Hereinafter, a wet sheet heating container according to an embodiment of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated example.

[Configuration of wet sheet heating container 100]
As shown in FIGS. 1 to 3, the wet sheet heating container 100 according to the present embodiment has, for example, an opening 11, and the wet sheet P in a rolled state is stored from the opening 11. And a lid body 20 detachably attached to the container body 10 so as to open and close the opening 11, and having a take-out portion 21 for taking out the wet sheet P to the outside on the upper surface. Is configured.
The rolled wet sheet P to be stored in the storage container 100 is perforated at regular intervals in the length direction, and the wet sheet P of a size cut along the perforation is used. It is designed to be used by users.

The container body 10 has a substantially cylindrical shape that is substantially constant from the bottom to the vicinity of the upper end, and has a large opening 11 on the upper surface. Further, on the outer peripheral surface of the upper end portion of the container body 10, a male screw portion is formed along the circumferential direction.
Since the container body 10 has a cylindrical shape, the roll-shaped wet sheet P can be arranged and housed in a substantially concentric position. In addition, the wet sheet P is configured such that a piece of paper is fed from the center side of the roll.
The container body 10 is integrally formed by injection molding, two-color molding, blow molding or the like using, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS (Acrylonitrile Butadiene Styrene) resin, or the like. Is formed in.

The lid 20 has a cylindrical shape having a shorter length than the container body 10, and its upper end is closed by the top surface portion 22 and its lower end is open. Further, the lid body 20 has an outer diameter substantially equal to the outer diameter of the container body 10, and a female screw portion that is screwed into the male screw portion of the container body 10 is formed on the inner peripheral surface thereof. The lid 20 is attachable to and detachable from the upper end of the container body 10 by the female screw portion.
Therefore, the wet sheet P can be filled inside the container body 10 with the lid body 20 removed from the container body 10, and the roll of the wet sheet P inside can be filled with the lid body 20 attached to the container body 10. It is possible to hold it so that it does not go out.
The lid 20 is integrally formed by injection molding, two-color molding, blow molding or the like using PE, PP, PET, ABS resin or the like, for example.

A recess 23 is formed in the center of the top surface portion 22 of the lid body 20, and a small lid 25 is attached to the top surface portion 22 so as to fit into the recess portion 23.
Further, a cylindrical portion 24 is provided upright in the center of the recess 23, and the inside thereof penetrates vertically to form the take-out portion 21. At the upper end of the cylindrical portion 24, a flange-shaped locking portion 24a protruding outward is formed, which enables locking when the small lid 25 is closed.

Here, the take-out part 21 is for taking out the wet sheet P inside with the lid 20 attached to the container body 10.
The take-out portion 21 is formed by, for example, a cross-shaped cut in a plan view, and when the wet sheet P passes through the center of the wet sheet P in an upward direction, it gives a proper sliding resistance to the wet sheet P. ing. As a result, when the wet sheet P is used, its sliding resistance acts on the wet sheet P to promote separation from the perforations, and the leading edge of the next wet sheet P is held in a state of being sandwiched by the take-out portion 21. As a result, returning to the container body 10 is prevented, and the next wet sheet P can be used immediately.
The take-out portion 21 is opened and closed by rotating the small lid 25 around the Y axis. The small lid 25 is provided with a hinge portion (not shown) that allows the small lid 25 to be bent along the Y-axis direction near the rear end thereof, and is fitted into the recess 23 to close the take-out portion 21. It is possible to rotate from the state up to the state where the take-out portion 21 is opened. The small lid 25 is normally closed except that it is opened when the wet sheet P is taken out.

A heater chamber 12 that accommodates a heater 31 that generates heat is provided at the center of the bottom of the container body 10 and is partitioned from a wet sheet accommodation chamber 13 that accommodates the wet sheet P. The heater 31 generates heat by supplying power from a power cord, a rechargeable battery or the like (not shown).
In addition, a heat insulating material is provided around the heater 31 as necessary to prevent hot air from being sent to the wet sheet storage chamber 13. This is to prevent volatilization of the wet sheet P when it contains a volatile component.

