Description

Technical Field

[0001] This invention relates to the field of drug delivery container technology, and in particular to a straight-arm rotating opening and closing mechanism and its spray pump and spray container. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to oral health. Many oral symptoms, such as dry mouth, halitosis, oral ulcers, and toothache, are generally caused by oral inflammation or bacterial invasion. Oral ulcers, in particular, should be correctly termed oral mucosal diseases, which refer to changes in the normal color, shape, integrity, and function of the oral mucosa in a certain area. Oral mucosal diseases refer to damage to the oral mucosa, with specific symptoms including: oral ulcers, dry and cracked tongue, hoarseness, dry mouth and bitter taste, which can subsequently lead to oral lichen planus, stomatitis, recurrent aphthous stomatitis, cheilitis, and other oral diseases, resulting in difficulty eating, unbearable oral pain, and significant suffering. Moreover, once the condition develops, it tends to recur.

[0003] There are various methods for treating inflammatory diseases such as oral ulcers, such as oral solid / liquid preparations, sublingual disintegrating tablets, and direct oral sprays. Oral solid / liquid preparations are broken down in the digestive system, absorbed into the bloodstream through the small intestine, and then act on the lesion, resulting in diluted active ingredients, poor efficacy, and a long healing period. Sublingual disintegrating tablets for oral inflammation require a long dissolution time, causing discomfort in the mouth, and are inconvenient for elderly people and children. Therefore, there is an urgent need for a convenient oral spray device that directly targets the ulcer area. To facilitate administration, containers typically use long tubes to deliver the medication directly to the treatment site; however, these long tubes are difficult to store, resulting in poor portability. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a straight-arm rotating opening and closing mechanism and its spray pump and spray container to solve the technical problems of long tube delivery causing long tubes to be difficult to store and carry, as well as the poor sealing of parts in ordinary long tube pumps.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, embodiments of the present invention provide a straight arm rotary opening and closing mechanism, which includes: an outer cover and a rotary arm movably connected to the outer cover;

[0007] The outer cover has a first output channel inside, and the outer cover has a connecting part, with one end of the first output channel extending to the connecting part;

[0008] The rotating arm has a joint, and a second output channel is provided inside the rotating arm, the second output channel passing through the joint;

[0009] The joint is movably connected to the connecting part. When the rotating arm rotates to the first position, the first output channel and the second output channel are aligned and connected. When the rotating arm rotates to the second position, the joint blocks the outlet of the first output channel, thereby disconnecting the first output channel and the second output channel.

[0010] The connecting part is provided with a connecting groove, the bottom of the connecting groove is provided with a first mating surface, the outlet of the first output channel extends to the first mating surface, the joint is provided with a second mating surface, the outlet of the second output channel extends to the second mating surface, the first mating surface and the second mating surface fit together, and in the first position, the first mating surface and the second mating surface abut and seal, and the outlet end of the first output channel and the outlet end of the second output channel are aligned and connected.

[0011] The bottom of the connecting groove is further provided with a guide groove, and the joint is further provided with a guide rail that matches the guide groove, or

[0012] The bottom of the connecting groove is provided with a guide rail, and the joint is provided with a guide groove that matches the guide rail. The guide rail is inserted into the guide groove so that when the rotating arm rotates, it guides the rotating arm to switch between the first position and the second position.

[0013] The guide groove is an open groove extending parallel to the rotation direction of the joint, and the guide rail is a raised rail with an inclined guide surface. The inclined guide surface is used to quickly position and lock the rotating arm after it moves from the second position to the first position.

[0014] Both the first mating surface and the second mating surface are cylindrical surfaces that fit together.

[0015] Both the first mating surface and the second mating surface are mutually fitted spherical surfaces.

[0016] The joint portion is interference-fitted with the connecting groove.

[0017] The connecting groove has a first opening and a second opening that are interconnected. The joint is inserted into the connecting groove through the first opening or the second opening. When the rotating arm is in the first position, the rotating arm is engaged with the first opening. When the rotating arm is in the second position, the rotating arm is engaged with the second opening.

