Description

可抽真空之密封容器 Vacuum sealable container

技术领域本发明系与密封容器有关，更详而言之，尤指一种结构简单，能应用于各种形状与材质密封容器之可抽真空结构设计。背景技术习知各种形状之密封容器结构，如「第 1 图」所示（以圆形开口容器为例），主要是包括一开口之容器 10与一盖体 20, 该盖体 20 系设置于该容器 10开口处之顶边 11。该盖体 20与该容器 10开口处之顶边 11接触面设有 —环状之凹槽 23, 且一密封垫 24设置于该凹槽 23 内，使得该容器 10之顶边 11可套入该凹槽 23与该密封垫 24接合。另外，在邻近该顶边 11 外侧设有复数个凸出之固定部 12, 而该盖体 20设有相对应之紧扣翼 21, 该些紧扣翼 21 系铰接于盖体 20外围，该些紧扣翼 21 可转动，且该些紧扣翼 21上各设有一穿孔 22与该些固定部 12相对应。当盖体 20置于容器 10之开口处时，用手指压下紧扣翼 21, 将紧扣翼 21压向容器 10之固定部 12后，该些固定凸部 12将分别穿越该些穿孔 22 而紧扣，使该盖体 20 紧盖于该容器 10之开口，藉由该容器 10之顶边 11 紧压该密封垫 24于该凹槽 23 内，使该容器 10 内部空间与外界隔绝形成密封的状态。但是，该些紧扣翼 21 的设计容易因为重复紧扣及打开的动作，而使铰接处撕裂或断裂，如果增加此处的厚度，虽然可以较不易撕裂或断裂，但铰接处如果太厚，该些紧扣翼 21 的紧扣及打开动作将会变的很吃力，不易单手操作。另外，该些固定部 12的设计也将无法保有该容器 10开口的完整性，且开口为圆形时该盖体 20之紧扣翼 21 的穿孔 22必须与该些固定凸部 12对准，才可以使紧扣翼 21 紧扣于固定部 12, 操作上相当不便。另一种密封容器之结构，如 r第 2图」所示，以圆形开口容器为例，该结构也是应用在一容器 30与一盖体 40，该容器 30开口处具有平滑之顶边 31, 该盖体 40设置于该顶边 31 上方。其中该盖体 40 下方设有一凸出之凸环部 43,使盖体 40下表面及该凸环部 43外侧形成一环状之顶接部 41, 且该顶接部 41某一处可延伸扩大形成一扳部 42。其中该凸环部 43外径略小于该容器 30之开口，且该凸环部 ⁴³外侧壁设有一环绕之凹槽 44 , 一片状式密封圈 45部分外露的插设于该四槽 44 , 且该密封圏 45上某一处中央设有一透气孔 46。当该盖体 40盖置于该容器 30之顶边 3 1 时，该凸环部 43被塞入该顶边 3 1 内侧，且藉由该透气孔 46排出该容器 30 内部之空气使该凸环部 43 可被挤压塞入，直到该顶接部 41与顶边 3 1相抵，且外露之密封圈 45将挤压于该凸环部 43与该容器 30 内壁之间，该密封圈 45的紧迫挤压将使该容器 30 内部之空间将与外界隔绝形成密封的状态。而藉由该外凸之扳部 42 , 使用者可轻易向上的扳动该盖体 40脱离该容器 30开口处。片状式的密封圈 45 虽然使容器开口保留原状，但用以排气之穿透孔BACKGROUND OF THE INVENTION 1.

