Abstract

PROBLEM TO BE SOLVED: To provide a carton for housing a packaging web having a function for preventing a paper tube from coming out from a time of filling wherein removal of the paper tube is easy. SOLUTION: The carton for housing a packaging web wound around a paper tube P is equipped with a tab 10 which is folded at a folding rule (a) onto an inner flap 7 on a side face to be positioned inside the paper tube P. The rule (a) for folding the tab 10 is placed to be slant to a horizontal direction of the carton. The tab 10 is folded into the paper tube P by a device such as a pin at the time of fitting the paper tube P in the carton, thereby making the tab 10 stand against the inside of the paper tube P.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carton for accommodating a packaging web such as a wrap film, aluminum foil, and cooking paper used for food packaging.

[0002]

2. Description of the Related Art Conventionally, a packaging web of this type is stored in a carton made of paperboard in a state of being wound around a paper tube. In use, a desired length is drawn from the carton and then put into a carton. It is designed to be cut and used by an attached aluminum saw blade member. By the way, when the web is pulled out, the web may jump out of the paper tube due to its momentum or resistance due to close contact between the films, and various attempts have been made to prevent this. For example, there is known a type in which a part of both sides of a carton is pushed in or a part of the carton is cut out and pushed into a hole provided in a side face to hold the paper tube. In addition, there has been put into practical use one that holds a part of the inner flap inward by folding the inner flap inward and hooking the end of the paper tube.

[0003]

Among the former types described in the prior art, various types of the former type have been put to practical use, but the former type has a part pushed in for the purpose of strongly holding the paper tube. There are many things that are difficult to return,
Therefore, there is a case where the paper tube cannot be easily taken out even if the paper tube is taken out and peeled off when the films are rewound. In addition, since the holes are formed on the side surfaces, it is conceivable that the aesthetic appearance of the design may be impaired, and that dust or the like may enter the carton through the holes. Further, at the stage of use by the purchaser, the user must take measures to prevent the paper tube from popping out by using these mechanisms. Some cases have been put to practical use to demonstrate the function of preventing popping out on the filling machine, but this one has a complicated structure, and when the paper tube is taken out due to the unwinding of the web etc. There is a problem that it is difficult to restore.

The present invention has been made in view of the above problems, and has as its object to provide a function of preventing the paper tube from popping out from the time of filling, and to facilitate the removal of the paper tube. An object of the present invention is to provide a packaging web storage carton.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a packaging web storage carton in which a packaging web wound around a paper tube is stored. The provision is made to provide a tongue which is located inside the paper tube. The tongue piece is preferably formed such that the folding rule is arranged obliquely to the horizontal direction of the carton.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below with reference to specific examples. FIG. 1 is a perspective view showing a specific example of a packaging web storage carton according to the present invention, and FIG. 2 is a developed view of a blank forming the carton.

The carton of this example is for a wrap film, and will be described first with reference to the developed view shown in FIG. 2. In FIG. 2, the upper and lower sides of the line AA are the components of the carton body 1 and the lid 2, respectively. is there. The components of the carton main body 1 are formed by connecting a main body rear wall 3, a main body bottom wall 4, a main body front wall 5, and a front wall reinforcing plate 6 sequentially through a folding line.
The inner flaps 7, 7 of the side wall, the main body side walls 8, 8 on both sides of the main body bottom wall 4, and the adhesive pieces 9, 9 on both sides of the main body front wall 5 are connected to each other via a fold line. ing. Each of the inner flaps 7 is formed with a tongue piece 10 that is configured to be bent at the crease a.

On the other hand, the components of the lid 2 are such that a lid top wall 11 is connected to the main body rear wall 3 and a lid front wall 12 is connected to the lid top wall 11. Lid side walls 13 and 13 are connected to both sides of 11, and adhesive pieces 14 and 14 are connected to both sides of the lid front wall 12. Further, a cutout portion 12a for separating and exposing the cutter blade 15 at the time of use is defined by a break line b in the lid front wall 12, and the cutout portion 12a is formed on the main body front wall 5 at the time of assembling the carton. Is bonded to the bonding point 16.

A blank made of paperboard having the above structure is assembled to form a packaging web storage carton. That is, the wrap film wound around the paper tube P is housed in the carton main body 1 while being glued to necessary portions of the blank while being glued. At the time of this assembly, the tongue piece 10 formed on the inner flap 7 is arranged so as to be inside the paper tube P with a space therebetween. By folding, the tongue piece 10 stands up toward the inside of the paper tube P as shown in FIG. The wrap film to be stored is
For example, it is a synthetic resin film of vinylidene chloride, vinyl chloride, polyethylene or the like. In use, after removing the cutout 12a of the lid front wall 12 along the breaking line b, the lid 2 is opened as shown in FIG. After being pulled out by the length, it is cut by the cutter blade 15.

FIG. 3 shows a state in use.
As shown in the figure, the tongue piece 10 is in a state of rising toward the inside of the paper tube P, and holds the paper tube P so that the paper tube P does not protrude against a slight pull upward of the carton.

When the paper tube P is taken out of the carton, FIG.
As shown in (1), the tongue piece 10 is pushed down by the end of the paper tube P, and the tongue piece 10 is tilted to the opposite side. The force causes the tongue piece 10 to rise again. Then, the paper tube P is pulled out of the carton. Conversely, when returning the paper tube P to the inside of the carton, as shown in FIG.
Is folded in the original direction, but when the paper tube P is inserted to the bottom of the carton, the tongue piece 10 is located inside the paper tube P, so it rises up again due to the repulsive force at the crease a and the paper tube P pops out. To prevent

The creases a of the tongue pieces 10 are arranged obliquely with respect to the horizontal direction of the carton to exert an effect. The angle of the crease a with respect to the horizontal direction of the carton is 30 to 60 degrees,
In particular, it is preferable to set the angle close to 45 degrees. Further, it is desirable that the shape of the tongue piece 10 is generally triangular and the tip is rounded.

In the above example, the tongue piece 10 is located below the crease.
However, the tongue piece may be formed above the crease a so that the tongue piece rises in the opposite direction.

In the above embodiment, a wrap film storage carton has been described. However, the present invention is also applicable to a carton for storing other packaging webs such as aluminum foil and cooking paper. Further, as in the specific example described above, the carton may have any structure as long as it has a structure in which the inner flap 7 and the adhesive piece 9 are folded and the side wall 8 is closed by bonding the main body side wall 8. Applicable to

[0015]

As described above, the packaging web storage carton of the present invention already has the function of preventing the paper tube from popping out at the time of purchase by the consumer, so that the user has a special function as in the prior art. There is no need to take any action. In addition, since the inner flap is used to exhibit the required functions, there is no effect on the appearance or design, and the invasion of concerned dust and dirt into the carton is prevented. Further, in terms of functions, it is easy to put the paper tube in and out according to the user's will, and the function is not impaired by repetition.
