[0048] Example 1

[0049] See Figure 1-Figure 3 In this embodiment, a double-tube packaging container is provided, comprising a first tube 100, a second tube 200, and a discharge device 300. Both the first tube 100 and the second tube 200 are flexible tubes. For ease of description, the material stored in the first tube 100 is referred to as the first contents, and the material stored in the second tube 200 is referred to as the second contents.

[0050] The first tube body 100, the second tube body 200 and the discharge device 300 constitute the main body of the double-tube packaging container. Figure 1 In the embodiment, the main body and the cover 400 are in a separated state.

[0051] The first tube body 100 includes a first discharge head 110, and the second tube body 200 includes a second discharge head 210, wherein the first discharge head 110 and the second discharge head 210 are both connected to the discharge device 300. Since the first discharge head 110 and the second discharge head 210 are both connected to the discharge device 300, the first tube body 100 and the second tube body 200 are indirectly connected, making it convenient for users to carry.

[0052] like Figure 4 and Figure 5 As shown, the first tube body 100 includes a first outer side surface 120, and the second tube body 200 includes a second outer side surface 220. After assembly, the first outer side surface 120 and the second outer side surface 220 are arranged opposite to each other, and at least part of the positions of the two are in contact with each other, wherein the first tube body 100 and the second tube body 200 are arranged side by side. The first outer side surface 120 and the second outer side surface 220 can both be flat surfaces, and the two can be completely in contact with each other. It should be noted that Figure 4 Only the first discharge head 110 is cross-sectioned. Figure 5 In the figure, only the second discharge head 210 is cross-sectionally processed.

[0053] Reference Figure 4-Figure 7The shoulder of the first tube body 100 and the shoulder of the second tube body 200 both have an arcuate cross section. The chord side of the shoulder of the first tube body 100 and the chord side of the shoulder of the second tube body 200 are arranged relative to each other. Figure 4 In FIG, the portion indicated by arrow x is the shoulder of the first tube 100; Figure 5 In FIG, the portion indicated by arrow y is the shoulder of the second tube 200; Figure 6 In FIG, the portion indicated by arrow p is the chord side of the shoulder of the first tube body 100; Figure 7 In FIG, the portion indicated by arrow q is the chord side of the shoulder of the second tube body 200 .

[0054] In this embodiment, the cross-sections of the shoulder of the first tube 100 and the shoulder of the second tube 200 are both semicircular, and their radii can be comparable (including identical or similar). When assembled, the shoulder of the first tube 100 and the shoulder of the second tube 200 are spliced together to form a nearly complete circular structure.

[0055] The first discharge head 110 is provided with a first discharge hole 111, the second discharge head 210 is provided with a second discharge hole 211, and the discharge device 300 is provided with a first discharge channel 321 and a second discharge channel 322 arranged side by side. The first discharge hole 111 is connected to the first discharge channel 321, and the second discharge hole 211 is connected to the second discharge channel 322.

[0056] Reference Figure 8 and Figure 9 From the bottom to the top, the cross-sectional areas of the first discharge channel 321 and the second discharge channel 322 gradually decrease. This structure has the following advantages:

[0057] It is convenient for the first content to flow into the first discharge channel 321 and the second content to flow into the second discharge channel 322 ; and it is possible to effectively control the discharge amounts of the first content and the second content.

[0058] Reference Figure 8 and Figure 9 In the vertical direction, the uppermost part of the first discharge channel 321 and the second discharge channel 322 is the top of the channel, and the lowermost part is the bottom of the channel. Figure 8 All relevant parts are cross-sectioned.

[0059] like Figure 9 As shown, in this embodiment, a partition 323 is provided between the first discharge channel 321 and the second discharge channel 322 , and the first discharge channel 321 and the second discharge channel 322 are located on both sides of the partition 323 in the thickness direction.

[0060] The first discharge channel 321 includes a first discharge opening 3211, and the second discharge channel 322 includes a second discharge opening 3221. The top of the partition 323 is located between the first discharge opening 3211 and the second discharge opening 3221. The thickness of the top of the partition 323 is less than 4 mm. For example, the thickness of the top of the partition 323 is 3.9 mm, 3.7 mm, 3 mm, 2.7 mm, 2 mm, 2.3 mm, or 1 mm.

[0061] Figure 9 , the portion indicated by arrow a represents the top end of the partition 323 .

[0062] During use, the user can squeeze the first tube body 100 and the second tube body 200 with one hand or both hands at the same time. The first content in the first tube body 100 passes through the first discharge hole 111 and the first discharge channel 321 in sequence and is discharged from the first discharge port 3211; the second content in the second tube body 200 passes through the second discharge hole 211 and the second discharge channel 322 in sequence and is discharged from the second discharge port 322.

[0063] The top of the partition 323 is located between the first discharge port 3211 and the second discharge port 3221. The thickness of the top of the partition is less than 4 mm, thereby reducing the distance between the first and second discharge ports. As a result, when the first contents of the first tube 100 and the second contents of the second tube 200 are discharged from the first discharge port 3211 and the second discharge port 3221, respectively, the first and second contents can be quickly combined at the top of the partition 323, facilitating mixing and use.

[0064] In some embodiments, the thickness of the partition 323 may remain consistent from the top end to the tail end of the partition 323 , that is, the thickness of the partition 323 is less than 4 mm at any position of the partition 323 .

[0065] like Figure 10 As shown, in this embodiment, the cross section of the partition 323 includes a linear structure.

[0066] like Figure 11 As shown, in some other embodiments, the cross-section of the partition 323 includes a curved structure, wherein the curved structure includes a first arc segment 3231 and a second arc segment 3232 connected to each other, and the first arc segment 3231 and the second arc segment 3232 are centrally symmetrically arranged. The first arc segment 3231 and the second arc segment 3232 can be an integrated structure. For ease of observation, the connection between the first arc segment 3231 and the second arc segment 3232 is indicated by a dotted line in the figure. The dotted line is only a reference line and does not exist in the actual product.
