Continuous, Complete, Automatic, Non-Leaking, Non-Aerating, Positive Pressure One-Piece Vent And Pouring Combination Utilizing One Direct Venting Aperture

Abstract

A vent prevents a vacuum within an inverted container of liquid and eliminates components found in other container vents. The vent utilizes a conical or other shaped venting tube extending from the closure or a reservoir with reservoir extension and an air conduit extending inferiorly from a closure. The closure is either a leak resistant or leak proof seal. The superior aspect of the reservoir contains an inferiorly projecting air conduit, opening at the volumetric center of the reservoir. The reservoir extension projects distally into the container to reach the inferior aspect of the container. The vent provides an airway between the outside and the interior of the container so air freely passes to the distal aspect of the container without contaminating the liquid. Any liquid within the reservoir extension then collects in the reservoir during inversion of the container and then returns to the container when upright.

We claim: 
     
         1 . A container venting its interior to the atmosphere and resisting formation of a vacuum when the container is inverted to dispense a liquid therefrom, the container comprising:
 the container having a neck for the admission of liquid into the container for usage, the container having a closure upon its neck, the closure being one of an external threaded closure and an inserted plug closure, the closure having an upper exterior surface having a vent aperture and a spout aperture;   an internal venting tube in communication with the vent aperture for preventing formation of a vacuum within the inverted container having applied liquid and preventing leakage of liquid when the container is used for dispensing its liquid;   an internal accepting flange having a curved recess, the internal accepting flange being concentric with the internal venting tube;   a venting reservoir for positioning within the container, the venting reservoir having a superior aspect that locates proximate the closure, and an opposite inferior aspect, for locating proximate the bottom of the container, the venting reservoir having a proximal first end and an opposite second end projecting sufficiently downwardly into the container so that upon inversion of the container the second end extends above the liquid therein, the venting reservoir having a detent adapted for insertion into the curved recess of the internal accepting flange;   a drinking spout provided upon and extending through the closure and in communication with the spout aperture, the drinking spout provided liquid to flow out of the container when it is inverted, and the drinking spout having a liquid aperture outwardly of the spout aperture, and extending substantially above the closure of the container, and the liquid aperture being in communication with the liquid within the container such that when inverted the liquid may be dispensed; and   the spout provided upon the closure and arranged lateral of the closure in its connection, and the venting aperture arranged diametrically and spaced from the spout aperture and the spout as locating through the closure for the container, such that when the container is inverted, and liquid is dispensed from the container, the venting reservoir and its second end extending towards the bottom of the container will more quickly extend above the level of the liquid in the inverted container to accelerate the venting of air into the container during the consumption of its contained liquid.   
     
     
         2 . The container of  claim 1  wherein the vent reservoir is detachable from the internal accepting flange. 
     
     
         3 . The container of  claim 1  wherein the internal vent tube and the vent reservoir segregates air from any liquid in the container so as to minimize aeration within the container. 
     
     
         4 . The container of  claim 1  further comprising an external vent tube in communication with the vent aperture and extending out of the closure. 
     
     
         5 . The container of  claim 1  further comprising a check valve formed within the drinking spout to prevent the discharge of liquid from the container until a slight vacuum is generated upon the spout to draw liquid from within the container. 
     
     
         6 . The container of  claim 5  wherein the check valve is formed of silicone. 
     
     
         7 . The container of  claim 1  wherein the spout has a cylindrical extension connecting at one end to the spout, the opposite end of the cylindrical extension is formed as a spoon shaped device, whereby liquid may be dispensed from the container for flowing through the spout and its cylindrical extension and onto the spoon to provide for the feeding of a regulated amount of liquid. 
     
     
         8 . The container of  claim 1  wherein the second end of the vent reservoir has inherent buoyancy so as to rise to the surface of any liquid located within the inverted container to provide for the admission of air for venting of the container during discharge of any contained liquid. 
     
     
         9 . The container of  claim 1  wherein the container is a sports bottle. 
     
     
         10 . The container of  claim 1  wherein the container is a wine bottle. 
     
     
         11 . A container venting its interior to the atmosphere and resisting formation of a vacuum when the container is inverted to dispense a liquid therefrom, the container comprising:
