Abstract
ABSTRACT OF THE DISCLOSURE
The present invention provides a blow molded container comprising a thin walled hollow body portion defining a closed chamber. An upwardly extending pouring spout is formed in the upper portion of the container. An air inlet conduit is formed by a pinched portion of the thin walled hollow body portion. The air conduit extends from the pouring spout to the upper portion of the closed chamber formed by the hollow body portion. The portion of the air conduit formed in the pouring spout is preferably parallel to the normal axis of the pouring spout. The air conduit may also include drain means to allow any liquid which inadvertently enters said conduit to flow back into said closed chamber.

CONTAINER FOR LIQUIDS
This invention is in the field of containers for liquids which permit a substantially constant flow of liquid therefrom and specifically the present invention relates to a blow molded container including a thin walled hollow body portion defining a closed chamber having an upwardly extending pouring spout formed in the upper por-tion thereof and an air inlet conduit formed by a pinched portion of the thin walled hollow body portion extending from the pouring spout to the upper portion of the closed chamber of the hollow body portion~
BACKGROUND OF THE INVENTION
Small containers used for the storage of liquids and with a single aperture through which the liquid is dispensed tend to pour unevenly. This is due to the liquid entirely filling the aperture as the container is tilted and the liquid is poured out, As liquid leaves the container the pressure drops in the increasing air space within the container. After some time, the difference between the pressure inside the container and the atmo-sphere is such that air is suddenly drawn into the con-``tainer and the flow is interrupted momentarily. The ~low then continues and the pressure difference increases until flow is again interrupted as air is drawn in. This sequence is repeated until the level of liquid is reduced to the point where a permanent air space is formed between the inside of the container and the atmosphere. By this stage the liquid is not filling the entire aperture area and the flow ls smoother.
It has heretofore been suggested in the art toprovide air vents in containers to permit air to enter the container as the liquid is poured to provide for even flow of the liquid from such a container. However, none of the prior art shows a container incorporating an air vent which is readily formed by blow molding and which effec-tively allows even flow of liquid from the container.

SUMMARY OF THE INV~NTION
The present invention provides a blow molded con-tainer comprising a thin walled hollow body portion defining a closed chamber having an upwardly extending pouring spout formed in the upper portion thereof, said closed chamber includ-ing a handle portion adjacent to and extending to appro~i.mately the same level as said pouring spout and an air inlet condu.it Eormed by a pinched portion of said thin walled hollow body portion, said air inlet conduit extending from said pouring spout into and through a substantial portion of the handle por-tion and opening in the upper portion of said closed chamber formed by said hollow body portion.
osJEcTs OF TEE INVENTION
It is an object of the present invention to provide a container for a liquid which will permit a substantially con-stant flow of liquid to be obtained therefrom when in use, which container is blow molded and has a pinched portion forming an air conduit extending from the closed interior of the con-tainer to the pouring spout thereof. Further objects and ~0 advantages of the invention will be apparent from reading the deta.iled description of the invention in light of the drawings which are made a part of this specification.
