Description

この発明は、つけ麺などに使用される保温用食器に関するものである。   The present invention relates to a warming tableware used for tsukemen and the like.

飲食店では、調理した中華ラーメンやうどんを食器(丼、鉢)に入れた状態でお客に出してしばらくすると、麺自体はもちろんつゆ又はスープ自体が冷めてしまい、本来の味を保つことができず、幾つかの工夫がされている。
例えば熱せられて石の器に茹でたラーメンや、高熱のスープを入れて、保温効果を長時間維持する方法(特開2006−230378号公報)、つけ麺にあってはつゆ又はスープを入れた食器内に熱した自然石を入れて、つゆ又はスープの保温維持を図るなどの工夫がされている。
特開2006−230378号公報
In a restaurant, after cooking Chinese ramen and udon in tableware (bowl, bowl) and serving them for a while, the noodles and soup itself will cool down and the original taste can be maintained. There are some ideas.
For example, a method of maintaining a heat-retaining effect for a long time by putting boiled ramen or high-heated soup in a stone bowl (Japanese Patent Laid-Open No. 2006-230378), tableware with soup or soup for tsukemen It has been devised to put hot natural stones inside to keep the soup or soup warm.
JP 2006-230378 A

熱せられた石の器を使用する方法は、食事前または直後に客が石の器に触れて火傷をするおそれがあることはもちろんであるが、加熱の対象となる石の器は比較的大きくて重量があるために加熱処理が面倒である。
また自然石を使用する方法は、自然石の加熱処理がし易いものの、対象となる自然石は特定の種類のものに限定され、お客が食事の最後に残りのつゆ又はスープを飲む際に、自然石が食器内で安定しないから飲みにくい。この課題を解決するために、自然石を板状に加工することが考えられるが、加工に手間と費用がかかる課題が新たに生じる。
この発明の目的は、扱いが簡易であって、安価な保温用食器を提供することにある。
The method of using a heated stone vessel is not to mention that there is a risk that the customer may touch the stone vessel immediately before or immediately after eating, but the stone vessel to be heated is relatively large. The heat treatment is troublesome because of its weight.
In addition, natural stones are easy to heat, but the target natural stones are limited to certain types.When customers drink the remaining soup or soup at the end of their meal, It is difficult to drink because natural stone is not stable in the tableware. In order to solve this problem, it is conceivable to process natural stone into a plate shape, but a new problem arises that requires labor and cost for processing.
An object of the present invention is to provide an inexpensive warm tableware that is easy to handle.

This is because the space and the gap are continuous .

この発明によれば、保温板はセラミックス製でかつ板状のものであるから、扱いが簡易であり、量産化が可能であるので、安価な保温用食器を提供することができる。   According to this invention, since the heat insulating plate is made of ceramics and is plate-shaped, it is easy to handle and can be mass-produced, so that it is possible to provide an inexpensive tableware for heat insulating.

この発明に係る保温用食器について図1〜図4を参照して説明する。
図1及び図2に示す保温用食器1は、食器本体2とこの食器本体に出し入れ自在であるセラミックス製の保温板3とを備えている。
The tableware for heat insulation which concerns on this invention is demonstrated with reference to FIGS.
The tableware 1 for heat insulation shown in FIG.1 and FIG.2 is provided with the tableware main body 2 and the heat insulating board 3 made from ceramics which can be taken in and out of this tableware main body.

食器本体2は陶磁器からなり、図1〜図3に示すように、上端開口の有底の容器であって、図1に示す例では丼状(鉢状、碗状)に形成されている。食器本体2は内底部に収納凹部2aを形成してある。収納凹部2aの内部形状は平面円形状に形成されている。収納凹部2aの内周壁2a1は、収納凹部2aの外方に向けて上り勾配の傾斜面となっている。   As shown in FIGS. 1 to 3, the tableware main body 2 is a bottomed container having an upper end opening, and in the example shown in FIG. 1, it is formed in a bowl shape (bowl shape, bowl shape). The tableware main body 2 has a storage recess 2a formed in the inner bottom. The internal shape of the storage recess 2a is formed in a planar circular shape. The inner peripheral wall 2a1 of the storage recess 2a is an inclined surface having an upward slope toward the outside of the storage recess 2a.

