Description
Technical Field
The invention relates to the technical field of paper cups, in particular to a structure of a paper cover of a scald-proof and heat-insulating paper cup.
Background
The paper cup is a container which is convenient to use and wide in application, and is particularly used for containing liquid such as water, coffee, milk and the like or occasions where materials such as instant noodles, instant powder and the like need to be mixed or mixed.
Traditional paper cup structure, as chinese patent application No.: 201720201523.1A paper cup comprises a cup body and a cup bottom, wherein the upper edge of the cup body is provided with an upper turned edge folded outside the cup, the side wall of the cup body is formed by connecting and fixing a single paper wall end to end, the paper cup is connected end to form a cup body joint part, the edge of the cup bottom is bent downwards to form an edge downward folding area, the edge downward folding area is wrapped and adhered by an inward folding area wrapped inwards at the bottom of the side wall of the cup body to form a cavity with an upward opening, and a pressing line is arranged outside the inward folding area to increase the bonding strength between the cup bottom and the side wall of the cup body.
The existing paper cover covers the paper cup mainly in two types, the first type is an inner clamping type, namely, most of the paper cover is embedded into the paper cup, and then the outer surface of the paper cover is used for clamping an upper curled edge on the paper cup; the second type is an outer clamping type, namely, a paper cover is sleeved outside the paper cup, and then the inner surface of the paper cover is utilized to clamp the upper curled edge of the paper cup, so that the paper cup is connected with the paper cover in a clamping manner.
However, whether the paper cup and the paper cover are connected in an inner clamping type or an outer clamping type, when carrying hot drinks, because of the expansion of the air in the paper cup, the inner surface of the paper cover generates upward thrust to act on the upper curled edge, so that the leakage phenomenon is generated at the covered part of the paper cup and the paper cover, and the heat insulation effect of the paper cup is poor, if the inner-clamping type paper cup and the paper cover are carried, the holding area of the paper cover is small, and the paper cover can be deformed when being held and extracted, so that the clamping effect of the paper cup and the paper cover is poor, the paper cup and the paper cover are separated, the heat is transferred to the hand when the paper cup is held and closed, and scalding is caused, when the paper cup and the paper cover are carried, when the paper cover is held, the deformation of the paper cover causes the separation of the joint area of the paper cover and the paper cup, the leakage phenomenon of the joint area of the paper cup and the paper cover is increased, and the scald is easily caused when the paper cup is held.
Disclosure of Invention
Therefore, aiming at the problems, the invention provides a structure of a paper cover of a scald-proof and heat-insulating paper cup, which mainly solves the problem that the paper cover is easy to separate from a hot drink carried by the paper cup to cause serious scald in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:
the structure of the paper cup paper cover capable of preventing scald and insulating heat comprises a paper cup and a paper cover arranged at the cup opening of the paper cup in a covering mode, wherein the upper edge of the paper cup is outwards and downwards rolled to form an upper turned edge, a first polylactic acid laminating layer is compounded on the inner surface of the paper cup, the paper cover comprises a paper cover body and a cover plate which are in a conical ring shape, a second polylactic acid laminating layer is compounded on the inner surface of the cover body, a third polylactic acid laminating layer is compounded on the lower surface of the cover plate, the upper edge of the cover body is inwards and downwards rolled to form an inner turned edge, the edge of the upper surface of the cover plate is connected with the inner turned edge in an adhesive mode, a drinking opening is formed in the cover plate, a top placing adhesive line is inwards concave on the outer surface of the cover body in a surrounding mode, the paper cover is covered on the paper cup, the upper turned edge is embedded between the top placing adhesive line and the cover plate, and the first polylactic acid laminating layer, when the temperature of the liquid or solid-liquid mixture contained in the paper cup is 60-100 ℃, the contact area of the first polylactic acid film layer at the upper end of the upper curled edge and the third polylactic acid film layer on the cover plate is heated by heat to generate molecule recombination and is combined together, the lower edge of the cover body is curled outwards and upwards to form an outer curled edge, the cover body is used for being held by a hand and closed on the outer curled edge to avoid the paper cup from falling off, and the heat insulation and scald prevention effects are achieved.
Further, when the paper cover is covered on the paper cup, the upper end of the upper turned edge is flattened to form a first connecting surface which is annular in plane, a first polylactic acid laminating layer on the first connecting surface is in press fit with a third polylactic acid laminating layer on the cover plate, the outer end of the upper turned edge is flattened to form a second connecting surface which is annular in plane, and the first polylactic acid laminating layer on the second connecting surface is in press fit with the second polylactic acid laminating layer on the cover body.
By adopting the technical scheme, the invention has the beneficial effects that: the structure of the scald-proof and heat-insulation paper cup and paper cover is characterized in that an upper curled edge of a paper cup is embedded into a space formed by a cover body, a cover plate and a top placing bonding line, the hardness of the annular paper cup is higher, when the annular paper cup is embedded into the space, the upper curled edge is extruded to deform so as to press in, the lower end of the pressed upper curled edge is abutted against the top placing bonding line, the upper end and the outer end of the upper curled edge are abutted against the lower surface of the cover plate and the inner surface of the cover body respectively, double bonding connection is formed, leakage is avoided, the first polylactic acid leaching film layer, the second polylactic acid leaching film layer and the third polylactic acid leaching film layer are bonded, the surface smoothness is high, the contact surface bonding effect is better, the sealing performance is improved, when the paper cup is extracted, the space formed by the cover body, the cover plate and the top placing bonding line is extruded and reduced, and the extrusion force of the curled edge, the cover body and the cover, the sealing performance is further improved, and meanwhile, the distance between the cover body and the cup body is increased while the structure of the cover body is relatively stable due to the design of the outer curled edge, so that the anti-scalding effect is achieved; when the temperature is in 60 ℃ -100 ℃, first polylactic acid drenches rete and third polylactic acid drenches rete contact area, its inside molecule that forms softens and combines again, make the first polylactic acid drenches rete of the upper end of last turn-up and the third polylactic acid drenches the rete bonding together on the apron, play scald preventing's effect, compare with the joint cooperation of paper cup and paper lid in the past, it passes through the higher liquid of splendid attire temperature or solid-liquid mixture, make mutual bonding between the polylactic acid drenches the rete, form sealed splendid attire space, prevent that liquid from oozing, very big play the guard action, prevent the scald.
