Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wet tissue warmer.
[0002]
[Prior art]
As a substitute for cloth towels, disposable wet tissues are widely used for cleaning towels, kitchens, toilets, and wiping infants and sick people. Such disposable wet tissue containers are roughly classified into three types: a bottle type (cylindrical shape), a box type (box shape), and a plastic bag type.
[0003]
In particular, when wet tissues for wiping the butt of infants and sick people are used at low temperatures such as in winter, the temperature of the wet tissue is low, which may cause discomfort to infants and sick people during use. was there.
For this reason, there has been a conventional wet tissue warming device that warms the entire wet tissue, but this consumes power, and it takes time to reach the optimum temperature, or a heating device with high power is required. I needed it.
[0004]
Therefore, the applicant invented and applied for a wet tissue warmer that solves these drawbacks (see Japanese Patent Application Laid-Open No. 8-117137). That is, a heating device is attached to the back side of the lid, and a wet tissue is pressed against the heating device to heat the upper tissue.
FIG. 10 illustrates this wet tissue warmer 100.
A case main body 103 having a push-up plate 102 urged upward by a spring 101 and a lid 104 that covers the opening 103a of the case main body 103 so as to be openable and closable are formed. 105, a small lid 106 is provided at the take-out port 105, and a heater unit 107 in which a heater 108 is housed in a portion of the lower part of the lid 104 excluding the tissue take-out port 105 is provided.
In this wet tissue warmer 100, as shown in FIG. 10, the wet tissue pack A is placed on the push-up plate 102, and the wet tissue pack A is brought into contact with the heater portion 107 of the lid 104 by the urging force of the spring 101. So that the wet tissue pack A is warmed. When using the wet tissue a, the small lid 106 is opened, and the wet tissues a are taken out one by one.
According to the wet tissue warmer 100, the vicinity of the tissue take-out portion of the wet tissue pack A can be heated preferentially, so that the used wet tissue a can be efficiently heated.
[0005]
[Problems to be solved by the invention]
By the way, there are various types of commercially available wet tissue packs, ranging from those having soft end portions to those having relatively hard end portions to be crushed. As shown in FIG. 10, the conventional wet tissue warmer push-up plate had a flat plate shape, so that not all of these wet tissue packs were optimally heated.
This is because when a pack having a soft end treatment is placed on a flat push-up plate 9 and pressed against a lid to be heated and used, the nap pack is easily crushed by the pressing force of the compression coil spring 10. Therefore, there is no problem because the pack can be pressed against the lid, but in the case of a pack whose end portion is relatively difficult to be crushed, a flat push-up plate is as shown in FIG. That is, in the case of a pack in which A is relatively hard to be crushed (the end of which is relatively hard to be crushed is referred to as A1 portion), the pack end A1 is pressed by the pressing force F of the compression coil spring 10. The gap t2 was not crushed and therefore the wet tissue a in the pack A could not be pressed against the inner lid 4.
Therefore, in order to press the pack A against the inner lid 4, it is necessary to use the compression coil spring 10 having a pressing force larger than F. Then, conversely, there is a problem that it becomes difficult to take out the tissue a when taking it out from the wet tissue warmer.
[0006]
Further, when the wet tissue pack A as shown in FIG. 10 is relatively crushed by the wet tissue warmer 100, the wet tissue pack A is pressed against the inner bottom surface of the lid 104 (the lower surface of the heater unit 107). Therefore, there is a problem that resistance is large and it is difficult to take out the wet tissue a.
Therefore, if the urging force to the wet tissue pack A is weakened to facilitate the removal of the wet tissue a, the wet tissue a may not adhere to the inner bottom surface of the lid 104, and the wet tissue a may not be heated sufficiently. There was this.
Accordingly, an object of the present invention is to solve the above-mentioned problems, and to provide a wet tissue warmer that can sufficiently heat a wet tissue to be used and that can be easily taken out.
