A push-up plate 9 is provided in the case body 2 as in the prior invention. The push-up plate 9 is urged upward by a compression coil spring 10 disposed between the push-up plate 9 and the bottom surface of the case body 2.

[0009] Opposite inner surfaces 2 of the case body 2 are provided.
In b and 2b, push-up plate locking means 11 for locking a push-up plate which is urged to go upward is provided. The push-up plate locking means 11 is connected to the case body 2.
2 and a plurality of claws 13 housed in the space and engaged with the push-up plate 9 (see FIG. 1). It is constituted by a lock member 14 and an operation plate 15 that operates the lock member 14 in conjunction with the opening operation of the lid 3. The cover 12 has a U-shaped horizontal section. A rectangular hole 16 is formed in the front plate 12a located inside the case body 2. The cover 12 has a top plate 12b at the top, and a hole 17 is also formed in the top plate 12b. Further, the cover 12 is
A boss 18 is provided on the lower back surface of the lower portion a. Lock member 14
Are formed side by side in the vertical direction on the surface of the plate body 14a. Further, strips 19 constituting a leaf spring are provided on both sides in the vertical direction of the plate body 14a so as to extend in the back direction. The operating plate 15 has a hole 20 in the center and a top plate 15a extending in the back direction at the upper part.

Then, as shown in FIG. 3A, the cover 12 is fixed to the case body 2 by screws 21, and the operation plate 15 is attached to the back surface of the front plate 12a of the cover 12 so as to be movable in the vertical direction. The lock member 14 is attached to the back surface of the operation plate 15 with the claw 13 facing the hole 20 of the operation plate 15 and the hole 16 of the cover 12. And in the push-up plate locking means 11 assembled in this way,
The lock member 14 is constantly urged inward by the strip 19. The lid 3 is provided with a heater section 22 (see FIG. 1) having a heater on the inner lower surface, a projection 23 (see FIG. 1) protruding downward on both sides, and a handle 24 (FIG. 1) on the upper surface. Reference).

The inner lid 4 is formed of a thin plate-like elastic resin or the like, and has arc-shaped holes 25a and 25 formed on both sides.
a and a slit 25 connecting the holes 25a, 25a
b form an H-shaped tissue take-out port 25, and a circular hole 25c is formed in the middle of the slit 25b. Holes 26 are formed on both side edges of the inner lid 4. With these configurations,
It can be displaced in the wet tissue take-out direction. Therefore, when the lid 3 is closed, the inner lid 4 contacts the lower surface of the lid 3 to transmit heat from the heater section 22 to the wet tissue pack A, and when the lid 3 is opened, the push-up plate locking means 11 according to the present invention causes The movement of the push-up plate is locked, and the take-out opening divided into two of the inner lid 4 is elastically bent, so that when taking out the wet tissue, the take-out opening bends elastically, and a slight Since a gap is generated, the wet tissue can be easily taken out. In addition, the inner lid 4 is not limited to such an H-shaped tissue take-out port, and may be of any material and configuration that can be displaced in the take-out direction of the wet tissue.

The lid 3 and the inner lid 4 configured as described above.
Are attached to the case body 2 by the hinges 5 and 6 so as to be freely opened and closed. After the wet tissue pack A is placed on the push-up plate 9 of the case body 2, the inner lid 4 is closed. Then, the wet tissue pack A is urged upward by the spring 10 via the push-up plate 9, and the upper surface thereof is brought into contact with the inner lid 4. In the non-use mode of the wet tissue a, the lid 3 is closed. Then, as shown in FIG. 3A, the projection 23 of the lid 3 is inserted into the cover 12 through the hole 26 of the inner lid 4 and the hole 17 of the cover 12 constituting the locking means 11. As shown in FIG. 3A, the projection operates to push down the operation plate 15, so that when the operation plate 15 is pushed down, the claw 1 of the lock member 14 is located at the upper edge of the hole 20.
3, the lock member 14 is retracted (toward the side wall of the case body). Therefore, the claw 13 of the lock member 14 is retracted from the front surface of the cover 12 to the inside, and the movement of the push-up plate 9 is made free. Therefore, the wet tissue pack A is urged upward by the spring 10 via the push-up plate 9, and the upper surface thereof comes into contact with the inner lid 4. At this time, although the inner cover 4 is interposed in the middle, the heating is efficiently performed by positioning the wet tissue above the wet tissue pack A to be taken out at the time of use near the heater section 22 in the cover 3 first. be able to.

