PROBLEM TO BE SOLVED: To prevent a packaging material from being torn too much when a required quantity of respective products are taken out by providing a tear- guiding portion which can be torn by hand at locations on the packaging material which are confronted with the locations where respective products come into contact with, when the same shape products such as batteries are packaged under a state wherein a plurality of them are continued. SOLUTION: When the same shape products, e.g. four batteries B are packaged by collectively continuing them, at locations of a heat-shrinkable tube 1 corresponding with the directly above locations of the locations where respective batteries B come into contact with each other, a perforation 10 is provided in advance extending over the entire periphery. Then, by housing respective batteries B in the heat-shrinkable tube 1 and heating them, the heat-shrinkable tube 1 is shrunk and closely joined to respective batteries B, and they are tightly packaged. Then, by gripping one battery B and the remaining batteries B separately by both hands, and twisting them, the perforation 10 only at the location of the one battery B is torn, and the remaining three batteries are kept being packaged with the heat-shrinkable tube 1, and the packaging material is prevented from being torn too much.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a battery, a winding tape,
It relates to packaging materials for packaging multiple products of the same type, such as boxes of tissue paper, etc.More specifically, when trying to take out a required number of these products, do not break the packaging material too much. The present invention relates to a packaging material having a split inducing portion for making a crack.

[0002]

2. Description of the Related Art FIG. 14 shows a packaging material 3 in which five winding tapes T are packaged as a conventional example. The wrapping material 3 is a heat-shrinkable tube, which has a required diameter and is cut to a somewhat longer length, is put on a rolled tape T which is superimposed, shrunk by heating, and wrapped so as to be in close contact with the tape T It is.
The reason why the above-mentioned somewhat longer cutting is performed is to wrap the edges of the winding tape T at both ends inward. Reference numeral 30 indicates this entangled portion.

In order to take out the winding tape T from the packaging material 3, the packaging material 3 is torn like the tearing portion 30.

[0004]

However, even if it is desired to take out only one winding tape T, for example, there is a problem that the packaging material 3 may be broken too much depending on how much force is applied. If it breaks unnecessarily, it will be necessary to take out an unnecessary number of winding tapes T. However, if this happens, it will not be possible to restore it, and it will be inconvenient for handling such as transportation and storage. . If it is one, you want to take out only one and if you have two, you want to take out only two. Such a problem is not limited to the packaging material of the winding tape, but is generally observed in the packaging material for packaging a plurality of products of the same type. The present invention solves such a problem.

[0005]

According to the first aspect of the present invention, there is provided a packaging material for packaging a plurality of products of the same type, the packaging being opposed to a portion where each product contacts. This is attained by providing a packaging material provided with a crack-inducing portion that can be split by hand around a portion of the material.

A plurality of packaged products are originally separable, and are merely connected in close contact with a packaging material. So, for example, if one wants to take out only one of the products, if one puts a force to divide this one and the remaining part and squeeze them with both hands, the packaging material will be split from the split induction part and split, One of the products and the rest are split, and one of them may be taken out.

[0007] Since the remaining products are still wrapped in the packaging material, the products do not separate. In this way, a required number of products can be taken out.

A second aspect of the present invention is characterized in that, in the first aspect, the split guiding portion is provided at a portion of the packaging material corresponding to a portion directly above a portion where each product contacts. To do.

For example, in order to take out only one product, if this one is separated from the rest and the force is applied so as to squeeze with both hands, each product originally comes into contact only and is split directly above. Because the guide is provided, the force acts directly on the split guide and the packaging material is easily torn from the split guide.

[0010] Next, according to a third aspect of the present invention, in the first aspect, the split inducing portion is provided at a portion of the packaging material corresponding to a portion slightly shifted from immediately above a portion where each product contacts. It is characterized by having.

