Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a storage device for a fuel compact, and more specifically, when the lid is rotated to seal the opening of an outer container, the rotational force of the lid is This invention relates to a fuel compact storage device that prevents the buffering members in the outer container and the inner container from being deformed and the buffering action of the buffering members is inhibited, and allows the fuel compact to be safely stored in the inner container.

[Prior Art and its Problems] Conventionally, there is a fuel compact storage device that accumulates and stores a plurality of fuel compacts vertically.

This fuel compact storage device stores an inner container in an outer container, cumulatively stores a plurality of fuel compacts in the inner container, and then arranges a first buffer member at the opening of the inner container, Further, a second buffer member is placed on top of the first buffer member, and then a cylindrical lid is attached to the opening of the outer container while rotating so as to cover the second buffer member. The opening of this outer container is sealed with the lid.

However, the fuel compact storage device has the following drawbacks.

In other words, when the lid is attached to the opening of the outer container while applying rotational force to the lid, the first and second buffer members are compressed to some extent by the pressing force of the rotating lid, so that the fuel compact does not wobble. At the same time, the second shock absorbing member also attempts to rotate following the rotation of the lid, causing deformation of the first and second shock absorbing members, allowing the shock absorbing member to properly exert its shock absorbing effect. There is a risk that you will not be able to do so. If the buffering effect of these buffer members is not properly exerted, the fuel compact to be stored cannot be stored safely without fear of damage.

This invention has been made based on the above circumstances.

An object of the present invention is to prevent the shock absorbing member attached to the inner container housed within the outer container from being deformed in any way even when the lid is rotated and attached to the opening of the outer container. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a fuel compact storage device in which the buffering effect of a buffer member on a fuel compact is properly maintained.

[Means for achieving the above object] The outline of this invention for achieving the above object is as follows:
A plurality of inner containers for cumulatively storing fuel compacts are housed in the outer container, sandwiched between upper and lower first buffer members such that the first buffer member protrudes from the upper opening, and a second buffer member is placed on top of the upper first buffer member. A fuel compact storage device in which a lid can be attached to an upper opening of an outer container by rotation while a buffer member is placed thereon,
The present invention is characterized in that a rotational force transmission prevention means for making it impossible to transmit the rotational force of the lid to the first buffering member is interposed between the upper first buffering member and the inner surface of the lid.

The fuel compact storage device in this invention includes:
Since the lid can be attached to the upper opening of the bottomed cylindrical outer container while applying a rotational force to the lid, the lid usually has an end face corresponding to the upper opening and the outer side. and a side surface overlapping the outer peripheral surface of the container. The lid can be attached by, for example, screwing or fitting. In addition, in this fuel compact storage device, a plurality of fuel compacts are cumulatively stored in the outer container, and the first buffer member is arranged above the uppermost fuel compact so as to slightly protrude from the opening of the inner container. A second buffer member is further disposed on the first buffer member.

This invention basically adds a rotational force prevention means to the compact fuel storage device having such a structure.

The rotational force transmitting means may have any configuration as long as it does not transmit the rotational force of the lid when the lid is attached to the opening of the outer container to the first buffer member located at the opening of the inner container. Even if there is, it may be formed of any material.

A more preferable rotational force transmission prevention means is one that can maintain the buffering effect of the first buffer member and the second buffer member without being deformed by the rotational force of the lid.

There are various configurations of such rotational force transmission prevention means, and specifically, for example, between the first buffer member and the second buffer member, and between the second buffer member and the inner surface of the lid. a pair of sheet members with a low coefficient of friction, such as hard synthetic resin plates, arranged between the first buffer member and the second buffer member; It is composed of a plate member and an inclusion that can make point contact with the pair of plate members, such as a ball or an inclusion that can make line contact, such as an O-ring, or between the first buffer member and the second buffer member located above. It can also be constructed of a plate-like member that is interposed in the inner container and fixed to the upper opening of the inner container. Needless to say, various other configurations are possible.

[Function] The fuel compact storage device in this invention has the following features:
The lid is attached to the opening of the outer container while applying rotational force to the lid, and by applying the lid, a pressing force is applied to the first buffer member and the second buffer member, and the fuel compact accumulated in the inner container is loaded. Fix it.

When a rotational force prevention means is interposed between the first buffer member disposed at the opening of the inner container and the second buffer member placed thereon, the rotational force of the lid when the lid is attached is reduced by the first buffer member.
is not transmitted to the damping member and/or the second damping member, and therefore the first damping member and/or the second damping member
The buffer member is not deformed by rotational force, and is compressed only by the pressing force of the lid.
Not only will the stored fuel compact be securely fixed, but the buffer member will also properly exhibit a buffering effect on the fuel compact.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway perspective view showing a first embodiment of the invention.

