To all whom it may concern;

Be it known that I, HARRY BECKER, a citizen of the United States, residing at Hull, county of Plymouth, State of Massachusetts, have invented an'Improvement in Non-Refillable' Bottles, ofwhich the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representlng llke'parts.

This invention has reference to bottles of the type known as non-refillable bottles.

Such bottles are so constructed that it'is practically impossible or so difiicult to refill them that re-filling, would not beattempted commerciallyv by retail dealers.

Certain types of liquid are" sold by manufacturer to retail dealers in large 'supply. bottles and then re-sold in small quantities by the retailer to individual consumers.

It is an easy matter for dishonest retailers to I re-fill bottles bearing the name and trade:

mark of a well known manufacturer with cheap and inferior. substitutes thereby cheating the customer and damagingthe reputation ofthe manufacturer. For this reason there is a growing demand among manufacturers for non-refillable. bottles, that is,; bottles which there ailercannot re-fill commercially.

tion, thereby permitting the contents to be poured out but preventing the re-filling of the bottle. by the retailer. Another object'is to provide an improved bottle of this type having a movable valve.

and means to prevent the movement of the valve to open position'when the bottle is in anupright or substantially upright position. i

The object of this invention is to provide an improved bottle of thisv type having a; simple and cheaply constructed stopper which will automatically open when the bottle E is inverted. and automatically"closeand stay closed when the bottle is in any other posi- J taken on the line 3-3, Fig. 1; and Fig. ,4 is

a sectional view taken on the line 4l,"

,eferring to thedrawings in detail, the bottle which may be of any suitable or de--.'.i

parts in detail; Fig. 3 isa sectionalview 751 sired shape or size is indicated at land has I a long neck 2 preferably closed at its upper end by the usual cork crown seal or other removable closure, the former being illustrated ispositioned in theneck2 preferably close to the body of theibottle.- This stopper is so designed that it automatically-opens when the bottle is inverted,bnt closes and remains closed'whenthe bottleisin any otherposition, andalso{closesautomatically'if it be." a I .75 1 i attempted toforce the liquid, into the bottle under pressure.

The stopper illustrated comprises a. tubur lar member 4 having an upwardly presented valve seat 5 at its .upper end and a downwardly presented conical cam surface. 6 at its lower end, with a closing member consisting of a valv'e'stem 7 ,to the upper and I .at 3.v In accordance with my invention'a I;

non-removable stopper in the form of a valve lower. ends of which respectively are; Se-

cured a valve 8 and a weightv 9 with a fulcrum member 10. slidably and 'rotatably mounted therebetween. ,lilheweight 9 and the fulcrum member 10 are, in the preferred form, slidably mounted on the valve stem 7 and the'stem 7 is provided with ahead as indicated atll'in Fig. .2. In the preferred spindle that if anattemptbemadeto fill" the bottle by shaking it or, by giving it suddenjars the fulcrum member will move upwardly and become wedged upon theyvalve stemin position close tothe cam surface 6 and thereby preventmove'ment of thevalve upward away fromthe valve seat15 in response to such shaking. The stopperis done by securing thetubular member in the n Qk of the bottleby sealing materiall12;

Cork or similar material of an expansive nature, is j preferably employed for this pur- 7 ice permanently fixed in position, in the bottle,:; and --in the constructionillustrated this-is posevand the best results are secured by pro- I the bottle asito provide an annular recess 14 on the interior thereofl Thus when the viding grooves or recesses 13 on theperiph.-

cry of the tubular member 4 and so'shaping stopper and cork areforced into place the form also the valve stem :7, is tapered and them fulcrum member so fits upon this tapered the bottle has a downward taper in the section occupied by the cork or sealing material by which it is further compressed and a tight fit under all conditions. is insured.

The valve 8 is preferably of a generally conical shape so that it may the more readily be drawn to its seat when the bottle is returned to horizontal or upright position after pouring and it is preferably of spherical shape at that portion which engages the seat to insure a perfect fit in all angular positions of the valve stem. The fulcrum member is positioned between the valve and weight to cooperate with the cam surface when the bottle is in a generally horizontal position and slides thereon to draw the valve to the seat 5 and hold it thereagainst. It is of such a size that it cannot enter that part of the tubular member above the cam surface 6 and is of such a shape that it will not interfere .with the flow of liquid. This member is illustrated as having three radial fins 15 and centrally bored to receive the valve stem 7.

