The carton includes a front board, a rear board and both side boards, which are formed into a quadrangular cylindrical peripheral wall using folding lines. A bottom board and the partition board are formed consecutively via folding lines, respectively, as an extension from the lower end of the front board and as an extension from the lower end of the rear board. A superposing bottom board and a pasting board are formed via a folding line and a slant folding line, respectively, as an extension from the lower end of each of both side boards. Each superposing pasting board is pasted on each adjusting bottom board, and the partition boards are raised and superposed on each other to bisect a space between the front board and the rear board. The folding line between each bottom board and each partition board includes a branched folding line portion with a width that is formed at least one spot on the folding line. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a carton with a bisection partition having a partition that is integrally provided upright from the bottom of a paper carton.

Conventionally, among the cartons generally called auto-bottoms, that is, the bottom plates extending from the carton side plates, the adjacent bottom plates can be glued and foldable, respectively, and when glued, the glued bottom plates are expanded diagonally. In the carton that is opened and configured to lock the bottom part, the partition plate is mainly extended on the extension from the position of approximately half the carton thickness direction of the bottom plate, and each partition plate slides while bending when opening, There is known a technique in which a bisection partition is erected and formed inside a carton (see, for example, Patent Document 1).
JPO Gazette 56-35 “Collection of Well-known and Conventional Techniques (Sequel / Packaging Industry)” (page 106, Fig. 1)

  However, in the carton with a bisected partition by the well-known and conventional techniques described above, when each partition plate that forms a bisector partition inside the carton is bent at the time of opening, one of the partition plates is the other It was easy to occur to operate the partition plate. This is thought to be caused by variations in the bending strength of the fold line that becomes the bent portion, or partial variations in the carton lifting strength due to subtle misalignment that occurs in the carton folding and bonding process. The state that the board falls to one side and the function of the partition is not performed has occurred, and there is a problem that the work of raising the fallen partition board again has to be performed. In particular, this was a factor that hindered automation of box making and product filling operations.

  SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problem, and in a carton in which a partition plate is integrally formed upright from opposing bottom plates of an auto-bottom type carton, one of the partition plates at the time of opening However, there is a need to provide a carton with a bipartition partition that does not operate so as to knock down other partition plates, stably bisects a partition, and can automate box making and product filling operations.

  In order to solve the above-mentioned problem, the invention of claim 1 is composed of a single blank, and a front plate, a rear plate, both side plates, and the front plate and the rear plate, which form a rectangular cylindrical peripheral wall using a folding line. A bottom plate and a partition plate are continuously provided on the lower end extension of the both sides via a fold line, and a polymerization bottom plate and an adhesive plate are provided on the lower end extension of the both side plates via a fold line and an oblique fold line, respectively. In the carton that bisects the space between the front plate and the rear plate, and glues the bottom plate and the partition plate, respectively. A carton with a two-partition, characterized in that it is a fold line provided with at least one branched fold line part.

  The invention of claim 2 is characterized in that the interval between the fold line other than the branched fold line portion branched among the fold lines engraved between the bottom plate and the partition plate, and the fold line at the lower edge of the front plate and the rear plate, The carton with a bisected partition according to claim 1, wherein the interval between the front plate and the rear plate is slightly smaller than the bisected interval.

  In the carton with a bipartition partition according to the present invention, the fold line engraved between the bottom plate and the partition plate is a fold line provided with at least one branched wide fold line portion. When the plates are bent and slid and overlapped to form a bisection partition inside the carton, the partition plates overlap so that they press evenly and fall into either one Disadvantages can be eliminated. Since the partition plate is stably erected and formed on the inner side of the carton, there is no trouble that the product collides with the partition or is not stored in the partition even during the filling operation of the product. It is also possible to automate the work.

  Furthermore, in the carton with a bisected partition according to the present invention, the fold line engraved between the bottom plate and the partition plate is a fold line provided with at least one branched wide fold line portion as in the prior art. In addition, by design, the interval between the fold line engraved between the bottom plate and the partition plate and the fold line at the lower edge of the front plate and the rear plate is substantially the same as the interval between the front plate and the rear plate. When the same interval is used, the lower end of the front plate and the rear plate may be slightly expanded when the assembly of the carton is completed, causing the front and rear lower ends to swell as the finished dimensions of the carton. However, there is a drawback that rubbing occurs partially and the printed part is damaged. However, the interval between the fold line other than the branched fold line portion among the fold lines engraved between the bottom plate and the partition plate and the fold line at the lower end edge of the front plate and the rear plate is set to the front plate and the rear plate. By making the gap with the plate slightly smaller than the half of the gap, the finished size of the carton can be set in the same way as the upper end of the carton, and there is no partial bulging, etc. Etc., and the printed surface is not damaged.

