Description

Heat with double side walls is preserved and the thermal insulation dixie cup

Technical field

The present invention relates to a kind of dixie cup, particularly the present invention relates to have the heat preservation and the heat-insulating dixie cup of double side walls, this structure through improvement is described in korean patent application KR-2000-56706 that applies for applicant of the present invention and Korean Utility Model Application KR-2000-27081.In the present invention, formation has quite high-capacity dixie cup, products such as its noodles (NOODLES WITHBEAN SAUCE) that are used to store instant noodle, have soy sauce, wheat noodles, fried chicken are preserved and heat-insulating purpose for heat, and this dixie cup has double side walls, its manufacturing process is simple, save cost, can also obtain the finished product of aesthetic appearance, particularly, when a dixie cup was stacked on another dixie cup, these dixie cups were easy to be separated from each other.

Background technology

At present, dixie cup is considered to the necessity of daily life.Because daily life style links mutually with instant food, therefore, has developed multiple dixie cup.In other words, dixie cup is the important substitute of synthetical resin products, and described synthetical resin products is plastics, polystyrene foam or analogue for example.For example, recommend widely in the prior art to adopt dixie cup to replace the polystyrene foam cup, so that reduce environmental pollution.

Most of dixie cups have smaller volume, and it is suitable for holding food such as pure water, coffee, soft drink, also have the dixie cup of bigger volume so that hold food such as instant noodle, dessert, fried chicken, and this dixie cup worldwide is widely adopted.In this respect, the dixie cup with individual layer sidewall is used to store food such as pure water, coffee, soft drink, this content occupation ratio smaller volume.On the other hand, adopt dixie cup to store food such as instant noodle, dessert, fried chicken, these contents occupy bigger volume, and it needs thermal insulation structure, so that preserve the heat of content, meanwhile, allow user's grasping dixie cup experience a period of time.

For thermal insulation structure is provided, in the prior art, the professional has paid multiple effort, will describe the representative type example in detail below.

Heat is preserved and heat-insulating dixie cup is divided into three types substantially.In first type, dixie cup is provided with madial wall and lateral wall, (as Korean Utility Model Application KR-96-4519, name is called " heat is preserved and the structure of thermal insulation dixie cup " comprising being arranged on the thermal insulation paper with multiple shape between madial wall and the lateral wall; KR-96-22978, name is called " structure of heat preservation and thermal insulation dixie cup "; KR-99-25779, name is called " dixie cup that is embedded with the thermal insulation paper of embossment shape structure ").In second type, by on the dixie cup of madial wall and lateral wall, forming ridge and depression thing with thermal insulation usefulness, (for example constitute thermal insulation structure, Japanese Utility Model, publication number is the clear 50-88309 of JP-, name is called " heat is preserved cup ", and the clear 55-18346 of JP-, and name is called " dixie cup ").In the third type, can realize the combination of first kind and second type, form the ridge that along the circumferential direction is provided with at madial wall, so that between madial wall and lateral wall, form air space, the lower end of lateral wall is inwardly rolled, and be fixed on the madial wall part, they along the circumferential direction surround the cylindrical lip and the skirt section of diapire, therefore, obtain that actv. heat is preserved and thermal insulation structure (International Application PCT/JP99/5076 for example by the air space that forms, the applying date is on September 17th, 1999, the name be called " container; insulating vessel; and the equipment and the method that are used to make these containers "; And Korean Patent Publication No. KR-2000-142, name is called " equipment that is used to make the thermal insulation dixie cup ").

But the heat of these types is preserved and the thermal insulation dixie cup has defective described below.In first type dixie cup, must separately be arranged between madial wall and the lateral wall owing to have the thermal insulation paper of embossment structure, so that form three-decker, its manufacturing cost increases, and complicate fabrication process.In second type dixie cup, have the ridge of moulding and the thing that caves at madial wall and lateral wall, because these ridges and depression thing constitute thermal insulation usefulness, its complicate fabrication process is assembled performance and is reduced.And, on the outside face of lateral wall, be difficult to printed patterns, and the yield rate of final products reduces owing to have ridge and depression thing.

