Description

  The present invention relates to a packaging tool, and more particularly to a packaging tool for packaging a plurality of cylindrical containers together.

  2. Description of the Related Art Conventionally, various packaging tools for packaging a plurality of cylindrical containers for storing beverages such as soft drinks, beer or shochu are disclosed. For example, there is disclosed a product called a “multi-pack for cans” which has a cubic shape made of a plate-shaped cardboard material and stores six can containers therein (see, for example, Patent Document 1). In this multipack for cans, a strip-shaped handle is formed by cutting an upper part of a side plate from an upper plate. By grasping the strip-shaped handle, the multipack in which the can container is accommodated can be easily lifted.

  However, when the upper plate and the upper part of the side plate are simply cut to form the handle, there are the following problems. That is, when the can container is accommodated in the multipack without any gap, the cardboard material constituting the multipack is not deformed and it is difficult to insert a hand into the handle. On the other hand, if a large gap is provided between the multipack and the can container in order to enhance the deformability, there is also a problem that the can container is displaced from the multipack and sometimes falls off the multipack. .

  Packaging ties that can solve the above problems are also disclosed. As shown in FIGS. 6 and 7, the tying binder 101 is provided with two cut lines 124 to form the grip portion 125, and another cut line 130 is formed between the cut lines 124. (For example, see Patent Document 2). Another score line 130 is formed at a position corresponding to the upper edge of the can to be accommodated. For this reason, when the holding | gripping part 125 is lifted, the upper end of the binding tool 101 for packaging will adjoin the upper end side of a can, the cut line 130 will open, and the upper end edge of a can will enter. Therefore, the packaging binder 101 can be easily deformed. As a result, the grip 125 can be lifted upward greatly.

Further, a packaging binding tool in which a hole 208 for hooking the head of a bottle or the like that is a packaging object is also disclosed (see, for example, Patent Document 3). As shown in FIG. 8, the packaging tie is formed with an inverted triangular hole 208 at a position corresponding to the bottle head, and the bottle head is fitted into the hole 208 so that the bottle is displaced or moved. It is for suppressing.
JP 2001-328670 A (FIG. 2, summary) JP-A-8-2551 (FIG. 3, summary) Japanese Utility Model Publication No.7-11566 (FIG. 1)

  However, the packaging binder of Patent Document 2 has the following problems. That is, since the cut line 130 formed between the gripping portions 125 is short, the upper edge of the can immediately contacts both ends of the cut line 130 when the gripping portion 125 is lifted upward. And since the annular protrusion which generally constitutes a part of the upper lid is formed on the upper edge of the can, the protrusion bites into both ends of the score line 130, and a large stress is applied to each end. In some cases, both ends of the score line 130 are broken. Such a problem is particularly noticeable because the score line 130 is a simple linear cutting line.

  Moreover, since the packaging tie of the said patent document 3 aims at only suppressing the shift | offset | difference and movement of containers, such as a bottle, the hole 208 becomes a shape corresponding to the shape of a bottle. For this reason, when the handle 236 is pulled up, a force is applied to the lower edge of the hole 208 from the outer peripheral surface of the bottle, and simultaneously, a force from the head of the bottle is applied to both ends of the hole 208. As a result, the force generated when the handle 236 is pulled up is immediately applied to both ends of the hole, and a large stress is generated at both ends of the hole 208, so that the packaging binder is broken.

  For such a problem, the thickness of the packaging tool is increased, or the perforated line 130 described in Patent Document 2 and the periphery of the hole 208 described in Patent Document 3 are reinforced. It is also possible to make it difficult to break by reinforcing with a material. However, these means cause an increase in material cost, and in the latter means, such a reinforcing material becomes an obstacle, making it difficult to package the container or deteriorating the appearance of the packaging tool.

  Therefore, as a result of intensive studies to overcome the above-mentioned problems, the present inventor can solve the above-mentioned problems while using a paper material having the same thickness as the conventional one by devising the shape of the opening described later. As a result, the present invention has been completed.

  In order to solve the above-mentioned problems, the present invention provides a packaging tool for packaging a plurality of cylindrical containers, particularly in the invention of claim 1, each comprising an upper surface portion and a side surface each made of a plate-like material. And a bottom surface portion, two cutting lines are provided from the upper surface portion to each side surface portion to form a grip portion, and a boundary region between the upper surface portion and each side surface portion between the respective cutting lines. An opening having a predetermined width and height is provided, and when the grip is pulled up and the opening is close to the container upper end side, both ends in the width direction of the opening are at the container upper end. It has the characteristic that it forms so that the lower edge of an opening part may contact the outer peripheral surface of a container before contacting a part.

