【発明の属する技術分野】
本発明は、部材を本体に対して回転可能に取り付けるための簡易軸受及びそれを用いた開閉口付き容器に関するものである。
【０００２】
【従来の技術】
例えば菓子容器では、指先の操作で開閉口を開き、粒状や錠剤型のような内容物を取り出す構造を有するものが見られる。しかし従来は、軸受を本体に設けるとしてもそれ以外に軸と開閉部材の計３部材が必要であった。またあるものは、開閉口を開閉する部材と、この部材を組み付けるための本体部材、それに開閉する部材を本体部材に組み付けた状態に保つ部材の３部材を必要とした。これとともに部品点数を少なくするために、開閉部材の移動量や開閉口の位置などが操作部分の極く近辺に自ずと制限されることになり、面白味の乏しいものにならざるを得ないというのが実情であった。
【０００３】
【発明が解決しようとする課題】
本発明は前記の点に着目してなされたもので、その課題は、最小限度の２部品で構成可能である簡易軸受を提供することである。また本発明の他の課題は、最少限度の部品により、意外性のある動きをするカバー部材によって、開閉が行なわれる開閉口付き容器を提供することである。
【０００４】
【課題を解決するための手段】
前記の課題を解決するため本発明は、本体の外部に設けられ、かつ折り曲げて本体の内側に配置される一対の耳片と、一対の耳片間に部材を回転可能に取り付けるための軸部と、その軸部を軸承するための軸受部とからによって簡易軸受を構成するという手段を講じたものである。
【０００５】
また本発明に係る開閉口付き容器は、本体に内外を通じる開閉口を設け、その本体に、折り曲げて内側に配置される一対の耳片を設け、上記開閉口を開閉するためのカバー部材の一部を一対の耳片間に配置し、カバー部材に軸部を一体成形により設けてそれが嵌まり込む軸受部を耳片に形成するか、或いは、耳片に軸部を一体成形により設けてそれが嵌まり込む軸受部を部材に形成することが望ましい。
【０００６】
【発明の実施の形態】
本発明の簡易軸受は、或る部材を、取り付け対象である本体に、回転可能に取り付けるためのものである。その簡易軸受は、本体の外部に設けられ、かつ折り曲げて本体の内側に配置される一対の耳片を有する。本体の外部にあって、軸受けの一部を構成するときに、本体の内側に配置されるために、一対の耳片は、製造上、本体を射出成形などの手段によって形成するときに、外部に型成形することを可能にする。また構造上は望む位置に耳片を折り曲げることにより、軸承位置を本体内の任意の箇所に設定し得るので、設計上の自由が大きく、開閉口付き容器に意外性のある動きを与えることができる。
【０００７】
一対の耳片間には、部材を回転可能に取り付けるための軸部と、その軸部を軸承するための軸受部とから成る簡易軸受が設けられる。軸部は部材に一体成形して、それが嵌まり込む軸受部を耳片に形成することができる、一方、耳片に軸部を一体成形して、それが嵌まり込む軸受部を部材に設けても良い。耳片の折り曲げ、或いは一体成形というような文言から推測できるように、本発明の簡易軸受はプラスチック材料を射出成形することによって製造する場合に、特に適している。そして、本体と部材の２部品によって、自由度の大きい簡易軸受を得ることができる。
【０００８】
さらに、本発明の簡易軸受を用いて開閉口付き容器を形成することができる。その場合、本体に、本体内外を通じる開閉口を設け、同じく本体の外部に、折り曲げて内側に配置し得る一対の耳片を設ける。耳片を折り曲げたときに設定されることになる軸承位置に近付けるように開閉口の位置を設定することができるので、開閉口の位置などが操作部分の近くに制限されることがない。開閉口を開閉するためのカバー部材（開閉部材）は一部が一対の耳片間に配置されて簡易軸受を構成し、また一部は開閉口を閉じる蓋の役割を果たす。
【０００９】
カバー部材は、指先の操作によって開閉口を一時開き、操作を止めると原位置へ戻る、自動戻り機構を有していて良い。自動戻りのためには弾性力を利用するのが良いが、そのために、カバー部材の一部又は本体の一部に弾性片を一体成形し、弾性力を利用するのは望ましいことである。なおカバー部材の指先操作のために、操作部をカバー部材に設けることができる。
【００１０】
【実施例】
