Description

【0001】
【発明の属する技術分野】
本発明は真空保管袋の空気排出口に関し、より詳しくは空気の排出と遮断を調節する弁体の取り付け構造を改善し、弁体の耐久性と密閉性能を向上させた空気排出口に関する。
【0002】
【従来の技術】
一般に寝具類、衣類等は保管時に大きい収納空間を占ながら、湿気によって黴が発生し、虫がつくなど保管上の問題点がある。
【0003】
このような寝具類及び衣類等を安全且つ効率的に保管するためのものが真空保管袋である。真空保管袋は開閉可能な入口部を備え、所定位置に空気を排出するための空気排出口を備え、寝具類や衣類等を前記真空保管袋の入口部を開封して収納したあと入口を閉じ、前記空気排出口に真空掃除機を連結して真空掃除機の吸引力で真空保管袋内部の空気を外に排出させ、寝具類や衣類の嵩を減少させるものである。
【0004】
図5及び図6は、それぞれ従来の真空保管袋の空気排出口を示す斜視図と断面図である。
【0005】
図示されているように、胴体10に固定板12を備えて前記固定板12が真空保管袋の所定位置に密着・固定できるようにし、前記胴体10の中心には空気通路15を備えており、このような空気通路15の開閉のため弁体20が前記胴体に形成された空気通路15の一側に結合されている。このような弁体20は、弾性的に変形して開閉する開閉片22と、前記開閉片22を固定するため前記開閉片の底面に引き出されて形成された固定軸24と、前記開閉片22の両端と連結して開閉片22を支える外側板26で構成されている。
【0006】
このような従来の空気排出口の動作を検討すると、図2に点線で示されているように弁体に真空掃除機の吸入口30を密着して動作させると、真空掃除機の吸引力により開閉片22が外側板26と連結された部分を中心に上方に曲げられて空気通路15が開放され、真空保管袋内部の空気が真空掃除機を経て外部に排出される。空気を全て除去し真空掃除機の吸入口30を空気排出口から分離すると、前記開閉片22は自らの弾性力により原状復帰することになり、このようになると開閉片22の下側の真空保管袋内部の気圧より、開閉片22上方の気圧が一層高いので開閉片22が空気通路15を密着して閉鎖し、これ以上空気が疎通できなくなり内部は真空状態を維持することになる。
【0007】
ところが、このような従来の空気排出口の場合開閉片が円板型に形成されており、その両端と中心だけが支持を受けるようになっているため、たとえ弾性材質で作成されているとしても真空掃除機からの吸引による開閉片の曲げだけでは、弁体の開口部の開き具合はわずかであり、これに伴い弾性力も微弱であるので真空掃除機の吸入口を除去した後も、空気通路を速やかに閉鎖できないという欠点があった。
【0008】
また、従来の別の真空保管袋の空気排出口の例として、図7,8に示したものが挙げられる。この空気排出口は、布団、毛布、厚手の衣類などの収納物を圧縮収納して保存する袋体を備えた圧縮保存袋の弁構造であって、袋体の外に延びるように配設される偏平管状の吸引通路33と、袋体31の端部から袋体31の中に延びるように配設され、吸引通路33と連通する偏平管状の弁本体32と、吸引通路33の内周面に配設され、袋体31と外気との通気を遮断するために吸引通路33を封鎖する封鎖ファスナー34とを含むものである。そしてこの空気排出口は、圧縮保存袋内が減圧され、ほぼ真空状態となる時、圧縮袋31内部の気圧差により弁本体32の外側が押圧され、弁本体32の内側面どうしが密着される。そして、封鎖ファスナー34で弁の吸引通路33内を封鎖することにより、袋体内と外気との通気が遮断される。
【0009】
しかしながら、ファスナー34自体は吸引通路33の端にあるので、保管時に他の保管物あるいは使用者との接触が多くなることを免れない。そのため、ファスナー34が緩みやすくなる。その結果、そこから空気漏れが生じやすく、吸引通路33の弁本体32の密閉性が低下し、圧縮袋31内に空気が入る。つまり、保管場所での出し入れが多い場合などはその密閉性を維持しにくいという欠点があった。

【0011】
【発明が解決しようとする課題】
したがって、本発明の目的は開閉片が全体的に連結されているため耐久性に優れ、さらに、密閉力を向上させた真空保管袋の空気排出口を提供することにある。
【0012】
【課題を解決するための手段】
本発明に係る空気排出口は、空気の吸引通路を形成しており真空保管袋に取り付けられる胴体と、前記胴体の空気通路を開閉する弁体でなる真空保管袋の空気排出口であり、前記胴体は真空保管袋ヘの取付けが容易であるよう固定板を形成した第1胴体と、前記弁体を固定するための固定端を備える第2胴体との結合でなり、前記第1胴体の底面には空気排出口が吸着により閉鎖されることを防ぐための複数の翼部を備え、前記空気通路の中心に前記翼部と一体に半球形突出部を備え、前記弁体には前記半球形突出部に対応する通孔を形成し、空気排出口の開閉が前記半球形突出部を中心にその周囲で行われるようにしたものである。