When configured in this way, even if the gripping portion is lifted, no large stress is applied to both ends of the opening. For this reason, breakage at both ends of the opening can be effectively prevented.
In the invention of claim 2, the width of the opening is such that the container upper end is at both ends in the width direction of the opening even when the grip is pulled up and the opening is close to the container upper end. The width is such that it does not contact. By comprising in this way, in addition to the effect | action of invention of Claim 1, since a force is not directly applied to the opening both ends from a container upper end part, the fracture | rupture of a packaging tool is prevented further.

  The invention according to claim 3 is characterized in that the opening has an inverted triangular shape. By configuring in this way, in addition to the operation of the invention of claim 1 or 2, the two sides of the triangle of the opening contact the outer peripheral surface of the container, and the external force is uniformly received at this portion. For this reason, the stress applied to each vertex of the opening is reduced.

  According to a fourth aspect of the present invention, the opening has a feature that a portion in contact with the outer peripheral surface of the container is formed in an arc shape. With this configuration, in addition to the effects of the invention of claim 1 or 2, the arcuate edge of the opening makes uniform contact with the outer peripheral surface of the container, so even when a large force is applied from the grip The force can be received uniformly at the arcuate edge. As a result, breakage of the packaging tool is effectively suppressed.

  The invention according to claim 5 is characterized in that a portion corresponding to the apex of the opening is formed in an arc shape. By comprising in this way, in addition to the effect | action of invention of Claims 1-4, even if stress is added to each vertex of an opening part, compared with the conventional linear opening part, stress is in one place. It becomes difficult to concentrate and breakage of the packaging tool is further suppressed.

  Further, the invention of claim 6 is characterized in that a cutting line that intersects a boundary line between the upper surface portion and the side surface portion is provided in the vicinity of both sides in the width direction of the opening. By comprising in this way, in addition to the effect | action of the invention of Claims 1-5, even when a packaging tool fractures | ruptures from the both ends of an opening part, a fracture | rupture stops at the said cutting line, and it progresses further. The

  In the packaging device of the present invention, since the wide opening is formed at the upper end portion of the packaging device, the lower edge portion of the opening portion is the container before the upper end portion of the container contacts the both ends of the opening portion. Since the force is received by the lower edge of the outer peripheral surface of the opening, breakage at both ends of the opening can be effectively prevented.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[Overview]
First, FIG. 1 is a development view of the packaging tool 1 according to the present embodiment. As shown in FIG. 1, the packaging tool 1 includes an upper surface portion 1A, side surface portions 1B ₁ and 1B ₂ that are continuous to both sides of the upper surface portion 1A, and a bottom surface portion 1C ₁ that is continuous to the side surface portions 1B ₁ and 1B ₂ . 1C ₂ are integrally formed with each other. Each member 1A, 1B ₁ , 1B ₂ , 1C ₁ , 1C ₂ is made of a thin paper material, and is bent at the boundary lines of the upper surface portion, the side surface portion, and the bottom surface portion. As a material, a cardboard material having a predetermined thickness may be used. Moreover, although the width W of the packaging tool 1 is variously selected according to the size of the can container to accommodate, in this embodiment, it is about 175 mm. The upper surface portion LA is about 125 mm, and the side surface portions 1B ₁ and 1B ₂ have LB ₁ and LB ₂ of about 170 mm.

In addition, stop portions 3 are formed at both ends in the width direction of the side surface portions 1B ₁ and 1B ₂ to prevent the containers from slipping down when the containers (for example, can containers) are packaged. Also, the two bottom surface portions 1C ₁ and 1C ₂ are configured to be about 125 mm, which is the same as the top surface portion 1A, by being coupled to each other. Bottom portion 1C _1, 1C ₂ bonds between the engaged projections 7 in the receiving hole 5 which is formed on one of the bottom portion 1C ₁ is formed in the other of the bottom portion 1C _2. Furthermore, it may be performed by joining the two with an adhesive. In addition, the broken line in a figure has shown the bending line.