セラミックス製の保温板3は食器本体2の収納凹部2a内に離脱可能に収納されている。保温板3は、収納凹部2aの内部形状に対応し、図2及び図4に示す例では、円板状に形成されている。保温板3の外周面3aは、外方に向けて上り勾配の傾斜面となっている。
保温板3は、図1に示すように収納凹部2a内に収納されている状態では、外周面3aと収納凹部2aの内周壁2a1との間に隙間4が開けられている。保温板3の上面は、食器本体2の内周段部2bと同一平面を形成している。
The ceramic heat insulating plate 3 is detachably stored in the storage recess 2 a of the tableware body 2. The heat insulating plate 3 corresponds to the internal shape of the housing recess 2a, and is formed in a disk shape in the example shown in FIGS. The outer peripheral surface 3a of the heat insulating plate 3 is an inclined surface having an upward slope toward the outside.
In the state in which the heat insulating plate 3 is housed in the housing recess 2a as shown in FIG. 1, a gap 4 is opened between the outer peripheral surface 3a and the inner peripheral wall 2a1 of the housing recess 2a. The upper surface of the heat insulating plate 3 forms the same plane as the inner peripheral step 2 b of the tableware body 2.

次に、保温用食器の使用方法について説明する。
食器本体2内に熱した飲食用液体5を入れてから、加熱手段によって加熱した保温板3をこの食器本体内に落とし込み、その後、図1に示すように保温板を収納凹部2a内に収納する。すると、保温板3から放出される熱は保温板上方の飲食用液体5に伝えられ、外気に接している飲食用液体は、時間の経過と共に次第に冷めていくが、保温板の放熱効果によって温度低下が抑制され、保温される。保温板3はセラミックス製であるから、比熱が高く冷めにくく、しかも食器本体2の内底部に位置して外気に接していないので、その放熱によって飲食用液体の保温効果を長く維持することができる。食器本体2自体が陶磁器製であるので、保温性が良く、飲食用液体の保温維持に寄与し、また熱伝導率が低い性質を有することから、飲食用液体5がかなり熱くても食器本体表面は熱くなりにくく、したがって食器本体を持つことができる。
加熱された保温板3から遠赤外線が発生し、飲食用液体5の味の向上を期待することができる。
具体的な使用例として、食器本体2をつけ麺容器、飲食用液体5をつけ汁として用いる場合には、つけ麺容器内に熱したつけ汁を入れてから、コンロ上で加熱した保温板3をこのつけ麺容器内に落とし込み、保温板を収納凹部2a内に収納すると、保温板からの熱はつけ汁に伝えられる。この場合、お客は冷えた麺類をつけ麺容器内のつけ汁に浸して食するが、繰り返す浸し行為によってつけ汁が徐々に冷めていくが、保温板の放熱効果によって保温されるので、冷めて行くスピードが遅くなり、食事を終えるまで保温されたつけ汁を利用することができる。
Next, the usage method of the tableware for heat insulation is demonstrated.
After putting the heated eating and drinking liquid 5 in the tableware body 2, the heat insulating plate 3 heated by the heating means is dropped into the tableware main body, and then the heat insulating plate is stored in the storage recess 2a as shown in FIG. . Then, the heat released from the heat insulating plate 3 is transmitted to the food / beverage liquid 5 above the heat insulating plate, and the food / beverage liquid in contact with the outside air gradually cools with the passage of time. The decrease is suppressed and heat is maintained. Since the heat insulating plate 3 is made of ceramics, it has a high specific heat and is difficult to cool, and since it is located on the inner bottom of the tableware body 2 and is not in contact with the outside air, the heat retention effect of the liquid for eating and drinking can be maintained for a long time by its heat dissipation. . Since the tableware body 2 itself is made of porcelain, it has good heat retention, contributes to maintaining the temperature of the liquid for eating and drinking, and has a low thermal conductivity. Is less likely to get hot and therefore can have a tableware body.
Far-infrared rays are generated from the heated heat insulating plate 3, and an improvement in the taste of the liquid 5 for eating and drinking can be expected.
As a specific example of use, when using the tableware body 2 as a noodle container and the eating and drinking liquid 5 as a soup, put the heated soup into the tsukemen container and then heat the heat retaining plate 3 heated on the stove. When dropped into the tsukemen container and the heat insulating plate is stored in the storage recess 2a, the heat from the heat insulating plate is transferred to the soup. In this case, customers eat cold noodles soaked in soup stock in a noodle container, but the soup gradually cools by repeated soaking, but it is kept warm by the heat dissipation effect of the heat insulating plate, so it cools You can use hot soup that is kept warm until you finish the meal.

