ABSTRACT:
TECHNICAL FIELD
The present invention relates to a case for storing spare leads, in which a lead expelling portion with a spare lead passage formed therein, disposed at an opening portion of a body is caused to project, when in use, from an upper surface of the body, so that leads can be supplied directly into a lead tank of a mechanical pencil.
BACKGROUND OF THE INVENTION
As a spare lead storage case of this type, there have heretofore been known those which are disclosed in Japanese Utility Model Unexamined Publication (Kokai) No. Sho 58-163290 (1983) and Japanese Utility Model Examined Publication (Kokoku) No. Hei 2-313 (1990).
In the invention disclosed in the Japanese Utility Model Unexamined Publication No. Sho 58-163290 (1983), there is disclosed a spare lead storage case including a body, a partition portion formed on either the body or a closure member attached to the body, an outlet port formed in the partition portion all the way therethrough, a fixing hole formed in either the body (or the closure member) or a flip member and a locking pin formed on the rest (the body or the flip member). The locking pin is rotatably inserted into the fixing hole such that an expelling port formed in the flip member longitudinally all the way therethrough and the outlet port formed in the partition portion are coincident with each other when the flip member is in its protruded state.
The utility model of the Japanese Utility Model Examined Publication No. Hei 2-313 (1990) discloses a spare lead storage case, in which a lid member having an external configuration readily inserted into a lead tank of a mechanical pencil and provided with a spare lead passage formed therein is turnably attached to an upper opening portion of a spare lead chamber in a body such that the spare lead passage and a spare lead storage chamber are linearly communicated with each other when the lid member is in an open position, a side wall of the opening portion, with which a basal portion of the lid member is abutted when the lid member is turned, is formed as a resilient wall and a maximum enlarged diameter portion of an outer periphery of the basal portion of the lid member urges the resilient wall so as to be displaced during the turning operation of the lid member, thereby opening and closing the lid member.
Any of the above conventional spare lead storage cases has such advantages that the lead expelling portion with the spare lead passage formed therein disposed at the opening portion of the body can be projected from the upper surface of the body in use and the lead stored in the body can be supplied directly into the lead tank of the mechanical pencil through the lead expelling portion.
However, there are such inconveniences involved in the above conventional devices that in order to project the lead expelling portion with the spare lead passage formed therein from the upper surface of the body in use, it is required to project the lead expelling portion by holding an end face thereof and therefore, lead powder deposited on the end face of the lead expelling portion is readily adhered to the user's hand to soil it and in addition, the operation is troublesome.
SUMMARY OF THE INVENTION
It is, therefore, an object of the present invention to provide a spare lead storage case, in which the user's hand is not soiled when a lead expelling portion with a spare lead passage formed therein is projected from the upper surface of a body in use and in addition, the operation is simple.
A first aspect of the present invention provides a spare lead storage case comprising a body having a top plate portion in an upper portion thereof and a lid portion attached to the boy, the lid portion including a lead expelling portion having a spare lead passage formed therein and a link mechanism having a control portion, the lead expelling portion and the link mechanism being disposed in a space above the top plate portion, the lead expelling portion being connected to a side wall of the body through a movable portion, the link mechanism being connected to the lead expelling portion through a movable portion, the lead expelling portion being brought into an upstanding state by moving the control portion, thereby allowing the spare lead passage of the lead expelling portion to communicate with an interior of the body.
A second aspect of the invention is to provide a space lead storage case comprising a body and a lid member disposed in and attached to an upper portion of the body, the lid member including a lead expelling portion having a spare lead passage, a link mechanism, a control portion and a lid portion, the link mechanism having two movable portions, one of the movable portions being connected to the lead expelling portion, a partition wall being formed on either the lead expelling portion or the body, the lid portion being opened and the lead expelling portion being raised upward by movement of the control portion so that at least a distal end portion of the lead expelling portion is allowed to project from an upper surface of the body.
In a third aspect of the invention, there is provided a spare lead storage case comprising a body and a lid member disposed in and attached to an upper portion of the body, the lid member including a top plate portion having a spare lead passing hole formed therein, a lead expelling portion having a spare lead passage formed therein and a link mechanism having a control portion, the lead expelling portion being connected to the top plate portion through a movable portion, the link mechanism being connected to the lead expelling portion through a movable portion, the lead expelling portion being brought into an upstanding state by turning the control portion, thereby allowing the spare lead passage of the lead expelling portion to communicate with the spare lead passing hole of the top plate portion.
