Abstract: A simple car shielding cover, made of plastic film, being folded in a rectangular configuration, including a covering surface at the top to cover the top of car body, a rectangular opening at the bottom for insertion therethrough of car body, two closed ends having respective seaming lines, and two lateral inward folding surfaces to respectively cover the lateral sides of car body. The two lateral inward folding surfaces are outwardly disposed and define an inner space therebetween for receiving the car body. Two angular grooves are respectively defined by way of the covering surface and the inward folding surface around the seaming line. When the two angular grooves are respectively attached to the two bilateral ends of a safety bumper, the shielding cover is firmly secured to the bumper by way of the tensile force of the inward folding surfaces.

Abstract: A bottle cap which comprises an edge, a crown, a convex top on the crown, a cone at the interior center of the convex top, and a projection on the edge. The bottle cap is constructed in such way that after the cap is put on the mouth of the bottle, there is a clearance between the apex of the projection and an aluminum foil covering the mouth of the bottle. When the convex top is depressed with the thumb, the cone is lowered to pierce the aluminum foil, while the cap is opened by pushing the projection with the index finger. The bottle cap eliminates the need to pierce aluminum foil with a finger or other object. Accordingly, the liquids in the bottle will not be contaminated by the finger or other object before drinking. This meets economical, sanitary and easy-to-open requirements.
