According to the compression bag, the two sealing strips are arranged at the bag opening part, one sealing strip with a quick-pull structure is arranged on the outer side, and the other sealing strip is arranged inside and in line with the exhaust hole, so that gas in the bag can be effectively discharged and effectively sealed, and the compression bag is simple in structure and convenient to operate.
Description
Technical Field
The utility model belongs to the field of vacuum compression bags, and particularly relates to a double-sealing-strip compression bag.
Background
Vacuum compression bag among the prior art generally adopts the form of single strip of paper used for sealing, and the compression bag of this kind of structure is difficult to the quick discharge of bag interior gas on the one hand, and the dislocation appears easily in pressing of on the other hand single strip of paper used for sealing, leads to sealed poor, and the dress continues to contact with the outside air in the object in the bag, reduces the dampproofing damp-proofing effect of vacuum compression bag.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present invention provides a double-seal compressed bag, especially a compressed bag for food packaging.
The technical purpose is achieved, the technical effect is achieved, and the utility model is realized through the following technical scheme:
the utility model provides a two sealing strip compression bags, includes the compression bag body, sets up first sealing strip and the second sealing strip at compression bag opening portion, first sealing strip sets up the marginal line position at the opening, the second sealing strip sets up the inside position of compression bag, first sealing strip is the sealing strip that has the slider, the length of second sealing strip is less than or equal to the length of first sealing strip.
As a further improvement of the utility model, the sealing device further comprises a vent hole which is arranged in line with the second sealing strip.
As a further improvement of the utility model, the exhaust holes are arranged at the positions of both ends of the second sealing strip.
As a further improvement of the utility model, the second sealing strip is of a sectional structure, and the exhaust hole is arranged at the position of a sectional point.
As a further improvement of the utility model, the opening part is provided with a thickened area with the width of 1-2 cm.
As a further improvement of the present invention, the distance between the first sealing tape and the second sealing tape is less than 0.5 cm.
The utility model has the beneficial effects that: according to the compression bag, the two sealing strips are arranged at the bag opening part, one sealing strip with a quick-pull structure is arranged on the outer side, and the other sealing strip is arranged inside and in line with the exhaust hole, so that gas in the bag can be effectively discharged and effectively sealed, and the compression bag is simple in structure and convenient to operate.
Drawings
FIG. 1 is a schematic view of a first embodiment of a vacuum compression bag of the present invention;
FIG. 2 is a schematic structural view of a second embodiment of the vacuum compression bag of the present invention;
wherein: 1-compression bag body, 100-opening part, 2-first sealing strip, 200-sliding block, 3-second sealing strip and 4-vent hole.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
The following detailed description of the principles of the utility model is provided in connection with the accompanying drawings.
The structure of the double-sealing compressed bag shown in fig. 1-2 comprises a compressed bag body 1, a first sealing strip 2 and a second sealing strip 3 arranged at the opening part 100 of the compressed bag.
The opening is a thickened area with a width of 1-2cm because the bag opening bears the largest tearing force. The film thickness of the thickened area is 2-3 times of that of other areas of the bag body. The first 2 and second 3 sealing strips are arranged in the thickened area.
The first sealing strip 2 is arranged at the position of the edge line of the opening part and is a compression bag with a quick-pull structure of the sliding block 200, so that the quick operation is realized.
The second sealing strip 3 is arranged at the position inside the compression bag, and the distance between the first sealing strip 2 and the second sealing strip 3 is less than 0.5 cm. Like this first sealing strip 2 adopts the quick closedown to for the restricted position of second sealing strip 3, be difficult to the condition that appears the dislocation when guaranteeing that second sealing strip 3 closes.
The length of the second sealing strip 3 is shorter than that of the first sealing strip 2, and the collinear position of the second sealing strip 3 is provided with an exhaust hole 4 for exhausting.
The vent hole 4 is provided with various structures, for example, as shown in the first embodiment of fig. 1, the vent hole 4 is provided at both end positions of the second sealing tape 3.
Or as shown in the second embodiment of fig. 2, the second sealing strip 3 is of a sectional structure, and the exhaust hole 4 is arranged at the position of a sectional point.
Based on the compression bag of above structure, in the use, earlier first sealing strip 2 of quick closure, later manual closing second sealing strip 3, then first sealing strip 2 is opened fast, and manual exhaust waits that gas discharge back, closes first sealing strip 2 again, seals completely to the compression bag.
In addition, the length of the second sealing strip 3 can also be equal to that of the first sealing strip 2, a structure without an exhaust hole is adopted, and only when the second sealing strip 3 is closed, an incomplete closing mode can be adopted, and a section of exhaust gap is reserved.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
