Container having a breakable pouring cap

摘要

A container having a breakable pouring cap (116) for pouring oil into an oil tank (114). The cap (112) is snapped onto a neck portion (116) through the engagement of an inner projection (146) on the open end of the cap (112) and an outward annular projection (122) on the neck portion (116) of the container. The cap is sealed by means of a pair of annular radial projections (122 and 124) on the outer surface of the neck portion (116) of the container, these projections having sliding fit with the inner surface of the cap (112). The end face of the neck portion (116) is skewed and forms a piercing tip (130) at its lowermost end and a cutting edge (128) on the remaining peripheral portion of the end face. In use, the container is inserted in an inverted position so that the breakable cap extends into an inlet opening (111), e.g., of the oil tank. Radial ribs (142) are wedged in the inlet opening by applying an axial force to the container body (110), and the body is then pushed down, whereby the piercing tip (130) pierces the bottom portion (134) of the cap; with the further downward movement of the container, the cutting edge (128) shears the bottom portion and thus opens the container, allowing the oil to flow into the motor oil tank (114). In another embodiment, the cap and the neck are provided with additional sealing means in the form of inner radial segments (302 and 304) on inner surface of the cap and outer projections (306 and 308) on the neck. When the cap is snapped onto the neck and then is twisted, the segments and projections form a tight fit.