【0013】
前記弁体は、前記第2胴体の固定端が挿入される固定溝を形成し、真空掃除機の吸入口と接触する上部は弾性材質でなり、前記真空掃除機の吸入口と密着できるようにするのが好ましい。
【0014】
【発明の実施の形態】
以下、本発明の好ましい実施の形態を図面等に基づき詳しく説明する。
図3は、本発明に係る真空保管袋の空気排出口の斜視図である。図4は、本発明に係る真空保管袋の底面図である。
【0015】
図示されているように、本発明に係る真空保管袋の空気排出口は空気通路を形成している胴体100と、前記胴体に形成された空気通路を開閉するよう弾性材質でなる弁体200とで構成され、前記胴体100はその周囲に所定面積を有する円板型の固定板112を備え、前記固定板112を保管袋の所定部位に密着して空気排出口を固定するようにする。
【0016】
本発明の空気排出口の空気通路の中心には半球形突出部116を備え、前記空気通路がドーナツ形をかたどることになり、これに伴い空気通路を開閉するための弁体200の開閉片206も前記半球形突出部116に対応する通孔を形成している。このような開閉片の動作は、図5a〜図5bを参照して後述する。
【0017】
図4は、本発明に係る空気排出口の底面を示しているが、底面には前述した空気通路が真空保管袋内部に保管された内容物により詰まるのを防ぐため、下方に形成されている翼部114を備えている。前記翼部114は、空気排出口の中心から放射状に形成されており、その中心部分が半球形突出部116と一体に形成されている。
【0018】
図5aは、翼部を通過しないA−A線に沿った断面図である。図5bは、翼部を通過するB−B線に沿った断面図である。
【0019】
空気排出口の胴体100は、真空保管袋に取り付けられる固定板112と、空気通路208の閉鎖を防ぐ放射線状の翼部114、及びこれと一体に形成された半球形突出部116を備える第1胴体110と、弁体200と結合するための固定端122を形成している第2胴体120との結合で構成されている。
【0020】
弾性材質で作成される弁体200は円筒状の胴体201と、前記胴体201の内側に引き出されて形成され中央には半球形突出部116に対応する通孔を備えている開閉片206、前記胴体201の上面と下面にそれぞれ外側に引き出されて形成された上板202と下板204で構成される。このような弁体200の固定は、胴体201の外周面で形成されている前記上板202と下板204の中間部分に形成される固定溝203に、第2胴体120の固定端122が挿入されるようにすることにより行われる。
【0021】
点線で示した図5aの図面符号206aは、開閉片206が開放された状態を示している。図示されているように、開閉片206の開放は真空掃除機の吸入口300側に開閉片206の通孔部位が吸い上げられることにより行われることになるが、このような開放の形態により通孔周囲の開閉片部材等が全て変形することになり、これにより開閉片の一部のみ変形を経ることになる従来の方式に比べ優れた復元力を持つことになる。さらに、本発明は開閉片206の開放が空気通路208の中心部分で行われるようにすることにより、真空掃除機の吸入口300近くの外周面が開放される従来の方式より吸引時の空気抵抗も減少することになる。
【0022】
【発明の効果】
前述のように、本発明に係る真空保管袋の空気排出口は弁体が中央の通孔を形成しており、前記通孔が拡大されながら上部に湾曲すると共に弁体の開放が行われることになるので、開放時に前記通孔の周辺部は通孔拡大による変形と上部に湾曲する変形を全て受けることになるので強力な復元力を有することになり、真空掃除機の吸入口が除去されると速やかに原形に復元され密閉力も向上するという効果がある。
【0023】
さらに、空気の吸引が弁体の外周面でない中心の半球形突出部を中心に行われることになるので、吸引時の空気抵抗が減少されて吸引作業の効率を向上させるという効果も得る。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air outlet of a vacuum storage bag, and more particularly, to an air outlet having an improved valve body mounting structure for controlling air discharge and shutoff, and having improved durability and sealing performance of the valve body.
