This invention relates to a container for dispensing rod-like objects that can be extended and retracted.

[Conventional technology]

Conventional erasers, crayons, pastels, etc. are used by cutting out the outer paper little by little and removing the contents little by little, while eyebrows, pencils, etc. are sharpened with a knife or pencil sharpener and the core is removed little by little. I found something to use.

[Problem that the invention attempts to solve]

However, when using the above-mentioned conventional sticks to remove the contents, it is necessary to scrape or cut the paper, so there is a problem of over-shaving or cutting the paper too much, and after centering, the sticks are protected. In order to prevent contamination of the stick itself and other objects, a cap is attached or placed in a case, so it is necessary to attach and detach the cap, take it out of the case, and store it in the case each time it is used. There was a problem that not only was it lacking in convenience, but there were also many opportunities to get hands and other objects dirty.

[Means for solving problems]

The present invention was devised in view of the above-mentioned problems, and provides a rod-shaped part dispensing container that allows the above-mentioned stick-shaped part to be paid out from the tip by a knock operation and then retracted into the interior after use. It is.

That is, in the present invention, an inner cylinder 2 is slidably inserted into an outer cylinder 1, and an elastic body 3 such as a knock spring that acts in the axial direction is provided between the inner cylinder 2 and the outer cylinder 1. A chuck 4 is provided at the tip of the chuck 4, and a chuck tube 5 that is locked to the tip of the outer tube 1 is inserted between the chuck 4 and the outer tube 1. A connecting hole 6 is provided at the rear of the chuck tube 5. At the same time, the part of the outer cylinder 1 facing the connecting hole 6 is provided with an elasticity imparting member 9 that comes into contact with the rod-shaped object 8 in the inner cylinder 2 through the connecting hole 6 and the notch 7 of the chuck 4. It has a structure in which an inserting part 10 is slidably connected to the hole 6 and is provided therein.

[Effect]

Insert the rod-shaped object 8 from the rear end of the inner cylinder 2, hold the outer cylinder 1 by hand, and knock the rear end of the inner cylinder 2, and push it in the axial direction against the elastic body 3 such as a knock spring or by elastic force. When the chuck 4 is moved to the tip of the inner tube 2, the chuck 4 at the tip of the inner tube 2 opens and closes due to the movement of the chuck tube 5, and the chuck 4 allows the rod-like object 8 to be fed out from the tip and used.

In this case, the elasticity imparting member 9 prevents the rod-like object 8 from falling off due to the elastic force of the elasticity imparting member 9 when the chuck 4 is opened, and also prevents the rod-like object 8 from falling off when the chuck 4 returns from the open/closed state to the closed state. It also serves to prevent the rod-shaped object from being pulled back.

When the number of sticks 8 decreases, it is sufficient to perform a knock operation and pay out the sticks 8 by that amount.

Furthermore, in order to retract the rod-shaped object 8, by knocking the rear end of the inner cylinder 2, the chuck 4 opens against the elastic body 3 such as a knock spring, and in this state, the connecting hole 6 of the chuck cylinder 5 is opened. and an elasticity imparting member 9 that comes into contact with the rod-shaped object 8 through the notch 7 of the chuck 4.
It can be retracted by pushing the tip of the rod-shaped object 8 against the frictional force.

〔Example〕

Embodiments of the present invention will be described based on the drawings.

FIG. 1 is a sectional view showing an embodiment of the container of the present invention;
FIG. 2 is a cross-sectional view taken along the - line in FIG. 1 in a locked state.

In FIGS. 1 and 2, 1 is an outer cylinder, and 2 is an inner cylinder fitted into the outer cylinder 1. A chuck 4 is provided at the tip of the inner cylinder 2. In this example, the chuck 4 is divided into two parts as shown in the third figure, but it may be divided into three parts as long as it is appropriately divided. 7 is a notch part of the chuck.

A chuck tube 5, which is locked to the tip of the outer tube 1, is fitted between the chuck 4 and the outer tube 1. At the rear of the chuck tube 5, connection holes 6 are provided at opposing positions as shown in the fourth figure, and in the portion of the outer tube 1 that faces each connection hole 6, each connection hole 6 and the connection hole 6 of the chuck 4 are provided. An elasticity imparting member 9 that comes into contact with the rod-shaped object 8 in the inner cylinder 2 through the intake part 7 and an inner insertion part 10 that is slidably and irremovably connected to each connecting hole 6 are provided. .

Reference numeral 11 denotes a retainer provided on the inner periphery of the rear end of each connecting hole 6 to prevent each inner insertion portion 10 from being removed after being inserted into each connecting hole 6, and the outer edge is chamfered to facilitate insertion. . In order to facilitate insertion of the insert 10, the opposing edges of the insert 10 may also be chamfered.

