Therefore, how leakproofness is improved, achievees the purpose that leakproof is anti-overflow, it is urgently to be resolved becomes those skilled in the art
Technical problem.
Utility model content
In view of this, the present invention provides a kind of anti-overflow strip of paper used for sealing and containers, improve leakproofness, to reach leakproof
Anti-overflow purpose.
In order to achieve the above object, the utility model provides the following technical solutions:
A kind of anti-overflow strip of paper used for sealing, which is characterized in that the anti-overflow strip of paper used for sealing is the film with degree of sticking together and ductility, is being sealed
Under state, the film can be closely adhered to container edge after the stretch and wait for sealing part.
Preferably, in above-mentioned anti-overflow strip of paper used for sealing, the anti-overflow strip of paper used for sealing is by least one of PE, PVDC and PVC material group
At anti-overflow strip of paper used for sealing.
Preferably, in above-mentioned anti-overflow strip of paper used for sealing, the length of the anti-overflow strip of paper used for sealing is that the container edge waits for sealing part perimeter
1 times -2 times.
Preferably, in above-mentioned anti-overflow strip of paper used for sealing, under non-tight state, one end of the anti-overflow strip of paper used for sealing passes through stickup, heat
Perhaps welding mode is connect with the container and the other end is free end.
A kind of container, including above-mentioned anti-overflow strip of paper used for sealing.
Preferably, in said vesse, the container includes vessel and container cover, and the edge of the vessel waits for
Sealing part is provided with protrusion, the container cover be provided with recess portion on the protrusion relative position, the protrusion with it is described recessed
Portion is fitted close for sealing.
Preferably, in said vesse, the container is lunch box.
According to the above technical scheme it is found that a kind of anti-overflow strip of paper used for sealing provided by the embodiment of the utility model, on container latching
Afterwards, anti-overflow strip of paper used for sealing is redrawn, using the tack of anti-overflow strip of paper used for sealing, in sealed states, oriented film can tight adhesion
Sealing part is waited in container edge, to improve sealing effect, achievees the purpose that leakproof is anti-overflow.This programme also provides a kind of with upper
State the container of anti-overflow strip of paper used for sealing.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is the embodiments of the present invention, for those of ordinary skill in the art, without creative efforts, also
Other attached drawings can be obtained according to the attached drawing of offer.
Fig. 1 is the structural schematic diagram of container provided by the embodiment of the utility model；
Fig. 2 is the partial structural diagram of container edge position provided by the embodiment of the utility model；
Fig. 3 is the partial structural diagram that container edge position provided by the embodiment of the utility model connects anti-overflow strip of paper used for sealing.
In the figure, it is marked as
1, container；2, anti-overflow strip of paper used for sealing.
Specific embodiment
In order to make it easy to understand, the utility model will be further described with reference to the accompanying drawing.
Referring to figures 1-3, a kind of anti-overflow strip of paper used for sealing provided by the embodiment of the utility model, anti-overflow strip of paper used for sealing 2 are with tack
Film, in sealed states, film can be closely adhered to 1 edge of container after the stretch and wait for sealing part.With tack
Film also has degree of sticking together and ductility.
It should be noted that anti-overflow strip of paper used for sealing does not show tack under normal state, after Tensile, anti-overflow strip of paper used for sealing is in
Existing tack, anti-overflow strip of paper used for sealing length is accordingly elongated at this time, and anti-overflow strip of paper used for sealing is constant with container closure link position.The ductility of film
Height can bear certain pulling force.And during stretching, film can release stickiness, and fitting is adhered on container 1.
A kind of anti-overflow strip of paper used for sealing provided by the embodiment of the utility model, on container latching after, redraw anti-overflow strip of paper used for sealing, utilize
The tack of anti-overflow strip of paper used for sealing, in sealed states, oriented film can be closely adhered to 1 edge of container and wait for sealing part, from
And sealing effect is improved, achieve the purpose that leakproof is anti-overflow.
In a particular embodiment, anti-overflow strip of paper used for sealing 2 is the anti-overflow strip of paper used for sealing being made of at least one of PE, PVDC and PVC material.
Further include sticky aid master batches and resin in anti-overflow strip of paper used for sealing, is formed by blended melting.
The tack that main points rely on material self-sealed article itself is sealed it should be further noted that realizing, and tack, lead to
The excitation of overstretching self-sealed article.PE, PVDC and PVC have tack it is characterized in that degree of sticking together is high, ductility is high, this " viscosity "
It is different from the viscosity of adhesive, is in plastic processes, with the sticky aid master batches such as PIB or the shape of liquid being directly injected into
Formula, with resin alloy melt molding.Because of the incompatibility of PIB and resin, PIB meeting migration precipitation makes its generation to film surface
Viscosity.Therefore, object or vessel surface can be tightly adhered to.For the tack effect convenient for comprehensive test preservative film, industry
" shearing peel strength " is generallyd use to characterize, and true by standard GB/T/T10457 " food plastics self-adhering plastic wrap "
Underlying parameter requirement and test method are determined.According to the regulation of 2009 editions standards, PE, PVC, PVDC or multi-layer co-extruded preservative film
Tack (shearing peel strength) answer >=0.5N/cm2。
In preferred embodiment, for the leakproofness of full protection sealing part, the length of anti-overflow strip of paper used for sealing 2 is 1 side of container
Along 1 times -2 times to sealing part perimeter.
It is further preferred that under non-tight state, one end of anti-overflow strip of paper used for sealing 2 by stickup, thermal capacitance or welding mode with
The connection of container 1 and the other end are free end.For anti-overflow strip of paper used for sealing on container cover outermost edge, connection type is chosen as stickup, heat
Perhaps welding etc..
In addition, this programme also provides a kind of container, including anti-overflow strip of paper used for sealing 2, which is in above-mentioned specific embodiment
Anti-overflow strip of paper used for sealing, therefore, the container with the anti-overflow strip of paper used for sealing equally has the beneficial effect of anti-overflow strip of paper used for sealing, and details are not described herein.
In order to further enhance the leakproofness of container, container 1 includes vessel and container cover, and the edge of vessel waits for
Sealing part is provided with protrusion, container cover with recess portion is provided on the relative position of protrusion, protrusion is fitted close with recess portion for close
Envelope.
Optionally, container 1 is lunch box, such as disposable lunch box.
On the one hand the utility model can reduce the loss of businessman, when container is toppled over without pinching sealing part, avoid container
Four occur when middle liquid pouring to dissipate, the another further aspect design structure is low in cost, and processing technology is simple, and easy to operate, effect is aobvious
It writes.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.A variety of modifications of embodiment will be readily apparent to those skilled in the art, it is as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present utility model.Therefore, originally
