A paper cup of a dual structure according to one embodiment of the present invention comprises: an inner paper part having a plurality of diameter adjusting portions formed at predetermined angle intervals on one surface; a drink receiving part formed extending from one end of the inner paper part and bending formed into the inner portion of the inner paper part; and a drinking part formed at a boundary between the inner paper part and the drink receiving part and curled in a radially outward direction of the drink receiving part.

A dispensing package for holding and dispensing food products, such as yogurts, frozen confections, custards, and the like, and may comprise a unitary, one-piece package body preferably comprising wicking-resistant, polymer-coated paperboard material which is liquid impermeable. Non-coated paperboard may alternatively be employed. The package body includes a sidewall having a generally elongated, downwardly and inwardly tapering configuration, and can include a crimped bottom. The sidewall is inwardly deformable so that inward deformation urges product within the package upwardly through the open mouth of the package for dispensing the product. The package can alternatively be configured with a flat bottom, and include a horizontal, bottom flex panel to facilitate deformation of the package for dispensing product. This embodiment permits the package to be readily positioned in a standing, upright orientation during consumption so that product does not inadvertently flow from the package.

A heat-sealable paperboard structure including a paperboard substrate having a first major side and a second major side opposed from the first major side, a heat-sealable barrier coating on the first major side of the paperboard substrate, and a top coat positioned over the heat-sealable barrier coating, wherein the top coat forms a discontinuous layer over the heat-sealable barrier coating.

Disclosed is a base paper for eco-friendly paper cups and, more specifically, to a base paper for eco-friendly paper cups, which is eco-friendly by having recyclability and biodegradability while retaining water resistance, oil resistance, heat sealability, and block resistance required as a base paper for paper cups.

A cellulosic structure including a cellulosic substrate comprising a first major side and a second major side opposed from the first major side, an oil barrier layer on the second major side of the cellulosic substrate, and a water barrier layer on the second major side of the cellulosic substrate, wherein the oil barrier layer is positioned between the cellulosic substrate and the water barrier layer.

Disclosed is a method for manufacturing a base paper for eco-friendly paper cups and, more specifically, to a method for manufacturing a base paper for eco-friendly paper cups, the method enabling the manufacturing of a base paper for eco-friendly cups, which has excellent heat sealability, water resistance, and block resistance, facilitates recycling, and is biodegradable in nature.

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.
