Description

Double body paper cup for keeping warm and insulation {Doulbe body paper cup for keeping warm and insulation}

The present invention relates to a double-cylinder paper cup for thermal insulation and insulation, and in detail, it is an improvement plan for the applicant's prior application (Patent Application No. 2000-56706 and Utility Model Registration Application No. 2000-27081), The large-capacity paper cups used for containers such as jjajangmyeon, udon noodles, chicken, etc. in containers or highway rest areas are formed with a double-cylinder body for thermal insulation and insulation. At the same time, in particular, when the cup and the cup overlapped to make it easy to be made easy.

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 Insulating and Insulating Paper Cups, Utility Model Registration No. 96-22978,' The Structure of Insulating and Insulating Paper Cups', Utility Model Registration No. 99-25779, 'Paper Cups with Embossed Insulating Paper') And the inner cylinder and the outer cylinder itself to be insulated to achieve heat insulation (Japanese Open Utility Model Publication No. 50-88309 'Insulated Cup', Japanese Open Utility Model Publication 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, Sep. 17, 1999, Apparatus and Method for Manufacturing Containers, Insulated Containers and Containers thereof, Korean Patent Application Publication No. 2000-0000142 'Manufacturer of Heat-Insulating Paper Cups') 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.

In order to improve this, the patent application No. 2000-56706 and the utility model registration application No. 2000-27081 filed by the present applicant have rolled the cup base cut in a developed state by a method known in ordinary paper cups, and the resin of the joint portion is applied. The inner surface of the cylinder 101 is formed by heat-sealing the coating layer, but the upper side of the cylinder is formed with a quantitative display line 102, and on the lower side thereof, the space forming protrusion lines 103 are arranged in a layer to protrude outward, and the lower side is formed. Insert the underlay 104 into and roll the inner periphery of the lower end of the inner cylinder 101 into a container, and roll the outer periphery of the upper end to form the rim 105 to complete the cup, and then the outer cylinder on the outer side thereof. In the conventional double-cylindrical paper cup made of an integral double-cylinder by sandwiching the 106 and applying and bonding the upper-side coupling part with an adhesive, the inner-cylindrical body 101 is inserted into and adhered thereto. Is indented into the inner cylinder 101 around the base of the base 104 to form a laminated cup locking jaw 107, and the bottom circumference of the inner cylinder 101 to which the base 104 is attached is bonded at an outer inclined angle. When the outer cylinder body 106 is inserted by the lower bent portion 108 formed to be forged, a space portion 109 is formed between the outer cylinder body 106 fitted to the outside together with the space forming protrusions 103. Insulation and heat insulation can be made so that when the other cup is inserted into the inner side by the stacking cup engaging jaw 107, the lower end of the mating cup is caught, and the bottom circumference of the bottom adhesive portion of the lower side side to the outside When the outer cylinder is fitted, the gap is formed and a clean finish can be achieved.It is convenient to use and clean in appearance while reducing the production cost, and the door does not hang when applied to the vending machine. The fundamental solution to the problem was made.

However, this preliminary proposal has a significant improvement compared to the conventional double-cylinder paper cups, but has some drawbacks. That is, by forming the outer circumference of the bottom adhesive portion of the lower end of the inner cylinder to be inclined outwardly to fit the outer cylinder, when the height of the outer cylinder is not exactly matched, a layer is generated between the inner cylinder and the outer cylinder of the lower side The appearance becomes unsightly, and the play occurs and the lower double cylinder structure is inconvenient to catch, and the insulation effect is also lowered, resulting in a problem that is insufficient to fully realize the original purpose.

The present invention is an improved design to completely solve the problems raised in the preceding design, it is formed by dividing the middle around the base adhesive portion of the lower end of the inner cylinder to be spread out to the outside slope to form the other half around the bottom vertically Therefore, even if the height of the outer cylinder within the half-height range is tightly fitted, even if the height of the outer cylinder is kept tightly aligned even if the upper end from the inner cylinder curling portion to maintain a constant gap between the inner cylinder and the outer cylinder It is beautiful in appearance, and there is no play, so it can be used to hold and feel like a single cylinder even when held by hand, and the insulation effect is completely guaranteed.

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, wherein a quantitative display line 2 is formed to protrude from the upper side around the cylinder, and a space forming protrusion line is formed on the lower side thereof. 3) arranged in a layer to form a protruding outward, and insert the underlay (4) on the lower side and roll the inner periphery of the lower end of the inner cylinder (1) to form a container with the upper edge around the outer edge ( 5) After forming the cup to complete the cup by inserting the outer cylinder (6) on the outer side and the upper side coupling portion by applying an adhesive to form a double body of the integral, but inward to the inner lower portion of the inner cylinder (1) In order to form a laminated cup latching jaw (7) by the concave, the height of the lower fold portion of the inner cylinder (1) bonded to the underlay (4) is divided into two equally formed to open the upper circumference to the outer inclination angle Slope The outer cylinder 6 which forms the part 8a, and the lower side is formed by the vertical bending part 8b, and is fitted to the outer side with the said space forming protrusions 3 when the outer cylinder 6 is fitted is Stable and precisely sandwiched between the space (9) is formed to be configured to keep warm, heat insulation.

The present invention configured 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 a state in which the inner cylinder 1 is completed in the above-described structure. The stacking cup catching jaw 7 formed at the bottom 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 so that it can be manufactured without any additional process and the inner cylinder The bottom underlay adhesive part of (1) is divided in the middle, and the upper part is inclined outwardly to form an inclined extension part 8a, and the lower part is formed at the height of the vertical bent part 8b by forming a vertical bent part 8b. By holding the lower inner side of the outer cylinder 6 relatively broadly, even if the length of the outer cylinder 6 is rather short, it is possible to clean the exterior by fitting the lower end without being particular about it.

In this case, the height of the outer cylinder 6 is rather small so that the lower end is aligned so that the upper end of the outer cylinder 6 may be slightly spaced apart from the edge 5 formed by rolling the outer circumference of the inner cylinder upper side outward to fit the inner and outer cylinders. There is no possibility of harming aesthetics because it is not identified at all compared with the layer formed on the lower part of the trunk, and there is no fear of play because the lower side is firmly fitted, so it is easy to hold by hand and there is no fear of losing the warming effect. As a result, they have structural features that can fully realize the original intent and purpose by solving the inadequate parts that were not solved in the preceding design.

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 difficulty in general use as well as vending machine, so that the convenience of use can be greatly improved. The bottom adhesive portion of the inner cylinder is divided by dividing the upper portion to be inclined, and the lower side is formed vertically to serve to hold the inside of the lower portion of the outer cylinder fitted to the outside widely, even when the height of the outer cylinder is rather small. You can finish the exterior cleanly without any problem. It is easy to hold by hand because it is firmly fastened between the inner and outer cylinders, and it is useful to realize the original purpose of the double-cylinder paper cup to realize the insulation and insulation by greatly improving the insulation and insulation effect. It is.
