Abstract
The present invention relates to a kind of seam formula thermoforming plastic lids, including pearl and sealant, the pearl fixes band both ends by strip and forms entirety by the way that hot pressing is affixed, the pearl is provided with support convex edge in its inner ring, the sealing is placed on the support convex edge either above or below, and the sealant forms whole cover with the support convex edge by heat seal.The present invention changes the stamping forming manufacturing method of conventional plastic lid, plastic lid is divided into the pearl and sealant for being connected and being formed with both ends by strip fixation, entire plastic lid integral thickness is uniform, sound construction.During producing simultaneously, the process that plastic sheet cuts into strip made-up belt also greatly reduces the generations of leftover pieces.
Description
Technical field
The present invention relates to plastic lid fields, have referred specifically to a kind of seam formula thermoforming plastic lid.
Background technology
Disposable plastic cup cover, bowl cover and cutlery box lid are fast service restaurant industry or even the widely applied product of daily household, are used
It measures huge, the containers such as cup, bowl can be helped to be sealed, prevent the liquid in container from spilling.Simultaneously also have it is nontoxic, be no different
The advantages that taste.
The production of disposable plastic cup cover currently on the market, bowl cover and cutlery box lid product, is occupied the majority with punch forming,
Generally using film-form plastics, punching press is carried out by mold after heating, corresponding pattern and shape is formed, is finally cut into institute
The part needed.Although such method is simple, since punching press acts at the punching press of plastic lid, significantly thinning, shadow at punching press
Even there is phenomena such as damaged in the closely sealed performance rung to lid.Meanwhile a large amount of leftover pieces can also be generated using the method for punching press,
Cause certain waste.
Material can be saved and prevent from breaking at punching press by designing one kind for above-mentioned problem of the existing technology
The plastic lid of damage is the purpose that the present invention studies.
Invention content
In view of the above-mentioned problems of the prior art, the invention reside in a kind of seam formula thermoforming plastic lid is provided, it can
Effectively solve the above-mentioned problems of the prior art.
The technical scheme is that：
A kind of seam formula thermoforming plastic lid, including pearl and sealant, the pearl fixes band both ends by strip and passes through heat
Pressing connects to form entirety, and the pearl is provided with support convex edge in its inner ring, and the sealing is placed on above the support convex edge
Or lower section, the sealant form whole cover with the support convex edge by heat seal.
The sealant is the one kind of film or lamination cardboard either in plank or sheet material.
The pearl be rectangular, round or other regular geometric shapes in one kind.
Advantages of the present invention：
The present invention changes the stamping forming manufacturing method of conventional plastic lid, and plastic lid is divided into and fixes band both ends company by strip
The pearl and sealant to be formed are connect, entire plastic lid integral thickness is uniform, sound construction.During producing simultaneously, plastic sheet
The process that material cuts into strip made-up belt also greatly reduces the generations of leftover pieces.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
It is in order to facilitate the understanding of those skilled in the art, existing that embodiment combination attached drawing is further detailed to the structure work of the present invention
Thin description：
With reference to figure 1, a kind of seam formula thermoforming plastic lid, including pearl 1 and sealant 3, the pearl 1 fixes band by strip
Both ends form entirety by the way that hot pressing is affixed, and the pearl 1 is provided with support convex edge 2 in its inner ring, and the sealant 3 is placed in described
2 either above or below of convex edge is supported, the sealant 3 forms whole cover with the support convex edge 2 by heat seal.
The sealant 3 is the one kind of film or lamination cardboard either in plank or sheet material.
The pearl 1 be rectangular, round or other regular geometric shapes in one kind.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification should all belong to the covering scope of the present invention.
