Description
Technical field
It the utility model is related to food package, more particularly to a kind of plastic casing of self sealss.
Background technology
Boxed food sealing is extremely important for the Keep the quality and freshness of food, and at present, the food fresh keeping plastic case of in the market is big
It is to be sealed by machine mostly, is eaten once opening packing box, sealing can not be just realized again, so businessman typically can also eat
Instant bagged is indicated on product packing box, how to design one can manually implemented self sealss packing box, extend the preservation of instant food
It is time limit, often to be solved in real life.
In a kind of plastic casing circular lid interference insertion circular base for self sealss that the utility model refers to, pass through plain seal side
Self sealss twice, good sealing effect are realized with being bonded for recessed joint portion, while is processed in circular lid with flat joint portion, recessed sealing strip
There is hand to lift side, uncap easily, it is very useful in daily life.
Utility model content
Weak point present in regarding to the issue above, the utility model provide a kind of plastic casing of self sealss.
To achieve the above object, the utility model provides a kind of plastic casing of self sealss, including：
Circular lid, it is in level side that plain seal side and recessed sealing strip, the plain seal side are processed on the circumference of the circular lid
To the recessed sealing strip is U-shaped structure；
Circular base, flat joint portion and recessed joint portion is processed on the circumference of the circular base, the flat joint portion is in level side
Matched to the plain seal side, the recessed joint portion and the identical size of shape of the recessed sealing strip are less than the recessed sealing
Side, the recessed joint portion inner side is guide part, and shrinkage joint is machined with the circumference of the guide part；
The diameter of the circular lid is more than the circular base, and the circular lid interference is embedded in the circular base, passes through institute
State plain seal side and realize self sealss twice with being bonded for the recessed joint portion with the flat joint portion, the recessed sealing strip.
Hand, which is also processed, as further improvement of the utility model, on the circumference of the circular lid lifts side.
As further improvement of the utility model, by reinforcement transition on the inside of the guide part.
The beneficial effects of the utility model are：
In circular lid interference insertion circular base, pass through plain seal side and flat joint portion, the recessed sealing strip and patch of recessed joint portion
Close and realize self sealss twice, good sealing effect, while hand is machined with circular lid and lifts side, uncap easily, it is non-in daily life

Embodiment
As illustrated, a kind of plastic casing of self sealss described in the utility model embodiment, including：As shown in Figure 1 and Figure 2,
Plain seal side 12 and recessed sealing strip 13 are processed on the circumference of circular lid 1, in horizontal direction, recessed sealing strip 13 is U on plain seal side 12
Shape structure, hand is also processed on the circumference of circular lid 1 and lifts side 11；As shown in Figure 3, Figure 4, reef knot is processed on the circumference of circular base 2 to close
Portion 21 and recessed joint portion 22, flat joint portion 21 match with plain seal side 12 in horizontal direction, recessed joint portion 22 and recessed sealing strip 13
Shape size of coincideing be less than recessed sealing strip 13, it is guide part 23 that recessed joint portion 22 is interior, and receipts are machined with the circumference of guide part 23
Contracting seam 232, guide part 23 is interior by the transition of reinforcement 231；As shown in Figure 5, Figure 6, the diameter of circular lid 1 is more than circular base 2, circular
In the interference of lid 1 insertion circular base 2, it is bonded by plain seal side 12 with flat joint portion 21, recessed sealing strip 13 with recessed joint portion 22
Realize self sealss twice.
In circular lid interference insertion circular base, pass through plain seal side and flat joint portion, the recessed sealing strip and patch of recessed joint portion
Close and realize self sealss twice, good sealing effect, while hand is machined with circular lid and lifts side, uncap easily, it is non-in daily life
Chang Shiyong.
When specifically used, the utility model is understood for convenience, is described with reference to accompanying drawing；
Because the diameter of circular lid is more than circular base, circular lid is pressed into circular base manually, circular lid and circular base mistake
Fit be full of together, realizes self sealss, it is specific as follows：Recessed sealing strip is bonded under the guide effect of guide part with recessed joint portion,
Plain seal side is bonded the sealing function realized twice with flat joint portion simultaneously, and guide part processing shrinkage joint makes guide part have one
Determine the contraction release stress of degree；When needing to open plastic casing, side is lifted by the hand of circular lid and lifted outward, under external force,
Circular lid, circular base disengage.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
