Abstract
A squeeze bottle is provided for dispensing a flowable liquid material. The bottle includes an axially extending squeezable container having a side wall and a base at one end of the side wall to define an interior chamber for housing the flowable liquid material. The container defines a neck that extends axially outwardly from an axially outer end of the container opposite the base. A cap is removably attachable to the neck, and includes a plate having at least one opening therethrough and in communication with the interior void of the container. The cap further includes at least two tips defining respective outlet channels in fluid communication with the plate opening to outlet at least two directed streams from the squeeze bottle to a desired food product.
Description
BACKGROUND OF THE INVENTION
The present invention relates generally to squeeze bottles, and in particular relates to a squeeze bottle for applying flowable liquid materials such as ketchup, mustard and like condiments to a food product in one pass.
Squeeze bottles for applying a condiment to a food product are well known. Generally, such a bottle includes a container made of a plastic or other easily compressible material that houses a given condiment. The container defines a neck portion disposed at one end of the container that is attached to an outlet assembly. A standard outlet assembly includes a cap that is threadedly connected to the neck of the container at one end, and has a single outlet tip that faces outwardly from the container at the other end. During use, the container is inverted and squeezed to dispense the condiment from the tip to a food product as a directed stream.
Conventional tips have a circular cross section and generally are sized to provide the user with flexibility to apply a desired amount of condiment to the food product. The softer squeezing of the container will yield a lower mass flow rate out of the tip. Accordingly, in order to accommodate those who wish to apply only a small amount of condiment to the food product, the tips are generally designed with a small cross section. Those who desire an additional amount of condiment can squeeze harder and, typically, make several passes at the food product. This can be a time consuming and often messy procedure. Further, one squeeze may not provide a sufficient amount of pressure to dispense condiment over the length of time necessary to conduct several passes, thereby necessitating multiple squeezes and a resulting non-uniform volume of dispensed condiment across the food product.
There is a need for an outlet assembly usable in combination with a conventional container that enables one to apply a sufficient and consistent amount of condiment to a food product with one pass.
BRIEF SUMMARY OF THE INVENTION
In accordance with one aspect of the invention, a cap for dispensing a flowable liquid material from an axially extending container is provided. The cap includes a substantially radially extending plate, having at least one opening extending therethrough, and a flange extending axially inwardly from the plate and configured to be connected to an axially outer end of the container. The cap further includes at least two outlets having axially outer ends presenting respective openings that extend axially inwardly through the at least one opening in the plate. The cap is configured to selectively place the openings in communication with the container.
The primary object of the present invention is to provide a bottle having multiple outlets for the application of a sufficient and consistent amount of flowable liquid material from the bottle.
Other objects and advantages of the present invention will become apparent to those skilled in the art upon a review of the following detailed description of the preferred embodiments and the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The preferred embodiments and best mode of the present invention will now be described in detail with reference being made to the drawings. Referring to
FIGS. 1 and 2
, a squeeze bottle
20
includes an axially extending container
22
having an elongated cylindrical side wall
24
extending axially along axis of extension A—A. A base
26
is disposed at the one axial end of the side wall
24
that seals the bottom of the container
22
. A neck
28
is integrally connected to the axially upper end of the container
22
, and is defined by a reduced diameter compared to that of side wall
24
. Neck
28
includes a threaded outer surface
30
. An internal void
32
is thus collectively defined by side wall
24
and base
26
for housing a volume of flowable liquid material. Examples of such flowable liquid material include condiments such as ketchup, mustard, mayonnaise, relish, or the like that may be poured into the neck
28
of container
22
.
Container
22
is made of a transparent or translucent plastic such as polypropylene or polyethylene to enable the user to gauge the amount and type of material in the container to determine when the container
22
is to be refilled. Alternatively, the plastic may be color coded to identify the type of material. The plastic is also preferably resilient so as to enable the user to squeeze the container
22
and thus provide an internal pressure suitable to force a directed stream of material out of the container and towards a desired food product. It should be understood that other dispensing methods can be utilized.
A cap
34
is removably connected to the neck
28
, and includes a cylindrical flange
36
that extends axially inwardly from the radially outer edge of a substantially radially extending plate
38
. The inner surface
42
of flange
36
is threaded and is configured to be removably connected to the container
22
by the threaded outer surface of neck
28
once the container
22
has been filled with the desired material. The radially outer surface
43
of flange
36
is preferably textured to enable a user to easily grip the cap
34
for attaching the cap to, and removing the cap from, container
22
. The axially outer surface of plate
38
is integrally connected to an outlet assembly
46
.
