A system and method for producing a medical bag with an HF welder that uses upper and lower dies each having a plurality of electrode lamellae arranged such that they are alternatingly polarized relative to adjacent lamellae and opposing lamellae. Interspersed dielectric materials may be used to impart contours onto the film material to produce a patterned bag.

The present disclosure provides a flexible pouch. In an embodiment, the flexible pouch includes opposing flexible films. The flexible films define a common peripheral edge. A microcapillary strip is sealed between the opposing flexible films. A first side of the microcapillary strip is located at a first side of the common peripheral edge and a second side of the microcapillary strip located at a second side of the common peripheral edge. A peripheral seal extends along at least a portion of the common peripheral edge. The peripheral seal comprises a sealed microcapillary segment. The peripheral seal forms a closed flexible pouch having a storage compartment. A liquid is present in the storage compartment.

A consumption packet includes a bag and a dispensing arrangement. The bag includes a first bag wall and a second bag wall defining a cavity between the first and second bag walls. The bag further has an enclosable area defined at the first bag wall and a pouch opening formed within the enclosable area. The dispensing arrangement includes a sealing flap extended from the second bag wall and folded on the first bag wall to enclose the enclosable area thereof so as to seal the pouch opening by the sealing flap, wherein the sealing flap is unfolded from the enclosable area to unseal the pouch opening.

A method for three-dimensionally forming a resin packaging member. The resin packaging member is heated to a temperature not higher than the Vicat softening temperature of the packaging member, and then compression shaping is conducted at a temperature not lower than room temperature and not higher than the Vicat softening temperature so as to form a three-dimensionally shaped portion with a large protrusion.

A package or container is disclosed that includes an opening device in conjunction with a self-sealing valve for facilitating opening of the package and for dispensing fluids in a controlled manner. In one embodiment, the opening device can comprise a breachable bubble. The breachable bubble can be in communication with a fluid channel that operates in conjunction with the self-sealing valve. The package can include a folded portion for sealing the fluid channel and allowing the bubble to be breached when a user applies pressure. Once the bubble is breached, the folded portion can be unfolded for dispensing a fluid.

A package and method of creating a package for dispensing a product are disclosed. The package comprises a flexible pouch comprising an elongated spout and a flowable product disposed within the pouch. A spout retainer is disposed on an exterior surface of the pouch adjacent to the spout, with opposite ends of the spout retainer attached to the exterior surface of the pouch to form two bridges, each of the bridges having a bridge width that is wider than a spout width to allow the spout to pass underneath each of the two bridges. The package may be manufactured on a vertical form-fill-seal machine where the pouch and spout retainer are formed from different supplies of film material.

A package designed to prevent the leakage of its contents and to capture any leaked contents within a package reservoir, while permitting the package to be sealed for later access to the contents of the package.

A woven laminated plastic bag having a weakened portion is provided. The weakened portion is generally defined by a plurality of perforations in the bag. In various aspects the bag can be fabricated from woven polypropylene and/or polyethylene layer which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.

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 spout for use with a flexible bag and a flexible bag having a spout. The spout includes a threadform that extends about the outer surface. The threadform includes opposing threadforms that are of different configurations. Additionally, the insert member includes a poppet and a spring member to maintain the poppet in a configuration that precludes the passage of fluid therethrough.
