To be simple, more and more it is applied to packaging field.
The existing type packing jar that is connected, is often attached between tank bottom and tank body by the way of compressing,
But although this connected mode, than stronger, for the elastic reaction of material itself, sealing is typically not capable of requirement,
In packaging, in order to ensure sealing effectiveness, typically also need to be packed using one layer of even multi-layer sealed bag, thus not only increase
The consumption of packaging material is added, and packaging process is more, adds packing cost.
Utility model content
The purpose of this utility model is to provide a kind of bottom configuration for strengthening sealing effectiveness.
According to one side of the present utility model, there is provided it is a kind of strengthen sealing effectiveness bottom configuration, including tank body and
Located at the tank bottom of tank base, tank body is hollow tubular construction, and tank bottom has the bottom that a shape matches with tank body cross section
Face, bottom surface are located at the middle part of tank bottom, and bottom periphery forms edge portion to the same side bending, and edge portion fits with inner tank wall,
An adhesive linkage is additionally provided between edge portion and tank base inwall, tank bottom is tightly connected with tank body by adhesive linkage.
Using the bottom configuration of the reinforcing sealing effectiveness of above technical scheme, the bottom configuration of existing tank body is carried out
Improve, by increasing edge portion and adhesive linkage, tank bottom and tank body is closely connected as one, so as to substantially increase the close of tank body
Feng Xing.Typically can direct packing article using the packing jar of the structure, it is not necessary to using one layer of even multi-layer sealed bag, thus
The consumption of packaging material is not only reduced, and packaging process is few, and packing cost is greatly lowered.
In some embodiments, adhesive linkage is hot melt adhesive layer, polyurethane glue-line, epoxy adhesive layer, starch glue-line or PE
Glue-line.Thus tank bottom connects more close with tank body.
In some embodiments, edge portion extends downwardly along tank base inwall.
In some embodiments, the height in edge portion is 1cm~3cm.
In some embodiments, 95 °~110 ° of the angle between edge portion and bottom surface.Due to the shape and tank body of bottom surface
Cross section it is corresponding, by the angle more than 90 °, edge portion can apply outside pressure on top surface to tank interior, so as to
To strengthen the bond strength between tank bottom and tank body.
In some embodiments, edge portion inside convolution and connects as one together with tank base.
In some embodiments, edge portion is with forming a circle inner bead after the inside convolution of tank base.By to tank body
Bottom carries out the processing of special inner bead structure, further enhances the sealing property and bonding strength of tank base.
In some embodiments, the cross section of tank body is circle, quadrangle, hexagon or octagon.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the bottom configuration of the reinforcing sealing effectiveness of embodiment of the utility model.
Fig. 2 is the structural representation of the tank interior for the bottom configuration for strengthening sealing effectiveness shown in Fig. 1.
Fig. 3 is the sectional view of the tank bottom for the bottom configuration for strengthening sealing effectiveness shown in Fig. 1.
Fig. 4 is the structural representation of the bottom configuration of the reinforcing sealing effectiveness of the utility model another embodiment.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
Fig. 1 to Fig. 3 schematically shows the tank of the reinforcing sealing effectiveness according to a kind of embodiment of the present utility model
Bottom structure.
As illustrated, the structure includes tank body 1 and the tank bottom 2 located at the bottom of tank body 1.
Tank body 1 is hollow columnar structured.
Tank bottom 2 has the rounded bottom surface 21 that a shape matches with the cross section of tank body 1.
Bottom surface 21 is located at the middle part of tank bottom 2.
The periphery of bottom surface 21 forms edge portion 22 to the same side bending.
Edge portion 22 fits with the inwall of tank body 1.
An adhesive linkage 3 is additionally provided between edge portion 22 and the bottom interior wall of tank body 1.
Tank bottom 2 is tightly connected with tank body 1 by adhesive linkage 3.
To cause tank bottom 2 and tank body 1 connects more close, adhesive linkage 3 can be hot melt adhesive layer, or polyurethane adhesive
Layer, epoxy adhesive layer, starch glue-line or PE glue-lines.
To ensure the degree of being connected firmly between edge portion 22 and tank body 1, the height h in edge portion 22 be generally 0.3cm~
3cm。
In the present embodiment, the angle a between edge portion 22 and bottom surface 21 is 100 °.In other examples, edge
Also promising 90 ° or 110 ° of angle a between portion 22 and bottom surface 21.Because the shape of bottom surface 21 is relative with the cross section of tank body 1
Should, by the angle more than 90 °, edge portion 22 can apply outside pressure on top surface to the inside of tank body 1, so as to strengthen tank bottom
Bond strength between 2 and tank body 1.
In other examples, the cross section of tank body 1 can also be that quadrangle, hexagon or octagon etc. are polygon
Shape.
Using the bottom configuration of the reinforcing sealing effectiveness of above technical scheme, the bottom configuration of existing tank body is carried out
Improve, by increasing edge portion and adhesive linkage, tank bottom and tank body is closely connected as one, so as to substantially increase the close of tank body
Feng Xing.Typically can direct packing article using the packing jar of the structure, it is not necessary to using one layer of even multi-layer sealed bag, thus
The consumption of packaging material is not only reduced, and packaging process is few, and packing cost is greatly lowered.
