Fluid coupling device
Abstract
A coupling device for transferring viscous fluid, such as
catsup, from one bottle to another bottle. A lower coupling section
of the device is secured to the mouth of an upright bottle. The
other bottle is positioned inverted in an upper, flared section of
the device with its mouth adjacent the mouth of the upright bottle,
separated by a flange. An air passageway is formed in the upper
coupling section and extends through the flange into the lower
coupling section enabling air in the upright bottle to be displaced
by fluid transferred from the inverted bottle. The flared section
defines a funnel which extends from a shoulder formed in the upper
coupling section and which enables bottles of various different
sizes to be positioned therein.

Description
FIELD OF THE INVENTION
The field of art to which the invention pertains includes the field
of fluid coupling devices, particularly with respect to a coupling
device for enabling fluid in a partially filled container to be
transferred to another partially filled container.
BACKGROUND AND SUMMARY OF THE INVENTION
The use of condiments, such as catsup, in restaurants results in
numerous partially filled condiment bottles. It has been found
economically feasible to combine the contents of partially filled
bottles so that little waste occurs. To provide a rapid as well as
sanitary transfer of the condiments from one bottle to the other,
coupling devices have been designed which enable the contents of
one bottle to be transferred to a second bottle without spillage,
for example, the device in U.S. Pat. No. 3,620,267. There the
patentee attempts to enable displaced air to escape by forming an
annular expansion chamber in the coupling device. The expansion
chamber is designed to encourage air bubbles to form and quickly
penetrate through the fluid front advancing from the bottle being
emptied. However, it has been found that such an expansion chamber
does not readily provide the desired pressure relief. After
periodic use of the coupling device, the condiments tend to harden
in the expansion chamber necessitating its continual replacement.
Further, the fluid transfer between bottles is relatively slow, due
to the inadequate displacement of the air from the bottle being
filled and the coupling device must be made of different sizes for
each transferring bottle.
In order to overcome the attendant disadvantages of prior art fluid
transfer coupling devices, the present invention provides a
passageway which enables displaced air in the bottle being filled
to be rapidly released so that the fluid is quickly displaced from
a transferring bottle to the bottle being filled. The present
invention accomodates transferring bottles of various sizes and
configurations. Support means is provided for preventing movement
of the transferring bottle during the procedure. The bottle being
filled is secured to the coupling device preventing leakage of the
fluid.
Particularly, the fluid coupling device comprises an upper coupling
section into which the top portion of a bottle can be inverted. The
mouth of the receiving, upright bottle is secured into a lower
coupling section of the coupling device. The mouths of each of the
bottles are thus juxtaposed, separated by a flange defined by the
coupling section. An air passage way is formed in the upper
coupling section and extends through the flange to be adjoining
part of the coupling device. Air in the lower bottle is readily
displaced by fluid in the inverted bottle. A funnel is integrally
formed with the upper coupling section and flares outwardly at its
opening enabling bottles of various sizes and configurations to be
supported by the upper coupling section.
The advantages of this invention, both to its construction and mode
of operation will be readily appreciated as the same becomes better
understood by reference to the following detailed description when
considered in connection with the accompanying drawings, in which
like referenced numerals designate like parts throughout the
figures.

DETAILED DESCRIPTION
Referring now to FIG. 1 there is shown a fluid coupling device 12
constructed in accordance with principles of the invention. The
fluid coupling device is utilized to transfer fluid from an
inverted bottle 14 to an upright bottle 16. Normally the bottles 14
and 16 are both partially filled with similar types of fluid and it
is desirable to fill one of the bottles. While the invention is
illustrated and described as transfering fluid between bottles, it
should be understood that metal, cardboard or plastic containers
could be utilized with the invention as well. In addition, while
the invention is described as transferring a condiment fluid, such
as catsup from a first bottle to a second bottle, other fluids or
condiments could be transferred as well.
Referring now to FIG. 2, there is shown a cross-sectional view of
the fluid coupling device 12 with the inverted bottle 14 and
upright bottle 16 illustrated in dotted lines. The coupling device
12 is formed of a generally cylindrical member 20 which is divided
into an upper coupling section 22 and a lower coupling section 24.
An inwardly extending flange 28, whose interior periphery 32
defines an opening, separates the interior surface of the upper and
lower coupling sections 22 and 24. The flange 28 is formed in a
plane perpendicular to the axis of the cylindrical member 20. The
bottom surface 34 of the flange 28 defines one end of the lower
coupling section and the top surface 36 of the flange 28 defines
one end of the upper coupling section 22.
The interior wall 38 of the upper coupling section 22 contains a
plurality of longitudinally extending grooves 42 which form air
passageways as will be explained hereinafter. As can be seen in
cross-sectional view in FIG. 3, three groves 42 are illustrated,
each spaced 120.degree. apart. The invention can be designed with
more or less than three grooves as well. The grooves 42 extend from
an upwardly facing interior shoulder 44 formed at the top surface
of the upper coupling section 22 to the flange 28 and terminate at
the bottom surface 34.
A funnel 46 forms an upward extension of the upper coupling section
22 and is joined thereto at the interior shoulder 44. The funnel 46
has an outer diameter equal to the cylindrical member 20, and an
inner diameter equal slightly greater than the interior wall 38 at
the junction with the upper coupling section. The funnel then
flares outwardly to a port 52 into which containers such as the
inverted bottle 14 are inserted.
The lower coupling section 24 contains an interior wall surface 62
which extends from the flange bottom surface 34 to a generally
circular opening 64. A plurality of inwardly extending lugs 66,
which can be seen in FIG. 4, extend inwardly into the opening 64.
The lugs 66 are spaced 120.degree. apart.
The lugs 66 enable the upright bottle 16 to be inserted with its
opening positioned into the lower coupling section 24. A tight fit
is formed between the bottle and the coupling section as the lugs
66 lock onto the bottle serrations and the mouth of the upright
bottle 16 is secured to the bottom surface 34 of the flange 28.
Typically, catsup bottles and the like of different sizes and
configurations have identically sized mouths; therefore, the
coupling section 24 will fit the usual commercial bottle regardless
of size. Occasionally there is an exception in which event the
coupling section can be designed for each different size bottle
mouth.
The mouth 74 of the inverted bottle 14, from which the fluid is
transferred defines an aperture 72. As illustrated in FIG. 2 the
mouth 74 is positioned adjacent the top flange surface 36. An
enlarged serration 76 on the bottle rests adjacent the interior
shoulder 44 and prevents the inverted bottle 14 from wobbling when
positioned in the funnel 46. The funnel 46 of the coupling device
enables bottles of different sizes to be inserted into the port 52.
It is only necessary that the serration 76 of the inverted bottle
14 rest against the interior shoulder 44.
The bottle aperture 72 should have an opening less than the opening
of the flange 28 so that when fluid is transferred from the
inverted bottle 14, no hanging up of the fluid occurs adjacent the
top surface 36 of the flange 28. The fluid is transferred from the
inverted bottle 14 to the upright bottle 16 through the opening in
the flange 28. Air which is displaced in the bottle 16 can move
through grooves 42 enabling a constant relatively rapid flow of
fluid from the inverted bottle 14. When the upright bottle 16 is
full, the inverted bottle removed from the coupling section and the
full bottle 16 is then twisted so that it is free of the lugs 66
and ready for use.
