Description:

FIELD OF THE INVENTION

The invention is a cap to be used on water containers and, more specifically, is a container cap assembly in which a tablet of water additives may be placed for dissolution in the water of the container as the water flows out of the container.

BACKGROUND OF THE INVENTION

It is often desirable to purchase water which has various additives added to it. This can include nutrients, minerals, vitamins, colorings, flavorings, medicinal materials, herbal remedies, chemicals and other additives of water. These are often supplied with the water itself and sold as water designed for a certain task. The disadvantage with water prepared with such an additive is that the water container might be disposable, so when it is utilized it becomes waste. The pre-mixed water may also have to be transported for a long distance, which adds greatly to the cost of the product.

What is needed is a cap for a container which allows a tablet of water additive to be added to the cap, in order to enable the cap to be shipped to the point of consumption, rather than the water with the additive. Such a cap could also allow refilling the tablet containing the water additive, which would allow the re-use of a single water container a number of times. With such a system, waste would be reduced and prepared water would not have to be shipped. This would all be a cost saving to the user who could merely buy one cap and a number of water additive tablets as he would choose. In this way, the user can also select his own water additives and might mix and match a number of different water additives to create his own concoction of supplemented water.

SUMMARY OF THE INVENTION

The invention is a container cap assembly for attachment to a water container, with the container cap assembly having the capability of holding additives for addition to the water. The container cap assembly is configured so that the additives are added to the water as the water passes out of the water container.

The additives that may be added to the water in this manner include: vitamins, such as multi-vitamins, vitamin C, vitamin D, vitamin A, B-complex; as well as minerals, such as Calcium, Strontium, Fluorine, Potassium and Sodium. In addition to vitamins and minerals, the container cap of the invention can include colorings, flavorings, water purifiers, and other chemicals which may be desirable to add to water. These could include materials for aromatherapy, appetite suppressants, herbal mixtures, protein additives, antibiotics, nicotine, antioxidants, ginseng, caffeine, or other stimulants, and medicines. In addition to products for human consumption, products such as pesticides, herbicides, plant fertilizers and other chemicals could be added to water from a container, for use in the home, garden, lawn, roadways and on pets.

Each of these water additives is configured in a tablet or pill form as a solid which is mixed with selected ingredients which cause the tablet or pellet to dissolve at a selected rate. Generally, the tablet, pill or pellet is configured to dissolve at a rate selected for the volume of water in the water container, so that when the water container is emptied, the contents of the tablet would be fully dissolved and would have been dispensed with the water exiting the container.

The tablet can also be configured for a more long lasting dispensing time so that one pellet might serve for several or many refillings of the water container.

The device of the invention includes a cap body which further includes a fitting for attaching the cap body to the container. The cap body also includes a closure valve for opening and closing a passage for the release of water from the container.

The container cap assembly further includes a tablet basket which is configured for receiving a tablet, with the tablet being composed of a substance which is desirable to add to water or another portable liquid in the container. When water is dispensed from the container, it passes through the tablet basket, and gradually dissolves the tablet in the outflow of water.

The container cap assembly can be designed with a selected tablet in a tablet basket so that when the tablet is dissolved, a new cap would be placed on the container. The container cap assembly can also be configured so that a new tablet can be placed in the tablet basket, and the tablet may be replaced periodically when the user chooses to refill the container cap assembly. In order to refill the cap assembly, a capsule access port is provided for adding a tablet to the cap body.

The tablet may be made up of a mixture of ingredients, which can be selected from the list, including, vitamins, minerals, medicinal herbs, water purifiers, antibiotics, colorings, flavorings, or other additives which may be desirable to add to domestic tap and non-potable water.

The cap body may be divided into two parts, with one part being a cap base and another part being a cap top. The cap top and the cap base would be joined to each other using a connection interface. The cap base would include a container fitting interface, which would attach to a selected container.

Water containers with which the container cap could be utilized include, individual-sized drinking water containers such as a plastic bottle containing a quart, half a liter, or a liter of water. Other types of water containers could include, insulated jugs such as a picnic-sized water container, or industrial-sized such as 5 or 10 gallon water containers. For each of these, a cap would be configured to fit on the water dispensing spout of the water container and the particular tablet to be used with that size of container would be provided for certain volume and time release period of the additive. Other water containers can include a flexible bladder, containing water, which can be sized from a personal size, such as one liter; to larger sizes, such as three liters; and even larger sizes, such as those used in military and disaster recovery situations, such as a large bladder containing many thousands of gallons of water. The container cap assembly of the invention can also be fitted to other types of water containers, such as truck mounted water containers which would be carried on the bed of a truck and could hold many thousands of gallons of water.

The interface between the cap base and the container would typically be a threaded connection, but other connections are also possible, such as a permanent attachment or by the use of a half rotation type connection or other conventional cap attachment means. The interface between the cap base and the cap top would also typically be a threaded connection, but other types of connection would also work, such as a snap-on connection or a connection that releases by a partial rotation of the cap. The cap top can also include a basket closure which would press down against the top of the tablet basket, in order to trap a tablet in the tablet basket. The basket closure would typically be perforated with a number of holes which would allow water to flow out of the container after it has passed through the tablet basket.

The closure valve can take a number of configurations, including having a pull-out central stem which opens a passage for water to flow out of the water container. Other conventional closures for a water container are also possible in this configuration of device, including a bite valve, a screw-on bottle top, a pull-out release and other configurations of container caps.

The purpose of the foregoing Abstract is to enable the public, and especially the scientists, engineers, and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection, the nature and essence of the technical disclosure of the application. The Abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
