Abstract
ABSTRACT OF THE DISCLOSURE
A liquid dispenser connectable between a shower pipe and a shower head and adapted to automatically dispense soap or bath oil through the shower head. This shower head liquid dispenser includes a tubular body connecting at opposite ends to the shower pipe and the shower head, respectively, to form a direct path for water and including an upstream section of smaller cross-section and a downstream section of larger cross-section. A liquid flow restricting internal lip projects transversely of the tubular body at the junction of the upstream and down-stream section to produce a greater liquid pressure in the upstream section than in the downstream section, despite the larger cross-section of the downstream section. The smaller upstream section is provided with a lateral outlet; the larger downstream section is provided with a lateral inlet; a soap or bath oil reservoir is removably screwed to the lateral outlet; a flexible tube connects the reservoir to the lateral inlet and forms a second liquid path with the reservoir; and a piston and spring combination is mounted in the reservoir to expel the soap or bath oil from the reservoir in response to a pressure differential on the piston and to return the latter to an inoperative position under the bias-ing action of the spring upon disappearance of the pressure differential.

~ 1~143107 relatively larger transverse cross-section. This tubular body defines a path for the passage of water from the externally threaded upstream end 4 to the internally threaded downstream end 5. Thus, this tubular body is adapted to be connected to the shower pipe at the end 4 and to the shower head at the end 5. The upstream section 2 of the tubular body is formed with a lateral outlet 6, while the downstream section of the tubular body is formed with a lateral liquid inlet 7.
A lip 8 projects transversely into the liquid path defined by the tubular body 1 downstream of the lateral liquid outlet 6, such as to regulate the pressure upstream thereof at a relatively higher value than in the larger downstream section 3.
cylindrical tank, or reservoir 9, is provided with a neck 10 which is screwed in the la-teral outlet 6 to mount the reservoir upright on the tubular body 1. The reservoir 9 is provided with a screwable cover 11 formed with an outlet 12. A piston 13 is dis-: . , ~-~ placeable up and down in the reservoir 9 and has opposite bottom and ;'.
top faces. ~ spring 14 is engaged in the reservoir 9 between the top face of the piston 13 ana the removable cover 11. Thus~ the spring 14 ~ downwardly biases the piston 13 toward an inoperative position against `~ 20 the pressure differential between the upstream section 2 ana the down-stream section 3.
A flexible tube 15 is connected at one end to the outlet : , 12 in the cover 11, and at the other end to the lateral inlet 7 of - the downstream section 3. A pinch cock 16 is connected to the flexible tube 15 to regulate the flow of soap, bath oil or other dispensable liquid through this tube. llhe pinch cock simply includes a roller 17 i and a support 18 having opposite sides 19 converging toward each other, such that rolling of the roller 17, as shown by the arrow 20 in Figure 2, will either increase or decrease pinching of the tube 15.

As the water flows in the tubular body l in the direction of - the arrows 21 in Figure 2, a pressure differential is created between ` the lateral outlet 6 and the lateral inlet 7. This pressure differential - is caused by the lip 8 in s~ite of the greater diameter of the downstream section 3 relative to upstream section 2. Thus, the higher pressure acts against the bottom face of piston 13; that is, in the upstre~m path -` section of the second nath. The lower ~ressure acts against the top face of the piston 13; that is, in the downstream path section of the second ~ath. When the pressure differential exceeds the action of the spring ; l~, the soap or bath oil above the piston in the reservoir is expelled through the tube 15 and the lateral inlet 7 to be dispensed at the shower head together with the water passing in the tubular body l.
