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:
A tube or other container for storing and dispensing a product such as toothpaste, a lotion, a cream, etc., includes one or more creases. Initially, each crease can be in a contracted position, where the tube has a first volume when the crease is in the contracted position. Due to outgassing of the product and/or other factors, pressure may increase within the sealed tube. In response to the pressure increase, the one or more creases can deflect from the contracted position to an expanded position, where the tube has a second, increased volume when the crease is in the expanded position. Deflection of the one or more creases effectively increases the volume of the interior of the tube, and maintains pressure within the tube at a desirable level.

A handheld antiseptic dispensing applicator device having a reservoir for storing an antiseptic agent, the reservoir being coupled to an applicator pad, and a defeatable membrane or barrier being interposed between the reservoir and the applicator pad. Embodiments of the device comprise a squeezable reservoir, wherein the internal hydraulic pressure of the squeezable reservoir is increased via user applied forces to thereby defeat the membrane releasing the antiseptic agent contained therein which is then absorbed by the applicator pad. The defeatable barrier or membrane is also removable or may be defeated in connection with other mechanisms according to various embodiments.

The invention provides tube-filling machines and methods for, in such machines, filling double tubes (10), that is to say the tube type which has concentric packing tubes (11, 12) which are connected to a common tube shoulder (13) provided with a dispensing opening. For filling the gap-shaped space between the inner tube and the outer tube, an elongate filling nozzle (18) is quipped on its output end with a peripheral set of filling pipes (18f) with output openings located radially inwardly in relation to the lateral surface of the filling nozzle and of smaller diameter than the gap. Located inside the filling nozzle is an elongate mandrel (20) of male type, and located on the outside around the open end of the outer tube is a centring sleeve (19) which maintains its position relative to the outer tube throughout the gap space-filling procedure.

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.
