Abstract
One of the two confined volumes, for example the "supplying" one (2), is provided with a tubular perforating element (3) confined within a space closed by a diaphragm or perforable wall (503); the second confined volume (1) also has a perforable diaphragm (301); the surfaces of the two diaphragms (503, 301) directed towards the external environment are permanently bonded together after which the perforator (3) is manipulated from the outside so as to perforate the two diaphragms, placing in communication, via the tubular duct of the perforator, the confined environment of the supplying volume with that of the second volume.
Claims21
A device for transferring products between confined volumes, the device comprising:
- a first pierceable thermal plastic diaphragm on each of the confined volumes and enclosing a section of each of the confined volumes, said thermal plastic diaphragms being adhesivable to each other when heated;
- a piercing means enclosed in a first of the confined volumes, for piercing joined thermal plastic diaphragms to form an opening between the confined volumes whereby products can be transferred between the confined volumes and bonding means for bonding said thermal plastic diaphragms, said bonding means heating said thermal plastic diaphragms, and bringing said thermal plastic diaphragms together for joining said bonding means surrounding said thermal plastic diaphragms and comprising an annular heating element.
A device for transferring products between confined volumes, the device comprising:
- means defining a first confined volume including a first volume pierceable plastic diaphragm enclosing a section of the first confined volume;
- means defining a second confined volume including a second volume pierceable plastic diaphragm enclosing a section of the second confined volume;
- a first additional pierceable plastic diaphragm and a second additional diaphragm cooperating with means to define a third confined volume, said first volume plastic diaphragm, said second volume plastic diaphragm and said first and second additional plastic diaphragm being adhesivable to each other when heated wherein said first additional pierceable plastic diaphragm is adhered to said first volume pierceable plastic diaphragm and said second additional pierceable plastic diaphragm is adhered to said second volume pierceable plastic diaphragm to connect said means defining a first confined volume and said means defining a second confined volume;
- piercing means enclosed in said third confined volume, said piercing means including two opposite piercing tips for piercing said first volume pierceable plastic volume, said first additional pierceable plastic diaphragm, said second additional pierceable plastic diaphragm and said second volume pierceable plastic diaphragm when said means defining a first confined volume and said means defining a second confined volume are connected.
A device for transferring products between confined volumes, the device comprising:
- means defining a first confined volume including a first volume pierceable plastic diaphragm enclosing a section of the first confined volume;
- means defining a second confined volume including a second volume pierceable plastic diaphragm enclosing a section of the second confined volume;
- an additional pierceable plastic diaphragm connected to said first volume plastic diaphragm to define a third confined volume, said second volume plastic diaphragm and said additional plastic diaphragm being adhesivable to each other when heated wherein said additional pierceable plastic diaphragm is adhered to said second volume pierceable plastic diaphragm to connect said means defining a first confined volume and said means defining a second confined volume;
- piercing means enclosed in said third confined volume, said piercing means including two opposite piercing tips for piercing said first volume pierceable plastic volume, said additional pierceable plastic diaphragm and said second volume pierceable plastic diaphragm, adhered to said additional diaphragm.
