Description

[Technical field]

[0001] The present invention relates to a structure of a storage container for iron parts and a method for removing iron parts from the storage container. [Background technology]

[0002] Conventionally, there have been storage containers with magnets attached to the bottom surface so that they can be fixed to the iron side of a refrigerator or the like. When removing an iron part such as a thumb tack from the storage container, the lid of the storage container is opened and the storage container is tilted to remove the iron part from inside the storage container to outside the storage container, or the iron part is grasped with fingers. In this case, it is necessary to remove more iron parts than necessary from the storage container, and therefore it is necessary to return the iron parts that are not used to the storage container.

[0003] On the other hand, when trying to remove a thumb tack that has a thin, disk-shaped iron head with an iron needle embedded in the center, the needle tips are stacked in various orientations inside the storage container, making it extremely difficult to grab a thumb tack without pricking your fingers with the needles. Even if you tilt the storage container to remove the thumb tack from the storage container and place it on the desk so that the orientation is more or less uniform, it is difficult to remove it safely as the needles may prick your fingers.

[0004] Here, there are push pins with flat metal heads, but which are made of other materials such as spherical resin, and whose center of gravity is adjusted so that the needle does not point toward the ceiling. Such push pins cannot be used in applications where the unevenness of the pins must not be noticeable after they are inserted. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 3119235 [Patent Document 2] Utility model registration No. 3124233 Summary of the Invention [Problem to be solved by the invention]

[0006] The invention in Patent Document 1 is a storage container that has a sliding magnetic plate and drops iron parts such as thumb tacks by sliding the lid, while the invention in Patent Document 2 is a storage container that lets you hammer thumb tacks into the container without having to pick them up, but both storage containers have complex structures and are difficult to use. [Means for solving the problem]

[0007] In order to solve the above problem, the invention of claim 1 is characterized by comprising a storage container for storing iron parts, at least one side of which is open, and a lid for closing the opening of the storage container and generating an attractive force by magnetic force. It is characterized by: Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example for explaining the present invention, and is not intended to limit the present invention to the embodiment. Furthermore, the present invention can be modified in various ways without departing from the gist of the invention. Furthermore, the same components in each drawing are denoted by the same reference numerals as much as possible, and duplicated explanations are omitted.

[0011] <Embodiment 1> The appearance of a storage container 1 according to a first embodiment of the present invention is shown in Fig. 1, and its cross section is shown in Fig. 2. For simplicity, Fig. 1 and Fig. 2 show a cylindrical storage container 1 that is open at the top, a cylindrical lid 2 that fits into the storage container 1 and is open at the bottom, a magnet 3 that is fixed to the inner surface of the lid 2 using a known technique such as double-sided tape or adhesive, and a thumb tack 4 as the iron part.

[0012] The thumb tacks 4 are stored inside the storage container 1 with their needles randomly stacked. When removing the thumb tacks 4 from the storage container 1, it is nearly impossible to avoid pricking a finger inserted into the storage container 1 with the needles. For this reason, in the past, it was necessary to remove the lid 2 from the storage container 1, tilt the opened storage container 1, place the thumb tacks 4 on a table or desk, carefully remove the overlaps like a domino effect so as not to prick fingers with the needles, and then pick up the thumb tacks with fingers. Furthermore, since more thumb tacks 4 come out of the storage container 1 than the ones you want to use, you need to carefully return the unused thumb tacks 4 to the storage container 1 so that the needles of the thumb tacks 4 do not prick fingers.

[0013] In the storage container 1 according to the first embodiment of the present invention, by simply removing the lid 2 after turning the storage container 1 upside down, the thumb tacks 4 can be attached to the inner surface of the lid 2 with minimal overlap.

[0014] Furthermore, since the thumb tacks 4 are only on the inside surface of the lid 2, cleaning up is easy, and by lightly tapping the top surface of the lid 2 after closing the opening of the storage container 1 with the lid 2, the thumb tacks 4 that have been attracted to the inner surface of the lid 2 by the magnetic force of the magnet 3 can be detached from the lid 2 and returned to the storage container 1 side.

[0015] 3 to 10 show a method for removing thumb tacks 4 from the storage container 1 according to the first embodiment of the present invention. In each state, a) is a front view, and b) is a cross-sectional view.

[0016] As shown in Figure 3, in the initial state where storage container 1 is closed with lid 2, thumb tacks 4 are piled up at the bottom inside storage container 1. The orientation and arrangement of the pins of thumb tacks 4 are random. As shown in Figure 4, storage container 1 is turned over 180 degrees, and then turned over another 180 degrees. By this operation, thumb tacks 4 are uniformly attracted to the surface of magnet 3 fixed to the inside of lid 2, as shown in Figure 5.

[0017] When thumb tack 4 is attracted to magnet 3, the contact state with the magnet is not only with the flat surface of the disk of thumb tack 4, but also with both the edge of the disk and the tip of the needle, and the difference in the contact state between these two creates a large difference in the attractive force.

[0018] Also, due to the magnetic force through the thumbtack 4 that is in direct contact with the magnet 3, some thumbtacks 4 are stacked on top of the thumbtack 4 that is in direct contact and attracted to the magnet 3. Therefore, by appropriately adjusting the magnitude of the magnetic force of the magnet 3, it is possible to realize a situation in which only the former contact state with a large contact area occurs, as shown in Figure 5, and no attraction occurs in the other contact states with a small contact area.

[0019] That is, the disk-shaped flat portion of the thumb tack 4 is attracted to the magnet 3, and the thumb tack 4 is attracted to the magnet 3 with its needle pointing away from the lid 2 and towards the storage container 1. From this state, as shown in Fig. 6, the lid 2 is removed from the storage container 1, and as shown in Fig. 7, by rotating only the lid 2 180 degrees and turning it over, the needle of the thumb tack 4 faces upwards and the multiple thumb tacks 4 are arranged at intervals such that the disks of the thumb tacks 4 do not overlap, so that the thumb tacks 4 can be easily and safely removed one by one.

[0020] As shown in Figure 8, after removing the necessary thumb tacks 4, the lid 2 is turned over to close the storage container 1. This completes the tidying process, eliminating the need to put away unused thumb tacks 4, as was previously necessary. In this state, the unused thumb tacks 4 remain attached to the magnet 3 on the inside of the lid 2.

[0021] This is because the magnetic force of magnet 4 is greater than the gravitational force due to the weight of thumb tack 4, so as shown in Figure 9, by striking lid 2 from above, impacting thumb tack 4 and adding a downward impact force N, a downward force is generated that exceeds the magnetic attraction force, and thumb tack 4 is detached from lid 2 and returned to the storage container 1 side as shown in Figure 10.

[0022] Needless to say, if the lid 2 is not to be used with another storage container 1, or if it is okay for the thumb tack 4 to remain attached to the magnet 3 on the lid 2 when putting it away, there is no need to tap the lid 2.

[0023] As described above, by utilizing the configuration of the storage container 1 and the removal method according to the first embodiment of the present invention, not only is it unnecessary to follow the conventional procedures, but also significant advantages can be obtained, such as being able to remove the containers safely and easily one by one without having to prick your finger with a needle.

[0024] Here, a cylindrical storage container is used, but a rectangular box shape etc. may also be used. Also, although an airtight container is shown in the figure, a fine metal mesh or the like may be used as long as it has a structure capable of storing iron parts.

[0025] Iron parts such as hairpins and clips do not have needles like the thumb tack 4, so they will not prick your fingers, but they can achieve the same effect of making them easier to remove.

[0026] 2 shows an example in which the magnet 3 is fixed to the inside of the lid 2, but it may be fixed to the outside of the lid 2 as long as there is sufficient magnetic force to attract the iron parts to the inside of the lid 2. Furthermore, by making the lid 2 out of a plastic magnet material, the lid 2 itself may have a magnetic force, which naturally provides the same effect.

[0027] In the embodiment, the container has one opening, but it may have multiple openings. For example, the container can be a regular polygon with openings and lids on all sides, and the intersection of the diagonals can be used as the axis of rotation, allowing for continuous removal. The lid can be opened and closed by rotating, and when the lid moves to the upper side, the lid can be flipped over to place the iron parts on the upper surface.

[0028] By using this technology for steel parts such as sheet metal components for industrial products, it is possible to inexpensively pick out individual components from a storage container without using expensive imaging systems.

[0029] <Embodiment 2> Fig. 11a) shows the appearance of a storage container 1 according to embodiment 2 of the present invention, and Fig. 11b) shows its cross section. The structural differences from embodiment 1 are that the lid 2 is made of iron and that a magnet 3 is detachably installed above the lid 2.

[0030] The method of removal is also almost the same as in the first embodiment, with the only difference being the method of returning the thumb tack 4 attracted to the lid 2 to the storage container 1. In the first embodiment, the lid 2 is hit as shown in Fig. 9, but in the second embodiment, the magnet 3, which is removably installed above the lid 2, is removed from the lid 2. By removing the magnet 3 from the lid 2, the attraction force caused by the magnetic force generated on the inside of the lid 2 through the lid 2 disappears, and the thumb tack 4 is returned to the storage container 1.

[0031] As described above, by utilizing the configuration and removal method of the storage container 1 according to embodiment 2 of the present invention, in addition to the effects described in embodiment 1, significant effects can be obtained, such as the fact that there is no need to uniformly install the magnet 3 on the flat portion of the lid 2, and that an existing storage container 1 can be improved into a storage container that is easy to remove.

[0032] Furthermore, in the first and second embodiments, examples have been shown in which permanent magnets are used as magnets, but it goes without saying that the same effect can be obtained by using electromagnets or permanent electromagnets, providing the driving power for driving them with batteries or the like, and providing an ON / OFF switch to control the magnetic attraction force.

[0033] <Embodiment 3> 12 shows a cross section of a storage container 1 according to a third embodiment of the present invention. In the first and second embodiments, the storage container 1 and the lid 2 are fastened by a fitting structure. In this case, repeated fastening and detachment can wear down the sliding parts, and the lid 2 can come off when the container is turned over. The thumb tack 4 has a needle, so there is a risk of injury.

[0034] In this embodiment 3, by providing screw grooves on the storage container 1 and the lid 2, a screw-on type similar to the lid structure of a plastic bottle can be used, allowing for secure closure and reliably preventing the lid 2 from coming off the storage container 1 when inverted.

[0035] As described above, by utilizing the structure of the storage container 1 and the lid 2 according to the third embodiment of the present invention, a significant effect can be obtained, such as ensuring a secure closed state for a long period of time.

[0036] For simplicity, a screw-in type is illustrated here, but it goes without saying that the same effect can be achieved by using a structure for closing the opening using known technology, such as a structure in which the storage container 1 and lid 2 are fastened together with a freely rotatable rotating shaft like a water bottle, and the opening of the storage container 1 is closed with the lid 2 and then locked.
