Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing a refill liquid for refilling a container such as a pump container.

[0002]

2. Description of the Related Art Conventionally, shampoos, body soaps,
2. Description of the Related Art Pump-type containers that discharge a suitable amount of liquid such as dishwashing detergent with a pump when used are often used. And in recent years,
Due to resource savings, even if the contents of the pump-type container are exhausted,
The container is refilled with a new liquid without discarding, that is, the contents are refilled and reused many times.

[0003] Various types of containers for storing the refilling liquid are known. As one of them, there has been known one in which a spout for discharging a liquid is constituted by a pipe. That is, for refilling, the periphery of two synthetic resin films on the front and back is sealed, and a protruding spout with a hard or semi-rigid pipe embedded between the two synthetic resin films on the front and back is provided in part of the periphery. Liquid storage containers have been proposed.

FIG. 3 shows an example of the conventional refillable liquid storage container, and is a front view showing a state where the liquid is filled and sealed. Reference numeral 1 denotes a sealing portion which seals the periphery of the refillable liquid storage container, which is indicated by oblique lines. Numeral 2 denotes a protrusion forming a pouring portion. The protruding pouring portion 2 has a semi-rigid or hard pipe 3 inserted between a front film and a back film,
It has a structure in which the entire protrusion-like pouring portion is bonded and the pipe 3 is embedded. Reference numeral 4 denotes a spout of the pipe 3. FIG. 4 is a cross-sectional view of the protruding spout 2 of FIG. 3 taken along line AA. The pipe 3 is fixed by bonding the front film 5 and the back film 6, and seal portions 7, 8 are present on both sides of the pipe 3 in a fin shape.

In order to transfer the liquid contained in the refilling liquid storage container shown in FIG. 3 to the pump type container, the location of the line AA of the protruding pouring portion 2 of the refilling liquid storage container is to be scissored. Cut with a cutting instrument such as to cut off the seal portion 9 at the tip end,
The spout 4 of the pipe 3 is exposed, and then the projecting spout 2
Is inserted into the mouth of the pump type container with the fin-shaped seals 7 and 8 attached, and the refilling liquid storage container is tilted to discharge the liquid inside.

[0006]

As described above, in order to transfer the liquid content from the conventional refill liquid storage container to the pump type container, the projecting pour-out portion 2 of the refill liquid storage container is used.
Since the A-A line portion of the above must be cut with a cutting instrument such as scissors, this transfer requires a cutting instrument, which is inconvenient. An object of the present invention is to provide a refilling liquid storage container in which the spout 4 of the pipe 3 is exposed without using such a cutting tool and the liquid content can be transferred to a pump-type container. . It is another object of the present invention to provide a refillable liquid storage container in which the liquid content can be transferred to a pump-type container in a plurality of times.

[0007]

Means for Solving the Problems That is, according to the present invention, the periphery of two synthetic resin films on the front and back is sealed, and a protrusion-like spout is provided at a part of the periphery, and the front and back of the two synthetic resin films are provided. In a refilling liquid storage container in which a semi-rigid or rigid pipe fixed between synthetic resin films is embedded, a lid member is rotatably fitted to the tip end portion of the pipe, and a sealing portion is provided on a side portion of the pipe. A refilling liquid storage container having an opening notch.

The refill liquid storage container of the present invention will be described with reference to FIG. 1 showing an example thereof. FIG. 1 is a front view showing a state in which a liquid storage container for refilling of the present invention is filled and filled with liquid,
The enlarged projection portion is shown. Reference numeral 1 denotes a sealing portion which seals the periphery of the refillable liquid storage container, which is indicated by oblique lines. Numeral 2 denotes a projection forming a spout. The projecting pour-out portion 2 has a structure in which a semi-rigid or semi-rigid pipe 3 is inserted between the front surface film and the back surface film, the entire projecting pour-out portion is sealed, and the pipe 3 is embedded. Reference numeral 12 is a lid member rotatably fitted to the tip of the pipe 3. Reference numerals 10 and 11 are notches for opening provided in the seal portions 7 and 8. The opening notches 10 and 11 may be provided only on one side of the seal portions 7 and 8. The opening notches 10 and 11 are provided so as to be located next to the tip of the pipe 3 as much as possible. The shape of the lid member 12 in the present invention may be any shape as long as it can be rotatably fitted to the tip portion of the pipe 3, and the shape is arbitrary. In this example, a solid lid member having a trapezoidal vertical cross section (that is, a frustoconical solid lid member).
Although the thin portion was inserted into the pipe 3 and fitted therein, a lid member having a T-shaped vertical section, a solid member, a hollow member, or a member having a through hole may be used. Good.

