[0001] The utility model relates to the technical field of beauty or medicine, and in particular to a packaging bag structure. Background Art

[0002] In the field of beauty or medicine, in order to prevent different functional substances from losing their activity during long-term mixed storage, different functional substances need to be packaged separately and then mixed when needed to achieve the best effect.

[0003] The traditional packaging method is to use multiple packaging bags to package different functional substances separately, and then mix them when they need to be used. However, when mixing, all the functional substances in other packaging bags need to be poured into one packaging bag, or additional containers are needed to hold these functional substances, which is inconvenient to operate or costly. In this regard, there is also a multi-chamber packaging bag in the prior art, where multiple chambers are virtual sealed. When they need to be mixed and used, the virtual seal is destroyed by squeezing to achieve mixing of the objects in each chamber. However, this structure has high requirements for the virtual seal. If the virtual seal is too solid, it will be difficult to squeeze it open. If the virtual seal is too loose, the chambers may leak from each other at the virtual seal. Utility Model Content

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0035] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0036] like Figure 1 As shown, the utility model provides a packaging bag structure, which includes a first bag body 1 and a second bag body 2. Different objects can be stored in the first bag body 1 and the second bag body 2 respectively. For example, liquid functional substances can be stored in one of the bag bodies, and solid functional substances or freeze-dried facial masks and other film fabrics can be stored in the other bag body; or liquid functional substances can be stored in both bag bodies.

[0037] Furthermore, a connecting cavity 3 is provided between the first bag body 1 and the second bag body 2, and the connecting cavity 3 is sealed and connected with the bag surfaces of the first bag body 1 and the second bag body 2, and the whole is formed into a sealed cavity. A bag breaking structure 4 is provided in the connecting cavity 3, and the bag breaking structure 4 includes at least one puncture piece 41. In the initial state, the puncture end of the puncture piece 41 is engaged, that is, the puncture end is fixed so that it cannot directly face the first bag body 1 or the second bag body 2, for example, it is coated, fixedly connected with the side wall of the connecting cavity 3, or connected with the puncture ends of other puncture pieces, etc., so that the puncture end cannot contact the first bag body 1 and the second bag body 2, and will not puncture any bag body; and when in use, the puncture piece 41 can be subjected to force to break its engagement, for example, removing the coating, releasing the fixed connection with the connecting cavity 3 or other puncture pieces, so that the puncture end can face the first bag body 1 and the second bag body 2, and can puncture the first bag body 1 and the second bag body 2.

[0038] Preferably, the piercing end of the piercing sheet 41 is serrated, so that each bag can be pierced over a larger area, so that the objects in each bag can be mixed faster and more fully.

[0039] The bag breaking structure 4 is described in detail below through several embodiments.

[0040] Embodiment 1:

[0041] like Figure 2-3 As shown, the bag breaking structure 4 of this embodiment includes a puncture piece 41, and the puncture end of the puncture piece 41 is fixed by a joint piece 411. Specifically, the puncture end of the puncture piece 41 can be connected to the joint piece 411 through a tiny connecting strip 46. The connecting strip 46 can be set at the tip of the sawtooth and can be connected by welding or the like. The joint piece 411 is a square piece or other shapes. In the initial state, the puncture end of the puncture piece 41 is connected to the joint piece 411, so that the puncture end cannot puncture toward any bag body. When it is needed to be used, an external force destroys the connection between the two, so that the puncture end of the puncture piece 41 can first puncture toward the first bag body 1, and then puncture toward the second bag body 2, so that the objects in the two bags can be mixed. In addition, a tear can be set on any bag body to tear it open for use after mixing. The size and number of the connecting strip 46 can be set as needed, so that the puncture piece 41 can be joined when stored, and can be easily destroyed when needed. In other embodiments, the puncturing end of the puncturing piece 41 may also be fixed to the inner wall of the connecting cavity 3, or connected and joined with the puncturing end of another puncturing piece 41. The two opposite ends of the joining piece 411 and the puncturing piece 41 may be fixed to two opposite inner walls of the connecting cavity 3, respectively, or the joining piece 411 and the puncturing piece 41 may also be directly built into the connecting cavity 3.

[0042] Compared with the prior art, the packaging bag structure provided in this embodiment can store two different functional substances at the same time. Since the two bag bodies remain sealed before use, there is no leakage problem. Moreover, when in use, the two bag bodies can be easily broken and mixed by twisting the bag bodies, and can be taken out after the mixing time is set. The operation is convenient and labor-saving, and the requirements for the material and production process of the bag body are relatively low, and the cost is low.

