Detailed Description

< embodiment 1 >

Hereinafter, the wet tissue paper towel heater according to embodiment 1 will be described with reference to the drawings. Here, fig. 1A to 13 are views showing a wet tissue heater according to embodiment 1 of the present disclosure.

As shown in fig. 1A to 4C, the wet tissue heater 1 according to embodiment 1 stores a wet tissue storage body 2A containing a plurality of wet tissues 2 in a container 3 (for example, a plastic bag) made of a flexible material, and supplies the wet tissues 2 heated to a temperature higher than the normal temperature (see fig. 1B).

As shown in fig. 1A, such a wet tissue heater 1 includes: a synthetic resin container body 10 having a side wall 11 including 4 side surfaces and a bottom surface 12, and having an upper opening 10a formed above the side wall 11; an inner lid 20 made of synthetic resin, openably and closably provided in the container body 10, closing an upper opening 10a of the container body 10, and having a take-out port 21 for the wet tissue 2; a lid device 30 openably and closably provided in the container body 10, covering the inner lid 20 and closing the container body 10; a synthetic resin push-up plate 40 is disposed in the container body 10 and pushes up the wet tissue storage body 2A.

The cover device 30 has a synthetic resin lower plate 33, a synthetic resin upper plate 34, and a synthetic resin side plate 35 between the lower plate 33 and the upper plate 34, and a hollow space 30a is formed therein.

As will be described later, a heating mechanism 36A (see fig. 4A to 4C) for heating the wet tissue 2 via the lower plate 33 is disposed in the space 30a of the cover device 30.

Further, a metal spring (push-up plate urging mechanism) 5 is provided in the container body 10, and is interposed between the bottom surface 12 of the container body 10 and the push-up plate 40 to lift the push-up plate 40. Further, a pair of

stopper mechanisms

50, 50 for locking the push-up plate 40 are provided on the side surfaces of the side wall 11 of the container body 10 facing each other, for example, the inner surfaces of the side surfaces 11a, 11 b.

Next, the respective constituent parts of the wet tissue heater 1 will be further explained. The inner lid 20 and the lid device 30 of the wet tissue heater 1 each have a base portion 23A and a base portion 33A rotatably attached to the swing shaft 8 provided at the upper edge of the upper opening of the container body 10. The lid device 30 and the inner lid 20 are both urged in the opening direction by

springs

9a and 9b provided on the swing axis of the container body 10.

The cap device 30 further includes a locking body 31 that is locked to the engagement portion 17 provided in the container body 10. The locking body 31 is provided on a side plate 35 of the cover device 30, and an operating body 32 for moving the locking body 31 along the side plate 35 is provided on the side plate 35. Then, by moving the operating body 32 with a finger, the locking body 31 of the lid device 30 is disengaged from the engaging portion 17 of the container body 10, and the lid device 30 is opened by the force of the spring 9 a. As shown in fig. 4B, the operating body 32 is coupled to an operating rod 32a having a spring 32B wound therearound, and the spring 32B biases the operating body 32 in a locking direction in which the operating body is locked to the engagement portion 17 of the locking body 31.

The inner lid 20 has a pair of locking bodies 22 that are locked to a pair of engagement portions 18 provided in the container body 10, and the pair of locking bodies 22 are moved inward toward each other by a finger. Thereby, the locking body 22 of the inner lid 20 is disengaged from the engagement portion 18 of the container body 10, and the inner lid 20 is opened by the force of the spring 9 b.

Next, the cover device 30 will be explained with reference to fig. 4A to 4C. As shown in fig. 4A to 4C, the cover device 30 includes a lower plate 33, an upper plate 34, and a side plate 35 between the lower plate 33 and the upper plate 34, and a heating mechanism 36A for heating the wet tissue 2 via the lower plate 33 is disposed in the space 30a of the cover device 30. The heating mechanism 36A includes a heat plate 38 made of aluminum provided on the lower plate 33 and a heater 36 provided on the heat plate 38. Further, a grip groove 30A into which fingers can be inserted is provided on the upper plate 34 of the cover device 30.

The heater 36 includes: the heater elements 36 a; the pair of

electrodes

36b and 36c are provided on the lower surface and the upper surface of the heater element 36a, and the platen 36d is provided on the upper surface of the electrode 36 c.

The heater element 36a, the pair of

electrodes

36b and 36c, and the platen 36d are fixed to the hot plate 38 by screws 36e penetrating the heater element 36a, the pair of

electrodes

36b and 36c, and the platen 36 d.

The pair of

electrodes

36b and 36c are connected to the

wires

37b and 37c, respectively, and the

wires

37b and 37c are provided in the container body 10 via the collective wire 37d and connected to the socket 70 (see fig. 12) exposed to the outside. As will be described later, the receptacle 70 of the container body 10 is connected to the magnet connector 81 provided in the base 80 by placing the container body 10 on the base 80.

As shown in fig. 4B and 4C, in order to prevent heat from the heating means 36A from being transmitted to the upper plate 34 side, a heat insulating material 39 made of a foamable synthetic resin is provided between the heating means 36A composed of the hot plate 38 and the heater 36 provided on the lower plate 33 of the cover device 30 and the upper plate 34. Therefore, the heat from the heating mechanism 36A is transferred to the wet tissue storage 2A side via the lower plate 33, but not to the upper plate 34 side.

The lower plate 33 of the lid device 30 has a convex portion 33a protruding downward toward the container body 10, and the heating mechanism 36A is disposed inside the convex portion 33 a. Further, by moving the heating mechanism 36A in the cover device 30 further toward the push-up plate 40 by the convex portion 33a, the wet tissue storage 2A on the push-up plate 40 can be efficiently heated while pressing the wet tissue storage 2A by the force of the spring 5 between the convex portion 33a of the lower plate 33 and the push-up plate 40. Further, the concave portion 23 into which the convex portion 33a of the lower plate 33 enters is formed in the inner lid 20, and the convex portion 33a of the lower plate 33 is fitted into the concave portion 23 of the inner lid 20, whereby the inner lid 20 can be covered in a sealed state by the lid device 30.

Next, a pair of stopper mechanisms 50 provided on the inner surfaces of the opposing side surfaces 11a and 11B of the container body 10 and engaged with the push-up plate 40 to stop the upward movement of the push-up plate 40 will be described with reference to fig. 8A to 10B. As shown in fig. 8A to 10B, each stopper mechanism 50 has the same structure. That is, the stopper mechanism 50 has: a stopper housing 51 fixed to the container body 10; the pair of stopper frames 52 and 53 are housed in the stopper case 51 so as to be movable in the vertical direction and the lateral direction, and a plurality of

claws

52a and 53a protruding laterally outward from the stopper case 51 are provided to the respective stopper frames 52 and 53. The stopper mechanism 50 having such a configuration is fixed to the inside of the container body 10 by a set screw 61. In this case, the stopper case 51 of each stopper mechanism 50 has a flat surface 51A, and each stopper mechanism 50 is disposed so that the flat surface 51A faces the inside of the container body 10.

In this case, the stopper housing 51 of each stopper mechanism 50 has a thin box shape whose width a is larger than its thickness b. The stopper housing 51 is disposed along the inner surfaces of the side surfaces 11a and 11B so that the direction of the width a (hereinafter referred to as the width direction) is parallel to the opposing side surfaces 11a and 11B of the container body 10, in order to suppress the amount of protrusion into the container body 10 (see fig. 8A and 8B). The

claws

52a and 53a of the

stopper holder

52 and 53 housed in the stopper housing 51 protrude in directions parallel to the side surfaces 11a and 11b of the container body 10, respectively. Thus, the stopper housing 51 of the stopper mechanism is formed to be thin, and is disposed so that the width direction thereof is parallel to the side surfaces 11a and 11b, and the

claws

52a and 53a of the

stopper holder

52 and 53 are both projected in the direction parallel to the side surfaces 11a and 11b of the container main body 10, so that the stopper mechanism 50 can be configured to be as thin as possible. Further, the amount of protrusion of the stopper mechanism 50 into the container body 10 can be suppressed as much as possible.

Since the

claws

52a, 53a of the stopper frames 52, 53 are projected in the direction parallel to the side surfaces 11a, 11b of the container body 10, the direction of the thickness b of the stopper mechanism 50 (hereinafter referred to as the thickness direction) is orthogonal to the projection direction of the

claws

52a, 53a of the stopper frames 52, 53. Therefore, even if the stopper mechanism 50 is configured to be thin, the engagement between the

claws

52a and 53a of the stopper frames 52 and 53 and the push-up plate 40 is not easily disengaged. That is, when the

claws

52a and 53a of the

stopper holders

52 and 53 of the stopper mechanism 50 are orthogonal to the side surfaces 11a and 11b of the container body 10 and project toward the inside of the container body 10, it is considered that if the thickness of the stopper mechanism 50 is reduced, the projecting amount of the

claws

52a and 53a is also reduced, and the

claws

52a and 53a of the

stopper holders

52 and 53 are easily disengaged from the push-up plate 40. In contrast, according to the present embodiment, the thickness direction of the stopper mechanism 50 is orthogonal to the protruding direction of the

claws

52a and 53a of the stopper frames 52 and 53 and the push-up plate 40 is not easily disengaged.

