## Abstract

The invention concerns a method of manufacturing a container in a blowing mould, the blown container having a neck and a bottom aligned along a longitudinal axis and being enclosed within a blowing mould, the blowing mould comprising two side halves which are in contact with each other along a joint plane when the blowing mould is in a closed position, the blown container having at least one transverse dimension in a longitudinal cross-section including the longitudinal axis, characterized in that the method comprises a step of moving apart the two side halves of the blowing mould along a substantially transverse direction, the two side halves being moved apart from the joint plane over an overall distance that is less than the greatest transverse dimension of the blown container and that enables extraction of the blown container from the blowing mould.

## Claims

### Claim 1

An apparatus for manufacturing a container in a blowing mold, the apparatus comprising a blowing mold including a first side half and a second side half, the first side half comprises a first side half mold face, and the second side half comprises a second side half mold face, the first side half mold face and the second side half mold face are in contact with each other along a joint plane when the blowing mold is in a closed position, the blowing mold configured to enclose a blown container, the blown container having at least one transverse dimension in a longitudinal cross-section including a longitudinal axis and a member configured to move the first side half and the second side half apart along a transverse direction to separate the first side half mold face from the second side half mold face, the first side half and the second side half configured to be moved completely apart from the joint plane over an overall distance that is less than the greatest transverse dimension of the blown container and that enables extraction of the blown container from the blowing mold.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the apparatus comprises an extractor configured to extract the blown container from underneath the blowing mold.

### Claim 3 (depends on 1)

The apparatus according to claim 1, wherein the blowing mold comprises a bottom part, and the apparatus comprises a member configured to move the bottom part of the blowing mold on which rests the blown container away from the first side half and the second side half.

### Claim 4 (depends on 1)

The apparatus according to claim 1, wherein the member configured to move the first side half and the second side half is selected from the group consisting of a hydraulic piston device, a pneumatic piston device, and a cam.
