摘要:
A manufacturing process for flexible tube skirts including the steps of providing a multi-layer plastic film, cutting out a strip from the multi-layer plastic film, producing a cylindrical sleeve by rolling-welding the strip, and cutting out the sleeve to the desired length to obtain the tube skirts. The strip is cut out from a multi-layer plastic film which has a symmetrical structure in relation to its median plane, with symmetrical layers having the same thickness and made of the same plastic, having the same chemical composition and the same molar mass.

The present invention relates to a drug delivery device defining a reservoir for containing a product, having a distal end comprising an end-piece defining a channel for the transfer of the product from the reservoir, said drug delivery device comprising means for coupling said end-piece with a connector, said coupling means comprising a collar defined around a portion of the end-piece and extending from the distal end, said coupling means comprising connection means connectable to said collar, said connection means comprising a tubular wall portion having an interface defined thereon for engagement with an internal face of said collar, and a retaining hook having engagement means engageable with at least part of an external face of said collar when said connection means is connected to said collar.
摘要:
A method for decorating the cylindrical walls of receptacles, comprising the following steps: a) moveable mandrels are arranged in a loop and are displaced, keeping their axes parallel to a direction D; b) each receptacle is engaged by the cylindrical wall thereof on the mandrel; c) the mandrel is brought into the vicinity of a marking cylinder which turns about a fixed axis parallel to direction D; d) the mandrel is rotated at a speed which is correlated with that of the marking cylinder; e) a transfer film support strip is displaced between the marking cylinder and the mandrel; f) the marking cylinder and mandrel are placed in contact with each other such that the marked area of the transfer film adheres to the cylindrical wall; g) the support strip is removed from the cylindrical wall of the receptacle. The inventive method is adapted to the manufacture of flexible tubes and can be easily implemented on existing devices such as capping machines.

Apparatus for manufacturing flexible tubes comprising a skirt and a head provided with a neck and a shoulder linking the neck to the skirt, the apparatus having a first zone devoted to manufacturing the skirts, a second zone devoted to manufacturing the flexible tubes, a third zone devoted to finishing the flexible tubes thus produced, a first transfer device transferring the skirts in continuous motion from the first zone to the second zone, and a second transfer device transferring, in continuous motion synchronized with the former, the tubes from the second zone to the third zone. The second zone has a third transfer device for transferring the punches in continuous motion synchronized with that of the first transfer device and with that of the second transfer device, loading device for loading the skirts on the punches associated with the synchronized movement of said first and third transfer devices, and unloading devices for freeing the punches from the tubes covering them for associated with the synchronized movement of the second and third transfer devices.

An adapter for use with a drug delivery device having a reservoir for containing a product, the reservoir having a distally projecting end-piece defining a passageway for the transfer of the product from the reservoir, includes a collar engageable with the end-piece, an adaptor securing member limiting translational movement of the collar with respect to the end-piece once the collar is engaged with the end-piece, at least one adaptor anti-rotation member limiting the rotation of the collar with respect to the end-piece once the collar is engaged with the end-piece, at least one deactivating member neutralizing the adaptor anti-rotation member in response to a turning torque equal or greater than a predetermined value applied to the collar when the collar is engaged with the end-piece, thereby allowing the rotation of the collar with respect to the end-piece.
摘要:
A hinged-lid closure equipped with a lid and a base including a plate, an attachment skirt and an external lateral skirt, where the attachment skirt is thicker than the plate and the external lateral skirt. The base is equipped with a radial longitudinal rib attached to an internal surface of the external lateral skirt and located in a plane mid-perpendicular to the hinge.

摘要:
The present invention relates to a drug delivery device comprising, a reservoir for containing a product, said reservoir having a distally projecting end-piece having a longitudinal axis A and defining a channel providing a passageway for the transfer of the product from the reservoir, an adaptor having a collar engageable with said end-piece, securing means for blocking said collar in the distal direction with respect to said end-piece once said collar is engaged around said end-piece, anti-rotation means for preventing the rotation of said collar with respect to said end-piece around said longitudinal axis A under the effect of a turning torque applied to said collar once said collar is engaged around said end-piece, deactivating means for neutralizing said anti-rotation means once said turning torque has reached a predetermined value, thereby allowing the rotation of said collar with respect to said end. The invention also relates to such an adaptor.
