Abstract: In a plastic container manufactured by melting blow molding a heated and molten parison extruded from an extruder, a mouth 3 and/or a specified part of a body 2 has a thicker thickness than the body proper. One or more thick parts of the body 2 are continuously or discontinuously formed over part or all a peripheral, height or helical direction of the body of the container. The container enjoys enhanced rigidity, appearance and functionality even when the thickness of its body is considerably reduced.

Abstract: A bottle having a modified neck and intended for use with a child-resistant closure which allows the user to open the bottle without removing the closure completely from the bottle is described. The neck includes at least one locking lug and at least one anti-removal ring. The anti-removal ring is positioned between the lug and the open end of the neck. The neck may further include at least one deformation recess, with the deformation recess being adjacent to and radially offset from the locking lug. The ring and recess are intended to deter the user from bypassing the child-resistant safety features of the bottle and removing the closure completely from the bottle.

Abstract: This invention comprises the heat- and pressure-resistant PCO neck obtained by utilizing the PCO (plastic closure only) neck structure and giving the heat resisting property to the PCO neck to obtain the heat-resistant PCO neck that will make a great deal of resources saving a reality. The heat-resistant PCO bottleneck comprises the round neck wall 2 having the same outer and bore diameters as the corresponding neck wall 21 of the heat-resistant neck 20; the thread ridge 3 of a continuous thread structure; the thread ridge extension disposed so as to keep a fixed distance from the top edge of the mouth and extending over the distance that corresponds to a wide central angle; and a bead ring 5 and a neck ring 7 molded in the same shapes as those of the PCO bottleneck 10. The bottleneck thus obtained causes no irregular shrinkage deformation and demonstrates high heat-resisting property and a sufficient resources-saving effect when the entire bottleneck is thermally crystallized and whitened.

The bottle is formed by biaxially stretch-blow-molding a thermoplastic resin, and has a mouth portion, a shoulder portion, a barrel portion and a bottom portion, said bottom portion without being substantially affected by the residual strain due to orientation by fluidization.

Abstract: A container is made in two stages from thermoplastics material. In the first stage a preform (1) is injection molded, the mold parts easily releasing a tubular body (2) with a closed end and an outwardly projecting rim (3) at the open end. In the second stage the still heated preform (1) is blow molded, possibly with some preliminary mechanical stretching, with the blow pin (13) seated in the open end of the body (2) and the preform (1) held by the outer part (7) of its rim. The wall of the body (2) is expanded, and immediately be low the open end it is stretched outwardly to meld with the underside of the inner part (5) of the rim. The resultant container thus has a mouth defined by an inset lip. It may be of paint tin form, with a drip groove (9) around the mouth.

Abstract: A container is made in two stages from material such as thermoplastics that is deformable when heated. In the first stage a preform (1) is injection moulded, the mould parts easily releasing a tubular body (2) with a closed end and an outwardly projecting rim (3) at the open end. On or in the surface of the rim facing away from the body there is a formation such as a spiral rib (5) or groove. In the second stage the still heated preform (1) is blow moulded, possibly with some preliminary mechanical stretching, with the blow pin (9) seated in the open end of the body (2) and the preform held by the outer part (7) of its rim. The wall of the body (2) is expanded and the inner part (4) of the rim is urged away from the blow pin (9), deforming into a short tubular mouth with the formation (5) facing inwards. A spiral becomes a screw thread for receiving a screw-in cover.

Abstract: A container includes a body defining a chamber and a neck region. A straw is disposed within the chamber. The straw is inserted through the neck region and into the chamber prior to filling the chamber and is trapped or wedged between a first portion of the container and a second portion of the container by mechanical engagement with the container. The position of the straw within the chamber does not interfere with the filling of the container. When filling has been completed, the body of the container is manipulated to release the straw from its mechanical engagement with the container and position it within the neck region.

Abstract: The present invention improves performance of a flask used for microorganism, cell and tissue culture. The flask is composed of culture chamber, a wide oblong opening and a closure unit. The wide oblong opening eliminates the bottle neck restriction of conventional flasks and gives easy access to the culture chamber. The closure unit is constructed with a snap-on closure, a base and springs, which interconnect the closure and the main body of flask through the base. The springs function to maintain the closure at the opening position to facilitate culture operation. The problem of the screw-on closure that requires to be hold in a operator's hand is solved.

Abstract: The disclosed sports bottle has a liquid-tight body with a top wall defining a fill opening that can be closed by a removable cap. The fill opening is angled between 20 and 40 degrees relative to its circumferential wall, allowing nearly complete bottle filling with the bottle tilted, such as when filling from a drinking fountain with low water jet. A downwardly open hook formed off of the body near the its top, in close proximity with the longitudinal axis and laterally spaced from the fill opening, can suspend the bottle in a substantially upright leak-proof orientation, and within reach of an exerciser while on and possibly even using exercise equipment. A thermal chiller pack fits into the bottle interior via a bottom wall opening, being removably sealed as a unit in the bottle. The chiller pack has a solution sealed therein that can be cooled to freezer temperatures without solidifying or leaking from the pack, suited to be sealed to the bottle to keep the bottle liquid chilled for an extended duration.

Abstract: A closure unit for a container for storing and handling flowable products is made from at least two different thermoplastic materials, the different materials fulfilling different functions. A basic thermoplastic material (A.2) is used for sealing against the container (G.2), and an area made of another different thermoplastic material (B.2,C) is provided to fulfill additional sealing functions, to increase mechanical stability, to have a reduced permeability, and to provide increased elasticity for additional opening and closing and/or absorption characteristics. The closure unit is produced by a multimaterial injection molding process, so that contact surfaces between the different thermoplastic materials can be interconnected by reversible or irreversible positive engagement and/or by more or less pronounced melting into one another. The closure unit is in two parts and comprises a pouring part (1.2) and a closure part (2.2), or is in one part.
