JP-A-9-301347 Japanese Utility Model Publication No. 1-76409

  In order to assemble the upper part of the box, the paper box with a handle described in the cited document 1 is constructed by stacking and stacking a pair of handle components, and then bending the first pressing piece so as to overlap with the second holding piece. The process of bending to the cover plate side is necessary, and the workability is not so easy. In addition, since the lid plate constituting piece is connected to the upper ends of the pair of opposing side wall constituting pieces, and the handle constituting pieces connected to the pair of lid plate constituting pieces overlap each other to form the handle, the side wall, the lid plate, the handle Is not a cylindrical integral with four creases in common, so that the weight of the contents on the bottom wall is received by the two side wall constituent pieces and the lid plate constituent pieces connected to them. Therefore, there is a problem that it is weak in strength when suspended. Furthermore, since the handle has only a double structure except for the portion where the first pressing piece overlaps, there is also a problem that it is easy to tear off when a heavy content is stored and suspended.

  The one-touch sealed box described in the cited document 2 is not easy to assemble because the lower end of the folding plate is inserted into the locking notch provided inside the side plate, and is inserted if the contents are heavy. It is a weak structure where the part is removed. Moreover, since the handle plate described in Patent Document 2 is also only a double structure, there is a problem that it is easily broken when suspended.

  Each of the cited documents 1 and 2 is a general rectangular box, and in order to differentiate it from competing products, it depends only on the size and surface printing, and in terms of shape, it is a storefront. There is a problem in the design that the display effect when arranged in the same manner is small.

  The present invention has been made in view of such problems, and its object is a shape with a high display effect that can be differentiated from competing products at stores, etc., and the assembly work is simple. Another object of the present invention is to provide a carry carton having a handle having strength corresponding to a heavy object.

In order to achieve the above-mentioned object, the present invention comprises a blank having four side plates and a glue margin plate that are arranged in series in the vertical direction through main ruled lines that are parallel to each other. Glue the back side of the sack and sack affix to a square tube, assemble the bottom of the tube to form a flat bottom closure, then each triangle on the top of each side plate with a ruled line A carry carton in which a top closure is formed by assembling a roof panel and a handle panel portion above the roof panel,
An upper point and a lower point, which are one side of the roof panel, are defined at the upper part of the pair of opposing main ruled lines, and the upper point of the other pair of opposing main ruled lines is located between the upper point and the lower point. A point is defined, and each side plate is formed with an upper auxiliary ruled line connecting the upper point and the middle point, and a lower auxiliary ruled line connecting the lower point and the middle point, and these upper auxiliary ruled line and lower auxiliary ruled line are the two remaining sides of the roof panel. And
The roof panel and the handle panel, which are partitioned at the upper part of a pair of opposing side plates, have a center point where the distance from the midpoint of the upper auxiliary ruled line is half of the square diagonal line, and passes through the center point from the lower point. A broken line leading to the edge of the handle panel
The roof panel partitioned at the upper part of the pair of opposing side plates and the handle panel on the upper side are folded at the fold line so that the folded roof panel is inclined inward by the lower auxiliary ruled line and overlaps with it. The roof panel defined on the upper side of the other pair of side plates facing each other is inclined inward by the lower auxiliary ruled line, and the other pair of side plates facing each other is sandwiched between the valley-folded handle panels. A handle panel is formed on the upper side of the opposed inclined surface of the roof panel by a handle panel continuously provided on the roof panel partitioned in the upper part.

  In the carry carton configured as described above, it is preferable that the bottom closing portion formed at the lower portion of the square tube is an auto bottom.

  Carry carton of the present invention is a sack pasting of a blank, raising the sack pasted in a square tube, forming a bottom closing part and putting a product inside, then forming a top closing part However, the top closing part faces the handle panel that is connected to the roof panel defined on the upper part of the pair of opposing side plates so that the fold line of the handle panel is folded, and grips the handle panel part with both hands. By simply closing the handle panel connected to the roof panel defined on the upper part of the other pair of side plates, the roof panel defined on the upper part of the pair of opposing side plates is also bent in the same manner as the handle panel. By the way, it is folded in the valley, and the roof panel partitioned on the upper part of the other pair of side plates overlaps the roof panel folded in the valley, so that the inclined surface is completed. It can be easily performed in the pitch.

  In the carry carton of the present invention, the triangular roof panel that constitutes the top closing part and the handle panel on the upper side thereof are partitioned on the upper part of the side plate, and each constituent part from the bottom closing part to the top closing part Is made of a single blank with no ruled cuts, so it has a cylindrical integrated shape that can be applied by sacking, so the weight of the contents on the bottom is reduced to 4 side plates, The handle panel will receive evenly, and it has a strong structure as a box body, and the top closure part is composed of a triangular inclined surface with one side of a square diagonal line, and this inclined surface is an overlapping triangle As a result, the handle connected to the inclined surface is formed of four paperboards, which is heavy in terms of strength. It has become but also can respond.

