A collapsible cup has a tubular body having an upper end and a lower end, centered on an axis, and formed with a plurality of helicoidal ridge formations spaced angularly around the tubular body and each extending between the ends of the body. A floor of greater rigidity than the body closes the lower end of the body. A ring reinforces the upper end of the body. The body and ridges are formed of an elastically deformable synthetic resin such opposite angular twisting of the upper and lower ends axially compresses together the upper and lower ends and moves upper end down close to the lower end.

Disclosed are embodiments of containers, caps, sealing assemblies, and associated components. In one embodiments, a sealing assembly can include an expander actuator operatively coupled to an expander, which expander is operatively coupled to a seal. In a locking state, the expander actuator is configured to cause the expander to expand horizontally against the seal. The expansion of the seal against a shoulder and/or a neck of a container provides a locking, leak-proof seal. In an opening state, the expander is configured to provide an upward movement of the expander actuator, allowing the expander to return to its unexpanded form, which in turn causes the seal to return to its unexpanded form. When the seal is in its unexpanded form, the sealing assembly (along with an associated cap) can be pulled away from the container body.

A cap includes a housing, a flexible membrane made from a resilient material and disposed over at least a portion of the housing, a first slider at least partially disposed in the housing and movable between a first position and a second position with respect to the housing, and a second slider at least partially disposed in the housing and cooperating with the first slider, when the first slider is in the first position the second slider is in a locked position in which a distal end of the second slider presses against and extends the flexible membrane outwardly from the housing, and when the first slider is in the second position the second slider is in an unlocked position in which the distal end of the second slider does not extend the flexible membrane outwardly from the housing as much as compared to the locked position.

Provided is a bandage composition dispenser and/or applicator that includes a nozzle and a cap. In some embodiments, the dispenser and/or applicator is used to dispense a bandage or dressing composition that forms a durable film bandage or skin protectant.

The present invention is based upon a coating system that uses polycyclic polyester polymers and phenolic resins. The coating system comprises first and second coatings. The first coating preferably is derived from ingredients comprising a polycyclic polyester resin having first and second fused rings that share at least two atoms in common. The second coating preferably is derived from ingredients comprising a polycyclic polyester resin that may be different than the polyester of the first coating.

A lubricating oil maintenance cap assembly includes a cap having an outer side, and an inner side, a shield, anchor assemblies, the shield is applied to the inner side of the cap, and the anchor assemblies anchor the shield to the cap. The cap is fashioned of a first material, the shield is fashioned of a second material, and the second material is different from the first material and is more thermally resistant than the first material enabling the shield to thermally shield the inner side of the cap.

A spout assembly includes a spout and a cap. The cap includes an inner ring having an outer peripheral surface provided with a first region with a first outer diameter and a second region with a second outer diameter. The spout includes a side wall having an inner peripheral surface provided with a first region having a first inner diameter and a second region having a second inner diameter. When the cap is threadably engaged with the spout, the first region of the inner ring is in close contact with the first region of the side wall of the spout throughout the circumference, and the second region of the inner ring is in close contact with the second region of the side wall of the spout throughout the circumference.

A filter baffle assembly, including a filter cap engageable to a mouth of a container, the filter cap including a filter vent operatively attached to a liner situated within an inner space of the filter cap, and a gas permeable baffle disposed between a mouth of the container and the filter vent, covering the filter vent, the baffle including a single perforation to permit gas exchange between an interior of the container and the filter vent, and to protect the filter vent from contact with contents housed in the interior of the container. A gas permeable point baffle for protecting a filter vent from contact with the contents of a container, including a single perforation, the point baffle being welded to a liner and covering a filter vent operatively attached to the liner, housed within a cap engageable to the mouth of the container. A method for protecting a filter vent from the contents of a container.

A drinking container is provided that can include a lid member and a cup member. The lid member can include a base member and a spout extending up from the base member. The spout can provide a fluid passageway from outside the drinking container to the volume of the cup member so that a child may drink liquid contained within the cup member. When the lid member is removably coupled to the cup member, two or more seals are created around the circumference of the drinking container between the lid member and the cup member to decrease the likelihood of leakage from between the cup member and the lid member when the lid is coupled to the cup member.