Next, when the lid 3 is opened in order to use the wet tissue a, as shown in FIG.
The projection 23 of the lid 3 is formed by the hole 26 of the inner lid 4 and the locking means 11.
Escapes from the hole 17 of the cover 12 constituting. Then
The lock member 14 protrudes upward by a distance t1 into the case body 2 while pushing up the operating plate 15 that has pushed the lock member 14 by the urging force of the strip 19, and is located directly above the edge of the push-up plate 9. The engaging claw 13 engages with the push-up plate 9. Therefore, the push-up plate 9 is restrained at that position against the urging force of the spring 10, and does not move upward any further. Therefore,
When the wet tissue a is taken out of the wet tissue pack A in this restrained state, as shown in FIG.
Since the edge of the tissue take-out opening 25 of the inner lid 4 is bent upward together with the wet tissue a, a slight gap is formed in the vertical direction, so that the wet tissue a can be easily taken out of the case body 2. in this way,
In the first embodiment, in the locking means 11, the claw 13 of the lock member 14 is formed with an inclined surface on the upper surface, and the operating member 15 is pressed against the inclined surface, thereby operating the lock member 14 and By engaging the lower surface (horizontal surface) of the push-up plate 9 with the push-up plate 9, the push-up plate 9 is prevented from moving upward. Since a slight gap is formed, the wet tissue a can be easily taken out of the case main body 2.

As a modification of the first embodiment, there is a wet tissue warmer shown in FIG. As shown in the drawing, an inclined surface is formed on the lower surface of the claw 13, and as shown in FIG. 5B, when the claw 13 contacts the push-up plate 9, the push-up plate 9 is I try to lower. Further, in FIG. 6A, a friction plate 27 is provided in place of the claws 13 except for the claws (the uppermost and lowermost claws in the figure) 13 with which the operation plate 15 contacts,
As shown in FIG. 6B, the friction plate 27 may be pressed against the push-up plate 9 to prevent the push-up plate 9 from moving upward.

In the first embodiment and the modification,
The lock member 14 is provided on the inner surface of the case body 2.
The lock member 14 is moved inward of the case body 2 in response to the opening of the lid 3, and the claw 13, the friction plate 27, etc. of the lock member 14 are pushed up by the plate 9. The push-up plate locking means 11 is designed to lock the push-up plate 9 at that position by engaging with the peripheral portion of the push-up plate 9, and the structure of the lock member 14 itself, for example, a strip 19 for forming a leaf spring. May be urged by a coil spring or the like without integrally forming the lock member 14, and without forming an accommodation space for the lock member 14 using the installation structure of the lock member 14, for example, the cover 12. The space may be formed in the case body 2, and furthermore, the projection 23 of the lid 3 directly abuts on the lock member 14 without using the operation structure of the lock member 14, for example, the operation plate 15. By locking member 1
For example, various modes can be adopted, for example, the operation of the control unit 4 is operated.

Although the operation of the lock member is linked to the opening of the lid 3, the present invention is not limited to this, and a push button or an operation lever may be separately provided on the upper part of the lid or on the wet tissue warmer. The lock member may be operated by operating the push button or the operation lever provided on the side surface.

FIG. 7 relates to a second embodiment of the present invention and is a perspective view conceptually showing a push-up plate locking means having a configuration different from that of the first embodiment. In this embodiment, a wire 28 is connected to the lower surface of the push-up plate 9,
The other end of the wire 28 is guided to the upper part of the case main body 2 via pulleys 29, 29 installed on the case main body 2, and the other end is wound around a drum 30 rotatably installed on the case main body 2. The drum 30 is urged by a torsion coil spring 31 to rotate in one direction. A driven gear 32 is fixed to a shaft 30 a of the drum 30, and a driving gear 33 is meshed with the gear 32. The driving gear 33 is driven by the opening operation of the lid 3, for example, the shaft 33 a is connected to the hinge 5 of the lid 3.
And so on. The drive gear 33 has a missing tooth portion 34 with missing teeth, and the missing tooth portion 34 corresponds to the driven gear 32 with the lid 3 closed, and a gear The link between 32 and 33 is broken. In addition,
The torsion coil spring 31 is for preventing the wire 28 from being loosened, and its urging force is extremely small as compared with the urging force of the coil spring 10 for urging the push-up plate 9 upward.

When the cover 3 is in the closed state, the push-up plate locking means 11 having the above-described structure is used to lock the gear 3.
The push-up plate 9 is urged upward by the biasing force of the coil spring 10 to push up the wet tissue pack A on the push-up plate 9 because the members 2 and 33 are not in the meshing state. When the lid 3 is opened, the driving gear 33
Is rotated. Then, the drive gear 33 meshes with the driven gear 32, the drum 30 is rotated via the driven gear 32, and the wire 28 is wound. Therefore, the push-up plate 9 is lowered against the urging force of the coil spring 10, the wet tissue pack A on the push-up plate 9 is lowered, and the press-contact with the inner lid 4 is released. This state is
It is maintained until the lid 3 is closed.