According to the second aspect of the present invention, when a force is unintentionally applied, the packaging material may be torn from the split guiding portion. This is because there is a split inducing portion right above the contact portion of each product, and it can be said that such a problem is liable to occur on the other hand while the product is easily broken. Therefore, a third aspect of the present invention is to prevent easy tearing without undesired force without impairing easiness of breaking. According to this, since the position of the contact portion of each product and the position of the split guiding portion are shifted, it is difficult for the product to be torn by an unintended force, but on the other hand, it can be split from the split guiding portion by a consciously applied force. I can do it.

A fourth aspect of the present invention is characterized in that, in the third aspect, the split inducing portion is provided on both sides of a portion directly above a portion where each product contacts. It was taken.

[0013] According to this, the wrapping material can be easily torn from the split guiding portion by the force applied intentionally.

Next, a fifth aspect of the present invention is characterized in that, in any one of the first to fourth aspects, the split inducing portion is a perforation.

The split guiding portion is provided to make the packaging material easy to tear. By forming a perforation in the packaging material with a knurl or the like in advance, the tear along the perforation can be performed. .

According to a sixth aspect of the present invention, in any one of the first to fourth aspects, the split induction portion is formed by reducing the thickness of the packaging material. The feature was adopted.

As in the case of the perforations described above, it can be said that the portion where the thickness of the packaging material is thin is a portion that is weak against the applied force. The thickness can be reduced by embossing or applying a hot iron.

Next, a seventh aspect of the present invention is characterized in that, in any one of the first to fourth aspects, the split guiding portion is provided intermittently.

The split guiding portion does not have to be provided continuously over the entire circumference of the packaging material.
It is literally a guiding part, or it should be able to make a trigger for splitting. Therefore, for example, it may be provided for one third of the circumference of the packaging material, or provided for half of the circumference. In the invention according to claim 7, the split induction portion is provided intermittently.

[0020] Next, the invention of claim 8 is characterized in that, in any one of claims 1 to 4, the split inducing portion is provided intermittently and stepwise.

In the above-described invention, the split guides are provided in two rows at one location to facilitate splitting. This is a combination of the configuration of the invention of claim 7 and the configuration in which the split guide is provided intermittently. This allows the rift to advance across the contact area of the product,
Resistant to unintentional forces.

Next, a ninth aspect of the present invention is characterized in that, in any one of the first to fourth aspects, the packaging material is a heat-shrinkable tube.

If a heat-shrinkable tube is previously provided with a split-inducing portion such as a perforation, and heat is applied over a mass of a plurality of stacked products, the tube shrinks and comes into close contact with the product to complete packaging. . Although packaging by heat shrink tubing is used in many fields, there is a problem in that it is difficult to break. However, if the split guiding portion is provided as in the present invention, it is easy to break the package. In addition, it is also possible to use a heat-shrinkable sheet without being limited to the tube shape.

Next, according to a tenth aspect of the present invention, in any one of the first to fourth aspects, the packaging material is a sheet, and after wrapping the product in the sheet, bonding is performed. It is characterized by the fact that it does.

The packaging operation is completed by wrapping a plurality of stacked products together as if wrapped in a furoshiki or wrapped in a pillow cover, and gluing the required portions together with glue or the like. Even with such a wrapping material, it often happens that it is difficult to break the wrapping without starting. In addition, the package may be broken excessively with excessive effort. However, if the split guiding portion is provided as in the present invention, it is easy to break the package.

Next, an eleventh aspect of the present invention is characterized in that, in any one of the first to fourth aspects, another split guiding portion substantially orthogonal to the split guiding portion is provided. did.

As described above, for example, in order to take out only one product, force is applied so that this one and the rest are separated and grasped with both hands. You may want to pinch and tear. Alternatively, there is a product such as a tissue paper box in which the strength of the product is low and the operation of breaking the package by folding is difficult. In such a case, if there is another split guiding portion provided in the direction in which a plurality of products are overlapped, the split guiding portion can be pinched and torn. While tearing from this other split induction part, if the product reaches the split induction part provided near the site where it comes into contact, each product will not be further torn apart, and each product will By tearing the splitting guide provided around the contacting part, it is possible to take out the required number of products and leave the remaining products packaged without separation. I can do it.

