A squeezer and fluid discharge system and method are disclosed. The fluid discharge system includes a container, a liner bag, a squeezing device and a driving device, the liner bag is installed in the container, and the driving device is connected to the squeezing device and used to drive the squeezing device. The squeezing device comprises at least two rollers, and the liner bag is formed by welding a front panel and a rear panel and is provided with a discharge port which is arranged adjacent to the weld line at the bottom of the liner bag.

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.

A container assembly for flowable materials, the container assembly comprising: a reusable outer supporting container; and a disposable inner plastic liner; wherein the reusable outer supporting container comprises an outlet pipe comprising a first outlet pipe section connected to the reusable outer supporting container and a second outlet pipe section releasably connectable to the first outlet pipe section, wherein the second outlet pipe section comprises a valve for selectively closing off the second outlet pipe section, and wherein at least one of the first outlet pipe section and the second outlet pipe section comprises an annular recess; and wherein the disposable inner plastic liner comprises a tubular outlet portion, wherein the tubular outlet portion comprises an outer flange configured to be captured between the first outlet pipe section and the second outlet pipe section, and further wherein the outer flange of the tubular outlet portion comprises an annular protrusion configured to be received in the annular recess when the outer flange is captured between the first outlet pipe section and the second outlet pipe section.

Box blanks, bag-in-box systems, and methods for forming bag-in-box systems from box blanks. The box blanks (100) include portions and flaps configured to fold and interlock with each other so as to improve structural integrity and reduce lateral deformation, have cross-corrugation and simplified fabrication, and have fewer or no internal edges or corners that may jeopardize the integrity of a bag of liquid or pourable powder contained therein.

A container includes: a skeleton shell defining a container body of the container, the skeleton shell being formed from a recycled and/or biodegradable pulp material; and, a bag or liner removably disposed within the skeleton shell. Wherein the skeleton shell includes at least one separation feature that facilitates separation of the skeleton shell from the bag or liner.

Corrugated box assemblies, blanks, and systems for individually shipping a bag of liquid stored therein and converting an inner portion into a bag-in-box dispenser are provided. An example box assembly comprises an inner portion comprising a plurality of walls. The inner portion includes an interior configured to receive and store the bag of liquid, which may range from about 3 to 6 gallons. The inner portion further includes a removable perforation feature defined by a series of perforations on at least one of a front wall and a front top flap extending from the front wall. A top portion and a bottom portion each comprise a plurality of walls that, when formed, define an opening sized to fit around the inner portion. The box assembly may be configured to pass individual box shipping test standards, such as ISTA and SIOC test standards. Methods of forming the box assembly are also provided.

This invention discloses a fluid discharge system and the squeezer thereof. The squeezer includes a pair of rolling shafts, a driving device, and a mounting bracket, wherein the pair of rolling shafts is rotatably mounted on the mounting bracket. Each rolling shaft has a mounting part at each of both ends and a squeezing segment located between the mounting parts. A pair of rolling shafts can operatively clamp an object to be clamped between the squeezing segments and can rotate oppositely through a driving device to apply a squeezing force to the object clamped. The squeezing segment includes a supporting shaft and an elastic body provided around the supporting shaft. The squeezer also has a protective device for protecting the elastic body at the end of the squeezing segment. The discharge system provided by this invention is a zero-residue discharge system needing not to hanging the liner bag, and has a simple structure, a good manufacturing process, simple operation, and cost savings.

A 3-D flexible bag to be filled with a biopharmaceutical product is formed by assembling of two wall elements and two gussets. At least one connection port is provided, for filling and/or emptying. A substantially parallelepipedal configuration is obtained in a filled state thanks to the unfolding of the gussets combined with the folding of flaps of the two wall elements. A transverse weld, formed at one end, connects the two wall elements of the bag and extends continuously, keeping in a folded-flat state:—an elongate edge portion of one gusset;—an elongate edge portion of the other gusset. This transverse weld has a length corresponding to a determined dimension of the flexible bag in the parallelepipedal configuration.
