Japanese Patent No. 277038

しかしながら、前記従来の電気掃除機用集塵袋の遮蔽板は、これを構成するシート自体は破断に対して強く構成されているが、シートが薄く軟質であって剛性がかなり低いので、前記固定片と折り返し片とで形成されて前記遮蔽片が収納される収納部は、筒状または断面コの字状に形成されていても、上下部が開口されており、集塵袋の支持板に取り付けられるまでは、全体として保形性が悪く変形し易い。そのため、取り扱い難くて集塵袋の支持板に取り付ける作業が厄介であると共に、前記遮蔽片の下部が収納部からその外側下方に突き出しているので、集塵袋を電気掃除機に装着する際に、前記遮蔽片の下部が邪魔になるおそれがある。また、前記折り返し片が前記集塵袋の支持板に取り付けられ、遮蔽片を有する固定片が前記支持板に対して自由状態となっているので、遮蔽片を収納部から強く引き出すと、固定片の下辺が支持板から離れて、支持板の塵埃導入口の閉鎖が不完全となるおそれがある。さらに、前記遮蔽板は、集塵袋に取り付けて市販することを前提としており、前記のとおり変形し易いので包装等も簡単に行うことができず、それ自体、単独の商品として流通させることができない等の不満がある。   However, the shielding plate of the conventional dust bag for a vacuum cleaner is configured so that the sheet itself constituting it is strong against breakage, but the sheet is thin and soft and has a considerably low rigidity. Even if the storage part that is formed of a piece and a folded piece and stores the shielding piece is formed in a cylindrical shape or a U-shaped cross-section, the upper and lower parts are opened, and the support part of the dust collection bag Until it is attached, the overall shape retention is poor and it tends to deform. For this reason, it is difficult to handle and the work of attaching to the support plate of the dust bag is troublesome, and the lower part of the shielding piece protrudes outward from the storage part, so when attaching the dust bag to the vacuum cleaner The lower part of the shielding piece may get in the way. Further, since the folded piece is attached to the support plate of the dust bag and the fixed piece having the shielding piece is in a free state with respect to the support plate, There is a possibility that the lower side of the support plate is separated from the support plate and the dust inlet of the support plate is not completely closed. Further, the shielding plate is presupposed to be marketed by being attached to a dust bag, and as described above, since it is easily deformed, packaging and the like cannot be easily performed, and the product itself can be distributed as a single product. There is dissatisfaction such as being impossible.

本発明は、上記事情に鑑みてなされたものであって、十分に保形性を確保することができて、単独の商品として流通させることができると共に、集塵袋への取り付けも容易に行える電気掃除機用集塵袋の遮蔽ユニットおよびこれを取り付けた電気掃除機用集塵袋を提供することを目的とする。   The present invention has been made in view of the above circumstances, can sufficiently ensure shape retention, can be distributed as a single product, and can be easily attached to a dust bag.

次に、前記シートＳから遮蔽ユニット１を形成するには、先ず、図４に示すように展開された状態のシートＳにおける遮蔽片４を、図５に示すように、第２の折り返し線ｓ２で紙面に垂直に手前方向に折り返してから、上方に固定片２の手前側（内側）に沿うように折り返し、しかる後に、第３の折り返し線ｓ３の開始線ｓ３ａで前記と反対方向に折り返し、順次、第３の折り返し線ｓ３の終端線ｓ３ｆに至るまで各折り返し線ｓ３ｂ〜３ｅで交互に（ジグザグに）折り返すことにより折り返し部５ａを形成して、該折り返し部５ａが、前記最初の折り返し部５ａ１を固定片２から離れた側に位置され、順に固定片２に接近する側へ向けて折り重ねられ、前記固定片２の他辺ｘ（図４の下辺）に沿わされた状態とし、前記操作部６が前記固定片２の手前側に平行に沿って固定片２の前記他辺ｘの対向辺側に延長され、前記操作部６の摘み部６ｂが前記対向辺から上方へ突き出された状態とする。なお、前記第３の折り返し線ｓ３における各折り返し線ｓ３ａ〜ｓ３ｆの部分には、前記折り返し部５ａの折り返し作業を容易に行えるように、極く細いミシン目を設けてもよい。   Next, in order to form the shielding unit 1 from the sheet S, first, the shielding piece 4 in the unfolded sheet S as shown in FIG. 4 is replaced with the second folding line s2 as shown in FIG. And then folded back to the front side (inner side) of the fixed piece 2 and then folded back in the opposite direction to the start line s3a of the third folding line s3. Sequentially, each folded line s3b-3e is folded back (zigzag) until it reaches the terminal line s3f of the third folded line s3 to form a folded part 5a, and the folded part 5a is the first folded part. 5a1 is located on the side away from the fixed piece 2, is folded in order toward the side closer to the fixed piece 2, and is in a state along the other side x of the fixed piece 2 (the lower side in FIG. 4), The operation unit 6 is fixed. Extending on opposite sides of the other side x of the fixed piece 2 along parallel to the second front side, a state where the knob portion 6b of the operation portion 6 is projected upward from the opposite sides. It should be noted that extremely thin perforations may be provided at the portions of the return lines s3a to s3f in the third return line s3 so that the return operation of the return part 5a can be easily performed.

