## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to caps, and more particularly, this invention relates to a cap for storing and dispensing additives into a container.
2. Description of the Prior Art
In the pharmaceutical, beverage, scientific, and other relevant industries, when two or more substances require mixing in predetermined amounts for creation of a desired solution, the substances are usually kept in separate containers and mixed together into a single container as necessary. The mixing procedure can be time consuming as it may require measuring or it may be messy as there may be some spilling or cleaning necessary during and after the cleaning process. It is also known that mixtures of substances in a solution can change the composition, color, or efficiency of the ingredients and solution with passage of time. For instance, in the chemical industry, mixture of compounds can create a solution having certain desired reactive properties; however, the desired reactive efficiency of the product can diminish with the passage of time. Also, in the beverage industry, many flavored drinks are comprised of a mixture of substances. With passage of time in storage, these flavored drinks can loose their freshness, taste, and appearance. In addition, with prolonged storage, undesirable precipitation of compounds may even begin to appear in these flavored drinks. Often, in many nutritional drink solutions, the efficacy of the nutrition in such a drink may be lost with passage of time after mixture of key ingredients. These disadvantages are often encountered in commercial production and sales of the above mixed solutions, which often requires prolonged storage periods.
As such, there is a need for a cap for a container which can hold substances separately in storage and release the substances for mixture just prior to use to eliminate the disadvantages described earlier.
Therefore, it is an object of the present invention to provide a cap for a container capable of storing additives and releasing the additives into the container at the desired time. It is another object of the present invention to provide a container wherein the contents in the bottle are stored separately from additives contained in a cap device attached to the bottle for mixture when the cap device is being released from the bottle.
SUMMARY OF THE INVENTION
The present invention as shown is a device for use as a cap with a container. The device holds a predetermined additive for addition to a liquid or substance within the container at the desired time. The container shown in the illustrations has a neck. The device comprises an upper cap member, a middle cap member, and a lower cap member.
The additive substance is stored in a chamber defined by the connection of the middle cap member to the upper cap member. The middle cap member has a top plate member and an aperture formed therethrough. The chamber is enclosed by, covering the aperture of the top plate member with a sliding door in a closed position. The door can be moved to an open position to uncover the aperture on the top plate member. In the open position, any contents within the chamber can exit through the aperture of the top plate member. The door further has a downwardly protruding tab member.
The middle cap member removeably connects to the lower cap member. A layer of filter can be placed between the middle cap member and the lower cap member. The middle cap member has a skirt portion having an inner surface for twistably connecting onto the outer surface of the lower cap member. The lower cap member has a top surface and an aperture formed therethrough. A catch member protrudes upwardly from the top surface. A skirt protrudes upwardly and downwardly from along the edge of the top surface to form a cylindrical wall around the top surface. The cylindrical wall and top surface of the lower cap member are constructed and arranged to receive the neck of the container therein such that an outer surface of the neck of the container is sealed by at least a portion of the inner surface of the skirt of the lower cap member.
In a locked position of the device, the lower cap member is connected to the container, and the lower, middle, and upper cap members are all connected. Furthermore, in the locked position of the device, the door is in the closed position to retain the additive substance within the chamber. The contents in the chamber are discharged into the container by twisting the middle cap member in a predetermined direction around the lower cap member. The tab member and door are constructed and arranged to engage the catch member for a predetermined distance sufficient to slide the door to the open position as the middle cap member is twisted around the lower cap member in a predetermined direction to open the device from the locked position. As the middle cap member is twisted to cause the door to open, the aperture of the middle cap member becomes aligned with the aperture of the lower cap member so that the contents in the chamber can pass through both apertures and into the container.
For storing an additional predetermined substance in the device, another embodiment has a fourth cap member attached above the upper cap member. The upper cap member is provided with an aperture through a top surface thereof. The fourth cap member defines an open well having an open bottom covered by a bottom lid to form a cavity therebetween. The bottom lid has an aperture therethrough. The bottom lid has a sliding door covering the aperture formed thereon. The door of the bottom lid can be moved to uncover the aperture of the bottom lid. In a locked position of the device, the fourth cap member is connected to the upper cap member, and the door of the bottom lid is in the closed position. As the fourth cap member is twisted around the upper cap member in a predetermined direction, the door of the bottom lid is moved to the open position. As this door moves to the open position, the aperture of the bottom lid becomes aligned with the aperture of the upper cap member to discharge any contents therein to the chamber below.