[0007]
[Means for Solving the Problems]
The present invention solves the above problems, and claims. 1 The invention of the wet tissue warmer described is provided in a case body, a lid body that covers the upper opening of the case body so as to be openable and closable, a heater housed in the lid body, and a vertically movable body in the case body. In a wet tissue warmer that warms the wet tissue by placing the wet body in contact with the lid body in a state where the lid body is closed with the lid body closed, It is characterized by a raised bottom shape with the central part as a convex part upward.
[0008]
According to the above configuration, since the push-up plate has a raised bottom shape with the central portion as a convex portion upward, if this push-up plate is used as a push-up plate for a wet tissue warmer, the central portion of the pack A is formed by the central convex portion. Therefore, the wet tissue a in the pack A can be reliably pressed against the heater side.
[0009]
Claims 2 The wet tissue warmer described above is characterized in that it includes movement preventing means for preventing the upward movement of the push-up plate when the lid is opened and the wet tissue is taken out.
Claims 3 The described invention includes a movement preventing means that acts on the push-up plate in conjunction with opening of the lid and prevents the push-up plate from moving upward when the wet tissue is taken out. It is said.
Claims 4 In the described invention, the movement preventing means includes a lock member having a plurality of claws on a front surface, the lock member is disposed on an inner surface of the case body so as to be retractable inward, and the claws are pushed up. It is characterized by being configured to protrude into the moving area of the plate and engage with the side edge of the push-up plate.
Claims 5 According to the invention described above, the movement preventing means includes a drum, and the other end of a wire having one end connected to the push-up plate is wound around the drum, the drum is rotated, and the push-up plate is lowered. It is characterized by being.
Claims 6 The described invention includes an inner lid that is disposed between the lid and the push-up plate and is displaceable in the nap take-out direction.
[0010]
According to the above configuration, when the wet tissue is taken out, it is possible to suppress the urging to the wet tissue pack by locking the push-up plate by the movement preventing means such as the lock means. In a state, the wet tissue pack can be pressed against the lid with a built-in heater with a strong force to sufficiently heat the wet tissue. When using the wet tissue, the pressure contact with the lid is stopped. The wet tissue can be easily taken out.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the wet tissue warmer of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of a wet tissue warmer according to an embodiment of the present invention, and FIG. 2 is a perspective view of a raised bottom-shaped push-up plate schematically shown as 9 in FIG. FIG. 3 is an exploded perspective view showing the push-up plate locking means which is the main part of the wet tissue warmer, and FIGS. 4A and 4B are cross-sectional views of the main part showing the action of the push-up plate locking means. FIG. 5 is a perspective view showing a state in which the tissue is taken out from the case main body, and FIG.
In FIG. 1, a wet tissue warmer 1 includes a case main body 2, a lid 3, and an inner lid 4 on the case main body 2 side of the lid 3. In the wet tissue warmer 1, one side of the lid 3 and the inner lid 4 is engaged with the case body 2 by hinges 5 and 6, respectively, and is engaged with the case body 2 by engagement means 7 and 8 on the other side. ing.
The case main body 2 has a substantially rectangular shape whose horizontal cross section follows the shape of the wet tissue pack A, and has an opening 2a on the upper side. A push-up plate 9 is disposed in the case main body 2. Unlike the flat plate-like push-up plate 102 as shown in FIG. 10, the push-up plate 9 has a raised bottom shape with the central portion as a convex portion as shown in FIG. 2. In FIG. 2, 9 is a raised plate with a central convex portion having a raised bottom shape, 9a is a central convex portion, and 9b is a flat bottom portion.
The reason why the push-up plate 9 with the central convex portion is better than the flat push-up plate 102 will be described with reference to FIG. In FIG. 6, when the push-up plate 9 has a raised bottom shape having a central convex portion 9a as shown in the figure, the end portion A1 of the pack A, which is relatively hard to be crushed, is flattened without being crushed. It is accommodated by 9b, and only the soft center part of the pack A can be lifted and crushed by the small pressing force F by the center convex part 9a. Since the part that is actually heated and used is near the center, there is no particular problem even if the peripheral part of the nap is not heated so much.
