Description

本発明は圧縮袋に付設する逆止弁および逆止弁を設けた圧縮袋に関するものである。     The present invention relates to a check valve attached to a compression bag and a compression bag provided with the check valve.

大きなものでは布団、小さなものでは旅行時の衣服等の脱気収納素材の容積を少なくして収納するときに使用される圧縮袋は、脱気収納素材を入れ、圧縮袋を圧縮して脱気した後、その出し入れ口を密閉するようにして使用するようにしてある。
ところが、こうしたものでは脱気収納素材を出し入れする出し入れ口を閉塞するときに、外気を吸引してしまうことから、操作が複雑でありながら、手早く行わなくてはならず、充分な圧縮効果を得ることが難しいという問題があった。 The compression bag used to store the deaeration storage material such as a futon for large items and the deaeration storage material such as clothes for travel for the small ones should be degassed by inserting the deaeration storage material and compressing the compression bag. After that, the inlet / outlet is used in a sealed state.
However, in such a case, since the outside air is sucked when the inlet / outlet for taking in / out the degassing storage material is closed, the operation must be performed quickly while obtaining a sufficient compression effect. There was a problem that it was difficult.

そこで、特許文献１に示されるように、圧縮袋内の空気を掃除機のノズルで吸引できる吸引口を表面に設けた逆止弁を圧縮袋に出し入れ口とは別に圧縮袋に取り付け楽に、手早く脱気できるようにしたものが先に提案されている
この特許文献１に記載の逆止弁は、排気口（本発明にいう第１通気孔）に配設した弁体をスプリングの弾性力によりで排気口を閉塞する方向に押圧付勢するように構成したもので、こうした圧縮袋内の排気時には、掃除機を必要とし掃除機のない旅先での使用時には、折り畳んだ圧縮袋を両手で強く大きな力で圧縮し、圧縮袋の内圧を高め、この高められた内圧により、スプリングの押圧付勢力に抗して弁体を上昇させなくてはならず、使いづらい上、圧縮袋の破れの原因になり、耐久性が低下してしまうという問題があった。
また、掃除機を使用する場合、吸引には強く大量の負圧を必要とすることから、掃除機への負荷も大きなものになってしまうという問題もある。 Therefore, as shown in Patent Document 1, a check valve provided on the surface with a suction port capable of sucking the air in the compression bag with the nozzle of the vacuum cleaner is put in and out of the compression bag and attached to the compression bag easily and quickly. A check valve that has been proposed to be deaerated has previously been proposed. In the check valve described in Patent Document 1, a valve element disposed in an exhaust port (first vent hole in the present invention) is provided by the elastic force of a spring. In order to urge and press the exhaust port in the direction that closes the exhaust port, when evacuating inside the compression bag, when using it on a trip that requires a cleaner and does not have a cleaner, hold the folded compression bag strongly with both hands. It compresses with a large force and increases the internal pressure of the compression bag, and this increased internal pressure has to lift the valve body against the pressing force of the spring, which is difficult to use and causes the compression bag to break And the durability will decrease. There was a title.
In addition, when using a vacuum cleaner, there is a problem that a large amount of negative pressure is required for suction, and the load on the vacuum cleaner becomes large.

そこで、特許文献２に示されるように、圧縮袋を上下から挟んで取り付けられる上下のベース部材の上ベース部材から筒状結合部を立設し、この筒状結合部内の下方の下ベース部材に開口部（本発明にいう第１通気孔）が形成され、この開口部を開閉する板状の弁体を筒状結合部内に収納し、板状の弁体をその上方から押圧する筒状押圧部を蓋体から垂下し、蓋体を回転させたときに、当該蓋体をベース部の筒状掛合部の基部外周部分に形成されたカム機構で蓋体とともに筒状押圧部を下降させ、弁体を開口部に押し付けて脱気した圧縮袋を密封するようにしたものも提案されている。   Therefore, as shown in Patent Document 2, the cylindrical coupling portion is erected from the upper base member of the upper and lower base members attached with the compression bag sandwiched from above and below, and the lower lower base member in the cylindrical coupling portion is attached to the lower base member. An opening (first vent in the present invention) is formed, a plate-like valve body that opens and closes this opening is housed in the tubular coupling portion, and a cylindrical press that presses the plate-like valve body from above When the lid is rotated from the lid and the lid is rotated, the cylindrical pressing portion is lowered together with the lid by a cam mechanism formed on the base outer peripheral portion of the cylindrical hooking portion of the base. There has also been proposed a method in which a compressed bag which has been deaerated by pressing a valve body against an opening is sealed.

