[0023] Please refer to Figure 1-4 A double-layer isolation mother-and-child hose comprises a tube body and a cover body, the cover body is detachably connected to the tube body, the tube body comprises an outer tube body 1 and an inner tube body 2, both the outer tube body 1 and the inner tube body 2 are columnar hoses, the inner tube body 2 is arranged in the outer tube body 1, and a accommodating cavity 3 is formed between the outer tube body 1 and the inner tube body 2, one content is stored in the accommodating cavity 3, and one content is stored in the inner tube body 2, that is, two contents that can be used at the same time but cannot be stored together are respectively stored in the accommodating cavity 3 and the inner tube body 2, and the two are isolated by the inner tube body 2. An outer tube head 4 is provided at one end of the outer tube body 1, and an inner tube head 5 is provided at one end of the inner tube body 2. The inner tube head 5 is arranged in the outer tube head 4, but the outer wall of the inner tube head 5 is not tightly fitted with the inner wall of the outer tube head 4, and there is a certain gap between the two to facilitate the outflow of the contents in the accommodating chamber 3. A first discharge port 6 is provided at the middle position of the inner tube head 5, and a plurality of grooves 7 are provided on the outer periphery of the top of the inner tube head 5. A gap is formed between the grooves 7 and the outer tube head 4, and the gap is a second discharge port 8, that is, the second discharge port 8 is arranged around the first discharge port 6. By squeezing the tube body, under the action of force, the two contents will flow out from the accommodating chamber 3 and the inner tube body 2 through the second discharge port 8 and the first discharge port 6 respectively for use by consumers.
[0024] In this embodiment, the number of the grooves 7 is three, and the distance between the centers of two adjacent grooves 7 is 120°, that is, the number of the second discharge ports 8 is three.
[0025] In this embodiment, the cross section of the upper part of the outer tube head 4 is a regular decagon, and the outer wall of the lower part of the outer tube head 4 is provided with an external thread.
[0026] In this embodiment, after the contents are loaded into the outer tube body 1 and the inner tube body 2, the tail is sealed by ultrasonic welding, and the excess inner tube body 2 is removed.
[0027] In this embodiment, the outer tube body 1 is a mother tube, and the inner tube body 2 is a daughter tube.
[0028] Furthermore, an annular groove 9 is provided on the inner wall of the outer tube head 4, and two clamping blocks 10 are provided on the outer wall of the inner tube head 5. The clamping blocks 10 are clamped in the annular groove 9, so that the inner tube head 5 can be fixed in the outer tube head 4, that is, the inner tube is fixed in the outer tube. The angle occupied by the two clamping blocks 10 added together does not exceed one half of the full circle, so that a gap is formed between the outer tube head 4 and the inner tube head 5, which facilitates the discharge of the contents in the accommodating cavity 3.
[0029] Furthermore, a slope 11 is provided on the top of the clamping block 10 , and the design of the slope 11 facilitates the clamping block 10 to be inserted into the annular clamping groove 9 to form a snap fit.
[0030] Furthermore, a transition platform 12 is provided between the outer tube body 1 and the outer tube head 4. The outer tube body 1, the transition platform 12 and the outer tube head 4 are an integrated structure, which are integrally formed by injection molding.
[0031] Furthermore, the cover body includes an outer cover 13 and an inner ring 14. When the cover body is fully assembled on the tube body, the inner ring 14 will collide with the transition platform 12 to form a seal to prevent external air from entering the tube body and contaminating the contents. Eight equidistant and vertically distributed reinforcing ribs 15 are arranged on the side wall of the inner ring 14. The outer cover 13, the inner ring 14 and the reinforcing ribs 15 are an integrated structure and are cast by integral injection molding.
[0032] In this embodiment, an internal thread is provided on the inner wall of the inner ring 14, and the internal thread on the inner ring 14 is matched with the external thread on the outer pipe head 4, that is, the cover body can be detachably connected to the pipe body through the cooperation of the inside and the outside.
[0033] Furthermore, a protective film 16 is provided at the top of the inner ring 14. When the cover is fully assembled on the tube body, the protective film 16 will seal the two discharge ports to form a seal, thereby preventing external air from entering the tube body and contaminating the contents, and also preventing the contents from leaking.
[0034] Furthermore, the inner tube body 2 and the inner tube head 5 are an integrated structure, which are integrally formed by injection molding.
[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
