Abstract
The utility model relates to a stainless steel fresh-keeping box for food, which comprises the following components: a box cover, a box body, a sealing ring, base fixing sheets, compressing hooks, a handle, and a unidirectional valve. The vacuum sealing ring is provided between the box cover and the box body for preventing ventilation between the air in and out the box. The base fixing sheets are welded at two sides of the box body. Furthermore the two sides are provided with the compressing hooks. The compressing hooks are buckled for preventing leakage. The air in the box is pumped out through a ventilation cylinder. The unidirectional valve prevents air flow for ensuring the air in the box can be pumped out and the air outside the box can not enter, thereby restricting bacteria invasion and realizing fresh keeping of the food. The fresh-keeping box for food is made of stainless steel, thereby ensuring no chemical pollution of the food.
Description
Technical field:
The utility model is a kind of environmental protection, fresh-keeping food utensil, belongs to the dining utensil field.
Background technology:
Sometimes need carry food in the daily life; Storage food, fresh-keeping foodstuff, popular in the market is the food box of plastics mostly; The plastic-food box has easily manufactured advantage, and plastic molecules permeates and the plasticiser decomposition has certain hidden danger to food security but have.In addition can not fresh-keeping foodstuff, summer food in box, surpass and will go bad half a day.
Summary of the invention:
Defective to prior art; Make full use of the safe reliability of corrosion-resistant steel to food; According to air is the basic reason that causes food spoilage, and temperature is the mechanism of external cause, and the technology that " no air is fresh-keeping " of adopting food to exempt from ingress of air reaches " self-healing sealing " realizes food fresh-keeping.Seal ring interference compression simultaneously makes closed contact between lid and the box body, even do not vacuumize the juice that also can not leak food in the box, is easy to carry.Embodiment:
The utility model is realized through following technical scheme: exempt from ingress of air in order to make food; Adopt the technical scheme of getting rid of air in the box, utilize pump bowl to extract air in the box, check valve check air flows; Can be drawn out of with gas in the assurance box, and the outer gas of box can not get into.Another effect of one-way valve is the display box internal gas pressure, and after gas was excluded in the box, the air valve top spherical of just putting was recessed, and its recessed degree is by degree of vacuum decision in the box.
Sealing between box body and lid is that major technology is crucial; Specific embodiments is the seal ring of hollow in addition between box body and lid, when bleeding with pump bowl, and air expansion in the seal ring; Make between box body and the lid contact tighter; Because bar pressure is pressed on lid, make pressure increasing between box body, lid and the seal ring simultaneously, so form the self-healing sealing.
Description of drawings
Fig. 1 is the cutaway view that the pump bowl of the utility model extracts gas in the food preserving box;
Fig. 2 is the cutaway view of the utility model pump bowl;
Fig. 3 is the utility model lid, box body is with seal ring and compress the cutaway view that hook cooperates;
Fig. 4 is the cutaway view of the utility model lid and check valve:
Label title among the figure is following:
(1) lid; (2) seal ring; (3) box body; (4) base fixed plate; (5) compress hook; (6) lid fixed plate; (7) handle; (8) check valve; (9) cylinder base; (10) piston barrel; (11) cover; (12) seal ring; (13) piston; (14) pull bar; (15) handle
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Shown in accompanying drawing 1, put into food in the box body of fresh-keeping foodstuff box (3) after, lid (1) is built, and is hooked lid (3) with the hook that compresses at two ends, aim at check valve (8) with pump bowl then and bleed, until check valve (8) upper end hemisphere face depression.
Shown in accompanying drawing 2, (10) piston barrel is that pipe is processed, and a cylinder base (9) is joined in the bottom; Cover (11) is joined in the upper end, in the tube seal ring (12) is housed, and is furnished with piston (13) pull bar (16) and handle (15); Pump bowl is pressed on the check valve, comes and goes and twitch handle (15), to reach the vacuum of food box.
Shown in accompanying drawing 3, a hollow sealing circle (2) is arranged between lid (1) and box body (3), be welded with end fixed plate (4) in box body (3) both sides, and be equipped with and compress hook (5), buckle and can not leak food juice in the box after compressing hook.
Be shown in lid (1) center like 4 in accompanying drawing check valve (8) is housed, check valve (8) air can only be extracted out, can not get into, and check valve (8) upper end semicircle sphere is sagged, and air has been removed totally in the expression box.
The utility model is than popular in the market more environmental protection of plastic-food box, and is safer.And have the function of crisper again, and will bring more health to people's life, convenient and economical.
Claims (3)
1. a corrosion-resistant steel food preserving box comprises: lid, box body, seal ring; The base fixed plate compresses hook, handle, check valve; It is characterized in that the seal ring of a vacuum is arranged between lid and the box body, be used to the airiness that stops box inside and outside; The box body both sides are welded with the base fixed plate, and are equipped with and compress hook, buckle to compress hook and be used to prevent reveal.
2. corrosion-resistant steel food preserving box according to claim 1 is characterized in that check valve display box internal gas pressure, and after gas was discharged in the box, the air valve top sphere of just putting was recessed.