  Further, in the carry carton of the present invention, the trunk portion is a quadrangular prism, but the top closing portion is composed of two triangular inclined surfaces of the same shape with one side of a rectangular diagonal line, and these inclined surfaces have diagonal lines. Since it has a roof-like shape with the base diagonally located below the base, it has a higher display effect than a simple square box, and is differentiated from competing products in stores, etc. Can be achieved. In addition, by adopting such a form, when assembling the handle by bringing the handle panel together, an effect of facilitating the assembly is generated due to the force of joining the two handle panels.

  That is, an upper point X and a lower point Y, which are one side of the roof panels 11, 21, 31, 41, are defined at the upper part of the pair of main ruled lines a, c facing each other after assembling. A midpoint Z located between the upper point X and the lower point Y is defined above the pair of main ruled lines b and d, and the upper point X and the four side plates 10, 20, 30, and 40 are An upper auxiliary ruled line m connecting the middle point Z, a lower auxiliary ruled line n connecting the lower point Y and the middle point Z are formed, respectively. The upper auxiliary ruled line m and the lower auxiliary ruled line n are formed on the roof panels 11, 21, 31, 41. The remaining two sides. Furthermore, handle panels 12, 22, 32, and 42 are partitioned by upper auxiliary ruled lines m above the four side plates 10, 20, 30, and 40, respectively.

  Further, the roof panels 11 and 31 and the handle panels 12 and 32 partitioned on the upper portions of the pair of side plates 10 and 30 that face each other after assembling have a distance from the midpoint Z of the upper auxiliary ruled line m that is half of the square diagonal line. A broken line p extending from the lower point Y through the center point O to the edges of the handle panels 12 and 32 is provided. The broken line p is formed of a lead rule having a cut in the middle of the ruled line in consideration of the ease of bending.

  As shown in the figure, the handle holes 12a and 32a are formed at the positions around the broken line p by the cut lines that circulate around the upper auxiliary ruled line m as shown in the figure. One of the remaining handle panels 22 is formed with a locking piece 22b at a position symmetrical to the handle hole 12a of the handle panel 12 by a cutout line that leaves the upper auxiliary ruled line m, and the other remaining In the handle panel 42, a handle hole 42a is formed at a position symmetrical to the handle hole 32a of the handle panel 32 by a cut line that goes around the upper auxiliary ruled line m as one side.

Bottom of the blank B ₁ represents, bottom closure portion is designed to form an auto bottom. In other words, large triangular bottom outer flaps 13 and 33 having small triangular folded adhesive margin pieces 14 and 34 are defined by ruled lines e and f, respectively, below the pair of side plates 10 and 30 facing each other after assembly. In addition, trapezoidal bottom inner flaps 23 and 43 are defined by ruled lines g and h at the lower portions of the other pair of side plates 20 and 40 that face each other after assembly. In addition, the ruled lines i and j at the boundary between the bottom outer flaps 14 and 34 and the folded adhesive margin pieces 14 and 34 are each made of a lead ruled with a cut in the middle in consideration of ease of folding.

The procedure for assembling the blank B ₁ shown in FIG. 2 to form the carry carton C ₁ shown in FIG. 1 is as follows.

First, as shown in FIG. 3, the bottom outer flaps 13 and 33 are folded inward along the ruled lines e and f, and the bottom inner flaps 23 and 33 are folded back inside along the ruled lines g and h. Next, the folded paste margin pieces 14 and 34 are folded at the ruled lines i and j, the folded glue margin pieces 14 and 34 are bonded to the bottom inner flaps 14 and 34, respectively, and the glue margin plate 50 is placed on the opposite side. The blank B ₁ is put into the sack pasting state as shown in FIG. 4 by being pasted and folded on the back side of the front end of the side plate 40. Then, supplies blank B ₁ which is the state thus sack attached to the filling process.

In the filling step, the cause blank B ₁ that the folded rectangular tube of a square, assembled at the bottom of the rectangular tube, as shown in FIG. 5, to form the bottom closure portion. That is, by the operation of raising the folded blank B1, the bottom inner flaps 23, 33 and the bottom outer flaps ₁₃ , 33 are automatically locked, and a flat auto bottom is easily formed at the bottom.

After forming the bottom closing portion in this way, the product is put as contents, and the triangular roof panels 11, 21, 31, 41 and the upper handle panels 12, which are partitioned by ruled lines at the top of each side plate, 22, 32 and 42 are assembled to form a top closure. Thereby, the carry carton C ₁ with a handle shown in FIG. ₁ is formed.

