Our preselltfinvention relates to the art'of bottling accessories and more particularly to a sediment collectingcap which is intended for use onbeyerage bottles of the effervescent type.

"The general purpose of our present invention is similar to that shown inour co-pending application, Serial No. 286,625, filed June 19, 1928. fMany sediment collecting devices have been created but most of them have the inherent fault of being difiicult to clean. Others have small valve members, upon Whose action little; dependence can be placed. In our presentcase we believe We have overcome the outstanding disadvantages indicated and d at the same time are ableto produce a bottlecap which clamps securely to the bottle, which can be made cheaply and be used over and over again without fear of any L damage.

Therefore, 1 7 v v object of our present inventionis to provide a simple bottle cap which will collect and retain'sediment precipitated by beverages. c W Afurtherobjectis toproduce a sediment collecting cap that may be easilycleaned;

Other and more specific objects will be apparent from the following description taken in connection with the accompanying drawings, wherein 00 Figure 1 is an elevation partly in section, showing our sediment collecting cap secured to'abeverage bottle. V

Figure 4 is a fragmentary sectional view :through onrbottle cap in the position in hieh it is to oatchsediment precipi-- tated;

shape of chamber 12'is a matter of preference. "It has been found desirableto have the. generalshape cylindrical, although for ease in manufactureit is usually more convenient ,to have it slightly coned with the small end at the closed end of chamber 12. This is a manufacturing expediency and gives draft for theeasy removal of cores which are used The end wall 24 of chamber 12 should preferably beflat and normalto the axisiof the bottle when the cap is in place. I This is desirable in order thatthe bottles maybe easily stoodupside down, it being necessary to so place the bottles in order that the sediment will filter downwardly and come to rest withfin, chamber 12.

. Normally disposed, partially within the bottle B and-partially withinthe cavity 12 is a valve member 30. This consists of'a stem- 32 upon which .is mounted a valve 34. It is so believed apparent that valve 34 might be 3 formed as a part of stem 32. However, owing to the variation in bottles it is often more desirable to have this valve formed sothatit snugly encircles stem 32 and in this manner should be up as high as will permit of a free how of the sediment past it, orrather, between it andthe bottle. This of course ,is

with the aim of providing the maximum available storage space in chamber 12 for the sediment. It has further been founddesirable to form the lower end of stem '32 as a iball 36 This member might be. dispensed with. a I

However, referring to Figure 1, itis believed apparent that if no ball 36' were provided the stem 32 would lie in close contact with the inner surface of the bottle neck and seals the same.

would thus form a natural lodging place for any sediment flowing downwardly. The ball shape of course could be easily changed to a conical shape with the point uppermost, as viewed in Figures 1 and 4.

Method of operation In operating our device it isusual to fill bottle B with the desired fluid up to the usual level. Valve member 30 is then placed in position as indicated in Figure 3. The cap proper i is then grasped in the hand and the mouth of the bottle entered into the coned portion 16. By applying downward pressure and twisting the cap slightly, it will-be found to go on very easily. It has been found, however, that it willTengage moreeasily and smoothly if thecapsare soaked in water for a few minutes, or at least are thoroughly wet. The water in this case acts as an excellent lubricant, preventing any frictional engagement between the glass and the rubber cap. The beverage bottle with the cap thus attached is then inverted as indicated in Figure 4. 7 Valve member 30, due toits own weight, dropsdownwardly until the end of stem 32 engages the bottom wall 24 of the cap. This spaces the valve 34 at the proper distance both from the bottle itself and from the bottom of the cap. The bottle is allowed to stand in this manner until all the sediment has been precipitated. Ordinarily, little,if any, will lodge on the sloping surface l0 of the valve. In some instances, however, this may occur. This condition may be remedied, however, by inclining the bottle about as indicated in. Figure 1 and. slowly revolving it for a turn or two. This is normally sufficient to dislodge any sediment which may have come to rest onsurface or. eveuon the upper surface of ball 36. The beverage should then be replaced to the positi'on shown'in Figure 4: until it is certain that all sediment has been precipitated. The bottle may then be inverted to the position indicated in Figure 3. The valve member 30 will drop downwardly until valve 34 engages the upper surface of the bottle mouth and Now normally the bottle will not be inverteduntil just before its content is .to be used, but itis possible to invert the same at anytime after the sediment has all been precipitated.

To. open the bottle,.bo'dy 10 is graspedby the hand and with a slightly twisting effort the cap is bent over to one side until it is entirely removed. -'lhis,operation is normally best performed over some vessel, as it is very desirable to keep the bottle substantially upright and it usually entails, of course, the spilling of the contents of chamber 12. The

valve member 30, however, has been found to adequately protect the open mouth of the bottle, even. though it iirsoine cases maybe removed from the bottle by being engaged by groove 14., as has been indicated in Figure 2.

The foregoing description and the accompanying drawings are believed to clearly disclose a preferred embodiment of our invention but it will be understood that this disclosure is merely illustrative and that such changes in the invention'may be made as are fairly within the scope and spirit of the following claims:

A sediment collecting cap consisting of a body portion formed of resilient material and adapted to provide a sediment collecting chamber; an annular groove, disposed near the open end of said chamber, adapted to ena bottle head; a valve assembly. having a coned valve adapted to engage the mouth of a bottle and a valve stem both disposed within said chamber and adapted to space said valve away from the end of said chamber. V
