[0019] The beneficial effects of the present invention are: The one-way valve assembly of the present invention is installed in a hose container. When it is necessary to take material from the hose container, the hose container is squeezed, and the material in the hose container is subjected to pressure to enter the feed port and push the movable part, thereby causing the movable part to move from the first position to the second position. At this time, the feed port and the discharge port are connected, and the material can enter the installation space from the feed port and be further discharged from the discharge port. When the movable part moves to the second position, it will block the discharge port. At this time, if the hose container is squeezed hard again, the material in the hose container will not be discharged anymore.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of convenience of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0025] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0027] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0028] This embodiment provides a one-way valve assembly and a hose package, and the hose package includes this one-way valve assembly.

[0029] As Figures 1-3As 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 pipe 23. The container body 21 is used to hold the material, and a discharge port 231 is provided on the discharge pipe 23. In this embodiment, the hose container 20 is made of a material with a certain elastic deformation ability. Therefore, when the user squeezes the container body 21, the material in the container body 21 can be discharged from the discharge port 231. In this embodiment, the hose container 20 is made of PE material, and the PE material has a lower hardness, making it more convenient for the user to perform the squeezing operation. The cap 30 is used to cover one end of the discharge pipe 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 material in the hose container 20.

[0030] As Figure 2 shown, in this embodiment, the container body 21 is generally a columnar structure, and the discharge pipe 23 is a columnar structure with a certain taper, and the diameter of the container body 21 is greater than the maximum diameter of the discharge pipe 23. In some embodiments, the hose container 20 further includes a transition pipe 22. The transition pipe 22 is arranged between the container body 21 and the discharge pipe 23, and the diameter of the transition pipe 22 is smaller than the diameter of the container body 21 and greater than the maximum diameter of the discharge pipe 23. On the one hand, by providing the transition pipe 22, the cross-section inside the hose container 20 forms a transition, which facilitates extrusion even when the material remaining in the hose container 20 is less. On the other hand, outside the hose container 20, a table surface is formed between the container body 21 and the transition pipe 22. After the cap 30 is covered on the hose container 20, it abuts against this table surface. This table surface not only plays a role in limiting the installation of the cap 30, but also makes the overall shape of the hose packaging regular and smooth. In this embodiment, the container body 21, the transition pipe 22 and the discharge pipe 23 are integrally formed. Such a setting is not only convenient for processing, but also has good sealing performance.

[0031] As Figures 2-4 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 seal the discharge port 231, preventing the material in the hose container 20 from oxidizing and deteriorating. In addition, during the storage or transportation of the product using this hose packaging, if the hose container 20 is accidentally squeezed, the sealing plug 32 can prevent the material in the hose container 20 from being extruded.

[0032] As Figures 2-4As shown, a guide sleeve 33 is provided on the cap 30. When the cap 30 is placed on the hose container 20, the portion of the hose container 20 where the discharge port 231 is provided (i.e., the end of the discharge pipe 23) is inserted into the guide sleeve 33. By providing the guide sleeve 33, it can play a guiding role in the installation of the cap 30, thereby ensuring that the plug 32 can be smoothly inserted and block the discharge port 231, improving the convenience of installing the cap 30. In this embodiment, the guide sleeve 33 is disposed around the outer periphery of the plug 32.

[0033] As Figures 2-4 shown, a first threaded portion 31 is provided on the inner wall of the cap 30, and a second threaded portion 221 is provided on the outer periphery of the hose container 20. The first threaded portion 31 is threadedly connected to the second threaded portion 221. The threaded connection between the cap 30 and the hose container 20 not only has good connection reliability but also can play a certain sealing role, 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 periphery of the transition pipe 22, so that after the first threaded portion 31 is threadedly connected to the second threaded portion 221, the end face of the cap 30 just abuts against the end face between the container body 21 and the transition pipe 22. Of course, in other embodiments, the cap 30 and the hose container 20 can also be connected by a snap connection method, which is not limited here. In this embodiment, the cap 30 is made of PP material. The PP material has sufficient hardness and is not easily deformed, so its cooperation with the hose container 20 can ensure the connection reliability and also ensure the sealing effect on the discharge port 231.

[0034] When using the hose container 20 to extrude the material, it is difficult to control the force, resulting in problems such as excessive extrusion at one time, affecting the user experience; in addition, during actual use, it is also easy to occur that the cap 30 is lost or the user forgets to cover 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.

[0035] In response to this, as Figure 5 and Figure 6 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 in the hose container 20 and forms an installation space 40 with the inner wall of the hose container 20. The valve sleeve 11 is provided with a feed port 111, and the feed port 111 communicates the installation space 40 and the inner cavity of the hose container 20. The discharge port 231 communicates with the installation space 40. The valve core 12 is disposed in the installation space 40 and includes a movable portion 121. The movable portion 121 can move between a first position and a second position. When the movable portion 121 is in the first position, it blocks the feed port 111. When it is in the second position, it blocks the discharge port 231. When it is between the first position and the second position, it makes the feed port 111 and the discharge port 231 communicate.

