I "Ihisinvention relates to bottles or containers and more especially to devices for effecting removal of the liquid contents of a bottle or other container in increments or doses which devices 5.; alsoform closures for said container.

of iiquid, and a-well or other receptacle, hereinafter termed T a 1well, which receives the liquid dose thus: displaced. V The present invention relates particularly to, devices of this character.

.Ittisone object-of; the invention to provide an improved; devicecf this character which will readily supply the required liquid dose even under the varyingconditions met with in practice such as variation in the liquid content of the bottle, variations in roomtemperature and the like.

. A further'object of the invention is to provide a construction wherein the actuation of the diaphragm isymore effectively controlled and wherein the diaphragm and the well associated therewith are constructed so as to provide a maximum of movement with minimum strain of the diaphragm. v Anotherobject is to provide a construction of device of the abovementioned character which is of compact form so as to occupy only'about the same space as a closure of normal construction. V

Other features of the invention will be apparent from the following description.

V

F 3 is a view on an enlarged scale of a detail shownin Figs. 1 and 2.

Figsgl a'nd t'i; are views-showing another arrangementlinits normal and operative positions respectively, and 7 Figs. 6 and? are. similar views of another modif m. 11:

,Like reference; numerals indicate corresponding partsin all the figures.

Infthe forms shown in Figs 1 and 2 the bulk container for the ink or other liquid takes the form of a bottle 1 having a relatively wide neck 2; which is screwed externally at 3 and in which the well 4 is axially disposed, the said well being secured to the bottle in a fluid-tight manner by means of an annular flange 5 forming part of a resilient diaphragm 6 formed or provided on the well 4, This flange or diaphragm 5 is adapted to seat itself upon the upper edge I of the neck of the bottleand to be secured by means of a cap 8 having a downwardly depending portion 9 which is pressed to define aninternal screw, the internal screw being adapted to engage the external screw 3 on the neck of the bottle, whereby the inwardly projecting annular flange ID of the cap is adapted to press on the part 5 of the diaphragm and thus maintain the said well and diaphragm in fluidtight engagement with the bottle.

The lowest internal part of the well 4 is apertured and provided with a tube l Z'through which the liquid in the bottle is adapted to pass upward to the well 4; the free end of the tube is located in the lowest position inthe interior of the bottle whereby the whole of the liquid in the bottle can be passed to the well. The well 4, however, projects upwards from the diaphragm 6 to define an annular ledge 13 on which a second cap I4 is adapted to bear, this cap having a downwardly extending portion l5 which is screwed at IE to engage an external screw on the inner cap 8.

A metal rubbing washer ll to diminish the friction due to relative movement of the parts is interposed between the upper face of the annular ledge 13 and the annular face of the external cap M. The upper end l8 of the well is preferably formed with a bead which, with the annular ledge I3, defines a groove I9 into which the inner edge of the external cap I4 is adapted to project to limit the movement of the said cap, the arrangement of parts being such that the rotation'of the external cap I4 over the fixed inner cap 8 depresses the diaphragm 6 inwards and thereby reduces the capacity of the interior of thebottle I to cause a portion of the fluid in the bottle to pass upward into the well. Conversely, by rotating the external cap it in the reverse direction, the diaphragm 6 rises and any liquid remaining in the well 4 is caused to pass downward into the bottle. A valve washer 20 (see Fig. 3) is located in the well 4 and rests on a ledge formed in the well whereby the washer is spaced apart a short distance from the bottom, the said washer being provided with one or more apertures 2| ofiset from the aperture in the well and communicating with the tube l2, by which means squirtingor splashing of the liquid during its passage from the tube l2 to the well 4 is avoided. This valve washer 2|] may also act as a stopper or Cal closure by the addition of a suitable plug (not shown) inserted in the body of the well and adapted to press on the washer for example of the type shown in Fig. 4 but of sufiicient axial extent to contact washer 2B. In cases where the tubular member I2 communicates with an aperture in the side wall of the well at the lowest part thereof, this valve washer 20 may be dispensed with, as the ink or other liquid, on leaving the tubular member l2, will impinge on the side wall of the well.

Figs. 4, 5, 6 and 7 illustrate other applications of the invention wherein the inner cap is nonremovably secured to the bottle by so forming the cap that the lower free edge is adapted to be turned inwards to overlap the lower annular portion of the neck of the bottle.

In Figures 4 and the bottle I is shown having its neck 2 formed with a plain annular thickened portion 36, the well 4 and its associated diaphragm 6 being secured in a fluid-tight manner within the neck 2 by a cap 31, the lower free edge of which is turned inwards as at 38 to non-removably secure the cap to the bottle. The well 4 is provided with a shoulder 39 on which a second cap 40 is adapted to bear. The shoulder 39 may be provided with a metal rubbing washer I! as described with reference to Figs. 1 and 2. This second cap has a dependent substantially cylindrical portion 4|, the free edge of which is rolled to form a bead 42 in relation to which the cylindrical wall of the second cap is medially disposed, the inner part of the bead thus forming an inwardly directed lip round the free edge of the cap.

The inner cap 31 and the outer cap- 40 are provided with substantially vertically disposed cooperating projections 44 and recesses 45 respectively, so formed that when the projections and recesses are in engagement with each other the cap 40 may be moved freely in a vertical direction only relative to the cap 31, but when the cap 40 is depressed to such an extent that the rim 42 of the cap comes below the lower ends of the projections 44, the cap 40 can then be partially rotated to cause the lower edge of the projections 44 to engage the edge of the cylindrical head and the cap is thereby retained in the depressed position.

A stopper 4'! may be provided to close the top of the well 4.

In the modification illustrated in Figures 6 and 7, the cap 31 engages at the inner edge of its annular top face with the vertical cylindrical surface 49 of the shoulder 39, and the second cap 40 fits into a groove formed between the shoulder 39 and a bead 48 surrounding the mouth of the well 4. The well is emptied or filled by raising or lowering the cap 40, as the case may be, to operate the diaphragm. The well is adapted to be retained in the desired position by the frictional grip between the cylindrical face 49 and the inner edge of the annular top face of the cap 31.

I wish it to be understood that in all the forms of bottle hereinbefore described the well may be fitted with a washer 20, arranged and operating in a similar manner to that described with reference to Fig. 3, or alternatively, the tubular member may be so disposed that its upper end communicates with an aperture in the side wall of the well, whereby the ink or other liquid will be ejected in a lateral direction.

Further, while the well and diaphragm are preferably made of rubber, the well can be made of synthetic resin or similar mouldable material and the diaphragm can be made wholly or partially of any suitable resilient material, or may be of rigid material resiliently connected to the well and/or the bottle. The diaphragm may be formed integral with the well or separately therefrom and subsequently secured thereto, in which latter case, thin metal may be employed resiliently connected to the body of the well with or without the provision of a washer to ensure air and fluid-tightness between the diaphragm and the upper part of the bottle. The caps may be formed of metal, synthetic resin or other rigid material.

The bottles and caps may be of any suitable shape depending upon practical and/or aesthetic requirements.
