force to the bendable portion 11.

Although the present invention has been disclosed above in the above embodiments, it is not intended to limit the present invention, and the skilled person can make some modifications and retouchings without departing from the spirit and scope of the present invention. The scope of patent protection is subject to the terms of the claims attached to this specification.
