Abstract

A lid for an opening device for a container includes a body having a longitudinal axis and provided with an end wall and with a side wall internally provided with a thread element suitable for cooperating with a further thread element of a spout of the opening device, the lid further includes at least one driving element having a first side arranged to receive the fingers of a user during unscrewing of the lid from the spout and a second side arranged for receiving the fingers of a user during screwing of the lid on the spout, the first side being defined by a wall and the second side being defined by a cavity.

First claim

The invention claimed is:

1. A lid for an opening device ( 1 ) for a container ( 100 ), comprising a body ( 25 ) having a longitudinal axis (B) and provided with an end wall ( 27 ) and with a side wall ( 28 ) internally provided with a thread element ( 29 ) suitable for cooperating with a further thread element ( 30 ) of a spout ( 12 ) of said opening device ( 1 ), said lid ( 18 ) further comprising at least one driving element ( 50 ) having a first side ( 51 ) arranged to receive the fingers of a user during unscrewing of said lid ( 18 ) from said spout ( 12 ) and a second side ( 52 ) arranged for receiving the fingers of a user during screwing of said lid ( 18 ) on said spout ( 12 ), said first side ( 51 ) being defined by a wall ( 58 ; 58 ′) and said second side ( 52 ) being defined by a cavity ( 59 );
wherein said at least one driving element ( 50 ) is delimited by an upper wall ( 56 ) and by a lower wall ( 57 ) extending from said side wall ( 28 ) and spaced apart from each other along said longitudinal axis (B); and
wherein said cavity ( 59 ) is recessed in relation to said upper wall ( 56 ) and said lower wall ( 57 ).

2. A lid according to claim 1 , wherein a gap ( 66 ) is interposed between said wall ( 58 ′) and said side wall ( 28 ).

3. A lid according to claim 1 , wherein said wall ( 58 ) extends from said side wall ( 28 ).

4. A lid according to claim 1 , wherein said at least one driving element ( 50 ) defines an appendix ( 55 ) radially projecting from said body ( 25 ).

5. A lid according to claim 1 , wherein said wall ( 58 ; 58 ′) extends between said upper wall ( 56 ) and said lower wall ( 57 ).

6. A lid according to claim 1 , wherein said cavity ( 59 ) is delimited by said upper wall ( 56 ), by said lower wall ( 57 ) and by an end edge ( 60 ) of said wall ( 58 ; 58 ′) arranged further away from said side wall ( 28 ).

7. A lid according to claim 1 , wherein said lid ( 18 ) comprises two driving elements ( 50 ) positioned at diametrically opposed locations on said body ( 25 ).

8. A lid according to claim 2 , wherein said at least one driving element ( 50 ) defines an appendix ( 55 ) radially projecting from said body ( 25 ).

9. A lid according to claim 3 , wherein said at least one driving element ( 50 ) defines an appendix ( 55 ) radially projecting from said body ( 25 ).

10. A lid for an opening device ( 1 ) for a container ( 100 ), comprising a body ( 25 ) having a longitudinal axis (B) and provided with an end wall ( 27 ) and with a side wall ( 28 ) internally provided with a thread element ( 29 ) suitable for cooperating with a further thread element ( 30 ) of a spout ( 12 ) of said opening device ( 1 ), said lid ( 18 ) further comprising at least one driving element ( 50 ) having a first side ( 51 ) arranged to receive the fingers of a user during unscrewing of said lid ( 18 ) from said spout ( 12 ) and a second side ( 52 ) arranged for receiving the fingers of a user during screwing of said lid ( 18 ) on said spout ( 12 ), said first side ( 51 ) being defined by a wall ( 58 ; 58 ′) and said second side ( 52 ) being defined by a cavity ( 59 );
wherein said at least one driving element ( 50 ) is delimited by an upper wall ( 56 ) and by a lower wall ( 57 ) extending from said side wall ( 28 ) and spaced apart from each other along said longitudinal axis (B); and
wherein said lower wall ( 57 ) diverges from said upper wall ( 56 ) when moving away from said side wall ( 28 ).

11. A lid according to claim 10 , wherein said upper wall ( 56 ) is substantially straight and said lower wall ( 57 ) is curved.

12. A lid according to claim 10 , wherein said upper wall ( 56 ) is substantially parallel to said end wall ( 27 ) and perpendicular to said longitudinal axis (B).

13. A lid according to claim 10 , wherein said at least one driving element ( 50 ) has an outmost portion ( 61 ), defined by the part of said lower wall ( 57 ) that is arranged further away from said side wall ( 28 ), which is substantially aligned with a lowermost border ( 62 ) of said lid ( 18 ).

14. A lid according to claim 13 , wherein said lowermost border ( 62 ) is an end edge of a tamper ring ( 201 ) connected to said body ( 25 ) by means of a breakable arrangement ( 202 ).

15. A lid according to claim 1 , wherein said side wall ( 28 ) comprises a knurling ( 63 ) arranged to provide a grip between the fingers of a user and said side wall ( 28 ), said knurling ( 63 ) having a height (h), measured along said longitudinal axis (B), which increases in an unscrewing direction (R) of said lid ( 18 ) from said spout ( 12 ) around said longitudinal axis (B).

16. A lid according to claim 15 , wherein said knurling ( 63 ) comprises a plurality of ribs ( 64 ) projecting from said side wall ( 28 ), said ribs ( 64 ) being inclined with respect to said longitudinal axis (B) and having a length ( 1 ) that increases in said unscrewing direction (R).

17. A lid according to claim 15 , wherein said knurling ( 63 ) comprises a plurality of ribs ( 64 ) projecting from said side wall ( 28 ), said ribs ( 64 ) being substantially parallel to said longitudinal axis (B) and having a length ( 1 ) that increases in the unscrewing direction (R).
