摘要:
A container for liquids, semi-liquids, powders and similar flowable fluids comprises a substantially airtight body (10) for storing the fluid, a means for varying the pressure of gas above the level of the fluid in the body of the container, e.g. resilient flexible container walls such as a squeeze bottle, an air pocket structure (22) disposed at the lower end of the container, and in free fluid communication with the body of the container so as to allow entry of fluid from the body of the container into the air pocket structure. Air resides in the air pocket structure when the container is disposed with its lower end downwardly. An outlet passageway (20) has an upper end (24) which communicates near the top of the air pocket structure to be disposed in air retained in the air pocket and a lower end open to atmosphere exteriorly of the container and the air pocket. Such a container holds liquids therein without dripping. To discharge the liquid or other fluid the pressure on the body (10) is increased, so as to cause liquid to rise through the air pocket (22) into the outlet passageway (20), and to issue therefrom. Upon release of the applied pressure, air is sucked back in through the passageway so as to have a cleaning effect thereon. The structure allows storage of liquid ready for dispensing, but without risk of leakage or dripping, even when exposed to fluctuations in temperature of considerable magnitude.

A compressible, i.e. squeeze-type, liquid dispenser comprises a liquid container (70) which includes a structure (76, 78) establishing an auxiliary air chamber within the container associated with an outlet structure (86) extending through the sidewall of the container such that by compressing the container the contents can be discharged through the container sidewall as contrasted with being discharged through a top or bottom wall as with prior art dispensing type containers. The auxiliary air chamber provides temperature compensation and suck-back to provide drip-free operation in normal use.

Un conteneur pour des liquides, des semi-liquides, des poudres, et autres fluides semblables pouvant couler comprend un corps sensiblement etanche a l'air (10) de stockage du fluide, des moyens de variation de la pression d'un gaz au-dessus du niveau du fluide dans le corps du conteneur, par exemple des parois du conteneur flexibles elastiques telle qu'une bouteille comprimable, une structure a poche d'air (22) disposee a l'extremite inferieure du conteneur, et en communication fluide libre avec le corps du conteneur de maniere a permettre l'entree de fluide provenant du corps du conteneur dans la structure de poche d'air. De l'air reside dans la structure de poche d'air lorsque le conteneur est dispose avec son extremite inferieure dirigee vers le bas. Un passage de sortie (20) possede une extremite superieure (24) qui communique a proximite du sommet de la structure de poche d'air a disposer dans l'air retenu dans la poche d'air et une extremite inferieure ouverte mise a l'atmosphere a l'exterieur du conteneur et de la poche d'air. Un tel conteneur contient des liquides sans pertes. Pour vider le liquide ou autre fluide on augmente la pression sur le corps (10), de maniere telle que le niveau du liquide monte au travers de la poche d'air (22), dans le passage de sortie (21) pour sortir par ce dernier. Lorsqu'on fait tomber la pression appliquee de l'air est re-aspire a l'interieur au travers du passage en ayant un effet de nettoyage sur ce dernier. La structure permet le stockage d'un liquide pret a etre distribue, mais sans risque de fuite ou de pertes, meme lorsqu'il est expose a des fluctuations de temperature considerables.

A liquid dispenser which comprises a substantially airtight container (10) for storing liquid to be dispensed with the container being formed with a downwardly-extending, constricted liquid passageway (20) and a cap member (22) with an open top in liquid-sealed engagement with the lower end of the container to define a chamber within the cap member and surrounding the liquid passageway, the cap member having an outlet (195) positioned above the lower end of the liquid passageway in the chamber such that when an increase of pressure is established within the container liquid is expelled through the outlet. The chamber can dispense liquids of relatively high and low viscosities.

A dispenser is provided for liquids, the dispenser (28, 70, 110) having a container (30, 72, 112, 144, 156) and an outlet at a predetermined first level. The pressure in the container can be varied and a reservoir (44, 98, 122 and 128; 148, 174, 180) receives liquid from the outlet. A discharge passageway (46, 88, 128 and 136, 150, 184) extends upwardly from the first level and terminates at a discharge opening (52, 90, 154) at a second level, and an air relief opening (56, 102, 130, 152, 160, 182) is provided above the first level. The relief opening is no lower that the second level so that liquid displaced from the container flows into the reservoir and out of the passageway while air is trapped in the reservoir above the first level. Consequently any gradual increase in temperature will cause air from the reservoir to be displaced through the air relief opening to minimize the risk of temperature driven dispensing.

Un distributeur de liquide comprend un récipient sensiblement étanche à l'air (10) contenant le liquide à distribuer, le récipient possédant un passage de liquide (20) s'étendant vers le bas et comportant un étranglement, et un capuchon (22) dont le sommet est ouvert et qui est en engagement étanche au liquide avec l'extrémité inférieure du récipient, pour définir une chambre à l'intérieur de l'organe de capuchon et entourant le passage de liquide, le capuchon possédant un orifice de sortie (195) disposé au-dessus de l'extrémité inférieure du passage de liquide dans la chambre, de sorte que lorsqu'une augmentation de la pression se produit dans le récipient, du liquide est expulsé par l'orifice de sortie. La chambre peut distribuer des liquides de viscosités relativement élevées et faibles.
摘要:
A liquid feed device, e.g. a room deodorizer, a plant feeder or a dispenser for a toilet bowl cleanser, has a main body (26) of liquid in an upwardly closed container (11) and an air chamber structure (20) within the container and in communication with the body (26) of liquid to allow the liquid to flow into the air chamber structure (20) to form therein an auxiliary body (27) of liquid beneath an air space (31) in the structure (20). An outlet passage (16) extends from the air space (31) to the exterior of the chamber (20) and a wick (w) or other device is provided within the air chamber structure (12) for continuously transferring liquid from the auxiliary body (27) of liquid, through the outlet passage (16) to the exterior of the container (11). A partial vacuum in the container (11) above the main body (26) of liquid limits the 'level of the auxiliary body (27) of liquid.
