Abstract: A two way mailer is formed from a single blank of sheet material, and has separably interconnected forwarding and return envelopes sharing a common rear panel. The return envelope is separable from the forwarding envelope along perforated lines located exclusively or substantially exclusively outside of the front panel of the forwarding envelope. Vulnerable segments of the perforated lines are securely overlapped by the front closure flap of the forwarding envelope.

Abstract: A suspendable folder is disclosed having a front panel and a back panel with their bottom edges and a segment of each of their lateral edges secured to one another. A segment of each pair of lateral edges secured to one another is defined by two points, the first of which is near the bottom edge of each panel. The second, upper point is spaced from the first point by a distance preferably selected from the range of approximately one half to two thirds the height of the back panel. At or near the second upper point, a circular radius cut is provided to assist in distributing tearing forces across a large area of both the front panel and back panel. At least one transverse score line is also provided above the radius cut in the front panel to permit easier opening and closing of the folder without tearing.

Abstract: A bag with an openable mouth carries a reclosable extruded plastic zipper inside the mouth. The zipper has complementary profiles separably interlockable in a closed condition of the zipper. A gasket flange structure is separably sealingly grippingly interengageable by and between the profiles in the closed condition of the zipper, and may also serve as a tamper evident or tamper discouraging device.

Abstract: A shipping container for shipping bulk loads of pelletized, granular, powdered or other particulate material including an outer corrugated box and an inner cylindrical paper cylinder extending to the inner walls of the box. The container is characterized by its significantly increased resistance to outward bulging of the side walls by the weight of the material contained therein.

Abstract: A box structure with increased resistance to the opening of its base due to the weight of its contents has in the closure tab for its base a shaped notch which when the box is closed forms a slot parallel and adjacent to the folding line of said tab. From each of the relative box closure tabs, in correspondence with said slot, there projects a tooth which extends to touch the inner side wall of the box, the width of said teeth being just smaller than the length of the slot.

Abstract: The mailing system includes an elongated single paper ply folded along spaced parallel longitudinal foldlines to form flaps which overlie an insert disposed between the flaps and a central web portion of the first ply. The flaps terminate short of one another and a second ply of transparent material is adhesively secured between the flaps to provide an address window for the insert. The end margins of the flaps and second ply on the one hand and the central web portion on the other hand are adhesively secured one to the other to seal the mailer. Transverse lines of perforations are provided inset of the end seals to enable the mailer to be opened and the insert extracted.

Abstract: An easy open pouch is formed from front and back thin films by a seal formed between the films. The seal defines a product storage chamber and a dispensing cavity between the films. The seal completely surrounds the product storage chamber. An opening to the exterior of the pouch is formed in the seal in the dispensing cavity. The product storage chamber and the dispensing cavity are located adjacent to one another with a common wall located between them. The common wall is formed as a part of the seal and is frangible in response to a pressure differential between the product storage chamber and the dispensing cavity. Upon creating a pressure differential between the product storage area and the dispensing cavity the seal across the common wall delaminates to join the product storage chamber to the dispensing cavity. Product can then be dispensed from the product storage chamber through the dispensing cavity and out of the dispensing cavity opening.

Abstract: Disclosed are cartons having a carton end closure having an easy open pull tab feature, a pour spout feature and reclosure feature. The cartons have siftproof corners notwithstanding eliminating an inner liner. The closure is fabricated from two defined major end flaps and a minor or side end flap. The major end flaps are defined by cuts, score lines and both transverse and longitudinal adhesive lines which upon initial opening form the reclosure elements. One piece carton blanks for such cartons are also disclosed.

Abstract: A bag for containing liquid products, for example, is made of a heat-weldable sheet material. The sheet material may suitably be a compound sheet material which provides a rear face, a front face and an insert bottom. Disposed at an upper portion of the front or rear face is a threaded closure comprising a screw-threaded pipe socket and a screw cap. The pipe socket penetrates one face of the bag and is bonded to the interior surface of the bag with the aid of a welding flange having a larger diameter. The welding flange has a chamfered outer rim cooperating with the sheet material to form a V-shaped circumferential groove which is at least partially filled with the molten plastic material of the sheet during the welding operation. The threaded closure permits the bag to be repeatedly opened and closed for piecemeal dispensing its contents.