In this embodiment, the drum 30 is disposed in the case body 2, one end of the wire is connected to the push-up plate 9, and the other end of the wire is wound around the drum 30. The push-up plate locking means 11 is configured to take up the wire 28 by rotating in response to the opening of the lid 3, thereby lowering the push-up plate 9. Can be adopted. For example, in this embodiment, the shaft 33 a of the drive gear 33 is connected to the hinge 5 of the lid 3.
The rotation of the drum 30 is obtained by connecting to a rotating portion such as the above. However, it is also possible to obtain a rotation of the drum 30 by forming a rack on the lid 3 and meshing the rack with the driven gear 32. In this case as well, it is necessary to form a missing tooth portion on the rack.

In the second embodiment, the drive gear 33 is rotated in conjunction with the opening / closing operation of the lid 3; however, the present invention is not necessarily limited to this. A button or an operation lever may be provided on the upper part of the lid or on a side surface of the wet tissue warmer, and the drive gear 33 may be rotated by operating the push button or the operation lever. Furthermore, if a small motor is built in and the rotational force of the drive gear 33 is obtained by this, the opening / closing operation of the lid 3 can be lightened. Further, in the first and second embodiments, the lid has been described as having a structure in which the entirety is opened,
The present invention is not necessarily limited to this, and it goes without saying that only the portion of the small lid 106 such as the wet tissue warmer shown in FIG. 8 can be opened and closed.

In the first and second embodiments, the push-up plate is a flat plate.
Since there are various types of commercially available wet tissue packs, in order to optimally apply the present invention to all of these wet tissue packs, as shown in FIG. The shape should be good. In FIG. 9, 9 'is a push-up plate with a central convex portion of this raised bottom shape, 9'a is a central convex portion, and 9'b is a flat bottom portion. The reason why the push-up plate 9 ′ with the central convex portion is better than the push-up plate 9 having a flat shape will be described with reference to FIG. A commercially available wet tissue pack having a large pack size is 105 mm long x 165 mm wide x 65 height.
mm or 90 mm long x 170 mm wide x 50 mm high and smaller is 85 mm long x 155 mm wide x 45 height
mm, and there is a variety of packs whose ends are relatively soft and whose ends are relatively hard to crush. Therefore, when a pack whose end portion is softened is placed on the push-up plate 9 and pressed against the lid to be heated and used, the pack of the nap is easily crushed by the pressing force of the compression coil spring 10. There is no problem because it can be pressed against the lid, but in the case of a pack whose ends are relatively hard to collapse, FIG.
become that way. That is, in the case of a pack in which A is relatively hard to crush (the end of which is relatively hard to crush is referred to as A1 portion), the compression coil spring 1
With a pressing force F of 0, the end A1 of the pack is not crushed, and the gap t2
Therefore, the wet tissue a in the pack A cannot be pressed against the inner lid 4. Therefore, in order to press such a pack A against the inner lid 4,
It is necessary to use the compression coil spring 10 whose pressing force is larger than F. Then, conversely, tissue a
There is a problem that it becomes difficult to take out the wet tissue warmer from the wet tissue warmer.

Therefore, when the push-up plate 9 'is formed into a raised bottom shape having a central convex portion 9'a as shown in FIG. 9, its operation is as shown in FIG. That is, assuming that the end of the pack which is relatively hard to crush is A1 and the end which is relatively hard to crush is A1, the end A1 which is hard to crush is stored by the flat bottom portion 9'b without dare to crush. Since only the soft central portion of the pack A is lifted and crushed by the pressing force F by the central convex portion 9'a, the wet tissue a in the pack A can be pressed against the inner lid 4. As described above, in the case of the push-up plate 9 ′ having the central convex portion and the push-up plate 9 ′ having a flat plate shape, the nap can be pushed up with a smaller spring force than the push-up plate 9 ′ having the central convex portion. The pressing force against the lid is also reduced, and the take-out property is improved. Further, in a warmer having a structure in which the upper surface of the nap outlet is heated by a heater or the like, the nap can be appropriately pressed to the heater surface, so that an effect of improving thermal efficiency can be brought about. Further, since the portion actually used by heating is near the center, there is no particular problem even if the peripheral portion of the nap is not so heated.

[0023]

As described above, in the case for accommodating the wet tissue pack according to the present invention, the case body having the push-up plate urged upward therein and the opening of the case body are openably and closably covered. A lid provided with a heater inside, a wet tissue pack placed on the push-up plate of the case body is brought into contact with the lid with the lid closed, and the wet tissue pack is In the case where the wet tissue pack is warmed, a lock means is provided on the case body, and the lock means is interlocked with the opening of the lid so that the push-up plate stays at that position. According to this invention, when taking out the wet tissue,
By locking the push-up plate by the locking means, the bias on the wet tissue pack can be suppressed. Therefore, in the non-use state of the wet tissue, the wet tissue pack can be pressed against the heater portion with a strong force to sufficiently heat the wet tissue. It is possible to stop the press-contact with the heater unit to facilitate taking out the wet tissue.
