DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for writing instruments, makeup tools, and the like, and more particularly to a double cap structure having an inner cap inside an outer cap, which can prevent suffocation even if accidentally swallowed and clogged in the throat. About the cap.

[0002]

2. Description of the Related Art As shown in FIGS.
If the clip 20 is attached to 9, a gap 21 serving as an air passage is generated between the cap 19 and the clip 20,
There is little danger of suffocation if swallowed and clogged in the throat.

[0003] However, if the clip cannot be attached due to a design or functional problem, a double cap structure must be provided to secure a ventilation path.
That is, a ventilation path must be provided between the outer cap and the inner cap.

[0004] By the way, in the case of a writing implement or a makeup tool using a tip or a brush as a coating member, it is necessary to increase the diameter of a fiber bundle to be a tip or a brush so that the tip or the brush contains sufficient ink or cosmetic liquid. Therefore, the diameter of the tip for attaching the tip and the brush must be large.

On the other hand, since the outer diameter of the cap is preferably the same as the outer diameter of the shaft due to design problems, the outer diameter of the cap of a writing instrument or a makeup tool using ear tips or brushes also increases.

In a double-structured cap, it is necessary to increase the difference between the inner diameter of the outer cap and the outer diameter of the inner cap in order to ensure a sufficient ventilation path. Since the outer diameter of the outer cap cannot be reduced so much as to be accommodated, it is necessary to increase the inner diameter of the outer cap. However, as described above, the outer diameter of the outer cap must be increased in accordance with the outer diameter of the shaft, and if the outer diameter is further increased, the usability and appearance deteriorate, and the outer cap is stored in a writing instrument case or the like. Also have disadvantages such as difficulty.

[0007] That is, in a writing instrument or a makeup tool using a tip or a brush as an application member and a double structure of a cap, if an attempt is made to suppress an increase in the outer diameter of the cap, an air passage for avoiding suffocation is provided. It was difficult to secure enough.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention is to be applied to a writing instrument or a makeup tool using a tip or a brush as a coating member, and has a double cap structure of an inner cap and an outer cap. Regardless, an object of the present invention is to provide a cap capable of suppressing an increase in the outer diameter of the outer cap and securing a sufficient ventilation path so as not to suffocate even if the outer cap is swallowed and clogged in the throat.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a cap such as a writing instrument and a makeup tool of the present invention has a double cap structure in which an inner cap 8 is provided inside an outer cap 1. A vent hole 3 is formed in the top plate 2 of the outer cap 1, and an axial ventilation groove 5 is provided on the inner surface of the outer cap 1 from the opening side edge 4 toward the top plate side. On the outer surface of the cap 8, there is provided a circumferential ridge 10 for retaining which can be engaged with the convex portion 9 provided on the inner surface of the outer cap 1, and the ridge 10 of the inner cap 8 is provided inside the ridge 10. And a ventilation cut-out 12 for opening the outside.

If the cap has a double structure, the tip of an application member such as a spike or a brush may be erroneously inserted into a gap between the inner cap 8 and the outer cap 1, which is prevented. For this reason, it is preferable that the opening side edge 13 of the inner cap 8 is slightly protruded from the opening side edge 4 of the outer cap 1 in a state where the writing tool or the makeup tool is off the shaft.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The writing implement of the embodiment shown in FIGS. 1 to 4 will be described below. First, in the drawing, reference numeral 1 indicates an outer cap. One end of the outer cap 1 is open and the other end is closed by a top plate 2. The top plate 2 is provided with a discontinuous circular ventilation hole 3 for opening the internal space of the outer cap 1 to the outside. Has been established.

The outer cap 1 is provided with an axial ventilation groove 5 extending from the opening side edge 4 to a substantially middle portion in the longitudinal direction at a plurality of positions on the inner surface in the circumferential direction.

Further, the outer cap 1 has an opening side edge 4.
At a plurality of locations in the circumferential direction on the inner surface close to, a projection 7 that can be locked to the writing instrument shaft 6 is provided so as not to coincide with the position of the ventilation groove 5, and the circumferential direction on the inner surface slightly deeper than that is provided. Also at a plurality of locations, there are provided projections 9 to be locked to an inner cap 8 described later so as not to coincide with the position of the ventilation groove 5.

