摘要:
The invention relates to an apparatus in a tube filling and sealing machine for heating a portion of the interior surface (2) of a plastics packaging tube (1) which is open at one end. Means are provided for directing a spot type light from at least one light source (S1, S3) to a predetermined level on the interior surface (2) around the internal perimeter of the tube while the tube is rotated, so as to generate heat build-up at said surface in order to soften the plastics material to activation temperature. Said at least one light source will typically be a laser source. A heat sink means (20) is arranged in a position for circumferentially enclosing the tube end at level where said spot type light is swept, said heat sink means being in rotational sliding contact with the tube for improving the transfer of any excess of heat energy.

The invention relates to a method for filling a tube (3) with a paste, ointment, gel or cream (4). Said tube (3) consists of a tubular or conical casing produced from a flexible material. At its one end the tube has a closable filling opening (9) and at the end opposite said filling opening (9) the tube is closed. Once the paste, ointment, cream (4) or the gel have been filled into the tube, the filling opening (9) is flattened at least in its marginal zone, the inner volume of the tube is reduced by means of a die (11) that deforms the casing and the filling opening (9) is closed. During the steps of flattening and closing the filling opening (9) the inner volume of the tube (3) is simultaneously reduced. The inventive method provides an inexpensive, simple and unproblematic means for reducing the volume of the remaining gas-filled space in the closed tube that requires only slight modifications to the filling installation and no modifications at all to the filling process or to the tube as such.

A machine (M) includes an endless close-looped conveying line (1): in a loading station (S1) the tubes (3) are fed while being kept with the open end upwards and are carried to an infeed station (SA) in which product dispensing means (5) feeds paste product to the tubes. In a following station (S2) overhanging gripper means (6) close the tubes (3), which are then downloaded from the conveying line (1) at a download station (S3) situated downstream and near to said loading station (S1). The gripper means (6) are designed in such a way that they have no mechanical means, requiring lubrication, which are situated above the tubes (3) and the product dispensing means (5) can be removed from the machine structure (100) to be cleaned and sterilised in a room away from the machine (M).

The invention relates to a device for packaging a sterile bulk product, particularly a dermocosmetic or galenic preparation, in a container (210). Said device includes: a. a sterile chamber (101); b. a hopper (200) that is located in said sterile chamber, contains the bulk material, and includes, in an axial direction, a cylindrical tank portion (201) and a discharge portion (202) connected to the cylindrical portion (201); c. a transfer device (115) capable of transporting the container (110) under the hopper (200) with a view to filling said container in a so-called "filling" area; and d. a device (150) for blowing ultra-filtered air from the ceiling to the floor of the chamber (101), which is capable of producing a so-called "protective" air flow around the filling area; e. characterized in that the axis (205) of the dissymmetrical, tapered discharge portion (202) is offset relative to the axis (210) of the tank portion (201) such as to divert the discharge opening (206) toward the outer wall of the tank.

The invention relates to a heating device for heating the edges of the fill opening of a tube by means of heating gas. Said device comprises a heating gas nozzle which has a first nozzle section that can be inserted into the interior of the tube. The section has a first heating gas channel comprising at least one first heating gas outlet which can be arranged in the interior of the tube and the heating gas of which can be applied to the inner wall of the tube. In addition, the heating gas nozzle has a second nozzle section with a second heating gas channel comprising at least one second heating gas outlet which can be arranged on the outer face of the tube wall and by means of which heating gas can be applied to the outer wall of the tube. A flow-rate control device is arranged in the first heating gas channel and/or in the second heating gas channel.

When inspecting a sealing cap (13) of a tube (11) in a tube filling machine, the presence of the sealing cap (13) is detected. When the sealing cap (13) is present, a torque is applied thereto in the closing direction, provision being made that the torque be applied to the sealing cap (13) only after the tube (11) has been filled. The torque may be applied to the sealing cap (13) of the tube (11) in a tube closing station (S) or in a cap turning station (K) disposed downstream of the tube closing station (S).

A high-consistency liquid filling system for a soft vessel, comprising a vessel transporting means for transporting a vessel body formed of a soft membrane at at least the trunk thereof, an injection means for injecting a high-consistency liquid into the vesse body, a pressing means for pressing the trunk of the vessel body to raise the surface of the high-consistency liquid and a plugging means for setting a lid member in an opening of the vessel body. A device for filling high-consistency liquid, comprising the injection means for injecting the high-consistency liquid into the vessel body transported by the vessel transporting means, the pressing means for pressing the trunk of the vessel body to raise the surface of the high-consistency liquid and a plugging means for setting the lid member in the opening of the vessel body, whereby the lid member can be set in the opening air-tightly with the air in the vessel body almost completely exhausted so as to prevent the air from remaining in the vessel body and deterioration in quality and hardening of the high-consistency liquid otherwise be caused by remaining air.
