TECHNICAL FIELD The present invention relates to a packaging container,
In particular, the opening cutout portion connected to at least a part of the lid portion so as to be cuttable is adhered to the adhered portion, and the packaging container closed is cut off from the lid portion. The present invention also relates to a packaging container configured to be opened by being peeled off from an adherend.

[0002]

2. Description of the Related Art Conventionally, an opening cutout portion is continuously provided through a cutout line on at least a part of the open end of the lid portion of a paper packaging container having a container body and a lid portion. A lid-side adhesive portion partially formed in the opening cutout portion along the open end side and a portion facing the adhesive portion at the time of molding are bonded with an adhesive to form a closed state, and used. In the meantime, by gripping one end portion of the opening cutout portion and pulling it toward the other end portion, the opening cutout portion is cut off from the lid portion along the cutout line, and is peeled off from the container body to be opened. Packaging containers are used.

FIG. 5 is a perspective view showing an embodiment of a conventional packaging container before being opened. This packaging container stores a thin film wound around a cylindrical core, and has a lid closed. Is made of cardboard having a substantially rectangular parallelepiped shape.

The container body 1 and the lid 2 of the conventional packaging container are formed by bending a blank made of a single piece of thick paper along a folding line (not shown) and bonding necessary portions.

[0005] The container body 1 for accommodating the wound thin film is connected to the rectangular bottom wall and both sides extending in the longitudinal direction thereof.
And a side wall 3 erected at an angle of 90 °, and end walls 4 connected to both side edges of the bottom wall and erected at an angle of about 90 ° with respect to the bottom wall.

The lid 2 has a lid upper wall 5 having the same shape as the bottom wall, and one side of the lid upper wall 5 in the longitudinal direction is formed of the container body 1 of the packaging container. The side 6 is connected to one side, and the side 6 is mountain-folded or valley-folded to cover or open the lid 2 with respect to the opening of the container body 1. It is configured to be able to.

A lid end wall 7 is provided at both ends of the lid upper wall 5 so as to extend vertically toward the container body 1 at an angle of about 90 ° with respect to the upper wall. The packaging container is configured so as to be arranged in parallel with a part of the outside of the end wall 4 of the container body 1 in a state where the lid 2 is closed.

On the other side of the lid upper wall 5, a lid side wall 8, which is perpendicular to the container body at an angle of about 90 ° with respect to the upper wall, is continuously provided. With the lid 2 of the container closed, the container is configured to be arranged in parallel outside a part of a side wall 3 (front side in the figure) which is the front of the container body 1.

Further, on the open side of the lid side wall 8,
An opening cutout 9 is formed through a cutout line 10.

The perforated line 10 has a perforated line 11 formed in advance to facilitate removal of the perforated cutout 9 and the perforated cutout 9 connected to the lid. Connecting portions 12 are alternately and continuously formed. The cut line 11 and the connecting portion 12 have a fixed size.

In the longitudinal direction of the opening cutout 9,
The bonding portion 13 has a plurality of portions (4 in the conventional example shown in FIG.
Places), and are formed at substantially equal intervals. Specifically, the bonding portion 1 located at both ends of the plurality of bonding portions
3 are respectively formed slightly inward from both ends in the longitudinal direction of the opening cutout 9, and the remaining adhesive portions 13 are formed so as to divide the adhesive portions located at both ends into substantially equal dimensions. ing. Each of the connecting portions 13 is formed with a substantially U-shaped notch 14 which is closed in the peeling direction at the time of opening, and the peeling force is applied to the tip of the U-shaped cut portion 14 (the end in the peeling direction). Section).

The bonding portion 13 is bonded with an adhesive to the front side wall 3 of the container body 1 which faces when the lid is closed. The container for packaging is closed with the opening of the container body 1 covered with the lid 2.

[0013]

The packaging container having the above-described structure is configured such that one end portion (right end in FIG. 5) of the opening cutout portion 9 is gripped and pulled toward the other end portion. Opening cutout section 9 is cut with cutting line 10
With this, it is cut off from the lid 2 and peeled off from the container body 1 to be opened.

At this time, in the conventional packaging container, the force of the user to peel off and the peeling force of the connecting portion 12 of the perforated line 10 and the bonding portion 13 of the opening perforated portion 9 are resisted. This is called so-called surface peeling in which the opening cutout 9 made of paper peels off only the upper layer portion of the cardboard material formed in a sheet shape and leaves the lower layer portion in the bonding portion. In some cases, the state may be broken off on the way. When such surface layer peeling occurs, the user further tears off the end of the opening cutout portion 9 remaining in the container body 1 with a nail or the like to form a slight grip portion. It is required to take measures such as gripping a small grip portion and trying to peel it off again, and the feeling of use has been extremely poor.

