Vacuum-closed cap provided with a device to open containers completely

Abstract

A vacuum-closed cap provided with a device to open containers completely designed to allow the release of the inner pressure of the container ( 2 ) so that it can be opened later on, said cap ( 1 ) being fully removed therefrom and being comprised of a gripping ring ( 3 ), attached through its front tab ( 4 ) to a shoulder ( 5 ) on its surface ( 6 ), said shoulder ( 5 ) being provided with a slit ( 7 ) in the junction between same and the surface ( 6 ) of the cap ( 1 ), in such a way that, when the tab ( 3 ) is manually pressed vertically upward, it reveals an orifice ( 8 ) caused by the disruption of said slit ( 9 ), said cap ( 1 ) being provided with shoulders or claws ( 9 ) which, during the filling process, are coupled to the packing wire ( 2 ) or the lip ( 10 ) thereof, thus attaining a perfect coupling between both the container ( 2 ) and the cap ( 1 ).

1 . A vacuum-closed cap provided with a device to open containers completely, characterized by comprising a cap ( 1 ) that allows the release of the inner pressure of containers ( 2 ) so that they can be opened, through the orifice ( 8 ) of said cap ( 1 ), what can be done by means of a slit ( 7 ) adjacent to a shoulder ( 5 ) on the surface ( 6 ) thereof, by moving its gripping ring ( 3 ) vertically upward, which ring is attached through its front tab ( 4 ) to said shoulder ( 5 ).  
     
     
         2 . The vacuum-closed cap provided with a device to open containers completely according to  claim 1 , characterized in that the cap ( 1 ) fits the container ( 2 ) through claws or shoulders ( 9 ) during the filling process, being coupled to the packing wire ( 2 ) or the lip ( 10 ) thereof.
