DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail. The refillable container of the present invention includes a pouch made of a synthetic resin film, a storage container capable of storing and removing the pouch and having a thread provided on an outer periphery of a mouth and neck thereof, a crimping member, and a crimping member. It consists of a cap that closes the formed through hole. A major feature of the refillable container of the present invention is that the top of the mouth and neck of the storage container is covered with a synthetic resin film disposed near the opening of the pouch, and this is covered with the outer periphery of the mouth and neck of the storage container. The structure is such that the structure is fixed by crimping with a crimping member having a screw thread to be screwed into the screw thread provided in the above. With such a structure, the refillable container of the present invention can complete required work without transferring contents in the pouch at the time of refilling work. Furthermore, a bulky and simple pouch can be used.

Next, the structure of the refillable container of the present invention will be clarified by describing a procedure for performing a refilling operation using the container. 1 to 4 are schematic cross-sectional views for explaining a procedure of a refilling operation using the refillable container 1 of the present invention. First, in FIG. 1, the storage container 3 is divided into upper and lower portions, and among the divided storage containers 3, the pouch 2 is stored and opened in the lower storage container, and the opening 21 is formed. ).

Next, in FIG. 2, of the storage containers 3 divided into upper and lower portions in FIG. 1, the upper storage container and the lower storage container are engaged. Here, the opening 2 of the pouch 2
Numeral 1 is penetrated through the mouth and neck 31 of the storage container 3 and further folded outward so as to cover the top of the mouth and neck 31 of the storage container (procedure 2). In addition, in this figure, although the example which divided the storage container into upper and lower parts and engaged by the engagement protrusion 33 was shown, it is only an example, and the method of engaging with a screw may be sufficient, and the hinge part may be used. A system which can be opened and closed in a provided hatch system or another system may be used.

Finally, in FIG. 3, the storage container 3 in FIG.
The synthetic resin film covering the top of the mouth-and-neck portion 31 is pressed by the pressing member 4 to fix the pouch 2 and the storage container 3. That is, the screw thread 32 provided on the outer periphery of the mouth and neck portion of the storage container 3 and the screw thread 42 provided on the crimping member 4 are screwed together, and the pouch 2 and the storage container 3 are brought into contact with each other by this tightening strength. The part is firmly crimped and fixed (procedure 3). In the example shown in FIG. 3, the packing 43 is attached to the crimping member 4 at a position corresponding to a portion where the pouch 2 and the storage container 3 are in contact with each other.
By attaching the packing in this way, the sealing property at the position is improved, and it is particularly preferable when the contents are liquid. The packing may be attached to the top of the mouth and neck of the storage container 3 or may be attached to both the crimping member and the top of the mouth and neck of the storage container.

A cap 5 is attached to the upper part of the crimping member 4 to close a through hole 41 formed in the crimping member. The cap is not limited to the form as shown in FIG. 3. For example, when the content is a liquid such as shampoo, a pump 51 as shown in FIG. 4 may be attached.

Next, the pouch 2 used in the refillable container of the present invention will be described. In the pouch used in the present invention, the opening formed by opening the pouch penetrates the mouth and neck of the storage container, and the synthetic resin film disposed near the opening covers the top of the mouth and neck of the storage container. Any form can be used as long as it is possible. The synthetic resin film constituting the pouch is appropriately selected according to the properties of the contents to be filled in the pouch, but from the viewpoint that refilling can be performed more easily.
The synthetic resin film disposed near the opening of the pouch is preferably soft. More specifically, the average stiffness of the synthetic resin film arranged in the vicinity of the opening of the pouch measured using a stiffness tester is 2.0 g or less in the MD and TD directions, and more preferably 1 g or less. 0.0g or less is desirable. The stiffness here refers to a load when a sample is crushed by 5 mm using a stiffness tester manufactured by Toyo Seiki Seisaku-Sho, Ltd. under the conditions of a sample distortion angle of 10 ° and a load cell moving speed of 0.5 mm / sec. . 5 to 7 show examples of the form of the pouch usable in the present invention. The pouches shown in FIGS. 5 and 6 are obtained by simply heat-sealing a tube-shaped film, and have a structure in which the upper portion is narrowed so as to easily penetrate the mouth and neck of the storage container. The pouch shown in FIG. 7 has a basic structure of a self-standing bag, a so-called standing pouch, and is made of a relatively rigid laminated film. A tube having a width smaller than that of the pouch body is attached to an upper portion thereof so as to easily penetrate the mouth and neck of the storage container. As described above, it is desirable that the tube is made of a softer material, specifically, a tube having a stiffness value of 2.0 g or less on average in the MD and TD directions.
