本考案はシヤーレ蓋、更に詳細には細菌の培養
試験等種々の試験に用いられるシヤーレの蓋に関
する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shear dish lid, and more particularly to a shear dish lid used for various tests such as bacterial culture tests.
従来、シヤーレ蓋の天壁は単なる透明平板体に
よつて構成せられていたに過ぎなかつた。
Hitherto, the top wall of a tray lid has been simply constructed of a transparent flat plate.
そのため、細菌の培養試験等に於けるコロニー
の観察の如く、微小物をシヤーレ蓋の外部より観
察せんとするときには、甚だ困難な結果を招いて
いたのが実状であつた。
Therefore, when attempting to observe microscopic objects from outside the jar lid, such as when observing colonies in bacterial culture tests, the actual situation was extremely difficult.
そこで、本考案者は斯かる従来の欠点を解消す
べく鋭意検討を重ねた結果、微小物の観察に好適
な本考案シヤーレ蓋を案出したものである。 Therefore, the inventor of the present invention has made extensive studies to eliminate such drawbacks of the conventional technology, and has devised the present invention's shear dish lid, which is suitable for observing minute objects.
すなわち、本考案は蓋体天壁の中央部より周端
寄り部に下面のみ膨出した平凸レンズ部を形成せ
しめたことを特徴とするシヤーレ蓋である。
That is, the present invention is a shear dish lid characterized in that a plano-convex lens portion is formed with only the lower surface bulging from the center portion of the top wall of the lid body toward the peripheral end.
以下本考案を一実施例を示す図面と共に更に説
明する。
The present invention will be further explained below with reference to drawings showing one embodiment.
１は蓋体で天壁１１の一部に凸レンズ部２が適
宜数形設せられているものである。蓋体１の材質
としては従来シヤーレ蓋と同様透明ガラス、合成
樹脂等が好ましく、また形態としては容器体３へ
の被冠保持に有利な周壁１２を有するものが望ま
しい。 Reference numeral 1 denotes a lid body on which a suitable number of convex lens parts 2 are provided on a part of the ceiling wall 11. The material of the lid 1 is preferably transparent glass, synthetic resin, etc., as in the case of conventional shear dish lids, and the shape is preferably one having a peripheral wall 12 which is advantageous for retaining the cap on the container body 3.
凸レンズ部２は、適宜蓋体１を回転せしめるこ
とにより、１個のレンズ部でも相当部分の拡大観
察が可能となる如く、天壁１１の中央部ではなく
周端寄り部、すなわち半径線上に形成せられる。 The convex lens part 2 is formed not in the center of the ceiling wall 11 but near the peripheral end, that is, on the radial line, so that by appropriately rotating the lid body 1, a considerable portion can be observed under magnification even with one lens part. be given
また、該凸レンズ部２は、シヤーレの積み重ね
又は輸送時等に接触によるキズ等損傷の発生を防
止するため、天壁１１の下面にのみ膨出し、上面
は平面をなす平凸レンズとする。 In addition, the convex lens portion 2 is a plano-convex lens that bulges only on the lower surface of the top wall 11 and has a flat upper surface in order to prevent damage such as scratches due to contact during stacking or transportation of shears.
尚、凸レンズ部２の具体的形状は円形、方形状
等の如何を問わず、またその大きさも蓋体１の大
きさに対応して適宜選定されるが、通常蓋体１の
直径の15〜35％程度の径寸法ｌとするのが良い結
果を与える。 The specific shape of the convex lens portion 2 may be circular, rectangular, etc., and its size may be appropriately selected depending on the size of the lid 1, but it is usually 15 to 15 times the diameter of the lid 1. Good results are obtained by setting the diameter l to about 35%.
斯かる凸レンズ部２の具体的形成法もその如何
を問わないが、例えば型成型による蓋体との一体
成型が好適である。 Although the specific method of forming the convex lens portion 2 is not limited, it is preferable to form the convex lens portion 2 integrally with the lid body by molding, for example.
以上の如く本考案は構成せられるので、当該凸
レンズ部を通して観察すれば、微小物も拡大換算
される。
Since the present invention is configured as described above, even minute objects can be magnified when observed through the convex lens section.
従つて、本考案シヤーレ蓋を用いれば、細菌の
培養試験等、微小物の観察を伴う各種試験を極め
て容易かつ有利に行うことができる。
Therefore, by using the shear dish lid of the present invention, various tests involving observation of microscopic objects, such as bacterial culture tests, can be carried out extremely easily and advantageously.
特に本考案シヤーレ蓋は、天壁１１の中央部よ
り周端寄り部の半径線上に凸レンズ部２が形成せ
られているため、適宜蓋体１を回転せしめること
により、ほぼ全域を明瞭な拡大状態にて観察する
ことができる。 In particular, in the present invention, the present invention has a convex lens portion 2 formed on the radius line from the center to the peripheral edge of the top wall 11, so by appropriately rotating the lid 1, almost the entire area can be clearly enlarged. It can be observed at.
また、本考案に於ける凸レンズ部２は、シヤー
レの積み重ねや輸送時に於けるレンズ部の損傷を
防止することができる。 Further, the convex lens portion 2 of the present invention can prevent damage to the lens portion during stacking and transportation of shears.
図面は本考案の実施例を示すもので、第１図は
その平面図、第２図は要部断面正面説明図であ
る。
The drawings show an embodiment of the present invention, and FIG. 1 is a plan view thereof, and FIG. 2 is a front explanatory cross-sectional view of the main part.
