Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a foldable paperboard cup, in which a rectangular cut board made by cutting the paperboard is stamped on both sides in the longitudinal direction and an intermediate base board, and a fold is made at the center of the baseboard. Stamping, stamping both ends of the crease in the center to the fold that is opposite to the two lines, and further pressing the fold along the above fold and pasting the edges of the fold. Foldable paperboard cups.

[0002]

[Prior art]

 FIG. 11 shows an example of a conventional paperboard cup. This paperboard cup has the same shape as a glass scoop and a round bottom. FIG. 12 shows another conventional paperboard cup. This paperboard cup has a structure in which folds of cut paperboard are attached.

[0003]

[Problems to be solved by the device]

 Although the paperboard cup shown in Fig. 11 can be placed on the table when not in use, it has a fixed shape and cannot be folded, so it occupies a relatively large volume and is inconvenient to carry when going out. Is. The paperboard cup of FIG. 12 can be folded to reduce its occupied volume when not in use. However, since the bottom is pasted together, it is difficult for the user to drink all the liquid in the paperboard cup, and it cannot be placed on the table and must be held by hand. No, it is inconvenient.

Therefore, an object of the present invention is to provide a foldable paperboard cup that solves the above problems.

[0005]

According to a first aspect of the present invention, a paperboard is stamped on upper and lower side plates and a base plate located in the middle of the side plates, and appropriate points on both long sides of the paperboard are bisected. In addition to stamping the creases, stamp a single fold line in the center of the foundation plate, and make a two-line arc-shaped fold starting from the point where the single fold line and the double fold line are connected to the base plate part. The eyes are stamped so that the angle between the two ends of the two-fold arc fold is 90 degrees, and at the same time, the distance between the middle points of the two-fold arc fold is exactly the diameter of the bottom of the cup. To fold, first apply viscose to the outer areas on the outside of the folds on both sides, then apply the viscose to the outer areas on the outer periphery of the folds of the base plate, and then in the prescribed order. Fold it in, and the viscose The painted areas are pasted together to complete a paperboard cup with a circular cup bottom.

[0006]

[Embodiment of device]

 FIG. 1 is an exploded view of the folding paperboard cup of the present invention. 4 and 5 explain the folding, and FIG. 6 shows the state when it is used. As shown in FIG. 1, the paperboard 1 is stamped on the upper and lower both side plates 11 and 12 and the base plate 13 located in the middle of the both side plates 11 and 12, and then at appropriate points on both long sides of the paperboard 1. Are stamped on the two fold lines 14 and 15. The distance between the two folds 14 and 15 is half the edge of the paperboard cup. A straight fold line 131 is stamped in the center of the base plate 13. This straight fold 131 divides the paperboard 1 into two equal halves.

Next, starting from the point where the one-fold fold 131 and the two-fold folds 14 and 15 are connected, two relative folds 132 and 133 are stamped on the base plate 13 portion. The two folds 132 and 133 have any suitable shape, and the part of the base plate 13 is folded along the two folds 132 and 133 to form differently shaped cup bottoms.

In order to make the explanation easy to understand, a paper cup having a cylindrical shape by folding the bottom of the cup will be described as an example. As shown in FIG. 1, starting from the point where the central fold 131 of the base plate 13 and the folds 14 and 15 on both sides are connected, the two arcuate folds 132 and 133 are stamped. The angle between the two end points of the two arc-shaped folds 132 and 133 is 90 degrees. At the same time, the distance between the midpoints of the bifurcated arcuate folds 132, 133 is exactly the diameter of the bottom of the cup.

Further, as shown in FIG. 2, the paperboard 1 is stamped on the folds 14 and 15 and the folds 132 and 133 by a model, and then, first, the outer section 16 and the foundation outside the folds 14 and 15 are formed. Viscose is applied to the outer peripheral area 17 on the outer periphery of the folds 132 and 133 of the plate 13. Next, as shown in FIG. 3, the paperboard 1 is turned over to apply viscose to the outer area 18 on the outer side of the opposing fold lines 14 and 15 in the portion of the base plate 13. Next, as shown in FIG. 4, first, the paperboard 1 is folded downward along the folds 131, and the viscose of the outer area 18 outside the folds 14 and 15 on both sides thereof is attached. Next, as shown in FIG. 5, both side plates 11 and 12 are folded upward along both upper and lower sides of the base plate 13 to form an outer area 16 on which upper and lower side plates 11 and 12 are painted with viscose. , The peripheral area 17 of the base plate 13 on which the viscose is applied, and the outer areas 16 of the side plates 11 and 12 on which the viscose is applied. After this, when the viscose dries, the foldable paperboard cup of the present invention is completed.

When using a foldable paperboard cup, the bottom portions of both side plates 11 and 12 of the paperboard 1 are pulled outward. Then, the bottoms of both side plates 11 and 12 are opened by the folds 132 and 133 of the base plate 13, so that the base plate 13 forms a bottom like an orange peel. At the same time, the side plates 11 and 12 are curved to form a cylindrical cup as shown in FIG. As shown in FIG. 6, the cup is filled with liquid and is then drunk. As shown in Fig. 7, the bottom surface has a hollow in the center and both ends are lifted up to look like an orange peel. Due to the bottom surface having such a shape, a hollow area 19 is formed between the inner edges of the side plates 11 and 12.

In addition to the above folding method, there is another method shown in FIG. First, the center of the two fold arc-shaped folds 132 and 133 on the foundation plate 13 is pressed downward. As a result, first, the inner regions of the two-striped arc-shaped folds 132 and 133 on the base plate 13 are depressed at the center and both ends are lifted up to become like a mandarin orange peel. Next, the paperboard 1 is folded and the areas 16, 17, and 18 of the paperboard 1 are painted with viscose and attached to each other to be fixed. When the viscose dries, a cylindrical paper cup is completed. After that, the fold line 131 at the center point is pushed upward to hold the paper cup flat.

The paper cup completed by this folding method has already been pressed in the same manner as a mandarin peel from the front when the two arcuate folds 132 and 133 on the base plate 13 are folded. Therefore, when using a paper cup, if you apply a slight force from both sides of the bottom of the cup and press it down, the base plate 13 automatically opens and becomes a bottom like an orange peel. Therefore, the lower side of the paper cup is opened more easily than the folding method shown in FIGS. 4 and 5 to form the bottom of the cup.

In addition, if the outer areas 16 of the two fold folds 14 and 15 coated with viscose are attached to each other by a method of overlapping each other, after completion, as shown in FIG. It is smooth and has no convex edges, resulting in an aesthetically pleasing cup.

[Effect of device]

 As described above, the foldable paperboard cup of the present invention can be folded to reduce the occupied volume when not in use. Moreover, when used, the bottom surface is circular, so it can be placed upright on the table without the inconvenience of having to hold it in the hand all the time. You can drink the whole liquid without leaving any liquid on the bottom.
