Technical description

In the present invention, when a bag for extracting a palatable beverage is immersed in hot water and stirred, the used bag has a characteristic of being integrally molded by punching a sheet having water resistance and heat-fusibility. This is a bag for extracting a beverage. Furthermore, as raw materials for the extraction bag and tag, both the lactic acid fermentation of corn starch, the polymerization of the fermentation product, and the spinning bag of the polymer obtained from spinning of the polymer, the extraction bag having filterability and An evening bag made of a non-woven sheet of polylactic acid fiber having water resistance and heat-sealing property was used. This is a taste-extracting bag for extracting beverages having the characteristics of being completely decomposed by microorganisms in the soil after use. Background art

The tag attached to the bag for extracting a tasteful beverage has conventionally been attached to the bag with a knob at the tip, a thread-like part that encloses the knob and the ingredient of the taste-sensitive beverage, and connects the bag to the bag. It consists of three parts, the base used to do. These parts are connected by bonding or heat fusion. For this reason, many types of raw materials are required for tag production, and operations such as bonding or heat fusion are also required when connecting and assembling the parts. For example, Patent Document 1 discloses many examples such as a tag configuration and an aspect attached to a palatable beverage extraction bag.

Patent Document 1 Japanese Patent Laid-Open No. 7-61465 However, in the conventional taste-extracting beverage extraction bag, all three parts of the tag, the knob at the tip of the tag, the thread part connecting the knob and the extraction bag, and the base part for attaching the end of the thread part to the bag are all integrated.

Disclosure of the invention

(Problems to be solved by the invention)

Conventionally, a tag is composed of three parts: a tip knob, a thread-like part connecting the knob and the extraction bag, and a tag base for attaching the end of the thread-like part to the bag. However, a water-resistant sheet is punched out, and the entire tag consisting of these three parts is molded as a whole, and more preferably, a material having heat-fusibility is used for the sheet and the bag. The tag is also attached by heat-sealing to simplify the production process and increase productivity, and to develop a production method for a taste-extracting bag. In addition, considering the harmony with the environment, we examined the materials for extracting palatable beverages and tags, and developed an extraction bag that can be completely decomposed and processed by microorganisms in the soil after use. It is something to try.

(Means for solving problems)

'One,

As a result of studying the production method to further increase the productivity of taste-extracting beverage extraction bags, the tag portion of the extraction bag is only an accessory small part when viewed from the whole extraction bag. It was found that there are many types of raw materials required for preparation, and that processing takes a considerable amount of time. As a result of examining the productivity improvement, the entire tag has water resistance. We examined a method of punching a sheet to form it in one piece and completing it in one step.
