Benefits of technology

[0009]The present invention provides packaging or containers for smokeless tobacco products and other consumer and food products. The containers include at least one wall structure in the body or top thereof that includes a barrier material that provides advantageous features, such as protection against environmental effects and moisture variability.

Problems solved by technology

For example, in humid environments, moisture may invade the storage space housing the product, thereby damaging the product or otherwise rendering the product unusable.
Alternatively, moisture within the product may escape the packaging leaving the product prematurely dry and difficult to dispense.
Further, current fiberboard cans have poor sealing attributes thereby posing a challenge to ensure fresh product for consumer use.
This wax coating is prone to stress cracking and therefore is not fully effective.

Abstract

Containers for smokeless tobacco products and other consumer and food products are provided. The containers include a layer of fibrous material, wherein the layer of fibrous material includes a moisture barrier layer imbedded within the layer of fibrous material or carried on an outer surface of the layer of fibrous material as a coating, the moisture barrier layer incorporating at least one of: (i) a triazine-containing compound; (ii) a nano-cellulose material; (iii) a nanoclay material; (iv) a polymer composition comprising one or more of a salt of one or more of myristic, palmitic and stearic acid, polyvinyl alcohol, and a C9-C18 fatty acid complex of a metal ion having an oxidation state of at least three; and (v) an inorganic oxide material.

Description

FIELD OF THE DISCLOSURE[0001]The present disclosure relates to containers for packaging a variety of consumer goods and methods of use thereof. More particularly, the disclosure relates to packaging for products that are derived from or that otherwise incorporate tobacco, and which are intended for human use or consumption.BACKGROUND OF THE DISCLOSURE[0002]Various types of containers for dispensing solid objects, particularly solid products intended for human consumption, are known in the art. Such containers are often characterized by a hand-held size that can be easily stored and transported. Exemplary consumable products that are often packaged in such containers include a wide variety of consumer products, including smokeless tobacco-related products.[0003]Tobacco may be enjoyed in a so-called “smokeless” form. Particularly popular smokeless tobacco products are employed by inserting some form of processed tobacco or tobacco-containing formulation into the mouth of the user. See...
