[Problems to be solved by the invention]
The packaging bag described in Patent Literature 1 has a merit that although the opening is certainly large after opening, it is easy to take out the packaged product since a broken line is formed from the grip portion to the main body portion. Due to the broken line, the gripping part is torn when taking out the packaged product, making it difficult to store cleanly after opening, or dust may enter unused roll products because the opening is too large. Further, there is a disadvantage that even the main body portion which should not be broken by mistake when opened due to the cut line of the main body portion is broken.
[0007]
The present invention has been made to solve the above-described drawbacks and problems of the conventional packaging bag, and has sufficient strength to store and transport a plurality of roll products, and to use one hand when used. Provide a packaging bag for storing roll products, which can be opened even after opening, easily retain the form of the packaging bag as it is, and store unused roll products without dust. It is.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a packaging bag of the present invention is adapted to accommodate one or more products to be packaged, a main body having a front surface, a rear surface, and both side surfaces, and front and rear surfaces of the main body portion. And a grip portion formed on the upper side of the main body portion by being overlapped. In at least one side surface of the main body, a perforation is formed so that an opening for taking out the product is formed in a region located above the position corresponding to the uppermost part of the product stored in the main body and below the grip portion. Is provided.
[0009]
Further, in another embodiment of the present invention, a packaging bag of the present invention is adapted to accommodate one or more products, a body having a front surface, a rear surface, and both side surfaces, and a front and rear surface of the body portion. And a grip portion formed on the upper side of the main body portion by being overlapped with the main body portion. At least one side surface of the main body portion has a predetermined distance below the uppermost portion of the product stored in the main body portion. A perforation is provided so that an opening for taking out a product is formed in a region located above the position corresponding to the side and below the grip portion.
[0010]
The shape of the opening formed by cutting the perforation formed on the side surface of the main body is such that one of the stored products can be taken out, and the lower end of the opening is connected to the side surface of the main body. Has been done. The overall shape of the opening is preferably bell-shaped, but more preferably the top of the opening is slightly protruding. The protrusion makes it easy to create a trigger for cutting the perforation at the time of opening, thereby facilitating the opening.
[0011]
The width of the lower end of the opening is preferably substantially equal to the distance between the centers of adjacent products stored in the main body, and having such a length prevents the product from being excessively widened for taking out the product. It is easy to maintain the form as a bag afterwards.

BEST MODE FOR CARRYING OUT THE INVENTION
Preferred embodiments of the present invention will be described below with reference to the drawings. In the following description, the same reference numerals are used for the same components throughout the drawings.
[0015]
Referring to FIG. 1 and FIG. 2, FIG. 1 is a perspective view showing a packaging bag 1 for storing a roll product of the present invention in a state in which 12 roll products are stored, and FIG. FIG. 2 is a front view of the packaging bag 1 with the gusset side surface 12 of the packaging bag 1 folded. The packaging bag 1 is formed from a general plastic film or sheet such as polyethylene, and has a main body 2 that accommodates a plurality of toilet paper rolls 10 and the like. The main body 2 has a front surface, a rear surface, and both side surfaces for connecting the front and rear surfaces. On the upper side of the main body 2, a grip portion 3 is formed by overlapping the front and rear plastic films of the main body. A seal portion 13 extending in the width direction of the main body 2 joined by heat sealing or the like is formed in a region serving as a boundary between the grip portion 3 and the main body 2. The upper edge of the packaging bag 1 serving as the upper edge of the grip portion 3 is sealed by heat sealing or the like, and a seal portion 5 is formed. In the present invention, the sealing method of the sealing portion is not limited to the heat sealing method, and an adhesive or the like may be used, or other various sealing methods can be applied.
[0016]
The bottom 9 of the main body 2 is open so that a roll product such as toilet paper can be stored therein. The toilet paper roll 10 is accommodated from the bottom 9 in the open state, and after being stored, the bottom 9 is sealed and closed by heat sealing or the like.
[0017]
As shown in FIGS. 1 and 2, two grip holes 4 are provided at predetermined positions in the grip portion 3. The finger hook hole 4 may be formed at a predetermined distance from the upper edge 5 of the grip portion 3 at a predetermined distance from the center of the grip portion 3 in the lateral direction, that is, in the width direction. A finger can be hooked when carrying the stored bag 1. If the finger holes 4 are too far from the center in the width direction of the grip portion 3, it becomes difficult to catch the fingers. In this embodiment, the finger hole 4 has a substantially circular shape, and includes an upper edge 4a in a state of being connected to the grip portion 3 and a lower edge 4b formed with a cutout line. When a finger is inserted into the finger hole 4 having such a configuration, the upper edge portion 4a is not cut off from the grip portion and remains connected, but the lower edge portion 4b can be easily torn by inserting the finger. ing. The size of the finger hole 4 may be such that the index finger or the like of an adult can be easily inserted so that the packaging bag 1 can be carried, and the shape is almost circular as in this embodiment. Alternatively, the shape can be selected from various shapes such as an oval shape and an oval shape.
