## Abstract

An inhaler for delivery of a powder-form inhalation formulation from a blister strip with a plurality of blister pockets is proposed. A flexible guiding element receives the used blisters strip.

## Claims

### Claim 1

Inhaler for delivery of an inhalation formulation from a band-shaped blister strip with a plurality of blister pockets containing the inhalation formulation in doses, comprising:
a piercing member to puncture a lid of an aligned blister pocket, the inhaler being designed such that—by breathing in during inhalation—an air stream of ambient air can be sucked or delivered in to discharge the respective dose from an opened blister pocket and to deliver it with the ambient air as an aerosol cloud,
wherein
the inhaler comprises a flexible or elastic guiding element for receiving or guiding a used portion of the blister strip, wherein
the guiding element comprises a mounting portion with a corrugation,
the mounting portion is held between a first and a second holding portion,
the guiding element or mounting portion is at least partially covered by a guiding portion.

### Claim 2 (depends on 1)

Inhaler according to claim 1, wherein the guiding element is made of steel.

### Claim 3 (depends on 1)

Inhaler according to claim 1, wherein the first and second holding portion are molded and are formed by a housing of the inhaler or by separate halves of the housing.

### Claim 4 (depends on 1)

Inhaler according to claim 1, wherein the first and second holding portion are at least essentially complementary.

### Claim 5 (depends on 1)

Inhaler according to claim 1, wherein the first and second holding portion form a slit in between for receiving the guiding element or the mounting portion.

### Claim 6 (depends on 1)

Inhaler according to claim 1, wherein the first or second holding portion forms the guiding portion.

### Claim 7 (depends on 1)

Inhaler according to claim 1, wherein the guiding portion is inclined or ramp-like to facilitate conveying the blister strip into the guiding element.

### Claim 8 (depends on 1)

Inhaler according to claim 1, wherein the guiding element comprises a free end having a slit with two tip or two tapered portions so that the guiding element comprises the highest curvature, flexibility or elasticity at the free end of the guiding element.
