Definitions

  • the present invention relates to a lockable closure for a container or a fluid flow outlet or inlet, in particular to a lockable closure for a container for fluids.
  • Lockable closures for fluid containers are known in which a combination lock means is actuated in order to allow a user to access the contents of the container.
  • Prior art devices are generally adapted for use with specific container types or sizes, for example to fit to a specific pattern of screw thread or shape of the container body and/or opening. Additionally prior art closures often have restricted flow pathways leading to limited flow rate and difficulty of ensuring the flow pathway does not collect residue and remains clean in use.
  • a lockable closure device that is able to fit to more than one size or shape of container, and provides an unimpeded flow path and an unobstructed free-flow aperture will have utility.
  • a set of cylinders with marked flanges are positioned through the annular shell, superimposing the sleeve member, restricting its upward movement.
  • the release position of the sleeve member can only be facilitated by rotating the flanges to a predetermined alignment.
  • This device fixes to the threads of the neck of the container and so is limited to a specific container and thread design. It is not adapted to fit to a pipe or to a tap outlet. It has a fluid pathway that has a rapid change of diameter and has a small aperture and sharp edges in the sealing region, so offering resistance to flow and being unsuitable for viscous liquids or suspensions, while further being difficult to clean.
  • the aperture restriction makes this device an inefficient pouring system.
  • United States Patent Application US-A1-2011/0079058 provides a locking apparatus for containers, vials and bottles that comprises a combination lock to be applied to a generic bottle or vial or for a custom bottle.
  • the locking apparatus comprises a locking subassembly: a housing, a collapsible portion on the housing or on a separate washer piece, at least one indicia ring, at least one tumbler key ring, and a setting plug; the locking subassembly will engage a first bracket, which can be mounted on a generic bottle or vial or to a custom bottle with a top end, which has a integrated bracket end.
  • United States Patent Application US-A1-2003/0089145 relates to a twist closure for a bottle which can be used to close plug-in openings of objects.
  • the invention proposes a pull member which can be displaced axially by virtue of a rotary handgrip being rotated and is intended for actuating a retaining element.
  • This device comprises a locking cap and either a second component - the first bracket - which must be passed over the outside of a generic vial to lock to the cap, or the locking cap must be used with a specifically adapted vial. Therefore this device does not provide a simple, single component lockable closure. Further it has no provision for a flow path for liquids.
  • the present invention provides a lockable closure that in preferred embodiments may be used with generic, non-modified containers, and that may comprise a fluid flow pathway that is lockable and that may be used with fluid containers, and other fluid inlets or outlets such as pipes or taps, is self-contained and does not require ancillary components.
  • fluid outlet a fluid pathway such as a neck of a container, a nozzle, a spout, tube or other conduit through which a fluid may flow, and both directions of flow, either first through the conduit and then through the closure, or first through the closure and then through the conduit, and encompassed within the description and claims.
  • a lockable closure for an container comprising:
  • the closure comprises a fluid pathway through the closure that in the first position of the cap housing is open and in the second position is closed.
  • the container retention means comprises an opening extending within it
  • the actuation means comprises a further opening extending within it
  • the cap housing comprises yet a further opening extending within it and being defined in part by an internal surface of the cap housing, the fluid pathway extending through the said openings.
  • the outlet is the outlet of a container for fluid such as a bottle and the closure is adapted to seal mechanically to the interior surface of the container.
  • the outlet may comprise a pipe or tap and the closure is adapted to seal to the interior surface of the pipe or tap.
  • the lock means is located concentrically with the cap housing. In this way the cap housing and lock means can be concentric to the outlet.
  • the operating means are usable to control the engagement of the retention means with the interior surface of the container.
  • the operating means is adapted to engage the actuation means so as to cause movement of the actuation means in response to movement of the operating means.
  • the closure further comprises a cap armature having an open pathway extending within it.
  • the retention means, the actuation means, the operating means and the cap housing may be mounted on the armature and being moveable relative to it.
  • the fluid pathway extends through the open pathway within the armature and is closed in the second position of the cap housing by engagement of a perimeter region of the internal surface of the cap housing with a perimeter region of the armature forming a fluid tight seal.
  • the fluid pathway comprises a 'free-flow' pourer, adapted to provide a high fluid flow rate.
  • the pourer opening of the fluid pathway comprises two or more manifolds arranged around a central axis.
  • the closure further contains a cap ring mounted on the closure that engages with the outer surface of the container.
