DISPENSING BOTTLE
Abstract
Described is a plastic bottle fitted with a one-way check valve
and an inner bladder containing a substance such as mustard or
ketchup. When squeezed, the substance is dispensed from an inner
bladder through an aperture in the top. When released, air is
allowed into the bottle through the valve to displace the substance
dispensed. Since the valve will not allow air out of the bottle,
the bladder continuously shrinks until all the substance is
dispensed without any waste or the need to strike the bottle or
store it upside down. No air comes into contact with the substance
thus avoiding bacterial contamination.

Claims
1. A dispensing bottle or container for dispensing a food
substance, such as ketchup, mustard or a cosmetic substance such as
hair conditioner or shampoo, that is manufactured from any flexible
material such as PVC plastic. a) A bottle that is equipped with an
inner elastic bladder, or other stretchable container, that is
capable of being filled with a substance without the substance
itself coming in contact with the inside walls of the bottle. b) A
bottle containing a one-way valve which will not allow air to
escape from the inside of the bottle when the bottle is squeezed
but allows air into the bottle when the bottle is released. c) A
bottle that has an aperture at one end to force a substance to
escape when the bottle is squeezed. d) A bottle cap that will allow
the aperture to be sealed when not in use.
2. A dispensing bottle in claim 1 wherein the bottle is
manufactured from a flexible material that will return the bottle
to its original shape after being squeezed and released.
3. A dispensing bottle in claim 1 wherein a thin, elastic, inner
bladder stretches to fill the outer bottle when the bladder is
filled with a substance to be dispensed.
4. A dispensing bottle in claim 1 wherein a one-way check valve
located on the surface of the outer bottle will not allow air out
of the bottle when it is squeezed, but will allow air into the
bottle when the bottle is released.
5. A dispensing bottle in claim 1 wherein an aperture allows a
substance to be forced from the inner bladder by the act of
squeezing the bottle.
6. A dispensing bottle in claim 1 where the inner bladder prevents
any air from coming into contact with a contained substance,
preventing bacterial degradation, hardening or break down of the
substance.
7. A dispensing bottle in claim 1 wherein an inner bladder
contracts as the contained substance is dispensed by the act of
squeezing the bottle. After releasing the bottle, the bladder stays
in its contracted state because air is allowed into the space
between the bottle and the bladder by the one way check valve. The
said air displaces the space previously occupied by the dispensed
product.
8. The method of claim 7 wherein the repeated squeezing and
releasing of the bottle causes the inner bladder to shrink as it
dispenses more of its contained substance through the aperture. The
inner bladder will continue to shrink as the substance is dispensed
until virtually all the substance has been dispensed from it.
Description
BACKGROUND OF THE INVENTION
[0001] The invention refers to a flexible plastic bottle or
container for dispensing liquids or viscous substances from an
inner, elastic bladder when squeezed. When released, a one-way
check valve on the surface of the bottle allows air into the bottle
to displace the substance dispensed from the bladder. The one-way
check valve will not allow air out of the bottle. Thus, repeated
squeezing and releasing maintains the air pressure on the inner
bladder causing the bladder to continue to shrink until all the
substance has been dispensed, thus eliminating waste of any
un-dispensed substance. No air is allowed to enter the inner
bladder or come into contact with the substance contained therein,
thus eliminating bacterial contamination or degradation of the
substance.
[0002] The bottle may be used to dispense substances such as
ketchup, mustard, salad dressings and other condiments of varying
viscosities. It may also be used for dispensing body care products
such as shampoos and body conditioners. This bottle is also useful
for dispensing beverages and other liquids. The existing types of
dispensing containers and bottles used today, allow air to enter
the bottle and come into direct contact with the contents. This
causes the contents to be contaminated with bacteria from the air,
thus creating a health risk. It also allows the contents to
separate, break down, degrade and harden causing the contents to be
inedible or unusable. When the substance is dispensed from an
existing bottle, it sticks to the sides of the bottle, and the
bottle has to be struck to get the contents to the top outlet of
the bottle in order to dispense the substance. In many cases the
air in the bottle causes unpleasant sounds and an unwanted splatter
of the substance on to one's person, clothing, table top, or
furniture as it is being dispensed. Some bottles are manufactured
with large flat tops that allow the bottle to be stored upside-down
causing the contents to flow to the top of the bottle by gravity.
Even without the flat top, these bottles and containers are often
stored upside down to allow the contents to flow downward by
gravity, in an attempt to dispense as much of the contents as
possible and to avoid waste. Depending on their viscosity, some of
the contents adhere to the sides of the bottle and are thrown away
and wasted.
OBJECTS OF THE INVENTION
[0003] The object of this invention is to allow the contents within
the bottle to remain in an air-free environment, thus virtually
eliminating the risk of bacteria coming into contact with the
contents and consequently creating a health risk. The air-free
environment will also reduce separation, degradation, and hardening
of the contents over time, and avoids splatter when the contents
are dispensed. Another object is that, since no air is allowed to
mix with the contents, the contents may not need to be refrigerated
for longer periods of time without spoiling. Another object is to
allow the contents to be dispensed from the bottle without the need
to strike the bottle to move the contents to the top. Another
object is that the bottle may now be stored upright, or in any
other position, and the contents will always be at the top opening
ready for release no matter how much substance is left in the
bottle. This avoids the need to store the bottle upside down in
order to allow the contents to flow to the top by gravity. Another
object is that this invention reduces waste by allowing virtually
all the contents to be dispensed from the bottle.

DESCRIPTION OF THE DRAWINGS SHOWING THE OPERATION OF THE DISPENSING
BOTTLE--FIG. 2
[0013] The present invention relates to a bottle (FIG. 2-1) that
allows a substance such as ketchup, mustard or shampoo to be
dispensed by squeezing the bottle. The inner bladder (FIG. 2-2) is
filled with a substance (FIG. 2-4). Squeezing the bottle allows the
air (FIG. 2-3) inside the bottle to apply pressure to the inner
bladder that is filled with the substance, thus forcing the
contents from the bladder through the top aperture of the bottle
(FIG. 2-6). Releasing the pressure on the bottle allows the bottle
to return to its original shape and, at the same time, allows more
air to be drawn into the bottle through the one-way check valve
(FIG. 2-5) to replace the dispensed substance. The check valve may
be placed anywhere on the bottle as long as the air is allowed to
enter the valve and into the space between the bladder and the
bottle. The next time the bottle is squeezed, the air inside the
bottle is prevented from escaping due to the one-way check valve
(FIG. 2-5), thereby applying pressure to the inner bladder
containing the substance and forcing it out through the top
aperture. A protective cap (FIG. 2.7) over the top aperture
prevents the collection of bacteria.
