Benefits of technology

[0010]The present invention overcomes the disadvantages and limitations of the prior art by providing a low cost, simple and easy to use package that allows the user to dispense the contents of the package in a controlled manner. It is an object of the present invention to provide a dispensing package with uniform vertical thickness. It is a second object of the present invention to provide a dispensing package adaptable to contain materials with varying viscosities. It is a third object of the present invention to provide a method for creating and filling a dispensing package with a variety of materials, in a variety of sizes and with reduced MVT.

Problems solved by technology

Prior devices, however, have generally been unable to provide packages that are capable of dispensing liquids, gels, creams, pastes and other types of fluid and semi-fluid materials in a controlled fashion using a low cost, easy to use package.
Opening these types of packages may require additional time, and may require skills not possessed by certain segments of the population, such as young children, elderly individuals, handicapped persons, etc.
Because of this, these applicators have irregular shapes with varying vertical thicknesses causing packaging and shipping problems.
In addition, these applicators create problems for users because they are bulky to store and transport and the large raised portions are vulnerable to puncture whereby the liquid can leak out of the applicator.
Problems associated with needle fillers include delivering imprecise volumes of material within the container, creating an additional puncture point in the container and being limited to materials with certain viscosities.
Additionally, these containers suffer from a very high moisture vapor transmission (MVT) rate thereby allowing product to evaporate and dry out.

Embodiment Construction

[0052]FIG. 1 is a perspective view of one embodiment of a dispensing package 100 in accordance with the present invention. Dispensing package 100 may take on any shape whatsoever such as square, round, rectilinear, triangular, etc. Dispensing package 100 has a plastic backing 102 made of thin plastic materials such as polystyrene, polyethylene, polypropylene or other polymeric or plastic type of material. Plastic backing 102 has a sufficient thickness and stiffness to hold dispensing package 100 in a substantially flat configuration. Located on the top surface of dispensing package 100 is a label 104. Label 104 can comprise any desired type of label including clear plastic labels, printed labels, etc. Label 104 can be attached to plastic backing 102 using a pressure sensitive adhesive, a heat curing adhesive or any other desired type of adhesive. Those in the art will appreciate that pressure sensitive layer 102 and label 104 may be eliminated entirely and printing can be done direc...

Abstract

A package for carrying and dispensing contents through at least one metered opening includes a plastic backing having a first elastic limit and a shear modulus sufficient to maintain the package in a substantially flat configuration; a first score extending at least partially into the first side of the plastic backing; a coating formed on a second side of the plastic backing having a second elastic limit that is greater than the first elastic limit; a pouch formed on the second side of the plastic backing that is adapted to carry the contents of the package. Flexure of the plastic backing by a first amount is sufficient to cause the plastic backing to exceed the first elastic limit and break along the first score while flexure to a folded position is insufficient to cause the coating to exceed the second elastic limit.
