DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a refill case for storing a refill for a writing instrument such as a refill for a mechanical pencil or a refill for a ballpoint pen.

[0002]

2. Description of the Related Art As an example of a refill case for a mechanical pencil, a refill case as shown in FIG. 4 is widely known. This case has a configuration in which a refill core S 'is accommodated in a refill container 1' having a core outlet 2 'on one side, and a cover 3' is detached from the core outlet 2 '.

[0003] In order to take out the refill core S 'in this prior art, after removing the cover 3', the refill container 1 'must be tilted with the core outlet 2' facing downward. Then, since a large number of extra cores S 'are projected at one time, it is necessary to adjust the number of take-outs by taking out a necessary number of refills.

Further, 'when the facing downward, the lid 3' refill lead container 1 with the lid illustrated state is' open disengaged from, the core outlet 2 'refill lead container 1 refill lead S' is sliding from There are cases.

[0005] Although not shown, there is a configuration in which a refill container having a core outlet on one side is provided with a slide lid, and the slide lid is operated to open and close the core outlet.

In the case of this prior art, the core outlet can be opened and closed by operating the slide lid, and the opening amount of the core outlet can be adjusted. Since the take-out means is the same as the above-mentioned prior art, it is necessary to adjust the number of take-outs, and if the operation of the slide lid is incomplete, the center outlet may remain open. Sometimes, if the refill container is inadvertently turned downward, the refill in the container will slide down.

Therefore, this conventional technique does not solve the problems of the conventional technique at all.

The object of the present invention is to solve such a problem, there is no need to adjust the number of take-outs, and there is no fear of slipping of the refill, and furthermore, the refill container can be oriented in any direction, such as up / down / left / right or inclined. However, the present invention is characterized by a convenient and useful refill case that can reliably take out a small number of refills.

[0009]

In order to achieve the above-mentioned object, the present invention provides means for providing a core outlet at one side of a refill container opposite to one end of a refill core contained in the refill container. Opened,
When a refill container is provided with a resilient lid that is repelled in a direction to always close the refill outlet, and slides in the length direction of the refill core toward the refill outlet, a small number of refills are This means that a centering piece that allows the core to protrude from the core outlet is provided in the extra lead container.

[0010]

[Function] If the centering piece is slid in the length direction of the replacement core toward the center outlet, the resilient cover carried by the centering piece opens the elastic lid at least against the elastic force, and at the same time the center A small number of extra cores carried by Idoma project from the slightly opened core outlet.

[0011] A small number of extra leads protruding from the core outlet are held between the elastic lid and the core outlet and do not slide down.

When a small number of extra cores protruding from the core outlet are taken out, the elastic lid is urged by the elastic force in the direction of closing the core outlet.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of a refill case for a mechanical pencil shown in the figure will be described.

The refill container 1 is formed in a rectangular parallelepiped (illustrated example), another rectangular shape, a cylindrical shape, another elliptical shape, or the like, and defines therein a refill accommodating chamber 5, an elastic lid disposing portion 6, and the like. A vertically long guide hole 7 for a centering piece is formed in a side wall facing the side wall of the elastic lid housing portion.
Is formed by drilling. A vertically long hole 7 drilled in the refill container 1
Is a guide hole for allowing the centering piece 4 to be slidable in the length direction of the refill core S, in the length direction of the refill core container 1 and the length direction of the refill core S accommodated in the container. The centering piece 4 is opened and penetrated through the operation portion side of the centering piece 4 so as to reach the outside of the container, thereby enabling a sliding operation on the centering piece.

The core outlet 2 is provided on one side (left side in FIG. 1) of the refill container facing one end (left end in FIG. 1) of the refill core S accommodated in the refill container 1. , The elastic lid 3 is opened at a position close to the elastic lid arranging portion 6 and is closed at the tip of the elastic lid 3. The core outlet 2 has a holding portion 8 protruding shortly toward the elastic lid placement portion 6 at a lower portion of the edge opposite to the elastic lid placement portion 6 side, and the open elastic lid 3 and the holding portion 8 form a core. Extra lead S protruding from outlet 2
(Represented by phantom lines in FIG. 1) so as to prevent the extra lead from slipping off the extra lead container 1.

