Description

July 30, 1963 K. RuE'rz CONTAINER WITH CLOSING DEVICE E Filed Nov. 28. 1960 INVENTOR.
K A R L R U E TZ www@ WWWRWNWWVVUW/ /ZMU ATTORNEK United States Patent Gice 3,099,361 Patented July 30, 1963 3,099,361 CONTAINER WITH CLOSING DEVICE Karl Rnetz, Bergstrasse 132, Zurich 7/ 32, Canton 'of Zurich, Switzerland Filed Nov. 28, 1960, Ser. No. 72,039 Claims priority, application Switzerland Nov. 28, 1959 4 Claims. (Cl. 21S-'73) The present invention relates to a container with closing device.
According to the invention, the container has a branch surrounding a pouring opening and having a torus on the free end directed radially outwards, yand the closing device has a socket with a groove on its inner side for taking the torus, as well as two annular surfaces which are sepa-rated from each other by a depression, surround the outer side of the socket above and below the groove, and 'lie flexibly sealing on the inner wall of a closing cap that can be pushed over the socket.
'In lorder to secure the closing cap on the socket in such a closing device, the closing cap can be provided with an inwardly-directed hollow prolongation surrounded by a torus, which lies behind the lower edge or in a groove in a branch insertable into the pouring opening of the container, and the lower or the upper edge of lthe socket is provided with axiallydirected, arcuate depressions, in which lie axially-directed, arcuate projections on :the lower edge for on 4an inner shoulder of the closing cap.
Three examples of execution of the container with closing device according to the invention are shown in the accompanying drawing, in which:
FIG. 1 shows the iirst example of execution in an axial section through the pouring branch of the container and the closing device placed thereon,
FIG. 2 a view looking down on FIG. 1 with the closing cap removed,
FIG. 3 an axial section of the second example, and
FIG. 4 an axi-al section of Athe third example of execution.
The pouring branch 1 of the container illustrated in FlGS. l and 2, consisting in the present case of a glass bottle, has a torus 2 directed outwards and surrounding the pouring vopening of the branch 1 at its -free end.
The closing device consists of a socket 3 of elastically mouldable material, for instance soft plastics, with a groove 4 on its inner side for taking Ithe torus 2` on the branch 1, which are constructed iitting tight on each other.
Above and below the torus, the socket 3 has on its outer side annular surfaces 5, surrounding t-he socket and separated from each other yby a depression `ti. Onto these annular -surfaces 5 a closing cap 7 is pushed, which consists of a material harder than the socket 3, for instance hard plastics, Bakelite or metal. The inner wall rests sealing on the annular surfaces 5, whereby lthe socket 3 is pressed with its groove 4 resiliently onto the torus 2 and at the same time lalso the annular surfaces 5 onto the inner wall of the closing cap 7.
Running parallel to itself, the socket 3 carries a wall 8 by means of which it rests sealing on the inner wall of the po-uring branch 1 of the container, and a collar 9 directed upwards which 'with the lateral opening 10 forms a pouring outlet, thus allowing the contents of the container to flow back again out `of the annular space between socket and collar 9l when the container is set upright after the pouring.
The collar 9 might be omitted, the sharpened upper edge of the socket 3 being then used as pouring outlet.
According to Ithe drawing, the peripheral wall of the closing cap 7 is tapered; it could, however, also be cylindrical.
The closing device, consisting of the socket 3 and closing cap, may be slipped as a wholei.e. with the closin-g cap 7 pushed onto the annular lsurfaces 5onto the branch 1 of the container, whereby the tor-us 2 springs into the groove 4 and thus connects the socket 3 -to the branch 1 of the container. For opening .the closure of the container, only Ithe closing cap 7 can be withdrawn from the socket 3 and/ or its annular surfaces '5. When the cap 7 is pushed onto the annular surface-S, the container is again closed tight. The elastic material of the socket 3 allows resilient yielding of the wall parts of the socket with the annular surfaces 5 and causes the latter to lie sealing on the inner side of the cap 7, thus always giving tight closure.
The pouring branch 1|1 of the container illustrated in FlG. 3, consisting in the present case `of a glass bottle, has a torus 12 directed outwards and surrounding the pouring opening of the branch 11 at its free end.
The closing device consists of a socket 13 of elastically mouldable material, for instance soft plastics, with a groove 14 on its inner lside for taking the torus 12 on the branch 11, which are constructed fitte-d tight on each other.
Above and below the torus, the socket 1'3 has on its outer side annular surfaces 15, surrounding the socket and sepa-rated from each other by a depression 16. Onto these annular surfaces 15 a closing cap 17 is pushed, which consists of a material harder than the socket 13, for instance hard plastics, Bakel-ite or metal. The inner wall rests sealing on the annular surfaces 15, whereby the socket 13 is pressed with its groove 14 resiliently onto the torus 12 and at the same time also the annular surfaces l15 onto the inner :wall of the closing cap 17.
Running parallel to itself, the socket 13 carries a wall 13 by means `of which it rests ysealing on the inner wall of the pouring branch 11 of the container, and a collar 19 that forms a pouring outlet.
The closing cap 17 carries a hollow, inwardly directed extension 2li with a torus 21 at its lower end. This torus 21 Ilies under the lower end of the wall 18 and thus secures the cap 17 against unintentional loosening from the s-ocket 13.
The torus could also lie in a groove in the Wall 18, whereby the extension 20 is kept correspondingly shorter, or the torus could be arranged above the lower end of this extension 20.
For withdrawing the closing cap 17 from the socket 13-an operation rendered more difficult by this toruson the lower, radially widened edge of the socket 18 as shown in FIG. 3 axially-directed, arcuate projections 22 are provided, wh-ich lie in axially directed, arcuate depressions 23 at the lower edge of the closing cap.
When the closing cap 17 is turned as is usually done when loosening a `closing cap, the lower edge of the closing cap 17 runs up between the depressions 23 `onto the projections 22, whereby the closing cap is axially displaced. Thus the torus 21 is brought out of engagement with the lower edge of the extension 201 or with the groove in its Wall, so that the closing cap 17 can easily be withdrawn from the socket 13.
In .the case of the example of execution shown in FIG. 4, in which the same parts as in FIG. 3 are given the same reference numbers, on the inner side of the capy 17 there is a yshoulder 24, in which the axially directed depressions 23 are provided. '[he axially directed projections 22 are then arranged at the upper edge of the socket 13.
