Description

Technical Field

[0001] The utility model relates to the technical field of hose assemblies, and particularly to a modular barrier structure for a hose shoulder and a hose. Background Art

[0002] In modern production and daily life, packaging hoses, as a common packaging form, are widely used in fields such as cosmetics, personal care products, food, pharmaceuticals, and industrial products. Packaging hoses combine portability, durability, and good sealing performance, and are 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. Barrier property refers to the ability of packaging materials to prevent the penetration of gases (such as oxygen, water vapor) and other pollutants, which helps to maintain the quality of products, prevent contamination, maintain the effectiveness of fragrances and active ingredients, and also improve the overall performance of the packaging.

[0003] However, in the prior art, packaging hoses are usually manufactured and assembled separately from two parts: a tube body and a tube shoulder. During the production process, although barrier materials are laminated into the tube body material, the subsequently assembled tube shoulder part still uses ordinary materials, thus lacking the necessary barrier property. This defect may lead to problems such as oxygen penetration, moisture transfer, microbial intrusion, and fragrance volatilization, thereby affecting the overall quality and shelf life of the products.

[0004] In view of this, it is necessary to improve the packaging hoses in the prior art to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to disclose a modular barrier structure for a hose shoulder and a hose, which is used to solve various defects existing in the packaging hoses in the prior art. In particular, it is to achieve the full barrier effect of the whole hose, ensure the tight fit between the tube shoulder and the tube body, and improve the connection strength and sealing performance between the tube shoulder and the tube body.

[0006] To achieve the above purpose, in the first aspect, the utility model provides a modular barrier structure for a hose shoulder, including a tube body and a tube shoulder connected to the tube body. The tube shoulder includes a filling shoulder, a barrier layer, and a lining connected in sequence. One end of the tube body connected to the tube shoulder is bent inward to form a bent portion that covers at least part of the tube shoulder. Wherein, the lining includes a lining body and a first connecting portion extending radially from the bottom of the lining body towards the filling shoulder. The end face of the first connecting portion away from the lining body is in fitting connection with the inner wall of the tube body, and the end face close to the filling shoulder is in fitting connection with the filling shoulder.

[0007] A receiving space is formed by enclosing between the inner lining body, the first connecting portion, and the injection shoulder. The barrier layer is fitted in the receiving space, and the bent portion is wrapped around the injection shoulder.

[0008] As a further improvement of the present utility model, a second connecting portion is formed by extending the bottom of the inner lining body in a direction away from the first connecting portion, and the end surface of the second connecting portion away from the inner lining body is in fitting connection with the inner wall of the pipe body.

[0009] As a further improvement of the present utility model, a fitting groove adapted for the bent portion to fit is formed by inwardly recessing the outer wall of the injection shoulder. When the bent portion is wrapped in the fitting groove, the outer wall of the bent portion is on the same plane as the outer wall of the injection shoulder.

[0010] As a further improvement of the present utility model, the barrier layer is configured with a first pipe orifice portion and a first sector portion disposed at the lower end of the first pipe orifice portion and integrally formed with the first pipe orifice portion;

[0011] The inner lining body is configured with a second pipe orifice portion and a second sector portion disposed at the lower end of the second pipe orifice portion and integrally formed with the second pipe orifice portion;

[0013] As a further improvement of the present utility model, the injection shoulder is configured with a pipe orifice platform that sequentially extends radially inwardly past the upper end of the first pipe orifice portion and the upper end of the second pipe orifice portion, and the pipe orifice platform forms a groove for clamping the upper end of the first pipe orifice portion and the upper end of the second pipe orifice portion.

[0014] As a further improvement of the present utility model, at least two sets of first protrusions are formed by protruding the second pipe orifice portion radially outwardly and arranged in parallel, and a first card slot is formed between adjacent first protrusions. The first pipe orifice portion is configured with a second protrusion corresponding to the first card slot and inserted into the first card slot.

[0015] As a further improvement of the present utility model, at least two sets of second protrusions are formed by protruding the first pipe orifice portion radially inwardly and arranged in parallel, and a second card slot is formed between adjacent second protrusions. The second pipe orifice portion is configured with a first protrusion corresponding to the second card slot and inserted into the second card slot.

[0016] As a further improvement of the present utility model, the injection shoulder is configured with a third pipe orifice portion and a third sector portion disposed at the lower end of the third pipe orifice portion and integrally formed with the third pipe orifice portion, and the pipe orifice platform extends radially inwardly from the third pipe orifice portion.

