A hose container

Abstract

The present application discloses a hose container, comprising a tube body, a flip-top structure, a support structure, and a piston. By providing a support structure at the top of the tube body and within the receiving space of the flip-top structure, the support structure's support during the extrusion of the tube body's contents effectively reduces the problem of the lid being unable to close due to deformation of the injection shoulder during use caused by the lack of a support member. Furthermore, by providing a piston in the tube body that fits tightly against the tube wall, the piston acts to expel the contents, effectively ensuring that the tube body's contents are fully drained, achieving zero residue, isolating the material from the air, and achieving vacuum at the lowest cost. Furthermore, the present application's integrated solution offers more compact components, saves materials, and is more environmentally friendly. Compared to conventional structures, it saves a significant amount of material, has better sealing performance, and eliminates the risk of leakage.

Description

Technical Field

[0001] The present application relates to the technical field of packaging hoses, in particular to a hose container. Background Art

[0002] Cosmetics refer to chemical industrial products or fine chemical products that are applied to any part of the human body, such as the skin, hair, nails, lips, and teeth, by applying, spraying, or other similar methods to cleanse, maintain, beautify, modify, or alter the appearance of the body, or to correct body odor and maintain a healthy appearance. Cosmetics require packaging in containers, and flexible tube containers are a common type of cosmetic container on the market. Existing flexible tube containers, such as the one-piece container disclosed in Publication No. CN115593784A, have the following disadvantages: the lid pops open when the tube is squeezed, and the lack of a support member within the shoulder causes the shoulder to deform and prevent the lid from closing at the end of use. A multifunctional flexible tube with a waterproof, mildew-proof, tear-free, and dual anti-theft structure disclosed in Publication No. CN221341966U also has the following disadvantages: the shoulder and lower cap are connected by a locking mechanism, such as a threaded connection. When the tube is squeezed at the end of use, the gap at the shoulder becomes larger and cannot be restored, trapping dirt and making cleaning difficult. Therefore, a flexible tube container has been proposed. Summary of the Invention

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0057] See also Figure 1 , shown is a structural schematic diagram of a hose container 1 provided in the first embodiment of the present application, wherein the hose container 1 includes a tube body 10, a flip cover structure 20 connected to the tube body 10, and a support structure 30 accommodated in the flip cover structure 20.

[0058] The tube body 10 comprises an opening 100 and a tail 102, which are arranged opposite each other. The cross-section of the opening 100 can be generally circular, elliptical, or otherwise. The walls 104 of the tube body 10 are connected at the tail 102 to form a flat, sealed end. The tube body 10 has a generally streamlined structure from the opening 100 to the tail 102. The tube body 10 includes a receiving cavity 103 enclosed by the walls 104. The empty cavity 103 can be filled with cosmetic contents. Under external pressure, the tube body 10 deforms, thereby extruding the contents from the tail 102 toward the opening 100.

[0059] Please also refer to Figure 2 , which is Figure 1 Schematic diagram of the exploded structure of the flexible tube container. The flip cover structure 20 includes a first butterfly cover assembly 21, a connecting assembly 24, and a second butterfly cover assembly 23. The first butterfly cover assembly 21 is connected to the second butterfly cover assembly 23 via the connecting assembly 24. In this way, the second butterfly cover assembly 23 can be rotatably connected to the first butterfly cover assembly 21 to move closer to or further away from the first butterfly cover assembly 21. In this embodiment, the first butterfly cover assembly 21, the second butterfly cover assembly 23, and the connecting assembly 24 form an integrated structure. In other embodiments, the second butterfly cover assembly 23 can be detachably connected to the first butterfly cover assembly 21 via the connecting assembly 24.

[0060] The first butterfly cover assembly 21 includes a discharge head 212 extending upward from the body 211 and a receiving space 214 extending downward from the body 211 for accommodating the support structure 30. Sidewalls 216 of the first butterfly cover assembly 21 are arranged along the circumference of the body 211 to form the receiving space 214. The sidewalls 216 of the first butterfly cover assembly 21 are provided with a step 210 at the end near the tube body 10. The step 210 mates with the opening 100 of the tube body 10. The second butterfly cover assembly 23 includes a cover body 230, a colored sheet 232, and a transparent top sheet 234. The transparent top sheet 234 is mounted on the cover body 230, with the colored sheet 232 disposed between the cover body 230 and the transparent top sheet 234. In this embodiment, the colored sheet 232 has one or more colors, and the transparent top sheet 234 can be transparent or translucent. When the transparent top sheet 234 and the colored sheet 232 overlap, a variety of appearance effects can be achieved. In other embodiments, the second butterfly cover assembly 23 may only include the cover body 230 .