この発明に係る保温用食器の他の実施の形態について図5〜図7を参照して説明する。
図5及び図6に示す保温用食器11は、図1及び図2に示す保温用食器1と実質的に同一であるが、相違点はセラミックス製の保温板13が溝13bを有するが、保温板3にはこのような溝を設けていないことである。
以下、保温用食器11における特徴のみを説明し、その他の構成について保温用食器1と共通する構成に関しては必要に応じて説明する。そして保温用食器11を説明するために用いる符号に関しても、共通する構成については保温用食器1の説明に用いた符号をそのまま使用している。
Another embodiment of the warming tableware according to the present invention will be described with reference to FIGS.
The warming tableware 11 shown in FIGS. 5 and 6 is substantially the same as the warming tableware 1 shown in FIGS. 1 and 2, except that the ceramic warming plate 13 has a groove 13 b. The plate 3 is not provided with such a groove.
Hereinafter, only the features of the warming tableware 11 will be described, and other configurations will be described as necessary with respect to the configuration common to the warming tableware 1. And also about the code | symbol used in order to demonstrate the tableware 11 for heat retention, the code | symbol used for description of the tableware 1 for heat retention is used as it is about the common structure.

保温用食器11の保温板13は裏面に単一又は複数の溝13bを横断状態に設けてある。図6に示す例では、3本の溝13bは図上下方向に等間隔を置いて形成されている。各溝13bは、図5に示すように、保温板13の一側(図左側)の外周面13aから他側の外周面に達している。このため、保温板13の外周の隙間4と各溝13bとは連なっている。   The heat insulating plate 13 of the heat insulating tableware 11 is provided with a single or a plurality of grooves 13b in the transverse state on the back surface. In the example shown in FIG. 6, the three grooves 13b are formed at equal intervals in the vertical direction of the figure. As shown in FIG. 5, each groove 13 b reaches from the outer peripheral surface 13 a on one side (left side in the drawing) of the heat insulating plate 13 to the outer peripheral surface on the other side. For this reason, the clearance gap 4 and the grooves 13b on the outer periphery of the heat insulating plate 13 are continuous.

保温用食器11において、保温板13は溝13bを横断的にかつ隙間4と連なるように設けているので、次のような効果を期待することができる。
保温板13の裏面の表面積が拡大されるから、放熱面が広がることによって飲食用液体5に対する保温効果が増すことである。
保温板13の裏面側の溝13bを通じて温められた飲食用液体5の熱が上昇され、食器本体2の上側の冷えつつある飲食用液体の熱は降下されることから、飲食用液体の熱が保温板の周りを対流するようになり、保温効果維持に寄与することである。
使用後に、食器本体2から保温板13を取り出す際、保温板の裏面が収納凹部2aの内底面に密着しにくく、保温板を取り出しやすいことである。
In the warming tableware 11, since the warming plate 13 is provided so as to cross the groove 13b and to be continuous with the gap 4, the following effects can be expected.
Since the surface area of the back surface of the heat retaining plate 13 is enlarged, the heat retaining effect for the liquid 5 for eating and drinking is increased by spreading the heat radiating surface.
Since the heat of the eating and drinking liquid 5 heated through the groove 13b on the back surface side of the heat retaining plate 13 is raised and the heat of the cooling eating and drinking liquid on the upper side of the tableware body 2 is lowered, the heat of the eating and drinking liquid is reduced. The convection around the heat insulation plate will contribute to the maintenance of the heat insulation effect.
When the heat insulating plate 13 is taken out from the tableware body 2 after use, the rear surface of the heat insulating plate is difficult to adhere to the inner bottom surface of the storage recess 2a, and the heat insulating plate can be easily taken out.

