Liquid dispenser

Abstract

A liquid dispenser for dispensing a liquid such as a hand sanitizer uses a receptacle that is dimensioned to properly fit within a typical vehicle cup holder. A receptacle cap is attached to the top of the receptacle. A pumping system passes through the receptacle cap so as to have a dip tube disposed within the receptacle and an actuator located above the receptacle cap. Actuation of the actuator draws liquid from the receptacle and dispenses the liquid onto a user's hand through a discharge portion of the actuator. Spilled liquid is captured within a collection pool defined on a upper surface of the receptacle cap. An protective dome cap is attached to an upper portion of the receptacle cap, has an opening therein for access to the discharge port, and can be pressed downwardly to actuate the pumping system.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(7) Referring now to the drawings, it is seen that the liquid dispenser of the present invention, generally denoted by reference numeral 10, is comprised of receptacle 12 for receiving the sanitizer L or other desired liquid therein, the receptacle having a closed bottom 14 and an open top 16. The receptacle 12, which can be made from a variety of materials, including plastic, aluminum, glass, and the like, has an outer surface that is generally cylindrical in shape (to include an outward taper of the outer surface), at least proximate the bottom 14, and is dimensioned so that the receptacle 12 properly fits into a typical drink holder found in most modern vehicles and securely remains within the drink holder during normal driving of the vehicle.

(8) A receptacle cap 18 has an upper surface 20 and a lower surface 22 as well as a side wall 24. A central hub 26 extends upwardly from the upper surface 20 of the receptacle cap 18, the hub 26 having a through passage 28 centrally disposed therein and a seat 30 located within its inner surface proximate the hub's top. A collection pool 32 is formed by the upper surface 20, the outer surface of a portion of the central hub 26 and the inner surface of a portion of the side wall 24. As seen, an annular lip 34 encircles an outer surface of the side wall 24. A lower seat 36 encircles the outer surface of the side wall 24 below the annular lip 34 and receives an O-ring 38 therein while an upper seat 40 encircles the outer surface of the side wall 24 above the annular lip 34. The receptacle cap 18 is removably attached to the open top 16 of the receptacle 12 by pressing the lower portion of the receptacle cap 18 into the open top 16 of the receptacle 12, the receptacle cap 18 and the receptacle 12 at its open top 18 each being dimensioned so that the receptacle cap 18 friction fits into the open top 16 and snugly remains therein. The annular lip 34 sits on the rim 42 of the receptacle 12 whenever the receptacle cap 18 is secured to the receptacle 12. The O-ring 38 is pressed between the receptacle cap 18receptacle 12 engagement in order to help keep the receptacle 12 spill proof whenever the receptacle cap 18 is attached to the receptacle 12.

(9) Of course the receptacle cap can be threadably attached to the receptacle by providing appropriate corresponding threading on the receptacle cap and on the receptacle. Other attachment mechanisms can also be employed to attach the receptacle cap to the receptacle.

(10) A pumping system 44 for pumping liquid out of the receptacle 12 is provided and comprises a housing 46 that holds the pumping mechanism. The pumping mechanism can be any appropriate pumping mechanism known in the art for dispensing the target liquid to be dispensed by the liquid dispenser 10 of the present invention, including possibly electrical pumping systems, and by way of example only, herein includes the illustrated piston 48 and spring 50. A dip tube 52 extends downwardly from the bottom of the housing 46. An annular lip 54 encircles the housing 46. A U-shaped actuator 56 having a discharge port 58 is secured to the housing 46 so as to be able to engage the piston 48 of the pumping mechanism. The housing 46 is received within the hub 26 so that the housing's annular lip 54 is received within the seat of the hub 26 wherein an O-ring 60 is located, the O-ring 60 helping make the housing 46hub 26 juncture spill proof for any liquid that may be located in the receptacle 12. In this configuration, the dip tube 52 is located within the receptacle 12 and is dimensioned to terminate just above the bottom 14 of the receptacle 12.

(11) A domed cap 62 is made of silicon rubber or other such elastic material that allows it to compress and then return to its original shape with application and then release of pressure from a child's hand and arm is removably attached to the top of the receptacle cap 18. The domed cap 62 has an annular lip 64 encircling an inner surface of the domed cap 62 proximate the domed cap's bottom 66. An opening 68 sized to permit a user's hand to pass therethrough is located on the domed cap 62. The domed cap 62 is removably attached to the receptacle cap 18 so that the bottom 68 of the domed cap 62 is pressed onto the top of the receptacle cap 18 until the domed cap's annular lip 64 is received within the upper seat 40 of the receptacle cap 18. The domed cap 62 utilizes an annular reduction in thickness near its bottom 66, which due to its material, will bulge outward and allow the dome top to compress downwardly towards receptacle cap 18 in order to actuate the pumping system as seen in FIG. 5.

(12) Of course the domed cap can be threadably attached to the receptacle cap by providing appropriate corresponding threading on the domed cap and on the receptacle cap. Other attachment mechanisms can also be employed to attach the domed cap to the receptacle cap.

(13) In order to use the liquid dispenser 10 of the present invention, the receptacle 12 is filled with the desired liquid L. The receptacle cap 18 is secured to the open top 16 of the receptacle 12. The pumping system 44 is secured to the receptacle cap 18. The domed cap 62 is secured to the receptacle cap 18. The liquid dispenser 10 is positioned as desired, such as by placement into a vehicle's cup holder. As liquid L is desired, a user presses downwardly on the top of the dome 62 thereby pressing on the actuator 56, which presses onto the pumping mechanism, which causes a small amount of liquid L to be drawn into the bottom of the dip tube 52 and dispensed out the discharge port 58 of the actuator 56 onto the user's hand that is partially passed through the opening 68 of the domed cap 62of course, if the pumping system is not primed, the pumping system is primed by several press cycles on the top of the actuator 56. If the user misses dispensing the liquid L onto his or her hand (or other implement presented to catch the liquid dispensed), the liquid L is caught within the collection pool 32 of the receptacle cap 18, allowing the user to scoop this captured liquid L with his or her hand. While the domed cap 62 is not strictly required for proper operation of the liquid dispenser 10, its presence helps keep the actuator 56 clean as well as otherwise protecting the actuator 56, helps prevent accidental actuation of the pumping system 44, helps tactilely guide a user's hand to the actuator 56, and helps keep any liquid L accumulated within the collection pool 32 from spilling out therefrom, and of course, makes pressing down on the actuator easy.

(14) When the receptacle 12 becomes empty, the receptacle cap 18 is removed from the receptacle 12, the receptacle 12 is refilled, and the receptacle cap 18 replaced in the usual way.

(15) While the invention has been particularly shown and described with reference to an embodiment thereof, it will be appreciated by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention.
