Abstract:
A container adapted for use by an infant or a child is provided. The container has handles with first and second side walls that diverge away from each other, in the direction away from the outer circumference of the body of the container toward the center line of the container. The container can also have a base with at least one base recess formed therein and an inwardly tapered bottom surface, providing improved strength.
Abstract:
A fuel tank for a motor vehicle comprising a wall composed of two shells arranged one above the other. The outer shell of the wall preferably has an inlet orifice and an outlet orifice. A filter element is arranged in front of the outlet orifice. Scavenging air from the inlet orifice thereby passes first into a gap between the shells and subsequently to a filter element. As a result, fuel vapors can no longer diffuse through the wall and pollute the environment.
Abstract:
A bottle having substantially no strain due to fluidized orientation in the bottom portion thereof which is homogeneously and uniformly drawn, and, as a result, exhibiting improved shock resistance and buckling strength in the bottom portion, featuring excellent resistance against environmental cracking at the center in the bottom portion, without developing crazing or whitening during the preservation, and offering excellent appearance. 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 has a body which comprises front and rear walls, and the side walls. Each of the front and rear walls has an elliptic cross section, and is provided with a lateral recess. Each of the side walls is a vertical plane which intersects the elliptic cross section of the front and rear walls, and is provided with a plurality of reinforcements. The container has a bottom which comprises a peripheral wall connected to the body and a bottom wall. The peripheral wall comprises slightly inclined front and rear walls, and side walls inclined by a predetermined angle. The peripheral wall is provided with a reinforcing rib.
Abstract:
An object of the present invention is to improve shock resistance of nursing bottles formed of a PES resin so as to provide them with such a sufficient falling impact strength that they can be used pleasantly and safely. The injection-blow-molded PES nursing bottle of the present invention has a gate flash (6) at a central portion of a bottom (5), the flash being generated when the resin is previously injected to prepare a parison. The central bottom portion (5) is raised to be of a convex shape to bulge up towards a mouth of the bottle. A height ‘h’ of such a raised bottom portion is from 9% to 20% of an inner diameter ‘R’ that is possessed by a floor-engaging rim of the bottom, the rim being generally circular in a bottom plan view.
Abstract:
A PET bottle having structurally improved vacuum absorption panels in the bottle portion so as to increase the panels' resistance to the constricting force of the shrink label, to secure the force of restitution for the panels, and thereby to allow the liquid level in the bottle to lower when the cap is opened. Vacuum absorption panels comprising multiple, flat and variable surfaces, recessed from the plane of each corresponding main body wall; multiple, horizontal and grooved ribs, and having respectively a curved bottom with the middle portion of this bottom being slightly uplifted, and with each rib being placed under a variable surface in an alternately disposed manner.
Abstract:
Disclosed herein is a fuel tank of multi-layer construction having good impact resistance as well as good barrier properties for gasoline, especially one containing methanol and MTBE. The fuel tank comprises (a) inner and outer layers of high-density polyethylene, (b) intermediate layers of adhesive resin, and (c) a core layer of ethylene-vinylalcohol copolymer, with said core layer (c) being shifted to the inside. For better performance, the layer (c) has a thickness which satisfies the formula below. 0.005≦A/B≦0.13 (1) where A is the thickness of the layer (c), and B is the thickness of all the layers. The fuel tank is suitable especially for oxygen-containing gasoline.
Abstract:
A blow-molded plastic bottle body for use in containing hot-filled beverages. The bottle body has a dome with various interactive functional zones. For example, some of the zones are primarily responsible for accommodating vacuum absorption, while other zones are primarily intended to rigidify the container such as by providing column strength to improve container top loading capability. Although each zone may have a primary function, each zone also aids adjacent zones in providing their functions. Thus, the entire dome, and not merely selected locations, reacts in a progressive manner to the forces generated by the hot-fill process on the bottle body. Preferably, the bottle body is slender and capable of readily being gripped by a single hand, and preferably the flex panels in the dome accommodate at least 90% of the total vacuum absorption required by the bottle.
Abstract:
Hot-fillable, blow molded, wide-mouth plastic containers having a pair of flex panels (11, 111, 211) for accommodating thermally induced volumetric and pressure variations while affording easy contents scoopability, and desirable labeling features. The containers are capable of being blow-molded from injection molded preforms or from extruded parisons. The containers may be hot-filled and retorted. A desirable base (27, 127, 227) for a retortable container is also disclosed.
Abstract:
The invention relates to a blow molded fuel tank having a heat shield which is fixedly joined to the fuel container. The positive fit between the heat shield and fuel container is achieved by integrating by molding claw-like protrusions of the heat shield.
