摘要:
A sealing device for sealing non-circular, in particular polygonal, for example tetragonal, hexagonal, octagonal or elliptical, container openings comprises one or a plurality of induction loops (11, 38, 41) for sealing purposes. Containers (2) comprise joined-on closure devices (3) with sealing discs (15) joined onto a sealing edge (14) of the container opening. The induction loops (11, 38, 41) are adapted to the shape of the sealing edge (14) and the spacing between the induction loop (11, 38, 41) and sealing edge (14) is constantly adjustable and selectable.

The invention relates to an elastic substantially tubular package for a semi-liquid or pasty extractable by a finger pressure product comprising a skirt, a head and optionally a cap, wherein said skirt is formed from a wound foil and is provided with a longitudinal weld seam formed by the overlapping of the edges thereof and the head is fixed to the circumference of the skirt end and forms an oval cross-section at the level of the skirt fixing area. The inventive package is characterised in that the end of the longitudinal weld seam contacting the head is located in or near an area where the radius of curvature of the oval cross-section is minimal.
摘要:
An inkjet printhead having a unitary body with an ink conduit between an ink outlet port of an ink compartment and an ink feed slot compatible with a heater chip has an ink conduit plug laser welded thereto to prevent ink from leaking from the ink conduit as the ink flows from the ink outlet port to the ink feed slot during use. In one embodiment, the ink conduit plug has a lid and an insertion portion. The lid has a laser transparent periphery that becomes illuminated with a laser light to weld an undersurface thereof over an opening of the ink conduit. Techniques for laser welding include an advancing laser beam or a simultaneous welding structure. In another embodiment, the ink conduit plug has two plug sections banded together with either a flexible material or angularly disposed links. The banded plug sections may or may not be laser welded.

The present invention relates to a connecting device (1) for fluid mediums, in particular hydraulic fluid mediums, consisting of a plastic connecting element (2) having at least one connecting section (4) with a receiving opening (6) for a tubular conduit end (8) to be laser-welded. The connecting element (2) consists of at least two components (K1, K2) with different material properties, a first component (K1) surrounding the receiving opening (6) in the area of the connecting section (4) and consisting of a material that is substantially transparent to laser beams.

The invention relates to a method for manufacturing a plastic container, comprising the edge-clamping of a flat, flexible piece forming a curved surface over the inner face of a hollow body, characterized in that the following steps are performed: the edge of the piece is placed in contact with the inner face of the hollow body; a thrust or tensile force is applied to the piece in a direction perpendicular to its surface such as to induce in the piece radial forces resulting in a bringing-together of the edge of the piece against the inner face of the hollow body.
摘要:
In a method for manufacturing flexible plastic containers by two die molds, in the connecting seam of which at least one insert for filling and/or emptying the container is introduced, comprising press faces running perpendicular to the wall of the container, the angle of the press faces is greater than 90.degree., preferable nearly 180.degree. at each locus of connection to the die molds, with regard to the connecting seam of the two die molds.

A cap heat-sealing apparatus for paper containers comprises a vertically movable head, a fixed pressing member provided on the bottom surface of the head, a pair of divided movable pressing members arranged around the fixed pressing member and connected to the head so as to be horizontally movable toward or away from the fixed pressing member, and a heating high-frequency coil attached to the head and surrounding the fixed pressing member. The fixed pressing member has an outer periphery shaped to position along the inner surfaces of heat-sealing container opening edge fitting portions of inverted V-shaped cross section formed at the outer periphery of a square paper cap, which has an aluminum foil layer. The movable pressing members have an inner periphery shaped to position along the outer surfaces of the fitting portions. The high-frequency coil is spaced apart from the fixed pressing member by a clearance for the fitting portions to enter.