ところが、こうしたものでは、蓋体を回転操作するのにともなって蓋体が昇降するために、蓋体が上昇すると、上ベース部との間に隙間が生じ、ゴミ等を咬みこみやすくなるという問題がある。
また、蓋体を上ベースに装着する部分に蓋体を回動可能にするカム機構と掛合機構とが設けられることから、構造が複雑になり高価になるだけでなく、気密性を保持することが難しく、掃除機で吸引するときに当該部分のから外気を吸引するので吸引ロスが大きくなってしまうという問題もあった。 However, in such a case, since the lid body moves up and down as the lid body is rotated, there is a problem that when the lid body rises, a gap is generated between the upper base portion and it becomes easy to bite dust and the like. There is.
In addition, a cam mechanism and a hooking mechanism that allow the lid to rotate are provided at the portion where the lid is attached to the upper base, so that not only the structure becomes complicated and expensive, but also airtightness is maintained. However, when sucking with a vacuum cleaner, since the outside air is sucked from the portion, there is a problem that suction loss increases.

本発明は上記問題点に鑑みて提案されたもので、簡単な構造で吸引ロスがない逆止弁を提供できるとともに、斯かる逆止弁を備えることにより取り扱いの容易な圧縮袋を提供できるようにすることを目的とするものである。   The present invention has been proposed in view of the above problems, and can provide a check valve having a simple structure and no suction loss, and can provide a compression bag that is easy to handle by including such a check valve. The purpose is to make it.

上記目的を達成するために本発明にかかる圧縮袋に付設する逆止弁は、圧縮して脱気可能な脱気素材を入れて封止する圧縮袋に付設する逆止弁であって、圧縮袋に穿設された装着孔に取り付けられ、中央部分に第１通気孔を有するベース部材と、ベース部材に回転可能に装着される操作部材と、操作部材の回転操作により昇降操作される昇降部材と、昇降部材に昇降移動可能に装着された弁体とを備え、昇降部材に第２通気孔を穿設し、操作部材に第３通気孔が透設され、操作部材の回転操作により昇降部材が上昇して弁体が昇降可能な隙間が生じ、袋の内圧が大気圧より高い場合にはその高い圧力により弁体が上昇して第１通気孔を開口いて圧縮袋内を第２通気孔、第３通気孔を介して外部に放出可能に連通させ、圧縮袋の内圧が大気圧以下になったときには自重ならびに気圧差により弁体が第１通気孔を閉塞するとともに、操作部材を回転操作して昇降部材を下降させると弁体が第１通気孔を密閉状に封止可能に構成したことを最も主要な特徴とするものである。   In order to achieve the above object, the check valve attached to the compression bag according to the present invention is a check valve attached to the compression bag sealed with a degassing material that can be compressed and degassed. A base member that is attached to a mounting hole formed in the bag and has a first ventilation hole in the center portion, an operation member that is rotatably mounted on the base member, and a lifting member that is lifted and lowered by a rotating operation of the operating member And a valve body attached to the elevating member so as to be movable up and down, the second elevating hole is drilled in the elevating member, the third vent hole is formed through the operating member, and the elevating member is operated by rotating the operating member. Rises to create a gap in which the valve body can be raised and lowered, and when the internal pressure of the bag is higher than atmospheric pressure, the high pressure causes the valve body to rise and open the first vent hole to open the second vent hole in the compression bag , Communicated through the third vent so as to be discharged to the outside, and the internal pressure of the compression bag is less than atmospheric pressure. The valve body closes the first vent hole due to its own weight and atmospheric pressure, and the valve body can seal the first vent hole in a sealed manner by rotating the operating member to lower the elevating member. This is the main feature.