[0061] The cover body 230 is provided with a sealing opening 236 that cooperates with the discharge head 212. When the second butterfly cover assembly 23 is covered on the first butterfly cover assembly 21, the discharge head 212 can be accommodated in the sealing opening 236, so that the hose container 1 is in a closed or closed state.

[0062] In one embodiment, the discharge head 212 of the first butterfly cover assembly 21 is fitted with an aluminum foil cover 40. This allows for anti-theft identification by determining whether the cover is present at the discharge head 212. For example, if the cover 40 is removed, it indicates that the flexible tube container 1 has been opened. Furthermore, the first and second butterfly cover assemblies 21 and 23 are fitted with a tear-free anti-theft structure 235. When the flexible tube container 1 is opened, the anti-theft strips on the anti-theft structure 235 automatically fall off, thus achieving dual anti-theft identification. The second butterfly cover assembly 23 is equipped with a lug to facilitate opening and closing of the flexible tube container 1.

[0063] The support structure 30 includes a bottle shoulder 31 and a reinforcement member 33. The bottle shoulder 31 has an outer side 37 adapted to the side wall 216 of the first butterfly cap assembly 21 and a discharge port 35 extending upward from the bottom of the support structure 30. The reinforcement member 33 is disposed on the outer side 37 of the bottle shoulder 31. In this embodiment, the first end of the discharge port 35 facing the first end of the tube body 10 is larger than the second end facing the discharge head 212, forming an inverted cone or funnel-shaped design, so as to facilitate the user to extrude the content with less force, achieving the purpose of convenient use. The bottle shoulder 31 further includes an inner side 36 extending upward from its bottom to match the first butterfly cap assembly 21. The inner side 36 is located within the outer side 37 and is substantially at the same height as the outer side 37. The inner side 36 has a generally "冂"-shaped structure.

[0064] Please refer to Figure 3 together, which is Figure 1 an enlarged schematic view of the structure at A in

[0065] In this embodiment, the support structure 30 is housed within the flip-top structure 20, which is connected to the tube body 10. Under external pressure, some or all of the contents of the tube body 10 can be extruded through the outlet 35 and the discharge head 212. When the flip-top structure 20 is connected to the tube body 10, the step 210 on the sidewall 216 of the first butterfly cover assembly 21 mates with the opening 100 of the tube body 10. At this point, the top of the opening 100 abuts against the step 210. In one embodiment, the step 210 and the opening 100 are integrally formed, or connected together by other bonding methods. In this embodiment, by disposing a support structure 30 at the top of the tube body 10 and within the receiving space 214 of the flip-top structure 20, the support structure 30 effectively reduces the problem of the lid not closing during use due to deformation of the tube shoulder caused by the lack of a support member. Furthermore, because the support structure 30 is tightly coupled to the sidewall 216 of the first flap assembly 21, the contents can be discharged directly from the outlet 35 and the discharge head 212, effectively avoiding the problem of a large gap between the shoulder and the lid body, which is difficult to clean, that occurs in a separate structure. In other embodiments, the first end of the support structure 30 can be directly connected to the opening 100 of the tube body 10, while the second end is received in the receiving space 214 of the first flap assembly 21 and connected to the body 211 and sidewall 216 of the first flap assembly 21 (e.g., as an integrated structure). At this time, the first butterfly cover assembly 21 is not directly connected to the opening portion 100 of the tube body 10. Since the outer edge 37 of the support structure 30 is arranged along the circumference direction of the bottle shoulder 31, and the top of the inner edge 36 can be stopped at the main body 211 of the first butterfly cover assembly 21, the force applied to the support structure 30 can be dispersed along the circumferential direction of the side wall 216 of the first butterfly cover assembly 21, which greatly reduces the deformation of the support structure 30 or the enlargement of the gap between the shoulder and the cover body.

