Abstract: A fitment sealing apparatus employs a high-speed continuous-motion conveyor for carton blanks and a rotary sealer for sealing fitments to the carton blanks by maintaining heat and pressure contact over a given duration through a prescribed turning angle. The rotary sealer is positioned adjacent an inside corner of two portions of the conveyor arranged at a right angle, and has four heating anvils spaced circumferentially at 90 degrees to each other. An adhesive applicator applies a layer of hot-melt adhesive between the fitment and carton blank which is formed into an excellent seal by the rotary sealer. For fitments of the flat, reclosable type, the apparatus includes a secondary adhesive applicator and a plowover bar to form the fitment in its folded-over configuration.

Abstract: A gas displacement device and method for substituting inert gas for ambient air in a gable-top paperboard carton prior to closing of an open top of the carton. The open top has first and second predetermined dimensions in mutually perpendicular directions. The device includes a source of inert gas, a channel for outputting a blanket of inert gas through an outlet and a conveyor for moving cartons in the first direction so that each open top passes under the outlet. The outlet has maximum dimensions in first and second mutually perpendicular directions which are respectively greater than the first predetermined dimension and less than the second predetermined dimension. The open top of the carton passes underneath the outlet with the directions of the first and second predetermined dimensions being oriented substantially parallel to the first and second directions respectively. The outlet has the shape of a rectangle with rounded corners.

Abstract: A head cleaning disk for cleaning magnetic transducer heads in flexible computer disk drives. The head cleaning disk comprises a top fibrous wiping layer having a blend of low melt point and high melt point fibers, an inner composite layer of a multi-layer thermoplastic opaque film having two outside reflective layers of low melt point polymer and two inner layers of metal and film, and a bottom fibrous wiping layer having a blend of low melt point and high melt point fibers. The top, inner and bottom layers are bonded together by passing them between a pair of heated rolls which are under pressure. The heat from the rolls melts the low melt point fibers in the top and bottom fibrous layers and the outside reflective thermoplastic polymer of the inner layer thusly securing the layers together. The top and bottom fibrous layers provide sufficient abrasivity so when they contact the transducer heads they will remove debris from them without the use of cleaning solutions.

Abstract: A curved log to be sawn lengthwise by a vertical saw blade is supported for a time, near its center of gravity, by a device which permits the log to rotate about its axis, and thus find an orientation at which the plane of the curve of the log axis is vertical, so as to maximize yield from the log. The device also includes drive sprockets which operate, at certain angular positions of the device, to move the log lengthwise.

Abstract: A paperboard article carrier suitable for modular construction. The complete carrier is adapted to carry four cans or bottles (a four pack) and is formed by assembling two identical two pack article carriers. The two pack article carriers are each formed of a single blank of paperboard which is folded and glued. Each two pack carrier includes a lower basket like portion and an upper, centrally positioned, handle fashioned from two layers of paperboard. One portion of each handle contains a pair of projecting friction latch tabs. The lower or basket portion of each two pack carrier is provided with a latching tongue and a latching recess, the tongue and recess of each being positioned at opposite ends of the basket. Each carrier may be separately employed as a two pack carrier. If desired, the carriers may be assembled to form a four pack carrier by placing the latching tongues into respective latching slots and by securing the friction latching tabs of the handle portions together.

Abstract: An apparatus and method for manufacturing partially cut (semi-converted) products in continuous roll form has input feeds for supplying a continuous web of material and a continuous transport web in parallel, feed rollers for incrementally advancing the two webs together to a cutting station where product units are partially cut in successive increments in a continuous strip, a scrap remover, and a station for winding up the cut product strip. The webs are unwound and the cut product strip is wound via dancer bars maintaining constant tension. The input webs have a width which is a multiple of the width of the product units so that multiple strips can be formed simultaneously. The invention is used to form semi-converted, micro diskette liners having connecting portions and indented cutouts marking the boundaries between units. The cutouts are overcut in one direction and also in an intersecting direction to obtain complete cuts despite slight variations in registration.

Abstract: A wrap-around carrier to package a linear series of gable-top liquid cartons is formed from a one piece paperboard blank conformed so that an end flap will cover a major area of an end of the erected carrier to inhibit damage, loss, or pilferage of an object such as a straw temporarily secured to an otherwise exposed side of a contained carton.The top panel is provided with a longitudinally running tear strip, conveniently wide enough to form a returnable card or a coupon, the coupon provided with advertising or other indicia on one or both of its surfaces.

Abstract: A hybrid nonwoven liner for a diskete holder is bonded and impregnated with a small amount of binder which is uniformly distributed throughout the fabric and comprises no more than 5% by weight and preferably between 1.5-3.0% by weight of the fabric. The low concentration of binder ensures that the liner surface does not become totally coated with plastic film that reduces cleaning ability, while also providing a high increase in tensile strength and a significant debris reduction. The binder solution preferably has a high surface tension (low surfactant level), so that the binder beads and becomes dried at junction points of the fibers and evenly distributed throughout the fabric. The low level of surfactant ensures a low risk of chemical attack of the disk media surface.

There is also a cup holder which may be selectively mounted on the carton or which may be supported independently of the beverage dispenser adjacent the beverage dispenser.