Then, in order to transfer the liquid content from the refill liquid storage container of the above example to another container such as a pump type container, the protrusion-shaped pouring portion 2 of the refill liquid storage container is used. Using the opening notch 10 or 11 provided in the above, the seal portions 7 and 8 are torn by hand to the pipe 3, and then the tip seal portion 9 of the projecting pour-out portion 2 is twisted by hand to be cut off. When the pipe 3 is buried as it is, since the pipe 3 is integrally sealed by the seal portions 7 and 8 on both sides thereof and the seal portion 9 at the tip, even if the notches 10 and 11 for opening are opened.
It is difficult to twist and separate the tip seal portion 9 even if the seal portions 7 and 8 are cut up to the pipe 3 by hand by utilizing. However, in the present invention, the lid member 12 is present at the tip of the pipe 3, the pipe 3 is integrated with the seal portions 7 and 8, and the lid member 12 is integrated with the seal portion 9 at the tip portion. Since the lid member 12 is rotatably fitted to the pipe 3, the lid member 12 can be rotated with respect to the pipe 3. That is, a twist can be imparted to the container-constituting film of the seal portion. Then, by this twisting, the seal portion 9 can be easily twisted off from the seal portions 7 and 8 and separated. At this time, the lid member 12
Is also separated from the tip of the pipe 3 and is removed together with the seal 9 at the tip.

FIG. 2 shows a state in which the seal portion 9 and the lid member 12 are cut off and removed to expose the tip portion of the pipe 3. Reference numeral 4 denotes the exposed tip portion of the pipe 3, which serves as a spout when pouring out the liquid content. The exposed spout 4 is inserted into the injection port of the pump type container, and the refilling liquid storage container is tilted to discharge the liquid inside the pump type container.
In this way, the liquid content can be transferred from the refill liquid storage container to another container by using only the hand without using a cutting instrument such as scissors. Then, when the content liquid cannot be completely transferred from the refilling liquid storage container to the pump-type container and the content liquid remains in the container, the lid member 12 removed from the tip of the pipe 3 is piped again. It can be fitted to the tip of 3 to form a stopper to store the liquid content.

The liquid container for refilling of the present invention is made of a conventionally used material such as biaxially oriented polypropylene film, biaxially oriented polyamide film, biaxially oriented polyester film, ethylene-vinyl alcohol copolymer film and the like. A composite film in which various films are used as base materials, and olefin-based heat-adhesive resins such as low-density polyethylene, linear low-density polyethylene, ethylene-vinyl acetate copolymer, and polypropylene are laminated as a sealant layer on these base material films. Is used. In this case, a plurality of the above-mentioned various films may be laminated on the substrate in order to enhance the protection of the contents, and further, an aluminum foil may be used. The shape of the container is arbitrary, but a standing pouch is preferable.

As a semi-rigid or rigid pipe,
Molded from high-density polyethylene, polypropylene, polyvinyl chloride, etc. The outer diameter and the inner diameter of this pipe are usually 3 to 20 mm, depending on the size of the inner diameter of the injection port of the container to which the contents are transferred. The thickness of the pipe wall is preferably 0.5 to 1.5 mm. Also, the lid member is
It is manufactured by molding synthetic resin such as high-density polyethylene, polypropylene, and polyvinyl chloride. When the lid member is a truncated cone as in the above example, the diameter of the large surface is larger than the diameter of the pipe, and the diameter of the small surface is smaller than the diameter of the pipe.

[0013]

In the liquid container for refilling of the present invention, a lid member is rotatably fitted to the tip of a pipe embedded between two synthetic resin films on the front and back of the spout, and the pipe is Since the notch for opening is provided in the seal part on the side,
When transferring the content liquid from this refilling liquid storage container to another container such as a pump-type container, you do not have to use a cutting tool such as a pliers as in conventional containers of this type, but simply It is convenient because the spout can be exposed easily and smoothly. In addition, when the liquid content in the refilling liquid storage container cannot be completely transferred to another container such as a pump type container and the liquid content remains in the container, the lid member is refitted to the tip of the pipe. There is also an advantage that it can be saved.
