Description

Double body paper cup for warming and insulation {Double body paper cup for warming and insulation}

The present invention relates to a double-cylinder paper cup for thermal insulation and insulation, and in particular, a large-capacity paper cup used as a container such as jjajangmyeon, udon or chicken in a relatively large cup ramen container or highway rest area, etc. In forming, the structure is easy to manufacture, so that the appearance is beautiful with cost reduction and clean finish, and in particular, it is suitable to be easily separated when the cups are overlapped.

As is well known, paper cups are a necessity of modern life, along with the development of the fast food culture, various types of disposable products have been developed and used, and as a substitute for plastic or styropol synthetic resin products, As a result, cup noodles made of styropol are replaced by paper cups at the government level.

Paper cups range from small shochu cups to large-capacity containers for coffee, beverages, ramen cups, snacks and chicken, and a single body is usually used for coffee and beverages. However, in the case of using a large-capacity container such as a cup ramen container, a heat insulation structure that is easy to hold for a long time along with the insulation of the contents is required.

As a method for realizing this, a number of patents and utility models have been applied and registered at home and abroad.

There are two types of paper cups for thermal insulation and heat insulation. First, two kinds of inner cylinders and outer cylinders are molded, and various types of embossed insulation paper are inserted therebetween to insulate them (Utility Model Registration Application No. 96-4519). No., "The Structure of Insulation Paper Cups, Utility Model Registration Application No. 96-22978," The Structure of Insulation Paper Cups ", Utility Model Registration No. 99-25779," Paper Cups with Embossed Insulation Paper ") And the inner cylinder and the outer cylinder itself are uneven to achieve heat insulation (Japanese Utility Model Publication No. 50-88309 "Thermal Cup", Japanese Utility Model Publication No. 55-18346 "Paper Cup") In the form of a combination thereof, a protruding frame for forming a gap is formed in the inner cylinder, and the lower end of the outer cylinder is encapsulated and fitted inward so that a space is formed between the inner cylinder and the outer cylinder. To ensure that insulation is achieved (International application PCT / JP99 / 05076, filed September 17, 1999 "apparatus and method used in the manufacture of a container, a heat insulating container and its container", Korean Patent Publication No. 2000-0000142 "apparatus for manufacturing a heat insulating paper cup") And the like are known.

However, each of the preceding measures had insufficient drawbacks and problems. In the case of inserting the insulating paper between the first inner cylinder and the outer cylinder, the three separate layers of embossed separate insulating paper should be formed, thereby producing the cost. Not only increased, but also the manufacturing process is difficult, and the second printing process is complicated, poor assembly and poor external printing due to irregularities There was a defect that the cotton is poor and the merchandise deteriorates.

Compared to these, the third heat insulating cup 300 having a relatively improved structure forms a protruding frame 304 and a quantitative display line 303 for forming a gap in the inner cup 301, as shown in FIG. The lower end of the 302 is formed by fitting the curling portion to the inside to form a space between the inner cylinder and the outer cylinder to ensure insulation and heat insulation, the assembly is good, the outer surface of the outer cylinder is not uneven Although there is an advantage of being a smooth surface and the printing surface is clean, the lower side of the outer cylinder is curled inward so that there is a gap between the inner cylinder and the lower cylinder, and above all, the decisive problem is that the cup is usually When manufacturing and packing in box or distribution, dozens of cups and cups are overlapped to reduce volume and packed. There is a problem such that it does not fall well in the separation for use to eat, and in this case, it is not possible to apply to the vending machine because the separation is not made in the stacking to the vending machine to fall one by one. The separate heating heater according to the engraving operation of the lower side of the sieve and the molding process according to the up and down reciprocation are required separately, so that the mechanical configuration is enlarged and complicated, and manufacturing costs are increased.

The present invention has been made in view of the above-mentioned drawbacks, and by the method known in the conventional paper cups, the quantitative display lines and the space forming protrusions are arranged in a layered manner around the inner cylinder, and the bottom side is recessed inwardly. Forming a stacking cup jamming jaw to allow the other end of the cup to be caught when the other side of the inner cup is caught, and the bottom circumference of the bottom adhesive side of the bottom side to be folded outward to form a gap when the outer cylinder is fitted It is designed to achieve a clean finish, so that it is easy to use and clean in appearance while reducing production costs, and it can fundamentally solve the problem that it does not get stuck even when applied to a vending machine.

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

The cup base cut in the unfolded state is rolled into a cylinder to heat-bond the resin coating layer of the joint to form an inner cylinder 1, with a quantitative display line 2 formed on the upper side around the cylinder and a space forming protrusion line 3 on the lower side. ) To form a layer to protrude outwards, and to insert the underlay (4) on the lower side and to roll the inner periphery of the lower end of the inner cylinder (1) inward to form a container, the outer periphery of the upper end is rolled out (5) In the ordinary double-cylinder paper cup made of an integral double cylinder by inserting the outer cylinder 6 on the outer side and applying and bonding the upper coupling portion with an adhesive after forming the cup, the inner cylinder 1 Of the inner cylinder (1) to which the underlay (4) is inserted into the inner cylinder (1) around the adhesive portion to be laminated inwardly to form a laminated cup latching jaw (7), Bottom circumference at outer inclination angle The space 9 is formed between the outer cylinder 6 fitted to the outside along with the space forming protrusions 3 when the outer cylinder 6 is inserted by the lower bent portion 8 that is formed erratically. It will be configured to keep warm, insulation.

The present invention constituted as described above has good assembly ability in manufacturing because assembly is performed by simply pushing the outer cylinder 6 printed on the outer surface with a simple cylinder in the state in which the inner cylinder 1 is completed in the above-described structure. The stacking cup catching jaw 7 formed on the outer surface of (1) may be made at the same time as the process of forming the normal quantitative display line 2 and the space forming protruding line 3, and thus may be manufactured without any additional process and bent at the bottom. Since the part 8 is made together with the process of forming the underlay adhesive part, there is an advantage in that the process of encapsulating the lower part of the outer cylinder as described in the preceding design, and the size and complexity of the manufacturing apparatus, can be reduced. When sandwiched with each other, the laminated cup catching jaw 7 is formed to protrude inwardly at the lower side of the inner cylinder 1 so that the lower end of the cup to be fitted is caught, thereby preventing the cup and the cup from being caught. In addition, the cup to be fitted is also curled into the lower end of the outer cylinder 6 as in the prior art, so that the cup and the cup are firmly inserted into the lower bent portion 8 of the inner cylinder 1 without being caught in cushioning. It has structural features that can fundamentally solve the problem.

The present invention as described in detail above can be manufactured in addition to the existing process without the need to add a special process in manufacturing, compared to the double-cylinder paper cup of the existing structure, while significantly reducing the manufacturing cost and good assembly performance Beautiful appearance and above all solve the problem of cup and cup jamming fundamentally, it can be easily removed without being difficult for general use as well as vending machine, so that the convenience of use can be greatly improved. It has a useful effect.