As described above, according to the present invention, the end portion A1 which is not easily crushed in the pack A is not crushed, and only the central portion of the wet tissue a can be pressed against the inner lid 4 with a small spring force.
Thus, compared with the push-up plate 9 with the central convex portion and the flat push-up plate 9, the push-up plate 9 with the central convex portion can push up the nap with a smaller spring force. The pressing force is also reduced, and the take-out property is improved. In addition, in a warmer having a structure in which the upper surface of the nap take-out port is heated by a heater or the like, the nap can be appropriately pressure-bonded to the heater surface, so that an effect of improving thermal efficiency can be brought about.
[0012]
Returning to FIG. 1, the push-up plate 9 with the central convex portion 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.
Further, on the opposing inner side surfaces 2b, 2b of the case main body 2, push-up plate locking means 11 for locking the push-up plate which is energized and is going to go upward is disposed. The push-up plate locking means 11 is accommodated in the space 12 and the cover 12 as shown in FIG. 3 surrounding the inner side surfaces 2b and 2b of the case body 2 and defining the space, and the push-up plate 9 (see FIG. 1). The lock member 14 includes a plurality of claws 13 that engage with the lid 3 and the 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 cross section. A rectangular hole 16 is formed in the front plate 12 a located inside the case body 2. The cover 12 has a top plate 12b at the top, and a hole 17 is formed in the top plate 12b. Further, the cover 12 includes a boss 18 on the lower back surface of the front plate 12a.
The claw 13 of the lock member 14 is formed side by side in the vertical direction on the surface of the plate body 14a. Moreover, the strip 19 which comprises a leaf spring is extended in the back surface direction at the up-down direction intermediate | middle both sides of this board 14a.
Moreover, the action | operation board 15 has the hole 20 in the center part, and has the top plate 15a extended in the back surface direction at the upper part.
[0013]
As shown in FIG. 4A, 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 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.
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 portion 22 (see FIG. 1) with a heater built in the inner lower surface, a protrusion 23 (see FIG. 1) projecting downward on both sides, and a handle 24 (see FIG. 1) on the upper surface. See).
[0014]
The inner lid 4 is formed of a thin plate-like elastic resin or the like, and has an arcuate hole 25a, 25a formed on both sides, and a slit 25b connecting the holes 25a, 25a, and an H-shaped tissue outlet. 25, and a circular hole 25c is formed in the middle of the slit 25b. Further, holes 26 are formed on both side edges of the inner lid 4. With these configurations, it can be displaced in the direction of taking out the wet tissue.
Therefore, when the lid 3 is closed, the inner lid 4 is in contact with the lower surface of the lid 3 to transmit heat from the heater portion 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. Since the movement of the push-up plate is locked and the take-out port divided into two of the inner lid 4 is elastically bent, when the wet tissue is taken out, the take-out port bends elastically and has a slight upper part. Since the gap is generated, the wet tissue can be easily taken out.
The inner lid 4 is not limited to such an H-shaped tissue take-out port, and may be any material / configuration that can be displaced in the take-out direction of the wet tissue.
[0015]
The thus configured lid 3 and inner lid 4 are attached to the case body 2 by 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 through the push-up plate 9, and the upper surface thereof is brought into contact with the inner lid 4.
Moreover, the lid | cover 3 is closed in the non-use aspect of the wet tissue a.
Then, as shown in FIG. 4A, the protrusion 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. 4A, the protrusion operates to push down the operating plate 15. Therefore, when the operating plate 15 is pressed down, the claw 13 of the lock member 14 is pushed at the upper edge of the hole 20. Thus, the lock member 14 is retracted (in the direction of the side wall of the case main body). Therefore, the claw 13 of the lock member 14 is retracted from the front surface of the cover 12 to the inside, thereby allowing the push-up plate 9 to move freely.