[0002]
[Prior art]
In general, bedding and clothes occupy a large storage space during storage, and have a storage problem such as generation of mold due to moisture and insects.
[0003]
A vacuum storage bag stores such beddings, clothes, and the like safely and efficiently. The vacuum storage bag is provided with an openable and closable inlet portion, and is provided with an air outlet for discharging air to a predetermined position, and after closing the inlet portion of the vacuum storage bag for storing beddings, clothes, etc., the inlet is closed. In addition, a vacuum cleaner is connected to the air outlet, and the air inside the vacuum storage bag is discharged to the outside by the suction force of the vacuum cleaner, thereby reducing the bulk of bedding and clothes.
[0004]
5 and 6 are a perspective view and a sectional view, respectively, showing an air outlet of a conventional vacuum storage bag.
[0005]
As shown, a fixing plate 12 is provided on the body 10 so that the fixing plate 12 can be in close contact with and fixed to a predetermined position of the vacuum storage bag, and an air passage 15 is provided at the center of the body 10. A valve body 20 is connected to one side of the air passage 15 formed in the body for opening and closing the air passage 15. The valve body 20 includes an opening / closing piece 22 that elastically deforms to open and close, a fixed shaft 24 formed by being pulled out from the bottom surface of the opening / closing piece to fix the opening / closing piece 22, And an outer plate 26 that supports the opening / closing piece 22 in connection with both ends of the outer plate.
[0006]
Considering the operation of such a conventional air outlet, when the suction port 30 of the vacuum cleaner is operated in close contact with the valve body as shown by a dotted line in FIG. The opening / closing piece 22 is bent upward around the portion connected to the outer plate 26 to open the air passage 15, and the air inside the vacuum storage bag is discharged to the outside through the vacuum cleaner. When all the air is removed and the suction port 30 of the vacuum cleaner is separated from the air discharge port, the opening / closing piece 22 returns to its original state by its own elastic force. Since the air pressure above the opening / closing piece 22 is higher than the air pressure inside the bag, the opening / closing piece 22 closes and closes the air passage 15, so that air cannot be communicated any more and the inside is maintained in a vacuum state.
[0007]
However, in the case of such a conventional air outlet, the opening / closing piece is formed in a disk shape, and only both ends and the center are supported, so even if it is made of an elastic material. If only the opening and closing pieces are bent by suction from the vacuum cleaner, the degree of opening of the opening of the valve body is slight, and the elastic force is also weak.Therefore, even after removing the suction port of the vacuum cleaner, the air passage is removed. There was a drawback that it was not possible to quickly close.
[0008]
FIGS. 7 and 8 show examples of the air outlet of another conventional vacuum storage bag. This air discharge port is a valve structure of a compression storage bag provided with a bag body for compressively storing and storing items such as futons, blankets, and thick clothing, and is provided so as to extend outside the bag body. A flat tubular suction passage 33, a flat tubular valve body 32 arranged to extend from the end of the bag body 31 into the bag body 31 and communicating with the suction passage 33, and an inner peripheral surface of the suction passage 33. And a closing fastener 34 for closing the suction passage 33 in order to shut off the ventilation between the bag body 31 and the outside air. When the inside of the compression storage bag is decompressed and becomes almost vacuum, the outside of the valve body 32 is pressed by the pressure difference inside the compression bag 31 and the inner surfaces of the valve body 32 are brought into close contact with each other. . By closing the inside of the suction passage 33 of the valve with the closing fastener 34, the ventilation between the bag body and the outside air is blocked.