次に、上記状態を保持しながら、前記カバー片３を前記第１の折り返し線ｓ１で紙面の手前側に垂直に折り返してから、さらに固定片２の内側に平行に沿うように折り返し、前記遮蔽部５の最初の折り返し部５ａ１の裏面側に接着剤ｇを塗布して、前記カバー片３の下辺ｘ１を前記最初の折り返し部５ａ１の裏面側に接着する。しかる後に、前記カバー片３の糊しろ３ｂの接着面３ｂ１に接着剤ｇを塗布し、折り返し線ｓ４で固定片２の裏面側へ折り返して、該固定片２の裏面に前記糊しろ３ｂを接着する。   Next, while holding the above state, the cover piece 3 is folded back vertically toward the front side of the paper surface along the first fold line s1, and then folded back along the inner side of the fixed piece 2 so that the shielding is performed. Adhesive g is applied to the back side of the first folded part 5a1 of the part 5, and the lower side x1 of the cover piece 3 is adhered to the back side of the first folded part 5a1. After that, the adhesive g is applied to the adhesive surface 3b1 of the adhesive margin 3b of the cover piece 3, folded back to the back surface side of the fixed piece 2 along the folding line s4, and the adhesive margin 3b is adhered to the rear surface of the fixed piece 2. To do.

これにより、図１〜図３に示すように、前記固定片２とカバー片３とがそれらの左右両辺と下辺ｘ，ｘ１側の三辺を閉じられて袋状に形成され、その内側の収納部１ａに、底部側に折り重ねられた遮蔽部５ａを位置させ、第３の開口部６ａを前記固定片２とカバー片３の第１、第２の開口部２ａ，３ａに連通させた状態とし、前記操作部６を固定片２の内側面に沿わせ、摘み部６ｂを前記収納部１ａの開放側から上方（外側）へ突き出した状態とした遮蔽片４が収納されてなる遮蔽ユニット１が構成される。そして、前記摘み部６ｂを介して前記操作部６を前記収納部１ａから引き出すことにより、前記遮蔽部５で前記第１の開口部２ａを閉鎖し得るようになっている。
なお、前記のように構成された遮蔽ユニット１は、図１で上下方向の高さ寸法および左右方向の幅寸法が、市販の電気掃除機用集塵袋ｐの口紙ｐ１のいずれにも好適に取り付け得る大きさに設定されている。
Thereby, as shown in FIGS. 1 to 3, the fixed piece 2 and the cover piece 3 are formed in a bag shape with their left and right sides and the three sides on the lower side x, x1 side being closed. The shield 5a folded on the bottom side is positioned on the part 1a, and the third opening 6a communicates with the first and second openings 2a and 3a of the fixed piece 2 and the cover piece 3. And a shielding unit 1 in which the shielding piece 4 is housed in such a manner that the operation portion 6 is placed along the inner surface of the fixed piece 2 and the knob portion 6b protrudes upward (outside) from the open side of the housing portion 1a. Is configured. Then, the first opening 2a can be closed by the shielding part 5 by pulling out the operation part 6 from the storage part 1a via the knob part 6b.
In addition, the shielding unit 1 configured as described above has a height dimension in the vertical direction and a width dimension in the horizontal direction in FIG. 1 that is suitable for any of the cover p1 of the dust collecting bag p for a commercial vacuum cleaner. It is set to a size that can be attached to.

