Abstract
The utility model discloses a self-locking type vacuum fresh-keeping box, which is characterized in that the periphery of a box cover is provided with a circle of sealing groove buckled with a box body. A circular hollow sealing ring is arranged in the sealing groove. The upper central part of the box cover is inwardly concave to be provided with a vent hole and an exhaust apparatus, wherein the exhaust apparatus is matched with a vacuum pump to use. The exhaust apparatus consists of a flat sheet type film one-way valve, an exhaust push rod and a one-way valve cover. The flat sheet type film one-way valve is covered onto the vent hole in the box cover. The exhaust push rod is fixed onto the box cover to be connected with the side surface of the flat sheet type film one-way valve. The one-way valve cover is threadedly connected with the box cover to be fixed above the flat sheet type film one-way valve. The one-way valve cover is internally provided with at least one fixed column to fix the flat sheet type film one-way valve onto the vent hole in the valve cover. The self-locking type vacuum fresh-keeping box is simple to manufacture, large in effective volume, long in fresh-keeping time and durable.
Description
Technical field
The utility model belongs to food fresh keeping vessel technical field.
Background technology
For the ease of the depositing and carrying of food, food fresh keeping vessel are widely used.The structure that conventional food preserving box adopts is in the market: on lid, with plastics earclip and the fastening of box body side, be also provided with sealing band and realize the leakproofness of food preserving box between lid and box body.This type of crisper can effectively completely cut off contacting of food and outside air in box, has extended the fresh keeping time of food, but air in box body cannot effectively discharge, and fresh keeping time is short, simultaneously on lid with the use of plastics earclip of a specified duration easy fracture.
In order to discharge the gas in food preserving box, now also can be common on market above lid band establish blow off valve, on lid with plastics earclip or without the food preserving box of earclip; In box, gas part is discharged and is formed negative pressure, has extended to a certain extent the fresh keeping time of food in box.Utilize principle of negative pressure, on lid, can also can guarantee without earclip the leakproofness of product, but that sealing band on lid enters container is too many, affect box body internal volume.
Summary of the invention
The purpose of this utility model is just to provide between a kind of lid and box body earless and links and connect, and it is long that internal tank can form negative pressure fresh keeping time, and box body effective volume is large, manufacture simple, long-lived food preserving box.
Realizing above-mentioned technical purpose the technical solution adopted in the utility model is: self-locking type vacuum crisper, comprise lid, box body, lid periphery is provided with a circle seal groove and box body is interlocked, in seal groove, be provided with circular hollow seal ring, the exhaust gear that in lid top center, recess is provided with deflation hole and is used in conjunction with vacuum pump, described exhaust gear is by sheet type film one way valve, exhaust push rod, and unidirectional valve gap forms, sheet type film one way valve covers on lid deflation hole, exhaust push rod is fixed on lid and joins with sheet type film one way valve side, unidirectional valve gap and lid spin by screw thread, be fixed on the top of sheet type film one way valve, in unidirectional valve gap, being provided with at least one fixed leg is fixed on sheet type film one way valve on lid deflation hole.
The diameter of described circular hollow seal ring is the more than two times of box body wall of container thickness, has effectively avoided because of the inaccurate sealing gas leak phenomenon causing of box body manufacturing dimension.
The side of described circular hollow seal ring is provided with exhaust hole, can keep its inner constant voltage.
The bottom land central authorities of described seal groove are provided with the potted line of a circle to notch direction projection, have strengthened the sealing effectiveness of lid and box body.
The beneficial effects of the utility model are:
1, this interiors of products can form negative pressure, and lid and box body are tightened up, and difficult drop-off, does not need to be with earclip on lid, manufacture simply, the hidden danger that do not rupture is durable in use;
2, circular seal ring two sides in this product lid seal groove have exhaust hole, can keep constant voltage, easily realize negative pressure;
3, the diameter of circular seal ring be a box body container ancient piece of jade, round, flat and with a hole in its centre thick more than 2 times; Can effectively avoid box body because of the inaccurate sealing gas leak phenomenon causing of manufacturing dimension;
4, this product film formula check valve, if rubber plain film just can, manufacture simple, with low cost, easy to clean, sealing reliably.
5, the seal ring of this product can not encountered food, can not reduce vessel volume.
6, after this product accommodating food, do not put into refrigerator, can extend food preservation time, especially summer yet and can solve the vast friend's worry that carries lunch.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model uses view.
The specific embodiment
As shown in Figure 1 and Figure 2, self-locking type vacuum crisper, comprises lid 3, box body 1, and lid 3 peripheries are provided with a circle seal groove and box body 1 is interlocked, and are provided with circular hollow seal ring 2 in seal groove; The diameter of circular hollow seal ring 2 is the more than two times of box body 1 wall of container thickness, has effectively avoided because of the inaccurate sealing gas leak phenomenon causing of box body 1 manufacturing dimension; The side of circular hollow seal ring 2 is provided with exhaust hole, can keep its inner constant voltage;
The bottom land central authorities of seal groove are provided with the potted line 7 of a circle to notch direction projection, have strengthened the sealing effectiveness of lid and box body;
The exhaust gear that in lid 3 top center, recess is provided with deflation hole and is used in conjunction with vacuum pump, described exhaust gear is by sheet type film one way valve 5, exhaust push rod 6, and unidirectional valve gap 4 forms, sheet type film one way valve 5 covers on lid deflation hole, exhaust push rod 6 is fixed on lid 3 and joins with sheet type film one way valve 5 sides, the front end of exhaust push rod 6 has a tiltedly shovel, while needing exhaust, can realize venting as long as promote exhaust push rod 6 to the direction of sheet type film one way valve 5, loosen exhaust push rod 6, utilize the elasticity of sheet type film one way valve 5 that promotion exhaust push rod 6 is automatically reset,
While vacuumizing with vacuum pump 8, sheet type film one way valve 5 can open small gap, allows Bas Discharged in container, while not vacuumizing, can sheet type film one way valve 5 be pressed on lid deflation hole firmly by bar pressure, plays sealing function.Unidirectional valve gap 4 can often remove cleaning, to guarantee clean hygiene.
