However, in such a conventional packaging paper container made of corrugated cardboard or the like, if the lid on the upper surface is opened with a cutter or the like, the stored items may be damaged or If you do not use all the items stored in, the lid on the upper surface may be folded again, but unless you seal it again with adhesive tape, you cannot completely seal the upper surface and the stored items There was a problem that the management of was insufficient.

On the other hand, a packaging paper container made of corrugated cardboard or the like in which a cutting tape is arranged on the upper surface or around the body can be easily opened unlike the case where the adhesive tape or the like is peeled off. However, once opened, no consideration was given to the mutual restraint between the upper side and the lower side of the paper container separated by the cut tape. It was difficult to secure and, in addition, was difficult to reseal. Further, when the thickness of the paper in the packaging paper container becomes thick, there is a problem that opening with a cut tape is not easy.

Further, in a packaging paper container made of cardboard or the like, in which the separate lid and the paper container body are separately manufactured, it is not easy to manufacture so that the separate lid and the paper container body are in close contact with each other. In addition, when the adhesive tape or the like that secures the separate lid and the paper container body is peeled off, there is a problem that it cannot be easily peeled off depending on the material of the paper container. The present invention aims to solve such problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A packaging paper container according to the present invention will be described in detail with reference to the drawings. 1 is a view showing a released state of a packaging paper container according to the present invention, FIG. 2 is a diagram showing a closed state of a packaging paper container according to the present invention, and FIGS. 3 to 5 are diagrams showing a packaging paper according to the present invention. FIG. 11 is a view after the container is cut off with a cut tape, and FIGS. 6 to 10 are developed views of the inner frame according to the present invention.

As is apparent from these figures, in FIGS. 1 and 2, reference numeral 1 is a paper container, and among three surfaces around the body of the paper container 1, three surfaces or four surfaces are provided. The cut tape 4 is arranged on the inner surface of the. Inside the paper container 1, an inner frame 2 is closely attached to a position higher than the cut tape 4 and equal to or lower than the uppermost surface of the paper container 1. The inner frame 2 is shown in FIG.
As shown in FIGS. 5 to 5, when the paper container lid portion 1a and the paper container body portion 1b are integrally formed by the connecting portion 1c by peeling the cut tape 4 over the three surfaces, the inner frame 2 Since the upper part of the above appears above the paper container body 1b, the inner frame 2 restrains the paper container lid 1a and the paper container body 1b from being displaced.

On the surface on which the cut tape 4 is arranged, two perforations having the same width as the cut tape 4 and having two upper and lower tiers are placed on the three surfaces excluding the connecting portion 1c. 4 is easy to peel off. However, it is not always necessary depending on the thickness of the paper in the paper container 1. At that time, as shown in FIGS. 1 and 2, the opening 7 is provided at the end portions of the three surfaces on which the cut tape 4 is to be peeled off.
If the cut tape 4 is provided in two places, the cut tape 4 can be easily peeled off. In this case, the position of the opening 7 is set to the cut tape 4
May be provided in the center of the middle surface of the three surfaces from which the peeling is to be performed. In any of the above cases, the opening 7 may be provided at two locations or one location. Furthermore, in the connecting portion 1c,
If one of the upper and lower rows of the perforations inserted along the cut tape 4 is extended, it functions as a hinge and is easy to use.

The inner frame 2 can be of various types, as shown in FIGS. 6 to 8 correspond to the inner frame 2 shown in FIG. 3, and in FIGS. 6 and 8, the adhesive member 2a is formed at the end portion to form a tubular shape in advance. After that, it is inserted into the paper container 1, and among them, FIG. 8 is provided with a lower surface 2b so that a heavy object can be stored therein, and FIG. 7 shows a cylindrical shape by being arranged inside the paper container 1. To be formed.

