A method for manufacturing a container (100) having a covering layer includes: acquiring a preform (200) having a preform covering layer (204) formed by using a synthetic resin having thermoplasticity, the preform being a material for forming a container (100) having a covering layer (104) manufactured by blow molding; setting the preform (200) in a blow mold (310) wherein a blade (440) is provided to a portion of a surface of the blow mold (310) with where the container is brought into contact, the blade having a height that corresponds to a thickness of the covering layer (104); and forming the container (100) having the covering layer (104) by performing blow molding on the preform (200), the covering layer having a slit (190) formed by the blade (440).

An apparatus for forming plastic preforms into plastic containers has at least one supply device with at least one first connecting line, wherein at least one section of at least one connecting line is arranged stationary relative to a main carrier by at least one fastening device, and wherein a section of this connecting line is arranged on a device of the forming device in such a way that, in the event of a movement of the side part carrier relative to the main carrier, this section of the connecting line moves relative to the fastening device. An actuator is arranged on the apparatus, to which at least a section of the connecting line is fastened, wherein this actuator also being movable relative to the main carrier.

A blow molding device includes a nozzle, a pressurized fluid supply source, a seal body, and a rod. The seal body includes a tubular wall. A communication depression extending from a lower end of the tubular wall to a communication port open on an outer circumferential surface of the tubular wall is provided in an inner circumferential surface of the seal body. A communication path is provided in the nozzle. The blow molding device further includes a fluid suction source configured to suck an incompressible fluid from the communication depression through the communication path and the communication port, and/or a pressurized gas supply source configured to supply a pressurized gas that blows off the incompressible fluid from the communication depression through the communication path and the communication port.

A method of forming a container (1) and a container (1) formed thereby. A preform (2), having a generally cylindrical body (60, 8) extending between a closed end (12) and an open mouth, is placed within a mold (20, 22) having surfaces corresponding in shape to the desired container (1). An incompressible medium, which is the end product that remains in the molded container (1), is injected under pressure into the preform (2). Under the influence of the incompressible medium, the preform (2) is expanded into contact with the surfaces defining the cavity, simultaneously forming and filling the container (1). During expanding of the preform (2), portions of the plastic material are forced into a series of recesses (72) defined in the cavity surface (82, 85). With the incompressible medium contained therein, the container (1) is removed from the mold (20, 22) and including a series of raised dots corresponding to the series of recesses (72) defined in the cavity surface (82, 85).

A gaiter seal for shielding a functional element of a container-processing machine extends between parts of a working head of the container-processing machine includes axially-adjacent gaiter modules that extend along an axis and support-and-sliding elements at interfaces between adjacent gaiter modules. The support-and-sliding elements radially support and guide the first and second gaiter-modules along the functional element.