[0018]
Further, a vertical seal portion 6 is formed slightly away from each of the finger holes 4 in the widthwise outward direction. Dashed lines 7 are folding ends formed by folding both side surfaces 12 of the packaging bag 1, that is, the gusset side surfaces. Each of the folded ends 7 is positioned so as to sandwich a substantially central region in the width direction of the packaging bag 1. The grip portion 3 is formed by laminating the front and rear plastic films of the packaging bag 1 as described with reference to FIG. 1, but a reinforcing material is incorporated between these plastic films so that the grip portion 3 is strengthened. It may be. The reinforcing material may be incorporated over the entire gripping portion 3 or may be incorporated only in a portion centered on the central region of the gripping portion, for example, between the vertical seals 6.
[0019]
Referring to the packaging bag 1 of the present invention shown in FIG. 1A, a perforation 8 is formed above the gusset portion of the gusset portion of the side surface 12 of the main body 2, that is, above the folded portion of the side surface 12. As shown in FIG. 1A, the shape of the perforation 8 may be a bell-like shape or a shape obtained by turning a bowl upside down. The upper side of the perforation 8 has a slightly protruding portion so that it can be opened with one hand at the time of opening. The perforation 8 draws an arc and a semicircle from the predetermined position 8a of the side surface 12 of the main body 2 corresponding to the uppermost portion when the roll product, that is, the packaged product 10 is stored, toward the side surface 12 upward. Finally, the product is formed so as to end at a predetermined position 8b of the side surface 12 corresponding to the uppermost portion of the packaged product 10 and have a bell shape. The perforation 8 is formed only on the upper side of the side surface 12, and the portion between 8a and 8b remains connected to the side surface of the main body. In other words, by cutting out the perforations 8, a bell-shaped opening 14 having the width of the connection area is formed in a state where the space between 8a and 8b is connected to the main body 2, and is stored when used. The roll product is taken out from the opening 14. Here, the distance between 8a and 8b is the width W1 of the lower end of the opening 14.
[0020]
Next, with reference to FIGS. 3A and 3B, the relationship between the opening 14 and the rolled product 10 to be packaged stored in the main body will be described in more detail. FIG. 3A is a plan view of the packaging bag 1 when two roll products 10 are stored in the main body 2 both vertically and horizontally, and FIG. 3B is a plan view of the packaging bag 1 corresponding to the plan view of FIG. It is an upper side view. In this embodiment, as shown in FIG. 3B, the width W1 of the opening 14 is substantially equal to the distance between the roll products 10 in FIG. 3A, that is, the distance between the centers of the cores 11 of the adjacent roll products 10. Preferably, they are equal.
[0021]
In this embodiment, the perforations 8 are formed only on one side surface of the main body 2, but may be formed symmetrically on both side surfaces. It is considered that the case where the packaged articles are formed on both side surfaces makes it easier to take out the packaged articles stored in a plurality of rows. Further, the shape of the perforation 8 is not limited to the bell shape as in this embodiment, and if the opening width W1 is set to be substantially equal to the interval between adjacent articles to be packed, the perforation 8 can be stored in the packaging bag 1. Various shapes are possible depending on the product to be manufactured.
[0022]
FIG. 1 (b) shows another embodiment of the present invention. In the second embodiment, the starting point 8a of the perforation 8 is a predetermined position on the side surface slightly lower than the uppermost part of the packaged product stored in the main body 2, and the end point 8b is also the packaged product. The other configuration is the same as that of the first embodiment except that the position corresponding to slightly lower than the uppermost end of the product is a position symmetrical to the left and right with 8a. The width W1 of the lower end of the opening 14 is the same as in the first embodiment, but the size of the entire opening 14 is such that the perforations 8 are longer in the vertical direction than in the first embodiment. Somewhat larger. If the distance from the side of the bag corresponding to the uppermost part of the article to be packaged in the packaging bag to 8a, 8b is too long, it is difficult to maintain the shape of the bag after opening, so unless an appropriate length is selected. No.
