A device that includes a first portion including a first polymer, a second portion including a second polymer, and a third portion defining a third polymer. The second polymer is substantially not bondable to the first polymer, and the third polymer is bondable to the first polymer and fixedly secures the first portion to the second portion. A device that includes a body and a closure and including and a first polymer, a second polymer and a third polymer, wherein the first polymer is bondable with the second polymer, and the third polymer is substantially not bondable to the first polymer.

A device comprising a body including a first polymer and a closure including a second polymer that is substantially not bondable to the first polymer and has a relatively higher shrinkage rate than the first polymer, wherein at least a portion of the closure overlaps at least a portion of the body, forming a hermetic seal therebetween and defining a sealed, empty, sterile container.

A cartridge system for delivering an aqueous solution made with a mixture of an active material and a liquid medium, where the cartridge system includes a bottle-shaped container and a pump fastened to a neck of the container, where the container is filled with the liquid medium. The container includes a cartridge and an intake tube of the pump sealingly inserted in an upper side of the cartridge, where the active material is supplied to the cartridge through the intake tube. The cartridge is sealed from an exterior by a piston or a stopper, where the piston or stopper is movably arranged in a wall of the cartridge and configured to enter into an interior of the cartridge under reduced pressure produced by the pump and opens to the exterior of the cartridge so that the active material is mixable with the liquid medium.
