  • the present disclosure relates to a container comprising two compartments on either side of a sealing layer, wherein the compartments are in registration such that the first compartment and the second compartment are separated only by the sealing layer having a rupturable zone.
  • the first and second compartments When the rupturable zone is ruptured, the first and second compartments come into fluid communication with one another in a combined compartment, which is defined by the volume of the first and second compartments combined (i.e. the first and second compartments together make up the combined compartment, and the contents of the first and second compartments are in fluid communication in the combined compartment).
  • sealing layer is meant a thin film of material that is capable of forming a seal with other materials, particularly polymeric materials such as thermoformable materials, on both its first and second side.
  • the sealing layer is capable of forming a seal by heat sealing.
  • the first and second seals are thus typically formed by heat sealing.
  • heat sealing inputting energy to cause an area of the sealing layer and/or first/second formed sections to increase in temperature allowing the seal to form.
  • the energy may be inputted by any means, for instance by pressing heated elements against the area (i.e. heat press sealing), via ultrasonic energy sources (i.e. ultrasonic bonding), via radiation (i.e. via a radiofrequency (RF) heat sealer), or induction heating (i.e. using induction to heat a metal component in the sealing layer, first or second formed section).
  • RF radiofrequency
  • first side or second side of the sealing layer is meant the planar surfaces of the sealing layer rather than the thin edge portions.
  • the first and second sides are the opposite faces of the sealing layer.
  • the sealing layer is bonded to the first/second formed sections via a first/second seal to form the first/second compartments respectively.
  • the seal forms a continuous loop which has an "inner perimeter” that is inside the first/second compartment, and an “outer perimeter” that is outside the first/second compartment.
  • at least one of the first or second seals is peelable, with the first seal most often being peelable.
  • peelable is meant capable of being pulled apart, such that the sealing layer can be peeled off the formed section.
  • the peel strength of a seal may be measured using ASTM F88, typically with a test speed of 100 mm/min, and usually with Technique A (unsupported).
  • Typical values for a peelable seal are below 30 N/15 mm, desirably below 20 N/15 mm, for example from 2 to 30 N/15 mm, or from 2 to 20 N/15 mm.
  • Peel strength values of from 2 to 6 N/15 mm are generally regarded as 'easy opening'. To ensure the container is not opened unintentionally (e.g. during transport), it is desirable that the peel strength is above these lower levels, e.g. above 5 N/15 mm, desirably above 6 N/15 mm or above 7 N/15 mm.
  • More desirable peel strength values are therefore from 5 to 20 N/15 mm, or from 6 to 15 N/15 mm or from 7 to 12 N/15 mm.
  • peel strength values for a typical 'tray' application e.g.
  • microwaveable food products are from 6 to 15 N/15 mm, more typically from 7 to 12 N/15 mm.
  • the first/second and combined compartments are water tight.
  • the first/second and combined compartments are water tight and air tight.
  • water tight is meant that liquids such as water cannot escape from the compartment, i.e. the compartments are sealed with no holes or openings which allow liquids to leak out.
  • air tight is meant that the compartment is sealed to be gas impermeable.
  • a gas impermeable material typically has an oxygen transmission rate as measured according to ASTM F1927 (in ml/m 2 /24 hrs measured at 23°C, 50% relative humidity) of below 100, more typically below 50, desirably below 20, more desirably below 10, even more desirably below 1.
  • Typical requirements for the oxygen transmission rate of packaging materials are below around 10 for fresh food, and below 0.5 for fruit juices or dried foods such as coffee, powdered milk.
  • a water tight material may further be characterised by its water vapour transmission rate (WVTR), for example as measured by ASTM F1249.
  • WVTR water vapour transmission rate
  • a water tight material typically has a WVTR as measured according to ASTM F1249 (in ml/m 2 /24 hrs measured at 25°C, 75% relative humidity) of below 10, more typically below 5, more typically below 2, desirably below 1.

  • the second compartment contains a second substance
  • the first and second substance can be solid, liquid or gas, typically solid or liquid, with liquids being the most commonly used. Typically, at least one of the first or second substances is a liquid.
  • Suitable first and second substances include food products, paints, adhesives, and healthcare/medical products.
  • the container disclosed herein allows the two substances to be stored isolated from one another, and then mixed prior to use in a controlled atmosphere and environment before the container is opened.
  • the rupturable zone that separates the first and second compartments acts as an easily rupturable membrane that, when broken, allows the first and second compartments to come into fluid communication with one another in a combined compartment.

  • the second substance is a vitamin or other food supplement.
  • the container disclosed herein allows the vitamins to be added to the juice just before it is served. In this way, acid sensitive
  • the first formed section typically contains a feature comprising a first recess and a first rim, wherein the entire perimeter of the first rim lies in a plane and the first recess is entirely on one side of that plane. In this way, when the first formed section is bonded to the sealing layer, the sealing layer can remain flat and form a seal with the entire perimeter of the first rim of the feature to form the first compartment from the first recess.
  • the second formed section also typically contains a feature comprising a second recess and a second rim, wherein the entire perimeter of the second rim lies in a plane and the second recess is entirely on one side of that plane.
  • the sealing layer can remain flat and form a seal with the entire perimeter of the second rim of the feature to form the second compartment from the second recess.
  • the flat rims allow the sealing layer to bond to the formed sections around the entire rim, this does not mean that the seal is always formed across the entire width of the rims. Indeed, often the first and/or second seal extend partially across the first/second rim.
  • An advantage of bonding the sealing layer only partially across the first/second rim is the sealing layer becomes easier to peal apart from the first/second formed section, facilitating easy opening of the container.
  • the first rim of the first formed section has an inner and outer perimeter, and the inner and outer perimeters of the first seal are congruent with or lie within the inner and outer perimeters of the first rim.

