The rear edge portion 45 of the part 3! of the section 22 is arranged inwardly with respect to the outer face of such section and laterally disposed with respect to the part 33 of section 22. The stretches of the ribs snugly engage in the branches of the grooves. The edge portions 39 and 45 constitute inwardly arranged annular shoulders.

The part 29 is of less width than the part 30. The part 3! gradually decreases in width from its point of jointure with part 32 to its point of jointure with part 30. The major portion of the length of part 3! is less than the width of part 30 but greater than the width of part 29. The width of part 32 is less than that of the part 39. The width of part 33 is less than that of parts 30, 3! and 32.

Each section is formed lengthwise thereof with an outer cavity 43 of semi-circular cross-section which is arranged in a portion of part 30 and extends throughout part 3!. The cavity 46 is open at its rear end and closed at its forward end, as at 47. The cavity 46 consists of a portion 48 gradually decreasing in width to the closed end 4'! and a portion 49 of uniform width, of less length than and merging at its forward end into the rear end of the portion 48. Each section is formed lengthwise thereof with an inner cavity of semi-circular cross-section which is arranged completely in part 33. The cavity 50 is open at its rear end and partly closed at its forward end, as at 5!. The cavity 5!! consists of a portion 52 gradually decreasing in width to the closed end 5! and a portion 53 of uniform width, of less length than and merging at its forward end into the rear end of the portion-52. The cavity 53 is of less length than the part 33 and has its rear end flush with the rear end of part 33. The wall part of the-portion 490i the cavity 46 is formed with asemi circular groove 54. The wall part of the uniform portion 53 of the cavity each consists of an outer end branch 6! an inner end branch 62, an outer intermediate branch 63, a rear intermediate branch 34, and an inner intermediate branch 65. g The rear end of the branch 6! rnerges into the outer end of the branch 63. The rear end of the latter is closed. The rear end ofthe branch 64 is closed. The branch 65 establishes communication between the forward end of the branch 54and the branch 63 intermediate the ends of the latter. The branch 62 opens into the cavity 46 and establishes communication between the cavity intermediate its ends and between the branch 54 intermediate the ends of'the latter. The branch 5! at its forward end opens into the part 29. The branches 6!, 63 and a portion of the branch 64 are arranged in the part 30. The remaining portion of the branch 64 is arranged in the part 3!. The branch 62 is arranged in the parts 30 and 3!.

The branch 55 extends forwardly of the cavity 53 and merges into a rectangular recess 66 formed in the forward end of the part 33. The passages in crosssection are of curved contour. The closed ends of the branches 65 of the grooves 59, 60 extend rearwardly with respect to the branches 66 of the said grooves.

The part 38 of each section is formed centrally with a socket 67. The part 3! of each section in proximity to its rear end is formed with a pair of spaced aligning sockets B8, 69. The part 32 of each section in proximity to its rear end is formed with a pair of diametrically opposed lugs on its inner face.

The sections 2! and 22 are secured together in abutting relation by holdfast elements 7! of a form capable of engaging in the sections when said elements are in holdfast position. When the sections 2! and 22 are arranged in abutting relation, the mouth of the socket 67 of section 2! registers with the mouth of the socket 67 of section 22, the mouth of the socket 68 of section 2! registers with the mouth of the socket 6B of section 22, and the mouth of the socket 69 of section 2! registers with the mouth of the socket 69 of section 22. A holdfast element I! is mounted in each pair of aligning sockets, by way of example, as illustrated in Figure 2 for securing the sections in abutting relation. When the sections 2!, 22 are secured together, the ribs 25, 25 engage in the grooves 23, 24 respectively; the grooves 51 of the sections 2!, 22 register to form an outer tortuous tubular passage '!2 for fluid discharge andfor combined air intake and fluid discharge. The passage '!2 opens atits forward end into an outlet ?3 provided by the'inner faces of the parts 29 of the sections when said sections are in abutting relation. When the sections 2!, 22 are secured together, the grooves 58 of the sections 2!, 22 register to form an outer tortuous tubular passage 14 for fluid discharge and for combined air'intake and fluid discharge. The passage 14 opens at its forward end into the outlet 13. The latter is normally closed by a removable stopper 15. When 75,:

the sections 2!, 22 are secured together, the cavities 49 of said sections register to provide an outer valve chamber I6 for a globular valve 1'! and a resilient disc valve I8. When the sections 2|,

