signor to No-Kap Closures (U. S. A.) Inc., Providence, R. 1., a corporation of Rhode Island Original application June 29, 1933, Serial No. 678,133. Divided and this application March 31, 1937, Serial No. 134,162. In Great Britain July 5, 1932 34 Claims.

The present invention is a divisional application of my application for Method and apparatus for making containers, Ser. No. 678,133, filed June 29, 1933, which is a continuation in part 01' my co-pending application Ser. No. 629,007, filed August 16, 1932.

The present invention has for its object improvements in containers and more particularly in containers or tubes deformable by compression and containing fluid, viscous or pasty material.

According to the present invention, a container of the kind referred to comprises a movable closure member or stopper fixed at the extremity of the container, of which the material is pressed or extruded around it, and provided with an exterior finger or member for manipulating purposes allowing of its being displaced and for example of making it turn to open or close the container.

According to one way of carrying out the invention, the closure member comprises 9. diametrical conduit which may be brought into register with the prolongation of the neck or orifice of the container, when this latter is to be opened, or be angularly displaced so that the body of the closure member covers the said neck or orifice and ensures the closure.

The positioning of the closure member at the discharge end of the container is eflected. according to one manner of carrying out the invention, during the formation of the container; and to this end, the closure member is placed in a mould of suitable shape, then above it, a round or blank of metal; this blank is then extruded by a punch for the one part round said closure member, forming thus the head of the container partly enclosing the closure member in a fluid-tight manner, and for the other part round the punch, thus forming the tube itself.

According to a modification both the head or neck of the container and the top of the container are formed in a first step by extruding between a punch and an appropriate matrix, then in the second step the closure member (which is provided with two recesses) is disposed in recesses in the neck, the bosses or pivots oi the closure member being formed by the material of the neck which penetrates during this second step into the said recesses.

Further features of my invention relate to a novel type of closure means adapted-to be used either with collapsible tubes or to serve as stoppers in connection with a cork or otherwise for any container, such as a bottle, etc., one embodiment of my invention being so constructed as to permit only one drop to be delivered at one time, another embodiment being provided with two vents for the free discharge of fluid therefrom and a still further embodiment being so constructed as to dispense a measured dosefrom the container.

Further features of my invention relate to the novel methods of manufacturing such a closure means for any type of container whether it be a bottle or a collapsible tube and in which I provide a neck member for the closure constructed of pressible material and preferably having a recess therein and I insert the closure means within said recess and press the metal of the neck or nozzle partially around said closure means to retain it within said recess.

So far as I am aware I am the first to provide an automatically movable member for closures for nozzles, which may be readily moved by hand from an open to a closed position and which is normally retained in position in the nozzle by the metal of the neck or nozzle itself being pressed around the outer portion thereof to retain it in said movable position.

The following description, with reference to the accompanying drawings, given by way of example, will make the improvements easily understood.

Fig. 23 is a side elevation of the closure means of the embodiment shown in Fig. 22.

In the embodiment illustrated in Figs. 1 to 3 the container a which is deformable by compression, comprises a cylindrical nozzle or neck b in which is partially enclosed a closure member d so that it can turn, said closure member being provided with a conduit e giving communication between the interior of the receptacle a and the exterior. This closure member may be provided with a rear portion in the form of a flat key d, whilst the body of the closure member is formed by a surface of revolution about an axis perpendicular to the surface of the tube and of which the generating line may be formed by the curvesh, la, fa, 14. The curves may be replaced by straight lines, so that the closure member would then have the form of a double cone.

The nozzle b comprises a housing which conforms in a fluid tight manner to the form of the closure member, that is to say presents as hollows the surfaces of revolution or cones having for generatrices the curves or straight lines f1, fa, f1. ii-

The nozzle b may or may not be provided with a shoulder h on which is embedded the part forming the key d and which may form an abutment thereto in the open position.

The manufacture of the nozzle b and the retention in place of the closure member d are effected as will hereinafter be described by way of example, in regard to Figs. 2 and 5.

In the'manner of manufacture illustrated in Fig. 2, the closure member has the form of a small barrel, that is to say is provided with two parallel plane retaining faces 11', d to which correspond the two equally plane and parallel retaining faces of the nomle b.

The closure member may thus turn about the axis x Fig. 3 which is normal to the axis of the container or tube, the manipulation being effected simply by turning the handle or key d.

