Though it is comparatively laborsaving when opening and closing up between the lid of above-mentioned patent structure and the box body, but need set out the groove and the flange of non-regular shape at the outer surface at lid inboard and box body edge, the structure relative complex of these grooves and flange, increase the moulding difficulty of lid and box body, improved design and manufacturing cost.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of simple in structure and depository dish lid with better leak tightness is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the lid of this depository dish, it is characterized in that: include loam cake and bottom, the lower end of described bottom links to each other with the depository dish body, the upper end of described bottom is contained within the described loam cake, wherein, the radially overhanging formation one circle rib of the upper end edge of described bottom, all side inwalls of described loam cake then are provided with annular groove, described rib is fastened in this groove and makes described bottom and loam cake be connected in one, and forms one between all side inwalls of described loam cake and all side outer walls of bottom and can hold the opening edge of described depository dish body along the bayonet socket that stretches into.
In order to improve lid and body bonded assembly leak tightness, guarantee lid and body bonded assembly tight ness rating, the lower end outer wall of described bottom is provided with grommet type seals along circumferentially offering draw-in groove in this draw-in groove.
In order to guarantee the side seal of seal ring and body, guarantee that simultaneously lid can successfully snap onto on the body, the cross section of described grommet type seals is Z-shaped, the upper surface at sealing circle top and the rib of described bottom bottom offset, the lower surface at sealing circle top then with the opening edge of described depository dish body along offseting, the opening madial wall of the sidewall of described seal ring and described depository dish body offsets.
In order to realize being connected of loam cake and bottom, also make things convenient for both dismountings simultaneously, all side inwalls of described loam cake are provided with the inwardly convex tendon of protuberance of a circle, form described annular groove between all side inwalls of the convex tendon of described loam cake, loam cake and the inner bottom surface of loam cake.
Consider the comfort feature that lid is opened, prevent to skid that the cross-sectional plane of described loam cake and bottom is square, and described loam cake also is provided with anti-skidding portion on the corner.
Compared with prior art, advantage of the present utility model is: lid has adopted loam cake and bottom bonded assembly unitized construction, make loam cake and bottom cooperate the installation back to form an opening edge that can hold body naturally along the bayonet socket that stretches into, need not to set out the groove and the flange of non-regular shape at the outer surface of lid, simplify the technology of processing and manufacturing, reduced design difficulty; And the connection structure of loam cake and bottom is simple, realizes both connection by rib and recessinterengaging means, convenient installation, dismounting and cleaning, and practicality is stronger.
Description of drawings
Fig. 1 is the three-dimensional exploded view of the utility model embodiment.
Fig. 2 is the assembly structure figure of lid shown in Figure 1.
Fig. 3 is that the lid of the utility model embodiment is installed to the cutaway view on the body.
Fig. 4 is the partial enlarged drawing of I shown in Figure 3 portion.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1～shown in Figure 4, lid structural representation and scheme of installation for present embodiment, this lid adopts plastic material, include square loam cake 1 and transparent square bottom 2, wherein, the radially overhanging formation one circle rib 21 of the upper end edge of bottom 2, all side inwalls of loam cake 1 are provided with a circle inwardly protuberance and cross section convex tendon 11 triangular in shape, this convex tendon 11, form annular groove 4 between all side inwalls of loam cake 1 and the inner bottom surface of loam cake 1, the rib 21 of bottom 2 upper ends promptly is fastened in this groove 4 and makes bottom 2 and loam cake 1 be connected in one, simultaneously, also form one between all side inwalls of loam cake 1 and all side outer walls of bottom 2 and can hold the opening edge of depository dish body 6 along the bayonet socket 5 that stretches into, so,, lid integral body can be withheld on depository dish body 6 the opening edge edge of bayonet socket 5 aligning depository dish bodies 6.
