Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a writing instrument cap with a blade that can open an envelope.

[0002]

[Prior art]

 I used to open a conventional envelope, but I often don't have a pencil or a ballpoint pen, and I often insert the tip of a pencil or a ballpoint pen into the enclosed crease and open it or tear it by hand, which is inconvenient. Not only that, but also the opening was dirty.

[0003]

[Problems to be solved by the device]

 Even if you don't have a place to open a letter, writing instruments are often placed in a chest pocket of a suit, placed on a desk or in many other places, so a writing blade can be freely inserted into and removed from the writing instrument cap. It will be convenient for you to open the letter without damaging your clothes or hands.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, we devised a writing instrument cap for opening that has a blade that can be inserted and removed freely inside the clip.

[0005]

[Structure and action]

 Next, the structure of claim 1 of the present invention will be described. One end of a writing instrument cap that has one end connected to the outer surface of a shell-shaped hollow cap body 2 having a writing instrument insertion port 1 on the bottom and a clip 3 attached approximately parallel to the bus body of the cap body in the insertion port direction With the protruding knife blade 4, the blade tip 8 of the small press blade 7 whose other end is the button 6 via the neck portion 5 is formed in the clip with the blade surface perpendicular to the clip length direction. As the elastic body to be used in the construction of the writing instrument cap in which the front side of the clip 3 and the neck section 5 are connected with an elastic body after being inserted into Cap 15 ・ Rubber tube 16 ・ Metal leaf spring 17 ・ Piano wire coil spring such as rubber, plastics, metal and other materials with repulsive force can be used in the form of leaf panel, coil spring, disc spring etc. .

In FIG. 1, a small push blade 7 with a button 6 is attached to the clip 3 so that the blade 4 is pushed up by the repulsive force of the rubber cap 15 and hidden inside the clip 3 attached to the cap body 2. It is a side view of the writing instrument cap of the 1st embodiment which did.

2 and 3 are enlarged partial cutaway sketches of the vicinity of the small press blade. When the button 6 is not pressed, the blade 4 is lifted by the repulsive force of the rubber cap 15 as shown in FIG. Since it is stored in the hole 9 of the clip 3, it does not hurt clothes or hands. When opening the envelope, hold the envelope under the clip and push the button while moving the envelope to open it. At this time, the blade 4 can come out from the inner surface of the clip 3 to cut the envelope as shown in FIG.

FIGS. 4 and 5 are partially cutaway sketches of the second embodiment, in which a rubber tube is used as an elastic body, in which the vicinity of the small press blade is enlarged, and when the button 6 is not pressed, it is as shown in FIG. Since the blade 4 is lifted by the repulsive force of the rubber tube 16 and is housed in the hole 9 of the clip 3, it does not hurt clothes or hands. When opening an envelope, hold the envelope under the clip and push the button while moving the envelope to open it. At this time, the blade 4 can protrude from the inner surface of the clip 3 to cut the envelope as shown in FIG.

FIG. 6 is a side view of a third embodiment in which the blade 4 can be stored in the hole 9 of the clip by utilizing the repulsive force of the leaf spring 17. You can cut the envelope by pushing the button 6 and pulling out the blade.

The structure of claim 2 of the present invention will be described. One end is connected to the outer surface of a cannonball-shaped hollow cap body 2 having a writing instrument insertion port 1 on the bottom, and a clip 3 with a different thickness in the longitudinal direction is approximately parallel to the bus bar of the cap body 2 in the insertion port direction. In the attached writing utensil cap, the cutting edge 8 of the small pressing blade 7 having the cutting knife blade 4 at one end and the button 6 at the other end via the neck portion 5 at the right angle to the long side of the clip. Then, the writing instrument cap in which the blade 4 is slidably inserted into the slit hole 10 bored in the clip length direction from the front side, and the blade 4 is attached to and removed from the rear surface of the slit hole 10 is provided.

FIG. 7 shows the writing tool cap of the fourth embodiment in which the blade 8 with the button 6 is slid in the length direction of the clip 3 so that the cutting edge 8 is exposed inside the clip 3. It is a side view of a state in which it is covered, and when the button 6 is lifted toward the tip of the cap body 2, the blade edge 8 is housed in the hole of the clip 3, and the button 6 is pushed toward the tip of the clip 3 with a finger. When it is slid, the blade 4 comes out from the inner surface of the clip 3 and can be opened as shown in FIG.

The configuration of claim 3 of the present invention will be described. One end of a writing instrument cap, in which one end is connected to the outer surface of a cannonball-shaped hollow cap body 2 having a writing instrument insertion port 1 on the bottom and a clip 3 is attached substantially parallel to the generatrix of the cap body 2 in the insertion direction, The blade tip 8 of the small rotary blade 12 having the rotary shaft 11 protruding to both sides in the direction orthogonal to the blade surface in the middle of the protruding knife blade 4 and the button 6 at the other end With a writing instrument cap, the bearing groove 13 is rotatably inserted into a hole 14 with a bearing groove formed in the clip 3 so that the bearing groove 13 is oriented in the length direction of the clip, and the blade 4 is attached to and removed from the rear surface of the hole 14 with a bearing groove. is there.

FIG. 9 shows a plan view and a side view of the writing instrument cap according to the fifth embodiment. FIG. 10 is an enlarged plan view and side view of the small rotary blade 12 with the button 6, and FIG. 11 shows an AA cross section, a BB cross section, and a CC cross section. These are the states in which the blade 4 is stored. The small rotary blade 12 with a button is inserted into the hole 14 with the bearing groove formed in the clip 3, and the rotary shaft 11 is fitted into the bearing groove 13. By moving the button 6, the small rotating blade 12 is rotated to allow the blade 4 to be freely inserted and removed. When the button 6 is rotated to the left as indicated by the arrow in the C-C sectional view, the blade comes out as shown in FIG. 12 and the opening 20 of the envelope 19 can be cut. At this time, it is necessary to arrange the envelope so that it is slanted with respect to the paper direction and pulled out completely. FIG. 13 is a sketch drawing when the envelope 19 is opened.

[0014]

[Effect of device]

 As described in detail above, the writing instrument cap of the present invention safely stores the blade for opening the envelope, and does not damage clothes or hands. If necessary, the blade can be easily pulled out to open the envelope. Also, since the writing instruments are placed everywhere, it can be widely used to open envelopes.