In the present specification, the "vertical direction" refers to a "vertical direction" in the case where the bottom surface 12 of the wet tissue paper towel heater 1 is placed downward, and the "vertical direction of the stopper mechanism 50" refers to a "vertical direction of the stopper mechanism 50" as shown in fig. 9A to 9D in the case where the bottom surface 12 of the wet tissue paper towel heater 1 is placed downward. The "lateral direction of the stopper mechanism 50" refers to a direction parallel to the side surfaces 11a and 11b of the container body 10 and also coincides with the width direction of the stopper case 51, as shown in fig. 9A to 9D, "lateral direction (left-right direction) of the stopper mechanism 50" in the case where the bottom surface 12 of the wet tissue heater 1 is placed downward.

As shown in fig. 8A to 10B, the stopper holder 52 has a plurality of claws 52a aligned in the vertical direction among a pair of

stopper holders

52, 53 housed in the stopper housing 51, and is movable in the vertical direction and the lateral direction in the stopper housing 51.

The stopper holder 53 has a plurality of claws 53a arranged in the vertical direction, and is movable in the vertical direction and the lateral direction in the stopper housing 51.

The stopper housing 51 is provided with a pair of pins 58 arranged in the vertical direction, and the

stopper holders

52 and 53 are provided with a pair of inclined holes 52b and 53b into which the pins 58 are inserted.

Further, as shown in fig. 9A and 9B, springs (stopper holder biasing mechanisms) 54 and 55 are provided in the

respective stopper holders

52 and 53 so as to be aligned in the vertical direction, the stopper holder 52 is biased outward on one side (right side) in the lateral direction by the spring 54, and the stopper holder 53 is biased outward on the other side (left side) in the lateral direction by the spring 55.

As shown in fig. 9C and 9D, the stopper holder 53 is provided with a pair of inclined holes 53b that enter the pair of pins 58 of the stopper housing 51 as described above, and further, springs 55, 55 arranged in the vertical direction of the stopper holder 53 are attached to the outer peripheries of a pair of

support pins

55a, 55a provided in the stopper holder 53.

As shown in fig. 9C and 9D, the stopper holder 52 also has the same structure as the stopper holder 53.

An upper body 59 is disposed above each of the retainer frames 52 and 53. When the lid device 30 is closed with respect to the container body 10, the upper body 59 is pressed downward by the projection 60 of the lid device 30. When the upper body 59 is pressed downward by the projection 60 of the cover device 30, the upper body 59 moves the stopper frames 52 and 53 downward (see fig. 10A).

At this time, since the pin 58 of the stopper housing 51 is fitted into the inclined holes 52b, 53b of the stopper frames 52, 53, the stopper frame 52 moves downward in the stopper housing 51 in the left direction against the force of the spring 54 as shown in fig. 9A. At this time, the claw 52a of the stopper holder 52 is retracted inward from one lateral side (right side) of the stopper housing 51.

Similarly, the stopper holder 53 moves downward rightward against the force of the spring 55 in the stopper housing 51. At this time, the claw 53a of the stopper holder 53 is retracted inward from the other lateral side (left side) of the stopper housing 51 (see fig. 9A).

In this way, when the claw 52a of the stopper holder 52 of the stopper mechanism 50 is retracted inward from one lateral side and the claw 53a of the stopper holder 53 is retracted inward from the other lateral side, the claw 52a of the stopper holder 52 and the claw 53a of the stopper holder 53 are disengaged from the push-up plate 40 as described below.

In addition, when the cap device 30 is opened from the container body 10, the protrusion 60 of the cap device 30 is separated from the upper body 59. Accordingly, in the stopper housing 51, since the pin 58 is inserted into the inclined hole 52b, the stopper holder 52 is returned upward in the right direction by the force of the spring 54, and the claw 52a of the stopper holder 52 protrudes outward from one lateral side (right side) of the stopper housing 51 (fig. 9A to 9D).

