[0018] The hardness of the valve sleeve is greater than the hardness of the valve core.

[0019] Another object of the present invention is to provide a hose packaging which, by adopting the one-way valve assembly mentioned above, can not only realize quantitative material removal, but also achieve one-way sealing to ensure the cleanliness of the material in the hose container. In addition, the structure is simple and reliable.

[0020] To achieve this object, the present invention adopts the following technical solutions:

[0021] The hose packaging comprises a hose container and the one-way valve assembly as described above, wherein the one-way valve assembly is installed at the discharge port in the hose container.

[0022] As an optional solution, a guide portion is provided in the hose container, the guide portion is provided around the discharge port, and the guide portion is configured to guide the movable portion to move between the first position and the second position.

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0053] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0054] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0055] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0056] This embodiment provides a one-way valve assembly and a hose package, wherein the hose package includes the one-way valve assembly.

[0057] like Figure 1-Figure 3 As shown, the hose packaging includes a hose container 20 and a cap 30. The hose container 20 includes a container body 21 and a discharge tube 23. The container body 21 is used to hold materials, and the discharge tube 23 is provided with a discharge port 231. In this embodiment, the hose container 20 is made of a material with a certain degree of elastic deformation. Therefore, when the user squeezes the container body 21, the material inside the container body 21 can be discharged through the discharge port 231. In this embodiment, the hose container 20 is made of PE material, which has a low hardness, making the squeezing operation more convenient for the user. The cap 30 is used to cover one end of the discharge tube 23 of the hose container 20. The cap 30 can cover the discharge port 231, thereby preventing external impurities from entering the hose container 20 through the discharge port 231 and contaminating the materials inside the hose container 20.

[0058] like Figure 2As shown, in this embodiment, the container body 21 is generally cylindrical, and the discharge pipe 23 is a tapered cylindrical structure. The diameter of the container body 21 is larger than the maximum diameter of the discharge pipe 23. In some embodiments, the hose container 20 further includes a transition pipe 22 disposed between the container body 21 and the discharge pipe 23. The transition pipe 22 has a smaller diameter than the container body 21 but larger than the maximum diameter of the discharge pipe 23. The transition pipe 22 creates a transition in the cross-section of the hose container 20, facilitating extrusion when the remaining material in the hose container 20 is low. Furthermore, a surface is formed on the exterior of the hose container 20 between the container body 21 and the transition pipe 22. When the cap 30 is installed on the hose container 20, it abuts against this surface. This surface not only serves as a position limiter for the cap 30 but also ensures a smooth and regular appearance for the entire hose package. In this embodiment, the container body 21, transition pipe 22, and discharge pipe 23 are integrally formed, which not only facilitates processing but also provides excellent sealing.

[0059] like Figure 2-Figure 4 As shown, a sealing plug 32 is provided on the inner wall of the cap 30. When the cap 30 is covered on the hose container 20, the sealing plug 32 is inserted into the discharge port 231. The sealing plug 32 can form a seal on the discharge port 231 to prevent the material in the hose container 20 from oxidizing and deteriorating. In addition, during the storage or transportation of products packaged in the hose, if the hose container 20 is accidentally squeezed, the sealing plug 32 can prevent the material in the hose container 20 from being squeezed out.

[0060] like Figure 2-Figure 4 As shown, the cap 30 is provided with a guide sleeve 33. When the cap 30 is placed on the hose container 20, the portion of the hose container 20 provided with the discharge port 231 (i.e., the end of the discharge tube 23) is inserted into the guide sleeve 33. The guide sleeve 33 serves as a guide for the installation of the cap 30, thereby ensuring that the sealing plug 32 can be smoothly inserted and seal the discharge port 231, thereby improving the convenience of the cap 30 installation. In this embodiment, the guide sleeve 33 is arranged around the outer circumference of the sealing plug 32.

