Abstract: 1,184,481. Vacuum-formed package machine. MAHAFFY & HARDER ENG. CO. 9 Feb., 1967 [9 Feb., 1966], No. 3997/67. Heading B8C. A packaging machine includes means for carrying cup-shaped containers having flanges around their mouths, the means being arranged for motion around a closed path; means for applying packaging material to the mouths of the containers to make complete packages; a package finishing station which includes a sealing die into which a container fits and a cooperating heat-sealing head to produce a permanent seal line around the mouth of the container; evacuation means to remove air from the package through an opening in the latter lying inside the seal line while it is still within the sealing die; and means to seal off the evacuation opening by sealing the container and packaging material, the package still being within the die. As described, Fig. 2, a web 30 is carried at its edges by clips 36 mounted on parallel chains 26, and to produce packages of different widths the separation of the chains can be varied by crank means, Fig. 14 (not shown). The chains move intermittently to carry the web 30 to a pocketforming station 50 comprising oppositely reciprocable members 52, 54, Fig. 7. The web is first sucked up against a heating plate 74, and the next indexing movement of the chains carries the heated portion 30a to a vacuumforming die 76, where a deep pocket 100 is formed. The die 76 carries a slitting knife 108 which makes a slit 112 in the trailing margin of the preceding cup. At a further location on the path of travel a conveyer 116 deposits a product 118 into the pocket, and from thence the filled container is conveyed to a finishing station 124, see also Fig. 8, comprising two oppositely reciprocable members 126, 128. The member 126 includes a sealing die 146 defining a cavity 148 to receive the filled container 100. The upper member 128 includes a sealing clamp 150 by which a web 122 is heat-sealed to the flange of the container 100. Air is extracted through slit 112 by a passage 154, while a serrated knife 168 severs the package 100 A from its predecessor 100 P. A small amount of inert gas may be introduced into the package by a conduit 156. A pressure bar 176 now rises to force the part of the flange surrounding the slit 112 against the top web 122 and a recessed portion 178 of the hot clamp 150, see also Figs. 9A, 10A, 11A (not shown), to form a seal 180. The vacuum passage 154 is now vented to atmosphere. To produce packages of different sizes, the opposite mating members 52, 54 are readily removable and movable longitudinally to provide for an integral number of indexing movements; the die 146 is similarly removable, leaving the evacuating and gassing conduits intact. The length of each indexing stroke is capable of variation by altering the number of teeth of a Geneva gear which drives sprocket 22. The packages are delivered singly by a shoot 130. Divisional Specification 1,184,483 is referred to.

Abstract: 1,022,379. Stoppers. N. NEUNER. Jan. 29, 1965, No. 4124/65. Heading B8T. A bottle cap 3 with a threaded skirt 1 and a centrally positioned orifice 5, has secured within the cap a resilient disc 6 comprising a skirt 11 and a central boss 8 which closes a bottle neck opening 2, holes 9 surrounding the boss forming a passageway through the disc to the outlet orifice. All the parts of the bottle and closure device are made of a synthetic plastics such as polyethylene. The disc 6, which has an inwardly extending annular flange 12 with a chamfered leading face, is screwed or fixed by a snap ring construction into the cap 3. The boss 8 may engage directly with the bottle neck 2 but as shown, when the cap 3 is first screwed down on the neck 2, the flange 12 snaps into an annular groove formed in a ring portion 4 of a cylindrical insert 10. The flange 12 then slides down in the groove until its lower edge abuts against the upper edge of the groove and the boss 8 is firmly seated on the ring 4, thereby sealing the opening 7. At the same time, a conical plug 14 mounted on the disc 6 is pushed upwardly and closes the orifice 5. On unscrewing the cap 3 through an angle of about 90 to 180 degrees the upper edge of the flange 12 abuts against the lower edge of an annular flange 13 formed on the ring 4. This contact between the two flanges 12, 13 pulls the plug 14 from the orifice 5, thereby enabling liquid to pass from the bottle through the holes 9 and out of the orifice. The abutting flanges 12, 13 also form a seal to prevent seepage of the contents through the threads 1.