Similarly, since the pin 58 is inserted into the inclined hole 53b, the stopper holder 53 is returned upward in the left direction by the force of the spring 55, and the claw 53a of the stopper holder 53 protrudes outward from the other lateral side (left side) of the stopper housing 51 (fig. 9A to 9D).

In this way, the claw 52a of the stopper holder 52 of the stopper mechanism 50 protrudes outward from one lateral side, and the claw 53a of the stopper holder 53 protrudes outward from the other lateral side, whereby the claw 52a of the stopper holder 52 and the claw 53a of the stopper holder 53 are engaged with the push-up plate 40.

Next, the internal structure of the container body 10 will be described with reference to fig. 7. As shown in fig. 7, a spring housing wall (push-up plate urging mechanism housing wall) 14 for housing one end of the spring 5 is provided on the bottom surface 12 of the container body 10. The spring housing wall 14 is formed intermittently, and moisture discharge openings 14a are provided at predetermined intervals in the spring housing wall 14. It is considered that since the wet wipe 2 releases moisture from the inside in use, moisture from the wet wipe 2 accumulates on the bottom surface 12, particularly on the region 12A surrounded by the spring housing wall 14.

In the present embodiment, a plurality of ribs 15 are provided on the inner surface of the spring housing wall 14, and the spring 5 is disposed in the spring housing wall 14 and supported by the plurality of ribs 15. This can reliably prevent corrosion or deterioration of the metal spring 5 due to moisture accumulated in the region 12A of the bottom surface 12. Further, moisture accumulated in the region 12A inside the spring housing wall 14 in the bottom surface 12 can be discharged to the region 12B other than the region 12A through the moisture discharge opening 14 a.

Further, a convex portion 16 that is retracted inward is formed on the bottom surface 12 of the container body 10, and the convex portion 16 corresponds to a concave groove 72 that is retracted with respect to an outer surface of the bottom surface 12, which will be described later. In addition, an auxiliary rib 11e extending in the vertical direction is provided on the inner surface of the side wall 11 of the container body 10, and an auxiliary rib 12a is also provided on the bottom surface 12.

However, as shown in fig. 5 and 6, the push-up plate 40 housed in the container body 10 has a spring housing wall 44 housing the other end of the spring 5 whose one end is housed in the spring housing wall 14 of the bottom surface 12. The push-up plate 40 has a substantially rectangular shape in a plan view, and recesses (locking recesses) 41, 41 into which the stopper mechanism 50 enters are provided on both

sides

40a, 40b corresponding to the side surfaces 11a, 11b of the container body 10. In this case, the

concave portions

41, 41 are provided in the central portions of the two

sides

40a, 40b of the push-up plate 40. The

claws

52a, 53a of the stopper mechanism 50 that have entered the

recesses

41, 41 of the push-up plate 40 engage with both

end portions

41a, 41a located in a direction parallel to both

sides

40a, 40b of the recesses 41, thereby locking the push-up plate 40. Further, the push-up plate 40 is provided with a guide groove 42, and the guide groove 42 is engaged with an auxiliary rib 11e extending in the vertical direction of the container body 10, and guides the push-up plate 40 along the auxiliary rib 11 e.

As shown in fig. 11A to 13, the wet tissue heater 1 further includes a base 80 on which the container body 10 is placed. In this case, a magnet connector 81 is provided on the base 80, and a wiring wire 83 connected to a power supply (not shown) is connected to the magnet connector 81.

Further, the base 80 is provided with a pair of

guide projections

82, 82 extending parallel to the direction L in which the magnet connector 81 faces, so that each

guide projection

82, 82 is fitted into a pair of concave grooves 72 provided outside the bottom surface 12 of the container body 10. In this case, the magnet connector 81 is located at the center between extension lines L1 of the pair of

guide projections

82, 82. The direction L in which the magnet connector 81 faces is parallel to the insertion direction of the container body 10 described later.

As described above, the socket 70 exposed to the outside is provided under the side wall 11 of the container body 10, and the socket 70 of the container body 10 is attracted to the magnet connector 81 of the base 80 in one touch to be electrically connected.

In this case, the pair of

guide projections

82, 82 of the base 80 have gentle mountain shapes when viewed from a side surface orthogonal to the direction L in which the magnet connector 81 faces, and the concave groove 72 on the container body 10 side also has a mountain shape corresponding to the

guide projections

82, 82.