- 22 are in abutting relation, the cavities 59 thereof register to provide an inner valvechamber I9 for a ball valve 89 and a resilient disc valve 8! When the sections 2!, 22 are secured together, the; grooves 59 thereof register to form a rear tortuousvtubular passage'82 for conducting liquid and for conducting combined air and liquid. When sections 2!, 22 are connected together in abutting relation, the grooves 99 thereof register to provide a rear tortuous tubular passage 93 for conducting liquid and for conducting combined air and liquid. When the sections 2!, 22 are secured together in abutting relation, the recesses 99 of said sections register to provide a rectangular opening 96 into which the passages 82, 83 open. When the sections 2!, 22 are secured together in abutting relation, the semi-circular grooves 54 thereof register at their ends to form an annular forward groove. When the sections 2!, 22 are secured together in abutting relation, the rabbets 55 thereof register to form an annular rabbet and the semi-circular grooves 59 thereof register at their ends to form an annular rear groove. The part 33 of each section is formed with a semi-circular groove 84 and said grooves 94, when the sections are secured in abutting relation, register to form a tubular passage 95 (Figure 2) for establishing communication between the valve chamber I9 and the rectangular opening 59 provided by'the registering of the recesses 96 The rear ends of the channels I2, 19 open into the valve chamber T9 at the opposite sides thereof and intermediate its ends. The rear ends of the channels 82, 83 open into the valve chamber I9 at opposite sides thereof and intermediate its ends.

The attachment includes a forward and a rear combined valve seat and holding member 86, 81, respectively of circular form. The member 86 consists of a disc 88 which is mounted in the forward annular groove provided by the grooves 54 of the sections. The disc 88 has a central opening 89 which communicates with the opening 66 Integral with the upper face of the disc 88 is a series of upstanding equi-distant spaced lugs 99 positioned inwardly adjacent the edge of disc 83 and bearing against the uniform portions 49 of the cavities 99 formed in the sections 2!, 22. The lugs 99, in connection with the disc 98, form the member 99 of substantially cup-shaped contour. The lugs 99 are spaced outwardly adjacent to the edge of the wall of opening 89. The valve !9 is normally seated on the disc 88 between the lugs 99 and tends to normally close the opening 89. The valve '5'! is seated on the valve 18 and is freely movable within the valve chamber I9. The diameter of the valve 78 is less than the distance between the lugs 99.

The member 87 consists of a disc 9! formed with an opening 92 which communicates with the interior'of the bottle. The disc 9! is formed with a laterally disposed annular extension 93 which extends into the rear annular groove formed by the grooves 59 of the sections 2! and 22. The disc 9! abuts against the rabbets 55 of the sections 2! and 22. The intermediate portion of the disc 9! is of reduced thickness, as at 94, and upon which normally seats the valve 8!. Formed integral with disc 9! is a series of equi-distant spaced upstanding lugs 95 which abut against the uniform portions 53 of the recesses 59 in the sections 2! and 22. The diameter of the valve 8! is less than the distance between the lugs 95. The valve 89 seats on the valve 8! and. is freely movable in the valve chamber I9.

When the sections 2!, 22 are secured together by the holdfast means 1!, the parts 32 of said sections coact to form the attachment with an annular inner end which surrounds and is connected to the portion I4 of the neck by the coaction of the lugs I9 with the bayonet-shaped grooves I9. The edge portions 39 of the sections 2!, 22, when the attachment is coupled to the neck, seat upon the washer or gasket I8. Prior to the coupling of the attachment to the neck the portion I9 of the neck, as well as the shoulder I9, is coated with suitable cementitious material 93 for the purpose of fixedly and permanently securing the attachment to the bottle neck. When the sections 2!, 22 are secured together by the holdfast means II, the parts 33 of said sections are brought into abutting relation and provide an internal inner end part of circular cross-section which extends into and is disposed in concentric relation relative to the inner face of the neck of the container. The gasket I8 acts to seal the forward end of the space formed between the abutting parts 33 and the inner face of the container neck.

The ball valves are of like construction and each consists of a metallic cover section 97 and a solid metallic core section 98. The latter is of greater weight than that of the section 97.

The form shown in Figure 9 will include two like oppositely disposed interengaging sections (but one of said sections is shown) and designated generally at 99. These sections will be similar to the sections 2!, 22, with the exception that the outer grooves which coact to form the air intake and fluid discharge tortuous tubular passages will be of a different form with respect to the passages 51, 58, and that the inner grooves which coact to provide the air and fluid conducting tubular passages will be of a different form with respect to the passages 59, 99. The section 99 corresponds to section 2!. The other section, not shown, of the form illustrated by Figure 9, will correspond to section 22. The sections of the modification will be of like form, but with this exception, that one section will be provided with a pair of grooves similar to the grooves 23, 29 of section 2! and the other section thereof will be provided with a pair of ribs similar to the ribs 25, 29 of section 22. The description to follow with respect to section 99 is to be understood to apply to the section of the modification not shown.

