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.
A self-adjusting pick-up tube assembly for aspirating liquid from containers of varying heights. Such assembly comprises (a) a platform member adapted to be positioned in contact with the bottom of a container when the pick-up tube is being used to aspirate liquid from such container; (b) a disk-shaped member adapted to be retained in a position proximate the container's liquid filling aperture when the pick-up tube is in use; (c) a flexible conduit interconnecting respective liquid passageways in the platform and disk-shaped members, and (d) a telescopic mount for enabling relative movement between the platform and disk-shaped members to accommodate containers of different height.
In a dispensing system such as a pressurized can or hand-pumped bottle, a liquid to be dispensed from a container flows through a composite dip tube that feeds an inlet of a liquid transfer device. The dip tube includes a straight dip tube that extends from the inlet to the bottom of the container and a U-shaped tube that extends from the inlet to the bottom of the container and then returns to the top of the interior of the container. The U-shaped tube acts as a siphon that, in combination with the conventional tip tube, provides liquid to the liquid transfer device when the container is upright, inverted, or oriented in any other position as long as one of the two open ends of the dip tube is in communication with the liquid.
An atomizer for liquids, operated manually by a lever with a trigger operating a dispensing pump with a flexible suction tube penetrating into the container in which the liquid to be sprayed is located, and having a ballast weight fixed to the suction tube. The atomizer comprises retaining structure, which can be released when required, in the form of a lever which keeps the ballast weight locked to the dispensing pump and the suction tube gathered up against the dispensing pump. The ballast weight retaining structure is released after the atomizer has been mounted on the container, once the latter has been filled. In this way the flexible suction tube is extended and can follow the ballast weight by gravity regardless of the orientation of the container. Before mounting on the container, the position of the ballast weight is locked to the dispenser and the retracted position of the flexible suction tube enables the atomizers to be handled without risk of entanglement of the suction tubes with the corresponding ballast weights.
A liquid dispenser for withdrawing liquids from one or more containers having a mouth and bottom and side walls joined at a juncture comprised of a container support to position the containers with their mouths over the lowermost part of the wall juncture, a probe support spaced above the container support, and a plurality of probes slidably supported on the probe support above the container support, each probe including a lower end with a curved face corresponding to the curvature of the juncture, each probe being moveable between a raised position above the mouth of a container, and a lowered position extending through the mouth of the container and into contact with the lowermost part of the interior of said container at the juncture, and a pump to draw liquid from the container upwardly through the probe.
A system utilizing a flaccid tube for delivery of liquids with a spray container is disclosed. This device can be substituted for the usual straight, non-flaccid tubing widely used with liquid dispensing containers. The system consists of a flexible tube and a weight attached to the end which causes the tube to seek the liquid, regardless of bottle or vessel position. The weight is attached to the tubing by a bushing or sleeve which inserts into the distal end of the flexible tube, compressing the tube walls outward resulting in a secure and tight attachment of the weight. The system allows the user to easily spray, squirt or expel liquids from any orientation which includes complete inversion of the container. The weight design components are inexpensive to manufacture, and can be easily attached to an existing spray bottle, and can thus be used, transferred, and re-used multiple times thus conserving resources.
