Definitions

• the invention relates to a device for dispensing a liquid, preferably an aqueous solution, comprising a vessel for containing the liquid, a dispensing dropper, a cap and a tamper-evident unit.
• ophthalmic liquids like ophthalmic drugs or contact lens solution.
• said vessel is designed to store liquid in the range between 2,5 ml and 50 ml, preferably between 5 ml and 15 ml. This may have the advantage that the device may be used as a primary packaging for ophthalmic solutions and/or for contact lens solutions.
• said first ring comprises at least one snap-on element and wherein the cap comprises at least one projection and wherein the snap-on element engages behind said at least one projection of the cap to fasten the first ring to the cap.
• said second ring is form-fit and/or force-fit to the vessel. This may allow for an easy attachment of the tamper-evident unit to the vessel.
• said second ring comprises at least one snap-on element and wherein the vessel comprises at least one projection and wherein the snap-on element engages behind said at least one projection of the vessel to fasten the second ring to the vessel.
• said cap comprises a polymer, preferably a high density polyethylene, HDPE, and/or wherein the dispensing dropper comprises a polymer, preferably a low density polyethylene, LDPE, and/or wherein the vessel comprises a polymer, preferably a low density polyethylene, LDPE, and/or wherein the tamper-evident unit comprises a polymer, preferably a low density polyethylene, LDPE.
• the dispensing dropper comprises a polymer, preferably a low density polyethylene, LDPE
• the vessel comprises a polymer, preferably a low density polyethylene, LDPE
• the tamper-evident unit comprises a polymer, preferably a low density polyethylene, LDPE.
• the invention relates to a method for opening a device for dispensing a liquid, preferably a device according to any one of claims 1 to 14, comprising the steps:
• Figure 1 shows in a side view a tamper-evident unit and a device for dispensing a liquid, whereas the tamper-evident unit is unbroken or original, i.e. the cap has not been opened yet for the first time
• Figure 2 shows in a side view the tamper-evident unit and the device for dispensing a liquid of Figure 1 , whereas the cap is partly detached from the vessel but not yet in its final open position
• Figures 3 shows in a side view the tamper-evident unit and the device for dispensing a liquid of Figure 1 , whereas the cap is in a tilted, final open position.
• a device for dispensing a liquid comprising a vessel 1 for containing the liquid, a dispensing dropper 2, a cap 3 and a tamper-evident unit 4.
• the tamper-evident unit 4 has a first ring 5, a second ring 6 and two elastic elements 7, 8 for connecting the first ring 5 to the second ring 6.
• the first ring 5 is connected to the cap 3 and the second ring 6 is connected to the vessel 1.
• the tamper-evident unit 4 comprises tamper-evident connecting elements 9 that are arranged between the first ring 5 and the second ring 6.
• the tamper-evident connecting elements 9 are configured such to break off, when the cap 3 is opened for the first time.
• the second ring 6 comprises snap-on elements 19 and the vessel 1 comprises at least one projection 20. Therefore, the snap-on element 19 engages behind said at least one projection 20 of the vessel 3 to fasten the second ring 6 to the vessel 1.
• the contents of the bottle or vessel 1 are in particular only indirectly protected from contamination by the invention.
• the invention in particular protects the dropper 2 and the cap 3 from contamination, as the cap 3 cannot fall off and the dropper 2 can always be securely protected with the cap 3.
• At least one embodiment may provide at least one of the following features and/or at least one of the following advantages:
