Interleaved Transparent Cellulose Paper with Opaque Adhesive

Abstract

A method for applying adhesive to highly transparent cellulose rolling paper for a smoking article is provided, comprising the steps of holding the cellulose sheet under tension, applying a cellulose-based adhesive to a selected edge of the cellulose sheet, and drying the cellulose-based adhesive onto the cellulose sheet. The cellulose adhesive is comprised of water, cellulose gum and optionally, flavoring. The step of drying can be performed by air drying or drying with a shielded heat source. In one embodiment, a plurality of the cellulose sheets are assembled into an interleaved stack and enclosed in a suitable package. Optionally, the package containing the papers includes a magnetic closure and a tamper-resistant seal.

Description

BACKGROUND OF THE INVENTION[0001]I. Field of the Invention[0002]The present invention relates generally to an interleaved cellulose paper of high transparency having a line of opaque adhesive along an edge to wrap smoking materials.[0003]II. Background and Prior Art[0004]Materials or papers used for rolling smoking articles, such as cigars or cigarettes, may be made from a variety of materials such as reconstituted tobacco and paper. Typically such papers or “leaves” absorb saliva or have an edge coated with adhesive for sealing the rolled smoking article. Another product utilizes highly transparent cellulose paper, which can be made from cellulose of wood, cotton, or hemp that is blended with glycerin or a glycerin alternative, and water. Such cellulose paper, hereinafter interchangeably used with term cellophane, is appealing because it has no taste or odor, is highly transparent, and it allows a slower combustion without changing the characteristics of the smoking materials.

Benefits of technology

[0011]It is also an object of the present invention to provide a means for applying an adhesive to the cellophane and allowing it to dry without distorting the shape of the wrapping paper.

[0012]It is also an object of the present invention to provide a cellulose wrapping paper with adhesive that can be readily detected by the consumer.

[0013]It is a further object of the present invention to provide an adhesive that remains on the nonabsorbent cellulose paper, facilitating the utilization of an interleaved stack.

[0014]Accordingly, a method for applying adhesive to transparent cellulose wrapping paper is provided comprising the steps of holding a cellulose sheet taut, applying a cellulose adhesive to the cellulose sheet, and drying the cellulose sheet with cellulose adhesive. In order to prevent the adhesive from running off of the cellulose sheet, a cellulose based adhesive is used. In one embodiment, the adhesive comprises water, cellulose gum, and flavoring. The step of drying is performed with a shielded heat source. In another embodiment the step of drying is performed by allowing the sheets to air dry. The cellulose based adhesive further facilitates the interleaving of the sheets so they can be placed in a suitable enclosure and conveniently removed individually.

Problems solved by technology

However, the transparent cellulose wrapping papers that are currently available do not adequately adhere to themselves when rolled for smoking purposes.

A further limitation is that cellophane is water-resistant and is not capable of absorbing liquids.

Furthermore, upon application the standard acacia gum commonly used with rolling materials simply runs off of the cellophane sheets, thus impairing the ability to impart a workable adhesive area to the rolling paper.

The characteristic of being non-absorbent further limits the type of packaging that can be utilized for a plurality of interleaved sheets.

In addition, another deficiency of the prior art is the inadequate closure of the package or box of papers.

The prior art packages fail to remain closed and with routine use they become worn, remaining open even more easily.

When carrying the pack of papers in a pocket or purse, the package tends to open allowing the papers to fall out and become damaged.

Furthermore, an open package exposes the other leaves to the elements, or it causes the pack to become crushed or deformed if it is quickly inserted into one's pocket.

In other words, the cover can become deformed if the smoker does not purposefully hold the pack closed during its insertion into a pocket or case.

These limitations tend to frustrate the purpose of wrapping materials, that is, to permit the smoker to individually roll cigarettes and other smoking articles with a sheet that firmly adheres when rolled, and to provide the consumer with a convenient pack that allows each transparent sheet to be easily dispensed in a rollable condition.

However, none of these references disclose a method for gumming a transparent cellophane wrapping paper or an adhesive suitable therefore.

Furthermore, applying such adhesive or gum causes the cellulose sheet to warp and the ends of the cellulose sheet to curl.

A further problem posed by adhesives and acacia gums is that they are also transparent in appearance.

As a result, the high transparency of the adhesive makes it difficult for the consumer to determine which edge of the transparent paper has adhesive applied and thus, which edge should be moistened to seal the roll of smoking materials.
