NONREFILLABLE BOTTLE Filed Sept. 1'7 1936 2 Sheets-Sheet 1 In ven for ZlZfiiif/JWIZ iiorne ys May 11, 1937. J. A. PATTERSON NONREFILLABLE BOTTLE 2 Sheets-Sheet? Filed Sept. 17, 1936 M Attorneys Patented May 1 1 1937 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to non-refillable bottles and more particularly to non-refillable bottles of the type shown in my co-pending applications for patents respectively identified as patent application Serial No. 59,984, filed January 20, 1936, and Serial No. 66,903, filed March 3, 1936, each application being entitled Non-refillable bottle.

The present invention has particular reference to an improved valve structure for non-refillable bottles and more particularly for non-refillable bottles involving generally the structural features of those bottles disclosed, illustrated and claimed in my aforementioned and above identified applications for patents.

The present invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings where- Figure l is an enlarged vertical sectional view through the neck portion and associated parts of a non-refillable bottle involving the features of the present invention.

Figure 2 is an elevational view of a valve forming part of the invention.

Figure 3 is a bottom plan view of the valve assembly shown in Figure 2.

Figures 4, 5 and 6 are detail sectional views taken substantially on the lines 4-4, 5 5, and 66 respectively of Figure 1.

Figure 7 is a sectional view through a slightly modified form of valve.

Figure 8 is an elevational view of the valve assembly shown in section in Figure '7.

Figure 9 is a bottom plan view of the second form of valve assembly.

Referring to the drawings by reference numerals it will be seen that 5 indicates a fragmentary portion .of a bottle having a neck 6.

An elongated tube 8 formed of glass or other suitable material has an end portion fitting snugly within the bore of the bottle neck 8, and adjacent the lower ends thereof tube 8 arid neck 6 are complementarily grooved as at 9, l respectively to accommodate a split locking ring H which serves to lock neck 6 and tube 8 against longitudinal separation.

At the inner end thereof the neck 6 is provided with a shoulder [2 between which and the lower end of the tube 8 is confined a gasket I3 of suitable material.

Intermediate its ends tube 8 is provided with threads I4 complemental to internal threads l provided adjacent the upper end of the neck 6 whereby to effect a screw-threaded engagement of neck 6 and tube 8.

Disposed between the wall of the neck 6 and the tube 8 immediately above the threads l4, I5 is a gasket 48.

Thetube 8 above the threaded section thereof is also formed with a shoulder I! that has integral therewith a skirt I 8 snugly receiving the neck 6 :of the bottle as shown. Adjacent the lower ends thereof neck 6 and skirt l8 are provided with mating grooves 19 and 20 respectively to accommodate a locking ring 2| which serves as a further medium for preventing axial separation of the bottleneck and the tube 8.

At its upper end tube 8 is provided externally with threads 22 to receive a screw cap or the like, and at said upper end tube 8 is also bored as at 2.3 to receive a cork or the like.

At the inner end of the cork-receiving section 23 of the bore tube 8 is formed integrally with an internal disk 24 perforated as at 25 and as best shown in Figure 1.

To prevent relative rotation between the bottle and the parts just described and associated with the neck of the bottle, I provide a locking means in the form, preferably of ratchet teeth 26 provided on the internal surface .of shoulder l1 and with which cooperates a spring-pressed dog 21 suitably accommodated as at 28 within the wall of the bottle neck -6 adjacent the upper end of the neck.

The invention as above described is more fully disclosed in my above identified application for patent Serial No. 59,984.

.As stated in the statement of invention the 3 present invention is particularly concerned with a valve assembly for a bottle having the features of construction above disclosed.

In the preferred embodiment thereof the valve assembly consists of a substantially cylindrical cage 2.9 which fits within the upper end of the tube 8 in abutting relation with the disk 24.

The cage 29 intermediate its respective ends is circumferentially reduced to provide a suitable air space between the peripheral wall of the cage and the wall of the tube .8.

Inwardly from its upper end cage 29 is also provided with threads or otherwise to remova-bly and securely accommodate therein a disk or wall plate 30 having in alignment with the solid center portion of the disk 24 a passage 32.

Adjacent its bottom end the cage 2-8 is provided with a valve seat 33 and below the valve seat with a valve stem guide 34.

. ,Alsoat its lower end the cage 29 is externally threaded and is adapted to have screw-threaded thereon one end of a valve casing 35.

