20 Claims.

' 5 simple closure or cap for containers which remains on the containen at all times, whether the container is open or closed, smthat the cap or closure is not lost. A second object of this invention is to provide \,a closure for a container which allows adjustments between the open and closed positions, so that there are intermediate partially open positions, controlling the dispensation at will.

A third object of this invention is to provide a double closure of the channels through which dispensation takes place. More particularly, in connection with dispensing necks,` an inner as well as an outer closure for the dispensing opening are comprised in one cap. A further object of this invention is to provide a closure in which the container or an extension thereof or the closing means are in slidable abutment at substantially all points, so that a. rela-- tively thin material may be used for the various parts, 'the various thin layers of abutting parts reenforcing each other.

Still another object of this invention provides for an enclosure which may be manipulated with extreme ease, so that the container as well as the opening and closing thereof may be brought about by manipulation with one hand only, the other hand of the user being free to be used otherwise.

Another object of this invention is to provide slidable means on a container, which provide a double or triple closing, so that not only liquids, but also fluids generally, for instance aromatic liquids, may be kept in such containers, ready for instant use and still tightly closed.

A further object of this invention is to have, in

l connection with a cap which provides a double closure, means displacing on the closed container the fluid to lbe dispensed from all voids of the closure which it may ll while the closure is open.

Additional objects shall be brought forth and will be more readily understood from the following description and the accompanying exemplary illustrations, of which: Y

Figs. 1 and 2 show collapsible tubes closed by closures or caps of my invention, the former being directed to an arrangement with a control by rotation, the latter a modiiication in which the closing is controlled by reciprocating the cap.

Figs. 3, 4, 5 and 6 are detailed sections corresponding to the showing of Fig. 1:

' 55 Fig. 3 shows the closure in a closed position and is the top view of a. cross-section at a level indicated by a dot-dash line and by numeral 3 in Fig. 5.

Fig. 4 is a corresponding view in which the closure is open.

Figs. 5 and 6 are cross-sectioned elevations of the upper end of the closed and open container, respectively.

Fig. 9 shows an elevation of the upper end of the container of Figs. 1 and 3 to 6, without the cap or closure. I

Figs. 7, v8 and 10 to 12 relate to the modication shown in Fig. 2:

Figs. 'I and 8 show cross-sectioned top views of the closed and open container, respectively, said cross-sections being taken along lines identified by the numerals of said figures in Figures 10 and l1.

Figs. 10 and 11 are sectional elevations corresponding to the positions of Figs. 7 and 8, respectively. v

The, cross-section of Fig. 12l is similar to that of Fig. 10, but shows a modified shape of the cap.

Fig. 13 is the elevation of a. bottle provided with 4my closure.

Figs. 14 and 15 show cross-sectioned elevations of the upper end of such a bottle, the closure being in an open position in the former and closed in the latter ilgure.

Figs. 16 to 19 serve to illustrate another modiilcation of my invention:

Figs. 16 and 17 are cross-sectioned elevations in which the closure is in a closed and opened position, respectively. i

Fig. 18 is a side view of a plug used in the modication of Figs. 16 and 17.

Fig. 19 shows a front view of the neck of the respective container. y

Figs. 20 to 24 illustrate containers and caps or closures of my invention which may be rotated and as well may be moved axially relatively to the container.

Figs. 20 and 21, respectively, show the crosssectioned elevation of a modified closure in a closed and open position; the cap moves along a spiral path when opened or closed. In Fig. 20, holes are omitted.

Fig. 22 shows a side view of the neck of the bottle of the-modifications of Figs. 20 and 21.

Figs. 23 and 24 show, in similar views, necks, which are provided with various guide grooves.

Figs. 25 and 26 show, in open and closed positions respectively, cross-sectioned elevations of another modification of my invention, which provides an extension on the container; that exf.

sov

tension cooperates with the closure and forms part thereof.

Similar numerals refer to similar parts throughout the various views.

Figs. 1 and 2 exemplarily show collapsible tubes 3| and 32 which are executed substantially according to present-day practice in this art, except that the respective necks 33 and 34 are particularly shaped in accordance with my invention. Upon the necks 33 and 34 of the containers of Figs. 1 and 2 are applied the closures 35 and 36, respectively. Figs. 3 and 4 show the cap 35 to be depressed at one point, and the resulting indentation 31 extends into a substantially semi-circular groove 38 provided in the neck 33.

