Dip-tube style dispensers and dip-tube style spray dispensers for fluids particularly have widespread consumer acceptance and appeal. Such hand held dispensers are used for dispensing a variety of fluids and for a variety of uses, from dispensing window cleaning products to dispensing soap for home use. Uniformly, however, the tilting or inclination of containers for these dispensers in use and the placement of a lower end of the dip-tube are such that before all of the fluid is evacuated from a container, prime is lost and the user of the device must remove and perhaps apply or use the remaining fluid in some less convenient or efficacious way. The necessity of undertaking to remove the remaining fluid, which may or may not be substantial in volume, naturally has the effect of reducing the appeal of such dip-tube style dispensers for fluids.
Several objects and advantages of my invention are:
To keep the dip-tube submerged in the container's fluid at all times during
use of the dispenser to avoid lost of prime.
To enable a more complete withdrawal and efficient use of the fluid within said
dispenser.
To allow an easy manufacturing of a dispensing container by only modifying the
upper part of said container by inclining the neck portion or by inclining the
fastening portion at the upper end of the dispenser's neck.
Here is an image of the new style: Prime to the dip-tube is not lost when the dispenser is inclined having little fluid.
These two images show the new and existing spray bottles as they would stand
on a flat surface:
The neck of the new dispenser is incline in order to direct the dip-tube to
the side of the lower bottom.
Here is an example of what happens with the existing spray pumps:
When you pull the trigger no liquid comes out
Here is a picture of a modified bottle. The neck of this bottle was bent back
using hot water.
This bent allows the dip-tube of the pump to be oriented to the lower and deeper
corner of the liquid.
The next image shows the dispenser, as it would be if been held in a person's
hand ready to spray in a horizontal position.
The dip-tube is submerged in the fluid in this position. Lost of prime to the
tube is avoided.
The two next images show an alternative way of inclining only the fastening
portion of the upper neck
Here the mating surface of the pump to the dispenser bottle is not in a horizontal
plane.
The neck of the dispenser is shown to be vertical, although the mating surface
of the pump to the top of dispenser bottle is not in a horizontal plane.
Prime to the dip-tube is not lost when the dispenser is inclined having little fluid.
These are other styles of dispensers on where prime is lost when the bottles are incline having little fluid left.
Here prime to the dip-tube is lost when the dispenser is inclined having little fluid.
This image shows this other style of dispensers that would benefit from my invention.
Summary of the Invention
The present invention addresses the problem of loosing prime to the dip-tube
by providing an improved hand held dispenser for fluids which comprises: a container
having an upper end which has a neck or fastening opening inclined to the horizon
to force the positioning of the dip-tube to the side of the bottom of the container.
Dispensing means positioned adjacent to the upper end of the container for dispensing
a fluid held in the container and communicated to the dispensing means and a
tube for communicating the fluid upward from a lower end of the tube to the
dispensing means. The tube is of a sufficient length such that the lower end
of the tube is urged toward the side lowermost portion of the bottom to avoid
lost of prime when the container is oriented as in use.
Here are examples of existing products of the line Windex from S.C. Johnson & Son, Inc. that would benefit from my invention:
