Definitions

  • the present invention relates to improvements in or relating to holders for containers and to containers embodying the holders.
  • holders that provide attachment, handling and delivery mechanism for containers such as pouches or sachets by attachment thereto and to the containers derived thereby.
  • the invention is particularly useful with containers containing ingredients for foods and beverages including liquid foods such as infant foods particularly milk.
  • the foods and beverages can be supplied in hermetically sealed pouches or sachets perhaps as a powder and which can be opened and attached to the holder to produce the container for handling during the provision of water to make up the food or beverage and optionally to provide delivery means and enable handling of the container for delivery of the contents to the consumer.
  • Baby bottle systems comprising a hermetically sealed pouch for infant food sealed to a holder which can provide a hermetic seal, and a cap which can contain a collapsed teat which can be released to provide the delivery mechanism for the infant food are known.
  • the invention therefore provides a holder system for a sachet or pouch comprising a holder comprising a ring providing an opening, an external circumferential band provided towards the upper end of the exterior of the holder, and a slip ring designed to fit around the exterior of the ring of the holder to hold the open mouth of the sachet or pouch between the ring of the holder and the slip ring.
  • the shape of the holder and slip ring may be chosen according to the shape of the pouch or sachet with which they are to be used. Cylindrical is a preferred shape although rectangular or square systems may be used. A cap may be provided to cover the opening in the holder for cleanliness and sealing purposes.
  • the external circumferential band of the holder is preferably located at the top of the holder and provides a stop to prevent the slip ring passing beyond the top of the holder when it is applied as a snap fit around the open mouth of the sachet located around the ring of the holder to hold it against the exterior of the ring of the holder.
  • the holder and the slip ring are shaped so that when the slip ring is snapped in place around the holder a small gap is provided under the circumferential band between the holder and the slip ring to accommodate a small amount of the pouch or sachet to ensure it is properly fitted around the holder.
  • the slip ring may be placed around a pouch or sachet that is to be attached to the holder, the holder may then be placed in the open end of the pouch or sachet so that the top of the open mouth of the pouch or sachet lies against the external wall of the ring of the holder and the upper rim of the open mouth of the pouch or sachet is against the bottom of the circumferential band of the holder perhaps condensed into the gap between the holder and the slip ring.
  • the slip ring may then be engaged with the holder by means of the snap fit in order to secure the pouch between the exterior surface of the holder and the slip ring to form the container.
  • the container comprising the pouch attached to the holder system is then ready for use such as the delivery of its content or for filling.
  • the pouch and the holder system can be separated simply by disengaging the slip ring from the holder.
  • the holder system of the holder and slip ring could be reused while the pouch could be recycled.
  • the slip ring can be made from a silicon rubber or a thermoplastic elastomer to create a tighter seal which is particularly useful if the holder and slip ring are to be reused. Alternatively both components could be recycled perhaps separately.
  • the holder system also contains a delivery system for the contents of the pouch or sachet, for example if the container comprising the holder system and the pouch or sachet is a baby bottle, the holder may contain a collapsed teat held within the internal space of a collar that is attachable to the holder by means of a manually placeable and removable cap.
  • the holder carries an external circumferential band at the position on the holder where the top of the open mouth of the pouch or sachet should reside so that when applying the pouch or sachet around the holder it abuts the base of the circumferential band and the user knows that it is properly located on the holder and furthermore the band prevents the holder falling into the pouch.
  • the band provides a stop for the fit of the slip ring around the holder to hold the open mouth of the pouch or sachet in position between the holder and the slip ring.
  • the fit may be a push fit, a friction fit, a press fit and/or a snap fit, a snap fit is preferred.
  • Projections such as circular beads may be provided on the outer surface of the ring of the holder and/or the inner surface of the slip ring to enable their attachment to each other.
  • a seal or gasket may be provided around the base of the exterior of the holder so that when the slip ring is engaged with the holder the seal ensures a hermetic connection between the holder and the slip ring.
  • This combined with a cap which may be provided on the opening provided at the top of the holder can provide a hermetic seal for the contents of the pouch once attached to the holder allowing hygienic storage and enabling one container filling to be used for more than one food or beverage.
  • the ring of the holder is preferably tapered narrowing in a direction away from the circumferential band so that it progressively engages with the open end of the pouch or sachet.