以下図示の実施例により本発明をより詳細に説明する。図１は、本発明に係る簡易軸受を開閉口付き容器に実施した例示であり、１１は下に開いたキャップ状の本体で、容器上部を構成する。１２は開閉口で、本体１１の一側面に開口して内外を通じている。
【００１１】
本体１１の開閉口１２に正対したときに、左右に相当する位置において、本体１１の下端部には一対の耳片１３、１４が薄肉ヒンジ１５、１６を介して折り曲げ可能に、本体１１に一体成形によって設けられている。一対の耳片１３、１４は、薄肉ヒンジ１５、１６を設けている本体１１の位置よりも開閉口１２の方へ寄る向きに傾斜して設けてあり、その先端部に軸受部１７、１８が夫々貫通状に形成されている。従って軸承位置（符号Ａで示す）は、耳片１３、１４の長さと傾斜を変えることで任意に設定することができる（図２）。
【００１２】
カバー部材２１は、開閉口１２を閉じることができる大きさを有しかつまた、本体１１の外周面に適合した曲面から成る形状を有しているカバー部２２を有する。またカバー部２２の付け根の左右に、一対の軸部２３、２４を有しており、これらの軸部２３、２４は、本体内方に折り曲げられた耳片１３、１４の軸受部１７、１８に嵌合し、カバー部材２１を回転可能に支える。カバー部材２１は、カバー部２２の後方に延びた延長片２５を有しており、延長片２５は上部に操作部２６を有していて、先端でカバー部材側のガイド溝１９に係合しつつスライド可能に本体に取り付けられている（図５）。
【００１３】
カバー部材２１のカバー部２２は、図４に示されているように、開閉口１２とは頸部２７で連続している上部開口２８に配置され、頸部２７に支えられるようにして、開閉口１２を開閉するための回転運動をする。上部開口２８を閉じるために、上部カバー部２９がカバー部材２１の付け根側の上面に曲面状に設けられている。
【００１４】
さらに、開閉口１２とは反対側、つまり開閉口１２を前面とすれば後面の方には、薄肉ヒンジ３２を介して弾性片３１が本体に一体成形されている。この弾性片３１は、本体内方へ彎曲させて、先端をカバー部材２１の後部の係合部３３に当てることにより、カバー部材２１を前方へ押圧する。本体下部３４は嵌合部となっており、下部容器３５の上端開口と嵌合して、内部に粒状の菓子などを収める容器を構成する。なお、軸部２３、２４を軸受部１７、１８へ誘導するために、耳片１３、１４は薄肉ヒンジ１５、１６近くに切り欠き部を有しかつそこから軸受部１７、１８へ向けてガイド部１７′、１８′を設けている。
【００１５】
この開閉口付き容器１０は、図５に示すように、カバー部材２１が開閉口内の軸承位置Ａにて本体１１に回転可能に軸支されており、カバー部材２１を回転させることで開閉口１２を閉じ（実線の状態）、また開閉口１２を開くことができる（鎖線の状態）。カバー部材２１は耳片１３、１４で軸承され、操作部２６から適当な距離を置くことができるので、開閉動作や操作方法の自由度が高く、斬新な動きが得られる。
【００１６】
図６、図７は本発明に係る簡易軸受の実施例２を示すもので、自動車玩具本体３６の車輪３７の軸承に適用した例である。前後車輪３７、３７′のために、左右一対の耳片３８、３９、３８′、３９′が設けられており、耳片３８、３９、３８′、３９′は玩具本体の下部に薄肉ヒンジ４５、４６、４５′、４６′を介して設けられ、内方へ折り曲げて配置され、夫々の軸受部４１、４２、４１′、４２′に車輪３７、３７′の軸部４３、４４、４３′、４４′が嵌り込んで軸承されている。よって、極く簡単かつ容易に車輪３７、３７′を装着することができ、その軸承位置も耳片３８…の長さと傾斜等によって設定することができる。
【００１７】
【発明の効果】
本発明は以上の如く構成されかつ作用するものであるから、最少限度の２部品で簡易軸受を構成することができるとともに、それによる軸承位置の設定が容易であるという効果を奏する。また、本発明の簡易軸受により、最少限度の２部品で意外性のあるカバー部材の動きによって開閉される開閉口付き容器を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a simple bearing for rotatably attaching a member to a main body and a container with an opening and closing opening using the same.
