Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an article with a cap, such as a ballpoint pen or the like.

"Prior Art" For example, a ballpoint pen is designed to transfer ink from an ink shaft onto paper or the like by rotating a ball at the tip. In such ballpoint pens, if the ball portion at the tip is damaged, the pen becomes unusable, so this portion is generally protected with a cap.

``The problem that the invention attempts to solve'' By the way, with conventional ballpoint pens like this,
Since the cap is removable from the ballpoint pen body, the cap that was removed for writing was often lost. In order to avoid this, the cap that is removed for writing is sometimes attached to the head of the ballpoint pen body, but even with this method, it has not been possible to completely eliminate the loss of the cap.

In addition, since such conventional ballpoint pens are designed only for writing purposes, there is little in the way of hobby or visual changes.

The present invention was developed in light of these circumstances, and is designed to be used as a pen, such as a ballpoint pen, that does not lose its cap, has a variety of hobbies and visual variations, and can respond to the diversification of tastes. The purpose is to provide products with caps.

``Means for Solving the Problems'' The cap article according to the present invention has pairs of rods having different lengths arranged alternately in a parallelogram link shape, and each end of the rods is a connecting body that can be bent and deformed. A component with a predetermined function is attached to the rod with a part protruding from one side of at least one of the connectors, and the component is attached to the other side of the connector. The four rods are provided with recesses for accommodating and protecting the protrusions thereof and are attached to the rods, and the mutually opposing inner surfaces of the four rods are appropriately provided with engaging protrusions and engaging holes, and are shaped like parallelograms. When the parallelogram link shape is broken into a straight state so that the rods having different lengths and the inner surfaces of the rods arranged in a link shape are brought into contact with each other, the protruding portion of the component is exposed and used. state, and the parallelogram link shape is broken in the opposite direction to the above-mentioned use state so that the inner surfaces of the rods and the rods of other combinations having different lengths of the four rods are brought into contact with each other, and the shape is changed to another straight state. Then, the protrusion of the component is accommodated in the recess and becomes unused, and this used or unused state is maintained by the engagement between the engaging protrusion and the engaging hole. It is characterized by the fact that

According to the present invention, when the part is, for example, an ink shaft of a ballpoint pen, the tip of the ink shaft is exposed when it is in use, so it can be used like a normal ballpoint pen.
On the other hand, when the ink shaft is not in use, the tip of the ink shaft is housed in the recess and is protected, so the recess can be used as a cap and there is no chance of the recess being lost. Can be done. Furthermore, since the parallelogram link-shaped rod is opened once when changing from an unused state to a used state, for example, it is possible to enrich the hobby or visual changes.

Furthermore, if two of the four rods in a given set and the connecting bodies on both sides of the rods are integrally formed from synthetic resin, the number of parts and assembly man-hours can be reduced. will be possible.