  • the cap ring is adapted to engage with the outer edge or lip of the container neck.
  • the cap ring is adapted to seal to the outer edge of the container neck.
  • the retention means comprises a flexible member that engages mechanically with an internal perimeter region of the container so as to form a fluid tight seal to the interior of the container. In this way the retention means seals against leaks from the container to the exterior, while leaving open the fluid pathway through the interior of the cap components as described above.
  • the flexible member may engage the outer edge of the container opening in order to provide a fluid-tight seal.
  • the flexible member has a distal end attached to the actuation means and a proximal end held in a constant axial position by a portion of the armature, such that when the actuator moves axially with respect to the armature the flexible member is caused to contract or expand axially, so being caused to flex outwards adjacent to its distal end.
  • the locking means comprises a combination lock means that when unlocked allows movement of the cap housing between the first and second positions.
  • the cap housing when in the second position the cap housing prevents access by a user to the operating ring, and in a particularly preferred embodiment the cap housing substantially or completely covers the operating ring so preventing access.
  • the closure comprises an interlock means that in the second position prevents movement of the operating ring or the retention means actuator.
  • the interlock means comprises a member that in the second position of the cap housing engages with a region of the operating ring or with a region of the retention means actuator so as to prevent movement of one or both, and in the first position is disengaged, so allowing movement.
  • the retention means comprises a flexible sealing surface adapted to engage with the inner surface of the container so as to form a fluid tight seal.
  • the retention means has a circular cross section and is deformable to meet and seal to the circular cross-section internal surface of the bottle.
  • the closure is adapted for use with a container having one or more container features formed on its inside surface, the container retention means having one or more retention features adapted to engage in use with the container features.
  • retention features may comprise a specific shape or orientation of one of more surfaces or edges of the retention means, for example one or more teeth, latching features, flattened or more highly curved regions of the retention means.
  • the components of the closure as described above are substantially circular in cross-section and have an axial length, being substantially cylindrical in appearance though of varying internal and external surface profiles.
  • the fluid pathway through the closure preferably comprises pathways through the components, the fluid pathway having a smooth variation in cross-sectional dimension.
  • the seal region between the cap housing and the closure armature comprises an annular region having a thickness dimension that changes continuously with distance along the fluid pathway from inside the container to the outside of the closure, so avoiding sudden changes and sharp edges that impede flow and may trap residual liquid, so facilitating higher flow rate and easy cleaning compared with devices of the prior art.
  • the degree of flexure of the retention means is controllable by the operating ring, and hence a user may control the degree of flexure and hence the sealing of the closure to the container by applying a given degree of rotation.
  • the closure may be used with a range of container sizes and shapes, in contrast to closures of prior art.
  • the closure of the invention may be used with or adapted for use with other forms of fluid outlet or inlet, such as a pipe, a nozzle, a spout, a tube or other conduit through which a fluid may flow, for example in fluid communication with tubes, tanks, taps or the like.
  • Figures 1 to 17 show a first embodiment of the closure 10, having a fluid pathway through it and adapted to control flow of liquid from a container, and adapted to fit to a substantially cylindrical bottle-shaped container. It will be appreciated that such an embodiment with minor changes may fit to different internal profiles of the container, and in some embodiments may be adapted to fit to a specific container design or to a range of containers having different shapes and dimensions, and in further embodiments may be adapted to fit to a liquid outlet such as a pipe or tap.
  • Figure 1 shows a side view and Figure 2 shows a three quarter view of an embodiment of the invention, in which a closure 10 is inserted into a container 12, the closure comprising a retention means 14, a cap armature (also referred to herein as simply an 'armature') 24 housing or retaining a cap ring 22, adapted to engage with the top of the container neck, a cap housing 18 and a locking means 20.
  • the cap housing is shown in the locked position, having a lower edge adjacent to the upper edge of the armature.
  • Figure 1a shows a detail of the embodiment in Figure 1 at E, showing a projection on the cap armature 24 engaging with a recess in the edge of the cap housing 18.
  • a projection on the cap armature 24 engaging with a recess in the edge of the cap housing 18.
  • the cap housing and the armature 24 have a stepped detail 29 to limit the amount of axial sliding between them.
  • Figure 3 shows a top view of the embodiment in situ on a container 12.
  • Figure 4 shows a cross section of the embodiment in Figure 3 at A-A and
  • Figure 5 shows a cross section of the embodiment in Figure 3 at B-B. Details of the internal structure of the closure are shown.
