The invention concerns an apparatus for automatically placing a scoop in a container, where the apparatus comprises a scoop supply unit adapted to supply scoops to a release position of the scoop supply unit in a hanging manner, a first gripping device configured to grip an individual scoop at the release position of the supply unit and to move the scoop to a delivery position where the scoop is released from the gripping device in order to place the scoop in a container, where the supply unit comprises two sets of reciprocating holding fingers adapted to release one scoop at a time in the release position, where the gripping device comprises two gripping fingers having a semi-circular shape corresponding to the shape of the scoop, such that the inner sides of the gripping fingers bears on the rim of the scoop. The invention also concerns a method for automatically placing a scoop in a container. The advantage of the inventive apparatus is that one scoop at the time can be picked up and placed in a container in a secure way.

The invention concerns an apparatus for automatic application of lids to containers, said apparatus comprising a rotatable device unit comprising a plurality of circumferentially distributed lid holding members, a lid feeding unit, a glue application unit and a lid application unit. The lid holding members can be directed to each of the units simultaneously by rotating the rotatable device unit. The rotatable device unit further comprises an item application unit configured to fit an individual additional item onto the lid before the lid is attached to the container. The item application unit comprises an item supply unit and at least one movable gripping device configured to grip an individual additional item from the item supply unit and fit the individual additional item onto the lid. The invention also concerns a method for automatic application of lids to containers.

An apparatus and method for sealing an open end of a cardboard-based container containing a powder. A transporter is configured to transport a flow of containers to and from an inductive welding unit. The transporter includes a feeding arrangement to separate the containers and a main conveyor member to convey the spaced containers. A movable gripping arrangement is configured to simultaneously grip at least two containers and simultaneously transfer these containers from the main conveyor member to the welding unit. The welding unit is configured to simultaneously fasten a lid to each of the simultaneously transferred containers.

A machine for applying adhesive on one side of an elongate sheet material, and comprising an adhesive containing trough (19), an adhesive application roller (20) and a driven pressure roller (21). The sheet material (15) is being passed through the nip between said rollers and the width of the rollers surpasses the width of the sheet material. The contact surface of the pressure roller (21) upon the sheet (15), consists of an endless belt (23). The belt (23) runs via at least one guide roller (24) through a trough (25), containing rinsing fluid (25). In said trough the belt (23) runs past at least one further guide roller (27), and past a brush roller (29) which is mounted in the trough (25), adjacent the outer side of the endless belt loop (23). The brush roller is being driven in counter rotation to the direction of movement of the belt. The belt then runs back to the pressure roller (21), so that the section of the endless belt loop which has been driven past the rinsing fluid trough (25) and the brush roller (29), returns to the nip free from adhesive (22).

A method and a device for inspecting a joint such as the joint at the rim of a container. Radiant energy is directed into a small area of irradiation on the joint and the container rim is moved relative to the radiant energy so that the area of irradiation moves in one direction along the rim. Additionally, the area of irradiation is scanned crosswise to the one direction to move the area of irradiation across the width of the joint. Radiant energy reflected from the area of irradiation is detected. This radiant energy indicates the characteristics of the joint. The characteristics indicated by the radiant energy are compared to predetermined set value characteristics to detect product residue or other defects in the joint.

A surface layer is applied to an elongated, deformable hollow profile. The profile originally has at least one wall portion which is curved as seen in cross section. The profile is advanced to a device for applying the surface layer and pressed so as to deform the curved wall portion into a shape which, as seen in cross section, is substantially straight. The surface layer is applied to this wall portion while it is in the substantially straight shape, and the profile is then at least substantially returned to its original shape.

An easy openable closure device for a packaging container, comprising an outer layer, for instance injection moulded of plastics, and an inner layer possibly comprising several sublayers and such that it gives the closure device a specific characteristics as to welding possibilities, gas barrier and light barrier. A first tearing denotation is arranged in the outer layer and merges into a second tearing denotation under a tangentially acute angle, said second denotation extending circumferentially around the closure device. At both sides of the circumferential tearing denotation, the inner layer is sealed to or connected to the outer layer. In the outer layer there is arranged an element having a portion for penetrating the first tearing denotation in the outer layer inside the said sealing region. The strength of the second tearing denotation is lower than the sealing strength between the layers and the latter strength is higher than the tearing strength of the inner layer.

Radiant energy is directed into a small area of irradiation on the joint and the container rim is moved relative to the radiant energy so that the area of irradiation moves in one direction along the rim. Additionally, the area of irradiation is scanned crosswise to the one direction to move the area of irradiation across the width of the joint.

The characteristics indicated by the radiant energy are compared to predetermined set value characteristics to detect product residue or other defects in the joint.

A method and a device for scrap-free manufacture of coated profiles and thermoformed containers. A hollow pipe having a cross-section suitable for the desired profile is extruded. The extruded hollow profile is cut longitudinally. Thereafter the profile is planar laminated by a web formed material having desired characteristics. The cut, laminated profile thereafter is formed into the original shape thereof, or another suitable shape, and is formed into container casings. When thermoforming containers, a hollow profile is extruded from a thermoformable material in an extruder, this hollow profile is cut, in one or several longitudinal cuts. In web or roller form such cut profile is supplied to a so called scrap-free thermoforming machinery, where the thermoformed containers are manufactured.