Valve casing 35 is substantially cylindrical and at its lower end the valve casing 35 and the tube 8 are complementarily grooved as at 36 and 3'! respectively to receive a split locking ring 38 which serves to removably secure the valve assembly within the tube 8.

Also threaded into the lower end of the valve casing 35 is a valve seat 39 provided with a valve stem guide 40.

Working through the valve stem guides 34 and 45 is a valve stem 4! that at its upper end is formed with an integral disk valve 42 engageable with the valve seat 33.

The valve 42 is yieldably engaged with the seat 33 through the mediiun of a coil spring 43 housed within the cage 23 and at one disposed about a flange 44 provided at the inner end of the opening or port 32 while at its lower end the spring 43 seats on a metal washer 45 confined between the enlarged head of a screw 46 threaded into the stem 4! and a disk 87 of rubber or other suitable material interposed between the washer 45 and the valve disk 42. Thus it will be seen that valve 4?. normally closes com.- munication between the valve casing 35 and the cage 29.

Working within the valve cage 35 is an elongated hollow float cylinder 4? that at one end is secured to the stem 4! as at 48. At its lower end or bottom the float cylinder 4? is formed as at 49 to present a valve adapted to engage the seat 33 for closing communication between the bottle and the valve casing 35.

For vent purposes and to relieve vacuum the peripheral walls of the float cylinder 41 and the valve casing 35, exteriorly of the float 4i and internally of the casing 35 are oomplementarily grooved or ribbed as at 50, 5i. (See Figure 6.)

From the description of the invention thus far it will be seen that with the bottle in an upright position the parts will assume the position shown in Figure 1 which will preclude a refilling of the bottle.

To pour the contents, or a portion thereof from.

the bottle 5, the latter is inverted. In this inverted position the pressure of the contents of the bottle on the end 33 of the member 41 will cause said end 39 to unseat as also the valve 33 against the action of spring 43. Thus the liquid will flow through the valve casing 35 to cage 29 through the port 32 to discharge from the bottle through the perforations 25.

Immediately upon the bottle being brought to an upright position end 49 of the member 41 will seat as will also the valve 33 thus closing the bottle. Thus it will be seen that after all the contents of the bottle have been emptied therefrom it will be impossible to refill the bottle.

In theform of valve assembly shown in Figures '7 to 9 inclusive, there is embodied a cage 29*, a valve casing 35*, a threaded connection between cage 29 and 35 as indicated generally at 52, a disk 39 threaded in the bottom end of the casing 35*, a valve stem M a float cylinder 41 and a valve seating spring 43 However, in this form of the invention the disk 3F- provided inwardly from the upper end of the cage 23 is provided with a series of perforations 52.

Also, in this form of the invention the valve casing 35 is provided at its upper end with an integral end wall 53 from which rises an integral socketed boss 54 having a conical internal wall structure as shown. Also threaded into or spun into the upper end of the socket 54 is a disk 55 between which and a frusto-conical valve member 55 working in the socket 54 is interposed the aforementioned spring 13 which serves to cause the valve member 55 to suitably seat in the lower end of the socket 54. Adjacent said lower end the socket 54 is provided with lateral ports 5! which are closed by the valve element 53 when the latter is in the fully seated or lowered position as shown in Figure '7.

Also in this form of the invention the member M which at its upper end is secured to the stem M as at 48 is provided with perforations 58 while the member W at its bottom is entirely open as shown.

Also the seat member 39 is in the form of a disk threaded into the lower end of the casing 35 and provided at its center with an enlarged opening having a conical flange 59 rising therefrom to extend into and through the open end of the member 41*. Also the member 39 is provided with a valve stem guide 50 through which the valve stem di works as shown.

It will be seen from the above that with this type of valve employed in the bottle the contents of the bottle, when the bottle is inverted, will pass from the bottle proper through the opening in the disk 35 and into the member ll and the pressure of the liquid within the member il will cause the valve 55 to move against the action of spring 43 to uncover or open the ports 51. Thus the contents will flow through the openings 53 and the ports 5? into the cage 23 to discharge through the perforations 52. When the bottle is set upright the parts under action of spring 43 will return to the normal position which is the position shown in Figure '7 in a manner to securely close the bottle and to preclude the filling of the bottle.

It is thought that a clear understanding of the construction, utility and advantages of an invention of this character will be had without a more detailed description and that further, it will be appreciated that a bottle having a valve construction as anticipated by this invention will be particularly useful in bottling alcoholic beverages and the like under such laws and regulations as prohibit re-use or refilling of the bottle.
