Description

A kind of structure improved air hermetic crisper

Technical field

The utility model belongs to the container in a kind of family daily necessity, and especially a kind of box of using in refrigerator or the micro-wave oven of being suitable for relates to the improvement of the airtight construction of this box.

Prior art

Food at open space, tends to be subjected to dust and contamination by micro in the air as if long term exposure, and has part food to absorb airborne moisture easily, produces peculiar smell and cause food that rotten reaching taken place.Therefore, existing crisper as shown in Figure 6, is made up of a box body 80 and a lid 90, is provided with several projections 81 at box body 80 upper limb lateral wall places, and extends outward on several adapter plates 91 slotted eye 92 that forms in correspondence with each other with lid 90.Referring again to shown in Figure 7, it is the section-drawing of aforementioned crisper.When lid 90 upper shields were on box body 80, lid 90 was fixed on the projection 81 of box body 80 by the slotted eye 92 of adapter plate 91, made can captive joint between lid 90 and the box body 80.Yet, this kind mode is because the need when making this crisper of the relative position between projection 81 and the slotted eye 92 are very accurate, otherwise will cause sealing effectiveness bad, and the possibility of sealed poor effect is also arranged, and the projection of this class box or slotted eye are symmetrically distributed usually, with regard to use, the user wishes needn't recognize direction that when lid covers promptly for rectangle box, lid can turn over 180 ° and still box body can be covered; For square box, lid can turn over 90 ° and still all box body can be covered, therefore, accurate distribution on box body or lid proposes higher requirement for projection or slotted eye, thereby further increases the difficulty on making, in addition, box body is because the projection on the edge, both influence the attractive in appearance of shape, sheltered evil people and countenance evil practices easily again, cleaned more apparent trouble.This kind structure also must make projection 81 aim at mutually and often must rotate a certain angle and adjust both positions, more apparent inconvenience in the use with slotted eye 92 if be applied on the columned crisper during use.

Summary of the invention

The purpose of this utility model is the crisper that a kind of more advanced air hermetic structure will be provided.

Comprise by reaching the major technique means that above-mentioned purpose taked:

One box body, its lateral wall extend to form the overhead kick shape clasp in a h type cross section of giving prominence to horizontal direction near end envelope wall bottom on the opening.

One lid forms fourth type cross section in the buckle place of buckle ear, as the be connected engagement section of box body with lid.

When user's desire during with box body and lid driving fit, only need buckle ear jam plate with lid to pressing down, make this engagement section to take advantage of a situation and enter in this overhead kick portion, utilize envelope wall, the sealing rubber ring compressive deformation that places seal groove and be close to lid and the full face contact face of box body on, in the isolated box, the connection of outer air, further make the food minimizing that is placed in the box be subjected to dust and microbial contamination chance in the air, and avoid in the open space in the air contained moisture to be absorbed and cause food spoilage and produce peculiar smell, therefore reach and preserve the fresh purpose of food by food.

The crisper of the invention, the mode that does not adopt projection to cooperate with slotted eye realizes the fastening between box body and the lid, thereby does not have projection and the inaccurate problem that may cause sealing effectiveness and sealed poor effect of slotted eye relative position.

Crisper of the present utility model is that the employing button hook is realized the fastening between box body and the lid with cooperating of clasp, thereby can reduces the manufacturing accuracy rate of fastening part position distribution, and then makes manufacturing easier.

This creation also because clasp and button hook between box body and the lid fasten mutually, can fully be compressed the O-ring seal that is positioned at groove, and then can fully be filled the slit between box body and the lid, thereby has obtained the crisper that a kind of air-tightness further promotes.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Consulting Fig. 1 and shown in Figure 2, is the External view and the local amplification view of the utility model one preferred embodiment.This box mainly is to comprise:

One box body 20 can be for square, cuboid, also can be cylinder or other solids, and as envelope wall 22, horizontal direction extends to form the overhead kick portion clasp 21 in an outstanding h font cross section with lateral wall upper end around it.

One lid 10, can be square, cuboid, also can be cylinder or other solids, be centered around this lid periphery outer ring and establish formation one bonded assembly connecting portion 11, this connecting portion forms a spill seal groove 12, these connecting portion 11 inboards 18 can be inserted in by the opening part of box body 20,17 of external side ends are enclosed within the top of the overhead kick portion clasp 21 of box body 20, in this spill seal groove 12, be provided with a rubber-like packing element 30, this packing element 30 can be the O-ring seal that silaatic is made, and these connecting portion 11 relative external side ends are to be provided with four buckle ear jam plates 13, four buckle ear jam plates 13 are divided on four limits of lid 10, buckle ear jam plate 13 inwardly shortens a comparatively thin thin and bent bending edge 14 on one side into, this bending edge 14 is connected with connecting portion 11, the inboard of this buckle ear jam plate 13 forms a slice buckle 15, and buckle 15 is as the effect of compressing flexible rubber ring, and the inboard of buckle 15 forms a protruding button hook 16, button hook can guarantee that the buckle ear jam plate leans against on the vertical surface of box body behind fastening.

Consult Fig. 3 and shown in Figure 4, it is the local amplification profile action diagram of the foregoing description.After the user inserts the box of this creation with food, again with these lid 10 upper shields on box body 20, with hand this lid buckle ear jam plate 13 is bent downwards, make 20 of lid 10 and box bodys to combine closely, the interior packing element O-ring seal 30 of lid 10 is located in compression simultaneously, make the overhead kick clasp 21 that the protruding button hook 16 of buckle 15 inboards of buckle ear jam plate 13 can be taken advantage of a situation and be slipped into box body 20 with a suitable angle, and be fixed on side within the overhead kick clasp 21, this moment is because the external force disappearance on the lid 10, make 30 attempts of packing element can reply its original volume size, further the slit of lid 10 and 20 junctions of box body is filled up, the chance of the air admission that further stops external world to the box body 20, so reach the leak free effect.

Consulting shown in Figure 5ly, is the External view of another preferred embodiment of the utility model.The lid 10 and the box body 20 of present embodiment are shaped as cylindrical, therefore the user can be according to own demand own, select the crisper of difformity, and because this creation system utilizes this box body 20 to be provided with the overhead kick clasp 21 of continuous shape and the buckle mutual action on lid 10 formed four buckle ear jam plates 13, button hook enters after the clasp 21, can guarantee that buckle ear jam plate 13 is near clasp 21, make that being connected of 10 of box body 20 and lids can be more preferably tight, further solve existing crisper easily because the relative position between projection and slotted eye if during inaccuracy, then cause sealing effectiveness bad, and the possibility of sealed poor effect is arranged and solve lid and problem that the box body optional position all can fasten, more convenient use more demonstrates creativeness of the present utility model.

Claims (3)
