摘要:
A dispenser (10) uses first and second flow controls (70, 73). The flow controls maintain first and second flow ranges independent of diluent pressure within a pressure range, wherein the use solution's concentration is maintained over the pressure range. A third flow control (75) may also be utilized in a third diluent passageway for maintaining a third flow range independent of the diluent pressure within the pressure range. A bypass valve assembly (41) is operatively connected to the third incoming diluent passageway. The bypass valve has a temperature control valve. The temperature control valve having a bypass passageway, wherein additional diluent is added to the use solution, thereby controlling the use solution's concentration.

摘要:
Disclosed is a dispenser 10 for a solid chemical 13 and a method of dispensing the chemical 13. Water enters via an inlet line 22 and is sprayed from a spray nozzle 21, so that the solid chemical 13 is dispensed in the form of an aqueous chemical solution via outlet line 17. The solution's concentration is adjustable by varying the distance between the spray nozzle 21 and the exposed dissolving surface of the chemical 13. A pair of cam members 50, 51 adjust the vertical position of the solid chemical 13 with respect to the spray nozzle 21. In a preferred embodiment, a visual indication of the concentration settings is provided, with the concentration settings corresponding to the nozzle-to-eroding surface distance.

摘要:
An upright product outlet bag evacuation packaging (100, 200) includes a flexible, collapsible bag (101, 201) and a spout (116, 216) that contains and dispenses a liquid (118, 218). The bag (101, 201) includes a first wall (102, 202) and a second wall (104, 204) that are operatively connected by a seam (106, 206). When the bag (101, 201) is filled with liquid (118, 218), the first wall (102, 202) and the second wall (104, 204) are pushed away from one another thereby pulling a first side (109, 209) inward and causing an indentation (114, 214) to form. The indentation (114, 214) hinders flush contact between the first wall (102, 202) and the second wall (104, 204) as the bag (101, 201) progressively collapses as the liquid (118, 218) is dispensed. A housing (300, 400) for use with a dispenser may be used to create and reinforce the indentation (114, 214). The housing (300, 400) includes a cavity (303, 403) configured and arranged to receive the bag (101, 201). A door (302, 402) is operatively connected to the housing and includes a bar member (304, 404) which extends into the cavity (303, 304). The bar member (304, 404) contacts the bag (101, 201) with the cavity (303, 304) to create and reinforce the indentation (114, 214).
摘要:
A product dispenser and carrier (10, 110, 210, 310, 410, 510) for attachment to a surface such as a dryer fin includes a plate member (11, 111, 211, 311, 411, 511) and a product carrier (21, 121, 221, 321, 421, 521). The plate member (11, 111, 211, 311, 411, 511) attaches to the surface and the product carrier (21, 121, 221, 321, 421, 521) releasably attaches to the plate member (11, 111, 211, 311, 411, 511). Product (31, 131, 431, 531) is operatively connected to the product carrier (21, 121, 221, 321, 421, 521).
