[Industrial applications]

 The present invention relates to a packaging container for packaging liquid, powder and the like.

[0002]

[Prior art]

 Conventionally, liquids and powders such as commercial detergents spill out through small gaps, so they can be transported or stored in hard sealed containers such as bottles made of glass or synthetic resin or metal cans. There is.

Since these containers cannot be folded, there is a problem that the storage space becomes large and the containers become bulky and expensive at the time of transportation, and at the time of disposal, it is necessary to separate and dispose of from general waste. I have a problem.

As a method of solving these problems, the contents are enclosed in a bag made of, for example, a synthetic resin or a composite material obtained by laminating a synthetic resin and a metal foil, and the contents together with the bag are corrugated cardboard or paperboard. There is a method of packing in a paper outer box such as.

[0005]

[Problems to be solved by the device]

 However, this method often causes the bag to slip off from the outer box when the outer box is tilted to a large extent.Therefore, if you want to remove the entire contents, either remove the bag from the outer box or put the bag together with the outer box. There is a problem that workability is poor because it is difficult to grasp.

Particularly, when the weight of the contents is 15 to 20 kg, the workability is not only deteriorated, but when the outer boxes storing the contents are stacked, the weight of the upper package causes the lower outer package to be stacked. The box may crush and in some cases the bag may burst causing the contents to dissipate around.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a packaging container that can be disposed of together with general combustible waste.

[0008]

[Problems to be solved by the device]

 In order to achieve the above-mentioned object, the present invention has an outer box made of corrugated board, a middle frame made of corrugated board provided along the inner surface of the peripheral wall of the outer box, and one side surface of the middle frame. It has an inner lid that is bent upward on the side surface and a synthetic resin bag that is housed in the inner frame.The outer box and the inner frame are fixed to each other, and the bag is bonded to the inner frame. It is characterized by being

[Work]

 Since the packaging container of the present invention comprises the outer box made of corrugated board, the inner frame made of corrugated board, and the bag, it can be folded and stored or transported.

In addition, it has a cardboard middle frame provided along the inner surface of the peripheral wall of the outer box, and an inner lid that is continuous with one side surface of the middle frame and is bent to the upper side of each side surface of the middle frame. Therefore, the strength against the pressure from above increases.

Furthermore, since the inner frame is fixed to the outer box and the bag is fixed to the inner frame, the inner frame and the bag are not likely to slip off the outer box even if the outer box is largely tilted, and the outer box is held. The entire amount of the contents can be taken out easily just by tilting.

In addition, since the outer box made of corrugated board, the inner frame made of corrugated board, and the bag are configured, it can be disposed of together with general combustible materials.

In the present invention, the structure of the bottom of the outer box is not particularly limited, but it is possible to simplify the packaging work and reduce the working time by adopting a folding bottom or an adhesive folding bottom that can be directly folded when packaging. It is advantageous in shortening the

【Example】

 A packaging container according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view of a liquid detergent packaging container according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof. As shown in these drawings, the packaging container includes an outer box 1 made of corrugated board, a middle frame 2 made of corrugated board, and a bag 3.

The type of corrugated cardboard corrugating the outer box 1 is not particularly limited, but in this embodiment, A-flute corrugated corrugated cardboard, which is particularly excellent in flat pressure and parallel pressure, is used, and the vertical pressure in the corrugated direction is increased in the peripheral wall portion. It is shaped to work. In addition, as the structure of corrugated board, it is possible to use double-sided corrugated board (double wall) which is excellent in strength and double-sided corrugated board (tri-wall) which is further excellent in strength. It is easy and uses a commonly used double-sided ball structure. Releasing and single-faced corrugated board are not suitable because of problems in strength.

The shape of the outer box 1 is not particularly limited, and it is possible to form it into a special shape such as a cylinder, an elliptic cylinder shape, or a heart shape. However, in this embodiment, a cubic shape which is easy to manufacture is used. It has a box shape.

Further, the structure of the bottom of the outer box 1 is not particularly limited, but here, as shown in the bottom view of FIG. 3, it can be folded along the folding line 4, and if folding is performed during packaging. In order to open the bottom as it is, for example, an automatic bottom-type automatic bottom applicator is used to fold the four bottom flaps 5 so that they can be folded into an adhesive folding bottom (hell bottom) that is adhered to each other.

The form of the upper lid of the exterior box 1 is not particularly limited, and a form such as a butt cut type (A type), a plug type (B type), a cover box (C type), or the like can be adopted. However, in this embodiment, the butt cut type which is strong in strength and is generally most used for the exterior is adopted.

The middle frame 2 is formed in a tubular shape having a size inscribed in the four side walls of the outer box 1, and like the outer box 1, it is possible to use A-flute corrugated cardboard, but the cost is reduced. Therefore, B-flute cardboard is used. The vertical direction is applied to each side wall as the direction of the mold. Further, the inner lid 6 extends from the upper end of one side wall of the inner frame 2, and the remaining three edges of the inner lid 6 are received by the upper ends of the other side walls of the inner frame 2, respectively.

