Abstract
The invention discloses a food preservation package. The food preservation package comprises a bottom support, and a cover buckled on the bottom support, wherein the cover and the bottom support are buckled to form a storage cavity. The food preservation package is characterized in that multiple ventilating holes are formed in a baseplate of the bottom support; a sealing film upwards wraps from the bottom of the outer side of the bottom support, and is sealed with the periphery of the cover; and a preservation warning medium is arranged between the sealing film and the bottom of the outer side of the bottom support. The food preservation package is beautiful in appearance, convenient to open and low in cost, and has a ventilation warning function; and people can identify if the air leakage occurs through eyes, so that the food safety is guaranteed.
Description
Technical field
Patent of the present invention relates to packaging field, particularly a kind of food-preserving packing box.
Background technology
The kind of food fresh keeping packaging is varied, mostly is packed, box-packed or plastic sealing pack etc.Be packaged in certain time limit by these, the quality of in-built food can be ensured, for people's life requirement.Along with growth in the living standard, people for the external packing of food and the requirement of food security more and more higher; But when fresh-keeping packaging is leaked gas, from packaging for foodstuff, people can't learn that whether encapsulation is intact, therefore may peddle or eat by mistake rotten food.So, need a kind of food package box easy to use, that have good safety performance and gas leakage warning performance imperative.
Patent of invention content
The object of patent of the present invention is to provide a kind of food-preserving packing box, not there is to solve existing packing box the technical matters of gas leakage warning performance, safety performance difference, and provide a kind of structure food-preserving packing box simple, easy to use, with low cost.
The technical scheme of the present invention's packaging is:
Food-preserving packing box, comprises collet, the outer cover be fastened on this collet, forms a storage cavity after outer cover and collet fasten.Wherein, the base plate of collet is provided with several breather holes, and diaphragm seal upwards wraps up from the exterior bottom of collet, with outer cover peripheral sealing.Fresh-keeping warning medium is provided with between diaphragm seal and the exterior bottom of collet.
Due to technique scheme, adopt and be provided with breather hole on the base plate of this packing box collet, thus set up package exterior and inner contacting, now more fresh-keeping warning medium is placed between diaphragm seal and collet, ensure that food sanitation safe on the one hand, just very clearly can recognize fresh-keeping foodstuff from package exterior on the other hand and whether there occurs because of gas leakage rotten.
In order to better reach the requirement of packing box leak tightness, as the further improvement of patent of the present invention, diaphragm seal is low oxygen flow food stage complex film.
In order to can the volume of on the one hand extension packets mounted box, ensure food not cracky in transportation on the other hand, further improve as patent of the present invention, the preferred structure of its collet be that the base plate of collet is recessed to form a storing groove downwards; Fresh-keeping foodstuff being blocked motionless by this groove, avoiding in transportation damaged because colliding at packing box.Secondly, in order to fresh-keeping foodstuff transfixion in this groove can be made further, avoid, because the reasons such as transport cause fresh-keeping foodstuff damaged, strengthening grid to be provided with in storing groove.Again, can also by the top of outer cover to lower recess, this depression also can keep fresh-keeping foodstuff transfixion.
In order to make packing box have excellent leak tightness, the one as patent of the present invention is improved, and the neighboring thermoplastic of diaphragm seal and outer cover merges and seals.
Another of patent of the present invention is improved, and outer cover is by low oxygen flow transparent food level plastics high temperature plastics sucking moulding.
The another kind of patent of the present invention improves, and collet is by the one-shot forming of dark coffee look food grade plastic.
By implementing technique scheme, patent of the present invention not only can be one-body molded, thus reduce costs, but also the shape of packing box can be made to present variation, as circle, rectangle, ellipse etc.This packing box because of its outer cover, collet be all one-body molded, so also have the features such as structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of patent of the present invention;
Fig. 2 is the structural representation of outer cover;
Fig. 3 is the cutaway view of collet;
Fig. 4 is the birds-eye view of collet.
In figure: 2. fresh-keeping warning medium, 10. outer cover, 11. outer cover tops, 12. outer cover peripheries, 30. collets, 31. collet base plates, 50. diaphragm seals, 311. breather holes, 312. grooves, 313. strengthening grids.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, patent of the present invention is described in further details.
As shown in Figures 1 to 4, food-preserving packing box, comprises collet 30, and is fastened on the outer cover 10 on this collet 30, and outer cover 10 and collet 30 fasten rear formation one storage cavity.Outer cover 10 and collet 30 are suitable for suitability for industrialized production, stepped expansion, one-body molded.Such as: outer cover 10 is one-body molded by low oxygen flow transparent food level plastics high temperature plastic uptake; Or collet 30 is by dark coffee look food grade plastic one-shot forming etc.Shape both it also can change various, as ellipse, circle, rectangle, square etc., all can meet the packaging demand of different food products.
In order to solution can never have the technical matters that performance, safety performance difference are warned in gas leakage, the base plate 31 of the collet 30 of patent of the present invention is provided with several breather holes 311, collet 30 upwards wraps up from exterior bottom by diaphragm seal 50, and seal with outer cover periphery 12, at this moment just define the fresh-keeping package box of a sealing.In the mode that diaphragm seal 50 and outer cover periphery 12 seal, any sealing means can be adopted, as gluing, hot pressing etc., as long as seal food requirement can be met; What present embodiment adopted is that thermoplastic merges sealing means.
Monitor whether package interior has gas leak phenomenon to occur, and during with diaphragm seal 50 sealing packaging box, is provided with fresh-keeping warning medium 2 between diaphragm seal 50 and the exterior bottom of collet 30 to play.Wherein, in order to reach better sealing property, diaphragm seal 50 adopts low oxygen flow food stage complex film (KOP/CPP/KNY/PE, KPET/PE, PET/AL/PE).
Meanwhile, in order to can the volume of on the one hand extension packets mounted box, ensure food not cracky in transportation on the other hand, the structure design of collet 30 can also be recessed to form a storing groove 312 downwards for its base plate 31; Fresh-keeping foodstuff being blocked motionless by this groove 312, avoiding in transportation damaged because colliding at packing box.Secondly, in order to fresh-keeping foodstuff transfixion in this groove 312 can be made further, avoid, because the reasons such as transport cause fresh-keeping foodstuff damaged, strengthening grid 313 to be provided with in storing groove 312.Again, can also by outer cover top 11 to lower recess, this depressed area (not shown) can push down the food in fresh-keeping package box, makes its transfixion.
Wherein, the fresh-keeping warning medium 2 in present embodiment be band display oxygen absorbent, its effect be by sealing after packing box in oxygen absorption; Meanwhile, also the oxygen depletion that seepage in freshness date is entered in packing box can be fallen.When anaerobic or extremely low oxygen amount (oxygen concentration < 0.1%), oxygen absorbent is pink colour or colourless; When packaging is leaked, during oxygen concentration > 0.3% in packaging, oxygen absorbent is shown as blueness.Therefore, patent of the present invention also has leakage alarm function while guarantee food is fresh, and people can identify whether to leak gas by naked eyes, guarantee food security, eat by mistake in order to avoid buy by mistake.
