Abstract: 1,024,728. Knock-down containers; pallets; labels. G. H. JOHNSON, and G. T. O'LEARY. Oct. 7, 1963, No. 39448/63. Headings B8F, B8H and B8P. [Also in Division E2] A knock-down container consists of a pallet base, corner posts, sides and a top, the base, walls and top all being releasably secured to the posts by suitable fastening elements (see Division E2). Pallet construction.-The pallet comprises two layers of latticed channel section members 10, Fig. 9, spaced apart by short upright members of which those at the four corners provide sockets 13 for the reception of the comer posts. The load bearing surface may be covered by a " skin " 1 preferably (see Fig. 26) comprising four separate metal plates. The edges may also be covered by metal panels 25, Fig. 1, except for the fork track entering apertures, the edges of which may be cushioned. They may also be fitted with flushmounted projecting lugs 170 (Fig. 25, not shown) to facilitate stacking. Slinging.-The hollow corner posts 3, which fit into the sockets 13 of the pallet and are retained therein by cross pins, each contain a loose lifting link 35, Figs. 14 and 17, and a fixed lug 36 which allows the link to move between the broken line storage position and full line lifting position. Container assembly. - The posts 3 are assembled as described above and the walls are secured to the posts 3 by spring-loaded bolts on the walls fitting into holes in the posts. In Fig. 1 the walls 7 are panels on which the bolts 87 are mounted on the outer face; in Fig. 26 the walls comprise crossed struts 141 whose ends carry blocks each fitted with a key-operated bolt (Fig. 28, not shown). The top is either a panelled lid or a skeleton structure (as in Fig. 26) in each case including sockets which fit over the tops of the posts and are secured thereto by key-operated bolt members 43 as shown on section line 17-17 in Fig. 14.

Title: Actuator Button for Pressurised Aerosol Dispensing Containers
Inventor: LEHMANN HERBERT GIBNER
IPC: B65D83/14
Filed: 1966-09-03
Abstract: 1,162,684. Delivering measured quantities of liquids. AEROSOL INVENTIONS & DEVELOPMENT S.A. 3 Sept., 1966, No. 39488/66. Heading B8N. [Also in Division F1] An actuating button for the discharge valve of a pressurized aerosol dispensing container is adjustable so as to discharge a metered quantity or to discharge continuously. The button comprises a body portion 10 mounted on the discharge valve stem 22, and having a passage 34 acting as the metering chamber, and a discharge passage 38 controlled by a spring-loaded resilient shell member 12. In the metering position of shell member 12 shown, downward movement of member 12 by finger pressure moves a discharge port 48 out of register with passage 38 and then opens the discharge valve to fill passage 34. When the button is released, the discharge valve closes and port 48 registers with passage 38 for discharge of the contents of passage 34. For continuous discharge, member 12 is rotated to align a discharge port 58 with an indicator 40, so that, when member 12 is depressed, port 58 registers with passage 38 and the discharge valve opens. A cutaway 60 in member 12 aligns with indicator 40 to permit sufficient downward movement of member 12 in the continuous-discharge position. Indicator 40 has an arrow indicating the direction of discharge (Fig. 4, not shown). Vertical ribs on the body member 10 engage grooves in member 12 in the metering and continuous discharge positions of member 12. Indicator 40 and the ribs on member 12 serve for holding members 10 and 12 when rotating member 12. In the embodiment of Figs. 9 to 11 (not shown), a part (75) of the resilient side wall of member 12 is biased against member 10 to seal discharge passage 38 when member 12 is in its metering position and the button is depressed to fill the metering chamber, a spring member (80), (78) transmitting finger pressure to part (75). In the embodiment of Figs. 12 and 13 (not shown), sealing of passage 38 during filling of the metering chamber is effected by an inclined portion (92) of member 12 acting on an inclined portion (88) of member 10.