この発明に係る保温用食器のさらに他の実施の形態について図8及び図9を参照して説明する。
図8及び図9に示す保温用食器21は、図1及び図2に示す保温用食器1と実質的に同一であるが、相違点は収納凹部2aの内周壁に突起状の保持台2cを設け、セラミックス製の保温板23の厚みを薄形していることである。
以下、保温用食器21における特徴のみを説明し、その他の構成について保温用食器1との共通する構成に関しては必要に応じて説明する。そして保温用食器21を説明するために用いる符号に関しても、保温用食器1と共通する構成については保温用食器1の説明に用いた符号をそのまま使用している。
Still another embodiment of the warming tableware according to the present invention will be described with reference to FIGS.
The warming tableware 21 shown in FIGS. 8 and 9 is substantially the same as the warming tableware 1 shown in FIGS. 1 and 2, except that a projecting holding table 2 c is provided on the inner peripheral wall of the storage recess 2 a. The thickness of the ceramic heat insulating plate 23 is reduced.
Hereinafter, only the features of the warming tableware 21 will be described, and other configurations will be described as necessary with respect to the configuration common to the warming tableware 1. In addition, regarding the reference numerals used to describe the warming tableware 21, the reference numerals used in the description of the warming tableware 1 are used as they are for the configuration common to the warming tableware 1.

突起状の保持台2cは正面L形に形成され、食器本体2の収納凹部2aの内周壁の複数個所(図8では三個所)に間隔を置いて設けられ、収納凹部の内底面まで伸びている。保温板23は、裏面側を保持台2c上に載せられた状態で位置保持されると共に、収納凹部2a内に収納されている。保温板23は、収納凹部2a内に収納されている状態で、裏面と収納凹部の内底面との間に所定の空間24が開けられている。空間24の外周側は隙間4に連なっている。このため、空間24と隙間4とは、保温板23上方に至る通路を形成している。23aは保温板23の外周面である。
保温用食器21は、上記構成であるから、保温板23の裏面側の空間24及びこの空間に連なる隙間4を通じて温められた飲食用液体の熱が保温板23の周りを対流するようになり、保温効果の持続性が確保される。
The protrusion-like holding base 2c is formed in a front L shape, and is provided at a plurality of locations (three locations in FIG. 8) on the inner peripheral wall of the storage recess 2a of the tableware body 2 and extends to the inner bottom surface of the storage recess. Yes. The heat insulating plate 23 is held in a state where the back surface is placed on the holding table 2c, and is stored in the storage recess 2a. In the state where the heat insulating plate 23 is stored in the storage recess 2a, a predetermined space 24 is opened between the back surface and the inner bottom surface of the storage recess. The outer peripheral side of the space 24 continues to the gap 4. For this reason, the space 24 and the gap 4 form a passage that extends above the heat insulating plate 23. Reference numeral 23 a denotes an outer peripheral surface of the heat insulating plate 23.
Since the tableware 21 for heat insulation is the said structure, the heat | fever of the liquid for eating and drinking heated through the space 24 on the back surface side of the heat insulation board 23 and the clearance gap 4 connected to this space comes to convect around the heat insulation board 23, Sustainability of heat insulation effect is ensured.

食器本体2の材質は陶器、磁気の双方を含むものである。食器本体2の収納凹部2aの内部形状及び保温板3,13,23の平面形状は多角形であっても良いが、内部及び平面のそれぞれの形状が円形であることによって、食器本体2内に保温板を入れる方向が制限されることはなく、どの方向から入れても保温板を円滑に収納凹部内に納めることができる。
保温用食器11の保温板13に設ける溝13bは裏面のみに限定されず、上面に設けても良い。
保温用食器1,11,21は、麺類用、スープ用、つゆ用など食器本体内に入れる飲食用内容物を保温することを目的とするものに広く利用することができる。
The material of the tableware body 2 includes both pottery and magnetism. Although the polygonal shape may be sufficient as the internal shape of the storage recessed part 2a of the tableware main body 2, and the heat insulating board 3,13,23, since each shape of an inside and a plane is circular, in the tableware main body 2 The direction in which the heat insulating plate is inserted is not limited, and the heat insulating plate can be smoothly accommodated in the storage recess regardless of the direction.