As shown in fig. 12, fingers are inserted into a holding groove 30A of a cover device 30 provided in the wet tissue heater 1, and the cover device 30 is held with one hand. Next, the container body 10 and the cover device 30 are placed on the base 80 so that the socket 70 faces the magnet connector 81 side. At this time, the

guide projections

82 and 82 on the base 80 are fitted into the concave groove 72 on the container body 10 side. Thereafter, the container body 10 and the cover device 30 are slid toward the magnet connector 81 along the insertion direction in which the pair of

guide projections

82, 82 extend.

In this case, since the

guide projections

82 and 82 on the base 80 have a gentle mountain shape when viewed from the side, when the container body 10 is moved toward the magnet connector 81, the height of the container body 10 gradually decreases downward. Thus, when the socket 70 of the container body 10 approaches the magnet connector 81, the height of the socket 70 and the height of the magnet connector 81 are matched (see fig. 13). Further, by moving the container body 10 and the lid device 30 toward the magnet connector 81, the socket 70 of the container body 10 can be attracted and connected to the magnet connector 81 of the base 80 in one touch by only one-handed operation.

When the container body 10 is removed from the base 80, first, the container body 10 is rotated upward about the connection portion between the socket 70 and the magnet connector 81 by grasping the grasping groove 30A of the container body 10, and the socket 70 and the magnet connector 81 are released from connection. Next, the container body 10 is separated from the magnet connector 81 of the base 80. This allows the container body 10 to be easily removed from the base 80.

However, in the present embodiment, it is preferable that the peak P1 of the pair of

guide projections

82, 82 is positioned on the magnet connector 81 side with respect to the peak P2 of the pair of

concave grooves

72, 72 in a state where the socket 70 is connected to the magnet connector 81 (see fig. 11B). In this case, when the pair of

concave grooves

72 and 72 are fitted to the pair of

guide protrusions

82 and 82 of the base 80 and the container body 10 is slid on the base 80 toward the magnet connector 81, the pair of

concave grooves

72 and 72 can be pressed toward the magnet connector 81 by the pair of

guide protrusions

82 and 82. This allows the socket 70 of the container body 10 to be pressed against the magnet connector 81 of the base 80, thereby reliably connecting the socket 70 and the magnet connector 81. Here, fig. 11B is a schematic view showing a pair of guide projections and a pair of concave grooves.

Next, the operation of the present embodiment having such a configuration will be described.

First, the operating body 32 of the cover device 30 provided in the wet tissue heater 1 is operated to release the engagement between the locking body 31 and the engagement portion 17 of the container body 10, and the cover device 30 is opened by the force of the spring 9 a.

Next, the pair of locking bodies 22 of the inner lid 20 are moved in the direction to approach each other, the engagement between the pair of locking bodies 22 and the engagement portion 18 of the container body 10 is released, and the inner lid 20 is opened by the force of the spring 9b (see fig. 2).

In this case, since the protrusions 60 of the cover device 30 are separated from the upper bodies 59 of the pair of stopper mechanisms 50, the

claws

52a and 53a of the

stopper holder

52 and 53 of the stopper holder 50 of the stopper mechanism 50 protrude outward from both lateral sides of the stopper housing 51 due to the forces of the

springs

54 and 55. Thereafter, the wet tissue storage body 2A is placed on the push-up plate 40 in the container body 10.

Next, the wet tissue storage body 2A on the push-up plate 40 is pushed downward from above. In this case, the

claws

52a and 53a of the

stopper holder

52 and 53 have a mountain shape, and each of the

claws

52a and 53a has an inclined upper surface 62 and a horizontally formed lower surface 63. Therefore, the push-up plate 40 slides on the upper surface 62 of the claw 52a of the stopper frame 52 and the upper surface 62 of the claw 53a of the stopper frame 53, and the claw 52a of the stopper frame 52 and the claw 53a of the stopper frame 53 are retracted inward from both lateral sides with respect to the stopper housing 51 and move downward. Thereafter, the push-up plate 40 reaches below the lowermost claw 52a of the stopper frame 52 and below the lowermost claw 53a of the stopper frame 53.

Thereafter, the inner lid 20 is closed, the upper opening 10a of the container body 10 is closed by the inner lid 20, and thereafter the lid device 30 is closed, and the inner lid 20 is covered by the lid device 30.

