The present invention provides a disposable assembly for use with a reusable urn or vessel for dispensing fluids and more particularly a disposable assembly having a pouch, a fitment on the pouch, a tubing adapter and a tubing that are assembled and inserted into a fluid chamber of a reusable urn for dispensing beverages for human consumption.
Self-service dispensing containers have become very popular in restaurant settings for storing and dispensing liquid beverages. Such containers typically include a reusable urn with a dispensing valve at the bottom for gravitational dispensing of product therein. In some instances the urn is fitted with a disposable assembly having a pouch, a fitment attached to the pouch, and a tubing attached to the fitment. The pouch is placed inside the urn and the tubing is passed through the valve and liquid is placed within the pouch so that it does not contact any portion of the reusable urn or valve. Thus, the container and valve remain clean for longer periods of time and can be more easily and quickly cleaned during normal cleaning procedures.
To understand the present invention, it will not be described by way of example, with reference to the accompanying drawings in which:
a,b are cross-sectional views of a faucet of the present invention;
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
Referring now in detail to the Figures, and initially to
The disposable assembly forms a liner for the containing vessel 12 and dispensing valve 20 such that liquid does not contact the internal components of either the containing vessel 12 or dispensing valve 20.
The aperture 48 is formed with a punch that removes a portion of the wall to define the aperture 48. The aperture 48 is dimensioned to allow the passage of the cylindrical portion 50 but not the flange. The spout 16 is connected to the first panel 36 by heat sealing or other suitable method consistent with the use of the container. As is best shown in
The first and second panels 36,46 of the prior art pouch are generally made of a flexible plastic material which is capable of being heat sealed together. The material utilized should have a melt softening temperature greater than 175° F. and can be a linear low density polyethylene, polyolefins, polypropylene, polyvinyl chloride, polyester, nylon, and the like, including co-extruded and laminated materials, which exhibit similar characteristics may be used.
During manufacture of the pouch 14, the first and second panels 36,46 are heat sealed together adjacent their respective bottoms 40 and opposed first and second sides 42,44 to form a pouch 14 having three seal areas 56,58,60 and a first opening 62 to an interior pocket 64 between the connected first and second panels 36,46. When sealed together, the bottoms 40 of the panels form a sealed second end 66 of the pouch, and the opposed sides 42,44 of the panels form opposed sealed first and second sides 68,70 of the pouch 14, respectively. The tops of the panels form an open first end 72 of the pouch. Both of the opposing side seals 56,58 extend from the first end 72 of the pouch to the second end 66 of the pouch, and the bottom seal 60 extends about a length of the second end 66 of the pouch. A first end 74 of the bottom seal 60 is adjacent the first of the opposing side seals 56 and a second end 76 of the bottom seal 60 is adjacent a second of the opposing side seals 58. As such, the first opening 62 of the pouch extends horizontally from substantially the first seal area 56 to substantially the second seal area 58 adjacent the top or first end 72 of the pouch, and provides an entrance to the interior pocket 64. As seen in
As is shown in
The prior art dispensing valve 20 is connected to the containing vessel 12 at the second opening 26 of the containing vessel as illustrated in
Accordingly, one of the initial steps required to set up the system even before the pouch 14 is placed within the interior cavity 22 of the containing vessel 12 is to attach the dispensing tube 18 via the fitment 82 thereof to the spout 16. Next, if the dispensing valve 20 is not already attached to the containing vessel 12, the dispensing valve 20 must be connected at the second opening 26 of the containing vessel such that the second opening 26 and the channel 86 through the dispensing valve are in open communication. Once the dispensing valve 20 is in place, the pouch 14 is inserted into the interior cavity 22 of the containing vessel 12.
These prior art dispensing systems are more fully set forth in the commonly owned U.S. Pat. No. 6,116,467 which is incorporated herein by reference in its entirety and made a part hereof. Due to problems encountered in using the disposable insert assemblies described above with urns and vessels having exit ports in close proximity to a bottom wall of the urn, a new approach was needed for the disposable assembly.
