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 eff

Embodiment Construction

[0012] Refer to attached figure 1 , this kind of hollow heat-insulating paper cup is composed of an inner cup 41 and a jacket 42 that are nested together. The upper mouth of the jacket 42 is rolled inward to form a circle to form an inner roll mouth 43, and the lower mouth of the jacket 42 is rolled inward. Form the inner rolling bottom 45 in a circle, and of course also fold the bottom inwardly to form the inner rolling bottom. After the outer cover 42 with the inner rolling bottom 45 and the inner rolling mouth 43 is combined with the inner cup 41, the outer cover 42 and the inner cup 41 cup wall There is a suitable hollow gap 44 from top to bottom, so the heat insulation effect of this kind of paper cup is very good.

[0013] Refer to attached figure 2 , 3 4. This kind of paper cup forming machine includes front and rear bases 1 and 14, and the front base 1 is equipped with a suction jacket paper sheet mechanism 2, a paper feeding mechanism 3, a jacket barrel bonding mec...

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...
