Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to writing instruments for use with writing members (drawing leads, crayons for painting, fraypas, etc.) and cosmetic members (O-koku). , eyeliner, eyebrow ink, etc.).

[Conventional technology]

Conventionally, this type of writing instrument and cosmetic instrument (hereinafter referred to as a writing instrument, etc.) has been used, for example, to draw out the writing or cosmetic member itself from the tip of the barrel using a knock-type feeding device, or to draw out a part of the writing instrument, etc. There is one in which the member for writing or makeup is made to protrude from the tip of the barrel by rotating the member.

Many of the above-mentioned writing and cosmetic members are formed to be soft, and thin (formed) materials tend to break easily and are also consumed during use, so they are usually made with thick cores. There is.

Furthermore, there have been a number of disclosures in the past regarding feeding devices using a knocking operation, such as Japanese Utility Model Publication No. 13101/1983 by the applicant of the present invention. This is a two-stage knock type in which, in addition to a single knocking operation to feed out the lead, the tip of the barrel for writing can be retracted by a knocking operation.

Furthermore, in writing instruments, etc., in which a part of the writing instrument is rotated to protrude, it is often found in cosmetics such as lipsticks, and is caused by the engagement between a spiral groove and a protrusion or a spiral protrusion and a groove. It has been known for a long time.

[Problem to be solved by the invention]

As mentioned above, this type of writing or cosmetic member is soft, so when it is fed out by the feeding device, the gripping function and the subsequent pushing function, which are the functions of this type of device, will cause the member to The portion of the feeder that comes into contact with the device is scraped to some extent, resulting in the generation of scum, which remains nearby and impairs the smooth operation of the feeding device.

In addition, when storing the member inside the barrel after use, the feeding device releases the gripped state of the member and presses the tip of the member toward the inside of the barrel to store the member. be.

In this case, since some pressing force is required to house the member, there is a problem in that the tip of the member may be crushed at that time.

Furthermore, for convenience in use, this type of writing instrument, etc. has a part (
Hereinafter referred to as the written surface. ) is desirably kept constant with respect to the barrel, but the conventional feeding device does not have a function of actively keeping the stroke constant, and also does not have a function of actively keeping the stroke constant, and also does not have a function of rotating a part of the barrel. With this rotation, the member also rotates and protrudes from the barrel, so there is a problem that the stroke cannot be kept constant with respect to the barrel.

Therefore, in consideration of the above-mentioned problems, the present invention provides a writing instrument that allows the member to be smoothly drawn out, protects the tip of the member when stored, and furthermore, allows the writing surface to be kept in a fixed direction. Its purpose is to provide the following.

[Failure to solve the problem]

The push-out writing implement and cosmetic implement of the present invention support the knock member via a first elastic body (coil spring) that biases the knock member in a direction opposite to the direction in which the knock member is pushed down, and the inside of the barrel is moved along its longitudinal direction. A feeding device is supported by the main body via a second elastic body (coil spring) that biases in the opposite direction so as to be able to move in the opposite direction, and the feeding device is fed out by a knock operation of the feeding device. a pushing rod having a writing or cosmetic member attached to the tip thereof; and a holding member having a convex portion that moves in the downward direction of the feeding device and that fits into the hole of the barrel. an elastic member for writing, and the feeding device pushed down against the second elastic body is held in a predetermined position by the holding elastic member; In order to prevent the member from rotating with respect to the barrel, the writing member is attached to the extrusion rod via an attachment member, and an elastic protrusion is formed on the attachment member. A groove that abuts and is guided in the longitudinal direction is formed on the inner circumferential surface of the shaft cylinder.

[For production]

By pressing the knock member in the downward direction,
The feeding device moves downward against the biasing force of the second elastic body, and the holding elastic member holds the feeding device in its moved position. At this time, the pushing rod, which has moved downward together with the feeding device, causes the writing or cosmetic member to protrude from the tip of the barrel, thereby making the writing instrument etc. ready for use. Next, in this state, by knocking the knocking member against the biasing force of the first elastic body, the feeding device is operated, and the member that has been consumed during use is projected by a predetermined length.

Moreover, after use, by operating the holding elastic member to release the holding of the feeding device and using the urging force of the second elastic body to return the feeding device to the normal position, Accordingly, the member is housed inside the shaft cylinder together with the extrusion rod.
