Description

  The present invention relates to a multi-pack and a multi-pack unfolding body in which three substantially cylindrical containers such as beverage cans and canned cans are packaged together.

  Beverage cans such as substantially cylindrical beer and juice, canned cans, and packaging items such as substantially cylindrical bottles (unless otherwise specified in the present application, the above-mentioned substantially cylindrical cans and bottles are referred to as cylindrical cans. The package for collectively packaging items such as ordinary rectangular cardboard boxes has many forms. Among them, a multi-pack made of cardboard that can be easily packaged by assembling six small cylindrical cans such as canned beer and is convenient for handling, carrying, and opening is well known (for example, see Patent Document 3).

  In addition, a multi-pack that wraps four or two even-numbered cylindrical cans is relatively known. For example, Patent Document 1 discloses a packaging package for fixing two can drinks with paperboard. ing. This packaging package is easy to handle and open, and has a structure in which the can beverage is difficult to drop off from the package during transportation.

  Although it is not well known about multi-packs that wrap an odd number of cylindrical cans, Patent Document 2 can wrap with a small amount of material, increasing the exposed part of the packaged object and exposing the display contents of the packaged object. A multi-pack for 3 cans is disclosed in which the appealing effect of the can is enhanced. As shown in FIG. 13, this multi-pack is a multi-pack in which three cans C are brought together and packaged, and the top plate 201, the bottom plate 202, the open plate 203 corresponding to the side wall, and the close plate 204 are connected. doing. The upright plate 203 projects to both sides, and an intermediate portion of the upright plate 203 is opened to form a sleeve 209. Holding pieces 206 are connected to both side edges of the top plate 201 and the bottom plate 202 and the upper and lower edges of the opening of the opening plate 203, and the pressing pieces 207 and 208 are connected to the outer edge of the opening plate 203 and both edges of the opening. Are connected.

  In order to wrap the can C with the multipack, the can C is inserted from both ends of the sleeve 209 and the opening of the open plate 203. Then, in order to fix the packaged cans, the holding pieces 206 folded inward are engaged with the protrusions on the upper and lower surfaces of each inserted can C, and are folded inward to the outer peripheral portion of the side surface of each can C. The pressing pieces 207 and 208 are elastically contacted.

  FIG. 14 shows another example of a multi-pack for three cans used for beer cans. In this multi-pack, side plates are arranged on three adjacent side surfaces of the three beer cans brought together, a part of the top plate and the bottom plate are folded inward, and the protrusions formed on the upper and lower edges of the beer cans The beer can is structured not to drop off from the multipack by using the portion to engage the folded portion with the projection. This multi-pack considers that the beer can which is a packaged object is exposed as much as possible by greatly reducing the amount of packaging material used. Thereby, the saving of packaging material resources, the visibility of beer can surface display, and the like have been improved.

  Multipacks that wrap three cylindrical cans together are packed in a multipack that is close to a regular rectangular parallelepiped because the bundled three cylindrical cans have a planar shape (top or bottom shape) close to a triangle or hexagon. difficult. For this reason, as shown in Patent Document 2 and FIG. 14, it is a multipack having a special upper surface and a bottom surface to be engaged with the top and bottom of the can, and a protrusion that can be engaged with the edge of the can is formed. Necessary.

  In addition, in general multipacks (6 cans multipacks), there are at least two finger holes on the top plate that can be used to carry fingers, so that the multipack can be carried with multiple fingers. Yes (Patent Document 3). However, in a multi-pack that packs three cylindrical cans together, the multi-pack top plate is intended to have two finger holes4 and the top plate portion corresponding to the top surface of the can to be packed is fingered. A hole must be provided and the finger cannot be inserted deeply, making it difficult to carry. Moreover, the 3-can multipack has a small top plate area in the first place (FIG. 14 and Patent Document 2), and if at least two finger holes are provided there, its strength becomes a problem. In particular, when handling heavy objects such as beer cans and juice cans, it is necessary to increase the strength of the paper material used to make the top plate withstand carrying.

  In this case, a relatively strong cardboard or the like is used for a package that wraps an object to be packaged with a certain amount of weight. However, if the cardboard strength is increased due to the certainty of packaging, opening becomes difficult. There is a fear. In order to facilitate the opening, as shown in FIG. 15, it is considered that the side plate (for example, two cut lines (breaking guide lines) parallel to the side plate and the top plate in the multipack of FIG. 14 are formed horizontally). However, when such a cut line is formed, the strength of the cut line portion is reduced, and there is a risk of breakage from this portion.