このように構成された遮蔽ユニット１は、図６、図７に示すように、電気掃除機様集塵袋Ｐの口紙ｐ１の塵埃導入口ｐ２に前記固定片２の第１の開口部２ａを、それらの中心が一致するように連通させて、固定片２をその裏面側を前記口紙ｐ１の前面に接着して該口紙ｐ１に取り付ける。
このように遮蔽ユニット１が取り付けられた電気掃除機用集塵袋Ｐにおいては、図６に示すように、前記遮蔽ユニット１がその収納部１ａに遮蔽片４が収納された状態で、電気掃除機の集塵室に装着して使用される。その装着の際には、前記遮蔽ユニット１が三方を閉じた袋状に形成され、その収納部１ａ内に遮蔽片４が摘み部６ｂのみを除いて完全に収納された状態となっており、遮蔽ユニット１の下方に遮蔽片４が障害物の如く突き出していないので、支障無く円滑、確実に集塵室に装着することはできる。 As shown in FIGS. 6 and 7, the shielding unit 1 configured in this way has a first opening 2 a of the fixed piece 2 in the dust introduction port p <b> 2 of the cover paper p <b> 1 of the vacuum cleaner-like dust collection bag P. Are connected so that their centers coincide with each other, and the fixing piece 2 is attached to the front cover p1 by adhering the back surface thereof to the front face of the front cover p1.
In the vacuum cleaner dust collection bag P to which the shielding unit 1 is attached in this way, as shown in FIG. 6, the shielding unit 1 is in a state where the shielding piece 4 is housed in the housing portion 1a. Used in the dust collection chamber of the machine. At the time of mounting, the shielding unit 1 is formed in a bag shape with three sides closed, and the shielding piece 4 is completely housed in the housing portion 1a except for the knob portion 6b. Since the shielding piece 4 does not protrude like an obstacle below the shielding unit 1, it can be smoothly and surely attached to the dust collecting chamber without any trouble.

電気掃除機が繰り返し使用されることにより前記集塵袋Ｐに塵埃が満杯になったときには、前記集塵袋Ｐを集塵室から取り出す前に、集塵室内に突出している集塵パイプと前記口紙ｐ１の塵埃導入口ｐ２との嵌合を外した状態として、図７に示すように、前記摘み部６ｂを掴んで遮蔽片４の操作部６を前記収納部１ａから上方へ引き抜く（引き出す）。これにより、該操作部６が前記固定片２とカバー片３とに沿って上方へ移動されて、前記遮蔽部５の折り返し部５ａが固定片２の内面に接する側から順に折り返しを解かれながら上方へ引き上げられ、前記閉鎖部５によって前記第１の開口部２ａ、口紙ｐ１の塵埃導入口ｐ２が閉鎖される。このように前記口紙ｐ１の塵埃導入口ｐ２を遮蔽部５で閉鎖してから、前記集塵袋Ｐを電気掃除機の集塵室から取り出すことにより、集塵袋Ｐに回収された塵埃が外部に漏れるのを確実に防止することができる。   When the dust bag P becomes full due to repeated use of an electric vacuum cleaner, the dust collection pipe projecting into the dust chamber and the dust collecting pipe P are removed before the dust bag P is taken out of the dust chamber. As shown in FIG. 7, with the state where the cover p1 and the dust introduction port p2 are disengaged, as shown in FIG. 7, the operating portion 6 of the shielding piece 4 is pulled out (drawn) from the storage portion 1a by grasping the knob portion 6b. ). As a result, the operating portion 6 is moved upward along the fixed piece 2 and the cover piece 3, and the folded portion 5 a of the shielding portion 5 is unfolded sequentially from the side in contact with the inner surface of the fixed piece 2. The first opening 2 a and the dust inlet p <b> 2 of the cover paper p <b> 1 are closed by the closing portion 5. Thus, after the dust inlet port p2 of the cover paper p1 is closed by the shielding part 5, the dust collected in the dust bag P is removed by removing the dust bag P from the dust collecting chamber of the vacuum cleaner. It is possible to reliably prevent leakage to the outside.

