Filed: 1949-06-30
Abstract: 669,860. Packaging. OHLEF, P. June 30, 1949. No. 17344/49. Class 94(i). The mouth of a filled bag 20, Fig. 1, is closed by the insertion of a closure lamina 30 having a bent-up rim which is subsequently sealed to the rim of the bag mouth. Sealing may be effected by adhesives or heat and/or pressure, e.g. adhesives may be applied to the rim of the lamina during the formation thereof or during the inserting operation, or strips of thermoplastic material may be applied to the rim of the lamina and the two rims pressed together by heated members. The rim on the lamina is preferably formed as it is moved downwardly towards the mouth of the bag, the edges of the shorter and longer sides being folded upwardly in succession and the resulting triangular flaps folded against the shorter sides as indicated in Figs. 8-12a (not shown). Cut-outs and creases may be provided in the lamina to facilitate folding thereof. Apparatus for inserting the closure lamina is shown in Fig. 2 and comprises a ram 44, 47 reciprocable by a connecting rod 43 and hand crank 40 within a frame comprising vertical members 39. The plunger is surrounded by a bush 48 from which two rings 50, 51 are suspended by rods 49, the rings being slidable on the rods and urged against stops 52, 53 by springs 54. When the ram head 47 rises, it engages the undersurface of the bush and moves the rods and rings upwardly and on the return stroke an abutment on the ram 44 entrains the bush and moves the rods downwardly. During this movement, the lower ring 51 is retained by stops on the frame so that the ring 50 is moved relatively thereto against the action of the springs 54 and wedges 57 thereon engage inclined faces on members 60 to effect inward movement of heated pads 62 slidably mounted in the rings 51. In operation, a flat closure lamina is positioned on the top of a folding box 65 and the ram operated to force it through the box, whereby it is formed with a rim as described above. As the ram moves out of the folding box, the lamina is retained on the ram head by aprons 79, see Fig. 4 (not shown), which are slidably and pivotally mounted on the frame and urged inwardly by springs. Further movement of the ram moves the aprons into the bag and rocks them outwardly to spread the bag mouth and just before the insertion of the closure lamina, lugs 85 on the wedges 57 engage levers 86 to return the aprons to their initial positions. The wedges then actuate the pads 62 to heat-seal the rim of the closure lamina to the rim of the bag.
