The invention relates to a trayless close packed array of cans locked together in a heat shrunk sleeve. The packaging machine includes a marshalling station for marshalling the cans in arrays in which there are unequal numbers of cans in each row and a collation station in which the array of cans in rows and columns are collated into close packed formation. A wrapping machine wraps a plastic sleeve around the close packed array and a sealing station seals and heat shrinks the sleeve around the a...

A packaging box is formed by a bottom surface member disposed at the side of a bottom surface of goods to be packaged, and a top surface member disposed at the side of a top surface of the goods to be packaged. The bottom surface member includes a base panel, side panels formed extending integrally from the base panel and further shaped to correspond to side surfaces of the goods to be packaged. An attachment panel extends integrally from the end of each side panel. The top surface member and ba...

The invention provide an apparatus that can seal with film an article placed on a tray without having to change tooling for each shape and size of tray. Packaging apparatus 1 covers opening o with film Fm and thermally welds film Fm to flange f. Tray T is provided with flange f and opening o surrounded by flange f on its upper face. The apparatus is provided with roller 3 and roller swivel mechanism 8. Roller 3 can touch against film Fm on a portion of flange f. The touched surface of roller 3 i...

A product is placed in an inner package, which in turn is placed into outer package. The inner and outer packages have overlying transparent or cut-out or window portions overlying the product or portions of the product enabling the product to be viewed without opening or dismantling of the package assembly. Similarly an information sheet is placed in the outer package below the transparent or cut-out or window portion of the outer package enabling the information sheet to be read without openin...

A method of making a package having contents comprising the steps of taking a tube of flexible material having a top and a bottom end, ultrasonically sealing a bottom band seal across the tube, inserting the contents into the tube, and ultrasonically sealing an upper band seal across the tube at a location spaced away from the bottom end of the tube, with the contents contained between the upper and bottom band seals.

A packaging device for sealingly closing an upper foil and a lower foil utilizing a framelike constructed welding device which has a separate drive for welding together the lower and the upper foil, of which at least the lower foil is formed into containerlike segments and is moved, held by a chain at the sides thereof, through the packaging device. The packaging device has an evacuating chamber which is formed of two boxlike halves, of which one half is stationary and the other half is vertical...

Skin packaging material comprising a film of thermoplastic material having a reinforcement consisting of strands (in the form of netting, or all extending in one direction parallel to one another) adapted on exposure for an appropriate time interval to a source of heat to have both the film and strands heat up to a forming temperature for being skin packaged around an article on a substrate, with the strands less extensible than the film on equal heating of the film and strands, and the skin pac...

From a row of objects which are conveyed on an intermittently movable feeding conveyor, every second object is deposited on lines of wrapping materials at a first station, which lines are advanced continuously under the feeding conveyor, and the remaining objects are deposited on the same lines of wrapping materials at a following station. In connection with one or both depositing steps, the objects are shifted transversely of the direction in which said lines are advanced. Thus, the number of l...

A packaging unit has a container closed by a safety plug which has a maximum diameter equal to the outer diameter of the container opening and a smooth exterior to avoid any gripping surface. A cylindrical lip adjacent to the peripheral edge of the plug cooperates with the inner surface of the container opening to seal the opening. A slide is movable along a radial direction of the plug to extend beyond the edge of the container opening to provide a gripping surface for removing the plug. Safety...