  • the slip ring is formed with a corresponding taper to ensure a close fit with the outside of the holder when it is engaged with the holder.
  • the holder system of this invention holds the sachet or pouch and can provide the means for the introduction of material into the pouch.
  • a delivery system for the contents of the pouch.
  • the container is a baby bottle
  • the holder may be designed to releasably engage with a delivery system comprising a collar containing a teat; the collar maybe a flat disc that snap fits into beads formed on the inner surface of the ring of the holder.
  • the collar of the delivery system is provided with means for attachment to the holder such as an internal thread which can engage with a thread at the upper end of the holder.
  • the collar may be a snap fit onto the holder.
  • the holder system includes the delivery teat system which may be in place attached to the holder. The teat system may be removed to allow material such as water to be introduced into the pouch, and may then be replaced so that the filled container is then ready for use.
  • the teat delivery system preferably comprises the teat and a collar adapted to allow the teat system to be releasably attached to the holder.
  • the teat and the collar may be integrally moulded and where they are of different materials they may be overmoulded. Generally however they are separate enabling the teat to be replaced while retaining the collar.
  • the collar preferably is injection moulded from food or medical grade material such as food or medical grade polypropylene and the teat being flexible is preferably made from medically acceptable elastomeric material such as Kraton rubber or a thermoplastic elastomer, an ethylene/propylene copolymer particularly a random copolymer or a silicon based rubber material.
  • a liquid tight seal should be formed between the collar and the teat and accordingly where they are separate components it is preferred that the collar be provided with a skirt providing an internal circular rib and the base of the teat is provided with a channel that will engage with the circular rib when the teat is passed through the central orifice of the collar.
  • the top of the holder is threaded and the teat is provided attached to a threaded collar so that it can be attached to and removed from the holder.
  • the opening of the holder allows introduction of the fork or spoon into the contents of the pouch or sachet.
  • the pouch or sachet may be provided with a compartment in which the fork and/or spoon may be contained in a hermetically sealed manner. The compartment can be broken and the fork and/or spoon retrieved and used for consumption of the contents of the sachet or pouch.
  • the holder is provided with wings extending outwardly from a position between the neck of the holder that is attached to the mouth of the sachet or pouch and the section that is attached to the collar or teat system. These wings enable the container to be held around the neck of the holder below the wings providing protection from spillage of materials being introduced into the bottle and reducing the risk of contamination of the delivery system during use by contact with the human hand.
  • the holder and the slip ring may be of any suitable material according to the use to which the container is to be put.
  • the holder should however be sufficiently rigid to provide strength and integrity to the pouch or sachet with which the container is used when the pouch or sachet contains the particular product for which it is designed.
  • the holder and the slip ring be of a thermoplastic material and is preferably prepared by injection moulding.
  • polypropylene, ethylene/propylene copolymers preferably a random copolymer, rubbers, thermoplastics elastomers or polyamides are particularly useful materials from which the holder can be made.
  • food or medical grade such as food or medical grade polypropylene.
  • Other materials that could be use include metal, paper, cardboard and natural fully recyclable material used for packaging food such as the material available as DelipacTM.
  • the holder and the slip ring may be provided with circular matching beads and grooves in order to provide an improved seal which may provide a liquid proof seal.
  • the holder and slip ring are provided with two such matching beads and grooves.
  • the holder and slip ring should be sufficiently thick to provide thermal insulation for the consumer and/or ribs may be provided on the slip ring to act as a heat sync to dissipate heat. If the contents are to be consumed through the open top of the holder using a fork and/or a spoon the opening of the holder should be large enough to allow easy introduction of the fork or spoon and yet the circumference should be such that it can readily be held by the consumer.
  • the holder may be provided with one or more beads on the inner surface of the ring to which dispense systems or caps may be secured perhaps to form a watertight seal.
  • the holder, slip ring and pouch or sachet should be of a size that allows manual squeezing.
  • the holder has an outside diameter in the range of 50 mm to 100 mm with the upper circumferential band having a width of from 2.5 mm to 10 mm so providing an opening of diameter from about 35 mm to 90 mm preferably 40 mm to 80 mm.
  • the depth of the holder is preferably from 10 to 30 mm, preferably 18 to 22 mm so allowing it to contact from 15 to 25 mm of the pouch preferably from 18.75 to 20 mm of the pouch or sachet.