Abstract: A container for containing a plurality of cigarettes, comprises a front wall panel, a rear wall panel, two side wall panels, and two end walls. One of the end walls, namely the bottom wall, is constituted of a pair of panels slitted and formed with fold lines such that they may be folded against each other to a closed condition to form the respective container end wall, or may be unfolded to an open condition and retained in the open condition to form an extension of the container to serve as an ashtray.

Abstract: A continuous partially preprinted, preglued form suitable for subsequent envelope construction comprises a single web partially preprinted on one side, having detachable marginal feed hole strips parallel with each longitudinal edge, and transverse marginal lines of perforations defining individual envelope forms with two transverse lines of perforations defining fold lines intermediate the marginal lines. On the side of the web opposite the preprinting, a first transverse adhesive strip is disposed immediately adjacent one of the transverse marginal lines and a second transverse adhesive strip is disposed parallel to the first transverse adhesive strip intermediate between that strip and the adjacent fold line. Two first aligned longitudinal adhesive strips lie parallel to one of the longitudinal edges adjacent a marginal feed hole strip with one adhesive strip extending between the transverse adhesive strips and the other extending between the transverse fold lines.

Abstract: A bottom filled, top gusset plastic bag (10, 106) includes a pair of flexible ear handles (24, 26 or 130, 132). The handles include circular hand-receiving openings (76 or 134) and have circular outlines and circular transition regions (78, 80 or 136, 138) are provided between the ear handles (24, 26 or 130, 132) and attached base portions of the handles. The circular hand-receiving openings (76 or 134) and the curved transition regions (78, 80 or 136, 138) function to distribute weight forces substantially across the full width of each side of a filled bag (10, 106).

Abstract: A top cover (22) of flexible thermoplastic material is provided at the upper end of a bottom-loaded plastic bag of a type having a closed top (10) and a "carton" look when filled. The top cover is connected by heat seals (44, 46) to upper peripheral portions of the bag. The top cover is heat sealed to itself at (56), dividing the top cover into a base (22) and a handle (24). The handle (24) includes a hand-receiving opening (76).

Abstract: A carton for an even number of rows of cans has a carrying handle formed from strip-reinforced carton material by means of cuts flanking the reinforcing strip and separating the handle from the rest of the carton, said strip being off-set from the median plane of the carton where it can surround one of said rows of cans.

Abstract: A package for foods is disclosed and comprises a container having a peripheral flange at its mouth. The container is made of or lined with a plastics material so as to provide a plastics surface at the flange. The container is covered by a lid which is heat-sealed to the flange. In order to be able to open the package easily, especially when it is hot, a tear-strip of material extends across at least the flange and is secured to the lid by a heat seal. The tear-strip presents a tab for engagement by the fingers of a user, and, in order to ensure that the lid can be torn effectively by the tear-strip, the bond between the tear-strip and the lid is chosen to be at least as strong as the bond between the lid and the flange.

Abstract: A bag comprised of flaccid material and having an improved integrally formed carrying handle which supports the weight of one or more articles contained within the bag with minimal discomfort to the supporting portion or portions of the user's body. The bag includes an uppermost flap containing the improved integrally formed carrying handle. The handle is provided by making a continuous curvilinear slit in the flap, the ends of the slit comprising a pair of inwardly. open arcs. The uppermost ends of the inwardly open arcs are inwardly extended until they transition into a centrally located, upwardly concave arc which connects the two inwardly open arcs to one another.

Abstract: A microwave ovenable package is disclosed including a top structure which incorporates therein a pair of handle elements useful for removing the package from the microwave oven. In the preferred embodiment, the top structure includes integral side walls which are adhered to the sides of the package. The integral side walls are connected to the top structure along cut/scored lines which delaminate upon opening the top. The portions of the side walls which remain attached to the package can then be folded outwardly to produce handles for removing the package from the microwave oven.
