A contact lens package includes a first package layer, a second package layer, a lens receiving area defined between the first and second package layers, and first and second seal portions. The first seal portion extends around a first portion of the lens receiving area. The second seal portion extends around a second portion of the lens receiving area. The second seal portion has different sealing properties than the first seal portion. The first seal portion may include a releasable seal between the first and second package layers, and the second seal portion may include a permanent seal between the first and second package layers.

This method for producing a packaged food product portion includes the following steps: providing a cup defining an inner area for receiving the food product; cold pouring, at a temperature below 50° C., the food product into the receiving area of the cup; covering the food product using a thermally insulating lid arranged such that thermally conducting flaps of the cup extend toward the outside of the lid after the covering step; folding the flaps on an outer face of the lid opposite the receiving area; and heat-sealing the flaps on the outer face.

A former assembly (10) including a base (11) to which there is attached a frame (12) that supports a sleeve (13). The sleeve (13) encloses a generally upwardly extending passage (14) to which product is delivered in batches from a weighing machine. Fixed to the internal surface (20) of the former shoulder (15) are heaters (24) that heat the external surface (16) over which the film bag material passes to be heated thereby.

The invention relates to a method for wrapping and sealing a flexible sheet over an insert (10) to produce a pack (100) for preparing a food or beverage product from one or more ingredients; the pack comprising an insert (10) and a container (20) made from the flexible sheet folded to store the one or more ingredients, the flexible sheet being arranged overwrapping and matching the shape of the insert (10) in its entirety except for the part of the insert (10) in direct communication with the inner volume of the container (20); the method comprising the following steps: —holding the insert (10) so that it is substantially perpendicular with respect to the flexible sheet; —moving the insert (10) towards the flexible sheet, until it touches a bottom sealing tool (210); —moving at least two side sealing tools (220, 230) towards the insert (10); —applying by the bottom sealing tool (210) and by the side sealing tools (220, 230) a certain required pressure and temperature to achieve a tight sealing of the flexible sheet over the entirety of the insert (10) except for the part of it in direct communication with the inner volume of the container (20). The invention further relates to a device (200) for wrapping and sealing a flexible sheet over an insert (10) to produce a pack (100) for preparing a food or beverage product from one or more ingredients.

The sealing device includes a heatable base plate that cooperates with a heatable split plate to simultaneously form three intersecting seal lines. The split plate includes an alpha plate and a beta plate. The alpha plate and the beta plate each include a first heated surface that cooperate with the base heated surface to form a pair of co-linear seal lines. In addition, the alpha plate and the beta plate each include a second heated surface that cooperate together to form a third seal line that extends in a direction perpendicular to the co-linear seal lines and intersects the co-linear seal lines. A method of forming a complex seal joint is also described.

A waveguide segment with two sub-segments including a first sub-segment with a first wall and a second wall, each having an inner face by which laser light can be reflected. The inner faces are opposite to each other and a depth of the sub-segment is defined by a distance between the first and the second inner face. Further, each wall has an exit side, and an opposite entry side, a height defined by the distance between the exit and the entry side and a width. At least part of the entry side of each wall extends in an angle to the height, for which applies: 0°<α<90°. The second sub-segment may be formed complementary and the second sub-segment has a portion at the exit side of each wall. Laser light passing through the second sub-segment enters the first sub-segment between the first and the second portion.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

A protrusion on a first member made of synthetic resin wherein a laser beam is applied to a side surface of the protrusion in a state in which a top surface of the protrusion of the first member is abutted against a second member made of synthetic resin, so as to melt at least the entire top surface of the protrusion and melt a portion of the second member in contact with the protrusion by heat of the melted top surface of the protrusion, followed by solidification of the melted portions, whereby the first member and the second member are welded together.

A process for joining two sheeting articles reinforced with unidirectionally aligned endless-fibres by ultrasonic welding, wherein the fibres are embedded in a matrix of polycarbonate and the sheeting articles have abutting ends that are substantially rectangular and substantially even. The process comprises (1) arranging the sheeting articles next to one another end-to-end in the region of the abutting ends in a welding apparatus between a sonotrode and an anvil, (2) welding the sheeting articles by means of ultrasound, wherein the sonotrode and the anvil exert pressure on the to-be-welded sheeting articles in the melting region between the sheeting articles and perpendicularly to the abutting ends of the sheeting articles, and (3) removing the sheeting articles that are welded to one another from the welding apparatus. Also provided is a second process for joining two sheeting articles, a sheeting article, an apparatus, and a multilayer composite.

Structure for reducing sloshing noises, said structure being provided for disposal in a liquids container for a motor vehicle, having a random arrangement of mutually interlinked threads, wherein a plurality of the threads at least in portions are connected in a materially integral manner to at least one or a plurality of further threads of the structure, wherein the structure has at least one side in the region of which a planar cover of the random arrangement of mutually interlinked threads is provided at least in portions.
