Description

The present invention relates to a composite container consisting of a flexible packaging bag and a paper outer case, and particularly to a composite container that exhibits excellent functionality as a refill container.

Refillable containers for storing liquids such as shampoo, conditioner, and various detergents are widely used. A refill container is a container that is equipped with a pump, a spout, etc., and is used to replenish only the contents and continue using the container. Most refill containers are packaging bags made of flexible packaging materials, and many are in the form of a so-called standing pouch, which has a bottom surface to allow it to stand on its own on the sales floor.

When transferring the contents from a refill container to the main container, if the contents are highly viscous and take time to dispense, or if the refill container has a large capacity, the refill container made of flexible packaging material may not last long. The refilling operation was not easy.

The flexible packaging storage container described in Patent Document 1 is a container for storing a flexible packaging filled with liquid, powder, granules, etc. in a self-supporting state and preventing the contents from leaking out. be.

The storage container described in Patent Document 1 is a container for storing a non-self-supporting flexible packaging bag in a free-standing state, and is not designed to facilitate the refilling operation of a refillable container. .

The pouch holder described in Patent Document 2 is easy to attach and fix to a pouch having a liquid pouring spout, and it is easy to pour out the liquid, and even when the amount of contents in the pouch decreases, the pouch can be easily poured out. The company claims that it is an inexpensive pouch holder that can be placed in an upright position with the mouth facing upward at all times, and there is no problem with disposal.

Although it is stated that the pouch holder described in Patent Document 2 can be placed in an upright state, it actually does not have a bottom and is not self-supporting, so the contents may be poured out. If it is not removed and remains, it is difficult to deal with it.

Japanese Patent Application Publication No. 10-310172 JP2003-267397A

The problem to be solved by the present invention is that when transferring the contents from a refill container to the main container, the viscosity of the contents is high and it takes time to pour out, or the refill container has a large capacity. To propose a composite container in which the refillable container can be easily held even when refilling is not completed in one go, and the container can be stored in an upright state.

As a means for solving the above problem, the invention according to claim 1 is a composite container comprising a packaging bag for storing a liquid and an outer cylinder covering the packaging bag,
The packaging bag has a bottom that is mountain-folded so that the sealant layers of two laminates having a base film and a sealant layer are facing each other, and the sealant layer of the laminate having the base film and the sealant layer is on the outside. A self-supporting packaging bag formed by inserting a tape between the two laminates and sealing the periphery,
The vertical seal portion on the side opposite to the side where the spout of the packaging bag is present extends widely, and a vertically long handle hole is punched in the vertical seal portion to form a handle;
The outer cylinder has a cylindrical outer cylinder main body made of cardboard and a handle part, the outer cylinder main body has a polygonal cross section that can be deformed in the horizontal direction, and is capable of storing the packaging bag,
The handle portion includes two handle plates extending from the outer cylinder main body,
One handle plate has a punched hole that matches the position of the handle hole of the packaging bag, and the other handle plate reinforces the vertical side of the punched hole and prevents the cross section of the punched hole from being exposed. A protective folding piece is provided through the folded side,
The composite container is characterized in that the two handle plates sandwich and reinforce the handle of the packaging bag from the front and back surfaces thereof.

Since the composite container according to the present invention is composed of a self-supporting packaging bag having a handle and an outer cylinder having a handle portion that reinforces the handle, it is possible to stably perform a pouring operation when replacing the bag. .

Furthermore, in the composite container according to the present invention, the packaging bag may have a resealable spout.

Further, in the composite container according to the present invention, the outer case may have a bottom plate that prevents the packaging bag from falling.

Further, in the composite container according to the present invention, the outer cylinder main body may have a hexagonal cross section.

Furthermore, the composite container according to the present invention may be characterized in that the packaging bag and the outer tube are not bonded together.

A composite container according to the present invention is a composite container consisting of a packaging bag for storing a liquid and an outer cylinder that covers the packaging bag, and the packaging bag has two sheets having a base film and a sealant layer. The sealant layers of the laminate face each other, and the bottom tape, which is mountain-folded so that the sealant layer of the laminate having the base film and the sealant layer is on the outside, is inserted between the two laminates, and the periphery is Since it is a self-supporting packaging bag that is sealed, it has the advantages of a general self-supporting packaging bag. That is, it can be manufactured stably and conventional manufacturing equipment and filling equipment can be used as is.

