Abstract
A hinge cap includes a body and an upper lid connected to each other by a hinge. The body includes a top board and a side wall extending perpendicularly downward from a periphery of the top board. The top board includes a planned opening defined by a weakened portion and a discharge nozzle formed to surround the planned opening. The upper lid includes a top panel and a skirt extending perpendicularly downward from a periphery of the top panel. A protrusion extending in an axial direction of the cap is formed in the planned opening of the body on a side opposite to the hinge such that an end of the protrusion is fixed to an inner surface of the top panel of the upper lid in a closed state.
Claims8
A hinge cap comprising a body and an upper lid connected to each other by a hinge, wherein
- the body includes a top board and a side wall extending perpendicularly downward from a periphery of the top board, the top board including a planned opening defined by a weakened portion and a discharge nozzle formed to surround the planned opening,
- the upper lid includes a top panel and a skirt extending perpendicularly downward from a periphery of the top panel,
- a protrusion extending in an axial direction of the hinge cap is formed in the planned opening of the body on a side opposite to the hinge such that an end of the protrusion is fixed to an inner surface of the top panel of the upper lid in a closed state,
- the weakened portion is lower in the axial direction of the hinge cap on the side opposite to the hinge than on a hinge side,
- the top board of the body includes a first inclined surface that is inclined downward in the axial direction of the hinge cap from the hinge side to the side opposite to the hinge at an acute angle to a horizontal direction of the hinge cap, and the top board includes a second inclined surface that is inclined downward from a lower end of the discharge nozzle on the side opposite to the hinge to the planned opening, and
- the planned opening is formed on the first inclined surface of the top board.
