Abstract: Some embodiments relate to a cartridge for use with an inhaler, the cartridge comprising: a plurality of source material units and a unit coupler configured for selectively interlocking to each of the source material units so that when the cartridge is operably attached to the inhaler, manipulation of the unit coupler moves the interlocked source material unit away from or back into the cartridge; the unit coupler and each of the source material units being formed with an interlocking geometry in which a protrusion of one fits within a respective recess of the other.

Abstract: According to some embodiments there is provided a replaceable flow tract for use with an inhaler device which delivers at least one substance to a user, the inhaler device comprising a housing shaped to receive the flow tract and to further receive a construct comprising source material from which the at least one substance is released; the replaceable flow tract comprising: a conduit comprising: a first opening; a second opening configured for being in fluid communication with a mouthpiece; and a third opening having an elastic sealing member extending therefrom, the elastic sealing member shaped and sized for pressing against the construct when the construct is within the housing.

Abstract: The present invention relates to aqueous adhesive dispersions based on (meth)acrylate which contain as the stabilizer a partially or completely hydrolyzed copolymer of at least one vinyl ester monomer, preferably vinyl acetate, and at least one alkene diester monomer, preferably, 3,4-diacetoxy-1-butene, and to the use of said compositions as labeling adhesives or sealing adhesives.

Abstract: A Waterborne adhesive comprising 1 to 50 weight-% of a (meth)acrylate copolymer manufactured by polymerization of at least one ester of methacrylic acid, acrylic acid, crotonic acid and/or itaconic acid with aliphatic alcohols, substituted aliphatic alcohols, aromatic alcohols, polyether glycols, and other copolymerizable monomers, having an acid number from 0 to 150 mgKOH/g, 0 to 40 wt-% of natural polymers 0.5 to 30 wt-% of urea, 0.1 to 20 wt-% of additives, characterized in that the adhesive contains 0.05 to 20 weight-% of a super absorbent polymer.

Abstract: A filled gum adhesive useful for producing remoistenable layers contains fillers, protective colloids, and a (co)polymer, wherein the (co)polymer is prepared by polymerizing one or more ethylenically unsaturated monomers in the presence of a dispersion of protective colloid and filler particles.
