Abstract

The invention relates to a protective cap for a dispenser, and to a dispenser for discharging pharmaceutical and/or cosmetical liquids, wherein the dispenser has a liquid reservoir and an outlet opening through which the liquid can be discharged into a surrounding atmosphere. The protective cap comprises an outer cap and an inner element inserted therein, wherein either at least one ventilation channel, which can be closed by means of a shut-off element and provides communication between an interior of the protective cap and an external environment, is formed between the outer cap and the inner element, or the inner element closes a ventilation opening of the outer cap.

First claim

The invention claimed is:

1. A protective cap for a dispenser for discharging a pharmaceutical and/or cosmetical liquid having a liquid reservoir and an outlet opening through which the liquid can be discharged into a surrounding atmosphere, the protective cap comprising:
an outer cap and an inner element inserted therein;
at least one ventilation channel providing communication between an interior of the protective cap and an external environment formed between the outer cap and the inner element; and
a tamper-evident safety device with a first segment which is to be removed irreversibly before a first use, wherein the first segment to be removed serves as a shut-off element which is to be separated irreversibly from the protective cap before the first use and by which the at least one ventilation channel is directly closed in an airtight and germproof manner by the first segment before removal of the first segment, wherein the shut-off element directly prevents airflow through the at least one ventilation channel before removal of the shut-off element.

2. The protective cap as claimed in claim 1 , wherein the tamper-evident safety device has the first segment and a second segment, wherein the first segment is connected to the second segment and to the outer cap by predetermined breaking points.

3. The protective cap as claimed in claim 1 , wherein the inner element has two sealing areas which are spaced apart in an axial direction and are for providing contact with the dispenser.

4. The protective cap as claimed in claim 1 , wherein the protective cap has an absorber element that rests on the outlet opening during use.

5. A discharge device comprising:
a dispenser for discharging a pharmaceutical and/or cosmetical liquid, the dispenser including a liquid reservoir and an outlet opening through which the liquid can be discharged into a surrounding atmosphere; and
a protective cap with an outer cap and an inner element inserted therein, wherein at least one ventilation channel providing communication between an interior of the protective cap and an external environment is formed between the outer cap and the inner element, and a tamper-evident safety device with a first segment which is to be removed irreversibly before a first use, wherein the first segment to be removed serves as a shut-off element which is to be separated irreversibly from the protective cap before the first use and by which the at least one ventilation channel is directly closed in an airtight and germproof manner by the first segment before removal of the first segment, wherein the shut-off element directly prevents airflow through the at least one ventilation channel before removal of the shut-off element.

6. The discharge device as claimed in claim 5 , wherein the first segment, before a removal, bears sealingly in the airtight and germproof manner on a housing of the dispenser such that the at least one ventilation channel is directly closed in the airtight and germproof manner by the first segment before removal of the first segment.

7. The discharge device as claimed in claim 5 , further comprising an outlet channel, which connects the liquid reservoir to the outlet opening, and an outlet valve, which opens depending on pressure or can be manually actuated and which is arranged in the outlet channel and, in a closed state, closes the outlet channel.

8. The discharge device as claimed in claim 5 , wherein the shut-off element is connected to the outer cap by predetermined breaking points.

9. A protective cap for a dispenser comprising:
an outer cap and an inner element inserted therein;
at least one ventilation channel providing communication between an interior of the protective cap and an external environment formed between the outer cap and the inner element; and
a tamper-evident safety device with a first segment which is to be removed irreversibly before a first use of the protective cap, wherein the first segment to be removed serves as a shut-off element which is to be separated irreversibly from the protective cap before the first use and by which the at least one ventilation channel is directly closed in an airtight and germproof manner while the shut-off element is connected to the protective cap;
wherein the shut-off element directly prevents airflow through the at least one ventilation channel before removal of the shut-off element.

10. The protective cap of claim 9 , wherein the shut-off element is connected to the outer cap by predetermined breaking points.
