Dans le cas d'une utilisation conforme, une ou plusieurs boîtes (2) peuvent être associées au compartiment (3) hygiénique, de manière que ce dernier puisse être déplacé dans l'installation (1) en même temps que la ou les boîtes (2). L'installation (1) comporte un dispositif de pliage (7). Le dispositif de pliage (7) comprend en outre un support de couvercle (71) et des rouleaux de pliage (72), un tube de remplissage (73) servant au remplissage de la boîte (2) pouvant traverser, ou en particulier traversant, le support de couvercle (71). Dans le compartiment (3) hygiénique est disposée une plate-forme (31) sur laquelle une boîte (2) peut être placée, cette plate-forme (31) pouvant être soulevée avec la boîte (2) en direction de l'ouverture d'entrée (30) pour le produit de remplissage lors d'une utilisation conforme, et le compartiment (3) hygiénique pouvant être fermé avec une structure enveloppante (32) disposée autour de la plate-forme (31) et une plaque de tête (33). La structure enveloppante (32) peut être soulevée jusqu'à la plaque de tête (33) en direction de l'ouverture d'entrée (30) pour fermer le compartiment (3) hygiénique, ou bien cette structure enveloppante (32) est fixée à la plaque de tête (33) de sorte que la plate-forme (31) puisse être soulevée dans la structure enveloppante (32).
