Abstract

A moisture-resistant paper straw, which is mainly made of paper and made into a tubular body, and a wet strength agent layer is arranged in the tubular body to increase the humidity of the tubular body so that it can be placed in a drink to reduce the absorption of the water content of the drink Speed and moisture resistance can be used to extend the use time.

Description

Moisture-resistant paper straws

The present invention relates to a moisture-resistant paper straw, in particular to a paper straw structure that can withstand moisture to increase the use time.

Due to the large number of breakfast shops, convenience stores, tea shops and coffee shops, according to statistics, an average of 8 million straws are used every day in Taiwan. The straws are currently the most frequently used and most consumed eating utensils, but due to The straws are disposable consumables, and the most commonly used straws are made of plastic materials, which has caused a great threat of environmental pollution. In order to achieve the goal of environmental protection, glass, stainless steel or The straw made of ceramics and other materials can reduce the use of plastic straws due to the feature of being reusable. However, although the straws made of the above materials can be reused, it is quite inconvenient to clean. Later, the paper straw made of paper material was developed. Through the paper material, it can be used once without cleaning and can be naturally decomposed after being discarded. Therefore, it is quite popular among consumers. However, the biggest disadvantage of paper straws is that Made of paper material, the paper straw will soften or even decompose due to the absorption of the beverage within a short period of time when placed in the beverage. Therefore, how to improve the above-mentioned shortcomings is one of the technical difficulties that the inventors intend to solve. Where.

The main purpose of the present invention is: it is mainly made of paper material to make a tubular body, and a wet strength agent layer is arranged in the tubular body, so as to increase the wet strength of the tubular body and reduce the absorption of the drink after being placed in the drink. The speed of moisture and the degree of moisture resistance can be used to extend the use time.

Please refer to Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5, which are the three-dimensional appearance view, side cross-sectional view, top cross-sectional view, schematic diagram of preferred embodiments and further embodiments of the present invention Schematic diagram, as can be clearly seen from the figure, if the paper straw 1 of the present invention is made of a paper material into a tubular body 2, and a wet strength agent layer 3 is arranged in the tubular body 2 when the user After the paper straw 1 is placed in the drink, the tubular body 2 can achieve the purpose of sucking the drink. As mentioned above, since the tubular body 2 is made of paper, the tubular body 2 will absorb the drink after being put in Therefore, a wet strength agent layer 3 is provided in the tubular body 2 to achieve a certain degree of moisture resistance, and it can greatly reduce the speed of the tubular body 2’s low absorption of the water content of the drink, so that the paper straw 1 can be It can maintain at least longer use time than ordinary paper straws, and will not quickly soften or even decompose after contact with drinks; the wet strength agent contained in the wet strength agent layer is FENNOSTRENGTH 617- produced by Finland Kemira Company 2 (Wet Strength 617-2); In addition, the wet strength agent layer 3 is provided in the tubular body 2 as shown in Figure 4, the wet strength agent layer 3 is provided on the inner surface of the tubular body 2 and On the outer surface, since the drink only touches the inner and outer surfaces of the tubular body 2 when the drink is taken, the wet strength agent layer 3 is arranged on the inner and outer surfaces of the tubular body 2 to achieve moisture resistance; At the same time, the wet strength agent layer 3 is also added with nanosilver, so that when the saliva containing microorganisms contacts the paper straw 1, the growth rate of microorganisms, bacteria, and viruses can be slowed down to maintain hygiene.

To sum up, compared with the conventional paper straws that will become soft or even decompose in a short time of use, the paper straws 1 of the present invention are made by arranging the wet strength agent layer 3 in the tubular body 2. A certain degree of moisture resistance can be achieved, and the rate at which the tubular body 2 can absorb beverage water can be greatly reduced, which can greatly increase the service life of the paper straw 1 and improve the current environmental protection issues. This is a very valuable invention.

The above-listed embodiments are used to illustrate one of the preferred and feasible embodiments of the present invention, and are not used to limit the scope of the present invention. Anyone who is familiar with the art can do a little bit without departing from the spirit and scope of the present invention. Modifications and modifications, therefore, the scope of protection of the present invention shall be subject to those defined by the attached patent scope.
