Description

Non-woven structure and brewing bag containing the same

The present invention relates to a non-woven structure; the present invention relates to a brewing bag comprising the aforementioned non-woven structure.

Coffee and tea can be said to be an indispensable drink in contemporary society. Whether it is at home, in the office, in public or on the roadside, coffee and tea are almost everywhere; it reflects coffee and tea drinks in it. An indispensable position in social life.

The rising population of drinking coffee and tea beverages and the improvement of living standards have become more and more demanding on the taste of coffee and tea beverages.

As far as coffee is concerned, from the instant instant coffee to the extent that more and more people do not grind coffee, the ground coffee is usually filled with finely granulated coffee beans in a brewing bag and soaked in hot water. After a period of time, the hot water flows into the container through the gap of the brewing bag. However, because the user's personal preference for different types of coffee is different, even if the same kind of coffee, the user's taste of the coffee is not the same, so The time of grinding the coffee in hot water needs to be adjusted according to the user's preference and taste, so that the coffee can reach the best flavor of personal preference. If the user prefers the lighter coffee taste, it can be directly immersed for a short time. It flows into the container, and if the user likes the richer coffee taste, it takes a long time to get the best drinking flavor. Therefore, in order to make different coffee preferences and flavors, the general user must prepare various brewing bags of different densities, and control the soaking time by the brewing bags of different densities, which is not troublesome for the user.

The teas familiar to Chinese people are also like coffee. The preferences of different types of tea are different. Even if they are the same type of tea, the taste of the tea is not the same. When brewing bags, the hot water is used. The time for soaking the tea leaves needs to be adjusted according to the user's preference and taste, so that the tea leaves can reach the best flavor of personal preference. However, like coffee, the general users must prepare different kinds for different tea preferences and tastes. Density brewing bags, which control the soaking time by different density brewing bags, also cause trouble to the user.

In view of this, the present invention has improved the prior art to improve the current user's need to prepare a plurality of brewing bags of different densities in response to different shades of coffee beans or tea leaves.

The present invention provides a non-woven fabric structure for a brewing bag, comprising: a hydrophilic non-woven fabric layer and a water-repellent non-woven fabric layer, wherein the hydrophilic non-woven fabric layer and the water-repellent non-woven fabric layer are bonded to each other by a plurality of adhesive points. The hydrophilic non-woven layer and the water-repellent non-woven fabric layer outside the bonding point do not stick, and the size and distance of the bonding point can determine the flow rate of the liquid through the non-woven fabric structure, and the specifications of the hydrophilic non-woven fabric layer and the water-repellent non-woven fabric layer are each 10 Up to 20 g/m 2 , the bonding point has a diameter ranging from 0.03 mm to 2 mm, and the distance between the bonding points is between 3 mm and 1 cm.

Preferably, the water-repellent non-woven fabric layer is formed by hot rolling or ultrasonic bonding of two layers of spunbonded nonwoven fabric; the water-repellent non-woven fabric layer may also be formed by hot-rolling or ultrasonic bonding by spunbonded nonwoven fabric or melt-blown nonwoven fabric.

The present invention further provides a brewing bag, comprising: a brewing bag body, wherein the brewing bag body is formed by the non-woven fabric structure, and the brewing bag body has an accommodating space and an opening, the accommodating space The opening is located in the body of the brewing bag, and the opening is opened in the body of the brewing bag and communicates with the accommodating space.

When the user needs to brew the coffee beans or the tea leaves for a long time according to personal preference, the water-repellent non-woven fabric layer is turned to the outside of the body of the brewing bag, and the ground coffee beans or tea leaves are placed in the accommodating space. Inside, the hot water is poured into the accommodating space to soak the ground coffee beans or tea leaves, the hydrophilic non-woven layer of the inner layer can quickly absorb the hot water, and the hydrophobicity of the outer layer water-repellent non-woven layer enables the hot water to be accommodated. The space stays in the space for a period of time, and passes through the hydrophilic non-woven layer and the water-repellent non-woven layer outside the bonding point, and then penetrates the water-repellent non-woven layer to flow out of the brewing bag body, thereby increasing the hot water soaking and grinding the coffee beans or tea leaves. When the coffee bean or the tea leaves with short soaking time are needed, the brewing bag is only required to be turned over the body so that the hydrophilic non-woven fabric layer is located outside the body of the brewing bag, because the hydrophilic non-woven layer The water absorption property enables the hot water to be accelerated through the water-repellent non-woven layer, thereby achieving the purpose of quick soaking. This creation is suitable for coffee beans or tea needs with long soaking time or short soaking time, so it can improve the burden on the user when preparing materials.

Preferably, the brewing bag further comprises a discarding portion, the discarding portion is connected to the brewing bag body along the opening, and the discarding portion closes the accommodating space.

Preferably, the infusion bag body further comprises two ear hanging members, the ear hanging members are adhesively fixed on the outer side of the infusion bag body and oppositely, and each ear hanging member comprises a fixing portion, a connecting portion and a hook. The fixing portion is adhesively fixed to the outer side of the brewing bag body, and the connecting portion connects the hook portion and the fixing portion. The ear pendant can be hung on the edge of the container, thereby avoiding the inconvenience of the user to hold the brewing bag during the brewing process.
