NONREFILLABLE BOTTLE Filed April 1, 1956 Inventor Patented Feb. 9, 1937 UNITED STATES OFFICE NONREFILLABLE BOTTLE Richard J. Watts, Quincy, Mass.

Application April 1, 1936, Serial No. 72,156

3 Claims.

My invention relates generally to a non-refillable bottle, and praticularly to such a bottle in which the member which prevents the refilling may be like the bottle made of glass, and an im- 5 portant object of the invention is to provide an 1, Figure l isa general transverse vertical sectional view taken through the upper part of the bottle showing the refilling preventing means in position in the neck thereof.

Figure 2 is a transverse vertical sectional view taken through part of the preventing means, and showing one section in an intermediate position with respect to the other section, the said position being the position in which these elements are inserted into the bottle neck.

30 Figure 3 is an elevational View of the of one of these sections.

Figure 4 is a perspective view showing the radially inward side of the left hand section.

Figure 5 is a perspective view showing the radi- 5 ally inward side of the right hand section.

Figure 6 is a perspective view of the section locking member. l

Referring in detail to the drawing, the numeral 5 generally designates the embodiment which comprises a bottle body 6 having thereon the upwardly tapered neck 1 which has a constricted portion 8 where it joins the top of the bottle body to form an opening for passage of the liquid from the bottle body to the bottle neck and has a rest for the gravity operated stopper 9 which is below the sections forming the filling preventing means which is generally designated l0 and which operates in conjunction with the stopper 9.

The stopper 9 comprises the flanged head I!) arranged to arrest on the annular shoulder formed by the constricted portion 8 to normally close communication between the body of the bottle and the neck of the bottle, from which head depends the tapered reduced diameter portion H which terminates in the enlarged diameter lower outer side portion i2 which is weighted in some suitable manner to efficiently take advantage of the force of gravity for positioning and holding the stopper 9 in the initial position shown in Figure 1.

The bottle neck F has an upwardly tapering '5 bore l3 which has a uniformly cylindrical upper part M of conventional diameter and arranged to receive a conventional stopper or cork S5.

The refilling preventing means which is generally designated i0 comprises the left hand sec- 10 tion and the right hand section I! (as shown in the drawing) each of these sections being generally semi-circular in cross-section and generally semi-cylindrical in formwith a flat top l8, l9 and a curvedly tapered bottom 20, 2! having 15 a conforming semi-circular axial recess 22, 23 therein.

In the left hand section it and above the recess 22 is the rectangular opening 2 3 which has the inclined floor 25 and. the horizontal ceiling 26. At about the middle height of the inner flat side 2'! of the left hand section 85 and immediately above the opening 24 is the opening 28 which includes the declining floor 29 whose upper end terminates radially outwardly of the floor of 5 the opening 2 3, as made clear in Figure 2. Merging into the upper part of the opening 28 is the reduced opening 30 which has the horizontal top 3! and the convex radially outward wall 32.

The flat radially inward side 33 of the right 0 hand section H has below the middle height thereof the radially inwardly projecting lug 34 which has the radially outwardly decliningunder face 35 the fiat horizontal top 36 and the upwardly and radially outwardly curved wall 31 which lies 5 within the sides of the generally rectangular opening 38 which is positioned approximately at the middle height of the. section I! and receives and operates upon the loose locking element 39.

The radially outward side of each of the sec- 40 tions has intersecting spiral grooves 40 and 4| which terminate at opposite sides of the section in the twin channels 42 and 43 which open laterally into each other on opposite sides of the dividing point 44. The grooves 40 and 4| open 45 at their upper ends as indicated by the numerals 44 and 45, through the top of the sections.

To place the refilling preventing means in in position in the bottle neck I, the locking element 39 is placed in the opening 38 in the right hand section I! and then the sections are brought together so that the under face 35 of the lug 34 and the inclined floor 25 of the opening 24 are in the superposed relation shown in Figure 2, in which arrangement of the sections their flat faces 21 and 33, respectively, abut or approximately abut so that the smallest possible diameter of the means It] is achieved, such that the means l0 may pass through the portion M of the bottle neck and into the tapered portion l3.