The section 99 includes a pair of oppositely disposed outer grooves I 99, I9! of like form and each includes an outer side wall formed of a series of stretches in angular relation. The said outer wall includes a short rear end stretch I92 which at its outer end merges into the rear end of an inwardly extending upwardly inclined stretch I93. The latter merges at its outer end into the rear end of a straight stretch I94 of materially greater length than the stretches I92, I93. The stretch I94 merges at its outer end into the rear end of an inwardly extending upwardly inclined stretch I95 of greater length than stretch I93 and of less length than stretch I94. The stretch I95 at its outer end merges into the inner end of a laterally directed downwardly inclined stretch I95 of slightly less length than stretch I95. The lower end of stretch I96 merges into the rear end of an inwardly extending upwardly inclined stretch I9! of greater length than stretch I99.

length than stretch I97. The inclination of the latter is less than that of stretches I93, I05 and I98. The inclination of stretch I96 is less than that of stretch I95. The stretches I93, I95, I05. I 91 and I 98 are disposed at different angular relation with respect tothe lengthwise median of section 99. The stretches I92, I93 are disposed parallel to the longitudinal median of section 99. Each outer groove includes a rear end wall I09. Each outer groove also includes an inner side wall formed with an opening II I) forwardly of wall I99.

The opening III] communicates with the recess II I. The inner side wall of each outer passage is formed of an inner and an outer section. The inner section of the inner side wall consists of a short straight stretch I I2 extended forwardly from wall I99 and opposing in parallel spaced relation and of less length than stretch I 92. The rear and front walls of opening IIIl are indicated at II 3, IIG and they are disposed at upward inclinations. The stretch II2 at its outer end merges into the outer end of the wall H3. The outer section of the inner side wall includes a rear end stretch II 5 which extends inwardly at an upward inclination and at its rear end merges into the outer end of wall I I I. The stretch II5 at its outer end merges into the inner end of a laterally directed downwardly inclined stretch I I5 which at its outer end merges into the rear end of an inwardly extending upwardly inclined outer end stretch III. The outer end stretches III of the grooves I99, IIII merge into each other at their outer ends. The combined intake and outlet of each outer groove is designated H8. The stretch III opposes the stretch I 98 and a portion of stretch IIlI. The stretch I I6 opposes a portion of stretch I96. The stretch H5 opposes the stretch I05 and a part of stretch I94. The lower portion of the latter, the stretch I93 and a part of stretch I92 opposes the opening H9. The stretches I I5, I I6 and I II are disposed in different angular relations with respect to each other, and are also disposed in angular relation to the longitudinal median of section 99.

The inner grooves of section 99 are of like form, oppositely disposed, and indicated at II 9, I20. Each inner groove is formed in its inner side wall with an opening I2I which communicates with the recess I22. Each inner groove has its outer side wall I23 inclining upwardly from its rear to its forward end. Each inner groove has its inner side wall formed of a. rear and a front section I29, I25, respectively, each inclining inwardly from its rear to its forward end. The rear end of sec tion I29 merges into the outer end of the front wall I 23 of opening I2I. The forward end of section I25 merges into the outer end of the rear wall I 2? of opening I2I. Each inner groove includes a rear end wall I28 which merges into the rear ends of the side wall I23 and section I25. The wall I23 opposes the sections I23, I25 and intermediate its ends opposes the opening I2 I.

The modification of the invention shown by Figure resides solely in a different shape of the outer and inner grooves of each section of the attachment than that as shown in Figure 8. In Figure 10 the section I29 of the attachment which may correspond to sections 2I, 22 or 99, but-more particularly in contour to that of section 2I or 22,

has the outer grooves formed therein, indicatedindicated at I33, I34. The inner grooves of section I28 are of the same form as the inner grooves shown in Figure 9.

