Drip bag

Abstract

A drip bag is devised so that the good taste of coffee made by a conventional paper drip system can be obtained using a simple construction, and so that the drip bag can be set easily and securely on the cup even in cases where the thickness of the walls of the opening part of the cup is large. The drip bag includes a bag main body which is made of a water-permeable filtering sheet material and which has an opening part in the upper end portion of said bag main body, holding members which are made of a thin sheet-form material and which are disposed on the outside surfaces of two opposite sides of the bag main body, and reinforcing parts which are made of a thin sheet-form material and which are pasted to the outside surface of the bag main body around the peripheral parts of the holding members. Each of these holding members is formed from a tongue part which is pasted to the outside surface of the bag main body, an arm part which is located on the periphery of the tongue part, which is continuous with the lower end of the tongue part and which is formed so that said arm part can be pulled out from the bag main body, and a peripheral edge part of a specified shape, which is located on the periphery of the arm part and which is continuous with the central portion of the upper end of the arm part.

Description

technical field [0001] The present invention relates to a drip filter bag which is hooked to the upper part of a container such as a cup so that drip coffee can be easily put in. Background technique [0002] In the past, the paper drip filter method has been widely used as a coffee brewing method that can easily enjoy authentic coffee. In this type of paper drip filter, multiple persons (multiple cups) of coffee are usually extracted at one time. [0003] On the other hand, in recent years, the number of people living alone has increased, and the number of members of a family has decreased due to small families or a decline in the birth rate. Therefore, instead of the traditional paper drip filter method for extracting multiple cups of coffee, disposable single-bag coffee (hereinafter referred to as "one-off coffee") for the purpose of easily extracting one cup of coffee has been sold in the market in various product forms. for drip filter bags). [0004] Among them, as ...

Problems solved by technology

[0013] However, there is such a problem in the above-mentioned coffee drip filter bag 10, that is, when the wall thickness of the opening of the cup wall 30 is relatively thin, if Figure 5A As shown, although the wall 32 that clamps the opening of the cup 30 can be ensured by the peripheral portion 4 and the arm portion 5, as Figure 5B As shown, in the case where the wall 32 of the opening of the cup wall 30 is thicker, it is impossible to ensure that the wall 32 is clamped by the peripheral portion 4 and the arm portion 5, so as shown by the arrow, the hooking part 3 is easy to connect with the cup 30. break away