  • the closure 10 is shown in a second position as referred to above, that is, locked in place in the container 12 and with the fluidic pathway 30 closed.
  • the retention means 14 comprises a flexible cylindrical member 32 that in the closed position is flexed outwards so as to engage with the internal surface of the container, and comprises a sealing surface 34 that forms a liquid-tight seal against the inner surface of the container.
  • the retention means is actuated by a retention means actuator 16, here a rigid cylindrical member located inwards of the flexible member 32 and concentric with it, and attached to the flexible member 32 at its distal end 35.
  • the flexible member 32 is mounted against or attached to the cap ring 22 at its proximal end 36. It will be seen from Figures 4 and 5 that axial movement of the actuator 16 relative to the cap ring 22, as held in position by the armature 24, will cause axial compression of the flexible member 32, so causing the flexible member 32 to bulge outwards and to engage the inner surface of the container.
  • the bulge of the flexible member completes a triangular shape as shown in Figures 4 , 5 , 15 , and 17 .
  • FIG. 11 and 13 shows the flexible member 32 in an unbulged and uncompressed condition.
  • Operating ring 26 comprises features, for example a screw thread or flexure or spring, that engages and operates with retention means actuator 16 so as to cause such axial movement of the actuator when the operating ring 26 is rotated or pushed. Hence rotation, pushing or indentation of the operating ring 26 causes the retention means to bulge radially outwards and to grip the container.
  • the components of the closure are mounted on and are located concentrically external to a cap armature 24.
  • the cap housing 18 is movable axially relative to the cap armature 24, movement being controlled by the lock means 20, here shown as a combination lock having three locking rings located axially adjacent one to another.
  • the fluid pathway 30 through the closure passes through pathways through the interior of the components, and is closed in the second, locked position of the closure shown in Figures 1 to 5 by the engagement of the armature 24 with a region of the internal surface of the cap housing in the upper region of the fluid pathway as shown at region 28.
  • Figure 6 shows an exploded view of the embodiment in Figures 1 to 5 with parts numbered similarly.
  • O rings 38 and 39 seal the fluidic pathway from the operating components of the closure.
  • the actuator 16 comprises one or more rails 54 allowing actuation along an axial direction, preventing rotation, the rails being shown in cross section in Figure 8 .
  • the lock means 20 comprises three locking rings 40, 42 and 44, each having a series of numerals, for example 0 to 9, on its external edge, a flexure detent 50 and an unlocking groove 48, the rings being mounted in a housing body 52.
  • the armature 24 has an inner barrel having three locking teeth 52, each corresponding to an unlocking groove 48 in a locking ring. While this embodiment is shown as having three locking rings, it will be apparent that two, or four or more may be provided along with corresponding features forming part of other components of the closure.
  • the flexible member 32 of the retention means 14 is in some embodiments moulded into a pre-formed shape, which in some embodiments may be suitable for it to be retained within a container 12 or outlet such as a pipe (not shown), and the movement of the actuator 16 may then stretch the flexible member into a flatter, more axially uniform or even substantially cylindrical shape so that it may be inserted into a container, as shown in Figures 11 and 13 .
  • the flexible member may be moulded so as to be more axially uniform, or substantially cylindrical when relaxed, compression resulting from movement of actuator 16 then causing the flexible member to bulge.
  • the flexible member 32 is shown in the relaxed case in Figures 11 and 13 and in the compressed case in Figure 4 , 5 , 15 , and 17 .
  • movement of the operating ring 26 preferably adjusts the degree of axial compression of the flexible member, so adjusting the degree of radial bulge and hence the sealing properties to the container inner wall.
  • the tightness of seal may be adjusted by the user to achieve adequate liquid sealing.
  • the operating ring may be provided with a click-stop mechanism to indicate a preferred sealing position suitable for use with a given container type. This feature allows the closure to be used with a variety of sizes and shapes of containers or with other liquid outlets, according to the embodiment.
  • Retention means 14 is formed from a thin elastomeric membrane.
  • the retention means 14 is preferably formed from a compliant material such as a thermoplastic elastomer or a rubber.
  • the retention means 14 has two forms. In one form the retention means is adapted to engage against an internal surface of an outlet such as a pipe or the container. In the other form the retention means is adapted to be inserted into and to be removed from the outlet or container.
  • the retention means 14 has a hollow tube shape when in the form adapted to put into and taken out of the outlet or container. In this form the retention is means is unloaded.