  • the slip ring preferably has a depth corresponding to the depth of the holder below its circumferential band. For applications where thermal protection is not required the depth may be shorter such as for example 8 to 10 mm for both the holder and the slip ring. Holder systems of these dimensions can be used with sachets and pouches of varying volume. To increase the volume the diameter can be increased and/or the length of the pouch or sachet can be increased which can be reversed if it is required to reduce the volume.
  • small protrusions are provided around the inner ring of the holder so that an audible click is produced as the container is assembled to indicate that the components are fully engaged.
  • the slip ring may be provided with indicators of any shape particularly arrows on its external surface showing the way up in which it should be used and the direction it should be moved to engage with the holder. The indicators can also be shaped to provide additional grip for the user.
  • the invention provides the kit of components required to assemble the holder system and the holder system comprising the assembled components. Further it provides the kit additionally containing one or more sealed pouches or sachets which can be opened and assembled to the holder system. The slip ring and the holder may be reused with a series of pouches or sachets. Additionally in a further embodiment the invention provides a container comprising a flexible pouch or sachet attached to a holder system of this invention. The pouch or sachet may be filled, empty or contain ingredients for the production of food or beverage such as by mixing with water.
  • the holder should be rigid to allow the optional use of a tamperproof clip, the rigidity allows the clip to apply pressure around the top of the receptacle when attached and it is desirable that the top does not flex under the tension created by the clip.
  • the holder should be able to be held by the human hand which helps to allow the pouch to receive the fluid and maintain a consistent volume.
  • the holders of this invention may be used with a variety of pouches and sachets such as flex can, push pop, block bottom, pillow shaped and other pouches.
  • the pouch may or may not be filled with solid material or liquid and may be closed or open ended. Doy style punches are particularly useful. If the pouch or sachet with which the holder system of the present invention is used is not already pre-filled with liquid, preparation of the food or drink can be achieved as follows. After attachment of the pouch or sachet to the holder system, a seal if present over the opening in the holder may be removed. The pouch may then be filled to the desired or pre-measured level with chosen materials usually liquid which may include other pre-mixed contents. If required a delivery system may then be attached to the holder. If the pouch is pre-filled then it will be sealed and the seal broken to allow the holder to be applied.
  • the open mouth of the pouch or sachet may be the same diameter as the external diameter of the ring of the holder or it may be a few (such as up to 5) millimetres greater than the external diameter of the ring.
  • the pouch may contain material for mixing with a liquid such as water for example to produce milk, coffee, tea, soup and other foods.
  • the pouch would have a measured amount of milk powder inside with boiled water to be added as the liquid.
  • the delivery system typically the teat system including the cap would be replaced and secured to the holder.
  • a seal will be created once the delivery system is in the correct position which can be indicated to the user by an audible click.
  • the fluid delivery tube and cap mechanism With the fluid delivery tube and cap mechanism still in the sealed position, the contents may then be shaken, stirred, mixed and/or simply left in desired conditions until consumption of contents is required.
  • the cap may be removed so that the mouthpiece resurrects itself to the shape ready for use. After use, a seal may be re-established by positioning the cap over the mouthpiece and applying downward pressure.
  • the delivery system once secured into position by attachment of the collar to the holder forms a seal which is strong enough to prevent leakage. If the contents of the container need to be warmed or cooled the shape of the holder can allow the filled pouch to be immersed in water without the water touching the delivery system or the cover again preserving the sterility of the mouthpiece and contents. If the holder has wings they can be used to hold the pouch in a bath of cooling or heating fluid. It is preferable when changing the temperature of the contents of the container to have the delivery system of the container in the sealed position with the cap in place.
  • the holder system of the present invention may be used in a variety of other uses where space saving, single use and disposability are required.
  • the system may be used together with pouches or sachets which may or may not be pre-filled to provide containers containing foods and liquids such as drinks such as sports drinks, hot chocolate, coffee, tea and dairy products such as creme fraiche where the container can be stored in a refrigerator after opening.
  • foods and liquids such as drinks such as sports drinks, hot chocolate, coffee, tea and dairy products such as creme fraiche where the container can be stored in a refrigerator after opening.
  • they may provide food and drinks in military operations, they may also be used in travel such as in space travel or aircraft, in sporting activities and recreational activities such as walking and mountaineering.
