Description

FOLDABLE PAPER CUP "

The present invention relates to a foldable paper cup, which is made by folding a paper cup so that it can be used by being filled with liquid and folded when not in use and stored in a folded state. In use, Like bag-type paper cup which can stand still but can hold up a good grip and can be conveniently used and reduced in production cost.

In general, a foldable envelope-type paper cup is manufactured by using a paperboard formed by laminating a plurality of paper sheets, and is portable and easy to use outdoors or outdoors. Paper cups, conical paper cups, and paper cups with fixed fasteners, which are flatly folded, are mainly used for drinking beverages in public places.

A folded paper cup in a flat form is sealed on three sides in a straight line and the other side of the unsealed side is held by hand to pour the drink. When you open the entrance of a paper cup for pouring drinks, you must use both hands or blow air into the mouth to open the mouth. If the drink remains in the paper cup, it must be hand held or supported by an object Is required.

A conical paper cup is formed as a cone-shaped cone, which seals the vertex of the cone and pours the liquid while holding the vertex of the cone from the outside. Even if you do not open the door for drinking, the entrance is always open, so it is convenient to pour the beverage, but when the beverage remains in the paper cup, be sure to hold it by hand or place the vertex of the cone in a circular hole Drinks pour out. Since the conical paper cup is fixed in shape, it is not easy to carry.

An example of a paper cup in which a fixture is inserted is a form disclosed in Patent Document 1, in which a fixture is inserted into a conventional foldable paper cup to keep the paper cup in a stable shape so that the paper cup can stand up even when the drink is contained. As shown in Fig. Although the paper cup with such a fixture can be used stably, the process from the folding of the folded paper cup to the hexagonal shape, inserting the fixture and pouring the beverage, is complicated and takes a long time and the fixture must be separately manufactured, Since the paper cup and the fixing member must be stored together at all times, the storage space becomes large and the user has to use the paper cup and the fixing member at the same time.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the configuration and effect of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a developed view of a foldable envelope-type paper cup according to an embodiment of the present invention. The foldable envelope-type paper cup 10 has a bottom portion a of a right triangle and a bottom portion (2) consisting of one line segment from one vertex (a) of one side p to meet the extension line (1) of the vertical movement line of one side p of the regular triangle, (p) and the first and second sides (2) are formed as two sides. The first parallelogram thus formed is composed of one side p, one side 1-2, one side 1-3, and one side 1-4. Thereafter, a r 'side having the same length as one side p is formed on an extension line of one side p and a second parallelogram having r' side and 1-2 side 2 as two sides, . The second parallelogram formed in this way is composed of r 'sides, 2-2 sides (3), 2-3 sides (r' ') and 1-2 sides (2). In a similar manner, a q 'side having the same length as one side (p) is formed on an extension line from the r' side, and a third parallelogram having q sides and 2-2 sides (3 sides) . The third parallelogram formed in this manner consists of q 'sides, the 3-2 sides (4), the 3-3 sides (q' ') and the 2-2 sides (3). (F-1, f-2) of the remaining two sides of the triangle constituting the bottom surface which does not contact the first parallelogram, and the sides opposite to the sides 2-2 of the third parallelogram (3) (F-3) of the base plate 4, respectively. In the developed view, the sides (p) shared by the first parallelogram and the triangle forming the bottom surface (a), sides (2, 3) shared by neighboring parallelograms, and another vertex A diagonal line 5 of a first parallelogram formed at a point A and a diagonal line 6 of a second parallelogram formed at a point A where the sides p and r 'meet, The diagonal line 7 of the third parallelogram formed at the point (d) where the sides meet and the glued faces (f-1, f-2, f-3) form an outer fold line that folds outward. Then, the extension line (1) of the vertical movement line of one side (p) of the equilateral triangle and the side (q ') facing the q' side of the third parallelogram at the point (d) The waterline (8) forms an inward folding line that folds inward.
