Description

  TECHNICAL FIELD The present invention relates to a sachet attaching device to a packaging bag for attaching a sachet containing an oxygen scavenger or a desiccant and an oxygen detection agent to the inner surface of the packaging bag, and a method for attaching the sachet.

  In a packaging bag in which foods such as confectionery and ramen are contained, an oxygen scavenger and a desiccant enclosed in a sachet are stored in order to maintain the freshness of the foods. When the sachet is not fixed to the packaging bag, for example, when the food is taken out of the packaging bag and transferred to the cooking container, there is a possibility that the sachet is put together and cooked as it is. In addition, it is said that an accident occurs in which an infant mistakes an oxygen scavenger or desiccant in a sachet as a confectionery and eats it. Further, since the location of the sachet put into the packaging bag is not constant, it is difficult to detect that the sachet is put in the packaging process.

  In order to eliminate such troubles, a method of fixing a small bag to a packaging bag has been proposed. For example, in “vertical bag making filling and packaging apparatus and packaging method” of JP-A-10-305818, a freshness holder is automatically fixed inside a packaging bag formed continuously from a sheet-shaped packaging material. The technical contents to be disclosed are disclosed.

  According to the contents described in the above-mentioned published patent gazette, the packaging bag is formed from the sheet-shaped packaging material in which the sachets are fixed at appropriate intervals in advance. On the other hand, the “sticking device” of Japanese Patent Application Laid-Open No. 2001-171896 discloses the technical content of sticking a freshness holding body to the inner surface of a packaging bag formed in advance in a bag shape via an adhesive layer.

Further, the latter publication discloses a method in which oxygen detection paper is attached to one side of a belt-like body in which sachets are continuously formed, and then the sachets separated into one unit are attached to a packaging bag. However, in this method, since the oxygen detection paper is pasted within the outline of the small bag, it is not always easy to detect the oxygen detection paper stuck in the packaging bag with a photoelectric sensor or a monitoring camera. I think that the.