  Furthermore, when assembling multipack unfolding bodies to make multipacks and wrapping cylindrical cans, when the paper thickness increases, it is easy to engage top and bottom plates with can protrusions at the end of the assembly process. Therefore, it is difficult to engage the folding portion by engaging the engagement portion, and time and skill are required for assembly. In particular, if the side surface on which the above-mentioned cut line is formed is not carefully taken in the assembly process, the cut line is likely to be bent due to stress or the like in the engaging portion folding process, and the strength may be extremely reduced.

  Further, the multipack for the three cans described above is not configured to cover the entire top surface of the cylindrical can in any case. This is because the portion close to the outer periphery of the cylindrical can is covered by the difference between the shape of the entire top surface of the cylindrical can when the three cylindrical cans are bundled and the shape of the top plate such as a substantially hexagon covering the top surface. The need to cover the entire top surface of cylindrical cans because of the difficult structure and the purpose of packaging with multi-packs, such as the convenience of handling during transportation and loading, and the effect of exposing the inner can surface It is thought that it was because there was no.

  However, in the above-described multi-pack, it is impossible to prevent adhesion of dirt and bacteria on the top surface of a cylindrical can having a drinking mouth and a spout on the top surface like beer cans and juice cans. Recently, special attention must be paid to contamination caused by the attachment of influenza and food-toxic bacteria. For this reason, the necessity for the multipack of the structure which covers the whole top surface of a cylindrical can with a simple structure is increasing.

  An object of the present invention is to provide a multipack for packaging three substantially cylindrical objects to be packaged, which are easy to be surely grasped with a fingertip and easy to handle, and a multipack development body assembled as the multipack. Is to provide.

  Furthermore, a preferred object of the present invention is to provide a multipack that has sufficient strength, is less likely to cause a decrease in strength during assembly, and is easy to open, and the multipack developed body.

  Furthermore, a preferred object of the present invention is to provide the multi-pack deployment body that is easy to assemble and that is difficult to be unintentionally detached after assembly.

  Furthermore, the preferable objective of this invention is providing the said multipack which can coat | cover the whole top surface of a cylindrical can, and a multipack expansion body.

  The multipack of the present invention wraps three substantially cylindrical objects to be packaged together so that the side surfaces (body parts) are in contact with each other. The multipack of the present invention includes a substantially hexagonal top plate and a bottom plate covering the top surface and the bottom surface of an object to be packaged, and three side plates connecting the top plate and the bottom plate. The three side plates are respectively connected to the hexagonal sides of the top plate and the bottom plate that are not adjacent to each other. That is, the external appearance of the multipack of the present invention is close to the shape obtained by cutting the three triangular corners of the triangular prismatic container along the column direction. Then, the three substantially cylindrical objects to be packaged are bundled so that the cylindrical side surfaces (body portions) are in contact with each other, and are packaged in the multipack of the present invention. When the diameters of the objects to be packaged are the same, the top plate and the bottom plate of the multipack have a hexagonal shape obtained by cutting out three corners of an equilateral triangle.

  In the multipack of the present invention, a first opening and a second opening for inserting fingers for carrying are formed in the central part of the top board and the connection part of the side board with the top board, respectively. The first opening is formed in the central portion of the top plate, and corresponds to the boundary portion of the three cylindrical cans that are the objects to be packaged, and is disposed on the space. For this reason, it is a structure which is easy to operate the finger inserted from the opening inside the multipack. Although the number of the second openings may be one, it is preferable that each of the three side plates is provided. Moreover, it is preferable to provide the 2nd opening in the center part of the left-right direction of a side plate. The inner side of the central part in the left-right direction of the side plate corresponds to the boundary between the two cylindrical cans that are to be packaged, and a space is formed, so that the fingers inserted from the opening can be easily operated inside the multipack It is.

  In addition to the above-described configuration, the multipack according to a preferred embodiment of the present invention further has a cut line (breaking guide line) for opening on the side plate. The cut line is formed from the substantially central portion of the side plate toward the left and right sides, and the cut line toward the left side and the right side of the side plate is inclined in the opposite direction to the horizontal line. In other words, the cut line is formed in a V shape or an inverted V shape on the side plate. The cut line is a breaking guide line for breaking the side plate at the time of the multi-pack opening operation of the present invention, a plurality of discontinuities formed in a broken line, a perforation, a plurality of arrow blades formed discontinuously A conventionally known breaking guide line such as a cut line may be used.

