Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stick-shaped object feeding container in which a stick-shaped eraser, a lipstick, a correction stick, a writing lead, a fluorescent lead, a stick-shaped paste, a path, and the like stick out from the tip of a cylindrical cap by rotating.

[0002]

[Prior Art]

 As a conventional rod-shaped material feeding container, there is, for example, the one disclosed in Japanese Utility Model Publication No. 57-132598. In this conventional example, a mechanical pencil having a fitting groove is pivotally attached to a lower portion of a main body, and an upper portion of the mechanical body having a spiral groove on an inner surface is rotatably attached.

Then, a core tube having open slits opened on the head side at positions opposite to each other is inserted into the upper and lower parts of the mechanical pencil body so that the convex portions fit into the fitting grooves, and the spiral groove and the open groove are opened. An eraser receiver having a protrusion engaged with the slit is provided in the core tube, and a rod-shaped eraser is fitted to the eraser receiver.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional example, the rod-shaped eraser can be delivered from the head by rotating the upper part of the main body, but the protrusion of the eraser receiver reaches the upper end of the spiral groove and stops, and the eraser is not delivered. When it is no longer possible to use the eraser, it is extremely difficult to remove the remaining eraser in the eraser receiver because the eraser is fitted in the eraser receiver.

Further, since the upper part of the core tube is curved inward to prevent rattling when the eraser is used, not only is the eraser easily broken, but it cannot be used independently as a cassette because it is integrated with a writing instrument. There are issues such as.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the container of the present invention has a cylindrical cap 2 having an open spiral groove 1 opened at one end on an inner surface thereof, and an open slit 3 opened at the head side as shown in FIG. The inner cylinder 4 is rotatably fitted into the inner cylinder 4 so that it cannot be moved in the axial direction, and the open slit 3 and the open spiral groove 1 are engaged with the holding piece 5 and the projecting portion 6, respectively. A bar 8 is held between the holding pieces 5.

[0007]

[Action]

 When the inner cylinder 4 or the cylindrical cap 2 is rotated with respect to the cylindrical cap 2 or the inner cylinder 4, the holding piece 5 and the projecting portion 6 of the rod-shaped object receiving stand 7 respectively cause the open slit 3 and the cylindrical cap of the inner cylinder 4. Since it is engaged with the open spiral groove 1 of No. 2, the rod-shaped object receiving base 7 is guided along the open spiral groove 1 by the open slit 3 and is moved in the axial direction, so that the bar-shaped object receiving base 7 is held by the holding piece 5. The sandwiched rod-shaped object 8 is projected and retracted from the tip of the tubular cap 2 according to the rotating direction.

When the rod-shaped object 8 is consumed by use and remains as the remaining portion, the holding piece 5 of the rod-shaped object receiving stand 7 can be made to project from the tip of the tubular cap 2, so that the rod-shaped object held by the holding piece 5 can be held. The rest of the material can be removed very easily.

Further, since the rod-shaped object 8 is held in the inner cylinder 4 over the entire length, it does not rattle during use and is not liable to break, and it is also used alone as a rod-shaped object feeding container. Not only can it be used, but it can also be used by being connected to the writing instrument 14.

【Example】

 FIG. 1 is a vertical cross-sectional view showing one embodiment of the container of the present invention connected to a writing instrument head, FIG. 2 is a cross-sectional view taken along the line AA of this embodiment shown in FIG. 1, and FIG. FIG. 3 is a partial cross-sectional view showing a first example of a state where the rod-shaped object receiving base has reached the uppermost position, and FIG. 3B is a partial cross-sectional view showing the same second example.

In FIG. 1, reference numeral 2 denotes a cylindrical cap, and an inner surface thereof is provided with an open spiral groove 1 open at one end. Reference numeral 4 denotes an inner cylinder, and open slits 3 open to the head side are formed at opposite positions. An inner cylinder 4 is rotatably fitted into the cylindrical cap 2 so as not to move in the axial direction.

A means for rotatably fitting the inner cylinder 4 so that it cannot move in the axial direction is, for example, provided with an inner step 9 at the rear end of the cylindrical cap 2 and slidable on the end of the open spiral groove 1 of the cylindrical cap 2. A head topper 10 in contact with the inner cylinder 4 is provided on the outer periphery of the head of the inner cylinder 4, and a rear stopper 12 is provided at the rear part of the inner cylinder 4 by a notch 11 slidingly contacting the outer surface of the inner step portion 9 of the tubular cap 2.

