摘要:
A carton constructed to permit the contents to be poured out over an upper corner. The top panel (18) includes a fold line (46) about which a corner closure flap (47) pivots. The corner flap includes a flange (45) formed by tear lines in portions of the adjacent side and end panels (12, 14). Additional layers of material in face-to-face contact with the inner surface of the side and end panels in the area of the closure flap provide edges over which the contents are poured. The closure flap fits tightly over the additional layers to hold it in place after it has been reclosed.

The invention relates to the field of divider sheets for stacked products, and the method of transferring these sheets from a stack. Prior art divider sheets are prone to adhere to each other and great care was needed to adjust the retainer bars for the divider sheet stack. The instant invention overcomes these disadvantages by providing the divider sheets with indentations (29) and aperatures (30) to prevent sheet adherence. Moreover, notches (25, 26) alternately engage stationary retaining pins (36, 36a) of the supply magazine (31) to permit high speed, continuous operation.
摘要:
A wrap-around carrier (10) with end panel flaps (28) that automatically close when the bottom panel flaps (42, 44) are set up for locking engagement. The end panel flaps (28) are foldably connected to the side panels (18) and to gusset panels (62) which are also foldably connected to a bottom panel flap. Upon folding the gusset panels (62) into engagement with the adjacent bottom panel flap, the end panel flaps are folded into closed position. The folded gusset panels are located between the bottoms of the packaged articles (B) and the bottom panel, thereby locking the end panel flaps in closed position.
摘要:
A down-article indicator (10) which automatically adjusts for the height difference of articles, such as bottles (90), when article size is changed for a new run on a machine (96) conveying articles. A pivotably mounted height sensing arm (20), located on one lane of the machine, downstream from an array of freely pivoting detecting arms (40), is connected by an adjustable mechanical linkage (70) to a pivoting bracket (62) holding a retro-reflective photo eye (61) in proper location with respect to the detecting arms so that the detecting arms do not break a light beam from the photo eye during normal operation. A non-upright article (92) will cause a detecting arm to pivot and break the light beam to stop the machine. As a new group of articles having a different height moves into the down-article indicating station, the height sensing arm automatically moves the photo eye to its proper location for the new height articles. The machine has a 'prime' mode which overrides a stop signal which may be sent by the photo eye while the transition between groups of articles passes through the machine.
摘要:
A basket-style article carrier (10) which exposes much of end packaged articles (B). The carrier has narrow side panels (24) which, with partition straps (38, 40), form article receiving cells. End cells are formed by the partition straps, side straps (28) extending out from the side panels and end straps (30) connected to the side straps. The partition straps and the end straps are connected to a central handle panel (12). The end straps and side straps contact only small portions of the articles, allowing the remainder of the end articles to be viewed.
摘要:
A carton flap folding apparatus includes a spaced, generally parallel, pair of knock-down arms (32) which are rotated in the direction of a path of travel (P) of groups of articles (G) to be packaged. The knock-down arms (32) are rotated into engagement with at least one open flap (45) of a carton blank carried by a group of articles (G), at substantially the same speed as the speed of the group of articles. The speed of the knock-down arms (32) is decreased with respect to the speed of the group of articles (G) prior to engaging the at least one open flap (45) of the carton blank, and increased with respect to the speed of the group of articles (G) for disengaging the knock-down arms (32) from the at least one hinged flap (45) of the carton blank.
摘要:
A packaging machine (5) for moving spaced groups of containers along a packaging line is disclosed. The packaging machine (5) includes a variable pitch lugged conveyor belt assembly (12) having a pair of equally spaced conveyor chains (61, 62) and a pair of side guides (17) mounted on a pair of accessory rails (14) movably supported on the packaging machine framework (7) along opposite sides of the packaging line. The conveyor chains (61, 62) are laterally movable. The side guides (17) and accessory rails (14) are simultaneously moved laterally as the conveyor chains (61, 62) are moved. Each conveyor chain (61, 62) includes spaced pop-up lug assemblies (63) with pop-up lugs (92) selectively reciprocated from lowered positions to raised positions extended above the conveyor chains (61, 62) for varying the pitch. Each conveyor chain (61, 62) includes plural modular table-top lugs (65) which are yieldably urged into position on an endless chain (84).
摘要:
A container formed by wrapping a slotted flexible sheet about rigid end panels having corner projections (38) that extend through the slots (44). The end panels are formed by a flap (14) foldably connected to the sheet which may be reinforced by other connected flaps (14', 14"). Additional reinforcement may be provided by end panel stiffener inserts (86). Stacking projections (24) on the end panels extend through slots (42) in the flexible sheet to maintain the sheet in place.
摘要:
An apparatus (10) for loading stacked article groups (14) into cartons (16) in a continuous motion cartoner assembly (12). The barrel cam loading apparatus (10) or article group transport mechanism (24) is particularly suited to loading article groups that are unstable or whose articles tend to spin and kick articles out of the carton. The article group transfer mechanism (10) loads the stacked group by having the lower article group (36) lead the upper article group (40) which tends to make the articles tip backward into a stable contact with the article group transfer mechanism, and by forming the upper article group into a nested configuration which has a thinner loading dimension and resists kicking out an article.
摘要:
A basket-style carrier (10) with means for maintaining the carrier open during loading (66, 70, 80). The carrier includes tabs (66, 70, 80) foldably connected to the end panel sections (58, 82) at one end of the carrier. When the tabs are folded in at substantially right angles to the end panel sections, they engage a vertical support member (14, 74) to prevent the carrier from closing. When the articles being loaded reach the tabs, they fold the tabs up against the inside face of the end panel sections. The articles themselves maintain the carriers open at that point and the tabs are no longer needed for that purpose.
