[Object] Provided is a tube joining device which is capable of preventing occurrence of a joining failure caused by a setting error of tubes in advance, and in which tube holding and release of the holding are realized by a simple device configuration.

[Solving Means] A tube joining device 1 includes: a first tube holding portion 160 that is capable of holding a first tube T1; a second tube holding portion 230 that is capable of holding a second tube T2; a tube superimposing portion 30 that disposes the first tube and the second tube in a superimposed manner; and a switching mechanism 240 that is capable of switching holding of the second tube by the second tube holding portion and release of the holding. The switching mechanism applies a biasing force for maintaining a state in which the second tube is held to the second tube holding portion, and applies a biasing force for maintaining a state in which the holding of the second tube is released to the second tube holding portion in accordance with relative approaching of the tube holding portions.

A method is described for opening a heat bonded sterile connection that includes a skin of material blocking flow between the connection site. The method includes applying external pressure to the connection site.

The invention is about an ultrasonic welding-based microfluidic device. It is mainly made of a first element and a second element welded one to the other via at least one structure (10, 10). The structure (10, 10) comprises an elongated welded portion for said welding, a welding channel (12, 12) extending between the first and second elements and along one side of the welded portion, and a draining channel (13) communicating with the welding channel (12, 12) and the microfluidic path (20, 20) of the device. The invention is further about a method of manufacturing such a device.

A connection including a first profile having a first end and a first lumen, the first profile including a first polymeric material and a second profile having a second end and a second lumen, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently welded via an ionized gas treatment.

The present disclosure relates to a method for producing an oral pouched snuff product comprising a filling material (29, 10) and a saliva-permeable pouch (43) enclosing the filling material (29, 10), the product (29, 10) having a moisture content of at most 20% by weight, in particular at most 10% by weight, based on total weight of the product (29, 10), the saliva-permeable pouch (43) having one or more seals (45, 46), and said filling material (29, 10) comprising at least 20% by weight, based on dry weight of the filling material (29, 10), of at least one ingredient having a melting temperature below 180 C., the method comprising ultrasonically welding and cutting an advancing web (32) of packaging material (7) to which the filling material (29, 10) has been supplied. The present disclosure also provides an oral pouched snuff product which is obtainable by this method.

A system for checking a package body with an image is capable of automatically judging good or bad product of manufactured package bodies and automatically performing change of production conditions in a filling and packaging machine, and includes a filling and packaging machine, an image data judgement system, a storage device and an image data analysis system, wherein the image data judgement system is provided with an imaging device for shooting a package body, a storage unit for storing judgement condition on good or bad package body, a judgement unit for judging good or bad package body and an image data transmission unit for transmitting the image data shot by the imaging device to the storage device.

A structure method accurately detects biting of a foreign object in a packaging machine. A control apparatus controls a packaging machine that sequentially seals and/or cuts a packaging material transported in a first direction using a rotor. The rotor is arranged to have a tangent to its outer circumference portion in contact with the packaging material extending in the first direction. The rotor is drivable and rotatable by a driver. The control apparatus includes an information obtaining unit that obtains information indicating a rotational position of the rotor and a status value of the driver in predetermined cycles, and a determination unit that determines a presence of an abnormality in a sealed portion of the packaging material using, from the information obtained by the information obtaining unit, a status value of the driver corresponding to a rotational position of the rotor falling within a predetermined range or being a predetermined position.

An ultrasonic sealing apparatus for paper packages achieves more stable ultrasonic sealing by cooling the horn during ultrasonic sealing which would otherwise be unstable due to heat imparted to a horn by continuous sealing. An end portion of a horn of a casing that includes the horn and a converter, or the horn, a booster and the converter is cooled by supplying air to a frame portion exposed toward an anvil side.

An anvil is provided in an ultrasonic sealing machine, in which vibration applying surfaces of a pair of horns and an abutment surface on an end face of the anvil cooperate with each other to bond a laminate. The abutment surface includes left and right welding surfaces which are disposed in the extending direction of the vibration applying surface and protrude toward the horns to face two vibration applying surfaces. The left and right welding surfaces each have an area per unit length in the extending direction, which continuously or step-wisely increases with an increase in distance from a center of the seal area, which is a region where the two vibration applying surfaces are adjacent to each other.