[0061] like Figure 2-Figure 4As shown, the inner wall of the cap 30 is provided with a first threaded portion 31, and the outer circumference of the hose container 20 is provided with a second threaded portion 221, with the first threaded portion 31 and the second threaded portion 221 being threadedly connected. This threaded connection between the cap 30 and the hose container 20 not only ensures a reliable connection but also provides a certain sealing effect, thereby preventing the material in the hose container 20 from being contaminated by external substances or oxidized by air. In this embodiment, the second threaded portion 221 is provided on the outer circumference of the transition tube 22. Therefore, after the first threaded portion 31 and the second threaded portion 221 are threadedly connected, the end surface of the cap 30 abuts against the end surface between the container body 21 and the transition tube 22. Of course, in other embodiments, the cap 30 and the hose container 20 can also be connected by a snap-fit ​​connection, which is not limited here. In this embodiment, the cap 30 is made of PP material, which has sufficient hardness and is not easily deformed. Therefore, its combination with the hose container 20 ensures a reliable connection and a good sealing effect on the discharge port 231.

[0062] When using the hose container 20 to squeeze out the material, it is difficult to control the force, which may lead to problems such as excessive extrusion at one time, affecting the user experience. In addition, in actual use, it is easy for the cap 30 to be lost or the user to forget to replace the cap 30 after use, resulting in the discharge port 231 being open for a long time, and the material in the hose container 20 being contaminated or oxidized.

[0063] In this regard, Figure 5 and Figure 6 As shown, the one-way valve assembly 10 in this embodiment is installed at the discharge port 231 of the hose container 20. The one-way valve assembly 10 includes a valve sleeve 11 and a valve core 12. The valve sleeve 11 is disposed within the hose container 20 and encloses an installation space 40 with the inner wall of the hose container 20. The valve sleeve 11 is provided with an inlet 111, which communicates with the installation space 40 and the inner cavity of the hose container 20, and the discharge port 231 communicates with the installation space 40. The valve core 12 is disposed within the installation space 40 and includes a movable portion 121. The movable portion 121 is movable between a first position and a second position. The movable portion 121 blocks the inlet 111 in the first position and blocks the discharge port 231 in the second position. Between the first and second positions, the inlet 111 and the discharge port 231 are connected.

[0064] When it is necessary to take material from the hose container 20, the hose container 20 is squeezed, and the material in the hose container 20 is pressurized to enter the feed port 111 and push the movable part 121, so that the movable part 121 moves from the first position to the second position. At this time, the feed port 111 and the discharge port 231 are connected, and the material can enter the installation space 40 from the feed port 111 and further be discharged from the discharge port 231. When the movable part 121 moves to the second position, it blocks the discharge port 231. At this time, the hose container 20 is squeezed again, and the material in the hose container 20 is discharged. No more material will be discharged. Since the movable part 121 has a fixed stroke from the first position to the second position, the amount of material discharged each time the hose container 20 is pressed is constant, thereby realizing the function of quantitative material discharge and improving the convenience and accuracy of the user in taking out the material. When the hose container 20 is no longer squeezed, the external atmospheric pressure pushes the movable part 121 to return from the second position to the first position. At this time, the movable part 121 blocks the feed port 111, thereby achieving sealing of the material in the hose container 20 and preventing external contaminants from continuously entering the hose container 20 and contaminating the material.

[0065] Optionally, in this embodiment, the hardness of the valve sleeve 11 is greater than that of the valve core 12. Choosing a harder material for the valve sleeve 11 prevents deformation and ensures that the amount of material discharged remains constant during the movement of the movable portion 121 from the first position to the second position. The valve core 12 is constructed of a less hard material to facilitate smooth movement of the movable portion 121 from the first position to the second position when the user squeezes the flexible tube container 20, and to facilitate smooth return of the movable portion 121 from the second position to the first position under atmospheric pressure after squeezing the flexible tube container 20. Optionally, in this embodiment, the valve sleeve 11 is constructed of PP, and the valve core 12 is constructed of PE.

[0066] In this embodiment, Figure 5-Figure 7 As shown, the valve sleeve 11 is generally cylindrical in structure. The end of the valve sleeve 11 near the discharge pipe 23 is open to facilitate smooth installation of the valve core 12 within the valve sleeve 11. The end of the valve sleeve 11 away from the discharge port 231 has an end plate 114, and the feed port 111 is provided on this end plate 114. The valve sleeve 11 is installed in the transition pipe 22 and abuts against the table between the transition pipe 22 and the discharge pipe 23, thereby enclosing and forming an installation space 40.

