Abstract
A container with a discharge valve attached defines an interior volume containing a liquid. A rigid dip tube is connected between the valve and a flexible dip tube. This flexible dip tube, in turn, is attached to a weighted pick-up head. The pick-up head is formed of a buoyant portion and a weighted portion, such that the head is self-righting but does not float. A conduit, which may be continuation of the flexible tube, extends through the pick-up head to an inlet on the lower face of the head. The configuration of the head provides spacing between the inlet and the container walls such that the inlet always is in communication with the liquid.
Claims17
An all directional fluid pick-up, adapted for use with a container defining an interior volume capable of containing a liquid of known specific gravity and having a valve means on the container capable of selectively opening and discharging liquid from the interior volume of the container, wherein the fluid pick-up comprises:
- a flexible dip tube;
- a connecting means for, in use, connecting the valve means with a first end of said flexible dip tube;
- a pick-up head connected to the flexible dip tube, wherein the pick-up head is formed of first and second portions, the first portion is of lower density than the second portion such that the first portion is adapted, in use, to be buoyant within the liquid and exert, a self-righting influence on the pick-up head as a whole, and the second portion is of sufficiently high density that, in use, the pick-up head as a whole is non-buoyant within the liquid;
- and
- a conduit means carried by the pick-up head, extending through the first and second portions of the pick-up head, connected to the flexible dip tube near the first portion of the pick-up head and having an end forming an inlet housed in said second portion of the pick-up head at a position substantially opposite from said first portion, for, in use, receiving and transmitting the liquid through the pick-up head to the flexible dip tube and, in use, to said valve means.
An all directional fluid pick-up, comprising:
- a container defining an interior volume capable of containing a liquid of known specific gravity;
- a valve means on said container capable, in use, of selectively opening and discharging liquid from the interior volume of the container;
- a rigid dip tube having a first end connected to the valve means and having a second end extending from the valve means into the interior volume of the container;
- a flexible dip tube having a first end connected to said second end of the rigid dip tube and having a second end;
- a pick-up head connected to said second end of the flexible dip tube, wherein the pick-up head is formed of first and second portions, the first portion having lower density than the second portion such that the first portion is adapted, in use, to be buoyant within the liquid and exert a self-righting influence on the pick-up head as a whole, and the second portion has sufficiently high density that, in use, the pick-up head as a whole is adapted to be non-buoyant within the liquid;
- the pick-up head being joined to the flexible dip tube near said first portion;
- and
- a conduit means carried by said pick-up head, extending through the first and second portions of the pick-up head, the conduit means having a first end connected to said flexible dip tube near the first portion of the pick-up head and having a second end forming an inlet housed in said second portion of the pick-up head at a position substantially opposite from said first portion for receiving and transmitting said liquid through the pick-up head to the flexible dip tube and, in use, to said valve means.
An all directional fluid pick-up, comprising:
- a container defining an interior volume containing a liquid of known specific gravity;
- a valve means on said container capable of selectively opening and discharging said liquid from the interior volume of the container;
- a rigid dip tube having a first end connected to the valve means and having a second end extending from the valve means into the interior volume of the container;
- a flexible dip tube having a first end connected to said second end of the rigid dip tube and having a second end;
- a pick-up head connected to said second end of the flexible dip tube, wherein the pick-up head is formed of first and second portions, the first portion having lower density than the second portion such that the first portion is buoyant within said liquid and exerts a self-righting influence on the pick-up head as a whole, and the second portion has sufficiently high density that the pick-up head as a whole is non-buoyant within said liquid;
- the pick-up head being joined to the flexible dip tube near said first portion;
- and
- a conduit means carried by said pick-up head, extending through the first and second portions of the pick-up head, the conduit means having a first end connected to said flexible dip tube near the first portion of the pick-up head and having a second end forming an inlet housed in said second portion of the pick-up head at a position substantially opposite from said first portion for receiving and transmitting said liquid through the pick-up head to the flexible dip tube and to said valve means.