  • the circumferential band may be shaped to aid eating or drinking from the container and sharp edges on the holder or slip ring should be avoided.
  • a further example of use of the containers is for the transport, storage and consumption of medicines to be taken orally and in veterinary applications where a pre-measured amount of material may be placed in a sterilized container which may then be flat packed and easily stored and transported prior to use.
  • the holder system may also be used to produce containers for storing of oils, paints and the like.
  • a delivery mechanism such as a brush attachment or sponge may also be provided.
  • the holder system can be used in containers for the collection of samples such as urine samples for analysis or use for bedridden patients.
  • a cap can be provided to seal the container after use providing economic storage when flat combined with easy assembly for use and readily disposed of or recycled after use, in this embodiment it is preferred to use a self-standing gusseted pouch.
  • the holder system may be used in containers holding gels, powders and various dissolvable materials.
  • the pouch is preferably flat in its unopened state.
  • the pouch is preferably a flexible pouch comprising a first sealed end and a second end sealed and provided with a tear line to make the second end seal a removable seal.
  • the pouch is preferably provided with a gusset at the first sealed end whereby the second seal can be removed and the pouch opened to provide a self-standing vessel wherein the walls of the pouch are of one or more materials providing a barrier to the passage of water and air in all areas including the tear line.
  • the pouch may have side seams or may be from a single piece of material.
  • At least part of the walls of the pouch are transparent or translucent and measurement marks are provided on a transparent section of the walls of the pouch to enable sight of the volume of material within the self-standing vessel.
  • the pouch may have a single marking indicating the level at which it is full of the particular contents.
  • the pouch can be provided with compartments to store various components of the container and also other useful accessories.
  • the pouch may have a compartment that holds the holder and/or the slip ring of the holder system of the invention.
  • the pouch may have a compartment that holds accessories such as forks, spoons, spouts, sponges, needles, straws with or without valves, measuring devices for doses, a pump and other utensils.
  • the pouches or sachets can find widespread use but in their preferred use as a component of a food and beverage container such as a baby bottle the material from which the pouch is made must have a very low permeability to oxygen and also low permeability to water vapour.
  • the permeability to oxygen of the material from which the pouch is made is no more than 0.8 and preferably no more than 0.01 and the permeability to water vapour is no more than 0.3.
  • the walls of the pouch are typically made from thermoplastic film and preferably have a tensile strength greater than 90N when the pouch is formed with hold points at either end of the sealed pouch.
  • the material should be flexible, stable and not expand at the temperatures at which the pouch may be used, they should also be resistant to any hot liquids that may be introduced into the pouch such as boiling water up to 100°C.
  • the external surface of the walls (preferably the underside wall) of the pouch are preferably printable to enable the provision of the measurement marks and may be advertising matter and the wall is preferably transparent at least at the position of the measurement marks.
  • the print should conform with standard BSEN 14350.
  • the pouch may be made from paper, cardboard or naturally derived materials such as natural recyclable barrier packaging material for food and drink such as Delipac TM the material can be selected according to the use to which the pouch or sachet is to be put.
  • the removable seal at the second end of the pouch should be such that the end of the pouch can be removed by hand and is conveniently provided by a tear line across the width of the pouch and near to the second end of the pouch.
  • a tear line When a tear line is used the line should be sufficiently strong to avoid unwanted opening of the pouch.
  • the tear line is extremely well defined so that when the removable seal is removed the open end of the pouch that is provided, provides a uniform preferably circular end to the pouch so that it can be accurately positioned and held between the slip ring and the holder of the holder system of this invention.
  • a tear line can be produced by employing a laser to define the tear line by cutting part way through the material used to make the pouch.
  • the pouch may be produced by folding a flat piece of film and forming a seal at the side and the bottom. Alternatively the pouch may be formed from two different pieces of material sealed together along the sides and at one end with the provision of a gusset at the sealed end of the pouch. If the pouch is to contain material such as powdered milk it will be introduced into the pouch through the open end which is then sealed to provide the removable seal and this may be provided automatically after the material has been introduced and the end sealed.
  • the tear line is usually positioned just below the seal.
  • the pouches are preferably produced on a continuous line where the appropriate material is provided and then continuously shaped and sealed at the sides and one end, any contents introduced into the pouch and a seal formed at the other end and the completed pouch cut from the material to allow the next pouch to be formed in the same manner.
