An apparatus and system for dispensing a food and beverage product where a flowable product is extracted from a flexible pouch, and where a nozzle region exists through which the flowable product evacuates the flexible pouch. The nozzle region has a lock seal that locks the flowable product within the flexible pouch when a pressure less than a first threshold value is applied to the flexible pouch. There is also a frangible seal located above the nozzle region that is configured to lock the flowable product within the flexible pouch when pressure less than a second threshold value is applied to the flexible pouch and when the first threshold value is larger than the second threshold value.

Flexible enclosure includes a front wall and a back wall that oppose each other and a side wall that joins the front and back walls. The front wall, the back wall, and the side wall are discrete sections. The front wall and the back wall are attached to opposite edges of the side wall. The side wall is configured to have a slit between top and bottom wall portions of the side wall. The flexible enclosure also includes a resealer extending between the front and back walls along the bottom wall portion of the side wall. The bottom wall portion is separable from the top wall portion along the slit. The bottom wall portion is configured to flex outwardly and away from the top wall portion and form a spout of the flexible enclosure. The resealer is configured to close the spout.

A discharge member used for discharging contents accommodated in a container includes: an attachment part to be attached to the container; and a tubular part that is formed into a tubular shape, through which the contents from the container pass, the tubular part being provided with a tubular member in which a functional resin layer is disposed as an intermediate layer inside in a radial direction. The functional resin layer provided to the tubular member is disposed closer to the outer circumferential surface among the outer circumferential surface and the inner circumferential surface of the tubular member.