A support 32 of the heat source film 33 is rotatably supported at the center of the bottom of the wet sheet storage chamber 13. The support column 32 is formed of a metal having a high thermal conductivity, such as copper, aluminum, or chromium, and conducts the heat generated by the heater 31 to the heat source film 33.

The heat source film 33 is a film-shaped member that functions as a heat source by releasing the heat transmitted through the support columns 32. The heat source film 33 is non-detachably attached to the pillar 32, and radiates (radiates) heat conducted from the heater 31 through the pillar 32 to the outside. As shown in FIG. 4, the heat source film 33 is wound around the support column 32 in a roll shape, in order from the innermost layer, the first heat radiation resin layer 331, the heat conductive metal layer 332, and the second heat radiation resin layer 332. The heat dissipation resin layer 333 has a three-layer structure.
The first heat-dissipating resin layer 331 and the second heat-dissipating resin layer 333 are formed of, for example, a material having excellent heat-dissipating properties such as graphite and acrylic resin, so that the heat-conducting metal layer 332 serving as a heat source is not exposed. It is configured to cover the entire surface of the heat conductive metal layer 332. The first heat-dissipating resin layer 331 and the second heat-dissipating resin layer 333 may be made of the same material or different materials as long as they have excellent heat dissipation.
The heat conductive metal layer 332 is formed of, for example, a metal having a high heat conductivity such as copper, aluminum, or chrome, and the heat conducted from the heater 31 through the support column 32 is passed through the second heat radiating resin layer 333. And release it to the outside. Then, the heat emitted from the heat source film 33 heats the central portion (core portion) of the wet sheet P.
That is, the heater 31 functions as the heating unit of the present invention.
From the viewpoint of efficient heating, the heat source film 33 is preferably formed to have a height corresponding to the height of the wet sheet P to be stored, and most preferably has the same height.

The heat source film 33 is wound around the support column 32 in a roll by rotating the support column 32 in a predetermined direction (first direction).
An auxiliary jig 34 is provided on the upper part of the support column 32 to assist the work of winding the heat source film 33 and to urge the heat source film 33 after winding from the surface to prevent the heat source film 33 from spreading outward. It is installed. The auxiliary jig 34 is made of, for example, a chemical-resistant/heat-resistant material having a low thermal conductivity.
As shown in FIG. 5, a fitting groove 341 capable of fitting the tip of the support column 32 is provided on the back surface on the upper end side of the auxiliary jig 34, and the tip of the support column 32 is fitted into the fitting groove 341. By combining them, the auxiliary jig 34 can be attached to the support column 32.
The auxiliary jig 34 also includes an opening/closing portion 342 that can be opened and closed like an umbrella. The opening/closing part 342 opens the bias against the heat source film 33 when the heat source film 33 wound around the support column 32 is biased to keep the shape of the heat source film 33 (see FIG. 1 etc.). It is configured to be able to switch between the open state (see FIG. 3 etc.).
Further, the opening/closing part 342 is formed with a plurality of slits 343 capable of holding the wet sheet P, and the wet sheet P can be held in any one of the plurality of slits 343.

Here, a method of storing the wet sheet P in the container body 10 (wet sheet storage chamber 13) will be described.
First, the worker rotates the auxiliary jig 34 in a predetermined direction (first direction) with the auxiliary jig 34 attached to the support column 32. Accordingly, the support column 32 can be rotated in a predetermined direction in conjunction with the auxiliary jig 34, and thus the heat source film 33 can be wound around the support column 32.
Next, the worker suppresses the outward spreading of the heat source film 33 by closing the auxiliary jig 34 (closed state) so as to urge the heat source film 33 after winding from the surface. (See Figure 1).
Next, the worker stores the wet sheet P in the container body 10 by inserting the central portion (core portion) of the roll-shaped heat sheet P into the heat source film 33 wound in the roll shape. As a result, the heat source film 33 is positioned inside the core of the wet sheet P when the wet sheet P is stored, and the wet sheet P is heated from the core side. Therefore, since the wet sheet P can be efficiently heated by the amount used by the worker, the wet sheet P can be heated without drying the wet sheet P and without reducing the effect of the chemical liquid, and the wet sheet P can be kept in a quality-assured state. Can be provided.
Next, the worker pulls out the tip of the wet sheet P while sandwiching the tip of the wet sheet P in one of the slits 343 of the auxiliary jig 34, inserts the take-out portion 21 of the lid 20, and inserts the lid 20. Is attached to the container body 10. As a result, the front end portion of the wet sheet P is held in a state of being sandwiched between the takeout portions 21, and the wet sheet P can be used immediately.

When the operator pulls out the front end of the wet sheet P, the auxiliary jig 34 is opened in the closed state (that is, switched to the open state) by the force that pulls out the wet sheet P against the biasing force. , Rotates in the direction opposite to the predetermined direction (second direction). As a result, the support column 32 rotates in the direction opposite to the predetermined direction in conjunction with the auxiliary jig 34, so that the heat source film 33 spreads outward according to the inner diameter of the roll of the wet sheet P (see FIG. 3 ). Since the inner diameter of the roll of the wet sheet P increases as the wet sheet P is used, the heat source film 33 also spreads outward as the inner diameter of the roll increases as the number of the wet sheets P decreases (FIG. 6). reference). Therefore, since the heat source film 33 can be brought close to the wet sheet P, the wet sheet P can be efficiently heated.

As described above, according to the wet sheet heating container 100 according to the present embodiment, the container body 10 is pivotally supported by the container body 10 and is positioned inside the core portion of the wet seat P when the wet sheet P is stored. And a heat source film 33 that can be wound around the support column 32 in a roll according to the rotation of the support column 32 in the first direction, and a heating unit (heater 31) that indirectly heats the heat source film 33. Prepare
Therefore, according to the wet sheet heating container 100 according to the present embodiment, it is possible to efficiently heat the wet sheet P by the amount used by the operator, and therefore the wet sheet P is not dried and the effect of the chemical solution is obtained. It is possible to provide the wet sheet P in a state in which the quality is ensured without lowering the quality. Further, since the heater 31 is arranged at a position that does not hinder the taking out of the next wet sheet P, the ease of taking out the wet sheet P can be ensured. In addition, since the columns 32 and the heat source film 33 are arranged in the core of the wet sheet P, it is possible to prevent the container from increasing in size, and ensure portability to the outside and storability in the room.

Further, according to the wet sheet heating container 100 according to the present embodiment, the heat source film 33 has a surface facing the wet sheet P made of a heat radiating material in a state where the heat source film 33 is wound around the support column 32 in a roll shape. It
Therefore, according to the wet sheet heating container 100 according to the present embodiment, heat can be efficiently transferred to the wet sheet P, so that the heating efficiency of the wet sheet P can be improved and the wet sheet P can be improved. It is possible to reduce the power cost while guaranteeing the quality.

In addition, the wet sheet heating container 100 according to the present embodiment includes an auxiliary jig 34 that can be attached to the upper part of the support column 32. Further, the auxiliary jig 34 is in a closed state in which the heat source film 33 wound around the support column 32 is biased to maintain the shape of the heat source film 33, and in an open state in which the bias to the heat source film 33 is released. And an opening/closing unit 342 capable of switching between and. Further, the opening/closing part 342 is formed with a plurality of slits 343 capable of sandwiching the wet sheet P. Further, when the wet sheet P is pulled out while the wet sheet P is sandwiched by the slits 343, the auxiliary jig 34 rotates in the second direction that is the opposite direction to the first direction.
Therefore, according to the wet sheet heating container 100 according to the present embodiment, the work of storing the wet sheet P can be performed easily and safely, so that the work load on the worker can be reduced.

Further, according to the wet sheet heating container 100 according to the present embodiment, the heat source film 33 is formed to have the same height as the height of the wet sheet P.
Therefore, according to the wet sheet heating container 100 according to the present embodiment, uneven heating of the wet sheet P can be suppressed, so that the usability during use of the wet sheet P can be improved.

The specific description has been given above based on the embodiment according to the present invention, but the present invention is not limited to the above-described embodiment, and can be modified without departing from the gist thereof.

For example, in the above embodiment, the configuration in which the heater 31 is provided has been described as an example, but the configuration is not limited to this. For example, instead of providing the heater 31, the support column 32 may function as a heater (heating unit).
This eliminates the need to secure a space (heater chamber 12) in which the heater 31 is provided, which makes it possible to reduce the size of the container and more surely secure portability to the outside and storability in the room. be able to.

Instead of providing the heater 31, a so-called film heater may be used in which the heat source film 33 is directly heated by passing an electric current through the heat conductive metal layer 332 in the heat source film 33. In this case, the wiring for passing an electric current through the heat conductive metal layer 332 may be provided on the lower end side of the heat source film 33.
Thereby, the temperature of the heat source film 33 can be directly controlled, so that the quality of the wet sheet P can be further secured.

Further, in the above embodiment, the configuration in which the auxiliary jig 34 is provided has been described as an example, but the configuration is not limited to this. That is, the auxiliary jig 34 may not be provided. In this case, when the heat source film 33 is wound up, it is preferable that the tip end of the support column 32 is rotated by fingers so that the wet sheet P is stored with the heat source film 33 wound up. After the wet sheet P is stored, due to the elasticity of the heat source film 33, the heat source film 33 naturally expands outward according to the inner diameter of the roll of the wet sheet P.
By forming the upper end portion of the support column 33 with a material having a low thermal conductivity, the support column 33 can be safely rotated even when the worker performs the work of storing the wet sheet P while the heater 31 is operating. You can Therefore, when adopting the configuration in which the auxiliary jig 34 is not provided, it is preferable to form the upper end portion of the support column 33 with a material having a low thermal conductivity.

In the above embodiment, the heat source film 33 has a three-layer structure including the first heat dissipation resin layer 331, the heat conductive metal layer 332, and the second heat dissipation resin layer 333 in order from the innermost layer. Although the configuration is described as an example, the configuration is not limited to this. For example, as shown in FIG. 7, instead of the heat-conductive metal layer 332, a heat-conductive metal wire 334 made of a metal having a high heat conductivity such as copper, aluminum, or chrome is attached to the first heat-radiating resin layer 331 and It may be configured to be sandwiched between the second heat radiation resin layers 333.
Further, the heat source film 33 does not necessarily have a three-layer structure, and may be one layer or two layers as long as the heat conducted from the heater 31 via the support column 32 can be discharged to the outside. There may be four layers or more.

Further, in the above-described embodiment, the configuration in which the first heat-dissipating resin layer 331 made of a heat-dissipating material is provided as the innermost layer in the state of being wound in a roll around the support column 32 is described as an example. , But is not limited to this. That is, the innermost layer in a state of being wound in a roll around the support column 32 may have any configuration as long as the heating efficiency of the heat source film 33 can be improved, for example, the first heat radiation resin layer. Instead of 331, a heat insulating layer formed of a material such as a heat insulating material that does not release heat may be provided.
Even when the innermost layer is formed of the first heat-dissipating resin layer 331 as in the embodiment, the heat radiated from the first heat-dissipating resin layer 331 may be dissipated to a portion other than the wet sheet P. Since the heat radiation from the first heat radiation resin layer 331 is added to the heat radiation from the second heat radiation resin layer 333, the temperature of the heat source film 33 can be transferred to the wet sheet P earlier. Become.

In addition, the detailed configuration of the wet sheet heating container 100 can be appropriately changed without departing from the spirit of the present invention.
