NONRE'FILLABLE BOTTLE Application filed August 3, 1929. Serial No. 383,372.

The object of this invention is the provision of a bottle neck construction and means there-v in which will permit of the fluid contents of the bottle being freely poured therefrom, but a which, after the contents'have been poured therefrom will positively prevent the refilling of the bottle by any means or regardless of any angle which the bottle is caused to assume.

To the attainment of the foregoing the invention consists in the improvement hereinafter described and definitely claimed.

' Figure 9 is a similar view showing the arrangement of parts when the valve has moved in to lock the same between its seat and cap.

Before proceeding with a detailed description of the improvement I desire to have it understood that the construction of the component parts constituting the invention requires no departure from the present day glass manufacturing methods. The bottle can he hlown in the usual-manner by simply adding a neck-mold to the blow pipe. The other component parts can be readily blown or molded from glass. The only increase in cost would be that necessary in making the original molds, (which would be negligible in the end considering the number that could be produced from one mold), and the additional small amount of glass necessary to make the parts. It will be noted as the description progresses that no complicated work will be involved in inserting the parts and the cap ing of the bottle, as there is no matching 0 the parts requirin painstaking hand operations before or during the insertion thereof and the capping of the bottle. Also in this connection it may be well to state that bottling machinery can be adapted to the handling of the improvement for a quantity production basis which is essential in cutting down the production costs.

In the drawings I have not deemed it necessary to illustrate a complete bottle, but the neck 1 thereof is blown in three steps to accommodate the inserted parts. The first step which comprises a flat seat to contact with the under face of the valve which will presently be described. The seat is surrounded by a groove 2, and the inner wall of this groove is cut at an inward angle. The second step 3, which is slightlyabove the step or valve seat 1 accommodates the cap 4: which is arranged directly over the valve and the third step 5 accommodates the sealing lug 6. Above the step 5 the neck of the bottle is formed with an annular groove 7 for. the reception of a split spring wire or member 8 received in the peripheral groove in the sealing plug 4 which expands and enters the said groove 7 for holding the sealing valve in the bottle neck. In

addition to this the sealing plug has an upper peripheral groove for the reception of a packing 8 and a lower annular groove for the reception of a packing 9 that rests directly on the step or shoulder 5.

The valve 10 is in the nature of a flat disc .with a rojecting lug 11 that is equal tothe circum erential measurement of two fins 12 formed on the periphery of the cap 4. The lower or bottom face of the valve 10 is flat so that the same will effectively rest on the seat 1. The valve is of such diameter in relation to the seat 1 as to cover the said seat in any position of its free movement under the cap 4 and within the annular groove or depression between the valve seat and the shoulder 3, which space affords a guide race for the valve. On aline through the center of the disc valve 10 and the projecting lug 11 there is formed on the under face of the said valve a stem 12. This stein has on its outer end a ball head 13 ,to weight the said stem. The stem is of a form bevel 14 so that the valve is held tight (ill under the fins 12 of the cap 4.

The valve ap 4 is cylindrical in shape and, as stated, ha its outer periphery fluted to allow passage of the bottled contents. The top surface of the valve cap has an upstanding annular lip 15 to prevent the insertion of any article through the sealing plug 6 which otherwise might pass through the sealing plug, through the flutes of the bottle to engage with the bottle for holding the latter open. The bottom of the flutes or fins 12 are flat for contacting with the step 3 in the bottle neck and also to act as retaining blocks for the valve 10. The valve cap serves as a guide and also a lock for the valve; 10. From its bottom the cap 4 is formed with a cup-like recess or depression 16, the bottom ofthe cap proper being disposed above the lower ends of the flutes 12 and the diameter of this recess or depression is such as to provide a clearance for the flapper action of the valve 10. The bottom surface of the fins 12 retains the lug of the valve under them and against'the wall 17 that provides the outer wall of the depression 2 and which I have referred to as the guideway. This contact of the lug 11 with the wall or guide race 17 allows the valve 10 to swing upwardly, on the fulcrum aifordedbetween the guide seat 1 and the depression 2 when the bottle is tilted to empty the contents therefrom. As long as the bottle is in correct position for em tying the valve 10 remains concentric with t 1e valve cap recess'and works freely. WVhen the bottle is empty and no weight is behind the valve the stem with its extended center of gravity causes the valve lug to engage one or two' fins and, through gravity action, the fins act as a block and the weight of the stem 12 and ball 13 exerts a downward pulling upon the valve '10 and keeps the said valve against its seat. This takes place in the proper emptying position. fr

The "alve stem being attached eccentric to the disc valve has a tendency to cause the said valve to move in the guide race to find its lowest point of gravity.

