A handle for a container capable of providing the container formed in a square shape in cross section, having excellent storability and blow molding properties, preventing various defects from occurring in the container and the handle, and having sufficient strength against falling impact, the container with the handle, and a method of manufacturing the container. The container with the handle is characterized by comprising the polyester container formed of a mouth part, a shoulder part, a body part, and a bottom part in order from the upper part and the polyester handle fitted to a handle mounting projected part of the container. A recessed part is formed in a part of the body part, and the handle mounting projected part is formed on the recessed part. A space part is formed between the wall surface of the handle mounting projected part on the recessed part and the handle. The body part is formed in a square shape in cross section, the recessed part is positioned at the upper half corner part of the body part, and the handle mounting projected part is positioned at the recessed part on the upper half diagonal line L.

The plastic preform (1) comprises a heat sealable neck finish (2) having at least a first upper heat sealable portion (20) which is terminated by a top opened end (200), a second intermediate threaded portion (21) for screwing a closure cap, and a third lower portion (22) that comprises a neck support ring (221a) of width (L1). The first upper portion (20) comprises an annular gripping recess (201) of predetermined height (H2) and depth (d). The inner face of the third lower portion (22) forms an inward transition step (221 b), and the outer diameter (D3) of the preform measured just below the neck support ring (221a) is less than the outer diameter (D2) of the neck finish measured just above the said inward transition step (221b).

The present invention provides a method for manufacturing a heat-resistant handle-equipped container. The method comprises the steps of insert-molding a separate polyester handle onto a top part of a body part of a hollow container when the container is formed by blow-molding a polyester preform and blow-molding with a blow-molding mold positioned so that a central axis of the body part below a handle-attaching convexity provided to a concavity on a top half of the body part is inclined 1°±0.5° toward the handle-attaching convexity; and heat-setting a wall surface that surrounds the handle-attaching convexity in the concavity.

A construct for a hockey blade and a method for producing the same that includes a foam core (30). The foam core includes a first core face (32), a second core face (34), and a core edge (36,38). A first layer of resin preimpregnated tape (40) is wrapped continuously around the first core face (32), the core edge (36,38) and the second core face (34). A thread (70) is stitched along the first layer of preimpregnated tape (40). A second layer of resin preimpregnated tape (82) wrapped continuously around the first layer of resin preimpregnated tape.
摘要:
The present invention relates to a process for making a lower molecular weight polymer from a solid stated higher molecular weight feed stock chip. In particular, the molecular weight of an industrial resin or a bottle resin is reduced in a controlled manner by the introduction of ethylene glycol. If the industrial resin is to be employed for industrial fibers, the ethylene glycol may be added at the extruder for spinning the industrial fiber. On the other hand, should the high molecular weigh chip be used for bottle resin, the molecular weight may be reduced by the introduction of ethylene glycol at the extruder for injection molding of preforms of a lower molecular weight. The ethylene glycol/polymer ratio is determined by the reduction in molecular weight that is required. The preferred resin is polyester polymer or copolymer, and especially polyethylene terephthalate (PET). The present invention comprises a process for reducing the molecular weight of a solid stated polyester feed stock resin comprising obtaining polyester resin having an IV greater than about 0.8 dl/g; and mixing ethylene glycol with said polyester wherein said ethylene glycol is present in a stoichiometric amount to reduce the IV to the required level.
