Abstract
Disclosed herein are a method of an apparatus for providing a vented closure (10) for a container having complementary non gas-tight features (52, 54) by which the closure may be removeably attached to close the container, by fitting a venting member (12) to form a liquid-tight, gas-venting seal between the closure and the container and provide a venting gas path from the container through the venting member to atmosphere via the complementary closure and container features; the venting member may replace or by-pass the existing sealing member in a closure.
Description
- This invention relates to a method of and apparatus for providing a vented closure for a container and it particularly relates to venting members for container closures.
- An known type of container closure is a cap having a none-gas tight screw thread fitting with the complimentary thread neck of a container and a seal in the cap to form a gas and liquid-tight seal with the container neck. Liquid containers can become over or under pressurised and the container damaged, such as by ballooning or crushing, depending on the liquid to be contained and the ambient temperatures. One solution is to make the container strong enough to resist such changes, another solution is to fit the container with a gas vent. The choice of solution is mainly an economic one, depending upon whether or not it is cheaper to make the container stronger or to fit a gas vent.
- Known gas vents for container require special closures and/or modified containers.
- According to one aspect of the present invention, a method of providing a vented closure for a container, the closure and container having complimentary none gas-tight features by which the closure may be removeaby attached to close the container, comprises fitting a venting member to form a liquid-tight, gas-venting seal between the closure and the container and provide a venting gas path from the container through the venting member to atmosphere via the complimentary closure and container features.
- According to another aspect of the present invention, a method of converting a sealed to a vented closure for a container, the closure and container having complimentary features by which the closure may be removeaby attached to close the container and a sealing member to form a fluid-tight seal between the closure and the container, comprises replacing or by-passing the sealing member with a venting member to form a liquid-tight, gas-venting seal between the closure and the container and provide a venting gas path from the container through the venting member to atmosphere via the complimentary closure and container features.
- No modification to either the closure or the container is required when using the method of the present invention.
- Also according to the present invention, in a venting closure for a container, the closure and container having complimentary, none gas-tight features by which the closure may be removeaby attached to the container, a venting member is shaped and dimensioned to fit as a liquid-tight, gas-venting seal between a given closure and container and, in use, provide a venting gas path from the container through the venting member to atmosphere via the complimentary closure and container features.
- The vented member may designed to replace or by-pass a sealing member, forming a fluid-tight seal between the closure and the container, and form a liquid-tight, gas-venting seal between the closure and the container.
- Thus, a liquid container can be provided with a gas vent according to the present invention simply and economically; no modification of the container or closure being required, simply the provision of a suitable venting member together with taking advantage of the potential gas flow path already present between the closure and container attachment features.
- In a preferred embodiment, the venting member is microporous; for example a microporous membrane.
- The advantages of the using microporous membranes for vented closures is that they work at zero differential pressures and are bidirectional; i.e. they vent gases in both directions, in and out of a container. The main disadvantage of such use of microporous membranes is that their operating efficiency is severely reduced when wetted by a liquid, such that the membrane hardly works at all.
- According to a further embodiment of the present invention, the complimentary closure and container features form an air-side labyrinth seal that, in use, acts to prevent passage of liquid to the venting member.
- According to another embodiment of the present invention and wherein the closure is a cap and the container has a neck, the cap and neck having the complimentary features, the venting member is an insert for the cap. Gas flow means may be provided between the insert and the cap.
- According to a still further embodiment of the present invention, the insert has a liquid-side capillary port that, in use, acts to permit passage of gas and prevent passage of liquid to the venting member. The capillary port is dimensioned so that the surface tension of a liquid to be contained in the container prevents that liquid from normally contacting the microporous membrane; this both improves membrane efficiency by preventing membrane wetting and protects the membrane from liquid-induced forces and loads that may occur during operational use of the filled container.