Accordingly, 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 lid 4 is interposed in the middle, the wet tissue above the wet tissue pack A that is first taken out at the time of use is positioned close to the heater portion 22 in the lid 3 so that heating is performed efficiently. be able to.
[0016]
Next, when the lid 3 is opened in order to use the wet tissue a, as shown in FIG. 4B, the protrusion 23 of the lid 3 forms the hole 26 of the inner lid 4 and the cover 12 constituting the locking means 11. Escape from the hole 17. Then, the lock member 14 protrudes inward of the case main body 2 by a distance t 1 while pushing up the operating plate 15 that has pushed the lock member 14 upward by the urging force of the strip 19, and immediately above the edge of the push-up plate 9. The claw 13 located at the position 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 no further upward movement is performed.
Therefore, when the wet tissue a is taken out from the wet tissue pack A in this restrained state, the edge of the tissue take-out port 25 of the inner lid 4 is bent upward together with the wet tissue a as shown in FIG. Since a slight gap is formed in the vertical direction, the wet tissue a can be easily taken out from the case body 2.
As described above, in the first embodiment, the lock member 11 is operated by forming the inclined surface on the upper surface of the claw 13 of the lock member 14 and pressing the operating plate 15 against the inclined surface. In addition, by engaging the lower surface (horizontal surface) of the claw 13 with the push-up plate 9, the upward movement of the push-up plate 9 is prevented, and coupled with this, the tissue outlet 25 of the elastic inner lid 4 is bent. When taking out one wet tissue, a gap is formed in the nap take-out direction, so that it is easy to take out, and since some tension is applied to the wet tissue, only one piece is easily separated from other wet tissues.
[0017]
Further, as a modification of the first embodiment, there is a wet tissue warmer shown in FIG. As shown in the figure, an inclined surface is formed on the lower surface of the claw 13, and when the claw 13 comes into contact with the push-up plate 9, as shown in FIG. Is trying to lower.
Further, in FIG. 8 (a), a friction plate 27 is provided in place of the claw 13 except the claw (the uppermost and lowermost claws in the figure) with which the operating plate 15 abuts, and FIG. 8 (b). As shown in FIG. 5, the friction plate 27 may be pressed against the push-up plate 9 to prevent the push-up plate 9 from moving upward.
[0018]
In the first embodiment and the modification, the lock member 14 is disposed on the inner surface of the case body 2 so as to be retractable inward of the case body 2, and the lock member 14 is moved in response to the opening of the lid 3. A push-up plate lock which is moved inward of the case body 2 and engages the claw 13 and the friction plate 27 of the lock member 14 with the peripheral edge of the push-up plate 9 to lock the push-up plate 9 in its position. The means 11 is illustrated, and the lock member 14 may be urged by a coil spring or the like without integrally forming the structure of the lock member 14 itself, for example, a strip 19 for constituting a leaf spring, An installation structure of the lock member 14, for example, the cover 12 may be used to form the space in the case body 2 without forming the storage space for the lock member 14. Actuation structure, for example, without using the operation plate 15, by direct contact to the locking member 14 the projection 23 of the cover 3, may be employed equally to actuate the locking member 14, the various aspects.
[0019]
Further, although the operation of the locking member is interlocked with the opening of the lid 3, the present invention is not limited to this, and a push button or an operating lever is separately provided on the upper portion of the lid or the side of the wet tissue warmer. In addition, the lock member may be operated by operating the push button or the operation lever.
[0020]
FIG. 9 relates to the 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 body 2 via pulleys 29, 29 installed on the case body 2, and the other end is connected to the case. It is wound around a drum 30 that is rotatably installed on the main body 2.