[0018] Secondly, embodiments of the present invention also provide a spray pump, comprising: an outer cover, a pump core connected inside the outer cover, and a straight arm rotating opening and closing mechanism as described above connected outside the outer cover, wherein the outer cover is movable relative to the outer cover along its axial direction, and pressing the outer cover synchronously controls the pump core to pump atomizing agent outward.

[0019] Thirdly, embodiments of the present invention also provide a spray container, which includes: a container bottle and a spray pump as described above connected to the opening of the container bottle, wherein the container bottle is connected to the outer cover.

[0020] The present invention relates to a straight-arm rotating opening and closing mechanism, a spray pump, and a spray container. The straight-arm rotating mechanism employs a rotating arm and an inner conveying channel set within the outer cover. The rotating arm rotates relative to the outer cover by an angle, thereby switching the conveying channel between connected and closed states. When not in use, the rotating arm can be stored in the side wall of the container body, making it easy to carry. Furthermore, the opening and closing mechanism has a simple structure, reliable internal sealing, and is not prone to liquid leakage.

[0021] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, it can be implemented according to the contents of the specification. In order to make the above and other objects, features and advantages of the present invention more obvious and understandable, preferred embodiments are described in detail below.

[0041] Please see Figures 1 to 15 This embodiment provides a spray container 100 with a straight arm rotating opening and closing mechanism. The spray container 100 includes: a container bottle 4, a spray pump connected to the opening of the container bottle 4, and the spray pump includes an outer cover 3 and a straight arm rotating opening and closing mechanism 20 connected to the outer cover 3.

[0042] The straight arm rotating opening and closing mechanism 20 includes: an outer cover 1 and a rotating arm 2 movably connected to the outer cover 1;

[0043] The outer cover 1 is provided with a first output channel 16, and the outer cover 1 has a connecting part 12, one end of the first output channel 16 extends to the connecting part 12;

[0044] The rotating arm 2 has a joint 22, and a second output channel 211 is provided inside the rotating arm 2, the second output channel 211 passing through the joint 22;

[0045] The joint 22 is movably connected to the connecting part 12. When the rotating arm 2 rotates to the first position, the first output channel 16 and the second output channel 211 are aligned and connected. When the rotating arm 2 rotates to the second position, the joint 22 blocks the outlet of the first output channel 16, so that the first output channel 16 and the second output channel 211 are disconnected.

[0046] It should be noted that this embodiment uses a spray container bottle as an example to describe the structure of the straight arm rotating opening and closing mechanism 20. In other embodiments, the outer cover 1 and the rotating arm 2 may correspond to other functional structural components, such as the first structural component and the second structural component, and are not limited to the components of this embodiment.

[0047] In this embodiment, the outer cover 1 and the rotating arm 2 of the straight arm rotating opening and closing mechanism 20 can rotate relative to each other to achieve switching from the first position to the second position. In the first position and the second position, the outer cover 1 and the rotating arm 2 are in different states, which facilitates quick switching from the use state to the storage state.

[0048] Please refer to it again. Figures 8 to 11 The connecting part 12 is provided with a connecting groove 121, and the bottom of the connecting groove 121 is provided with a first mating surface 122. The outlet 161 of the first output channel 16 extends to the first mating surface 122. The joint part 22 is provided with a second mating surface 220, and the outlet 221 of the second output channel 211 extends to the second mating surface 220. The first mating surface 122 and the second mating surface 220 fit together. In the first position, the first mating surface 122 and the second mating surface 220 abut and seal. The outlet 161 end of the first output channel 16 is aligned and connected with the outlet 221 end of the second output channel 211. Conversely, when the two are in the second position, the first output channel 16 and the second output channel 211 are disconnected, which corresponds to the storage state.

[0049] The outer cover 1 includes: a pressing part 11, an annular wall 13 extending from the edge of the pressing part 11, and a connecting part 12. The pressing part 11 is a circular plate, and the pressing part 11 and the annular wall 13 together form a cover-shaped structure, with a connecting cavity 10 inside. An axially extending connecting pipe 15 is also provided on the inner side of the pressing part 11. The first output channel 16 is connected to the side wall of the connecting pipe 15 and is internally interconnected. The connecting pipe 15 is used to connect to the outlet end of the pump core 5. The first output channel 16 extends radially along the inner side of the pressing part 11 to the first mating surface 122.