[0028] Next, according to a twelfth aspect of the present invention, in the eleventh aspect, the another split guiding portion substantially perpendicular to the split guiding portion is provided with a notch for facilitating a tear at an edge of the packaging material. It is characterized by having.

The cutout provided at the edge of the wrapping material serves as a starting point for starting to rip the other split guiding portion. Even without using scissors, the packaging can be broken with just the fingertips.

According to a thirteenth aspect of the present invention, in the eleventh aspect, the another split guiding portion substantially perpendicular to the split guiding portion is constituted by a tear tape provided along with a packaging material. It is characterized by having.

By pulling the tear tape, it is possible to tear the package easily and along the tear tape.

[0032] Next, the invention of claim 14 is characterized in that, in claim 11, the another split guiding portion substantially perpendicular to the split guiding portion is provided intermittently. .

[0033] Another split guiding portion substantially perpendicular to the split guiding portion plays an auxiliary role to the split guiding portion. For this reason, even if it is provided intermittently, the purpose of making it easy to break the package is sufficiently achieved. Another advantage is that the intermittent arrangement reduces the possibility of excessively breaking the package.

[0034] Next, a fifteenth aspect of the present invention is characterized in that, in the eleventh aspect, the another split guiding portion substantially perpendicular to the split guiding portion is provided intermittently and stepwise. And

According to this configuration, when excessive force is applied,
The problem of too much breakage of the packaging due to momentum is even less likely to occur. This is because the another split guiding portion is provided at a different level.

This is a packaging material in which a perforation 10 is provided in advance over the entire periphery of the heat-shrinkable tube 1 at a position directly above the position. 4
When the batteries B are placed in the heat-shrinkable tube 1 and heat is applied, the heat-shrinkable tubes 1 shrink and come into close contact with the four batteries B, which are tightly packed.

The packaging by the heat-shrinkable tube 1 is firm, and the shape of the four dry batteries B does not collapse. On the other hand, it is very difficult to break the heat-shrinkable tube 1 with a fingertip. For this reason, the heat-shrinkable tube 1 is broken by holding the dry batteries B with both hands and twisting them in the opposite directions. However, even when only one dry battery B is used, such as a timepiece, the heat-shrinkable tube 1 may be used. If all the batteries B are broken, all the batteries B will be separated, and the remaining batteries B will have to be stored separately.

However, according to the present embodiment, if one dry battery B and the remaining battery B are separated and gripped with both hands and folded, the heat-shrinkable tube 1 can be perforated at one dry battery B. 10, only the remaining three batteries B remain wrapped by the heat-shrinkable tube 1,
The handling is easy. In addition, since the dry battery B has a cylindrical shape, a perforation 10 between adjacent dry batteries B is used.
A portion of the heat-shrinkable tube 1 is floated from the dry battery B, and the package can be broken by simply pressing the perforation 10 from above.

(Second Embodiment) FIGS. 3 and 4 show a second embodiment of the present invention.
Are packaged together at the side portions thereof, and a perforation 10 is previously provided over the entire circumference in a portion of the heat-shrinkable tube 1 corresponding to a portion directly above a portion where the winding tapes T come into contact with each other. It is a packaging material consisting of In the figure, reference numeral 11 denotes a winding portion, which winds the corners of the winding tape T on both sides when the heated heat-shrinkable tube 1 shrinks and wraps the winding tape T.

When the present embodiment is divided into two hands at a required portion and gripped, twisted or broken, the heat-shrinkable tube 1 is torn from the perforated portion 10 and only a required number of winding tapes T are taken out. And the rest remains packaged.

(Third Embodiment) Next, FIG. 5 shows a third embodiment of the present invention. In the heat-shrinkable tube 1 of the second embodiment, another heat-shrinkable tube 1 substantially perpendicular to the perforation 10 is provided. A perforation 12 is provided. The perforation 12 extends to the edge of the winding portion 11.

In the present embodiment, it is possible to tear from the perforation 10 by twisting or folding with both hands.
When the heat-shrinkable tube 1 is torn from the perforation 12 at the edge of the first and torn to the perforation 10 between the required number of winding tapes T and the remaining winding tapes T, the perforations 10 are then joined. The heat-shrinkable tube 1 may be peeled off.

