Stretch-blown plastic container with a handle region made integral and method of production for the plastic container
A stretch-blown plastic container, includes a container body which encloses a filling volume with a container bottom; a container neck which adjoins an opposite end of the container body, having a container opening and an integrated handle region, the handle region being hollow and joined to the filling volume which is enclosed by the container body; and between the handle region and the container body, a through opening recessed and bordered over its entire periphery by wall parts of the container body and of the handle region which have been welded to one another.
MEANS OF STERILIZING THE STRETCHING MEANS OF A CONTAINER MOLDING DEVICE, AND CONTAINER MANUFACTURING INSTALLATION
The present invention relates to an installation for manufacturing containers made of thermoplastic material, having a sterilizing mode and a production mode. The installation comprising a molding machine, a transfer means, and a decontamination device. The molding machine is equipped with at least one molding device having stretching means, and the molding device is designed to manufacture by stretch blow molding said containers from preforms when the installation is in production mode. The transfer means conveys the manufactured containers between the molding machine and a second downstream machine when the installation is in production mode. The decontamination device introduces the sterilizing agent into at least one sterilizing preform during the sterilizing mode. The installation further comprises removal means that can be actuated in sterilizing mode to remove the hollow bodies from the transfer means upstream from the second machine.
Base for an accessory and tank accessory, method for producing a tank
A base made from plastic material for a motor vehicle tank accessory, including protrusions to be welded to a preform during production of the tank by blowing the preform, wherein: the base includes a solid surface recessed from the protrusions, the solid surface including a part without protrusions and a part taken up by the protrusions, the area of the part of the solid surface without protrusions is at least equal to one times the area of the solid surface taken up by the protrusions, the height of the protrusions relative to the solid surface is between 0.6 mm and 0.8 mm.
Decontamination device and method
A method for decontaminating a tube of which a first open end forms an inner neck towards the inside of the tube and an outer neck towards the outside of the tube, the method including: initially raising the temperature of the tube, then subjecting the tube to ultraviolet radiation, that includes emitting ultraviolet radiation by radiation emission apparatus, and subjecting the inside of the tube, the outer neck and the inner neck to the ultraviolet radiation, in which the first end is inserted into a cavity arranged to reflect the ultraviolet radiation emitted by the emission apparatus and to direct this ultraviolet radiation into the tube through the first end, onto the outer neck of the tube and onto the inner neck of the tube.
Methods of forming unitary serological pipettes
A method for producing pipettes (110, 111, 112) is provided. The method includes extruding a polymer melt into at least one mold segment of a mold assembly (120) having a plurality of mold segments to form a parison (50) or preform, wherein the plurality of mold segments (122) comprise cavities (42) that are shaped to form pipettes when in communication with the cavity of an adjacent mold segment; forming at least two pipettes in the shape of the mold segment cavities by blow-molding or vacuum forming the parison or preform, each of the at least two pipettes having proximal and distal ends; heating the pipettes to form a locally heated portion of the at least two pipettes; and separating the pipettes by cutting the locally heated portion of the at least two pipettes with separation feature (64, 66, 194, 196).
CONTENT FILLING SYSTEM AND VERIFICATION METHOD OF CONTENT FILLING SYSTEM
A preform is sterilized by a preform sterilizer. The preform is blow-molded by a blow-molding device to manufacture a container. Next, the container is filled with a culture medium by a filling device without sterilizing the container by a container sterilizer, and the container is plugged by a plugging device. Thereafter, it is verified how much microorganism survive or propagate in the culture medium in the container. A degree of sterilization in the container sterilizer is adjusted on the basis of a verification result.
Means of sterilizing the stretching means of a container molding device, and container manufacturing installation
The present invention relates to a method for sterilizing stretching means (12) of a container moulding device (10) fitted to a plant for manufacturing thermoplastic containers obtained by stretch-blow-moulding from production preforms, the said method for sterilizing the stretching means (12) comprises at least the steps consisting in: —introducing a determined quantity of a sterilizing agent into a sterilization preform (30), —during a step referred to as a conversion step, converting said sterilization preform (30) into a hollow body (50) by stretching—blowing into the said moulding device (10), said introduction of the sterilizing agent being performed in the vapour state in a sterilization preform (30) at a temperature that allows a uniform film of mist to be deposited by condensation onto an internal surface (32) of said sterilization preform (30), and in that at least two sterilization preforms (30) are then converted successively into hollow bodies (50) in the one same moulding device (10).
METHOD FOR CODING A CONTAINER AND CODED CONTAINER
The invention relates to a method for coding a dimensionally stable packaging container or an associated component made of a plastics-based and/or paper-based material composition, the packaging container being suitable for storing consumer goods such as food, washing agents, etc., wherein, during a shape-forming process for forming the three-dimensional packaging container or the associated component by means of a shaping tool mold, at least one outer and/or inner side undergoes, in at least one position, a shape-changing treatment acting on its first surface in order to produce at least one three-dimensional code.
Blow molded part including compression molded element
In one example, a structure is provided that includes a plastic body having a unitary, single-piece construction. The plastic body further includes a substantially hollow interior, and a parting line that extends around a portion of the perimeter of the structure. The structure also includes a solid compression molded element that is integral with the plastic body. The solid compression molded element is configured and arranged such that the parting line is not connected to the solid compression molded element.