As shown in FIG. 1, this compact fuel storage device 1 includes a long outer container 3, which is a bottomed cylindrical body that is open at the top and has a male screw 2 formed near the opening, and an inner circumferential surface of the elongated outer container 3. It consists of a circumferential side surface 5 with a female screw 4 formed thereon and a disc-shaped lid 6 corresponding to the opening of the outer container 3. By screwing the female screw 4 into the male screw 2, the outer container 3 is closed. a lid 7 that can be attached to the opening of the outer container 3;
It has a plurality of, for example, six, inner containers 9 each having a bottomed cylindrical shape and opening at the top. The height of this inner container 9 is approximately equal to the height of the outer container 3,
Moreover, the protective member 10 stretched around the inner peripheral surface of the outer container 3 allows the device to be stored in the outer container 3 without directly touching the inner peripheral surface of the outer container 3. Inside this inner container 9, a pair of first buffer members 13 are located on the upper surface of the uppermost fuel compact 12 and the lower surface of the lowermost fuel compact 12, with buffer spacers 11 interposed above and below each fuel compact. A plurality of fuel compacts 12 are accumulated and stored by sandwiching them vertically. The upper first part in the inner container 9
The buffer member 13 is adjusted to a height that slightly protrudes from the opening of the inner container 9, and the upper surface of the first buffer member 13 above is made of synthetic resin, such as acrylic resin, and is made of synthetic resin such as acrylic resin. A lower sheet member 14 having a low coefficient of friction and having a diameter approximately equal to that of the surface is placed.
A cylindrical second buffer member 15 having a diameter substantially equal to the diameter of is disposed, and further, an upper sheet member 16 similar to the lower sheet member 14 is disposed on the upper surface of this second buffer member 15. .

Fuel compact storage device 1 having the configuration shown in Fig. 1
The fuel compact 12 is stored in the following manner.

That is, first, the first buffer member 13 is inserted through the opening of the inner container 9 and placed on the bottom surface thereof. Next, a cylindrical first fuel compact 12 is placed in this inner container 9, and then a buffer spacer 11 is placed on the upper surface of the first fuel compact 12, and a second fuel compact 12 is placed on top of the buffer spacer 11. By repeating this operation, the fuel compacts 12 are accumulated and stored in the inner container 9,
Finally, the first buffer member 13 is placed and housed on the upper surface of the uppermost fuel compact 12 so as to protrude from the opening of the inner container 9.

After the fuel compacts 12 have been accumulated and stored in the six inner containers 9 in this way, the six inner containers 9 are sequentially stored through the opening of the outer container 3 from which the lid 7 has been removed. Incidentally, if there is an inconvenient gap between the six inner containers 9 housed in the outer container 3, the gap may be filled with a protective material such as styrofoam or the like as needed.

After storing the inner container 9 in the outer container 3, the lower sheet member 14 is placed on the first buffer member 13, then the second buffer member 15 is placed on it, and then the upper sheet member 14 is placed on top of the first buffer member 13. Place the sheet member 16. Thereafter, the lid 7 is attached to these upper sheet members 16,
The second buffer member 15 is placed over the lower sheet member 14, and the female screw 4 and male screw 2 are screwed together to form the outer container 3.
Attach the lid 7 to the

At this time, the lid 7 rotates when screwed together, but even if the rotational force of the lid 7 acts on the upper sheet, the upper sheet member 16 has a low coefficient of friction.
This upper sheet member 16 does not rotate following the rotation of the lid 7. Even if this upper sheet rotates slightly following the rotation of the lid 7, the lower surface of this upper sheet member 16 and the upper surface of the second buffer member 15 will slip, and as a result, the second buffer member 15 will rotate due to the rotation of the lid 7. It does not rotate following the .

As the lid 7 is rotated and attached to the opening of the outer container 3, the second buffer member 15 is compressed by the pressing force, and strongly presses against the lower surface of the upper sheet member 16 and the upper surface of the lower sheet member 14. Even if the second buffer member 15 is pressed and starts to rotate, the lower sheet member 14 is interposed on the lower surface of the second buffer member 15.
The rotational force of the lid 7 is not transmitted to the first buffer member 13.

In this way, the rotational force of the lid 7 when the lid 7 is attached is applied to the first buffer member 13 and the second buffer member 15.
Therefore, neither the first buffer member 13 nor the second buffer member 15 is deformed due to rotation, and continues to maintain its buffering properties.

As a result, when the lid 7 is screwed onto the opening of the outer container 3, the fuel compact 12 is moved by the upper and lower first and second buffer members 13 and 15, as shown in FIG. The first buffer member 13 and the second buffer member 1 are protected against impacts from above and below and are compressed by attaching the lid 7.
5, it is firmly fixed in the inner container 9.

In this embodiment, since the protective member 10 is also extended around the inner peripheral surface of the outer container 3, the fuel compact 12 is sufficiently protected against impacts from the lateral direction.

