A method and apparatus for removably securing flexible packages to a display carrier strip so that the packages can be removed therefrom without damaging the sealed condition of the packages. The apparatus includes sealing jaws which form transverse seals on a package preform that is separated into two packages. The sealing jaws have attached to the underside thereof sealing blocks which carry sealing elements that heat-seal the display carrier strip to the top of each filled sealed package simultaneously with the forming of the transverse seals by the sealing jaws. The attachment of the packages to the carrier strip is greatly simplified compared with prior art attachment systems.

A rigid body in the form of a truncated cone is dimensioned to fit over the top of a container, such as a can with a beaded top, to allow the opening in a carrier comprised of stretchable or elastic material to be manually expanded by movement of the carrier down the side of the truncated cone, beyond the bottom of the truncated cone, allowing the opening to retract against the body of the container below the beaded top.

A method for the production of flexible pouches each possessing a sealed product-containing pocket and incorporating an integral collar-shaped structure located externally of the pocket to enable suspending of the pouch from a support. More specifically, the method contemplates the sequential in-line production or manufacture of such flexible pouches which are essentially constituted from a sealable, flexible packaging material and which may consist of either a single-layer film material or of a multi-layered laminate so as to enable the containment in the pouches of the most varied types of products possessing widely different properties. In addition to the foregoing, also disclosed is a flexible pouch having a sealed product-containing pocket and incorporating an integral collar-shaped structure which is produced by the inventive method.

A method of attaching a gripping device to a packaging laminate involves forming a recess in a packaging laminate that extends only a part of the way through the thickness of the packaging laminate. Molten plastic material is injected into the recess to cause the molten plastic material to become partly united with plastic layers that cover the central carrier layer of the laminate, thereby forming an anchorage device in the laminate. The gripping device can be attached to the anchorage device after the injection molding process or simultaneously during the injection molding process.

A suspension pack for supporting articles in point-of-sale advertising. The suspension pack includes a body folded to provide wall portions in face-to-face contact, and a suspension member extending through a slit in the fold. A base portion of the suspension member has at least one resilient tongue which engages the fold to resist withdrawal of the suspension member from the body.

A bag covering apparatus that puts a cover, which has been folded in two at the folding portion, on the opening of a bag. The same bag covering apparatus includes a folding piece which can operate to fold the cover in two at the folding portion and a cover retaining piece provided near the folding piece, having at least two holding portions capable of holding the folding portion of the cover. The folding portion of the cover is inserted into the holding portion of the cover retaining piece by the action of the folding piece, the cover retaining piece being movable such that when one of the holding pieces of the cover retaining piece faces the opening of the bag, the other holding piece of the cover retaining piece faces the folding piece. A linking piece is operationally linked to the cover retaining piece, making the opening of the bag and the holding portion of the cover retaining piece facing the opening of the bag approach each other by the action of the folding piece, positioning the cover on the opening of the bag.

A length of tape 3 is bonded to a heat shrinkable film 2, and the film 2 is weakened along the edges of a central portion of the length of tape 3. The film 2 is then wrapped around an article or articles, has its two opposite ends sealed together, and is heat shrunk around the article or articles causing access openings 6, 7 in the sheet in the weakened areas along the central portion of the tape that can then be used as a handle for the resultant package 1.

A handle adhering device wherein an adhesive is applied to one surface of a belt-like article, auxiliary pieces are adhered to the adhesive surface with predetermined spaces therebetween, the belt-like article is wound onto a reel-like shape, is cut into predetermined lengths to form a handle member in which adhesive surfaces are exposed at both ends, and the adhesive surfaces of the handle member are adhered to both side surfaces of an article. In this device the non-adhesive surface of the belt-like members are sucked onto an outer peripheral surface of a rotating drum and are paid out by predetermined lengths respectively, cut by a cutter as the drum rotates to form the handle members and lifted off of the rotation drum by adhesive arms passing through recesses in the drum to adhere the adhesive surfaces at both ends of the handle member.

A method for positioning handles on a sachet-type container made from a flexible synthetic material comprises attaching handles to a sleeve of synthetic material while the sleeve is on the mandrel. The sleeves are cut and flap-like corner portions are folded over onto the handles. The handles may be fed from a magazine.

The invention describes a machine which folds blanks of cut and creased material to define folded tabs which have tongues. The tongues have flaps which are folded over onto the tongues and the thus held tabs are transported by a revolving drum and the tongues and flaps are inserted in an aperture or apertures of a holding device holding groups of containers together. The machine operates continuously and the drum is provided with pairs of plates the opening and closing of which are controlled by cams to enable the insertion of the folded blanks within the pairs of plates by an insertion knife which reciprocates radially of the drum.
