In some embodiments, apparatuses and methods provided herein are useful for dispensing a fluid, such as a thixotropic fluid. In some embodiments, a bottle having a closure cap includes a flip top, a base, and a disk, where the base and disk define a mixing chamber configured to facilitate mixing of any serum or liquid separated from the fluid back therein. In some configurations, the base has a central opening through which the fluid exits and an internal shaft with a non-planar end surface opposite the central opening. In some configurations, the non-planar end surface and the disk define channels between the mixing chamber and the internal shaft. In some embodiments, the disk includes a central opening, a plurality of partial annular openings through a planar surface of the disk, and projections extending into the mixing chamber.

A welding device for the sealing welding of thermopolastic hoses (184), includes a clamping device (12) with at least two clamping jaws (122, 124), of which at least one is movable and between which a hose (184) which is to be welded can be clamped, wherein the clamping device (12) has a heating devices (38; 40; 64) which is coupled to a control unit (30) and is configured to heat the hose clamped between the clamping jaws (122, 124). The invention is distinguished in that the at least one movable clamping jaw (122) is actuable with a controllable, bidirectional actuator (32, 34; 42-52; 54, 56, 58) which is coupled to the control unit (30) in such a manner that the clamping pressure acting on the hose (184) can be adjusted independently of the heating device.

A tail sealing method of a tube container and a product thereof, which achieves tail sealing and covering of an end surface of a mid-layer material of the tube container at the same time, so as to protect the mid-layer material. The tail sealing method includes the steps of: (1): placing a tube body into a tail sealing machine; aligning a left mold and a right mold of the tail sealing machine with an end opening of a tube tail of the tube body, and then closing the left mold and the right mold against each other; surfaces of the left mold and the right mold opposite to each other are each provided with a pressing portion, which is configured to press against the end opening of the tube tail of the tube body; a first protruding edge is horizontally arranged along a lower edge of each pressing portion; (2) fusing two sides of the end opening of the tube tail of the tube body together with high pressure by the left mold and the right mold of the tail sealing machine; an overflow portion is formed at a tail portion of the tube tail by melted material of the tube body pushed towards the tail portion of the tube tail by the first protruding edges; (3) after cooling the tube tail, trimming the overflow portion at the tail portion of the tube tail with a cutter, thus completing a tail sealing process; wherein the cutter performs cutting at a position higher than an end of the tube body corresponding to the tube tail.
