Abstract

A thin packing cover needs some pressing and bending process to stick the packing material into the main cover. This inventory is the packing cover which can be manufactured without bending or pressing the main cover by the processing of double injection molding method that can inject the packing plastic material from upper and under packing place of the main cover.

Description

The airtight container cover that adopts double injection molding method to make
Background of invention
Invention field
The container cover that the present invention relates to be made of plastics, particularly a kind of container cover, its rate of pressurization increases, and soft mode prepared material and die prepared material can bond together mutually, thus after molded finishing, lid is flat-satin more.
In recent years, prior art is the container cover that employing double injection molding (doubleinjection molding) method shown in Figure 6 is made.At first make the body 11 of lid 10.Then, on the outward flange of lid, make one by double injection molding method and be used for the part 10a that combines with container 20 with soft material.Constituted body 11 like this, thereby bound fraction 10a is owing to its soft viscosity has higher air-tightness.
But there is following problem in this prior art, comes off and warpage occurs when cold meeting as the part that hides, and makes lid no longer smooth, smooth.This is the difference owing to the molded condition of the body 11 of lid, and the body 11 of lid is molded with the thickness of 1mm usually, is 0.1mm and adopt the thickness of the molded lid of bridging method.
Therefore, in order to prevent this warpage, as shown in Figure 7, when main body 11 and bound fraction 10a are formed as one, inside part at bound fraction 10a applies processing with soft material, thereby coated part 13 is owing to its viscosity has better air-tightness.
But, be difficult to only inside part be applied processing.And because coated part is connected with body 11, therefore coated part can be peeled off after all.
Summary of the invention
Therefore, in order to address the above problem, when by double injection molding method when the inside part of bound fraction 10a forms coating, described coating is outstanding to the top through hole on the lid or opening portion, thereby increased air-tightness, outward appearance is more attractive in appearance, can not separate in the coating that the inside of bound fraction 10a forms.
Brief Description Of Drawings
Fig. 1 is a block diagram, shows the embodiment of the invention.
Fig. 2 is a block diagram, shows the hole on the lid.
Fig. 3 is a block diagram, shows the opening portion that substitutes described hole.
Fig. 4 is a section drawing, shows the structure of outer wall.
Fig. 4 A is a section drawing, shows the structure of inwall.
Fig. 5 is a block diagram, shows the perforation on the container cover.
Fig. 6 is the section drawing by the prior art embodiment of double injection molding method manufacturing.
Fig. 7 is a section drawing, shows the coating of prior art.
Preferred embodiment describes in detail
The present invention relates to a kind of container cover that is made of plastics, particularly a kind of container cover, its rate of pressurization increases, and soft mode prepared material and die prepared material can bond together mutually, thus after molded finishing, lid is flat-satin more.
In recent years, prior art is the container cover that employing double injection molding method shown in Figure 6 is made.At first make the body 11 of lid 10.Then, on the outward flange of lid, make one by double injection molding method and be used for the part 10a that combines with container 20 with soft material.Constituted body 11 like this, thereby bound fraction 10a is owing to its soft viscosity has higher air-tightness.
But there is following problem in this prior art, comes off and warpage occurs when cold meeting as the part that hides, and makes lid no longer smooth, smooth.This is the difference owing to the molded condition of the body 11 of lid, and the body 11 of lid is molded with the thickness of 1mm usually, is 0.1mm and adopt the thickness of the molded lid of bridging method.
Therefore, in order to prevent this warpage, as shown in Figure 7, when main body 11 and bound fraction 10a are formed as one, inside part at bound fraction 10a applies processing with soft material, thereby coated part 13 is owing to its viscosity has better air-tightness.
But, be difficult to only inside part be applied processing.And because coated part is connected with body 11, therefore coated part can be peeled off after all.
