FIELD: process engineering.
SUBSTANCE: invention relates to dispensers of fluids contained in deformable bag arranged in stiff container. At least part of bag extending radially from neck extends beyond container neck side surface nearby, at least, neck free edge. Pump case is compressed by ring cap to seal bag flange. At least one shaped element arranged behind bag flange free end extends from ring cap inner surface. Said shaped element retains the flange in dispenser operation. Flange surface faces the container to interact with flange surface and to extract the nag from container together with the pump when ring cap is detached and removed from container.
EFFECT: simplified detachment of glass container from plastic bag.
