Description

  The present invention relates to a packaging bag that can be easily opened even by a weak consumer and is not easily broken when carried, and is suitable for packaging sanitary goods such as toilet paper and kitchen paper.

  Conventionally, when selling sanitary products such as roll-shaped toilet paper, it is common to store a plurality of items to be stored such as toilet paper in a packaging bag, and form a packaging bag for storing As a material, a plastic package film that is soft and has high strength is generally used.

  And as a storage form of toilet paper in a packaging bag having a grip handle at the top, for example, four toilets are arranged in a row and stacked in three stages to store a total of 12 toilet papers. In other cases, there are cases where two toilets are arranged in a row and stacked in three tiers, and a total of six toilet papers are stored. It was to be offered for sale.

  In other words, since a plastic package film having a high strength is used as a packaging material so as not to be inadvertently broken before and after sales, it may be difficult to open the packaging bag when using toilet paper. It comes to occur. For this reason, the appearance of the packaging bag after opening is generally not good as a result that the packaging bag must be forcibly broken and opened.

  On the other hand, a perforation is provided around the handle and the packaging bag is opened from the perforation part, or a perforation is provided at the bottom of the packaging bag and the part is opened from this part. A packaging bag in which improvement measures are taken is known.

  However, when the perforation is provided in the packaging bag, there is a defect that force is applied when carrying the toilet paper in a state in which the toilet paper is stored in the packaging bag, and the perforation breaks carelessly. On the other hand, although it may be possible to narrow the perforation cut width to prevent inadvertent breakage, in this case it becomes difficult for consumers with weak power such as elderly people to open the contents. It comes to have the disadvantage that it becomes difficult to take out the toilet paper.

  As described above, the main object of the present invention is to provide a packaging bag that can be easily opened even by a weak consumer and is not easily broken when carried.

The packaging bag according to claim 1 is a packaging bag in which a plurality of objects to be stored formed in a roll shape are stored in a form in which a plurality of outer peripheral surfaces are in contact with each other in the same plane,
The arrangement of the objects to be stored formed in a roll shape is an arrangement in which four pieces per row are arranged in three tiers, or two pieces are arranged in one row and arranged in three tiers,
In the side region covering the outer peripheral surface of the storage object, only the portion between the storage objects arranged in the same plane, the part adjacent to the top surface area covering the upper end surface of the storage object, A perforation having a length corresponding to two steps of the object to be stored is formed so as to extend linearly along the axial direction .

The operation of the packaging bag according to claim 1 will be described below.
According to the packaging bag of the present invention, a plurality of objects to be formed in a roll shape are arranged in a three-tiered manner with four per row arranged in a form in which a plurality of outer peripheral surfaces are in contact with each other in the same plane . They are stored in an arrangement or an arrangement in which two are arranged per stage and are arranged in three stages . And the perforation is formed only in the part between the to-be-contained objects arrange | positioned in the same plane in the side surface area | region of the packaging bag which covers the outer peripheral surface of a to-be-contained object.

  Therefore, according to the packaging bag according to the present claim, even when the packaging bag is lifted together with the articles to be stored from the handle portion that normally exists on the upper surface of the packaging bag, the same in the side region of the packaging bag that is difficult to apply tension. The perforation breaks carelessly from the perforation when carrying the packaging bag in which the stored items are stored by arranging the perforation between the stored items arranged in the plane. Nothing will happen.

  On the other hand, when opening the packaging bag according to this claim, it is not necessary to reduce the cut width of the perforation, so even a weak consumer such as an elderly consumer can easily open the packaging bag from the perforation. It becomes easy to take out the roll-shaped contents to be stored from the packaging bag.

Moreover, in this claim, it has the structure that the perforation was formed so that it might extend linearly along the axial direction of a to-be-contained object.

  That is, according to this claim, it is necessary to make the perforation openable by a consumer with weak force, but it extends linearly along the axial direction of the object to be stored formed in a roll shape. In addition, perforations are formed. From this, for example, the necessary perforation length can be easily ensured as compared with the case where the perforation is formed in a direction crossing the axial direction of the object to be stored.

Moreover, in this claim, it has the structure that the perforation was formed in the side surface area | region from the part adjacent to the top | upper surface area | region which covers the upper end surface of a to-be-contained object.

  That is, according to this claim, the perforation is formed in the side surface region from the portion adjacent to the top surface region of the packaging bag. From this, for example, it becomes easier to secure the perforation of a necessary length compared to the case where the perforation is formed only at the lowermost part of the side region of the packaging bag.

The operation of the packaging bag according to claim 2 will be described below.
The packaging bag according to the present invention has the same effects as the inventions of the first to third aspects. However, the present invention has a configuration in which the tie cut ratio of the perforation is set to a value in the range of 1: 4 to 1:15.

  That is, according to this claim, when the tie cut ratio of the perforation is made smaller than 1: 4, the perforation is hardly broken. On the other hand, when the tie cut ratio of the perforation is larger than 1:15, the packaging bag easily breaks from the perforation portion when the packaging bag is carried. For this reason, the range of the tie cut ratio of the perforation is defined as the above range.

