An embodiment of the invention is shown in FIGS. 1 to 8.

That is, this electric shaver case has a flat box shape consisting of an upper case 1 and a lower case 2, and the peripheral edge of the case 1.2, except for one end 3, is tapered 4 so that it can be stored in a handle or a travel bag, etc. One end 3 is provided with a rib 3b on the periphery of the surface 3a to sink the surface 3a to form a recess, and a push operation part (PUSH) 5 for opening and closing is provided flush with the surface 3a. There is.

Further, on the lower surface of the lower case 2, as shown in FIG. 2, a supporting plate 6 is formed in a bulging manner, and small hemispherical feet I are formed at the four corners of the supporting plate 6.

In this way, the appearance of the case resembles that of a leather case.

The upper case 1 is formed by molding a resin material, and has a top plate 8.
Except for the one end 3 side, a taper 4 is formed in a U-shape when viewed from above, and at the same time, a taper 4' that sinks inward appears on the back surface in accordance with the shape.

A cushion plate 9 is attached to the central portion of the back surface of the top plate 8, that is, the portion surrounded by the taper 4'.

The lock pawl 10 is extended outward from the central edge of the concave surface 33' of the one end 3 of the upper case 1, and grooves 11° 11' are formed inward along both sides of the lock pawl 10. is made to have flexure due to resin elasticity, and a push operation part 5 is formed in the middle part thereof.

At the opposite end 12 facing the one end 3 of the upper case 1, a hinge plate 13 corresponding to the height of the lower case 2 extends outward, and a cylindrical shaft 14 extends inward at its tip. , and an opening regulating surface 15 is formed on the outer surface thereof.

The lower case 2 is also resin-molded in the same way as the upper case 1, and has a U-shaped taper 4'' formed on the inside of the bottom plate 16 that corresponds to the taper 4 of the lower case 2, and a support plate 6 formed with a U-shaped taper 4'' that corresponds to the taper 4 of the lower case 2. A corresponding recess 17 is formed in the central part surrounded by the taper 4'', and a notch 18 into which the push operation part 5 of the upper case 1 enters is formed at one end 3, and the inside below the notch 18 is formed. A locking recess 19 into which the lock claw 10 engages is formed as shown in FIG.

Further, the opposite end 20 opposite to this one end 3 is the upper case 1.
A recess 21 that is recessed inward of the case to accommodate the hinge plate 13 of the
The edge 23 of the bottom bottom 22 serves as a stopper 23 in the open state (FIG. 7), and the bottom plate 1 is formed at both ends of the end 20.
Pin insertion hole 2 penetrating from connecting corner 24 of No. 6 to recess 21
5 is formed.

Therefore, when assembling the upper case 1 and the lower case 2, the cylindrical shaft 14 of the upper case 1 is located in the recess 21 of the lower case 2 and aligned with the insertion hole 25, and the rotating shaft 26 is aligned with the insertion hole 25 and the cylindrical shaft 14.
When the lid is closed, the push operation part 5 fits into the notch 18, and the lock pawl 10 locks into the locking recess 19 by elastic resin, and when the lid is opened, the push operation part 5 fits into the notch 18, and when the lid is opened, the push operation part 5 fits into the notch 18, and when the lid is opened, The maximum opening amount is regulated by the collision between the stopper 23 and the regulating surface 15.

On the other hand, a support base 11 for positioning an electric shaver 27 is attached to a recess 17 in the center of the bottom plate of the lower case 2.

This support stand 11 is made of an elastic material such as rubber, and corresponds to the shape of the T-shaped reciprocating electric shaver to be positioned. A U-shaped rib 29 for positioning the rear end 27b of the electric razor 27, and a mounting rib 31 for the hair removal brush 30 near the rear end of the negative side. Positioning ribs 34 for the plug 33 of the power cord 32 (including a charging/AC adapter) are integrally formed on the other side.

The brush mounting rib 31 is made up of a box frame portion 31a that surrounds and supports one side of the handle portion 30a of the brush 30, and a pair of side portions 31b and 31c that hold and prevent the brush from falling down.

Further, the plug positioning rib 34 includes a pair of side portions 34a and 34b that sandwich the rear side of the main body of the plug 33, and a plug blade 33.
A protrusion 34 that locks onto the front end surface 33b that is the protruding side of a.
It consists of c.

