Abstract:
Process for manufacturing a metal can with a threaded neck on which a removable head can be fitted, includes the steps of forming a can with a closed bottom end, a cylindrical wall and an open top end, forming a neck at the open top end, obtaining a ring with a spindle hole of known diameter and a threaded external surface, sleeve fitting the ring by driving the spindle hole over the neck, and plastically expanding the neck by an amount sufficient that its outer diameter exceeds the diameter of the spindle hole when unstressed.
Abstract:
The invention relates to a process for manufacture of a top 1 intended to be attached on a container or a flexible tube 50 and comprising a neck 3 the opening 7 of which is connected by a tearable ring-shaped part 10 to a cover 20 serving as an impervious stopper prior to breaking of the ring-shaped part and then being able to serve for recapping. The cover 20 is extended by a plate 30 the periphery 31 of which has a common axis of symmetry with the tearable ring-shaped part 10 and is provided with at least three lugs 32. The skirt 40 is open at one end; its inner surface 46 is partially cylindrical, its section following the exact shape of the periphery 31, except for the lugs, of the plate 30, and is provided with at least three cavities 41 intended to accommodate said lugs. The skirt is drawn around the plate 30 to the point of immobilization, brought about by the insertion of the lugs 32 on the plate 30 into the cavities 41 of the skirt 40.
Abstract:
The cap (1) portion of the assembly comprises at least one guarantee strip (2, 3) connected to its body (5) by breakage bridges (4), the neck of the receptacle carrying ratchet teeth and the guarantee strip (2, 3) carrying internal teeth (6) adapted to cooperate with the ratchet teeth. The ratchet teeth (9) are elastically inclinable in the direction of screwing to allow the cap (1) to be screwed on while preventing its being unscrewed without breaking the bridges (4). At least one guarantee strip (2) has free ends (21) and is ejected transversely the first time the cap (1) is screwed on. The internal teeth (6) are so disposed that they cooperate with the ratchet teeth by only a single internal tooth (6) upon screwing and unscrewing. The cap (1) can be applied to tamper-proof receptacles in the cosmetic, pharmaceutical, hygiene, food and cleaning product industries.
Abstract:
A process for producing markings or lines engraved on a sheet or a tubular piece (6) made of plastic material or multi-layered metal-plastic material less than 1 mm in thickness, in which the sheet or piece (6) is gripped between a tool (1) bearing one or more marking contour(s) (2, 3) and a resilient support (9), in order to produce the engraved markings or lines. The sheet or piece (6) is at less than 50.degree. C. during the gripping stage, and in the resilient support (9) has a Shore hardness D of between 70 and 120, the markings or lines obtained being produced by plastic deformation with elastic return.
Abstract:
The assembly of a closure (3) and a receptacle (1) having a neck (2) of plastic material surmounted by a tamperproof cover 98). The closure (3) comprises an opening capsule (3) provided with a base (4), and the base (4) and the neck (2) are configured for snap-on engagement after the commencement of insertion in full cross-section of a fitting device (25) onto the cover (8), and, lower down, a screwing device, these devices (15 and 25) allowing the cover (8) to be ruptured and to be fitted into the neck (2).
Abstract:
A dispenser having a head fixed on a body or a skirt, and a cap, with the cap comprising an outer skirt, a deformable internal crown and an intermediate ring, the head and the intermediate ring of the cap having complementary screw threads for raising and lowering the cap, the head including a stopper supported by sloping legs fixed inside the head and occluding an aperture of the cap when the cap is in a low position, the internal crown and the head cooperating sealingly once the cap is engaged on the head, the head including a shoulder which has at least one stop lug cooperating with a rib on the intermediate ring near its lower end to hinder an uncontrolled unscrewing of the cap when the cap is screwed downwards to close the dispenser.
Abstract:
A pasty product dispenser (1) comprising a body defining a chamber for storing at least one main pasty product and pumping system defined by a wall surmounting the storage chamber and by an intake valve member, the wall carrying on the side of the storage chamber a separator tube enclosing the valve member and comprising passages for at least one secondary pasty product contained between the separator tube and the body, the passages being outside the separator tube, the wall having a rotating cover with traversing apertures, rotation of the cover progressively masks or exposes the passages, the apertures being occluded by the valve member when it is in its low position.
Abstract:
A bag-type dispenser comprising a casing including a tubular body and a separate body portion, a tubular skirt, a dispensing portion and a one-piece molded annular dome of plastic material including an upper annular portion fixed to the dispensing portion, a lower tubular portion directly and sealingly fixed to the tubular skirt at an upper portion of the skirt over a height of 5 to 20 mm, and a lower annular portion outside the lower tubular portion, directly and sealingly fixed to the tubular body at an upper end. The dispenser can be filled with product by way of a lower end of the tubular skirt which is open, and which can subsequently be closed to form a bag.
Abstract:
A container and its threaded sealing cap with a tear-off security strip, a constricted portion of the container being threaded and provided with flexible teeth having an increasing spring action ratcheting with notches of the security strip, and having a mechanical strength making it possible to guarantee that the container is tamper-proof, while insuring ease of opening after tearing off the security strip.
Abstract:
The invention concerns a tube for the distribution of a paste with stripes in which the head 1 which is connected by moulding to the skirt 4 of the tube has an inner skirt 8 which is in one piece with said head 1, which skirt 8 having flow openings 13, 14 for the stripe product, which skirt 8 has pairs of inner longitudinal ribs 17, 18, 22 for guiding the stripe product, disposed on respective sides of said openings 13, 14 and extending towards the top of the neck portion 7. The head of the tube is of a double skirt configuration, its outer skirt 16 forming the outside of the neck portion 7 and its inner skirt 8 extending from the top 5 of the head 1 and forming the inside of the neck portion 7 and the discharge duct 8 for the pasty product. Flow openings 13, 14, 15 are disposed in part at least above the notional extension of the slightly inclined rear surface 10 of the shoulder 2. The inner skirt 8 carries inner longitudinal ribs 26, 35 for retarding the flow of the main pasty product, and the ribs comprise ribs 26 extending from each flow opening 14 to at least the lower third of the portion of the skirt 8 which is disposed below the opening 14.
