Description

本考案は、紙やプラスチックやセラミックス等からなるコップや茶わん,どんぶり等の容器に係り、特に、高熱の液体の注入時においてその外表面や底表面に結露の生じない非結露容器に関する。   The present invention relates to containers such as cups, tea bowls, and bowls made of paper, plastic, ceramics, and the like, and more particularly, to a non-condensing container that does not cause condensation on the outer surface or bottom surface of a hot liquid when it is injected.

例えば、図4に示すように、温度t1°の氷水や冷水10を紙コップ1bに注入するとこのt1°の温度が紙コップ1b内に伝熱されその外周面や低面を低温にする。外気側の温度t2°がt2>t1の場合、紙コップ1bまわりの温度t2°の外気が冷却され、紙コップ1bの表面や底面に結露が生ずる。一方、逆に高温のコーヒーを紙コップ1b内に注入し外気が低温の場合にも結露が生ずる。 For example, as shown in FIG. 4, when ice water or cold water 10 having a temperature t 1 ° is poured into the paper cup 1b, the temperature at the t 1 ° is transferred into the paper cup 1b to lower the outer peripheral surface or the lower surface. . When the outside air temperature t 2 ° is t 2 > t 1 , the outside air around the paper cup 1b at the temperature t 2 ° is cooled, and condensation occurs on the surface and bottom of the paper cup 1b. On the other hand, dew condensation also occurs when hot coffee is poured into the paper cup 1b and the outside air is cold.

結露が生ずると、紙コップ1bを保持する手の平が濡れ不快感が生ずると共に紙コップ1bをテーブル8上に乗せるとテーブル8上が汚れる不具合が生ずる。また、紙コップ1bの外表面は液体の注入によりすぐ冷たくなり、手の平で保持しずらくなる。このため、従来では、図5に示すように紙コップ1bの外面を断熱部材7で囲み断熱部材7を保持して飲水をする手段が用いられていた。また、テーブル8の表面が濡れないように敷物9やコースタ(図略)等を用いていた。また、容器自体を断熱性のものから形成し、外表面等が低温にならないようにする公知技術があり、例えば、「特許文献1」,「特許文献2」等が挙げられる。
特表2000−516875号(図1) 特開2000−190939号(図1)
When condensation occurs, the palm holding the paper cup 1b gets wet and uncomfortable feelings occur, and when the paper cup 1b is placed on the table 8, the table 8 is soiled. Further, the outer surface of the paper cup 1b is immediately cooled by the liquid injection, and is difficult to hold with the palm. For this reason, conventionally, as shown in FIG. 5, a means for drinking water by surrounding the outer surface of the paper cup 1b with the heat insulating member 7 and holding the heat insulating member 7 has been used. Also, a rug 9 or a coaster (not shown) is used so that the surface of the table 8 does not get wet. Further, there are known techniques for forming the container itself from a heat insulating material so that the outer surface or the like does not become low temperature, such as “Patent Document 1” and “Patent Document 2”.
Special table 2000-516875 (FIG. 1) JP 2000-190939 A (FIG. 1)

特許文献1の特表2000−516875号の「断熱性紙コップ」は内面側がフォーム化されない密度ポリエチレンからなり、この外面をフォーム化された低密度ポリエチレンで囲み全体として断熱性のある紙コップとしたものである。また、「特許文献2」の特開2002−190939号の「発泡ポリプロピレン積層容器」は断熱性のある発泡ポリエチレン層を断熱性のある発泡ポリプロピレン層で囲んだ断熱性のある容器からなる。   Japanese Patent Publication No. 2000-516875 “Heat-insulating paper cup” of Patent Document 1 is made of density polyethylene that is not foamed on the inner surface side, and the outer surface is surrounded by foamed low-density polyethylene to form a heat-insulating paper cup as a whole. Is. “Patented polypropylene laminated container” of Japanese Patent Application Laid-Open No. 2002-190939 of “Patent Document 2” is composed of a heat insulating container in which a heat insulating foamed polyethylene layer is surrounded by a heat insulating foamed polypropylene layer.

図5に示した紙コップ16の場合は、断熱部材7を用いる分だけコスト高となり、断熱部材7が別体の場合は使用の都度断熱部材7を紙コップ1bに嵌め込む必要があり、面倒である。また、図6に示すように敷物9を使用するとその処理が面倒であり、敷物9の廃却が必要となり廃棄物の増大化をまねく。また、「特許文献1」や「特許文献2」の容器は断熱性を有するため結露が生じにくいが、その構造から見てコスト高のものとなる。   In the case of the paper cup 16 shown in FIG. 5, the cost is increased by using the heat insulating member 7, and when the heat insulating member 7 is a separate body, it is necessary to fit the heat insulating member 7 into the paper cup 1b each time it is used. It is. Moreover, when the rug 9 is used as shown in FIG. 6, the process is troublesome, and the rug 9 needs to be discarded, resulting in an increase in waste. In addition, the containers of “Patent Document 1” and “Patent Document 2” have heat insulation properties, so that it is difficult for dew condensation to occur.

本考案は、以上の問題点を解消するもので、比較的低コストで実施でき、外表面や底表面に結露の生じない非結露容器を提供することを目的とする。   An object of the present invention is to solve the above problems, and to provide a non-condensing container that can be implemented at a relatively low cost and does not cause condensation on the outer surface or the bottom surface.

本考案は、以上の目的を達成するために、請求項1の考案は、内部に低熱又は高熱の液体が注入されると共に外面を素手で保持して前記液体を飲み込むために使用される容器であって、該容器は、単一又は複数の素材から形成され、その内部に密閉空隙部を形成することを特徴とする。   In order to achieve the above object, the present invention is a container used for swallowing the liquid while holding the outer surface with bare hands while the liquid of low heat or high heat is injected therein. The container is formed of a single material or a plurality of materials, and has a hermetic void portion formed therein.