DETAILED DESCRIPTION OF THE INVENTION The detailed description and the technical description of the present invention will be further described by the embodiments, but it should be understood that these embodiments are for illustrative purposes only and should not be construed as The limit. Please refer to the "Fig. 3 to Fig. 4", which is a schematic perspective view of the sealed container of the present invention. The present invention is a sealed container for a container 200 having an opening 220 and a cover 100, wherein the cover 100 includes: a convex ring portion 130 disposed under the cover 100, the convex ring portion 130 The sleeve 220 is inserted into the opening 220 of the container 200, and an annular top portion 110 is formed on the outer side of the convex portion 130. The top portion 110 is further extendable to form a trigger portion 120. 120. The user can easily pull the cover 100 away from the opening 220 of the container 200. A first groove 141 is disposed around the outer side wall of the convex ring portion 130, and the first groove 141 is connected to the top portion 110. A second groove 142 is disposed around the outer side wall of the convex ring portion 130, and the second groove 142 is disposed around the outer side wall of the convex ring portion 130. The second groove 142 is adjacent to the top of the convex ring portion 130; and a first sealing ring 151 of a shape, the first sealing ring 151 is inserted into the first groove 141 and partially exposed to the top portion 110 a second sealing ring 152 in the form of a piece, the second sealing ring 152 is inserted into the second groove 142 and partially exposed. The outer diameter of the convex ring portion 130 is slightly smaller than the opening 220 of the container 200. After the convex ring portion 130 is inserted into the opening 220, the exposed second sealing ring 152 is pressed against the convex ring portion 130 and the container 200. Between the inner walls, and the first sealing ring 151 is pressed between the abutting portion 110 and the top edge of the container 200, the inner space of the container 200 is insulated from the outside to form a sealed state. A cover hole 102 is disposed on the surface of the cover body 100. The sleeve hole 102 is provided with at least one air hole 103, and a ventilation umbrella valve 160 is disposed in the sleeve hole 102 for controlling the air between the outside and the inside of the container 200. In and out. The gas permeable umbrella valve 160 includes a diaphragm 161 having a width covering the air vent 103 and abutting against the surface of the cover 100. The air venting valve 160 also includes a pressing portion 162 located above the diaphragm 161, and a damper portion 163 located under the diaphragm 161 for inserting the venting umbrella valve 160 into the sleeve hole 102. The breathable umbrella valve 160 can be forcibly pressed into the sleeve hole 163, and is positioned by the card portion 163 against the bottom wall of the cover body 100. Moreover, a flange 164 is recessed downwardly from the intersection of the pressing portion 162 and the diaphragm 161, so that the diaphragm 161 can be easily bent upward and further separated from the air hole 103. As shown in the cross-sectional view of Fig. 5, when the cover 100 is to cover the opening 220 of the container 200, when a portion of the convex ring portion 130 is inserted into the opening 220, the exposed second The seal ring 152 will be pressed between the collar portion 130 and the inner wall of the container 200. At this time, the cover 100 is not easily covered due to the imbalance of pressure inside and outside the container 200. Therefore, the present invention, by the deflation function of the gas permeable umbrella valve 160, presses the pressing portion 162 of the gas permeable umbrella valve 160 to lift the diaphragm 161 upward, and transmits the pressure inside and outside the container 200 through the air hole 103, so that the pressure inside and outside the container 200 is balanced. The collar portion 130 and the second sealing jaw 152 can continue to be inserted into the opening 220 until the first sealing ring 151 on the surface of the abutting portion 110 interferes with the top edge 210 of the container 200. In this manner, when the user does not press the pressing portion 162, the cover 100 separates the internal space of the container 200 from the outside by the first sealing ring 151 and the second sealing ring 152 formed of an elastic material to form a sealed state. . In the sectional view of the vacuuming, as shown in the sectional view of FIG. 6 , a recess 101 is recessed downwardly from the upper surface of the cover 100, and the sleeve 102 is disposed in the recess 101 for manual operation. The air extracting device 300 is positioned to draw air on the recess 101. When vacuuming, for example, the manual suction device 300 can be used to draw air on the recessed port 101, at which time the diaphragm 161 is sucked up and lifted up, and the air inside the container 200 can be extracted by the air holes 103. When the inside of the container 200 is under vacuum, the air extracting device 300 is unplugged, and the diaphragm 161 on the gas permeable umbrella valve 160 is pressed against the air holes 103 by the pressure, and the inside of the container 200 is kept vacuum. The articles contained in the container 200 can extend the shelf life of the articles. In addition, after the pumping is performed, the second sealing ring 152 may be deflated due to deformation between the convex ring portion 130 and the inner wall of the container 200. Therefore, the first sealing ring 151 is disposed on the topping. Between the portion 110 and the top edge 210, the first sealing ring 151 will be more tightly pressed by the abutting portion 110 and the top edge 210 after being extracted, so that the convex ring portion 130 and the inner wall of the container 200 are separated. The precision of the thickness of the second seal ring 152 can be neglected without the situation that the second seal ring 152 will be deflated after the vacuum is applied, thereby increasing the convenience in manufacturing. As shown in Fig. 7, it is a sectional view of the combination when the present invention is released. If the cover 100 is to be opened, the pressing portion 162 of the gas-permeable umbrella valve 160 is pressed, and the diaphragm 161 is deformed by the pressing of the pressing portion 162, so that the air hole 103 on the surface of the recess 101 can be separated. The outside air is smoothly introduced into the container 200, so that the cover 100 can be easily opened. In addition, in the application, when the vacuum sealing cover of the present invention is used for both large and small containers, the air in the large container can be directly sucked, so that the small container housed in the large container is also affected. The pressure changes, the internal air can be released into a large container, and then the inside of the large container can be evacuated, so that the containers of the inner and outer devices can reach a vacuum state. The vacuum sealing cover of the invention penetrates the application of the sheet-shaped sealing ring, so that there is no need to have a fixing protrusion outside the container, and the shape of the opening is no longer restricted, and the operation is more convenient when the alignment problem is not used. Moreover, through the venting function of the gas permeable umbrella valve, there is no need to provide a penetration hole on the sealing ring, so the container has a good sealing function. At the same time, through the gas-filled umbrella valve, the vacuum sealing cover of the present invention can extract the air in the container through the air suction device to form a vacuum, and maintain the vacuum inside the container, so that the articles contained in the container can be extended. Its shelf life. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