[0036] When it is necessary to take materials from the hose container 20, the hose container 20 is squeezed. The materials in the hose container 20 are under pressure and will 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 communicated, and the materials 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 will block the discharge port 231. At this time, if the hose container 20 is squeezed forcefully again, the materials in the hose container 20 will no longer be discharged. Since the stroke of the movable part 121 moving from the first position to the second position is fixed, the discharge amount of the materials is certain each time the hose container 20 is pressed, realizing the function of quantitative discharging and improving the convenience and accuracy of the user to take materials; when the hose container 20 is no longer squeezed, the external atmospheric pressure pushes the movable part 121 to reset from the second position to the first position. At this time, the movable part 121 blocks the feed port 111, so that the materials in the hose container 20 can be sealed, and the continuous entry of external pollutants into the hose container 20 to contaminate the materials can be avoided.

[0037] Optionally, in this embodiment, the hardness of the valve sleeve 11 is greater than that of the valve core 12. The valve sleeve 11 is made of a material with a relatively high hardness, which can avoid its random deformation and ensure that the discharge amount of the materials remains unchanged during the process of the movable part 121 moving from the first position to the second position. The valve core 12 is made of a material with a relatively low hardness, which is convenient for the movable part 121 to move smoothly from the first position to the second position when the user squeezes the hose container 20, and for the movable part 121 to reset smoothly from the second position to the first position under the action of the atmospheric pressure after the squeezing of the hose container 20 is completed. Optionally, in this embodiment, the valve sleeve 11 is made of PP material and the valve core 12 is made of PE material.

[0038] In this embodiment, as Figures 5-7 shown, the valve sleeve 11 is generally a cylindrical structure. One end of the valve sleeve 11 close to the discharge pipe 23 is in an open state, so that the valve core 12 can be smoothly installed into the valve sleeve 11. One end of the valve sleeve 11 far from the discharge port 231 has an end plate 114, and the feed port 111 is opened on the end plate 114. The valve sleeve 11 is installed in the transition pipe 22 and abuts against the surface between the transition pipe 22 and the discharge pipe 23, so as to enclose and form the installation space 40.

[0039] As Figure 5 and Figure 6As shown in the figure, a protrusion 113 is provided on the outer periphery of the valve sleeve 11, and a mating groove 222 is provided on the inner wall of the hose container 20. The protrusion 113 is snapped into the mating groove 222, thereby realizing the connection between the valve sleeve 11 and the hose container 20. In this embodiment, the mating groove 222 is opened on the inner wall of the transition pipe 22. The protrusion 113 is circumferentially arranged around the valve sleeve 11 for one week. Correspondingly, the mating groove 222 is circumferentially arranged around the inner wall of the transition pipe 22 for one week, thereby ensuring the reliability of the connection between the valve sleeve 11 and the hose container 20. In other embodiments (not shown), it is also possible that a groove is provided on the valve sleeve 11 and a protrusion is provided on the hose container 20, and the fixing of the valve sleeve 11 is realized by the snap connection between the protrusion and the groove, which is not limited herein.

[0040] As Figures 5-8 shown in the figure, the valve core 12 further 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 can elastically deform so that the movable portion 121 moves from the first position to the second position. In this embodiment, the reciprocating movement of the movable portion 121 is realized by the local elastic deformation of the valve core 12 itself, and the structure is simple and the cost is low. In this embodiment, the mounting portion 122, the connecting portion 123 and the movable portion 121 are integrally formed, which is not only convenient for molding, but also the connection positions of the connecting portion 123 with the mounting portion 122 and the movable portion 121 are not easily damaged.

[0041] In this embodiment, the mounting portion 122 is configured as a cylinder, the movable portion 121 is arranged inside the mounting portion 122 and forms a gap with the mounting portion 122, and the connecting portion 123 is arranged along the radial direction of the valve core 12. Therefore, before the movable portion 121 leaves the first position and has not reached the second position, the material in the hose container 20 can enter the gap between the mounting portion 122 and the movable portion 121 from the feed port 111, and then further enter the discharge port 231.

[0042] As Figure 5 and Figure 7 shown in the figure, among the outer peripheral surface of the mounting portion 122 and the inner peripheral surface of the valve sleeve 11, one of them is provided with a card slot 112, and the other is provided with a card protrusion 1221. The card slot 112 and the card protrusion 1221 are in snap-fit. The fixing installation of the valve core 12 and the valve sleeve 11 can be realized through the cooperation of the card slot 112 and the card protrusion 1221, and the structure is simple and the assembly is convenient. In this embodiment, the card protrusion 1221 is provided on the outer peripheral surface of the mounting portion 122, and the card slot 112 is provided on the inner peripheral surface of the valve sleeve 11. Optionally, the card protrusion 1221 is circumferentially arranged around the outer periphery of the mounting portion 122 for one week, and the card slot 112 is circumferentially arranged around the inner periphery of the valve sleeve 11 for one week, so the reliability of the connection between the valve core 12 and the valve sleeve 11 can be ensured.

