Definitions

  • This invention relates to a lid for a container. More particularly, but not exclusively, the invention relates to a drink-through or consume-through lid for a sealed container of a drink or food product to facilitate opening of the container for consumption directly from the container. BACKGROUND OF THE INVENTION
  • the applicant has determined that it would be advantageous to provide a container which has the benefit of maintaining the contents fresh in a sealed condition, but which also provides convenient opening and comfortable consumption.
  • Examples of the present invention seek to avoid or at least ameliorate the disadvantages of existing sealed beverage containers.
  • the container has a seal
  • the closure includes a coupling arranged for holding the closure to the sealed container, and a tab adapted to be pressed toward the container so as to pivot away from a surrounding portion of the closure, wherein the tab includes an abutment which, during pressing of the tab, abuts the seal of the sealed container and presses against the seal so as to initiate mechanical piercing of the seal.
  • the closure includes frangible holding portions which, in an unused condition, hold the tab relative to the surrounding portion of the closure and which, in a deployed condition, are broken to allow the tab to be pushed below the surrounding portion. More preferably, the frangible holding portions are adapted to break visually so as to act as a tamper evident indicator.
  • the tab is pivotally movable between the unused and the deployed conditions about a hinge.
  • the closure is unitary in construction and the hinge is integrally formed in the unitary closure.
  • the abutment is configured to concentrate force on a relatively small surface area of the seal. More preferably, the abutment is located centrally on an underside of the tab. Even more preferably, the abutment extends to a distal tip of the tab.
  • the abutment includes a downwardly-facing point. More preferably, the abutment is in the form of a longitudinal ridge extending perpendicular to the hinge.
  • the closure includes a perimetral lip for sealing against the mouth of a user. More preferably, the perimetral lip is in the form of a circular lip having a substantially planar upper edge.
  • the seal may be in the form of a membrane or film. More preferably, the seal is in the form of a foil membrane or a plastic induction-seal membrane.
  • the closure includes locking protrusions which resiliently engage to hold the tab in the deployed condition relative to the surrounding portion of the closure. More preferably, the locking protrusions are mounted at opposed sides of the tab.
  • the tab has an indentation on an upper surface thereof for receiving a finger or thumb of a user. More preferably, the protrusions are located between the indentation and the hinge.
  • closure includes a well and the tab is located within the well.
  • the tab is radial and a distal tip of the tab terminates near the perimetral lip.
  • the coupling is in the form of a resiliency deformable flange/shroud adapted to resiliently fit over a rim of the container.
  • the tab protrudes above the surrounding portion of the closure. More preferably, in the deployed condition, the tab is at or below the surrounding portion of the closure.
  • Figure 1 is a perspective view of a container fitted with a lid in accordance with an example of the invention ;
  • Figure 2 shows a top perspective view of the lid, as well as a cutaway view of the lid when fitted to a container, shown in an unused condition ;

  • Figure 15 shows top, bottom, left, right and front views of the lid of Figure 8, shown in the unused condition.
  • a lid 10 in accordance with an example of the present invention.
  • the lid 10 has a frangible tab which is able to be pressed downwardly from the lid to initiate mechanical piercing of a seal membrane over a container to which the lid is fitted.
  • the sipper lid shown in the drawings includes features which eliminate the need to remove a seal membrane from a pre-sealed beverage cup prior to dispensing/drinking the contents. This is achieved as the push/pierce mechanism is configured to receive pressure from a user's finger on the movable tab which then moves downwardly into contact with the seal membrane to initiate mechanical tearing of the seal membrane underneath.
  • a lid 10 for a sealed container of a food or drink product to facilitate opening of the container 12 for consumption by a consumer directly from the container 12.
  • the container 12 has a seal 14 (see Figures 2 to 4) .
  • the lid 10 includes a coupling 16 arranged for holding the lid 10 to the sealed container 12, and a tab 18 adapted to be pressed toward the container 12 so as to pivot away from a surrounding portion 20 of the lid 10.
  • the tab 18 includes an abutment 22 (see Figure 2) which, during pressing of the tab 18, abuts the seal 14 of the sealed container 12 and presses against the seal 14 so as to initiate mechanical piercing of the seal 14.
  • the lid 10 includes frangible holding portions 24 which, in an unused condition (see Figure 2), hold the tab 18 relative to the surrounding portion 20 of the lid 10 and which, in a deployed condition (see Figure 3), are broken to allow the tab 18 to be pushed below the surrounding portion 20.
  • the frangi ble holding portions 24 are adapted to break visually so as to act as a tamper evident indicator.
  • the tab 18 is pivotally movable between the unused and the deployed conditions about a hinge 26.
  • the lid 10 is unitary in construction and the hinge 26 is integrally formed in the unitary lid 10.
  • Figures 2 and 3 show clearly the mechanical piercing of the seal 14 as the tab 18 is moved from the unused condition shown in Figure 2 to the deployed condition shown in Figure 3.
  • the abutment 22 is configured to concentrate force on a relatively small surface area of the seal 14.
  • the abutment 22 is located centrally on an underside of the tab 18 and may extend to a distal tip 28 of the tab 18.
  • the abutment 22 may include a downwardly-facing point 30 (see Figure 4).
  • the abutment 22 may be in the form of a longitudinal ridge extending perpendicular to the hinge 26.
  • the lid 10 may include a perimetral lip 32 for sealing against the mouth of a user.