[0066] In this embodiment, the flexible tube container can be made of commonly used materials such as PP and PE. All components can be made of the same material for easier recycling. Bio-based materials, PLA, PCR, biodegradable and environmentally friendly materials, or synthetic materials derived from various plant extracts can also be used, achieving energy conservation and environmental protection. The tube body can also be manufactured using multi-layer composite materials, and high-barrier materials such as EVOH can be added to ensure the freshness of the material and extend its service life.

[0067] In the separate structural design of the first butterfly cover assembly 21 and the second butterfly cover assembly 23, the first butterfly cover assembly 21 is provided with a mounting groove on the peripheral side of the main body, and the end of the connecting assembly 24 connected to the first butterfly cover assembly 21 is provided with a plug-in component. In this way, after the plug-in component is inserted into the mounting groove, the second butterfly cover assembly 23 can move closer to or away from the first butterfly cover assembly 21, thereby realizing the opening and closing operation of the hose container 1.

[0068] See also Figure 4 , which is a schematic diagram of the structure of a flexible tube container in the second embodiment of this application. Compared to the previous embodiment, the main difference is that the flip cover structure 20 of the flexible tube container 1 in this embodiment is a separate structure, comprising a first flap assembly 21 and a second flap assembly 23. The second flap assembly 23 can be selectively connected to the first flap assembly 21 via a connecting assembly 24. The second flap assembly 23 and connecting assembly 24 can be an integrated structure. For the same parts as the previous embodiment, please refer to the relevant content and will not be repeated here.

[0069] Please also refer to Figure 5 , which is Figure 4 Schematic diagram of the cross-sectional structure of the flexible tube container. In this embodiment, the first butterfly cover assembly 21 has a mounting slot 219 defined on the sidewall 216 of the body 211. A connector 240 is provided at one end of the connecting assembly 24 that connects to the first butterfly cover assembly 21. Once the connector 240 is inserted into the mounting slot 219, the second butterfly cover assembly 23 can move closer to or further from the first butterfly cover assembly 21, thereby enabling the flexible tube container 1 to be opened and closed.

[0070] Please also refer to Figure 6 , which is Figure 4 Schematic diagram of the exploded structure of the middle flip cover structure and the support structure. In this embodiment, a mounting groove 219 is provided at the junction of the top and the side of the first butterfly cover assembly 21. A base 32 is provided on the support structure 30 at a position relative to the mounting groove 219. A notch is provided on the outer side 37 of the bottle shoulder 31, and the inner side 36, the notch, and the bottom of the bottle shoulder 31 together form the base 32. In this embodiment, the height of the first side 213 formed by the bottom of the mounting groove 219 and the side wall 216 is lower than the height of the second side extending from the bottom to the upper surface of the body 211. In this way, when the connector 240 is installed in the mounting groove 219 in a first direction (e.g., vertical direction), the lower surface of the connecting portion 246 abuts against the top of the first side 213, thereby improving the accuracy and convenience of installation. In this embodiment, the support structure 30 is further provided with a rib 34 connected to the inner side 36, which is used to abut against the second side of the mounting groove 219 when the mounting groove 219 is installed to the base 32, so that the mounting groove 219 is more tightly installed on the base 32.

[0071] The mounting groove 219 has a roughly U-shaped cross-section and a groove 217 formed on its inner surface. The connecting assembly 24 includes a connector 240 that connects to a connecting portion 246 of the second butterfly cover assembly 23. The connector 240 has a roughly T-shaped cross-section and is provided with a number of protrusions 245 on its two side edges 242. When the connector 240 is mounted in the mounting groove 219, the protrusions 245 can be installed or snapped into corresponding grooves 217. In this embodiment, by providing the mounting grooves 219 on the top and outer connecting portions of the first butterfly cover assembly 21, the second butterfly cover assembly 23 is mounted to the first butterfly cover assembly 21 via the connector 240, facilitating processing and assembly. In this embodiment, since the body 211 is partially occupied by the mounting groove 219, when the connector 240 is installed in the mounting groove 219, the upper surface of the connector 240 is flush with the plane of the body 211, making the hose container easy to clean and preventing the contents from remaining on the body. Furthermore, since the support structure 30 is located within the receiving space 214 of the first butterfly cover assembly 21, the outer edge 37 of the support structure 30 is arranged along the circumference of the bottle shoulder 31 and contacts and connects with the inner surface of the sidewall 216 of the first butterfly cover assembly 21, and the top of the inner edge 36 can abut against the body 211 of the first butterfly cover assembly 21 to perform its supporting function. This not only facilitates processing and assembly, but also effectively reduces the problem of the lid not closing due to deformation of the tube shoulder during use caused by the lack of a support member. Furthermore, the mounting groove 219 is separated from the receiving space 214, preventing external water stains from flowing into the support structure 30 through the mounting groove 219, effectively reducing the occurrence of water stains. When the hose container 1 is placed upside down, water stains (if any) in the mounting groove 219 can be drained away under the action of gravity.

