The service life of pack.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of degradable packing bag.
The utility model achieves the above object through the following technical schemes:
A kind of degradable packing bag, including the bag body made of degradative plastics；
Self-sealed article is provided at the sack of the bag body, the self-sealed article includes the recessed strip of paper used for sealing being mutually matched and convex envelope
Item, the recessed strip of paper used for sealing and the convex strip of paper used for sealing are connected to the two sides in sack, recessed by the way that the bar shaped fin of convex strip of paper used for sealing to be stuck in
In the strip groove of strip of paper used for sealing, sack can be sealed；
The width of the notch of the strip groove to slot bottom is first to reduce, increase afterwards, the minimum widith of the strip groove
Less than the high-end width of the bar shaped fin, and it is greater than the low side width of the bar shaped fin；
The slot bottom of the strip groove is connected with elastic packing locking bar, when the bar shaped fin is stuck in the strip groove
When middle, the elastic packing locking bar is squeezed and deforms, to realize that the bar shaped fin and strip groove sealing block
Tightly.
Preferably, the bar shaped fin of the strip groove of the recessed strip of paper used for sealing, the convex strip of paper used for sealing has multiple, the bar shaped is recessed
Slot and the bar shaped fin correspond.
Preferably, the quantity of the recessed strip of paper used for sealing and the convex strip of paper used for sealing is three.
Compared with prior art, the utility model has the following beneficial effects:
It is provided with self-sealed article at sack, is made of recessed strip of paper used for sealing and convex strip of paper used for sealing, by the way that recessed strip of paper used for sealing is engaged with convex strip of paper used for sealing,
It can be realized the sealing of the sack of degradable packing bag, gauffer will not be generated, be able to extend the service life of degradable packing bag,
Elastic packing locking bar is provided in the strip groove of recessed strip of paper used for sealing, when bar shaped fin is stuck in strip groove, elastic packing
Locking bar is squeezed and deforms, and plays the role of self-locking seal to the clamping structure of bar shaped fin and strip groove, so that bar shaped
Fin can fit closely in strip groove, it is ensured that the high leakproofness of sack.

In above-mentioned attached drawing, the corresponding component names of appended drawing reference are as follows:
1- bag body, 2- self-sealed article, the convex strip of paper used for sealing of 21-, the recessed strip of paper used for sealing of 22-, 211- bar shaped fin, 221- strip groove, 222- bullet
Property sealing locking bar.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
In conjunction with shown in Fig. 1, Fig. 2 and Fig. 3, the utility model includes bag body 1 made of degradative plastics；
Self-sealed article 2 is provided at the sack of bag body 1, self-sealed article 2 includes the recessed strip of paper used for sealing 22 and convex strip of paper used for sealing 21 being mutually matched,
Recessed strip of paper used for sealing 22 and convex strip of paper used for sealing 21 are connected to the two sides in sack, by the way that the bar shaped fin 211 of convex strip of paper used for sealing 21 is stuck in recessed envelope
In the strip groove 221 of item 22, sack can be sealed；
The width of the notch of strip groove 221 to slot bottom is first to reduce, increase afterwards, and the minimum widith of strip groove 221 is small
In the high-end width of bar shaped fin 211, and it is greater than the low side width of bar shaped fin 211, the size design, so that bar shaped fin
211 can be caught in inside strip groove 221, specific as shown in Figure 2；
The slot bottom of strip groove 221 is connected with elastic packing locking bar 222, when bar shaped fin 211 is stuck in strip groove 221
When middle (position is as shown in Figure 2), elastic packing locking bar 222 is squeezed and deforms, to realize that bar shaped fin 211 and bar shaped are recessed
Slot 221 seals clamping.
The working principle of the utility model is as follows:
When needing to seal the sack of bag body 1, by the corresponding bar shaped for being pressed into recessed strip of paper used for sealing 22 of the bar shaped fin 211 of convex strip of paper used for sealing 21
In groove 221；
The notch of strip groove 221 is to the width design of slot bottom and the high-end width and low side width of bar shaped fin 211
Design makes so that being formed at the notch of strip groove 221 can guide bar shaped fin 211 to be caught in the inclined-plane in strip groove 221
It obtains bar shaped fin 211 and is pressed into easy to operate in strip groove 221, easy contraposition；
When bar shaped fin 211 is stuck in strip groove 221, elastic packing locking bar 222 is squeezed and deforms, to not
After pressing to bar shaped fin 211, elastic packing locking bar 222 plays the clamping structure of bar shaped fin 211 and strip groove 221
Self-locking seal effect, so that bar shaped fin 211 can fit closely in strip groove 221, it is ensured that the high sealing of sack
Property.
Preferably, the bar shaped fin 211 of the strip groove 221 of recessed strip of paper used for sealing 22, convex strip of paper used for sealing 21 has multiple, strip groove
221 correspond with bar shaped fin 211, which can further improve self-sealed article 2 to the sealing performance of sack.
Preferably, the quantity of recessed strip of paper used for sealing 22 and convex strip of paper used for sealing 21 is three, in this way the case where guaranteeing high sealing performance
Under, appearance is also more beautiful, and convenient for being laid out in bag body 1.
According to above embodiment, the utility model can be realized well.It is worth noting that being set based on above structure
Under the premise of meter, to solve same technical problem, even if made on the utility model it is some without substantive change or
Polishing, the essence of used technical solution is still as the utility model, therefore it should also be as the protection in the utility model
In range.
