摘要:
On a band-shaped male-side base (211A) on which a male part (212) is integrally provided and a female-side base (221A) on which a female part (222) is integrally provided, a light-absorbing layer (23) and a bonding layer (24) are laminated on the surface opposite to the surface on which the male part (212) or the female part (222) is provided. The light-absorbing layer (23) contains a light-absorbing material that absorbs laser light with a wavelength absorption region of 800 nm to 1200 nm. The bonding layer (24) contains a metallocene straight chain low density polyethylene, which is a low melting point resin with a melting point of 60°C to 120°C. When bonding the zipper tape (20) to a substrate film (11), the light-absorbing layer (23) is heated by irradiating laser light and the bonding layer (24) melts. The melted bonding layer (24) is pressed on the substrate film (11) and bonded. Bonding without thermal degradation of the substrate film (11) is possible.

Breakable spout (100) of the present invention individually comprises spout body (110) and cover (160) that covers an outer circumference of spout body (110). Spout body (110) comprises cylindrical part (120) that has a center hole that serves as a flow channel (111) and breakable part (150) that is breakable at the tip end of cylindrical part (120). Cylindrical part (120) has a first protrusion (123) on an outer circumferential surface thereof. The cover has second protrusion (161) on an inner circumferential surface thereof. Second protrusion (161) engages first protrusion (123) when cover (160) is fitted to spout body (110) such that spout body (110) is covered with cover (120) from the tip end side of cylindrical part (120). Cover (160) covers spout body (110) and is secured when the first protrusion (123) engages the second protrusion (161). Opening (169) is formed in the portion of cover (160) that corresponds to communication hole (155) of annular part (154) when cover (160) is fitted to the spout body and covers spout body (110).

Das Verfahren umfasst zumindest die Schritte Bereitstellen eines Basismaterials, Erzeugen wenigstens einer Ausnehmung (190) in dem Basismaterial mittels wenigstens eines Trennverfahrens aus der Gruppe Laserschneiden und Fräsen und zumindest bereichsweises Füllen der wenigstens einen Ausnehmung (190) mit einem elektrisch leitfähigen und/oder magnetischen Material. Die Erfindung betrifft weiterhin ein entsprechendes Substrat (60) sowie eine Verpackung (10) aus einem solchen Substrat (60).
摘要:
Shown and described are a device for the liquid-tight sealing of two partially overlapping packaging parts (10, 11), wherein one is a tubular main body (10), in particular formed by a blank of composite cardboard/plastics material, and another packaging part (11) forms the top or bottom of the packaging, comprising at least one pin (D) and a die (M), wherein the pin (D) has at least two spreading elements (1A, 1B, 1C, 1D), which are moved out of their working position towards one another into a rest position to reduce the cross section, in order to allow the tubular main body (10) to be easily pushed on, and a corresponding method and a container produced therewith or thereby. With the aim of achieving the effect that the tubular main body (10) can be easily pushed onto the pin (D) or pulled off from it and with the desire for a construction that is simple but reliable and undergoes little wear, it is provided that the spreading elements (1A, 1B, 1C, 1D) have sealing jaws (2A, 2B, 2C, 2D), which in their working position form an uninterrupted peripheral outer contour (AK), which corresponds to an inner contour (IK), formed by an opening in the die (M), in such a way that between the inner contour (IK) and the outer contour (AK) there remains a narrow annular gap for applying a pressing force from the inside to the overlapping region (12) of the packaging parts (10, 11).
摘要:
In an apparatus for successively making plastic bags, a laser beam irradiator (5) irradiates laser beam (6) onto webs of panel material (2) and a body of zipper material (3) to heat and melt the webs of panel material (2) and the body of zipper material (3) with the laser beam (6). The webs of panel material (2) and the body of zipper material (3) are fed intermittently at a speed V predetermined to be changed by time T. The irradiator (5) is controlled on a feedforward control basis for the laser beam (6) to be regulated in amount Q, the amount Q being calculated from the speed V predetermined, to obtain a calculated value of amount Q. The laser beam (6) is regulated in accordance with the calculated value to heat and melt the webs of panel material (2) and the body of zipper material (3) uniformly irrespective of the speed V being changed.
