A container or consumable like a reaction tube for use in diagnostic assays. The present disclosure provides a system for fluid handling and transport, comprising a plate with at least one cavity for receiving a fluid which is surrounded by a rim, and a separate cover comprising a centrally arranged surface as a sealing element which is surrounded by a rim, wherein the plate or the cover comprise at least one snap-fit mechanism for connecting at least two plates, at least two covers or a plate and a cover, wherein the snap-fit mechanism extends upwards or downwards from the surrounding rim of the plate or the cover, and wherein the rim of the plate or cover which is to be connected is configured for accommodating the snap-fit mechanism of an upper or lower plate or cover in a retaining element arranged at the rim.

A method for producing a package which has a formed part with a product cavity, and a lidding film covering the product cavity. According to the method, a seam is defined, the seam is divided into sections, a pull-off force for pulling the lidding film from the formed part at least for a first section is determined, and the lidding film is sealed to the formed part. The sealing temperature for the first section is selected based on the pull-off force.

A package that is suitable for packaging an article for collecting or administering a pharmaceutical active substance is disclosed. The package includes a first packaging component that includes a product-contacting sealant layer that includes a first ethylene vinyl alcohol copolymer. The package includes a second packaging component that includes a product-contacting sealant layer that includes a second ethylene vinyl alcohol copolymer. The ethylene content of the second ethylene vinyl alcohol copolymer is equal to or less than about 38 percent and the ethylene content of the first ethylene vinyl alcohol copolymer is greater than the ethylene content of the second ethylene vinyl alcohol copolymer.

A machine for manufacturing a mask includes a plurality of carriers mounted to a belt so as and having a plurality of molding cavity inserts. A feed station supplies material from a roll so as to form a sheet of material on to the carriers. A shell forming station is configured to press a molding core inserts into the molding cavity inserts so as to form a shape of the mask. A welding station generates a predetermined ultrasonic vibration at a predetermined frequency and a predetermined amplitude so as to weld the sheet of material. A cutting station cuts out the mask from the sheet of material. A mask grabbing apparatus is configured to grab the mask and position the mask for retrieval.

A first thermoplastic component and a second thermoplastic component including a first joint portion and a second joint portion, respectively, are provided. A least a portion of a surface area of each of the first and second joint portions include a respective first and second mating surface. The first and second mating surfaces of the respective first and second joint portions are positioned in contact with one another. The first and second joint portions are fusion joined. Fusion joining the first and second joint portions forms a fused unitary portion of the first and second thermoplastic components.

A method of producing a golf ball applies ultrasonic welding on two half shells to form at least one intermediate layer, at least one cover layer, or at least one intermediate layer and at least one cover layer. The ultrasonic welding may include pressing the two half shells together, delivering a high power electrical signal to a welding stack, and converting the high power electrical signal at the welding stack to ultrasonic energy. The converting may include converting the high power electrical signal into a mechanical vibration, modifying an amplitude of the mechanical vibration to generate a modified mechanical vibration, and applying the modified mechanical vibration to an interface of the two half shells to weld them together ultrasonically. Aspects also relate to golf balls, or one or more layers thereof, made using ultrasonic welding.

A device for sealing sample tubes comprises a tool assembly configured to interface with a rack holding a plurality of sample storage tubes, the tool assembly holding a plurality of punches and a die plate including a plurality of cutting holes, with each of the plurality of cutting holes accepting one of the plurality of punches. The tool assembly receives a foil sheet between the punches and the die plate. The device includes an actuator enabling linear movement of the tool assembly. Linear movement of the tool assembly towards the rack engages the die plate against the rack and punches the punches through the cutting holes of the die plate to punch a plurality of sealing sections from the foil sheet and to press and seal each of the sealing sections against a top end of each of the plurality of sample storage tubes in the rack.
