[Problems to be solved by the device]

 However, in the conventional refill container, the contents are transferred from the container of the refilled contents to the container body, or the container of the refilled contents is completely stored in the container body and used in a sealed state. For this reason, in the former container, the contents could be spilled outside the container or the hands could be soiled during transfer, or the entire contents could not be transferred and remained. In the latter container, when used in a humid place such as a bathroom or kitchen, the container of the refill contents stored in the container body may be moldy due to the moisture in the container body. The present invention solves the above-mentioned problems of the conventional refill container, prevents the inconvenience at the time of refilling the contents, prevents the mold from generating mold, and has a very simple container structure. Is provided.

[0004]

[Means for Solving the Problems]

 As shown in FIG. 1, the present invention provides a standing pouch (120) with a spout containing refill contents, a support (110) for holding the pouch, and a spout (121) for the pouch. A refill container comprising a cap (131) to be attached, wherein a cap is attached to the spout of the pouch inserted into the insertion hole (116) of the top plate (112) of the support, and a base ring ( 123), a refill container (110) for fixing the pouch to the top plate by sandwiching the top plate of the support with a cap or the upper edge of the pouch, and for holding the side wall of the support by partially covering the pouch. ).

The above-mentioned support is formed by injection molding or sheet molding using polypropylene, polystyrene, polyethylene, etc., and includes a front plate, a top plate, and a front plate in Examples 1 and 2 to be described later. The fold line formed at the boundary between the back plate and the bottom plate may be formed at the same time as the molding, or may be heated after the molding for secondary processing. Also, when the material is polypropylene, it is also possible to give hinge properties to the necessary folds.

A standing pouch with a spout is a flexible packaging body obtained by heat-sealing a spouting member made of polyethylene or polypropylene molded by an injection molding method, and the flexible packaging body is made up of a content and a container. Depending on the purpose, it is manufactured in the form of a self-supporting bag with a bottom gusset, using a plastic single-layer film or a composite packaging material in which a plastic film is laminated with paper or aluminum foil.

The width of the spout insertion hole formed in the top plate is smaller than the outer diameter of the pedestal ring of the pouch spout and larger than the inner diameter.

In addition to the general cap, the standing pouch of the refill container of the present invention has a dispenser having a special function (a dispenser capable of extracting an appropriate amount by a pump system), a cap with a snap hinge (one operation) in addition to a general cap. A cap that opens and closes with a lid) may be selected and used according to the purpose of use of the container. Is provided.

In addition, when the container needs strength during use, a reinforcing rib or a reinforcing plate may be provided at an appropriate position of the support, if necessary.

[0010]

[Action]

 Remove the cap of the spout of the standing pouch containing the contents for refilling, for example, as shown in FIG. 1, the insertion hole (116) of the top plate (112) of the support of the refill container (110) of the present invention. Insert the upper part from the pedestal ring (123) of the spout, and attach the cap (131) suitable for the intended use of the container to the spout, and the pedestal ring of the spout and the cap will support the top of the support. The face plate is firmly attached, and the pouch is fixed to the top plate and fixed to the support.

Since the standing pouch containing the contents for refilling is mounted in a rigid and solid support body, even if a cap that is subject to external force during use, for example, a dispenser is used, the pouch can be attached to the support body. Reinforced by rigidity, it prevents the pouch from being crushed by external force during use.

Since the refill container of the present invention is used in high temperature and humidity, for example, in a bathroom, etc., the support body with the standing pouch is partially covered with the pouch and is not in a sealed state. Good ventilation. For this reason, moisture does not accumulate between the support and the pouch, so that mold is unlikely to grow on the inner surface of the support and the outer surface of the pouch. In addition, since the pouch stored can be seen through the gap between the supports, if a transparent or translucent pouch is used, the remaining amount of the contents in the pouch can be easily confirmed from the outside of the container. .

FIG. 1C is a perspective view of the container, and FIG. 1C is a cross-sectional view near the spout of the refill container.

First, using polypropylene, an ordinary injection molding method was used to produce a rectangular parallelepiped support of the present embodiment shown in FIG. 1A, which was composed of a front plate, side plates, a back plate, and a top plate. did. The top side of the front plate is separated from the top plate.One side of the front plate has a fold line at the boundary with the side plate, and the top side of the front plate is inserted into the insertion hole of the top plate. A locking piece with a locking projection for fixing the pouch spout was provided through the fold. In addition, the fold line at the boundary between the front plate and the side plate and the fold line at the boundary between the front plate and the locking piece were given a hinge property by heat treatment and bending after molding.

Next, the pouring spout of the standing pouch was produced by using polyethylene by an injection molding method. On the side wall of this spout, a male screw was formed to be screwed with the "dispenser" of the ready-made cap to be used. Separately, polyethylene (PE) is laminated by an extrusion lamination method using unstretched polypropylene film (CPP) and polyethylene terephthalate (PET) to produce a laminated film having a CPP / PE / PET / PE structure. Then, this laminated film was made into a bag to prepare a bottom gusset type flexible package having an open upper side. Then, the pouring outlet prepared above was heat-sealed by an ultrasonic sealing method to the opening of the upper side of this flexible package to prepare a standing pouch of this example. The prepared standing pouch was filled with the content, and the outlet was fitted with a normal cap and sealed.

Next, as shown in FIG. 1, the cap (130) of the standing pouch accommodating the produced contents was removed, and the upper part of the pouch outlet pedestal ring was inserted into the insertion hole of the top plate of the support. Then, the dispenser (131) with a ready-made cap is attached to the spout by screwing the female screw (132) and the male screw (122), and the top plate of the support is attached by the pedestal ring of the spout and the cap. After fixing the pouch to the top plate by sandwiching it, close the front side of the support so that the front plate covers the pouch, and attach the locking protrusion of the locking piece on the top side of the front plate to the top plate. The refill container (100) of this example was manufactured by inserting the support into the insertion hole of the above. The pouch was tightly housed in the support and the dispensing head of the dispenser was actuated up and down to dispense all the contents in the pouch, but the pouch is reinforced by the rigidity of the support. It didn't collapse. Next, the empty pouch was detached from the support, and the pouch containing the new refill contents was attached again. The operation of attaching and detaching the pouch to the support and attaching it were very easy, and , I didn't get my hands dirty during operation. Furthermore, when used in a hot and humid bathroom, the air permeability between the support and the pouch was good.
