本考案は粉体現像剤用容器に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a container for powder developer.
一般に電子写真法、静電印刷法等において形成
された静電荷潜像は、適当な現像器においてトナ
ーと称する現像剤によつて現像されることにより
可視画像が形成される。而して現像剤は現像の度
毎に消費されるものであるから、定期的に現像器
の現像剤タンク内に現像剤を補給することが必要
である。そして、必要となつたときには所要量の
現像剤を直ちに補給することができるよう、現像
剤用容器内に所要量の現像剤を充填してこれを現
像器の近辺に準備しておくことが望ましい。 Generally, an electrostatic latent image formed by an electrophotographic method, an electrostatic printing method, or the like is developed into a visible image by being developed with a developer called a toner in a suitable developing device. Since the developer is consumed every time development is performed, it is necessary to periodically replenish the developer tank of the developing device. In order to be able to immediately replenish the required amount of developer when needed, it is desirable to fill a developer container with the required amount of developer and prepare it near the developing device. .
従来この種の現像剤用容器としては、壜形或い
は筒状の容器本体とこの容器本体の一端開口を塞
ぐ蓋部材とより成るものが用いられている。 Conventionally, this type of developer container has been used, which consists of a bottle-shaped or cylindrical container body and a lid member that closes an opening at one end of the container body.
一方、静電荷潜像を現像するための現像剤とし
ては液体現像剤と粉体現像剤とが知られているが
近年においては種々の点から粉体現像剤が多く用
いられるに至つている。然るにこの粉体現像剤に
ついて用いる場合に、従来の現像剤用容器におい
ては次のような欠点がある。 On the other hand, liquid developers and powder developers are known as developers for developing electrostatic latent images, but in recent years, powder developers have come into widespread use for various reasons. However, when using this powder developer, conventional developer containers have the following drawbacks.
即ち、現像器の現像剤タンクにおける現像剤注
入口は、例えば電子写真複写機における現像器に
見られるように、装置をコンパクトとする必要性
及び複写機等に現像剤を注入するとき２〜30ミリ

のため現像剤用容器の開口をそれに応じて小さな
口径とすることが必要である反面、開口の口径が
小さいと当該容器内に粉体現像剤を充填すること
が非常に困難となる。即ち前述した通り現像剤の
粒径が２〜30ミクロンという微粉であるためブリ
ツジ現象といつた現像剤づまりを生じ徒に周辺に
散乱し、少量づつしか現像剤の充填が行なわれ
ず、充填に長時間を要するばかりでなく、飛散に
よる損失が多くかつ周辺を汚染するという弊害が
ともなう。他方容器の開口部を大きくすると現像
剤の充填は容易になるが前記の理由で現像器への
注入が困難になるなどの難点があつた。 In other words, the developer inlet in the developer tank of the developer is required to have a diameter of 2 to 30 mm when injecting developer into a copying machine, etc. due to the need to make the device compact, as seen in the developer in an electrophotographic copying machine, for example. Because fine toner powder of millimicrons is scattered in the form of smoke and contaminates surrounding equipment, it is usually made with a fairly small diameter or narrow diameter, so the opening of the developer container must be made small accordingly. On the other hand, if the diameter of the opening is small, it becomes very difficult to fill the container with powder developer. That is, as mentioned above, since the developer is a fine powder with a particle size of 2 to 30 microns, developer clogging, known as a bridging phenomenon, occurs and is unnecessarily scattered around the area. Not only is it necessary, but it also has the disadvantage of causing a lot of loss due to scattering and contaminating the surrounding area. On the other hand, if the opening of the container is made larger, it becomes easier to fill the developer, but there is a problem in that it becomes difficult to pour the developer into the developer for the reasons mentioned above.
本考案は以上の如き点に鑑み、粉体現像剤の充
填を容易にかつ円滑に達成することができると共
に、現像器の現像剤タンクへの注入を、他の器具
を用いることなく好適に達成することのできる粉
体現像剤用容器を提供することを目的とする。 In view of the above points, the present invention can easily and smoothly fill the powder developer, and can suitably achieve injection into the developer tank of the developer without using any other equipment. It is an object of the present invention to provide a container for powder developer that can be used as a powder developer.
さらに他の目的は粉体現像剤用容器が使用され

る。 Another purpose is to prevent the powder developer container from loosening due to vibration during use or transportation, and to prevent the developer from flowing out of the container or deteriorating due to moisture. The purpose of the present invention is to provide a powder developer container that will never cause problems.
以下本考案を実施例により具体的に説明する

