The packaging hose combines portability, durability and good sealing performance, and is particularly suitable for liquid or semi-solid products that need to be frequently opened and used. For packaging hoses, barrier property is a crucial performance index, especially in application scenarios where it is necessary to protect the contents from the external environment. The barrier property refers to the ability of the packaging material to prevent the penetration of gases (such as oxygen, water vapor) and other pollutants, which helps to maintain the quality of the product, prevent pollution, maintain the effectiveness of fragrance and active ingredients, and also improve the overall performance of the packaging.

[0003] However, in the prior art, packaging hoses usually incorporate barrier materials inside the tube body and tube shoulder to increase the overall barrier property. The opening of the tube shoulder (the top paste outlet) is usually sealed with a sealing sticker. Since the sealing sticker is adhered to the opening, there is a risk of loosening due to various reasons such as high temperature, resulting in a decrease in sealing performance. Moreover, the sealing sticker cannot completely cover the entire pipe orifice, and there will be a certain gap between the sealing sticker and the barrier layer contained in the opening, and this part cannot play a barrier role, thus affecting the overall barrier performance.

It should be noted that these embodiments are not limitations on the present utility model, and any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art according to these embodiments shall fall within the protection scope of the present utility model.

[0030] Embodiment 1:

[0031] Please refer Figures 1 to 5 to a specific embodiment of a hose barrier structure disclosed.

[0032] Refer Figure 1 to Figure 2 As shown, in this embodiment, the hose barrier structure 10 includes: a pipe shoulder 2 forming a pipe orifice 25, and the pipe shoulder 2 includes a filling shoulder 23, a barrier layer 22, and a lining 21 that are connected in sequence; wherein, the lining 21 includes a lining body 210 and a first connecting portion 211 extending radially from the bottom of the lining body 210 towards the filling shoulder 23, and the end face of the first connecting portion 211 close to the filling shoulder 23 is adhesively connected to the filling shoulder 23; the barrier layer 22 is clamped between the lining body 210 and the filling shoulder 23 and seals the pipe orifice 25, and the bottom of the barrier layer 22 abuts against the first connecting portion 211.

[0033] In this embodiment, the end face of the first connecting portion 211 close to the filling shoulder 23 is adhesively connected to the filling shoulder 23, the first connecting portion 211 is closely adhered to the filling shoulder 23, and the bottom of the barrier layer 22 abuts against the first connecting portion 211. The first connecting portion 211 can play a positioning role for the barrier layer 22, preventing the barrier layer 22 from shifting on the lining 21, so that the barrier layer 22 is accurately positioned between the lining body 210 and the filling shoulder 23 and fixed in place, so that the barrier layer 22 can be stably clamped between the lining 21 and the filling shoulder 23, avoiding the loosening of the sealing film adhered to the pipe orifice 25 in the original process due to various reasons such as high temperature. And the barrier layer 22 completely covers the entire pipe orifice 25 and is closely adhered to the pipe orifice 25, solving the problem in the prior art that there is a gap between the sealing film and the barrier layer 22 of the pipe shoulder where the pipe orifice is located, resulting in the inability of some pipe shoulders 2 to play a barrier role, ensuring the full barrier effect of the pipe shoulder 2, and enhancing the sealing performance of the pipe orifice 25.

[0034] In this embodiment, preferably, the barrier layer 22 is made of a flexible high-barrier material. The flexible high-barrier material includes: aluminum foil, aluminized composite film, polyvinylidene chloride coated film, and ethylene-vinyl alcohol copolymer coextruded film. The barrier layer 22 covers the entire pipe opening 25 to seal the pipe opening 25, thereby ensuring that the contents inside the hose barrier structure 10 are not affected by the external environment, preventing the penetration of oxygen, moisture, light, and other gases, and prolonging the shelf life of the contents.

[0035] In this embodiment, referring Figure 1 to Figure 2 as shown, the barrier layer 22 is configured with a first pipe opening portion 221 for sealing the pipe opening 25 and a first fan-shaped portion 222 disposed at the lower end of the first pipe opening portion 221 and integrally formed with the first pipe opening portion 221. The bottom of the first fan-shaped portion 222 abuts against the first connecting portion 211. The first pipe opening portion 221 covers the entire pipe opening 25 to ensure that the pipe opening 25 is completely closed, preventing external substances from entering the pipe and also preventing the leakage of the contents. The bottom of the first fan-shaped portion 222 abuts against the first connecting portion 211 to ensure the stable positioning and tight fitting of the barrier layer 22 between the inner liner body 210 and the injection shoulder 23. The first pipe opening portion 221 and the first fan-shaped portion 222 are integrally formed, enhancing the overall structural stability of the barrier layer 22, and by using a flexible high-barrier material, the full-barrier performance of the pipe shoulder 2 is ensured.