[0002]
[Prior art]
For example, some confectionery containers have a structure in which an opening / closing opening is opened by operation of a fingertip to take out contents such as granules or tablets. However, conventionally, even if the bearing is provided on the main body, a total of three members, a shaft and an opening / closing member, are required. Others require three members: a member for opening and closing the opening, a body member for assembling the member, and a member for keeping the member for opening and closing the member in the body member. At the same time, in order to reduce the number of components, the amount of movement of the opening / closing member and the position of the opening / closing port are naturally limited to the very vicinity of the operation part, and it is inevitable that it is not interesting. It was a fact.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and an object thereof is to provide a simple bearing which can be configured with a minimum of two parts. It is another object of the present invention to provide a container with an opening and closing port that can be opened and closed by a cover member that moves unexpectedly with a minimum number of parts.
[0004]
[Means for Solving the Problems]
In order to solve the above-described problem, the present invention provides a pair of ear pieces provided outside a main body and bent and arranged inside the main body, and a shaft part for rotatably mounting a member between the pair of ear pieces. And a bearing portion for bearing the shaft portion.

A part is arranged between a pair of ear pieces, and a shaft part is provided on the cover member by integral molding, and a bearing part to which it is fitted is formed on the ear piece, or a shaft part is provided on the ear piece by integral molding. It is desirable to form a bearing part into which the bearing fits.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
The simple bearing of the present invention is for rotatably attaching a member to a body to be attached. The simple bearing has a pair of lugs provided outside the main body and bent and arranged inside the main body. Since it is located outside the main body and forms a part of the bearing, and is arranged inside the main body, the pair of ear pieces are formed on the outside when the main body is formed by means such as injection molding. It is possible to mold into In addition, by bending the ear piece to the desired position in terms of structure, the bearing position can be set at any point in the main body, so there is great design freedom and it is possible to give unexpected movement to the container with the opening and closing port. it can.
[0007]
A simple bearing including a shaft for rotatably mounting the member and a bearing for bearing the shaft is provided between the pair of ear pieces. The shaft can be integrally formed with the member and the bearing into which it fits can be formed on the lug. On the other hand, the shaft can be integrally formed with the lug and the bearing into which it fits can be formed on the member It may be provided. As can be inferred from terms such as bent earpieces or integral molding, the simple bearing of the present invention is particularly suitable when manufactured by injection molding a plastic material. And a simple bearing with a large degree of freedom can be obtained by the two parts of the main body and the member.
[0008]
Furthermore, a container with an opening and closing port can be formed using the simple bearing of the present invention. In this case, the main body is provided with an opening / closing opening that passes through the inside and outside of the main body, and a pair of ear pieces that can be folded and disposed inside the main body are also provided outside the main body. Since the position of the opening / closing opening can be set so as to approach the bearing position that is set when the ear piece is bent, the position of the opening / closing opening is not limited to the vicinity of the operation portion. A cover member (opening / closing member) for opening / closing the opening / closing part is partially arranged between a pair of ear pieces to constitute a simple bearing, and partly serves as a lid for closing the opening / closing opening.
[0009]
The cover member may have an automatic return mechanism for temporarily opening the opening / closing opening by operation of the fingertip, and returning to the original position when the operation is stopped. It is preferable to use elastic force for automatic return. For this purpose, it is desirable to form an elastic piece integrally with a part of the cover member or a part of the main body and use the elastic force. Note that an operation unit can be provided on the cover member for fingertip operation of the cover member.
