Abstract
The utility model provides a sealed packaging bag comprising a first plastic cover and a second plastic cover. The periphery of the first plastic cover is connected with the periphery of the second plastic cover by hot seal, a sealing bag cavity is formed between the first plastic cover and the second plastic cover, a tearing port is arranged on a hot-seal connecting part between the first plastic cover and the second plastic cover, a strip-shaped concave strip is arranged on the inner wall of the first plastic cover, and a strip-shaped convex strip which is clamped with the strip-shaped concave strip to be in sealing connection is arranged on the inner wall of the second plastic cover, and the strip-shaped concave strip and the strip-shaped convex strip are positioned below the tearing port. When the sealed packaging bag is torn open, the bag cavity can be sealed again by the mutual clamping sealing connection between the strip-shaped concave strip and the strip-shaped convex strip, and during the using process of the sealed packaging bag, the strip-shaped concave strip and the strip-shaped convex strip can be separated and clamped repeatedly, so that the food in the bag can be prevented from becoming damp, being polluted or scattering outside of the bag after the sealed packaging bag is torn open, the quality guarantee period of the food is prolonged, and the sealed packaging bag is convenient to carry.
Description
Technical field
The utility model relates to a kind of sealing bags.
Background technology
Sealing bags is widely used in the various food of packing; Such as candy, edible salt, monosodium glutamate etc.; Existing sealing bags comprises first plastic cover and second plastic cover; Is connected through heat-sealing between the periphery of the periphery of first plastic cover and second plastic cover, formation sealing bag chamber between first plastic cover and second plastic cover, the heat-sealing connecting portion between first plastic cover and second plastic cover is provided with tearing port.During use; Can tear sealing bags easily through tearing port; It is but not enough below existing this sealing bags exists: because the food in the packaging bag can all not use usually immediately; And avulsed sealing bags can not be sealed once more, outside remaining food makes moist with regard to causing for this, pollution, food the are scattered bag, is difficult to preserve and carry.
The utility model content
The technical matters that the utility model solves is: a kind of sealing bags is provided, can repeats sealing after making sealing bags torn.
The technical scheme of the utility model is: a kind of sealing bags; Comprise first plastic cover and second plastic cover; Is connected through heat-sealing between the periphery of the periphery of first plastic cover and second plastic cover, formation sealing bag chamber between first plastic cover and second plastic cover, the heat-sealing connecting portion between first plastic cover and second plastic cover is provided with tearing port; It is characterized in that; The inwall of said first plastic cover is provided with recessed of strip, and the inwall of said second plastic cover is provided with and recessed strip raised line that fastens and be tightly connected of said strip, and recessed of said strip and said strip raised line are positioned at said tearing port below.
Distance between recessed of said strip, said strip raised line and the said tearing port is 10mm～15mm.
Recessed of said strip, said strip raised line are fixed on the corresponding first plastic cover inwall, second plastic liner through heat bonding respectively.
The salient of the depressed part of the recessed sliver transvers section of said strip and said strip raised line cross-sectional plane all is circular arc, and said circular arc is major arc.
The beneficial effect of the utility model is:
1, owing to be connected through sealing between the periphery of the periphery of first plastic cover and second plastic cover, formation sealing bag chamber between first plastic cover and second plastic cover, the heat-sealing connecting portion between first plastic cover and second plastic cover is provided with tearing port;, sealing bags can keep sealing before being torn for a long time; Simultaneously, because the inwall of said first plastic cover is provided with recessed of strip, the inwall of said second plastic cover is provided with and recessed strip raised line that fastens and be tightly connected of said strip; Recessed of said strip and said strip raised line are positioned at said tearing port below; After sealing bags is torn, can engage each other to be tightly connected through recessed of strip and strip raised line again a bag chamber is resealed, and in use can recessed of strip, strip raised line separated repeatedly, engage; Thereby after having avoided sealing bags to be torn; Outside food in the bag makes moist, pollution, food the are scattered bag, prolonged the shelf-life of food, and be easy to carry.
2, because the depressed part of the recessed sliver transvers section of said strip and the salient of said strip raised line cross-sectional plane all are circular arc, and said circular arc is major arc, so engaging between recessed of strip and the strip raised line is tightr, has improved sealing property.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A line scheme drawing of Fig. 1;
Fig. 3 is the structural representation of recessed of strip after being separated from each other with the strip raised line.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1～Fig. 3; A kind of sealing bags; Is connected formation sealing bag chamber 3 between first plastic cover 1 and second plastic cover 2 through heat-sealing between the periphery that comprises first plastic cover 1 and second plastic cover, 2, the first plastic covers 1 and the periphery of second plastic cover 2; Heat-sealing connecting portion 7 between first plastic cover 1 and second plastic cover 2 is provided with tearing port 4; The inwall of first plastic cover 1 is fixed with recessed 5, the second plastic cover 2 of strip through heat bonding inwall is fixed with the strip raised line 6 that fastens and be tightly connected with recessed 5 of strip through heat bonding, and recessed 5 of strip and strip raised line 6 are positioned at tearing port 4 belows.For recessed 5 of strip and strip raised line 6 engage each other seal after, can enlarge the spatial accommodation in sealing bag chamber, in the present embodiment, the distance between recessed 5 of said strip, said strip raised line 6 and the said tearing port 4 is 10mm, this distance can also be 15mm.The salient of the depressed part of recessed 5 cross-sectional plane of strip and strip raised line 6 cross-sectional planes all is circular arc, and circular arc is major arc.