[0023]
FIG. 3C is a plan view of the packaging bag 1 when two roll products 10 are stored in the main body 2 both vertically and horizontally, as in FIG. 3A, and FIG. It is a side view on the upper side of the corresponding packaging bag 1. As can be seen from FIG. 3D, the interval W1 between the start point 8a and the end point 8b of the perforation 8, that is, the width of the lower end of the opening 14 is substantially equal to the interval between the adjacent roll products 10. In the case of the present embodiment, a predetermined passing point where a tapered perforation is formed from 8a upward to 8b, that is, between points 8c and 8d intersecting the position of the side surface corresponding to the uppermost end of the packaged article Is slightly smaller than the interval between the adjacent roll products 10. With such a configuration, the opening 14 obtained by the second embodiment is slightly longer than the opening of the first embodiment, so that it is easier to take. Also, as in the first embodiment, it is preferable that the uppermost portion of the perforation 8 has a protruding shape so that it can be easily opened with one hand when opening.
[0024]
Furthermore, also in this embodiment, the perforations 8 are formed on only one side surface 12 of the main body 2, but may be formed on both side surfaces. It is considered that the case where the articles to be packaged are stored in a plurality of rows is easier to be taken out when formed on both side surfaces. Further, the shape of the perforations 8 is not limited to the bell shape of the present embodiment, and if the opening width W2 is set to be substantially equal to the interval between the articles to be packaged, various shapes may be used depending on the products stored in the packaging bag 1. Can be shaped.
[0025]
Although the packaging bag of the present invention is intended to be used for sanitary thin paper such as general toilet paper and paper towel, a compact packaging method has been adopted in recent roll paper products and the like. That is, it is a method of compressing and compressing a packaged article that can be compressed during packaging. Such an example is illustrated in FIG. FIG. 4 shows a state in which the roll product 10 is deformed together with the core 11 according to the compressive stress applied to the roll product 10 during packaging. The roll 10 indicated by a broken line represents a state before a compressive stress is applied. At the time of packaging, a pressure is applied to the roll 10, and in this case, the compressive stress applied to the product 10 from the side direction of the packaging bag 1, that is, the gusset direction, is strong. weak. The state of the roll 10 when such a stress is applied is represented by a solid line. As can be seen from this figure, the portion of the roll 10 corresponding to the wrapping bag gusset side, that is, the side surface side is greatly deformed, whereas the portion of the roll 10 corresponding to the front and rear sides of the packaging bag is relatively small deformed. The plan view of the roll 10 after the application of the compressive stress is generally elliptical. In consideration of the direction and size of compression of the roll product 10 when compactly packaged in this way, as in the present invention, when the packaging bag 1 in which the product is stored is hung, it is hard to apply stress to the side of the gusset. Forming the opening is beneficial.
[0026]
FIG. 5 is a perspective view illustrating a state when the packaging bag 1 is opened. FIG. 5 shows the opened state of the packaging bag in the first embodiment of the present invention in which the perforations 8 are provided only on the upper part of the side surface 12 of the main body. At the time of opening, the opening 14 is formed with one hand cut out from the protruding portion of the bell-shaped perforation 8 while the lower end is still connected to the main body 2. The roll product 10 is taken out from the opening 14. As described above, in the packaging bag 1 of the present invention, since the opening position at the time of opening is formed only on the upper side of the side surface of the main body, the shape of the bag can be maintained almost completely after opening. Also, since the maximum opening width of the opening 14 is substantially equal to the distance between the articles to be packaged, there is no problem in taking out the article, and in addition, the article 10 to be taken out next protrudes from the main body 2. Nothing like that. Therefore, even after being opened, the packaging bag 1 of the present invention retains the shape of the bag, has a smaller opening portion because there are fewer cut-out portions as compared with the conventional packaging bag, and dust or the like enters even in the storage state. Less. In addition, the packaging bag 1 of the present invention can be carried with the packaged articles stored therein even after opening.
[0027]
In the packaging bag 1 of the present invention, since the opening at the time of opening is formed only on the upper side surface of the main body with a small load when the gripping portion is suspended and hung, it does not accidentally break even when being carried. . In addition, in the conventional packaging bag, it was necessary to tear the grip portion with both hands, but since the packaging bag 1 of the present invention does not need to tear the grip portion, it can be opened with one hand. Further, since the opening of the opening is set not to be too large, there is a great advantage that the shape of the bag can be stored in a clean appearance while maintaining the shape of the bag after opening. In addition, since the opening is small, there is an advantage that dust is less likely to enter unused packaged articles and the like.
[0028]
In the embodiment of the present invention, the number of products stored in the packaging bag of the present invention is plural, but may be a single product, and the product is not limited to a roll product. Further, everything including the material of the packaging bag, the shape of the opening, and the like is not limited to the description of the present embodiment, and can be replaced with various materials and shapes.
