The inner case is provided with an opening at the front side thereof and a protruded peripheral flange is disposed around the front opening, and a snap member perpendicular to the peripheral flange is disposed all therearound. The outer case is provided with an opening at the front side and a through hole at the rear side thereof with a peripheral edge defined on the rear side; the through hole is defined in such a size that the rear end of the inner case can be just fixed therein. On each inner side wall of the outer case is disposed a plurality of axially located protrusion ribs each of which is provided with a snap recess at the end adjacent to the front opening of the outer case so that the peripheral snap member can be firmly engaged with the plurality of protrusion ribs by way of the snap recess, or the snap member can be fixedly engaged with the protrusion ribs by way of adhesive glue or high frequency adhesion method, permitting the present plastic case to be structured in a simple and cheap manner and to be assembled in a fast manner and be reused as many times as its condition permits.</p> |
