Definitions

  • This invention relates to taps and valves particularly for use with flexible containers for liquids.
  • the tap proposed by Malpas in patent 402,978 is inserted into a socket mounted on a wall of the flexible container.
  • This socket incorporates a portion of the container wall to form a rupturable membrane which is broken when the tap is inserted into the socket.
  • An improved construction of the flexible container and socket is disclosed in Australian patent application 47367/79. Because the taps have to be assembled into the socket of the container by the end user there has been consumer resistance to the use of taps of this kind. However it is also important to delay the rupturing of the membrane sealing the container until the contents are to be dispensed. This requirement is important where the contents of the flexible container are to be kept airtight to avoid deterioration by oxidation.
  • closure valve is distant from the outlet and because liquid can accumulate between the valve and the outlet, these taps are susceptible to dripping, which is unacceptable to consumers.
  • the present invention provides a tap adapted for use with a container having a rupturable membrane seal, the tap comprising a body; an inlet in the said body adapted to be positioned in use adjacent the rupturable membrane of the container; an outlet in the said body of the tap communicating with the said inlet; means sealing the said outlet; membrane rupturing means disposed within the said body of the tap; actuation means, actuatable and preferably accessible externally of the said body of the tap and remote from the said inlet, the said actuation means, when the tap is located on the container, being adapted to simultaneously move the said membrane rupturing means to a position adjacent the said inlet to break the said membrane and to move the said outlet sealing means to open the said outlet.
  • the present invention thus provides a tap which can be placed in position on the container without rupturing the membrane seal. When it is desired to dispense the contents of the container the membrane is ruptured by the first operation of the tap.
  • the tap of this invention can take several forms. Ideally the actuation means, the membrane rupturing means and the outlet sealing means are integral.
  • the said actuating means comprises a resilient diaphragm which seals the said outlet and is connected to the said membrane rupturing means, displacement of the said resilient diaphragm acting to open the said outlet and move the said membrane rupturing means to break the said membrane seal of the container.
  • the diaphragm in its normal position is stressed toward and over the outlet. In this arrangement it is difficult to provide a long travel path for the rupturing means.
  • the said actuating means carries a membrane piercing shaft extending within the said tap body toward the said inlet and the said outlet sealing means comprises a valve having a valve stem connected either to the actuation means or the said membrane piercing shaft.
  • the actuating means is a resilient diaphragm.
  • one end of the body portion of the said tap accommodates a resilient diaphragm to which the said shaft is attached.
  • the resilience of the diaphragm retains the end of the said shaft just out of contact with the said membrane.
  • the valve seat also closes the fluid outlet. Depression of the diaphragm pushes the shaft through the membrane and removes the valve seat from the liquid outlet.
  • the diaphragm is preferably formed to include a resilient fold or concertina shape rather than a shallow dome.
  • One such diaphragm is prescribed in British patent 977,660.
  • valve stem extends in a nearly opposite direction to the shaft so that the strai g htline motion of the shaft results in almost straight line motion of the valve seat. It is possible for the shaft and valve stem to be offset but parallel and the outlet would then be disposed below the.diaphragm. Because the valve seat closes the outlet within the body portion the outlet can be exposed so that there is no possibility that dirt could accumulate in an outlet tube.
  • actuating means comprises an axially movable shaft extending within the said tap body the said shaft carrying a membrane piercing head adjacent the said inlet and a portion of the said shaft comprising a seal for the said outlet.
  • the first partial axial movement of the shaft may unseal the outlet so that only the first operation of the tap would require large axial movement to rupture the membrane seal.
  • Axial movement of the shaft may be provided by sliding or rotary movement a screw threaded shaft being preferred.
  • the present invention also provides a flexible walled liquid container having secured to a wall thereof a tap socket incorporating a rupturable membrane sealing the liquid contents thereof, a tap inserted and secured within the said socket the said tap being made according to one of the embodiments of this invention.
  • the tap as illustrated comprises a body section 11 having an inlet end 4 and an outlet 5. One end of the body section is closed by a resilient diaphragm 6.
  • the body section 11 is preferably composed of polypropylene and the preferred material for the diaphragm 6 is polyethyl vinyl acetate.
  • the diaphragm may be provided in any suitable form e.g. a concertina type resilient panel as long as the diaphragm is resilient, capable of large deformation and of subsequently resuming its normal shape under its own resilience.
  • the plunger 7 Disposed within the body section is the plunger 7 which is preferably formed from nylon. At one end 14 of the shaft it is connected to the diaphragm 6. This connection at the end 14 in this embodiment is a snap fit into a recessed boss on the inside face of the diaphragm 6.
  • the plunger 7 extends through a guide ring 15 within the body portion 11.
  • the plunger 7 carries at the end adjacent the inlet 4 a piercing spigot 8.
  • Extending rearwardly from the spigot 8 is a valve stem 9 and a valve 10 which seals a valve seat 17 provided on the inside of the outlet 5.
  • Figure 2 which shows the end view of the spigot 8 illustrates one preferred form.
  • Guide grooves 19 are provided on the inside of the tap body 11 and guide ribs 18 are provided on the spigot 8 and their interengagement assists in ensuring direct movement of the plunger 7 and the spigot 8 past the inlet end 4 of the body section 11.
  • Figure 3 shows the tap in use fitted in a collar 19 on the wall 12 of a flexible container.
  • the inlet 4 of the body section 11 abuts the membrane 13 which seals the container.
  • the piercing spigot 8 ruptures the membrane 13 and at the same time the valve closure 10 is withdrawn from the seating 17 of the outlet 5 thus allowing the fluid contentsof the container to be dispensed.
  • the diaphragm On removal of the deforming pressure from the diaphragm it resiliently springs back to its normal position.
  • the present invention provides a tap convenient for consumers to use which still enables the rupturing of the sealed container to be delayed until dispensing of the fluid contents is commenced.
