Description

Separated packaging bag

Technical Field

The utility model relates to the technical field of packaging bags, in particular to a separated packaging bag.

Background

Sealed packages are one of the products commonly used in modern life and are currently widely used in different fields. For different purposes, the sealed package may be classified into various types of zipper bags, vacuum bags, profile bags, and the like. Among them, in the fields of medical treatment, beauty treatment, food, etc., in order to avoid gradual loss of original characteristics of the mixture product with the increase of time, a divided type packaging bag has been presented. The separate packaging bag can not mix the materials in the different cavities until needed, so as to ensure that the consumer can finally obtain the optimal use effect of the product. According to the mode of mixing and opening the cavities, the divided packaging bags commonly used in the market at present can be mainly divided into two modes of extrusion mixing and external pull ring mixing. Different opening forms of packages suffer from different drawbacks.

Extrusion mixed packaging bags generally need to extrude one of the packaging cavities, and the pressure breaks the original sealing structure between the two packaging cavities, so that materials in the two packaging cavities are mixed. This approach requires relatively large compression forces for some consumers, thus reducing the use experience. On the other hand, this type of package requires a high material selection or direction when the consumer squeezes, and if the force is applied too hard or the direction of the force is not correct, there is a possibility that the package may be broken through directly by the material.

The packaging bag with the external pull ring is characterized in that the sealing structure between the two packaging cavities is broken by pulling the pull ring, so that the aim of mixing materials is fulfilled. The mode can appear tearing the too big phenomenon of pulling the scope when using to make the object in the packing chamber spill. In addition, it should be noted that, in order to facilitate the opening of the user, the sealing structure between the different cavities is usually a weak sealing edge, which leads to the sealing structure being easily damaged in advance by being squeezed during the transportation process, i.e. the structural stability of this type of packaging bag is poor.

Therefore, it is necessary to provide a novel divided packaging bag which is mixed with extrusion and pull ring in different use modes, so that the stability of the structure in the transportation process is improved, and the use experience is optimized.

Example 1

Fig. 1 is a schematic view showing the structure of the divided packaging bag of the present embodiment in a closed state, and fig. 2 and 3 are schematic views showing the structure of the divided packaging bag of the present embodiment in a folded state and an opened state, respectively. Referring to fig. 1 to 3 in combination, the present embodiment provides a divided type packaging bag, which includes a packaging bag body 100 and a separation band 200 provided on the packaging bag body 100, wherein the packaging bag body 100 is provided with at least two cavities, and the separation band 200 is connected with different cavities. The middle part of the isolation belt 200 is provided with a pre-die cutting line 23, and when the pre-die cutting line 23 is opened and a channel opening 24 is formed, materials in different cavities are mixed through the channel opening 24.

Specifically, the shape of the package 100 may be designed into a rectangular shape, a round shape, or a special shape according to individual requirements. In this embodiment, the package 100 has a rectangular shape. The package 100 is provided with a first cavity 11 and a second cavity 12. The isolation belt 200 is built in the package 100, connects different opposite surfaces of the package 100, and isolates the first cavity 11 from the second cavity 12. The first cavity 11 and the second cavity 12 are separately arranged at the upper side and the lower side of the isolation belt 200, and the first cavity 11 and the second cavity 12 are not communicated with each other. Sealing edges 13 are arranged on the left side and the right side of the packaging bag body 100, and the isolation belt 200 is positioned at the connecting line between different cavities and is connected with the sealing edges 13 on the left side and the right side, so as to penetrate the packaging bag body 100. Of course, in some embodiments, the isolation strip 200 may be disposed in the middle of the package 100, centered at the connecting line of the different cavities, or near the sealing edge 13.

The separator 200 is a sheet structure including a fixing portion 25 and a passage portion 26. The fixing parts 25 are respectively arranged at the left side and the right side of the channel part 26 and are connected with the sealing edge 13, and the fixing parts 25 are simultaneously connected with different bag surfaces. The channel portion 26 is provided with a sealing piece connected to the fixing portion 25. A pre-die cutting line 23 is arranged between the sealing sheets, and the pre-die cutting line 23 extends along the length direction of the isolation belt 200 and is connected with the fixing parts 25 at the left side and the right side.