Figure 8 discloses the relation between the disc valve and the valve ca when the disc lug engages two fins while t e bottle is held with valve in proper emptying position. The disc valve is concentric with the fins of the valve cap and the disc lug is engaging fins on bottomto allow the lug 11 to serve as a fulcrum against the seat 1 so that the valve can enter the depression orrecess 16 to permit of the discharge of the contents of the bottle. However, should the valve not be opened, provision has been made to prevent the valve acting in any other position. The

disc valve can only enter the recess or depression 16 when the said valve is concentric with the said recess or depression. Should the edge of the valve disc touch the gmde race or. wall 17 atany point other than that engaged by the lug 11 the said disc loses its concentricity with the valve cap' recess and engages a number of fins that retain it in a closed position. This prevents gravity action of the stem and ball end of the valve from working in a reverse direction to open the valve. In this position the bottle cannot be filled and discharges its contents slowly, if at all, depending on the body of the contents. This is best illustrated by Figure 9 of the drawings which shows the disc valve in the extreme eccentric position with respect to the valve cap fins. This figure also shows the disc valve engaged by a number of fins to retain it in closed position. It is at this point. that the value of the beveled outer edge of thetop surface of the valve is seen and, it is thought appreciated. This beveled edge causes easy entrance of the valve under the finsat any position and also makes a snug fit under the fins by gravity pressure. The sealing plug 6 is provided with a central somewhat restricted outlet opening 18 arranged above the flange 15 on the cap and with an annular depression 19 upon its lower face in which the flange 15 of the cap is received, and there is a comparatively narrow passage between the said depression or recess 19 and the lip 15 of the cap. .It is also to be noted that the lower end of the sealing plug rests directly over the fins 12 of the cap and further that I employ no Wax or similar sealing means for sealing the plug in the bottle neck.

It will be noted from the above description when carefully read that I have produced a simple, cheaply constructed bottle construction which will freely permit of the passage of the fluid contents from the bottle but which will eflectively'and positively prevent the refilling of the bottle afterthe original contents have been poured thereom. It will be further noted that the parts constituting the improvement may be cheaply constructed in quantities and it is to be imderstood that while I have herein illustrated a satisfactory embodiment my features of inall vention are capable of extended application and I do not wish to be limited to the specific structure herein shown and described.

it is to be noted that the lower wall provided by the groove 7 for the packing or holding ring 8 is beveled or chamfered so that the expansible ring 8 can be fully received in the groove when the plug is inserted in the bottle neck and thereby materially facilitate such insertion of the plug. in addition to this any attempt to withdraw the plug from the bottle neck will cause the split holding ring 8 to travelover the inclined wall provided by the chamfer to further expand the same and to bring the said ring into tighter engagement with the groove provided in the bottle neck for the reception thereof.

l vhat is claimed is 1. A non-refillable bottle having a weightits seat in one angular direction when pressure is exerted thereagainst from the inside of the bottle and slidable to locked position beneath the cap when the bottle is canted.

2. A non-refillable bottle having a valve seat therein, a groove above the seat, a groove surrounding the seat and an outer shoulder,

a flat valve for the seat, said valve being cccentrically weighted and having a peripheral lug to contact with the outer wall provided by the groove, and the weighted portion of the valve being disposed adjacent to the lug, a valve cap having peripheral fins depending from the body thereof and which rest on the shoulder above the valve seat, and a centrally apertured plug fixed in the bottle neck and having an inner annular depression that receives therein the outer end of the valve cap,

as and for the urpose set forth.

3. A non-re llablebottle having a valve seat in the neck thereof, a groove surrounding the valve seat, a lower shoulder slightly above the valve seat, and an upper shoulder,

a disc valve normally resting on the seat and having a lug extending and contacting with the wall between the seat and groove, said valve having its under face formed with a stem that enters the bottle, and the outer end of the stem being weighted, the upper periphery of the valve being beveled, a'cap having peripheral fins extending from the bottom thereof which rest upon the lower shoulder and slightly out of contact with the valve, and two of the fins being disposed from the lug tension on the valve, said cap being recessed from its innerface to provide for the reception of the valve when the latter is u swung to open position, an angular flange on the upper shoulder, having side and lower angular grooves for the reception of packin'gs
