M353909 五、新型說明： 【新型所屬之技術領域】 本創作係與密封罐有關，更詳而言之是指一種密封罐 之排氣裝置。 【先前技術】 . 按，一般之密封罐係可用以將罐内空間與外界空氣加 以隔絕，因此對於保存食材或其它需隔絕空氣之物品而 言，有著一定之效果，且由於密封罐之售價不貴而經濟實 • 惠，因此頗能廣受大眾所接受。 然，有些許食材並不適宜存放於一般完全密封之空間 中，如咖啡豆或咖啡粉…等。由於咖啡豆於烘培後會自然 地散發出二氧化碳，因此若將咖啡豆或經過研磨之咖啡粉 存放於完全密封之密封罐或密封袋中時，極易使得罐體或 密封袋膨脹。尤其經過研磨之咖啡粉由於與空氣接觸之面 積較大，因此所散發出之二氧化碳濃度更高，易發生密封 罐或密封袋爆開之情事。 鲁因此，一般坊間會將經過烘焙之咖啡豆或咖啡粉以設 - 有單向排氣閥之密封袋加以密封，以藉由該單向排氣閥僅 能作單向排氣之特性，不僅使密封袋内之氣體（二氧化碳） 能透過該單向排氣閥所排出以避免袋内壓力增大，更能阻 隔密封袋外之氣體進入於密封袋内，以有效防止香味流失 及防止與氣體產生後之化學變化（變酸或變味）。 然而，由於單向排氣閥係利用高週波之方式加以連結 於密封袋上，但此種方式並無法運用於密封罐上，導致消 費者無法採用普及度更高之密封罐加以存放，而有存放此 3 M353909 種會釋放氣體食材之方式有限的缺失。 【新型内容】 有鑑於此，本創作之主要目的乃在於提供一種密封罐 之排氣裝置，係能設置於密封罐上，以使密封罐具有單向 排氣之功效者。 緣此，本創作乃提供一種密封罐之排氣裝置，包含 有：一塞體，係以軟質可受外力作用而變形之材質所製 * 成，該塞體内部形成有一容室，該塞體具有一頂面及一底 • 面，該頂面上形成有一連通至該容室之貫孔，該底面上則 形成有一連通至該容室之通孔，該塞體之外周面上環設有 一溝槽，以由該溝槽與一密封罐結合，使該通孔與密封罐 之内部空間連通；一單向排氣閥係置於該塞體之容室中， 以將由通孔進入之氣體導引至貫孔外排出，而將由貫孔進 入之氣體加以阻隔以避免由通孔進入於密封罐之内部空 間。 ^ 【實施方式】 為使貴審查委員能對本創作之特徵與特點有更進一 步之了解與認同，茲列舉以下較佳實施例並配合圖式說明 如下： 請參閱第一至第五圖，係本創作一較佳實施例所提供 一種密封罐之排氣裝置1 0 0，包含有一塞體1 0及一單 向排氣閥2 0 ;其中： 請參閱第二至第五圖，該塞體1 〇係以軟質可受外力 作用而變形之材質所製成，如矽膠、橡膠…等。該塞體1 4 M353909 0具有一第一塞件1 1及一第二塞件丄2 ;該第—塞件工 1具有一第一頂面1 1 1、一位於該第一頂面i丄丄相對 端之第一底面1 1 2及一位於該第一塞件2丄内部之容 室113,該容室113之周壁上並環繞形成有—嵌槽χ 1 6，該第一頂面1 1 1上形成有一連通至該容室丄工3 之第一通孔114,該第一底面ι12上則形成有一連通 .該容室之第二通孔1 1 5，使該第一、二通i 4、工 -1 5藉由該容室1 1 3而連通’且該第一塞件1 1之外徑 •係由該第一頂面1 1 1往第一底面1 1 2逐漸縮小；該第 一塞件12具有一第一頂面121及一位於該第二頂面 1 2 1相對端之第二底面χ 2 2，該第二頂面i 2 i上往 内形成有一預定深度之第一貫孔i 2 3，該第二底面工2 2上往内形成有一預定深度之第二貫孔丄2 4，且該第一 貝孔1 2 3係與該第一貫孔1 24連通，該第二塞件1 2 之外周面上並環繞形成有一溝槽1 2 5。 請參閱第二至第五圖，該單向排氣閥2 〇，具有一容 鲁置座2 1及-播片2 2。該容置座2 1具有-第一端面2 1 1及一第二端面2 1 2,該第一端面2 1 1上往内凹設 有一透氣室2 1 3,且該透氣室2 1 3之周壁頂緣形成有 多數位於透氣室2 1 3上方之凸擋部2 1 4，該第二端面 2 1 2上形成有多數連通至該透氣室之透孔2丄5 ;該擋 片2 2，係置於該透氣室2 1 3中，且該擒片2 2之外徑 略小於該透氣室2 1 3之内徑，使該擋片2 2可藉由外力 2用而於透氣室2 1 3之底壁至凸擋部2丄4間移動，該 谷置座2 1鄰近該第一端面2 1 ΐ之外周緣上並凸設有 一凸緣2 1 6。 5 M353909 是以，上述即為本創作一較佳實施例之主要構件介 J 紹，接著再將組裝方式及使用特點介紹如下： 首先，睛參閱第二至第五圖，當本創作密封罐之排氣 裝置1 0 0欲裝設於-密封罐9 〇上之前，先將該單向排 氣閥2 0置於該第-塞件丄工之容室丄工3中，並由該單 向排氣閥2 0之凸緣2 1 6嵌入於該第一塞件1 1之嵌 ，槽1 1 6中，以將該單向排氣閥2 〇固定於該容室丄丄 -内，再將該第-塞件i i之第一頂面工工工與該第二塞件 _ 1 2之第二底面1 2 2貼接黏著結合，使該第一塞件工工 與該第二塞件1 2結合為一體。 接著，將該第一塞件丄i之第一底面丄丄2穿入於一 密封罐9 0之封蓋9 1開口 9 2中，使由該封蓋9 χ之開 口 9 2周緣嵌卡於該第二塞件i 2外周面之溝槽丄2 5 中，使該排氣裝置1 〇 〇與該密封罐9 〇之封蓋9丄結合 ，一體’且該第一塞件丄i之第一底面i i 2係位於^ 蓋9 1之内側面上，而該第二塞件丄2之第二頂面丄2工 •係位於該封蓋9 1之外側面上，如此，便完成本創作排氣 袭置1 〇 0與密封罐9 0之封蓋9 1結合。 藉由本創作密封罐之排氣裝置i 〇 〇，便可使密封罐 9 0亦能具備單向排氣之功能，當密封罐g 〇内之食材散 發出氣體時，其氣體便能將該擋片2 2往上推移至與該凸 擋部2 1 4接觸，使密封罐9 0内之氣體能依序經由=第 二通孔1 1 5、透孔2 1 5、透氣室2 1 3、第一通孔工 1 4、第二貫孔1 24、第一貫孔1 2 3而排出於密封罐 9 0外，使密封罐9 〇内之壓力得以維持穩定。由於該單 向排氣閥2 0僅供氣體以單一方向流經，因此當密封罐9 6 M353909 〇外部之氣體由第二塞件丄2之第一貫孔丄2 3、 # 孔1 2 4進入至透氣室2 1 3中時，會將該擋片疾 =透氣室2 1 3之底壁上而將透孔2 χ 5封閉，進而使 外4氣體無法進入於該密封罐9 〇内部。 