Hollow heat insulation paper cup and paper cup molding machine for manufacturing same

Abstract

The invention discloses a hollow heat insulation paper cup. The paper consists of an outer sleeve and an inner cup which is sleeved into the outer sleeve and is characterized in that: the upper opening of the outer sleeve is inwards turned to form an involute opening; the lower opening of the outer sleeve is inwards turned to form an involute bottom; and a hollow gap is formed between the outer sleeve and the wall of the inner cup. The paper cup has a good heat insulation effect. Simultaneously, the invention also discloses a paper cup molding machine for manufacturing the paper cup.

Description

【Technical field】 [0001] The invention relates to a paper cup and equipment for producing the paper cup. 【Background technique】 [0002] Paper cups have the advantages of convenience and hygiene, which bring great convenience to our daily life. Paper cups include ordinary single-layer paper cups and double-layer anti-scald paper cups, and double-layer anti-scald paper cups include corrugated heat-insulated paper cups and hollow heat-insulated paper cups. Existing paper cups with a hollow heat-insulating jacket are composed of an inner cup and a jacket. The jacket that acts as a heat-insulator only has its lower mouth rolled inward, while the upper mouth of the jacket and the inner cup are rolled outward together to form the mouth of the paper cup. Because there is no gap between the top of the jacket and the inner cup of the paper cup, only the lower mouth is separated from the wall of the inner cup, so the hollow gap between the outer jacket and the inner cup is tapered an...

Problems solved by technology

Existing paper cups with a hollow heat-insulating jacket are composed of an inner cup and a jacket. The jacket that acts as a heat-insulator only has its lower mouth rolled inward, while the upper mouth of the jacket and the inner cup are rolled outward together to form the mouth of the paper cup. Because there is no gap between the top of the jacket and the inner cup of the paper cup, only the lower mouth is separated from the wall of the inner cup, so the hollow gap between the outer jacket and the inner cup is tapered and heat-insulating. The effect is not good, especially in the upper part of the cup body, it basically does not have the effect of heat insulation and anti-scalding

At present, the equipment for making the above-mentioned paper cups firstly needs to finish the outer cover on one piece of equipment, and then put the outer cover on the ordinary single-layer paper cup forming machine to be socketed and rolled together with the inner cup, so that ordinary paper cups are formed The machine needs to increase the work plate and other auxiliary mechanisms, the structure is complex, and the most important thing is that the production of the above-mentioned hollow heat-insulated paper cups must be equipped with two equipment at the same time, which is inconvenient and expensive.
