BACKGROUND OF THE INVENTION1. Field of the Invention
The invention relates generally to liquid dispensers, and more particularly to liquid dispenser spout assemblies for dispensing liquids.
2. Description of Prior Art and Related Information
Various liquid dispensers, such as a liquid soap dispenser, have a container for containing the liquid or fluid to be dispensed, and a discharger for dispensing a predetermined amount of liquid therefrom. A typical discharger employs a manually or automatically actuated reciprocating pump attached to the container.
The conventional liquid dispensers have employed a curved or bowed spout, as shown in
There remains a need, therefore, for an improved liquid dispenser that provides a vertical discharge spout to prevent waste or accidental splashes during operation and that minimizes dripping to prevent waste and unintended discharge subsequent to operation.
SUMMARY OF THE INVENTIONIn one aspect, the invention provides a liquid dispenser apparatus. The apparatus includes a container for housing a liquid, and a spout assembly for dispensing spurts of liquid from the container. The spout assembly comprises a stopping member for stopping the dripping of the liquid after each dispensing operation.
In one embodiment, the stopping member comprises a resilient membrane. The resilient membrane is configured to bend outward under pressure from the liquid when the liquid is dispensed, and to retract when the liquid is not being dispensed. The resilient membrane may include a plurality of flap portions.
The spout assembly may further include an outlet portion and a coupler for coupling the stopping member to the outlet portion. In one embodiment, the stopping member has a central opening, and the coupler includes a projection for extending through the central opening of the stopping member, and one or more openings for dispensing the liquid.
The spout assembly may further include a connector portion, the outlet portion being configured to removably couple to the connector portion.
In an alternative embodiment, the stopping member includes a rotatable member having one or more openings. The rotatable member is configured to rotate to expose at least one of the openings to an outlet of the spout assembly for dispensing the liquid from the container, and to rotate to a closed position when not dispensing the liquid.
In a preferred embodiment, the spout assembly is configured to face substantially toward a ground level. An axis of the spout assembly, along which the liquid is dispensed, forms an angle of about 90 degrees relative to the ground level.
In another aspect, the invention provides a spout assembly for a liquid dispenser. The spout assembly includes a stopping member for stopping dripping of the liquid after each dispensing.
In a preferred embodiment, the stopping member includes a resilient membrane, and the resilient membrane is configured to bend outward under a pressure from the liquid dispenser, and to retract when the pressure is released. In one embodiment, the resilient membrane includes a plurality of flap portions.
In an alternative embodiment, the stopping member includes a rotatable member having one or more openings, and the rotatable member is configured to rotate to expose at least one of the openings to an outlet of the spout assembly for dispensing the liquid and to rotate to a closed position when not dispensing liquid.
In one embodiment, the stopping member has a central opening, and the coupler includes a projection for extending through the central opening of the stopping member, and one or more openings for dispensing the liquid. In one embodiment, the spout assembly further includes a connector portion, and the outlet portion is configured to removably couple to the connector portion.
In another aspect, the invention provides a method of dispensing liquid. The method includes providing a container for housing a liquid, and providing a spout assembly for dispensing spouts of the liquid from the container. Providing the spout assembly includes providing a stopping member for stopping dripping of the liquid after each dispensing.
Preferably, the stopping member comprises providing a resilient membrane, and the resilient membrane is configured to bend outward under pressure from the liquid from the container when the container is under a pressure, and to retract when the pressure is released. In one embodiment, the resilient membrane includes a plurality of flap portions.
In one embodiment, providing the stopping member includes providing a rotatable member having one or more openings. The method further includes rotating the stopping member to expose at least one of the openings to an outlet of the spout assembly for dispensing the liquid from the container, and to rotate to a closed position when not dispensing liquid. The spout assembly may further include a connector portion, and providing the outlet portion includes removably coupling the outlet portion to the connector portion.
In one embodiment, providing the spout assembly comprises facing the spout assembly substantially toward a ground level.
The method may further include replacing one of the container, the spout assembly, and the stopping member.
In summary, a liquid dispenser apparatus includes a container for housing a liquid, and a spout assembly for dispensing spouts of the liquid from the container. The spout assembly includes a stopping member for stopping dripping of the liquid after each dispensing, thereby allowing the spout assembly to face substantially toward a ground level to avoid splashing a user with liquids.
The invention, now having been briefly summarized, may be better visualized by turning to the following drawings wherein like elements are referenced by like numerals.
The invention and its various embodiments can now be better understood by turning to the following detailed description wherein illustrated embodiments are described. It is to be expressly understood that the illustrated embodiments are set forth as examples and not by way of limitations on the invention as ultimately defined in the claims.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTA preferred embodiment of a liquid dispenser apparatus is illustrated in
As shown in the perspective view of
As show in the exemplary configuration of
Such a substantially vertical configuration of the spout assembly 26 is not normally used in conventional liquid dispensers, such as that shown in
Referring now to
The preferred spout assembly 26 comprises an outlet portion 34, and a connector portion 36. The outlet portion 34 may be threadably coupled to the connector portion 36 using threads 38. Those of ordinary skill in the art will recognize that other means for coupling are possible between the outlet portion 34 and the connector portion 36. The preferred outlet portion 34 can be easily attached to the connector portion 36 during assembly, and can be easily removed from the spout assembly 26 for cleaning to avoid clogging, or for replacement.
As shown, the preferred outlet portion 34 comprises a stopping member 32, which may be removably, or fixedly, coupled to a coupler 40 of the outlet portion 34 by stretching an aperture in its center around and beyond an expanded head of a projection 40d of the coupler 40. The stopping member 32 can be easily replaced if needed. In accordance with a preferred embodiment of the invention, the stopping member 32 is composed of a resilient membrane that is pushed open by the pressure from the liquid as indicated by arrows 42. When the pressing force 28 is released, the stopping member 32 retracts back to its original position adjacent the coupler indicated by a plane 40a. The resilient force of the stopping member 32 contributes to the retraction of the stopping member 32. A suction force inside the bottle 22 when the pressing force 28 is released may also assist in sealing the stopping member 32 against the coupler 40.
As shown in
In the preferred embodiment of
In the following, a method of dispensing liquids is summarized with reference to the drawings. As shown in
Many alterations and modifications may be made by those having ordinary skill in the art without departing from the spirit and scope of the invention. Therefore, it must be understood that the illustrated embodiments have been set forth only for the purposes of examples and that they should not be taken as limiting the invention as defined by the following claims. For example, notwithstanding the fact that the elements of a claim are set forth below in a certain combination, it must be expressly understood that the invention includes other combinations of fewer, more or different ones of the disclosed elements.