  • a vertical form fill seal machine wherein the material is a single sheet on a reel which is folded in half and fed into the machine vertically from top to bottom and the gusset is formed on the folded edge of the material.
  • the material may be pre printed and pre laser cut to provide the tear line.
  • the laser cut lines are provided on both halves and are matched or aligned together and a seal created above the laser cut lines.
  • the pouch may be gas flushed when it is filled which not only preserves the content but makes it easier for a holder to be introduced into the mouth of the pouch when the tear strip has been removed from the pouch.
  • the same conditions may be preferred.
  • the pouch may be manufactured on a horizontal fill form machine, here the pouches are made horizontally, although this is not preferred as the volume capability is not as high and the machines take up a larger footprint.
  • the fill within the pouch may be an amount for further mixing such as with water to form the desired food or beverage or the pouch may be supplied filled to the required fluid level.
  • the two side seams of the preferred pouch assist in creating the supporting structure and if powder is introduced it can be gas flushed which helps form the cylindrical shape of the pouch when the tear seal is removed.
  • two laser cut points or dots may be introduced on the material at the fold line of the gusset at the first sealed end.
  • the pouches can be made from two sheets or one with a single side seam although two side seams (using a single folded sheet) are preferred.
  • Four side seams can be formed when creating a 'block bottom' or 'push pop' style pouch although we prefer the 'Doy style' pouch with a single gusset at the bottom and with two side seams and a single weld at the top which provides the most appropriate stability and uniformity.
  • any suitable material may be used to manufacture the pouch.
  • the material can have a thickness in the range of 40 ⁇ to 250 ⁇ and preferably between 100 ⁇ to 120 ⁇ with 102 ⁇ to 1 15 ⁇ being most preferred.
  • the material should have the desired permeability, strength, flexibility, transparency, sealability and printability. It may therefore be necessary to employ laminates of different materials each of which contributes a particular property.
  • the inner surface of the pouch may be of polyethylene in order to provide the high resistance to permeability of oxygen and water and also to provide sealability and the outer surface of the pouch may be of polypropylene to provide increased strength, printability whilst retaining flexibility.
  • Other materials that may be used include polyamide films and polyester films. Where the pouch is to be used for foodstuffs the materials need to satisfy the appropriate health requirements particularly in relation to any additives which may be present in the walls of the pouch which must not migrate into the contents of the pouch.
  • a preferred laminate from which the pouch is produced comprises an inner layer that is rough to create a good friction fit to the holder.
  • An inner layer comprising a polyethylene film coated with an ethylene vinyl alcohol copolymer to provide barrier properties preferably comprising two layers of polyethylene with the ethylene vinyl alcohol copolymer between them, the polyethylene having a seal initiation temperature of about 100°C is particularly useful.
  • Such a film of thickness of 50 to 100 ⁇ particularly 60 to 80 ⁇ being especially preferred as the inner layer.
  • the middle layer of the laminate is preferably a film of polyester such as polyethylene terephthalate coated with silica and an ethylene vinyl alcohol copolymer to provide further barrier properties.
  • this middle layer may be a three layer sandwich of two polyester layers with the silica and ethylene vinyl alcohol copolymer between them.
  • This middle layer is preferably of thickness 8 to 16 ⁇ more preferably 10 to 14 ⁇ .
  • the outer layer of the three layer laminate is preferably of oriented preferably transparent polypropylene to enable provision of the slip ring when used with the holder system.
  • the outer layer preferably has a thickness of 10 to 30 ⁇ more preferably 15 to 25 ⁇ .
  • the tear line may therefore be formed by cutting through the outer polypropylene layer and perhaps part of the middle polyester layer whilst leaving the inner layer intact and providing barrier properties.
  • alternative materials for manufacture of the pouch can include the barrier layer in the middle of the three layers only. Or, if two layers are used, the barrier layer can be on one or both of the layers. If only one barrier layer is used, preferably on the inside layer.
  • a print layer for pouch artwork including measurements and level indicators indicating content by liquid volume may be provided on the underside of the orientated polypropylene layer between the middle layer and outer layer.
  • the lamination of the layers is performed in the melt and is solvent free.
  • the laser cut line to produce the tear line is preferably through the orientated polypropylene layer and possibly into some of the polyester layer.
