Definitions

  • the invention relates to a blister pack from which a medicament can be dispensed, particularly to a blister pack which incorporates features to render the blister pack resistant to a child accessing a medicament stored in said pack.
  • a blister pack comprises a formed layer which includes cavities, within which a medicament such as a tablet or capsule can be stored, and a lid that substantially seals the cavities so that the lid must be removed and/or broken in order to access the medicament therein.

  • a lid that substantially seals the cavities so that the lid must be removed and/or broken in order to access the medicament therein.
  • Such blister packs are useful in that each cavity can contain a single dose of a medication which is substantially sealed until use. However it can be easy for a child to gain access to the medication within such blister packs which could result in harm if potentially toxic medication was ingested or if the medication was incorrectly used.
  • the present invention provides a blister pack for storing a medicament and from which said medicament can be dispensed, the blister pack comprising at least a formed layer and a lid, the formed layer including at least one cavity within which a medicament can be located, the cavity having an opening in a first side of the formed layer and a protrusion from an opposing side of the formed layer, the blister pack having a tab portion and an opening portion, the opening portion comprising at least the opening, the blister pack being arranged such that within the opening portion the lid substantially covers the opening on the first side of the formed layer and is at least partially removable, in the tab portion a tab, comprising at least some of the lid, is coupled to the formed layer by one or more breakable connections such that the tab is not readily accessible, the one or more breakable connections are breakable by a user so that a user can access the tab and apply a removal force thereto so as to initiate removal of at least some of the lid from the opening portion, the lid including guide portions, the guide portions comprising pre-formed weaknesses and extending along opposite sides of
  • the blister pack may comprise one or more cavities. Each cavity can have an associated tab portion and opening portion and each cavity can contain a medicament. Each cavity may be separately accessible, or a single opening portion could include more than one cavity opening and a single tab could be arranged to initiate removal of at least some of the lid across said opening portion to permit access to all of the cavities covered thereby.
  • the formed layer can be fabricated from any suitable material, for example aluminium foil, a plastics material or a laminated material which may comprise one, both or neither of these materials.
  • the material may allow a user to deform the cavity by pushing the protruding portion towards the first surface as this can aid removal of the medicament contained in said cavity by forcing it toward and/or through the opening.
  • the protrusion can be any suitable shape, for example the protrusion may be shaped substantially like a portion of a sphere with a substantially circular opening, or a substantially like a portion of a cylinder with rounded ends which would have an opening that was substantially rectangular, but with rounded ends .
  • the lid can be fabricated from any suitable material, for example aluminium foil, a plastics material or a laminated material which may comprise one, both or neither of these materials.
  • the lid may comprise a plurality of layers bonded together, each layer may have different mechanical and/or physical properties.
  • the layers may be separable.
  • the lid is applied to the formed layer as a sheet during manufacture.

Breakable connections can also be formed by cutting the lid and/or the formed layer along a line around at least a portion of a periphery of the tab, but leaving one or more bridges of uncut lid and/or formed layer material between the tab and an adjacent part of the blister pack. Such connections can be formed by perforating along the line around at least a portion of a periphery of the tab. The bridges will act to concentrate any stress applied and should be sized to be breakable by a user.
  • the tab is substantially retained in a position with respect to the formed layer such that it is not readily accessible when the connections are intact, once broken by a user the tab can be more easily displaced away from the formed layer so that the tab is more readily accessible.

  • the guide portions may include a divergent portion adjacent the tab where a narrow peel initiated from the tab is made wider and then a substantially parallel portion in which the guide portions guide the peel so that at least some of the lid ' is removed from the opening portion to allow either access to the medication or the medication to be pushed through the intermediate layer.
  • the intermediate layer may be breakable by a user pushing something into the cavity through the intermediate layer, but in one embodiment is breakable by a user applying a 1 deformation force to the cavity and causing the medicament to be forced through the intermediate layer.
  • the blister pack may be arranged such that when the lidding layer has not been removed from the opening portion the lidding layer substantially prevents rupture of the intermediate layer by such mechanisms. In this way a sequence of operations must be performed in order to gain access to the medication in the blister.