逆止弁を設けた圧縮袋は、圧縮袋が柔軟な樹脂製のシート素材により、脱気収納素材の出し入れ口を除く周囲が閉塞された袋状に形成し、出し入れ口に、気密状に封止可能な封止手段を設けてなる圧縮袋の一部に装着孔を形成し、圧縮袋の内方から筒部が外部に突出する状態にベース部材を取り付け、当該筒部内に弁体を昇降可能に装着した昇降部材を配設し、操作部材の外筒を前記筒部に回動可能に外嵌させて請求項１に記載の逆止弁を取り付けたことを最も主要な特徴とするものである。   The compression bag provided with a check valve is formed into a bag shape that is closed around the entrance and exit of the degassing storage material with a flexible resin sheet material, and is sealed in an airtight manner at the entrance and exit. A mounting hole is formed in a part of the compression bag provided with a sealing means that can be stopped, a base member is attached in a state in which the cylinder part projects outside from the inside of the compression bag, and the valve body is moved up and down in the cylinder part The main feature is that a check valve according to claim 1 is attached by mounting an elevating member that is detachably mounted, and an outer cylinder of the operation member is rotatably fitted to the cylinder portion. It is.

本発明によれば、操作部材を回転操作して昇降部材を上昇させて弁体が遊動する隙間を形成すると、この弁体を押し上げるだけのわずかな圧力差で第１通気孔を開くことができ、差圧がなくなると、弁体の自重で下降して第１通気孔をふさいでしっかりと閉塞する。
これにより、前記した特許文献１のようにスプリングの押圧付勢力に抗して弁体を上昇させるような圧力を圧縮袋内に発生ささなくても済むことから、これを備えた圧縮袋の破損の発生を可及的に防止してその耐久性を大幅に向上させることができる利点がある。 According to the present invention, when the operating member is rotated to raise the elevating member to form a clearance in which the valve body is loosened, the first vent hole can be opened with a slight pressure difference that only pushes up the valve body. When the pressure difference disappears, the valve body descends by its own weight and closes the first vent hole and closes tightly.
As a result, it is not necessary to generate pressure in the compression bag to raise the valve body against the pressing biasing force of the spring as in Patent Document 1 described above. There is an advantage that the durability can be greatly improved by preventing the occurrence of the occurrence as much as possible.

また、逆止弁は、ベース部材、操作部材、弁体を備えた昇降部材を備えるだけの簡単な構造でありながら高い気密性を保つことができ、特許文献２のような吸引ロスもなく、安価に実施することができる利点がある。   In addition, the check valve can maintain high airtightness while having a simple structure including a base member, an operation member, and an elevating member including a valve body, and there is no suction loss as in Patent Document 2, There is an advantage that it can be implemented at low cost.

ベース部材８は、圧縮袋１の装着孔７への取り付け部１２が円板状に形成され、その上面中央部分には操作部材９を回転可能に装着する短寸の筒部１３が、合成樹脂で取り付け部１２と一体に形成されている。
この筒部１３の外周面には後述する操作部材９を回転可能に装着するための環状溝からなる枢支部１４が形成され、筒部１３の内周面には雌螺子部１５が刻設されるとともに、筒部１３の底部中央には第１通気孔１６が穿設されている（図３参照）。
円盤状の取り付け部１２の下面で上記第１通気孔１６の周囲には、当該第１通気孔１６を取り囲む状態の筒状部１７と、この筒状部１７から放射状に張り付き防止用のリブ１８が放射状に一体に突出形成してあり、筒状部１７の基端部には第１通気孔１６に連通する通気用横穴１９が形成されている。 The base member 8 has a disk-like attachment portion 12 to the attachment hole 7 of the compression bag 1, and a short cylindrical portion 13 to which the operation member 9 is rotatably attached at a central portion of the upper surface thereof. And is formed integrally with the mounting portion 12.
A pivotal support portion 14 formed of an annular groove for rotatably mounting an operation member 9 described later is formed on the outer peripheral surface of the cylindrical portion 13, and a female screw portion 15 is engraved on the inner peripheral surface of the cylindrical portion 13. In addition, a first ventilation hole 16 is formed in the center of the bottom of the cylindrical portion 13 (see FIG. 3).
A cylindrical portion 17 in a state of surrounding the first vent hole 16 around the first vent hole 16 on the lower surface of the disc-shaped attachment portion 12 and a rib 18 for preventing sticking radially from the cylindrical portion 17. Are formed so as to project radially and integrally, and at the base end portion of the cylindrical portion 17, a ventilation side hole 19 communicating with the first ventilation hole 16 is formed.

