が強く要望されている。``Conventional technology'' Making large containers like drums from resin is lightweight, durable, and
It is extremely effective in improving rust prevention, and various synthetic resin drums have already been developed and used in Europe and America. In Japan, closed metal drums are currently widely used, but studies are rapidly progressing to replace them with synthetic resin. In this case, it is strongly desired to provide a gripping part with an outer diameter approximately equal to the outer diameter of the body part near the periphery of the top plate so that the existing steel drum handling jig can be used as is.

対応させることが困難である。“Problems to be Solved by the Invention” However, the synthetic resin drum manufactured to meet the above requirements has a gripping portion formed on the top plate, and a spout provided on the top plate that is close to the gripping portion. In addition, there is a difference in the distance that the molten parison extends (blow ratio) in the parting direction and in the direction perpendicular to the parting, and build-up and notches occur on the inner surface of the drum at the gripping part, causing impact. Reduce strength. Furthermore, if the spout is formed during blow molding, the threads formed during blow molding have poor accuracy, and in order to increase the tightening torque, it is necessary to increase the depth and pitch of the thread, so it is not commonly used. It is difficult to make it compatible with the existing cap.
また、特殊な細かいねじの場合、オレフィン系重合体の
みでは剛性が不足して規格に合った締付トルクを出すこ
とが出来ない等の問題があった。In addition, in the case of special fine screws, there are problems such as insufficient rigidity with olefin polymer alone and the inability to produce tightening torque that meets standards.

。"Means for Solving the Problems" The present invention has been made to achieve the above object, and its gist is that the body, the top plate, the base plate, the top plate, the base plate, and the vicinity of the outer periphery thereof. In a drum in which an annular gripping part that is attached concentrically and whose diameter expands outward is integrally molded by blow molding using an olefin polymer, the outer diameter of the tip of the gripping part that is attached to the top plate is as above. The outer diameter of the body is approximately equal to the outer diameter of the body, and the spout provided on the top plate is made of an injection molded product made of the above-mentioned olefin polymer or a composition in which an inorganic filler is added to the olefin polymer. It is a synthetic resin drum that is welded and formed.

Ethylene monopolymer of 935 g/cm3 or more, or ethylene and α-olefin whose main component is ethylene (usually 3 to 12 carbon atoms, copolymerization ratio of α-olefin is 15 wt%)
It is a copolymer of the following). The molecular weight of these ethylene monopolymers or copolymers of ethylene and α-olefin varies depending on the size and capacity of the drum to be manufactured, but the melt flow rate (according to JIS K 6760 at a temperature of 190°C and a load of 21.0°C) is determined by the following. For example, in the case of a 200 drum (measured under the condition of 6 kg, hereinafter referred to as rHLMFRJ), a drum of 5.0 g/10 min or less can be used, but one of 13.0 g/10 min or less is particularly preferred.

を有する。"Effects" As described above, the synthetic resin drum of the present invention is made by blow-molding an ethylene polymer and has no plug, and the ethylene polymer or this and an inorganic filler are added to the drum. The spout is separately molded by kneading and injection molding, and is attached by welding.The outer diameter of the upper part of the top plate gripping part is equal to the outer diameter of the body, and during blow molding, the part The difference between the blow ratio in the parting direction and the direction perpendicular to the parting is reduced, the wall thickness is equalized, it is lightweight, non-corrosive and hygienic, and can be transported with the conventional handling jig used for interlayer drums. In addition, the spout has many advantages, such as a wide range of adaptations, since the spout can be fitted with a cap of a desired size and can be mounted at a desired position.