The tubular member 4 is provided with two upwardly extending members 16 diametrically opposite each other to provide support. for a pivotedlocking member 17. These upwardly extending members are illustrated as forming support also for a top plate or shield 18 which prevents access toithevalve, the sealing material and the bottle interior.

The pivoted lockingmember 17 is of a length to extend close to the valve 8 so that I when the bottle is in upright position and the locking member hanging downward upward movement of the valve by any means is impossible. In its preferred form this looking member is sector-shaped so that even if the bottle is tilted considerably to one side the locking member will still be in a position to prevent the unseating of the valve by engaging the center thereof and in the plane of its axis. The lower end of this member is thickened as indicated at 19 to increase its weight and-cause itto swing more freely. As

a convenient method of connecting the locking member to the supports 16 I secure a pivot pin 20 in the supports and provide collars 21 and 22 to retain the locking member in central position thereon and adapted to swing in the plane ofthe axis of the valve and valve stem.

' The shape of the valve as previously described is such that as'it bears against the valve seat when the bottle is laid in a horizontal position, the valve tends to move to open position by sliding along the valve seat. In order to counteract this tendency the weight is so proportioned and so spaced .ing to properly operate. Ample space is alfrom the bearing portion of the fulcrum member that it balances the Weight of the valve 8 as "the bottle is in horizontal position. By this expedient substan tially the whole weight of the closing member bears upon the cam surface, and hence slides down the cam surface to thereby draw the valve to its seat making it impossible to pour liquid into the bottle when in a horizontal position. Since the weight 9 is slidably mounted on the stem 7 the seating of the valve 8 is further insured. Any shaking or vibration given the bottle thus causes the valve and the weight to act successively forcing the valve to its seat to prevent any attempt surreptitiously to fill the bottle;

It will. thus be seen that the device embodying this invention is of exceedingly simple construction.

The device in its preferred form comprises but few parts the tubular member presenting a valve seat and cam surface, the valve with its valve stem, the weight, the fulcrum I member, the pivoted locking member and the 90 shield which is rigidly securedto the tubular member. The parts are so shaped and constructed that there is practically no liability of their getting out of order or faillowed for the liquid to be withdrawn from the bottle by pouring, and liquid of the greatest viscosity can readily be .thus poured.

The fulcrum member being freely revoluble and slidable on the valve stem acts automatically to clear the device of any sediment or slight'obstruction which may get through with the liquid. When the parts are inplace it is practically impossible to reach, injure or mutilatethem or'to remove them from the bottle. The parts are all concealed in the neck of the bottle so that the bottle presents the ordinary and usual appearance.

The several parts of the device may be made of any suitable material but obviously of such a material that they will'not impair or injure the contents. of the bottle or be themselves subjected to corrosion, preferably therefore these parts will be made of material platedor covered with tin, porcelain or the coating used on well known agate ware. The valve 8 proper may be made of other material, such as hard rubber' if desired, or when practicable. It is only necessary that there should be a close fit between. the valve and its seat.

The fulcrum member and weight may be considered broadly as two weights. Both weights are loosely mounted upon the valve stem. Accordingly, certain advantages are obtained, for example, when the bottle is given a' vibrating movement, the weights operate against each other and thereby tend toprevent the unseating of the valye.

Having thus described my inventlon what 0 I claim as new and desire to secure by Letters Patent is;

1. The combination with a bottle, ofa tubular member permanently secured in the neck of the bottle and having an upwardly presented valve seat and a downwardly presented cam surface,a closing member freely movable in said tubular member comprising a tapered valve stem, a valve securedthereto, a member slidably mounted onthe valve stem and positioned to engage the tapered portion of the valve stem to be wedged thereupon and a shield positioned in the neck of the bottle to prevent access to the parts.