The outer grooves I3I I32 are of like form and are oppositely disposed. Each of the outer grooves in section I28 includes an outer side wall which is formed of a rear end stretch I 35 which is disposed at an inward inclination from its rear to its outer end, a laterally directed stretch I33 inclining downwardly from its inner to its outer end, a short vertical stretch I31, a horizontally disposed stretch I38, a vertically disposed stretch I39 and an inwardly extending forwardly inclined forward end stretch I49. The forward end of stretch I35 merges into the upper end of stretch I 35. The lower end of the latter merges into the forward end of stretch I 3?. The rear end of stretch I31 merges into the inner end of stretch I38. The outer end of stretch I33 merges into the rear end of stretch I39. The forward end of stretch I39 merges into the rear end of stretch I it. The stretches I31, I39 are disposed parallel to the lengthwise median of section I28. The stretch I38 is disposed at right angles to stretches I31, I 39 and at right angles to the longitudinal median of section I28. stretches I36, I31, I38. The stretch I39 is of greater length than stretch I38. The stretch I49 is of greater length than the other stretches, with the exception of stretch I35. The stretch I36 is of materially less length than one of the other stretches. The stretch I 48 at its forward end merges into the inner end of the wall of the combined. air intake and fluid outlet MI. The stretches I35, I36 and I99 are disposed in angular relation with respect to the other stretches and in angular relation with respect to the'longitudi nal median of section I28.

The inner side wall of said grooves I3I, I32 is formed intermediate its ends with an opening I42 which communicates with the recess I 43. The opening I 42 has a forward wall I44 and a rear wall I45. The walls I94, I45 are horizontally disposed. The opening I45 forms the said inner side wall into an inner and an outer section. The inner section consists of a stretch I46 opposing and disposed at the same inclination as the stretch I35. The stretch I46 at its forward end merges into the outer end of the wall I 45. The outer section of the inner side walls consists of a rear stretch I III opposing a portion of, disposed at the same inclination as the stretch I35 and terminating at its rear end into the outer end of the Wall I94, a horizontally disposed stretch I48, a rearwardly downwardly inclined stretch I49, a vertical stretch I50, a horizontal stretch I5I, a vertical stretch I52, and an inwardly extending forwardly inclined stretch I53. The forward end of stretch I 4'! merges into the inner end of stretch I 19. The outer end of stretch I48 merges into the upper end of stretch I99. The lower end of stretch I 49 merges into the upper end of stretch I59. merges into the inner end of stretch I5! The outer end of stretchgISI merges into the lower end of stretch I52. The upper end of stretch I 52 merges, into the rear end of stretch I53. The latter opposes stretch I99. The stretch I52 opposes stretch I39. The stretches I49 and I5I overhang stretches I39, I35. The stretch I59 ,opposes stretch MI; The stretch I98 aligns with the inner end wall I53 of the passage. The wall I54 connects the rear end of the stretches I35, I 66 together.

The lower end of stretch I59 The stretch Hi9 overhangs the The stretches I45, I41, I99 and I53,are

longitudinal median of section I28. The stretch I52 is disposed parallel to and the stretches I48, I5I, as well as the wall I54, are disposed at right angles to the longitudinal median of section I28. The inner grooves I33, I34 of section I28 are of the same form and arrangement as that of the grooves H9, I20 of section 99.

With reference to the form illustrated by Fig. ure 9, the grooves I00, IUI of one section thereof are adapted to register the grooves I00, I05 of the other section thereof to provide oppositely disposed tortuousindependenttubularpassages functioning in the same manner as the passages 12, 14. The grooves H9, I20 of the sections of the form shown in Figure 9, are adapted to register to form inner tortuous independent tubular passages functioning in the same manner as the passages 82, 83. With reference to Figure 10, the grooves I29, I39 of the sections thereof are adapted to register to form a pair of independent tortuous tubular passages functioning in the same manner as the passages 72, I4. Further with ref erence to Figure 10, the grooves I33, I3'3 of the sections thereof are adapted to register to form independent tortuous tubular passages functioning in the same manner as the passages 82, 83.

If the bottle is tilted with respect to the horizontal to the right, the passage I2 constitutes a fluid discharge passage and the passage 16 pro-- vides a combined fluid discharge and air intake passage. If the attachment is tilted with respect to the horizontal to the left, then the passage 14 forms a fluid discharge passage and the passage 12 provides a combined fluid discharge and air intake passage.

The parts of the attachment are so arranged to provide for discharge of the contents of the bottle after the attachment is disposed at an angle with respect to the horizontal and as the attachment, when extending downwardly, is moved towards the vertical, the flow decreases and completely stops when the attachment assumes an inverted vertical position. It is thought that the preventing of discharge from the bottle, when the attachment is in an inverted position and vertically disposed, is due to an air-trap effect within the attachment. The tubular passages are of like form, oppositely disposed, of tortuous type having offset closed branches and so formed as to prevent the passage of a wire or other implement to hold valve I8 off of its seat tosurreptitiously refill the bottle.

The attachment is for employment in connection with any form of container having a neck or an annular extended intake or filling member. The term container is also meant to imply a bottle or a jug. The term neck is also meant to imply an annular extended intake or filling member.
