Description

[Detailed description of the invention] Purpose of the invention (industrial field of application) This invention relates to a cutlery with a storage case, especially a scalpel used in surgery and dissection.

(Prior Art) Conventionally, there are disposable scalpels with storage cases used for surgeries and dissections. Therefore, it is desirable to manufacture such a scalpel at low cost by minimizing the material costs required for its manufacture. However, conventional female storage cases are sheath-shaped with a pair of side plates, so manufacturing the storage case requires a lot of material costs, making it impossible to manufacture the case at a low cost. As a result, the entire knife could not be manufactured at low cost. Furthermore, when the case is made of plastic, it is difficult to mold it.

(Problem to be solved by the invention) Therefore, in this invention, the storage case for storing the body of a knife such as a scalpel is formed in a sheath shape, and the material cost required for manufacturing it is high, making it impossible to manufacture it at a low cost. ,
This is intended to solve the problem that the entire cutter cannot be manufactured at a low cost, and furthermore, that it is difficult to mold the case when it is made of plastic.

Structure of the invention (means to solve the problem) In order to solve the above problems, this invention
It consists of a knife main body M and a storage case 8, which has a storage recess 9 on the side surface of one side plate 8a in which the body 4 of the cutler main body M can be stored. is provided with a retaining protrusion 6 consisting of a neck portion 6b having a head portion 6a at its tip, and an engagement hole 11a into which the head portion 6a is inserted.
and a locking hole 11b into which the neck portion 6b is locked.

(Function) After storing the body 4 of the cutler body M in the storage recess 9 of the storage case 8, to lock both M and 8, the head 6a is inserted into the insertion hole 11a, and the retaining protrusion is inserted. The locking hole 1 of the retaining hole 11 is moved by moving the neck 6b of 6.
Put it in 1b. Conversely, from the knife body M to the storage case 8
In order to remove it, it is sufficient to release the lock between the neck portion 6b and the locking hole 11b.

(Embodiment) Hereinafter, an embodiment of the present invention in a scalpel with a storage case for surgery will be explained with reference to the drawings. 1 is a plastic handle of the scalpel body M, 2 is the front end of the handle 1 on both sides. It is a grip portion formed on a surface, and is formed in an uneven shape. Reference numeral 3 denotes a plate-shaped plastic holder extending further forward from the front end of the handle 1, and the thickness of the plate is approximately half that of the handle 1. 4 is a female body fixed to the inner surface of the holder 3 (the left side in FIG. 4) by a protrusion 5 that is integrated with the holder 3, and its front end protrudes forward from the holder 3. . Further, the blade 4a of the body 4 protrudes further downward from the lower edge of the holder 3.

In particular, as shown in FIGS. 3 and 4, reference numeral 6 is a retaining protrusion that protrudes from the rear end of the outer surface of the holder 3, and is connected to a circular head 6a and a base end of the head 6a. It consists of a neck portion 6b.

Reference numeral 8 denotes a storage case for storing the body 4 of the female main body M, and is composed of one side plate 8a and a storage recess 9 formed on the inner surface of the side plate 8a. The entire area is open. Note that the vertical width of the storage recess 9 is wider than the width of the body 4.

In particular, as shown in FIG. 1, reference numeral 10 denotes an insertion recess provided in the back half of the storage recess 9, into which the holder 3 is inserted when the storage case 8 is attached to the female main body M. I'm starting to get it.

Reference numeral 11 denotes a retaining hole provided at the rear end of the insertion recess 10, into which the retaining protrusion 6 on the outside of the holder 3 can be removably engaged. The retaining hole 11 is the head 6 of the retaining protrusion 6.
The insertion hole 11a into which a is inserted, and the insertion hole 11a
The locking hole 11b extends forward from the locking hole 11b and has a narrower vertical width than the locking hole 11b. Note that both upper and lower edges of the locking hole 11b are formed to have a thin plate thickness so that the neck portion 6b of the retaining projection 6 can move. Reference numeral 12 denotes an engaging protrusion protruding inside the insertion recess 10 at the rear of the retaining hole 11, and when the scalpel main body M is stored in the storage case 8, the front end of one gripping part 2 of the handle 1 By being engaged in the engagement recess 2a, the locking state between the scalpel main body M and the storage case 8 can be made more secure.

Reference numeral 13 denotes an uneven finger rest portion integrally formed at the rear end of the storage case 8 on the back side.

