A bioplastic collapsible dispensing tube may include a collapsible tube having walls that include a bioplastic material; a distal end of the tube that is sealed; a proximal end of the tube, opposite the distal end, that has an opening; a nozzle on the opening; and a closure for the nozzle; wherein, when the closure is opened and the tube is collapsed, flowable material inside the tube is urged out of the nozzle; and the bioplastic material includes a bio resin selected from the group consisting of PEF, PBF, PTF, GPE, GPET, PLA, PDLA, and PLLA. A method may include forming a tube and filling the tube with flowable material from the distal end.

Verfahren zur Herstellung einer mit einem bis in den Siegelungsbereich (101) oder Teilen davon reichenden Etikett (21) versehenen Kunststoffquetschtube, bei der nach dem Befüllen über ein offenes Ende anschließend das offene Ende durch Verschweißen versiegelt wird, wobei das Etikett (21) vor dem Verschweißen nur in einem außerhalb des Siegelungsbereiches (101) liegenden Bereich mit der Tube (10) haftend verbunden ist und wobei der übrige Bereich des Etiketts (21) erst durch Wärmeeinwirkung und mittels eines Anpressdruckes beim Versiegeln an der Tube (10) haftend befestigt wird.
摘要:
In accordance with the present inventive concept, there is provided a device for sealing a flexible package (200) of collapsible type. The device comprises a first sealing unit (120) arranged to provide a first seal (302) extending transverse a filling channel of the flexible package (200) and a second sealing unit (130) arranged to provide a second seal (304) extending transverse a filling channel of the flexible package (200). The second seal (304) overlaps the first seal (302) such that a combined seal is provided comprising a top portion (312) formed solely by the first sealing unit (120), an intermediate portion (316) formed by the first (120) and the second (130) sealing unit, and a bottom portion (314) formed solely by the second sealing unit (130). Furthermore, the present inventive concept also relates to an associated method.

The invention relates to a method and a device for end closure of packaging tubes. In one embodiment, the tube which is to be sealed presents an intermediate wall having a surplus length across the tube cross section, and the intermediate wall being fixed at the filling end of the tube to the tube wall and elsewhere along two joining locations extending along the length of the tube. Between these joining locations and the fixing sites at the tube end there are material portions of the intermediate wall. A hot air nozzle with two sub-members forming a gap therebetween is inserted into the opening in the filling end, possibly with re-forming of the filling end, and parts of the intermediate wall and the inside of the tube intended for sealing are heat activated in a non-contacting manner. In another embodiment, the tube which is to be sealed presents an intermediate wall formed in one piece with the tube and joined to this along two joining locations extending along the length of the tube. A device producing a clamping action is pressed against the heat activated tube end and the intermediate wall. Said arrangement has a pair of clamping jaws arranged for translatory motion perpendicular to the tube axis and initially in a direction at an angle to a line through said joining locations.

Bei einem Befestigen eines Verschlusses (2) an einem Behälter (1) werden der Behälter (1) und der Verschluss (2) in einer Ausgangsstellung zueinander positioniert und anschließend form- und vorzugsweise auch kraftschlüssig miteinander verbunden. Der Verschluss (2) wird bei dem Positionieren mittels Klemmgriff gehalten. Der positionierte Verschluss (2) wird von einem nichtklemmenden Haltemittel (5) übernommen, und der Klemmgriff des Verschlusses (2) wird vor dem form- und vorzugsweise auch kraftschlüssigen Verbinden gelöst.
摘要:
A synthetic resin material of an end portion (5) which protrudes from a clamp jig (9) is heated and melted, and this protruding end portion is pressed and molded to a seal portion (8) inside a press molding space defining a gap into which the synthetic resin material intrudes between an aluminum foil layer (3c) and a mold surface, thereby setting the appearance of the seal portion (8) to a desired shape and completely covering the aluminum foil layer (3c). Further, the seal strength is increased by attaining a higher density by pressing.
摘要:
Eine Zange zum Zusammendrücken und Verschließen von Tubenenden hat zwei durch eine Zangenachse (3) gelenkig miteinander verbundene Hebel (1, 2), welche an den kürzeren Hebelarmen Preßbacken (7, 8) zum Zusammenpressen eines aufgewickelten Tubenendes aufweisen. An den Enden der längeren Hebelarme ist jeweils ein Andrückkörper (6, 6a) angeordnet, mit dem man die gefüllte Tube am Ende flachdrückt. Ein Wickelkörper kann in die Zange eingesetzt werden, um das flachgedrückte Tubenende aufzuwickeln.
摘要:
L'invention a pour premier objet un procédé de fermeture d'un tube souple rempli d'un produit (7) liquide, crémeux ou semi-pâteux, dans lequel on pince sa jupe (2) en-dessous de son extrémité ouverte de façon à réaliser une fermeture (10) laissant s'échapper l'air contenu dans le tube lorsque celui-ci est comprimé transversalement, puis après compression on transforme la fermeture (10) en fermeture étanche et on scelle l'extrémité ouverte (17) du tube.Selon l'invention, on pince la jupe (2) avec des surfaces parallèles (10) serrées élastiquement et on comprime la jupe (2) au droit du produit contenu (7) de façon que le niveau haut de ce produit (7) reste en-dessous ou à la limite inférieure de la fermeture (10), et on scelle la portion (17) d'extrémité du tube (1) qui dépasse de ladite fermeture (10), évitant ainsi toute pollution par le produit dégradant le scellage. L'invention a pour deuxième objet un dispositif de mise en oeuvre de ce procédé. Le procédé et le dispositif de l'invention s'appliquent au conditionnement de produits des domaines alimentaire, cosmétologique, pharmaceutique ou hygiénique.
