Benefits of technology

This patent describes a new type of coreless roll paper that can be compressed, which reduces the amount of space needed for storage and transportation. The rolls can also be separated from each other and individually sealed. This new type of paper can increase the amount of tissue that can be loaded into a trailer, increasing efficiency in delivering the finished product. The patent also discusses the challenges faced in achieving desired roll diameters when reducing sheet count and caliper, and how compressed rolls can eliminate these challenges. Overall, the patent presents a way to create a more cost-effective and efficient papermaking and converting process.

Problems solved by technology

Conventional hollow coreless products are also difficult to re-shape after compression to a stable “round” shape.

Embodiment Construction

[0049]The invention is described in detail below in connection with the various Figures for purposes of illustration, only. The invention is defined in the appended claims. Terminology used throughout the specification and claims herein are given their ordinary meanings as supplemented immediately below.

[0050]When we refer to the axial cavity of the product as “substantially collapsed”, the reference is to a flattened form as shown in FIG. 1A. Preferably, the gap between opposing sides of the cavity in the substantially collapsed configuration is less than 25 mm, preferably less than 10 mm, more preferably less than 5 mm and still more preferably less than 2 mm on average. In a preferred embodiment, opposing sides of the collapsed cavity are in contact over a major portion of their area, preferably over at least about 60%, more preferably over at least about 70%, even more preferably over at least about 80%, and most preferably at least about 90%, when rolls are in the compressed st...

Abstract

A compressed hollow coreless roll of absorbent paper sheet produced by way of providing a roll of absorbent paper sheet by winding the sheet about a forming core member having a diameter in the range of 30 mm to 50 mm; removing the forming core member such that there is provided a hollow coreless roll of absorbent paper sheet with an axial cavity having a diameter in the range of 30 mm to 50 mm and compressing the hollow coreless roll such that the axial cavity is substantially collapsed. The compressed hollow coreless rolls are readily re-formed into cylindrical shape. Space-saving packages of the rolls are overwrapped with tubular polymer film to provide a flexible reconfigurable package of a series of individually encased rolls. Volume reductions of about 10 to about 20%, about 14% to about 20%, 30%, 40% and more as compared with conventional products are realized.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is based on U.S. Provisional Patent Application No. 62 / 080,822, filed Nov. 17, 2014, which is incorporated by reference in its entirety.TECHNICAL FIELD[0002]The present invention relates to roll products and, in a preferred embodiment, to compressed and hollow coreless rolls of absorbent paper products such as tissue and toweling, commonly referred to as tissue, in flexible packaging that enables the manufacturer to ship a larger usable area of tissue in a given volume while enabling the end user to store tissue in nooks and crannies that might not be suitable for tissue packaged in conventional configurations.BACKGROUND[0003]Transportation costs add substantially to the cost of absorbent paper products sold for consumer use as the volume of these products is such that when the entire allowable space in a trailer or container is filled with product, the weight is typically far less than the load carrying capacity of the tr...
