Title: Automatic collector of the tips on phials of orally taken medicinal products and other liquids
IPC: A61J1/06
Filed: 1986-12-01
Abstract: The invention relates to a device fixed on the phials 1 allowing the tips 4 which are broken on use to be collected automatically and removed 5 away from the emptying hole. It facilitates the use of phials, prevents the tips being scattered, and eliminates the risks stemming therefrom. The device consists of tensioned elastic ties 2, one end of which is anchored on the tip 7 and the other is fixed to the body of the phial. When a tip 4 is broken, the tie 2 retracts 11, takes with it the tip which is trapped, and is stowed, with the tip, away from the emptying hole 6.
