The present invention relates to a device which attaches to a container for flowable material, such as a fluid or a solid of such consistency as to be capable of behaving fluidly, e.g. powder, grain etc, and to a kit of parts for the same. The device attaches to a container such as a bottle, carton or pouch, and improves or facilitates the delivery of material from the container. The present invention particularly relates to a portable liquid delivery device which is suitable for attaching to an array of different liquid containers. A particular application of the invention relates to drinking containers.
Liquids are often purchased in a sealed container, e.g. a bottle, carton or pouch, which requires opening before the contents are delivered directly from the container or indirectly via suitable means, such as a straw or spout. Delivery of the liquid from the container may include dispensing, e.g. pouring, of the liquid into a secondary container or consumption, e.g. drinking, from the container by a person.
Bottles generally comprise a screw cap which requires removing before the liquid therein can be delivered therefrom. Cartons and pouches generally comprise a flap which is folded and adhered to an upper, outer part of the carton or pouch. The integrity of the adhesion is typically compromised by unfolding the flap which is then torn to access the liquid in the carton or pouch. The unfolded flap may define a spout to facilitate pouring the liquid from the carton or pouch. Cartons and pouches often comprise a frangible portion, e.g. foil, the integrity of which is compromised by puncturing, for example, to allow the liquid to be delivered from the carton or pouch. Where the liquid is consumed from the carton or pouch, the frangible portion can be punctured by a straw and the straw used to consume the liquid from the carton or pouch.
A disadvantage of containers, such as a bottle, carton or pouch, relates to the delivery of fluid from the container. In particular, liquid is often difficult to pour from such containers especially where a degree of accuracy is required. This may be particularly inconvenient where liquid is being dispensed from a primary container into a secondary container, especially when an access opening of the secondary container is small. Also, liquid often drips from the primary container after dispensing which is also inconvenient particularly where mess or staining by the liquid is undesired.
An example of a dispensed liquid is engine oil which is purchased in a container having a neck or collar defining an aperture which is sealed by a screw cap fitting over the neck or collar. To avoid spillage, the oil is typically poured from the can into the engine via suitable means, such as a funnel. Where a funnel is unavailable, oil spillage is a common problem and particularly undesirable. Another example may be where the liquid is wine which is purchased in a glass bottle having a neck defining an aperture which is sealed by a cork fitting within the neck or a screw cap fitting over the neck. The neck of the bottle is generally inadequate to prevent dripping when pouring or decanting the wine, which is particularly inconvenient due to staining. A further example may be where the liquid is milk suitable for baby consumption which is purchased in a carton. The milk generally requires transferring from the carton to a suitable bottle generally including a teat for the baby to drink from. Carrying a separate carton around may be inconvenient for a parent or carer, especially when away from home or in a public place having limited facilities. Where the carton comprises a foil portion which is punctured to open the carton, transferring the milk from the carton to the baby bottle may be particularly difficult and inconvenient.
Consuming liquid directly from drinking containers can also be particularly difficult or impossible for some people. Such people include those who are unable to drink independently, e.g. babies or people with special needs including the elderly, and those who have a particular medical condition which hinders their ability to drink directly from such containers. These people often require additional means, e.g. a teat or mouthpiece, to allow them to drink from the container, either independently or dependently.
Gaining access to the liquid in liquid containers can also be a problem for some people, particularly where a degree of accuracy is required such as piercing a small area of foil in a carton or pouch with a straw. People with medical conditions including arthritis or Parkinson's disease, for example, may find the conditions hinder their ability to open such containers prior to consumption or dispensation of the liquid therein.
A first aspect of the present invention provides a delivery device for flowable material comprising:
Preferably, the device comprises at least one further attachment part which is selectively engageable with the first delivery part. The further attachment part is differently conformed to the first attachment part to allow the first delivery part to be attached to a differently structured and/or sized container and/or to be attached in an alternative manner. The difference in structure may range from a bottle having a neck or collar defining an outlet aperture to a carton having a frangible portion, the integrity of which requires compromising to form an outlet aperture in the carton for the delivery part to attach to.
Preferably, the first or further attachment part connects the delivery inlet with the container outlet aperture. Suitably, the delivery inlet may connect directly to the outlet aperture. Alternatively, the attachment part may define an attachment conduit having an attachment inlet and attachment outlet wherein the attachment part is engageable with the delivery part in such a manner that when so engaged the delivery conduit and the attachment conduit define a fluidly continuous channel through the device from the attachment inlet to the delivery outlet.
