Definitions

  • This invention relates to liquid containers and in particular to a liquid container having an improved pouring neck and outlet which does not interfere with the rapid filling of the container and permits the contents of the container to be dispensed in an even stream without the gulping phenomena which occur in the dispensing of liquids from many containers currently in use.
  • the gulping phenomena is caused by the ingress of air into the container as the contents are dispensed therefrom.
  • US-A-3251514 discloses a container for liquid including a neck having a circular neck portion leading to a circular outlet, the cross-sectional area of said outlet being greater than the cross-sectional area of said neck portion, a duct forming a handle and communicating between said neck and the interior of the container, and a peripheral channel in the neck forming an area of increased cross-section relative to the cross-sectional area of the neck portion.
  • the container disclosed in US-A-3251514 has the technical problem that the positional inter-relationship between the outlet and the neck portion can cause, particuarly during intital pouring, liquid to be sucked into the inlet of the duct thereby blocking the duct and preventing smooth inflow of air into the container.
  • the duct in the handle places the outlet of the container in communication with a lower portion of the container. This has the technical problem that liquid in the container can, during pouring, pass up the duct thereby also blocking the duct and preventing smooth inflow of air.
  • US-A-4412633 discloses a container in which a duct in a handle has a U-shaped passage of small cross-section which communicates with the outlet, the passage forming a restriction to enable liquid to be blown out of the passage by a Venturi effect.
  • This container suffers from the technical problem that airflow into the container is restricted which in turn causes a slow liquid pouring rate.
  • FR-A-2070979 discloses a container having a pouring nozzle located in the neck of the container and a passage for the ingress of air into the container.
  • the object of the present invention is to provide a container of the general type referred to, which includes an air inlet duct and which permits an even flow of fluid from the container in a liquid dispensing operation.
  • the invention provides a container for liquid according to claim 1.
  • the container bottom has a finger recess therein.
  • the container may include a cap to close the container outlet.
  • the outlet, the peripheral channel and the neck portion are substantially co-axial.
  • the container 1 is of rectangular shape, it has a bottom 2, top 3, side walls 4 and end walls 6 and 7.
  • End walls 6 and 7 are angled inwardly towards the centre of the container and are so shaped as to form a neck 8 defined by inwardly directed walls 9 and 10.
  • the neck 8 has a circular neck portion 30, A circular outlet 11 leads from the neck portion 30.
  • Spaced to one side of the neck 8 is a hollow carry handle 12 having a duct 13 passing therethrough which communicates with the neck 8 above the liquid level in the container and with the interior of the container.
  • the neck is formed with a circular peripheral channel 14 above the walls 9 and 10 which communicate with the inlet end 15 of the duct 13 and positioned above the channel is the circular shaped outlet 11.
  • the bottom of the container is provided with a finger recess 16 to facilitate the tilting of the container in a liquid dispensing operation as will be explained hereafter.
  • the resulting pressure differential arising between the interior of the container 1 adjacent the entrance 15 of the duct 13 and the atmosphere draws air back into the container as illustrated by the arrows in Figs. 3 and 4 and into the container.
  • the air displaces the liquid flowing from the container also in the direction of the arrows illustrated in Figs 3 and 4.
  • the wall 10 causes the out flowing liquid to separate from the wall of the outlet 11 adjacent the inlet 15 of the duct 13 and the peripheral channel 14 provides an enlarged opening leading into the inlet 15 of the duct 13 thereby permitting a free uninterrupted flow of air into the container in a pouring operation and thereby avoiding the gulping phenomena. This is particularly important in those cases where the container is to accommodate petroleum products or toxic liquids.