The drum 30 is biased to rotate in one direction by a torsion coil spring 31. A driven gear 32 is fixed to the shaft 30 a of the drum 30, and a drive gear 33 is engaged with the gear 32. For example, a shaft 33 a is coupled to the hinge 5 of the lid 3 or the like so that the drive gear 33 is driven by the opening operation of the lid 3. The drive gear 33 has a missing tooth portion 34 with missing teeth. The missing tooth portion 34 corresponds to the driven gear 32 in a state where the lid 3 is closed. The link between 32 and 33 is broken. The torsion coil spring 31 is for preventing the wire 28 from slacking, and compared with the biasing force of the coil spring 10 biasing the push-up plate 9 with the central convex portion according to the present invention upward. The biasing force is extremely small.
[0021]
When the lid 3 is in the closed state, the push-up plate locking means 11 configured in this way is biased upward by the biasing force of the coil spring 10 because the gears 32 and 33 are in the non-meshing state. The wet tissue pack A on the push-up plate 9 is pushed up.
When the lid 3 is opened, the drive gear 33 is rotated in conjunction therewith. 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 up. 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 pressure contact with the inner lid 4 is released. This state is maintained until the lid 3 is closed.
[0022]
In this embodiment, the drum 30 is disposed on the case body 2, one end of the wire is connected to the push-up plate 9, the other end of the wire is wound around the drum 30, and the drum 30 is covered with the lid 3. The push-up plate locking means 11 is shown by taking up the wire 28 by rotating in response to the opening of the plate, thereby lowering the push-up plate 9, and the rotary drive mechanism of the drum 30 adopts various modes. be able to.
For example, in this embodiment, the rotation of the drum 30 is obtained by connecting the shaft 33a of the drive gear 33 to a rotating part such as the hinge 5 of the lid 3, but a rack is formed on the lid 3, and the rack is The rotation of the drum 30 can also be obtained by meshing with the driven gear 32. In this case also, it is necessary to form a missing tooth portion in the rack.
[0023]
Also in the second embodiment, the drive gear 33 is rotated in conjunction with the opening / closing operation of the lid 3, but the present invention is not necessarily limited to this, and a separate push button or operation is possible. A lever may be provided on the upper part of the lid or the 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 with this, the opening / closing operation of the lid 3 can be lightened.
Furthermore, in both the first and second embodiments, the lid has been described as having a structure in which the entire lid opens, but the present invention is not necessarily limited to this, and the wet tissue warmer shown in FIG. Of course, only such a small lid 106 may be opened and closed.
[0024]
【The invention's effect】
As described above, since the push-up plate 9 with the central convex portion according to the present invention is used, the nap is warmed up in a short time (within about 40 minutes) in the order of use, and the end surface of the nap is not easily crushed. In addition, even if the number of naps is reduced, the pack is surely pressed against the upper surface, and the central part is reliably crushed by the raised bottom, so that the last one is warmed as before. In addition, the raised bottom shape can reduce the spring force required for crushing the pack, so that it can be easily removed from the outlet.
[0025]
Further, the wet tissue pack storage case is configured by a case main body provided with a push-up plate biased upward inside, and an opening of the case main body that can be opened and closed, and a lid provided with a heater inside. In the wet tissue pack housing case, the wet tissue pack placed on the push-up plate of the case body is brought into contact with the lid with the lid closed to warm the wet tissue pack. Locking means is disposed on the case body, and the locking means is interlocked with the opening of the lid so that the push-up plate stays in that position.
According to this invention, when taking out the wet tissue, the urging force to the wet tissue pack can be suppressed by locking the push-up plate by the locking means. Therefore, when the wet tissue is not used, the wet tissue pack can be pressed against the heater part with a strong force to sufficiently heat the wet tissue. It is possible to easily remove the wet tissue by stopping the pressure contact with the heater.
[0026]
Further, since an inner lid that is displaceable in the nap removal direction is provided between the lid and the push-up plate, a slight gap is formed in the nap removal direction when one wet tissue is taken out, so that a gap is formed and the removal is easy. At the same time, since some tension is applied to the wet tissue, only one sheet can be easily separated from the other wet tissue.
