Abstract: A mould for production of glass bottles includes a body provided with an internal cavity first portion shaped according to the shape of the body of the glass bottle to be made. The bottom of the mould includes a first seat which is open both at the top, in communication with the internal cavity portion, and at the bottom. The mould further includes an adapter, which is also open at the top and bottom, which can be inserted in the first seat and provided at the bottom with a further shaped seat, which is intended for receiving a neck ring with relative finish thimble and plunger.

Abstract: A container includes an external receptacle including glass and has a bottom and a side wall to define an inner cavity. An internal receptacle includes glass, is housed within the inner cavity of the external receptacle, and has a bottom and a side wall. An intermediate element, including plastic or elastomeric material, is interposed between the internal receptacle and the external receptacle. The side wall of the internal receptacle includes a ring having a free upper face and a lower contact surface. The intermediate element is interposed between the lower contact surface of the ring and a support surface on a collar at the upper end of the side wall of the external receptacle. The collar has a step-like seat open upwards and toward the inner cavity of the external receptacle and extending between an upper free face of an upper edge of the collar and the support surface.

Abstract: A container for containing cosmetic products comprises an external glass receptacle (100), an internal glass receptacle (200), designed to be housed within the inner cavity (110) of said external receptacle (100) and in turn provided with its own inner cavity (210) for containing the product, and an intermediate element (300) made up of plastic material, destined to be interposed between respective mutual contact portions of the internal receptacle (200) and of the external receptacle (100). The side wall (212) of the internal receptacle (200) is provided, at its upper end, with a ring (213) having a free upper face (214) and a lower contact surface (215), and the intermediate element (300) is interposed between said lower contact surface (215) of the ring (213) of the internal receptacle (200) and a support surface on a collar (113) provided at the upper end of the side wall (112) of the external receptacle (100).

Abstract: The present invention concerns a method for producing a glass container comprising the steps of: a. melting a solid vitrifiable mixture to obtain a melted vitrifiable mixture; b. feeding the melted vitrifiable mixture to a plurality of glass container forming machines through respective feeding channels; c. combining at least one recycled glass frit in the melted vitrifiable mixture in at least one of the feeding channels, the frit being obtained from a vitrifiable mixture comprising recycled glass cullet and at least one fluxing agent; d. forming a glass container in said forming machines using the melted vitrifiable mixture coming from step c.

Abstract: A neck ring holder device intended to be used at a mould for forming glass containers (30), wherein the neck ring (41) for realizing the mouth (32) of the container can be opened and consists of a plurality of circumferential sectors (44) that can be moved apart from a closed position of the neck ring (41), in which the circumferential sectors (44) are coplanar and form a substantially continuous annular element, up to an open position of the neck ring (41), in which the circumferential sectors (44) are rotated out of said coplanar configuration, moving away from each other, about axes directed perpendicular to the direction of the axis (45) of said annular element, is characterised in that the movement of the circumferential sectors (44) from the closed position to the open position.

Abstract: The present invention relates to a process for the manufacture of a glass container that comprises the steps of: a) providing a first glass element; b) providing a second element made of a material selected from: glass, ceramic, metal and metallic alloy; said first element and said second element, joined together, defining a containment cavity of said glass container; c) depositing a sealing composition comprising at least one glass frit dispersed in at least one dispersing liquid on at least one surface of at least one of said first element and said second element; d) positioning said first element and said second element in contact with each other so that said sealing composition is arranged between said first element and said second element; e) heating said sealing composition so as to melt said glass frit and form a sealing layer between said first element and said second element. The present invention further relates to a glass container, such as, for example, a bottle, a cup or a jar, and related uses.

Abstract: A container provided with a sealing lid comprises a jar (11), a lid (12) for closing the jar, a rubber sealing ring (13), adapted to be interposed between an upper edge (17) of the jar (11) and a lower flange (18) of the lid (12), and a wire-shaped hooking element (14) of the lid (12) to the jar (11) for closing the container. The jar (11) is provided, in the proximity of its upper edge (17), with a collar (21) radially projecting from the jar side surface (22) so as to define below a circumferential step-like seat (23). The wire-shaped hooking element (14) is shaped with a pair of pivoting ends (20) rotatably received inside respective holes (19) in the lid (12) and with at least one curvilinear locking portion (24), in an intermediate position with respect to said pivoting ends (20).

Abstract: The present invention regards a method for internally coating a hollow glass body comprising the steps of: (a) applying on at least one internal surface of said hollow body at least one coating composition in form of liquid dispersion comprising at least one glass frit and at least one polymeric dispersing agent; (b) subjecting said internal surface comprising said coating composition to a thermal treatment, so as to obtain a vitrified coating layer.