More specifically,
To this end,
The fitment 204 has a generally circular flange 214 having a planar surface 216 and a generally centrally disposed annular wall 215 extending axially away from the planar surface 216 defining a fluid passage 218 of the annular wall and circumjacent a through a hole (not shown) of the fitment 204. The circular flange of the fitment is attached to the outer planar surface 210 of the pouch with the through hole 212 of the pouch and the through hole of the fitment being in registration to allow for fluid communication between the contents of the pouch and an exterior of the pouch.
The tubing adapter 206 as shown in
The second cylindrical wall 232 is inserted into the annular wall 215 of the fitment 204 and the notch 248 engages a structure (not shown) on an inner surface of the annular wall 215 to fixedly attach the tubing adapter 206 to the fitment 204.
As shown in
In a preferred form of the invention, the angle of dispensing should be from about 45° to about 100°, more preferably from 55° to about 90° and most preferably from 65° to about 90°. To this end,
In another preferred form of the invention shown in
In another preferred from of the invention shown in
It has been observed by users of tube 18 of a monolayer of SEBS, that it tends to kink upon insertion into the channel 86 of the dispensing valve 20. In a preferred form of the invention, the tubing resists kinking during insertion into the dispensing valve 20 and has an increased inner diameter of greater than 7 mm while maintaining an 11 mm outer diameter. The increased inner diameter allows for higher flow rates through the tubing when compared with tubings of lesser diameter and allows for dispensing of fluids with a broader range of viscosities when compared to smaller inner diameter tubings.
The outer layer 272 is preferably an olefin material and more preferably an ethylene terpolymer and even more preferably an ethylene and alpha-olefin copolymer. As used herein, the term “interpolymer” includes copolymers, terpolymers either random, stereoregular (such as isotactic, syndiotactic) or block.
Suitable ethylene and α-olefin interpolymers preferably have a density, as measured by ASTM D-792 of less than about 0.915 g/cc and are commonly referred to as very low density polyethylene (VLDPE), linear-low density polyethylene (LLDPE) ultra low density ethylene (ULDPE) and the like. The α-olefin should have from 3-17 carbons, more preferably from 4-12 and most preferably 4-8 carbons. In a preferred form of the invention, the ethylene and α-olefin copolymers are obtained using single site catalysts. Suitable single site catalyst systems, among others, are those disclosed in U.S. Pat. Nos. 5,783,638 and 5,272,236. Suitable ethylene and α-olefin copolymers include those sold by Dow Chemical Company under the AFFINITY tradename, Dupont-Dow under the ENGAGE tradename and Exxon under the EXACT and PLASTOMER tradenames.
In a preferred form of the invention, the ratio of thicknesses of the outer layer 272 to the inner layer 274 is from about 1:4 to about 1:2 and more preferably from about 1:3 to about 1:2.5.
It is contemplated that the tubing can have a portion that is compressed into an accordion shape that is capable of flexing into discrete positions much like flex straw. This will provide of ease of insertion of the tubing into the faucet.
Four different faucets shown in
The flow rate results of these eight tested assemblies compared favorably with the prior art device shown in
The results shown in the Table below also compare favorably with a prior art urn having a Tomlinson valve with a 90° dispensing angle and with no disposable assembly wherein the contained fluid comes into direct contact with the walls of the urn and an interior fluid conduit of the Tomlinson valve. This prior art container was found to have a flow rate of 5.2 oz/sec.
Each faucet assembly was mounted to a water containing urn and the time was recorded to dispense 16 oz of water. Each faucet was tested over 20 intervals, the time was averaged and the flow rate per ounce was calculated. The results are shown below in the following table. Overall, the Mini disposable of the present invention outperformed the Large, prior art, disposable assembly. Faucets 3 and 4 with a R of 1.625 inches outperformed the smaller radius of 1.495 inches. This is a surprising result as the Mini disposable is far smaller and weighs considerably less than the prior art disposable assembly shown in
While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention, and the scope of protection is only limited by the scope of the accompanying Claims.
