Device for attaching fresh oil to food package

The present invention relates to an apparatus for attaching a small bag of freshness holding agent to a foodstuff packaging. More specifically, for example, by fixing a small bag of fresh oil holding agent in a package of food products such as confectionery, coffee, sulfur, cereal flour, beans, rice, rice cake, ramen, ham, sausage or delicacy, The present invention relates to an apparatus for packing foodstuffs by attaching a small bag of freshness holding agent to the inner surface of a sieve.

Conventionally, the freshness-retaining agent of foodstuffs exemplified by an oxygen scavenger, a desiccant, etc. takes the form of a small bag, and is usually stored in a packaging bag together with a preserved substance such as foodstuffs without fixing the small bag. It was only.

In the following, a small bag of freshness holding agent is simply referred to as freshness holding agent.

As described above, since the conventional freshness retaining agent is not fixed, when a consumer opens the packaging bag, the freshness retaining agent may be mistaken for foods (hereinafter, the foods may be simply referred to as food), or the freshness retaining agent may be used. In the case of industrial handling, in the case of the opening work of preserved foods, the leading maintenance agent was introduced into the processing equipment together with the food, causing problems. For example, as in the case of coffee beans, Kita, etc., the fresh keeping agent is put into the grinder together with the preserved food, and the deoxidant may be crushed or cooked together.

For this reason, the fixing of the fresh keeping agent to the packaging bag has been considered. For example, a method of narrowing the seal portion of the freshness holding agent to the seal portion of the packaging bag has been examined. However, this method creates a step in the seal portion of the packaging bag, and the seal strength is weak and airtightness may not be maintained since it cannot be pressurized evenly during sealing.

In the case of using a packaging machine such as a horizontal pillow packing machine, a cup sealer packing machine, or a head bag system, an adhesive is added to the leading oil holding agent or a hot melt agent is added and the adhesive is directly fixed to the inner surface of the package. Although the method is simple, the work has conventionally had to rely on manual operation, and automation is impossible.

The present invention, in view of the above-described problems of the prior art, in particular, in the case of automating the packaging of food products using a packaging machine such as a horizontal pillow packing machine or curl sealer packing machine, even the automation of fixing the freshness holding agent to the package is possible. Therefore, the technical problem is that the consumer does not eat the lead maintenance agent by mistake and does not cause a problem caused by the incorporation of the lead maintenance agent during food handling.
