Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper bags, in particular to a sealed paper bag. Background Art
[0002] Paper bags refer to bags made of paper materials as the main body. Generally, the sealing effect of the bag mouth is relatively poor, which affects the insulation effect of the items stored inside.
[0003] After searching, the patent application number CN202223000570.X discloses a paper bag with an inner-sticked and outer-turned seal, including a paper bag body, and symmetrically arranged hand ropes are pasted on two inner sides corresponding to the top of the paper bag body with double-layer hand-stickers, and the double-layer hand-stickers include an inner hand-sticker pasted on the inner side of the top of the paper bag body, and an outer hand-sticker pasted on the outer surface of the inner hand-sticker and clamped and pasted on the two ends of the bottom of the hand, and the outer hand-sticker is provided with a seal sticker folded downward and pasted on the inner side of the paper bag body and turned up to protrude from the bag mouth to form an outer turn, and the outer side of the seal sticker is coated with a seal sticker adhesive and the corresponding seal sticker adhesive position is covered with release paper;
[0004] The above application document achieves bag sealing by setting an adhesive sealing label at the bag opening, but the adhesive seal will still cause the bag cavity to contact the outside, affecting the thermal insulation effect. At the same time, the bag itself has a certain degree of air permeability due to the setting of paper material, which affects the thermal insulation effect.
[0005] Therefore, we propose a seal-sealed paper bag. Utility Model Content
[0006] In view of the deficiencies of the prior art, the utility model provides a sealed paper bag, which solves the problem that the block-shaped patch in the prior device has a poor sealing effect on the inner cavity of the paper bag body.
[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions: a sealed paper bag, comprising a paper bag body, a layer of high temperature resistant and waterproof oil film is adhered to the whole inner wall of the paper bag body;
[0008] A sealing component is fixedly installed on the upper part of the inner side of the paper bag body;
[0009] The sealing assembly is connected by front and rear seals, a rear seal and four groups of side seals therebetween. A positive blocking groove is opened on the inner wall of the front seal, a side blocking groove is opened on the inner wall of the rear seal, a side blocking strip matched with the positive blocking groove and the side blocking groove is fixedly installed on the inner wall of the side seal, and a positive blocking strip is fixedly installed on the inner wall of the rear seal.
[0010] Preferably, the side blocking strips, side blocking grooves and main blocking grooves are all three-quarter arc-shaped grooves, and the main blocking strips and side blocking strips are all three-quarter arc strips. The setting of the side blocking strips, side blocking grooves and main blocking groove arc grooves and the main blocking strips and side blocking strip arc strips can ensure the sealing when they are assembled.
[0011] Preferably, the components in the sealing assembly are all made of soft rubber. The provision of the soft rubber facilitates its deformation during installation and subsequent press-fitting, thereby ensuring sealing performance.
[0012] Preferably, a spiral strip located on the rear side is fixedly installed on the top of the paper bag body, and a sticking strip with the same shape and specification as the spiral strip is fixedly installed on the outer wall on the front side of the paper bag body. The adhesion of the spiral strip and the sticking strip can perform secondary sealing on the space inside the paper bag body from the top side, further ensuring the sealing effect.
[0013] Preferably, a layer of sealant is adhered to the outer walls of the spiral strip and the sticking strip.
[0014] The utility model provides a sealed paper bag with a seal having the following beneficial effects:
[0015] The sealed paper bag can ensure the sealing of the inner wall by providing a waterproof oil film on the inner wall of the paper bag body. When in use, the space inside the paper bag body is sealed from the top side by inward clamping between the sealing components. At the same time, the adhesion between the rotating strip and the sticking strip performs secondary sealing on the seal, thereby ensuring the heat preservation of the items stored inside, and solving the problem that the block-shaped patch in the existing device has a poor sealing effect on the inner cavity of the paper bag body.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example 1: Figure 1-4 As shown: a sealed paper bag, comprising a paper bag body 1, a layer of high temperature resistant and waterproof oil film is adhered to the inner wall of the paper bag body 1; a sealing assembly 2 is fixedly installed on the upper half of the inner side of the paper bag body 1; the sealing assembly 2 is connected by a front seal 21, a rear seal 22 and four sets of side seals 23 therebetween, a front seal 21 is provided with a positive blocking groove 27 on the inner wall, a rear seal 22 is provided with a side blocking groove 25 on the inner wall, and a side seal 23 is fixedly installed with a side seal 23 that is fitted with the front blocking groove 27 and the side blocking groove 25. The paper bag body 1 has a sealing strip 24, and a positive sealing strip 26 is fixedly installed on the inner wall of the rear sealing strip 22; the side sealing strip 24, the side sealing groove 25 and the positive sealing groove 27 are all three-quarter arc grooves, and the positive sealing strip 26 and the side sealing strip 24 are all three-quarter arc strips; the components in the sealing assembly 2 are all made of soft rubber; the top of the paper bag body 1 is fixedly installed with a rotating strip 3 located on the rear side, and the outer wall of the front side of the paper bag body 1 is fixedly installed with a sticking strip 4 with the same shape and specification as the rotating strip 3; a layer of sealing glue is adhered to the outer walls of the rotating strip 3 and the sticking strip 4;
[0023] The sealed paper bag can ensure the sealing of the inner wall by providing a waterproof oil film on the inner wall of the paper bag body 1. When in use, the space inside the paper bag body 1 is sealed from the top side by the inward clamping between the sealing components 2. At the same time, the adhesion between the rotating strip 3 and the sticking strip 4 performs secondary sealing on the seal, thereby ensuring the heat preservation of the items stored inside, and solving the problem that the block-shaped patch in the existing device has a poor sealing effect on the inner cavity of the paper bag body 1.

When in use, the sealing component 2 is squeezed inward from the top side. At this time, the side blocking strip 24 on the outer wall of the side sealing strip 23 is sleeved on the inner side of the positive blocking groove 27 and the side blocking groove 25, and the positive blocking strip 26 is sleeved on the inner side of the positive blocking groove 27 to ensure the sealing effect of the sealing component 2. Then the rotating strip 3 is rotated to make it close to the outer wall of the sticking strip 4 to further ensure the sealing effect of the sealing part.