In the present embodiment, the channel portion 26 is provided with two sheets including the first sheet 21 and the second sheet 22. The package 100 includes opposing first and second sides. Wherein the first sealing piece 21 is fixed on the first bag surface in a heat sealing mode, and the second sealing piece 22 is fixed on the second bag surface in a heat sealing mode. In a sealed state, the first seal 21 is connected to the second seal 22. The first sealing piece 21 is close to the first cavity 11, and the second sealing piece 22 is close to the second cavity 12. Accordingly, the separator 200 achieves separation of the first and second cavities 11 and 12 by the first and second seal sheets 21 and 22 in common.

Folding and squeezing the divided packaging bag to enable different cavities of the divided packaging bag to be converted from a closed state to an open state. Specifically, the divided packaging bag is folded with the line of the pre-mold cut 23 as the axis, so that the first cavity 11 and the second cavity 12 are brought close to each other. At this time, the pre-die cut line 23 is broken by the folding. Further, the fixing portion 25 applies force in the direction of the channel portion 26 to press, so that the first sealing piece 21 and the second sealing piece 22 drive the first bag surface and the second bag surface to separate, and meanwhile, the isolation belt 200 forms a three-dimensional channel opening 24 at the original pre-die-cut line 23. The passage opening 24 serves as a passage connecting the first chamber 11 and the second chamber 12, so that the materials in the different chambers are fully mixed.

The opening process of the separator 200 includes two steps of folding and pressing. Wherein the pre-die cut 23 can be broken by folding in preparation for communication of the first cavity 11 and the second cavity 12. Compared with the mode of opening the isolation belt 200 by extruding the cavity, the folding mode effectively reduces the force required for opening the isolation belt 200, and simultaneously avoids the possibility of material leakage from a non-channel due to the fact that the packaging bag is broken caused by overlarge applied force or incorrect applied force direction. Compared with a tearing and pulling mixed packaging bag, the partitioned packaging bag provided by the embodiment realizes the mixing of the first cavity 11 and the second cavity 12 under the condition that the integrity of the packaging bag body 100 is not damaged, and ensures that the packaging bag body 100 has neatness before and after use.

It is added that, in order to be convenient for open the isolation structure, the isolation structure between different cavities is usually set to be weak sealed, that is, the bonding strength of the isolation structure is weak, so that the isolation structure is easy to open due to extrusion in the transportation process of the package bag. In the divided packaging bag provided in this embodiment, the isolation strip 200 isolates different cavities by the first sealing piece 21 and the second sealing piece 22 which are connected. Wherein, the first sealing piece 21 and the second sealing piece 22 are connected and fixed with the bag surface in a heat sealing mode. The first sealing piece 21 and the second sealing piece 22 are connected with the bag surface to form a strong heat sealing edge, namely, the bonding strength of the first sealing piece 21 and the second sealing piece 22 with the bag surface is higher. And also because of the connection of the pre-mold cut 23 in the middle of the first and second dies 21, 22. Therefore, during transportation, the first sealing piece 21, the second sealing piece 22 and the pre-molded line 23 are not easy to open under the action of extrusion, so that the structural stability of the divided packaging bag of the embodiment is ensured.

In summary, this embodiment provides a divided packaging bag, realizes the isolation of different cavitys through the sealing piece that is connected with different bag face heat-seal to realize the intercommunication between different cavitys through opening of pre-die cutting line. The isolation belt 200 is a strong heat sealing edge, so that the stability of the structure of the divided packaging bag is effectively ensured. Meanwhile, the opening mode of the isolation belt 200 effectively reduces extrusion force, reduces the risk of package bag breakage in the opening process, and finally optimizes the use experience of the separated package bag.

Example 2

This embodiment is further described on the basis of embodiment 1.

Referring to fig. 1 to 3 in combination, in order to further optimize the process of opening the separator 200 for the divided type packing bag, the separator 200 is further provided with a die cut site. The separator 200 is a sheet structure and is integrally formed through a die-cutting process. Wherein, the fixing portion 25 is a square sheet structure and is arranged at two ends of the channel portion 26. The channel part 26 comprises a sealing piece, a first die cutting position 31 is arranged in the middle of the sealing piece, and a second die cutting position 32 is arranged at the joint of the sealing piece and the fixing part 25.

