Definitions

  • This invention relates to improvements in or relating to taps and refers particularly, though not exclusively, to improvements in or relating to taps for use with the well-known "bag-in-the-box" containers for beverages.
  • the present invention has as another object the provision of a tap which is of relatively simple production, is relatively easily manufactured and assembled, and provides for sufficient oxygen barrier.
  • a tap having a body and a spigot, said body being adapted to receive said spigot, said body having an inner end closed by a sealing means, said spigot having an inner end adapted to pierce or remove in total or in part said sealing means upon relative movement of said spigot and said body.
  • the invention also provides a tap including a body having an internal opening, a lever adapted to close said opening, a removable or frangible seal across said lever to seal said opening, an outlet from said tap, said lever having means attached thereto by which said opening can be closed When said lever is in a first position and opened when said lever is in a second position; movement of said lever from said first to said second position causing removal of said removable or frangible diaphragm.
  • a container 10 which is an outer container of suitable material such as plastics or cardboard and which is used to hold a fluid which, preferably, is contained within a separate, flexible and collapsible bag within the container 10.
  • a tap 12 Fitted to the container 10 is a tap 12 which has a flange 14 to retain the tap 12 in position in relation to the container 10.
  • the tap 12 is clearly seen in Figures 2 to 5 inclusive and comprises a body 16 the outer end of which comprises the flange 14. Extending axially outwardly from the flange 14 is a spigot receiving part 18 which is open at each end. The inner end 20 of the spigot receiving part 18 is angled as is shown in the drawings. The inner end 20 is closed by a rupturable or peelable-diaphragm or seal 22 which is secured to the inner end 20 by means of gluing, welding, or heat application.
  • the spigot receiving part 18 also has an outlet 24 so that contents can be dispensed as will be understood hereafter.
  • the entire body 16 is adapted to be received within a plug 26 which is located inside the container 10 and which is attached thereto by means of a groove 28.
  • the inner end of the plug 26 is secured to a bag 30 located within the container 10 and in which bag 30 the contents are held.
  • the bag 30 is collapsible so that the contents of the bag 30 are not subjected to contact with oxygen or air during normal usage.
  • a spigot 32 Located within the spigot receiving part 18 is a spigot 32. At the outer end of the spigot 32 there are provided seals 34 locating in corresponding grooves in the spigot receiving part 18 so that the spigot once inserted cannot be unwantedly removed and to provide for a fluid-seal between the spigot 32 and the spigot receiving part 18.
  • the spigot 32 has an inner end 36 which corresponds in shape and angle to the inner end 20 of spigot receiving part 18.
  • the inner end 36 is adapted, in use, to tear, puncture or lift the seal 22 off the inner end 20 when the spigot is rotated about its longitudinal axis as will be understood by the following description.
  • the spigot has an opening 38 which is designed to co-operate with the outlet 24 when the spigot is in the ON position (see Figure 5) to allow the contents of the bag 30 to be dispensed.
  • a handle 40 Integral with the spigot 32 is a handle 40 which closes the outer end of the spigot and also provides a means by which a user can operate the tap.
  • the handle 40 has an opening 42 therein to enable the contents of the bag 30 to be properly dispensed when the opening 42 is in radial alignment with the opening 38 in the spigot 32.
  • the handle 40 extends axially inwardly in parallel with the spigot so as to surround the spigot receiving part 18.
  • the handle skirt 44 has a radially inwardly directed projection 46 which, when the tap is in the OFF position, closes the outlet 24.
  • the projection not only provides for a proper closing of the outlet 24 but would also tend to prevent any quantity of fluid in the outlet 24 from forming a drip which would tend to come from the handle at a later date.
  • the operation of the tap 12 is such that it is in the OFF position as shown in Figure 2.
  • the inner end 36 of the spigot 32 moves so as to force the seal 22 away from the inner end 20 of spigot receiving part 18. This can be done in the manner illustrated by breaking the glue, weld or the heat-securing or, alternatively, by actually tearing or rupturing the seal 22.
  • the handle 40 has been rotated through 180 degrees the removal of the seal 22 to allow fluid to flow is complete.
  • the opening 38 in the spigot 32 is in alignment with the outlet 34 so that the fluid can travel through the hollow interior of the spigot 32, through the opening 38, and out via the outlet 24.
  • the projection 46 can extend around a substantial portion of the inner surface of the skirt 44 so that it completely blocks the outlet 24 except when the tap is in the ON position when the opening 42 is adjacent the outlet 24.
