This document discloses a disposable beverage cup with a non-removable straw. This disposable beverage cup and non-removable straw substantially reduce, or even eliminate, a chance that the straw will end up, on its own, polluting the world's oceans or land. This is due to the straw being non-removable and, along with the disposable beverage cup, being more likely to be properly disposed of, composted, or otherwise responsibly handled.

A coated paperboard container includes a paperboard substrate and an aqueous barrier coating on the paperboard substrate. The coated paperboard container has a repulpability yield of 75% accepts or greater, a sidewall seam bond strength of 30 pounds per inch or greater, and a wet rigidity loss of 50% or less.

A cone-shaped edible container according to the present invention comprises: an edible outer layer; an edible inner layer; a first edible adhesive layer disposed between the outer layer and the inner layer to bond the outer layer and the inner layer together; and a second adhesive layer for maintaining the outer layer and the inner layer to be in the shape of a cone, wherein at least some regions of the edible container have a first cross-section structure in which the inner layer, the first adhesive layer, and the outer layer are sequentially laminated in a direction from the inside toward the outside, and have a second cross-section structure in which the inner layer, the first adhesive layer, the outer layer, the second adhesive layer, the inner layer, the first adhesive layer, and the outer layer are sequentially laminated in the direction from the inside toward the outside.

A method of manufacturing a coated paperboard container includes: providing a coated paperboard bottom blank, the coated paperboard bottom blank comprising a paperboard substrate and a first barrier coating layer on a first outermost surface of the paperboard substrate; heating the coated paperboard bottom blank; shaping the heated coated paperboard bottom blank, thereby forming a peripheral skirt portion about a periphery of a bottom wall portion of the coated paperboard bottom blank; and sealing a coated paperboard sidewall to the first barrier coating layer of the peripheral skirt portion.

A cupstock for making rimmed cups, such as coffee cups, can be manufactured from recycled paper fibers while having a rim-formation index (RFI) and/or structural and flexural factors, based on certain properties of the cupstock to facilitate a quality rim. For example, the RFI can be based on the thickness, ring crush MD, bending stiffness MD, and areal density of the cupstock. The cupstock can be made from 100% recycled fibers from old corrugated cardboard (OCC) and provided with structural and flexural factors within respective ranges to ensure adequate rim formation when converted into a rimmed cup.

A cone-shaped edible container according to the present invention comprises: an edible outer shell, an edible inner shell, and an edible first adhesive layer provided between the outer shell and the inner shell to adhere the outer shell and the inner shell to each other. The outer shell and the inner shell are rolled into a cone shape in a state of being adhered to each other so as to have a basic structure of a cone shape. The outer shell forms the outermost side of the basic structure, and the inner shell has a stronger rigidity than the outer shell. Thus, assuming a cone-shaped structure implemented only by the outer shell, even if an external force of a magnitude capable of breaking the assumed structure is applied to the basic structure, the basic structure is maintained.
