Specifically, it is a writing instrument cap in which an inner cap is engaged with the main body of the cap, and by specifying the structure and combination of both of the above-mentioned members, the writing instrument satisfies the assembly workability, the fitting strength of the inner cap, etc. It provides a storage cap for use.

従来、この種のキヤツプでは、内キヤツプの固
定は単に圧入によるもの、或いは別部材の介在に
よるもの等が主であり、内キヤツプの脱落や加工
性の面で必ずしも満足できるものではなかつた。 Conventionally, in this type of cap, the inner cap has mainly been fixed simply by press-fitting or by intervening another member, which has not always been satisfactory in terms of the inner cap falling off and workability.

殊に大径の筆記具用のキヤツプにおいて、キヤ
ツプ主体が軟質のプラスチツクで形成されたもの
では、応力による変形による固定強度の低下を免
れず有効な簡便な対策が望まれていた。 Particularly in caps for large-diameter writing instruments, where the main body of the cap is made of soft plastic, a simple and effective countermeasure has been desired to avoid a reduction in fixing strength due to deformation due to stress.

本考案キヤツプは前記した従来の不具合を解決

ができる。 The main body 2 of the cap has at least two legs 2-1 vertically disposed on the top surface of the cap, excluding the central part thereof, parallel to the side wall, and a small protrusion 2-1 is provided on the inner surface of each leg 2-1. The inner cap 3 has a base 3-1 and at least two axial ribs 3-2 corresponding to the leg pieces 2-1 on the outer wall of the base 3-1. It is integrally formed with the cylindrical part 3-3 leaving an axial recessed gap 3-4 in which the piece 2-1 is inserted, and a protrusion 3-5 is formed on the outer peripheral surface of the cylindrical part 3-3. Both members can be obtained by injection molding of plastic. The protrusions 3-5 in the above need only have locking strength, and are not limited to the annular shape shown in the illustration, but may be arranged at appropriate intervals. Further, although the drawing shows an example of a combination of two leg pieces 2-1 and two corresponding ribs 3-2, the number of leg pieces 2-1 is in the range of 2 or more and about 8 or less. Moreover, it is sufficient that at least two ribs 3-2 are provided corresponding to the leg pieces 2-1, and the number of ribs 3-2 is not necessarily the same as the number of leg pieces 2-1. Note that a clip (not shown) can be integrally provided on the outer surface of the cap main body 2 as required.

成される。 Inside the cap main body 2, the inner cap 3 connects the protrusion 3-5 of the cylindrical portion 3-3 with the small protrusion 2 of the leg piece 2-1.
The cap of the present invention is constructed by assembling the rib 3-2 so as to sandwich the leg piece 2-1 inserted into the recessed gap 3-4.

The protrusion 3-5 that has climbed over -2 is engaged with the inner surface of the small protrusion 2-2, and the bottom portion 3-6 is in contact with the inner top surface of the cap main body 2, and is connected to the tip 4 of the writing instrument. When the cap 1 is attached or detached, movement in the axial direction is inhibited.

せる。 As mentioned above, the cap main body 2 is hard,
Even if any soft plastic material is used, the engagement strength can be stably maintained to satisfy practicality, and the flexibility of the plastic material to be applied can be increased. In addition, with the above configuration, both members have no constituent elements that interfere with injection molding processing, and satisfy molding processability.