上記筒部１３に回転可能に枢支される操作部材９は、伏せ椀状に形成されており、その球面の上端部には図２に示すように第３通気孔２０が穿設されており、下面には図４に示すように第３通気孔２０の下方には放射状に配設された板状の操作片２１を突出するとともに、前記ベース部材８の筒部１３に外嵌する外筒２２が下方に垂下してある。
そして、この外筒２２の内周面には図３および図４に示すように、上記筒部の枢支部１４に嵌合する環状の突部２３が形成されている。 The operation member 9 that is pivotally supported by the cylinder portion 13 is formed in the shape of a prone ridge, and a third vent hole 20 is formed at the upper end of the spherical surface as shown in FIG. As shown in FIG. 4, a lower surface of the third vent hole 20 protrudes radially from the plate-like operation piece 21 on the lower surface and is externally fitted to the cylinder portion 13 of the base member 8. 22 hangs down.
And as shown in FIG.3 and FIG.4, the cyclic | annular protrusion 23 fitted to the pivotal support part 14 of the said cylinder part is formed in the internal peripheral surface of this outer cylinder 22. As shown in FIG.

上記昇降部材１０は、操作部材９の外筒２２がベース部材８の筒部１３に外嵌されて装着したときに筒部１３と外筒２２とで形成される弁収納室２４内に装着されるもので、有底筒状に形成され、外周面には前記ベース部材８の筒部１３の内周面に刻設された雌螺子部１５に螺合する雄螺子２５が形成されており、昇降部材１０の内周面には前記操作部材９の板状の操作片２１により当該昇降部材１０を回転操作するための板状の従動部材２６が内方に突出させてある。
そして、昇降部材１０の底部の中央には弁体１１を装着する装着孔２７が設けてあり、この装着孔２７に装着される弁体１１の外周より外側の昇降部材１０の底部には複数の第２通気孔２８が透設されている。 The elevating member 10 is mounted in a valve storage chamber 24 formed by the tube portion 13 and the outer tube 22 when the outer tube 22 of the operation member 9 is fitted and mounted on the tube portion 13 of the base member 8. Therefore, it is formed in a bottomed cylindrical shape, and a male screw 25 that is screwed into a female screw portion 15 carved on the inner peripheral surface of the cylindrical portion 13 of the base member 8 is formed on the outer peripheral surface. On the inner peripheral surface of the elevating member 10, a plate-like driven member 26 for rotating the elevating member 10 by the plate-like operating piece 21 of the operating member 9 is projected inward.
A mounting hole 27 for mounting the valve body 11 is provided in the center of the bottom of the elevating member 10, and a plurality of elevating members 10 outside the outer periphery of the valve body 11 mounted in the mounting hole 27 are provided at the bottom. A second ventilation hole 28 is provided.

上記弁体１１は、第１通気孔１６の上端部の周囲に環状に突出形成された弁座２９よりわずかに大きく形成された円板状の弁面３０部分と、この弁面３０部分の中央から上方に延出され、昇降部材１０の底部の厚さより長く形成したステム部分３１と、ステム部分３１の先端部分に抜け止め用の膨出部３２とを、弾性を有する合成樹脂エラストマで成形して形成されている。
上記ステム部分３１の直径は、昇降部材１０の底部に形成された装着孔２７よりわずかに小径に形成されており、操作部材９の回転操作により、昇降部材１０が上昇して弁座２９と昇降部材１０の底面との間が弁体の弁面３０部分の厚さより大きくなると、弁体１１がその弁面３０部分に作用する圧力により、上下に遊動可能となる。
尚、図上符号３３は操作部材に複数形成された操作用のくぼみである。 The valve body 11 includes a disc-shaped valve face 30 portion that is formed slightly larger than the valve seat 29 that is annularly formed around the upper end portion of the first vent hole 16, and the center of the valve face 30 portion. A stem portion 31 that extends upward from the bottom portion of the elevating member 10 and is formed with an elastic synthetic resin elastomer is formed on the tip portion of the stem portion 31 and a bulging portion 32 that prevents the stem portion 31 from coming off. Is formed.
The diameter of the stem portion 31 is slightly smaller than the mounting hole 27 formed at the bottom of the elevating member 10, and the elevating member 10 is raised by the rotation operation of the operating member 9 to elevate the valve seat 29. When the space between the bottom surface of the member 10 is larger than the thickness of the valve surface 30 portion of the valve body, the valve body 11 can be moved up and down by the pressure acting on the valve surface 30 portion.
Note that reference numeral 33 in the figure denotes a plurality of operating depressions formed in the operating member.