[0036] In this embodiment, referring Figure 2 to Figure 3 as shown, the first pipe opening portion 221 includes a connecting portion 2211 connected to the first fan-shaped portion 222 and a sealing portion 2212 connected to the connecting portion 2211 and sealing the pipe opening 25. A first arc-shaped connecting portion 2213 is formed at the connection between the sealing portion 2212 and the connecting portion 2211. By sealing the pipe opening 25 with the sealing portion 2212, it is ensured that the pipe opening 25 is completely closed, and the gap existing between the sealing film and the pipe opening in the prior art is eliminated. And the first fan-shaped portion 222 is connected through the connecting portion 2211, enabling the pipe shoulder 2 to play a full-barrier role. The first arc-shaped connecting portion 2213 is formed at the connection between the sealing portion 2212 and the connecting portion 2211, making the connection between the sealing portion 2212 and the connecting portion 2211 smoother, reducing stress concentration, and preventing the flexible barrier layer 22 from being damaged.

[0037] In this embodiment, referring Figure 2 to Figure 3As shown, the inner liner body 210 is configured with a second pipe orifice portion 213 and a second sector portion 214 disposed at the lower end of the second pipe orifice portion 213 and integrally formed with the second pipe orifice portion 213; a first connecting portion 211 is formed at the bottom of the second sector portion 214; the injection shoulder 23 is configured with a third pipe orifice portion 233 forming the pipe orifice 25 and a third sector portion 234 disposed at the lower end of the third pipe orifice portion 233 and integrally formed with the third pipe orifice portion 233; the first pipe orifice portion 221 is clamped between the third pipe orifice portion 233 and the second pipe orifice portion 213. The second sector portion 214 and the second pipe orifice portion 213 are integrally formed, enhancing the overall structural stability of the inner liner body 210.

[0038] The third sector portion 234 and the third pipe orifice portion 233 are integrally formed, enhancing the overall structural stability of the injection shoulder 23 and making the connection between the barrier layer 22 and the inner liner body 210 more firm, reducing the structural failure caused by insecure connection. Through the close fit between the first pipe orifice portion 221 and the second pipe orifice portion 213 and the third pipe orifice portion 233, and the close fit between the first sector portion 222 and the second sector portion 214 and the third sector portion 234, the first pipe orifice portion 221 is stably clamped between the third pipe orifice portion 233 and the second pipe orifice portion 213, making the connection between the barrier layer 22 and the inner liner body 210 and the injection shoulder 23 more tight, thereby enhancing the sealing performance at the pipe orifice 25, ensuring that the pipe orifice 25 is completely closed, reducing the risk of content leakage, ensuring the effective function of the barrier layer 22, and preventing problems such as oxygen penetration, moisture migration, microbial intrusion, and fragrance volatilization.

[0039] In this embodiment, referring Figure 2 to Figure 3 As shown, the second pipe orifice portion 213 is configured with a second arc-shaped connecting portion 2131 that fits and connects to the inner wall of the first arc-shaped connecting portion 2213, and the third pipe orifice portion 233 is configured with a third arc-shaped connecting portion 2331 that fits and connects to the outer wall of the first arc-shaped connecting portion 2213. Through the second arc-shaped connecting portion 2131 and the third arc-shaped connecting portion 2331, the connections between the second pipe orifice portion 213 and the third pipe orifice portion 233 and the first arc-shaped connecting portion 2213 are made smoother, avoiding the possible cutting damage to the flexible barrier layer 22 caused by the right-angled sharp connections of the second pipe orifice portion 213 and the third pipe orifice portion 233, which may damage the integrity of the barrier layer 22, resulting in a decrease in the barrier effect or even failure. Therefore, by constructing the second arc-shaped connecting portion 2131 and the third arc-shaped connecting portion 2331, the above situation is avoided, ensuring the integrity and barrier effect of the barrier layer 22.

[0040] In this embodiment, referring Figure 1 to Figure 2As shown, the hose barrier structure 10 further includes: a tube body 1 connecting to the shoulder 2; one end of the tube body 1 connecting to the shoulder 2 is bent inward to form a bent portion 11 covering at least a part of the shoulder 2, and the bent portion 11 covers the injection shoulder 23. The bent portion 11 is a covering structure formed by bending one end of the tube body 1 connecting to the shoulder 2 inward. By covering at least a part of the injection shoulder 23 with the bent portion 11, the connection strength and sealing performance between the shoulder 2 and the tube body 1 are enhanced.