As before, the closure member comprises a conduit e and it is seen on referring to Fig. 2 that, in the position indicated in full lines, the contents of the container or tube may be elected from the tube in the direction of the arrows, when the opposite end of the tube a is pinched in the usual manner. when the tube is finished with, it is sumcient to return the finger d into for the closure member to close the neck c of the container or tube a and prevent the contents of the tube or container coming out.-

On referring to Figures 2 and 3 it is seen that the closure member is enclosed in a fluid tight manner on the nozzle b, so that it is permanently retained in the said nozzle and that it may in spite of that turn fully about the axis XX. in other words the nozzle serves as a fluid tight support for the closure member.

The manufacture of the closure member may be carried out for example as represented in Figs. 6 and '1 starting from a drawn out rod of steel or other metal D which is placed between a cutting die E and a counter-partial die E, Fig. 7 representing the operation after cutting the closure member (1 in the rod D.

The conduit e is then. pierced in the closure member d.

Of course, the orifice in the closure member may be pierced after the latter has been put in place in the nozzle. of the container or tube.

The disposition and the retention of the closure member d in the nozzle b of the tube or container a may be obtained as will be hereinafter described with regard to Fig. 5, during the formation of the tube nozzle.

To this end, the closure member is disposed in the mould i with its handle d turned downwards and engaged in a recess in the usual ejector a, which ensures the centering of the closure member. Above the closure member, in the usual manner, in the mould i is placed a blank of suitable thickness made of metal or alloy from which the tube or container a is to be formed.

The punch k, provided as usual with an airescape valve i, is made to descend, the descent of the punch producing the compression of the blank and the flowing or extruding of the metal, for the one part around the closure member, between the latter and the base of the mould, thus forming the nozzle b surrounding the said closure member, and for the other part, the extension of the metal whichrises round the punch in the form of a tubular sheath in the direction of the arrows, thus forming the tube a.

When the operation is finished, the punch k is raised, and, on actuating the elector, the assembled tube and its closure member are disengaged, the said assemblage being as indicated in Fig. 2, that is to say in the finished state.

The filling of the tube and its closing are effected in the usual manner.

In the form of embodiment illustrated in Figs.

8 and 9, closure member d, in place of having the form of a little barrel, is spherical and may be displaced in two perpendicular directions, the external face b of the nozzle being provided thus with a groove 1) in the form of a right angle, as indicated in Figs. 8 and 9.

Under these conditions, on leaving the position of the said Fig. 9. at which the conduit e puts the container 0 in communication with the exterior, the tube or container can be closed on moving the handle d in the direction of the arrow F, as previously described with regard to the closure member illustrated in Fig. 2; but furthermore the security can be assured by pushing the handle (1 in the direction of the arrow 1", that is to say in a direction perpendicular to the direction F, so that the said handle d may be thus held against all displacement in a sense opposite to the arrow F.

To use the tube, and to open the closure membar, the opposite procedure must be adapted, that is to say, the handle (1' must be made to undergo two consecutive displacements in perpendicular directions.

In the embodiment illustrated in Figs. 10 to 14 the closure member or stopper d, which is provided with a handle d, is solid and of hemispherical form. It is provided with two recesses 01 diametrically opposite into which the material forming the neck is pressed at the moment oi positioning the closure member into the head or neck of the tube a; the teeth or projections b (Fig. 14) formed by the entering the material into the recesses 11 constitute the pivots or axes of oscillation of the closure member or stopper d. This latter is raised on its lowerface as indicated at d (Fig. 11) and it will beunderstood by reference to Figs. 12 and 13 that according as the handle d is in the lower or upper position, the receptacle is closed (Fig. 12) or open (Fi 13).

In the latter case, the material contained in the tubes issues obliquely (as indicated by the arrow F) between the upper edge of the neck and the wall d The manufacture of tube a and of its neck b, also the positioning of the closure member 11, illustrated in Figs. 10 and 11, in the recess or neck b, may be embodied as will be subsequently described with referenceto Figs. 15, 16 and 1'7.

In the first step the blank of material b destined to be extruded to form the neck and tube is disposed in the bottom of the matrix, about a piston 1' provided with prolongation i and with a spherical part i slightly projecting. The punch k engaging the matrix is provided with a central conduit k which the prolongation of the piston a fits closely.