Packaged in the packaging tool 1 of this embodiment is a cylindrical can container, the height is about 170 mm, the outer diameter of the body portion is about 66 mm, and the diameter of the tapered upper end is about 60 mm ( 2 and 6/16 inches). Moreover, the weight is about 500g per one. For this reason, when packaging six can containers as described later, the total weight is about 3000 g. However, these dimensions and weight are examples, and if the dimensions of each part of the can container change, the dimensions of each part of the packaging tool 1 change accordingly. In addition, the object to be packaged is not limited to a can container, and any object such as a food container can be used as long as it is a cylindrical container.
[Cutting line and gripping part]
Two cutting lines 13 having a predetermined curved shape for forming the grip portion 11 are provided on the upper surface portion 1A. Each cutting line 13 is formed to be symmetrical with each other, and the end of each cutting line 13 reaches part of the side surface parts 1B ₁ and 1B ₂ . The width of the region sandwiched between the cutting lines 13 is wide at the center, and once narrows in the direction of the side portions 1B ₁ and 1B ₂ . Furthermore, it becomes wider again toward the boundary region between the side surface portions 1B ₁ and 1B _2, and this portion has a so-called eight character shape. Similarly, the side wall portions 1B ₁ and 1B ₂ have an eight-letter shape. Here, the narrowest portion of the region sandwiched between the two cutting lines 13 exists on the upper surface portion 1A, and the width thereof is, for example, 30 mm. However, this value is an example, and may be 20 mm, 40 mm, or a value between them.

On the other hand, the wide central portion of the upper surface portion 1A has a width of about 72 mm. And in this wide part, the predetermined bending line 15 is formed so that a substantially triangle may be formed, respectively. Specifically, one side of the triangle is perpendicular to the width direction of the packaging tool 1, and the remaining two sides are inclined by about 30 ° with respect to the width direction. And the space | interval of the two bending lines 15 extended in the direction orthogonal to the width direction is equivalent to 30 mm of the narrowest part mentioned above. Further, the interval between the two cutting lines 13 on the boundary line between the upper surface portion 1A and the side surface portions 1B ₁ and 1B ₂ is about 110 mm.

In addition, the cutting line 13 of the present embodiment is not a complete cutting along the entire length, but is a discontinuous cutting line 13 where the portions remain joined. This is to prevent the gripping part 11 from floating before use of the gripping part 11 and hindering transportation. However, it goes without saying that it may be a continuous cutting line that is completely cut from the beginning. Furthermore, each end to reach the side surface portion 1B _1, 1B ₂ of the cutting line 13 has a substantially semicircular shaped portion 19 toward the inner side in the width direction of the packaging device 1. This is to prevent the packaging tool 1 from breaking at the end portion of the cutting line 13 even when a large load is applied to the grip portion 11 as will be described later.
[Aperture]
Next, the opening 21 formed between the _two cutting lines 13 and in the boundary region between the upper surface portion 1A and the side surface portions 1B ₁ and 1B ₂ will be described. When the can container is packaged, the opening 21 is an area where the upper end of the can container approaches or contacts. Specifically, when the gripping part 11 is pulled up and the opening 21 is close to the container upper end, the lower edge 21a of the opening is formed before both ends of the opening 21 in the width direction come into contact with the container upper end. Is formed in contact with the outer peripheral surface of the container. As shown in FIG. 1, the opening 21 has a substantially triangular shape. Two apexes are located in the vicinity of the boundary line between the upper surface 1A and the side surfaces 1B ₁ and 1B ₂ and the remaining apexes are side surfaces. It is located in the parts 1B ₁ and 1B ₂ . Therefore, when the packaging device 1 is assembled, the opening 21 is an upper surface portion 1A and the side surface portion 1B _1, 1B ₂ and the cross in the inverted triangle orientation. Each vertex 23 of the opening 21 is cut out in a predetermined arc shape. This is to prevent the packaging tool 1 from breaking at the apex 23. In addition, this opening part 21 may be comprised from the substantially square-shaped part which adjoins the container upper end part side, and the substantially triangular-shaped part which contacts the outer peripheral surface of a container (refer FIG. 5 (A)). .

  The width Wo of the opening 21 can be variously selected depending on the size of the can container to be packaged, but is about 51 mm in this embodiment. Therefore, when the relationship with the diameter of the upper end portion of the can container is about 60 mm, the relationship of the opening width Wo: upper end diameter≈5: 6 is established. When the ratio between the opening width and the container upper end diameter was determined so that such a relationship was established, it was clarified through experiments that the container upper end does not contact both ends of the opening 21 in the width direction. Further, the height (the vertical direction in the drawing) Lo of the opening 21 is about 21 mm. These values are examples, and the opening width Wo may be about 40 mm to 60 mm, and the height Lo may be about 10 mm to 30 mm.

