In addition, the sealing material 5 may be applied only to a part of the upper end of the side wall 3, for example. Further, the sealing material 5 may be applied to the outer edge of the water tank lid 4 and adhered to the water tank lid 4 while not being adhered to the side wall 3 .

図１～図４に示すように、水槽用蓋４は、開閉可能な第１板４１と、第１板４１の開閉を支持する第２板４２と、第１板４１と第２板４２とを回動可能に連結するヒンジ部４３と、を備える。これにより、水槽用蓋４を取り外すことなく、第１板４１を開くことによって水槽１内の観賞魚や小動物などに餌を与えることができる。なお、水槽用蓋４は、例えば、第２板４２が開閉可能であってもよい。 As shown in FIGS. 1 to 4, the water tank lid 4 includes a first plate 41 that can be opened and closed, a second plate 42 that supports the opening and closing of the first plate 41, and the first plate 41 and the second plate 42. and a hinge portion 43 that rotatably connects the . Thus, by opening the first plate 41 without removing the aquarium cover 4, ornamental fish and small animals in the aquarium 1 can be fed. Note that the water tank lid 4 may be such that the second plate 42 can be opened and closed, for example.

第１板４１及び第２板４２は、それぞれの上面４１ａ，４２ａが実質的に面一となるようにヒンジ部４３に連結されている。実質的に面一とは、二つの面が完全に平坦な場合だけでなく、１ｍｍ以上の段差（凹凸）がない実質的に平坦な場合も含む。第１板４１及び第２板４２の厚みは、特に限定されないが、同じである。第１板４１及び第２板の材質は、同じであってもよく、異なっていてもよい。 The first plate 41 and the second plate 42 are connected to the hinge portion 43 so that the respective upper surfaces 41a and 42a are substantially flush with each other. "Substantially flush" includes not only the case where the two surfaces are completely flat, but also the case where the two surfaces are substantially flat without a step (unevenness) of 1 mm or more. Although the thicknesses of the first plate 41 and the second plate 42 are not particularly limited, they are the same. The materials of the first plate 41 and the second plate may be the same or different.

本実施形態において、第１板４１は、特に限定されないが、三角形状に形成されている。水槽用蓋４の外周面を構成する第１板４１の側面４１ｂは、特に限定されないが、側壁３よりも水槽１の外側に若干（例えば、２ｍｍ）飛び出している。これにより、第１板４１に指が引っ掛かりやすくなり、第１板４１の開閉が容易となる。なお、例えば、第１板４１は、長方形状に形成されていてもよく、第１板４１の側面４１ｂは、側壁３と実質的に面一であってもよい。 In this embodiment, the first plate 41 is formed in a triangular shape, although not particularly limited. A side surface 41 b of the first plate 41 that constitutes the outer peripheral surface of the water tank lid 4 protrudes slightly (for example, 2 mm) to the outside of the water tank 1 than the side wall 3 , although this is not particularly limited. As a result, fingers can easily be caught on the first plate 41, and opening and closing of the first plate 41 is facilitated. In addition, for example, the first plate 41 may be formed in a rectangular shape, and the side surface 41 b of the first plate 41 may be substantially flush with the side wall 3 .

第１板４１は、第１板４１の開閉時に第２板４２が側壁３からずれることを抑える観点から、第２板４２よりも小さいことが好ましい。 The first plate 41 is preferably smaller than the second plate 42 from the viewpoint of preventing the second plate 42 from slipping from the side wall 3 when the first plate 41 is opened and closed.

本実施形態において、第２板４２は、特に限定されないが、長方形の一隅が切り欠かれた形状に形成されている。水槽用蓋４の外周面を構成する第２板４２の側面４２ｂは、特に限定されないが、側壁３よりも水槽１の外側に若干（例えば、２ｍｍ）飛び出している。これにより、第２板４２に指が引っ掛かりやすくなり、水槽用蓋４の取り外しが容易となる。なお、例えば、第２板４２は、長方形状に形成されていてもよく、第２板４２の側面４２ｂは、側壁３と実質的に面一であってもよい。 In the present embodiment, the second plate 42 is formed in a rectangular shape with one corner notched, although this is not a particular limitation. A side surface 42b of the second plate 42 that constitutes the outer peripheral surface of the water tank lid 4 protrudes slightly (for example, 2 mm) to the outside of the water tank 1 than the side wall 3, although not particularly limited. As a result, fingers can easily be caught on the second plate 42, and the water tank lid 4 can be easily removed. In addition, for example, the second plate 42 may be formed in a rectangular shape, and the side surface 42 b of the second plate 42 may be substantially flush with the side wall 3 .