の作用も有している。 As shown in FIG. 1, a large-diameter opening 2 for filling powder developer is formed at one end of a cylindrical container body 1 made of polyethylene, for example, and a recess is formed on the outer circumferential surface of a cylindrical portion 1A continuing from this one end. 1B is formed.
Further, a base end cylinder part 3A having an inner diameter matching the outer diameter of the cylinder part 1A of the container body 1, and a front end cylinder part 3B having a small diameter opening 4 for discharging the powder developer formed at the front end thereof. An inner lid 3 made of polyethylene, for example, is provided, and includes a funnel-shaped intermediate portion 3C that connects the proximal tube portion 3A and the distal tube portion 3B, and the recess 1B is provided on the inner circumferential surface of the proximal tube portion 3A. Convex part 3 that engages with
D and protrusions 3F are formed to tightly fit the proximal end cylinder part 3A into the cylinder part 1A of the container body 1, and for example, the slopes of the protrusions and recesses on the opening side of the main body 1 are made gentler. It is fixed in such a way that it cannot be easily removed by making the slope of the bottom part steeper, and a screw 3E is formed on the outer circumferential surface of the tip tube part 3B. Then, an upper lid 5 is provided which is screwed onto the screw 3E, tightly fits into the tip tube portion 3B, and closes the opening 4, thereby forming a powder developer container. Note that the 3F has the function of making the fitting of the concave portion and the convex portion more reliable, and also of preventing the developer from flowing into the fitting portion.

ることができ、この状態で現像器の近傍に備えて
おくことができる。 Since the powder developer container of the present invention has the above-described structure, the large diameter opening 2 of the container body 1 is open when the inner lid 3 is not fitted and fixed.
Therefore, the powder developer can be filled through the opening 2, and as a result, the powder developer can be filled extremely smoothly without scattering, loss, bridging, etc. of the developer caused by using a small-diameter developer filling port. Furthermore, it is possible to fill the required amount of powder developer within a short period of time. After filling, the base end cylindrical portion 3A of the inner lid 3 is tightly fitted and fixed to the cylindrical portion 1A of the container body 1,
Further, by tightly fitting the upper lid 5 to the tip tube portion 3B, the filled powder developer can be sealed, and in this state it can be kept near the developing device.

たり飛散したりして周辺を汚損することがない。 When replenishing the developing device with the powder developer in the container, the upper lid 5 is removed from the tip tube portion 3B of the inner lid 3 to open the small-diameter opening 4, and the opening 4 is connected to the developer tank of the developing device. The powder developer inside is discharged from the opening 4 by tilting the entire container upside down and rotating the container around its central axis in this state. The agent can be injected through the inlet. Therefore, even if the developer injection port has a small diameter or a narrow one, since the opening 4 has a small diameter, powder developer can be reliably injected and replenished without using any other equipment such as a funnel. This prevents the developer from spilling or scattering and staining the surrounding area.

も容器本体１の材質として好ましいものである。 In the present invention, the container body 1, inner lid 3, and upper lid 5 may be made of any material, but plastic is preferred from the viewpoints of preserving the powder developer content, light weight, ease of mass production, and cost. It is preferable to use the material. In particular, the container body 1 and the inner lid 3 are made of polyethylene and have high sliding properties against the powder developer, so the powder developer can be discharged extremely smoothly and without leaving any residue inside the container. You can force it. Furthermore, by making the container body 1 transparent or translucent, it is possible to visually confirm the presence or absence of powder developer and the remaining amount when not all is discharged in one replenishment. Since polyethylene is usually translucent, it is also preferable as a material for the container body 1 in this respect.

い円筒状とすることが好ましい。 Further, the container body 1 may have a cylindrical shape, but if it is a rectangular cylindrical shape, the flat part that is held by the hand when discharging the powder developer is likely to be deformed inwardly, and in this case, the powder developer will be rapidly removed. There is a risk that the developer may spray out and scatter, and furthermore, the corner of the inner wall becomes a dead point and the developer tends to remain. For these reasons, it is preferable to have a cylindrical shape that provides high rigidity, is difficult to deform, and has no dead points.

After the D side is fitted with a simple plane, it may be heat-fused by high frequency heating or the like, or it may be bonded using an adhesive at the time of fitting. Originally, the present invention relates to an improvement of the specification of Utility Application No. 54-53368, which was previously proposed by the applicant. In this case, the purpose is to eliminate problems such as leakage of developer due to loosening of the inner lid during operation or transportation, and the scattering of developer by opening the inner lid and injecting developer into the developing device. It is something that

いう利点がある。 That is, in the present invention, since the inner lid 3 is fixed to the container body 1 by a fitting method, a fusion method, an adhesive method, etc. using the engagement of the convex portion and the concave portion, the inner lid 3 is fixed to the container body 1. After filling the developer through the large-diameter opening 2, the inner lid 3
This has the advantage that accidents such as opening the inner lid by mistake due to not being able to remove it from the main body 1 are completely eliminated, and also accidents such as the inner lid coming loose during transportation are completely eliminated.
又上蓋５については、粉体現像剤の全部を１回
の補給で排出せしめない場合もあるから、任意に
嵌合、取外しが可能なものとしておくのが好まし
い。 As for the upper lid 5, it is preferable that the upper lid 5 be able to be fitted and removed as desired, since there are cases where not all of the powder developer is discharged in one replenishment.