上記のように形成された逆止弁１は、図４に示すように圧縮袋１の表面１ａ側に開設された逆止弁３の装着孔７に、ベース部材８の筒部１３を圧縮袋１の内方から外方に突出させ、円盤状の取り付け部１２を気密状に接着若しくは溶着してベース部材８を固定する。
次に、装着孔２７に弁体１１を装着した昇降部材１０を回転させながら、その外周面に刻設された雄螺子２５をベース部材８の筒部１３の内周面に形成された雌螺子部１５に螺合させ、弁体１１の弁面３０が第１通気孔１６の弁座２９に当接するまで下降させる。 As shown in FIG. 4, the check valve 1 formed as described above is configured such that the cylindrical portion 13 of the base member 8 is compressed into the compression bag 1 in the mounting hole 7 of the check valve 3 opened on the surface 1 a side of the compression bag 1. The base member 8 is fixed by projecting outwardly from the inside of 1 and adhering or welding the disk-shaped attachment portion 12 in an airtight manner.
Next, the female screw 25 formed on the inner peripheral surface of the cylindrical portion 13 of the base member 8 is provided with the male screw 25 engraved on the outer peripheral surface while rotating the elevating member 10 with the valve body 11 mounted in the mounting hole 27. It is screwed into the portion 15 and lowered until the valve surface 30 of the valve body 11 comes into contact with the valve seat 29 of the first vent hole 16.

然る後、操作部材９の外筒２２を、ベース部材８の筒部１３に外嵌するように上方から圧入して外筒２２の内周面に形成されている環状の突部２３を筒部１３の枢支部１４に嵌合させると、操作部材９の板状の操作片２１と、昇降部材１０の板状の従動部材２６とが嵌合し、操作部材９の回転操作で昇降部材１０が昇降操作されるようになる。   Thereafter, the outer cylinder 22 of the operation member 9 is press-fitted from above so as to be fitted onto the cylinder portion 13 of the base member 8, and the annular protrusion 23 formed on the inner peripheral surface of the outer cylinder 22 is formed into the cylinder. When fitted to the pivotal support portion 14 of the portion 13, the plate-like operation piece 21 of the operation member 9 and the plate-like driven member 26 of the elevating member 10 are fitted, and the elevating member 10 is operated by rotating the operation member 9. Is moved up and down.

斯くして、逆止弁３が取り付けられた圧縮袋１は、図１に示すように収納口４から折り畳んだセータ等の衣服２を収納する。
そして収納口４を密封した後、圧縮袋１内を脱気する。
この圧縮袋１内を脱気にあたっては、圧縮袋１を押圧して内圧を高めるか、掃除機で吸引させる方法が用いられるのであるが、いずれにしても以下の手順で行われる。 Thus, the compression bag 1 to which the check valve 3 is attached stores clothes 2 such as a sata folded from the storage port 4 as shown in FIG.
And after sealing the storage port 4, the inside of the compression bag 1 is deaerated.
In degassing the inside of the compression bag 1, a method is used in which the compression bag 1 is pressed to increase the internal pressure or sucked with a vacuum cleaner.

