[0006] As a preferred option, a cap is also included, which is placed over the upper part of the outer hose to seal the inner tube outlet and the outer tube outlet.

[0007] Preferably, the upper part of the outer flexible tube has a tapered constriction structure, and the outer edge forms a retaining structure for installing a seat cap.

[0008] Preferably, a snap-fit ​​area and a channel area are provided between the conical ends of the inner and outer hoses, and the inner hose has at least two sides recessed towards the center to form the channel area; the snap-fit ​​area is a snap groove and snap ridge provided on the contact surface of the inner and outer hoses.

[0009] Preferably, the upper part of the cap is also provided with a bushing, the upper part of the bushing is provided with a groove cavity, and a brush head cap is placed in the groove cavity. The brush head cap is fitted into the groove cavity for applying / massaging the skin.

[0010] As a preferred option, a protective cover is also included, which is fitted onto the seat cap to protect the brush head cap.

[0011] Preferably, the outer tube has three outlets, which are evenly distributed.

[0012] The beneficial effects of this utility model are: the tube-in-tube double-lumen flexible tube packaging bottle of this utility model can squeeze out two different cosmetic pastes at the same time when in use. It has a brush head cap and a protective cover, which can be used conveniently, avoiding manual application of cosmetics and waste of cosmetic materials. After use, it can be quickly installed and reset. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] like Figure 1-3The illustrated tube-in-tube double-lumen flexible tube packaging bottle consists of an inner flexible tube 1 and an outer flexible tube 2, forming a double-layer structure that creates an inner cavity 11 and a peripheral cavity 21, respectively. It can be filled with two types of cosmetic lotions / creams, allowing the user to simultaneously squeeze out two different products. During use, two substances of different properties or colors can be extruded simultaneously to create shaped patterns, enhancing the visual appeal of the products.

[0023] The inner hose 1 and the outer hose 2 each have connecting parts at their upper and lower ends, forming a stable structure. The upper part of the inner hose 1 has an inner tube outlet 12. The circumferential edge of the outer hose 2 connects to the edge of the inner tube outlet 12. The circumferential edge of the outer hose 2 extends towards the center to form a planar structure, on which at least one outer tube outlet 22 is provided. In this embodiment, there are three outer tube outlets 22, which are circular groove-shaped structures, evenly distributed, enabling the extrusion of shaped patterns and enhancing the visual effect of the material.

[0024] See Figure 2 , 3 The cap 3 is placed on the upper part of the outer tube 2 to seal the inner tube outlet 12 and the outer tube outlet 22. Since the upper end of the outer tube 2 is a flat structure, it is easy to maintain the sealing effect and protect the cosmetic lotion inside.

[0025] See Figure 3 , 4 The upper part of the outer flexible hose 2 has a tapered constriction structure, and the outer edge forms a retaining structure 23 for mounting the cap 3. The upper part of the outer flexible hose 2 is stepped, and the outer edge of the retaining structure 23 has a threaded structure. The cap 3 is threadedly screwed onto the retaining structure 23.

[0026] See Figure 5 A snap-fit ​​area and a channel area 25 are provided between the conical ends of the inner hose 1 and the outer hose 2. The inner hose 1 has at least two sides recessed towards the center to form the channel area 25. The snap-fit ​​area consists of a snap groove 13 and a snap ridge 24 on the contact surface between the inner hose 1 and the outer hose 2, and its structure is stable.

[0027] See Figure 2 , 3 The upper part of the cap 3 is also provided with a bushing 6, and the upper part of the bushing 6 is provided with a groove cavity 31. The brush head cap 4 is placed in the groove cavity 31 and fits smoothly into the groove cavity 31 for applying / massaging the skin. It is convenient to use, avoids manual application of cosmetics and the waste of cosmetics, and can be quickly installed and reset after use. The brush head cap 4 is made of silicone or sponge.

[0028] See Figure 2 , 3 The upper part of the cap 3 is a mounting bracket structure that fits the bushing 6 and is used to install the bushing 6.

[0029] See Figure 1 The cap 3 also has a protective cover 5, which is fitted onto the cap 3 to protect the brush head cap 4.

[0030] The tube-in-tube double-lumen flexible tube packaging bottle of this utility model can simultaneously squeeze out two different cosmetic pastes. It has a brush head cap 4 and a protective cover 5, which can be used conveniently, avoiding manual application of cosmetics and waste of cosmetic materials. After use, it can be quickly installed and reset.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
