| 101 | Tray-type cartons erecting method and apparatus | US589084 | 1984-01-04 | US4626234A | 1986-12-02 | Bernard H. Oxborrow |
| A rectangular tray-type carton formed from a blank of plastics-coated board has a peripheral flange for attachment of a closure lid. The flange is formed after the erection of the carton side wall in a punch and die arrangement, by folding down elongate panels carried along the free edges of the side wall and by subsequently joining the panels together at their ends by means of overlapping tabs which are heat-sealed together. In order to avoid damage to the tabs during formation of the side wall the uppermost tabs are folded out of the plane of the blank before it enters the punch and die arrangement. | ||||||
| 102 | Method of making corrugated packages | US197363 | 1980-10-15 | US4395253A | 1983-07-26 | James A. Goodman |
| A machine for forming a corrugated package from sheet material including a rotatable corrugation head having a fluted periphery and a front face; corrugating means and sealing means movable into association with the head for corrugating an inner sheet material and sealing two plys of material together, respectively; means for feeding an inner sheet having a selected length and width to the head adjacent said corrugating means and means for feeding an outer sheet having a selected length and width to the head adjacent the sealing means; means for moving a bottom wall member having a selected shape into engagement with the front face of the head and associated with the first and second sheets to form the bottom wall of the package; and means to control the operation of said machine so that the rotation of said head and the function of the above-described components are coordinated to form a corrugated side wall of the package from two sheets simultaneously with the joinder of said side wall with the bottom wall member. The method of forming a corrugated package pursuant to this invention comprises the steps of corrugating an inner sheet of material having a selected width and length into fluted corrugations while forming the sheet into a shape defining a portion of the package side wall; positioning a bottom wall member having an outer edge adjacent the corrugated inner sheet; wrapping an outer sheet of material having a width greater than the width of the inner sheet around the corrugated inner sheet so that a portion of the outer sheet projects over the outer edge of the bottom wall member and; simultaneously joining the outer sheet to the inner sheet and to said bottom wall member so that said sheets form plys of a corrugated side wall and are joined to said bottom wall member to produce a corrugated package. | ||||||
| 103 | Method for preparation of cylindrical corrugated article | US747375 | 1976-12-03 | US4080880A | 1978-03-28 | Yukihiro Shikaya |
| A method of preparing a cylindrical corrugated article, comprising supplying a sheet material in between a pair of rotatable forming rolls having interlocking corrugated surfaces thereby to press and corrugate said sheet material, mounting the resulting corrugated article on the rounded surface of one of said forming rolls by means of a guide member, and then discharging the thus mounted cylindrical corrugated article from said forming roll. | ||||||
| 104 | Tray-like container and a method of and an apparatus for manufacturing the container | US624056 | 1975-10-20 | US4057380A | 1977-11-08 | Masaya Hosoe |
| A tray-like container of a plastic coated paper blank having a base panel, which has four or more even numbers of side edges, side walls, corner portions, a peripheral portion extending along side walls and corner portions, and a pig-tail like folding line formed in each corner portion of the peripheral portion, of which a flange of the tray-like container is formed. The pig-tail like folding line assists in the outward bending of the peripheral portion so that it forms the outwardly projecting flange of the tray-like container. The outer shape of the tray-like container is forcedly molded by a movable and stationary complementary moulds. | ||||||