The interchangeability of the attachment part advantageously enables the device to be attached to a range of containers of varying structures having different means of opening an outlet aperture thereof, such as a screw cap, cork, ring pull, unfoldable flaps and/or frangible portions or other means. The device is advantageously a universal material delivery device which may be attached in sealing engagement to more than one type of container.
Preferably, the device alternatively or also comprises at least one further delivery part which is selectively engageable with the first or further attachment part. The further delivery part is differently conformed to the first delivery part. The first or further delivery part may be selectively engaged with one of the first or further attachment parts depending on the desired functionality of the delivery part. This may be particularly convenient for providing a different means of delivering the material from the container. For example, the first delivery part may be a form of spout for pouring material from the container, whereas at least one further delivery part may be a form of mouthpiece suitable for consuming material, e.g. liquid, directly from the container. Advantageously, the device may also provide multiple functionality to a user to allow flowable material to be delivered from the container.
One embodiment of the attachment part comprises an enclosure formation adapted to engage over and around an aperture of a container externally thereto. For example, the enclosure formation is a cap having a circular cover and wall portion peripherally extending perpendicularly from said cover to surroundingly engage around an outlet aperture defined by a narrowing in the container, such as a neck or collar of a bottle, for example. Preferably, the cover comprises an aperture complementarily shaped with the delivery part to allow the cap to attach the delivery part to the container in such a manner as to define when so connected a fluidly continuous channel from the container to the delivery outlet of the delivery conduit. Suitably, the cap may be a screw cap having a radial wall comprising a screw thread to allow the screw cap to engage with a corresponding screw thread on the neck of the container and attach the delivery part thereto. Preferably, the screw cap is sufficiently rigid to withstand forces when screwing the screw cap to a neck or collar of a container, for example. Alternatively, the cap may be a deformable cap having a peripheral wall portion which is elastically deformable allowing it to stretch over the neck or collar of a container and attach the delivery part thereto. Preferably, the deformable cap is sufficiently elastic to stretch over the neck or collar of a container whilst remaining attached to the neck or collar once stretched thereover.
An alternative embodiment of the attachment part may be adapted to insert within the outlet aperture of a container. The attachment part comprises an insert formation enabled to be inserted within a container through an aperture therein in use. The insert formation preferably defines an attachment conduit comprising the attachment inlet and attachment outlet. Preferably, the insert formation has a wide end comprising the attachment outlet and a narrow end comprising the attachment inlet.
Suitably, the insert formation may slidably insert in sealing engagement into an outlet aperture, for example defined by the neck or collar of the container, to retain the attachment part therein. Suitably, the insert formation may be a resilient material, e.g. rubber, to ensure a secure fit and sealing engagement with the neck or collar of the container is achieved. Preferably, the attachment outlet of the insert formation connects with the delivery inlet to define a fluidly continuous channel through the device from the attachment inlet to the delivery outlet. Preferably, the insert is a material providing sufficient resilience to allow the insert to be slidably inserted into the neck or collar of a container whilst providing sealing engagement when inserted therein. Sealing means may suitably be provided to securely seal the insert formation in the outlet aperture of a container. The sealing means may comprise means to increase the width of the insert formation in the outlet aperture thereby to provide an effective seal. The sealing means may comprise an elongate member extending through the insert formation, the elongate member having a first end adapted to engage with the narrow end of the insert formation and second end extending from the wide end. A shoulder may be provided at the first end to engage with the narrow end of the insert formation. A lever may suitably be coupled to the second end and adapted to move the first end upwardly relative to the container thereby to apply a force on the narrow end of the insert formation. The force applied thereto causes the resilient insert formation to bulge outwardly and seal against the outlet aperture of the container. The lever may suitably comprise a cam arrangement to provide the desired movement of the elongate movement. Suitably locking means may be provided to lock the lever in a sealed position. The locking means may comprise a locking member which may be provided over the lever when in the sealed position. Alternatively, the lever may be adapted to self-lock when in the sealed position.
Conveniently, an insertable attachment part may be adapted to penetrate a portion of a container. Suitably, the attachment part may comprise a penetrating part adapted to compromise the integrity of a container wall or a frangible portion of a container, e.g. a foil portion. Preferably, the penetrating part is substantially elongate and is rotationally symmetrical about its longitudinal axis. Preferably, the penetrating part is substantially tapered from a wide end to a narrow end or point. For example, the penetrating part may be substantially ogival. Suitably, the penetrating part may be narrow and spike-like to puncture the wall of a container or a frangible portion thereof, e.g. a foil portion, thereby to provide the outlet aperture in the container.