[0072] See also Figure 7 , which is a schematic diagram of the structure of the hose container in the third embodiment of the present application. Compared with the first embodiment, the main difference is that the flip cover structure 20 of the hose container 1 in this embodiment is a separate structure, which includes a first butterfly cover component 21 and a second butterfly cover component 23, wherein the second butterfly cover component 23 can be selectively connected to the first butterfly cover component 21 via a connecting component 24, and the second butterfly cover component 23 and the connecting component 24 can be an integrated structure. Compared with the second embodiment, the main difference is that the connector 240 and the mounting slot 220 (shown in FIG. 2 ) are connected to each other. Figure 9 ) is different. For the same parts as in the above embodiments, please refer to the relevant parts and no further details will be given here.

[0073] Please also refer to Figure 8 , which is Figure 7 In this embodiment, a mounting groove 220 (shown in FIG. 2 ) is provided on the side of the first butterfly cover assembly 21. Figure 9), a connector 240 is provided at one end of the connecting component 24 connected to the first butterfly cover component 21. In this way, after the connector 240 is inserted into the mounting groove 220 in the direction of the discharge head 212 (such as the horizontal direction), the second butterfly cover component 23 can move closer to or away from the first butterfly cover component 21 to realize the opening and closing operation of the hose container.

[0074] Please also refer to Figure 9 , which is Figure 7 Schematic diagram of the exploded structure of the middle flip cover structure and support structure. In this embodiment, a mounting groove 220 is defined on the sidewall 216 of the first butterfly cover assembly 21. The mounting groove 220 has a roughly U-shaped cross-section and is provided with a plurality of grooves on its inner surface. A base 32 is defined on the support structure 30 relative to the mounting groove 220. A notch 372 is defined on the outer edge 37 of the bottle shoulder 31. The base 32 is comprised of the notch 372, the inner edge 36, and the bottom of the bottle shoulder 31. When the support structure 30 is housed within the flip cover structure 20, the mounting groove 220 abuts against the inner edge 36 of the base 32, allowing the mounting groove 220 to be more tightly mounted on the base 32.

[0075] The connecting assembly 24 includes a connector 240 and a connecting portion 246 for the second butterfly cover assembly 23. The connector 240 is provided with a plurality of ribs 243 on both sides, which can be mounted in grooves corresponding to the mounting grooves 220. In this embodiment, by providing the mounting grooves 220 on the outer side of the first butterfly cover assembly 21, the second butterfly cover assembly 23 is mounted to the first butterfly cover assembly 21 via the connector 240, thereby facilitating processing and assembly. Simultaneously, the support structure 30 is mounted within the receiving space 214 of the first butterfly cover assembly 21. The outer edge 37 of the support structure 30 is arranged along the circumference of the bottle shoulder 31 and contacts and connects with the inner surface of the sidewall 216 of the first butterfly cover assembly 21. The top of the inner edge 36 can abut against the body 211 of the first butterfly cover assembly 21, thereby fulfilling its supporting function. This not only facilitates processing and assembly, but also effectively reduces the problem of the container not being able to close due to deformation of the tube shoulder during use due to the lack of a support member. The mounting groove 220 is separated from the receiving space 214, preventing external water stains from flowing into the support structure 30 through the mounting groove 220, effectively reducing the occurrence of water stains. When the hose container 1 is placed upside down, water stains (if any) in the mounting groove 220 can be drained away under the action of gravity. In other embodiments, ribs 34 may also be provided within the shoulder 31 to provide abutment against the connector 240 when the connector 240 is mounted in the mounting groove 219 in a second orientation (e.g., horizontal).

Compared to the first embodiment, the main difference lies in: the flip cover structure 20 of the flexible tube container 1 in this embodiment is a separate structure, comprising a first butterfly cover assembly 21 and a second butterfly cover assembly 23. The second butterfly cover assembly 23 can be selectively connected to the first butterfly cover assembly 21 via a connecting assembly 24. The second butterfly cover assembly 23 and the connecting assembly 24 can be an integrated structure. Compared to the second and third embodiments, the main difference lies in the different structures of the connector 240 and the mounting slot 221. For the same parts as the previous embodiments, please refer to the relevant content and will not be repeated here.

