摘要:
A machine for forming a container from a blank of sheet material including a glue panel and an overlap panel includes a frame, a mandrel mounted to the frame, a glue panel folder assembly, and a glue panel presser assembly. The mandrel has an external shape complimentary to an internal shape of at least a portion of the container. The glue panel folder assembly includes an actuator and a glue panel folding member operatively coupled to the actuator. The actuator is configured to cause the glue panel folding member to move in a curvilinear path of motion, contact the glue panel, and move the glue panel into at least partial contact with the mandrel. The glue panel presser assembly is configured to press the overlap panel into face-to-face contact with the glue panel to form a manufacturer joint of the container.

A food-safe container (2) for liquids is composed of a tubular body (3) referable to a longitudinal axis (2a), and a neck (7) presenting a quadrangular base (16) fastened coaxially to an open top end (5) of the tubular body (3) afforded by a frustopyramidal connecting portion (6) of which the four tapered corner edges are pinched initially and left with four relative fins (22); the container (2) is formed by a machine (1) equipped with a folding and sealing or welding unit (24) including twin pairs of arms (26) by which the single fins (22) are folded flat against corresponding side walls (6a, 6b, 6c, 6d) of the connecting portion (6), and a pair of heat-sealers or ultrasonic welders (29) operating in conjunction with the arms (26), by which the fins (22) flattened against the respective side walls (6a, 6b, 6c, 6d) are secured in place.

A method of and a device for folding a bottom of a package (13), which comprises a sleeve (14) of packaging material with a transversal seal (33) in the end of the bottom forming portion of the package (13), said portion having the shape of a fin (15), comprises the steps of folding the fin (15) and forming primary flaps (31), breaking corners on the folded fin (15) between the primary flaps (31) and the edge between the part of the sleeve (14) forming the bottom and the rest of the sleeve (14), such that secondary flaps (32) are folded in between the primary flaps (31) and the fin (15), the secondary flaps (32) thereby being folded essentially towards each other, folding the primary flaps (31) towards each other, and pressing the primary flaps (31) towards the remaining part of the bottom forming part of the sleeve (14).

A heating device for heat-sealing bottom portions of containers has a hot air nozzle 62. The nozzle 62 is positionable as opposed to a bottom forming end portion 14 of a tubular blank 11 of square cross section as fitted around an intermittently drivable mandrel 52 for heating a region of the blank end portion. The nozzle 62 is movable toward or away from the end portion 14 on the axis of the blank 11. The nozzle 62 has orifices 101, 102, 131, 132, 133 directed toward a plurality of parts within the region when the nozzle is positioned close to the end portion. Among the orifices 101, 102, 131, 132, 133 of the nozzle 62, those 101, 131 directed toward the part of the region remote from an extremity of the blank when the nozzle is so positioned have a greater open area ratio than those 102, 133 directed toward the part of the region proximate to the blank extremity when the nozzle is so positioned.
摘要:
A carton having a primary elevated bottom portion extending along the length of an exposed raw paperboard edge to protect the carton and to prevent moisture absorption. The carton also having a secondary elevated bottom portion substantially within the primary elevated portion and having an elevation greater than the primary elevated bottom portion. Additional elevated portions are provided for additional raw paperboard edges on the bottom of the carton. The present invention alleviates the problem of cartons having soggy bottoms since the point of absorption, the raw paperboard edge, is elevated above the moisture which may be present during distribution from the packaging machine to the retailer. The elevated bottom portion is actually inverted into the carton with planar portions resting on the surface to support the carton.
摘要:
A single generally rectangular blank which can be formed into a paperboard package. The four corners of the blank are trihedral. The blank is center folded. The width of a first portion of the blank, measured parallel to the centerfold, is greater than a second portion of the blank. The blank is sealed on the two sides adjacent the centerfold to form an open package, which is then filled. The side opposite the centerfold is then sealed to close the package, forming a parallelepiped container. The seals are fin seals. The fin seal opposite the centerfold of the blank overlaps the two seals adjacent the centerfold. The three fin seals are folded flat against the sides of the package. The package may be provided with an opening through the blank. A tab may be provided to completely cover and seal around the opening in the package. The tab includes a grip portion which, when pulled upwardly, lifts the tab away from around the opening in the package. As the tab is pulled upwardly, an outer laminate layer tears away from an inner paper core of the package in the region of the seal between the tab and the package, uncovering the opening in the package. The tab will remain hingedly connected to the package along a rear tongue portion.

In the manufacture of (cigarette) packets, especially of the soft-case type, the handling of critical, namely thin, packaging material on powerful packaging machines is problematic. A holding disc (26), to the peripheral surface (40) of which the blank (12) is adjacent, and a transverse supporting and conveying member (34) which is attached to the holding disc (26) and grasps a front end of the blank (12) by means of suction air, serve to lead blanks (12) to a rotary folding unit (10) and to take the blanks (12) by means of mandrels (11).
摘要:
A machine for producing containers comprises processing stations with components adaptable to the shape and size of the material sections used for the container. In the case of a change in form, in particular a change in the format of the sections of material to be used, it is necessary to change the relevant adaptable components. Instead of the conventional approach where the new components must be fine-tuned after an exchange has taken place, fitting surfaces are provided at the processing stations, against which a section of the adaptable components can always be placed in the same position. Therefore, time-consuming installation of exchangeable machine components is avoided.

The present invention forms and seals the top end of a container prior to filling and bottom sealing. The top end may have a fitment attached thereon at a variety of different positions on a form, fill and seal packaging machine. The fitment may be a screw cap, a push-in, a flip-cap type or similar fitments. The container may be a flat top, tetrahedral or similar type container. The fitment may be applied on the exterior or the interior of the container.
摘要:
The combination of a carrier for a container, a squaring plate, a drive for the squaring plate, and a sealing assembly. The carrier accepts a container having first and second spaced flat walls that are substantially parallel to each other with the container in an erected state and third and fourth walls each connecting between the first and second flat walls. The carrier has a first edge against which the first wall of the container can be abutted so that the first wall is thereby supported in a first orientation with the container operatively held by the carrier. The squaring plate is guided in movement relative to the carrier towards the first edge. The squaring plate has a guide edge for engaging the second wall of the container operatively held by the carrier as the guide edge moves relative to the carrier towards the first edge and thereby repositioning the second wall relative to the first wall as an incident of which the first wall is urged toward the first orientation and the first and second walls are urged into substantially parallel relationship with each other. The sealing assembly has a sealer element that is guidingly advanced towards and against a part of the container operatively held by the carrier to thereby reconfigure and close the part of the container operatively held by the carrier.