Preferably, the penetrating part defines the attachment conduit and comprises the attachment inlet and attachment outlet. Preferably, the wide end comprises the attachment outlet. Suitably, the attachment inlet may be disposed at the narrow end or point of the penetrating part. Alternatively, the attachment inlet may be disposed around a surface of the elongate penetrating part to define one or more attachment inlets on the side of the penetrating part. Preferably, the delivery part connects with the penetrating part. Preferably, the attachment outlet of the penetrating part connects with the delivery inlet to define the fluidly continuous channel through the device from the attachment inlet to the delivery outlet.
The penetrating part suitably creates the outlet aperture in the container and attaches the delivery part to the container whilst connecting the delivery inlet of the delivery part to the container to allow flowable material to be delivered therefrom. Preferably, the penetrating part is adequately rigid to penetrate the wall of a container or a frangible portion thereof to provide the outlet aperture therein.
An insertable attachment part may include a penetrating part and an insert formation as above described which may be provided discretely or by a single common structure.
An insertable attachment part may comprise suitable sealing means to provide an effective seal between the penetrating part and the outlet aperture in the container wall. Such sealing means may be similar to the sealing means of the insert formation as described above. The sealing means may further comprise a sealing plate having an upper face and a lower face. The sealing means may comprise a washer which engages with the lower face of the sealing plate. The washer may seal the outlet aperture of the container and may engage with an inner or outer surface of the container. Suitably the lever may engage with and/or lock against the upper face of the sealing plate. Suitably one of the insert formation or penetrating part may comprise the sealing plate. Suitably the sealing plate may made of a resilient material.
Suitably, the penetrating part may comprise securing means to ensure the penetrating part is securely attached within a container and, for example, in or on an outlet aperture. Suitably, the securing means may comprise a plurality of annular protrusions disposed around the penetrating part. The securing means may comprise a screw thread. Alternatively, the securing means may comprise one or more barb-like protrusions extending from the penetrating part to prevent the penetrating part detaching from the outlet aperture of the container. Conveniently, the securing means may comprise the sealing means. For example, the annular protrusions may securely attach the insertable attachment part to the outlet aperture and also prevent material, e.g. liquid, leaking past an attachment part/outlet aperture interface to provide effective sealing means.
In one convenient embodiment, the delivery part is elongate and defines a delivery conduit disposed along its length connecting a delivery inlet generally at a first end and a delivery outlet generally at a second end. Preferably, the delivery part comprises a cylindrical body portion. Preferably, the body portion comprises a delivery shoulder, having a first face and second face, which annularly extends from the body proximal to the first end.
Optionally, in combination therewith, the attachment part, in the form of an enclosure formation as above described, selectively engages with and attaches the delivery part to the outlet aperture of the container by engaging with the shoulder to retain the delivery part thereon.
Preferably, the enclosure formation comprises an aperture to allow the enclosure formation to mount over the delivery part and interface with the first face of the delivery shoulder. Where a screw cap is screwed or a deformable cap is stretched over the neck or collar of a container, the second face of the delivery shoulder may interface with a corresponding face of the container in the vicinity of the neck or collar to allow the cap to clamp the delivery part to the container. Preferably, the delivery part is clamped in sealing engagement to the container.
In another convenient embodiment, a screw threaded attachment part is provided together with an insertable delivery part, an insertable formation or penetrating part of which comprises a screw thread proximal to a wide end which corresponds to the screw thread in the enclosure formation such as a screw cap. Where the penetrating part is required to open a container, e.g. a carton or pouch, or the insert is required to attach the delivery part to the neck or collar of a container, the screw cap will generally not be required to attach around the neck of a container, e.g. screw neck of a bottle. Therefore, the screw thread in the screw cap may conveniently be utilised to attach the penetrating part or insert to the delivery part. The delivery shoulder of the delivery part will be disposed between the screw cap and the wide end of the penetrating part or insert and screwing the penetrating part or insert into the screw cap will clamp the device together. Conveniently, a part of the screw thread around the wide end of the penetrating part may be used as the securing means to attach the device to the outlet aperture of the container, in a similar manner to the plurality of annular protrusions, as described above.