此，本創作密封罐之排氣裝置i 〇 〇，利用塞體1 〇與單向排氣閥2 Q之結合’而可便利地結合於密封罐9 .〇上，以使密封罐亦能具有單向排氣之功效。 - 另外，雖然上述實施例該塞體係由一第一塞件與一第 •二塞件所結合而成，但實際上該塞體亦能採用一體^造之 方式加以製成，其同樣能達到本創作之目的。 以上所揭，僅為本創作之較佳實施方式而已，並非用 =限定本創作實施例的範圍，本技術領域内的一般技術人 員根據本創作所作的均等變化，以及本領域内技術人員熟 知的改變，仍應屬本創作涵蓋的範圍。 【圖式簡單說明】 ，一圖係本創作一較佳實施例之使用狀態立體圖。 瞻第一圖係本創作一較佳實施例之立體分解圖。 ，二圖係本創作一較佳實施例之使用狀態剖視圖。 第四圖係本創作一較佳實施例之立體分解圖。 第五圖係本創作一較佳實施例之使用狀態剖視圖。 【主要元件符號說明】 密封罐之排氣裝置1 〇 〇 10 第一塞件11 第一頂面11丄 第一底面112 7 M353909 容室1 1 3 第一 通孔 1 1 4 第二通孔 1 1 5 嵌槽 11 6 第二塞件 1 2 第二 頂面 1 2 1 第二底面 1 2 2 第一 貫孔 1 2 3 第二貫孔 1 2 4 溝槽 12 5 單向排氣 閥 2 0 容置座2 1 第一 端面 2 1 1 弟—端面 2 1 2 透氣 室2 1 3 凸擋部2 1 4 透孔 2 1 5 凸緣2 1 6 擋片 2 2 密封罐9 0 封蓋9 1 開口 9 2M353909 V. New description: [New technical field] This creation is related to sealed cans, and more specifically refers to an exhaust device for sealed cans. [Prior Art] . Generally, the sealed can is used to isolate the space inside the can from the outside air, so it has a certain effect on the preservation of the food or other items that need to be insulated, and because of the price of the sealed can. It is not expensive and economically beneficial, so it is widely accepted by the public. However, some ingredients are not suitable for storage in a generally sealed space, such as coffee beans or coffee powder...etc. Since the coffee beans naturally emit carbon dioxide after baking, if the coffee beans or ground coffee powder are stored in a completely sealed sealed can or sealed bag, the can or the sealed bag is easily expanded. In particular, the ground coffee powder has a higher concentration of carbon dioxide due to contact with air, and is more likely to cause a sealed can or a sealed bag to burst. Therefore, in general, roasted coffee beans or coffee powder will be sealed with a sealed bag with a one-way exhaust valve, so that the one-way exhaust valve can only be used for one-way exhaust. The gas (carbon dioxide) in the sealed bag can be discharged through the one-way exhaust valve to prevent the pressure inside the bag from increasing, and the gas outside the sealed bag can be prevented from entering the sealed bag, thereby effectively preventing the loss of the fragrance and preventing the gas from being trapped. Chemical change (acid or odor) after production. However, since the one-way exhaust valve is connected to the sealed bag by means of high frequency, this method cannot be applied to the sealed can, and the consumer cannot use the more popular sealed can to store it. There are limited ways to store this 3 M353909 species that will release gaseous ingredients.