ヒンジ部４３は、弾性材で形成され、第１板４１及び第２板４２のそれぞれの対向する側面（対向面ともいう）４１ｄ，４２ｄを連結している。斯かる構成によれば、第１板４１を上面４１ａ側及び下面４１ｃ側のどちらにも回動させることができる。これにより、例えば、水槽用蓋４を裏表反対に側壁３に載置した場合でも、第１板４１の開閉が可能である。 The hinge portion 43 is made of an elastic material, and connects opposing side surfaces (also referred to as opposing surfaces) 41d and 42d of the first plate 41 and the second plate 42, respectively. According to such a configuration, the first plate 41 can be rotated to either the upper surface 41a side or the lower surface 41c side. As a result, for example, the first plate 41 can be opened and closed even when the water tank lid 4 is placed on the side wall 3 upside down.

弾性材としては、シリコン系シーリング材、変性シリコン系シーリング材、ポリウレタン系シーリング材、ポリサルファイド系シーリング材などが挙げられる。ヒンジ部４３（弾性材）は、水槽用蓋４の見栄えをよくする観点から、第１板４１や第２板４２と同じ色であることが好ましい。 Examples of elastic materials include silicon-based sealants, modified silicon-based sealants, polyurethane-based sealants, polysulfide-based sealants, and the like. The hinge portion 43 (elastic material) preferably has the same color as the first plate 41 and the second plate 42 from the viewpoint of improving the appearance of the water tank lid 4 .

ヒンジ部４３の上面４３ａは、第１板４１及び第２板４２のそれぞれの上面４１ａ，４２ａと実質的に面一又はより凹んでいる。本実施形態において、ヒンジ部４３は、特に限定されないが、第１板４１及び第２板４２のそれぞれの上面４１ａ，４２ａより凹んだ凹み４３１を備える。 The upper surface 43a of the hinge portion 43 is substantially flush with or recessed from the upper surfaces 41a and 42a of the first plate 41 and the second plate 42, respectively. In this embodiment, the hinge portion 43 is provided with a recess 431 that is recessed from the upper surfaces 41a and 42a of the first plate 41 and the second plate 42, although this is not a particular limitation.

凹み４３１は、特に限定されないが、ヒンジ部４３の上部に配置され、ヒンジ部４３の長手方向に連続して延びている。なお、凹み４３１は、例えば、ヒンジ部４３の下部に配置されていてもよく、ヒンジ部４３の長手方向に不連続に複数配置されていてもよい。 The recess 431 is not particularly limited, but is arranged above the hinge portion 43 and extends continuously in the longitudinal direction of the hinge portion 43 . For example, the recesses 431 may be arranged below the hinge portion 43 , or may be arranged discontinuously in the longitudinal direction of the hinge portion 43 .

本実施形態において、凹み４３１は、湾曲状に形成されているが、これに限られない。例えば、凹み４３１は、Ｖ字状に形成されていてもよい。凹み４３１の両端は、特に限定されないが、第１板４１及び第２板４２のそれぞれの上面４１ａ，４２ａと同じ高さである。凹み４３１の深さＨ１は、ヒンジ部４３の厚みＴ１の３０～９０％であることが好ましい。 Although the recess 431 is formed in a curved shape in this embodiment, it is not limited thereto. For example, the recess 431 may be V-shaped. Both ends of the recess 431 are at the same height as the upper surfaces 41a and 42a of the first plate 41 and the second plate 42, respectively, although not particularly limited. The depth H1 of the recess 431 is preferably 30 to 90% of the thickness T1 of the hinge portion 43.

