Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning the push-up portion from the first position to a second position under a mechanical force.

Post mold manufacturing container having an integral collapsible spout
11458667 · 2022-10-04 ·

A method of post mold manufacturing a container having an integral collapsible spout molded in an extended position with flashing surrounding the integral collapsible spout. An outflow transporting means is moving the container from a blow molding machine to a trimming finishing station where flashing is removed and the container trimmed to specifications. The container is then transported to a spout collapsing station with integral collapsible spout in the molded extended position where it is compressed to a fully collapsed position. This process is completed while the material used in molding the integral collapsible spout is thermally pliable, permitting the integral collapsible spout to be transformed from the molded extended position, to the fully collapsed position.

CONTENT FILLING SYSTEM AND VERIFICATION METHOD OF CONTENT FILLING SYSTEM
20220185645 · 2022-06-16 · ·

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.

The invention relates to a breathable film. The specific ball-drop impact resistance of the film is more than 100 mm per gram polymer per square meter. The film has a water vapor permeability of at least 1000 g/m2 in 24 hours. The elongation at break of the film in the machine direction is less than 200%.

VERTICAL DISPLACEMENT DEVICES AND METHODS FOR MECHANICALLY INVERTING A THERMOPLASTIC CONTAINER BASE
20220089310 · 2022-03-24 ·

A displacement device for moving a truncated cone at a base of a container from an as-blown position to a displaced position. The base includes a deep base ring between a standing surface and the truncated cone. The displacement device includes a collar sized and shaped to be received within the deep base ring. A plunger includes a head at an end of a shaft extending through the collar. The head is sized and shaped to be received within the receptacle of the collar. The plunger is movable from a retracted position, at which the head is seated within the receptacle, to an extended position at which the head extends out from within the receptacle to allow the head to contact the truncated cone and move the truncated cone from the as-blown position to the displaced position.

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.

CONTAINER AND METHOD OF MANUFACTURE

A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article. The intermediate article is trimmed to form a finished container. The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive. Finished containers are disclosed.

BLOW MOLDED PLASTIC CONTAINER WITH INTEGRATED SPOUT
20220073230 · 2022-03-10 ·

A plastic container having a main body defining an interior space and a finish defining a mouth in fluid communication with the interior space. The finish has a substantially cylindrical circumferential wall of generally uniform thickness surrounding the mouth. The circumferential wall has an upper edge with a perimeter flange and a pair of tabs projecting radially inward from the circumferential wall, the tabs defining a spout therebetween. The container is made by disposing a plastic material suitable for a blow molding process within a mold cavity, the mold cavity being configured to form a hollow blow-molded article comprising the main body and the finish as described with a moil portion extending from the perimeter flange in a direction opposite the main body. The container is made by further inflating the plastic material within the mold cavity, and removing the moil portion. The blow-molded article is also disclosed.

CONTAINER AND METHOD OF MANUFACTURE

A method for manufacturing a container includes injecting a first material into a first mold to form a top portion of a preform. The first material and a second material are injected into the first mold to form a bottom portion of the preform. The preform is disposed in a second mold. The preform is blow molded into a finished container.