At one side the cap 35 is perforated by an opening 39 which is shown to be circular but which may assume any shape Apreferredly suited for the dispensation of the contents of the container or collapsible tube 3|. l

The cap 35 is arbitrarily indicated to be slidably rotatable through substantially 180 upon the neck 33; the extent to which said cap may be rotated is determined by the length of the groove 33, the ends of which serve as stops for the indentation` 31 of cap 35. At` one extreme position (Figs. 4 and 6) of'rotation of cap 35, the opening 39 in the cap 35 registers with an opening 40 in the neck 33. If the opening 39 is disposed substantially at the level of the upper part of the neck 33,-as it is exemplarily shown in the drawings,then the opening 46 may assume the shape of a notch (Fig. 9), extending down into the neck 33.

In the cap 35 is xedly mounted a hollow or solid core or plug 4|, the upper end of which, the head 42, forms part of said cap or substantially nts diametrically into the cap 35, abuts upon the bottom of said cap, which is suitably fastened therein, for instance by the dents 43 of said cap, which are depressed into correspond.- ing indentations in the head 42, so that the cap and plug are in a relatively ilxed position. The

head slidably abuts upon the neck 33, and an extension, a stem 44, depends in slidable abutment from the head 42 into the opening of the neck 33. The stem 44 is provided with a recess 45, which downwardly opens into the container and which also issues through one side of the stem in registering alignment with the opening 39 in cap 35. It will be understood that the groove or recess 45 also registers with the opening or notch 40 in the neck of the container, when the cap or closure 35 is in the open position of Figs. 4 and 6. But in the closed position of Figs. 1, 3 and 5, the recess 45 is laterally closed by the wall of neck 33, and in that position said wall also closes the opening 39 of the cap; whereas in that same position the opening or notch 46 in the neck 33 is closed at one end and at the top by the stem 44 and the head 42 of the plug 4|, respectively, and at the other end by the wall of the cap 35. A double closure of the containery or collapsibletube 4I is therefore provided for as soon as the opening 39 and groove 45 on one hand, and the opening and notch on the other hand have been shifted out of registering alignment.

an arrangement in a closed and open position, respectively.

In analogy to the arrangement of the prior modification, the cap 36 with perforation 46 is exemplarily attached by the dent 41 upon indentations in the head 49 of the plug 48, but the stem 50 of plug 48 and the cylindrical part of cap 36 are longer, in order to bring about a double closing in the covered position 'of the cap of Figs. 7 and 10 and in order to provide the necessary mechanical guidance in the raised .and open position of Figs. 8 and 11.

The neck 34 of the container or collapsible tube 32 is provided with longitudinal (vertical) groove 5| in which is slidably disposed the depressed dent 52 of the cap 36. The recess or groove 53 in the stem 50 registers with the opening 46, and they both are closed by the neck 34 in the position of Fig. 10. In the open position of Fig. 11, in which the cap 36 is raised, the opening 46 and opening, groove or' recess 53 register with a hole or opening 54 extending through the wall of the neck 34 so that in that position the contents of the container or collapsible tube may be dispensed.

The modiiication of Fig. 12 corresponds in respect to most details with the modiication just described, but the plug 48 is provided with a diifer'ently shaped head 55, said head exceeding in diameter the diameter of the neck 34. Correspondingly, the cap 56 of this modication is bulged out at the bottom to fit around said large head 55 of the plug 48, thus offering a knob-like part, which facilitates engagement and gripping of the cap for the purpose of manipulation in the opening and closing operations. Of course the upper part of the plugs 4| or 48 may thus be shaped at will, and the outer surface of the cap may be variously adapted, e. g., by knurling, to such purpose or for purposes of adornment.

While I reserve the right to apply any materials for the various parts of my invention, the selection of which,-for the cap, plug and also for the neck of the container,suggests itself to those versed in these arts, it is understood that certain materials prove particularly useful on account of economic or manufacturing considerations. While the cap is preferably made of metal and preferably drawn or stamped and may thus be executed very thinly, I find certain mouldable materials, e. g., condensation products, to be very useful for the plug.l Of course the materials should be chosen so as not to corrode or swell under the influence of the fluids accommodated in the container.

While collapsible tubes ordinarily are made of metal, and therefore the neck thereof might also be made of metal, there are many containers, e. g., bottles, in connection with which glass is the mostly used material. For that reason the containers in the remaining figures are indicated to be executed in glass. Y

While glass containers at the present state of development of the arts may be moulded very close to the desired dimensions, it may be preferable to provide in connection with glass, as well as with the containers, several steps, for instance on the inside of the neck 6| of a bottle 62, so that a closure at one or the other point, either in peripheral slidable abutment or in endwise axial abutment is assured. The stem 63 of the plug 64 used in connection with such a bottle may accordingly be recessed at 65 near its lower end, the interior of the neck 6| of the 75 6| of the bottle 62 serves to guide the circular movement of the cap and the radial hole 1| in stem 63 merges 'with an axially disposed hole 12, registers with the hole 13 in cap 69, and may be shifted into alignment with the hole 14 extending through the wall of the neck 6| when fluid contents of the bottle are to be dispensed.

