DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for accommodating tools such as an end mill and a cutter knife blade.

[0002]

2. Description of the Related Art As a case for accommodating an end mill, a knife blade, and the like, a slide-off type case 1 as shown in FIG. 1 is conventionally known. The case 1 includes an elongated main body 2 and a cap 3 that slides and engages with the main body. The cap 3 can be attached to and detached from the upper end protruding portion 2 a of the case main body 2 by using frictional engagement or uneven engagement.

In such a storage case 1, especially when a heavy end mill or the like is stored, the cap 3 is accidentally dropped from the case body 2 due to the weight of the stored material during transportation, and Things may fall.

[0004]

SUMMARY OF THE INVENTION Therefore, a technical problem to be solved by the present invention is to provide a housing case in which the cap does not fall off accidentally and the structure is simple.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to effectively solve the above-mentioned problems.
A tool storage case having the following features is provided.

The tool storage case of the present invention includes an “elongated cylindrical case body with a bottom” and a “cylindrical cap that slides into engagement with an upper end of the case body and closes an upper end opening of the case body”. . In the vicinity of the upper end of the case main body, a long hole extending at a predetermined length in the longitudinal direction of the main body is formed. On the other hand, the cylindrical cap is slidably connected to the case body by using a slide connecting portion of the cylindrical cap.

[0007] The slide connecting portion of the cylindrical cap is composed of a "stem slidably passed through the elongated hole" and a "head wider than the entire width of the elongated hole". Therefore, even when the slide engagement between the case main body and the cap is released, the cap can be kept connected to the case main body by the slide connection portion. As a result, it is possible to prevent the cap from being accidentally dropped from the case body and the contents from falling.

[0008] It is preferable that the head of the slide connecting portion is configured to have a width shorter than the entire length of the elongated hole. In this case, the entire slide connecting portion can pass through the elongated hole, so that the housing case can be easily assembled and the manufacturing cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 2 is an exploded perspective view showing the tool storage case 10 according to the present invention, and FIG. 3 is a perspective view of a main part showing the storage case 10 after assembly. The storage case 10 includes an elongated, bottomed cylindrical case body 20 and a cylindrical cap 30. The cylindrical cap 30 slides and engages with the small-diameter cylindrical protrusion 21 protruding from the upper end of the case main body 21 to close the upper end opening of the case main body.

In the vicinity of the upper end of the case body 20, a case body
An elongated hole 22 extending at a predetermined length in the longitudinal direction of 20 is formed. On the other hand, the cylindrical cap 30 has a slide connecting portion 31 protruding from the peripheral edge thereof. Slide connection part 31
Has a stem 32 slidably passed through the long hole 22 and a long hole
The head 22 is wider than the entire width of the head 22.

The head 33 of the slide connecting portion 31 has a full width W
Since 1 is shorter than the total length L of the long hole 22, it can pass through the long hole 22. However, since the entire width W1 of the head is wider than the entire width W2 of the elongated hole 22, it is possible to effectively prevent the cap 30 from accidentally falling off the case body 20 after assembly, as described later. As can be seen from FIG. 3 which is a perspective view of the main part after assembly, the slide connecting part 31 has a certain degree of flexibility. Further, since the cap 30 is engaged with the cylindrical protrusion 21 on the case body side with a certain frictional force, the total length of the storage case 10 is variable. That is, the same storage case can be generally used for a plurality of types of contents having different lengths.

The cylindrical cap 30 is slidably engaged with the outer peripheral surface of the cylindrical projecting portion 21. However, since the slide connecting portion 31 of the cap 30 is engaged with the long hole 22, the cap 30 is not fitted. It is possible to effectively prevent the case body 20 from being easily detached. FIG. 4 is a schematic diagram for explaining this. In the example of FIG. 4, the tool storage case 10 stores an end mill 40 as a content.

It is assumed that the upper opening of the case body 20 is inadvertently turned downward while the housing case 10 housing the end mill 40 is being transported. In particular, when the weight of the end mill 40 is large, a force acts on the cap 30 in a direction of separating from the case body 20. In the case of the conventional storage case 1 shown in FIG. 1, when such a situation occurs, the cap 3 is easily detached, and as a result, the end mill 40 may fall and be damaged. This is a problem that cannot be underestimated because end mills are expensive. On the other hand, as can be seen from FIG. 4, in the storage case 10 of the present invention, even if the slide engagement between the cap 30 and the protrusion 21 of the case
Since the end mill 40 is connected to the case main body 20 by 31, the end mill 40 can be effectively prevented from falling.

[0014] In addition to the above, the end mill
Even if the cap 30 is intentionally pulled to take out the end cap 40, since the case body 20 and the cap 30 do not separate beyond the relative position shown in FIG. 4, the end mill 40 may fly out of force. Does not happen. As shown in FIG. 5, the end mill 40 can be taken out only by properly positioning the end mill 40 in the case main body and then turning the cap 30 in the direction of arrow A. If the end of the end mill 40 is a cap as shown in FIG.
This is because if it protrudes into the inside of the cap 30, the cap 30 cannot be rotated.

As described above, in the storage case of the present invention, it is possible to effectively prevent the contents such as the end mill 40 from going out of the case regardless of the user's intention.

As can be seen from FIG. 2, in the housing case of the present invention, since both the case body 20 and the cap 30 have a simple structure, the manufacturing cost can be reduced. Also, the assembly of the case body 20 and the cap 30 is very simple.

In the illustrated example, the cap 30 is engaged with the outer peripheral surface of the cylindrical projecting portion 21, and the slide connecting portion 31 is passed through the elongated hole 22 from the outside to the inside of the case body 20. However, the reverse configuration may be adopted. That is, the cap 30 may be engaged with the inner peripheral surface side of the cylindrical projecting portion 21, and the slide connecting portion 31 may be passed through the elongated hole 22 from the inside to the outside of the case body 20. When such a configuration is adopted, the head 33 of the slide connecting portion is
Therefore, it is possible to prevent the head from being damaged by the cutting edge of the end mill as the contents.