The vertical seal part on the opposite side of the packaging bag to the side where the spout is present is extended widely, and a vertically long handle hole is punched out to form a handle, while the outer cylinder made of cardboard is connected to the outer cylinder body. It has two handle plates extending from the bag, one handle plate has a punched hole that matches the position of the handle hole of the packaging bag, and the other handle plate reinforces the vertical side of the punched hole. At the same time, a folded piece is provided on the folded side to protect the cross section of the punched hole from being exposed, and the two handle plates sandwich and reinforce the handle of the packaging bag from the front and back sides, so that the handle can be held easily. This makes the dispensing operation at the time of refilling more stable and easier.

In particular, since the folded piece provided through the folded side of the handle plate serves to protect the cross section of the other handle plate, there is no fear of cutting your hand on the cross section of the cardboard, and the handle plate can be handled safely.

Further, since the outer cylinder main body has a polygonal cross section that can be deformed in the horizontal direction, it is possible to crush the packaging bag and squeeze out the contents.

If the packaging bag is equipped with a resealable spout, it can also be used for applications where the bag is not used all at once. For example, when used as a large-capacity refill container, it is possible to refill the container many times and use it continuously. can be stored stably.

When the outer cylinder has a bottom plate that prevents the packaging bag from falling, this effect is particularly effective in the case of a large-capacity packaging bag. That is, the bottom of the packaging bag does not protrude from the outer cylinder and lose its independence.

The cross-sectional shape of the outer cylinder can be any shape as long as it can be deformed in the horizontal direction, but if it is hexagonal, the flat parts face each other symmetrically on the left and right, unlike in the case of a quadrangle or a pentagon. Therefore, there is an advantage that the crushing operation of the packaging bag can be performed very smoothly.

When the packaging bag and the outer cylinder are not bonded together, it is easy to separate the bag when it is disposed of, and it is highly recyclable.

A composite container 1 according to the present invention is a composite container that includes a packaging bag 10 for storing liquid and an outer cylinder 20 that covers the packaging bag 10.

The packaging bag 10 has a bottom that is mountain-folded so that the sealant layers of two laminates having a base film and a sealant layer face each other, and the sealant layer of the laminate having the base film and the sealant layer is on the outside. This is a self-supporting packaging bag made by inserting a tape between the two laminates and sealing the periphery.

The vertical seal part 13 on the side opposite to the side where the spout 11 of the packaging bag 10 is located extends widely, and a vertically long handle hole 14 is punched out in the vertical seal part 13 to form a handle 15. There is.

The outer cylinder 20 has a cylindrical outer cylinder main body 21 made of cardboard and a handle part 22, and the outer cylinder main body 21 has a polygonal cross section that can be deformed in the horizontal direction, and can accommodate the packaging bag 10. . This example has a hexagonal cross section. Polygons that can be deformed in the horizontal direction include squares, diamonds, rectangles, pentagons, hexagons, octagons, etc. other than triangles, but when the spout of the packaging bag is placed at the corner, the left and right A hexagonal shape is most suitable as a shape that can be compressed in a plane.

The handle portion 22 consists of two handle plates 27 and 28 extending from the outer cylinder main body 21, and one handle plate 27 has a punched hole 23 that matches the position of the handle hole 14 of the packaging bag 10. The other handle plate 28 is provided with a folded piece 24 via the folded side 24a, which reinforces the vertical side of the punched hole 23 and protects the cross section of the punched hole 23 from being exposed. The two handle plates 27 and 28 serve to sandwich and reinforce the handle 15 of the packaging bag 10 from its front and back surfaces.

In the composite container 1 shown in FIGS. 1 and 2, a resealable spout 12 is used as the spout 11 of the packaging bag 10. If you want to use up the contents all at once, it doesn't need to be a spout; you can cut the spout tube and use it as a spout, but a resealable spout will save you a lot of money. It can also be used in applications where the contents of the container are divided into several portions, and the characteristics of the composite container of the present invention can be maximized.

Further, in the composite container 1 shown in FIGS. 1 and 2, the outer tube 20 is provided with a bottom plate 25 for preventing the packaging bag 10 from falling. The bottom plate 25 is adhered to the opposing sides of the outer cylinder using adhesive margins 26. By providing the bottom plate 25, it is possible to prevent the bottom of the packaging bag 10 from protruding from the outer tube 20 and impairing its independence.

The bottom plate 25 may be omitted if the capacity of the packaging bag 10 is not particularly large, but it is effective when the packaging bag 10 has a large capacity and does not have sufficient independence.

In many cases, the packaging bag 10 and the outer tube 20 do not need to be fixed to each other by adhesion. This is because the handle 15 of the packaging bag 10 and the handle portion 22 of the outer cylinder 20 are fixed by the folded side 24. Therefore, at the time of disposal, both can be easily separated and disposed of.