[0077] Please also refer to Figure 11 , which is Figure 10 In this embodiment, a mounting groove 221 (shown in FIG) is provided at the junction of the top and the side of the first butterfly cover assembly 21. Figure 12 ), a connector 240 is provided at one end of the connecting component 24 connected to the first butterfly cover component 21. In this way, after the connector 240 is inserted into the mounting groove 221, the second butterfly cover component 23 can move closer to or away from the first butterfly cover component 21 to realize the opening and closing operation of the hose container.

[0078] Please also refer to Figure 12 , which is Figure 10 Schematic diagram of the exploded structure of the middle flip cover structure and support structure. In this embodiment, a mounting groove 221 is defined at the junction of the top and sidewalls 216 of the main body 211 of the first butterfly cover assembly 21. The mounting groove 221 has a roughly U-shaped cross-section and is provided with a plurality of grooves 217 on both sides. The support structure 30 defines a base 32 at a position corresponding to the mounting groove 221. A notch is defined on the outer edge 37 of the shoulder 31. The base 32 is composed of the notch, the inner edge 36, and the bottom of the shoulder 31. The support structure 30 is also provided with ribs 34. When the support structure 30 is accommodated in the flip cover structure 20, the mounting groove 221 abuts against the inner edge 36 and ribs 34 of the base 32, allowing the mounting groove 221 to be more tightly mounted on the base 32.

[0079] The connecting assembly 24 includes a connector 240 and a connecting portion 246 that connects the connector 240 to the second butterfly cover assembly 23. A plurality of protrusions 245 are provided on both sides of the connector 240. The protrusions 245 can be installed in the grooves 217 corresponding to the mounting grooves 221. In this embodiment, by providing the mounting grooves 221 at the top and outer connection of the first butterfly cover assembly 21, the second butterfly cover assembly 23 is installed on the first butterfly cover assembly 21 via the connector 240, which facilitates processing and assembly. In this embodiment, when the connector 240 is installed in the mounting groove 221 in a first orientation (e.g., vertically), the upper surface of the connector 240 is flush with the plane of the body 211. Furthermore, because the support structure 30 is located within the receiving space 214 of the first butterfly cover assembly 21, the outer edge 37 of the support structure 30 is arranged along the circumference of the bottle shoulder 31 and contacts and connects with the inner surface of the sidewall 216 of the first butterfly cover assembly 21. The top of the inner edge 36 can abut against the body 211 of the first butterfly cover assembly 21, thereby fulfilling its supporting function. This not only facilitates processing and assembly, but also effectively reduces the problem of the lid not closing due to deformation of the tube shoulder during use caused by the lack of a support member. The mounting groove 221 is separated from the receiving space 214, effectively preventing external water stains from flowing through the mounting groove 221 into the support structure 30, thereby reducing the occurrence of water stains. When the hose container 1 is placed upside down, water stains (if any) in the mounting groove 221 can be drained away under the action of gravity.

[0080] In the existing related technologies, when squeezing the contents out of the tube body, there is a possibility that the contents cannot be completely squeezed out, resulting in some contents remaining in the tube body, causing waste. In response to this, the present application also provides a technical solution that can fully squeeze out the contents and reduce the amount of contents remaining in the tube body.

[0081] See also Figure 13 , which is a schematic diagram of the first state of the piston in the fifth embodiment of the present application. In order to fully squeeze out the contents in the tube body, the present application provides a technical solution of arranging a movable piston in the tube body. Here, this embodiment uses the movable piston applied to the above-mentioned second embodiment as an example for explanation. Specific personnel in this field should know that the technical solution of arranging a movable piston in the tube body is applicable to any of the aforementioned technical solutions and their variations. In this embodiment, a movable piston 60 is provided in the tube body 10. In the initial state, the piston 60 can be set at the tail 102 position of the tube body 10, and then the support structure 30 and the flip structure 20 are assembled, so that the tube body 10 and the flip structure 20 can be an integrally formed structure, or the tube body 10, the support structure 30 and the flip structure 20 can be an integrally formed structure. Thereafter, the contents are filled into the tube body 10, and the sealing cover 40 is affixed.

