Description

Paper cup having a cap of itself}

The present invention relates to a paper cup having its own lid, and more particularly, to a paper cup having a plastic lid, which is frequently used in fast food restaurants, rest areas, etc., so as to be opened and closed by forming a lid on the cup body itself without the need for a plastic lid. will be.

As is well known, small-cap paper cups used for vending machines and other coffees are 6.5 oz. Lids are not used. However, beverage paper cups, which are used mainly in fast food restaurants or rest areas, are large-cap paper cups larger than 9 oz. You will be served a drink.

However, as the environmental hormone problem has recently emerged as a social problem, plastic containers have been legally formulated and the use of plastic products in food containers has been banned.

In the case of hygienic or when carrying a cup, etc., the lid is necessary, and a method for improving this has been attempted earlier.

In the case of the prior invention, as shown in Figures 3 and 4, when cutting the paper fabric for manufacturing the cup to cut the lid 12 protruding to the upper side of the cylinder 11, but higher than the center of the disc And the lower side of the disc is formed by pressing the folding line 13 so that the bottom side of the disc is folded inclined from the cylinder, and the lower side of the disc is folded from the bottom of the cup cylinder, and the protruding upper side is folded into the upper side of the cup to be covered. On the other hand, the remaining portion except for the lid portion around the upper end of the cup cylinder is attached to the plastic rim 14, and the locking jaw 15 is formed on the inner side of the rim so that when the lid 12 is folded and pressed, 15) to prevent the lid from coming back.

However, this prior invention has the advantage of not needing a separate lid, but by using the plastic frame 14, efforts to eliminate the plastic member in the paper cup was insufficient. Therefore, it is difficult to recycle because the plastic must be separated during recycling after use, there is a problem that does not rot when landfilling and polluting the air environment due to the generation of toxic gas during incineration, the inner locking jaw (15) of the plastic frame (14) As the entire circumference of the lid is hung, it is necessary to press the finger when drinking and pull out the lid, but it does not fall well, soaking the finger in the soaked beverage, there was a very inconvenient use.

The present invention has been devised to solve the above-mentioned drawbacks, the upper circumference of the cup cylinder is formed by curling the top of the cup cylinder to the outside like a normal paper cup to form a rim, the other half except for the part to form a lid Curling only the excess portion to form a rim, and the remaining uncurled portion is formed into a disc shape to protrude to the top to form the lid of the cup base itself, while the lid of the cup to be caught inside the top of the cup cylinder In order to make it possible to form two rows of protrusions into the inside of the cylinder, and by forming a handle on both sides of the lid to facilitate the opening of the lid at the same time the lid between the two rows of protrusions firmly The fitting action can be made, and the lid is closed so that it is easy to drink by using a straw. To form an incision in the "+" shaped side of the unit will do so as to facilitate inserting the sucking straws.

Hereinafter, the present invention according to the accompanying drawings and preferred embodiments in detail as follows.

To better understand, the paper cup manufacturing process is outlined, and the paper cup is coated with a thin vinyl coating on the outer surface of the rolled fabric to prevent leakage, and the outer surface is arranged for the cup cylindrical development. After forming the pattern by using offset printing), punch the cup base paper in the cup cylindrical development state by punching machine to make a cup in the paper cup forming machine, and in the paper cup forming machine by laminating the cut cup paper as described above one by one The primary cylindrical molding process of automatically supplying and adhering to a cylindrical shape, and attaching the underlay to the side of the paper cup forming machine with the vinyl coated base wound with a tape-shaped roll, forming a punch by punching while releasing and supplying it continuously. The process of inserting into the cup cylinder formed in the car body molding process It leads to the underlay heating bonding process.

In the underlay heating bonding process, the lower part of the cup cylinder with the underlay is usually preheated and preheated by the heater, and the upper end of the cup is curled to the outside in the second curling process and the lower end is bent inward. The process of curling up and down so as to wrap and wrap the lower bent portion of the underlay is carried out at the same time up and down.

At this time, the bottom of the mold to dry the inner side of the inside of the heat heater is built in the heat inside the bottom of the cup cylindrical body while heating the vinyl coating layer in a semi-melted state to be smoothly bonded in the next lottery bonding process To be able.

The cup cylinder, which has been sufficiently preheated by the lower side being rolled inward, is brought into the lottery bonding process, and the rotator ball which rotates and revolves in the state where the cup cylinder is fitted to the outside of the bottom of the cup cylinder, i.e., the underside is fitted. The lower periphery is pressed to complete the paper cup.

It is manufactured by such a series of manufacturing processes, and cut to form the cup base to be unfolded to form the cup base, and when forming the punching, the center upper part is formed into a disc shape, but the projecting height is 3/5 height of the whole disc protrudes And the lower side 2/5 is formed by pressing the folding line 3 along the disc so as to be the cup cylinder 1 itself so that the lid 2 can be folded, the upper end of the cup cylinder 1 Curling frame (4) is formed by curling the remaining portion except the perimeter lid (2) to the outside, and spaced around the upper side of the cup cylinder (1) in order not to be retracted when the lid (2) is closed A pair of protrusion lines 5 are formed to protrude to the inside of the cylinder, and handles 6 are formed on both sides of the lid 2 so as to easily open the closed lid 2, but the lid 2 is closed. Close the lid by pressing the folding line (7) along the outer line of the When folded to the upper side so as to be firmly sandwiched between the pair of protruding lines (5), while forming a '+' shaped incision (8) on the upper side of the lid by inserting a straw in the closed state drinking It is configured to facilitate.

The present invention configured as described above has a lid along the folding line (3) simply by pressing the lid (2), which is filled with the beverage, without the inconvenience of opening and closing a separate lid when providing a drink to a guest at a fast food restaurant or a highway rest area. While being folded, the lid 2 is closed between a pair of protruding lines 5 protruding inwardly around the upper side of the cup cylinder 1, so that the handle 6 protruding from both sides is also folded line 7. By being folded to the upper side by), this part has a double thickness compared to other parts, so that the lid is more firmly held on both sides, thereby maintaining a tightly closed state.

In addition, the '+' shaped incision (8) formed in the lid can easily drink the drink by inserting the straw even in the closed state of the lid (2), even if you drink in the state in which the lid (2) is opened according to taste The curling frame (4) formed by rolling the cup cylinder made of paper is wrapped around the upper end of the cup cylinder to soften the touch to the lips, so that it does not feel rough by the conventional plastic frame. (2) is easily pulled out and opened in a state where it is fitted in a pair of protruding lines (5), it is convenient to use.

As described above, the present invention is provided with a lid that is folded by itself without a plastic lid or a plastic rim, which is very convenient to use, and fundamentally solves the problem of using plastic in food containers which are prohibited from being used due to environmental hormones. It is possible to solve the problem, and recycle the pulp by recycling the entire paper cup as it is, and even when it is reclaimed or incinerated, it is useful to be able to greatly contribute to the environmental industry, such as minimizing environmental pollution. .