(Fourth Embodiment) Next, FIG. 6 shows a fourth embodiment of the present invention. The difference from the heat-shrinkable tube 1 of the third embodiment is that five winding tapes T are used. A perforation 17 was provided in a portion of the heat-shrinkable tube 1 corresponding to a portion shifted by 5 mm from directly above a portion where the two pieces contact each other. FIG. 6 schematically shows a state of the heat-shrinkable tube 1 before the heat-shrinkage.

As described above, in the case where the perforation 10 is provided at the portion of the heat-shrinkable tube 1 corresponding to the portion directly above the portion where the five winding tapes T are in contact with each other, a case where a force is unintentionally applied However, there is a case where the sheet is torn from the perforations 10. In other words, while it is easy to break, there is a possibility that such a problem may occur. However, according to the present embodiment, since the portion where the winding tapes T contact each other and the portion where the perforations 17 are provided are displaced, it is difficult for the unintended force to tear the portion. This makes it possible to tear from the perforations 17. In other words, it has succeeded in preventing it from being easily broken by unwilling force without deteriorating the ease of breaking.

(Fifth Embodiment) FIG. 7 shows a fifth embodiment of the present invention and relates to a packaging material for a tissue paper box P. Reference numeral 2 denotes a sheet-shaped shrink film, which is formed by wrapping five superposed tissue paper boxes P and then folding and gluing the margins on the upper and lower surfaces. Reference numeral 23 denotes an upper surface portion, which is a margin portion. Here, a perforation 22 is provided in advance in the shrink film 2 at a position corresponding to a position shifted by 15 mm from a position directly above a position where the five tissue paper boxes P contact each other.

In this embodiment, as in the fourth embodiment,
There is an effect that it is not easy to break with an unwilling force without impairing the ease of breaking.

(Sixth Embodiment) In the third embodiment,
The heat-shrinkable tube 1 of the second embodiment is provided with another perforation 12 substantially perpendicular to the perforation 10. The perforation 12 extends to the edge of the winding portion 11. Here, in the present embodiment, a notch 13 is further provided at the edge of the winding portion 11 where the perforation 12 is located.

The notch 13 serves as a starting point for starting to cut the perforation 12, and an effect is obtained that the package can be broken with only the fingertip without using scissors or the like. The shape of the notch 13 is V-shaped, but may be any shape such as U-shaped.

(Seventh Embodiment) In this embodiment, no perforation is provided. Instead, a tear tape 14 was provided alongside the heat-shrinkable tube 1. The tear tape 14 reaches the edge of the winding portion 11, and a notch 13 is provided at the edge.

When the end of the tear tape 14 in the notch 13 is now pulled, the heat-shrinkable tube 1

Another perforation 15, 16 is provided. However, the perforations 15 and 16 are provided in steps corresponding to the portion corresponding to the dry battery B. That is, another perforation substantially orthogonal to the perforation 10 is not continuous. When four batteries B are placed in the heat-shrinkable tube 1 and heat is applied, the heat-shrinkable tube 1 shrinks and adheres tightly to the four batteries B, and these are tightly packed.

In the present embodiment, the heat-shrinkable tube 1 can be cut from the perforation 16 by twisting or folding with both hands to break the perforation 10. If it goes, if it tears to the perforation 10 and this time, the perforation 1
The heat-shrinkable tube 1 is peeled off along with the tube. At this time, since there is no possibility of splitting from the perforations 16 to the perforations 15, each of the dry batteries B can be reliably and independently taken out. Also, the remaining dry battery B can be transported and stored in the packaged state as it is, so that it is easy to use.

The perforations 15, 16 may be provided intermittently instead of being provided at different levels. Also according to this configuration, it is possible to obtain an effect that splitting does not occur from the perforations 15 to the perforations 16. The configuration in which the perforations are provided intermittently can also be implemented for perforations provided on the entire periphery of the portion where the dry batteries B contact each other.
