[ detailed description ] embodiments
The following examples are further illustrative and supplementary to the present invention and do not limit the present invention in any way.
As shown in fig. 1 to 9, a sealing cover for a plastic barrel comprises an upper cover 10 and an inner cover 20, wherein the upper cover 10 is sleeved on the top of the inner cover 20, the upper cover 10 comprises a cover body 11, a clamping column 12 is arranged at the bottom of the cover body 11, an anti-theft strip 13 is embedded in the middle of the cover body 11, one end of the anti-theft strip 13 is connected with the clamping column 12, two sides of the anti-theft strip 13 are connected with the cover body 11 through a tearing strip 14, and one end of the cover body 11 is further provided with a pulling strip 15;
the inner cover 20 comprises an end cover 21, an accommodating cavity 22 is formed in the middle of the end cover 21, the accommodating cavity 22 is formed by sequentially connecting a protruding portion 23 and a recessed portion 24, the clamping column 12 is clamped in the accommodating cavity 22, and when the sealing cover needs to be opened, the pulling strip 15 is pulled, so that the tearing strip 14 is broken, the clamping column 12 is pulled out of the inner cover 20, and the inner cover 20 is rotated to realize the unsealing process.
A sealing cover for a plastic barrel is mainly used for sealing liquid in the plastic barrel by matching an upper cover 10 and an inner cover 20, preventing the liquid in the plastic barrel from volatilizing, avoiding the change of the concentration of the liquid in the barrel caused by the moisture in the air entering the barrel, wherein the specific upper cover 10 is sleeved on the top of the inner cover 20, the upper cover 10 comprises a cover body 11, a clamping column 12 is arranged at the bottom of the cover body 11, an anti-theft strip 13 is embedded in the middle of the cover body 11, one end of the anti-theft strip 13 is connected with the clamping column 12, two sides of the anti-theft strip 13 are connected with the cover body 11 through tearing belts 14, one end of the cover body 11 is also provided with a pulling strip 15, the inner cover 20 comprises an end cover 21, the middle part of the end cover 21 is provided with an accommodating cavity 22, the accommodating cavity 22 is formed by sequentially connecting a convex part 23 and a concave part 24, and the clamping column 12 is clamped in the accommodating cavity 22.
To be more specific, when the plastic barrel is not required to be opened, the inner cap 20 is screwed on the top of the plastic barrel, and then the clamping column 12 of the upper cap 10 is pressed into the accommodating cavity 22 on the top of the inner cap 20, at this time, the clamping column 12 of the upper cap 10 is clamped below the protrusion 23, so that the sealing process of the upper cap 10 and the inner cap 20 is realized, external moisture is prevented from entering through the inner cap 20 (the top of the inner cap 20 is provided with a vent hole with a small aperture, which prevents the air pressure in the barrel from being too high), and the internal air can be prevented from leaking to the outside, on the other hand, the anti-theft strip 13 and the tear strip 14 arranged on the top of the upper cap 10 are not loosened when the sealing cap is not opened, so that no gap is formed, the external air cannot enter the inner cap 20, and whether the raw materials in the plastic barrel are stolen or not can be judged by observing the anti-theft strip 13 and the tear strip 14 in the upper cap 10 (if the anti-theft strip 13 and the tear strip 14 are used, both the tear strip 14 and the tamper strip 13 will loosen).
When the raw material in the plastic barrel needs to be used, firstly, the pulling strip 15 needs to be lifted upwards, the pulling strip 15 can drive the cover body 11 to move upwards, because one end of the anti-theft strip 13 is connected with the clamping column 12, the clamping column 12 is clamped on the inner cover 20 and cannot move along with the lifting of the upper cover 10, one end of the anti-theft strip 13 cannot move, but the other end of the anti-theft strip 13 is connected with the cover body 11, and because the two sides of the anti-theft strip 13 are connected with the cover body 11 through the tearing bands 14, the tearing bands 14 are thin and can be broken after being pulled, so that the other end of the anti-theft strip 13 rises along with the lifting of the cover body 11, all the tearing bands 14 on the two sides of the anti-theft strip 13 are broken, thereby completing the primary unsealing process, at this time, one end of the anti-theft strip 13 is connected with the cover body 11, the other end is connected with the clamping column 12, subsequently, the upper cover 10 is rotated, so that one end of the anti-theft strip 13 connected with the clamping column 12 is exposed in the recessed part 24 (when the upper cover 10 is subsequently pulled out, need place the one end of theftproof strip 13 in depressed part 24, when follow-up exerting oneself and pulling upper cover 10, theftproof strip 13 can take place the type and become, if theftproof strip 13 is the card in bulge 23, then it is difficult not to take along card post 12 to extract), then lift lid 11 hard, lid 11 can drive card post 12 and extract from holding chamber 22 to upper cover 10 has been taken out.
After taking out upper cover 10, only need rotate the top of inner cup 20 for threaded connection portion 40 of inner cup 20 bottom is not hard up, extracts it again and can realize the deblocking process of whole sealed lid, thereby can use the raw materials in the plastic drum.
According to the utility model, the upper cover 10 and the inner cover 20 are arranged, so that the sealing effect of the plastic barrel is realized, the situations of air leakage and liquid leakage cannot occur, the sealing cover is unsealed through the matched pulling of the anti-theft strip 13, the pulling strip 15 and the tearing strip 14, so that the disassembly is simple and convenient, and whether the sealing cover is stolen or loosened can be judged by observing whether the tearing strip 14 is complete or not.
