A resealable bag includes a first end, a second end, a first transverse seal sealing the first end and a second transverse seal sealing the second end. The second transverse seal is part of a weak seal zone of the bag that can be readily unsealed by a consumer by hand. The bag further includes a third transverse seal between the first transverse seal and the second transverse seal, closer to the second transverse seal than the first transverse seal. The third transverse seal is at least partially longitudinally aligned with the second transverse seal and can be selectively unsealed and resealed by the consumer by hand. In one embodiment, a fourth transverse seal is located between the first transverse seal and the second transverse seal, while being at least partially transversely aligned with the third transverse seal, and part of a strong seal zone of the bag.

Systems and methods of a container having a tack welded fin seal are disclosed. The container may include a film, a tack weld joining a first outer portion of a first edge and a second outer portion of the first edge, and a fin seal joining a first inner portion of the first edge of the film and a second inner portion of a second edge of the film. The container may include a faceplate integrally molded to an outer layer of a first end portion of the film. The faceplate may include substantially the same composition as an outer layer of the first end portion, such that no distinct layers are formed between the faceplate and the film. The tack weld may be formed at a tack welding system, and the fin seal may be formed at a fin sealing system having a mandrel.

The invention relates to a nozzle for inflating a spout film bag, the lateral surface of which nozzle is designed in such a way that the nozzle can be inserted at least partially into the spout of the spout film bag and also at least partially into the interior of the spout film bag, wherein the lateral surface of the part of the nozzle that can be inserted has a bulging design. The invention further relates to a method for inflating a spout film bag by using said nozzle, comprising the following steps: providing the nozzle; inserting the nozzle into the spout of the spout film bag and lowering the nozzle in the spout to a first position; after the first position has been reached, wherein the lateral surface of the inserted nozzle interacts with the internal form of the spout in such a way that the interior of the spout film bag is substantially sealed, introducing flushing or inflating air into the interior of the spout film bag by means of the nozzle.

A beverage bladder assembly for storing a beverage for drinking includes a bladder that is comprised of a fluid impermeable material to store a beverage for drinking. The bladder is comprised of a deformable material thereby facilitating the bladder to be collapsed for disposal when the beverage therein has been depleted. The bladder has a neck extending outwardly therefrom and the beverage is poured outwardly through the neck for drinking. A cover is removably bonded to the neck for closing the neck.

A dispensing baked good container assembly includes a container having a top and a bottom and a cavity between the top and the bottom configured to hold baked good ingredients. The container includes a closure member at the top configured to be opened. A pastry bag is configured to extend from the container. The pastry bag is initially packed in the cavity and configured to be deployed from the container after the container is opened. The pastry bag is open to the cavity such that items are configured to be passed through the cavity into the pastry bag after being deployed for mixing and dispensing of the baked good ingredients from the pastry bag.

In one aspect, a disposable container for hygienic dispensing of a consumable liquid is disclosed. The container comprises a bag made from a flexible, liquid-impermeable material and has a flexible body portion for containing a consumable liquid and a flexible neck portion with a hermetically sealed mouth. The mouth is for dispensing the consumable liquid upon when opened. The neck portion is in a stored position, tucked inside-out inside the body portion. The tucking results in a continuous fold in the bag. The container also comprises a closure for holding together opposite sides of the bag at the continuous fold to maintain the neck portion of the bag in the stored position, tucked inside-out within the body portion, and to shield the neck portion from external contaminants pending opening or removal of the closure and eversion of the neck portion into a dispensing position.

A sealed break-open package; the sealed package has: a first sheet of semi-rigid plastic material; a second sheet of flexible plastic material superimposed on and sealed to the first sheet to define a sealed pocket that contains a dose of a product; and a pre-weakened area that is created in a central area of the first sheet for guiding, following bending of the sealed package, controlled breakage of the first sheet at the pre-weakened area so as to form an outlet opening for the product through the first sheet. The first sheet has a U-shaped protuberance that extends from a side of the first sheet outside of the pocket and is arranged at the pre-weakened area.

A material supply device and a spout mounted in a bag body that can efficiently output a material in an accommodation space when the material accommodated in the accommodation space of the bag body is output using a squeeze unit such as rollers, and can inhibit a decrease in the strength of the bag body which is caused by contact between the squeeze unit and the spout. A material supply device according to the present invention includes a bag assembly including a bag body that includes an accommodation space which accommodates a material, and a spout that includes a passage which delivers the material in the accommodation space to an outside, and is mountable in the bag body; and a squeeze unit that squeezes the bag body toward the spout to move the material in the accommodation space toward the spout.
