WRITING INSTRUMENT CASE

PROBLEM TO BE SOLVED: To provide a writing instrument case capable of increasing the number of writing instruments to be housed therein, preventing pens, etc. from coming out in a vertical direction when not used, and standing in a center-spread state.SOLUTION: Right/left housing faces include a first housing chamber 5 and a second housing chamber 6, respectively. In the right/left first housing chambers 5, a recess 51 and a protrusion 52 are formed by folding a material in a zigzag shape with an opened upper side at a lower part of the right/left housing faces. When a writing instrument case 1 is folded in a folding line 3, the recess 51 and protrusion 52 of the right/left housing faces engage with each other. The right/left second housing chambers 6 are in an upper part of the right/left housing faces, are positioned not to be superimposed on each other when the writing instrument case 1 is folded in the folding line 3, and prevent articles housed in the first housing chambers 5 from coming out.SELECTED DRAWING: Figure 1 【課題】筆記具の収納本数を増やし、不使用時に上下方向にペンなどが抜け出ることを阻止し、見開き状に起立させることもできる筆記具ケースを提供する。【解決手段】左右の収納面は、それぞれが第１収納室５と第２収納室６を有する。左右の第１収納室５は、左右収納面の下部において、上方を開口させつつ、素材をジグザグ状に折り曲げて凹凸部５１，５２を形成したものである。筆記具ケース１が折り目３で折り畳まれたとき、それぞれの凹凸部分５１，５２が互いにかみ合う。左右の第２収納室６は、左右収納面の上部にあり、筆記具ケース１が折り目３で折り畳まれたときも重ならない位置にあると共に、第１収納室５に収納した物品が抜け出ることを阻止する。【選択図】図１
