Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouring device attached to a mouth of a refill container.

[0002]

2. Description of the Related Art Liquid products such as shampoos and detergents are sold in a rigid container formed of a plastic material in consideration of standing properties during display and safety against breakage during transportation.

[0003] The plastic rigid container from which the liquid product is taken out has a special shape and cannot be reused as it is, so it is discarded as industrial waste.
Incineration of used plastic rigid containers as industrial waste wastes plastic resources.
Attempts are being made to recycle used plastic rigid containers. As an example, liquid products such as shampoos and detergents are sealed in plastic film bags, sold as refill containers, and purchased users transfer liquid products filled in refill containers to used plastic rigid containers. Thus, a used plastic rigid container is reused.

[0004]

The refill container has a structure in which a liquid product such as a shampoo or a detergent is sealed in a plastic film bag formed of a laminate film, and the plastic film bag is formed of a laminate film. The amount of plastic in the plastic film bag itself is smaller than the amount of plastic in the blow-molded plastic rigid container, and it has the advantage that the selling price is low. However, the plastic rigidity of the liquid product filled in the refill container is used. Transferring to a container is troublesome for the user.

Therefore, a refill container has been developed in which a spout is integrally connected to the mouth of a plastic film bag so that the liquid product filled in the refill container can be easily transferred to a used plastic rigid container. In order to connect the spouting tool to the mouth of the plastic film bag and fill the plastic film bag with the liquid product, a special molding and filling machine is required, which is not practical.

[0006] The refillable container with the spouting tool cannot be reused as it is and is discarded as industrial waste. In this case, the refilling container has a larger amount of plastic than the refilling container without the spouting tool. This is not preferred as the container will be discarded.

The present invention has been made in view of the above points, and a refill container can be used as it is as a liquid storage container, and can be reused by removing it from a used refill container and attaching it to another refill container. An object of the present invention is to provide a filling tool for a refill container.

[0008]

SUMMARY OF THE INVENTION According to the present invention, there is provided a filling device for a refillable container having a screw portion on an outer surface, an inner member mounted on an inner surface of a mouth of the refillable container, and a refillable container having a screw portion on an inner surface.

According to the present invention, there is provided a refill container dispensing tool comprising: an outer member having a screw portion on an inner surface and mounted on an inner surface of a mouth portion of the refill container; and an inner member having a screw portion on an outer surface and screwed to the outer member. The refill container can be used as it is as a liquid storage container, and can be reused by removing it from the used refill container and attaching it to another refill container.

The refill container dispenser of the present invention has an outer member having a screw portion on the inner surface and mounted on the outer surface of the mouth of the refill container, and an inner member having a screw portion on the outer surface and mounted on the inner surface of the mouth portion of the refill container. By having the outer member and the inner member screwed to each other via the mouth film, the refill container can be used as it is as a liquid storage container, removed from the used refill container, and attached to another refill container. Can be reused.

According to the present invention, there is provided a refill container dispenser having a screw portion on an outer surface and a pouring member mounted on an inner surface of a mouth of the refill container, and a screw member on an inner surface mounted on an outer surface of a mouth of the refill container. It has a cap, and is configured by screwing the cap and the spouting member together via the mouth film, so that the refill container can be used as it is as a liquid container, removed from the used refill container, and attached to another refill container Can be reused.

The inner member 4 has a substantially cylindrical overall shape with a tapered lower end, and a longitudinally intermediate portion of an outer surface of the substantially cylindrical shape has a larger diameter than both ends. The screw portion 7 is formed on the inclined surface formed therebetween. The screw portion 7 may be formed on a flat surface having the same diameter from the upper end to the lower end.

The outer member 5 has a pouring portion 8 and a skirt portion 9, and a screw portion 10 to be screwed to the screw portion 7 of the inner member 4 is formed on the inner surface of the skirt portion 9. A screw portion 11 for screwing the lid 6 is formed on the outer surface of the pouring portion 8.

The cover 6 has a dome shape as a whole,
On the inner surface, a screw portion 12 that is screwed to the screw portion 11 of the spout 8 of the outer member 5 is formed. A receiving portion 13 is formed at the top of the dome-shaped inner surface of the lid 6 so that the opening end 8a of the pouring portion 8 of the outer member 5 is fitted.

The refill container 2 is a bag-like container 2a molded from a plastic laminate film.
And a liquid product such as shampoo and detergent or a viscous product such as miso sealed in the bag-shaped container 2a. The encapsulated product may be machine oil or sauce, soy sauce or mentsuyu.

When a standing property is required, the bag-shaped container 2a has, as shown in FIG. 3, a surface portion molded using a plastic laminate film as a material and a gusset portion disposed therebetween. It is a gusset type bag. A small-diameter mouth portion 3 is formed at the upper end of the bag-shaped container 2a. The mouth 3 has a sectional shape of 12
It is set to a rectangle of ２５25 mm × 9〜22 mm. The opening diameter of the opening 3 is set to several types in advance.

The bag-like container 2a is preferably a gusset-type bag, but if necessary, a plastic laminate film may be folded in two to seal three sides, or a side end may be formed at the center of the rear surface. May be a so-called envelope-type bag-like container in which the upper and lower ends are heat-sealed.

The above-mentioned plastic laminate film is
Biaxially stretched nylon (15 microns) / dry lamination or polyethylene lamination / linear low density polyethylene (120
A three-layer structure of polyester film (12 microns) / dry lamination or polyethylene lamination / biaxially stretched nylon (15 microns) / dry lamination or polyethylene lamination / linear low-density polyethylene (120 microns), Polyester film (12 microns) / dry or polyethylene lamination / aluminum foil (7-12 microns) / dry or polyethylene lamination / biaxially stretched nylon (15 microns) / dry or polyethylene lamination / linear low-density polyethylene (120 microns) Polyester film (12 micron) / dry or polyethylene lami / metallized polyester film (12 micron) / dry or polyethylene lamin / linear low density polyethylene It is selected from 5-layer structure of (120 microns).

Next, a method for attaching the spout 1 according to the present invention to the refill container 2 will be described.

First, the end of the mouth 3 of the refill container 2 is cut by a cutting tool (not shown), and as shown in FIG. 4, the inner member 4 is tapered and the mouth 3 is opened at the end. Insert In this case, the outer diameter of the inner member 4 is set so as to substantially correspond to the inner diameter of the mouth portion 3. When the inner member 4 is inserted into the mouth portion 3, the inner member 4 is made of plastic that forms a refill container. It adheres to the inner surface of the mouth 3 by the elastic force of the laminate film.

Next, as shown in FIG. 5, the outer member 5 is placed with the skirt 9 down, and the mouth 3 with the inner member 4 attached thereto.
Of the skirt 9 of the outer member 5 by turning the outer member 5 clockwise.
Is screwed into the screw portion 7 of the inner member via the plastic laminate film of the mouth portion 3. Then, by screwing the lid 6 to the screw portion 11 of the outer member 5, the pouring portion 8 of the pouring tool 1 is formed.
