DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in more detail with reference to the drawings.
FIG. 1 is a development view of a carton blank of a cover for a body carton according to the present invention.
As shown in FIG. 1, a carton blank 10 'for a cover carton cover according to the present invention has a substantially rectangular top plate 1 having outwardly bulging edges R that are substantially the same shape as the bottom plate 11 of the body. Are connected to a double fold line region 6 which is surrounded by a double fold line ab having a cross section of a convex lens, which is expanded at the center via a fold line a and closed at both ends, and four sheets are connected to the outside via a fold line b. The vertical side plates 2 and 3 are connected to each other, and both ends of a pair of opposing side plates 3 are extended to provide four vertical curved surface forming portions 4 'and four glue margins 5 in this order. is there. Note that the margin 5 is a portion that turns behind the side plate 2 during molding, and the upper edge (inner side in FIG. 1) of the margin 5 is punched in accordance with the arcuate upper side of the side plate 2.
In addition, when the cardboard blank 10 'as the cover lid is strong in rigidity and the bending resistance is large, it becomes difficult to form from the carton blank 10'. It is preferable to provide parallel weak lines (perforations, half-cut lines, etc.). When the board has low rigidity, it is not necessary to provide such a weak line. Further, regarding the double folded line ab, when the board has a high rigidity, it is preferable to use a so-called lead ruled line in which a half cut is added to a normal ruled line.
[0006]
FIG. 2 is a developed view of the carton blank of the body carton according to the present invention.
The body carton blank 20 'is assembled into a tray-like body, and various embodiments can be proposed.
FIG. 2 is a development view of one embodiment. In this case, the body carton blank 20 ′ is opposed to one of its four sides centering on a quadrangular bottom plate 11 having rounded corners. Two rectangular side plates 12 are connected to each other via a fold line, and two rectangular side plates 13 are connected to the remaining two sides via a fold line. A curved surface forming part 14 ′ and a margin 15 are provided in this order.
The upper sides of the side plates 12 and 13 of the body 20 of the lid carton 30 according to the present invention are structurally strong and feel to the top plate 1 of the cover 10 in fitting with the cover 10. It is preferable to contact, and it is stamped in the curve shape matched with the partial curved surface of the back surface of the top plate 1.
The vertical curved surface forming portion 14 ′ may be provided with a plurality of parallel weak lines (perforation, half cut, etc.) as shown in FIG.
The developed view of the carton blank 20 'is not limited to that shown in FIG. 2, but is any shape as long as the horizontal cross section is formed into a square tray shape with rounded corners at four corners. It may be. However, it is desirable to assemble from a single carton blank.
[0007]
FIG. 3 is a perspective view of a lid carton according to the present invention. FIG. 3A shows a fitted state of the lid carton 30, and FIG. 3B shows an opened state of the lid carton 30.
A body carton 30 according to the present invention comprises a cover 10 and a body 20 assembled from a carton blank 10 'shown in FIG. 1 and a carton blank 20' shown in FIG. 2, respectively. It is determined by 10 external shapes.
That is, the covering lid 10 of the body carton 30 according to the present invention has a quadrangular top plate 1 with rounded corners at four corners, four double fold line regions 6 connected to the four sides, and extending to them. It is a 13-sided body shape composed of four side plates 2 and 3 and four vertical curved surfaces 4 provided by extending both ends of the side plate 2.
It should be noted here that the double fold line region 6 is forcibly folded inward by the double fold lines a and b on the four sides of the top plate 1 to form a concave surface, so that all other surfaces are affected by this molding. In other words, the entire surface or part of the surface is slightly convex.
In other words, the entire top plate 1 is a convex surface whose center portion is gently lifted, and the four side plates 2 and 3 are also convex surfaces whose central upper portions are loose and bulge outward. The four vertical curved surfaces 4 are exactly convex surfaces themselves.
[0008]
Since the covering lid 10 made of the 13-sided body of the body carton 30 according to the present invention has all the surfaces curved to some extent, these curved surfaces can be seen from any angle. The angular feeling peculiar to the carton disappears completely, and it has a soft and unique advanced design and a high-class feeling.
In addition, since the pre-printing method with high degree of freedom for paperboard can be adopted, the synergistic effect of the graphic design by the form of the cover lid and printing can be demonstrated, and an unprecedented design and luxury can be created. . Therefore, it is effective as a package for small gifts such as candy and chocolate.
Candy, chocolate, etc. are primarily packaged and boxed in the crate carton 30 according to the present invention, but the outer side can be further overlapped with a heat-shrinkable film, stretch film, etc. It is preferable from the point of prevention of mischief.
[0009]
A wide range of paperboards such as ivory, card, manila, and coated ball can be used for the lid carton 30 according to the present invention, and both can be used in the range of 290 to 480 g / m ² . It is also possible to use a so-called “back-necked” court ball using recycled paper on the back side.
Moreover, you may use the paperboard which has a polyolefin-type resin layer in the single side | surface or both surfaces of a paperboard.
Furthermore, by providing an aluminum foil having a metallic luster or a glossy resin layer on the outer surface, a polyhedron having different glossiness can be obtained for each surface when viewed from one point, and the design can be further enhanced.
[0010]
A carton blank 10 'for a lid of a body carton according to the present invention is a preprint different from printing on a plastic molded article, etc. The degree of freedom is high, and any known printing means such as offset, gravure, flexo, and silk screen can be used.
Furthermore, surface processing after printing such as foil stamping, embossing, and labeling can be freely performed.
In addition, mechanical molding of the lid carton 30 according to the present invention from the carton blank is sufficiently possible by slightly modifying the conventional carton electing machine, and it is not necessary to newly design and manufacture the carton. Further, the conventional apparatus can be used as it is for the overlapping by shrink film or the like.
[0011]
The cover 10 and the body 20 of the cover carton 30 according to the present invention described above are coated balls (back white) 310 g / m ² (manufactured by Daishowa Paper Co., Ltd.), and the dimensions shown in FIGS. Each of the carton blanks 10 'and 20' having the assembly was manually assembled, and these were fitted to create an example sample of the lid carton 30 according to the present invention. Note that the glue margin 15 was glued only to the 6.3 mm portion at the tip.
The model consisting of the 14-hedron of the example sample has a unique and appealing effect, is excellent in design properties, and has a high-class feeling.
In addition, offset printing was used for preprinting, and varnish overprinting was applied to the entire surface.
[0012]
The lid carton 30 according to the present invention is not limited to the description of the above embodiments and drawings, and can be variously modified without departing from the gist of the present invention.
For example, the top plate 1 and the bottom plate 11 are not necessarily square. In addition, processing such as window pasting may be performed on a part of the top plate 1 to show the contents.
[0013]
【The invention's effect】
According to the body carton according to the present invention, the cheap and environmentally friendly material of paperboard is used to the minimum, and all the 13 surfaces of the cover lid 20 are formed of curved surfaces, making it unprecedented soft and unique. A gift package that can be shaped, has a stronger appealing effect, and has a higher degree of design and luxury.
Therefore, not only the effects of appealing and differentiating at the store, but also chocolate, candy, etc. can of course be used as a package for other general gifts, and satisfaction can be given to both the gift sender and receiver.
In addition, assembly does not require installation of a new carton electing machine, and can be assembled from a carton blank having a minimum required area.
Furthermore, it is possible to provide a package with a low environmental load that can be discarded after being returned to a flat blank state after use, and can be discarded.
