The container body is connected to a head or top. A part of the head can be detached for opening of the container. A segment of an extruded tube is mounted in a blow mold having an axially movable mold base. The diameter of the extruded tube is slightly greater than the diameter of the head or top. Following the closing of the tube end forming the bottom of the container, air is blown into the tube and simultaneously the mold base is moved toward the top jaws of the blow mold forming the head. After filling of the container and possibly mounting of an insert body into the top segment of the tube forming the container head or top, the mold base is moved still further in the direction of the top jaws, until the container is free of air. Then, the head is formed and is sealed securely with the outer surface of the insert body.
What is claimed is: 1. A method for manufacturing a sealed container filled with a liquid substance, comprising the steps of:positioning a portion of an extruded tube in a blow mold to form a container having a body with a body diameter, a detachably mounted head to facilitate opening the container with a head diameter considerably smaller than the body diameter and a transition part between the body and the head substantially extending in a radial plane, the tube having a diameter slightly greater than the head diameter, the blow mold including main laws between top jaws and a mold base; closing a bottom end of the tube forming a bottom of the container; blowing air into the tube, after the tube bottom end is closed, and simultaneously moving the mold base in a first movement toward the top jaws of the blow mold to decrease a space inside the main jaws; filling the container in the blow mold with the liquid substance; moving the mold base further toward the mold top jaws until the container is free of air; and forming a top segment of the tube with the top jaws into the container head and sealing the formed container. 2. A method according to claim 1 whereinthe mold base first moves toward the mold top jaws to a first position corresponding to the size of the sealed container when air is blown into the tube; and the mold base moves slightly away from the mold top jaws during the filling of the container with the substance. 3. A method according to claim 2 whereinthe mold base, after completion of the filling of the container with the substance, moves towards the mold top jaws back to the first position. 4. A method according to claim 1 whereinduring the first movement of the mold base, air is first blown into the tube at a relatively low pressure; and shortly before the mold base reaches a first position corresponding to the size of the sealed container, the air pressure of the blown air is increased to a set value. 5. A method according to claim 3 whereinsubsequent to filling the container with the substance, during movement of the mold base toward the mold top jaws and during the forming of the tube top segment to seal the container, air and any excess substance are removed from the container by suctioning. 6. A method according to claim 5 whereinan insert body is placed in the tube top segment before forming the container head, the tube top segment being formed to engage and seal peripheral surfaces of the insert body. 7. A method according to claim 6 whereinthe suctioning of the air and the excess substance in the container occurs through the insert body. 8. A method according to claim 6 whereinthe container head is welded about a periphery of the insert body. Description
Top 3 is provided with such a break point, which in this case is approximately at the level of the dividing plane between first part 8 and second part 9 in the form of a circumscribing groove 10. Groove 10 penetrates radially from the outside and reduces the otherwise relatively considerable wall thickness of top 3 to a minimum. Circumscribing groove 10 has a triangular cross- sectional profile, to permit tilting of the part of top 3 to be broken off for the purpose of separating the parts.
Before opening the container, the needle extends into a central passage channel 16 in second part 9 of the insert body. Adjacent first part 8, central passage channel passage 16 has a considerably greater diameter than the diameter of hollow needle 14. The remainder of the central passage through second part 9 is of dimensions adapted to or substantially equal to the diameter of hollow needle 14. The end of central passage channel 16 remote from first part 8 is closed and sealed off by the material of top 3 which also forms a sheathing for the insert body.