[0067] like Figure 5 and Figure 6As shown, the valve sleeve 11 is provided with a protrusion 113 on its outer circumference, and a mating groove 222 is provided on the inner wall of the flexible tube container 20. The protrusion 113 engages with the mating groove 222, thereby connecting the valve sleeve 11 to the flexible tube container 20. In this embodiment, the mating groove 222 is provided on the inner wall of the transition tube 22. The protrusion 113 is provided around the circumference of the valve sleeve 11, and the mating groove 222 is correspondingly provided around the inner wall of the transition tube 22, thereby ensuring a secure connection between the valve sleeve 11 and the flexible tube container 20. In other embodiments (not shown), the valve sleeve 11 may be provided with a groove and the flexible tube container 20 may be provided with a protrusion, with the valve sleeve 11 secured by the engagement of the protrusion and the groove, although this is not limited here.

[0068] like Figure 5-Figure 8 As shown, the valve core 12 also includes a mounting portion 122 and a connecting portion 123. The mounting portion 122 is connected to the valve sleeve 11, and the connecting portion 123 connects the movable portion 121 and the mounting portion 122. When the hose container 20 is squeezed, the connecting portion 123 elastically deforms, allowing the movable portion 121 to move from a first position to a second position. In this embodiment, the reciprocating motion of the movable portion 121 is achieved through local elastic deformation of the valve core 12 itself, resulting in a simple structure and low cost. In this embodiment, the mounting portion 122, connecting portion 123, and movable portion 121 are integrally formed, which not only facilitates molding but also prevents damage at the connection points of the connecting portion 123 with the mounting portion 122 and movable portion 121, respectively.

[0069] In this embodiment, the mounting portion 122 is cylindrical in shape, the movable portion 121 is disposed within the mounting portion 122 and spaced apart from the mounting portion 122, and the connecting portion 123 is arranged radially relative to the valve core 12. Therefore, when the movable portion 121 leaves the first position but before reaching the second position, material within the hose container 20 can flow from the feed port 111 into the space between the mounting portion 122 and the movable portion 121, and then further into the discharge port 231.

[0070] like Figure 5 and Figure 7 As shown, one of the outer circumferential surface of the mounting portion 122 and the inner circumferential surface of the valve sleeve 11 is provided with a slot 112, and the other is provided with a protrusion 1221. The slot 112 and the protrusion 1221 are engaged with each other. The engagement of the slot 112 and the protrusion 1221 enables the valve core 12 to be fixedly mounted on the valve sleeve 11, resulting in a simple structure and convenient assembly. In this embodiment, the protrusion 1221 is provided on the outer circumferential surface of the mounting portion 122, and the slot 112 is provided on the inner circumferential surface of the valve sleeve 11. Optionally, the protrusion 1221 is provided along the outer circumference of the mounting portion 122, and the slot 112 is provided along the inner circumference of the valve sleeve 11, thereby ensuring the reliability of the connection between the valve core 12 and the valve sleeve 11.

[0071] like Figure 8As shown, at least two connecting portions 123 are provided, spaced and evenly spaced along the circumference of the mounting portion 122. This arrangement ensures that the movable portion 121 is subjected to uniform force along the circumference. Therefore, when the user squeezes the hose container 20, the movable portion 121 does not deviate from its direction of movement, allowing it to accurately reach the second position and block the discharge port 231.

[0072] In this embodiment, Figure 8 As shown, the valve core 12 includes three connecting portions 123. In other embodiments, the specific number of connecting portions 123 can be flexibly set according to needs and is not limited here. Optionally, the connecting portion 123 includes an extension section 1232 and two connecting ends 1231, wherein the two connecting ends 1231 are respectively arranged at both ends of the extension section 1232, and one connecting end 1231 is connected to the mounting portion 122, and the other connecting end 1231 is connected to the movable portion 121. The extension section 1232 extends along the circumference of the valve core 12. Under the condition that the overall radial dimension of the valve core 12 is constant, the length of the extension section 1232 can be increased, thereby ensuring that the entire connecting portion 123 has sufficient deformation to meet the use requirements.