A knock spring 3 acting in the axial direction is provided between the inner cylinder 2 and the outer cylinder 1. In this example, a knock spring 3 is inserted between the spring receivers 12 of each inner insertion portion 10 of the outer cylinder 1 and the spring receivers 13 of the inner cylinder 2. If the spring receiver 12 of each inner part 10 is not sufficient as a spring receiver, a spring receiver ring plate may be used in contact with the spring receiver 12, or as shown in the imaginary line shown in FIGS. 5 and 6 b. It is preferable to provide a spring receiver 14 at a position perpendicular to the spring receiver 12 of each insert 10. In this case, a slit is provided in the portion of the chuck tube 5 that faces each spring receiver 14.

In this embodiment, the elasticity imparting member 9 is a spring part integrated with the knock spring 3 as shown in FIGS. 1 and 2, but it may also be a separate plate spring, or as shown in FIG. The elastic body provided between the knock spring 3 and the spring receiver 12 may be made of rubber, for example.

In the embodiment configured as described above, the rod-shaped object 8
is set as follows. As the rod-shaped object 8, eraser, pencil lead, crayon lead, pastel lead, eyebrow lead, etc. can be used, and the external shape is round.

This completes the setting of the rod-shaped object 8, but those who find this setting cumbersome may use the container of the present invention in which the rod-shaped object 8 is already set.

To feed out the rod-shaped object 8, hold the outer cylinder 1 by hand,
When the rear end of the inner cylinder 2 is pushed against the knob spring 3, the rod-shaped object 8 held by the chuck 4 at the tip of the inner cylinder 2 is moved by a certain amount, and the chuck cylinder 5 is also pushed out of the connecting hole 6. The retainer 11 moves forward until it hits the inner insertion part 10 of the outer cylinder 1, and the chuck 4 opens. At this time, the elasticity imparting member 9 appropriately presses and attaches the rod-shaped object 8, preventing the rod-shaped object 8 from coming out and returning. is prevented.

Next, the inner cylinder 2 moves backward by the spring force of the knock spring 3, and as the chuck 4 moves backward, the chuck cylinder 5 moves backward until it is locked at the tip of the outer cylinder 1, and the chuck 4 moves backward.
is inserted into the chuck cylinder 5 and closed, and the rod-shaped object 8 is held down together with the elasticity imparting member 9.

Thereafter, by repeating the knock operation, the above operation is repeated, and the rod-shaped object 8 can be drawn out from the tip and used.

When the number of sticks 8 decreases, it is sufficient to perform a knock operation and pay out the sticks 8 by that amount.

In addition, in order to retract the rod-like object 8, the rear end of the inner tube 2 is knocked and pushed against the knock spring 3 to open the chuck 4, and the rod-like object 8 is loosely inserted into the notch 7 of the chuck 4. Since the elasticity imparting member 9 is in contact with the rod-shaped object 8, by pushing the tip of the rod-shaped object 8, it can be slid and retracted without being affected by the moderate elastic force of the elasticity imparting member 9.

When the stick 8 is used up, it can be replenished in the same way as when setting the stick. Alternatively, a new container of the present invention in which rod-shaped objects are already set may be used.

In the present invention, since the elasticity imparting member 9 is in contact with the rod-shaped object 8 with a moderate elastic force, the advancement of the rod-shaped object 8,
It is possible to move backward relatively smoothly and reliably, and variations in the outer diameter of the rod-shaped object 8 can be absorbed.

[Effect of the invention] As described above, according to the invention, the chuck 4 can be detached from and inserted into the chuck cylinder 5 by operating the notch at the rear end of the inner cylinder 2 with the rod-shaped object 8 set in the inner cylinder 2. The rod-like object is extremely simple, as it can be fed out little by little by opening and closing the inner cylinder 2, and can be retracted by pushing the rear end of the inner tube 2 to open the chuck 4 and pushing the tip of the rod-like object 8. A dispensing container can be provided.

In addition, since the elasticity imparting member 9 contacts the rod-shaped object 8 with a moderate elastic force, the rod-shaped object 8 can be moved forward and backward appropriately, smoothly and reliably, and variations in the outer diameter of the rod-shaped object 8 can also be absorbed. can.

Furthermore, since the shape of the outer cylinder 1 is relatively simple, shaft machining becomes easy.

Since the structure is such that the rod-shaped object 8 is fed out and used, the rod-shaped object 8 can be used up with almost no waste, and not only can the rod-shaped object 8 be put in and taken out, but also when the rod-shaped object 8 is not set, it does not stain hands or other objects. This has the effect that there are very few things that need to be done.

In addition, the number of parts is small, it can be manufactured at a relatively low cost, and there are fewer failures.