[0041] In this embodiment, referring Figure 1 to Figure 2 As shown, the end face of the first connecting portion 211 away from the inner lining body 210 is in fitting connection with the inner wall of the tube body 1. The bottom of the inner lining body 210 extends in a direction away from the first connecting portion 211 to form a second connecting portion 212, and the end face of the second connecting portion 212 away from the inner lining body 210 is in fitting connection with the inner wall of the tube body 1. During the assembly process of the tube body 1 and the shoulder 2, the inner lining body 210 can be accurately positioned and fitted with the inner wall of the tube body 1 through the first connecting portion 211, enhancing the connection strength and sealing performance of the connecting portion between the shoulder 2 and the tube body 1, reducing leakage, cracking or other quality problems caused by the insecure connection between the shoulder 2 and the tube body 1, thus significantly extending the shelf life of the packaged contents and reducing the risk of product deterioration due to external environmental factors.

[0042] In this embodiment, preferably, after the inner lining 21 and the barrier layer 22 are connected and fixed, the inner lining 21, the barrier layer 22 and the tube body 1 are put into an injection shoulder machine (not shown) together, and the injection shoulder 23 is formed by injection molding process, and the injection shoulder 23 is assembled and formed with the inner lining 21 and the barrier layer 22 to form the shoulder 2, and at the same time, the shoulder 2 and a part of the tube body 1 are injection molded into one body. Moreover, during the process of connecting the inner lining 21 and the tube body 1, the first connecting portion 211 not only is in fitting connection with the inner wall of the tube body 1, but also abuts against the bent portion 11 of the tube body 1. Through the abutting action between the first connecting portion 211 and the bent portion 11, enough space is left for forming the injection shoulder 23 during the injection molding process between the barrier layer 22 and the bent portion 11, ensuring the accurate molding of the injection shoulder 23. And the position of the injection shoulder 23 can be effectively supported by the first connecting portion 211, ensuring that the injection shoulder 23 can be accurately positioned and form a good fit with the bent portion 11 of the tube body 1 during injection molding, and ensuring the neat appearance of the finished product.

[0043] The outer wall of the shoulder 23 is recessed inward to form a fitting groove 236 adapted to fit the bent portion 11. When the bent portion 11 is wrapped in the fitting groove 236, the outer wall of the bent portion 11 and the outer wall of the shoulder 23 are on the same plane. When the bent portion 11 is wrapped in the fitting groove 236, the tight fit between the bent portion 11 and the shoulder 23 is ensured through the fitting groove 236, thereby enhancing the sealing performance at the connection between the bent portion 11 and the shoulder 23. Moreover, since the outer wall of the bent portion 11 and the outer wall of the shoulder 23 are on the same plane, the connection between the pipe shoulder 2 and the pipe body 1 is more firm, which is conducive to the stable fitting of the bent portion 11 on the shoulder 23, enhancing the stability of the overall structure, reducing cracking or other quality problems caused by unstable connection, and making the overall appearance of the hose barrier structure 10 more flat, improving the aesthetics of the product. And it is easy to assemble. Through the fitting groove 236, the bent portion 11 can be more easily fitted and wrapped with the shoulder 23, simplifying the assembly process and improving the production efficiency. The fitting groove 236 is formed by the inward recess of the outer wall of the third sector portion 234, and the bent portion 11 is wrapped in the fitting groove 236 to ensure the tight fit between the bent portion 11 and the shoulder 23.

[0044] In the present embodiment, referring Figures 2 to 4 as shown, the second pipe orifice portion 213 protrudes radially outward to form at least two groups of parallel first protrusion portions 215, and a first card slot 216 is formed between adjacent first protrusion portions 215. The first pipe orifice portion 221 is configured with a second protrusion portion 223 corresponding to and engaging with the first card slot 216. By rotating the barrier layer 22, the second protrusion portion 223 on the first pipe orifice portion 221 is clamped and fixed in the first card slot 216 between adjacent first protrusion portions 215 to improve the connection stability between the barrier layer 22 and the inner liner body 210. And during the shoulder injection process, only by mechanically lifting the barrier layer 22 can the entire pipe body 1, inner liner 21 and barrier layer 22 to be shoulder-injected be grabbed and transferred, facilitating automated processing.

[0045] In other embodiments, the connection method between the bent portion 11 and the shoulder 23 can also be selected according to actual situations. For example, one end of the shoulder 23 close to the bent portion 11 is recessed inward to form a receiving groove (not shown), and the entire bent portion 11 is wrapped into the receiving groove, which can also play a connecting role while ensuring the flat and beautiful appearance of the whole. As long as the actual requirements can be met, the connection method between the bent portion 11 and the shoulder 23 is not specifically limited herein.