先ず、図５に示すように操作部材９を回動操作して昇降部材１０を上昇させて弁体１１の弁面３０を弁座２９から離間可能な状態にする。
次に、圧縮袋１を押圧して内圧を高めるか、掃除機で吸引させて圧縮袋１の内圧を相対的に高めるかすることにより、圧縮袋１内の圧力と昇降部材１０の内方の圧力との間に圧縮袋１の内圧が高くなる差圧（気圧差）を形成する。
すると、この差圧により、弁体１１が上昇し、弁面３０が弁座２９から離れて第１通気孔１６が開かれる。
第１通気孔１６が開かれると図６に示すように圧縮袋１内の空気が、第１通気孔１６から第２通気孔２８及び第３通気孔２０を介して逆止弁１１外に流れ出て、圧縮袋１が脱気されて圧縮袋１内の容積が減少（減容）される。 First, as shown in FIG. 5, the operating member 9 is rotated to raise the elevating member 10 so that the valve surface 30 of the valve body 11 can be separated from the valve seat 29.
Next, the pressure in the compression bag 1 is increased by increasing the internal pressure by pressing the compression bag 1 or by relatively increasing the internal pressure of the compression bag 1 by suction with a vacuum cleaner. A differential pressure (atmospheric pressure difference) that increases the internal pressure of the compression bag 1 is formed between the pressure and the pressure.
Then, due to this differential pressure, the valve body 11 is raised, the valve surface 30 is separated from the valve seat 29, and the first vent hole 16 is opened.
When the first vent 16 is opened, the air in the compression bag 1 flows out of the check valve 11 from the first vent 16 through the second vent 28 and the third vent 20 as shown in FIG. Thus, the compression bag 1 is degassed and the volume in the compression bag 1 is reduced (reduced volume).

そして、押圧されていた圧縮袋１がその押圧（圧縮）から解放され、あるいは吸引していた掃除機の吸引が停止されると、圧縮袋１内の圧力が外気（大気）と等しいか、それ低下になると、弁体１１の自重もしくは差圧により弁体１１が下降し、図７に示すようにその弁面３０が弁座２９と当接して第１通気孔１６を即座に塞ぐ。
これにより、第１通気孔１６から空気が圧縮袋１内に流入するのが防止されるので、この状態で、操作部材９を回転操作して昇降部材１０を下降させ、その底部で弁体１１を第１通気孔１６の弁座２９に押圧して密閉すると圧縮袋１の圧縮状態が保持され、衣服２の脱気収納作業が終了する。 Then, when the pressed compression bag 1 is released from the press (compression), or when the suction of the vacuum cleaner that has been sucked is stopped, the pressure in the compression bag 1 is equal to the outside air (atmosphere) or When the pressure decreases, the valve body 11 descends due to its own weight or differential pressure, and the valve surface 30 comes into contact with the valve seat 29 and immediately closes the first vent hole 16 as shown in FIG.
Accordingly, air is prevented from flowing into the compression bag 1 from the first vent hole 16. In this state, the operating member 9 is rotated to lower the elevating member 10, and the valve body 11 is lowered at the bottom. Is pressed against the valve seat 29 of the first vent hole 16 and sealed, the compressed state of the compression bag 1 is maintained, and the deaeration and storage operation of the garment 2 is completed.

上述したように、弁体１１を昇降させるために操作部材９を回転操作しても昇降部材１０だけが昇降し、操作部材９は昇降することがないので、操作部材９の昇降に伴う隙間が生じるのが防止される。
これにより、隙間からゴミの咬み込みを防止することができる。 As described above, even if the operating member 9 is rotated to raise and lower the valve body 11, only the elevating member 10 moves up and down, and the operating member 9 does not move up and down. It is prevented from occurring.
Thereby, the biting of garbage from a clearance gap can be prevented.

尚、上記実施の形態では、操作部材９の板状の操作片２１ならびに昇降部材１０を回転操作するための板状の従動部材２６をそれぞれ複数設けるようにしてあるが、いずれか一方を１つにすることができるのはいうまでもないことである。
また、操作部材９の外筒２２の内周面の突部２３を、本例では図上、環状に形成するようにしてあるが、これは環状にしたものに限られず、不連続の突状や突起にすることもできる。 In the above embodiment, a plurality of plate-like operation pieces 21 of the operation member 9 and a plurality of plate-like driven members 26 for rotating the lifting member 10 are provided. It goes without saying that it can be done.
Further, in this example, the protrusion 23 on the inner peripheral surface of the outer cylinder 22 of the operation member 9 is formed in an annular shape, but this is not limited to an annular shape, but a discontinuous protruding shape. It can also be a protrusion.
