[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bag-in-bag having a handle function for use in liquid contents of foods and non-foods.
It is about a box.

[0002]

2. Description of the Related Art Recently, a liquid paper container having a structure in which a plastic bag is housed in an inner bag called a bag-in-box has been used for non-food-related products such as liquid detergents and softeners, alcoholic beverages, and fruit juices. It has been widely used in foods such as beverages. This container is 0.9 liters for general consumers,
Small and medium-sized ones such as 1.8 liters and 3.6 liters were used.

Conventionally, the surface of a paperboard outer box is printed with a pattern, a character, or the like, and an overcoat varnish or the like for protecting the printing surface is applied thereon. Since the bag-in-box containing the contents is relatively heavy, usually 1 kg to 2 kg, the outer surface of the bag-in-box slips when handling with one hand at the time of dispensing the contents, so that it may be difficult to handle. .

[0004]

Therefore, as a method for improving the handling by one hand when using the bag-in-box, a method using a handle is disclosed in Japanese Utility Model Laid-Open No. 60-193059. But this is
The other handle part was inserted and locked in a handle through slot provided in the outer box.

In the present invention, a handle function is provided to a bag-in-box itself by providing cuts and / or ruled lines in an outer box made of paperboard without using other handle parts.

[0006]

The present invention is shown in FIGS.
As shown in the figure, in a bag-in-box in which a plastic inner bag (52) is stored in a paperboard outer box (51), each of the two side plates (12, 14) of the outer box is provided. , at any position opposing the back plate from an arbitrary position of the lower back plate side through the vertical ruled lines (11), next to two notches (61 and 63, 62 and 64) provided, and it
A back plate (11) facing each side plate (12, 14)
A bag having a grip function provided with vertical ruled lines (65 and 66, 67 and 68) connecting both ends of two cuts on both sides.
The in box (50).

The cuts and ruled lines provided in the side plate and the back plate of the present invention are not used at the time of distribution but are folded for the first time when the contents are poured out to form a handle portion.

[0008] The cut of the present invention may be provided with a joint as needed in preparation for distribution.

[0009] The adhesive margin piece to be attached to the side plate is provided with a cut at a position corresponding to the cut of the present invention provided on the side plate.

[0010] The shape of the bag-in-box of the present invention may be a rectangular parallelepiped shape other than a seven-sided shape in which the upper ridge of a rectangular parallelepiped which will be described in detail in an embodiment to be described later is cut off obliquely.

[0011]

When the contents are poured out, the folds formed by the cuts and the ruled lines of the present invention provided on the side plate and the back plate are pushed into the inside of the container, and are sandwiched between the two folds and the folds. A convex handle is formed by the rear plate. By grasping this handle with your hand, you can hold the bag-in-box firmly.

[0012]

FIG. 1 shows a bag used in an embodiment of the present invention.
It is the side view which cut out some in boxes. FIG.
FIG. 4 is a development view of a blank plate of an outer box of the bag-in-box of the present invention. Next, the present invention will be described in detail with reference to the drawings.

First, as shown in FIG. 2, a blank for forming the outer wall (1) of the outer box is provided on a blank plate for manufacturing the outer box of the bag-in-box of the present invention. 1
5), back plate (11), side plate (12), front plate (1
3) and the side plate (14) are connected to each other via vertical ruled lines, and an inclined plate (16) having a cutout (26) at the center of the front plate, through which a spout is projected, is provided horizontally. The triangular folds (32, 33) are formed at the upper corners adjacent to each other through the inclined plates of the two side plates (12, 14) and the vertical ruled lines. Provided through. The two triangular folds are provided with cutouts (29, 31) for facilitating the fold, cutouts (27, 28) not to hit the spout at the time of the fold, and oblique ruled lines for the fold. Was. Further, in order to form the top sealing plate group (2) of the outer box, a flap (1) is formed at the upper end of the back plate and the inclined plate.
9, 21) on the top of the two side plates (17, 1).
8) are connected to each other via horizontal ruled lines, and flaps (24, 25) are provided at the lower ends of the back plate and the front plate to form a bottom sealing plate group (3) of the outer box. Bottom plates (22, 23) were respectively connected to the lower ends of the two side plates via horizontal ruled lines. Finally, the two side plates (12,
In each of the above 14), an arbitrary position on the back plate (11) opposite from an arbitrary position on the lower back plate side via a vertical ruled line
A parallel horizontal cut (61 and 63, 62 and 64) of the book is provided, and a vertical ruled line (65) connecting both ends of the two cuts.
And 66, 67 and 68) were provided for each.

Next, the produced blank plate, inner bag and spout were assembled to produce the 1.8-liter bag-in-box shown in FIG. In this assembly,
As shown in FIG. 3, the entire surface (4
1) and the upper (42, 43) and lower (4)
4 and 45), the inner bag was partially adhered to avoid the folded portion forming the handle.

[0015] The bag-in-box of the present invention was filled with water, and the folded portion was pushed into the inside of the container to form a convex handle portion. There was no slippage on the surface and difficult handling.

[0016]

[Effect of the Invention] When the bag-in-box of the present invention is used, when the contents are poured out, a convex handle portion is formed by the cuts and ruled lines of the present invention provided on the side plate and the back plate. Is formed, there is no danger that the hand slips on the surface of the outer box, making it difficult to handle, or dropping the bag-in-box on the floor.
