  The present invention relates to a carton blank, and more particularly to a carton blank constituting a carton for accommodating a plurality of cylindrical objects to be packaged.

  Conventionally, in order to store and transport a large amount of cylindrical objects to be packed such as cans, a carton for arranging and arranging a plurality of cylindrical objects to be packed in a triangular shape in plan view. It has been known.

  Here, as a carton for accommodating the plurality of cylindrical objects to be packaged, the top surface and the bottom surface of each object to be packaged are covered with a pair of substantially triangular main walls, and are continuously provided on the two main walls. What coat | covers the surrounding surface of each to-be-packaged object by three rectangular-shaped side walls made is known (for example, refer patent document 1 and patent document 2).

  In the carton blank constituting the carton described in Patent Document 1, both end sides of one side wall are connected to one side of both main walls so as to be bendable. The other two side walls are constituted by a pair of side plates, and one side of each side plate is connected to the other two sides of both main walls so as to be bendable. And such a carton blank formed the carton which accommodates a several to-be-packaged object by adhere | attaching the other side of a both-sides board with an adhesive agent, respectively.

  Moreover, in the carton blank which comprises the carton described in patent document 2, the rectangular three side wall which coat | covers the surrounding surface of a to-be-packaged object is arranged in a row so that bending is possible, At positions where the peripheral surfaces of the objects to be packaged abut, holes that can be visually recognized from the outside of the carton are formed. Moreover, one side of a pair of substantially triangular main walls covering the top surface and the bottom surface of the package is connected to both ends of the side wall located at the center of the three side walls so as to be bendable. ing. Locking protrusions for connecting the main walls to the side walls are provided at portions of the other two sides of the main walls corresponding to the positions where the holes of the side walls are formed. And in such a carton blank, the carton which accommodates a several to-be-packaged object was formed by latching each latching protrusion to each hole.

  However, in the former carton blank, since both side plates are bonded using an adhesive, both side plates can be easily connected to form a carton, but the manufacturing cost increases.

  Further, in the latter carton blank, in the state where the package object is arranged inside the carton, the locking projection on the main wall is locked in the hole formed at the position where the peripheral surface of the package object contacts on the side wall. It has been difficult to make it difficult, and there has been a problem that the efficiency of the work of storing the packaged items in the carton is reduced.

  As shown in FIGS. 1, 2, and 3, the carton blank 1 includes a first main wall 3 having a substantially hexagonal shape that covers a part of the top surface 2 a of each can 2, and a bottom surface of each can 2. It has the 2nd main wall 4 of the magnitude | size which covers a part of 2b.

  Here, in the inside of the carton 5 constituted by the carton blank 1, three cans 2 are arranged in a first row where one can 2 is arranged, and two cans 2 adjacent to the first row. Are arranged and arranged so that the planar shape is a substantially equilateral triangle shape by a total of two rows including the second row arranged in parallel.

  The adjacent six sides of the first main wall 3 and the second main wall 4 are alternately connected side 7 and 9 and opening side 8 and 10, respectively.

  One end side of the rectangular first connection wall 12 is connected to the first connection side 7a of the connection sides 7 of the first main wall 3 via a folding line 13. The other end side is connected to the first connection side 9 a among the connection connections 9 in the second main wall 4 via the folding line 14.

  One end side of the rectangular second connection wall 16 is connected to the second connection side 9b among the connection sides 9 of the second main wall 4 via a folding line 17. A rectangular folding piece 19 is connected to the other end side of this through a folding line 18.

  Similarly, one end side of the rectangular third connection wall 20 is connected to the third connection side 9c among the connection sides 9 of the second main wall 4 via a folding line 21, A rectangular folding piece 23 is connected to the other end side of the connection wall 20 via a folding line 22.

  A protruding tab 24 as a locking means for connecting the first main wall 3 and the second connection wall 16 is formed on the second connection side 7b of the connection sides 7 of the first main wall 3 by a folding line 25. And projecting from the second connection side 7b. Similarly, a protruding tab 26 as a locking means for connecting the first main wall 3 and the third connection wall 20 is provided on the third connection side 7c among the connection sides 7 of the first main wall 3. It protrudes from the third connection side 7 c via the folding line 27.

  The projecting tabs 24 and 26 are formed at positions corresponding to the gaps between the cans 2 arranged at predetermined positions inside the carton 5. In the present embodiment, the projecting tabs 24 and 26 are formed at the center portions of the connection sides 7 b and 7 c. Is formed.

  When the folding lines 13, 14, 17, 18, 21, 22 of the carton blank 1 are bent between the second connection wall 16 and the folding piece 19 to form the carton 5, the first main wall 3 A tab insertion hole 29 as a locking means is formed by a cutting line 30 at a position facing the protruding tab 24 formed on the second connection side 7b. Similarly, between the third connection wall 20 and the folding piece 23, a tab insertion hole 31 as a locking means is provided at a position facing the protruding tab 26 formed on the third connection side 7 c of the first main wall 3. Is formed by the cutting line 32.

As shown in FIG. 2, each opening side 8 of the first main wall 3 has a length dimension L ₁ shorter than a diameter dimension D of the top surface 2 a of the can 2, and the second main wall. each opening edges 10 of 4 their length dimension L ₂ is shorter than the diameter of the bottom surface 2b of canned 2.

