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.
- a piercing member is mounted on a shaft which also carries a valve member.
- part of the shaft may be exposed to the exterior ambient conditions when the tap is not in use. This can clearly lead to unhygienic conditions.
- EP-A-0046754 European Patent Application No. 80.901986.2 (Christine) though this is specifically concerned with a tap for a flexible bag and part of the shaft is always exposed to the atmosphere.
- 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 body adapted to be positioned in use adjacent the rupturable membrane of the container; an outlet in the body of the tap communicating with the inlet; membrane rupturing means disposed within the body of the tap; an axially movable shaft actuable externally of the body of the tap and remote from the inlet; and outlet sealing means is located downstream of the rupturing means and the shaft as disclosed in US-A-1763924.
- the invention is characterised in that the outlet is formed with a valve seat within the tap body; the outlet sealing means comprises a valve member having a valve stem connected to the shaft, the valve member being arranged to co-operate with the valve seat; and in that the membrane rupturing means comprises a membrane piercing head carried by the shaft adjacent the inlet, whereby, when the tap is located on the container and the shaft is moved axially towards the inlet, the piercing head breaks the membrane and the valve member is simultaneously lifted from the valve seal to open the 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 shaft, the piercing head and the outlet sealing means are integral.
- a resilient diaphragm may be connected to the shaft, whereby, when the tap is in use on a container, displacement of the resilient diaphragm acts to move the shaft to open the outlet and move the piercing head to break the membrane seal of the container.
- the diaphragm in its normal position may be stressed toward and over the outlet. In this arrangement it may be difficult to provide a long travel path for the piercing head.
- one end of the body portion of the tap accommodates a resilient diaphragm to which the shaft is attached.
- the resilience of the diaphragm retains the end of the shaft just out of contact with the membrane.
- the valve member also closes the fluid outlet. Depression of the diaphragm pushes the shaft through the membrane and removes the valve member from the valve seat of 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 straightline motion of the shaft results in almost straight line motion of the valve member. 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 member 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.
- 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 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 1 5 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 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 contents of 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.
