Abstract
Description
Technical Field
[0001] This application belongs to the field of plastic bag technology, and particularly relates to an integral double-chamber plastic bag for sealing adhesive. Background Technology
[0002] Sealants are mainly divided into single-component sealants and two-component sealants. Two-component sealants are made by filling two different sealant putties into a rigid plastic tube. When used, the two different sealant putties are extruded and mixed at the same time to form a sealant with adhesive function. However, when flexible plastic bags are used to hold different putties, the space inside the bag needs to be divided into two parts, and it is necessary to avoid the two putties from mixing inside the bag due to gaps. Utility Model Content
[0003] In order to solve the above problems, this application provides an integral double-chamber plastic bag for sealant.
[0004] The purpose of this application is to provide an integral double-chamber plastic bag for sealant, which utilizes a second film to cooperate with a first film to form an inner sealing edge inside the plastic bag, forming a first chamber and a second chamber separated inside the plastic bag, with the first chamber and the second chamber respectively filled with different types of sealant.
[0005] To achieve the purpose of this application, the technical solution of this application is as follows:
[0006] A one-piece double-chamber sealant bag includes a first film, a second film disposed on the first film, two sides of the second film connected to the first film, the two sides of the first film connected together, the head ends of the first film and the tail ends of the first film and the second film being sealed by the same sealing ring, the space of the first film being divided into a first chamber and a second chamber by the second film, and the first chamber and the second chamber being filled with different sealant.
[0007] Furthermore, the first film has a first transparent strip, through which the clay inside the first cavity can be observed.
[0008] Furthermore, the first film has a second transparent strip through which the clay inside the second cavity can be observed.
[0009] Furthermore, the outer walls of the two sides of the second film are connected to the inner walls of the first film, and the connection area of the first film and the second film forms the first inner encapsulation edge and the second inner encapsulation edge.
[0010] Furthermore, the inner wall of one side of the first film and the outer wall of the other side of the first film are connected together, and the connection area of the side of the first film forms the outer encapsulation edge.
[0011] Furthermore, the volume ratio of the first chamber to the second chamber is 1:1 to 1:12.
[0012] Furthermore, the sealing ring seals the head and tail ends of the first and second chambers. Once the sealing ring is removed, both the first and second chambers are connected to the outside.
[0013] Furthermore, several spaced indentations are provided on both the first inner packaging edge and the second inner packaging edge.
[0014] Furthermore, several spaced indentations are provided on the outer packaging edge.
[0015] Furthermore, the putty in the first chamber is the first type of two-component sealant, and the putty in the second chamber is the second type of two-component sealant. The first type of putty and the second type of putty are mixed together to form a sealant with adhesive function.
[0016] Compared with the prior art, the beneficial effects of this application are as follows:
[0017] 1. In this application, the second film is connected to the first film, and the connection between the first film and the second film is located inside the plastic bag, reducing the connection edge on the outside of the plastic bag. The second film and the first film form an inner sealing edge inside the plastic bag, forming a first chamber and a second chamber separated inside the plastic bag. The first chamber and the second chamber are respectively filled with different types of putty. The sealing ring seals the head and tail ends of the plastic bag. After the sealing ring is opened, the two different types of putty are squeezed out of the plastic bag at the same time.
[0018] 2. This application includes a transparent strip on the plastic bag, through which the colors of the two different types of putty inside the bag and their usage can be seen.
[0019] 3. This application presses indentations on the packaging edge to ensure a sealed connection. In addition, when the putty is extruded, the plastic bag will deform and fold. During the folding process, the indentations help the plastic bag to fold in a regular manner, so that the putty inside the plastic bag can be extruded at the same time, ensuring that the two types of putty are extruded in a specific ratio.

[0030] Example 1
[0031] This embodiment is a one-piece double-chamber plastic bag for sealant. The bag 1 contains two different types of sealant putty. The two putty are used together to form a sealant with adhesive properties. Specifically, as shown... Figures 1-4As shown, the plastic bag 1 in this embodiment includes a first film 3, on which a second film 4 is arranged. In one implementation, the material of the first film 3 is similar to or the same as that of the second film 4, facilitating procurement and connection between the films. Two sides of the second film 4 are connected to the first film 3, and the outer walls of the two sides of the second film 4 are connected to the inner walls of the first film 3. The connection area of the first film 3 and the second film 4 forms a first inner sealing edge 5 and a second inner sealing edge 6. During connection, the first film 3 and the second film 4 can be fixed together by heat pressing or other methods, forming a cavity between the second film 4 and the first film 3, referred to here as the first cavity. The two sides of the first film 3 are connected together, and the inner wall of one side of the first film 3 is connected to the outer wall of the other side of the first film 3. The connection area of the sides of the first film 3 forms an outer sealing edge 7. During connection, one side of the first film 3 can be fixed to the other side of the first film 3 by heat pressing or other methods, so that the outer sealing edge 7 is located on the outside of the plastic bag 1, and the inner sealing edge is located inside the plastic bag 1. The aforementioned edges are along the plastic bag 1. Arranged along the length direction, the first film 3 and the second film 4 have their heads sealed by the same sealing ring 2, and their tails sealed by the same sealing ring 2. The sealing ring 2 is made of metal. By pressing the sealing ring 2, it deforms and locks the heads and tails of the plastic bag 1. The sealing ring 2 seals the heads and tails of the first and second chambers. The space of the first film 3 is divided into the first chamber and the second chamber by the second film 4. Depending on the type of sealant, the volume of the first chamber and the second chamber can vary. For example, the volume ratio of the first chamber to the second chamber may be... The ratio can be 1:1 to 1:12, or other volume ratios. The putty in the first chamber is the first type of two-component sealant, and the putty in the second chamber is the second type of two-component sealant. As one usage method, when using it, the sealing ring 2 needs to be removed first, such as by cutting or trimming the sealing ring 2, so that both the first and second chambers are connected to the outside. The two types of putty can then be squeezed out from the first and second chambers simultaneously when the glue bag 1 is squeezed. Under the action of the mixer that works with the glue gun, the first type of putty and the second type of putty are mixed together to form a sealant with adhesive function.
[0032] As one implementation, the first film 3 has a first transparent strip 8 through which the putty inside the first cavity can be observed.
[0033] As one implementation, the first film 3 has a second transparent strip 9 through which the clay inside the second cavity can be observed.
[0034] The transparent strip in this embodiment can be formed by the following scheme: the first film 3 is made of transparent plastic material. When printing the outer packaging pattern, information and other content on the first film 3, the corresponding area is left unprinted. The first transparent strip 8 and the second transparent strip 9 are formed in a specific area of the first film 3.
[0035] As one implementation scheme, in this embodiment, several spaced indentations 10 are arranged on both the first inner packaging edge 5 and the second inner packaging edge 6. Several spaced indentations 10 can also be arranged on the outer packaging edge 7. The indentations 10 are formed as follows: When the packaging edge is formed, the first film 3 and the second film 4 move forward. The packaging edge passes through a pressure roller that rotates passively in place. The protrusions on the pressure roller press indentations 10 on the packaging edge that has just been hot-pressed. For example, the width of each indentation 10 can be between 0.1mm and 1mm, and the interval between adjacent indentations 10 can be between 3mm and 5mm.
[0036] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
[0037] While the specific embodiments of this application have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this application. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this application are still within the scope of protection of this application.
