Abstract: A polymer composition and articles fabricated therefrom is disclosed wherein the polymer composition comprises a low density polyethylene resin containing very small amounts of erucamide and oleamide. The composition is useful for forming article carriers and particularly useful for forming carriers for groups of metal cans which cans are subject to rotation in the carrier during use without significant injury to the carrier.

Abstract: A bottle carrier for carrying a plurality of bottles having a body portion and a neck portion and a closure which is crimped around the neck of the bottle and forms a concave fillet at the juncture with the container comprising a generally flat blank formed of a material that is flexible and elastic and has a central portion with a plurality of openings for receiving the neck of the containers and engaging the containers at the juncture of the closure fillet and the container. The carrier also includes a peripheral band that is severable from the first part and moved about the periphery of the bottles. Each opening has a configuration of a substantially isometric 36.degree. ellipse, the ratio of the length of major axis to the length of the minor axis being between 0.5 and 0.65, and the ratio of the perimeter of the greatest side wall dimension of the closure to the perimeter of the opening ranging between 1.25 and 1.40.

Abstract: A bottle carrier for carrying a plurality of bottles having a body portion and a neck portion and a closure applied to the neck portion forming an undercut at the area of juncture of the periphery of the closure and the neck comprising a generally flat blank formed of a material that is flexible and elastic and has a central portion with a plurality of openings and a peripheral band severable from the central portion and adapted to surround the bottles. Each opening is shaped so that only a portion of the periphery of the openings engages the area of juncture of the closure and bottle and a pair of tabs extend radially inwardly for engaging under the closure.

Abstract: A bottle carrier for carrying a plurality of bottles having a body portion and a neck portion and a closure which is attached to the neck of the bottle which comprises a generally flat blank formed of a material that is flexible and elastic. The blank comprises a first part defining a central portion and a second part defining a band which is severable from the first part and is adapted to be stretched about a group of bottles. The first part comprises a plurality of openings in spaced rows for receiving the necks of the containers and engaging the necks below the closures. In order to meet the requirements of adequately securing the bottles in the carrier and at the same time, being able to apply the carrier to the bottles rapidly by automatic machines, the carrier includes the following relationships: (1) minimum widths of the webs between the openings for receiving the necks of the bottles and the periphery of the carrier, (2) the stress on the webs must be less than 550 p.s.i.

Abstract: The disclosure relates to an improved seal bar used with a mandrel-turret machine for winding a sheet blank of heat shrinkable plastic in end overlapping relationship and sealing the overlapped ends by heat and pressure as a side seam of a sleeve. The seal bar includes plural rows of islands disposed along the heated nose surface through its length, the islands consisting of either raised portions or indented portions. The islands interrupt the heated sealing surface providing a series of hot and relatively colder spots. This prevents burning failures in the seam and permits a wider latitude of operating temperatures for the sealing mechanism.There is also a new and novel seamed sleeve of heat shrinkable polymer of the foamed or foam/film type, the seam having corresponding islands appearing as outer surface variations along the seal-seam area corresponding with the placement of the islands on the seal bar nose surface used in making the seam.

Abstract: There is disclosed herein improved packages, and methods of forming same, of the type wherein a container, such as for example a glass container, like a bottle or jar, is provided externally thereof with a heat shrunk, cellular thermoplastic member, circumferentially and snugly engaging a sidewall portion of the container; the improvement resides in employing as the thermoplastic member a composite structure, or laminate, of a closed cellular polymeric layer in which the polymer is a polymer of predominantly olefin moieties and, in adhered relationship to the closed cellular layer, a non-cellular polymeric layer n which the polymer is a polymer of predominantly olefin moieties with the cellular layer being in snug, heat shrunk engagement with the sidewall portion of the container and the non-cellular layer being disposed outwardly of the cellular layer.

Abstract: A method for powder coating of articles with an organic polymeric material. Articles to be coated, preferably glass containers, are transported by a first conveying mechanism through a pre-heat oven wherein their temperature is raised to a level above ambient temperature. The preheated containers are then transferred to chucks of a second conveying mechanism which carry the containers through a powder spray apparatus wherein the organic polymeric material is applied to the container. The chucks of the second conveying mechanism are cool and any oversprayed material will not adhere thereto. After spraying, the containers are again heated to cure the sprayed-on powder coating to form a filmlike layer on the container. The containers are then cooled below the softening point of the organic polymeric material and released from the second conveying mechanism for further handling.