Suitably, as described above, the device may further comprise sealing means to seal the insert formation or penetrating part to the container. Suitably, the attachment part comprises a through conduit having an internal thread corresponding to a screw thread of the penetrating part or insert formation allowing the same to attach to the attachment part.
The sealing means may comprise actuation means to pull the attachment part down on to the container to secure and seal the device thereon. The sealing means may comprise a sealing plate which engages with the container to seal the device thereon when the attachment part is pulled thereagainst. Suitably the attachment part is slideably mounted to the sealing plate. Suitably the sealing plate comprises an aperture to allow the penetrating part or insert formation to extend through the sealing plate to attach to the attachment part. The sealing plate suitably comprises one or more upwardly extending projections complementarily shaped with one or more recesses in the attachment part.
The actuation means may be adapted to urge the penetrating part or insert formation in a direction outwardly from the container. The securing means, for example a screw thread, provided on the penetrating part will secure the penetrating part to the container whilst the actuation means will pull the sealing plate downwardly against the container. The container is suitably squeezed between the sealing plate and penetrating part thereby to securely clamp and seal the device to the container.
The actuation means may comprise one or more levers to actuate the sealing means. The levers are suitably adapted to engage with the sealing plate and move the sealing plate away from the attachment part and relative to the penetrating part or insert formation. As described above, the levers may self-lock in a sealed position or a locking member may be provided on the device which is adapted to lock the levers in the sealed position. Suitably the locking member may be rotatable on the device and may be rotated over the levers thereby to lock them in the sealed position. Alternatively, the locking member may be fixed and the levers may be rotatable thereby to be rotated under the locking member when in the sealed position. Suitably, the levers are hingedly attached to the attachment part. Suitably providing the levers with an eccentric or offset hinge axis will provide a camming arrangement to engage the levers with the sealing plate and provide a self-lock mechanism when in the sealed position. Suitably two levers are provided and preferably at 180 degrees relative to each other on the attachment part.
In a further alternative embodiment, where the cap is required to attach to a neck or collar of a container, the wide end of the penetrating part or insert may comprise a screw thread which corresponds to a screw thread of the delivery part allowing the penetrating part or insert and delivery part to be screwed together. The screw thread may project perpendicularly from the wide end of the penetrating part or insert and correspond to a threaded bore in the first end of the delivery part, or vice versa. When screwed together, the cap may suitably be clamped between the penetrating part or insert and the delivery part. Alternatively, the cap aperture may allow the cap to be placed over the delivery part and interface with the first face of the delivery shoulder thereby to clamp the device to the container when screwed to the neck or collar thereof, for example.
Preferably, the delivery part comprises a projecting portion terminating in the delivery outlet to define a desired flow direction. Suitably, the projecting portion may take many forms depending on its desired functionality. For example, the projecting portion may comprise a mouthpiece. The mouthpiece, which terminates at the delivery outlet, may be offset to the longitudinal axis of the delivery part. Such a mouthpiece may be shaped in a similar manner to a mouthpiece commonly used on a drinking bottle for training babies or toddlers, often known as a trainer cup, for example. Alternatively, the projecting portion may be adapted to provide a non-drip spout which may be particularly important where staining from spilled liquid after dispensing is extremely undesirable, such as when serving red wine in fine restaurants having white tablecloths. Alternatively, the projecting portion may comprise a teat suitable for feeding babies who are still at breast feeding age. Suitably, the teat may be anti-colic or may be adapted to provide a desired flow rate. The teat may be suitable for users with special needs, e.g. a cleft pallet, where the user is unable to suck on a conventional teat and requires the teat to be pressed to encourage a liquid, for example, to flow from the container into the mouth of the user. Further alternatively, the projecting portion may comprise an elongate straw-like projecting portion. Such a straw-like projecting portion may be suitable for people who are unable to drink independently. In a further embodiment, the delivery part may comprise a ‘push-pull’ valve which closes and seals the container when in the ‘push’ position and allows liquid to be delivered from the container when in the ‘pull’ position. Such a delivery part may be particularly suitable for participants of outdoor pursuits, e.g. cyclists or walkers. Alternatively, the projecting portion may comprise a shaker-type outlet which may be suitable for sprinkling powder or granular material in a cooking application, for example. Further alternatively, the projecting portion may serve as a delivery means in like manner to a funnel for delivering material to another container.