  • the first surface of the sealing layer is capable of bonding to the first formed section
  • second surface of the sealing layer is capable of bonding to the second formed section.
  • the sealing layer is a three layer composite film comprising a first bonding layer, a structural layer, and a second bonding layer.
  • the first and second bonding layers are the layers of the sealing film that are capable of forming the seal with the formed section.
  • the first and second bonding layers will typically be made from the same material. However, different materials may also be used. This is particularly suitable if the first and second formed sections are made from differing materials, such that the first and second bonding layers may be formulated from materials specifically suited to form seals with the first and second formed sections respectively.
  • the first and second bonding layers will be formed from a heat sealable material.
  • Typical heat sealable materials are polymers with a relatively low melting point (e.g. 80- 150°C, typically 100-130°C), such that when exposed to heat sealing conditions
  • the polymers melt and form a bond.
  • Suitable heat sealable materials include APET (amorphous polyethylene terephthalate), polyethylene and polypropylene, desirably polyethylene and polypropylene with polyethylene being particularly suitable.

  • An example of a sealing film containing different sealing layers comprises APET as one bonding layer (e.g. the first bonding layer), with polyethylene as the other bonding layer (e.g. the second bonding layer).
  • the structural layer of the sealing layer provides structural strength to the layer, so typically it is unaffected by heat sealing, and has relatively high tensile strength and tear strength.
  • the structural layer may also provide the barrier properties for the sealing layer, preventing the substances in the first and second compartments from mixing.
  • the barrier properties may be provided by an additional layer, such as a metalised (or foil) layer.

  • Exemplary materials for the structural layer include polyesters such as polyethylene terephthalate (PET, such as Ramapet N180 from UAB Indoramer Polymers), polyolefins such as polypropylene, and polyvinyl alcohols (such as Eval F104B from Eval Europe).
  • PET polyethylene terephthalate
  • polyolefins such as polypropylene
  • polyvinyl alcohols such as Eval F104B from Eval Europe
  • the structural layer is oriented to improve its strength.
  • the structural layer may be formed from oriented polyethylene terephthalate (O-PET, such as Mylar 800 from DuPont Teijin Films) or oriented polypropylene (O-PP).
  • the formed section may be made from a variety of materials, with the first and second formed section being made from the same or different materials.
  • the formed section comprises a polymeric material.
  • thermoformed section is meant a component that is formed into a three-dimensional shape, such that together with a sealing layer (which is typically planar) it may form an enclosure.
  • the formed section is formed by thermoforming a thermoformable material.
  • the formed section may be called a thermoformed section.
  • the formed section may also be formed by cold forming.
  • Cold forming is a process involving shaping or forming the material at or near room temperature. This type of process is commonly used to form blister packs in pharmaceuticals, and is therefore particularly suitable for forming the second formed section which is typically smaller.
  • the material used to form the formed section will be a multilayer material comprising a (thermo)formable layer, an optional barrier layer, and a bonding layer.
  • the bonding layer is the layer of the material that is capable of forming the seal with the sealing layer.

