Claim 3

said upper chamber is developed as a flood chamber and said pouring chamber further has an overflow opening, and a beaker extends below the upper chamber, said pouring chamber extends from said delivery tube and is arranged with flow clearance within said beaker, said beaker is formed with another hole at approximately the height of the transverse wall, said another hole is in communication with said overflow opening.

Claim 4

said upper chamber is developed as a flood chamber and said pouring chamber further has an overflow opening, and a beaker extends below the upper chamber, said pouring chamber extends from said delivery tube and is arranged with flow clearance within said beaker, said beaker is formed with another hole at approximately the height of the transverse wall, said another hole is in communication with said overflow opening.

Claim 5

The device according to claim 1, wherein said beaker is formed with a plurality of channels which are spaced angularly from each other and which define said flow clearance between said pouring chamber and said beaker.

Claim 6

The device according to claim 2, wherein said beaker further comprises wall sections between said channels, said wall sections rest against the outer surface of said pouring chamber.

Claim 7

The device according to claim 1, wherein said beaker is formed with a plurality of channels which are spaced angularly from each other, respective ones of said channels and said air passage openings are arranged along a same respective radius.

Claim 8

The device according to claim 1, wherein a region of the mouth of the delivery tube forms an outwardly-directed collar forming a funnel, and a bottom part of said collar is in non-rotatable engagement with ends of said feed tubes.

Claim 9

In a device adapted for the dosed dispensing of liquid from a storage container through a delivery tube which comes out of a lower pouring chamber upon a second upside down turning, a housing shaped as a cup having a transverse wall at a bottom of the cup and defining an upper chamber, the pouring chamber and the upper chamber communicating with each other through a flow hole, the transverse wall being traversed by a feed tube opening thereabove, said delivery tube projecting above the feed tube and an air passage extends through the transverse wall, the improvement comprising at least three of said feed tubes arranged in symmetrical angular distribution with a respective said air passage opening arranged between them, said cup-shaped housing comprises a cup-forming annular wall of a first part of the housing, said housing being formed as an insert, a rim edge of the cup being bent over to form an insertion groove and disposed for sealing over a stepped-down end region of a neck of the container, and wherein said feed tubes extend from said transverse wall and are directed upward in the direction of dispensing and are formed in said cup-forming annular wall, and said feed tubes extend above said rim edge by an amount substantially equal to the depth of said cup.

Claim 10

In a device adapted for the dosed dispensing of liquid from a storage container through a delivery tube which comes out of a lower pouring chamber upon a second upside down turning, a housing shaped as a cup having a transverse wall at a bottom of the cup and defining an upper chamber, the pouring chamber and the upper chamber communicating with each other through a flow hole, the transverse wall being traversed by a feed tube opening thereabove, said delivery tube projecting above the feed tube and an air passage extends through the transverse wall, the improvement comprising at least three of said feed tubes arranged in symmetrical angular distribution with a respective said air passage opening arranged between them, said cup-shaped housing comprises a cup-forming annular wall of a first part of the housing, said housing being formed as an insert, a rim edge of the cup being bent over to form an insertion groove and disposed for sealing over a stepped-down end region of a neck of the container, and wherein said feed tubes extend from said transverse wall and are directed upward in the direction of dispensing and are formed in said cup-forming annular wall, and said feed tubes extend above said rim edge by an amount substantially equal to the depth of said cup.

Claim 11

The device according to claim 6, wherein said transverse wall forms a bottom of said cup and extends into a substantially cylindrical beaker of reduced cross section relative to said cup, the height of said beaker corresponding approximately to 21/2 times the depth of said cup.

Claim 12

The device according to claim 7, wherein said beaker is formed in one-piece with said first part of said housing and surrounds said pouring chamber defining a clearance enabling passage of the liquid between an outer wall of said pouring chamber and an inner wall of said beaker.

Claim 13

The device according to claim 8, wherein said beaker comprises three angularly spaced channels which extend in a longitudinal direction of the beaker and come together in the region of the bottom of the beaker, said channels are formed by a circumferential meander-like bending of the beaker wall, said beaker wall further comprises wall sections between said channels, said wall sections rest against the outer surface of said pouring chamber, said clearance being defined by said channels.

Claim 14

The device according to claim 7, wherein said beaker is slightly conical.