  • the form of the retention means 14 adapted to engage against the internal surface of an outlet or container 12 has different shapes at either end. One end is fixed to the cap ring 22. This end is the hollow tube shape that is unaltered by changing the form from disengagement to engagement.
  • the other end of the retention means 14 is the end that is inserted first into the pipe opening or bottle neck opening is attached to the retention means actuator 16.
  • This end has the shape of a hollow tube.
  • the form of the retention means 14 adapted to engage against the internal surface of a pipe or bottle neck 22 has a different shape at the end that is inserted first into the pipe opening or bottle neck opening. This end is attached to the retention means actuator 16. In this form the retention means actuator 16 has moved this end toward the other end of the retention means.
  • the two hollow tube ends are closer together in this form.
  • the hollow tube is made from flexible elastomeric material and the portion of the hollow tube between the ends gets squeezed as they are drawn together. The portion of the hollow tube between the ends has to expand outwards. The expanded tube seals against the internal surface of the pipe or bottle neck 22.
  • the retention means comprises a washer shaped flap that acts a diaphragm.
  • the inner perimeter of the flap is integral with the outer surface of the retention means tube.
  • a washer flap is made from a soft smooth flexible material and so the washer surface 34 is compressed against the inner surface of the pipe.
  • the engage the retention means 14 against the pipe inner surface the operating ring 26 is turned.
  • the operating ring 26 is screwed on the retention means actuator 16.
  • Turning the operating ring 26 forces the retention means actuator 16 to move linearly along them mutual axis of the ring 26 and actuator 16.
  • One end of the tubular retention means 14 is attached to the retention means actuator.
  • Turning the operating ring 26 one way moves the two ends of the retention means apart to contract the diameter of the tubular retention means and disengage it from the pipe inner surface.
  • Turning the operating ring 26 the other way moves the two ends of the tubular retention means together. This expands the diameter of the tubular retention means to engage the inner surface of a pipe or bottle neck.
  • the retention means 14, which is a hollow flexible tube, and the cap ring 22, which is a hollow ring to which one end of the hollow tube is fixed, may be supplied together for use with a standard cap housing 18 for use as a pipe or bottle closure.
  • a use-able pipe closure that engages and seals to the pipe and prevents and allow flow through the pipe may be made by assembling the hollow tube retentions means 14, cap ring 22, and standard cap housing.
  • One end of the hollow tube retaining means 14 is connected to the cap ring 22 as shown in Figure 4 .
  • the cap housing is connected to the other end of the hollow tube retaining means 14.
  • the cap ring 22 is slide-ably connected to the cap housing 18 permitting axial linear motion of the cap housing 18 relative to the cap ring 22. Sliding the cap housing 18 one way moves the ends of the hollow tube 14 closer together causing the portion of the tube between the ends to bulge outwards to a larger diameter so as to engage the inner wall of a pipe or bottle neck and to open the flow passageway. Sliding the cap housing the other way causes the tube diameter to contract and release the diameter of the tube 14 to contract and release from the inner surface of the pipe or bottle neck.
  • Cap ring 22 holds operating ring 26 in place within the armature 24.
  • cap ring 22 has press fit teeth on its external flange 56 which permanently lock into place within armature 24, for example within features 58, when fitted into it.
  • corresponding threads 60 and 62 are provided on the actuator 16 and the operating ring 26, so that by turning operating ring 26 the actuator 16 is moved along an axial direction guided by rails 54.
  • the locking means is unlocked when for each of the locking rings 40, 42 and 44 the unlocking groove 48 is aligned with the corresponding locking tooth 52.
  • Flexure detents 50 are integral to the locking rings 40 to 44, to provide a positive location for each rotational increment 0 to 9.
  • the detents 50 also provide added security to the prevention of combination lock tampering as every increment turn will have a pre-loaded feel to the user, so disguising the change in resistance when the locking ring is rotated to its unlocked state during tampering.

  • Figure 8 shows a cross section of the embodiment in Figure 7 at C-C, showing the rails 54.
  • the cap armature 24 comprises a bullet-shaped profile 70 within the diffuser region of the armature, providing low flow resistance for exiting liquids, hence promoting the 'free-flow' characteristic of the closure.
  • Liquids exit through manifold regions 72, shown in Figure 9 as being in four regions disposed around the bullet shaped centre 70. Sealing of the fluid pathway occurs at the outer edge region 28 of the cap housing inner surface 74 and the armature region 70.