[0043] In addition, in this embodiment, the strength of the bag surface facing the connecting cavity 3 in the first bag body 1 and the second bag body 2 is set to be smaller than the strength of the bag surface away from, i.e., facing away from, the connecting cavity 3, that is, the strength of the outer bag surface of each bag body is greater than the strength of the inner bag surface. For example, the thickness of the outer bag surface is set to be greater than the thickness of the inner bag surface, or the outer bag surface is set to be a multi-layer structure including a reinforcement layer, etc., so as to prevent the outer bag surface from being punctured or scratched.

[0044] It can be seen from the above content that the packaging bag structure provided in this embodiment can achieve separate storage and mixed use. Its structure is reliable and will not cause leakage during storage. It is also very convenient to break the bag when mixed use is required.

[0045] Embodiment 2:

[0046] like Figure 4-6 As shown, the bag breaking structure 4 of this embodiment includes a plurality of puncturing pieces, specifically two puncturing pieces, the two puncturing pieces are connected in sequence, and the puncturing ends of the two puncturing pieces are arranged opposite to each other.

[0047] Specifically, the two puncture pieces are respectively a first puncture piece 42 and a second puncture piece 43. The first puncture piece 42 includes a first puncture end 421, and the second puncture piece 43 includes a second puncture end 431. The sawtooth tips of the first puncture end 421 and the second puncture end 431 are arranged opposite to each other. In the initial state, that is, during the storage process, the first puncture end 421 is engaged with the second puncture end 431, and the serrations of the first puncture end 421 are correspondingly inserted into the serration grooves of the second puncture end 431, and the serrations of the second puncture end 431 are also correspondingly inserted into the serration grooves of the first puncture end 421, and the two remain relatively fixed, and the two puncture pieces are parallel to the two bag surfaces, and the first puncture end 421 and the second puncture end 431 will not puncture or scratch any bag body; when mixed use is required, the engagement of the first puncture end 421 and the second puncture end 431 can be destroyed by applying force with the hand, so that the first puncture end 421 and the second puncture end 431 puncture the first bag body 1 and the second bag body 2 separately or together.

[0048] The first puncture piece 42 and the second puncture piece 43 can also be connected by a small connecting strip 46, which can be set between the saw teeth and can be connected by welding or other methods. The connecting strip 46 keeps the first puncture piece 42 and the second puncture piece 43 relatively fixed in the initial state, and can be easily destroyed when it is needed. The size and number of the connecting strip 46 can be set as needed. Alternatively, in other embodiments, the first puncture piece 42 and the second puncture piece 43 can be kept fixed in advance by bonding or other methods. In this embodiment, the root end of the first puncture piece 42 and the root end of the second puncture piece 43 can be fixedly connected to the middle of the left and right opposite side walls in the connecting cavity 3, respectively, and the connection method can be selected but not limited to welding; or the root ends of the first puncture piece 42 and the second puncture piece 43 can also be not connected to the inner wall of the connecting cavity 3, but directly placed in the connecting cavity 3.

[0049] For example, Figure 5 As shown, in the first bag breaking method, when in use, the first puncture sheet 42 and the second puncture sheet 43 are folded together in the same direction, for example, first folded toward the first bag body 1, so that the first bag body 1 is punctured first, and then the first puncture sheet 42 and the second puncture sheet 43 are folded together in the opposite direction, that is, folded toward the second bag body 2, so that the second bag body 2 is punctured, so that the functional substances in the first bag body 1 and the second bag body 2 can be mixed. Or, Figure 6 As shown, in the second bag breaking method, when in use, the first piercing piece 42 moves toward one bag body to pierce the bag body, and the second piercing piece 43 moves toward the other bag body to pierce the bag body, so that the functional substances in the two bags can also be mixed. A tearing notch can be set on either bag body so that it can be torn open for use after mixing.

[0050] In this way, the bag breaking structure 4 provided in this embodiment can be punctured by two puncturing pieces, which makes it easier to break the bag, and can be operated in two bag breaking ways, which is convenient to operate.

[0051] Embodiment three:

[0052] like Figure 7-8 As shown, compared with the second embodiment, the bag breaking structure 4 of this embodiment includes not only the first puncture piece 42 and the second puncture piece 43, but also the third puncture piece 44 and the fourth puncture piece 45, wherein the third puncture piece 44 includes a third puncture end 441, and the fourth puncture piece 45 includes a fourth puncture end 451.