[0018] The bent portion at least partially surrounds the bottom of the shoulder and covers the third sector portion.

[0019] In a second aspect, the present utility model also provides a hose, comprising: a modular barrier structure for the hose shoulder as described in any one of the first aspects.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: By embedding the barrier layer into the accommodation space, it is ensured that the barrier layer is tightly combined with the inner liner, thereby enhancing the barrier performance of the shoulder, ensuring the full barrier effect between the shoulder and the body, thus significantly enhancing the overall barrier performance of the modular barrier structure for the hose shoulder, effectively preventing problems such as oxygen penetration, moisture migration, microbial invasion, and fragrance volatilization, and ensuring the quality of the packaged contents.

[0026] The present utility model will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. It should be noted, however, that these embodiments are not intended to limit the present utility model. Any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present utility model.

[0027] Please refer Figures 1 to 5 to a specific embodiment of a modular barrier structure for a hose shoulder and a hose disclosed herein.

[0028] Refer Figure 1 to Figure 2 As shown, in this embodiment, the modular barrier structure for the hose shoulder includes: a pipe body 1 and a pipe shoulder 2 connected to the pipe body 1. The pipe shoulder 2 includes a filling shoulder 23, a barrier layer 22, and a lining 21 that are connected in sequence. One end of the pipe body 1 connected to the pipe shoulder 2 is bent inward to form a bent portion 11 that covers at least a part of the pipe shoulder 2.

[0029] Among them, the lining 21 includes a lining body 210 and a first connecting portion 211 that extends radially from the bottom of the lining body 210 toward the filling shoulder 23. The end face of the first connecting portion 211 away from the lining body 210 is in close connection with the inner wall of the pipe body 1, and the end face close to the filling shoulder 23 is in close connection with the filling shoulder 23. A receiving space 217 is formed by enclosing the lining body 210, the first connecting portion 211, and the filling shoulder 23. The barrier layer 22 is fitted into the receiving space 217, and the bent portion 11 covers the filling shoulder 23.

[0030] In this embodiment, by inserting the lining 21 (including the lining body 210 and the first connecting portion 211) into the inside of the pipe body 1, connecting the filling shoulder 23 with the first connecting portion 211, making the end face of the first connecting portion 211 fit with the inner wall of the pipe body 1, and embedding the barrier layer 22 into the receiving space 217 formed by the lining body 210, the first connecting portion 211, and the filling shoulder 23, it is ensured that the barrier layer 22 is tightly combined with the lining 21 and the filling shoulder 23. The bent portion 11 is a covering structure formed by bending one end of the pipe body 1 connected to the pipe shoulder 2 inward. By covering at least a part of the filling shoulder 23 with the bent portion 11, the connection strength and sealing performance between the pipe shoulder 2 and the pipe body 1 are enhanced.

[0031] It is embedded into the accommodation space 217 through the barrier layer 22 to ensure the tight combination of the barrier layer 22 and the inner liner 21, thereby enhancing the barrier performance of the pipe shoulder 2, ensuring the full barrier effect between the pipe shoulder 2 and the pipe body 1, thus significantly enhancing the overall barrier performance of the modular barrier structure for the hose shoulder, effectively preventing problems such as oxygen penetration, moisture migration, microbial invasion, and fragrance volatilization, and ensuring the quality of the packaged contents. And the first connection part 211 of the inner liner 21 is adhesively connected to the inner wall of the pipe body 1, enhancing the connection strength and sealing performance of the connection part between the pipe shoulder 2 and the pipe body 1, reducing leakage, cracking or other quality problems caused by the insecure connection between the pipe shoulder 2 and the pipe body 1, thereby significantly extending the shelf life of the packaged contents and reducing the risk of product deterioration caused by external environmental factors.

