Description

  The present invention relates to a storage box and a storage body for storing a non-self-supporting bag-like container made of a soft packaging material, having a mouth portion at the top, and filled with a liquid material.

  In recent years, bag-like containers with spouts made of film have been reduced in terms of waste, disposal, and portability in the fields of food and beverage containers, toiletries containers, and medical containers due to environmental issues and convenience of handling. Due to the convenience of handling such as not being broken, the number of bag-like containers made of plastic films has been increasing.

  The bag-like container can be easily folded into a flat shape after the contents are taken out, and has the advantage of not being bulky when disposed of. Because it cannot be used, its use is limited. For example, since the container must be stored in a laid state, it has not been suitable for applications in which liquid substances such as liquid beverages, liquid foods, and liquid detergents are dispensed. In addition, when the product is transported, pressure is applied to the mouth due to vibration, etc., and even when packing, the container is stacked and stored in the outer box, so that the storage part can be damaged by rubbing and malfunction such as liquid leakage can occur. It is known that it will occur, and the cost is low, but it is not used much.

  As these measures, as a liquid packaging container of liquid or gel-like body, a plastic film bag-like container is stuck on a paper outer box such as cardboard or carton, and the bag-like container is filled with liquid. There is known a self-supporting composite container that is produced by raising the outer box. A back-in box, a back-in carton, is known. (For example, see Patent Document 1). In addition, a bag-like container can be stored independently, regardless of the amount of contents, and an outer case of the bag-like container is known (see, for example, Patent Document 2).

  The container described in Patent Document 1 can be provided with functions such as gas barrier properties, water vapor barrier properties, and light shielding properties depending on the material configuration of the interior bag, and the rigidity of the exterior box allows for handling and storage during transportation. It is excellent that it can withstand stresses such as vibrations and shocks from the outside. However, when it is discarded after use, the container must be peeled from the outer box, and such a composite container is produced. It has the problem that it is expensive to do.

  The technique described in Patent Document 2 is excellent for using up the contents of the bag-like container, but can withstand stresses such as external vibration and impact during handling and storage in the outer case. Therefore, another measure is required at the time of transportation, and the production of the outer case has a problem that costs are high.

From such a situation, it is made of soft packaging material, has a mouth part at the top, protects the contents of a non-self-supporting bag-like container filled with liquid material, prevents liquid leakage from the mouth part, Development of storage boxes and storage bodies that facilitate transport is desired.
