Abstract:
A plastic container includes a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a tamper-evident formation, threads, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. In an embodiment, the weight of the neck portion is 2.3 grams or less; a vertical distance from the lower surface of the tamper-evident formation to a top of the dispensing opening is 0.30 or less; and/or the container may be filled with a beverage. In embodiments, the volume of the container may be at least 500 ml. A preform and method for making a container are also disclosed.
Abstract:
A plastic preform is provided that includes a hollow body portion including a closed bottom portion and a lower portion extending upwardly from the lower portion; and a neck portion extending upwardly from the lower portion. The neck portion includes a dispensing opening; threads positioned below the dispensing opening; a tamper-evident formation positioned below the threads; and a support flange positioned below the tamper-evident formation, the support flange having an upper surface and lower surface. In an embodiment, the preform is formed of a material comprising polyethylene terephthalate (PET); the threads comprise multiple-lead threads; the weight of the neck portion from the lower surface of the support flange to a top of the dispensing opening is 3.0 grams or less; and the vertical distance from the top of the dispensing opening to the lower surface of the support flange is 0.500 inches or less. A method is also disclosed.
Abstract:
This invention relates to the preform to produce a plastic container for packaging foodstuffs, and especially to blow mould thin-walled containers which can be hermetically closed with a metal lid by double seaming. The preform (1) includes a body (4) and a convex hemispherical bottom (6). The body (4) has a conical shape that flares towards a cylindrical neck (2) surrounded by a flange (3) that terminates in a thickened rim (5). Preferably, the angle (α) at which the internal body surface (4) flares towards the cylindrical neck is greater than the angle (β) at which the external body surface (4) opens upwards, and the thickness (g2) of the cylindrical neck (2) is less than the thickness (g3) of the bottom (6).
Abstract:
A plastic preform is provided that includes a closed bottom portion; a lower portion extending upwardly from the bottom portion; and a neck portion extending upwardly from the lower portion. The neck portion includes a support flange having an upper and lower surface, threads, a tamper-evident formation, and a dispensing opening at the top of the neck portion. In an embodiment, the weight of the neck portion is 3.0 grams or less; and the vertical distance from the top of the dispensing opening to the lower surface of the support flange, including the threads and the tamper-evident formation, is 0.580 inches or less. A container and method for making a container are also disclosed.
Abstract:
The object of the present invention is to provide toner bottles and the like in which the possibility to damage the ring gear, in particular the teeth of the ring gear, is remarkably suppressed at processing the toner bottle such as handling, packaging, and transporting, thus packaging and transporting are principally possible without cushioning materials. Accordingly, provided is a toner bottle comprising a cylindrical bottle having a bottom, a cylindrical aperture for supplying a toner, and a ring gear, wherein a helical concave is formed on the side wall of the cylindrical bottle along the axis of the cylindrical bottle, the cylindrical aperture is disposed at one end of the cylindrical bottle, the cylindrical aperture is concentric with the cylindrical bottle, and the outside diameter of the cylindrical aperture is smaller than the outside diameter of the cylindrical bottle, the ring gear is disposed on the cylindrical aperture, the ring gear is concentric with the cylindrical aperture, and the tip circle diameter of the ring gear is smaller than the outside diameter of the cylindrical bottle.
Abstract:
A hollow, cylindrical toner bottle of the present invention discharges toner stored therein when mounted to an electrophotographic image forming apparatus in a substantially horizontal position and then rotated about its axis. The toner bottle is made up of a mouth including a toner outlet and a cylindrical wall, and a body including a circumferential wall and a bottom. The mouth is formed by injection molding. The outer circumference of the toner outlet has circularity of 0.7 mm or below.

Abstract:
Disclosed is a process for drawing plastic laminates, which comprises draw-forming a laminate comprising a layer of a polyester composed essentially of ethylene terephthalate units, a gas barrier layer of an olefinvinyl alcohol copolymer and an adhesive layer interposed therebetween under temperature and draw ratio conditions satisfying a requirement represented by the following formula: ##EQU1## wherein X stands for the area draw ratio (%) defined by the formula of X=100(tho/th-1) in which tho stands for the thickness of the laminate before draw forming and th stands for the thickness of the laminate after draw forming, Y stands for the vinyl alcohol content (mole %) in the olefinvinyl alcohol copolymer, and t stands for the draw forming temperature (.degree. C.).