As the means l0 passes the portion l4 and arrives into the flared portion l3, the sections are permitted to separate in the manner indicated in Figure l, the section l1 moving gradually downwardly as the means 10 moves toward its lowest position until the locking element 39 is permitted to fall and go into position below the locking tongue 46 defined by the openings 24 and 28 to assume the position shown in Figure 1 after the right hand section I? has arrived on a level with the section l6 as the result of pushing the section I! downwardly relative to the section I6; so that the sections are then spaced a maximum amount at their lower ends so as to conform to the walls of the tapered portion l3 of the bottle neck, by which arrangement of the sections it becomes impossible without breaking a portion of the bottle to withdraw the sections through the neck. It is to be observed that the recess portions 22 and 23 at the bottom of the sections are arranged to permit a certain amount of vertical movement of the stopper 9 which takes place when the bottle is tilted, so as to open the restricted part below the bottle neck and permit passage of the fluid from the bottle body 6 into the neck and cause the fluid to pass through the various channels described and out of the bottle neck in the usual manner.

As indicated in Figure 6 the locking element 39 is in the form of a comma in side elevation and has a generally rectangular cross-section and is of a size and cross-section to rather closely conform to the correspondingly shaped opening 38 and the curved wall 3'! and rest on the flat top 36 of the lug and operatively fit in the upper part of theopening 30 in reaching a position by manipulation in the'manner described to engage its curved surface 4! under the locking tongue 46 in the left hand section l6.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the materials, and in the structure and arrangement of the parts, with the spirit of the invention and the scope of the subjoined claims.

What is claimed is:-

1. A non-refillable bottle of the character described comprising a body and a neck, a constricted portion between the body and the neck and defining a restricted opening, said neck havinga tapered bore, and a sectional refilling preventing means disposed in said tapered bore, the sections being arranged to be juxtaposed for insertion into the smaller upper part of the bore of the neck, interfitting tongues and recesses on the opposed wall of said section and having inclined faces to ride past each other in one direction and a free locking member also seated in one of the recesses and operating between said sections for spreading the lower parts of the sections away from each other as said sections are moved into the wider lower part of the said tapered bore, whereby removal of the sections through the smaller upper part of the bore is positively preeluded.

'2. A non-refillable bottle of the character described comprising a body and a neck, a constricted portion between the body and the neck defining a restricted opening, said neck having a tapered bore, and a sectional refilling preventing means disposed in said tapered bore, the sections being arranged to be juxtaposed for insertion into the smaller upper part of the bore of the neck,-interfitting tongues and recesses on the opposed wall of said section and having inclined faces to ride past each other in one direction and a free'locking member also seated in one ofthe recesses and operating between said sections for spreading the lower parts of the sections away from each other as said sections are moved into the wider lower part of the said tapered bore, whereby removal of the sections through the smaller upper part of the bore is positively precluded, and a gravity stopper having a flanged head resting on said restricted opening and immediately below said sections.

3. A non-refillable bottle of the character described comprising a body and a neck, a constricted portion between the body and the neck defining a restricted opening, said neck having a tapered bore, and a sectional refilling preventing means disposed in said tapered bore, the sections being arranged to be juxtaposed for insertion into the smaller upper part of the bore of the neck, interfitting tongues and recesses on the opposed wall of said section and having inclined faces to ride past each other in one direction and a free locking member also seated in one of the recesses and operating between said sections for spreading the lower parts of the sections away from each other as said sections are moved into the wider lower part of the said tapered bore, whereby removal of the sections through the smaller upper part of the bore is positively precluded, and a gravity stopper having a flanged head resting on said restricted opening and immediately below said sections, the radially outward sides of said sections having fluid conveying grooves opening through the top thereof and having their lower ends in communication with said restricted opening.