In this case, the projection 60 of the lid device 30 extends downward through the opening 20a of the inner lid 20 and the upper end opening 51a of the stopper housing 51 of the stopper mechanism 50, and presses the upper body 59 downward. Thereby, the pawls 52a of the stopper holder 52 and the pawls 53a of the stopper holder 53 are retracted inward from both lateral ends of the stopper housing 51.

Therefore, the push-up plate 40 is pushed up to the upper side by the force of the spring 5 without being restricted by the stopper mechanism 50, and the wet tissue storage 2A on the push-up plate 40 is pressed to the lower surface of the lower plate 33 of the cover device 30.

During this time, the wet tissue 2 in the wet tissue storage 2A is heated by the heating mechanism 36A incorporated in the cover device 30 via the lower plate 33.

In use, the lid device 30 is opened from the container body 10 (see fig. 4A).

Then, the wet tissue 2 in the wet tissue storage 2A heated by the heating mechanism 36A can be taken out to the outside through the take-out port 21 of the inner lid 20.

In this case, since the cap device 30 is opened from the container body 10, the projection 60 of the cap device 30 is separated from the upper body 59 of the stopper mechanism 50. Accordingly, the

claws

52a and 53a of the

stopper holder

52 and 53 of the stopper mechanism 50 protrude outward from both lateral sides of the stopper housing 51, and the push-up plate 40 engages with the lower surfaces 63 of the

claws

52a and 53a, thereby preventing the upward movement thereof. Thus, the wet tissue 2 can be smoothly taken out from the take-out port of the inner lid 20 without applying a large force to the wet tissue storage body 2A from the push-up plate 40.

Next, the operation of attaching the container body 10 to the base 80 will be explained.

First, as shown in fig. 12, fingers are inserted into a holding groove 30A provided in the cover device 30 of the wet tissue heater 1, and the cover device 30 is held with one hand. Next, the container body 10 and the cover device 30 are placed on the base 80 so that the socket 70 faces the magnet connector 81 side. At this time, the

guide projections

82 and 82 on the base 80 are fitted into the concave groove 72 on the container body 10 side. Thereafter, the container body 10 and the cover device 30 are slid toward the magnet connector 81 side along the direction in which the pair of

guide protrusions

82, 82 extend.

In this case, since the

guide projections

82 and 82 on the base 80 have a gentle mountain shape when viewed from the side, when the container body 10 is moved toward the magnet connector 81, the height of the container body 10 gradually decreases downward. Thus, when the socket 70 of the container body 10 approaches the magnet connector 81, the height of the socket 70 and the height of the magnet connector 81 are matched (see fig. 13). Further, by moving the container body 10 and the cover device 30 toward the magnet connector 81, the socket 70 of the container body 10 can be attracted and connected to the magnet connector 81 of the base 80 in one touch by only one-handed operation.

As described above, according to the present embodiment, the pair of stopper mechanisms 50 provided in the container body 10 includes the stopper housing 51 having a thin box shape in which the width a is larger than the thickness b, and the stopper housing 51 is disposed along the inner surfaces of the side surfaces 11a and 11b so as to be parallel to the side surfaces 11a and 11b facing each other of the container body 10. The

claws

52a and 53a of the

stopper holder

52 and 53 project in parallel to the side surfaces 11a and 11b of the container body 10. Therefore, the stopper mechanism 50 can be configured as thin as possible, and therefore the amount of protrusion of the stopper mechanism 50 into the container body 10 can be suppressed. Further, since the stopper housing 51 has the pair of pins 58 arranged in the vertical direction and the

stopper holders

52 and 53 have the

springs

54 and 55 arranged in the vertical direction, the

stopper holders

52 and 53 can be moved in the lateral direction with high accuracy without being inclined.

Furthermore, since the

claws

52a and 53a of the stopper frames 52 and 53 project in the direction parallel to the side surfaces 11a and 11b of the container body 10, even if the stopper mechanism 50 is configured to be thin, the

claws

52a and 53a of the stopper frames 52 and 53 are not easily disengaged from the push-up plate 40. That is, when the

claws

52a and 53a of the stopper frames 52 and 53 of the stopper mechanism 50 are projected so as to be orthogonal to the side surfaces 11a and 11b of the container body 10, it is considered that if the thickness of the stopper mechanism 50 is reduced, the projection amount of the

claws

52a and 53a is also reduced, and the engagement between the

claws

52a and 53a of the stopper frames 52 and 53 and the upper push plate 40 is easily disengaged. In contrast, according to the present embodiment, the thickness direction of the stopper mechanism 50 is orthogonal to the protruding direction of the

claws

A spring housing wall 14 for housing one end of the spring 5 is provided on the bottom surface 12 of the container body 10, a plurality of ribs 15 are provided on the inner surface of the spring housing wall 14, and the spring 5 is placed on the ribs 15. Therefore, even if moisture released from the wet tissue 2 accumulates in the region 12A of the bottom surface 12 in the spring housing wall 14, the metal spring 5 does not corrode.

