Abstract: A novel ice cream product container with complementary closure member is disclosed. The container body member is usually of paperboard and formed from an integral blank comprising edge-reinforcing flaps articulated to wall members, which reinforcing flaps are then folded down upon and secured to their respective wall members to provide a reinforced portion of double thickness in the container formed from the blank. This folded-over, reinforced portion is also present in the flat-folded tube produced from the blank, the squared-up tube, the erected container, and finally in the closed and filled package. This folded-over, reinforced portion of double thickness contains defined areas of low resistance adapted to receive lugs formed in a wall of the complementary closure member. The closure member also provides a complementary channel between essentially upstanding and downstanding walls for receiving the reinforced portion of the container walls in frictional engagement therewith.

Abstract: Disclosed is a container for storing product, a process and apparatus for making that container, a process and apparatus for drawing and blow forming plastic into a paperboard outer container and a process and apparatus for heat sealing a container. The container comprises a paperboard outer container and a plastic inner container which has been drawn and blow formed into the outer container. At the mouth of the container are horizontal plastic flanges which extend about the periphery of the container at least about 1/8 inch outwardly from the plastic inner container. Vertical flanges extend downwardly at least about 1/8 inch from the horizontal flanges. After product is placed in the container, the container is sealed by a heat sealable cover. A plastic overcap may be provided which engagedly fits around the container at its top.

Abstract: There is shown apparatus and method for producing a container preferably made or constructed of heat sealable material. Shaping of the container is by forming and not heat stretching or other distortions. In the depicted examples of the container the travelling strip is formed with a midwidth transverse cut leaving on and at each edge a carrier strip. The formed container is preferably filled with a product and then a cover to retain the product is brought to this container and heat sealed in place by the apparatus. After this filling and sealing, the package is further severed at the prior transverse cut to make separate packages.

Abstract: A one-piece blank forms a liquid-tight carton having plural rectangular side walls sealed or integral with one another at adjoining side edges and flat end panels of polygonal shape, the carton facilitating ultrasonic sealing of the end walls to the sidewalls through a unique set of sealing tabs on the side and end walls. The process and equipment for sealing the end walls to the side walls permits ultrasonic heating and sealing after the carton is full of liquid through a compression of the sealing tabs of these walls between facing dies which are diagonally aligned in relationship to the side and end walls. The carton formed by this blank facilitates nesting of multiple cartons, one above the other.

Abstract: Method of manufacturing a filled packaging container comprising the steps of forming a bag on a mandrel, connecting a seam provided in a formed bag, forming a hole on an upper side of the bag and inserting a valve into the hole to provide an air pressure release after filling the container with a material. Two opposite edges of the valve are formed with two flexible portions made of foil. A sealing fluid is applied in the channel to provide a fluid film to connect the foil portions.

Abstract: A method and apparatus for closing and sealing the end of a container having a tubular body wherein the container and closure portion includes front, rear and side panels each extending axially from the tubular body in the open position of the end closure. Each of the end closure panels may have a sealing strip defined at its outer end by a scored line with the rear panel including a closure flap-extending from the outer edge of its sealing strip. The end closure panels are folded to a flat closed position by closing jaws with the sealing strips and closure flap projecting axially from the tubular body, after which the sealing strips are sonically welded together. The closure flap and sealing strips are then folded flat, and the closure flap is welded to the outer surface of the front end closure panel.

Abstract: Disclosed is a thermoplastic container formed from a flattened thermoplastic sleeve that is fabricated at a first manufacturing location. These flattened sleeves are conveniently transported to a second manufacturing location where they can be compactly stored. As containers are needed, the ends of the sleeve are stiffened by forming a flange or bead, thereby providing a tubular central section with a stable cross-sectional shape suitable for the application of conventional end closures.

Abstract: A receptacle is formed from an appropriately scored blank by mechanical folding and set-up prior to its being filled, and for mechanical closure of the self-contained cover members after the filling of the receptacle.

Abstract: Methods of making feminine hygienic pads from non-layered and layered material by use of folding, pressure molding and various methods of bonding to create a long geometric form with an anterior leading panel of narrow thickness and a thicker posterior underpanel of a wider thickness. The folded panels may be bonded by either a suitable adhesive, crimping, heat, pressure or ultrasonic means leaving an anterior portion with a leading anterior edge and a larger posterior portion. A filler may be inserted between the folds of the material prior to bonding. Thereafter, the long geometric form is multiple cut transversely providing pads about two inches long. These pads are used for insertion into the female interlabial space. The geometric configuration of the pads facilitates insertion of the pad via the anterior leading edge into the interlabial space and has improved retention within such space.