ヒンジ部４３の下面４３ｃは、特に限定されないが、第１板４１及び第２板４２のそれぞれの下面４１ｃ，４２ｃと実質的に面一である。なお、ヒンジ部４３の下部は、例えば、第１板４１及び第２板４２のそれぞれの下面４１ｃ，４２ｃより下側に隆起し、第１板４１及び第２板４２のそれぞれの下面４１ｃ，４２ｃと連結されている、という構成であってもよい。 The lower surface 43c of the hinge portion 43 is substantially flush with the lower surfaces 41c and 42c of the first plate 41 and the second plate 42, although not particularly limited. In addition, the lower portion of the hinge portion 43 protrudes downward from the respective lower surfaces 41c, 42c of the first plate 41 and the second plate 42, for example, and the lower surfaces 41c, 42c of the first plate 41 and the second plate 42, respectively. It may be a configuration that is connected to.

ヒンジ部４３の幅Ｗ１は、第１板４１の回動（開閉）を良好にする観点から、ヒンジ部４３の厚みＴ１よりも大きいことが好ましい。ヒンジ部４３は、第１板４１と第２板４２との間を埋めるように連続して延びているが、これに限られない。例えば、ヒンジ部４３は、第１板４１と第２板４２との間に不連続に複数配置されていてもよい。 The width W1 of the hinge portion 43 is preferably larger than the thickness T1 of the hinge portion 43 from the viewpoint of improving the rotation (opening and closing) of the first plate 41 . The hinge portion 43 continuously extends to fill the space between the first plate 41 and the second plate 42, but is not limited to this. For example, a plurality of hinge portions 43 may be arranged discontinuously between the first plate 41 and the second plate 42 .

次に水槽用蓋４の製造方法の一例を説明する。 Next, an example of a method for manufacturing the water tank lid 4 will be described.

まずは、一枚の板を用意し、ヒンジ部４３を設ける部分をカットする。これにより、一枚の板を第１板４１と第２板４２とに分割することができる。次に、底面にフッ素樹脂テープが貼り付けられた水槽用蓋４の外形枠（本実施形態においては、矩形枠）に、ヒンジ部４３を設けるための隙間を空けて第１板４１と第２板４２とを並べる。そして、第１板４１と第２板４２との隙間に液状の弾性材を流し込む。その後、液状の弾性材が硬化する前に、先端が丸まった棒などを液状の弾性材の上部に押し当てて凹み４３１を形成する。その結果、液状の弾性材が硬化することにより、ヒンジ部４３を形成することができ、水槽用蓋４を製造することができる。 First, a plate is prepared and a portion where the hinge portion 43 is to be provided is cut. Thereby, one plate can be divided into the first plate 41 and the second plate 42 . Next, the first plate 41 and the second plate 41 are separated from the outer frame (rectangular frame in this embodiment) of the aquarium lid 4 having the bottom surface of which the fluororesin tape is attached, with a gap for providing the hinge portion 43 . The plate 42 is arranged side by side. Then, a liquid elastic material is poured into the gap between the first plate 41 and the second plate 42 . Thereafter, before the liquid elastic material hardens, a rod or the like with a rounded end is pressed against the upper portion of the liquid elastic material to form a recess 431 . As a result, the liquid elastic material hardens, whereby the hinge portion 43 can be formed, and the aquarium lid 4 can be manufactured.

ヒンジ部４３を弾性材で形成することにより、例えば、第１板４１が不要な場合などにヒンジ部４３をカットして水槽用蓋４から第１板４１を取り除くことができる。 By forming the hinge portion 43 from an elastic material, for example, when the first plate 41 is unnecessary, the hinge portion 43 can be cut and the first plate 41 can be removed from the aquarium cover 4 .