[0053] In the initial state, the first puncture end 421 is engaged with the second puncture end 431, that is, the two are relatively fixed and will not puncture any bag body, and the third puncture end 441 is engaged with the fourth puncture end 451, that is, the two are relatively fixed and will not puncture any bag body; when mixed use is required, the engagement between the first puncture end 421 and the second puncture end 431 is destroyed, so that the first puncture end 421 and the second puncture end 431 move toward the first bag body 1 together to puncture the first bag body 1, and the engagement between the third puncture end 441 and the fourth puncture end 451 is destroyed, so that the third puncture end 441 and the fourth puncture end 451 move toward the second bag body 2 together to puncture the second bag body 2.

[0054] The root of each puncture piece 41 can be welded to the inner wall of the connecting cavity 3, and the four puncture pieces 41 are roughly formed into a parallelogram structure. In the initial state, the middle joint of the first puncture piece 42 and the second puncture piece 43 can be slightly arched upward, and the middle joint of the third puncture piece 44 and the fourth puncture piece 45 can be slightly arched downward. Each puncture end should be as small as possible. In this way, when applying force in the left and right directions during operation, the first puncture piece 42 and the second puncture piece 43 move upward to puncture the upper bag body, and the third puncture piece 44 and the fourth puncture piece 45 move downward to puncture the lower bag body. This structure is more convenient for bag breaking operation.

[0055] In order to make the movement of each puncture piece 41 more stable, the root end of the first puncture piece 42 is hinged with the root end of the third puncture piece 44 in this embodiment, and the two ends of the hinge axis are fixedly connected to the inner wall of the connecting cavity 3, and the positions close to the hinge axis on the two puncture pieces 41 need to be staggered and avoid each other with corresponding slots; the root end of the second puncture piece 43 is hinged with the root end of the fourth puncture piece 45, and the two ends of the hinge axis are fixedly connected to the inner wall of the connecting cavity 3, and the positions close to the hinge axis on the two puncture pieces 41 need to be staggered and avoid each other with corresponding slots. Further preferably, the middle part of the first puncture end 421 is hinged with the middle part of the second puncture end 431, that is, a hinge axis is set at the middle position of the length direction of the saw teeth of the two, and the middle part of the third puncture end 441 is hinged with the middle part of the fourth puncture end 451, that is, a hinge axis is set at the middle position of the length direction of the saw teeth of the two, so as to form a parallelogram mechanism, which has more stable movement and better bag breaking effect.

[0056] Similar to the second embodiment, in this embodiment, a connecting strip 46 can be provided between the first piercing end 421 and the second piercing end 431, so that the two remain relatively fixed during storage and can be easily broken during use; similarly, a connecting strip 46 is also provided between the third piercing end 441 and the fourth piercing end 451, so that the two remain relatively fixed during storage and can be easily broken during use. The size and number of the connecting strips 46 can be set as needed.

[0057] Embodiment 4:

[0058] like Figure 9-10 As shown, the bag breaking structure 4 of this embodiment includes a plurality of puncture pieces 41, specifically three, the three puncture pieces 41 are connected in sequence, and the puncture ends of the three puncture pieces 41 are connected to each other, specifically, the puncture end of the first puncture piece 41 and the first puncture end of the second puncture piece 41 can be connected through a connecting strip, and the second puncture end of the second puncture piece 41 and the puncture end of the third puncture piece 41 can be connected through a connecting strip. In the initial state, each puncture piece 41 will not puncture the first bag body 1 and the second bag body 2; when it is necessary to mix and use, twist the bag body to break the joint, so that each bag body is punctured. Compared with the previous embodiment, multiple locations of each bag body can be punctured, and mixing is faster.

[0059] Embodiment five:

[0060] The bag-breaking structure of this embodiment includes more puncturing pieces, that is, the number of puncturing pieces is four or more, similar to the fourth embodiment, these puncturing pieces are connected in sequence, and the puncturing ends of each puncturing piece are engaged with each other, and the first bag body 1 and the second bag body 2 will not be punctured in the initial state; when in use, the multiple puncturing pieces are subjected to force so that the engagement of the puncturing ends is destroyed, and the puncturing ends can puncture the first bag body 1 and the second bag body 2. In this way, more places of the two bag bodies can be punctured, achieving a better mixing effect.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
