A plastic cap for a container neck formed with upper and lower external locking beads has a top disk from which depends an upper outer skirt having an upper internal locking bead and a larger diameter lower skirt having a lower internal locking bead. Between the skirt sections is an outward extending flange which is weakened by a notch cut in its outer corner to form a circumferential line of weakness. When the cap is seated on the neck the upper and lower beads inter-engage, the cap cannot be r...

To prevent tampering with the contents of containers for pharmaceuticals and other products, a plastic cap which is an improvement upon U.S. Pat. Nos. 3,338,446 and 4,166,552. The neck of the container is sealed with a commercially available foil seal; the cap is dimensioned so that the foil seal is inserted inside the cap prior to its being applied to the container. The dimensions of the cap accommodate the foil seal yet the snap-on and the tamper-proof features of the cap are maintained. At in...

A neck finish for plastic containers which are closed by plastic caps of the general type having an integral, thin, flexible inward-directed top flange at the lip which initially slants upwardly-inwardly at an angle of about 20.degree.. When the cap is applied, this top flange fits under the top disc of the cap and is depressed to an angle of about 10.degree.. It nests between the outer skirt and the inner skirt. The neck seals against the outer skirt in several locations (as in prior constructi...

The neck of a plastic container of the type originally intended for use with a foil type closure is formed with a top bead, a first reduced-diameter step and a second reduced-diameter portion and then a downward-outward widening breast. The cap has a top disk which seats on the neck and has an outer skirt having an internal upper bead engaging under the top bead and a second internal bead fitting deeply into the second reduced-diameter portion. An inner skirt depends from the disk and fits insid...

A plastics container and closure assembly in which the closure has a cap part, a tear away band, an anchor band, a hinge connecting the cap part to the anchor band and a bung to seat within the mouth of the container. The bung is deeper on one side than on the other whereby when viewed from one side the bottom of the bung is formed by an oblique line extending upwardly from the deepest part of the bung to the shallowest part and wherein the shallowest part of the bung is adjacent to a thumb tab ...

The present invention is directed to a method of controlling dimensional relations between an original pattern present in a mold and a recorded pattern formed in a layer of a substrate. In this manner, the size of the recorded pattern may appear to be magnified and/or reduced, when compared to the original pattern. To that end, the method comprises defining a region on the layer in which to produce the recorded pattern. The substrate is bent to produce a contoured surface in the region. Dimensio...

A plastic closure for containers comprising a top provided with depending inner and outer skirts, said skirts having facing surfaces which non-sealingly contact surfaces of a bottle neck adjacent its edge, said inner skirt merging into an annular radially projecting sealing member surrounding and integral with a concavo-convex closure web, said sealing member engaging a restricted area of the inner surface of the bottle neck. The closure may be removed by use of a cap lifter or the top of the cl...

A snap-on bottle cap seal device is made of a elastic material, such as a plastic, and is formed of a reusable sealing cap and a ring-shaped safety strip detachably secured to and extending circumferentially about the lower end of the cap when it is initially secured on a bottle. A lifting lug is formed on the lower edge of the sealing cap and a tear-off tab, attached to the safety strip, is secured by small web sections to the lug.

A snap-on bottle cap seal device is made of an elastic material, such as a plastic, and is formed of a reusable sealing cap and a ring-shaped safety strip detachably secured to and extending circumferentially about the lower end of the cap when it is initially secured on a bottle. The centrally disposed portion of the top surface of the sealing cap is concave and a tubular projection extends downwardly from the under side of the centrally disposed portion for engagement within the mouth of the b...
