Benefits of technology

[0009] Further according to the present invention, there is a method for reducing the permeation of moisture into a dispensing tube container. The container has a head and a tube sleeve. The head has a shoulder and a neck. The tube sleeve has two ends with one end thereof attached to the shoulder. The method has the step of adding a dessicant to the head in an amount sufficient to reduce the permeation of moisture through a portion of or the entirety of the head.

Problems solved by technology

Some products are particularly sensitive to pre-mature moisture penetration or infiltration.
Pre-mature moisture penetration or infiltration may result in product spoilage or pre-mature curing.
Even when employing tube sleeves having barrier layers, prior art dispensing tube containers frequently do not prevent moisture penetration to a sufficient degree.

Embodiment Construction

[0014] The head of the dispensing tube container of the present invention has a dessicant therein in an amount sufficient to reduce the rate of permeation of moisture through the head relative to the rate without the dessicant. The dessicant is preferably present in the head in an amount about 0.1 to about 25 wt %, more preferably about 0.5 to about 10 wt %, and most preferably 0.5 to about 5 wt % based upon the total weight of the head. The dessicant may be present in a portion of or the entirety of the head. The dessicant may be present in either or both of the shoulder and the neck. Preferably, the dessicant is admixed substantially homogeneously throughout the entirety of the head. Alternately, the dessicant may be present in one or more film layers at the interior or exterior surfaces of the head.

[0015] The dessicant may be any substance which reduces the rate of permeation of moisture (water vapor) when dispersed in the head. The dessicant may reduce the rate of permeation by...

Abstract

Disclosed is a plastic dispensing tube container. The container has a head and a tube sleeve. The head also has a dessicant therein in an amount sufficient to reduce the permeation of moisture through a portion of or the entirety thereof.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a plastic dispensing tube container exhibiting reduced moisture penetration or infiltration. The present invention further relates to a method for reducing moisture permeation into a plastic dispensing tube container. [0003] 2. Description of the Prior Art [0004] Plastic tube containers are employed commercially to store and dispense a variety of products, including those in the form of creams, ointments, pastes, liquids, semi-solids, lotions and the like. Products include personal care products, consumer products, and industrial products. Dispensing tube containers typically comprise a tube sleeve, a head, and a closure. The head is heat welded or otherwise affixed to or mated with an end of the tube sleeve. The head defines a shoulder and a neck extending from the shoulder with a passageway therethrough. The neck is adapted to receive and engage with a closure. The neck and the clo...
