Abstract
A dose tape for use in a dry powder inhaler has blisters formed in a formpack layer. A lidstock layer is attached over the formpack layer, to seal a dose of dry powder within each of the blisters. A tear strip is attached to the lidstock layer over each of the blisters. Pulling on the tear strip shears out an area of the lidstock over the blister, unsealing the powder contents.
Claims26
A blister tape for use in an inhaler, comprising:
- a formpack layer;
- a plurality of blisters formed in the formpack layer;
- a dose of a pharmaceutical in each of the blisters;
- a lidstock layer attached to the formpack layer, with the lidstock layer sealing the dose within each of the blisters, wherein areas of the lidstock layer that are directly over the blisters form lidstock disks;
- and
- a tear strip attached to the lidstock disks, so that when the tear strip is pulled away from the formpack layer, one of the lidstock disks shears out of the lidstock layer to completely unseal a corresponding one of the blisters.
A dose tape for providing multiple doses of a pharmaceutical via an inhaler, comprising:
- a first tape layer;
- a plurality of dose wells equally spaced apart in the first tape layer and defining dose well apertures;
- a dose of a dry powder pharmaceutical in substantially each of the dose wells;
- a shearable second layer attached to the first layer in between the dose wells, with the second layer and the first layer confining the dose of dry powder within each of the dose wells;
- and
- a shear strip attached to the second layer over each of the dose wells, and with the shear strip not attached to the second layer between each of the dose wells, such that the shear strip is attached to the second layer via local attachment zones located over each dose well with unattached zones located between dose wells and the local attachment zones along the length of the tape.

- a shearable second layer attached to the first layer in between the dose wells, with the second layer and the first layer confining the dose of dry powder within each of the dose wells;
- and
- a shear strip attached to the second layer over each of the dose wells with the shear strip not attached to the second layer between each of the dose wells, such that the shear strip is attached to the second layer at intermittent locations corresponding to the dose wells where the shear strip is secured to the second layer and such that gaps between the shear strip and the second layer remain between the intermittent locations.
