Description

【０００１】
【発明の属する技術分野】
本発明は、細菌培養、細胞培養、及び組織培養などに用いられるシャーレに関する。
【０００２】
【従来の技術】
現在、培養用のシャーレは様々な大きさの径のものが使用されている。一般には、図５に示すように、円形のシャーレ本体１に、円形でシャーレ本体１より大きな径の蓋体２を嵌着する。
【０００３】
特に径の大きいシャーレの場合、その蓋体２は片手では持ちきれず、またその形状が円形のため滑りやすく、シャーレ本体１から蓋体２を持ち上げて、シャーレを開ける際に、蓋体２を持ち損なって落としたり、蓋体２を別の容器や道具にぶつけて破損するという問題がある。
【０００４】
特に、シャーレを細胞培養や組織培養に用いる場合は、クリーンベンチ内で無菌操作を行うため、シャーレ本体１及び蓋体２の保持及び運搬には細心の注意を払うことが必要とされる。
【０００５】
【発明が解決しようとする課題】
本発明は前述の課題を解決すべくなされたものであり、細菌や細胞、組織培養等を無菌的に培養操作する際に、蓋体が、片手で楽に持ちやすく、滑りにくいために、落として破損したりすることのない機能性に優れたシャーレの提供を目的とする。
【０００６】
【課題を解決するための手段】
本発明は、シャーレ本体と該シャーレ本体に嵌着する蓋体とよりなるシャーレにおいて、蓋体の周壁部の外周面に 蓋体の天面部に対して鉛直方向に縦長の突起を複数個設けてなることを特徴とするシャーレを提供する。
【０００７】
【発明の実施の形態】
本発明において、シャーレ本体は底面部と、底面部の外縁部に形成された周壁部とを有している。蓋体は、シャーレ本体に嵌着可能なように、シャーレ本体よりも大径の天面部と、天面部の外縁部に形成された周壁部とを有していて、蓋体の周壁部の外周面に複数個の突起が設けてある。
【０００８】
シャーレ本体及び蓋体の材質としては、ポリスチレンなどの樹脂やガラスなどを用いることができる。
【０００９】
前記突起の高さが１〜２４ｍｍで、幅が２〜２０ｍｍで、長さが３ｍｍ以上であるのが手の指で引っかけやすくて好ましい。
【００１０】
長さは、蓋体の天面部に垂直な方向の高さ以下の長さにすることで、突起のみが蓋体からはみ出して形成されないようにしてある。
【００１１】
突起の高さとは、蓋体の中心から半径方向における、蓋体の周壁部の外周面から突起の頂点までの高さをいう。突起の幅とは、蓋体の周壁部の外周面での、円周方向における突起の端部から端部までの幅をいう。突起の長さとは、蓋体の天面部に垂直な方向の、すなわちシャーレに鉛直方向の、突起の端部から端部までの長さをいう。
【００１２】
突起は、蓋体の周壁部の外周面に等間隔で３個以上設け、隣り合う突起と突起との間隔を蓋体の直径より小さくできるが、前記突起が前記蓋体の周壁部の外周面に等間隔に４個設けてあるのが、持ちやすく、かつ、いくつものシャーレを並べて配置しやすいので好ましい。等間隔に４個設けるとは、前記蓋体の周壁部をほぼ４等分する位置になるようにして設けることをいう。
【００１３】
蓋体の外径がたとえば１２０ｍｍで、その周壁部の外周面に等間隔に４個の突起を設けてある場合、周壁部の外周面からの高さが２５ｍｍ以上である突起になると、隣り合った突起と突起との頂部から頂部までの距離が蓋体の直径より長くなり、蓋体を、手の２本の指で支持して掴みやすくするための突起としては意味をなさず、また、複数個のシャーレを平面状態で並置する際、突起が邪魔になって効率よく置くことができない。
【００１４】
突起の高さがあまり低すぎても指がひっかからないので、突起の高さを１〜２４ｍｍとするのが好ましい。
【００１５】
径の小さいシャーレでは、突起がなくても容易に蓋体は掴めるのであり、蓋体の外径が１２０〜３００ｍｍであるシャーレにおいて突起を設けると、より効果的である。
【００１６】
【実施例】
図１、図４により本発明のシャーレの第１実施例を説明する。シャーレは、ポリスチレン製のシャーレ本体１と、シャーレ本体１に嵌着するポリスチレン製の蓋体２とよりなる。
【００１７】
シャーレ本体１は、直径Ａが１４１ｍｍの底面部４と、底面部４の外縁部に形成された高さＢが２０ｍｍの周壁部５とを有していて、肉厚は１．５ｍｍである。
【００１８】
蓋体２は、シャーレ本体１に嵌着可能なように（詳細には、シャーレ本体１の上部開口を覆って装着すること及び脱着することが可能なように）、シャーレ本体１よりも大径で直径Ｃが１４７ｍｍの天面部１４と、天面部１４の外縁部に形成された高さＤが１２ｍｍの周壁部１５とを有していて、肉厚は１．５ｍｍである。
【００１９】
蓋体２の周壁部１５の外周面に、形状が略円柱状の４個の突起３、３、３、３が設けてある。略円柱状の突起は、高さＨが４ｍｍ、幅Ｗが５ｍｍ、長さＬが１１ｍｍであり、蓋体２の天面部から１ｍｍ低い位置から設けてある。
【００２０】
蓋体２の周壁部１５の外周面に突起３、３、３、３を設けてあるので、手で蓋体２を保持する際は、図４に示すように、その突起３、３に親指と中指をかけて掴み損なうことを防ぎ、シャーレを安全かつ容易に無菌的に操作できる。
【００２１】
図２（ａ）、（ｂ）により本発明のシャーレの第２、３実施例を説明する。図示のように、第２実施例では略三角柱状の突起３、３、３、３が、第３実施例では略直方体状の突起３、３、３、３が、蓋体２の周壁部の外周面に設けてある。寸法などその他の点は第１実施例と同様である。
【００２２】
これらの実施例は、突起３に指をよりひっかかりやすくし、保持性をさらに高めようとした例を示したものであるが、突起３の形状はこれに限定されない。
【００２３】
突起３は、蓋体２の外周壁に等間隔で４個あれば、図３に示すように、複数個のシャーレを平面に効率良く並置でき、なおかつ、手の小さい人にも、突起３、３に指をかけて、シャーレの蓋体が容易に保持できる間隔となる。
【００２４】
【発明の効果】
本発明によるシャーレを用いれば、シャーレの蓋体２を容易にかつ確実に指で掴むことができ、従来の径の大きいシャーレの欠点である、蓋体２を掴み損なって落とし、外来の雑菌が混入したり、培地をこぼすことを避けうるので、本発明は、安全かつ容易な無菌的操作を要求される細胞培養、組織培養等にきわめて有用である。

BACKGROUND OF THE INVENTION
