Abstract: A safety closure secured against accidental opening or opening by small children comprises a lid and a cap interconnected by a hinge made of a single piece and having a single wall, the lid having a lateral skirt, a top surface with a pouring opening and an outer lateral grip that delimits a slot for engagement with the lock provided in the cap. The continuous lateral skirt has an internal thread, and a flap or ring is provided at the lower edge of the skirt for attaching the lid to the neck of a container. The inwardly extending flap secures the lid against axial movement when the lid is rotated in order to unscrew it. The cap has a sealing plug that closes the pouring opening and an external flap from which a locking body protrudes, the locking body having a central cutout that forms a spring blade that extends outwards from the locking body.

Abstract: The invention pertains to the field of caps and toys designed as building blocks, and relates in particular to a functional cap that can be re-used as a playing toy designed as interlocking or stackable blocks after the cap has been used for sealing packaging containers. The cap comprises a body (1) with a top surface (2) provided with projections (3) that can take the shape of rings, pins or any other shapes that fit into recesses or cavities (41) provided in the lower region of the body (1) or in structures provided in the sidewalls (5) thereof.

Abstract: A safety closure secured against accidental opening or opening by small children comprises a lid (1) and a cap (2) interconnected by a hinge (3), preferably made of a single piece and having a single wall, the lid (1) having a lateral skirt (11), a top surface (12) with a pouring opening (13) and an outer lateral grip (7) that delimits a slot (8) for engagement with the lock provided in the cap (2). The continuous lateral skirt (11) has an internal thread (9), and a flap (10) or ring is provided at the lower edge of the skirt for attaching the lid to the neck of a container. The inwardly extending flap (1) secures the lid (1) against axial movement when the lid is rotated in order to unscrew it. The cap (2) has a sealing plug (14) that closes the pouring opening (13) and an external flap (4) from which a locking body (5) protrudes, the locking body (5) having a central cutout that forms a spring blade (6) that extends outwards from the locking body (5).