- The above and other features of the present invention are illustrated, by way of example, in the Drawings; wherein
- FIG. 1 is a cross-sectional view of a microporous membrane vented closure for a liquid container in accordance with the present invention;
- FIG. 2 is an exploded cross-sectional view of the closure of FIG. 1:
- FIG. 3 is a cross-sectional view of a container neck;
- FIG. 4 is a cross-sectional view of the closure of FIG. 1 screwed onto the neck of FIG. 3;
- FIG. 5 is a side elevation corresponding to FIG. 4; and,
- FIG. 6 is an enlarged detail of part of FIG. 4.
- As shown by the figures, a microporous membrane vented
closure 10 consists of a generallycircular insert 12 moulded from a suitable rigid plastics material, such as LDPE, to generally conform to the inner shape of a container cap14. Theinsert 12 has acentral aperture 16 with an air-side, surrounding, axially upwardly extending,cylindrical lip 18 and a radially extending liquid-side rim 20. Therim 20 has a liquid-side, surrounding, axially downwardly extending,cylindrical rib 22. Theaperture 16 is closed on the liquid-side by amicroporous membrane 24, for example of “GORTEX®”, that is bonded, such as by welding, within therib 22 to therim 20 to form a liquid seal therewith. - The
membrane 24 is protected on the liquid-side by a mouldedplastic cup 26, having cylindrical upper part the external diameter of which is an interference, liquid-tight fit within a liquid-side, axially extending, cylindrical,outer rib 30, that co-axially surroundsrib 22. Thecup 26 has an external, radially outwardly extending flange that acts as a stop against the rim ofrib 30, to control the depth of insertion of the cup upper part. - The
cup 26 has a hernispherically-shaped bottom part that is provided with acentral port 28; - the
port 28 is dimensioned so that it can act as a capillary port, using the surface tension of a liquid to be contained in the container act to prevent that liquid from normally entering the cup. -
Outer rib 30 is an integral part of and depends from a dishedcentral portion 32 of theinsert 12 that flares upwardly and outwardly fromlip 18 to acorrugated rim portion 34. Therim portion 34 has two concentricperipheral grooves integral sealing flange 40 that depends within thecontainer cap 14, and downwards, to accommodate therim 42 of acontainer neck 44. - The air-side, cap facing surface of
insert 12 is roughened and the dished central portion is provided withintegral ribs 46 extending radially to therim portion 34. - In use, and especially as shown by FIGS. 1, 4 and6, the vented
closure 10, comprisinginsert 12 withmembrane 24 andcup 26 is fitted within aconventional container cap 14 and the whole assembly is screwed onto theneck 44 of acontainer 48. - Gases within the
container 48 can vent - through the
microporous membrane 24, - within the insert
cylindrical lip 18, - though notches50 in the rim of
lip 18, - between the under-surface of
cap 14 and theribs 46 on the facing surface ofinsert 12, - around and between
cap sealing flange 40 and the roughened, cap-facing surface ofinsert groove 36, - around and between the roughened, cap-facing surface of
insert groove 38 and thecap 14; - down through the cap and
neck threads - past the cap
anti-tamper ring 56 to atmosphere; - and as shown by the arrows in FIG. 6.
- A
sealing ring 58 is located between theneck rim 42 and theinsert groove 38 to seal the insert with the container; as the insert, perforce, by-passes the cap'sintegral sealing flange 40. - This complex gas passage effectively forms a labyrinth seal on the air-side of the microporous diaphragm; thus
- the cap protects the membrane from any contamination coming from outside during storage or transport of the container;
- the same cap can be used for vented and non-vented applications, simply by insertion of a vented closure into the cap;
- the membrane is welded to the insert to ensure that it remains liquid-tight; and,
- the cap has no gas ports or perforations.
- By this means, a non-vented cap-closure can readily and simply be converted to a vented closure by either replacing or by-passing the existing sealing member within a
conventional container cap 14 withinsert 12, includingmembrane 24 andcup 26; provided that there is a sufficient gas leakage path between the cap and neck threads.