以上説明したように、前記第１の実施の形態に係る電気掃除機用集塵袋の遮蔽ユニット１は、電気掃除機用集塵袋Ｐの口紙ｐ１の塵埃導入口ｐ２に連通可能な第１の開口部２ａを有する矩形状の固定片２と、該固定片２の一辺ｙに第１の折り返し線ｓ１を介して接続され、前記第１の開口部２ａに連通可能な第２の開口部３ａを有するカバー片３と、前記固定片２の一辺ｙに直角な他辺ｘに第２の折り返し線ｓ２を介して接続され、該第２の折り返し線ｓ２に近い側に前記第１の開口部２ａを閉鎖可能な遮蔽部５を有し、前記第２の折り返し線ｓ２から離れた側に前記第１の開口部２ａに連通可能な第３の開口部６ａが設けられた操作部６を有する矩形状の遮蔽片４とを備えたシートＳが、前記各折り返し線ｓ１，ｓ２で折り返され、前記固定片２とカバー片３とにより三辺が閉じられた袋状に形成され、その内側の収納部１ａ内に前記遮蔽片４が収納されてなり、前記遮蔽片４が、前記遮蔽部を、前記第２の折り返し線ｓ２と平行な第３の折り返し線ｓ３によって表裏方向に複数回折り返されて、その折り返し部５ａを前記固定片２の他辺ｘの内側に沿って位置され、前記操作部６を、前記第３の開口部６ａが前記第１の開口部２ａの位置に合わせられ、前記折り返し部５ａの反対側の端部に設けた摘み部６ｂを前記収納部１ａの開放側から外側に突き出した状態で前記収納部１ａに収納されており、前記摘み部６ｂを介して前記操作部６を前記収納部１ａから引き出すことにより、前記遮蔽部５で前記第１の開口部２ａを閉鎖し得るように構成されている。   As described above, the vacuum cleaner dust bag shielding unit 1 according to the first embodiment can communicate with the dust introduction port p2 of the cover p1 of the vacuum cleaner dust bag P. A rectangular fixed piece 2 having one opening 2a, and a second opening connected to one side y of the fixed piece 2 via a first folding line s1 and communicating with the first opening 2a. The cover piece 3 having the portion 3a is connected to the other side x perpendicular to the one side y of the fixed piece 2 via the second fold line s2, and the first fold line is closer to the second fold line s2. An operating portion 6 having a shielding portion 5 capable of closing the opening portion 2a and provided with a third opening portion 6a capable of communicating with the first opening portion 2a on the side away from the second folding line s2. A sheet S provided with a rectangular shielding piece 4 having It is formed in a bag shape with three sides closed by the piece 2 and the cover piece 3, and the shielding piece 4 is accommodated in the accommodating portion 1a on the inside thereof, and the shielding piece 4 is used to A plurality of folding lines 5a are folded back and forth by a third folding line s3 parallel to the second folding line s2, and the folded part 5a is positioned along the inner side of the other side x of the fixed piece 2; The third opening 6a is aligned with the position of the first opening 2a, and the knob 6b provided on the opposite end of the folded portion 5a is moved outward from the open side of the storage portion 1a. The first opening 2a is closed by the shielding part 5 by being pulled out and stored in the storage part 1a, and by pulling out the operation part 6 from the storage part 1a via the knob 6b. Configured to get.