The middle frame 2 is inserted into the outer box 1 and fixed to the outer box 1. Although the side walls of the middle frame 2 and the outer box 1 may be fixed to each other, in order to improve workability during packaging and unpacking, the inner lid 6 connected to the middle frame 2 and the upper lid of the outer box 1 are connected. It is preferable that one of the middle flaps 7 is fixed.

The inner frame 2 and the outer box 1 may be fixed to each other by, for example, stapling, but in this embodiment, the adhesive 8 is attached to the inner lid 6 in a thick band shape (or a striped shape) by using, for example, an applicator. Then, the inner frame 2 and the outer box 1 are fixed by inserting the inner frame 2 into the outer box 1 and overlapping the inner lid 6 and the middle flap 7 of the upper lid. As the adhesive, an adhesive generally used for bonding corrugated board is used.

The material of the bag 3 may be appropriately selected according to the content, and a synthetic resin sheet, a synthetic resin film, a composite material obtained by laminating a synthetic resin and a metal foil such as an aluminum foil, or the like is used. You can In this embodiment, a bag made of a polyethylene sheet having a thickness of about 150 μm that can be obtained at low cost is used.

The shape and size of the bag 3 are not particularly limited, but in this embodiment, the length of the waistline is substantially the same as the inner peripheral length of the middle frame 2, and the height is higher than that of the middle frame 2 such as a cubic shape. The bag 2 formed in a rectangular shape is used.

The bag 3 may be fixed to the outer frame 1 after the inner frame 2 is fixed to the outer frame 1. However, in order to improve workability, the inner frame 2 is attached to the outer box 1 here. Before being inserted and fixed, the inner frame 2 is fixed by adhesion or adhesion.

The pressure-sensitive adhesive or adhesive for fixing the bag 3 to the inner frame 2 is not particularly limited and may be appropriately selected in consideration of the materials of both.

The bag 3 may be adhered or adhered to the entire inner surface of the middle frame 2 or may be adhered or adhered to the inner surface of the bottom of the outer box 1, but here, for example, 1 Adhesive or adhesive 9 is attached to the shape of a thick strip having a width (height) of about 3 cm by an applicator, for example, and the bag 3 is folded and placed in the inner frame 2 to fold the inner frame 2 and the outer box 1. By this, the bag 3 is pressed against the middle frame 2 and adhered.

Since this packaging container can be thinned by folding it as shown in FIG. 3, for example, it is possible to stack and store a large number of packaging containers in such a folded state, and to store and transport space. Can be made smaller, and storage costs and transportation costs can be reduced.

When the outer box 1 is folded at the time of packaging, the bottom can be easily formed as it is, and the mouth of the bag 3 can be opened naturally. Therefore, the contents can be injected easily and in a short time.

Furthermore, since the peripheral edge of the inner lid 6 is continuous with the upper edge of the inner frame 2 or can receive the load acting on the upper surface, the load acting on the upper lid of the outer box 1 is transmitted via the upper lid. Since it is shared by the four side walls and also by the inner frame 6 through the inner lid 6, a large weight can be supported. For example, a packaging container containing about 15 to 20 kg of contents can be used. The packaging containers will not be crushed even if they are stacked in layers.

In addition, when the contents are taken out, even if the mouth of the bag 3 is opened and the outer box 1 is held and tilted, the middle frame 2 and the bag 3 do not slip out of the outer box 1 and only the contents are removed. Since it can be dropped, it is easy to use and has high workability.

Moreover, since it can be incinerated together with general waste as a combustible material at the time of disposal, the labor for separation is not required.

[Effect of device]

 As described above, the packaging container of the present invention is composed of the outer box made of corrugated cardboard, the inner frame made of corrugated cardboard, and the bag, so that it can be folded and stored or transported. Costs and transportation costs can be reduced.

Further, it has a cardboard middle frame provided along the inner surface of the peripheral wall of the outer box, and an inner lid which is continuous with one side surface of the middle frame and is bent to the upper side of each side surface of the middle frame. Therefore, the strength against pressure from above becomes stronger. For example, by configuring the outer box with A flute corrugated board and the inner frame with B flute corrugated board, it is possible to crush the uncontained 15-20 kg corrugated packaging container. It is possible to stack more than 5 steps without.

Further, since the inner frame is fixed to the outer box and the bag is fixed to the inner frame, the inner frame and the bag are not likely to slip off the outer box even if the outer box is largely tilted, and the outer box is held. The entire amount of the contents can be taken out easily just by tilting.

In the present invention, particularly when adopting a foldable bottom or an adhesive foldable bottom in which the bottom can be directly formed by simply folding the bottom of the outer box, the folded packaging container is folded up during the packaging work. In addition to making the container shape that can store the contents by itself, the mouth of the bag opens naturally, so it is easy to inject the contents into the packaging container and the work time is shortened. You can get the advantage that you can.