The elastic lid 3 is formed by forming a strip-shaped metal piece having a resilient force enough to be pushed open by the replacement core S into a substantially root symbol shape when viewed from the front, and forming a substantially V-shaped bent portion at the base end side when viewed from the front. Along with the elastic lid arranging portion 6, the lateral end portion is arranged at the core outlet 2, and the resilient force acts on the end portion in the V-shaped bent portion direction (the direction of the arrow in FIG. 3) by the V-shaped bent portion. , The core outlet 2 is always closed and assembled. As a material of the elastic lid 3, a synthetic resin (soft) other than the elastic metal piece can be used. When the centering piece 4 is slid toward the centering exit 2, the elastic lid 3 is pushed open by the extra lead S carried by the centering piece, but the elastic force acting in the direction to close the centering outlet 2. Is pushed to the minimum and pushed open
As shown in FIG. 1, when it is pushed, it is pushed open while being in contact with the extra lead S which is gradually extruded from the extra lead container 1. Therefore, the resilient lid 3 does not open so large that many replacement cores S such as five or ten are extruded at a time, and one to three (illustrated examples) carried by the centering piece 4. The minimum opening amount is such that a small number of extra cores S are extruded.

The centering piece 4 has one (in the illustrated example) to three replacement parts 9 for the refill core S formed at one corner of a thin base rod part along the entire length in the longitudinal direction, and on the opposite side to the transfer part side. In the above, a slide operation portion 10 having a length slightly penetrating through the vertically long conductive hole 7 and protruding to the side of the refill core container 1 is configured to extend sideways. The centering piece 4 directs the transfer section 9 to the rear side of the refill container 1,
The sliding operation unit 10 is arranged on the front side of the refill container 1 and set at the position opposite to the core outlet in the refill container 1. Are arranged so as to be transferable to the transfer unit 9, and the slide operation unit 10 is protruded to the side from the vertically long guide hole 7 to be slidably disposed. The centering piece 4 has a stopper 11 extending at the base end (the right end in FIG. 1) of the thin base rod, and the state in which the stopper comes into contact with the inner surface of the outer bottom of the refill container 1 is normal. The state in which the stopper portion 11 is separated from the inner surface of the outer bottom is defined as a use state at the time of extruding the refill core.

In the figure, reference numeral 12 denotes an intermediate bottom for the refill container 5, which is formed at a position near the outer bottom in the refill container 1. Specifically, the bottom side of the transfer portion 9 of the centering piece 4 is lowered toward the outer bottom, and the side wall side where the vertically long guide hole 7 is formed is raised toward one side to form an inclined piece. In a normal state, the extra lead S in the extra lead storage chamber 5 can be automatically transferred to the transfer section 9.

Reference numeral 13 in the drawing denotes a cover attached to the refill container 1, which may be transparent or opaque, but transparent is preferable because the remaining amount of refill can be confirmed. The lid 13 is attached to the refill core container 1 by an appropriate attachment means such as screwing, a covered type, and fixation. The figure shows the fixation means by adhesion.
In the case of a ball-point pen refill case, the length of the above-described embodiment is increased according to the refill.

[0020]

As described above, according to the present invention, a small number of extra cores carried by the centering piece are pushed out from the core outlet and protrude, so that extra cores can be taken out without having to adjust the number of taken out cores.

Since the extra lead protruded from the outlet of the core is held between the elastic lid and the outlet of the core, there is no need to worry about sliding of the extra lead container in any direction.

Further, since a small number of extra cores forcibly carried by the centering piece are taken out from the center outlet, the orientation of the extra core container is smaller than that of the prior art in which the extra core is taken out using its own weight. No matter where you look, you can always take out a few extra cores.

Also, if the extra core is taken out from the core outlet, the elastic lid is urged toward the core outlet by a resilient force to automatically close the core outlet. Can be prevented.