[0043] As Figure 8As shown, at least two connecting parts 123 are provided, and the at least two connecting parts 123 are arranged at intervals and evenly along the circumferential direction of the mounting part 122. Such an arrangement ensures uniform force on the movable part 121 in the circumferential direction. Therefore, when the user squeezes the hose container 20, the moving direction of the movable part 121 will not be skewed, and thus it can accurately reach the second position and block the discharge port 231.

[0044] In this embodiment, as Figure 8 shown, the valve core 12 includes three connecting parts 123. In other embodiments, the specific number of the connecting parts 123 can be flexibly set according to requirements and will not be limited here. Optionally, the connecting part 123 includes an extension section 1232 and two connecting ends 1231. 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 part 122, and the other connecting end 1231 is connected to the movable part 121. The extension section 1232 extends along the circumferential direction of the valve core 12. Such an arrangement can increase the length of the extension section 1232 under the condition that the overall radial dimension of the valve core 12 is certain, so as to ensure that the connecting part 123 as a whole has sufficient deformation to meet the use requirements.

[0045] As Figure 7 and Figure 8 shown, the movable part 121 is generally a shaft-like 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 part 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.

[0046] As Figure 5 and Figure 8 shown, the movable part 121 includes a first sealing surface 1211. The first sealing surface 1211 is arranged at one end of the movable part 121 facing the feed port 111. The first sealing surface 1211 is an arc surface and protrudes from the lower surface of the mounting part 122 (the surface of the mounting part 122 facing the end plate 114 of the valve sleeve 11). When the movable part 121 is in the first position, the movable part 121 elastically presses against the end surface of the feed port 111, and the first sealing surface 1211 partially extends into the feed port 111. By providing the first sealing surface 1211 and the elastic pressing of the movable part 121 against the end surface of the feed port 111, the reliability of the movable part 121 in sealing the feed port 111 can be improved. Optionally, in this embodiment, the first sealing surface 1211 can be a spherical surface.

[0047] As Figure 5 and Figure 7As shown, the movable part 121 further includes a second sealing surface 1212. The second sealing surface 1212 is disposed at one end of the movable part 121 facing the discharge port 231. The second sealing surface 1212 is an arc surface. When the movable part 121 is in the second position, the second sealing surface 1212 at least partially extends into the discharge port 231. By setting the second sealing surface 1212 as an arc surface, when the user squeezes the hose container 20, a part of the second sealing surface 1212 can extend into the discharge port 231, thereby preventing the movable part 121 from being skewed during movement, ensuring the reliability of the sealing of the discharge port 231 by the movable part 121, and further ensuring the accuracy of quantitative material taking.

[0048] As Figure 5 and Figure 9 shown, a guiding part 24 is disposed in the hose container 20. The guiding part 24 is disposed around the discharge port 231. The guiding part 24 is configured to guide the movement of the movable part 121 between the first position and the second position, thereby preventing the movement direction of the movable part 121 from being skewed and unable to seal the inlet port 111 or the discharge port 231, and ensuring the reliability of quantitative material taking and unilateral sealing. In this embodiment, the guiding part 24 includes a plurality of bosses 241 spaced circumferentially along the discharge port 231. The space formed by enclosing between the respective bosses 241 matches the outer peripheral dimension of the movable part 121, so as to guide the movement of the movable part 121. There is a gap 25 between each movable part 121 and the guiding part 24, so as to ensure that during the process of the movable part 121 moving from the first position to the second position, the material can enter the discharge port 231 from the gap 25, that is, ensuring that the inlet port 111 and the discharge port 231 are in a communicating state.

[0049] This embodiment also provides an assembling method for a hose package for assembling the above-mentioned hose package. The assembling method of the hose package includes the following steps: Step 10: Install the valve core 12 in the valve sleeve 11 to assemble a one-way valve assembly 10; Step 20: Before sealing the opening at one end of the hose container 20 facing away from the discharge port 231, install the one-way valve assembly 10 into the hose container 20 from the opening; Step 30: Seal the opening.

[0050] In this embodiment, the one-way valve assembly 10 is installed into 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 by multiple components, and the processing difficulty is low and the assembly is convenient.

[0051] In step 10, the valve core 12 can be directly pressed into the valve sleeve 11 from the open end face of the valve sleeve 11. In step 20, the entire one-way valve assembly 10 can be directly pressed along the axial direction of the hose container 20 until they are clamped. In step 30, the opening can be sealed by hot pressing. This method does not require additional components, has a simple structure and good sealing performance.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation on the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
