Abstract
A suction pressure seal box comprises a box body and a box cover covering the box body. The box cover is made of plastic and is provided with an air hole which can be opened or closed. The structure of the connecting site of the box cover and the box body is as follows: a U-shaped groove and a bulge are correspondingly arranged on the outer edge of the box cover and the upper edge of the box body respectively, and the bulge is inserted into the U-shaped groove; and a transverse lateral flange is arranged on one side of the opening end of the U-shaped groove and partially covers the opening end of the U-shaped groove, so that the opening of the opening end is smaller than the thickness of the bulge. Compared with the prior art, the suction pressure seal box has the advantages of simple structure, convenient use, good sealing effect and low cost. The box is made of glass, ceramic or metal, and the box cover is made of plastic or rubber.
Description
Technical field
The utility model relates to airtight container, specifically is a kind of negative-pressure sealing box.
Background technology
In the prior art, the application of seal box is more and more.But the hermetically-sealed construction of seal box of the prior art is too complicated, and the production difficulty is big, the cost height.Especially the seal box of some all-plastic materials in case be heated, then can soften, and influences sealing effectiveness, even adopt special plastic, this situation also is inevitable, and feed stock cost can increase.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of seal box, and concrete technical scheme is as follows:
A kind of negative-pressure sealing box comprises box body and lid, and lid covers on box body; Described lid is a plastic material, but lid is provided with the pore of switch; The structure of described lid and box body junction is, lid outer rim and described box body upper limb are provided with cooresponding " U " shape groove and projection, and projection stretches into " U " shape groove; Be provided with lateral flanks on one side of the open end of " U " shape groove, this flank is sealed the part open end of " U " shape groove, makes the thickness of open end opening less than described projection.
Described box body is the hard material, for example glass, pottery or metal etc.
Described lid is provided with and the cooresponding port lid of described pore, and port lid and lid flexibly connect, and port lid is provided with and the cooresponding stopple of described pore.The material of described stopple is a silica gel; When not filling on described pore, the diameter of stopple is greater than the diameter of pore.Described port lid is provided with time scale sign, and time scale circularizes, and is provided with rotatable pointer in the middle of annular, the user in use can rotary indicator to corresponding time scale, but be used for the assisted memory storage time.
Described " U " shape groove and lateral flanks are rigidity, and described projection is a plasticity.Perhaps, described " U " shape groove and lateral flanks are plasticity, and described projection is a rigidity.
As improving 1, described groove is located on the outer rim of lid, and is vertical with plane, lid place; Described projection is located on the box body upper limb; Projection stretches into groove.
As improving 2, described groove is located on the outer rim of lid, with lid place plane parallel or overlap; Described projection is located on the box body upper limb; Projection stretches into groove.
Compared with prior art, the utility model is simple in structure, and is easy to use, good sealing effect and with low cost.Cell material can be used glass, pottery or metal etc., and the lid material can be used plastics, rubber etc.

Fig. 3 is the cutaway view vertical with Fig. 2 direction.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
A kind of negative-pressure sealing box comprises box body 1 and lid 2, and lid 2 covers on box body 1; Described lid 2 is plastic materials, but lid 2 is provided with the pore 3 of switch.Described lid 2 with the structure of box body 1 junction is, lid 2 outer rims and described box body 1 upper limb are provided with cooresponding " U " shape groove 4 and projection 5, and protruding 5 stretch into " U " shape groove 4; Be provided with lateral flanks 6 on one side of the open end of " U " shape groove 4, this flank 6 is sealed the part open end of " U " shape groove 4, makes the open end opening less than described protruding 5 thickness.
Described box body 1 is the hard material, for example glass, pottery or metal etc.
Described lid 2 is provided with and described pore 3 cooresponding port lids 7, and port lid 7 flexibly connects with lid 2, and port lid 7 is provided with and described pore 3 cooresponding stopples 10.The material of described stopple 10 is a silica gel; When not filling on described pore 3, the diameter of stopple 10 is greater than the diameter of pore 3.Described port lid 7 is provided with time scale sign 8, and time scale circularizes, and is provided with rotatable pointer 9 in the middle of annular.
In this example, if described " U " shape groove 4 and lateral flanks 6 are rigidity, then described protruding 5 is plasticity.If described " U " shape groove 4 and lateral flanks 6 are plasticity, described protruding 5 is rigidity.
This example 1, described " U " shape groove 4 is located on the outer rim of lid 2, and is vertical with plane, lid 2 place; Described protruding 5 are located on box body 1 upper limb, as upper limb itself; Projection stretches into " U " shape groove 4.
As another example 2, described " U " shape groove is located on the outer rim of lid, with lid 2 place plane parallel or overlap; Described projection is located on the box body upper limb; Projection stretches into groove.