A rod-shaped object receiving stand 7 in which two holding pieces 5 and a projecting portion 6 are engaged with the open slits 3 and the open spiral groove 1 respectively is provided in the inner cylinder 4, and both of the rod-like object receiving stands 7 are held. A stick-shaped eraser 8 is sandwiched between the pieces 5.

To assemble the inner cylinder 4 to the cylindrical cap 2, the base 13 of the inner cylinder 4 is inserted from the end of the open spiral groove 1 of the cylindrical cap 2, and the slope of the rear stopper 12 is the inner slope of the inner step 9. The rear stopper 12 bends inward when pressed against the inner step portion 9 and comes into contact with the outer surface of the inner step portion 9 at the point beyond the inner step portion 9 and at the same time the head stopper 10 abuts against the end of the open spiral groove 1. Finish the attachment.

When the base portion 13 of the inner cylinder 4 is rotated with respect to the cylindrical cap 2 or the cylindrical cap 2 is rotated with respect to the inner cylinder 4 in the present embodiment having the above-described configuration, the holding piece 5 of the rod-shaped object receiving base 7 is rotated. Since the projections 6 are engaged with the open slit 3 of the inner cylinder 4 and the open spiral groove 1 of the tubular cap 2, the rod-shaped object support 7 is guided along the open spiral groove 1 to the open slit 3. As a result, the rod-shaped rubber 8 held by the holding piece 5 of the rod-shaped object receiving stand 7 is moved in the axial direction and protrudes or retracts from the tip of the tubular cap 2 depending on the rotation direction.

When the stick-shaped eraser 8 is consumed by use and left as a remaining portion, when the protrusion 6 of the stick-shaped object support 7 is rotated until it hits the head stopper 10 as shown in FIG. Since it is in a state of protruding from the tip of the cylindrical cap 2, the remaining portion of the rod-shaped eraser 8 held by the holding piece 5 can be removed very easily.

When the gripping piece 5 projects from the tip of the tubular cap 2, the gripping piece 5 is preliminarily shaped so as to warp outward as shown in FIG. 3 (B). Is easier and preferable.

Further, since the rod-shaped eraser 8 is held in the inner cylinder 4 over the entire length, it does not rattle during use and is not liable to break, and it is used alone as a rod-shaped object feeding container. Of course, it is possible to use it by connecting it to the writing instrument 14.

For example, as shown in FIG. 1, a front portion of a connecting member 17 having a partition 18 at the center of the inside is fitted to a core tank or refill 16 of the writing instrument 14, and the outer periphery of the connecting member 17 and the outer cylinder 15 are fitted. A connecting member 17 is fitted in the outer cylinder 15 so as to be axially movable and non-rotatable, with each of the inner circumferences being polygonal.

The tubular cap 2 constituting the container of the present invention is inserted into the outer cylinder 15 from the base 13 of the inner cylinder 4, and the base 13 is detachably fitted into the rear part of the connecting member 17 to be connected. The rear inner circumference of the connecting member 17 and the outer circumference of the base 13 of the inner cylinder 4 are polygonal, and the base 13 of the inner cylinder 4 is axially movable and non-rotatably fitted to the connecting member 17.

In this way, when the present embodiment is connected to the writing instrument 14, when the cylindrical cap 2 is rotated with respect to the outer cylinder 15, the rod-shaped eraser 8 is rotated from the tip of the cylindrical cap 2 in the same manner as above. It can appear and disappear depending on the direction.

When the head of the tubular cap 2 is knocked, the core tank or the refill 16 is advanced by the base 13 via the connecting member 17 and the writing core is moved to the outer cylinder 15 in the same manner as a known knock-type writing instrument. It can be used for writing by protruding from the tip of and can be retracted by knocking again.

In the present invention, it is needless to say that the number of open slits 3 and the number of sandwiching pieces 5 are not limited to two in the embodiment.

[0024]

[Effect of the device]

 As described above, according to the present invention, since the sandwiching piece 5 of the rod-shaped object receiving base 7 projects from the front end of the tubular cap 2, the rod-shaped object remaining portion sandwiched by the sandwiching piece 5 can be extremely easily removed. it can.

Also, since the rod-shaped object 8 is held in the inner cylinder 4 over the entire length, it does not rattle during use and is not liable to break, and it is also used as a rod-shaped object feeding container independently. Not only can it be used, but it can also be used by being connected to the writing instrument 14.
