Abstract: Process for soldering the lower corners of a bag. Liquid is forced by the gradual moving together of two concave flasks (105, 106), of which the point of contact rises gradually towards the top with the relative moving together of the jaws (100, 101). Application to the conditioning of liquids.

Abstract: Device for manufacturing a sachet of flexible synthetic material intended for packaging liquids, the sachet initially being in the form of a cushion-like bag already full of liquid, this device enabling a means for gripping, stiffening and mounting information to be attached to the said cushion-like bag and enabling the sachet to be given its final shape for marketing and use.The device includes means for enclosing the cushion-like bag in a sleeve of synthetic material which can be stretched and is cold-worked around clamping jaws (19,20) which are capable of a translation motion and a motion away from one another, between which the cushion-like bag is located.

Abstract: A device for perforating a pack made of flexible synthetic material and having a closing-off and pouring assembly including a cylindrical shank and a plug for interacting with the shank and for cutting and perforating the pack in order to access a liquid contained in the pack, is improved by providing the shank with a reinforcement attached to and extending from the base of the shank, partially inwardly toward the center of the shank. Also the method of manufacturing the device.

Abstract: The front face of a bag, made of flexible material obtained from a strip of synthetic film shaped to define a bottom and a pair of side walls connected by a stiffening and gripping zone to the front face, from which contents of the bag are poured, is provided with structure for stiffening and stabilizing said bag.

Abstract: Welding and cutting process in which the bag is disposed in a holding unit (107) supporting and positioning it, and is composed of a side plate (108), a stop plate (109), and a closing angle member.

Abstract: A method for positioning handles on a sachet-type container made from a flexible synthetic material comprises attaching handles to a sleeve of synthetic material while the sleeve is on the mandrel. The sleeves are cut and flap-like corner portions are folded over onto the handles. The handles may be fed from a magazine.

Abstract: A bag made of flexible synthetic material is provided with a removable stiffening element that can serve as both a handle and a stopper element after the bag has been opened.
