The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
A kind of keying vent plug of the keying vent plug 2 in the seal cover cap 1 and cutaway view that seal cover cap cooperates assembling of embedding as depicted in figs. 1 and 2; With reference to figure 2 with like Fig. 3, described keying vent plug 2 comprises: vent plug cylinder 21 and vent plug skirt body 22; Said vent plug cylinder 21 has the upper end sealing; The hollow structure of lower ending opening; Be made up of with tapered portion 212 shoulder portion 211, wherein, said shoulder portion 211 is located at vent plug cylinder 21 bottoms; Shoulder portion 211 is against the lower end of seal cover cap through hole 11, and tapered portion 212 is increased to upper section by shoulder portion 211 gradually; Said vent plug skirt body 22 is progressively to extend outwardly into certain altitude again to extending below formed umbrella-shaped structure by the tapered portion on the vent plug cylinder 21 212, and this vent plug colony 22 is sized to the upper end opened portion 111 that covers and cover seal cover cap through hole 11 basically; Described vent plug skirt body 22 is provided with at least one pore 222; This pore 222 can play different effects in the different phase of using this keying vent plug, and when bleeding, this pore 222 makes vacuum pump and container be communicated with; Can conveniently extract the gas in the container out, reach the purpose of vacuum; When not bleeding, there is a pressure difference in container with extraneous, thereby produces a downward pulling force; Open and close vent plug and container and keep vacuum state; At this moment, this vent plug skirt body 22 forms the chamber that is communicated with seal cover cap 1, is consistent through this pore 221 and extraneous pressure; In the time of need opening seal cover cap, rock the vent plug cylinder gently and get final product.
As shown in Figure 2, shoulder portion 211 is annular arrangement, and its diameter is greater than the internal diameter of seal cover cap through hole 11, less than the external diameter of seal cover cap through hole 11; The lower end of seal cover cap through hole 11 is provided with air extractor vent 112.
Like Fig. 3 and shown in Figure 4; Vent plug cylinder 21 upper ends are tapered, and it highly is higher than the height of vent plug skirt body 22, this structure; When needs are opened seal cover cap; As long as the upper end of rocking vent plug cylinder 21 gently makes the circular conical surface of vent plug cylinder upper conical portion and the face of cylinder of seal cover cap through hole not to fit like a glove, can open seal cover cap easily.
Like Fig. 4 and shown in Figure 5, described pore 221 is arranged on the inboard of vent plug skirt body 22; Vent plug skirt body 22 peripheries are provided with an annular flange flange 222, and this structure has played supporting role.
Preferably, described vent plug cylinder 21 and the 22 one machine-shapings of vent plug skirt body.
Preferably, described vent plug cylinder 21 is processed with vent plug skirt body 22 usefulness elastomeric materials.
The utility model opens and closes vent plug and seal cover cap and closely cooperates under state of nature, and the inside and outside pressure of seal box is through pore, and air extractor vent reaches the slit balance that opens and closes between vent plug and the seal cover cap.
During use, extract air in the container out with vacuum pump, vacuum pump places and opens and closes on the vent plug; Vent plug skirt body supports vent plug cylinder and vacuum pump; Simultaneously, closely be attached on the seal cover cap, make vacuum pump pass through the confined space of pore and a gap that opens and closes vent plug and seal cover cap and a perforation of container formation; During extracting air, the gas in the container outwards flows, and simultaneously, an outside thrust is arranged, and gas can be from the aerial vacuum pump that flows into of gap and its; When stopping extracting air; The barometric pressure of outside is higher than the barometric pressure of receptacle, opens and closes vent plug and receives downward pulling force immediately, owing to receive downward pulling force; The circular conical surface of the tapered portion on the vent plug cylinder upper end that is against the seal cover cap through hole tightly; Thereby stoped ambient atmosphere to get in the container, and pressure reduction is big more, sealing effectiveness is good more; Can keep vacuum state for a long time in the container like this;
When opening seal cover cap; Only need shake vent plug cylinder upper end gently; Make the circular conical surface of vent plug cylinder upper conical portion and the face of cylinder of seal cover cap through hole not to fit like a glove, in the air admission container outside making, when the inner and outer air pressure difference is identical like this; Just can easily closed cover and container be separated, can take out the food in the container.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