The different parts being in the position illustrated in Fig. 15, the piston 7' is slightly lowered to bring it to the position illustrated in Fig. 16. The punch k is lowered so that a certain amount of material enters the space between the spherical part :i' of the lowered piston (i and the wall 1' of the central orifice of the matrix 2' in which said piston is disposed, thus forming the neck b of the receptacle.

Furthermore, metal is extruded between the punch It and the matrix and leaves in the form of a tube a (Fig. 16) around the said punch.

When the pressure terminates, the assemblage of the piston 7' and of the punch It has risenagain until the piston 5i returns to the position illustrated in Fig. 15, whilst the punch It continues to be raised, which separates the neck '19 and the spherical part i of the piston.

The piston 7' is then replaced by another piston m (Fig. 17) on which the closure member (1 has been suitably disposed; and the said closure member is caused to enter the neck I: by the lowering of the punch, the metal of the neck being, during this operation, pushed back or pressed into the recess cl of the closure member and forming as above described the boss or pivot of the closure member. The punch k is then raised and the tube is ejected simply by injection of air into the prolongation k of the central conduit k: of the punch k.

The closure of the tube formed, as has been indicated, by the stopper d, is absolutely air tight; and in spite of that the operation of opening the tube is extremely easy. 1

The closure member or stopper-is run formed by running its material into a mould or is formed 'the fluid therein, which is firmly retained in the nozzle. the metal of the nozzle itself being pressed around the outer end of the closure member and the improved method of its manufacture. In the embodiments hitherto described I have shown and described my invention as applied to a collapslble tube.

It may, however, if desired as shown in Figs.

,\ 18-23 be applied to a bottle, in which case the stopper (1 is inserted as usualin the neck b, the lower portion m of which may be suitably mounted within a suitable cork n forming the stopper for the bottle a If desired the neck or nozzle 01 may be provided with the supplemental outwardly flaring flange 0 adapted to rest on the upper end of the bottle neck t. In this instance the conduit or vent e is constructed of tapering shape and of a size to only dispense a single drop at a time from within the bottle a and hence may be used in similar fashion to a medicine dropper. The hole e may be of any predetermined size togive the drip required. This type of dispenser will be extremely useful in dispensing drops of medicine. seasoning. bitters, etc. The embodiment shown in Figs. 20 and 21 is generally similar to the embod ment shown in Figs. 18 and 19 with the exception that in addition to the fluid discharge vent e a supplemental air inlet R is provided to admit air within the bottle therethrough as the liquid is being withdrawn out through the outlet e, thereby providing a closure member which will permit a rapid discharge of liquid from within the container. I have shown in Fig. 22 a dispensing device for bottles generally similar to that shown in Figs. 18-21 with the exception that the nozzle e is enlarged at e near its upper end and the stopper member (2 is made hollow as at cl and in place of being provided with the vent that goes all the way through, is provided with a sector shaped opening I, the closure means being otherwise constructed in similar fashion to that shown in the just described embodiment. This type of closure means is adapted to receive within the hollow interior d of the closure member d a measured dose of medicine, liquid, or other type of liquid through the opening 1 thereimthe bottle being .tilted for dispensing purposes. When the hollow interior d is suitably filled with liquid through the medium of the handle d the stopper (1 is tilted to an open position, thereby shutting oiT the supply of liquid from the neck m by bringing the hollow closure member (1 opposite it and bringing the open portion of the hollow stopper member in alignment with the opening 11 in the top of the container and permitting the liquid to be dispensed therefrom. In the claims I employ the words extruding dies and extruding, as defined on page 904 of Webster's New International Dictionary, 2d Edition, as A set of shaping dies that cause small'blocks of ductile metal to flow into any desired shape, especially into the form of cylindrical tubes for tooth pastes. Said definition is further limited by having the word extrusion mean flowing through a hole and in more than one direction. I

It is evident that modifications may be made in the devices above described, without departing from the scope of the invention. In particular, the closure member may be rendered movable not I member contained within said recess, a projection projecting outwardly through the end of said nozzle from said closure member to move said closure member in and out oi positions completely closing said nozzle, said closure member having diametrically opposite single axis of oscillation forming means thereon, the wall of said nozzle being integrally complementally shaped adjacent said diametric axis forming means to cooperate to form therewith cooperating male and female single fixed axis forming means.