Now, when storing the body 4 of the scalpel main body M in the storage case 8 in the scalpel configured as described above, first, as shown in FIG. It engages in the engagement hole 11a of the retaining hole 11 of the case 8. In this way, the body 4 is positioned in the storage recess 9, and the holder 3 of the scalpel main body M is inserted into the insertion recess 10 of the storage case 8. Next, when the scalpel main body M is moved forward with respect to the storage case 8, the neck 6b of the retaining projection 6 of the holder 3 locks in the retaining hole 11, as shown in FIGS. Enter into the hole 11b. Then, the head 6a of the retaining projection 6 is latched to both upper and lower outer edges of the locking hole 11b.

In this case, the holder 3 moves forward within the insertion recess 10, and the body 4 similarly moves forward within the storage recess 9. Then, the female body M is locked in the storage case 8, and the female body 4 is stored in the storage case 8 in a locked state. Furthermore, in the state in which the female body M is housed in the storage case 8 in this way, in addition to the engagement between the retaining protrusion 6 and the retaining hole 11,
The engagement protrusion 12 at the rear end of the insertion recess 10 is engaged into the insertion recess 2a of the female main body M, thereby reinforcing the locked state. Therefore, when the body 4 is stored in the storage case 8, the storage case 8 will not come off naturally from the scalpel main body M.

When storing the body 4 of the scalpel body M in the storage case 8, the body 4 is placed by aligning the holder 3 of the scalpel body M along the insertion recess 10 of the storage case 8.
It is possible to prevent the blade edge 4a from coming into contact with the edge 9a of the storage recess 9 and being damaged.

Further, when the body 4 of the scalpel main body M is housed in the storage recess 9 of the storage case 8, the back side of the body 4 comes into contact with the back of the storage recess 9 as shown in FIG.
The blade 4a is stored in the storage recess 9 in a state separated from the ventral edge 9a. Therefore, the blade 4a of the body 4 will not come into contact with the edge 9a of the storage recess 9 and be damaged.

When removing the storage case 8 from the scalpel main body M, hold the handle 1 and place your thumb on the storage case 8.
Place the finger on the finger rest 13 on the back side, and use this finger to push the entire storage case 8 forward. In this way, the entire retaining hole 11 of the storage case 8 moves forward, and as a result, the retaining protrusion 6 of the holder 3 moves relatively backward within the retaining hole 11. Then, the engagement hole 11a of the retaining hole 11 and the head 6a of the retaining protrusion 6 correspond, and the engagement between the retaining protrusion 6 and the retaining hole 11 is released. Also, storage case 8
When the lock moves forward, at the same time as the lock is released,
The engagement recess 12 at the rear end of the insertion recess 10 is disengaged from the engagement recess 2a of the female main body M, and the engagement between the two is released. Therefore, the storage case 8 can be removed from the scalpel main body M and used.

In addition, after using the scalpel main body M, it is sufficient to store the scalpel main body M in the storage case 8 in the same manner as described above and throw it away in that state.

In this way, the storage case 8 of this embodiment is formed of a single side plate 8a and is not shaped like a sheath, so it can be manufactured at low cost without requiring material costs. Therefore, the entire blade can be manufactured at low cost and is suitable as a disposable item. Furthermore, the storage case 8 is very easy to mold.

(Another Embodiment) The present invention is not limited to the above-mentioned embodiment, and any changes as described below can be made without departing from the spirit of the invention.

For example, the retaining protrusion 6 may be provided on the side or back side of the handle 1. When provided on the back side, the retaining hole 11 is also provided on the back side of the storage case 8 correspondingly.

Further, in the embodiment described above, the finger rest part 13 is formed at the rear end of the back side of the storage case 8, but instead of this, circular finger rest recesses may be formed on both sides of the front end of the storage case 8. In this case, place two fingers on both recesses and pull the storage case 8 forward to remove the storage case 8 from the scalpel main body M.

Furthermore, if the storage recess 9 of the storage case 8 is recessed to the same depth as the insertion recess 10, the insertion recess 10 does not necessarily need to be provided.

The retaining protrusion 6 may be formed on the storage case 8, and the retaining hole 11 may be formed on the holder 3 of the female body M.

Note that the present invention is applicable not only to scalpels but also to other cutlery such as cutting knives, fruit knives, and scissors.

Effects of the invention As detailed above, the present invention not only reduces the cost of materials required to manufacture the storage case that houses the cutlery, making it possible to manufacture the entire cutlery at a lower cost, but also allows the storage case to be made of plastic. In this case, it is easy to mold, and furthermore, the blade body can be stored in the storage case without the blade body falling out of the storage case.
