Abstract:
The invention relates to a device and a method for producing plastic moldings from at least two different sub-elements (15; 16) that includes first and second mold halves (3) and a rotatable center block (6) with center and third mold halves (8; 17) interposed therebetween. The center and third mold halves define first and second parting planes with the first and second mold halves. First cavities are defined in the first parting plane, into which a first plastic component is introduced to produce preforms (12). When the first parting plane is opened, the performs (12) remain on the center mold halves (8) and are brought into the second parting plane when the center block (6) is rotated, in which second parting plane second cavities are at least partially defined by the preforms (12), into which a second plastic component is introduced and first sub-elements (15) are produced. Second sub-elements (16) are produced in the additional cavities. When the second parting plane is opened, the sub-elements (15; 16) remain on the center and third mold halves (8) and are rotated into a lateral assembly position when the center block (6) is rotated.
Abstract:
An apparatus for forming a container generally comprises a first mold part having an injection mold portion and a blow mold portion and a second mold part having a core pin. The core pin is configured to cooperate with the injection mold portion in a first position to define an injection mold cavity for forming a preform and an integral cap. The core pin is also configured to cooperate with the blow mold portion in a second position to define a blow mold cavity for forming a receptacle from the preform. The cap may be closed at the blow mold portion to seal the receptacle. One or more threads may be formed on a neck of the container.
Abstract:
The present invention discloses a mold core for manufacturing a container closure comprising a plurality of slides, a sleeve placed over the plurality of slides, a slide seat on which the plurality of slides are mounted, and a cam device arranged inside a space defined by the plurality of slides. The plurality of slides comprise a plurality of first independent slides and a plurality of second independent slides, wherein each of the first independent slides and each of the second independent slides are configured to be individually mounted on and individually detached from the slide seat; and wherein axial movement of the sleeve relative to the first independent slides and the second independent slides effects application of radial force onto the first independent slides and the second independent slides successively, so as to cause successive inward movement of the first independent slides and of the second independent slides within the sleeve. Since the plurality of slides of the present invention comprise a plurality of independent slides, therefore the mold has a simple structure, is easy to maintain and replace, and has low maintenance and replacement costs.
Abstract:
A device for applying a sealing compound into a closure cap for containers comprising: an outer stamp (18) and a concentric inner stamp (14), the stamps being movable with respect to each other, an annular gap (26) between the stamps (14, 18), which is open towards the outside or the inside and of which at least one section is variable between an initial gap width and a gap width zero in the movement direction of the stamps in an axial relative movement of the stamps (14, 18), a feeding system for plasticized sealing compound within a stamp, which is connected to the annular gap (26), a mechanism that prevent any reflux of the melt from the annular gap, and adjustment mechanism for at least one of the stamps for changing the gap width of the annular gap.
Abstract:
A method of manufacturing a composite closure, including an outer closure cap and an inner sealing liner, comprises providing a closure cap having an annular skirt portion including an annular lip that defines an annular recess adjacent a top wall portion of the cap. Molten plastic is compression molded within the closure cap to form the inner sealing liner adjacent the top wall portion, with the periphery of the sealing liner positioned within the annular recess of the closure cap. A plurality of circumferentially spaced gussets are provided within the annular recess for controlling the flow of the molten plastic during liner formation, thereby facilitating the venting of air to abate formation of voids in the sealing liner.
Abstract:
A single point hinge and a method of thermoforming a plastic container including a single point hinge include a lid, a tray, a single point hinge connecting the lid and the tray. The single point hinge includes an angle formed by a lid chamfer and a tray chamfer. The single point hinge further includes a lid well adjacent to the lid chamfer and a tray well adjacent to the tray chamfer, and the lid connects to the lid well and the tray connects to the tray well.
Abstract:
The closure cap according to the invention for a container for receiving liquids, and in particular a BFS container for receiving an enteral nutrient solution, has a cover part and a rim part, with a withdrawal part for the withdrawal of a liquid, and in particular the enteral nutrient solution, being arranged in the cover part. Basically, the closure cap according to the invention may also comprise, as well as the withdrawal part, an injection part for the injection of a medicinal liquid into the enteral nutrient solution. The withdrawal part of the closure cap according to the invention has a connecting part for a spike of a flexible line of a transfer device and a closing-off part having a pierceable membrane for closing-off the recess in the connecting part.
Abstract:
The invention is a method for preparing a finished part in a mold wherein the finished part includes n mold inputs, the method comprising the steps of (a) providing a mold having n mold stations, (b) simultaneously adding a mold input at each mold station to create a finished part and n−1 part portions, (c) removing the finished part and each part portion from each mold station, (d) transferring the finished part to a finished part holding area and transferring each part portion to a different mold station, and (e) repeating steps (b) through (d).
Abstract:
A method of making an inverted-hook groove for a plant fiber-molded cup lid is to form an inverted-hook groove on a side surface of a plant-fiber molded cup lid, which has already been thermally compressed and shaped, processed and shaped once more to form an inverted-hook groove at the side surface of the molded cup lid so that the molded cup lid with the inverted-hook groove can be tightly and closely combined with the upper edge of a primary cup body. The method of making an inverted-hook groove for a plant-fiber molded cup lid of this invention is classified into three kinds; a method of compression shaping directly, a method of roller compression shaping and a method of air bag compression shaping.
Abstract:
Disclosed is a method for preparing an air channel-equipped film for use in vacuum packages, which comprises the step of providing a gas-impermeable base, along with a melt-extruded heat-sealable resin, to a laminating unit consisting of a laminating roll and a cooling roll, to form a heat-sealable resin layer on the gas-impermeable base, characterized in that the heat-sealable resin is molded and quenched in such a way that a plurality of protrusions, corresponding to a plurality of grooves formed in a predetermined pattern on the circumferential surface of the cooling roll, are formed on the molded heat-sealable resin layer, defining channels for the evacuation of air therebetween. The method is simple because of its ability to form air channels without the aid of additional embossing techniques, as well as being economically favorable owing to the employment of no embossing molds.
