Abstract

A dosing bottle made in one piece from plastic using a blow molding or an injection molding method. With at least one mash seam or a constriction in the bottle walls, a separate dosing chamber with an opening passing through to an inside of the bottle is formed at a bottom of the bottle. The dosing chamber communicates with an outlet tube which runs through the inside of the bottle to an opening in such a manner that whenever the bottle is tipped forwards by 90° to 180° from its upright position into a pouring position, only the liquid in dosing chamber can be poured out of the bottle.

Claims

1. A dosing bottle for dispensing fixed doses, comprising:

a bottle (1) made in one piece from plastic using one of a blow molding and an injection molding method, one of at least one mash seam (6) and a constriction in bottle walls forming at a bottom of the bottle (1) a separate dosing chamber (3) with a first opening (4) passing through to an inside of the bottle (1), the dosing chamber (3) communicating with an outlet tube (5) running through an inside of the bottle (1) to a second opening (7) such that whenever the bottle (1) is tipped forwards by 90°

to 180°

from an upright position into a pouring position only an amount of liquid in the dosing chamber (3) can be poured out of the bottle (1) and wherein the second opening is the sole liquid fill and dispensing opening for the bottle.

2. The dosing bottle of claim 1, the at least one mash seam (6) separates dosing chamber (3) and extends along the bottom of the bottle (1), the dosing chamber (3) runs into a vertical outlet tube (5) which communicates with the second opening (7) on one side and at a top on an other side has the first opening (4) by which the dosing chamber (3) can be refilled when the bottle (1) is in the upright position.

3. The dosing bottle of claim 2, further comprising a sealable air bleed vent (14) on a top side of bottle (1) next to the second opening (7).

4. The dosing bottle of claim 2, wherein the bottle (1) has a third opening (9) forming a handle (21) with which the bottle (1) can be tipped forward with one user hand.

5. The dosing bottle of claim 1, wherein one of the mash seams (6) on an inside of the dosing chamber (3) extends along the bottom of the bottle (1) and separates the outlet tube (5) that runs vertically along one side of the bottle (1) and communicates with the dosing chamber (3), the outlet tube (5) communicates with the second opening (7), the dosing chamber (3) has the dosing chamber opening (4) at a top of an other side, by which the dosing chamber (3) can be refilled when the bottle (1) is in the upright position.

6. The dosing bottle of claim 5, further comprising a sealable air bleed vent (14) on a top side of bottle (1) next to the second opening (7).

7. The dosing bottle of claim 5, wherein the bottle (1) has a third opening (9) forming a handle (21) with which the bottle (1) can be tipped forward with one user hand.

8. The dosing bottle of claim 1, wherein with a constriction in the bottle walls the bottom of the bottle (1) is molded into two feet (2, 19), one foot (2) of the feet (2, 19) forms the dosing chamber (3) with the outlet tube (5) running at an angle through an inside of the bottle from the opening (7) to end below a top edge (22) of the dosing chamber (3), wherein a space between a bottom tube opening (23) and an inside wall of the bottle (1) forms the opening (4) through to the dosing chamber (3) so that whenever the bottle (1) is tipped forwards by 90°

to 180 °

from the upright position into the pouring position only the amount of the liquid in the dosing chamber (3) can be poured out of the bottle (1).

9. The dosing bottle of claim 8, further comprising a sealable air bleed vent (14) on a top side of the bottle (1) next to the opening (7).

10. The dosing bottle of claim 9, wherein the bottle (1) has a third opening (9) forming a handle (21) with which the bottle (1) can be tipped forward with one user hand.

11. The dosing bottle of claim 8, wherein the bottle (1) has a third opening (9) forming a handle (21) with which the bottle (1) can be tipped forward with one user hand.

12. The dosing bottle of claim 1, further comprising a sealable air bleed vent (14) on a top side of bottle (1) next to the second opening (7).

13. The dosing bottle of claim 1, wherein the bottle (1) has a third opening (9) forming a handle (21) with which the bottle (1) can be tipped forward with one user hand.
