Inverted Dome to Supply Dose

Abstract

The present invention relates to a dispensing closure used to house a secondary supply or dose of product and when the closure is activated dispense the secondary product or dose into a receiving vessel to which it is attached. Methods for dosing or supplying a dose of product are also provided.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates generally to the field of packages and containers, and in particular, pertains to containers having two compartments and that may be used to keep two components separate until use and dispense of one component into the other at the point of use.[0003]2. Related Art[0004]It is desirable to fit a device to the top of a beverage or other like product that can dose or supply a second product thereto.[0005]Twist to open technology provides limited opening port increased operational forces and a steep learning curve for use by the end user. Ingredients housed are often compromised when the mating components are not properly aligned. This failure breaches the seal integrity for the ingredients and may not be readily known by the manufacturer or the end user. These devices may also contain multiple parts to achieve the actions needed to house product and twist to dispense. Other products require a great d...

Benefits of technology

[0012]It is another aspect of the invention to provide a point of use dispensing device that retains the integrity and freshness of ingredients until dispension, and that minimizes exposure of contained ingredients from UV light and moisture. In some embodiments the dispensing closure device comprises an end plate seal. In one embodiment the foil end plate seal is comprised of foil. In another embodiment the foil end plate seal is lined with plastic to reinforce the seal for purposes of ingredient freshness and product integrity. In another embodiment the dispensing closure device is made with materials that block UV light. In some embodiments there is an end cap in interfering sealing engagement with the internal side walls of the housing highly polished mating surfaces which when in intimate contact provide a superior seal integrity against moisture and maintain product integrity.

[0014]Another aspect of the invention is to provide a point of use dispensing device that protects against accidental dispension. In some embodiments of the dispensing closure there are dispension-preventative components that provide protection from inadvertent, accidental or premature dispensing. In one embodiment there is a fold away tab or truss that straddles the outer surface diameter of the press part to prevent inadvertent activation and dispension. In another embodiment there is a standing radial rim connected to the proximal top of the housing and surrounding the press part beyond the proximal top of the press part to prevent inadvertent activation and dispension. In another embodiment there is a protective overcap covering the press part.

Problems solved by technology

Twist to open technology provides limited opening port increased operational forces and a steep learning curve for use by the end user.

Ingredients housed are often compromised when the mating components are not properly aligned.

This failure breaches the seal integrity for the ingredients and may not be readily known by the manufacturer or the end user.