When it is desirable to provide a container in which all contents, remaining in the container when not in use, are separated from the outside by a double closure, such a void as occurring in the prior arrangements at 40, 54 and 14 may be eliminated by combining with the closure a part which iills said void when the bottle is closed. Such a part is indicated at 16 in Fig. 18, representing a key, which forms part of the stem 63 and which matches a square notch 11, provided at the upper end of the neck 6| of the container.

If the cap 69 of such an arrangement is to be retained at all times upon the bottle, an indentation 18 and a longitudinal (vertical) groove 19, corresponding to the arrangement of Figs. 7, 8, 10 and 11,may be provided for, and the head may of course assume any preferred shape like that of Fig. 12.

Since the notch 11 is shown to be rectangular, and since the key 16 is correspondingly shaped, the dispensing opening 80 in cap 69 may also be shaped oblong or square, so that the contents of the container may be dispensed in a preferably shaped jet, and the cross-section of said jet is varied according to the height to which the cap is adjusted during dispensation.

The guide groove in the neck of the bottle, which determines the path along which the cap is moved for the purpose of opening and closing the container, may of course be variously disposed. The groove 83 of the modication of Figs. 20, 21 and 22 is for instance helically disposed so that the cap does not only rotate, but also moves up and down during opening and closing; such an arrangement entails various advantages; thus for instance an arrangement of this kind will tend to avoid a binding of the parts upon each other because they peripherally as well as axially slide upon each other. When the groove 83 is disposed at an angle of 45, and the dispensing opening 84 is square, the jet dispensed will always be square when the closure is fully or partly opened, just as such a square jet will always be provided for if the openings of the prior modications are diamond-shaped.

'A dispensation by way of a plurality of jets may readily be provided for; and for other purposes, a plurality of openings may be doubly closed by means of my invention, or such additional openings may be provided for in order toC vent the voids which are enlarged or disappear during the opening or closing of the concap, neck and stem, into the groove 86 in said stem.

In connection with the modication of Figs. 16 to 19 the guide groove 19 may be omitted. In that case the closure may be opened and closed and may also be Afreely removed from the container. In order to provide for such removal in Y connection with containers using my invention in other modifications, and for instance where the container is to be conveniently refilled, I may provide angular extensions of the guide The groove 88 on the neck 6| kof Fig. 23 is for instance provided witha vertical extension 89 at one end, which clears the indentation 31 guided in groove 88 so that the cap may be removed. Such an extension may be provided in connection with grooves 38 or 10. Where there is a vertical groove 90, like groove 5| of Figs. 10,'

11 and 12, said groove may be extended to the right by a section 9| and then I may again provide a vertical section of a. groove 92 connecting with the end of section 9|; thus the indentation of the respective cap may be moved from a closed position at the bottom of groove 90 to an open position at the ,top end-of said groove, as before. and vice versa; but then the indentation may be swung at the said top level to the right along groove section 9|, and along section 92 out of engagement with the neck of the bottle, whereby -the cap is removed from the bottle.

It will. be readily seen that a separate extension 94 may be provided upon the bottle, which is tightly beaded at 95 over a rim 96 encircling the neck 6| and which forms an extension in the 'shape of a Asleeve above vthe top of the neck of the bottle and which Wholly or partly abuts upon the shiftable closure. In connection with this arrangement I also show a variation in the arrangement which serves to engage the closure upon the container so that it cannot be removed. Instead of providing an indentation in the outer cap which engages upon a groove in the container, I here show an indentation 91 in the extension 94 which is slidably engaged upon a groove 98 extending around plug 99. The plug 99 may o'f course be completely disposed on top of the container neck 6| proper, or a stem extension |90 may depend therefrom into the neck of the bottle or container, and engage upon the inside'of the neck of the container in slidable abutment. It will be seen from Figs. 25 and 26 that this arrangement allows the channel or opening ||I| between the outer cap |92 and the plug 99 to be made extremely short, because the extension 94 may be a thin sleeve.

The converse,v concentric sleeves extending from a container, a single cap extending therebetween and suitable openings extending through said sleevesI and cap within the meaning of this invention, suggests itself to those skilled in these arts. 'I'herefore this invention is notvlimited in scope to the exemplar showings disclosed but I desire full protection within the following claims.
