The present invention relates to a box-shaped safety cap for detachably locking a handle portion of a T-shaped razor and accommodating a head portion of the T-shaped razor. [0002] Since the sharpness of the blade of a T-shaped razor is sharp and may cause a wound accident, a safety cap is attached to the head of the T-shaped razor. If the safety cap attached to the head unit is simply detached from the head unit, the safety cannot be sufficiently maintained, so that the safety cap is locked after the attachment. Various types of safety caps mounted on such a T-shaped razor have been conventionally provided.
The safety cap 70 shown in (a) covers the blade 75 by covering the head portion 76 of the T-shaped razor 77 from above and covers the protrusion 71 provided inside the rear part of the safety cap 70 with the head portion 76.
Is locked to a ridge 78 protruding from the rear side. The safety cap 80 shown in FIG. 8B is inserted into the head portion 86 of the T-shaped razor 87 from the lateral direction, and the flat back side of the head portion 86 is formed by a projection 81 projecting from the bottom of the safety cap 80. Is to be locked. [0003] However, any of the conventional safety caps 70 and 80 are T-shaped razors 7.
Since the safety cap 70 is locked at the rear side of the head section 76, the ridge 78 is provided at least on the rear side of the head section 76. And the head 86
In the safety cap 80 which is inserted from the side and is locked on the back surface side of the head portion 86, the back surface side of the head portion 86 must be made flat. Therefore, the degree of freedom of the configuration of the head portion of the T-shaped razor is limited. Also, since the conventional safety cap had to be mounted and removed from the top and sideways of the T-shaped razor head, there is a risk that it will not be able to be mounted especially if the mounting is done in a hurry, and the finger may be cut.・ It was necessary to pay close attention to removal. Accordingly, the present invention has been made to solve the problems of the conventional safety cap of a T-shaped razor, and a T-shaped razor having various types of heads which can be freely configured with a head portion. It is an object of the present invention to provide a T-shaped razor box-shaped safety cap having a simple configuration that can be widely applied to a T-shaped razor and that securely and removably locks the T-shaped razor. [0005] In order to solve the above-mentioned problems, the invention of claim 1 is characterized in that a T-shaped razor and a safety razor are provided.

Is configured. The center of the bottom plate 20 in the longitudinal direction is T
First for detachably locking the handle 62 of the character-shaped razor 60
A notch 21 is formed. The first notch 21 has a rectangular shape and has bulges 25 on both sides of a back portion, and opens to the opening side. The handle portion 62 of a T-shaped razor 60 having a substantially triangular cross section shown in FIG. 5 is inserted into the first notch 21. The width of the first notch 21 is set substantially the same as the length of the base of the substantially triangular shape of the handle 62. The depth of the first notch 21 is set to be larger than the height of the substantially triangular shape of the handle 62. Projections 23, 23 each forming an arc shape in a plan view are protrudingly provided at the end portions of both side walls of the first notch 21. Further, rectangular second notches 22 are formed on both sides of the first notch 21 formed in the bottom plate portion 20, respectively. The width of the second notches 22, 22 is smaller than the width of the first notch 21, and the depth is set similarly to the first notch 21. By forming the second notches 22 on both sides of the first notch 21, the projections 23 are provided with elasticity. That is, by forming the second notches 22 on both sides of the first notch 21, the first notch 21 is formed.
And the second cutouts 22, 22, two pieces 24, 24 are respectively formed, and these pieces 24, 24 can be bent in the left and right directions with the base end as a fulcrum, as shown by arrows in FIG. Since the projections 2 can be formed,
Elasticity is given to 3,23. Next, a method of attaching and detaching the safety cap 50 configured as described above to and from the T-shaped razor 60 will be described. To attach the safety cap 50 to the T-shaped razor 60, hold the handle 62 with one hand and use the other hand to hold the side plates 30, 30 of the safety cap 50 with the other hand.

At the same time as the bottom of the handle 62 passes through the projections 23 and 23 and the handle 62 itself is inserted into the first notch 21, the head 61 is fully secured from the front as shown in FIGS. It is inserted and accommodated in the cap 50. The first notch 21 has bulges 25, 25 on both sides of the back, and is fixed because the inserted handle 62 is fixed by the protrusions 23, 23 and the bulges 25, 25. The T-shaped razor 60 is securely fixed to the safety cap 50. As described above, the safety cap 50 is configured to lock the handle 62 of the T-shaped razor 60 and to house the head 61 in the box-shaped safety cap 50. Since there is no restriction by the locking means 50, the head 61
Can be configured in any manner. The handle portion 62 of the T-shaped razor 60 once housed in the safety cap 50 has the projections 23, 23 unless the safety cap 50 and the T-shaped razor 60 are relatively moved by applying force. Since the safety cap 50 cannot be passed through and is locked in the first notch 21 and the safety cap 50 does not easily come off the T-shaped razor 60, the injury by the blade 63 can be prevented and the safety can be maintained. On the other hand, in order to remove the safety cap 50 from the T-shaped razor 60, the safety cap 50 and the T-shaped razor 60 may be moved relative to each other so as to separate from each other while slightly applying a force. At this time, the projections 23 are bent in the left-right direction, so that the handle 62 is opened from the inside of the first notch 21. The T-shaped razor box-shaped safety cap of the present invention can be embodied by changing various forms.
(1) The projections may be provided near the center of both side walls of the first notch. With this configuration, a T-shaped razor having a handle portion having a square cross section can be locked while holding the handle portion by the restoring force of the elastic projection. Since the present invention is configured as described above, the following effects can be obtained. In the safety cap according to the first aspect of the present invention, the handle of the T-shaped razor is detachably locked, and the head of the T-shaped razor is housed in the box-shaped safety cap. It can be freely configured in terms of function, and it is not necessary to configure a safety cap corresponding to the configuration of the head part. In combination with this, it is economical. Further, the safety cap according to the first aspect of the present invention is excellent in safety, and can be securely attached to and detached from the T-shaped razor.
