Description

本発明は、医療研究や各種実験などに用いられるマウスなどの小動物を飼育するための飼育装置に関し、特に飼育装置に使用される密封手段に関するものである。 The present invention relates to a breeding apparatus for breeding small animals such as mice used for medical research and various experiments, and more particularly to a sealing means used for the breeding apparatus.

医療研究や各種実験などに用いられるマウスは、無菌環境で飼育しなければならないため、飼育装置自体あるいは飼育装置は密封状態とする必要があり、密封状態を確実に確保するためには、飼育容器と該開口を覆う蓋体とを密封手段であるOリングを強い力で挟持する必要があった。 Since mice used for medical research and various experiments must be bred in a sterile environment, the breeding device itself or the breeding device must be sealed. It was necessary to sandwich the O-ring as sealing means with a strong force between the cover and the lid covering the opening.

しかし、係る従来の方法では、内部の清掃などのために密封状態を解除するには、挟持手段を解除し、強い力で引き抜かなければならず手間がかかった。 However, in such a conventional method, in order to release the sealed state for cleaning the inside or the like, it is necessary to release the holding means and to pull out with a strong force.

このような問題点を解決する手段として、特許文献１では、Oリングに替え、半径方向に突出し、且つ他方の部材に接触して曲がるリップを有するガスケットが提案されている。かかる構成によれば、比較的小さな力で密封の脱着が可能となる。 As means for solving such a problem, Patent Literature 1 proposes a gasket having a lip that protrudes in the radial direction and is bent in contact with the other member instead of the O-ring. According to this configuration, the sealing can be detached and attached with a relatively small force.

しかし、上記手段ではリップの突出方向は半径方向外側に限られ、密封状態をさらに強固にするためリップを多数設けることも困難であった。また、一条のリップでは保持力が弱く、飼育容器と蓋体とは、クリップなどを用いて係止する必要があった However, in the above-mentioned means, the protruding direction of the lip is limited to the outer side in the radial direction, and it is difficult to provide a large number of lips in order to further strengthen the sealing state. In addition, the holding power of the single lip was weak, and the breeding container and the lid had to be locked using a clip or the like.

特許第５０６８９６２号Patent No. 5068962

本発明の課題は、比較的小さな力で脱着が可能で、かつ、取り付け方向に制限がなく、複数のリップの形成も容易な、飼育装置の密封手段を提供することである。 An object of the present invention is to provide a sealing means for a breeding apparatus, which can be attached and detached with a relatively small force, has no restriction on the mounting direction, and can easily form a plurality of lips.

本発明者らは、シール部材を環状帯体とし、その両端部をシールすべき部材の片方に固定すれば、シール部材を強固に部材に固定することができ、リップも複数形成することが容易となることを想到し、本発明に至った。 The present inventors can fix the seal member to the member by forming the seal member as an annular band and fixing both ends thereof to one of the members to be sealed, and easily form a plurality of lips. Thus, the present invention has been made.

本発明の実施の態様は以下のとおりである。
（１）一面が開口する飼育容器と該開口を覆う蓋体からなる飼育装置において、
前記飼育容器の端部と前記蓋体の端部の何れか一方が他方の内側に配置され、両者の間に介在するシール部材により密封されるよう構成されており、
前記シール部材は、環状の帯体からなり、その一端が湾曲して前記いずれか一方の端部の縁が嵌合する第１の凹部が形成され、該第一の凹部が形成される面とは逆の面に、他の端部と接触するリップが形成され、
前記第１の凹部に嵌合する端部には、前記シール部材の他端が嵌合する第２の凹部が形成されていることを特徴とする飼育装置の密封手段。
（２）他の端部と接触するリップが複数設けられている、（１）の密封手段。
（３）前記第２の凹部には、複数個の貫通孔が設けられ、該貫通孔に対応するシール部材には該貫通孔を貫通する、先端に膨張部が形成された突起が設けられている（１）または（２）の密封手段。 Embodiments of the present invention are as follows.
(1) In a breeding apparatus comprising a breeding container having an opening on one side and a lid covering the opening,
Either one of the end of the breeding container and the end of the lid is arranged inside the other, and is configured to be sealed by a seal member interposed therebetween.
The sealing member is formed of an annular band body, one end of which is curved to form a first recess in which an edge of one of the ends is fitted, and a surface on which the first recess is formed. Has a lip on the opposite side that contacts the other end,
The sealing means of the breeding apparatus, wherein a second concave portion is formed at an end portion of the breeding device, the second concave portion being fitted to the other end of the seal member.
(2) The sealing means according to (1), wherein a plurality of lips contacting the other end are provided.
(3) The second recess has a plurality of through-holes, and a seal member corresponding to the through-hole is provided with a projection having an inflatable portion formed at the tip end, penetrating the through-hole. (1) or (2) sealing means.

本発明におけるシール部材は、十分な弾性を有してシール性に優れ、高熱殺菌に耐え得る耐熱性を備えていれば種類を問わず、加工に優れたシリコングムなどが好適に使用できる。 Regardless of the type of the seal member of the present invention, any type of silicon gum which is excellent in processing can be suitably used as long as it has sufficient elasticity, excellent sealability, and heat resistance enough to withstand high-temperature sterilization.

本発明の密封手段によれば、シール部材を帯体としたので、密封状態を形成するリップを複数形成でき、密封度を高めることができる。また、帯体の上下端がシールすべき部材の片方に固定されているので、シール部材が強固にシールすべき部材に固定され、シールすべき部材の内側にも外側にも取り付けることも可能である。さらに、リップを複数形成することで飼育容器と蓋体とを十分な強度で係止することができ、別途の係止手段を省略できる。 According to the sealing means of the present invention, since the sealing member is a band, a plurality of lips for forming a sealed state can be formed, and the degree of sealing can be increased. In addition, since the upper and lower ends of the band are fixed to one of the members to be sealed, the sealing member is firmly fixed to the member to be sealed, and it is possible to attach the inside and outside of the member to be sealed. is there. Furthermore, by forming a plurality of lips, the rearing container and the lid can be locked with sufficient strength, and a separate locking means can be omitted.