Further, a pair of

parallel guide projections

82, 82 are provided on the base 80, and a pair of

concave grooves

72, 72 into which the

guide projections

82, 82 are fitted are provided on the bottom surface of the container body 10. Therefore, the receptacle 70 of the container body 10 can be attracted and connected to the magnet connector 81 of the base 80 in one touch by merely holding the container body 10 and the cap device 30 with one hand, fitting the pair of

concave grooves

72, 72 of the container body 10 to the pair of

guide projections

82, 82 on the base 80, and sliding the container body 10 along the base 80 toward the magnet connector 81. In this case, the base 80 having the magnet connector 81 and the container body 10 having the socket 70 constitute a cradle structure.

The lower plate 33 of the lid device 30 has a protrusion 33a protruding downward, and the space 30a inside the lid device 30 can be obtained more widely by the protrusion 33 a. Further, since the lower plate 33 has the convex portion 33a protruding downward toward the container body 10 side and the heating mechanism 36A is disposed inside the convex portion 33a, the heating mechanism 36A in the lid device 30 can be moved further toward the upper push plate 40 side by the convex portion 33 a. Therefore, the wet tissue storage 2A can be heated efficiently while the wet tissue storage 2A is pressed between the convex portion 33a of the lower plate 33 and the push plate 40 by the force of the spring 5 by the heating mechanism 36A located on the push plate 40 side. Further, by providing the convex portion 33a in the lower plate 33, the space between the heating mechanism 36A and the upper plate 34 can be obtained more widely, and the heat insulator 39 having a large thickness can be disposed between the heating mechanism 36A and the upper plate 34. This can effectively prevent heat from the heating mechanism 36A from being transmitted to the upper plate 34 side. Further, the concave portion 23 into which the convex portion 33a of the lower plate 33 enters is formed in the inner lid 20, and the convex portion 33a of the lower plate 33 is fitted into the concave portion 23 of the inner lid 20, whereby the inner lid 20 can be covered in a sealed state by the lid device 30.

< embodiment 2 >

Next, a wet tissue heater according to embodiment 2 will be described with reference to fig. 14 to 18.

In embodiment 2 shown in fig. 14 to 18, the same portions as those in embodiment 1 shown in fig. 1A to 13 are given the same reference numerals, and detailed description thereof is omitted.

As shown in fig. 14, 15, and 17, the wet tissue heater 1 includes: a synthetic resin container body 10 having a side wall 11 including 4 side surfaces and a bottom surface 12, and having an upper opening 10a formed above the side wall 11; an inner lid 20 made of synthetic resin, openably and closably provided in the container body 10, closing an upper opening 10a of the container body 10, and having a take-out port 21 for the wet tissue 2; a lid device 30 openably and closably provided in the container body 10 and covering the inner lid 20 for closing the container body 10; a synthetic resin push-up plate 40 is disposed in the container body 10 and pushes up the wet tissue storage body 2A.

stopper mechanisms

springs

9a and 9b provided on the swing axis of the container body 10.

Next, the cover device 30 will be described with reference to fig. 14 and 15. The cover device 30 has a lower plate 33, an upper plate 34, and a side plate 35 between the lower plate 33 and the upper plate 34, and a heating mechanism 36A for heating the wet tissue 2 via the lower plate 33 is disposed in the space 30a of the cover device 30.

The lower plate 33 of the lid device 30 has a convex portion 33a protruding toward the container body 10. The heating mechanism 36A incorporated in the cover device 30 has the same structure as the heating mechanism 36A shown in embodiment 1, and the lower plate 33 has a convex portion 33 a. Since the heating mechanism 36A is disposed inside the convex portion 33a, the heating mechanism 36A is positioned on the container body 10 side (see fig. 4B and 4C). The heating mechanism 36A of the lid device 30 is connected to a collective wiring line 37d extending into the container body 10, and the collective wiring line 37d is connected to a wiring line 86 connected to the container body 10 via a connection portion 85 (see fig. 18).

As described above, the inner surfaces of the side surfaces 11a and 11b facing each other of the side walls 11 of the container body 10 are provided with a pair of

stopper mechanisms

50 and 50 for locking the push-up plate 40. The pair of

stopper mechanisms

50, 50 are provided along the inner surfaces of the side surfaces 11a, 11B of the container body 10, but the pair of stopper mechanisms 50, the push-up plate 40, and the locking structure of the pair of

stopper mechanisms

50, 50 and the push-up plate 40 are substantially the same as the structure of embodiment 1 shown in fig. 5 to 10B.

Next, the internal structure of the container body 10 will be described with reference to fig. 16. As shown in fig. 16, a spring housing wall 14 for housing one end of the metal spring 5 is provided on the bottom surface 12 of the container body 10. The spring housing wall 14 is formed intermittently, and moisture discharge openings 14a are provided at predetermined intervals in the spring housing wall 14. It is considered that since the wet wipe 2 releases moisture from the inside in use, moisture from the wet wipe 2 accumulates on the bottom surface 12, particularly on the region 12A surrounded by the spring housing wall 14.

In the present embodiment, the region 12A of the bottom surface 12 surrounded by the spring housing wall 14 rises upward relative to the other region 12B, and gradually falls from the region 12A toward the other region 12B.

Therefore, the moisture accumulated in the region 12A surrounded by the spring housing wall 14 in the bottom surface 12 from the wet wipe 2 can be efficiently discharged to the region 12B other than the region 12A via the moisture discharge opening 14 a.

Although one end of the metal spring 5 is housed in the spring housing wall 14 of the bottom surface 12, moisture can be effectively discharged from the region 12A surrounded by the spring housing wall 14 to the other region 12B, and therefore the spring 5 is not corroded or deteriorated by moisture.

An auxiliary rib 11e extending in the vertical direction is provided on the inner surface of the side wall 11 of the container body 10, and the auxiliary rib 11e engages with the guide groove 42 of the push-up plate 40 (see fig. 5 and 6).

claws

52a and 53a of the

stopper holder

52 and 53 project in parallel to the side surfaces 11a and 11b of the container body 10. Therefore, the stopper mechanism 50 can be configured as thin as possible, and therefore the amount of protrusion of the stopper mechanism 50 into the container body 10 can be suppressed.

Furthermore, since the

claws

52a and 53a is also reduced, and the engagement between the

claws

A spring housing wall (push-up plate urging mechanism housing wall) 14 that houses one end of the spring 5 is provided on the bottom surface 12 of the container body 10, and a region 12A of the bottom surface 12 surrounded by the spring housing wall 14 is raised upward relative to the other region 12B. Therefore, even if the moisture released from the wet wipe 2 accumulates in the area 12A in the spring housing wall 14 in the bottom surface 12, the moisture can be discharged from the area 12A to the other area 12B via the moisture discharge opening 14 a. Therefore, the spring 5 housed in the spring housing wall 14 is not corroded or deteriorated.

The lower plate 33 of the lid device 30 has a protrusion 33a protruding downward, and the space 30a inside the lid device 30 can be obtained more widely by the protrusion 33 a. Further, since lower plate 33 has convex portion 33a protruding downward toward container body 10, heating mechanism 36A is disposed inside convex portion 33 a. Therefore, the heating mechanism 36A in the cover device 30 can be moved further toward the upper push plate 40 by the convex portion 33 a. Thus, the wet tissue storage body 2A can be efficiently heated while the wet tissue storage body 2A is pressed between the convex portion 33a of the lower plate 33 and the push plate 40 by the force of the spring 5 by the heating mechanism 36A located on the push plate 40 side. Further, by providing the convex portion 33a in the lower plate 33, the space between the heating mechanism 36A and the upper plate 34 can be obtained more widely, and the heat insulator 39 having a large thickness can be disposed between the heating mechanism 36A and the upper plate 34. This can effectively prevent heat from the heating mechanism 36A from being transmitted to the upper plate 34 side. Further, the concave portion 23 into which the convex portion 33a of the lower plate 33 enters is formed in the inner lid 20, and the convex portion 33a of the lower plate 33 is fitted into the concave portion 23 of the inner lid 20, whereby the inner lid 20 can be covered in a sealed state by the lid device 30.