Outlet assembly
46
comprises an outlet housing
47
that extends axially outwardly from plate
38
. The housing
47
defines a housing interior void
49
that extends through plate
38
. The housing
47
is integrally connected at its axially outer end to three frusto-conical tip members
48
whose large ends extend from housing
47
such that the tips
48
extend axially outwardly therefrom. In particular, the tips are aligned in a direction B—B that extends transverse to axis of extension A—A. Each tip
48
defines an interior outlet channel
50
having an outlet
52
to the ambient environment at its axially outer end. Each channel
50
has an open inlet that is in fluid communication with void
49
, thereby placing each channel
50
in fluid communication with the void
32
of container
22
. When the user inverts the container
22
containing a flowable liquid material and directs the tips
48
at a food product and applies a squeezing pressure to container
22
, the material will be forced through outlet channels
50
and dispensed as three separate directed streams.
During operation, the container
22
is squeezed and is passed along the food product in a direction along lateral axis C—C that is normal to both axes A—A and B—B. Operating the bottle
20
in such a manner enables the material to be dispensed as three separate streams that are applied uniformly across the food product. The three streams enable a greater volume of material to be applied than was possible using a conventional single-tipped outlet. Accordingly, the need to make multiple passes with the container in order to deliver an adequate amount of a condiment to a food product is greatly reduced or eliminated by the present invention. Because each tip
48
has the same cross section and receives the condiment at generally the same mass flow rate, the condiment being dispensed from cap
34
will be applied more uniformly across the food product in contrast to previous methods whereby flow rates typically vary with each successive pass across the food product. Accordingly, the need to subsequently spread the dispensed condiment across the food product in a later step is also eliminated.
While the multiple tip design of the present invention enables a user to dispense a greater volume of material, the relatively small and circular cross section of each outlet
52
also allows the user to reduce the volume of dispensed material by controlling the amount of squeezing pressure applied to the container
22
. The outlets
52
can have varying size cross sections to correspondingly vary the mass flow rate of the dispensed condiment. Accordingly, a sandwich maker could choose from one of several caps having varying outlet cross-sections depending on the volume of condiment that is to be applied to a given food product. A cap (not shown) could further be provided to selectively seal one or more of the tips
48
if desired.
While the cap
34
includes three tips
48
in accordance with the preferred embodiment, it should be appreciated the present invention is intended to encompass a bottle cap having any number of tips (and corresponding outlets) greater than one tip to provide the advantages described above. The present invention further recognizes that the cap need not be used in combination with a squeeze bottle, but instead may be used in combination with any suitable container that houses a flowable liquid material that is to be expelled as a directed stream (or plurality of directed streams). It should be further appreciated that the present invention is related to a container having multiple outlets extending through the container and, accordingly, is not to be limited to the cap
34
illustrated and described herein. For example, the present invention is also intended to cover a cap
34
having more than one aperture extending directly through the plate
34
to provide an outlet from the container
22
. These apertures can be connected directly to a dedicated tip that extends axially outwardly directly from the plate
34
rather than through the outlet housing
47
described above.
Referring now to
FIG. 3
, an alternate embodiment is illustrated having reference numerals corresponding to like elements of
FIGS. 1 and 2
incremented by
100
for the purposes of clarity and convenience. In particular, one of the tips has been removed from the cap to produce a cap
134
having a pair of tips
148
extending outwardly from the outlet housing
147
along the direction of axis B—B as described above. Accordingly, during operation, a pair of directed streams of material are emitted at a food product, thereby reducing or eliminating the need to make multiple passes. It should be appreciated that the decision to employ a cap having two or three tips may depend largely on the type of material to be applied, it being appreciated that material that is generally applied more sparingly would be better suited for the dual-outlet cap
134
as opposed to the triple-outlet cap
34
, depending on the cross-sectional areas of the respective outlets. In addition, the size and shape of the food product may dictate the number of tips
148
to be used. For instance, a larger, more round food product, such as a hamburger, may be better suited for a wider three-tip design, while more narrow food, such as a hotdog, may benefit from a two-tip design.
Referring now to
FIG. 4
, an alternate embodiment is illustrated having reference numerals corresponding to like elements of
FIG. 3
incremented by
100
for the purposes of clarity and convenience. This embodiment recognizes that the multi-tip design of the present invention may allow a user to simultaneously dispense more than one condiment from a single container. Accordingly, squeeze bottle
220
includes a divider in the form of a wall
231
extending laterally across the container
222
along axis C—C (not shown in
FIG. 4
) and axially from the upper end of the neck
228
to the base of the container
222
(not shown in FIG.
4
). Wall
231
is positioned so as to bisect the internal volume within container
222
to form first and second chambers
232
and
232
′, respectively, that have equal volume and are fluid-tight with respect to each other. Chambers
232
and
232
′ are thus configured to contain different materials that may be simultaneously delivered to a given food product. A cap (not shown) can be provided to selectively seal one or more of the tips
248
and
248
′ if desired.