以上より、本実施形態に係る水槽用蓋４は、第１板４１と、第２板４２と、第１板４１と第２板４２とを回動可能に連結するヒンジ部４３と、を備え、第１板４１及び第２板４２は、それぞれの上面４１ａ，４２ａが実質的に面一となるようにヒンジ部４３に連結され、ヒンジ部４３は、弾性材で形成され、ヒンジ部４３の上面４３ａは、第１板４１及び第２板４２のそれぞれの上面４１ａ，４２ａと実質的に面一又はより凹んでいる、という構成が好ましい。 As described above, the aquarium lid 4 according to the present embodiment includes the first plate 41, the second plate 42, and the hinge portion 43 that rotatably connects the first plate 41 and the second plate 42. , the first plate 41 and the second plate 42 are connected to the hinge portion 43 so that the respective upper surfaces 41a and 42a are substantially flush with each other. Preferably, the upper surface 43a is substantially flush with or recessed from the upper surfaces 41a and 42a of the first plate 41 and the second plate 42, respectively.

斯かる構成によれば、ヒンジ部４３の上面４３ａが第１板４１及び第２板４２のそれぞれの上面４１ａ，４２ａと実質的に面一又はより凹んでいることにより、ヒンジ部４３を目立ち難くすることができる。これにより、水槽用蓋４の見栄えを良くすることができる。また、ヒンジ部４３の上面４３ａが第１板４１及び第２板４２のそれぞれの上面４１ａ，４２ａと実質的に面一又はより凹んでいることにより、例えば、ヒンジ部４３に物が当たり、水槽用蓋４がずれることを防ぐことができる。 According to such a configuration, the upper surface 43a of the hinge portion 43 is substantially flush with or recessed from the upper surfaces 41a and 42a of the first plate 41 and the second plate 42, respectively, thereby making the hinge portion 43 inconspicuous. can do. Thereby, the appearance of the water tank cover 4 can be improved. In addition, since the upper surface 43a of the hinge portion 43 is substantially flush with or recessed from the upper surfaces 41a and 42a of the first plate 41 and the second plate 42, for example, an object hits the hinge portion 43, It is possible to prevent the lid 4 from slipping.

また、本実施形態に係る水槽用蓋４において、ヒンジ部４３は、第１板４１と第２板４２との間を埋めるように連続して延びている、という構成が好ましい。 Further, in the aquarium lid 4 according to the present embodiment, it is preferable that the hinge portion 43 continuously extend so as to fill the space between the first plate 41 and the second plate 42 .

斯かる構成によれば、第１板４１と第２板４２との間に隙間が生じることを防ぐことができる。これにより、例えば、第１板４１と第２板４２との間から虫などの小生物や観賞魚などが水槽１から脱走や侵入することを防ぐことができる。また、第１板４１と第２板４２との間に隙間が生じることを防ぐことにより、水槽１内の気密性を高めることができ、水の蒸発によって水槽１内の水位が下がることを防止することができる。 With such a configuration, it is possible to prevent a gap from forming between the first plate 41 and the second plate 42 . As a result, for example, it is possible to prevent small creatures such as insects and ornamental fish from escaping or entering the water tank 1 from between the first plate 41 and the second plate 42 . In addition, by preventing the formation of a gap between the first plate 41 and the second plate 42, the airtightness in the water tank 1 can be improved, and the water level in the water tank 1 can be prevented from dropping due to water evaporation. can do.

また、本実施形態に係る水槽用蓋４において、ヒンジ部４３は、第１板４１及び第２板４２のそれぞれの上面４１ａ，４２ａより凹んだ凹み４３１を備える、という構成が好ましい。 Further, in the aquarium lid 4 according to the present embodiment, it is preferable that the hinge portion 43 has a recess 431 recessed from the upper surfaces 41a and 42a of the first plate 41 and the second plate 42, respectively.

斯かる構成によれば、ヒンジ部４３を凹み４３１側に変形しやすくすることができる。これにより、第１板４１を一方向（凹み４３１側）に開きやすくすることができる。 With such a configuration, the hinge portion 43 can be easily deformed toward the recess 431 . Thereby, the first plate 41 can be easily opened in one direction (the recess 431 side).

本実施形態に係る水槽１は、上端に開口３ａを有する側壁３と、水槽用蓋４と、を備え、水槽用蓋４は、開口３ａを塞ぐように側壁３の上端に載置される、という構成が好ましい。 The water tank 1 according to this embodiment includes a side wall 3 having an opening 3a at its upper end, and a water tank lid 4. The water tank lid 4 is placed on the upper end of the side wall 3 so as to close the opening 3a. is preferable.