  • the tap 112 operates in exactly the same way as the tap 12 of Figures 1 to 5 and has a flange 114, a body 116, a spigot receiving part 118, an inner end of the spigot receiving part 120, a seal 122 across the inner end 120 at the same or a similar angle, but has an outlet 124 in the form of a hole in the spigot receiving part 118.
  • a spigot 132 Mounted within the spigot receiving part 118 is a spigot 132 having an angled inner end 136 on a similar angle to the inner end 120 of the spigot receiving part 118.
  • the spigot 132 has an opening 138 which is adapted to align with the outlet 124 when the tap is in the ON position.
  • the outer end of the spigot 132 is closed by a handle 140 which is provided with a finger grip 148.
  • the inner end 136 of the spigot 132 is of smaller radial extent due to the spigot receiving part 118 having a flange 150.
  • the flange 150 is provided to allow for easier attachment of the seal 122 to the inner end 120 of the spigot receiving part 118.
  • the operation of the spigot 132, its inner end 136 and the seal 122 is exactly as was described for Figures 1 to 5.
  • the spigot 132 has a portion 152 which is used to also close the outlet 124 when in the OFF position.
  • the portion 152 wipes over the hole of outlet 124 to prevent any possible drips passing through and out of the tap. It also provides for further oxygen protection.
  • a tap 212 which has a flange 214, a body 216, a spigot receiving part 218, an inner end 220 of the spigot receiving part, a seal 222 across the inner end 220, an outlet 224, a spigot 232, the inner end 236 of the spigot being arranged as per previous embodiments, an opening 238, a handle 240 having a grip 248, and a wipe clean portion 252.
  • the main difference of this embodiment over the previous embodiments is that the inner end 236 of the spigot 232 has an opening 254 as was described as an alternative or additional feature for the embodiments of Figures 1 to 5.
  • the seal 222 comprises a diaphragm 256 which is similar to the seal 222 of the previous two embodiments.
  • the diaphragm 256 is mounted on a disc 258 which is integral with the spigot receiving part 218 and blocks the inner end 220 of that spigot receiving part 218.
  • the disc is provided with a weakness portion 260 for much of its circumference with the only part of the disc 258 not having the weakness portion 260 being that at the top of the spigot receiving part 218.
  • the disc 258 is provided so that upon the spigot being turned it will force the disc out by virtue of the weakness portion 260.
  • the part of the disc 258 not having the weakness portion will remain attached to the inner end 220 of the spigot receiving part 218 in the form of a hinge 257. This will also push the diaphragm 256 away from the inner end 220 of the spigot receiving part 218.
  • the strength of the material of the disc 258 will tend to hold it in that position so that it would not foul or block the opening to the hollow interior of the spigot 232. This would tend to increase the capacity of fluid flow into the spigot 232 and thus out through the opening 238 and the outlet 234.
  • the weakness portion may be provided by having material of far less thickness, perforations, or as otherwise may be suitable.
  • Figures 14 and 15 show a variation on the above where the seal has been located inside the flange at the inner end of the spigot receiving part. This allows for the outer edges of the seal to be not in contact with the contents of the container.
  • the seal is a laminate, it has been found that certain liquids (e.g. wine) contain certain acids that corrode the adhesive used to create the laminate and/or one of the layers of the laminate. By using this form, the contents are in contact with one surface only and not the edge of the seal.
  • a tap 310 which comprises a body 312, a handle 314, and an operating lever 316.
  • the body 312 is generally cylindrical and has an inner end 318 which has external ribs 320 designed to hold the tap 310 in a sleeve (not shown).
  • the body 312 also has a radially extending flange 322 which is also designed to co-operate with the sleeve (not shown) to provide a limit for movement. Extending radially inwardly is an inner flange 324 which extends into the hollow interior of the body 312.
  • the body 312 At the outer end 326 of the body 312 there are provided two radially extending ribs 328, 330 which are designed to co-operate with the handle 314 to retain the handle 314 in position.
  • the first rib 328 also protects the handle 314 from being removed from the body 312 accidentally during use of the tap.
  • the body is preferably made of a relatively rigid plastics material so as to provide for necessary strength.
  • the handle 314 locates around the outer end 326 of body 312 and locates between ribs 328, 330 and over rib 330 so as to prevent unwanted removal of the handle 314 from the body 312.
  • the handle like the body, is a one-piece plastics moulding although the handle is made of a relatively flexible material.
  • the external skirt 332 locates as is explained above over the outer end 326 of the body and covers the end of body 312 by means of the flexible diaphragm portion 334.
  • the diaphragm portion is off-set in its lower areas to provide a finger receiving portion 336.
  • Axially located in the handle is a tapered socket 338 which is adapted to receive the longitudinally extending member of the lever.
