A blank used for making a rapidly erected and collapsible container is disclosed. The container is movable between a flat configuration and a box configuration. The blank comprises a primary panel and a secondary panel, which are hingedly coupled to each other. The secondary panel is hingedly coupled to a secondary flap. The secondary flap is hingedly coupled to a terminal portion. The terminal portion is hingedly coupled to a tab. The tab is configured to fold towards the terminal portion. The secondary flap is configured to fold towards the secondary panel. The tab is configured to connect to the primary panel. Embodiments foster a blank used for making a container that rapidly, easily, and conveniently transitions from a flat configuration to being ready for use in a box configuration. Moreover, the container provides speed and efficiency without compromising cost effectiveness and structural integrity.

A gusset preheating assembly and a method of using the same. The assembly includes a heating gun assembly mounted on a frame. Spreader rods open up a gap in a bag's gusset and nozzles blow warmed air into the gap. Orthogonally arranged first and second hydraulic members are operatively engaged with heating gun assembly and are activated to move the heating gun assembly vertically or horizontally. Hot air blowing into the gap from the nozzle relaxes the gusset. Pressure is applied to the relaxed gusset, thereby reducing the thickness of the gusset region of the bag. The reduction in thickness makes it possible to increase the number of gusseted bags that are packaged in a container or on a roll.

The invention relates to a pouch-type bag made of paper having a first ply and a second ply, which are connected to one another on their lateral edges and form a filling space, wherein, at its closed end, the pouch-type bag comprises a block-type base or cross-type base and, at its open end via which the filling space can be filled, the lateral edges of the first and second plies terminate on the same plane, wherein at least one sheet is connected to the first ply, which sheet extends beyond the lateral edges of the first and second plies, wherein the sheet is arranged in particular on the side of the first ply facing away from the filling space.

A foldable bag comprises a front sheet and a back sheet which are circumferentially joined to each other. The bag is disposed in a folded condition in which the bag has a reversed T-shape including a bottom and an upward portion extending upwardly from the bottom. In the folded condition of the bag, upward portion side edges are inwardly creased between the front sheet and the back sheet such that they face to each other. At the bottom, an inner bottom edge portion extends substantially within a plane of the upward portion and each of outer bottom edge portions extend substantially parallel above the inner bottom edge portion.

A flat mailing envelope form for encapsulating an insert by an automated paper folding machine, includes a rectangular front panel with a seal flap fold edge, a bottom fold edge opposite the seal flap fold edge, a first side fold edge, and a second side fold edge opposite the first side edge. A back panel extends from the front panel bottom fold edge includes a back panel seal cohesive region, a first wing cohesive region, and a second wing cohesive region. A seal flap extends from the front panel seal flap fold edge includes a seal flap cohesive region configured to mate with the back panel seal cohesive region. First and second wings with cohesive regions extend from the front panel.

The invention relates to a bag (10) comprising a front wall (11) and a back wall (12) arranged parallel to the front wall (11), a bottom (13) that can be folded into the plane of the walls (11, 12), such that a filling chamber (14) results that is open on one side, and a pair of carrying handles (31) that is attached on the front wall (11) and the back wall (12). According to the invention, the pair of carrying handles (31) comprises a folding line (15) in the filling space (14), such that the pair of carrying handles (31) can be brought into a usage position (1) and in a rest position (2), wherein in the rest position (2) the pair of carrying handles (31) is entirely folded back inside the filling chamber (14) and in the usage position (1) the pair of carrying handles (31) protrudes at least in certain areas from the filling space (14).

A rectangular-bottomed packaging bag (1) is a rectangular-bottomed packaging bag formed by folding a sheet material member and includes a rectangular shaped bottom (2) a front (3) and a rear (4) rising from two facing sides of the bottom (2), and a pair of sides (5) connecting the front (3) and the rear (4). The pair of sides (5) each include a first region (31) positioned on the front (3) side, a second region (32) positioned on the rear (4) side, a side joining portion (33) joining the first region (31) and the second region (32), and an inclined joining portion (34) inclined to the bottom (2) side from the side joining portion (33) toward one of the front (3) and the rear (4) and joining the sheet material member of the first region (31) and the second region (32) overlapping each other in a direction of thickness.

A blank used for making a rapidly erected and collapsible container is disclosed. The container is movable between a flat configuration and a box configuration. The blank comprises a primary panel and a secondary panel, which are hingedly coupled to each other. The secondary panel is hingedly coupled to a secondary flap. The secondary flap is hingedly coupled to a terminal portion. The terminal portion is hingedly coupled to a tab. The tab is configured to fold towards the terminal portion. The secondary flap is configured to fold towards the secondary panel. The tab is configured to connect to the primary panel. Embodiments foster a blank used for making a container that rapidly, easily, and conveniently transitions from a flat configuration to being ready for use in a box configuration. Moreover, the container provides speed and efficiency without compromising cost effectiveness and structural integrity.

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 cut, folded, and sealed to create a unique bottom for an SOS bag. The bottom of the tube includes a center flap flanked by two bottom flaps, where the center flap may be heat sealed onto a bottom flap. The disclosure additionally includes bags manufactured by the method disclosed herein, as well as SOS bags having the unique construction disclosed herein.