The present invention relates to a petri dish used for bacterial culture, cell culture, tissue culture and the like.
[0002]
[Prior art]
Currently, culture petri dishes with various sizes are used. In general, as shown in FIG. 5, a circular lid body 2 having a diameter larger than that of the petri dish body 1 is fitted to the circular petri dish body 1.
[0003]
In particular, in the case of a petri dish having a large diameter, the lid 2 cannot be held with one hand, and since the shape thereof is circular, the lid 2 is easily slipped. When the petri dish 2 is lifted from the petri dish body 1 and opened, There is a problem that the cover body 2 is dropped due to being held or damaged by hitting the lid 2 against another container or tool.
[0004]
In particular, when the petri dish is used for cell culture or tissue culture, aseptic operation is performed in a clean bench, it is necessary to pay close attention to the holding and transporting of the petri dish body 1 and the lid 2.
[0005]
[Problems to be solved by the invention]
The present invention has been made to solve the above-mentioned problems. When aseptically cultivating bacteria, cells, tissue culture, etc., the lid is easy to hold with one hand and is difficult to slide. The purpose is to provide a petri dish with excellent functionality that is not damaged.
[0006]
[Means for Solving the Problems]
The present invention provides a petri dish comprising a petri dish body and a lid fitted to the petri dish body, wherein a plurality of vertically long protrusions are provided on the outer peripheral surface of the peripheral wall portion of the lid body in a vertical direction with respect to the top surface portion of the lid body The petri dish characterized by becoming is provided.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the petri dish body has a bottom surface portion and a peripheral wall portion formed on the outer edge portion of the bottom surface portion. The lid body has a top surface part having a diameter larger than that of the petri dish body and a peripheral wall part formed on an outer edge part of the top surface part so that the lid body can be fitted, and the outer periphery of the peripheral wall part of the lid body A plurality of protrusions are provided on the surface.
[0008]
As the material for the petri dish body and the lid, a resin such as polystyrene, glass, or the like can be used.
[0009]
It is preferable that the height of the protrusion is 1 to 24 mm, the width is 2 to 20 mm, and the length is 3 mm or more because it is easy to be caught by a finger of a hand.
[0010]
The length is set to a length equal to or less than the height in the direction perpendicular to the top surface portion of the lid so that only the protrusions are not protruded from the lid.
