摘要： Disclosed is a seaming cap coupled with a reinforcement plate of a spin-on filter. The seaming cap (41) includes: a central hole (41a) formed in an annular shape; a securing groove (41b) formed in an annular shape by folding the lower end of the outer periphery of the central hole (41a), with an annular packing member (42) inserted therein; a seaming coupling section (41c) protruded and folded downwards at the outer periphery of the securing groove (41b) for seam-coupling to an outer peripheral surface at the upper end of a spin-on filter housing (10); and a plurality of injection-molding object extrusion holes (41d) formed in the securing groove (41b) of the seaming cap (41) at the same intervals. An extrusion object (40e) of the reinforcement plate (40) is extruded into the securing groove (41b) to which an annular packing member (42) of the seaming cap (41) is secured, when injection-molding the reinforcement plate (40) via the injection-molding object extrusion holes (41d). According to the present invention of the above structure, the reinforcement plate is injection-molded from the plastic material and coupled with the seaming cap, so that the extrusion object is formed in the annular shape on the bottom surface in the securing groove of the seaming cap, thereby being stably coupled with the seaming cap. In addition, the seaming cap is positioned between the upper mold and the lower mold of the injection molds and the threads of a spiral hole of the reinforcement plate are formed simultaneously with the injection of the reinforcement plate, so that the coupling time between the reinforcement plate and the seaming cap is reduced, thereby increasing productivity. The reinforcement plate is produced by insert injection molding with the seaming cap, which is inserted into an injection molding machine, so as to reduce weight. The plastic injection molded object and the seaming cap may be easily separated when discarding the spin-on filter. It is possible to reuse the plastic material and employ the same as an energy source.

摘要： The present invention relates to a filter element using a plastic cap integrated with a relief valve, wherein a net type core 21 is received in a spin-on filter housing 10 in the cylindrical shape opened at the top portion thereof and formed with a plurality of oil passing holes 21a in the periphery thereof, and an oil pleated paper 22 is positioned to maintain the shape thereof at the periphery of the core 21 so as to be positioned at a small distance from the inner wall of the housing 10. The filter element 20 includes: an upper cap 23 formed of a plastic material at the upper end thereof; and a fixed lower cap 50 integrated with a relief valve formed of plastic material at the lower end thereof. The fixed lower cap 50 integrated with a relief valve receives and fixes a relief valve 30, which is formed of a valve plate 32 and an elastic spring 33. In the filter element 20, the core 21 is covered by the upper cap 23 and the lower cap 50, which are kept in close contact with the outside of the core 21. According to the present invention, assembly of the valve plate 32 and the elastic spring 33 of the relief valve 30 is simplified by integrating a plurality of upper holding protrusions 52 of the fixed lower cap 50 integrated with a relief valve. In addition, the deviation of an element compression spring 25 closely contacting the lower inner surface of the housing 10 by the oil which is introduced into an oil hole 53 is prevented by the integration of the lower holding protrusions 52. Furthermore, the upper cap 23, the fixed lower cap 50 integrated with a relief valve and the core 21 are manufactured by plastic injection molds so as to reduce weight. The spin-on filter may be reused without separation from the oil pleated paper 22, which is fixed by a thermosetting resin 22a (since both are formed of the same materials) when discarding the spin-on filter. In addition, it is possible to use the element in the generation of renewable energy.
