Dosing closure and method of using
A dispensing closure assembly includes a container having a threaded finish portion, at least one modular sealed vial that contains a substance, and a closure cap that is adapted to be screwed on to the container. The closure cap includes a closure main body having a top portion and a downwardly depending sidewall portion that is adapted to be secured to the container. An insert is positioned between the closure cap and the container for opening the modular sealed vial when the closure cap is screwed on to the container. A method of dispensing a substance into the container is also disclosed.
1. Field of the Invention
This invention broadly relates to the field of packaging, and more specifically relates to a portion closure that is adapted to release a substance into a container.
2. Description of the Related Technology
Many substances that are in wide commercial use are able to be concentrated by the manufacturer and later reconstituted by the consumer by mixing the concentrated with water. It is often ecologically preferable to use concentrates rather than paying the economic and social costs of transporting the bulkier final product through the distribution chain to the consumer. In addition, concentrates tend to have a longer shelf life than the unconcentrated product. Accordingly, many products are already being sold in concentrated form, with a variety of different structures having been advanced for mixing and reconstituting the concentrate into the final product.
One disadvantage of using a concentrate is that the consumer will often end up with the concentrate or the final product on his or her hands, which in some cases may be unpleasant or unhealthy, or the concentrate, the water or the final product may be spilled on to other surfaces. A need exists for a portion closure that provides a safe and convenient way to dispensing a concentrate into a container without the concentrate ever coming into direct contact with the consumer or the surrounding environment.
SUMMARY OF THE INVENTIONAccordingly, it is an object of the invention to provide a portion closure that provides a safe and convenient way to dispensing a concentrate into a container without the concentrate ever coming into direct contact with the consumer or the surrounding environment.
In order to achieve the above and other objects of the invention, a system for dispensing a substance into a container includes a closure main body having a top portion and a downwardly depending sidewall portion that is adapted to be secured to a container; vial securing structure for securing to the closure main body a modular sealed vial that contains a substance; and unsealing structure for unsealing the sealed vial when the closure is secured on to the container.
According to a second aspect of the invention, a dispensing container assembly includes a container having a threaded finish portion; at least one modular sealed vial that contains a substance; and a closure cap including a closure main body having a top portion and a downwardly depending sidewall portion that is adapted to be secured to a container; and vial securing structure for securing the modular sealed vial; and an insert positioned between the closure cap and the container for unsealing the sealed vial.
According to a third aspect of the invention, a method of dispensing a substance into a container includes steps of securing a sealed modular vial between a container and a closure cap; and unsealing the modular vial by screwing the closure cap onto the container.
These and various other advantages and features of novelty that characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, for a better understanding of the invention, its advantages, and the objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to the accompanying descriptive matter, in which there is illustrated and described a preferred embodiment of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring now to the drawings, wherein like reference numerals designate corresponding structure throughout the views, and referring in particular to
As is shown in
Dispensing container assembly 12 further preferably includes an insert member 34 that is positioned between the container 14 and the closure 22 for unsealing the sealed modular vial 20. The sealed modular vial 20 preferably has an open bottom end that is sealed by a frangible membrane 36, which is preferably a foil laminate that is sealed to the cylindrical body of the vial 20. As may best be seen in
As is best shown in
The consumer will insert the vial 20 into the vial securing structure, and will then screw the closure cap 22 on to the container 14. As this occurs, the tip 48 of the projection 47 will penetrate and breach the membrane 36 of the vial 20, and as the vial continues to rotate with respect to the projection 47 as the closure cap 22 continues to be turned, the radial projections 50 will further tear the membrane further open, thus permitting even more of the substance within the vial 20 to escape through the passageway 52 into the container.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
