Embodiment Construction

[0061] In the following, longitudinal, vertical and transverse directions are taken with reference to the coordinate system (L, V, T) shown in the drawings without limitation.

[0062] Typically, the longitudinal direction and the transverse direction, which together define a horizontal plane, are fixedly determined relative to the container.

[0063] Without limitation, the terms "upstream" and "downstream" are used with reference to the direction of movement of containers conveyed by a conveyor system from upstream to downstream along a given route.

[0064] Also without limitation, the expressions "upper" and "lower" or "higher" and "lower" are used with reference to vertical directions. The expressions "inner" or "outer" and "inner" or "outer" are used in particular with respect to a container, the inner volume being defined by a container wall, the container body being provided with a neck and closed by a bottom, so that the container walls define the inside and the outsi...

Abstract

The invention further proposes a sterilization device (100) for sterilizing, by irradiation, at least one container (10) made of thermoplastic material of the type having a main axis (O) and comprising a body (12) provided with a neck (14) and closed by a base (16), said device (100) comprising at least one emitter (120) provided with a head (125) which, having a main axis (A), is intended to emit a beam (F) of electrons for irradiating said at least one container (10) from the outside, characterized in that said at least one emitter (120) is configured to be able to tilt the head (125) at an inclination angle (alpha) which, included between the main axis (A) of the emitter and the axis (O) of the container, is determined as a function of the height (h) of the container in order to optimize the dose of irradiation received by said container (10).

Description

technical field [0001] The invention relates to a radiation sterilization method and radiation sterilization device for a thermoplastic material container. [0002] In particular, the invention relates to a radiation sterilization device for radiation sterilization of at least one container made of thermoplastic material with a main axis, the container having a body provided with a neck and closed by a bottom , the device has at least one emitter provided with a head having a main axis for emitting an electron beam to irradiate the at least one container from the outside. In other words, the head is an integral part of the emitter which defines the frontal section of the emitted electron beam, the main axis of the emitter being the largest dimension of the frontal section of the electron beam. [0003] The invention also relates to a method of radiation sterilization for the radiation sterilization of a flow of containers made of thermoplastic material with a main axis by mea...