[0082] Please also refer to Figure 14 , which is Figure 13Schematic diagram of the structure of the piston. The piston 60 includes a detachable extrusion portion 604 and a pressing portion 605. The extrusion portion 604 includes a central column 601 extending upward from the top 603 and a protrusion 609 provided on the outside of the top 603. The extrusion portion 604 includes a contact portion 610 provided along the circumference of its side. The contact portion 610 is provided on the side of the extrusion portion 604 (i.e., higher than the side of the extrusion portion 604), and a first latch 611 is formed at both ends of the contact portion 610 that are not connected to the extrusion portion 604 (shown in FIG. Figure 15 ) and the second fastener 612 (shown in Figure 15 The pressing portion 605 has a generally arc-shaped surface, which facilitates the user's squeezing operation and includes an elastic member 615 (shown in FIG. 1 ) disposed at the top. Figure 15 ) and a guide member 607 disposed at the bottom. The guide member 607 is adapted to the shape of the tail portion 102 of the tube body 10. When installing the extrusion portion 604 and the pressing portion 605, the elastic member 615 of the pressing portion 605 can be attached to the second latching member 612 of the extrusion portion 604, and the two can be elastically coupled. In other embodiments, different types of pressing portions 605 may be provided to achieve adaptation to the shape of the tube body 10.

[0083] Please also refer to Figure 15 , shown as Figure 14 Schematic diagram of the cross-sectional structure of the middle piston. In this embodiment, the cross-section of the contact portion 610 has an arc structure with high ends and a low middle in the axial direction of the piston 60. When the piston 60 is set in the tube body 10, the first latch 611 and the second latch 612 of the contact portion 610 can be attached to the tube wall 104 of the tube body 10, and the middle position of the contact portion 610 is at a certain distance from the tube wall 104 of the tube body 10. In this way, while ensuring that the contact portion 610 is tightly attached to the tube body 10, the contact area between the contact portion 610 and the tube wall 104 is reduced, so that the piston 60 can be pushed from the tail 102 of the tube body 10 toward the opening 100 with a smaller force.

[0084] Also see Figure 16 , shown in this application Figure 13 Schematic diagram of the second state of the piston. In order to better squeeze out the contents and reduce the residual contents in the tube body, in this embodiment, when the piston 60 moves to the top of the tube body 10, it is necessary to ensure that the extrusion portion 604 of the piston 60 matches the accommodating space formed by the flip cover structure 20 and the support structure 30. Please refer to Figure 17 , which is a schematic diagram of the flip cover structure and the support structure in another embodiment of the present application. Figure 5 In contrast, in this embodiment, the step portion 210 of the side wall 216 of the first butterfly cover assembly 21 disposed at the end portion close to the tube body 10 has a first step 271 and a second step 272. Figure 18 , shown as Figure 16 An enlarged schematic diagram of the structure at point B in the middle. When the piston 60 moves to the top of the tube body 10, the piston 60 circumferentially abuts the tube wall 104 of the tube body 10, the center column 601 passes through the discharge head 212, the top 603 of the extrusion portion 604 contacts the inner surface of the bottle shoulder 31, the protrusion 609 abuts the end of the outer edge 37 of the bottle shoulder 31, and the first latch 611 abuts the second step 272 of the step 210 of the first butterfly cover assembly 21, where the first step 271 of the step 210 of the first butterfly cover assembly 21 is connected to the end of the opening 100 of the tube body 10. In this way, by configuring the piston 60 to match the accommodation space formed by the flip-top structure 20 and the support structure 30, the contents of the tube body 10 can be effectively discharged.

[0085] See also Figure 19 , which is a structural diagram of another piston of the present invention. By setting the extrusion part 604 and the pressing part 605 of the detachable structure, the tail part 102 of the tube body 10 can be replaced in a simple and convenient manner. Figure 15 The difference between the two is that the guide member 607 of the piston 60 is different. For the same parts as the above embodiment, please refer to the relevant parts, which will not be repeated here. Figure 20 , shown as Figure 19 In this embodiment, the guide member 607 is provided at the bottom of the pressing portion 605 and has a transition portion from large to small, and the cross section is roughly heart-shaped. Compared with the previous embodiment, this embodiment can provide a better grip position.