Further, in the case of a packaging container in which a thin film is wound and stored as in the conventional example, an arbitrary amount of the film may be provided on the back surface of the lid 2 where the cutout line 10 is formed in accordance with the usage amount. There is a case where a saw blade member for cutting at a length is provided, and as described above, a finger is injured by the saw blade member while the remaining portion of the opening cutout 9 where the surface layer has peeled off is peeled off. There was also danger.

If the adhesive portion 13 is formed small or the adhesive force of the adhesive is weakened, the resistance at the time of peeling will be weak, but somehow during the distribution process as a product. It is also conceivable that the adhesion of the lid portion 2 to the container body 1 is released, which is not preferable because there is a possibility that the product becomes a defective product.

Furthermore, if a packaging container is to be manufactured using a material that is unlikely to cause surface peeling, there is a problem that the cost increases.

As a result of study by the inventor on these problems, the surface layer peeling is caused when the connecting portion 12 of the cutting line 10 and the peeling end of the bonding portion 13 of the opening cutting portion 9 are at the same level. It became clear that it occurred frequently.

The present invention has been made in view of the above points, and has as its object to provide a packaging container capable of preventing surface layer peeling at the time of removing the opening cutout portion.

[0020]

In order to achieve the above-mentioned object, a packaging container according to the present invention comprises a cut line and a connecting portion at least at a part of an open end of one wall surface constituting a lid portion. The opening cutout portion is continuously provided via a cutout line, and a plurality of adhesive portions formed at intervals in the opening cutout portion along the open end face are opposed to the adhesive portion when the lid is closed. Attach it to the part with an adhesive to make it in a closed state, and in use, hold the one end of the opening cutout and pull it toward the other end, so that the opening cutout is cut along the cutout line with the lid. In a paper packaging container configured to be cut off from the bonded portion and peeled off from the bonded portion, each of the plurality of bonded portions has a peeling direction end portion directly below the peeling direction. And it is characterized in that it is formed so as to be positioned apart from the connecting portions constituting the cut line located on the side.

According to the present invention, at the time of peeling off the opening cutout portion, the connecting portion constituting the cutout line and the end portion in the most pulling direction of the bonding portion do not always have the same position. The power to peel off is
It is provided either for cutting the connecting portion of the cut line or for peeling off the adhesive portion, so that the opening cut portion can be cut off by reliably acting.

[0022]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view showing an example of the packaging container of the present embodiment before opening, and FIG. 2 is a plan view showing a state of a blank before forming the packaging container of FIG. FIG. 3 is an enlarged view showing a cut line of the packaging container of the present embodiment.

The packaging container shown in FIGS. 1 and 2 contains a thin film wound around a cylindrical core and has a substantially rectangular parallelepiped shape with the lid closed as in the conventional example. Packaging container.

The container body 1 and the lid 2 of the packaging container of the present embodiment are formed by bending a blank made of a single piece of cardboard shown in FIG. 2 along a folding line and bonding necessary portions. .

Hereinafter, only the components different from the above-described conventional example will be described.

An opening cutout 9 having a width of about 18 mm is formed through a cutout line 10 on the open side of the lid side wall 8 of the packaging container in this embodiment.

In the present embodiment, four adhesive portions 13 having a substantially U-shaped notch 14 which is closed in the peeling direction are formed in the longitudinal direction of the opening cutout portion 9. Specifically, the bonding portions 13 to be located at both ends of the four bonding portions 13 are respectively formed slightly inward from both ends in the longitudinal direction of the cutout portion 9 for opening, and the bonding portions located at both ends thereof are formed. The remaining two bonding portions 13 are formed so as to divide the portions 13, 13 into substantially equal dimensions. Note that the side bonding portions 13 of the present embodiment are each formed to have a length of about 20 mm and a width of about 10 mm.

Each of the adhesive portions 13 is formed such that its end in the peeling direction is separated from the connecting portion 12 constituting the perforated line 10 located immediately downstream in the peeling direction. ing. Note that if the dimensional distance between the end of the bonding portion 13 in the peeling direction and the end of the connecting portion 12 located immediately downstream in the peeling direction is too long, the portion is opened at the time of assembly and molding. ,
In this embodiment, the dimensional distance is set to 10 mm, which is the most preferable.

The perforated line 10 is formed by connecting the perforated line 11 formed in advance in order to facilitate removal of the perforated opening 9 and the perforated opening 9 to the lid 2. And the connecting portions 12 are alternately and continuously formed.