Further, the one shown in FIG. 9 corresponds to the inner frame 2 shown in FIG. 4, and the paper container lid portion 1 has only three surfaces.
I am trying to restrain a. In this embodiment, two of the three surfaces of the inner frame 2 are formed to have a width that is about half the width of the paper container 1, but even if the width is greater than half, the surface of the paper container 1 may be different. Can be as wide as In addition, even if the width is smaller than half the surface of the paper container 1, the inner frame 2 may be 1
It may be only one side. When the inner frame 2 has only one surface, the width of the inner frame 2 may be the same width as the surface of the paper container 1 or may be smaller.

In addition to this, as an embodiment, as shown in FIG. 10, there is a case corresponding to the inner frame 2 shown in FIG. 5 need not be limited to the two corners opposite to the connecting portion 1c as shown in FIG. 5, or may be arranged at the three corners or the four corners, or only one corner in some cases. In addition, the pillars placed in each corner are individually and independently
It is advisable to stick the inside of the paper container 1 below the portion where the cut tape 4 is arranged with an adhesive or the like.

On the other hand, an opening 6 is provided on the upper surface of the paper container 1. This opening portion 6 is used when storing an item in the paper container 1. However, the opening 6 is not limited to one that opens in four directions as shown in FIG. 1, and may open in one direction or two directions. Further, after the articles are stored, they can be sealed by a sealing means such as the adhesive tape 5. Further, the opening 6 is not limited to the upper surface, and may be provided on the lower surface or at another place.

The paper used for the paper container 1 and the inner frame 2 is usually cardboard, but a combination of cardboard and other paper may be used, or only other paper may be used. The thickness of the paper used for the paper container 1 and the thickness of the paper used for the inner frame 2 are usually the same, but different thickness combinations may be used. However, there is an advantage that it is easier to pull the cut tape 4 when the paper container 1 is thinner.

The packaging paper container according to the present invention is constructed as described above, and its operation will be described below. In the packaging paper container according to the present invention, first, the paper container 1 is assembled while the opening 6 is open. Similarly,
After assembling the inner frame 2, the inner frame 2 is inserted into the paper container 1 to complete the assembly. Next, a product is stored through the opening 6 shown in FIG. 1, the opening 6 is folded, and then the opening 6 is sealed by a sealing means such as an adhesive tape 5. In a sealed state, this packaging paper container is stored / transported ...

Next, when the stored items are to be taken out, the opening 7 of the cut tape 4 disposed on three or four of the four surfaces around the body of the paper container 1 From top to bottom with approximately the same width as the cut tape 4
The paper container lid portion 1a and the paper container main body portion 1b are integrally formed at the connecting portion 1c by peeling off the paper container over the three surfaces along the perforations arranged in steps. At that time, since the paper container lid portion 1a is constrained by the inner frame 2 configured to be in close contact with the inside of the paper container body portion 1b, the paper container lid portion 1a and the paper container body portion 1b are displaced from each other. There is no such thing. Further, the connecting portion 1c serves as a hinge.

[0018]

As is apparent from the above description, the packaging paper container according to the present invention can obtain the following effects. By peeling off the cut tape of the paper container of the packaging paper container and forming the paper container lid part and the paper container body part as one body at the connecting part, the lid can be formed extremely easily Since no tape is used, it is easy to open and does not damage the contents. In particular, the connecting part plays the role of a hinge, and at the same time, since the paper container lid and the paper container body are integrated at the connecting part, the paper container lid is separated from the paper container body and becomes missing. There is no worry about becoming.

Further, since the paper container lid portion and the paper container main body portion can be integrally manufactured, the manufacturing cost is low and the degree of adhesion when the lid is covered is high. Further, by disposing the opening and the perforations in the cut tape portion, the cut tape can be easily peeled off. Further, the inner frame can be inserted from the upper opening after assembling the paper container, and it does not take time and effort. Moreover, if the thickness of the inner frame is made thicker than the paper container, the pulling force of the cut tape may be small, but the thick inner frame makes it a sturdy paper container, especially with the lower surface. If you do, you can put heavy things in.
