Abstract

The utility model relates to a vacuum sealing device of a container, which comprises an air plug and an air suction pump matched with the air plug. The vacuum sealing device is characterized in that the air plug is made of soft materials, the lower part of the air plug is provided with an air hole, a sealing ring is arranged on the outer circumference of the air plug, and the upper part of the air plug is provided with a circular ring-shaped air suction interface which is provided with a convex block. An air gap is arranged on the convex block and is communicated with the air hole, the lower end of the air suction interface is provided with a flange and a reverse trapezoid shape is formed between the flange and the sealing ring which is adjacent to the flange. The air plug which is used as a bottle (or a jar) plug is directly plugged into a bottle opening (or an air mouth of a jar cover), and the air in a jar body or a bottle body can be sucked by the air suction pump to form vacuum. The utility model has the advantages of simple structure and good sealing effect, and is suitable for the freshness preservation of food and soft drinks.

Description

A kind of vacuum seal of container

The utility model relates to a kind of vacuum seal of container, particularly a kind of device that food is carried out vacuum freshness retaining.

Existing kitchen vessel is when store food, and freshness date is shorter, even be placed in the reefer of refrigerator, generally also can only deposit several days.Resting period is long, and food will go bad.Utility model patent 94203006.0 and 94245920.2 discloses a kind of sealable tank of vacuum-pumping, formed by tank body, lid, pump bowl, be characterized in also having top cover and pressing plate, top cover is enclosed within the vent plug top, the lid periphery ring is established interior incisxal edge, there are two cross-drilled holes the top cover upper end, and respectively there is the embedding seat two cross-drilled hole both sides, and the embedding post is arranged on the embedding seat; The pressing plate interlocking is above top cover, and there is abaculus the pressing plate below with the embedding seat corresponding section of top cover, and the embedding hole is arranged on the abaculus; There is deck the pressing plate below, and arbitrary cross-drilled hole corresponding section of deck and top cover has hole clipping.Its advantage is to vacuumize tank body, prolongs the storage life to food.Its weak point is that parts are more, has improved manufacturing cost.

The purpose of this utility model provide a kind of simple in structure, can be used for food cans, bottle are vacuumized and leak free vent plug and air extracting pump thereof, make the food can long preservation.

The technical solution of the utility model is: a kind of vacuum seal of container, comprise vent plug of making by flexible material 3 and the air extracting pump 4 that matches with vent plug 3, it is characterized in that: described vent plug 3 lower ends are cylindric, the center is provided with pore 16 and excircle is provided with seal ring 7, the upper end is the circular interface 9 of bleeding, a projection 18 is established at its center, this projection center is provided with an air cleft 6 and communicates with pore 16, interface 9 lower ends of bleeding are provided with a flange 17, are down echelon form between this flange 17 and the seal ring 7 that is adjacent.

Described air extracting pump 4 is made of handle 10, inflator 11, plunger 12, and plunger 12 1 ends and handle 10 are affixed, and the other end and inflator 11 movable fitting surface places establish a compression ring 19.

The utility model can vacuumize and very easy to use food cans, bottle.Make things convenient for the ordinarily resident just can carry out application of vacuum at home, prolong its fresh-keeping and Keeping life food, beverage, wine etc.

Now in conjunction with the accompanying drawings and embodiments the utility model is described as follows:

Fig. 1 is the cut-away view figure of the utility model vent plug;

Fig. 2 is the birds-eye view of the utility model vent plug;

Fig. 3 is the structural representation of the utility model air extracting pump;

Fig. 4 is one of embodiment of the present utility model;

Fig. 5 is two of embodiment of the present utility model.

A kind of vacuum seal of container, comprise vent plug of making by flexible material 3 and the air extracting pump 4 that matches with vent plug 3, vent plug 3 lower ends are cylindric, the center is provided with pore 16 and excircle is provided with seal ring 7, the upper end is the circular interface 9 of bleeding, and a projection 18 is established at its center, and this projection center is provided with an air cleft 6 and communicates with pore 16, interface 9 lower ends of bleeding are provided with a flange 17, are down echelon form between this flange 17 and the seal ring 7 that is adjacent.Air extracting pump 4 is made of handle 10, inflator 11, plunger 12, and plunger 12 1 ends and handle 10 are affixed, and the other end and inflator 11 movable fitting surface places establish a compression ring 19.

Embodiment 1:

The utility model is used for special-purpose vacuum food jar, and the lid 2 of this jar is provided with the T-shape interface slot 13 that matches with vent plug 3, and hole 14 is established in these interface slot 13 bottoms, and cover 15 matches with the lower end of this T-shape interface slot 13.During use, lid 2 is covered on the tank body 1 of depositing food, the bleeding point 5 of air extracting pump 4 and the interface 9 of bleeding of vent plug 3 are matched, upwards spur handle 10, the sky in the tank body 1 can be extracted out.The flow direction of gas is: enter hole 14 through overlapping 15 with the slit that cooperates of T-shape interface slot 13 lower ends, then through the pore 16 of vent plug 3 bottoms, again in air cleft 6 enters the inflator 11 of air extracting pump, and in the tolerance clearance exhaust to atmosphere of inflator 11 and plunger 12.When producing negative pressure in the tank body 1, because difference of pressure, the inclined-plane on 1 mouthful of the seal ring 8 that cover on 2 and the tank body is sucked; Vent plug 3 is adjacent to the bottom of T-shape interface slot, makes seal ring set on the vent plug 37 radially rise big and be mated the face tensioner to seal; Negative pressure also makes air cleft 6 suck simultaneously, thereby reaches the purpose of negative-pressure sealing.

When needs are opened when covering 2, only with hand is gently pinched the interface 9 of bleeding (along the direction of air cleft 6) of vent plug upper end, because vent plug 3 is made for flexible material, deforms after the application of force, air cleft 6 promptly is opened, and ambient pressure promptly enters in the tank body 1 greater than the air of tank body 1 internal pressure.When the tank body external and internal pressure reached balance, lid 2 promptly was opened.

Embodiment 2:

The utility model also can be directly used in bottle.For drinks such as grape wine, open behind the bottle cap if once can not finish off, can influence its taste even can go bad with the commonsense method preservation.Use the utility model only to need that vent plug 3 is replaced common bottle stopper and fill in bottleneck, matched with the bottleneck end face in the lower surface of flange 17.The bleeding point 5 of air extracting pump 4 interface 9 of bleeding with vent plug 3 is matched, upwards spur handle 10, air is in pore 16, air cleft 6 enter the inflator 11 of air extracting pump, and in the tolerance clearance exhaust to atmosphere of inflator 11 and plunger 12 in the bottle.When producing negative pressure in the tank body 1, because difference of pressure sucks flange 17 lower surfaces and the bottleneck end face of vent plug, negative pressure also makes air cleft 6 suck simultaneously, thereby reaches the effect of negative-pressure sealing.

When needs were extracted vent plug 3, only with hand was gently pinched the interface 9 of bleeding (along the direction of air cleft 6) of vent plug upper end, deformed after vent plug that flexible material is made 3 is stressed, and air cleft 6 promptly is opened, and external air pressure is greater than in the bottle and enter in the bottle.At this moment, vent plug 3 can be extracted from bottleneck.
