Description
Technical Field
The utility model relates to a packaging material for container transportation, in particular to a self-sealing sea bag.
Background
The container body has poor sealing performance and is not corrosion-resistant, so when the container is used for transporting powdery or granular goods, in order to prevent pollution and leakage and also prevent the goods from being stained and corroded with a metal container body, a container lining bag made of a plastic film is usually required to be sleeved in the container, and the sea bag is one of the container lining bags. In the long-distance transportation process at sea, the humidity and the salinity of the surrounding environment are higher, the sealing performance requirement on the sea bag is higher, the common sea bag mostly adopts a cylindrical material inlet and outlet, and the material outlet is bound by using a binding belt in the transportation process so as to achieve the sealing purpose. However, the effect of such a lashed seal varies from person to person, the consistency is poor, and it is not easy to find if the lashed is not firm. Another chinese patent 2019212853056 of the applicant discloses a "damp-proof dry container sea bag", publication No. CN210794380U, in which an external-mounted drying strip is suspended in the sea bag, and at the same time, the drying strip is disposed on the inner wall of the sea bag, so that after the powder product is loaded, the interior and exterior of the product can be simultaneously damp-proof, and the purpose of preventing the product in the sea bag from being damp and deteriorating is sequentially achieved. However, the sea bag does not solve the sealing problem well, the desiccant has a certain saturated water absorption capacity, and the desiccant does not have a dampproof effect after reaching the saturated water absorption capacity when the environment humidity is particularly high or the environment is in a humid environment for a long time. In addition, certain special chemical products or products with higher water content are not suitable for drying agents, but still have the requirement of sealed storage and transportation.

Preferably, the circumferences of the two ends of the sealing ring are equal.
Through this scheme, can further reduce the manufacturing cost of sealing ring to the rear end opening is big, conveniently loads and unloads goods.
Preferably, the perimeter of the outer end of the sealing ring is less than the perimeter of the inner end but greater than twice the width of the rear end of the pouch.
Through this scheme, seal ring rear end opening is less, and the length of self-sealing layering is short, is favorable to improving sealed effect.
Preferably, the self-sealing pressing strip comprises a pressing strip female head with a groove-shaped structure in section and a pressing strip male head with a strip-shaped structure in section and matched with the groove-shaped structure of the pressing strip female head, and the lengths of the pressing strip female head and the pressing strip male head respectively occupy half of the circumference of the outer end edge of the sealing ring.
Through this scheme, with the public head of layering and the female head lock of layering together can realize effective seal, convenient operation and repeatedly usable.
Preferably, the lower ends of the pressing strip female head and the pressing strip male head are fixedly connected with heat sealing base bands, the heat sealing base bands are of strip-shaped sheet structures, and the back surfaces of the heat sealing base bands are adhered to the inner wall of the sealing ring.
Through this scheme, can be convenient and fast ground with layering female head and layering male head connect on sealing the ring, convenient production manufacturing reduces manufacturing cost.
After the technical scheme is adopted, the sea bag is sealed conveniently and reliably by adopting the self-sealing layering, so that the air flow inside and outside the sea bag is isolated, the cargo in the bag is prevented from being wetted, and the sea bag has the advantages of simple structure, good sealing effect, convenience in operation and low cost.

Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings. Wherein like parts are designated by like reference numerals. It should be noted that, as used in the description below, the words "front", "back", "left", "right", "upper" and "lower" refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions away from the geometric center of a particular component, respectively.
As shown in fig. 1, the self-sealing sea bag comprises a bag body 1 with a rectangular cylindrical structure and a closed front end, wherein the bag body 1 is formed by heat sealing and bonding PE films or other plastic films and other materials, and a plurality of hanging strips 2 are fixedly arranged at the upper end of the bag body and are used for being fixed on hanging positions at corresponding positions of the inner wall of a container. The rear end of the bag body is fixedly connected with a sealing ring 3, and the sealing ring 3 is of a thin-wall annular structure and is made of the same PE film or other plastic films as the bag body 1. The circumference of the inner end of the sealing ring 3 is equal to that of the rear end of the bag body 1, the inner end of the sealing ring 3 is fixedly connected to the rear end of the bag body 1 through a plastic heat sealing or gluing process, and a self-sealing pressing strip is arranged at the edge of the outer end of the sealing ring 3.
As shown in fig. 4 and 5, the self-sealing bead comprises a female bead head 4 with a groove-shaped structure in cross section and a male bead head 5 with a strip-shaped structure in cross section and matched with the groove-shaped structure of the female bead head 4, the female bead head 4 and the male bead head 5 are made of plastic with certain toughness and elasticity, the hardness is slightly greater than that of the material of the bag body 1, and the lengths of the female bead head 4 and the male bead head 5 respectively occupy half of the circumference of the outer end edge of the sealing ring 3. The lower ends of the pressing strip female head 4 and the pressing strip male head 5 are fixedly connected with a heat sealing base band 6, the heat sealing base band 6 is of a strip-shaped sheet structure, and the back surface of the heat sealing base band 6 is adhered to the inner wall of the sealing ring 3. As shown in figure 5, when in use, the back surface of the heat sealing baseband 6 is connected to the inner wall of the sealing ring 3 by adopting a plastic heat sealing or gluing process, and after goods are loaded, the sea bag can be sealed by only pressing the male end 5 of the pressing strip into the groove of the female end 4 of the pressing strip so as to tightly attach the male end and the female end together.
The sealing ring can have two structures, as shown in fig. 2, the circumferences of the two ends of the sealing ring 3 are equal and equal to the circumference of the rear end of the bag body 1, at this time, the inner end of the sealing ring 3 is just in butt joint with the rear end of the bag body 1, but the length of the self-sealing pressing strip at the outer end of the sealing ring 3 is half of the circumference of the rear end of the bag body 1, which is obviously larger than the width of the rear end of the bag body 1, and the longer self-sealing pressing strip can conveniently load and unload cargoes, but is unfavorable for sealing.