The connecting portion 12 constituting the cut line 10
Has a fixed dimension (about 2 mm in the present embodiment) as shown in FIGS. 1, 2 and 3, but the cut line 11 has a relationship with the position of the bonding portion 13. They are formed with different forming dimensions.

That is, as shown in FIG. 3, each of the cut lines 11 constituting the cut line 10 formed in the packaging container of the present embodiment is orthogonal to the peeling direction of the opening cut portion 9. Vertical line 11 formed as follows
A, and a horizontal line 11B formed so as to extend in the peeling direction from the longitudinal central portion of the vertical line 11A.
And a short guide line 1 that is inclined at the end of the horizontal line 11B in the peeling direction on the side opposite to the side where the opening cutout 9 is provided.
1C.
3. The horizontal line 11B adjacent to the end in the peeling direction 3
Are formed longer than the formation dimensions of the other horizontal line 11B. More specifically, in the present embodiment, the other horizontal line is formed at 9 mm, whereas the horizontal line adjacent to the peeling direction end of the bonding portion 13 is formed at 18 mm.

In this embodiment, the cover 2
On the back side of the connecting position of the opening cutout 9 at the time of opening,
A saw blade member (not shown) that protrudes along the open end where the opening cutout 9 of the lid 2 is formed is provided.

By forming the vertical line 11A, the variation in the tear direction when the opening cutout 9 is torn off from the lid 2 by the connecting portion 12 of the cutout line 10 can be determined by forming the vertical line 11A. The guide line 11C allows the opening cutout portion 9 to be connected to the cover portion 2 by the connecting portion 12 of the cutout line 10.
The purpose of this is to prevent the direction of the tear when the sheet is torn from the opening 2 toward the open end side of the lid 2. By doing so, it is possible to prevent the exposure of the saw blade of the saw blade member from being hindered by, for example, the edge of the lid side wall 8 remaining after the opening cut portion 9 has been cut.

The shape of the cut line 11 is not limited to the above-described configuration. For example, the vertical line 11A, the guide line 1
1C does not have to be formed, and it is not necessary that all cut lines other than the horizontal line 11B adjacent to the end of the adhesive portion 13 in the peeling direction have the same length. The length of the horizontal line 11B may be adjusted.

According to the packaging container of the present embodiment configured as described above, the connecting portion 12 forming the cutout line 10 and the bonding portion 13 of the opening cutout portion 9 when the opening cutout portion 9 is peeled off. Since the end portions in the pulling direction are not at the same position, the force for peeling off the opening cutout portion 9 always depends on whether the connecting portion 12 of the cutout line 10 is cut off or the adhesive portion 13 is peeled off. Thus, the opening cutout portion 9 can be cut out reliably.

Further, the packaging container of the present embodiment can be manufactured simply and at low cost by bending one blank along a folding line and bonding necessary portions. By disposing a saw blade member on the back side of the connecting position of the opening cutout portion 9 of the lid 2, the wound long content such as a wrap member is pulled out to a required length, and the lid 2 is pulled out. Can be easily cut with the saw blade member disposed on the end side of, so that a better feeling of use can be obtained.

In the present embodiment, the lid 2 having the side wall 8 has been described. For example, as shown in FIG. 4, the lid 2 is taken out to the upper end sides of both side walls 22 and both end walls 23 of the container body 21. The ears 24 are continuously provided, and each of the taken-out ears is bent inward and overlapped, so that the taken-out ears 24 superimposed on the uppermost layer function as the lid 25. An adhesive portion is formed on the take-out ear portion (usually a take-out ear portion disposed at a position facing the take-out ear portion serving as a lid portion) formed on the cutout line 27 and superimposed on the second layer from above 2
The present invention is also applicable to a case where the closed state is made by bonding 8.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified as needed.

For example, the size of the cut line can be changed according to the size of the packaging container.

[0041]

As described above, the packaging container according to the present invention can prevent so-called peeling of the surface layer at the time of cutting off the opening cutout portion at the time of opening, so that the usability is good. In addition, even if the saw blade member for cutting the contents at an appropriate length from the side of the lid is exposed after cutting the opening cutout portion, the opening cutout portion can be cut smoothly. If the user, as a result of surface peeling,
It is safe because the finger is not injured when removing the opening cutout remaining in the container body.

Further, since it is not necessary to weaken the adhesive strength between the container body and the lid, the adhesion of the lid to the container body is released, and the product itself can be distributed with the lid opened. This has the effect of preventing and reducing the amount of defective products.