The inner cap 8 is, of course, the outer cap 1
Is housed inside. The inner cap 8 is provided with a circumferential ridge 10 that is engaged with the inside of the convex portion 9 of the outer cap 1 at a substantially middle portion in the longitudinal direction on the outer surface.

A spring 11 is provided between the ridge 10 of the inner cap 8 and the top plate 2 of the outer cap 1. Although the inner cap 8 is pressed toward the opening side of the outer cap 1 by the spring 11, since the ridge 10 of the inner cap 8 is locked to the projection 9 of the outer cap 1 as described above, the inner cap 8 is pressed. Is secured to the outer cap 1.

At a plurality of locations in the circumferential direction of the ridge 10 of the inner cap 8, there are provided through holes 12 for ventilation in the axial direction for opening the inside and the outside of the ridge 10. The number of the cutouts 12 is different from the number of the protrusions 9 provided on the outer cap 1. This is because, if the number of the protrusions 9 and the number of the cutouts 12 match, the positions of the protrusions 9 and the cutouts 12 match, and the protrusions 9 may block the cutouts 12 and obstruct ventilation.

In the state where the cap is removed from the writing instrument shaft 6, as shown in FIG.
The opening side edge portion 13 of the inner cap 8 is designed to protrude slightly outward.

When the cap is detached from the writing instrument shaft 6, the opening area of the gap 14 formed between the outer cap 1 and the inner cap 8 at the opening side edge 4 of the outer cap 1 is 6. It is designed to be 8 mm ² or more. More preferably, it is 10 mm ² or more. By having this opening area, 8 l / min (1.33
(kPa, RT) or more, and it is possible to avoid suffocation even if accidentally swallowed and clogged the throat. The outer diameter of the outer cap 1 is equal to the outer diameter of the writing instrument shaft 6 and is set in a range of 12 to 15 mm.

As shown in FIG. 4, the cap is attached to the writing implement shaft 6.
When the outer surface of the front end of the front cover is put on the tapered front shaft portion 15, the front end portion of the front shaft portion 15 and the tip 16 protruding from the front shaft portion 15 are inserted into the inner cap 8. The inner surface of the inner cap 8 has a sealing portion 1 which comes into airtight contact with the outer peripheral surface of the tip shaft portion 15.
7 are provided. Then, the inner cap 8 is pushed by the front shaft portion 15 and compresses the spring 11 while the outer cap 1 is compressed.
, The projection 18 provided on the tip shaft 15 is locked to the projection 7 of the outer cap 1, and the closed state is maintained.

Although the above embodiment relates to a writing instrument, the present invention can of course be applied to a makeup instrument.

[0021]

The structure of the cap of the present invention, such as a writing instrument or a makeup tool, is as described above. In addition to the ventilation groove 5 provided on the inner surface of the outer cap 1, ventilation is provided on the ridge 10 on the outer surface of the inner cap 8. Of the outer cap 1
Since a sufficiently wide air passage can be secured between the inner cap 8 and the inner cap 8, there is an effect that suffocation can be surely avoided even if swallowed by mistake and clogged in the throat. Further, despite the double cap structure having the outer cap 1 and the inner cap 8, the ventilation path is formed by the ventilation groove 5 provided on the inner surface of the outer cap 1.
And a notch 12 provided on a ridge 10 on the outer surface of the inner cap 8.
With this configuration, the gap between the outer cap 1 and the inner cap 8 does not need to be widened, so that an increase in the outer diameter of the outer cap 1 can be suppressed, thereby improving usability and portability. The effect is obtained. Also,
As described in claim 2, the opening side edge 13 of the inner cap 8 projects slightly outward from the opening side edge 4 of the outer cap 1 in a state of being removed from the axis of the writing instrument or the makeup tool. Thus, when attached to the shaft of a writing instrument or a makeup tool, it is possible to prevent the tip of the hand or the brush from being inserted into the gap between the outer cap 1 and the inner cap 8 when the hand gets crazy.