Abstract: A corner post construction fashioned from corrugated paperboard of single or more thickness. The corner post is made from a unitary blank of corrugated paperboard, the blank being generally rectangular and provided with three parallel slit scorelines running generally longitudinally of the blank. The scorelines define four generally rectangular panels, with the two innermost panels being of substantially the same width, but with the first and second outermost panels being of respectively greater and different widths. The slit scorelines are reverse cut, with the middle coming in from one surface of the unitary blank and the outer two slit scorelines coming in from the other surface. All three scorelines extend completely through the blank, except for the outermost or facing layers of the corrugated board. After slit scoring, the two outermost panels are glued to their respective next adjacent innermost panels to form the corner post in its storage or shipping condition.

The front wall of the lower clamshell half carriers a latch release panel, the latter carrying a horizontally despaired latching tongue normally engaged in the latching aperture to maintain the clamshell in a closed configuration. The latch release panel is normally resiliently biased to maintain the latch tongue engaged. The front wall of the upper clamshell half is provided with a recess along a free edge, the recess permitting direct finger force to be applied to the latch release panel to open the carton by disengaging the latch.

Abstract: A clamshell or other hinged top cover type carton for hamburgers is provided with a divider sheet formed from paperboard or a paperboard laminate. The ends of the divider sheet extend laterally beyond the side edges of the carton. A bun heel and hot hamburger patty are located in the lower half of the container and a bun crown and various toppings are located in the top container half. The divider sheet separates the hot meat patty from the cooler toppings. For hamburger consumption, the user pulls a laterally extending edge of the divider sheet laterally away from the carton, the bun crown and toppings fall on to the hot hamburger patty and bun heel, thereby preparing the hamburger sandwich. The consumer now opens the carton to gain access to the sandwich.

Abstract: A paperboard carton formed from a unitary blank of paperboard. A side flap of the carton bottom is overlapped with and sealed to a side flap of the top cover. At least one of these flaps is provided with spaced abseal (adhesion resistant) areas. The interabseal areas are provided with adhesive to seal against the other, overlapping flap. The interabseal areas are bordered by cut lines extending partially through the paperboard, and are preferably embossed so as to be raised from the remaining flap area. The other front and side flaps are conventionally sealed together by an adhesive, such as a heat activated PET coating on the paperboard surface. To effect opening, these two flaps are pulled apart with the adhered together, interabseal are a of one of these flaps delaminating by virtue of the cut lines, the latter extending completely through the PET coating.

Abstract: A paperboard partition having particular utility as a partition for spacing and supporting items in a paper bag or any suitable holder is formed from a unitary blank of paperboard. The blank is die cut and provided with a plurality of fold lines. The die cuts define a plurality of locking tabs and also define apertures for receiving the locking tabs when the partition is erected. Two of the panels defined by the fold lines and die cuts are each provided with a spot of glue or other adhesive. Upon initial folding of the blank those panels, termed adhesive panels, which have been provided with glue spots, are attached to corresponding panels. The partition is formed in such a manner that it is collapsed to flat configuration for shipment and/or storage. For use, the user erects the folded partition by unfolding, i.e., spreading several of the panels apart from each other, with the partition then being placed into a paper bag or other holder.

Abstract: A paperboard tray and unitary blank for forming it. Two of the tray blanks may be joined in tandem to form, after erection, a clamshell type carton. The tray is provided with cooperating latching tongues and latching slits to maintain it erected. The specific form of the latching tongues and slits enables the tray sides to tilt outwardly after initial tongue and slit engagement and thus permit stacking. The use of the tongue and slit of this invention also permits tray formation without the need of adhesives, thus permitting safe use of the tray or clamshell carton in serving food, as at the retail level.

Abstract: A tube type carton formed from a unitary blank of paperboard and having at each end closure panels defined by a pair of opposed dust flaps and opposed major and minor closure flaps. The major flaps and two opposite side wall panels of the four side panels are trapezoidal. The remaining two opposite side wall panels are square but of different size. A pair of rectangular interior tucking panels joins one edge of the smaller square side wall panel to the shortest edge of one of the two opposite trapezoidal side wall panels, these interior panels being tucked into the interior of the carton. By virtue of the tucking, the cross-section of the tube is changed from rectangular to trapezoidal. The fully erected configuration of the carton is that of a truncated, right, four-sided, rectangular pyramid.

Abstract: A method and apparatus for attaching a skirted end closure to a tubular paperboard container, the container having a continuous lapped seam from one end to the other. The interior surface of the container is layered with a thermoplastic, and the container wall includes a layer of metal foil. An annular induction coil is placed near the annular surface of contact between the end closure skirt and an end region of the container interior surface. Upon activation of the induction coil, the metal foil is heated by the usual eddy current effect, to thus soften the thermoplastic and adhere the end closure skirt to the container. The specific improvement in this combination is the addition to the coil of a field intensifier in the region of the lapped seam. The action of the intensifier partially overcomes the lessened heating effect which naturally occurs at the ends of the lapped seam.

Abstract: A paperboard carton and plastic pour spout fitment construction for cartons adapted to carry powdered or granular material, particularly foodstuffs. A side wall of the carton is provided with a precut opening to receive the separate fitment. The periphery of the sides of the pour spout bottom wall must be broken from the surrounding fitment by the consumer upon initial use, to permit the spout to pivot for dispensing. The spout is thus held against accidental opening during shipping and handling prior to use, and further, such breaking is automatically tamper evident. The fitment is attached to a side wall of the carton by use of an adhesive or by a plurality of rivet stakes integral with the spout. The rivet stakes are received in complementary punctures bordering the precut opening. The use of plastic for the pour spout fitment insures against metal particles contaminating the contents of the carton.