[0046] Exemplarily, in some embodiments, referring Figure 5As shown, the first pipe orifice 221 protrudes radially inward to form at least two groups of second protrusions 223 arranged in parallel. A second card slot 224 is formed between adjacent second protrusions 223. The second pipe orifice 213 is configured with a first protrusion 215 corresponding to the second card slot 224 and inserted into the second card slot 224. By rotating the barrier layer 22, adjacent two groups of second protrusions 223 on the first pipe orifice 221 are clamped and fixed outside the first protrusion 215, and the first protrusion 215 is inserted into the second card slot 224 to improve the connection stability between the barrier layer 22 and the inner lining body 210.

[0047] Embodiment 2:

[0048] Based on the technical solution of a hose barrier structure disclosed in the foregoing Embodiment 1, the present application also discloses a cap.

[0049] In this embodiment, referring to Figure 7 As shown, the cap 30 includes the hose barrier structure 10 disclosed in the foregoing Embodiment 1, and the cap 30 forms a detachable connection with the hose barrier structure 10. The cap 30 is used to close the pipe orifice 25, protect the pipe orifice 25 from pollution, prevent external pollutants such as dust and impurities from entering the inside of the hose barrier structure 10, and can conveniently open and close the pipe orifice 25 during use.

[0050] In this embodiment, referring to Figure 3 As shown, an external thread 235 is configured on the outer periphery of the third pipe orifice 233. By mating the external thread 235 with an internal thread (not marked) of the cap 30, the opening and closing of the pipe orifice 25 are facilitated. In other embodiments, other detachable connection methods such as snap connection or plug-in connection can also be selected. Here, the detachable connection method between the hose barrier structure 10 and the cap 30 is not specifically limited.

[0051] In this embodiment, referring to Figure 7 As shown, a cone 31 corresponding to the pipe orifice 25 included in the hose barrier structure 10 is recessed on the side of the cap 30 opposite to the hose barrier structure 10. Since the barrier layer 22 is made of a soft high-barrier material, the barrier layer 22 at the pipe orifice 25 can be punctured through the cone 31 so as to open the pipe orifice 25 during the first use. The entire cone 31 is recessed into the top of the cap 30 to prevent injury to the user. An advertising label can also be pasted above the cone 31, which plays an advertising role while hiding the cone 31 to ensure the appearance is beautiful. In other embodiments, structures such as a card board or a screw cap can also be selected to hide the cone 31.

[0052] Embodiment 3:

[0053] Based on the technical solution of a cap disclosed in the foregoing Embodiment 2, this embodiment also discloses a hose.

[0054] In this embodiment, refer to Figure 8 As shown, the hose 100 includes a tube body 40 and a cap 30 disposed on the tube body 40 as disclosed in the above embodiment. The cap 30 is used to seal the nozzle 25 of the tube body 40, prevent the leakage of the contents, and protect the nozzle 25 from contamination. The cap 30 is connected to the tube body 40 by a detachable connection method, which facilitates the opening and closing of the nozzle 25. The tube body 40 achieves a full barrier effect through the hose barrier structure 10, ensuring that the entire hose 100 has excellent barrier properties, thereby effectively preventing problems such as oxygen penetration, moisture migration, microbial intrusion, and fragrance volatilization, and significantly improving the shelf life and safety of the packaged contents. Moreover, the barrier layer 22 is closely attached to the nozzle 25, enhancing the sealing performance at the nozzle 25 and reducing the risk of content leakage.

[0055] Exemplarily, in some embodiments, refer to Figure 6 As shown, the hose 100 further includes a check valve 24 disposed inside the second nozzle portion 213 and corresponding to the nozzle 25. The opening direction of the check valve 24 faces the nozzle 25. When the user uses it, by squeezing the tube body 40, the internal pressure of the hose 100 increases, and the contents in the tube body 40 squeeze the check valve 24. The check valve 24 opens its opening under the action of the pressure, so that the contents can be extruded through the nozzle 25. After releasing the tube body 40, the check valve 24 closes its opening under the action of the internal and external pressure difference. Furthermore, through the check valve 24, it is possible to prevent the contents from flowing back during the use of the hose 100, ensure that the contents can only flow out unidirectionally from the nozzle 25, prevent backflow pollution, and at the same time, after the barrier layer 22 is opened, the check valve 24 can continue to play the role of sealing and blocking, slow down the rates of oxygen penetration, moisture migration, microbial intrusion, and fragrance volatilization, extend the shelf life of the contents, and reduce the risk of product deterioration caused by external environmental factors.
