In Switzerland October 23,. 1948 This invention relates to a closure device for containers, such as bottles, tubes, cans and the 6 Claims. (Cl. 220141)v` top of the container running parallel to the plane of the mouth of the container, the lower longitudinal faces of which bead form guides for a sliding member, which, in the closed position, at least partially covers a closure member and co-operates with the latter in such a way that, on first withdrawing the sliding member, a projection of the latter runs on'to a ramp on the closure member, whereby the latter is tipped into a released position, on further withdrawal the closure member is carried along with it and,

riding up a ramp provided for the purpose on.

the container, is lifted clear of the mouth of the container from the released position, and on still further withdrawal of the sliding member is nally withdrawn from above the mouth of the container.

The bead on the top of the container may be of rectangular cross section.

An annular bead may be arranged around the mouth of the container, having a coned outer surface of erect frustro-conical shape. A ramp may also be provided at the top of the container.`

Gn withdrawing the sliding member one side of the closure'member then runs up the said coned surface and the other side of the closure member runs up the said ramp wherebythe clos-ure member is lifted clear of the mouth of the container. One embodiment of the invention will now be described with reference to the accompanying drawings, in which:

Fig. 1 is a side elevation partly in section showing thetop of the container with the closure device in the closed position, Fig. 2 is a similar view to that of Fig.. 1 ing the closure device open.

Fig. 3 is a plan view of Fig. 1, l Fig. 4 is a section taken through the top of the container on the line IV'-IV of Fig. 1, and Fig. 5 is a section on the line V-V of Fig. l. Referring now to the drawings, l indicates the top of a container provided with a.bead 2 of rec,- tangular cross section running parallel tothe plane I-I of the mouth of the container. The pouring opening is shown at 3; it is surrounded by an annular bead 0, the outer surface of which is of erect frustro-conical shape. A ramp 5 and a travel-limiting stop 5 are also provided on the top of the container. I indicates a sliding member having two guide flanges 8.engaging beneath showing member is provided with anebutment edge la and, in'the closed position of the closure device, atleast partially covers a closure member 9,- which is formed in the shape of a lid with vdownturned margins. An elastic packing l0, for example a cork cushion, is disposed within the lid of the closure member and may be clad with a covering metal foil. 'Ihe closure member is provided with two rearwardly projecting side members Il carryingl ramps 9a for releasing the closure member and also a stop 9b for limiting the stroke of the sliding member.

The manner of operation of the above described device is as follows:

When the closure device is closed (Figs. 1,- 3, 4 and 5) the closure member is seated on the bead 4 of the mouth of the container. The sliding member 'l partially covers the lid of the closure member and presses the elastic packing I0 against the annular bead 4 provided on the top of the container. When the sliding member ,l is pulled backwards, the edge 'lb runs on to the ramp 9a of the closure member 9. As the edge lb runs up the ramp the closure member is tipped as .shown by the arrow A and thereby released. On further withdrawal of the sliding member the edge 'lb engages the stop 9b on the closure member'so that the latter is carried along rearwards with-the sliding member. The front edge of the lid f the closure *member now slides over the adjacent coned face of the bead 4 and the rear4 side slides over the ramp 5 whereby the closure member is lifted clear of the pouring opening. When the sliding member-which may v be roughened or grooved on its outer side to forma hand gripisnow withdrawn further, lthe closure member gradually moves into thev position"'shown in Fig. 2A in' which it abuts the stop 6 on the top of the container. In this position the pouring opening is free for use.

When the device is closed the edge la of the l sliding member pushes the closure member in front of it until the latter is positioned above the pouring opening. When further pressure is applied to the sliding member to close it, the slidingmember* engages over the lid of the closure member along the curve 9c and presses down the the longitudinal faces. of the bead 2. The slidelastic packing I0 on to the annular bead d onthe top of the container.