[0073] like Figure 7 and Figure 8 As shown, the movable portion 121 is generally a shaft-shaped component, one end of which is used to block the feed port 111, and the other end is used to block the discharge port 231. Optionally, the movable portion 121 can be a stepped shaft structure to ensure that the diameter of one end matches the feed port 111 and reliably blocks the feed port 111, and the diameter of the other end matches the discharge port 231 and reliably blocks the discharge port 231.

[0074] like Figure 5 and Figure 8 As shown, the movable portion 121 includes a first blocking surface 1211, which is arranged at the end of the movable portion 121 facing the feed port 111. The first blocking surface 1211 is an arc-shaped surface and protrudes from the lower surface of the mounting portion 122 (the surface of the mounting portion 122 facing the end plate 114 of the valve sleeve 11). When the movable portion 121 is in the first position, the movable portion 121 elastically presses against the end surface of the feed port 111, and the first blocking surface 1211 partially extends into the feed port 111. By providing the elastic pressure between the first blocking surface 1211, the movable portion 121, and the end surface of the feed port 111, the reliability of the movable portion 121 sealing the feed port 111 can be improved. Optionally, in this embodiment, the first blocking surface 1211 can be a spherical surface.

[0075] like Figure 5 and Figure 7As shown, the movable portion 121 further includes a second blocking surface 1212, which is disposed at one end of the movable portion 121 facing the discharge port 231. The second blocking surface 1212 is an arcuate surface. When the movable portion 121 is in the second position, the second blocking surface 1212 at least partially extends into the discharge port 231. By configuring the second blocking surface 1212 as an arcuate surface, when the user squeezes the hose container 20, the second blocking surface 1212 partially extends into the discharge port 231, thereby preventing the movable portion 121 from tilting during movement, ensuring the reliability of the movable portion 121 in blocking the discharge port 231, and thereby ensuring the accuracy of quantitative material removal.

[0076] like Figure 5 and Figure 9 As shown, a guide portion 24 is provided within the hose container 20. The guide portion 24 is disposed around the discharge port 231 and is configured to guide the movable portion 121 between a first position and a second position, thereby preventing the movable portion 121 from deviating from its direction of movement and failing to block the feed port 111 or the discharge port 231, thereby ensuring reliable quantitative material removal and single-sided sealing. In this embodiment, the guide portion 24 includes a plurality of bosses 241 spaced apart along the circumference of the discharge port 231. The spaces formed between the bosses 241 match the outer circumference of the movable portion 121, thereby guiding the movement of the movable portion 121. A gap 25 is provided between each movable portion 121 and the guide portion 24, ensuring that material can enter the discharge port 231 through the gap 25 during the movement of the movable portion 121 from the first position to the second position, thereby maintaining communication between the feed port 111 and the discharge port 231.

[0077] This embodiment also provides a method for assembling a hose packaging, which is used to assemble the above-mentioned hose packaging. The method for assembling the hose packaging includes the following steps:

[0078] Step 10, installing the valve core 12 in the valve sleeve 11 to assemble the one-way valve assembly 10;

[0079] Step 20, before sealing the opening of the end of the hose container 20 away from the discharge port 231, install the one-way valve assembly 10 into the hose container 20 from the opening;

[0080] Step 30: seal the opening.

[0081] In this embodiment, the one-way valve assembly 10 is installed in the hose container 20 before the hose container 20 is sealed, and then the hose container 20 is sealed. Therefore, it is not necessary to manufacture the hose container 20 as a structure assembled from multiple parts, which reduces the processing difficulty and facilitates assembly.

[0082] In step 10, the valve core 12 is simply pressed into the valve sleeve 11 from the open end face. In step 20, the entire one-way valve assembly 10 is simply pressed axially along the flexible container 20 until the two engage. In step 30, the opening can be sealed by hot pressing, which requires no additional components, is simple in structure, and provides excellent sealing.

[0083] Obviously, the above embodiments of the present invention are merely examples for the purpose of illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily vary the specific embodiments and scope of application based on the principles of the present invention, and this specification should not be construed as limiting the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the claims.
