Definitions

  • This invention provides a dispenser used for dispensing fluids.
  • the dispenser herein described relates to dispensing disinfectant at a constant rate onto putrefying material disposed of in a sanitary bin it will be realized that such a dispenser can be used for other functions, for example in a controlled experimental environmert wherein nutrient is to be added to a soil compound to promote the growth of a plant, or, in fact, in any situation where a controlled flow of fluid is required over a period of time.
  • this invention consists in a dispenser comprising a container adapted to hold a charge of fluid to be dispensed, a wick extending from within the container to the exterior thereof through a wick passage piercing a wall of said container, means to maintain atmospheric air pressure about said fluid in said container as said fluid is dispensed therefrom and support means to secure said dispenser above or beside a target onto or into which said fluid is to be dispensed; said wick passage being such that the wick therein is compressed to regulate flow through the passage along the wick at a pre-determined rate.
  • the atmospheric pressure is maintained about the fluid to be dispensed by providing a sealed, collapsible container, such as a bladder, which maintains equal pressure on the inside and outside of the container.
  • a sealed, collapsible container such as a bladder
  • An alternative means of equalizing pressure is to provide a vent in the container allowing air movement into the container, thereby preventing pressure differentials from developing across the walls of the container.
  • Figure 1 represents an embodiment of a dispenser according to the invention.
  • Figure la is a representation of a side view of the dispenser of Figure 1.
  • Figure 2 is a second embodiment of a dispenser according to the invention.
  • Figure 3 is an exploded view of the lower end of the dispenser of figure 2.
  • the dispenser comprises a sealed, collapsible bladder (1) containing fluid (2) to be' dispensed via the wick (3) .
  • the bladder is filled via the fill point (4) to a pre-determined level marked by a fill mark (5) .
  • the wick and surrounding bladder is cut at the cut point (6).
  • the sealed collapsible bladder (1) compresses, thus maintaining atmospheric pressure inside the bladder.
  • the wick (3) is preferably produced such that it is integral with the bladder (1).
  • a dispenser (11) comprises a container (12) to hold a charge of fluid, a wick (13) which extends from within the container (12) to the exterior passing through a wick passage (14) piercing a lid (15) of the container (12).
  • the primary function of the wick passage (14) is to compress the wick as it passes through the lid (15) of the container (12).
  • the compression of the wick (13) aids in regulating the flow of fluid along the passage and thereby maintains a predetermined rate of flow.
  • An aspirator tube (16) also passing through the lid (15), extending the full length of the container (12), may be used to bleed atmospheric air into the container thereby equalising the air pressure in the space above the fluid in the container with the external atmosphere.
  • the wick passage (14) and aspirator tube (16) are held firmly in place within the lid (15) by utilizing an interference fit and a glue compound (17), washer or other sealant.
  • a hanger (18) which grasps the container (12) at or adjacent to lid (15) and near the base of the container (12) and then is hung over the side of a bin wall (19).
  • the dispenser if the dispenser is used to sanitize sanitary bins as found in girls Washrooms, a controlled flow of disinfectant can be maintained throughout the entire maintenance period.
  • wick passage (14) and the aspirator tube (16) become an integral whole with the lid (15), that is the lid (15), the wick passage (14) and aspirator tube (16) are moulded into a one piece moulding.
  • the container (12) could be relatively based and shallow rather than tall and deep so as to minimize the change in head of the fluid as it flows from the container.
  • containers may be altered in external shape and internal shape to an extent which may be readily determined by experiment without departing from the scope hereof.

Abstract

L'appareil décrit, qui sert à distribuer des fluides à un débit constant pendant une certaine période, comprend un récipient destiné à contenir un volume de fluide à distribuer, une mèche s'étendant depuis l'intérieur vers l'extérieur du récipient à travers un passage qui perce une paroi du récipient, un organe destiné à maintenir l'air à une pression atmosphèrique dans le récipient au fur et à mesure que le fluide est distribué et un organe de support servant à fixer le récipient au-dessus ou à côté d'une cible sur laquelle ou dans laquelle le fluide doit être distribué. Le passage de la mèche est conçu de sorte que la mèche qui se trouve à l'intérieur est comprimée de façon à réguler l'écoulement du fluide traversant le passage à un débit prédéterminé.
