A flexible container is provided. The flexible container includes four panels. The four panels form (i) a body portion; (ii) a neck portion, and a flare portion that extends from the neck portion; (iii) a tapered transition portion between the body portion and the neck portion; and (iv) the neck portion has a reduced width. The flare portion has an expanded end. The width of the flare portion gradually increases from the neck portion to the expanded end.

At least one of a horn or an anvil includes protrusions that protrude from a facing surface thereof. Two panel parts and a gusset part folded and interposed between the panel parts are sandwiched and compressed by the horn and the anvil. Two portions of the gusset part are welded to each other by ultrasonic vibration of the horn during the sandwiching and compressing.

A method of manufacturing an SOS bag of indefinite length is disclosed including, as a preliminary step, providing a gusseted tube of indefinite length. In a series of steps, the gusseted tube may be cut, trimmed, folded, and sealed to create a unique bottom for an SOS bag. The bottoms of the front panel and the rear panel may be cut so as to permit the inward folding of the bottoms of the gussets of the gusseted tube, such that the bottoms of the gussets overlap. A front panel of the gusseted tube may then undergo a trimming and folding and heat sealing, followed by the rear panel of the gusseted tube undergoing a trimming and folding and heat sealing. The disclosure additionally includes bags manufactured by the method disclosed herein, as well as SOS bags having the unique construction disclosed herein.

A method of manufacturing an SOS bag of indefinite length is disclosed including, as a preliminary step, providing a gusseted tube of indefinite length. In a series of steps, the gusseted tube may be folded inwardly at its base to create front and rear flaps that are then folded about fold lines to create a folded bottom gusseted tube. A rectangular patch may then be applied thereto in a series of steps, including for example hot air welding and/or ultrasonic welding, to complete an embodiment of a bag of the disclosure, one having a unique bottom for an SOS bag. The disclosure additionally includes bags manufactured by the method disclosed herein, as well as SOS bags having the unique construction disclosed herein.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a single sealing zone, and a weakening zone disposed within the single sealing zone. The single sealing zone may be a heated perforator, includes a heating wire. The heating wire may be an NiCr wire stitched into the heater, and be disposed on a cap or on the seal bar. The weakening zone may create a line of weakness that is uniform or varies in intensity. The sealing zone may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.

First and second panel webs are superposed on each other and fed in their longitudinal direction. After a side gusset is temporarily fixed to the second panel web, the side gusset is divided by a dividing device to form a pair of open edges. The open edges are aligned with a line of weakness of the first panel web when the first and second panel webs are superposed on each other. The side gusset is temporarily sealed to the first and second panel webs by a temporary seal device to form temporary sealed sections. The first panel web is guided to be divided along its line of weakness and to be folded on the sides of its division edges. This guiding of the panel web and the temporary sealed sections cause the side gusset to be opened at the open edges to form open surfaces. An end face web is then disposed on the panel web to be superposed on folded parts of the panel web and the open surfaces of the side gusset.

The invention relates to an inflatable pouch comprising an inflatable pouch with an interior pocket; an air valve attached to the inflatable body; a zipper configured to close an opening of the inflatable body; at least one clasp attached to the pouch; a rope connecting each clasps of the at least one clasp; a rope adjuster attached to the rope; and at least one ring attached to each clasp of the at least one clasp. The invention also relates to a method for creating an inflatable pouch.