  In the multipack of the present invention, the cut line is preferably formed by arranging a plurality of parallel short cuts having a slope on the same side as the cut line with respect to the horizontal line, and adjacent short cuts are More preferably, there is an overlap in the vertical direction of the multipack. Moreover, it is preferable that adjacent short cuts also overlap in a direction perpendicular to the direction of the cut. By making the cut line into such a shape, there is no risk that the side plate bends or breaks along the cut line when assembling the multi-pack, etc. Along the side plate, it can be opened and opened.

  It is preferable that a third opening for inserting a finger or a protruding part for gripping is formed at a position where the cut line toward the left and right sides intersects. When breaking the multi-pack side plate, even if there is no third opening or the like, the side plate can be broken by pressing near the intersection of the V-shaped cut line to break a part of the side plate and pulling up that part. However, if the third opening or the gripping protrusion is formed, the side plate can be easily broken from here.

  If the intersection of the V-shaped cut line and the third opening for inserting the finger are arranged near the center of the side plate, the intersection of the cut line and the third opening for inserting the finger are packaged items. Corresponding to the boundary between the two cylindrical cans, a space is formed inside the side plate, and the finger inserted from the opening can be easily operated inside the multipack.

  In the multipack of the present invention, it is preferable that the top plate completely covers the top surfaces of three objects to be packaged such as beer cans. Many beverage cans and food bottles, such as beer cans, have a drinking outlet and a content outlet on the top surface. When packaging with multipacks, completely cover the top surface of the packaged item. It is preferable that foreign matters such as dust and bacteria do not adhere. In order to completely cover the top surface of the object to be packaged, the shape of the top plate is deformed, for example, among the six side surfaces of the multipack, the side to which the side plate is not connected is shortened or the object is packaged It may be inflated in a convex shape according to the shape of the top surface of the object. In addition, what is necessary is just to deform | transform the shape of the bottom plate of a multipack similarly to the shape of said top plate in order to prevent the stain | pollution | contamination of the bottom face of a packaged article.

  When the multipack of the present invention exposes or covers a specific part of the surface of the packaged object, depending on the purpose, the strength of the multipack is not impaired so that it cannot be used. The shape of the side plate, the bottom plate, or the like may be changed to expose a part of the surface of the packaged object, cover it, or form an opening. In particular, make the central part of the side plate thinner so that the side surface of the packaged object is greatly exposed, or an opening or notch is provided in a part of the bottom plate so that a part of the bottom surface of the packaged object can be observed. Can do.

  The multipack deployment body of the present invention is a deployment body for assembling a multipack that wraps three substantially cylindrical objects to be packaged together so that the side surfaces (body portions) are in contact with each other. The multi-pack development body of the present invention is connected to the substantially hexagonal top plate arranged on the top surface of the three packages and the first side of the hexagon of the top plate, and the side surfaces of the three packages A first side plate disposed on the second side plate, a second side plate and a third side plate connected to the hexagonal third side and the fifth side of the top plate, respectively, and covering different sides of the package, It has a substantially hexagonal bottom plate that is connected to a side opposite to the side of the side plate that is connected to the top plate and covers the bottom surfaces of the three packages.

It is explanatory drawing of the conventional cut line.

Hereinafter, embodiments of the present invention will be described in detail.
[First embodiment]
A multipack according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a multi-pack which is a first embodiment of the present invention containing beer cans, FIG. 2 is a plan view of the multi-pack shown in FIG. 1, and FIG. FIG. 2 is a side view of the multipack shown in FIG. 1 (a front view when the left front in FIG. 1 is the front). The multi-pack 1 of this embodiment accommodates three beer cans 30, and the top surface of each beer can 30 is covered with the substantially hexagonal top plate 2. There are three side plates on the side surface of the multipack 1, and each side plate is connected to every other hexagonal side of the top plate 2. There is a gap between the side plates, and the surface of an object to be packaged such as the beer can 30 accommodated in the multipack 1 can be observed from this gap. The bottom plate of the multipack 1 has substantially the same shape as the top plate 2, and every other side of the substantially hexagonal shape is connected to a side opposite to the side connected to the top plate 2 of the three side plates. . The connecting portion between the bottom plate and the two side plates is engaged and connected by a detachable engaging piece.

