Description

  The present invention relates to a stationery, and more specifically, to a writing instrument that easily separates a pen cap and a barrel (pen shaft).

  Commercially available markers, highlighter pens and the like generally include a barrel and a cap, the pen replacement core is placed in the pen barrel, the brush tip is exposed at the writing end of the barrel, and writing on the barrel is performed. The barrel end of the end is sealed with a cap. When the refill ink runs out, the refill is sealed to the barrel with a cap, so even if the barrel is not damaged, users often have to throw out the pen without changing the refill ink. There is a lot of economic problems.

  SUMMARY OF THE INVENTION In order to solve the drawbacks of the prior art, the present invention is to provide a writing instrument that has a simple structure and that allows a pen cap and a barrel to be easily attached and detached.

In order to achieve the above-mentioned object, the present invention comprises the following techniques:
The present invention includes a pen barrel, a pen cap, and a pen sheath (cladding tube). The barrel includes a writing end and a distal end disposed opposite to the writing end, and the cap includes an inner end. And an outer end portion disposed opposite to the inner end portion, the sheath includes a first end portion and a second end portion disposed opposite to each other, and an inner end portion of the cap includes the barrel The writing end of the barrel is movably connected to the first end of the sheath. The feature is that the outer end portion of the cap (2) and the second end portion of the sheath (3) have a first fitting member and a second fitting that can be fitted to each other in size and shape. A female screw part and a male screw part are provided on the outer side of the inner end part of the cap and the inner side of the end part of the barrel.

  According to one embodiment, the first fitting member is a protrusion of the cap provided at the outer end of the cap, and the protrusion of the cap is provided with a concave groove of the cap. In the fitting member, a second end portion provided on the sheath of the pen is a concave groove portion of the sheath that is fitted to the protrusion portion of the cap, and the concave groove portion of the sheath is a concave groove portion of the cap. Protruding portions of the sheath that can be fitted to each other are provided. The concave groove part of the cap is, for example, a letter-shaped concave part, and the projection part of the sheath is a corresponding letter-shaped projection part. The concave groove portion of the cap and the protruding portion of the sheath may be a concave groove portion and a protruding portion having other shapes, and may be, for example, a cross shape, a hexagonal shape, a star shape, or any other shape.

  According to another embodiment, the pen sheath can be a one-shaped protrusion, and the sheath is provided with a pressing member, and the position of the pressing portion is the protrusion of the sheath. The angle of the vertical axis is 45 degrees with respect to the vertical axis, so that when the protrusion of the sheath fits into the groove of the cap, the cap can be easily twisted open. .

When the user needs to attach and detach the pen cap and pen barrel, the outer end of the pen cap is interlinked with the first and second mating members at the second end of the pen sheath. Then, the screw can be twisted open using the screw, and the pen cap is twisted open with the pen sheath.

1 is a front view according to an embodiment of the present invention. It is a top view by embodiment of this invention, and is a figure which shows the outer end part of a cap. It is a three-dimensional view according to an embodiment of the present invention. The outer end part of the cap by embodiment of this invention is a figure which shows the state which the 1st fitting member and 2nd fitting member of the 2nd end part of a sheath have fitted mutually. It is a figure which shows the state when the cap by this embodiment of the invention, the barrel, and the sheath are mutually attached or detached.

  Hereinafter, the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. As shown in the drawings, in this embodiment, a pen barrel (1), a pen cap (2), and a pen sheath (3) are provided. The barrel (1) has a writing end (11) and the writing end. The cap (2) has an end portion (12) disposed opposite to the end (11), and the cap (2) is disposed on the inner end portion (not shown) and the outer end portion (facing the inner end portion). 23), the sheath (3) has a first end (31) and a second end (32) arranged to face each other, and the inner end of the cap (2) 1) inserted into the distal end (12), the writing end (11) of the barrel (1) is movably connected to the first end (31) of the sheath (3). On the outside of the inner end portion (21) of the cap (2) and on the inner side of the end portion (12) of the barrel (1), there are provided a female screw portion and a male screw portion that can be screwed to each other [drawings. Only the external thread part (22) provided outside the inner end part (21) of the cap (2)], the outer end part (23) of the cap (2), and the sheath (3) first Each of the two end portions (32) has a first fitting member and a second fitting member that can be fitted to each other in size and shape. In the present embodiment, the first fitting member is a cap projection (24) provided at the outer end of the cap (2), and the cap projection (24) is a concave groove (25) of the cap. ), And the second fitting member includes a concave groove portion of the sheath in which a second end (32) provided on the sheath (3) of the pen is fitted to the protrusion (24) of the cap. 33), and the concave groove portion (33) of the sheath has a protruding portion (34) of the sheath that can be fitted to the concave groove portion (25) of the cap. In the present embodiment, the concave groove portion (25) of the cap is a single-shaped concave portion, and the protruding portion (34) of the sheath is a corresponding single-shaped protruding portion. In other embodiments, the cap groove and the sheath protrusion can be other shapes of groove and protrusion, for example, cross-shaped, hexagonal, star-shaped or any other shape. You can also.

  In the present embodiment, the pen sheath has a pressing member (35), and the position of the pressing portion is a position shifted from the vertical axis of the projection (34) of the sheath by an angle of 45 degrees. Thus, when the protrusion (34) of the sheath is fitted into the concave groove (25) of the cap, the cap can be easily twisted and opened.

  When the user needs to detach the pen cap (2) and pen barrel (1), the outer end (23) of the pen cap (2) is connected to the second end (32) of the pen sheath (3). The first fitting member and the second fitting member are engaged with each other, and the pen cap is twisted open with the pen sheath so that the screw is twisted open using the screw.

  The above-described embodiment is a preferred embodiment of the present invention. However, the present invention is not limited to the above-described embodiment, and in other words, the present invention can be used without departing from the spirit of the present invention.