Simultaneously, describe the concrete structure of the thermal insulation dixie cup of the third type with reference to accompanying drawing 6, dixie cup 300 has madial wall 301, lateral wall 302 and diapire (no code name).On madial wall 301, form the ridge 304 that along the circumferential direction is provided with, so that between madial wall 301 and lateral wall 302, form air space.Also have, on madial wall 301, be provided with positive usual amounts indicatrix 303.The lower end of lateral wall 302 inwardly rolls, and lateral wall 302 lower ends are fixed to madial wall 301 parts, and they along the circumferential direction surround the cylindrical lip and the skirt section of diapire.Therefore, owing between madial wall 301 and lateral wall 302, form air space, have heat effectively and preserve and the thermal insulation function.The advantage that the thermal insulation dixie cup of the third type has is to have improved the assembling performance, and lateral wall has flat outer surface, and does not have ridge and depression thing, therefore is adapted at the outside face printed patterns of lateral wall 302, and the defective of its existence simultaneously is as described below.That is to say,, between the lower end of madial wall 301 and lateral wall 302, form at interval because lateral wall 302 lower ends inwardly roll.Particularly, in quantity is tens one of dixie cup when being stacked on another, distributes dixie cup in this state, the packing chest of after finishing processing dixie cup being packed into, this moment, the flange that respectively forms that becomes buffer action subsided downwards because the lower end of lateral wall inwardly rolls.So this class dixie cup is not easy to be separated from each other.Therefore, such dixie cup inconvenience is used for automatic vending machine, and a dixie cup that is stacked on another must be separated from each other easily in automatic vending machine.In addition, temperature booster separately need be set,, need to carry out the additional course of processing because equipment pumps for the lower end of the lateral wall that inwardly rolls.Because this fact, physical construction is huge and complicated, and manufacturing cost not only can not reduce on the contrary and increase.

At the korean patent application KR-2000-56706 and the Korean Utility Model Application KR-2000-27081 of the applicant application, name is called in " heat with double side walls is preserved and the thermal insulation dixie cup " and also exists above-mentioned defective.With reference to attached Figure 4 and 5, dixie cup has madial wall 101, lateral wall 106 and diapire 104 in this respect.Adopt conventional method cutting paper, make madial wall 101 have the profile of expansion, madial wall is rolled the profile that forms frustoconical, then, in the both sides of paper coating thermoplastic resin coating, thus moulding madial wall 101.At this moment, at the positive usual amounts indicatrix 102 of the top of madial wall 101 moulding, lower part at madial wall 101 is provided with ridge 103 along circumference, ridge 103 is protruding by this way, madial wall and lateral wall are spaced from each other, therefore between madial wall 101 and lateral wall 106, form air space 109.Madial wall 101 along the circumferential direction surrounds the cylindrical lip and the skirt section of diapire 104, and the lower end of madial wall 101 is folding at the free end in lip and skirt section, therefore lip is clamped in madial wall 101 partial sums by between the bonding part of adhesives, so that form container.The upper end of madial wall 101 outwards rolls makes flange 105, thereby makes the cup-like shape profile.Therefore, by this way, lateral wall 106 is installed around madial wall, and promptly the bonding madial wall 101 of adhesives is passed through in 106 upper ends of lateral wall, thereby constitutes double-wall structure.Form to cooperate step 107 on madial wall 101, inwardly therefore compacting can be seated at another dixie cup of stacking on this dixie cup and cooperate on the step 107 just in time above the disc-shaped base of diapire 104 by this way.And as clearly shown in Figure 5, the first half of the lip of diapire 104 or skirt section and madial wall 101 part combinations is shaped to the shape of compiling, lip and skirt section that diapire 104 in madial wall 101 part clampings.Therefore constitute the lean-in oblique angle, and the latter half 108 deflections of bound fraction, so that form the lean-out oblique angle.Consequently, because the ridge 103 that along the circumferential direction is provided with between madial wall 101 and lateral wall 106 forms air space 109 thus, thereby can obtain effective underground heat preservation and thermal insulation effect.And, owing to have the latter half 108 outside deflections of bound fraction, when lateral wall 106 is installed around madial wall 101, not only can form actv. air space 109, and improve face shaping.And can reduce production costs, for the user provides convenience, this dixie cup can be used for vending equipment, and in this vending equipment, one of dixie cup is stacked on another, and it must be easy to be separated from each other, so that drop on the cup support plate.

Meanwhile, preserve and the thermal insulation dixie cup for the heat with double side walls that constitutes above, it provides and has been superior to the advantage with conventional dixie cup of double side walls noted earlier, but this dixie cup still has shortcoming described below.Because lateral wall 106 is installed around madial wall 101 with this state, wherein the latter half 108 of bound fraction forms deflection, so that form outward-dipping angle, if lateral wall 106 is not accurately highly, the lower end of madial wall 101 and lateral wall 106 and upper end can not be suitable cooperatively interact, thereby between madial wall 101 and lateral wall 106, form abnormal error, and the profile of dixie cup is caused harmful effect.Also have, in this case, form the gap between madial wall 101 and lateral wall 106, the double-wall structure of dixie cup is weakened in the lower part of dixie cup, so inconvenient grasping dixie cup, thereby thermal insulation effect is weakened.

Summary of the invention
