PROBLEM TO BE SOLVED: To provide an automatic scattering device in a storage body which automatically scatters a spray solution and the like into the storage body whenever an opening/closing tool such as a door, a lid and the like of the storage body is opened/closed.SOLUTION: A spray liquid scattering device 100A installed with a spray liquid storing portion 100, a push button 202, and a spray liquid discharging mechanism 200 is detachably attached to an opening/closing tool 2 of a storage body or the storage body 1 itself. A press-in operating mechanism 300A for pressing in the push button and releasing the pressing-in by the opening/closing action of the opening/closing tool, is provided on the spray liquid discharging mechanism. The press-in operating mechanism is composed of an operation arm 310 with a cam which can abut on and separate from the opening/closing tool at a tip end, and formed with a taper cam 311b for slidably contacting with a head of the push button to press in the push button and release the pressing-in, on a body portion a spring mechanism 320b for energizing the operation arm with the cam so as to enable reciprocatingly sliding and a frame body 330 formed with a scattering opening portion 311, and detachably attached to an upper part of the spray liquid storing portion 100.COPYRIGHT: (C)2015,JPO&INPIT【課題】収容体の扉や蓋等の開閉具を開閉するのみで、その都度自動的に散布液等を収容体内に散布する収容体内自動散布装置を提供する。【解決手段】散布液収容部100と、押しボタン202と散布液吐出機構200を装着した散布液散布装置100Aを、収納体の開閉具2又は収納体1自体に着脱可能に装着し、開閉具の開閉作動により押しボタンの押し込みとその解除を操作する押し込み操作機構300Aを散布液吐出機構に併設し、押し込み操作機構は、先端部を開閉具に当接離間可能にし、押しボタンのヘッドに摺動接触して押しボタンの押し込みとその解除をするテーパーカム311bを胴部に形成したカム付操作アーム310と、カム付操作アームを付勢して往復摺動を可能にしたばね機構320bと、散布用開口部311を形成して散布液収容部100の上部に着脱可能に装着した枠体330とからなる。【選択図】図1