  • the perimetral lip 32 may be in the form of a circular lip having a substantially planar upper edge.
  • the edge of the lip 32 may be all on the same plane, this may facilitate for a membrane seal over the lid 10, if required.
  • the lid 10 includes locking protrusions 34 (see Figure 6) which resiliently engage to hold the tab 18 in the deployed condition relative to the surrounding portion 20 of the lid 10.
  • the locking protrusions 34 may be mounted at opposed sides of the tab 18, and the surrounding portion 20 of the lid 10 may be resiliently deformable so as to allow the locking protrusions 34 to move past and into the locking condition shown in the lower drawing of Figure 6.
  • the seal 14 may be in the form of a membrane or film and, more specifically, a foil membrane or a plastic induction seal membrane. A diagrammatic depiction of the seal 14 when mechanically pierced is shown in Figures 3 and 4.
  • the tab 18 may have an indentation 36 on an upper surface 38 thereof for receiving a finger or thumb of a user.
  • the indentation 36 may assist with positively locating the finger or thumb of the user so as not to slip on the tab 18 during opening.
  • the locking protrusions 34 may be located between the indentation 36 and the hinge 26 to make use of mechanical advantage in the lever arm of the tab 18.
  • the lid 10 may include a well 40 with the tab 18 being located within the well 40.
  • the well 40 may provide a relieved area for the nose of the user when drinking.
  • the well 40 may also be provided with a generally circular surrounding recess for vertical pack stacking.
  • the tab 18 is generally radial of the lid 10 and a distal tip 28 of the tab 18 terminates near the perimetral lip 32.
  • the coupling 16 may be in the form of a resiliently deformable flange/shroud 42 adapted to resiliently fit over a rim of the container 12.
  • the locking protrusions 34 may be tapered outwardly into an upper platform to facilitate movement of the tab 18 past the surrounding portion 20 and to encourage secure locking of the tab in the deployed condition.
  • the lid 10 may be arranged to be compatible with existing generic containers.
  • the push/pierce sipper lid with the push/pierce mechanism tab is designed to be moulded in plastic, and includes frangible sections designed to fail or break and to allow the tab to be folded inwards and clear of the drinking area of the lid.
  • the push/pierce mechanism tab also includes locking protrusions (or "pips") which effectively keep the tab in the open (deployed) state allowing unhindered pouring or drinking from the lid.
  • the push/pierce mechanism tab remains connected to the lid via the hinge so that even in the fully activated position the risk of breaking off the tab and it becoming a foreign matter hazard is eliminated/minimised.
  • FIGS 8 to 15 show a lid 10 in accordance with an alternative example of the present invention.
  • the lid 10 shown in Figures 8 to 15 is generally similar to the lid 10 of Figures 1 to 7, and like features are shown with like reference numerals.
  • the main differences with the lid 10 of Figures 8 to 15 include that the frangible break feature is in the form of a central frangible holding portion 24 which is located at a distal end of the tab along a central axis of the tab 18 which central axis is perpendicular to the hinge 26 about which the tab pivots.
  • the frangible holding portion 24 holds the tab 18 relative to the surrounding portion 20 of the lid 10.
  • the frangible holding portion 24 is broken to allow the tab 18 to be pushed below the surrounding portion 20.
  • the frangible holding portion 24 may be adapted to break visually so as to act as a tamper evident indicator.
  • the tab 18 is pivotally movable between the unused and the deployed conditions about the hinge 26.
  • the lid 10 is unitary in construction and the hinge 26 is integrally formed in the unitary lid 10.
  • the lid 10 includes a locking protrusion 34 having an over-centre arrangement across the hinge 26.
  • the over-centre arrangement includes a first flap depending from the lid 10 and a second flap depending from the tab 18, the first flap being arranged to resiliently snap past the second flap as the tab 18 is hingedly moved to the deployed condition, see detail in Figure 11.
  • the first and second flaps are centred along a central axis of the lid 10, which central axis extends along a centre of the tab 18 and perpendicular to the hinge 26.
  • the second flap may have at its distal end a cam to assist with the second flap riding along an upper surface of the first flap as the tab 18 is moved from the unused condition to the deployed condition.
  • the first flap may also include a distal recess on an underside thereof for accommodating the distal tip of the second flap when the tab 18 is in the deployed condition.
  • the lid may be referred to as a push- pierce lid (see Figure 8) ; the lid may be fitted to a generic beverage cup (see Figure 8); by applying downwards force with a finger of a user, the tab will initiate mechanical piercing of the seal membrane (see Figure 9) ; the push-pierce tab is designed to pierce through the planar seal membrane (see Figure 10); the frangible section of the tab is designed to fail or break offering both tamper-evidence and feedback to the consumer that the tab is being activated (see Figure 12 in which the tab has pierced the foil in the upper drawing and in which the frangible feature is broken away in the lower drawing); there is a "stop” designed to effectively lock the tab in the activated or fully opened position (see upper drawing of Figure 13); the tab is locked in the activated position in the lower drawing of Figure 13.
  • Figure 14 shows the lid 10 includes a recess 44 for vertical pack stacking, a relieved area 46 for the nose of the user when drinking, a stop feature to lock the activated tab in the open position, a frangible break feature as evidence of opening/tamper, and a raised drinking edge/lip 48.
  • Figure 15 shows a top view 50 of the lid shown in Figures 8 to 14, a bottom view 52, a left view 54, a right view 56, and a front view 58.