  • the handle in its upper portion has a flexible bulb-like "spring" 340 which is relatively resilient. Upon operation of the handle the spring is compressed and provides the necessary resilience to force the handle to return to the position shown in Figure 20.
  • a closure member 342 Attached to the handle 314 is a closure member 342.
  • This closure member is in the form of a cylinder and is integral with the socket 338 at its upper portion.
  • the closure member 342 is designed to contact the bore wall of the body 312 to close an outlet 344.
  • the socket 338 receives the longitudinally extending member 346 of the lever 316.
  • the member 346 is retained within the socket in the manner of a tightly sealed fit.
  • the lever 316 also includes a closing member 348 which is perpendicular to and integral with the longitudinal member 346.
  • the closing member 348 is integral with the inner flange 324 although there are provided a number of perforations 350 so that the closing member 348 may be separated from the inner flange 324.
  • the closing member is hinged to the inner flange 324 by means of a hinge 352.
  • a removable or frangible seal 354 Located on the innermost surface of the closing member 348 of lever 316 is a removable or frangible seal 354.
  • This seal is oxygen impervious and is attached to the inner surface of closing member 348 and inner flange 324 by means of glue, welding, heat-sealing, or any other suitable attachment.
  • the seal 354 provides for an oxygen barrier to prevent the ingress of oxygen into the containers of the bag (not shown).
  • Figures 22 to 25 show a variation which operates in exactly the same way as in the Figures 18 to 21 except that the closure member 342 is not in the form of a longitudinally extending cylinder but in the form of a vertically extending cylinder 343.
  • the closure member can have an extended portion 345 in its lower end 347 which would pass into the outlet 344 so as to prevent the retention of any fluid therein which may cause a drip at a later stage. This is the only difference between the two.
  • Figures 26 and 27 show a variation of the embodiment of Figures 22 to 25 wherein the extension on the lower portion of the closure member 342 is removed.
  • the handle for the two variations may be made more simple such that the handle is in the form of a dish and has an outwardly extending tab into the dish to provide for the finger grip.
  • the handle could be made in the same way as for Figures 18 to 21.
  • the handle of the embodiment of Figures 18 to 21 could be made in the way shown in Figures 23 and 24 rather than is shown in Figures 19 and 20.
  • a cap to be placed over the skirt of the handle and which, in the case of the handle of Figures 18 to 20, would have a projection extending into the finger receiving portion 336 and, in the case of Figures 22 to 26, would have a socket for receiving the outer end of the socket 338. This cap would be used while the tap was in transit to prevent accidental or unwanted operation.
  • a tap 412 having a body 416 with a flange 414 at one end.
  • the tap is fitted to a container (not shown) by the flange for dispensing of liquid.
  • Extending axially outwardly from the flange 414 is a spigot receiving part 418 which is open at one end.
  • the inner end 420 of the spigot receiving part 418 is angled as is shown in the drawings.
  • the inner end 420 is closed by a rupturable diaphragm 422 which is integrally moulded with the spigot receiving part 418.
  • the diaphragm 422 has a Weakness portion 425 for much of its circumference with the only part of the diaphragm not having the weakness portion being that at the top of the spigot receiving part 418.
  • a seal 426 is secured to the inner end 420 by means of gluing, welding or heat welding.
  • a spigot 432 Located within the spigot receiving part 418 is a spigot 432. At the outer end of the spigot 432 there are provided seals 434 locating in corresponding grooves in the spigot receiving'part 418 so that the spigot once inserted cannot be unwantedly removed and to provide for a fluid-seal between the spigot 432 and the spigot receiving part 418.
  • the spigot 432 has an inner end 436 which has a cam 450 thereon.
  • the cam 450 is adapted, in use, to rupture and lift the diaphragm 422 off the inner end 420 when the spigot is rotated about its longitudinal axis as will be understood by-the following description.
  • the spigot has an opening (not shown) which is designed to co-operate with the outlet 424 when the spigot is in the ON position to allow the contents of the container to be dispensed.
  • Integral with the spigot 432 is a handle 440 which closes the outer end of the spigot and also provides a means by which a user can operate the tap.
  • the operation of the tap is such that it is in the OFF position as shown in the drawing.
  • the cam 450 will force the diaphragm 422 outwardly and rupture both diaphragm 422 and seal 426 along the weakened portion 425.
  • the diaphragm will be lifted and pivotted upwardly to provide an unobstructed passage of liquid through the tap.
  • the tap 512 operates in exactly the same way as the tap 412 of Figure 28 and has a flange 514, a body 516, a spigot receiving part 518, an inner end of the spigot receiving part 520, and a diaphragm 522 across the inner end 520.