  Next, in assembling the examples, when the standing state described in the previous section is raised to form a peripheral wall in the form of a rectangular cylinder using the fold lines L1, L2, L3, and L4, The bottom plate 10, the sticking plate 16, the superposed bottom plate 12 and the bottom plate 11, the sticking plate 17, and the superposed bottom plate 13 are respectively activated to form the bottom part, and the partition plates 14 and 15 extending from the bottom plates 10 and 11. Are folded and polymerized at a position where the space between the front plate 3 and the rear plate 1 is divided into two equal parts to form a bisection partition as shown in FIG. At the same time, in this embodiment, the engaging protrusions 23 and 22 protruding from the sticking plates 17 and 16 are fitted and engaged with the engaging holes 24 and 25 respectively formed in the folding lines L13 and L14. Maintains stable bottom formation. Thereafter, in the embodiment, predetermined contents are stored in the regions partitioned by the partition plates 14 and 15, respectively, the ear pieces 8 and 9 are folded, the top plate 6 is crowned, and the pre-polymerization plate 7 is then moved to the front. While superposing on the plate 3, the pasting portions 18 and 19 are glued to complete the assembly. In addition, in using the carton of the embodiment, the break lines L22 and L23 can be cut and opened from the insertion 20 provided in the central portion of the pre-polymerization plate 7, and the contents can be taken out.

  FIG. 4 is an explanatory partial cross-sectional view showing the operation of the partition portion in the state of FIG. 3, which differs from the actual cross-sectional view, but at the time of assembly of the present invention, the branch lines provided near the left ends of the folding lines L13 and L14, respectively. The function of the broken line portion is shown. In the embodiment, each of the bent fold lines L15 and L17 bulging toward the bottom plate side and the curved fold lines L16 and L18 bulging toward the partition plate side each have a spindle shape. With the formation, the opposing partition plates 14 and 15 are polymerized in the middle of the rear plate 1 and the front plate 3, that is, divided into two equal parts, and are pressed against each other by the action of the branched broken line portion. Become. This is because each of the branched bent line portions, that is, the spindle-shaped portion formed by the bent bent lines L15 and L16 and the bent bent lines L17 and L18 controls the folding of the bent lines L13 and L14, respectively. Are self-supporting without falling over while pushing against each other, and cannot be obtained with a linear folding line as in the prior art. In addition, in the embodiment, the branched fold line portion has a spindle shape using a curved fold line, but it is not limited to this, and the divergence of the abacus is a straight line in which the fold lines that are branched and opposed are parallel, It is good also as a rhombus shape. In addition, the branched broken line part can be designed in accordance with the shape change of the bottom plate, the partition plate, and the entire carton, but there is a disadvantage that the entire shape is distorted if the shape and size are extremely large. If the shape or size is too small, the above-mentioned effects may not be obtained.

  1, W1 described in the lower part of the side plate 2 is a depth dimension of the side plate 2, that is, a carton body depth dimension, and W2 described on the right side of the bottom plates 10 and 11 is a dimension between the folding lines of the bottom plate, respectively. Usually, in this kind of bisection carton, the dimension of W2 is designed to be half of W1. In the present invention, as described above, by providing a fold line portion branched between the bottom plate and the partition plate, the bottom plate and the partition plate portion facing each other by opening, the degree of extending the bottom depth dimension, It becomes larger than the case where the broken line is linear as in the prior art. For this reason, in the present invention, by setting the dimension of W2 to be slightly smaller than the dimension of half of W1 in advance, the degree to which the bottom plate and the partition plate portions facing each other by pushing up each other push each other and expand the bottom depth dimension is increased. This reduces the deformation of the carton due to the expansion of the bottom, and the deterioration of the surface printing portion due to the friction between the cartons during the accumulation of the carton. As a result of the prototype experiment, as a numerical value that is slightly smaller than half the dimension of W1, when using a paperboard having a basis weight of 300 to 450 g / square meter, about 1 mm is desirable.
