Cap with visible float gauge

Abstract

The present invention, a cap for liquids with a visible float gauge, is comprised of a hollow, cylindrical cap made of transparent material, a color coded display of levels and/or a text display, and a fixed inner cylinder. The inner cylinder is attached to the cap top at its top end. The inner piece is concentrically placed in the cylindrical cap inside of the float gauge, and a float gauge is internally retained by the cap. The cap is then screwed on to a liquid reservoir as is found on a typical internal combustion engine, whereupon the float gauge floats on the liquid and is seen through the transparent part of the cap. The float gauge is the indicator, giving a liquid level reading.

Claims

1. A cap with visible float gauge comprised of: a hollow cylindrical cap having a first end and a second end, said cylindrical cap being made of transparent material, a plurality of liquid level markings on said cylindrical cap, an internal or external thread formed within said cylindrical cap at said second end thereof, for mounting on a liquid reservoir typically found in vehicles or machines having lubrication, liquids, or hydraulics; and a float gauge marked with color coded levels that indicate correct level on an upper portion and low liquid level on a lower portion; said float gauge being retained by an internal shoulder and said float gauge rests on said shoulder at lowest liquid level position, wherein the cylindrical cap further includes a non-floating color coded cylindrical portion for indicating a low level and the float gauge further comprises an indicator, wherein, when the liquid reservoir is at a correct level, the upper portion of the float gauge is visibly exposed through said cylindrical cap, when the liquid level is at a low liquid level, the color coded cylindrical portion of the cylindrical cap is visible through the cylindrical cap, and when the liquid level is at a high liquid level, the lower portion of the float gauge is visible through the cylindrical cap.

Description

SUMMARY OF THE INVENTION

(1) The present invention is directed to a cap. It has a visible float gauge, a cylindrical hollow cap made of transparent material, a fixed cylinder, and has color coded levels and/or text levels. The whole unit is attached to a liquid reservoir. The inner cylinder is located concentrically and attaches to the top cap at one end. The lower end is color coded and/or text coded to indicate a low liquid level.

(2) The cap is made of transparent material, and a float gauge is internally retained. The cap is then screwed on to a liquid reservoir as is found on a typical engine, whereupon the gauge floats on top of the liquid. The gauge is the indicator and rises and falls with the liquid level and gives a liquid level reading.

(3) These, together with other objects of the invention, are pointed out clearly in the claims annexed to and forming a part of this disclosure. For a better understanding of this present invention, its operating advantages and the specific objects attained by its use, reference should be made to the accompanying drawings and descriptive matter in which there are illustrated preferred embodiments of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

(4) The FIGURE illustrates the ballooned assembly vertical cross-sectional view showing all the elements.

(5) In the FIGURE, No. 1 is the actual float itself. The float has two colors. No. 7 is one color of the float and No. 9 is a different color of the float. The float moves up automatically when the fluid is being filled, and the float moves down automatically as the fluid is used or depleted.

(6) In the FIGURE, No. 4 the cap body is comprised generally of a cylindrical transparent housing No. 5 and fixed inner cylinder No. 6 which is colored yet a different color at No. 10 and the cap body is threaded at No. 3 about a portion of its exterior length. The threaded portion No. 3 is adapted to be received in mating threads No. 2 which define the reservoir fill can opening. No. 8 is the retainer, which holds the float in place.