4) According to the non-condensing container of claim 4, the non-condensing property can be further improved by making the sealed void portion a dry air layer or a substantially vacuum layer.

以下、本考案の非結露容器の実施の形態を図面を参照して詳述する。本考案の非結露容器としてはコップ,茶わん,どんぶり等のすべての容器が対象であり、その材質も各種のものが含まれ、素材も単一や複数のものが含まれるが、以下の考案では容器としてコップを採用し、その材質としては単一の紙又はプラスチックを用いたものについて説明するが、これに限定するものではない。いずれにしても本考案の非結露容器は内部に密閉空隙部を形成する構造のものを特徴とする。   Hereinafter, an embodiment of the non-condensing container of the present invention will be described in detail with reference to the drawings. Non-condensing containers of the present invention are all containers such as cups, tea bowls, bowls, etc., including various materials, including single or multiple materials. Although a cup is used as a container and a single paper or plastic is used as the material, the present invention is not limited to this. In any case, the non-condensing container of the present invention is characterized by having a structure in which a sealed void is formed inside.

図1,図2は本考案に係るコップ1を示す。コップ1は例えば、プラスチック成形品からなり、内部に密閉空隙部2を形成するものからなる。この密閉空隙部2はコップ1の外面や底面に沿って連続して形成され、コップ1の内面側を外面側とを遮断する構造のものからなる。この密閉空隙部2が完全真空の場合は内面の熱は外面に伝達されないため、低熱の液体を注いでも外面側の温度はほとんど外気温に保持され、結露は生じない。また、この密閉空隙部が乾燥空気や通常の空気層の場合は、内部の熱は外面側に伝達されるが、空気の熱伝導率は訳0.0241w/m・kと極めて低いため断熱効果があり、外面側への熱伝導は極めて少ないものになる。即ち、この密閉空隙層2の形成により、特別の付属物を設けなくても又は特別の材質のものを使用しなくても非結露容器とすることができる。   1 and 2 show a cup 1 according to the present invention. The cup 1 is made of, for example, a plastic molded product, and has a sealed gap portion 2 formed therein. The sealed gap portion 2 is formed continuously along the outer surface and the bottom surface of the cup 1 and has a structure that blocks the inner surface side of the cup 1 from the outer surface side. When the sealed gap 2 is in a complete vacuum, the heat on the inner surface is not transferred to the outer surface, so even when a low-temperature liquid is poured, the temperature on the outer surface side is almost kept at the outside air temperature, and no condensation occurs. In addition, when this sealed void is dry air or a normal air layer, the internal heat is transferred to the outer surface side, but the heat conductivity of the air is as low as 0.0241 w / m · k, so the heat insulating effect. There is very little heat conduction to the outer surface side. That is, the formation of the sealed void layer 2 makes it possible to form a non-condensing container without providing any special accessories or using a special material.

この密閉空隙層2をどのような容積にすればよいかは、コップ1の材質や使用される液体の温度や使用される外気の温度等により変るため、これ等の各条件を考慮し、理論的又は実験的に決めることが望ましい。なお、この密閉空隙部2を材質が紙のものについて形成するには特別の製造方法や必要があり、また、プラスチックの場合は成形型等が必要になるが、公知技術を適用することにより、十分に可能である。   The volume of the sealed void layer 2 that can be used varies depending on the material of the cup 1, the temperature of the liquid used, the temperature of the outside air used, and the like. It is desirable to determine automatically or experimentally. In addition, a special manufacturing method or a necessity is required to form the sealed gap portion 2 with a paper material, and in the case of plastic, a molding die or the like is required, but by applying a known technique, It is possible enough.

図3(a),(b)はコップ1を紙コップとした場合の本考案に係る非結露容器を製作する簡便の製作方法の一例を示すものである。この紙コップ1aは、既存の第1の紙コップ3とこれよりやや小型の既存の第2の紙コップ4を用い、これを図3(a)のように重合し、その中間に支持台5や支持リング6を介存させる。この支持台5や支持リング6の寸法を適宜決めることにより、図3(b)に示すように第1の紙コップ3と第2の紙コップ4との間に密閉空隙部2aを形成することができる。なお、支持リング6を第1の紙コップ3や第2の紙コップ4側とに固着することが必要となるが、この固着は容易に可能である。また、支持台5や支持リング6は耐熱性の材料のものを用いることは勿論である。   3 (a) and 3 (b) show an example of a simple manufacturing method for manufacturing a non-condensing container according to the present invention when the cup 1 is a paper cup. This paper cup 1a uses an existing first paper cup 3 and an existing second paper cup 4 that is slightly smaller than this, and superimposes them as shown in FIG. And support ring 6 are interposed. By appropriately determining the dimensions of the support base 5 and the support ring 6, a sealed gap 2 a is formed between the first paper cup 3 and the second paper cup 4 as shown in FIG. Can do. Although it is necessary to fix the support ring 6 to the first paper cup 3 or the second paper cup 4 side, this fixing is easily possible. Of course, the support 5 and the support ring 6 are made of heat-resistant materials.

本考案の非結露容器は紙コップやプラスチックのコップに限定されず、低熱又は高熱の液体の注入の必要性のあるすべての容器に適用される。特に、一般に冷水や氷水が注入されるコップに対しては適用性が高い。また、この製造方法もプラスチック成型等を用いることにより多量生産ができる。   The non-condensing container of the present invention is not limited to paper cups or plastic cups, but is applicable to all containers that require injection of low or high heat liquid. In particular, the applicability is high for cups into which cold water or ice water is generally poured. In addition, this manufacturing method can be mass-produced by using plastic molding or the like.
