To obtain a paper container, which allows an upper end portion of a body panel to be reliably dented at the time of unsealing of the paper container so as to be easily unsealed, on the body panel (7), a first auxiliary folding line (43) having a downwardly curved shape is formed to have end portions (41, 42) arranged so as to connect the reference points (40) to each other, or connect together positions that are near the reference points (40) on the body vertical folding lines (3, 4) or positions that are away from the body vertical folding lines (3, 4) and below the reference points (40) in a height direction of each of the body vertical folding lines.

A method of producing a gable-top paper or paper-board based packaging container is disclosed, the packaging container having a plurality of top-closure sub-panels, including a top-closure sub-panel (132) configured to form a pouring spout of the packaging container when the packaging container is in an open position, the top-closure sub-panel being configured to form a pouring spout comprising top-fin panel sections (182a, 182b) being at least partially hot-sealed to each other prior to a first opening of the packaging container, the top-fin panel sections abutting one another in a contact region when the packaging container is in a closed position. The method comprises the steps of: producing a blank (100) from a laminate packaging material having an outside heat sealable layer; and treating the outside heat sealable layer in a sub-region (192a, 192b) of at least one of said top-fin panel sections (182a, 182b) reducing or eliminating the heat-sealing capacity of the outside heat sealable layer in the sub-region. A related blank and a packaging container produced from such a blank is also disclosed.

This invention relates to a container comprising and outer shell and an inner lining, to a method of construction of such a container and to components used in the construction of such a container. A container comprises an outer shell made from a first material comprising paperboard, and an inner lining made from a second material comprising a polymeric or metallic material, the lining defining an internal volume for holding a liquid, and the lining being adhered to the shell, wherein, the outer shell includes a line of weakness extending around at least part of the periphery of the shell and defining a first portion of the shell on one side of said line and a second portion of the shell on the other side of said line, the line of weakness permitting the first portion of the shell to be separated from the second portion of the shell, and wherein, the lining is adhered to the shell in said first portion and the lining extends into to said second portion of the shell.

A dual-opening carton has a front, rear, and opposing side panels. A flap extends over the top of the carton, allowing the top to be opened and re-closed. A score line extends around the carton to facilitate the removal of a top portion of the carton. The score line has segments extending along the front panel, the rear panel, and rear portions of the side panels that have a relatively low cut length to land length ratios that maintain relatively high structural integrity. The score line also has segments extending along the front of the side panels have a relatively high cut length to land length ratio to facilitate tear propagation. The score line extending along the side panels is angled so that a pull force vector removing the top portion of the carton runs along a plane generally parallel to the score line.

A refillable container includes: an inner container having a suction port at a center of an upper surface portion and a bottom portion with a pyramid shape having a deepest portion at a center of the bottom portion; a support member configured to hold the bottom portion of the inner container to support the inner container in a standing state; a lid member fitted to an outer periphery of the inner container; a discharge pump on a top surface portion of the lid member, the discharge pump including a suction tube inserted through the suction port into the inner container; and a positioning device for positioning the inner container in a vertical direction such that a distal end of the suction tube is located in the pyramid shape of the bottom portion of the inner container.

Methods and apparatuses are disclosed for processing cartons that include steps such as embossing the top opening of cartons for packaging liquid food. Embossing the top opening of cartons may reduce the force required to open the carton in both vertical and horizontal direction and minimize the amount of fibers remaining in the pouring spout after the carton has been opened.

A composite pack for filling liquid material having an interior member as a non-self-standing type liquid material filling package member of filling a liquid material and an exterior member capable of stably holding the interior member, includes a bag-shaped interior member formed by the liquid material into a soft package bag and an exterior member for housing the interior member and including a cylindrical body, a bottom wall disposed at a lower end of the cylindrical body and an opening portion formed in an upper end of the cylindrical body. The interior member includes a sheet-like nozzle for pouring the liquid material protruded in an upper end portion or a side end upper portion of the package bag, and the exterior member includes at the opening portion a sealing structure unit having a top face wall closing the opening portion and plural vertical rubs standing from the top face wall.

A fluid carton assembly for dispensing and storing a liquid beverage includes a beverage carton for storing a liquid beverage. The beverage carton has a pair of flaps each being positionable in an open position to pour the liquid beverage. The flaps are positionable in a closed position to contain the liquid beverage. A slide is slidably coupled to each of the flaps. The slide is slidable into a closing position thereby retaining the flaps in the closed position. The slide is slidable into an opening position thereby facilitating the flaps to be positioned in the open position.

A storage container having a backup element for spout formation includes a carton that is gable top type. The carton is configured to be opened by first pushing a pair of gables from a front toward a back of the carton so that the gables separate a first seam of a top of the carton and, secondly, by pushing the gables toward the front with concurrent squeezing to separate a second seam to form a spout. A tab that is coupled to an inner face of a respective gable proximate to an upper edge and a midpoint of the pair of gables is configured to be grasped in digits of a hand of a user. The user can pull the tab to separate the second seam in event the pushing of the gables toward the front of the carton with concurrent squeezing does not separate the second seam.

A refillable container including: a liquid inner container (100) having a suction port formed at a center of an upper surface portion and a bottom portion (103) formed into a pyramid shape having a deepest portion at a center of the bottom portion; a support member (2) configured to hold the bottom portion of the liquid inner container to support the liquid inner container in a standing state; a lid member (4) fitted to an outer periphery of the liquid inner container; a discharge pump (7) provided on a top surface portion of the lid member and including a suction tube (6) inserted through the suction port into the liquid container; and a positioning device (8) for positioning a position of the liquid inner container in a vertical direction is determined such that a distal end of the suction tube is located in the pyramid shape of the bottom portion.
