H. w. FISHER LFLUID' DISPENSING DEVICE Filed May 5, 1933 ATTORNEYS Patented @ct. 10, 1933 UNITED STATES PATENT OFFICE l- 8 Claims.

The present invention relates to a fluid dispensing device which is particularly useful in handling a cleansing fluid such as gasoline.

The primary object of the invention is to provide a fluid dispensing device, specifically a bottle with a closure member or cap therefor, by means of which a cleansing operation can be performed without removing the cap simply by turning it slightly to permit egress of fluid upon 19 inversion of the bottle and then rubbing the spot to be cleaned with a pad of felt or other similar material affixed to the top of the closure member.

A more detailed recitation of the objects of 1 my invention includes (1) the provision of a bottle having a cap which can be rdtatedin one direction to seal the bottle against egress of fluid and in the other direction to permit discharge of a limited quantity of the fluid which 90 is just suflicient for convenient application in a cleansing operation; (2) the provision of a device of the character described in which adequate distribution of the fluid over the area of the cleaning pad may be effected; (3) the pro- 5 vision of a cleaning bottle of the character mentioned in which 'the cap or closure member is non-removable so that the bottle cannot be refilled without distorting or impairing the usefulness of the cap; (4) the provision of a device of this character which is of simple yet sturdy construction, easy to manufacture, and reasonable in cost.

The nature of the invention and its objects will be more clearly apparent and better understood in connection with the following descrip-- tion of the accompanying drawing, wherein- Fig. l is a vertical section through the upper portion of a bottle equipped with my improvements showing the cap in the position which it assumes when the bottle is tightly closed.

Fig. 2 is a side elevation of the upper portion of my improved device taken in a direction at right angles to the section of Figure 1, but with the outer protecting cover removed.

Fig. 3 is a side elevation of the neck portion of my improved bottle taken at right angles to the elevation shown in Fig. 2 and with a portion of the neck broken away to illustrate certain features of the construction in section.

Fig. 4 is a plan view of the neck of the bottle. Fig. 5 is a section of the neck of the bottie with the cap in place showing the position which the latter occupies during a cleansing 0peration.

In connection with Figs. 1 and 5, I should like to point out that the sections illustrated in these figures are taken approximately as indicated by the section line with the arrows appearing in Fig. 4,-although it will be understood, of course, that the cap in Fig. 1 occupies a different circumferential position than it does in Fig. 5.

Referring to the drawing it will be seen that the neck portion 8 of the bottle 9 is provided across its top with a substantially flat web portion 10 in which is formed the eccentrically disposed aperture 11 through which the cleaning fluid can be discharged when the cap is in position to permit such discharge, as will appear hereinafter.

At its upper margin the neck is provided with a shoulder or head 12 which is cut away at two diametrically opposite points to provide the channels or grooves 13.-

Just below the shoulder 12 there is formed on the neck a pair of oppositely disposed sections of a right hand cam 14 and a similar pair of op- 'positely disposed sections of a left hand cam 15.

Adjacent sections

14 and 15 meet in a stopsshoulder 16 and extend substantially half-way around the neck of the bottle so that each section 14 occupies roughly only one-quarter of a circumference and each section 15 another quarter of the circumference. However, there are two right hand sections 14 located at diametrically opposite points, as well as two left hand sections 15 also diametrically disposed to occupy substantially the other two quarters of the circumference.

Adjacent sections

14 and 15 terminate at points substantially 180 apart so as to provide the vertical channel or groove 13a. at each side of the bottle, which channels are, in effect, continuations of the channels 13 formed-in the bead or shoulder 12. The effect of the arrangement is to provide the bottle neck with what may be termed a half-right-half left hand cam surface.

The closure member or cap used in connection with my improved dispensing device includes a cup-shaped sealing member 17, the side wall or skirt 18 of which fits down around the top of the neck of the bottle in order to embrace the shoulder 12 and the

cams

14 and 15.

At two diametrically opposite points the skirt 18 is provided with the indents 19 which, when the cap is placed in position, are adapted to fit into the slide through the vertical grooves or

channels

13, 13a. Upon subsequent rotation of the cap it will be clearly understood that the indents 19 will engage beneath the cams 14 when the cap is turned in one direction and beneath the cams 15 when the cap is turned in the opposite direction. In either direction, however, it is obvious that the cap will be tightly held against the top of the bottle in order to prevent leakage.

Interiorly the cap is provided with any suitable type of washer or gasket member 20, preferably of cork.

Eccentrically disposed but located on the diameter which passes through the two indents 19 the cup-shaped cap 1'7 is provided with a relatively restricted discharge orifice or outlet 21, and the gasket member 20 is provided with a suitable aperture 22 adapted to register therewith, al-

though the aperture 22 may be of larger diameter if desired. In fact I prefer to make the aperture 22 of a diameter substantially corresponding to the diameter of the discharge opening 11 in the web 10 of the bottle neck. The gasket member 20 may be held in place in any suitable or desired manner.

The cap member is also provided with a domeshaped supporting plate 23 having a plurality of perforations 24, which plates serves as a backing member for the cleaning pad 25. The pad may be made of felt or any other porous and absorbent material suitable to the purpose.

The lower edge of the plate 23 is bent outwardly and upwardly around the edge of the felt 25, as indicated at 26, and by crimping in the outermost edge slightly as shown at, 27, the cleaning pad can be very effectively held in position. The construction of the plate 23 is such as to provide a relatively large distributing chamber 28 between the flat top of the cap 17 and-the pad 25 which serves to distribute the cleaning fluid, as will appear below in connection with a description of the manner in which the device is used. The cap 17 and the backing plate 23 may be secured together in any desired manner, as by welding shown at 29.

The lower portion of the neck of the bottle is provided with the threads 30 over which is screwed the cover member 31, the latter serving as a means for keeping the device in clean con-. dition when not in use.

After the bottle is filled with the cleaning fluid the cleaning cap or closure member is placed in position with the indents 19 fitting into the vertical recesses or

grooves

13, 13a. Then, by rotating the cap in the direction of the arrow 32 in Fig. 6, the opening 22 in the cork gasket 20 will be brought to the dot and dash position shown at 22c. In this position the indents 19 have passed under the right hand cams 14 which serve to hold the cap in tight position against the top of the bottle so as to seal the opening 11. By turning the cap 19 in the direction of the arrow 33 in Fig. 6 the opening 2 2 can be brought to the dot and dash position 22b where it will register with the opening 11 in the web 10 of the bottle. During this motion the indents 19 engage the under surface of the left hand cams 15,

' and when the openings 22 and 11 are in registry the gasket 20 is tightly pressed against the top of the bottle in order to prevent leakage laterally between the cap and the top web of the bottle, egress of fluid during a cleaning operation, taking place, of course, through the

openings

11, 22 and 21.

When the bottle is inverted for a cleaning operation the fluid enters the distributing chamber 28 from which it passes through the perforations 24 into the cleaning pad 25. A gentle rubbing motion will serve to scatter the cleansing fluid as it enters the chamber 28 so that it will be substantially uniformly distributed throughout the cleaning pad.

Fig. 2 shows the cap withthe indents 19 in the

vertical channels

13, 13a, and in this position the side wall or skirt 18 of the cap may be crimped in at the sides intermediate the indents 19 as indicated at 34. The crimped portions 34 will extend beneath the shoulder 12. It will be seen, therefore, that once the cap has been applied it is non-removable and the bottle is non-refillable unless, of course, the cap is mutilated and its usefulness impaired.