  As described above, according to the packaging bag of the present invention, it is possible to produce an excellent effect that even a consumer with weak power can easily open the bag and is not easily broken when carried.

It is a perspective view which shows one Embodiment of the packaging bag which concerns on this invention. It is a front view which shows one Embodiment of the packaging bag which concerns on this invention. It is a top view which shows one Embodiment of the packaging bag which concerns on this invention. It is an enlarged view which expands and shows the perforation applied to one embodiment of the packaging bag concerning the present invention.

Hereinafter, an embodiment of a packaging bag according to the present invention is shown in FIG. 1 to FIG. 4, and the present embodiment will be described in detail with reference to these drawings.
The packaging bag 10 according to the present embodiment is composed of a packaging material in which a plastic film or sheet such as polyethylene, which is a stretched film having a thickness of 0.03 mm, is formed into a cylindrical shape. As shown in FIG. 1, this cylindrical packaging bag 10 is a gusset bag in which both side end surfaces 16, 18 are folded inward, and is completed by fusing for each length of the bag. . That is, the packaging material forming the packaging bag 10 has a front surface 12, a back surface 14, and side end surfaces 16 and 18, and creases L that are folded inward are formed on both side end surfaces 16 and 18, respectively.

  When manufacturing the packaging bag 10 in which the items to be stored are stored, when the lower side of the packaging material is welded, the side end surfaces 16 and 18 are stacked together with the lower ends of the front surface 12 and the back surface 14 and one end is sealed, A bottom portion 22 is formed. Further, at the time of welding of the upper side of the packaging material, after storing the toilet paper 30 as the storage object, the side end surfaces 16 and 18 are laminated together with the upper ends of the front surface 12 and the back surface 14 and the handle portion 24 having a required width positioned on the upper side. This handle portion 24 is sealed as a result of the formation. The handle portion 24 is formed with two hand holes 26 for punching fingers.

  On the other hand, between the bottom part 22 and the handle part 24, a main body part 10A of the packaging bag 10 having a cylindrical space inside for storing the toilet paper 30 is located, and constitutes the main body part 10A. The front surface 12, the back surface 14, and the side end surfaces 16, 18 form a side region 20 of the packaging bag 10 that covers the outer peripheral surface 30A of the toilet paper 30.

  In the present embodiment, as shown in FIGS. 1 to 3, four toilet papers 30 formed in a roll shape are arranged in contact with the outer peripheral surfaces 30 </ b> A in the same plane. In shape, four pieces are stacked in three stages and stored in the main body 10A. Further, a top surface area 28 which is a portion covering the upper end surface of the toilet paper 30 is similarly formed by the front surface 12 and the back surface 14 between the main body portion 10A and the handle portion 24 of the packaging bag 10. Yes.

  As shown in FIGS. 1 to 3, the inside of four toilet papers 30 arranged in each stage, which is a central portion of the front surface 12 in the side surface region 20 and is a roll non-contact portion C. A perforation 32 is formed only in a portion between the two toilet papers 30 on the front side. That is, in the packaging bag 10 of the present embodiment, only the roll non-contact portion C of the front surface 12 locations in the side region 20 that is a portion between the two toilet papers 30 arranged in the same plane, A perforation 32 is formed.

  The perforation 32 starts from the end of the side surface region 20 adjacent to the top surface region 28 that is the uppermost portion of the side surface region 20, and starts from this portion in the axial direction of the toilet paper 30 (Z direction in FIG. 2). The toilet paper 30 is formed to have a length S of about 228 mm, which is a length in which the toilet paper 30 is stacked in two stages. In this case, the tie cut ratio of the perforation 32 is set to a value in the range of 1: 4 to 1:15.

  That is, as shown in FIG. 4, for example, the cut length L of the perforation 32 is 5.0 mm and the interval T is 1.0 mm, so that the tie cut ratio of the perforation 32 is 1: 5. Here, the tie cut ratio is a ratio between the interval T of the perforation 32 and the cut length L of the perforation 32, and the value of L relative to T of the tie cut ratio T: L is relative. The smaller the size, the harder it is to separate, and the larger the value of L with respect to T, the easier it is to separate. That is, according to this tie-cut ratio, the smaller the L with respect to T, the higher the tensile strength (JISP8113) at the perforation 32.

  In addition, the magnitude | size of the packaging bag 10 which concerns on this Embodiment is set to the magnitude | size which the toilet paper 30 does not collapse before opening in the packaging bag 10. FIG. That is, the dimensions of the packaging bag 10 are determined so that the toilet paper 30 is preferably wrapped almost exactly.

Next, the operation of the packaging bag 10 according to the present embodiment will be described.
According to the packaging bag 10 of this Embodiment, the toilet paper 30 which is the to-be-contained object formed in roll shape is accommodated in the form which arrange | positions four outer peripheral surfaces 30A in contact in the same plane.

