Description
Technical Field
The utility model relates to the technical field of lunch box paper covers, in particular to a degradable leakage-proof paper cover.
Background
With the promotion of social economy and the attention to the concept of environmental protection, the market gradually replaces the original plastic lunch box, especially the paper lunch box, with the disposable lunch box made of degradable materials. But the ubiquitous case is: the situation that the sealing performance is poor is often existed when the paper cover is covered on the paper lunch box.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the degradable leakage-proof paper cover which aims at better overall sealing effect and is not easy to leak is provided so as to overcome the technical defects.
The specific technical scheme is as follows:
the utility model provides a degradable leak protection paper lid, includes the main part by paper pulp integrated into one piece, and the main part is whole to be circular lid column structure, and the outer edge of main part is turned over to the enstrophe and is formed with annular turn-ups, and the turn-ups of annular edge further turns over to the enstrophe and is formed with annular surrounding edge, and the interior bottom annular uplift of main part has an annular flange to it has the annular groove to constitute between annular flange and annular turn-ups, and the embedded sealing washer of being made by the PLA material that is equipped with of annular groove.
Preferably, the inner bottom surface of the main body is also provided with an annular retaining ring protruding in the inner side direction of the annular retaining edge.
Preferably, the upper bottom surface of the main body is further recessed downward to form a circular groove and the inner bottom surface of the main body is raised to form a circular protrusion.
Preferably, the circular groove is also provided with an arc-shaped paper sheet.
The beneficial effects of the above technical scheme are that:
the degradable leak-proof paper cover comprises a main body, wherein an annular flange, an annular surrounding edge, an annular retaining edge and an annular groove are formed in the main body, a sealing ring is embedded in the annular groove, the upper edge of a bowl body matched with the annular flange, the annular surrounding edge, the annular retaining edge and the sealing ring are clamped together, the overall sealing effect is good, and the problem of leakage is not easy to generate.

Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the utility model easy to understand, the following embodiments are specifically described with reference to the attached drawings. And defines the direction from the top to the bottom as viewed from the paper in fig. 3 as the direction from the top to the bottom in this embodiment, and the direction from the outside of the main body to the center of the main body as viewed from the paper is the direction from the outside to the inside.
Referring to fig. 1 to 3, the degradable leakproof paper cap provided by this embodiment includes a main body 1 integrally formed by paper pulp, the main body 1 is integrally a circular cap-shaped structure, an annular flange 2 is formed by folding the outer edge of the main body 1 inward, an annular surrounding edge 3 is formed by further folding the edge of the annular flange 2 inward, an annular rib 4 is formed by annularly protruding the inner bottom surface 9 of the main body 1, an annular groove 6 is formed between the annular rib 4 and the annular flange 2, and a sealing ring (not shown in the figure) made of PLA (polylactic acid) is embedded in the annular groove 6.
In the specific application, the main body 1 of the degradable leakproof paper cover is assembled on the bowl body, the annular upper edge of the bowl body is embedded into the annular groove 6 and is abutted against the sealing ring, and the annular surrounding edge 3 inwards coats the annular upper edge of the bowl body. Based on above-mentioned technical scheme, degradable leak protection paper lid includes main part 1 to constitute on main part 1 and have annular turn-ups 2, annular surrounding edge 3, annular flange 4 and ring channel 6, 6 embedded sealing washers that are equipped with of ring channel, by the common bowl body upper edge that the centre gripping matches of annular turn-ups 2, annular surrounding edge 3, annular flange 4 and sealing washer, the whole sealed effect preferred is difficult for producing the problem of revealing.
In a preferred embodiment, the inner bottom surface 9 of the main body 1 is further raised with an annular rib 5 in the direction of the inner side of the annular rib 4, so as to enhance the reliability of the annular rib 4. Further, the upper bottom surface 10 of the main body 1 is formed with a circular groove 11 recessed downward and a circular protrusion 8 formed protruding from the inner bottom surface 9 of the main body 1. Further, the circular groove 11 is provided with an arc-shaped paper sheet 7 as a holding handle to assist the lifting when the paper cover main body 1 needs to be separated from the bowl body.
The foregoing is merely a preferred embodiment of the utility model, which is intended to be illustrative and not limiting. It will be understood by those skilled in the art that various changes, modifications and equivalents may be made therein without departing from the spirit and scope of the utility model as defined in the appended claims.
