The present disclosure discloses a fresh-keeping paper box comprises a box body, and the box body is composed of a side wall spliced by a whole paperboard and a bottom wall formed by another trimmed paperboard; the bottom wall is pasted to the inner side wall of the side wall; an accommodating space for containing foods is formed inside the box body, and the accommodating space has an open upper end and a closed lower end, the technical scheme in this disclosure effectively solves the problem that airtightness of the existing paper box is influenced by joints inevitably occurred in its molding process, and the circumstance that multiple box bodies in overlaid packaging are difficult to separate due to airtightness is effectively prevented because of the bottom gap, thus makes it more convenient to use.

An apparatus for forming a box or bag that is made of a substrate strip which includes a winder having a mandrel and posts that extend from the mandrel in a direction parallel to a winding and translation axis that rotate together as a unit around the translation axis. The apparatus also has a feeder that includes precursors and a gathering head used for forming the precursors into the strip and feeding the strip to the winder. A motor adjusts the feeder's angle relative to the winder in response to instructions from the controller based on the dimensions of the box or bag. This causes controlled overlap between adjacent windings of the strip on the posts. As the mandrel rotates, the posts draw the strip and wind the strip along a spiral having a length in excess of the depth. Zero waste of precursors is made possible by cutting the substrate perpendicular to its length and folding over the box or bag ends to form an angled seam with respect to the sides of the box.

The present invention provides a container comprising a cup; a protective member attached to a side wall of the cup, the protective member including: an outer side wall portion; an inner side wall portion contacting the side wall of the cup; a bottom end portion connecting between a bottom end of the outer side wall portion and a bottom end of the inner side wall portion; and a top end portion connecting between a top end of the outer side wall portion and a top end of the inner side wall portion, the top end portion having at least one hole; and an air gap formed between a side wall of the cup and the protective member, wherein the at least hole allows air to flow between the air gap and outside.

The multi-layer recyclable cup is a container. The multi-layer recyclable cup is configured for use in storing a hot liquid. The hot liquid is adapted for consumption by a person. The multi-layer recyclable cup is an insulating structure that inhibits the hot liquid from decreasing in temperature while stored in the multi-layer recyclable cup. The multi-layer recyclable cup comprises a cup. The cup is formed from a composite material. The composite material is a fully recyclable structure.

A solution for a logistical problem within the beverage industry, specifically related to hot beverages such as coffee and tea; namely, storing the means to sell the beverages, which generally includes a cup, a lid for the cup, and an insulation sleeve that allows holding the cup in a comfortable way for the consumer, avoiding burns due to the high temperatures of the liquid. Thus, the container presented here unifies the 3 elements, comprising a body formed by a base and a wall, where the upper edge of said container has a group of flaps that in their closed position enables liquid containment and prevents spillage in case the container is moved, and through a modification in the cross profile of the wall. Additionally, the container has an insulation sleeve that keeps the contact surface at a low temperature.

Disclosed is a double-layer corrugated paper cup applicable to unmanned full-automatic manufacturing. The corrugated paper cup comprises a cup body formed by rolling a fan-shaped sheet, the fan-shaped sheet having a first straight edge and a second inclined edge, a first end of the single-layer corrugated paper is staggered with and parallel to a first end of the inner cup paper and a second end of the single-layer corrugated paper is flush with a second end of the inner cup paper, a corrugated cavity region of the fan-shaped sheet is flattened to form a first extruded corrugated cavity region and a thickness of the first extruded corrugated cavity region is smaller than that of a middle part of the fan-shaped sheet and a part of the first extruded corrugated cavity region is rolled outwardly together with the inner cup paper to form a rolled rim.