  The length L of each of the opening sides 8 and 10 is such that when the carton 5 is formed by the carton blank 1, the opening 33 constituted by each of the opening sides 8 and 10 and both sides of each of the connection walls 3 and 4. Therefore, it is preferable that the diameter is an approximate value of the diameter D of the top surface 2a or the bottom surface 2b of the can 2 as long as the cans 2 accommodated in the carton 5 do not fall out. Thus, by making the length dimension L of each open side 8 and 10 an approximate value of the diameter dimension D of the top surface 2a of the can 2, the material of the carton blank 1 can be saved, and the carton 5 Each canned product 2 itself housed inside can be easily visually confirmed.

Here, since the top surface 2 a of the can 2 is formed to be slightly smaller than the bottom surface 2 b, the length dimension L ₁ of each opening side 8 of the first main wall 3 is the _first when the carton 5 is configured. It is slightly shorter form compared with the length L ₂ of each opening edge 10 facing the second main wall 4.

In addition, support pieces 34 protruding from the third connection side 7 c are connected to both end portions of the third connection side 7 c in the first main wall 3. Each supporting piece 34, a protrusion dimension O of the support pieces 34, the dimension obtained by adding a length dimension L ₁ of the opening edge 8 of coordinating adjacent to the third connecting side 7c is third in the second main wall 4 They are formed to the same as the length L ₂ of each opening edge 10 of coordinating next to the connecting side 9c.

  Next, the operation of this embodiment will be described.

  In order to accommodate each can 2 in the carton 5 constituted by the carton blank 1, first, the three cans 2 are arranged at predetermined positions so that the bottom surface 2b of each can 2 faces the inner surface of the second main wall 4. . Subsequently, the folding lines 13, 16, 20 are arranged so that the inner surfaces of the cans 2 are opposed to the peripheral surface 2 c of the cans 2, and the inner surfaces of the first main walls 3 are opposed to the top surface 2 a of the cans 2. 14, 17, and 21 are folded into mountain folds, and the folding curves 18 and 22 are folded into mountain folds so that the outer surfaces of the folding pieces 19 and 23 are in contact with the inner surface of the first main wall 3. Fold it in.

  Then, the folding lines 25 and 27 are bent into mountain folds, and the protruding tabs 24 and 26 are inserted into the tab insertion holes 29 and 31. At this time, the protruding tabs 24 and 26 and the tab insertion holes 29 and 31 are formed at positions corresponding to the gaps between the cans 2 arranged inside the carton 5, and the tabs are inserted inside the carton 5. The vicinity of the holes 29 and 31 is a gap. For this reason, since there is a margin in the formation positions of the tab insertion holes 29 and 31 and the protruding tabs 24 and 26, the protruding tabs 24 and 26 can be smoothly inserted into the tab insertion holes 29 and 31, respectively.

  Thereby, the package 35 which accommodated each can 2 in the inside of the carton 5 can be comprised.

  As described above, according to the present embodiment, the protruding tabs 24 and 26 and the tab insertion holes 29 and 31 are formed at positions corresponding to the gaps between the cans 2 arranged inside the carton 5. The vicinity of the tab insertion holes 29 and 31 inside the carton 5 is a gap.

  Therefore, since there is a margin in the formation positions of the tab insertion holes 29 and 31 in the carton blank 1, the protruding tabs 24 and 26 can be easily inserted into the tab insertion holes 29 and 31. Moreover, since each can 2 is not located in the position which inserts each protrusion tab 24 and 26, it can insert smoothly, without making each protrusion tab 24 and 26 contact | abut to the surrounding surface 2c of each can 2. . Thereby, each canned product 2 can be efficiently accommodated in a carton without using an adhesive.

The support piece 34 formed in the third connecting side 7c of the first main wall 3, and their projecting dimension O, and the length L ₁ of each opening edges 8 coordinating adjacent to the third connecting side 7c The added dimension is formed to be the same as the length dimension L ₂ of each opening side 10 adjacent to the third connection side 9 c in the second main wall 4. For this reason, when the packaging body 35 is placed so that the third connection wall 20 is at the bottom, the packaging body 35 can be positioned substantially perpendicular to the placement surface by being supported by each support piece 34. The package 35 can be placed stably.

  In addition, this invention is not limited to the said embodiment, A various change is possible as needed.

  For example, in the present embodiment, the carton blank 1 that accommodates the tapered can 2 has been described. However, the present invention is not limited to this, and the top surface 2a and the bottom surface 2b have a cylindrical shape having the same diameter dimension D. It may contain a packaged item. In this case, it is not necessary to form each support piece 34.

  In the present embodiment, the locking means is constituted by the protruding tabs 24 and 26 and the tab insertion holes 29 and 31, but is not limited thereto, and is arranged at a predetermined position inside the carton 5. What is necessary is just to form in the position corresponded to the gap | interval of each canned product 2 to be.

  Further, the second connection wall 16 and the third connection wall 20 are connected to the second main wall 4, but may be connected to the first main wall 3.

  Furthermore, the second connection wall 16 and the third connection wall 20 are constituted by a pair of connection pieces, one end side of the pair of connection pieces being the first main wall 3, and the other end side being the second main wall. 4, the locking means for locking each connection piece may be formed at a position corresponding to the gap between the cans 2 on the other end side of each connection piece.

  Further, in the present embodiment, the description has been given using the case where the three cans 2 are arranged and accommodated so that the planar shape becomes a substantially equilateral triangle shape. What is necessary is just to arrange and arrange in the shape. For example, six items to be packaged are a first row in which one can 2 is arranged, a second row in which two cans 2 are arranged in parallel adjacent to the first row, and a second row. It can be used in the case where the planar shape is accommodated in a substantially triangular shape by a total of three rows including the third row in which three cans 2 are arranged in parallel.