[0032] In this embodiment, preferably, after the inner liner 21 and the barrier layer 22 are connected and fixed, the inner liner 21, the barrier layer 22, and the pipe body 1 are put into a shoulder injection machine (not shown) together, and the shoulder 23 is injected by an injection molding process, and the shoulder 23 is assembled and formed with the inner liner 21 and the barrier layer 22 to form the pipe shoulder 2, and at the same time, the pipe shoulder 2 and a part of the pipe body 1 are injection molded into one body. And, during the process of connecting the inner liner 21 and the pipe body 1, the first connection part 211 not only is adhesively connected to the inner wall of the pipe body 1, but also abuts against the bent part 11 of the pipe body 1. Through the abutting action between the first connection part 211 and the bent part 11, enough space is left between the barrier layer 22 and the bent part 11 for forming the shoulder 23 during the injection molding process, ensuring the accurate molding of the shoulder 23. And the position of the shoulder 23 can be effectively supported by the first connection part 211, ensuring that the shoulder 23 can be accurately positioned during injection molding and form a good fit with the bent part 11 of the pipe body 1, ensuring the neat appearance of the finished product.

[0033] It should be noted that the barrier layer 22 can adopt soft high-barrier materials such as aluminum foil, aluminized composite film, polyvinylidene chloride coated film, and ethylene-vinyl alcohol copolymer coextruded film.

[0034] See Figure 2 As shown, in this embodiment, further, the bottom of the inner liner body 210 extends away from the first connection part 211 to form a second connection part 212, and the end face of the second connection part 212 away from the inner liner body 210 is adhesively connected to the inner wall of the pipe body 1. By the end face of the second connection part 212 being adhesively connected to the inner wall of the pipe body 1, the connection stability between the inner liner 21 and the pipe body 1 is further enhanced, and the tight fit between the pipe shoulder 2 and the pipe body 1 is further ensured, thereby further enhancing the sealing performance of the connection part between the pipe shoulder 2 and the pipe body 1, and avoiding the leakage of the contents due to poor sealing of the connection part between the pipe shoulder 2 and the pipe body 1 during the use of the modular barrier structure for the hose shoulder.

[0035] See Figure 2As shown, in this embodiment, a fitting groove 236 adapted to fit the bending portion 11 is formed by inward depression on the outer wall of the shoulder 23. When the bending portion 11 is wrapped in the fitting groove 236, the outer wall of the bending portion 11 and the outer wall of the shoulder 23 are in the same plane. When the bending portion 11 is wrapped in the fitting groove 236, the tight fit between the bending portion 11 and the shoulder 23 is ensured through the fitting groove 236, thereby enhancing the sealing performance at the connection part between the bending portion 11 and the shoulder 23. Moreover, since the outer wall of the bending portion 11 and the outer wall of the shoulder 23 are in the same plane, the connection between the pipe shoulder 2 and the pipe body 1 is more firm, which is conducive to the bending portion 11 forming a stable fit 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 modular barrier structure for the hose shoulder more flat, improving the aesthetics of the product. And it is easy to assemble. Through the fitting groove 236, the bending portion 11 can be more easily fitted and wrapped with the shoulder 23, simplifying the assembly process and improving the production efficiency.

[0036] In other embodiments, the connection manner between the bending portion 11 and the shoulder 23 can also be selected according to actual situations. For example, a receiving groove (not shown) is formed by inward depression at one end of the shoulder 23 close to the bending portion 11, and the whole bending portion 11 is wrapped into the receiving groove. It can also play a connecting role while ensuring the flat and aesthetic appearance of the whole. As long as it can meet the actual requirements, the connection manner between the bending portion 11 and the shoulder 23 is not specifically limited herein.

[0037] See Figure 2As shown, in this embodiment, the barrier layer 22 is configured with a first pipe orifice portion 221 and a first fan-shaped portion 222 disposed at the lower end of the first pipe orifice portion 221 and integrally formed with the first pipe orifice portion 221; the inner lining body 210 is configured with a second pipe orifice portion 213 and a second fan-shaped portion 214 disposed at the lower end of the second pipe orifice portion 213 and integrally formed with the second pipe orifice portion 213, and a first connecting portion 211 is formed at the bottom of the second fan-shaped portion 214. The first fan-shaped portion 222 is integrally formed with the first pipe orifice portion 221, enhancing the overall structural stability of the barrier layer 22. The second fan-shaped portion 214 is integrally formed with the second pipe orifice portion 213, enhancing the overall structural stability of the inner lining body 210. And it makes the connection between the barrier layer 22 and the inner lining 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 close fit between the first fan-shaped portion 222 and the second fan-shaped portion 214, the connection between the barrier layer 22 and the inner lining body 210 is closer, thereby enhancing the sealing performance between the pipe shoulder 2 and the pipe body 1, reducing the leakage risk, ensuring the effective function of the barrier layer 22, and preventing problems such as oxygen penetration, moisture migration, microbial intrusion, and fragrance volatilization. During the assembly process of the pipe body 1 and the pipe shoulder 2, the inner lining body 210 can be accurately positioned and fitted with the inner wall of the pipe body 1 through the first connecting portion 211, ensuring the reliability and consistency of the connection between the pipe body 1 and the pipe shoulder 2.

