DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag for a sanitary article to be used. More particularly, the present invention relates to a packaging bag for disposable sanitary ware packaged in a compressed state.

[0002]

2. Description of the Related Art In general, a packaging bag for disposable sanitary goods is provided with a perforation line for opening. Many of the perforations extend from the upper surface of the packaging bag, or from the upper surface to the front surface, or from the upper surface to the rear surface, or from the upper surface to the front surface (rear surface) and a part of the side surface. The shape is provided so as to extend laterally downward with the shape as a tearing start point, and the takeout opening is very large. For this reason, it may be difficult to open the package along the perforations, or a large amount of hygiene articles may jump out when carrying after opening. As a countermeasure, a packaging bag with perforations on the side of the packaging bag, that is, on the side, has also been proposed.
No. 7, JP-A-3-669).
Since the pressing of the packaging bag is not performed when the product is opened, the compressed product may jump out of the packaging bag through the opening, which is not yet sufficient.

[0003] In addition, due to compression packing, vibrations, dropping, etc., occur when carrying out forklift transportation, stacking, transportation and other handling of a collection of packed products and putting them in a container such as cardboard. If the product is subjected to an impact, or if an individual product is carried, or subjected to an impact due to dropping during display or the like, the perforations may be torn and the product jumps out, or the product becomes full view and loses its commercial value.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the conventional packaging bag for disposable sanitary goods,
It is an object of the present invention to provide a disposable sanitary ware packaging bag in which the product is easily taken out when the opening perforation is opened and the product does not jump out of the packaging bag.

[0005]

Means for Solving the Problems According to the present invention, a predetermined number of folded and used sanitary articles are superposed on each other and arranged in a predetermined number to form one row, and one or more rows of the sanitary articles are arranged in parallel. In a state where the object is compressed by applying pressure to its wide surface and the package is packed, two side surfaces that are in contact with the wide surface of the sanitary ware and a narrow surface (narrow surface) of a predetermined number of sanitary products arranged in a row are formed. Side), a front surface and a rear surface that are in contact with the front surface, a surface that is continuous with the front surface and a surface that is continuous with the rear surface, and an upper surface that is a surface formed with a handle at a joint between the two surfaces, and a sanitary article In a packaging bag for disposable hygiene articles constituted by a lower surface which is a bottom surface to be sealed, the upper surface and the front surface and / or the upper surface and the rear surface are formed by perforation lines. A tear-open portion, The sealing portion is formed by a first opening portion formed at the position of the upper surface at the beginning of tearing and a cutting line parallel to the perforation having a width of 5 to 100 mm following the first opening portion. And a packaging bag for disposable hygiene articles.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. The sanitary articles used in the present invention are mainly used diapers, but also include sanitary napkins and the like. Further, a polyethylene bag is usually used as the packaging bag, but the present invention is not limited to these.

[0007] In the present invention, the packaged sanitary ware is folded and laid on a wide surface to form a predetermined number of rows, and the rows are aligned in one row, or vertically or horizontally. A plurality of the sanitary articles are arranged in parallel in the direction or in the vertical and horizontal directions at the same time. The packaging bag, in a state in which the sanitary ware is packaged, has two side surfaces that are in contact with a wide surface of the sanitary ware, a front surface and a rear surface that are in contact with a predetermined number of sanitary products arranged in the row, and a front surface and a rear surface. An upper surface, which is a surface formed with a handle at a joint between the two surfaces, and a lower surface, which is a bottom surface for storing and sealing the sanitary ware, is formed of two surfaces continuous to each of the rear surfaces. ,further,
A tear opening portion formed by a perforation line at a position of the upper surface and the front surface and / or the upper surface and the rear surface, wherein the tear opening portion is a first opening portion serving as a starting point of tearing;
And a second opening portion following the opening portion.

[0008] The first opening portion is formed on the upper surface, and is preferably provided at a position separated from the boundary line between the upper surface and the front surface or between the upper surface and the rear surface by 10 mm or more. 10 mm from the border
If it is less than this, even if the perforation at the tearing start point of the first opening portion is pressed with a finger, the packaging bag is not easily broken, and even if it is broken, the product may be hit with a finger and the product may be damaged or broken. Further, the position of the first opening portion is preferably at the center or near the center in the width direction of the upper surface, but may be provided at another position. However, it is preferable that there is no perforation for opening on the side surface. If a perforation is present on the side surface, the perforation may be weak against impact such as transportation or dropping, and the perforation may be torn and the product may jump out of the perforation. The shape of the outlet of the first opening portion is not particularly limited as long as it is easy to open, such as a rectangle, a trapezoid, a semicircle, a semiellipse, and a triangle.

The second opening following the first opening is 5-10
It is formed by parallel perforated cut lines having a width of 0 mm. If the width of the second opening is less than 5 mm, it is difficult to take out the product after opening. On the other hand, if the width is more than 100 mm, the product may jump out when carrying after opening, or may be impacted by transport, transportation, dropping, etc. The eyes may split and the product may jump out of it. The second opening portion is usually formed by two cut lines parallel to each other. However, if necessary, a parallel cut line may be further provided between the two cut lines to form the second open portion with three or more cut lines. Good.

The second opening portion is formed only on the front surface and / or the rear surface, or between the upper surface and the front surface and / or the upper surface and the rear surface. The position of the end point of the perforation of the second opening portion is preferably formed to the vicinity of the lower surface of the front surface or the rear surface for ease of taking out, but is not particularly limited.

[0011] In the present invention, the tear opening portion is a side from the upper surface to the front surface, or a side from the upper surface to the rear surface,
May be formed on either one of the sides, but if formed on both sides, either side may be opened, which is convenient for opening. Further, in the case of a packaging bag as shown in FIG. Since the perforated cut line can be processed by overlapping the front surface and the rear surface later, the processing is easy. Further, the tear-open portion may be formed perpendicular to the vertical direction of the packaging bag,
Alternatively, it may be formed obliquely, and there is no particular limitation.

The tear-open portion may have a perforation line formed continuously from the upper surface to the front surface and / or from the upper surface to the rear surface, but the boundary line between the upper surface and the front surface or between the upper surface and the rear surface. It may not be formed in a predetermined area in the vicinity and may be discontinuous. It is preferable that the perforated line is discontinuous because the perforated line can maintain strength against impacts such as transportation, transportation, and dropping than those formed continuously. When the tear opening portion is formed discontinuously, the first opening portion may be formed on the upper surface, and the second opening portion may be formed on the front surface or the rear surface.
The first opening part and a part of the second opening part following the first opening part may be formed on the upper surface, and the remaining part of the second opening part may be formed on the front surface or the rear surface. In addition, the length of the above-mentioned predetermined area where no cut line is formed is 10 to 30 mm, preferably 15 to 25 mm in the direction of the cut line. When the length of the area where the cut line is not formed is less than 10 mm, the strength against impact does not change from the case where the cut line is continuously formed,
If it exceeds 30 mm, it becomes difficult to tear the packaging bag along the cut line.

There are no particular restrictions on the size and spacing of the perforations, and any size and spacing that are normally used may be used. However, since the package is a compressed package, it must have sufficient strength so that it does not break during storage.
