'Integral with the bottom section 15 oathe base p0rtion,.there isprovided aicylindrical portion @lfhaving an outer' diameter-lessthan the' inner diameter of thezcupshaped .ibase and extended `upwardly fromfthe bottom sectionrs15 and :.throughzzthe open fend.' of: thezbase portioniorlanyudesired distance :The inner-'faces org/the baseportions 15, k17l and f18 4are straight rand. form with the 'cyli-ridiielportion 21, an'xannular' we1l'f22 in the baseportion. The bore of the tubular portion 21 is extended through the bottom section 15 to form a discharge passage 23 for the contents of the container 10. The outer or upper end of the cylindrical portion 21 is provided with an annular inturned lip 24 to constrict the outer or upper end of the passage 23. An intermediate portion of the discharge passage 23 is provided with a valve seat integralwith the cylindrical portion 21. In Figures 1, 2 and 3, they valve seat is formed by a wall 25 extending transversely of the discharge passage and having an axial opening 26 therethrough.

The mounting member is permanently secured in the container neck by engaging the bottom section 15 in the constricted throat portion 12 with the bulbous section 17 abutting said throat portion. Then a downward pressure is applied simultaneously to the upper end of the spout shoulder section wall 18 and to the upper end of the bottom section 15, which is the bottom wall of the well 22, whereby the bulbous section 17 is flexed around the constricted throat portion 12 of the container neck. The well 22 will permit the exing of the bulbous section 17 around the constricted throat portion 12. Due to the inherent characteristic of the material of the mounting member, such as polyethylene, to assume its original condition, the bulbous section 17 will tightly engage around the constricted throat portion 12 and wedge the mounting member in the container neck to form a -liquid-tight and tamper-proof seal. The downward pressure applied tothe bottom section 15 and to the top section 18 will also cornpress the

shoulder section

18, 19 into the shoulder portion 13, 14 to form a second liquid-tight seal between the container neck and the mounting member. Flexing of the cylindrical portion 21 in a lateral direction will not loosen the mounting member in the container neck, but will have a tendency to place a tension on the lower part of the bulbous section 17 against the lower part of the constricted throat portion 12. Downward pressure on the cylindrical portion 21 will not loosen the mounting member in the container neck, but will have a tendency to tighten the engagement between the walls 13 and 19 and urge the bulbous section 17 against the constricted throat portion 12. An upward pull on the cylindrical portion 21 will not remove the mounting member from the container neck as said pull liexes the bottom-section 15 outwardly against the tapering base portion 11 of the container neck. The top section wall 18 is of greater length than the neck wall 14 and during the compression of the

top section

18, 19 into the shoulder portion 13. 14, the upper part of the top section wall 18 will expand laterally over the top edge of the shoulder portion wall 14 whereby it is not possible to insert an instrument between the top section wall 18 and the shoulder portion wall 14 to pry the mounting member loose from the container neck. Due to the resiliency of the mounting member, the downward pressure applied thereto in securing the mounting member in the container neck will not collapse the container top wall.

It is to be understood thatthe mounting member is adapted to be secured in or attached to other types of containers than that disclosed in the drawing.

The other member of the embodiment of the invention, as shown in Figures 1 to 5, inclusive, is a valve-spout member of resilient material, such as polyethylene, and comprising a tubular portion 27 having a liquid-tight sliding tit with the constricted end 24 of the discharge passage 23 and an enlarged portion 28 at the inner end of the tubular portion 27 and having a straight side wall sliding in the discharge passage 23 above the

valve seat

25, 26. The tubular portion 27 is provided with an axial bore 29 extended partially into the enlarged portion 28, as shown in Figures l, 2 and 3, and communicating with a port 30 extending laterally through the lower section of theienlarged portion 28 on one side of .the longitudinal axis of the valve-spout member, wherebyv the bore 29 communi- .cares with the discharge passage 23. The communication of the bore 29 with the lower portion of the discharge l 28 is adjacent to or abuts the inturned lip 24, the pin 31 is fully disengaged from the opening 26, as shown in Figure 1, and when the lower end or the bottom of the enlarged portion is adjacent to or a'buts the wall 25, the pin 31 is fully engaged in the opening 26 with the conical end 32 extending below the wall 25, as shown in Figure 2. The port 30 extends radially of the pin 31, as shown in Figure 4.

To discharge the contents of the container, the valvespout member is pulled upwardly to disengage the pin 31 i from the opening 26 and the container 10 is inverted to cause the flow of the contents from the container into the lower portion of the discharge passage 23 and through the opening 26 into the upper portion of the discharge passage 23 and thence to the bore 29 through the port 30.

The rate of tiow of the contents of the container through vthe bore 29 can be controlled by the extent the valve-spout member is pulled upwardly in the mounting member, as shown in Figure 3, wherein the conical end 32 is partially positioned in the opening 26.

To discontinue the discharge of the contents from the container, the valve-spout member is pushed into the mounting member to fully engage the pin 31 in the opening 26, as shown in Figure 2.

To facilitate the breaking of the liquid-tight engagement between the pin 31 and the opening 26 when it is desired to discharge the contents from the container, the section of the tubular portion 27 extending above the mounting member cylindrical portion 21 is provided with longitudinal knurls or tintes 33 so that the valve-spout member can be simultaneously rotated and pulled in an upward direction.

Figures 6 to 9, inclusive, show modified forms of the valve seat in the mounting member and the enlarged portion of the valve-spout member. The modified form of valve seat comprises a wall 34 integral with the cylindrical portion 21 and extending transversely of the discharge passage 23. Said wall 34 is arranged with openings 35 in diametrically opposite portions of the wall 34 and a pin Aor projection 36 integral with said wall and extending upwardly therefrom. The modified form of enlarged portion of the valve-spout member comprises a spherical portion 37 at the lower end of the tubular portion 27 of a diameter to form a liquid-tight sliding fit with the inner wall of the cylindrical portion 21 above the valve seat wall 34. The spherical portion 37 is provided with an axial opening 38 corresponding to the size and shape of the valve seat pin 36 to form a liquid-tight sliding tit with said pin when the valve-spout member is moved into the mounting member. The opening 38 is in axial alignment with the bore 29 of the tubular portion 27 and the upper end of the opening 38 communicates with the lower end of the bore 29. The diameters of the valve seat pin 36 and the opening 38 are greater than the diameter of the bore 29. tion 27 in the modified form of the enlarged portion 37 shown in Figures 6, 7 and 9 is smaller than the diameter of the bore 29 of the tubular member 27 shown in Figures l, 2 and 3. The advantage of the modified forms shown in Figures 6 to 9, inclusive, is that the valve-spout mem- 'ber can be accidentally tilted or tipped in the mounting member without breaking the liquid-tight seal between the spherical portion 37 and the inner wall of the cylindrical portion 21.

The operation ofthe modified forms shown in Figures 6 to 9, inclusive, is the same as the structure shown in Figures 1 to 5, inclusive, whereby in the lowermost posi- The diameter of the bore 29 of the tubular por-' tion of the valve-spout member in the mounting member, the opening 3S engages the pin 36 and closes the communication between the discharge passage 23 and the bore 29, and the container is sealed. In the uppermost position of the valve-spout member in the mounting member, the communication between the discharge passage 23 and the bore 29 is open and the contents of the container is discharged upon tilting or inverting the container.

Due to the resiliency of the material of the mounting member and of the valve-spout member, the valve-spout member is readily assembled in the mounting member by forcing the

enlarged portion

28 or 37 past the inturned lips 24.

Having thus described my invention, I claim:
