TECHNICAL FIELD OF THE INVENTION
The present invention relates to a warmer for keeping food containers such as cans and bottles, such as canned tea or coffee, canned green tea, and other types of canned tea and bottles.
[0002]
[Prior art]
Some containers such as cans and bottles containing food and drinks sold at vending machines and stores are sold in a warm state according to the type of food and drink. However, there is a problem that such food and drink are cooled down in a short time together with the container after purchase.
[0003]
In addition, there is no simple heating means for products sold at a normal temperature or a cooled state instead of the warmed state, so that there is a problem that it is not possible to eat and drink in the warmed state.
[0004]
[Problems to be solved by the invention]
In this regard, insulated bags have been provided for keeping food containers warm. However, even though the heat retention time can be extended for a while, the heat retention state cannot be maintained for a long time.
[0005]
For this reason, it has been desired to provide a warmer provided with a heat source, but there are various problems to be solved in order to provide a portable warmer. For example, when an electric heater is used as a heat source, there is a problem that battery power is consumed in a short time. On the other hand, when a thermal heater that burns fuel is used as a heat source, there is a problem that there is a risk of fire.
[0006]
By the way, it is advantageous that the present inventor adopts, as a heat source of the incubator, a catalyst heater that generates an oxidative exothermic reaction when a reactant is passed in a vaporized state with respect to a heating body provided with a catalyst on the surface. Was found. Such a catalyst heater is known per se, for example, as used in a mosquito catcher disclosed in Japanese Patent Publication No. 1-15248 and a stove disclosed in JP-A-2000-51086.
[0007]
However, according to experiments performed by the present inventor, the following various problems were found when such a catalyst heater was used as a heat source for a warmer of a food and drink container.
(1) When providing a warmer that keeps a food or drink container such as a can or a bottle in a warm state, it is desirable to configure a tubular container body having an upper opening shape into which the food and drink container can be removably inserted. However, when the bottom of the beverage container is heated by installing a catalyst heater in such a container body, the catalyst heater is disposed in a substantially closed space, so that the vaporization efficiency of the reactant and the passage efficiency to the catalyst are reduced. Bad, sufficient oxidation heat cannot be obtained. Therefore, there is a problem to be solved in this respect.
(2) When the food and drink container is heated, water droplets are generated due to dew condensation, and the water droplets drop from the bottom. When water droplets adhere to the surface of the catalyst heater, the oxidative heat generation reaction is hindered, so that necessary heat generation cannot be obtained. Therefore, there is a problem that such a problem must be solved.
(3) In order to improve the vaporization efficiency of the reactant and the passage efficiency to the catalyst, it is desirable to provide an air introduction hole on the peripheral surface of the cylindrical container body located below the catalyst heater. If a strong cross wind is applied when the vessel is used outdoors, the vaporized gas of the reactant is blown off sideways, and the required heat generated by the catalyst heater cannot be obtained. Therefore, there is a problem to be solved such a problem.
(4) In addition, it is desirable that the heat insulator can be used in a vehicle such as a car by a consumer, and it is required that the heat insulator be held in a proper position in the car. is there.
[0008]
[Means for Solving the Problems]
Therefore, the present invention is configured as a means that a tubular container body having an upper opening shape into which a food container such as a can or a bottle is removably inserted, and a support for supporting a bottom portion of the food container inside the container body. A guide plate and a warmer, comprising a catalyst heater provided below the supporting guide plate, and configured to form a ventilation gap between the outer peripheral surface of the eating and drinking container and the inner peripheral surface of the container body, The catalyst heater is a cassette container that holds a heating element having at least a plurality of through-holes provided with a catalyst on the surface in a vertically penetrating manner, and a reactant that causes an oxidative exothermic reaction by the catalyst when passing through the heating element in a vaporized state. The support guide plate is formed of a heat conductive plate, and has a support plate portion that supports the bottom of the food and drink container, and a guide groove portion that is recessed downward from the support plate portion and extends diametrically. And which, from the heating of the catalyst heater to the point comprising brought forming a hot air passage leading to the vent gap through said guide groove. According to various embodiments added to the present invention, the above-described problems can be completely solved.

The heating element 3 is fixed to the window 16 with the fixing means 22 including fixing means 22 such as a caulking fixing means with a penetrating caulking hole or a shaft attaching means such as a rivet.
[0013]
As shown in FIG. 2B, the guide sleeve 4 forms a cylindrical portion 24 having a storage chamber 23 in which the heating element 3 can be inserted from above, and the insertion piece 21 is attached to an upper flange 25 of the cylindrical portion 24. , 21 are provided. A large number of rib-like irregularities 27 extending in the vertical direction are formed on the inner peripheral wall of the storage chamber 23, and a large number of small holes 28 penetrating inside and outside are formed on the peripheral surface of the cylindrical portion 24.
[0014]
The moisture absorbing sheet 29 shown in FIG. 2B is made of nonwoven fabric or paper, and can be placed on the groove bottom of the guide groove 15 in the support guide plate 2.
[0015]
The heating element 3 to which the support guide plate 2 is fixed via the holding plate 17 is shown in FIG. 3 by inserting the insertion pieces 21, 21 of the holding plate 17 into the insertion holes 26, 26 of the guide sleeve 4. As described above, the heating element 3 is integrated with the guide sleeve 4 in a state of being stored in the storage chamber 23. In this state, the guide sleeve 4 is inserted into the holding tube 5, and the lower end edge of the holding tube 5 is fitted to the unit plate 6, and includes the cassette container 7 which is detachable from the unit plate 6, and constitutes the catalyst heater unit 30. I do.
[0016]
In the case of the example shown in the drawing, the ear 31 provided on the outer peripheral surface of the guide sleeve 4 is configured to be fitted into the notch 32 of the holding cylinder 5 with the guide sleeve 4 inserted into the holding cylinder 5. The lower flange 33 of the guide sleeve 4 inserted from the lower end of the cylinder 5 is detachably fitted to the peripheral edge of the center hole 34 of the unit plate 6.
[0017]
The unit plate 6 is formed in a substantially annular shape, forms a rib 35 extending concentrically with the center hole 34, and forms detachable holes 36, 36 arranged diametrically opposite to the rib 35 so as to face the rib 35. An inclined surface 37 is formed on the upper surface of the rib 35 near the attachment / detachment holes 36, 36. On the other hand, the cassette container 7 is provided with an open rim 38 facing the center hole 34, and is inserted around the open rim 38 in the detachable holes 36, 36 so as to be able to be inserted and removed. Substantially L-shaped hooks 39, 39 are erected. Accordingly, when the cassette container 7 is normally rotated around the axis with the hooks 39, 39 inserted into the attachment / detachment holes 36, 36, the hooks 39, 39 rise along the inclined surface 37 of the rib 35. The cassette container 7 is fixed to the unit plate 6 so as not to be detachable, and the open rim 38 communicates with the storage chamber 23 of the guide sleeve 4. In this state, when the cassette container 7 is reversed around the axis, the hooks 39, 39 descend along the inclined surface 37 of the rib 35 and escape from the attachment / detachment holes 36, 36. 6 can be removed freely. Incidentally, a large number of through holes 40 are formed in the annular portion of the unit plate 6.
[0018]
The cassette container 7 contains a reactant 41 such as alcohol inside. For example, the sponge body provided inside is impregnated with liquid alcohol, and is opened by a cap 7a as shown in FIG. 1 during storage. The lip 38 is sealed. Although not shown, a portable storage container for storing a reactant composed of liquid alcohol is prepared, and when the reactant 41 in the cassette container 7 becomes insufficient, the storage container may be emptied from the storage container. It is possible to replenish the reactants.
[0019]
As shown in FIG. 4, the catalyst heater unit 30 configured as described above is inserted into the inside of the container body 1 from the bottom opening, and is fixed by the fixing ring 9. That is, when the screw portion 8 of the fixing ring 9 is screwed into the bottom opening edge of the container body 1, the peripheral edge of the unit plate 6 is sandwiched between the fixing ring 9 and the inner peripheral step 42 of the container body 1.
[0020]
As shown in FIGS. 1 and 4, the container body 1 has a wide-open portion 43 near the upper end including the upper opening, and the inner diameter and the outer diameter are enlarged by the wide-open portion 43. When the eating and drinking container 44 is inserted into the container main body 1 from the upper opening, the eating and drinking container 44 is supported at the bottom by the support guide plate 2, and in this state, the outer peripheral surface of the eating and drinking container 44 and the inner peripheral surface of the container main body 1 meet. A sufficient ventilation gap 45 is formed therebetween. An air introduction hole 46 is formed in the vicinity of the bottom opening edge of the container body 1, that is, in the peripheral wall portion located below the support guide plate 2. In the case of the example shown in the drawings, the air introduction holes 46 which are elongated in the circumferential direction of the container body 1 are shown, but the air introduction holes 46 may be formed by arranging small holes in the circumferential direction of the container body 1. good.
[0021]
FIG. 5 shows the operation of the warmer according to the above embodiment. The reactant 41 contained in the cassette container 7 is vaporized and rises from the open rim 38 toward the storage chamber 23 of the guide sleeve 4 as shown by the arrow F1 in the drawing, and passes through the heater 3. At this time, the gas in the vaporized state generates an oxidative exothermic reaction by the catalyst of the heating element 3 and rises as hot air. The rising hot air is blocked from rising by the bottom of the food and drink container 44. However, since the supporting guide plate 2 is provided with the guide groove portion 15, as shown by the arrow F2 in the drawing, the diametrical direction is along the guide groove portion 15. To form a hot air passage 47 reaching the ventilation gap 45, and generate a hot air flow 47a rising in the ventilation gap 45 as shown by the arrow F3 in the figure. Therefore, since the hot air is well discharged from the upper opening of the container body 1, the vaporization of the reactant 41 from the cassette container 7 is promoted, and the catalyst heater unit 30 is almost closed inside the container body 1. Nevertheless, it is possible to perform heating by a favorable oxidation exothermic reaction.
[0022]
In the illustrated example, the guide groove 15 of the support guide plate 2 is disposed above the upper surface of the heater 3 by a distance S, so that the hot air immediately after passing through the heater 3 is transferred to the lower surface of the support guide plate 2. , And ascends through a large number of through holes 13 of the support guide plate 2 as shown by the arrow F4 in the drawing, and joins the hot air flow 47a. Further, the hot air that has entered the guide groove 15 as described above also spreads toward the lower surface of the support plate 14 via the through hole 13 provided on the side wall of the guide groove 15, and the through hole 13 of the support plate 14 is And joins the hot air flow 47a. Therefore, the hot air flow 47a is formed over the entire peripheral surface of the food and drink container 44, and heats and maintains the food and drink container 44 from the outer periphery. In addition, since the support guide plate 2 is heated together with the heating element 3, the bottom of the food and drink container 44 is heated and kept warm.
[0023]
The vaporization of the reactant 41 from the cassette container 7 is promoted by taking in external air into the container body 1. As shown by an arrow A1 in FIG. 5, the air that has entered from the air introduction hole 46 passes through the through hole 13 of the support guide plate 2 and flows toward the hot air flow 47a. Further, the air that has entered from around the cassette container 7 as indicated by the arrow A2 in the figure rises through the through hole 40 of the unit plate 6 and flows toward the hot air flow 47a through the through hole 13 of the support guide plate 2. Exit. In this manner, the flow of hot air toward the upper opening of the container body 1 is promoted, and as a result, the storage chamber 23 of the guide sleeve 4 is sucked and made negative pressure, and air is released from the many small holes 28 provided in the guide sleeve 4. Since it is retracted, the vaporization of the reactant 41 from the cassette container 7 is promoted.
[0024]
At this time, if the food and drink container 44 is not pre-heated, dew condensation occurs at the beginning when the food and drink container 44 is heated by the catalyst heater unit 30. Such dew drops as drops of water. Water drops that drop toward the support plate portion 14 of the support guide plate 2 fall down through the through holes 13 and are discharged. The water droplets dripping toward the guide groove 15 are absorbed by the moisture absorbing sheet 29, and are prevented from entering the heating element 3. When the moisture-absorbing sheet 29 is formed of a material having excellent air permeability, the sheet may cover the upper portion of the heating element 3 as shown in FIG. 3. As shown in the drawing, the heating element 3 may be divided so as to open the upper part.
[0025]
By the way, when using a warmer outdoors such as a seaside zone or a forest zone, when a strong crosswind is received, the gas volume and the amount of air entering from the air introduction hole 46 are strong, so that the gas vaporized from the reactant 41 is generated. It is blown off, making it difficult for the catalyst heater unit 30 to generate heat as intended. In this case, the user may use the warmer with the protection ring 10 attached to the container body 1.
[0026]
As shown in FIG. 1, the protection ring 10 includes a ring portion 48 that is externally inserted into the wide mouth portion 43 of the container body 1, and a lower end edge of the ring portion 48 that is adapted to a lower step portion 43 a of the wide mouth portion 43. An orientation flange 49 is provided, and is configured to be vertically slidable along the outer peripheral surface of the container body 1. An engaging / disengaging means for holding the protection ring 10 in a state of being positioned on the outer periphery of the wide-open portion 43 is provided. In the case of the example shown in the figure, an escape groove 50a extending upward from the lower end step of the wide-open portion 43 and the escape groove 50a are provided. An engaging and disengaging means is constituted by an approximately L-shaped groove means 50 having a locking groove 50b extending in the circumferential direction from the groove 50a, and a projection 51 projecting from the inner peripheral surface of the protective ring 10 and fitted into the groove means 50. are doing. Therefore, as shown in FIG. 6A, the protection ring 10 can be held on the outer periphery of the wide mouth portion 43 with the projection 51 locked in the locking groove 50a. When the protection ring 10 is rotated and the projection 51 is positioned in the escape groove 50a, the protection ring 10 descends along the container body 1 as shown in FIG. 46 can be shielded from the outside. The inward flange 49 of the protection ring 10 is formed so as to have an inner diameter along the outer peripheral surface of the cylindrical portion lower than the wide mouth portion 43 of the container body 1, and thus guides the protection ring 10 to slide vertically. At the same time, a gap 52 is formed between the ring portion 48 and the outer peripheral surface of the container body 1. Accordingly, as indicated by an arrow A3 in FIG. 6B, of the crosswinds received from the outside, only the air that detours and enters the gap 52 is allowed to pass through the air introduction hole 46. Therefore, the airflow and the airflow of the air entering the catalyst heater unit 30 housed in the container body 1 are controlled, and the oxidation exothermic reaction of the catalyst heater unit 30 in outdoor use is set to the optimal condition. In order to return the protection ring 10 to the original state as shown in FIG. 6A, the protection ring 10 is lifted along the container body 1, the projection 51 is inserted into the escape groove 50a, and then the protection ring 10 is removed. By rotating in the direction opposite to the arrow R, the protrusion 51 may be fitted into the locking groove 50b. Note that the raised position and the lowered position of the protection ring 10 are indicated by chain lines in FIG. 4 in addition to FIGS. 6A and 6B.
[0027]
In order to enable the heat retaining container in a vehicle such as an automobile, a hanging holder 11 and / or a mounting holder 12 are prepared as an attachment.
[0028]
As shown in FIG. 1, the holding holder 11 has a holding ring 53 having an inner diameter along the outer peripheral surface of a cylindrical portion lower than the wide-mouthed portion 43 of the container body 1, and is protruded from the holding ring 53. And holding claw means 55 detachably attached to the bracket 54. Therefore, as shown in the right column of FIG. 7, the holding ring 53 is externally inserted from the lower end of the container main body 1, and the holding ring 53 is attached to the holding ring 53 while being locked to the lower step 43 a of the wide opening 43. The claw means 55 can be removably inserted into and removed from a louver at an air-conditioner outlet of an automobile or the like. That is, since the holding ring 53 is fixed by inserting the holding claw means 55 into the louver of the air conditioner outlet, the container main body 1 can be held in the holding ring 53 so as to be freely inserted and removed. Then, the food and drink container 44 such as the can 44a and the bottle 44b can be inserted into and removed from the container body 1 held by the holding ring 53. Since the cassette container 7 is detachable from below the container main body 1 as shown in the figure, the reagent can be supplied at any time.
[0029]
The mounting holder 12 is composed of a cylindrical body 57 provided with a screw portion 56 as shown in FIG. As is well known, a so-called cup holder composed of a tube receiving member is provided in the room of a vehicle such as an automobile, and the inner diameter of the cup holder is designed according to the outer diameter of the can 44a and the bottle 44b. For this reason, the container body 1 having a large diameter so as to form the ventilation gap 45 with respect to the food and drink container 44 as in the present invention cannot be inserted into the cup holder. For this reason, the cylindrical body 57 constituting the mounting holder 12 is formed to have substantially the same diameter as the can 44a and the bottle 44b so that it can be inserted into the cup holder, and is detachably attached to the lower part of the unit plate 6. Be attached. In the case of the illustrated example, as shown by a chain line in FIG. 4, the screw holder 56 is detachably screwed to a screw cylinder part 58 protruding from the lower side of the unit plate 6, so that the mounting holder 12 is mounted. Is fixed to the container body 1 and protrudes downward from the container body 1. However, the mounting holder 12 may be configured to be attached to and detached from the fixing ring 9. In this manner, as shown in the left column of FIG. 7, the mounting holder 12 projecting from below the container body 1 can be inserted into the cup holder, and the held container body 1 can be A food and drink container 44 such as a bottle 44a and a bottle 44b can be inserted and removed. Since the cassette container 7 is detachable from below the container main body 1 as shown in the figure, the reagent can be supplied at any time.
[0030]
Needless to say, the present invention is not limited to the configuration of the above embodiment, and various design changes are possible. Further, it is convenient to provide a bag, a bag, a case, or the like for carrying the warmer of the present invention.
[0031]
【The invention's effect】
The present invention provides a tubular container body 1 having an upper opening shape into which a food container 44 such as a can 44a or a bottle 44b is removably inserted, and a support for supporting a bottom portion of the food container 44 inside the container body 1. It consists of the guide plate 2 and the catalyst heater 30 provided below the support guide plate 2, and is configured such that a ventilation gap 45 is formed between the outer peripheral surface of the eating and drinking container 44 and the inner peripheral surface of the container main body 1. The catalyst heater 30 includes a heater 3 having at least a plurality of through-holes provided with a catalyst on its surface formed in a vertically penetrating manner, and an oxidizing heat generated by the catalyst when passing through the heater 3 in a vaporized state. The supporting guide plate 2 is constituted by a heat conductive plate, and supports the bottom of the eating and drinking container 44; Recessed downward And a guide groove 15 extending in the diametrical direction and forming a hot air passage 47 extending from the heating element 3 of the catalyst heater 30 to the ventilation gap 45 via the guide groove 15. There is an effect that it can be used safely and the food and drink container 44 can be kept at an appropriate temperature for a long time.
[0032]
In particular, according to the present invention, although the hot air generated by the oxidative heat generation reaction of the heating element 3 in the catalyst heater 30 is blocked from rising by the bottom of the food and drink container 44, the hot air is provided by providing the guide groove 15 in the support guide plate 2. Is formed in the diametrical direction along the guide groove portion 15 to reach the ventilation gap 45, so that the hot air flow 47a which rises suitably along the ventilation gap 45 can be formed. Therefore, since the hot air can be easily released from the upper opening of the container body 1, the vaporization of the reactant 41 from the cassette container 7 can be promoted, and the catalyst heater 30 is substantially closed inside the container body 1. Nevertheless, it is extremely excellent as it enables the intended effective heating.