FIG. 4 shows the electric shaver 27 in its housed state. The electric shaver 27 is positioned when the head 27a is housed in the column part 2B and the rear end 27b is housed in the U-shaped rib 29, and the brush 30 is positioned when it is housed in the brush mounting rib 31. Furthermore, the power cord 32 accommodates the plug 33 in the plug positioning rib 34 and makes the curled part 32a run along the U-shaped taper 4'', and the inside thereof is connected to the outer side part 34b of the plug positioning rib 34 and the pillar part 28. Outer peripheral surface and brush mounting rib 31
They are positioned in a U-shape by being supported by the outer side portions 31b of each.

That is, the cord storage portion 35 is formed by the inner surface of the tapered 4τ lower case 2 and the rib group of the support base 11.

When the electric shaver 27 and the like are stored and the upper case 1 is closed, the electric shaver 27 is suppressed and fixed by the cushion plate 9 of the upper case 1.

Further, as shown in FIG. 6, a U-shaped rib 29 is located behind the lock pawl 10 that is locked in the locking recess 19, so that it serves as a support to prevent damage when excessive external force is applied to the push operation part 5. .

Because of this structure, this electric shaver case has the following features.

That is, (1) the electric shaver 27 is located in the center of the lower case 2, the cord 32 is stored around it in a U-shape, and the upper case 1 corresponds to the U-shaped portion of the cord storage section 35; Since each side of the lower case 2 is formed into a tapered shape, by closing both cases 1 and 2, the case 1,
The volume of the cord storage section 35 of No. 2 can be reduced, unnecessary wobbling of the cord 32 can be prevented, and the entire case can be made smaller.

Note that the taper 4' of the upper case 1 may be omitted.

(2) A support base 1 made of an elastic body is located approximately at the center of the lower case 2.
1, an electric shaver 27 is placed here, and ribs 28, 29, 31,
34, and a space is provided between the ribs 28゜29.31, 34 and the inner surface of the case in whole or in part (for example, in a U-shape), and the cord 32 is disposed in this space. A cord storage portion 35 is formed between the ribs 11 and the inner surface of the case, so that a cord-dedicated holding member is not required, and the case structure is simplified.

(3) If the rib 29 of the support base 11 is located behind the lock claw 10 located on the lower case 2 in the closed state, and the push operation part 5 for unlocking is pushed in more than necessary, the lock claw 1
0 is placed so that it touches the rib 29, the push operation part 5
The lock claw 10 prevents unnecessary pushing and external force impact.
damage can be prevented.

(4) It also serves as a holding rib for the cleaning brush mounting rib 31.

Since the outer side part 31b also served as the positioning of the cord 32,
The support stand 11 can serve both the function of positioning the cord and holding the brush, and the number of ribs can be reduced.

(5) As shown in Fig. 8a, the hinge rotation shafts 26 of the upper case 1 and lower case 2 are located at the lower part of the side wall of the lower case 2, so they are different from the case where they are located at the upper part as shown in Fig. 8. In comparison, since the center of gravity of the upper case 1 is located at the lower part when the case is opened, stability is increased and the case as a whole is less likely to fall forward.

(6) Since the rotary shaft 26 is inserted from the side surface of the lower case 1 and supported by a hinge, assembly is easy and the holding strength is high.

(7) Since the taper 4 is provided at the bottom of the lower case 2 on the hinge side as shown in Fig. 8C, the entire case is opened when the case is opened. When it falls down, the primary inclination angles α1 and α2 become αl<α2, so it is easy to return (P is the grounding point).

(8) Since a taper 4 is formed on the outer periphery of the cases 1 and 2, and only one end 3 is flat and the push operation part 5 is provided as a recess, the rib 3b makes it easy to put your finger on it, and only the operation part 5 is flat. It is easy to use both in appearance and feel, and the operation section is easy to understand.

Further, even if the case is put into a bag or the like, external force is not easily applied to the operation part 5, so that it can be prevented from being opened unexpectedly.

As described above, in the electrical appliance case of the present invention, the cord storage part is formed all around or part of the inner circumferential surface of the lower case, and the bottom surface is tapered, so that the cord can be easily stored and stored. At best, it has the effect of preventing rattling.