  In order to form the top closing portion, the handle panels 12 and 32 connected to the roof panels 11 and 31 defined on the upper portions of the pair of side plates 10 and 30 facing each other are folded at the fold line p. The roof panels 21, 41 that are picked so as to straddle the handle panels 12, 42 with the other hand and straddle the handle panels 22, 32 with the other hand and are partitioned on the upper side of the other pair of side plates 20, 40 that face each other as they are. The handle panels 22, 42 that are continuously provided are connected to each other. By performing this operation, the roof panels 11 and 31 partitioned on the upper part of the pair of opposing side plates 10 and 30 are also valley-folded at the broken line p in the same manner as the handle panels 12 and 32, and the roof panel is folded in the valley. The roof panels 21 and 41 defined on the upper portions of the other pair of side plates 20 and 40 are overlapped with each other to complete the inclined surfaces. The inclined surface formed in this manner is a triangle with the base of a diagonal line corresponding to the quadrangular prism.

  After that, through the overlapped handle holes 12a, 32a, 42a, the locking piece 22b defined in the handle panel 22 is projected to the opposite side, and the locking piece 22b is taped to the top of the inclined roof panel 41. Thus, the top portion can be closed.

In the present invention, when designing the blank B _1, it is possible to determine the shape of the roof panels 11, 21, 31 and 41 in the following manner. A method for determining the shape will be described with reference to FIG.

For example, when the square column is a regular square column having a side length t ₀ of 116 mm and the angle θ of the inclined surface is 30 degrees, the length of each part is defined by the relational expression of the three sides in the right triangle and the definition of the trigonometric function Is obtained as follows.
・ Diagonal length of square pillar t ₁ = t ₀ × √2 = 164.05 mm
-Length between middle point Z and center point O t ₂ = t ₁ /2=82.02 mm
・ Height between the center point O and the lower point Y t ₃ = t _{2 /} tan 30 ° = 47.36 mm
-Length between the center point O and the lower point Y t ₄ = t ₃ × 2 = 94.71 mm
-Length t ₅ between lower point Y and middle point Z: √ (t ₂ ² + t ₄ ² ) = 125.29 mm

Thus, the length of the three sides, that is, the length t ₂ between the center point Z and the center point O: 82.02 mm, the length t ₄ between the center point O and the lower point Y: 94.71 mm, By determining the length t ₅ between the lower point Y and the middle point Z: 125.29 mm, the inclination angle φ (see FIG. 2) of the broken line p from the main ruled line (a, c) is determined to be 27 degrees. Is done.

FIG. 7 is a perspective view showing another example of the carry carton according to the present invention, and this carry carton C ₂ is formed by assembling a blank B ₂ whose development is shown in FIG.

In the carry carton C ₂ formed by assembling the blank B ₂ , the roof panels 11, 21, 31, 41 are overlapped in the same procedure as described above to form a triangular inclined surface. As shown, the inclined surface is basically a triangle with the base of a quadrilateral diagonal corresponding to a quadrangular prism, the base curved slightly downward, and the other two downward hypotenuses pointed at the center. It becomes a shape. Incidentally, the handle panels 12, 22, 32, 42, so not provided locking piece 22b as in the previous blank B _1, it is necessary to fix by using an appropriate tapes after overlapping.

FIG. 9 is a perspective view showing another example of the carry carton according to the present invention, and this carry carton C ₃ is formed by assembling a blank B ₃ whose development is shown in FIG. The blank B ₃ is also similar to the blank B ₂ in FIG. 7, triangular roof panel and the other shape of the upper handle panel, has the same configuration as the blank B ₁ in FIG. 2 described above, Similar parts are denoted by the same reference numerals, and detailed description thereof is omitted.

In the blank B _{3 of} FIG. 10, the upper auxiliary ruled line m of the upper auxiliary ruled line m and the lower auxiliary ruled line n that are the two sides of the triangular roof panels 11, 21, 31, 41 is formed in an arc shape downward. In addition to the curved shape, the lower auxiliary ruled line n is also curved in a circular arc shape downward. In consideration of the ease of bending, the upper auxiliary ruled line m is a lead ruled with a cut in the middle of the ruled line.

In the carry carton C ₃ formed by assembling the blank B ₃ , the roof panels 11, 21, 31, 41 are overlapped in the same procedure as described above to form a triangular inclined surface. As shown in the figure, the inclined surface is basically a triangle with the base of a quadrilateral diagonal corresponding to a quadrangular prism, the base is curved slightly downward, and the other two downward hypotenuses are also curved slightly downward. It becomes the shape.

  The embodiment of the present invention has been described in detail with reference to three examples. However, the carry carton according to the present invention is not limited to the above embodiment, and does not depart from the spirit of the present invention. Of course, various changes in the range are possible.

  For example, in the above example, the quadrangular column is a regular quadrangular column with four side plates having the same width and a square horizontal section, but a square column having a rectangular horizontal section is also possible.

  In the above example, the bottom closed portion is an auto bottom. However, any other type such as a plug-in type or a semi-auto lock bottom type may be used.
