Cationic or zwitterionic polymer adhesives, adhesive articles, aqueous polymerizable pre-adhesive reaction mixtures, and methods of preparation that include internal incorporation of a hydrocarbon tackifier. An aqueous polymerizable pre-adhesive reaction mixture includes one or more cationic (meth)acrylate monomers, one or more low Tg nonionic monomers having a (meth)acryloyl group, optionally one or more anionic (meth)acrylate monomers, and one or more hydrocarbon tackifiers.

Vent assemblies movable between a vented position and a non-vented position are described along with reservoirs in which the vent assemblies may be used. The vent assemblies each include an aperture and a closure member. The closure member is configured for movement along a cam surface to generate a compressive force such that a sealing surface on the closure member is forced against the wall of the reservoir and over the aperture such that the vent assembly is in the non-vented position. The closure member movement may be, e.g., rotational or linear (i.e., translational) when moving between the vented and unvented positions.

Container assemblies () that transition between a sealing state and a retained venting state are described. The container assemblies each include a body portion () having an open end (), and a lid portion () adapted to cover the open end of the body portion to create an enclosed volume, e.g. reservoir, and additionally comprise a venting feature (). When the fluid pressure within the enclosed volume is less than a threshold pressure, the lid portion is in a sealing state such that the lid portion and the body portion cooperate to maintain a substantially fluid-tight seal against fluid leaving the enclosed volume. When the fluid pressure is greater than or equal to the threshold pressure, the lid portion is in a retained venting state such that the excess fluid pressure from the enclosed volume vents through the venting feature while retaining the lid portion on the body portion.