[0086] See also Figure 21 , which is a structural diagram of another piston of the present invention. By setting the extrusion part 604 and the pressing part 605 of the detachable structure, the tail part 102 of the tube body 10 can be replaced in a simple and convenient manner. Figure 15 、 Figure 19 The difference is that the extrusion portion 604 and the pressing portion 605 of the piston 60 are different. For the same parts as those in the above embodiment, please refer to the relevant parts and no further details will be given here. Figure 22 , shown as Figure 21 Schematic cross-section of the piston. In this embodiment, the extrusion portion 604 includes an installation space. When the pressing portion 605 is accommodated in the installation space, the bottom of the pressing portion 605 extends out of the installation space, providing a support point for the user to press. In this embodiment, the pressing portion 605 is a ball-shaped pressing portion with a circular cross-section. In other embodiments, it can also have other shapes, such as an elliptical shape. By providing a ball-shaped pressing portion, the user experience on the elliptical hose will be better due to the lighter and smoother squeezing feel in the push-piston extrusion structure.

[0087] In this embodiment, a reinforcement member 619 can be provided at the second latch 612 of the contact portion 610. The reinforcement member 619 protrudes from the surface of the second latch 612. Different reinforcement members 619 are spaced at a preset distance to improve the degree of contact with the tube wall of the tube body 10. In this way, while ensuring that the first latch 611 of the contact portion 610 is in close contact with the tube body 10, the reinforcement member 619 provided at the second latch 612 further reduces the contact area between the second latch 612 and the tube wall 104, thereby achieving the goal of pushing the piston 60 from the tail 102 of the tube body 10 toward the opening 100 with a smaller force. It is understandable that the technical solution of providing a reinforcement member 619 at the second latch 612 of the contact portion 610 can also be applied to any of the aforementioned related embodiments.

[0088] See also Figure 23 , shows a schematic structural diagram of another embodiment of a flexible tube container according to the present application. In this embodiment, the flexible tube container 1 also provides a remaining content indicator. In this embodiment, a transparent window 650 is defined in the sidewall 216 of the first butterfly cap assembly 21. The transparent window 650 can be located in the area between the step 210 and the end of the outer edge 37 of the bottle shoulder 31. Thus, when the piston 60 reaches the top of the tube body 10, the center post 601 can pass through the discharge head 212, indicating that the contents of the tube body 10 have been completely discharged. Furthermore, when the piston 60 reaches the top of the tube body 10, the top 603 of the extrusion portion 604 contacts the inner surface of the bottle shoulder 31, the protrusion 609 abuts the end of the outer edge 37 of the bottle shoulder 31, and the first latch 611 abuts the second step 272 of the step 210 of the first butterfly cap assembly 21. The user can see the piston 60 through the transparent window 650, indicating that the contents have been completely discharged. In one embodiment, the surface of the piston 60 can be colored red, blue, or other colors that differ from the contents, making it easier for the user to confirm whether the contents have been completely discharged. This allows the user to determine whether the center column 601 has passed through the discharge head 212 and / or whether the piston 60 can be viewed through the transparent window 650, indicating that the contents have been completely discharged. In this embodiment, a transparent strip 110 extending along the length of the tube 10 is welded to the tube wall to provide a remaining amount indicator.

[0089] In addition, an adjustment portion 630 may be provided at the position of the discharge head 212 of the first butterfly cover assembly 21. When in use, the user can adjust the discharge aperture size according to the consistency of the material to achieve the optimal extrusion discharge feel.

[0090] Please refer to Figure 13An indicator area 261 made of a transparent two-color extruded tube process is provided on the tube wall of the tube body 10. The indicator area 261 extends along the length of the tube body. By observing the position of the contents and / or the position of the piston 60 through the indicator area 261, the remaining amount of the contents in the tube body 10 can be conveniently and quickly determined.

[0091] The above-mentioned embodiment adopts an integrated solution of tube body, support structure and covering structure. The components are more compact, material-saving and more environmentally friendly. Compared with conventional structures, a large amount of material is saved, the sealing performance is better, and there is no risk of leakage. Conventional two-piece structures have the risk of leakage if the screw threads are loose. The appearance is simpler and more beautiful. Through a variety of ball-type pushing and extruding structures, zero residue is achieved. Through a variety of ball-type pushing and extruding structures, the piston structure is pushed to isolate the material body from the air, and vacuum is achieved at the lowest cost.

[0092] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and inventive concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
