2 Claims. (Cl. 299-20) This invention relates to an improved liquid disinfectant dispenser for toilet flush tanks.

The primary object of the invention is to provide a simple, efficient, and inexpensive device of the character indicated which can be quickly and easily installed in and removed from a toilet flush tank, and which dispenses disinfectant directly to the body of water in the tank.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific embodiment of the invention is set forth in detail.

In the drawings:

Figure 1 is a fragmentary perspective view of a flush tank showing a disinfectant dispenser in place therein, in accordance with the present invention;

Figure 2 is a side view of the dispenser showing the cap in place thereon and the dispenser in a condition to be stored or transported;

Figure 3 is an end view of Figure 2;

Figure 4 is a vertical transverse sectional view through the dispenser taken substantially on the line 4--4 of Figure 2, and showing the cap removed and the wick extended to discharge liquid disinfectant into the water of a toilet flush tank.

Referring to the drawings in detail, a toilet flush tank designated generally which is open at the top and has removably supported thereon a conventional cover 14, and a back wall 16 which is spaced from the front wall 12 which carries a conventional control lever 18 by means of which the flush tank valve is opened to discharge the water from the tank. The subject matter so far described is conventional and forms no part of this invention except in combination therewith. The illustrated disinfectant dispenser is designated generally 20 and comprises an elongated generally flat container 22 having a top wall 24 having an opening 26 surrounded by an upwardly extending screw threaded nipple 28. Fixed in the back wall 21 of the container 22 adjacent the upper end thereof, and under normal circumstances extending downwardly from the top of the container in spaced parallel relation are tongues 30, which, as illustrated in broken lines in Figure 3 and in full lines in Figure 4, are adapted to be bent upwardly to provide a horizontal arm 32 and downwardly to provide a vertical arm 34 to define hooks which engage over the upper edge of the back wall 16 of the flush tank 10 to suspend the container 22 in. the flush tank against the back wall 16 and above the level 35 of the body of water in the tank when the tank is full. In transportation and storage of the dispenser 20 a screw threaded cap 36 is threadably engaged over the nipple 28, but during use the cap 36 is unscrewed from the nipple, as illustrated in Figure 4, and depends into the body of water in the flush tank 10. Secured to and extending axially through the open end of the cap 36 is a rod 38 having a loop 40 on its free end embracing one end of e 2,770,492 C Patented Nov. 13, 1956 a wick 42 which extends through the nipple and the tending stop bar 44 which, when the cap 36 has attained a predetermined distance below the bottom of the container 22, engages the under side of the top 24 of the container to arrest downward movement of the wick. The stop bar 44 is positioned a distance from the free end 41 of the wick 42 sufficient to enable the free end 41 of the wick to reach the bottom 43 of the container 22 so that all of the liquid contained within the container can be siphoned out by the wick and dispensed with the water in flush tank 10, it being understood that the siphoning action is achieved by reason of the capillary action exerted in the wick 42 for the liquid L contained in the container 22.

In use, the container 22 may be transported with the tongues 30 lying adjacent the back wall thereof, as illustrated in full lines in Figure 3, so as to occupy but a minimum amount of space. When it is desired to use the contents of the container 22, the tongues 30 are bent, as illustrated at 32 and 34, into hooks for engaging over the upper edge of the back wall 16 of the flush tank 10 to suspend the container in place thereon. The cap 36 is then unscrewed and the part of the Wick between the cap and the stop bar 44 is withdrawn from the container.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What is claimed is:

1. In a liquid disinfectant dispenser for a toilet flush tank, a container having front and back walls, a bottom wall, and a top wall, said back wall having hook means for engaging over the upper edge of a toilet flush tank wall, said top wall being provided with an opening, a threaded nipple on said top wall surrounding said opening, a wick extending through said opening, said wick having a first portion located within the container and a second portion outside of the container and depending along said front wall, said second portion of the wick having a lower end normally positioned below the container, and a closure cap secured to the lower end of said second portion of the wick arranged to thread over said nipple when the wick is positioned within the container, said cap serving in the normal position of said second wick portion to hold the lower end of said second wick portion below the container.

2. In a liquid disinfectant dispenser for a toilet flush tank, a container having front and back walls, a bottom wall, and a top wall, said back wall having hook means for engaging over the upper edge of a toilet flush tank wall, said top wall being provided with an opening, a threaded nipple on said top wall surrounding said opening, a wick extending through said opening, said wick having a first portion located within the container and a second portion outside of the container and depending along said front wall, said second portion of the wick having a lower end normally positioned below the container, and a closure cap secured to the lower end of said second portion of the wick arranged to thread over said nipple when the wick is positioned within the container, said cap serving in the normal position of said second wick portion to hold the lower end. of said second wick portion below the container, said first portion having a lower end resting upon the container bottom wall, and a stop bar on said second wick portion above the lower end thereof for stop engagement with the container top wall.