[0009]
However, since the fastener 34 itself is located at the end of the suction passage 33, it is unavoidable that contact with other stored items or the user during storage is increased. Therefore, the fastener 34 is easily loosened. As a result, air leakage easily occurs therefrom, and the sealing property of the valve body 32 in the suction passage 33 is reduced, so that air enters the compression bag 31. In other words, there is a drawback that it is difficult to maintain the hermeticity when the storage place is frequently taken in and out.

[0013]
The valve body has a fixing groove into which the fixed end of the second body is inserted, and an upper portion which is in contact with a suction port of the vacuum cleaner is made of an elastic material so that it can be in close contact with the suction port of the vacuum cleaner. Is preferred.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings and the like.
FIG. 3 is a perspective view of an air outlet of the vacuum storage bag according to the present invention. FIG. 4 is a bottom view of the vacuum storage bag according to the present invention.
[0015]
As shown, the air outlet of the vacuum storage bag according to the present invention has a body 100 forming an air passage, and a valve body 200 made of an elastic material to open and close the air passage formed in the body. The body 100 is provided with a disk-shaped fixing plate 112 having a predetermined area around the body 100. The fixing plate 112 is closely attached to a predetermined portion of the storage bag to fix the air outlet.
[0016]
A hemispherical projection 116 is provided at the center of the air passage of the air discharge port of the present invention, and the air passage has a donut shape, whereby the opening / closing piece 206 of the valve body 200 for opening and closing the air passage is provided. Also, a through hole corresponding to the hemispherical projection 116 is formed. The operation of such an opening / closing piece will be described later with reference to FIGS. 5A to 5B.
[0017]
FIG. 4 shows the bottom surface of the air discharge port according to the present invention, and the bottom surface is formed with the above-described air passage in order to prevent clogging with the contents stored inside the vacuum storage bag. The wing 114 is provided. The wing 114 is formed radially from the center of the air outlet, and the center portion is formed integrally with the hemispherical projection 116.
[0018]
FIG. 5a is a sectional view taken along line AA which does not pass through the wing. FIG. 5b is a cross-sectional view along the line BB passing through the wing.
[0019]
The body 100 of the air outlet is provided with a fixing plate 112 attached to the vacuum storage bag, a radial wing 114 for preventing the air passage 208 from being closed, and a first half provided with a hemispherical projection 116 formed integrally therewith. It comprises a body 110 and a second body 120 forming a fixed end 122 for connection with the valve body 200.
[0020]
The valve body 200 made of an elastic material has a cylindrical body 201 and an opening / closing piece 206 which is formed by being pulled out inside the body 201 and has a through hole in the center corresponding to the hemispherical projection 116. An upper plate 202 and a lower plate 204 are formed on the upper and lower surfaces of the body 201 by being pulled out to the outside, respectively. The fixing of the valve body 200 is performed by inserting the fixed end 122 of the second body 120 into a fixing groove 203 formed in an intermediate portion between the upper plate 202 and the lower plate 204 formed on the outer peripheral surface of the body 201. This is done by doing so.
[0021]
Reference numeral 206a of FIG. 5A indicated by a dotted line indicates a state where the opening / closing piece 206 is opened. As shown in the figure, the opening of the opening / closing piece 206 is performed by sucking up the through-hole portion of the opening / closing piece 206 toward the suction port 300 side of the vacuum cleaner. All of the surrounding opening / closing piece members and the like are deformed, thereby having a superior restoring force as compared with the conventional method in which only a part of the opening / closing piece undergoes deformation. In addition, the present invention allows the opening and closing piece 206 to be opened at the center of the air passage 208, so that the outer peripheral surface near the suction port 300 of the vacuum cleaner is opened. Will also decrease.
[0022]
【The invention's effect】
As described above, the air outlet of the vacuum storage bag according to the present invention has the valve body forming a central through-hole, and the through-hole is bent upward while being enlarged, and the valve body is opened. Therefore, at the time of opening, the peripheral portion of the through hole receives both the deformation due to the expansion of the through hole and the deformation curving upward, so that it has a strong restoring force, and the suction port of the vacuum cleaner is removed. This has the effect of quickly restoring the original shape and improving the sealing force.
[0023]
Further, since the air is sucked around the center hemispherical projection which is not the outer peripheral surface of the valve body, the air resistance at the time of suction is reduced and the effect of improving the efficiency of the suction operation is obtained.
