Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a package with a cut portion.
[0002]
[Prior art]
As is well known, there are a wide variety of packaging forms such as pillow packaging, four-side seal packaging (three-side seal packaging), and deep-drawn packaging, but basically one or more packaging sheet materials. Is used to surround the packaged object and to seal by sealing a predetermined portion that has been polymerized.
[0003]
As an example, as shown in FIG. 1, the film polymerization ends at the periphery of the two packaging sheet materials 1 are sealed to produce a seal portion 2, and a package 3 sealed by the seal portion 2 is formed.
[0004]
Examples of the packaging sheet material 1 include various resin films, paper sheets (including laminating processing), and the like, and there is a packaging sheet material 1 that is easy to tear, and some that are difficult to tear. In addition, there are certain directions that are easy to tear. Therefore, when the cut portion 4 is formed at a predetermined position on the outer peripheral edge of the seal portion 2 and the package is opened, the cut portion 4 is held by having the seal portion 2 around the cut portion 4 and pulling in a predetermined direction. The packaging sheet material 1 is torn from the insert 4.
[0005]
And the shape of the notch | incision part 4 is devised so that the said direction to be cut may become a desired direction. As an example, there is a so-called V-notch cut out in a triangular shape as shown. In addition to such a shape, for example, as shown in FIG. 2A, one linear notch 4 ′ (referred to as an I notch) extending inward from the peripheral edge, or FIG. ) And the like, a cut portion 4 ″ having a shape cut into a pentagon is also provided.
[0006]
[Problems to be solved by the invention]
For example, in the case of the cut portion 4 ′ (I notch) shown in FIG. 1A, since it is one line, it is difficult for the user to find the position of the cut portion 4 ′, and the opening operation is not performed. There is a problem that it is difficult.
[0007]
On the other hand, in the case of the cut portion 4 (V notch) shown in FIG. 1 or the cut portion 4 ″ shown in FIG. 2B, the seal portion is conspicuous compared with the cut portion 4 ′ (I notch). Since the side edge of 2 is cut into a predetermined shape, it not only looks bad, but also punches out the corresponding part at the time of manufacture. Therefore, a further mechanism for collecting such garbage is required.
[0008]
The present invention has been made in view of the above-described background. The object of the present invention is to make it easy to confirm the position of the cut portion, to easily open the container, and to reduce the amount of dust generated during manufacturing as much as possible. An object of the present invention is to provide a package with a notch that can be suppressed.
[0009]
[Means for Solving the Problems]
In order to achieve the above-described object, the package with a cut portion according to the present invention surrounds an item to be packaged with a packaging sheet material, seals the overlapping end of the packaging sheet material, and determines a predetermined seal portion of the sealed portion. Assume a package with an opening for opening at a position. And the said notch part consists of the area | region enclosed by one notch line in which one end reaches the outer edge of a package and the other end is located near the said outer edge in a seal | sticker part, At least a part of the line is located closer to the center of the package than the other end , and the package sheet is cut from the portion located on the center toward the center of the package. It was configured to be opened .
[0010]
Further, on the same premise as described above, the cut portion is surrounded by one cut line whose one end reaches the outer edge of the package and the other end is located near the outer edge in the seal portion . consist region, the score line is at least one organic direction converted sites package is opened the packaging sheet material from that direction converted site is torn up toward the center side of the packaging can also child as.
[0011]
The direction-converted portion can be a bent portion or a curved shape (a circular or elliptical arc or an arbitrary curved surface). In addition, a bending part can be made into V shape, for example.
[0012]
According to this invention, since the other end of the cut line is located in the seal portion, the region surrounded by the cut line is not removed and is connected to the package. Therefore, since the area that has been removed at the time of manufacturing is still integrated with the packaging body, the removed portion (chip) is scattered as trash around the packaging machine, and to prevent such a scatter. It is no longer necessary to provide a device for collecting the removed chips (dust). Furthermore, since at least a part of the cut line is positioned closer to the center of the package than the other end of the cut line, or the direction is changed at an appropriate position of the cut line, Is present on the secondary plane, unlike the conventional I notch, the position of presence is conspicuous, the position of the cut portion (opening position) is easy to find, and the opening can be performed easily.
[0013]
Moreover, in each above-mentioned invention, it is good to make it the outer edge of the area | region enclosed by the said cut line located on the extension line of the outer edge of the said adjacent package. If it does in this way, the outer periphery of a package will not enter inside in the part of a notch part, and an appearance will be beautiful.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 3 shows a preferred embodiment of the package with a cut portion according to the present invention. In this Embodiment, the example applied to what is called a four-side seal package 10 is shown. As shown in the figure, the four-side sealed package 10 is formed in a sealed bag shape by heat-sealing and bonding the peripheral portions of two rectangular packaging sheet materials 11. By being heat-sealed, the four sides of the periphery become the seal portion 12. The packaging sheet material 11 may be a generally used packaging material such as paper or various synthetic resin films.