The cap
234
includes a corresponding dividing wall
233
that extends along axis C—C and axially outwardly from plate
238
. Wall
233
bisects the outlet assembly
246
to form a pair of internal chambers in the outlet housings
247
and
247
′ that define respective internal chambers
249
and
249
′ that are of equal volume and are fluid-tight with respect to each other. Tips
248
and
248
′ extend axially outwardly from housings
247
and
247
′ and define respective outlet channels
250
and
250
′ that are in fluid communication with chambers
249
and
249
′, respectively. Tips
248
and
248
′ are aligned in a direction along axis B—B as described above. A gauge (not shown) can be provided to the user for determining the proper alignment of walls
231
and
233
when attaching the cap
234
to the container
222
. For instance, markings can be present on the outer surfaces of cap
234
and container
222
that, when aligned, will indicate the proper alignment of dividers
231
and
233
. Preferably, threaded surfaces
230
and
242
have a large pitch to prevent the edges of dividers
231
and
233
from rubbing against each other and wearing when the cap
234
is removed from, and attached to, the container
222
. A gasket (not shown) can be disposed on the mating edges of dividers
231
and
233
to seal the chambers
232
and
249
, and
232
′ and
249
′ and protect the dividers.
During operation, when a user attaches cap
234
to container
222
, walls
231
and
233
become aligned thereby placing outlet channels
249
and
249
′ in fluid communication with channels
232
and
232
′, respectively. A first condiment such as ketchup is disposed in chamber
232
, while a second condiment such as mustard is disposed in chamber
232
′. The user may thus simultaneously dispense both condiments in equal amounts using only one application of one squeeze bottle. In particular, the first condiment in chamber
232
flows only into chamber
249
, and subsequently through the outlet channel
250
, while the second condiment in chamber
232
′ flows only into chamber
249
′ and subsequently through the outlet channel
250
′.
In some instances, it may be desirable to dispense a greater volume of one condiment than the other if, for example, one desires more ketchup than mustard. Accordingly, the embodiment illustrated in
FIG. 4
can be modified to enable one to dispense more volume of one condiment than the other per pass. For example, the cross-sectional area of one of the outlets, such as outlet
252
, can be enlarged to dispense a higher volume of condiment than the other outlet
252
′. In order to prevent chamber
232
from becoming depleted long before the other due to the greater mass flow rate of dispensed condiment, the dividers
231
and
233
can be repositioned off-center with respect to axis A—A to define chambers
232
and
232
′, and chambers
249
and
249
′, having volumetric ratios corresponding to the ratio of respective cross-sectional areas of outlets
252
and
252
′ and the resulting mass flow rates.
Alternatively, instead of altering the position of Walls
231
and
233
in a two-tip design, a three-tip design such as that illustrated in
FIG. 1
can be divided in a manner described above such that one-third of the container (and one corresponding tip) is dedicated to one condiment while the remaining two-thirds of the container (and two corresponding tips) are dedicated to the second condiment. Further, a container can include two dividers to define three chambers, each in fluid-tight communication with a dedicated tip, for simultaneously dispensing three condiments.
Referring now to
FIG. 5
, an alternate embodiment of the invention is illustrated having reference numerals corresponding to like elements of the previous embodiment incremented by
100
for the purposes of clarity and convenience. In particular, cap
334
includes an outlet assembly
346
defining an outlet housing
347
that has a substantially rectangular cross-section extending axially outwardly from the plate
338
. The outlet housing
347
terminates at its axially outer end at a plurality of tips
348
that extend along axis B—B. The outlets
352
of tips
348
have elongated, substantially rectangular, cross-sections whose elongated dimension D extends along axis B—B, and whose minor dimension C extends laterally (perpendicular to axis B—B). Accordingly, the bottle
320
will emit a more diffuse directed stream of condiment when applying the condiment to food product by moving the bottle laterally with respect to axis B—B, as described above. While three elongated tips
348
are illustrated, it should be appreciated that two or more such tips could be implemented in accordance with the present invention. Further, while the outlets have a rectangular cross-section, it should be appreciated that any elongated cross section, such as an oval, can also be utilized.
The elongated tips
348
can be modified as illustrated in
FIG. 6
, whereby a plate
349
covers the axially outer end of each outlet
348
. Two apertures
354
having a circular cross section extend through plate
349
and provide multiple directed streams of condiment for each elongated tip. It should be further appreciated that any number of such apertures
354
(one or more) can be utilized.
Referring to
FIGS. 7 and 8
, an alternate embodiment is illustrated having reference numerals corresponding to like elements of
FIG. 5
incremented by
100
for the purposes of clarity and convenience. The cap
434
of this embodiment can be used with one of the containers described above such as container
22
. In this embodiment, the outlet housing
447
extends outwardly from the plate
438
along a direction B—B that extends transverse to axis of extension A—A. The housing
447
includes a housing interior void
449
that extends through the plate
438
. Material from the container to which the cap
434
is attached enters the interior void
449
and then passes evenly through the tips
448
to the outlets
452
for placement on a food product.
The above detailed description of the present invention is given for explanatory purposes. It will be apparent to those skilled in the art that numerous changes and modifications can be made without departing from the scope of the invention. Accordingly, the whole of the foregoing description is to be construed in an illustrative and not a limitative sense, the scope of the invention being defined solely by the appended claims.
