The invention concerns a solvent-free, polymerizing hotmelt substance free of, or low in monomers, for corrosion- and/or abrasion proofing and/or forming a protective film with barrier properties on a real substrates and molded bodies made of metal, plastic, cellulose materials and/or inorganic materials, in particular for wrapping purposes, and consisting of

Solvent-free, low-monomer or monomer-free polymerizable hot melt

An easy-open package has a vessel forming an upwardly open compartment and having an annular rim surrounding the compartment and a foil engaging the rim of the vessel part all around the compartment, having an open tab which projects laterally past the rim, and formed with a tear line extending around the compartment except at the tab and extending around and delimiting of the tab. The tab is unitarily formed with the foil and is connected to the foil by an integral web that overlies and is bonded to the rim. The bond between the foil and the vessel is substantially weaker at the web than elsewhere.

Easy-open package and method of making same

An easy-open package has a vessel having an annular peripheral rim and at least one crosswise rib forming with the rim a plurality of upwardly open compartments, a foil engaging the generally coplanar upper edges of the rim and rib of the vessel, formed with a tear line extending around the rim, and provided with an open tab attached to the foil within the tear line, and repsective rim and rib hermetic bonds securing the upper edges of the rim and rib to the foil. When the individual compartments are to be kept separate, the foil is formed with an annular tear line around each such compartment and is provided within each tear line with a respective such open tab.

Compartmented easy open package

An easy-open package for a fluent material comprises an upwardly open base vessel having an annular rim, a foil having an outer periphery engaging the rim and formed inward of the periphery with a nonstraight tear line defining a tearout portion, an open tab engaging the portion within the tear line, and respective bonds securing the foil at its periphery to the rim and securing the tab to the portion within the tear line.

Easy-open package for fluent material

An easy-open package comprises a vessel part forming an upwardly open compartment and having an annular rim surrounding the compartment and a foil part adhered to the rim of the vessel part all around the compartment, unitarily formed with an open tab which projects laterally past the rim, and formed with a tear line extending around the compartment except at the tab and extending to an outer periphery of the foil part to each side of the tab. One of the parts is formed as a laminate including a metal layer, a synthetic-resin layer, and a relatively weak bond securing the synthetic-resin layer to the metal layer. The synthetic-resin layer of the one part is bonded to the other part along an annular strip running around the rim with a relatively strong bond and the one part is formed in the synthetic-resin layer with at least one secondary tear line at the tab.

There are described solvent-free, low monomer or monomer-free polymerizable melt compositions suitable for the corrosion and abrasion resistant coatings of substrates and formed bodies of metal, plastic, cellulose materials and/or inorganic materials and/or the creation of a protective film with barrier properties and methods of making them. The melt compositions are particularly useful especially for use in packaging, and comprise: (a) at least one polymerizable, hydroxyl-containing polymer having an average molecular weight (Mw) of between 1,000 and 500,000 and a glass transition temperature (Tg) of .gtoreq.+20.degree. C., and/or (b) at least one polymerizable, linear unbranched and/or branched polyester and/or its copolymer having an average molecular weight (Mw) of between 800 and 50,000 and a glass transition temperature (Tg) of .gtoreq.-50.degree. C., and/or (c) a polymerizable oligomer carrying an ethylenically unsaturated group, of the following group consisting of acrylic, methacrylic, ether, ester, urethane, amide, imide, epoxide, siloxane, phenol, novolak and/or mercapto compounds having an average molecular weight (Mw) of between 400 and 10,000, and (d) if required, conventional additives. Further described are processes for preparing these melt compositions and methods of further processing these melt compositions and finishing planar substrates and/or shaped bodies with these melt compositions. Moreover, the present invention relates to a process for polymerization or curing of the melt composition.

At least one complete surface of at least one metallic part of a can is given a uniform coating of corrosion-preventing lacquer and this part is subsequently worked such that the metal of the part is exposed at regions at least immediately adjacent the coated surface. Dots of lacquer are sprayed by the ink-jet method substantially only on the exposed regions of the part after working thereof and so that the dots together form a continuous layer covering the exposed regions. According to the viscosity of the lacquer the surface coating can be achieved by partially overlapping adjacent dots of the applied lacquer or without overlapping by the running together of the adjacent dots of the liquid, with no excess material having to be applied to and subsequently removed from the regions to be coated.

Method of and system for coating exposed can edges

The apparatus of the invention provides a coat of lacquer or varnish on a tear-off cover, which is formed from a thin ferromagnetic metal, has a circumferential supporting lip and is equipped with a tear-off opening made by scoring and/or punching in or out the cover surface. To provide the coat of lacquer or varnish the cover is moved through an electric coating tank, a washing tank and drying zone with the plane of the cover oriented substantially vertically while being supported exclusively on the surface of the inner wall of the supporting lip. The entire surface of the cover is completely covered by the lacquer or varnish coating except for a small portion on the inner wall of the supporting lip which is positioned inside the closed container in a folded seam and/or covered by a sealing material.

Apparatus for making a lid having a tear-away opening

The holding device for conveying container bodies open at both ends made of ferromagnetic material on a conveyor has at least one permanent magnet for generating magnetic forces necessary to hold the container body on it, a supporting member attachable with the conveyor and two framework components (one of which may be made slidable) held spaced from each other aligned in the longitudinal direction of the supporting member. Alternatively in two specific examples of our invention the permanent magnet is provided in the vicinity of the framework components and the supporting member is insertable in the container body or the permanent magnet is provided on the supporting member or it is the supporting member and an electrode distinct from the supporting member is insertable in the container body. The framework members have a substantially U-shape cross section and are arranged so that their free side pieces on each side thereof parallel the longitudinal direction of the supporting member. Their side piece edges directed away from the supporting member form supporting surfaces for the mounting the opening edges of the container body.

A decor is applied to a tin can by printing a pattern onto a metallic surface thereof directly and hardening the pattern on the metallic surface. The can is then immersion-coated in an electroimmersion lacquering unit to provide it with a lacquer coating. The printed pattern can be an electrically conductive lacquer in order to insure the electroimmersion coating of the printed pattern as well as the exposed metal surfaces which may surround it.

Method of decorating and inhibiting corrosion of metallic articles

A holding device for gripping and retaining containers, including can bodies or cans which have one open end, during transport on conveyers, includes a planar carrier which can be connected at the conveyer chain or forms part thereof. A plurality of clamp elements is secured at the carrier. The clamp elements are made of resilient material, and they are fastened for clamping or snap-like retention of the container bodies at diametrically opposite locations respectively in pairs at the carrier. The clamp elements of each pair have respectively crossing adjacent sections, and the inner clamp is adapted to operatively contact the peripheral edge of the respective retained container. The outer clamp is adapted to operatively engage the outer wall surface of the container rim which is directed towards the carrier.