したがって、前記第１の実施の形態に係る電気掃除機用集塵袋の遮蔽ユニット１によれば、固定片２とカバー片３に設けられた一対の糊しろ３ｂ，５ａ１によって、固定片２とカバー片３とが結合されて三方が閉じられ、内側に遮蔽部５と操作部６を収納する収納部１ａが袋状に形成されているので、遮蔽ユニット１を形成するシートＳが薄くても、全体として剛性を高めて保形性を十分に確保して遮蔽ユニット１を強固に形成することができて、その取り扱いや包装等を容易に行うことができ、遮蔽ユニット１を単独の商品として流通させることができると共に、集塵袋Ｐへの取り付けも容易に行うことができる。
そして、前記遮蔽ユニット１を取り付けた電気掃除機用集塵袋Ｐによれば、遮蔽ユニット１が保形性を良好に確保された状態で集塵袋Ｐに容易にかつ正確に取り付けることができる。
その上、集塵袋Ｐの口紙ｐ１に固定される前記固定片２に遮蔽片４が接続され、該遮蔽片４が固定片２とカバー片３とにより収納部１ａの底部にしっかりと固定される構成となっているので、前記遮蔽片４を収納部１ａから強く引き抜いても、固定片２やカバー片３が変形する余地がなく、遮蔽片４の遮蔽部５による集塵袋Ｐの口紙ｐ１の塵埃導入口ｐ２の閉鎖を確実に行うことができる。 Therefore, according to the shielding unit 1 of the vacuum cleaner dust bag according to the first embodiment, the fixing piece 2 and the cover piece 3 are provided with the fixing piece 2 by the pair of paste margins 3b and 5a1. Since the cover piece 3 is coupled and the three sides are closed, and the storage portion 1a for storing the shielding portion 5 and the operation portion 6 is formed in a bag shape inside, even if the sheet S forming the shielding unit 1 is thin , The rigidity can be increased as a whole, the shape retention can be sufficiently secured and the shielding unit 1 can be formed firmly, and the handling and packaging can be easily performed, and the shielding unit 1 can be used as a single product. While being able to distribute | circulate, the attachment to the dust bag P can also be performed easily.
And according to the vacuum cleaner dust-collecting bag P to which the shielding unit 1 is attached, the shielding unit 1 can be easily and accurately attached to the dust-collecting bag P in a state in which the shape retaining property is well secured. .
In addition, a shielding piece 4 is connected to the fixed piece 2 fixed to the cover p1 of the dust bag P, and the shielding piece 4 is firmly fixed to the bottom of the storage portion 1a by the fixed piece 2 and the cover piece 3. Therefore, there is no room for deformation of the fixed piece 2 and the cover piece 3 even if the shielding piece 4 is strongly pulled out from the storage portion 1a, and the dust collecting bag P of the shielding piece 4 by the shielding portion 5 of the shielding piece 4 is not damaged. The dust introduction port p2 of the cover paper p1 can be reliably closed.

前記遮蔽ユニット１を単独の商品として流通させる場合には、前記固定片２の裏面（外面）に、両面接着剤が塗布され、該両面接着剤の露出面側にシール用フィルムが貼付された状態として遮蔽ユニット１が複数個まとめられて包装された構成とすると、使用者が使用時に包装から遮蔽ユニット１を取り出し、固定片２の裏面から前記シール用フィルムを剥がして、前記固定片２を、その第１の開口部２ａを市販の遮蔽板付きでない集塵袋Ｐの口紙ｐ１の塵埃導入口Ｐ２に合わせ、露出した接着剤によって前記口紙２ｐに接着させることにより、該遮蔽板付きでない集塵袋Ｐを容易に遮蔽板付きの電気掃除機用集塵袋Ｐに変換して使用することができる。   When distributing the shielding unit 1 as a single product, a state where a double-sided adhesive is applied to the back surface (outer surface) of the fixed piece 2 and a sealing film is attached to the exposed surface side of the double-sided adhesive As a configuration in which a plurality of shielding units 1 are packed together and packaged, the user takes out the shielding unit 1 from the packaging at the time of use, peels off the sealing film from the back surface of the fixing piece 2, and the fixing piece 2 By aligning the first opening 2a with the dust inlet P2 of the cover p1 of the dust collection bag P that is not commercially available with a shielding plate, and bonding it to the cover 2p with an exposed adhesive, the first opening 2a is not attached with the shielding plate. The dust bag P can be easily converted into a vacuum cleaner dust bag P with a shielding plate and used.
