Abstract: A tamper evident hinge type closure includes, as is conventional in such closures, a body portion, a lid portion and a hinge portion. Advantageously, at least one tamper evident band is provided so as to mechanically secure the lid portion to the body portion at a position that is distal from the hinge. The tamper evident band, which is designed to break upon initial opening of the closure by a consumer, is preferably integral with both the body portion and the lid portion, so as to ensure more reliably than was possible with interlocking mechanical tamper evident structures that the closure may not be opened without defeating the tamper evident band. A process for making the improved closures is also disclosed.

Abstract: A closure (2A) overlies a liner (6) which seals a container mount defined by a peripheral edge (12) of the container. The liner (6) includes a sealing flange (31) having an upstanding outermost terminal rim (40) of resilient material which is folded inwardly during closing movement of the closure shell (2A) toward the sealing flange (31) to form an unflattened fold constituting a biasing means for biasing the periphery of the sealing flange (31) against the peripheral edge (12) of the container mouth.

Abstract: An improved mascara brush has a typical twisted wire core containing bristles having a high durometer and relatively large diameter. The bristle density is in the range of 8 to 20 bristles per turn; more preferably 10-15 bristles per turn, and most preferably 12-14 bristles per turn. The bristles have a diameter of from 0.010 inch to about 0.016 inch, preferably 0.011 inch to 0.014 inch, and most preferably 0.011 or 0.012 inch. The bristle durometer is in the range of about 92 Shore D hardness to 120 Rockwell R; more preferably about 100 to 120 Rockwell R; most preferably about 103 to 108 Rockwell R. In one preferred embodiment, the filaments have a durometer of 108 Rockwell R. The brush is stable and effective for rapid lengthening of eyelashes and combing of the eyelashes.

Abstract: A beverage can cap member (16, 100) is configured so that its exterior surface (28) extending radially inwardly from the rim (18) or rim forming portion (140) is substantially flat or continuous, or has a slight curve from a position adjacent from the rim (18) or rim forming portion (140). The cap member (16, 100) may have a countersink (160) which is filled with a filler material including a curable adhesive, an insert (180) of a natural or synthetic material or the like. The filler material increases the structural strength of the cap member (16, 100) to an extent that it can be made of a relatively thinner material and still complies with the minimum peaking pressure of the industrial standard.

Abstract: A press-on, twist-off container assembly of the type that is used, for example, and baby food containers includes a container that has, as conventional, a finish portion with at least one external threadand a closure that is mounted on the container. The closure is of the press-on, twist-off type and includes a panel portion and a skirt portion that together define a generally cylindrical interior recess. As is conventional, a deformable gasket is mounted within the interior recess that has a thread engaging portion that is deformed so as to at least partially conform to the external threads of said finish portion of said container. The thread engaging portion advantageously has a plurality of inwardly extending raised flutes that are circumferentially spaced irregularly about the thread engaging portion. At least some of the flutes are in contact with at least one of the external threads at respective points of contact, and each external thread has a total distance spanned by such points of contact.

Abstract: A system for pressure molding plastic material includes a source of hot flowable plastic material and a manifold for receiving hot flowable plastic material from the source and for transporting the hot flowable plastic material to a nozzle that is disposed within a nozzle cavity. A heater is provided to heat the nozzle and is positioned outside of, but close to, the nozzle cavity and includes at least one electrical supply wire. A shut-off seal is positioned within the nozzle cavity to seal the nozzle with respect to the wall defining the shut-off cavity. In addition, a secondary seal is most advantageously positioned between the shut-off seal and the heater for ensuring that any hot flowable plastic material that might leak through the shut-off seal does not come into contact with the electrical supply wire. This has been found to increase the reliability and operating life of conventional pressure molding systems.

Abstract: A closure cap comprises in a transition range (7) between the cap base (2) and the cap skirt (3) a bulge (6) for pressing a sealing disk (5) against a container opening. The bulge (6) comprises an undercut (8) and in sections (9) is provided with weakenings (10) which give the bulge (6) a radial flexibility.

Abstract: A drive for use in the manufacture of cans comprises a hydraulically powered guide pod to which a can bodymaker is attached. The guide pod slides along a guide rod which is fixed in the bodymaker. Forward and rear hydraulic chambers are defined between the pod and the guide rod by means of bushings and a seal. Passage of fluid through ports to and from the chambers causes the pod and bodymaker to move forwards and backwards. The length of the stroke can be set by the distance between the ports. A rotary valve is used to control the timing of the drive and control flow of hydraulic fluid, which is typically obtained from the bodymaker coolant supply.

Abstract: A retortable all-plastic closure having a generally circular top portion and a generally cylindrical downwardly depending skirt. The top portion has upper and lower surfaces. The lower surface of the top portion forms a circumferentially extending ridge that projects downwardly. The ridge forms a first structural wall. A second structural wall is formed in the top portion adjacent the first wall. A flexible liner made from a thermoplastic elastomer is bonded to the lower surface. The portion of the liner covering the first structural wall forms a downwardly extending liner wall. The portion of the liner covering the second structural wall forms a top liner wall. The diameter of the downwardly extending liner wall is greater than the diameter of the top of the container neck inner wall to which the closure is applied so that the container neck compresses substantially the entirety of the downwardly projecting liner wall.

Abstract: A method of forming a can end comprises the step of forming a substantially circular metal blank having a periphery and a center panel. An annular recessed panel is subsequently formed in the blank. The recessed panel has a first depth in relation to a substantially annular portion of the blank contiguously formed with the recessed panel. The substantially annular portion of the blank is then coined while the recessed panel is re-formed to a second depth in relation to the substantially annular portion of the blank. The second depth is greater than the first depth. Forming the can end in this manner minimizes warpage of the can end, and thereby allows the can end to be formed from a relatively thin sheet of metal.

Abstract: A sequentially moulded closure arrangement (1) comprising a body (4), which forms the shoulder of a container, such as a tube (2), and defines a dispensing passageway, a cover (5), to seal the dispensing passageway, and a fixing ring (7) to join the body to the container. The cover is connected to the body or the fixing ring by a moulded hinge (6) and the cover and fixing ring are sequentially moulded together as an integral moulding, removing the requirement to assemble the cover, body and fixing ring in a separate assembly operation. The arrangement has further advantages relating to cleanliness and ease of dispensing.
