  • Patent number: 4129225
    Abstract: There is disclosed a composite container manufactured from a blown glass bottle for packaging product under pressure, such as beer or carbonated beverage. Combined with the glass bottle is a wrap or covering of an organic polymeric material or combination of materials, such as foamed polystyrene, foamed polyethylene, foam-film laminates, or film cured in place from a powder, overlying the exterior of the bottle. The covering or wrap is of variable strength along the axial extent of the bottle. The composite bottle has the thickest or the strongest section of wrap overlying the upper part of the bottle, including the neck and shoulder of the glass wall of the bottle such that the strongest section of the wrap encloses or surrounds that portion of the bottle in the vicinity of the "head space" in the filled package. The head space contains compressed gas released from carbonation in the product, and the gas is at substantial pressure.

  • Patent number: 4127209
    Abstract: A metal cap for crimping on the neck of a container has one or two tear lines of reduced strength about its skirt which define a tear-off strip. A perforation for initiating tearing extends across the width of the strip and at least one smaller perforation is also provided in the strip. A tear-off tab (plastic tape) engages both sides of the strip and is joined together through the perforations. The larger perforation is either U- or L-shaped, a straight slot or variations thereof. The portion of the tear line adjacent the larger perforation may be scored to facilitate initial rupture in the desired direction. One or more circumferential reinforcing ribs may be provided in the skirt on one or both sides of the tear-off strip. In addition to the full circumferential tear line, a partial tear line may extend between the larger perforation and a slot in the edge of the cap to provide an initially narrow tear-off strip, which enlarges to include the edge of the cap.

  • Patent number: 4126240
    Abstract: A unitary, integrally-formed, molded plastic closure used to seal containers having threaded necks and a radially extending collar situated therebelow. Closure includes internally threaded cap, plurality of tongues spaced about lower periphery of cap, frangible tamper indicating ring spaced axially below lower periphery of cap, and a plurality of thin webs interconnecting the ring and the tongue. Closure is advanced over the threaded neck on container by automated machinery so that ring abuts against collar on container. Indicating ring includes weakened area to allow limited radial expansion, and an inwardly extending radial flange may be defined at upper end of ring. Lugs are formed on periphery of tongues.After ring abuts against collar, continued advancement of the closure along threaded neck (1) shears the webs and frees the tongues from the ring; (2) subsequently enables the tongues to engage and enter the ring in serial fashion, and (3) resiliently interlocks the ring and the tongues.

  • Patent number: 4126239
    Abstract: A canister for an explosive primer containing capsensitive aqueous gel explosive is formed from a thermoplastic by blow-molding a pair of semi-cylindrical bottles connected by an integral hinge which have one or more corresponding grooves in their mating flat longitudinal surfaces. When the flat surfaces of the two containers are placed in contact and the containers are fastened together to form a cylinder, the matching grooves form a central longitudinal tubular passage through the canister and, if desired, one or more cylindrical wells in close proximity to the central passage.

  • Patent number: 4125201
    Abstract: A closure cap adapted to seal the neck of a container, the closure cap having a top portion and an annular skirt which extends from the periphery of the top portion, the skirt being provided internally with a skirt thread which is adapted to cooperate with an external neck thread on the neck of the container, the skirt also being provided internally with a radially extending resilient annular thread flange which is disposed immediately adjacent to and on the same helix as the skirt thread and is disposed on the side of the skirt thread facing the open end of the skirt, the thread flange, when undeformed, extending substantially radially inwardly of the skirt thread with a gap therebetween, the thread flange, when the closure cap is fully screwed onto the neck resiliently engaging the outer wall of the neck to effect centralization and resist loosening of the closure cap, the thread flange being forced by the neck towards the skirt thread so as to reduce said gap.

  • Patent number: 4121638
    Abstract: The present locking arrangement is attached to the inner side of a wheel cover for a spare wheel and tire assembly which is mounted on the outside of a vehicle. Slotted plates attached to the wheel cover receive the opposite ends of a bar, which extends diametrically across the inner side of the wheel cover. This bar is transversely bent at one end, at least, for retention in the slotted plate there. A padlock coacts with the bar and at least one of the slotted plates to retain the corresponding end of the bar in that plate.

  • Patent number: 4117946
    Abstract: A plastic cap has a closure wall positionable across a container neck opening, and an integrally formed skirt wall adapted to extend around the container neck. Projections are formed on the inner surface of the skirt wall and extend laterally of the skirt toward the neck. Elongated lug-like formations depend from the closure wall into the neck opening and bias portions of the container neck toward the skirt-carried projections to clamp neck portions against the projections, whereby the cap is securely releasably retained on the container neck. In preferred practice, the skirt-carried projections cooperate with neck-carried protrusions to provide snap-on, snap-off actions as the cap is pressed onto and removed from the container neck.
