ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to bottles, and more particularly, to a bottle having a wax plug in the neck thereof which dissolves in the presence of heat in order to dispense the contents in the bottle.
Dishwashers have a tendency to accumulate calcium, lime, scale, etc. over time on the walls thereof, particularly in areas having hard water. In many dishwashers, there is a short duration pump cycle, for example, for fifteen seconds, in which all liquid contents in the dishwasher are pumped out, prior to starting the cleaning operation. Therefore, any cleaning liquid placed in the dishwasher at the start of operation is merely pumped out and does not clean the walls of the dishwasher.
Although compartments are provided for a viscous dishwashing liquid or a dishwashing powder, these compartments are not suitable for holding a non-viscous cleaning liquid for cleaning calcium, lime, scale, etc. from the dishwasher walls.
Therefore, there is a need for forming a way to dispense the non-viscous liquid into the dishwasher during the wash cycle, without opening the dishwasher at this time and pouring the cleaning liquid into the dishwasher.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a portable dispensing bottle with a dissolvable wax plug at the inlet that overcomes the aforementioned problems.
It is another object of the present invention to provide a portable dispensing bottle with a dissolvable wax plug in which the wax plug dissolves during the wash cycle in the presence of heated water.
It is still another object of the present invention to provide a portable dispensing bottle with a dissolvable wax plug that is easy and economical to manufacture and use.
In accordance with an aspect of the present invention, a dispensing bottle including a hollow main body; a neck having an opening in open communication with an interior of the main body; a wax plug in the neck, the wax plug made of a wax material that melts at a predetermined temperature; and a removable closure cap in covering relation to the opening. Further, the neck has an inner surface with one of a lip and a groove for capturing the wax plug to prevent the wax plug from falling into the main body.
In accordance with another aspect of the present invention, a dispensing bottle includes a hollow main body having an opening; a wax plug made of a wax material that melts at a predetermined temperature; and a retaining plug positioned in the opening for holding the wax plug in the opening of the bottle.
The hollow main body includes a neck having the opening in open communication with an interior of the main body; and the retaining plug is positioned in the neck for holding the wax plug in the neck of the bottle. A removable closure cap is in covering relation to the opening.
The retaining plug comprises an annular member including an outer facing peripheral surface, and an inner facing peripheral surface defining a center opening in which the wax plug is held.
In one embodiment, an inner facing surface of the opening is provided with one of a lip and a groove, and the outer facing peripheral surface of the retaining plug is formed with the other of the lip and the groove for mating with the one of the lip and the groove in the opening.
In another embodiment, an inner facing surface of the opening is provided with one of a groove and lip, and the outer facing peripheral surface of the retaining plug is formed with upper and lower tapered portions that form a substantially V-shape in cross section, and a meeting portion of the upper and lower tapered portions mates with the one of the groove and lip in the opening, to hold the retaining plug in the opening.
Also, the inner facing peripheral surface includes one of an inwardly extending lip and a groove, and the wax plug includes an outwardly facing peripheral surface with the other of the inwardly extending lip and a groove that fits within the one of the inwardly extending lip and groove.
The retaining plug includes an outwardly extending flange which rests on an upper edge of the bottle in surrounding relation to the opening when the retaining plug is positioned in the opening.
The wax plug is made from a paraffin wax, and preferably, a red paraffin wax having a melting temperature of about 125° F.
In accordance with still another aspect of the present invention, a dispensing bottle includes a hollow main body; a neck having an opening in open communication with an interior of the main body; a wax plug in the neck, the wax plug made of a wax material that melts at a predetermined temperature; and an arrangement for capturing the wax plug in the neck.
The arrangement includes a retaining plug positioned in the opening for holding the wax plug in the neck of the bottle. There is also a removable closure cap in covering relation to the opening in the neck.
The above and other objects, features and advantages of the present invention will become readily apparent from the following detailed description thereof which is to be read in connection with the accompanying drawings.
