Solution Overview

Problem

There is a need for an enjoyable and innovative form of smokeless tobacco product that provides altered sensory properties and convenient disposal or ingestion of the tobacco formulation and its container.

Innovation Solution

A smokeless tobacco product featuring a powdered or granular formulation enclosed in a moisture-permeable container, which may include flavor agents like liquid-filled capsules or dissolvable pouches, allowing for release of flavors and tobacco components when the container is acted upon by mouth moisture, and optionally being fully ingested along with the container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tobacco is placed in a non-permeable container, then the tobacco formulation is protected from premature contact with moisture, but the release of flavor and tobacco components is delayed or prevented

Engineering Contradiction:
Improveprotection from premature moisture contactVSAvoidrelease of flavor and tobacco components
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent employs a moisture-permeable container made of porous material that allows controlled passage of moisture while maintaining structural integrity. The porosity is engineered to permit water vapor and liquid moisture to pass through, enabling flavor release and tobacco component dissolution without compromising the container's protective function during storage and handling.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The container material's permeability parameters are specifically optimized to balance protection and release functions. The material is designed with controlled pore size, hydrophilicity, and mechanical strength parameters that allow it to resist premature moisture ingress during storage while facilitating rapid moisture penetration and flavor release during oral use.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the container is made dissolvable or dispersible, then complete ingestion is enabled and disposal is simplified, but the structural integrity during use may be compromised

Engineering Contradiction:
Improvedisposal and ingestion convenienceVSAvoidstructural integrity during use
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The container is pre-engineered with dissolvable or dispersible properties that are activated only after the product has been used. The material composition and structural design ensure that the container maintains its strength and integrity during storage and initial use, then progressively breaks down or dissolves in the oral environment, enabling complete ingestion and simplifying disposal without requiring additional user actions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The container is constructed from composite materials that combine structural components for initial strength with dissolvable components for eventual breakdown. This composite structure allows the container to fulfill its protective and delivery functions during use, then transition to a dissolvable state for convenient disposal and complete ingestion, resolving the contradiction between strength and ease of disposal.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If flavor agents are added to enhance sensory properties, then user enjoyment is improved, but the complexity of the product formulation increases

Engineering Contradiction:
Improvesensory properties and flavor varietyVSAvoidproduct formulation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Flavor agents are encapsulated within the tobacco formulation or incorporated into the container structure in a nested manner. This nesting approach allows multiple flavor components to be integrated into a unified product structure, where the flavor release mechanism is built into the existing container and formulation architecture rather than adding separate complex delivery systems.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The container and tobacco formulation are designed to serve multiple functions simultaneously: protection, controlled moisture release, flavor delivery, and eventual dissipation. By making the container and formulation multi-functional, the need for separate specialized components is reduced, managing complexity while enhancing sensory versatility through integrated flavor agent delivery.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A smokeless tobacco product includes a powdered or granular smokeless tobacco formulation that is contained within a moisture-permeable packet or pouch. The smokeless tobacco formulation may include finely ground particles of tobacco in powder-like form and other ingredients such as sweeteners, binders, colorants, pH adjusters, fillers, flavoring ingredients, disintegration aids, antioxidants and preservatives. The tobacco formulation may have a dry or moist form. The container has the form of a pouch or bag, such as is the type commonly used for the manufacture of snus products. The container may contain a capsule, such as a spherical, breakable capsule. The container is intended to be placed in the mouth of the tobacco user, such that the tobacco formulation within the container may be enjoyed by the user. After the tobacco user is finished using the smokeless tobacco product, the container is removed from the user's mouth for disposal. Alternatively, the container is dissolvable or dispersible in the mouth of the user.
