Abstract: A one piece plastic closure for sealing a container, the closure having a top portion and a skirt portion depending from the top portion. The closure has an annular sealing rib which projects downwardly from the underside of the top portion. The rib includes a first portion having a substantially cylindrical inner surface contiguous with the underside of the top portion and disposed radially inward of the skirt and a second, frusto-conical, portion contiguous with the end of the first portion distal to the underside of the top portion and extending radially inwardly and terminating in a circular free edge, such that during engagement of the cap with the neck of the container, the second, frusto-conical, portion will be engaged by the free end of the neck and folded back against the first portion of the rib to form a gas-tight seal between the neck of the container and the closure.

Abstract: The invention is a hunter's personal safety game pack and method of making it. The game pack is especially designed for the wild turkey, with a bloodproof bottom pouch, a No-See-Um mesh drawstring bag top, and a shoulder harness. The wild turkey is a large bulky bird, weighing approximately 10 kilograms. It is cumbersome and messy, a burden to carry without a game pack. Carrying a wild turkey using one hand in the traditional over-shoulder position puts the hunter in a very dangerous situation. Carrying his gun with one hand is not recommended for safe gun handling; the exposed turkey on his back invites other hunters to shoot at the turkey and possibly shoot the otherwise successful turkey hunter in the back or head. Perhaps even more important, Lyme ticks may be transferred from turkey to hunter, with risk of the disabling and sometimes fatal Lyme disease. The taken turkey must cool quickly to avoid spoilage. The No-See-Um mesh top permits cooling ventilation without permitting any ticks to pass.

Abstract: The invention relates to a tamper-evident closure cap for a container having a neck and an opening defined in the neck. The closure cap of the invention includes an annular skirt member adapted to be secured to the neck of the container to prevent removal of the closure cap from the container, and a closure member hingedly connected to the skirt member for pivotal movement between a closed position whereat the closure member closes the opening of the container and an open position whereat the closure member permits access to the opening. A manually graspable tab is fixedly connected to the closure member for moving same from the closed position to the open position. The closure cap further includes a tamper-indicating member removably connected to the skirt member in overlying relation with respect to the tab and adapted to prohibit initial opening of the closure member prior to removal of the tamper indicating member.

Abstract: A wide-mouth, plastic container and lid. A leak-resistant seal is disclosed that withstands the stresses and strains imposed due to rough handling. An easily removable, tamper-evident lid is disclosed.

Abstract: A pressure relief venting lid for sealing an opening and providing pressure regulation of a container. The lid has a support plate attached by four angularly spaced spring assemblies to a port cover for sealing a filler opening in a manway cover for the container. The support plate overlies the port cover for fixedly supporting the spring assemblies and cover while protecting the springs and cover from impact or shock. The spring assemblies are disposed between the support plate and port cover for sealing the cover against the opening and allowing the cover to unseat from the opening to regulate the pressure within the container. The spring assemblies are offset equal distances from the center of the port cover to minimize bending moments that the cover may be subjected to. The generally circular port cover has a convex dished portion for strengthening the port cover to maintain the seal with the opening while under load.

Abstract: A polyethylene cap, for use with containers, particularly polypropylene containers for containing medical specimens in preservative fluid such as formaldehyde, is provided with a 3-face seal, wherein a rim portion of the container is trapped in sealing, contacting relation on three mutually adjoining faces, whereby any tendency of the container rim to "relax" out of sealing engagement with a contacting face portion of the cap is effectively precluded by the fit and the geometry of the cap seal. In the case of polypropylene, which is susceptible to such "relaxation", the subject cap enables the effective sealing of polypropylene containers so that advantage may be taken of the superior properties of polypropylene in non-reactive, secure containment of possibly contaminated medical specimens in liquids such as formaldehyde, a known carcinogen.

Abstract: A tamper indicating closure comprising a one-piece molded plastic closure which threads onto the finish of a container such that when the closure is removed from the container, a tamper indicating band becomes separated from a lower end of a cap member of the closure. The tamper indicating band is joined to the closure along a weakened frangible line. The band includes a flexible Y-shaped annular flap segmented into tabs and attached to the lower end of the annular tamper band. When the closure is applied to the container, the annular band folds radially inward and up toward the cap member. The interior surface of the band and the first leg of the annular band include corresponding ratchet teeth which are designed to accommodate a varying degree of finish tolerances and which engage upon removal of the cap from the container. A second leg of the annular flap extends outwardly beneath a peripheral bead on the finish of the container when the closure is fully attached.

Abstract: A disc made of thermoplastic material is inserted into the neck of a corked bottle and placed upon the top of the cork so that when the disc is partially melted, it forms a water resistant seal with the interior surface of the bottle neck and the cork. In forming the seal, the entire disc remains inside the bottle neck leaving the exterior of the bottle free from messy or harmful residue. The interior surface of the bottle neck may be straight or beveled at an obtuse angle. If the interior surface of the bottle neck is beveled, a disc with a frusto conical configuration is used in the method. A cover layer can be adhered to the top of the wax disc for ornamentation and labeling purposes.

Abstract: The screw-thread neck of a container, e.g. a glass bottle, has a closure with a tamper-evident ring connected to the lower end of the skirt of the closure by frangible bridges. Opposite the ring, the neck finish of the container has a nose-shaped projection the upper and lower flanks of which meet in a sharp edge, and has an annular groove below the projection. The bridges are formed in an inwardly facing groove above the projection and are radially spaced from the outer surface of the neck finish. The tamper-evident ring is swaged into close contact with the projection, is deformed into a channel on the neck finish below projection, and is closely engaged with the surface of the neck finish below the channel. Interference involving outward prying movement by a lever on the lower edge portion of the ring to disengage the ring from groove causes a pivoting action about the tip of projection leading to fracture of the bridges.

Abstract: The lid seal for wide-mouthed barrels (2) blow-molded of a synthetic resin utilizes a solid sealing ring (9) of plastic, this ring being in contact with the underside of a solid flange (10) projecting radially outwardly at a spacing below the barrel opening from the barrel wall, as well as a counter ring (11), likewise produced of plastic, this counter ring resting on a flange (12) molded on the bottom to the outer lid rim (4). Locking sleeves (13, 14) are formed on the clamping rings (9, 11), distributed about the circumference, these sleeves engaging in corresponding bores (15, 16) in the barrel flange (10) and in the lid flange (12). The clamping rings (9, 11) and the locking sleeves (13, 14) molded thereon have conical aligned through bores (17, 18). For closing the lid (1) placed on the wide-mouthed barrel (2), clamping bolts (19) of plastic or metal are pressed, by a pressing tool, from above into the conical bores (18, 17) of the two clamping rings (11, 9).

Abstract: The main theme in the design of this invention is to provide adequate protection while allowing for easy installation and removal without interrupting the operation of the device which is being protected. The two most important components of this invention are the use of resilient clips on the side walls with each clip having a leg extending inwardly allowing this leg to be inserted between the device and the surface, the second important component is the use of gasket material between the frame and the device to be protected. This combination allows for protection from the elements and from accidental operation even without either open end being covered.