[0015]
In addition, as the articles to be packaged accommodated in the package, there are various types such as a plurality of solid materials such as baskets, granular materials, powders, and liquids. Furthermore, it may be a sheet-like material (a kind of solid material) such as a poultice, and the type of the packaged object is not limited.
[0016]
In the case of this type of package, the cut portion 13 is provided at a predetermined position of the seal portions 12 on the four sides. Usually, the upper side 10a portion of the four-side seal package 10 is often removed and opened. Therefore, the cut portion 13 is provided at a position in the vicinity of the upper side 10a side of the one side 10b of the four-side seal package 10. In the illustrated example, it is provided only on one side 10b, but it may of course be provided on both sides. Furthermore, it may be provided on the upper side 10a side and the side side 10b side may be removed and opened, and the installation position of the cut portion 13 is arbitrary.
[0017]
The shape of the cut portion 13 is formed by a single continuous cut line. That is, as shown in an enlarged view in FIG. 4, in this embodiment, it is formed by a substantially V-shaped cut line, and one end 13 a thereof reaches the outer peripheral edge of the four-side sealed package 10 (seal part 12), The other end 13b is located in the seal portion 12 so as not to reach the outer peripheral edge. Furthermore, since the cut portion 13 of this embodiment is substantially V-shaped, it is bent once at an intermediate position of the cut line, but the bent portion 13c is located on the innermost side in the seal portion 12. .
[0018]
The angle θ1 formed between the foot of the perpendicular line from the bent portion 13c toward the side 10b and the cut portion 13d connected to the one end 13a, and the cut portion 13e connected to the foot of the vertical line and the other end 13b Are equal to each other. As a result, the both incised portions 13d and 13e have a line-symmetrical relationship with the perpendicular foot as the center. Thereby, as the whole cut part 13, it will face the direction of the leg of the above-mentioned perpendicular.
[0019]
Further, as described above, the other end 13b is located in the seal portion 12, and the one end 13a reaches the outer peripheral edge. Accordingly, the triangular region R surrounded by both the cut portions 13d and 13e is connected to the four-side seal package 10 (seal part 12) on the other end 13b side, and is separated on the one end 13a side to be in a free state. It has become.
[0020]
Therefore, in the state of the unopened four-side seal package 10, the region R is also present in the seal portion 12 as it is, and therefore the outer peripheral edge of the four-side seal package 10 is a portion where the cut portion 13 exists (region R). The outer peripheral edge) substantially coincides with the outer peripheral edge of the other seal portion 12, and the side 10b is linear. That is, since there is no space part cut out like the cutting part 4 of the conventional V notch etc., it not only looks beautiful, but it does not get caught in the cutting part 13 either.
[0021]
And when opening, it grasps the predetermined position (each outer side of both cutting site | parts 13d and 13e) of the seal part 12 around the notch part 13, and seals from the bending part 13c by pulling in a predetermined direction. It is torn toward the inside of the part 12 (in the direction of the leg of the perpendicular). The region R does not affect the opening of the package, and the tearing process at the time of opening functions similarly to the V notch in this embodiment, and can be opened smoothly. Prior to the opening process, the region R may be cut off.
[0022]
Further, since the cut portion 13 is bent as a single cut line and exists on the secondary plane, it is easy to find unlike the single straight cut portion 4 'such as an I notch. Further, when the color of the region R is changed, the portion of the cut portion 13 is conspicuous, and it becomes easier to find the opening start position.
[0023]
In the above-described embodiment, the incision portion 13 is configured by a substantially V-shaped incision line. However, the present invention is not limited to this, for example, as shown in FIG. A shape in which the cut portion 13d is formed in a “letter shape” orthogonal to the side edge, or is bent at a plurality of locations as shown in FIG. 5B, and the region R ′ has a pentagonal shape. It can be. Further, as shown in FIG. 5C, the shape of the cut line may be U-shaped (J-shaped), and the inside may be a curved shape 13c ′ instead of a bent portion. Of course, the drawings are merely examples and listed, and various shapes other than those illustrated can be used.
[0024]
Moreover, the form of the applicable package is not limited to the four-side seal package, and can be applied to various other forms such as a three-side seal package, a pillow package, and a deep-drawn package.
[0025]
【Effect of the invention】
As described above, in the package with a cut portion according to the present invention, one cut line in which one end reaches the outer edge of the package and the other end is located in the seal portion is two-dimensionally arranged. Therefore, it is easy to confirm the position of the cut portion, the opening can be easily performed, and the amount of dust generated during manufacturing can be suppressed as much as possible.
