Detailed description of the invention
As depicted in figs. 1 and 2, be integral structure schematic diagram of the present invention, this container can be rectangular tank as shown in Figure 1, also can be bulge as shown in Figure 2, this container comprises lid 100 and box body 200, and lid 100 and box body 200 cover mutually, forms the cavity volume of sealing.
Particularly, this lid 100 has caping 110, and caping center is the plane of general planar, is provided with annular groove 130 at centre plane.Extend to form lid side 120 from caping 110 periphery downwards, horizontally outward extend to form lid outer rim 103 from lid side 120.From the protruding lid sealing the margin of lid outer rim 103, described lid sealing the margin comprises upper curved section 1001, transition phase 1002 and lower horizontal section 1003.Wherein, this upper curved section 1001 is annular that upwards bend up, that be connected with lid outer rim 103, and lid side 120, lid outer rim 103 form with the upper curved section 1001 of lid sealing the margin the structure that cross-sectional plane is V-shape.This transition phase 1002 is the annular of general planar, and this lower horizontal section 1003 is decurved annular.Two arc limits of transition phase 1002 connect upper curved section 1001 and lower horizontal section 1003 respectively, and the upper curved section 1001 of lid sealing the margin, transition phase 1002 and lower horizontal section 1003 form the structure that cross-sectional plane is inverted u-shaped.
Wherein, the side that upper curved section 1001 is mutually corresponding with lower horizontal section 1003 is respectively the medial surface of upper curved section 1001 and the medial surface of lower horizontal section 1003, the surface of the transition phase 1002 be connected with the medial surface of lower horizontal section 1003 is the lower surface of transition phase 1002, and the surface of the lid outer rim 103 be connected with the medial surface of upper curved section 1001 is the lower surface of lid outer rim 103.
The barb 1004 protruding from lid sealing the margin is provided with at the medial surface place of lower horizontal section 1003.Be provided with the first sealing flange 1005 at the lower surface of transition phase 1002, this first sealing flange 1005 is concentric circles with this transition phase 1002.The lower surface of lid outer rim 103 is provided with the second sealing flange 1006, and this second sealing flange 1006 is concentric circles with this lid outer rim 103.
It is the plane of general planar that box body 200 has 210, He Di centers at the bottom of box, is provided with annular ridge 230 at centre plane, annular ridge 230 for the leg making box body make box body support on the table.Upwards extend to form box side 220 from box body periphery, horizontally outward extend to form box outer rim 203 from box side 220.From the protruding box sealing the margin of box outer rim 203, box sealing the margin comprises the section of prolonging 2001, linkage section 2002 and downward section 2003.Wherein, on this, the section of prolonging 2001 is annular that upwards bend up, that be connected with box outer rim 203, and box side 220, box outer rim 203 form with the section of prolonging 2001 on box sealing the margin the structure that cross-sectional plane is V-shape.This linkage section 2002 is the annular of general planar, and this downward section 2003 is decurved annular.Two arc limits of linkage section 2002 connect the section of prolonging 2001 and downward section 2003 respectively, and on box sealing the margin, the section of prolonging 2001, linkage section 2002 and downward section 2003 formation cross sectional drawing are the structure of inverted u-shaped.
As shown in Figure 4, lid sealing the margin and box sealing the margin are configured as the shape be fitted to each other, when closing lid, downward section of the lower horizontal section 1003 of lid sealing the margin and box sealing the margin 2003 bonded to each other, barb 1004 clamping of lid sealing the margin also holds up box sealing the margin, makes box sealing the margin be close to lid sealing the margin.First sealing flange 1005 pushes up the linkage section 2002 of pressure box sealing the margin, thus forms the first sealing lip.Second sealing flange 1006 pushes up pressure box outer rim 203, thus forms the second sealing lip.
And, on box sealing the margin, between barb 1004 and the first sealing flange 1005, there is a curved position, place.When closing lid, lid 100 and box body 200 leave gap at this curved position place, form the first blanket gas bubble chamber 301.And between the first sealing flange 1005 and the second sealing flange 1006, be provided with two curved positions, place, when closing lid, lid 100 and box body 200 leave gap at this two curved positions place, form the second blanket gas bubble chamber 303 and the 3rd blanket gas bubble chamber 305.
Traditional airtight container, the rubber seal etc. larger by width seals, and an obstruct granular solids leaks or air is with remarkable result, but, poor to the barriering effect of liquid type, generally can not prevent as dish juice, soup class are exosmosed.And the present invention adopts sealing flange, the width of flange is little, and by barb by lid and the mutual clamping of box body, then obtains large pressure when pushing up pressure, and significant sealing affection, even the content of liquid type, also can prevent from exosmosing.Moreover the present invention adopts two sealing flanges, form the first sealing lip and the second sealing lip, set up twice defence line, isolate the content of airtight container of the present invention well with extraneous.
Further, caping 110 annular groove 130 with at the bottom of box 210 annular ridge 230 there is the projected position that overlaps and be configured as the shape be fitted to each other, when box body 200 is positioned over lid 100 top, in described annular ridge 230 embedded rings connected in star 130.Such structure makes lid 100 can be positioned over reposefully after opening below box body 200, reduces to occupy space.
As Fig. 3 is also shown in, described lid side 120 extends to form downwards with angle that is substantially vertical or that expand outwardly from caping 110, makes multiple lid 100 can mounted on top.Described box side 220 210 upwards to extend to form with angle that is substantially vertical or that expand outwardly at the bottom of box, makes multiple box body 200 can mounted on top.After lid 100 and box body 200 assemble by mode shown in Fig. 3, multiple lid 100 can also being stacked layer by layer above lid 100, and below box body 200, also can stack multiple box body 200 layer by layer, making like this can reduce display space when selling or family receives.
The box side 220 of described box body 200 210 upwards gradually broadly to extend at the bottom of described box, and forms two ladder table tops.Box body is made not to be subject to external force deformation.
Described box body 200 and lid 100 adopt plastics or elastomeric material manufacture, make box body 200 and lid 100 have certain plasticity.
The present invention is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or modification, if these are changed and modification belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these change and modification.
