May 7, 1952 J. TORRES VELIZ SEAL FOR NONREFILLABLE BOTTLES Filed Dec. 29, 1949 Patented May 27, 1952 UNITED STATES PATENT OFFICE SEAL FOR NONREFILLABLE BOTTLES J os Torres Vliz, Habana, Cuba Application December 29, 1949, Serial No. 135,632

2 Claims. 1

The object of the invention is to provide a seal that effectively renders non-refillable the bottles to which it is applied, being constituted by an assembly of elements simply built and easily adapted.

More objects and advantages of the invention will become apparent in the course of this specification in connection with the accompanied drawings in which the same characters of reference indicate the same parts in all. the views.

In the drawings:

Figure 1 is a sectional, vertical, axial view showing the object of the invention in sealing position.

Figure 2- is a view similar to Figure l but showing the object of the invention in open position, that is, discharging the liquid contained in the bottle.

Figure 3' is a sectional, vertical, axial view showing the element of guide and seat of the valve and the valve itself seated thereon, that is, in sealing position.

Figure 4 shows the same elements of Figure 3 in an inverted position, the valve then being open.

Figure 5 is a detailed view of the excentric retainer of the valve.

Figure 6 is a plan upper view of the cover of the object of this invention.

Figure '7 is a side view of the cover represented in Figure 6.

Figure 8 is a plan lower view of the cover represented in Figures 6 and '7.

Figure 9 is a plan upper view of an element of the object of this invention.

Figure 10 is a side view of the element shown in Figure 9.

Figure 11 is a plan lower view of the element shown in Figures 9 and 10.

Figure 12 is a plan upper view of the element of guide and seat of the valve object of this invention.

Figure 13 is a side view of the element shown in Figure 12.

Figure 14 is a plan lower view of the element shown in Figures 12 and 13,

Figure 15 is a plan upper view of the valve object of this invention.

Figure 16 is a side view of the valve shown in Figure 15.

Figure 17 is a plan lower view of the valve shown in Figures 15 and 16; and

Figure 18 is a view of a floating element of the object of this invention.

Referring to the drawings, by A is indicated the neck of a bottle. A tubular body 1 showing a flange 2 is inserted in neck A, seating flange 2 on the mouth of neck A by means of the washer 3. The upper: face of flange 2 is provided with a circular groove 4 separating the concentric rings 5 and 6. The ring 5- shows radial nerves I. A valveconstitutedby a stem formed by spaced elements 8 and a head 9" is slidably mounted on tubular body I. Head 9, which upper face is finished in diamond points l ll seats on ring 6'. An eccentric l l loosely rotates around horizontal axis l2 which forms by one end a whole with tubular body I. A cross member l3 joins the free ends of two spaced alternate elements 8. A cover l4 provided with an outlet opening l'5 rests by its lower part on ring 5 of flange 2 and on washer 3. A bushing I6 inviolably secures the joint of cover M to neck A. On ring 5: of flange 2 encased under cover 14, rests a body formed by a disk I! of smaller diameter than the inner diameter of cover 14 on which periphery are spacedly affixed the elements [8 in which the cross section decreases toward the free end, forming in a whole, innerly, a conic surface. Disk ll that shows on its lower face spherical projecting portions I9 is placed at a lower level to that of joint ends of the elements l8 to disk H. A small sphere of floating material 20 is loosely encased among elements l8, surface I0 and lower face of disk [1.

The object of this invention works in the following way: Once the seal is applied to the bottle, to extract the contents thereof, when the bottle is inverted the valve will slide in the tubular body, the eccentric ll taking the position shown in Figure 4 and surface In of head 9 will contact sphere 20 that will be lying on the projecting spheric portions l9 of the disk [1. The bottle being thus placed, the liquid will flow out passing among the spaced elements 8 of the valve stem, between head 9 and its seat ring 6 of the tubular 7 body I, among the elements [8 and, finally, after passing between disk H and the inner upper surface of cover [4, through opening I5. When the bottle is again placed in its normal position, head 9 of the valve will again seat on ring 6 of tubular body I and the small sphere 20 will rest on surface In of head 9. The surface finished in diamond points [0 of head 9 of the valve, as well as the projecting spheric portions 19 on lower face of disk I! are provided to avoid the attachment of small sphere 20 to head 9 of the valve as well as to lower face of disk II.

If it is attempted to refill the bottle in an inverted position, the small sphere 20 will float in the liquid that is being tried to be introduced and, upon contact with surface of head 9 of the valve, it will force the latter to ascend until head 9 seats on ring 6 of tubular body I consequently closing the entrance of liquid. If it were attempted to refill the bottle by placing it in horizontal position, small sphere 20, which cannot remain attached to disk 11 due to the existence of projecting spheric portions l9, would roll over spaced elements l8 toward head 9 of the valve inasmuch as the inner outline of the assembly of such elements 18 determines a conic frustum surface with its major basis in that direction. Then small sphere 20 will rest on surface 10 of said head 9 keeping it seated on ring 6 of tubular body I whereby the passage of the liquid will be closed, thus making it consequently impossible to refill the bottle. The bottle being in its normal position it-could not be refilled by making the valve ascend by suction, for instance, because in that case the eccentric ll takes the position indicated in Figures 1 and 3, and the cross member 13 on contacting said eccentric ll precludes the ascending movement of the valve, its head 9 remaining seated on ring 6 of tubular body 1.

Having thus described the invention and the way in which it works, it is evident that difierent modifications can be introduced without departing from the substantial idea thereof which is what is comprised within the scope of the following claims.

I claim:

1. A seal for non-refillable bottles comprising a hollow cylindrical body having an outlet at one end thereof, a tubular valve guide having a radial flange abutting against the other end of the body, the guide extending from the body, a valve member slidable in said guide and adapted to seat on the inner periphery of the flange, a cage member mounted on the flange around the valve seat and extending toward the body outlet,

said member comprising a disk portion and a plurality of circumferentially spaced legs supporting the disk portion on the flange, the legs being tapered away from the disk to define an inner frusto-conical space between the disk portion, the valve and the legs, a sphere of buoyant material loosely enclosed within the frusto-conical space, and inviolable means for connecting the body to a bottle-neck with the guide extending inside the neck.

2. In a seal as claimed in claim 1, a valve member comprising a disk portion adapted to seat on the guide flange, a plurality of longitudinal stems spaced circumferentially around the disk and slidable on the interior surface of the tubular guide, and a transverse member connected to the free ends of a pair of diametrically opposed legs, and a valve locking member comprising a transverse pin extending diametrically across the guide between the valve legs at an angle to the transverse member and an eccentric loosely mounted for rotation on the transverse pin and having a rise extending into the path of movement of the transverse member toward open position of the valve.