Further, cutting lines (arc-shaped cutting lines) 25 are formed in the vicinity of both ends in the width direction of the opening 21 so as to be slightly separated from the opening 21. The arcuate cutting line 25 is curved in a direction along the arcs at both ends of the opening 21 (an arc that is convex outward in the width direction). The arcuate cutting line 25 can be selected in various ways. In this embodiment, the arcuate cutting line 25 is about 10 mm across the boundary line between the upper surface portion 1A and the side surface portions 1B ₁ and 1B ₂ .
[Action]
Next, the effect | action of the packaging tool 1 of this embodiment is demonstrated with reference to FIGS. FIG. 2 is a plan view and a front view showing a case where six can containers are packaged with the packaging tool 1 of the present embodiment. This figure shows a state where the gripping portion 11 has not been pulled up yet. As shown in the plan view of FIG. 2 (A), two can containers are arranged in two rows and packaged, and a gripping portion 11 is formed at a position corresponding to the center two. Moreover, as shown in the top view and the front view, the opening 21 of the packaging tool 1 is located at a position corresponding to the upper end of the central can container. However, the upper end portion of the can container is not in contact with each edge portion of the opening 21 in a state where the grip portion 11 is not pulled up as shown in the figure.

Next, FIG. 3 is a cross-sectional view taken along the line III-III in FIG. 2B, and particularly shows a state where the grip portion 11 is pulled up. In order to pull up the gripping part 11, the portions of the central part of the gripping part 11 that are curved outward are folded inside the packaging tool 1. At this time, since a triangular fold line 15 is formed in the curved portion, a part of the grip portion 11 is bent along the fold line 15 and easily enters the gap between the can containers. . Then, by inserting the finger under the grip portion 11 and gripping the grip portion 11, the grip portion 11 can be pulled up. When the gripping portion 11 is pulled up, the upper end portion of the packaging tool 1 is pulled toward the center of the gripping portion 11 accordingly. For this reason, the opening part 21 formed in the packaging tool 1 approaches the upper end edge of the can container.

  However, since the width Wo of the opening 21 is longer than that of the conventional one, the lower edge 21a of the opening is the outer periphery of the container before both ends of the opening 21 come into contact with the upper edge of the can container. Touch the surface. This point is also apparent from FIG. 4, which is an enlarged perspective view of the periphery of the opening 21. Accordingly, the stress is not concentrated on both end portions of the opening portion 21, and this portion does not break. Even if a large external force exceeding expectation is applied and both ends of the opening 21 are broken, the arc-shaped cutting line 25 is formed in the vicinity of both sides, so that the breaking stops at the arc-shaped cutting line 25 and beyond. Progression is suppressed.

  On the other hand, as described above, the two lower edges 21a of the opening 21 come into contact with the outer peripheral surface of the can container as the grip portion 11 is pulled up. At this time, since the opening 21 has an inverted triangular shape due to the two lower edges 21a, the opening 21 comes into contact with the outer peripheral surface of the can container in the long range of each lower edge 21a. For this reason, a large stress is not locally applied to each lower edge 21a, and since the lower edge 21a is a straight line, the packaging tool 1 is not broken from the lower edge 21a. Instead of the two lower edges 21a, the entire lower edge of the opening 21 may be formed in an arc shape that protrudes downward. Thus, by making the lower edge of the opening 21 that the outer peripheral surface of the can container contacts into an arc shape, the can container can be more uniformly contacted and the breakage of the packaging tool can be effectively prevented. . Moreover, this opening part 21 may be formed from the substantially square-shaped part which adjoins the container upper end part side, and the substantially arc-shaped part which contacts the outer peripheral surface of a container (refer FIG.5 (B)).

  In addition, as described above, in the packaging device according to the present embodiment, it is assumed that both ends in the width direction of the opening portion 21 are in contact with the upper end portion of the container, but the dimensions of the container and the material strength of the packaging device are also taken into consideration. Thus, it is possible to set so that both ends of the opening 21 do not contact the upper end of the container.

Further, as described above, the end portion of the cutting line 13 reaching the side surface portions 1B ₁ and 1B ₂ is formed as a semicircular arc-shaped portion 19 toward the center side of the packaging tool 1. In this way, when the end portion of the cutting line 13 is directed toward the center side, the packaging tool 1 is hardly broken at the end portion of the cutting line 13 even when a large force is applied to the grip portion 11.

  The present invention is a packaging tool manufactured from a material such as paper, and can be applied to a packaging tool for packaging a plurality of heavy can containers.

The expanded view of the packaging tool which concerns on one Embodiment of this invention is shown. It is a figure which shows the state which assembled the packaging tool disclosed in FIG. 1, FIG. 2 (A) shows a top view, FIG. 2 (B) shows a front view.