[0038] Refer to Figure 2 As shown, in this embodiment, the injection shoulder 23 is configured with an orifice platform 231 that extends radially inwardly past the upper ends of the first pipe orifice portion 221 and the second pipe orifice portion 213 in sequence, and the orifice platform 231 forms a groove 232 for clamping the upper ends of the first pipe orifice portion 221 and the second pipe orifice portion 213. The groove 232 on the orifice platform 231 is used to clamp the upper ends of the first pipe orifice portion 221 and the second pipe orifice portion 213, ensuring the accurate positioning and stable connection of the first pipe orifice portion 221 and the second pipe orifice portion 213 on the injection shoulder 23, and enhancing the connection stability between the barrier layer 22 and the inner lining body 210 and the injection shoulder 23. And it makes the connection between the first pipe orifice portion 221 and the second pipe orifice portion 213 and the injection shoulder 23 closer, thereby enhancing the overall sealing performance.

[0039] Refer to Figure 2 And Figure 3As shown, in the present embodiment, the second pipe orifice portion 213 protrudes radially outward to form at least two sets of first protrusion portions 215 arranged in parallel. A first card slot 216 is formed between adjacent first protrusion portions 215. The first pipe orifice portion 221 is configured to have a second protrusion portion 223 corresponding to the first card slot 216 and snap into 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, so as to improve the connection stability between the barrier layer 22 and the inner lining body 210. And when performing the shoulder injection process, only by mechanically lifting the barrier layer 22 can the entire pipe body 1, inner lining 21 and barrier layer 22 to be shoulder-injected be grabbed and transferred, which is convenient for automated processing.

[0040] Refer to Figure 4 As shown, exemplarily, in some embodiments, the first pipe orifice portion 221 protrudes radially inward to form at least two sets of second protrusion portions 223 arranged in parallel. A second card slot 224 is formed between adjacent second protrusion portions 223. The second pipe orifice portion 213 is configured to have a first protrusion portion 215 corresponding to the second card slot 224 and snap into the second card slot 224. By rotating the barrier layer 22, two adjacent second protrusion portions 223 on the first pipe orifice portion 221 are clamped and fixed outside the first protrusion portion 215, and the first protrusion portion 215 is snapped into the second card slot 224, so as to improve the connection stability between the barrier layer 22 and the inner lining body 210.

[0041] Refer to Figure 2 As shown, the shoulder injection 23 is configured with a third pipe orifice portion 233 and a third fan-shaped 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 pipe orifice platform 231 extends radially inward from the third pipe orifice portion 233. An external thread 235 is formed on the outer periphery of the third pipe orifice portion 233. The third fan-shaped portion 234 and the third pipe orifice portion 233 are integrally formed, enhancing the overall structural stability of the shoulder injection 23. The pipe orifice platform 231 extends radially inward from the third pipe orifice portion 233 and is used to clamp the grooves 232 at the upper ends of the first pipe orifice portion 221 and the second pipe orifice portion 213, ensuring the stable connection between the barrier layer 22 and the inner lining body 210 and the shoulder injection 23. Through the external thread 235, the pipe shoulder 2 can be matched with the internal thread of a lid (not shown) or other accessories, facilitating the opening and closing of the modular barrier structure for the hose shoulder. 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 pipe shoulder 2 and a lid (not shown) or other accessories is not specifically limited.

[0042] Refer to Figure 2As shown, the bottom of the first sector portion 222 abuts against the first connecting portion 211 along the extending direction of the second sector portion 214; the bending portion 11 at least partially surrounds the bottom of the pouring shoulder 23 and covers the third sector portion 234. By the bottom of the first sector portion 222 abutting against the first connecting portion 211 along the extending direction of the second sector portion 214, the connection stability between the barrier layer 22 and the inner liner body 210 is enhanced, ensuring the accurate positioning and fixing of the barrier layer 22 on the inner liner body 210. The fitting groove 236 is formed by inward depression of the outer wall of the third sector portion 234, and the bending portion 11 is covered in the fitting groove 236 to ensure the close fit between the bending portion 11 and the pouring shoulder 23.
