QLOSURE DEVICE FOR TUBES AND OTHER CONTAINERSl Filed Dec. 12, 1936 A F/G./. /a-
QL i n' Jl J INvENToR KARL RUETZ 'BY @W9/@MMV ATTORNEY S Patented Mar. 15, 1938 CLOSURE DEVICE FOR TUBES AND OTHER CONTAINERS Karl Ruetz, Zurich, Switzerland Application December 12, 1936, Serial No. 115,625 In Switzerland December 17, 1935 2 Claims.
The present invention relates to a sliding closure device for tubes and other containers, such device being characterized in that between the outlet aperture of the container and the slide to be actuated there is arranged awedge member, the lower side of which is provided with a packing plate yand which participates in the movement of the slide over at least a part of its path, `in such manner that on the opening movement of tlie slide the wedge pressure on the edge of the opening is first of all removed, and then the wedge member with the packing plate is displaced by the slide for the purpose of exposing the opening in order that the packing plate may be protected against damage and undue wear.
The annexed drawing illustrates diagrammatically one form of construction of the invention.
Fig. 1 is a vertical section with the slide closed.
Fig. 2 is a vertical section with the slide open.
Fig. 3 is a section along the line A-B of Fig. 1.
Fig. 4 is a plan of the slide.
From the surface I of a cylindrical tube 2 rises a nozzle 3 having an opening 4 for the evacuation of the contents of the tube. On'the polished surface 5 of the nozzle 3 of the tube there is disposed, so as to be displaceable in the same direction as a slide II, a packing plate 6 formed, for instance, of cork which is fixed on 30 the inner side of a wedge member 1. The latter has lateral downwardly-projecting iianges 8 which engage loosely in gaps 9 between the nozzle 3 and the side flanges Ill of the slide I I. The side flanges I0 are guided with inwardly bent 35 guide bars I2 between the surface I of the tube 2 and ribs I3 provided on both sides of the nozzle 3. The wedge member 'I is provided with an upwardly directed projection I4 which engages with lateral friction in a recess I8 in the 40 slide II. At the front of the slide II, under the recess I8, is a conical surface I9 which is inclined in the same manner as the oppositely inclined surface of the Wedge member 1, and at the rear end has a gripping bar 2l) for facilitating the actuation of the slide.
When the slide is in the closed position, as
shown in Fig. l, the packing plate 6 is pressed by the wedge member l firmly against the edge of the opening Il.
If the slide II is thrust into the position shown in Fig. 2, that is to say in the open position, then after the initial idle movement it carries with it the projection I4 and therefore the wedge member 'l until the flanges 8 of the wedge member are held firmly on the vertical end walls of the gaps 9.
At the beas the movement of the slide.
The slide II may be made of metal or of artiiicialV material.
Having thus described the nature of the said invention and the best means I know of carrying the same into practical effect, I claimz- 1. A sliding closure device for tubes and other containers embodying a slide to be actuated, characterized in that between the outlet opening of the container and the slide there is arranged a wedge member provided on its lower side with a packing plate, which wedge member participates in the movement of the slide over at least a part of its path, in such manner that on the initial movement of the slide, the wedge pressure on the edge of the opening is first of all removed, and then the wedge member with the packing plate is displaced by the slide for the purpose of eX- posing the opening in order that the packing plate may be protected against damage and undue wear.
2. A sliding closuie device according to claim 1, characterized in that the container carrying the closure device has a nozzle which is provided with lateral ribs and the wedge member engages by means of a projection in the slide which is guided by said lateral ribs.