  And the roll non-contact part which is the front 12 part between the toilet paper 30 arrange | positioned in the same plane in the side surface area | region 20 of the packaging bag 10 which covers 30 A of outer peripheral surfaces of the toilet paper 30, and is not contacting the toilet paper 30 A perforation 32 is formed only in C. At this time, the perforation extends linearly along the axial direction of the toilet paper 30 from a portion adjacent to the top surface region 28 of the packaging bag 10. The eyes 32 are formed in the side surface region 20.

  Therefore, according to the packaging bag 10 according to the present embodiment, even when the packaging bag 10 is lifted and carried together with the toilet paper 30 from the handle portion 24, the same in the side region 20 of the packaging bag 10 that is difficult to apply tension. The perforation 32 will be arrange | positioned in the part between the toilet paper 30 arrange | positioned in the plane. From this, when carrying the packaging bag 10 in which the toilet paper 30 is stored, the packaging bag 10 is not accidentally broken from the perforation 32.

  On the other hand, when opening the packaging bag 10 according to the present embodiment, it is not necessary to reduce the cut width of the perforation 32, so that even a weak consumer such as an elderly consumer can remove the packaging bag 10 from the perforation 32. It becomes easy to open and it becomes easy to take out the toilet paper 30 in the form of a roll.

  Furthermore, while it is necessary to make the perforation openable by consumers with weak power, in the present embodiment, it extends linearly along the axial direction of the toilet paper 30 formed in a roll shape. In addition to the perforation 32 being formed, the perforation 32 is formed in the side surface region 20 from a portion adjacent to the top surface region 28 of the packaging bag 10 covering the upper end surface of the toilet paper 30. Yes.

  From this, for example, compared with the case where the perforation 32 is formed in a direction intersecting with the axial direction of the toilet paper 30 or the perforation 32 is formed only at the lowermost portion of the side region 20 of the packaging bag 10. Thus, the required length S of the perforation 32 can be easily secured.

  On the other hand, in the present embodiment, the tie cut ratio of the perforation 32 is preferably a value in the range of 1: 4 to 1:15. In other words, according to the present embodiment, when the tie cut ratio of the perforation 32 is smaller than 1: 4, for example, 1: 3, the perforation 32 is hardly broken. On the other hand, when the tie cut ratio of the perforation 32 is larger than 1:15, for example 1:20, the packaging bag 10 is easily broken from the perforation 32 when the packaging bag 10 is carried. . For this reason, the range of the tie cut ratio of the perforation 32 is set to the above range.

  Here, the reason why the tie cut ratio is preferably set to a value in the range of 1: 4 to 1:15 will be specifically described. That is, samples each having a perforation 32 having respective tie cut ratios of 1: 1 to 1:20 shown in Table 1 below were first prepared.

  Then, with respect to these samples, the packaging bag 10 is carried for about 10 minutes in the state where the toilet paper 30 is accommodated, for example, so that a test is performed to determine whether or not the perforation 32 is inadvertently broken when the packaging bag 10 is carried. Is expressed as “strength”, and “◯” is given if the test result is satisfactory, and “x” is given if it is broken from the perforation 32 and there is a problem.

  On the other hand, the result of testing the ease of opening from the perforation 32 of the packaging bag 10 is expressed as “easy to open”, and if the test result of this ease of opening is very easy to open, “◎”, If it was easy to open, it was “◯”, if it was difficult to open, “△”, and if it was very difficult to open, “X”.

  According to the test results shown in Table 1, when the tie-cut ratio T: L is 1: 3 or less, which is less than 1: 4, the T perforations 32 are very In addition, when the tie cut ratio T: L is greater than 1:15 and greater than 1:20, since the L is too large, the perforation 32 is broken. It was confirmed that a value in the range where the above tie cut ratio is 1: 4 to 1:15 is good.

  In addition, in the said embodiment, although the to-be-contained object was the toilet paper, it may be a kitchen paper and the other roll-shaped article of a similar form may be sufficient. Moreover, although the polyethylene-made thing was employ | adopted as a packaging material which comprises the packaging bag of the said embodiment, you may employ | adopt the synthetic resin material which is plastic materials, such as a polypropylene and a polyethylene terephthalate. In the embodiment, the perforation is formed only on the front surface, but the perforation may be formed on the back surface.

  Furthermore, in the above-described embodiment, four toilet papers are stacked in four stages, and only twelve are stored. However, other eight, sixteen, or other numbers of toilet papers may be used. In other words, it is only necessary to store two or more per stage so that the outer peripheral surfaces are in contact with each other in the same plane. For example, two pieces are stacked in three steps to make six pieces, or other two steps, four steps or They may be stacked in a higher number of stages and accommodate other numbers. However, in this case, if the amount of toilet paper increases, the weight of the items to be stored also increases. Therefore, the thickness of the packaging material, the length of the perforation, the tie cut ratio, and the like are changed with respect to the above embodiment. For example.

  INDUSTRIAL APPLICABILITY The present invention can be used for storing sanitary products such as toilet paper and kitchen paper.
