Abstract: A bottle made of plastic material having a body extending along a central axis which comprises: a lower portion having a cross section with an essentially constant profile, followed by a gripping portion, and ending in an upper portion having a section with an essentially constant profile arranged in alignment with the profile of the section of the lower portion. The gripping portion comprises two globally plane gripping panels arranged parallel to one another and in relation to the central axis at a distance which is adapted for a hand taking. These panels have at least one reinforcing relief which extends in a transverse plane and are interconnected by connecting panels extending in continuation of the lower and upper portions by means of rounded corners located at the circumferential ends of the panels.

Abstract: A container bottom for minimizing deformnation. An outer rounded portion, an inner recessed portion, being generally ellipse shaped, and an offset portion extending along the inner recessed portion are adapted to minimize bulging caused by increased ambient temperature and pressure gradients to provide an improved container to store non-liquid goods.

Abstract: A coextrusion die includes a plurality of annular cells stacked on top of each other. Each annular cell includes a plurality of openings aligned with openings in the adjacent cell, thus forming multiple streams. Plastic melt may be supplied to the die coplanarly. Stacks of annular disks may be joined to form the annular cells through which plastic melt can be axially directed.

Abstract: A cylindrical vial having a bottom, for a medicine, in which an open end of the cylindrical vial is sealed by a needle-penetrable rubber closure through which a needle can be penetrated, the cylindrical vial including a conical bottom end provided opposite to the open end, wherein the apex of the conical bottom end is located on a central axis of the cylindrical vial at the bottommost point inside the cylindrical vial.

Abstract: A method of preventing curved-side containers on a conveyor belt of a commercial filling line from slipping across and past the curved surface of the forward container by providing a small flat area on opposing sides of the containers and positioning the containers in the filling line to cause the flat areas on one container to register with the flat areas on adjacent containers in the line, and a product container having curved sides with wider shoulders tapering to a narrower base, with a small flat area on each side of the container at the widest point on the container shoulders.

Abstract: A plastic bottle comprises a base having a chime, a dome and an annular wall extending between the chime and the dome. The annular wall extends generally parallel to a longitudinal axis of the bottle to support the dome against inverting due to internal pressure and increases the bi-axial stretching of the base during blow molding to strengthen the material of the same.

Abstract: There is provided a container having a container with open end, and a bottom cap has a sealant material bonded thereto to provide a hermetic seal between the bottom cap and the open bottom of the container and a grip surface through or slightly beyond the exterior surface of the bottom cap to contact a substrate, such as a table.

Abstract: A colored refracting cup includes a cup body, a recess chamber formed in a bottom of the cup body, the recess chamber having multi-angle cut faces, and a bottom cap fused with the bottom of the cup body by means of supersonic welding process. An adornment with multi-angle cut faces for refraction is fixed on the bottom cap and plated with many colors. The colors of the adornment may be refracted through the multi-angle cut faces of the recess chamber to appear on the cup body, permitting the cup body look like very brilliant and glamorous and enhancing worth of the cup.

Abstract: This relates to a returnable/refillable container in the form of a blow molded polyester biaxially oriented bottle wherein the container includes a domed base construction wherein the wall thickness gradually and smoothly increases to a maximum at the center of the dome. This also relates to a specially configurated preform which is blow molded to form the container and a specially configurated blow mold cavity for receiving a preform having a lower axial projection in the fore of an elongated gate without crushing.

Abstract: A container with improved crease-crack resistance and a method of making that type of container. The container utilizes a layer of a soft plastic on its exterior to control cracking at outward creases. When the container holds motor oil, the oil itself may plasticize the stiff material on the container's interior to preclude inward crease cracking. In this case, the stiff layer should have a sufficient thickness that an adequate amount of material remains unaffected by the oil and does not lose its rigidity or jeopardize the container's structural integrity. Where the contents do not provide the requisite improvement in inward crease cracking or would completely soften the stiff layer, then the container has a separate, soft, third layer of plastic on the interior of the container. The softness of this layer protects against inward crease cracking. It may also protect the stiff layer from softening by the bottle's contents.

Abstract: A blow molded container of the present invention is a container formed by blow molding in which a single-layer or multi-layer parison comprising a cylindrical resin material is heated and inflated by air in a mold, wherein a bottom sealing portion formed by pinch offs of the mold has a projection projecting outwardly from the container and sunk portions formed in one of the resin layers constituting the projection such a manner as to be buried in the other resin layer.

Abstract: A resin container has a bottom structure which has a central recessed portion containing substantially no crystal, a marginal raised portion crystallized by molecular orientation, and an intermediate ring-shaped portion crystallized to have spherulite-like crystals.The bottom structure highly improves the heat-resistance at the intermediate portion, while maintaining the central recessed portion at a good impact-resistance.

Abstract: A method for storing nanoparticulate suspensions of photographically useful compounds is disclosed that comprises the steps of:providing a suspension of nanoparticulate photographically useful chemical substance in the form of a solid particle dispersion;providing a hydrodynamically optimized container for storing nanoparticulate suspensions comprising a base portion and a body portion unitary with said base portion, said portions defining an interior storage chamber hydrodynamically optimized for the resuspension of sedimented nanoparticulate suspensions, said body portion further comprising a body wall with interior and exterior surfaces;placing said solid particle dispersion in said container;sealing said container and storage chamber against the ambient atmosphere to form a sealed container;storing said sealed container;opening said sealed container; andusing a portion of said solid particle dispersion stored in said container to form a coating composition for a light-sensitive element.

Abstract: The present invention is directed to a blow molded article and an apparatus and method for blow molding the article. The article contemplated by the present invention includes a recessed lip. The apparatus includes two plates reciprocally movable toward and away from one another. A center ring member and a separating ring are fixedly and perpendicularly mounted on each plate. A mold half is mounted on each plate and is divided into two sections. One section is located on each side of the center ring member and is reciprocally movable toward and away from the center ring member. A first insert member is provided in each mold section in proximity to said center insert member. The first insert has a channel therein for receiving a second insert member. The second insert member is reciprocally movable in said channel and engages the center ring member.

Abstract: A container constituted of injection-molded plastic components, the components having the property of enabling discrete particles thereof to be securely joined to each other under the action of heat and pressure. The injection-molded components form a pair of continuous mating edges adapted to constitute a common continuous joint in the container. The edges initially have configurations enabling them to be mutually abutted, and the edges after being so abutted having been subjected to heat and pressure of a magnitude sufficient to cause them to meet and merge into each other to form the continuous joint.