Next, a second embodiment of the present invention is shown in FIG.

FIG. 3 is a partially cutaway vertical cross-sectional view showing the main parts of the present invention in another embodiment of the present invention.

As shown in FIG. 3, the rotational force transmission prevention means in this embodiment includes a plate member 17, a substrate 18 provided on the lower surface of the second buffer member 15, and a plate member 17.
and a ball 19 interposed between the substrate 18 and the substrate 18.

This plate member 17 is placed on the upper surface of the first buffer member 13 placed on the upper surface of the uppermost fuel compact 12 among the cumulatively stored fuel compacts 12 so as to protrude upward from the opening of the inner container 9. be done. The plate member 17 is made of synthetic resin, such as acrylic resin, and is molded into a disk shape with a diameter approximately equal to the inner peripheral surface of the outer container 3, and has a ring-shaped groove 20 on its upper surface. established,
A plurality of balls 19 are rotatably housed in this groove 20.

The substrate 18 is provided on the bottom surface of the second buffer member 15 and is placed on the top surface of the plate member 17 with the ball 19 interposed therebetween.

This substrate 18 and this plate member 17 have a ball 19 interposed between them that can make point contact, and since the plate member 17 is arranged on the upper surface of the first buffer member 13, the plate member 17 can be freely moved. The substrate 18 can now move freely.

When the rotational force transmission prevention means is configured in this way,
When attaching the lid 7 to the outer container 3, even if the rotational force of the lid 7 is transmitted to the second buffer member 15, the second buffer member 15 will naturally follow the rotation of the lid 7 and rotate. The buffer member 15 is not deformed by rotation, and even if the second buffer member 15 rotates, the base plate 18 and the plate member 17 are in point contact with each other at the intervening ball 19, so that the first buffer member 15 is not deformed due to rotation.
No rotational force is applied to the buffer member 14, and the first buffer member 14 is not deformed.

In this embodiment, the other components other than the rotational force transmission prevention means are the same as those of the first embodiment, so detailed explanation thereof will be omitted.

Further, as the rotational force transmission prevention means in the third embodiment, an O-ring may be placed in the groove 20 instead of the ball 19.

In this case, the O-ring may be made of a hard material such as Teflon, which has a small coefficient of friction with the plate member. Furthermore, when using an O-ring that is made of rubber or the like and has a large coefficient of friction with the plate-like member, a lubricant such as silicone grease can be applied to the O-ring.

In this case as well, the same effects as in the second embodiment can be achieved.

A fourth embodiment of the present invention is shown in FIG.

As shown in FIG. 4, the rotational force transmission prevention means in this embodiment is a hard plate-like member having an outer diameter approximately the same as the diameter of the inner peripheral surface of the outer container 3 and having a bolt insertion hole in the center. 21 and is placed on the upper surface of the first buffer member 13 placed in the opening of the inner container 9. Then, a locking plate 22 having substantially the same shape as the plate-like member 21 is interposed between the bottom surfaces of the plurality of inner containers 9 housed in the outer container 3 and the bottom surface protection member 8A, and then this locking plate A leg-long bolt 23 is inserted into the bolt insertion hole in the center of the bolt 22, and the head 23A of this bolt 23 is inserted into the locking plate 2.
2 and the bolt 2 of the plate member 21
3. Insert the tip of this leg-long bolt 23 into the insertion hole, then screw the nut 23B onto this bolt 23, and tighten the nut 23B to press this plate-like member 21 against the opening of the inner container 9 and fix it. do.

Note that the bottom protection member 8A and the second buffer member 1
5A is the head 23A of the bolt 23, the bolt 2
In order to arrange the tip of No. 3 and the nut 23B, it is preferable to form a donut disk shape with a hole of an appropriate size in the center. In addition, the rotational force transmission prevention means, the bottom protection member 8A and the second
The other members except the buffer member 15A are the same as in the first embodiment. That is, the upper sheet member 16 is arranged on the upper surface of the second buffer member 15A. Therefore, detailed explanation thereof will be omitted. Further, the plate member 21 is used by providing a groove 20 on its upper surface, as in the case of the plate member 17, and arranging the ball 19, the base 18, and the second buffer member 15 in this order as shown in FIG. You can also do that. In this case, the same effect as in the third embodiment is exhibited.

Also in this fourth embodiment, when the lid 7 is attached to the outer container 3, even if the lid 7 is rotated, the rotational force of the lid 7 is not transmitted to the first buffer member 13; No deformation due to rotational force.

[Effects of the Invention] According to the present invention, since the rotational force transmission prevention means is provided, when the lid is rotated and attached to the opening of the outer container, the deformation of the buffer member due to the rotational force of the lid can be effectively prevented. It can be prevented. Therefore, the fuel compact storage device of the present invention can safely protect the fuel compact from external impacts.
