Description
AP 1954 o. H. RASCH CLOSING DEVICE FOR BOTTLES Filed May 18, 1949 Patented Apr. 6, 1954 CLOSING DEVICE FOR BOTTLES Orla Hanson Rasch, Frederiksberg, near Copenhagen, Denmark Application May 18, 1949, Serial No. 93,889
Claims priority, application Denmark May 20, 1948 3 Claims.
The present invention relates to closing devices for bottles.
Great efficiency is required of bottle stoppers which have to be removed and replaced several times, especially stoppers for medicine bottles and the stoppers hitherto produced for such bottles have therefore not been quite satisfactory.
Such closing devices must be perfectly tight, so that the stopper can be used also in cases in which the pressure inside the bottle is greater than that of the surrounding atmosphere.
With regard to hygiene the edge of the bottle mouth must be covered so that it will not during long storage be infected with dust.
Besides, the stopper must be capable of being put into place easily and rapidly, and all these requirements must be fulfilled both when the stopper is put into place after the first filling of the bottle and in the course of its future use.
A perfect closing device must further be adapted for use in combination with bottles having a pouring lip facilitating the pouring out of the contents and preventing the contents from running down the side of the bottle.
It is the main object of this invention to provide a closing device with a neat and smooth appearance; which is easily inserted and removed; which gives perfect security against the accumulation of substances likely to cause infection; and which allows the use of bottles with outwardly directed pouring li s or pouring spouts.
An embodiment of the closing device according to the invention is by way of example shown on the drawing in which Fig. 1 shows a closing device in side elevation,
Fig. 2 shows the device of Fig. 1 in axial cross section and Fig. 3 a plan view.
The bottle i is provided with threaded projections 2, by means of which a bottle cap may be held as described in the following, and with a mouth formed in the shape of a pouring lip 3.
The closing device consists of a cap 4 made of rigid material, for instance, metal or plastic, the bottom of which is provided with a central hole into which a resilient cork or stopper 5 is inserted. In the embodiment shown the cap 4 is provided with projections in the form of pressed tongues 6 which, when the cap is put into place, mesh with the projections 2, thereby pressing the cap downwards, but it may, as an alternative, be provided with internal threads fitted to the threads on the bottle-neck. The
cork 5 is inserted in a cover I of smooth and rigid material. This cover is provided with salient parts 8, 9, which cannot be carried through the central hole in the bottom of cap 4. The cap 1 fits loosely into said hole, so that cap 4 and the cork 5 may turn freely in relation to one another. When the cap 4 is being screwed on the bottle, the bottom of the cap will press against the salient part 8, and force the cork down into the mouth of the bottle closing it tightly and securely. As will appear from the drawing the cap does not contact the pouring lip 3. The shape of this lip is therefore of no importance with regard to the tightness of the closing. The pouring lip 3 may therefore be hardened so as to be able to resist the normal strains to which the bottle is exposed in use and during cleaning. The cap 4 serves to protest the entire mouth of the bottle, so that it will always be kept free from dust even if the bottle after having been opened is allowed to stand for a long time. The pouring lip 3 may be formed in such a way as to prevent drops of the contents from running down the side of the bottle during pouring. The projections 2 may advantageously be formed in such a way that they do not present deep or sharp corners in which congealed contents may deposit in such a way as to make it difi'icult to remove them when the bottle is being cleaned.
Outwardly the closing device is of quite smooth appearance and as will appear from Fig. 2 it will give the bottle a decorative look which will not be changed by repeated use.
The present closing device ensures tight closing even if the pressure within the bottle is considerably greater than the outside or atmospheric pressure, a feature which is of importance in the case of liquids bottled under pressure and also when the bottle is transported by aircraft, where the reduced atmospheric pressure at higher altitudes produces an effect tending to cause leakage of the contents from the bottle.
I claim:
1. A closing device for bottles having a neck portion provided with projections adapted for screw-engagement with a cap on the outside thereof, which comprises, in combination: a cork adapted for insertion into the bottle mouth in the neck of the bottle so that one end portion of said cork protrudes therefrom; a cover of smooth, rigid material on said protruding portion of said cork; a cap consisting of a skirt portion and a bottom portion for enclosing the neck and the mouth of the bottle, said skirt ortion being provided with projections for screwing engagement with said projections on the outside of said neck of the bottle, and said bottom portion being formed with a hole through which said protruding portion of said cork extends hereby loosely filling the hole, and a flange on said cover adapted to engage the inner side of said bottom portion of said cap and to close said hole when said cap is screwed on the neck of the bottle.
2. A closing device for bottles as defined in claim 1, wherein the free end of said cover is provided with a salient part of such dimensions that said salient part of said cover is not capable of being passed through said hole in said cap bottom.
3. In combination, a bottle having a neck portion provided with projections on the outside thereof for screwing engagement in a cap, said bottle also having an outwardly directed pouring lip; a cork, one end of which is adapted for insertion in the mouth of said bottle in order to close said bottle, the other end of said cork being adapted to project out from said mouth of said bottle; a cap adapted to enclose said neck of said bottle and to surround said pouring lip of said bottle without contacting said pouring lip, said cap being provided with a bottom portion having a central hole, and with projections for screwing engagement with said projections on the outside of said neck of said bottle; and a cover enclosing said projecting end of said cork, said cover loosely filling out said central hole in said cap bottom. and being provided with salient portions at each of its ends, said salient portions having dimen-- sions such that said salient portions of said cover cannot pass through said central hole in said cap bottom, said salient portion which is innermost with respect to said neck of said bottle being formed as an outwardly extending flange of said cover, adapted to close said hole when the cap is screwed on the bottle neck.