The delivery part may suitably be adapted to receive a closure to seal the delivery outlet when not in use. The closure may screw over the delivery outlet or may be a bung-like member which screws or pushes into the delivery outlet to close and seal it. The closure may be connected to the delivery part by a flexible arm which allows the closure to be arranged in sealing engagement with the delivery outlet or be removed therefrom to open the delivery outlet, whilst conveniently being connected to the delivery part at all times. Advantageously, the closure is thereby prevented from becoming detached from the delivery part which could inconveniently result in misplacement. Suitably, the closure may comprise locking means to prevent the delivery outlet being opened when undesired or to provide a degree of security to prevent unwanted access to the material within the container. A lockable and secure closure may be particularly desirable where the material is potentially harmful, e.g. a toxic chemical or medicine, and access thereto by certain people is often undesirable, such as children. Alternatively, the closure may seal the delivery outlet before the delivery part is attached to a container and only removed when delivery of material from the container is required. This advantageously provides a sealed container including the device which is resistant to contamination of the material therein prior to use, which may be particularly desirable in a medical environment, for example.
Suitably, the delivery part may comprise a valve which prevents material leaving the delivery outlet when not required. A suitable valve may comprise a one-way valve, e.g. a ball valve. Such a delivery part may be particularly suitable to prevent material leaking from the delivery outlet when the container falls over or is accidentally dropped.
Suitably, the delivery part may comprise pressure equalisation means to allow air into the container to replace the material leaving the container when being delivered therefrom. Pressure equalisation means conveniently tends to equalise air pressure within and outside the container during delivery of the material therefrom. This is particularly useful where the delivery part comprises a mouthpiece or straw and material is being sucked from the container. A reduced pressure in the container may cause the container wall to collapse and eventually delivery of the material may inconveniently cease. Suitably, the aeration means may comprise an air passageway disposed in the delivery part suitably adapted to fluidly connect the interior of the container with the atmosphere to prevent a substantial change occurring between atmospheric pressure and container pressure. Preferably, the air passageway is separate from the fluidly continuous conduit through the device.
Preferably, the delivery part is a similar material to the attachment part. A portion of the delivery part may be substantially flexible and a portion may be substantially rigid. For example, where the delivery part comprises a teat, the teat must be substantially flexible, as will be understood by a skilled person in the art, whereas a mouthpiece, similar to that found on a training cup for babies, must be substantially rigid. Preferably, the portion of the delivery part comprising the delivery shoulder is substantially rigid to adequately engage with the attachment part, as described above.
Suitably, the device may comprise a handle to facilitate handling the container when the device is attached thereto. Suitably, the handle may attach to a delivery part or attachment part. Suitably, the handle may comprise first and second arms being joined together at one end. Preferably, the arms are angled relative to each other. Preferably, a free end of the handle attaches to the delivery part or attachment part. Preferably, the first arm extends outwardly and substantially perpendicularly from the delivery part or attachment part and the second arm is orientated substantially perpendicularly relative to the first arm to define a handle having a right-angled profile.
Alternatively, the one or more levers of the sealing means, as described above, may provide a handle.
Preferably, the interchangeable delivery parts and attachment parts of the device are formed of the same material. Preferably, the device is a material of food-grade quality being suitable for sterilisation using known techniques. The parts may be supplied pre-sterilised. This is of particular importance where the device is used in a medical environment or by people who are easily susceptible to illness, e.g. babies. Suitable materials for the device may include rubber or plastic.
Preferably, the device is re-usable. However, the device may be disposable and/or recyclable.
Preferably, the device is substantially compact and portable which is particularly convenient for carrying on one's person, for example.
A kit of parts is also provided comprising the device and suitable packaging for the device to be contained or stored in when not in use. Suitably, one or more devices in accordance with the present invention may be contained in an assembled or disassembled state within the packaging. Preferably, the packaging is complimentarily shaped with the device to provide compact packaging enveloping the device. Suitably, the packaging may be adapted to prevent the device moving around within the packaging. For example, the packaging may comprise one or more ribs extending inwardly from a packaging wall which are complimentarily shaped with the device to ensure the device is securely contained therein. Preferably, the packaging comprises two parts which engage together to collectively envelope the device. The two parts of the packaging may engage and lock together at corresponding ends. Alternatively, the packaging may comprise a hinge and the two parts may engage and lock at corresponding edges. Preferably the packaging is an aesthetic design, having smooth contours, like an egg, for example.
