Abstract: A re-closable vent for a container closure which requires no pre-formed holes in the closure deck, provides a tamper-evident feature, and provides simple rotation of a cap structure to open and a vent after punching out a frangible deck section.

Abstract: A container package includes a container and a lock-on closure that couples to the container. The container includes an annular sidewall. The closure includes a channel portion having an inner, an outer, and a top wall that define a channel. The inner wall includes a primary seal having sealing ridges formed thereon. The closure further includes a single, flexible sealing wiper appendage extending away from the top wall. When the sidewall of the container is outside of the channel, the appendage is in a first position in which it extends downwardly and is angled inwardly so a terminal end of the appendage is freely suspended within the channel. When the sidewall of the container is in the channel, the appendage is in a second position in which the terminal end is closer to the inner wall than in the first position and the appendage contacts the top rim.

Abstract: A molded plastic closure is configured to provide a plug fit with the top rim of an open top container having an outwardly protruding rim flange. A two-part seal preventing leakage of fluid from the container is provided by means of a ridge structure on the inner wall of the inverted U-shaped channel of the closure peripheral structure as well as a flexible sealing wiper appendage which is formed integrally with the top of the inverted U-shaped structure and which deformingly contacts the top surface of the container rim when the rim is essentially fully inserted into the U-shaped channel. The wiper appendage is formed to angle toward the inner channel wall in the undeflected condition.

Abstract: The combination of molded plastic closure for an open top container and an extensible plastic spout adapted to be joined to the deck of the closure in either of two ways. In one way, the spout is molded with a U-shaped peripheral channel which receives a downwardly extending flange surrounding an aperture in the deck. In another way, the spout is pre-molded and then used as an insert when molding the closure.

Abstract: A manually extendible plastic spout for use in combination with the closure for an industrial container. The spout has a peripheral flange with a U-shaped channel which receives a downwardly extending flange on the closure so that the spout is installed from the bottom side of the closure rather than according to the more customary top-mounted procedure. The body of the spout is pleated and has an outlet collar which is threaded to receive a cap having a pull-ring, an integral internal seal is also provided. The spout can be extended to any of several stable positions or conditions.

Abstract: A molded plastic container having an open top and an outwardly smooth sidewall wherein the interior surface of the sidewall is characterized by a plurality of parallel vertical flutes defined by shallow, smooth concavities joined by flat columns of uniform thickness wherein the ratio of the circumferential diameter of each concavity to the circumferential width of a column is about 8:1. The outside surface of the container is smooth and molded with two integral, vertically spaced, circumferential rings for added hoop strength. The container exhibits a high stacking strength-to-weight ratio. The preferred material is HDPE.

Abstract: Two embodiments of a molded plastic container/closure combination are described. Each can be structured to provide a child resistant opening feature and, optionally, a tamper-evident feature. In both embodiments, the closure has radially extending bayonets arranged around an outer skirt, which bayonets can be rotated into a position underlying semi-annular ribs in a beam molded integrally with the sidewall of the container. Rotation of the closure in the unlocking direction is opposed by a structure which requires depression of a release tab downwardly. In one embodiment, depression of the release tab requires that a frangible element first be fractured and removed from the container sidewall. In the second embodiment, depressing the release tab is made possible by a living hinge formed on one side of the release tab.

Abstract: An all-plastic container comprising the combination of injection molded pail and lid. The lid initially locks onto the container at upper and lower undercuts and seals thereto by virtue of an inverted U-shaped peripheral section. A tear groove is formed in the lid skirt between the upper and lower locks to facilitate removal of the lower lock. The upper lock is segmented so as to make removal of the lid easier once the lower lock is removed. Indicia on the lid shows where the gaps in the lock segments are located. The lower lock may also be segmented to provide drainage for overfill which comes out of the pail when the lid is first applied. The lid and pail are dimensioned to provide a wedge seal between an unflanged pail rim and the top lock and to maintain a strong connection and seal even after the lower lock is removed.

Abstract: A tamper evident, pull-out flexible spout for use in combination with a container lid wherein a cap can only be removed from the threaded end of the spout by lifting a pair of bail rings which are attached to the cap by way of a set of frangible connectors and thereafter pulling the spout out from the stored position at least part way toward the use position thereby to disengage lugs on an exterior surface of the cap from a pair of one-way stops on an interior surface of the spout ring.

Abstract: An all plastic paint container assembly comprising a container, a ring assembly attached to the rim of the container and a pry-off plastic closure having a dual sealing arrangement with the ring member and an undercut lock at a location which provides maximum circumferential area. Containers of this design can be stacked both with and without the ring members attached. Three embodiments are disclosed, providing double and triple closure locks and multiple seals.

Abstract: A one-piece thermoformed food package comprises a rectangular deep drawn base with a peripheral female rim channel and, connected to the base by a hinge, a lid having a peripheral male rim feature. In the corner of the base is a breakaway release feature which underlies a corner tab of the lid which is tucked into an inside edge of the female rim so that it cannot be accessed to open the package. When the user pushes up on the breakaway release feature, one or more frangible sections are broken and the lid corner tab is raised enough to open the package.

Abstract: A thermal protection sleeve for use in combination with hot drink cups comprising a flat embossed sleeve or band of compressed paper embossed with straight-sided geometric figures over much of the surface thereof. However, overlapping end surface areas are not embossed but are glued together with a suitable biodegradable adhesive. In addition, an unembossed logo blank is provided substantially in the center of the band.

Abstract: A drink-through plastic lid is injection molded in one piece to define a rim structure which snaps onto the rim of a cup and an asymmetric crown having a drink-through opening formed at the high point of an outer deck. An integral hinged flap with a C-shaped seal lip on the inside surface can lock by means of said lip into the drink-through opening when in one condition. The flexible outer edges of the flap latch into a lock-back recess which interrupts an intermediate inner deck formed between the outer crown deck and the floor of a well in the interior area of the lid.
