• a spring member positioned to act on the indicator member,
• wherein the indicator member is moved or rotated stepwise by the force of the spring.

Nebulizer for a fluid, comprising:

• a replaceable container containing the fluid,
• a device for counting the number of containers that have been used or still can be used,
• an indicator member displaying said number, and
• a lock for preventing operation of the nebulizer,
• wherein the indicator member drives the lock such that the nebulizer is locked against further use in a first locked state when the container needs to be replaced, and wherein the first locked state is resettable by indexing the indicator member when the container has been replaced.

Nebulizer for a fluid, comprising:

• a replaceable container containing a fluid,
• a lock for locking the nebulizer against further use in a first locked state when a container needs to be replaced, the first locked state being resettable by resetting the lock when the container has been replaced,
• a control member for controlling or driving the lock, and
• a spring adapted for rotating the control member in stepwise manner.

Nebulizer for a fluid, comprising:

• a replaceable container containing a fluid,
• a lock for locking the nebulizer against further use in a first locked state when the container needs to be replaced, the first locked state being resettable by resetting the lock when the container has been replaced, and
• a control member for controlling or driving the lock,
• wherein the lock is blocked against resetting when in a second locked state once a predetermined number of containers has been used or inserted into the nebulizer.

Nebulizer for a fluid, comprising:

• a replaceable container containing a fluid, and
• a housing part which can be detached or opened for replacing the container, and
• a securing device associated with the container for preventing a used container from being connected to the nebulizer,
• wherein the securing device comprises locking portions that are moveable radially at least after the used container has been detached from the nebulizer such that the used container cannot be re-connected to the nebulizer.

Nebulizer for a fluid, comprising:

• a replaceable container containing a fluid,
• a device for counting at least one of the number of containers that have been used and the number of containers that still can be used, and
• an indicator member having a series of numerals for displaying said numbers and at least one symbol for indicating container replacement,
• wherein the indicator member is adapted to show different numerals alternately with the at least one symbol indicating container replacement.

Nebulizer for a fluid, comprising:

• a replaceable container containing a fluid,
• a device for counting at least one of the numbers of containers that have been used and the numbers of containers that still can be used, and
• an indicator member having a series of numerals for indicating said numbers and at least two symbols of which a first symbol indicates opening of the nebulizer for container replacement and a second symbol indicates closing of the nebulizer to complete container replacement,
• wherein indicator member is adapted to show different numerals alternately with a sequence of said first and second symbols.
