ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is directed to a product dispenser having a flexible housing and a replaceable and/or refillable product cylinder containing a rotary elevator assembly which allows the dispenser to be resupplied with product and the dispenser housing to be reused. This invention is directed to an extrudable product, such as deodorant/antiperspirant.
Many product dispensers do not allow the product to be replaced or refilled once the product dispenser is empty. Subsequently, when the dispenser is empty, the user is required to discard the entire dispenser resulting in a waste of material at a large cost to the consumer and the manufacturer. The need remains for a product dispenser wherein the dispenser housing is reusable and the product is replaceable and/or refillable.
It is therefore the primary objective of the present invention to provide a dispenser wherein the dispenser housing is reusable and the product cylinder is removable allowing the product to be replaced or refilled. This invention allows for a substantial reduction in cost and materials required for consumer use.
Other objects and advantages will appear hereinbelow.
SUMMARY OF THE INVENTION
In accordance with the present invention, the foregoing objects and advantages are readily attained.
According to the invention, a product dispenser is provided which comprises: a product cylinder having a cylinder wall defining a cavity for holding a product; and a housing having a flexible wall defining an inner space for releaseably holding said product cylinder, wherein said flexible wall is configurable between a dispensing configuration, wherein said product cylinder is held within said housing, and a refillable configuration, wherein said product cylinder can be removed from said housing.
