Manufacture method.
Preferably this snaps connection is permanently connected, and it cannot come off when not damaging container.Selectable, this snaps connection
Can be disengagable, so as to remove upper frame and lid and be for example re-used in another packaging.Preferred according to another
Embodiment, this snaps connection the multiple barbs downwardly extending being included on upper frame, and barb is by determining in underframe
Position opening combines.
First seal of the present invention and the second seal are preferably insect protected seal.Below, insect protected seal will be fixed
Justice is such seal, and it avoids any opening of 70 microns or bigger at any of this seal.Tropical climate
The experience of food packaging applications have determined that this value is typically enough to avoid the entrance of small worm, this small worm can endanger food and defend
Raw.Carry out insect protected by providing the first seal and the second seal, such insect can be avoided to enter inside container, even exist
This container is initially opened rear and is also such when powder particle is present in around lid and framework.This first seal and second
Seal can also be waterproof, preferably prevents the water of at least 3cm.
The first upright wheel rim that preferably this first seal is included on underframe, its combine at upper frame to downward
It in the first groove stretched, is preferably in interference engagement.This first wheel rim and the first groove preferably whole at the first seal
Circumference is constant.Such seal is already significantly better than single-side sealing part.Described wheel rim and groove can hold
It is easily formed and there is interference engagement, and can readily realize above-mentioned insect protected.For the structure being produced by injection molding technology,
Their accuracy depends on the size of structure to be formed.For the groove being smaller in size than 2mm, the manufacture of 3% can be accepted
Tolerance, and do not jeopardize this seal.In the case of single-side sealing part, the critical dimension of described structure will be the integrated straight of opening
Footpath, for the opening of 10cm diameter, same tolerance will produce the change in size of 3mm, and this makes interference engagement be difficult to ensure that.
The second upright wheel rim that preferably this second seal is also included on upper frame, its combine at lid to downward
Stretch in the second groove, be preferably in interference engagement.This second wheel rim and the second groove are preferably at the whole circumference of the second seal

Interval exists, and in corner regions, can even be spaced more closely.By providing the support to the second groove, should
The wall of the second groove can be made more flexible, thus preferably accommodates described second wheel rim.In order to realize their importing work(
Can, import flange and can extend downward beyond the minimum level of the second groove, and be smoothly at an angle of towards this groove or
Person is curved.
The first seal between upper frame and this underframe is generally used for disposably assembling, and does not needs thereafter again close
Envelope.But, the combination of these parts can be carried out with auto-programming, manufactures respective parts subsequently and carries out stress pine to it
Relax.For this reason, this first groove also at least can have similar importing flange at its excircle.This may consequently contribute to
Framework and underframe in an assembling process from centering.
According to a kind of embodiment of the present invention, outside this upper frame can have an excircle skirt section and this lid can have
Surface, and this outer surface and skirt section be coplanar when lid is in the close position.In this sense, coplanar not limit to
In flat surfaces, and also camber to level face can be included.As the result of this shape, this lid and upper frame can form light
Sliding transition, and do not interrupt.
According to a further aspect of the invention, this upper frame has excircle skirt section and this underframe has peripheral surface, and this is outer
Enclosing surface with skirt section is coplanar when upper frame connects together with underframe.As above, this generates upper frame and underframe
Between smoothly transit.
Described lid can manufacture as with upper wheel rim article respectively, and can remove from which.But preferably
This lid is pivotally attached on upper frame.In one embodiment, this lid can arrange and pivot around hinge, this hinge
It is positioned at the radially-inwardly position of the excircle of upper frame.Design in the past is used for hinge arrangement, and it makes lid relative
It is being pivotally connected from the radially outer position of the excircle of wheel rim in wheel rim.The hinge arrangement meeting interference stack of such protrusion,
And can be ugly in final product.
As the result of lid pivoted closed, if it occur that readily close, and do not damage the second seal, then by second
It is important that wheel rim is correctly incorporated into the second groove.Guiding structure is important in realizing such Guan Bi.In order to further
Improving described closed action, second groove downwardly extending of this lid can have circumferential inner wall and outer circumferential walls, wherein should
The distance that outer circumferential walls downwardly extends is more than and the circumferential inner wall in hinge adjacent area.This inwall is therefore at its whole circumference
Height around is not uniform, and can be gradually curved in the middle of the rear side of container gradually downward from the either end of container.