[0011]
The height of the protrusion refers to the height from the outer peripheral surface of the peripheral wall portion of the lid body to the apex of the protrusion in the radial direction from the center of the lid body. The width of the protrusion refers to the width from the end to the end of the protrusion in the circumferential direction on the outer peripheral surface of the peripheral wall portion of the lid. The length of the protrusion refers to the length from the end of the protrusion in the direction perpendicular to the top surface of the lid, that is, in the direction perpendicular to the petri dish.
[0012]
Three or more protrusions are provided at equal intervals on the outer peripheral surface of the peripheral wall portion of the lid, and the interval between the adjacent protrusions and the protrusions can be smaller than the diameter of the lid, but the protrusion is the outer peripheral surface of the peripheral wall portion of the lid body. It is preferable that four are provided at equal intervals because it is easy to hold and it is easy to arrange several petri dishes side by side. The provision of four at equal intervals means that the peripheral wall portion of the lid body is provided so as to be divided into approximately four equal parts.
[0013]
When the outer diameter of the lid is 120 mm, for example, and four protrusions are provided at equal intervals on the outer peripheral surface of the peripheral wall portion, if the height from the outer peripheral surface of the peripheral wall portion is 25 mm or more, it is adjacent The distance from the top of the projection to the top of the projection is longer than the diameter of the lid, and it does not make sense as a projection for supporting the lid with two fingers of the hand for easy grasping, When a plurality of petri dishes are juxtaposed in a flat state, the protrusions become in the way and cannot be placed efficiently.
[0014]
Since the finger does not get caught even if the height of the protrusion is too low, the height of the protrusion is preferably 1 to 24 mm.
[0015]
In a petri dish with a small diameter, the lid can be easily grasped even if there is no projection, and it is more effective to provide a projection in the petri dish whose outer diameter is 120 to 300 mm.
[0016]
【Example】
A first embodiment of the petri dish of the present invention will be described with reference to FIGS. The petri dish is composed of a petri dish body 1 made of polystyrene and a lid 2 made of polystyrene that is fitted to the petri dish body 1.
[0017]
The petri dish body 1 has a bottom surface portion 4 having a diameter A of 141 mm and a peripheral wall portion 5 having a height B of 20 mm formed on an outer edge portion of the bottom surface portion 4 and has a wall thickness of 1.5 mm.
[0018]
The lid body 2 has a larger diameter than the petri dish body 1 so that the lid body 2 can be fitted to the petri dish body 1 (specifically, the lid body 2 can be attached to and detached from the upper opening of the petri dish body 1). The top surface portion 14 having a diameter C of 147 mm and the peripheral wall portion 15 having a height D of 12 mm formed on the outer edge portion of the top surface portion 14 have a wall thickness of 1.5 mm.
[0019]
Four protrusions 3, 3, 3, 3 having a substantially cylindrical shape are provided on the outer peripheral surface of the peripheral wall portion 15 of the lid 2. The substantially cylindrical protrusion has a height H of 4 mm, a width W of 5 mm, and a length L of 11 mm, and is provided from a position 1 mm lower than the top surface portion of the lid 2.
[0020]
Since the protrusions 3, 3, 3, and 3 are provided on the outer peripheral surface of the peripheral wall portion 15 of the lid 2, when the lid 2 is held by hand, as shown in FIG. The middle finger can be prevented from being missed and the petri dish can be safely and easily operated aseptically.
[0021]
Second and third embodiments of the petri dish of the present invention will be described with reference to FIGS. As shown in the drawing, in the second embodiment, the substantially triangular prism-shaped protrusions 3, 3, 3, 3 are in the third embodiment, and in the third embodiment, the substantially rectangular parallelepiped protrusions 3, 3, 3, 3 are formed on the peripheral wall portion of the lid 2. It is provided on the outer peripheral surface. Other points such as dimensions are the same as in the first embodiment.
[0022]
These examples show an example in which a finger is more easily caught on the protrusion 3 to further enhance the retention, but the shape of the protrusion 3 is not limited to this.
[0023]
If there are four projections 3 at equal intervals on the outer peripheral wall of the lid body 2, a plurality of petri dishes can be efficiently juxtaposed on a plane as shown in FIG. A finger is placed on 3 so that the petri dish lid can be easily held.
[0024]
【The invention's effect】
If the petri dish according to the present invention is used, the petri dish lid 2 can be easily and reliably grasped with a finger, and the lid 2, which is a drawback of the petri dish having a large diameter, is missed and dropped. Since contamination and spilling of the medium can be avoided, the present invention is extremely useful for cell culture, tissue culture and the like that require safe and easy aseptic operation.
