Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a packaging container made of tiered sheets that is used to cover both the top and bottom of a package during packing.

(Prior Art) Conventional cover-type packaging containers made of corrugated sheets consist of a single corrugated sheet with folds and slits, and when folded into the container shape, it is held in place using adhesive tape or the like.

By the way, in the case of such a one-piece item, a standard size is required for each baggage, and it is uneconomical in terms of production as many types of molds have to be made. Furthermore, the work of fixing each fold with tape or the like is troublesome, and the appearance after assembly is also poor.

(Problems to be solved by the invention) This invention was made in view of the conventional situation, and by combining three elements: a support sheet of arbitrary length and gable sheets at both ends, This solves the above inconvenience.

[Structure of the invention] The following will be explained with reference to the embodiments of the drawings. In Fig. 1, numeral 1 denotes a patch sheet of arbitrary length in which an eaves sheet 2 of a predetermined width is formed on both sides in the longitudinal direction through folds 3. , 4, 4 are gable sheets 4, 4 integrally joined to the inner surfaces of both front and rear ends thereof.

That is, as shown in the same figure and FIG. Punch holes 5, 5 are provided in the glue margin 4a along the fold line 9. Further, a slit 6 is provided on the extension line of the fold line 3 of the eaves sheet 2 of the gable sheet 4, and a sleeve sheet portion 4b is formed on both sides and a folded portion 4c is formed in the center portion, and the folded portion 4c is formed in the middle. A fold line 7 that is folded inwardly into two is formed on the holder, and a fitting tongue piece 4d corresponding to the punched holes 5, 5 is provided at the tip.
has been formed.

Then, as shown in FIG. 3, the eaves sheet 2
With the folding of the gable sheet 4, the folded portion 4c of the gable sheet 4 is folded inward so as to sandwich the sleeve sheet portion 4b which is bent inwardly at right angles to the sleeve sheet portion 4b.
This is a corrugated sheet packaging container constructed by fitting the above-mentioned punched sheet into the punched hole 5.

Among the above, if the intermediate fold 7 of the folded part 4c of the gable sheet 4 is formed with two narrow folds 7a and 7b, a flat surface 8 can be formed at the boundary after folding. can.

(How to use) The multi-layered sheet packaging container having the above structure is used in the same manner as the conventional one, as shown in FIG.

[Effects of the invention] As described above, the invention provides the following effects compared to conventional packaging containers.

First, in the manufacturing stage, since it consists of three elements: the backing sheet 1 and the front and rear gable sheets 4, 4, by arbitrarily selecting the length of the backing sheet 1, you can freely create a packaging container that corresponds to each standard size of luggage. can get. In other words, there is no need to prepare production molds for each standard, and only a uniform mold for the gable sheet 4 is required.
This results in significant savings in production costs.

Further, since the folding is fixed by fitting the fitting tongue piece 4d into the punched hole 5, there is no need for a fastening means such as tape, which not only saves time but also costs. Furthermore, the appearance after packaging is also excellent.

Further, since the gable portion is triple-folded and the end portion of the eave sheet is also made double by the glue margin 4a, the corner portion is strong and impact resistance can be maintained. This also eliminates the so-called looseness at the corners, making the package fit and look very good.

Claims (1)

[Claims for Utility Model Registration] 1. A backing sheet 1 of arbitrary length in which eave sagging sheets 2 of a predetermined width are formed on both sides in the longitudinal direction through folds 3, and integrated with a slight glue allowance 4a on the inner surfaces of both front and rear ends thereof. The gable sheet 4 has a fold 9 formed inside with the edge of the backing sheet 1 as a border, and the glue margin 4a along the fold line 9. Punch holes 5, 5 are provided in the gable sheet 4, and a slit 6 is provided on the extension line of the fold line 3 of the eave sheet 2 of the gable sheet 4 to form a sleeve sheet portion 4b on both sides and a folded portion 4c in the center portion. Furthermore, the folded part 4c forms a fold line 7 which is folded inwardly in the middle, and the punched hole 5,
A folded portion 4c of the gable sheet 4 is formed so as to sandwich the sleeve sheet portion 4b which is bent inwardly at right angles to the eaves sheet 2 as the eave sheet 2 is bent. The structure of the corrugated sheet packaging container is made by folding the tongue pieces 4d inward and fitting the tongue pieces 4d into the punch holes 5. 2. A request for registration of a utility model in which the middle fold line 7 of the folded part 4c of the gable sheet 4 is formed by two narrow fold lines 7a and 7b so that the boundary after folding forms a flat surface 8. The structure of the corrugated sheet packaging container described in scope 1.
