DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod-like container for holding a rod-like material such as chalk, a correction stick, a color stick, a stick-like glue, and a stick-like eraser, and for delivering the rod-like material by a rotating operation. TECHNICAL FIELD The present invention relates to a technique for improving the retention, operability, etc.

[0002]

2. Description of the Related Art When black ink (hereinafter, chalk) used for writing on a blackboard used in a school or the like becomes shorter with use, it becomes difficult to hold it with a finger, and it becomes difficult to use it. Further, since the chalk is directly held by the finger, there is a problem that the hand becomes dirty. For this reason, conventionally, a holder for holding the chalk so as to be able to be fed is used.

[0003] A conventional choke holder is constructed, for example, as shown in FIG. That is, the chalk holder is
A cylindrical container 1; a cylindrical choke holder 2 which is slidably inserted into and held in the container 1; and a choke holder 2 which is attached to an outer peripheral position of the choke holder 2 in the container 1 and is always attached to the container. (1) a spring (not shown) that elastically urges in a direction to pull inward.

While the inner diameter of the tip of the container 1 is narrowed, the tip of the choke holder 2 is
The large-diameter portion 2 is locked so as to protrude from the distal end.
A is provided, and a plurality of cut grooves 2B extending in the axial direction are formed. Thereby, a gripping claw 3 that grips the chalk 5 is formed at the tip of the chalk holder 2. The rear end of the chalk holder 2 protrudes from the rear end of the container 1 and is configured as an operation unit 4 that presses the chalk holder 2.

[0005] The gripping claws 3 are elastically deformable. When the gripping claws 3 are inserted into the inner peripheral portion of the distal end of the container 1, the gripping claws 3 are close to each other and narrow, while the gripping claws 3 are closed. When the gripping claws 3 protrude outward from the distal end, the gripping claws 3 are separated from each other and spread. Therefore, the choke 5 inserted into the chalk holder 2 is positioned so that the gripping claws 3 are inserted into the inner peripheral portion of the distal end portion of the container 1 (in a state where the chalk holder 2 is pulled inward by the spring into the container 1). The user can be brought into a use state by gripping with the gripping claws 3 in the narrowed state. Further, if the chalk holder 2 is pressed to protrude outward from the tip of the container 1 (in a state where the choke holder 2 is pushed out of the container 1 by pressing the operation unit 4), the gripping claws 3 are spread. Then, the grip of the choke 5 can be released.

Accordingly, the chalk 5 is used in a state of protruding from the tip of the choke holder 2 by a desired length, and the length of the choke 5 protruding from the tip of the chalk holder 2 as the use of the choke 5 increases. As the length becomes shorter, the choke 5 is extended from the tip of the choke holder 2 so that the extended length can be adjusted.

Further, there has been known a rod-shaped material dispensing container which holds a rod-shaped material such as a correction rod, a color stick, a bar-shaped glue, a bar-shaped eraser and the like and rotates the rod-shaped material (Japanese Utility Model Laid-Open No. 5-58673). Gazette, Heikai 5-658
No. 79, JP-A-6-23791, JP-A-7-232495 and the like). This rod-shaped material feeding container is configured, for example, as shown in FIG.
When using the tail plug 1 provided at the rear end of the main body 11
5 is twisted in the forward direction to raise the push shaft 12,
The distal end of the push shaft 12 is connected to the lower end of the gripping body 16 and pushes up the gripping body 16 so that the rod-shaped material S projects from the distal end of the cylindrical body 13. When the bar-shaped object S is not used, the tail shaft 15 is twisted in the reverse direction to lower the push shaft 12, and the tip of the push shaft 12 is connected to the lower end of the grip body 16. By pulling down the body 16, the rod-shaped object is immersed in the cylindrical body 13.

[0008]

However, in the above-mentioned conventional choke holder, the choke holder 2
The configuration is such that the choke 5 inserted therein is simply gripped by the gripping claw 3 in the narrowed state with the gripping claw 3 inserted into the inner peripheral portion of the distal end of the container 1. Occasionally, when a pressing force is applied to the choke 5, the choke 5 easily retracts into the chalk holder 2, resulting in poor usability.

In addition, each time the chalk feeding length is adjusted, the chalk holder 2 is pressed to adjust the
It is necessary to adjust the length of the projection from the tip of the chalk holder 2 by pulling the choke 5 with a finger or the like at this stage by projecting outward from the tip of the choke holder 3 at this stage. There is a problem that the length of chalk feeding out cannot be easily adjusted with one hand, and the hands become dirty. Also, it is difficult to finely adjust the length of the choke 5, and it is difficult to make the length as desired.

Further, since the choke 5 is configured to be gripped only by the gripping claws 3, there is only one support point, and the support state is unstable. Inferior. Further, when the choke 5 becomes short, the supporting state becomes more unstable, and the extremely short choke 5 becomes unusable, so that the choke 5 cannot be completely used.

On the other hand, the rod-shaped material feeding container shown in FIG. 8 has a structure in which the rod-shaped material S is moved forward and backward by raising and lowering the push shaft 12 by the torsional rotation of the push shaft 12. , The length of the entire container is equal to the length of the
Chalk 5
When used as a holder, it is too long to use.
In addition, it can be said that this rod-shaped material feeding container has a large number of components and a complicated structure. Further, there is a problem that it takes time to rewind.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and is directed to a rod-like material delivery container for delivering a rod-like material by a rotating operation. The container has a simple structure, is compact, and has a support for the rod-like material. It is an object of the present invention to provide a stick-shaped material dispensing container which is excellent in the stability of the condition and excellent in the usability, and is particularly effective for dispensing black ink used for writing on a blackboard.