  As shown in FIG. 1, the multi-pack 1 of the present embodiment stores three beer cans 30, and the top surface of each beer can 30 is covered with the top plate 2. By covering the entire top surface of the beer can 30 with the top plate 2 in this way, the multi-pack of this embodiment storing the beer can 30 can be applied to the top surface of the beer can 30 even if it is grasped with a bare hand during handling or in store display. There is no touch. Moreover, there is no fear of adhesion of foreign matters such as dust and bacteria. For this reason, the top surface of the beer can 30 with the drinking mouth is always kept hygienic. In addition, the beer can 30 is narrowed down from the shoulder portion, and the top surface has a smaller diameter than that of the trunk portion, so that the beer can 30 is easily covered with the substantially hexagonal top plate 2. In the case of a multi-pack that accommodates cylindrical cans with the same top diameter as that of the body, the length of the side that is not connected to the hexagonal side surface of the top plate 2 is reduced, or the shape of the side is convex. The entire top surface of the cylindrical can can be covered by adjusting to the shape of the top surface of the cylindrical can.

  As shown in FIGS. 1 and 2, a first opening 7 is provided at the center of the substantially hexagonal top plate 2 so that a finger can be inserted. Although the first opening 7 is triangular in FIG. 1, it may have any shape such as a circle, a rectangle, a hexagon, etc. as long as the operator's finger can be inserted, but it should not be unnecessarily enlarged. The first opening 7 preferably has a structure in which the inserted fingertip enters the gap between the two beer cans 30 and is hooked by the inserted fingertip with the inserted fingertip to easily lift the multipack. Moreover, it is preferable that the 1st opening 7 is made into the shape kept so that it may not reach to the top face of the stored beer can 30.

  The multipack 1 of the present embodiment includes a second opening for inserting a finger of a handler at the center of the top of each of the three side plates. The second opening only needs to be formed at the center of the uppermost portion of at least one side plate, for example, the side plate 3, but the multipack 1 can be handled when a similar second opening is provided in each side plate. Is convenient. If it demonstrates with the 2nd opening 8 of the side plate 3 shown in FIG. 1, the 2nd opening 8 may be what kind of shape as long as the operator's finger | toe can be inserted similarly to the 1st opening 7, and is unnecessarily large. It is better not to. Although the semicircular second opening 8 is shown in FIG. 1, it is preferable not to have a shape that cuts at an acute angle toward the top plate 2 side. If the top plate 2 is cut at an acute angle, stress is concentrated on the cut portion at the acute angle when the multipack 1 is lifted by putting a finger into the second opening 8, There is a risk of damage. In addition, since there is the second opening 8 at the center of the uppermost part of the side plate (connecting portion with the top plate), the fingertip inserted into the second opening 8 enters the gap between the two beer cans 30, and the fingertip is The multi-pack can be easily lifted by hooking the inside of the top plate 2.

  FIG. 4 shows a state where the multipack 1 of this embodiment in which the beer can 30 is stored is taken up by the operator. Usually, in order to lift the multipack 1 with one hand, the thumb is inserted into the second opening 8, the index finger or the middle finger is inserted into the first opening 7, and is lifted from the back side of the top 2. For this reason, you may form the 1st, 2nd opening 7 and 8 in consideration of the cross-sectional shape of each finger | toe. Note that the multipack 1 of this embodiment has a rotationally symmetric shape that is substantially the same when rotated from the top by 120 degrees when viewed from above, and the side plates 5 and 6 not shown in FIG. Second openings 9 and 10 similar to the opening 8 are formed. For this reason, the 1st opening 7 in the multipack of this form is made into the substantially equilateral triangle which is 120 degree | times rotation symmetrical form. Moreover, it is better not to form a portion cut at an acute angle in each opening so as not to cause stress concentration when the multipack 1 is lifted.

  The multipack of this embodiment may be provided with a fourth opening at a position facing the bottom surface of the beer can 30 of the bottom plate 4. The fourth opening is configured to allow confirmation of information displayed on the bottom surface of the beer can 30, such as the expiration date or the date of manufacture. The fourth openings are preferably provided at three locations corresponding to the bottom surfaces of the three beer cans 30. In addition, the size of the fourth opening may be a size within a range where information on the bottom surface of the beer can 30 can be confirmed.

