Description

[Detailed description of the invention]

[0001]

[Industrial application] Writing instruments such as ball pens and sharp pencils, cosmetics such as eyeliners and lip colours, erasing tools such as correction fluids, solid correction tools and erasers, and fitting of caps in applicators, etc. Regarding the structure.

[0002]

2. Description of the Related Art In the above, the cap is a general one. What is covered is not only a pen tip and an application tip, but also an eraser attached as an accessory to the rear end of a sharp pencil.

[0003] In such a device, a clip is also common. There are various types of attachments, such as on the front end and rear end of the barrel, or on the cap. In the following, in the case of having a clip, that is, when the main body is a cap,
The cap as the main body is referred to as a parent cap, and the cap fitted to the parent cap is referred to as a child cap for distinction.

[0004]

[Problem to be Solved by the Invention] When the cap is fitted, the fitting force is not too large, and when the cap is fitted, the cap does not rotate or rattle unnecessarily with respect to the main body. Is required. The purpose of the present invention is to provide a means for responding to these requests.

[0005]

According to the present invention, there is provided a structure in which a cap is fitted to a body having a clip, a slit extending from an open end is provided in the cap, and a base protruding from the body of the clip is inserted into the slit. The gist is a cap fitting structure formed by this.

[0006]

FIG. 1 shows an example. Reference numeral 1 denotes a cap, which has a slit indicated by reference numeral 1a.
The slit 1a is provided over an appropriate length from the opening end 1b of the cap 1. Even if the width is constant,
Further, different parts may be used. Such a cap 1 can be easily obtained by injection molding of a suitable synthetic resin such as polyethylene, polypropylene and acrylic resin.

Reference numeral 2 denotes a main body, and a clip 3 is attached. The clip 3 may be an integral part of the main body 2 or a separate part. Like the cap 1, it can be easily obtained by appropriately injection molding a synthetic resin. Reference numeral 3a
Indicates a base of the clip 3 projecting from the main body 2. Although the illustrated projecting base 3a is narrow, the shape is appropriate. Incidentally, the ball portion of the clip 3, that is, the portion for holding the pocket cloth or the like is on the lower side of the drawing, not shown.

[0008] Reference numeral 4 denotes a crown material such as a writing material, a cosmetic material, and a coating material. Specific examples include a crayon, a pass, an eraser, a solid correction tool such as handwriting, a lip color, and the like. It may not be very common for the clip 3 to be located near such a use 4. However, there are many existing ones such as an eraser attached to the rear end of a sharp pencil so that it can be fed out.

The cap 1 is fitted on the main body 2. Press fit,
The type of fitting such as uneven fitting is appropriate. At the time of this fitting,
The slit 1a of the cap 1 is expanded so as to exert an elastic force as necessary, such as variation in molding dimensions, so that the fitting force does not become too large. Further, the projecting base 3a of the clip 3 is inserted into the slit 1a. This insertion may involve a mating force. This insertion prevents the cap 1 from rotating with respect to the main body 2 even if both the cap 1 and the main body 2 have circular cross sections. The cap 1 and the main body 2 may of course be of a cross-sectionally irregular shape capable of preventing rotation.

Next, another example will be described with reference to FIG.
This is an example of a structure in which the main body is a cap, that is, a structure in which a child cap is fitted to a parent cap. In many cases, the size of the child cap cannot be too large for the parent cap due to design requirements. As a result, the fitting amount (stroke) becomes smaller, so that certainty of fitting is particularly required. Therefore, it can be said that the present invention is an example of a preferable example.

In FIG. 2, the same reference numerals 1 to 4 are used for the basically same parts as those in FIG. Reference numeral 5 denotes a writing body illustrated with a ball pen body in mind, and the parent cap 2 as a main body has an elastic body 6 for a pen tip seal. Although the child cap 1 has the hole 1c, it is for preventing suffocation when an infant or the like accidentally swallows the child cap 1.

In FIG. 2, the child cap 1 is further provided with a portion indicated by reference numeral 1d. The abutment for the clip 3, as can be seen from the presence of this abutment 1d, if the child cap 1 has a slit 1
If a is not formed, the fitting amount of the child cap 1 to the parent cap 2 becomes extremely small. That is, a large amount of fitting can be ensured by an amount corresponding to the insertion of the protruding base 3a of the clip 3 from the parent cap 2 into the slit 1a. In addition, the abutting portion 1d may be formed in an appropriate shape, and may have, for example, an overall series with the clip 3. In addition, of course, the amount of insertion of the projecting base 3a of the clip 3 into the slit 1a may be appropriate. In FIG. 2, the projecting base 3a is inserted to the innermost part of the formed slit 1a.

In FIG. 2, assuming that the parent cap 2 can be fitted to the rear end (the lower end in the drawing; not shown) of the writing body 5 in writing use, “parent cap 2-writing body 5 It has three fitting portions of “the front end”, “the parent cap 2-the rear end of the writing body 5”, and “the parent cap 2-the child cap 1”. In this case, it is preferable to set the fitting force in the order shown here. That is, "parent cap 2-child cap 1"
Of the child cap 1
Due to the slit 1a, even with such a relatively small fitting force, a sufficiently stable fitting can be performed.

[0014]

The cap fitting structure of the present invention is a structure in which a cap is fitted to a main body having a clip, a slit extending from an open end is provided in the cap, and a base protruding from the main body of the clip is provided in the slit. Since the cap is inserted, the fitting force when fitting the cap is not excessively large, and the cap does not rotate or rattle unnecessarily with respect to the main body in the fitted state. Will be stable.
