BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a cap for writing instruments such as a mechanical pencil, a ball-point pen, and the like, and particularly to a cap for writing instruments to which a safety measure is applied so that even if a curious infant should inadvertently swallow a cap, which as a result becomes lodged in his (or her) throat, ventilation of air is secured.
2. Description of Background Information
The cap for writing instruments to which a safety measure is provided has been hitherto known in the technical field concerned. In general, a cap is designed for the purpose of protecting the writing instrument from a physical damage or for the purpose of improving a design (such as an ornamentation), the cap being detachably mounted on an extreme end (a pen-point) or a rear end of writing instruments. For example, in a case of a cap for a mechanical pencil, a so-called knock-cap, the cap is designed to protect an eraser mounted at a rear end of a tube in which a lead container (a refill) is provided, whereby when an eraser is used or when an eraser is removed and a mechanical lead is placed in the lead container, it can be removed in a simple operation, such as by pulling it off.
Caps for writing instruments to which a safety measure is provided as described above are disclosed, for example, in Japanese utility Model Laid-Open Nos. HEI 4-77489, 4-104485, 4-104486 Publications, and various ventilating constructions have been known.
Any of the conventional caps described above are safety caps which can provide passage of air by the presence of a ventilation construction such as a vent hole provided in the cap itself even if an infant or the like should inadvertently swallow the cap. However, as a result the external (contour) shape is impaired, and the design is adversely affected. For example, in the case of the caps disclosed in Japanese utility Model Laid-Open Nos. HEI 4-104485 and 4-104486 Publications, radially extending ribs are provided which extend outwardly from a tubular portion and toward a rear end of the cap from a centrally located shoulder of the cap and in an axial direction. A vent hole is provided in the end of the tubular member, and the cap has an external shape with a cylindrical body and spherical end shape peculiar to the cap. Accordingly, an object of the present invention is to prevent the degrading of a design or ornamentation for the article while providing a safety measure so that even if a curious infant should inadvertently swallow a cap, which as a result becomes lodged in his (or her) throat, passage of air is maintained.
Further, another object of the invention is to further improve a design of the goods in which a ventilating construction of the safety measure appears to form a pattern.
SUMMARY OF THE INVENTION
The present invention includes a closed-end tubular cap body and a body piece fitted in a mounting opening provided in a suitably shaped opening at a closed rear end thereof. The body piece has a shape sized and matched to the shape of the mounting opening of the cap body, and includes a plurality of parallel, air ventilating depressions communicating into the cap body. The depressions are provided in spaced relation along at least one side edge of the body piece and adjacent an opening edge of said mounting opening.
Accordingly, even if a person should inadvertently swallow a cap, which as a result becomes lodged in his (or her) throat, a plurality of air ventilating depressions communicating with the interior of a cap body are provided in the side edge of the body piece so that passage of air can be maintained. Namely, the ventilation construction to secure passage of air appears as a line pattern by an open edge of a cap body, and by open edges of a plurality of air ventilating depressions of a body piece juxtaposed in a given spaced relation and sized and matched to the edge of the opening.
Furthermore, the present invention includes a bridge piece for supporting a part of a curved projecting end of the body pie