[Second Embodiment]
A multipack according to a second embodiment of the present invention will be described with reference to FIGS. The multipack of the second embodiment of the present invention has the same overall shape as the multipack of the first embodiment, and the difference is shown in one of the side plates, for example, the side view of FIG. As described above, two cut lines (breaking guide lines) 18 are formed from the central portion of the side plate 5 toward the left and right sides. The cut line 18 is a guide line for breaking the side plate 5, which is also called a break line, a zipper, a perforation, or the like, and the guide line is usually formed in a broken line or a dotted line with fine cuts or small holes. Is.

  The cut line 18 in the multipack 1 of the present embodiment is inclined with respect to a horizontal line parallel to the top plate 2 or the bottom plate, and has an inclination. Further, the two cut lines 18 from the central part of the side plate 5 toward the left and right sides are inclined in opposite directions, and are formed in a V shape. A third opening 17 for inserting a finger is provided at the center of the side plate 5 where the two cut lines 18 intersect, and when the side plate 5 is broken, a finger is inserted into the third opening 17 so that the side plate By pulling the upper side of 5 outward, the side plate 5 is easily broken along the two cut lines 18. Thereby, the multipack 1 is opened.

  In the case where the third opening 17 is not provided, the side plate 5 may be broken as described above by pressing and breaking the intersecting portion of the two cut lines 18 and inserting a finger there. In addition, instead of the third opening 17, a cut line having a shape similar to the third opening 17 is formed at the position where the third opening 17 is formed, and this cut line portion is formed when the side plate 5 is broken. To form the third opening 17. Furthermore, instead of the third opening 17, a grip portion is formed at the position where the third opening 17 is formed, and the side plate 5 is broken by pulling the grip portion when the side plate 5 is broken. Also good.

  When the two cut lines are formed horizontally, the side plate is bent when the side plate and the bottom plate are engaged to assemble the multipack 1 to wrap the package, as already described with reference to FIG. Therefore, there is a risk that the side plate bends or breaks along the cut line, and attention must be paid to the assembly of the multipack 1. On the other hand, the cut line 18 in the multipack 1 of the present embodiment is formed in a V shape, and even if the side plate is curved, the side plate is hardly bent or broken along the cut line. The cut line 18 in the multipack 1 of the present embodiment is formed in a V shape, but the cut line 18 may be formed in an inverted V shape. In addition, the two cut lines 18 are preferably symmetric, but the smoothing may not be symmetric.

  As shown in FIG. 6, the inclination angle x of the cut line 18 with respect to the horizontal is 15 to 75 degrees, preferably about 25 to 60 degrees. Thereby, the breaking operation of the side plate 5 is facilitated, and undesired bending or breaking at the time of assembling the multipack 1 can be prevented.

  Each of the breaks 27 for breaking in the cut line 18 may be a conventionally known broken line shape, dotted line shape, arrow feather shape with auxiliary cuts having different angles in the broken line shape, etc. As shown, it is preferably formed by a large number of parallel cuts 27 formed in a step shape. Further, the cut line 27 is preferably inclined to the same side as the cut line 18 with respect to the horizontal line. The inclination angle y of the cut line 27 with respect to the horizontal line is equal to or smaller than the inclination angle x of the cut line line 18, and the cut lines 27 forming the left and right cut line lines 18 are symmetrical with each other. Adjacent cuts 27 overlap each other in a direction perpendicular to the horizontal line, and also overlap in a direction perpendicular to the cuts 27. The cut line having such a shape has a large resistance to the bending stress of the side plate 5, but can be easily broken in the breaking operation.

  The cut line 18 in the multipack 1 of the present embodiment is formed on the side plate 5, but may be formed on another side plate, top plate, or bottom plate. A plurality of cut lines 18 may be formed in one multipack 1.

[Third embodiment]
A multi-pack developed body according to a third embodiment of the present invention will be described with reference to FIG. The multi-pack development body of the third embodiment of the present invention is a sheet-like development body that can assemble a multi-pack without using an adhesive, other parts, or tools. The multipack developed body of this embodiment is usually made of cardboard, cardboard, or the like, but may be made of any material such as a plastic sheet, a metal plate, or a composite sheet thereof.

  FIG. 7 shows a plan view of the multipack developing body of this embodiment. In the multipack deployment body 100, three substantially rectangular side plates 3, 5, 6 are connected to every other hexagonal side of the substantially hexagonal top plate 2.
