Technical Field
The invention relates to an improved invention of a paper container, in particular to an improved invention of a cup-shaped paper cover.
Background
In the prior art, the paper cover is widely applied, and compared with hot drinks, the paper cover has higher requirements, and when the hot drinks shake, the paper cover needs to be prevented from being detached and the hot drinks need to be leaked, and the hot drinks are allowed to breathe. Although the existing paper cover has a structure for buckling and sealing with a container port, the connecting structure between the cover surface of the paper cover and the paper ring is characterized in that an inner folded edge is arranged at the upper end of the paper ring and is adhered with the cover surface, so that the overall structure strength is low, the stability is poor, and the sealing effect is greatly reduced.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the prior art and providing the cup-shaped paper cover with stable structure and good sealing performance.
In order to solve the technical problems, the invention is realized by adopting the following technical scheme: this kind of cup type paper lid, including paper circle and capping, its characterized in that: the upper end of the paper ring is provided with a reverse folding part positioned at the inner side, the periphery of the cover surface is provided with an upper folding part, and the upper folding part is adhered between the reverse folding part and the paper ring in a spinning way; the cover surface is provided with a cylindrical sunken part, an annular clamping groove is formed between the side wall of the sunken part and the paper ring, and the annular clamping groove is matched with the container rolling opening.
The paper ring is also provided with a buckling position which is arranged at the lower side of the annular clamping groove and is in limit fit with the rolling opening of the container.
The buckling position is formed by inwards sinking the paper ring.
The bottom surface of the sinking part is of a double-sheet structure, the double sheets are arranged at intervals, and ventilation holes distributed in a staggered mode are formed in the double sheets.
The double sheets comprise an inner sheet and an outer sheet, and bosses positioned between the double sheets are arranged on the inner sheet or the outer sheet.
The bottom surface of the sinking part is provided with a direct drinking mouth adjacent to the edge.
The paper ring has a taper.
The lower end of the paper ring is provided with an outer curled edge.
The improved cup-shaped paper cover has the beneficial effects that the paper ring and the cover surface are connected by adopting the reverse folding part and the upper folding part in a knurling way, namely, a boss is formed above the paper cover, so that the whole paper cover is supported, the structural strength and the stability are effectively enhanced, and the sealing effect is ensured; in addition, the double-piece structure is provided with the ventilation holes, so that the ventilation of hot drinks is facilitated, and the overflow of the hot drinks through the ventilation holes is prevented.

Detailed Description
The drawings illustrate the structure of the present invention, and details thereof are further described below with reference to the drawings. In the embodiment, the cup-shaped paper cover comprises a paper ring 1 and a cover surface 2, wherein the upper end of the paper ring 1 is provided with a folded part 11 positioned at the inner side, the periphery of the cover surface 2 is provided with an folded part 21, the folded part 21 is adhered between the folded part 11 and the paper ring 1 by adopting a knurling process in a spinning way, so that the cover surface 2 and the paper ring 1 are stably connected, a boss is formed above the cup-shaped paper cover, and the cup-shaped paper cover is integrally supported, so that the structural strength is effectively enhanced; the cover surface 2 is provided with a cylindrical sunken part 3, the cylindrical sunken part 3 is formed by compression molding, an annular clamping groove 4 is formed between the side wall of the sunken part 3 and the paper ring 1, the annular clamping groove 4 is matched with a container rolling opening, namely, the corresponding container rolling opening is buckled in the annular clamping groove 4 in a matching manner and forms a seal with the annular clamping groove 4, and the seal surface can be formed by laminating between the curled edge of the container rolling opening and the annular clamping groove 4 or between the inner wall of the container and the annular clamping groove 4.
As a further improved specific embodiment, the paper ring 1 is further provided with a buckling position 5, the buckling position 5 is arranged at the lower side of the annular clamping groove 4 and is in limit fit with the container rolling opening, and the specific buckling position 5 limits the lower side of the container rolling opening; preferably, the buckling position 5 is formed by inwards recessing the paper ring 1. The buckling position 5 is used for assisting the annular clamping groove 4 to limit and seal the container rolling opening.
As a further improved specific implementation manner, the bottom surface of the sinking part 3 is of a double-sheet 6 structure, the double sheets are arranged at intervals, the double sheets are provided with ventilation holes 7 distributed in a staggered manner, the ventilation holes 7 are arranged to facilitate ventilation of hot drinks, and the dislocation distribution of the ventilation holes 7 can prevent the hot drinks from shaking and overflow through the ventilation holes 7.
As a further improved specific embodiment, the double sheets 6 include an inner sheet and an outer sheet, and the inner sheet or the outer sheet is provided with a boss 61 located between the double sheets, the boss 61 supports the double sheets 6, so that a space is formed between the double sheets 6, and ventilation effect of the ventilation holes 7 is further ensured. Wherein, the inner sheet is preferably a bottom body part of the depressed part of the cover surface, the outer sheet is an external patch, the boss 61 is arranged on the outer sheet, and 4 bosses are uniformly arranged on the outer sheet in a ring.