  • the first and/or second formed sections may also be formed by blow moulding, either prior to formation of the container as a separate manufacturing step, or as an integral step in the method of forming the container.
  • the first and second formed sections are bonded to the opposite sides of the sealing layer so as to be in registration with one another, such that the inner perimeter formed by the second seal is congruent with or lies within the outer perimeter formed by the second seal. This ensures that the first and second compartments are separated only by the sealing layer.
  • the inner perimeter formed by the second seal is congruent with or lies within the inner perimeter formed by the second seal.
  • the outer perimeter of the second seal may lie completely within the inner perimeter of the first seal. However, typically, the first and second seal overlap to some extent.
  • the outer perimeter of the second seal is congruent with the outer perimeter of the first seal.
  • the container may be difficult to open unless the first formed section, sealing layer or second formed section comprises a portion that extends beyond the first and second seals. This portion can then be gripped and used to pull apart the seal, enabling the sealing layer to be removed from the first or second formed section, opening the container to allow access to its contents.
  • opening the container is meant interfering with the integrity of the first, second or most typically combined compartment to allow the contents thereof to be accessed. Most typically, this is done by peeling apart the seal between the sealing layer and the first or second formed section.
  • the container is opened after the rupturable zone has been ruptured and the contents have been mixed in the combined compartment.
  • opening the container is therefore typically synonymous with “opening the combined compartment”.
  • the container may comprise a tab that allows the container (i.e. first, second or most typically combined compartment) to be opened by pealing apart the first and/or second seals.
  • the tab may be formed from the first formed section, second formed section, sealing layer, or any combination thereof. Typically, the tab is formed form a portion of the first formed section, section formed section and/or sealing layer that extends beyond the outer perimeter of the first and/or second seals.
  • the relative size and shape of the first and second compartments will mean that the first compartment is larger and will more naturally act as the base of the container, while the second compartment is smaller and effectively is located on the lid of the container, in which case the tab is typically formed from the sealing layer optionally together with the second formed section. This more easily allows the sealing layer to be peeled away from the first formed section, removing the 'lid' of the first compartment.
  • the tab could be formed from the sealing layer and second formed section that extends beyond the outer perimeter of the first seal.
  • the tab could be formed from a portion where the first formed section, sealing layer and second formed section are all in registration and congruent with one another, but the sealing layer is not bonded to the first formed section.
  • the sealing layer and second formed section may also extend beyond the outer perimeter of the rim of the first formed section.
  • Forming the tab from at least one of the first or second formed sections is advantageous, as these typically have a higher tensile and tear strength than the material used to form the sealing layer.
  • a tab formed from the sealing layer alone would typically not be strong enough, and there is a risk that such a tab may simply tear or break when it is pulled.
  • the tab is typically sized to allow it to be easily held by a person between their pinched fingers, such that a person may pinch the tab and peel the container apart.
  • the tab may comprise two flaps that are held with either hand, such that one flap is held with the left hand and one flap held with the right hand and the container is peeled apart.

  • the sealing layer furthermore comprises a rupturable zone in the area where the sealing layer separates the first and second compartments.
  • rupturable zone is meant an area where the sealing layer has been structurally compromised to reduce its strength, i.e. the rupturable zone is a structurally compromised area (an area of weakness) in the sealing layer which has reduced strength (e.g. tensile and/or tear strength) compared to the remainder of the sealing layer (i.e. compared the an area of the sealing layer that has not been structurally compromised).
  • the sealing layer is more easily broken in the rupturable zone, allowing the first and second compartment to come into fluid communication with one another (i.e. be formed into a single compartment) when the rupturable zone is broken.
  • the rupturable zone is an area of weakness (or an area where the sealing layer has been structurally compromised to reduce its strength) which is present in the sealing layer prior to use of the container.
  • the rupturable zone is an area of weakness which is present in the sealing layer during storage of the container, i.e. absent any external forces acting on the container.
  • the rupturable zone is an area of weakness which is present in the sealing layer while the first and second compartments are being sealed during formation of the container.
  • the rupturable zone is present in the sealing layer prior to its incorporation in the container.
  • the rupturable zone is formed by laser etching the sealing layer.
  • the rupturable zone may be formed by laser etching the sealing layer to remove the second bonding layer and at least part of the structural layer (typically all of the structural layer) of the sealing layer.
  • Suitable apparatus for laser etching films are known in the art.
  • the rupturable zone can in principle be any shape, such as a line, or more than one intersecting lines.
  • the rupturable zone could be in the form of an incomplete shape such as a crescent or three sided square, so as to form a flap that is capable of opening when the rupturable zone breaks.
  • the first and second compartments are combined into a single compartment (i.e. the combined compartment). However, this occurs without the first and second seals being compromised.
  • the first and second compartments therefore combine and allow mixing of their contents without the container as a whole being opened.
  • the rupturable zone is typically ruptured due to a build-up of pressure in the first or second compartment (most typically the second compartment).
  • the increased pressure causes the rupturable zone to break without compromising the first seal.
  • the rupturable zone is configured to rupture upon increase of pressure inside the first or second compartment (e.g. above a predetermined pressure) relative to the other compartment.
  • this increase in pressure is effected by a reduction in volume of the first or second compartment, which may occur when the first or second compartment is subjected to an external force such as by a person pressing their finger on the first or second compartment.
  • the rupturable zone is configured to rupture upon increase of pressure inside the first or second compartment (e.g. above a predetermined pressure) relative to the other compartment, said increase in pressure typically being caused by a reduction in volume of the first or second compartment.
  • the increase in pressure may be caused by the first or second compartment being deformed, for example by being squeezed or pressed by a person's finger.
  • the first and/or second formed section is typically formed from a

Instead, the sealing layer is ruptured solely due to the increase in pressure in the first or second compartment relative to the other compartment.
  • the predetermined pressure at which the sealing layer will rupture may be low enough to allow rupture of the sealing layer when finger pressure (i.e. finger push strength) is applied to the first or second compartment.
  • the predetermined pressure should ideally be high enough to avoid accidental rupture of the sealing layer, for instance if the container was accidentally bumped.
  • this corresponds to at least 25 N of force applied to the first or second compartment, more desirably at least 50 N of force applied to the first or second compartment, for instance at least 75 N of force applied to the first or second
  • the liquid components become forced through the rupture in the rupturable zone due to the increased pressure in the second compartment which occurs for example when a person presses on the second compartment with a finger.
  • the rupturable zone ruptures to leave a narrow opening. The pressure then forces the liquid through the narrow opening to form a spray, which facilitates rapid mixing with the contents of the first compartment.