In the present embodiment, the channel portion 26 is provided with two pieces of the first and second seal pieces 21 and 22, respectively, and the first and second seal pieces 21 and 22 are separated after the pre-die cut line 23 is broken. The first sealing piece 21 and the second sealing piece 22 are respectively provided with a first die cutting position 31 and a second die cutting position 32, and the direction of the die cutting positions on the first sealing piece 21 is opposite to the direction of the corresponding die cutting positions of the second sealing piece 22.

Specifically, the first sealing sheet 21 is heat-sealed on the first bag surface, the second sealing sheet 22 is heat-sealed on the second bag surface, the first die-cutting position 31 of the first sealing sheet 21 is positioned on one side away from the first bag surface, and the first die-cutting position 31 of the second sealing sheet 22 is positioned on one side close to the first bag surface. The second die cut locations 32 at the two ends of the first flap 21 are on the side near the first pocket side and the second die cut locations 32 at the two sides of the second flap 22 are on the side far from the first pocket side. After the divided packaging bag is folded and extruded, when the first bag surface is seen in front view, the first die cutting position 31 and the second die cutting position 32 enable the first sealing piece 21 to be protruded towards one side where the first bag surface is located, and the second sealing piece 22 is protruded towards one side where the second bag surface is located, so that the first sealing piece 21 and the second sealing piece 22 can conveniently form a rhombic channel opening 24 at the pre-cutting die opening, and the first cavity 11 and the second cavity 12 are communicated.

Note that the die-cut site does not completely cut the separator 200 to break, and the die-cut site may be formed by die-pressing. The arrangement of the first die cutting position 31 and the second die cutting position 32 enables the process of extruding and forming the channel port 24 to be smoother, and meanwhile, the force during extrusion is guided, so that the experience of the divided packaging bag when the isolation belt 200 is opened is effectively optimized. In addition, the sheet-like securing portion 25 also provides a good point of application for squeezing the divided packing bag, and also optimizes the process of opening the separator 200.

Of course, there is no particular limitation in the distribution position and number of the die cut bits, etc. In the actual production process, the distribution position or the number of the die cutting positions can be improved according to the shape or the personalized requirement of the packaging bag body 100 so as to meet different requirements.

Further, the packaging bag body 100 can be made of PET, PE or other plastic materials, and an aluminum foil layer is covered outside the packaging bag body 100, so that the partitioned packaging bag has the characteristics of moisture resistance, water resistance, high air tightness, light shielding property and the like.

Example 3

Fig. 4 and 5 show schematic structural views of another separator 200 in a closed state and a mixed state, respectively. Referring to fig. 1 to 5 in combination, the present embodiment provides a divided type packing bag. The divided packaging bag comprises a packaging bag body 100 and a separation belt 200 arranged on the packaging bag body 100, the packaging bag body 100 is divided into two cavities by the separation belt 200, a pre-die cutting line 23 is arranged in the middle of the separation belt 200, and when the pre-die cutting line 23 is opened and a channel opening 24 is formed, materials in different cavities are mixed through the channel opening 24.

The present embodiment is different from embodiment 1 in that the channel portion 26 of the separator 200 is provided with three sheets of the seal sheet including two sheets of the first seal sheet 21 and one sheet of the second seal sheet 22. The first sealing piece 21 is respectively arranged on the upper side and the lower side of the second sealing piece 22. The first and second sealing sheets 21 and 22 are tightly connected.

Similarly, in this embodiment, the separator 200 is a sheet structure and is integrally formed by a die-cutting process. The isolation belt 200 is used for being arranged in the middle of the packaging bag body 100 to separate the packaging bag body 100 into two different cavities, and the different cavities are not communicated with each other. When the separator 200 is required to be opened to connect different cavities, the split type packaging bag is folded to break the pre-cut lines between the different sealing sheets, and then the fixing part 25 applies force to the channel part 26 to enable the first sealing sheet 21 and the second sealing sheet 22 to bulge towards opposite directions, so that the different bag faces are separated, and a channel opening 24 is formed between the first sealing sheet 21 and the second sealing sheet 22 to complete the connection between the different cavities.

It should be noted that the same divided type packaging bag is not limited to only one separator 200 and two divided cavities, and the separator 200 is not limited to two or three seal sheets.

The foregoing is merely illustrative and explanatory of the utility model as it is described in more detail and is not thereby to be construed as limiting the scope of the utility model. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the spirit of the utility model, and that these obvious alternatives fall within the scope of the utility model.