[0050] like Figure 11As shown, the rotating arm 2 includes: a straight arm portion 21, and a joint portion 22 connected to one end of the straight arm portion 21. The straight arm portion 21 has a second output channel 211, and the outlet 221 of the second output channel 211 extends to the surface of the joint portion 22, specifically to the surface of the second mating surface 220. The joint portion 22 can rotate within the connecting groove 121. When the first mating surface 122 and the second mating surface 220 are in different contact states, the first output channel 16 and the second output channel 211 switch between connected and disconnected states.

[0051] The first output channel 16 is also equipped with a water core 6, which is used to atomize the medicine pumped by the pump core 5.

[0052] In order to ensure that the first output channel 16 and the second output channel 211 can be accurately aligned, the bottom of the connecting groove 121 is provided with a guide rail 123, and the joint 22 is provided with a guide groove 222 that matches the guide rail 123. The guide rail 123 is inserted into the guide groove 222 so that when the rotating arm 2 rotates, it guides the rotating arm 2 to switch between the first position and the second position.

[0053] In another embodiment, the positions of the guide groove 222 and the guide rail 123 on the connecting portion 12 and the joint portion 22 can be interchanged.

[0054] A structure is provided between the connecting part 12 and the joint part 22, with a guide groove 222 and a guide rail 123 that are mutually connected to guide each other. This structure is used to limit the relative rotation direction between the rotating arm 2 and the upper cover 1. In the determined rotation direction, the first output channel 16 and the second output channel 211 can be accurately aligned and connected.

[0055] In this embodiment, the guide groove 222 is an open groove extending parallel to the rotation direction of the joint 22. There are two such open grooves, which are arranged parallel to each other, and the second mating surface 220 is located between the two open grooves. The guide rail 123 is a raised rail with an inclined guide surface 1231, which is used to quickly position and lock the rotating arm 2 after it moves from the second position to the first position.

[0056] In this embodiment, the mating surface of the guide rail 123 is configured with an inclined guide surface 1231 to limit the rotation angle between the rotating arm 2 and the outer cover 1, thereby further improving the accuracy of their alignment and connection. The first and second positions of rotation between the rotating arm 2 and the outer cover 1 are more specific. When the user operates the rotating arm 2, it can quickly switch between the first and second positions without being locked at other rotation angles, which would prevent it from correctly entering the use or storage state.

[0057] In this embodiment, both the first mating surface 122 and the second mating surface 220 are mutually fitting cylindrical surfaces. It should be noted that the first mating surface 122 and the second mating surface 220 are partial surface shapes of the connecting groove 121 and the joint portion 22, not their entire shapes; that is, the second mating surface 200 on the joint portion 22 is at least partially a cylindrical surface. Similarly, the bottom of the connecting groove 121 is at least partially a cylindrical surface of the second mating surface 220. It is understood that the joint portion 22 can also be an integral cylindrical structure.

[0058] In another embodiment, both the first mating surface 122 and the second mating surface 220 are mutually abutting spherical surfaces. Since the joint portion 22 and the connecting groove 121 in this embodiment need to remain in close contact at all times to ensure a sealed state between their mating surfaces (they are only open and connected in the first position), the first mating surface 122 and the second mating surface 220 can also be mutually abutting spherical surfaces. Similarly, the spherical surface is at least a partial surface shape of the connecting groove 121 and the joint portion 22; of course, the spherical surface can be hemispherical or a complete sphere.

[0059] In this embodiment, the joint portion 22 is interference-fitted with the connecting groove 121. The joint portion 22 can be made of a material with a certain degree of elasticity, and the elastic contact between the two will result in better sealing.

[0060] Please refer to it again. Figure 9 The connecting groove 121 has a first opening 125 and a second opening 126 that are interconnected. The joint 22 is inserted into the connecting groove 121 through the first opening 125 or the second opening 126. That is, the straight arm 21 extends out of the connecting groove 121 through the connecting part 12. When the rotating arm 2 is in the first position, the rotating arm 2 is engaged with the first opening 125. When the rotating arm 2 is in the second position, the rotating arm 2 is engaged with the second opening 126. In this embodiment, the rotating arm 2 is the long tube referred to in the background art, used to accurately deliver the drug to the lesion location.

[0061] In this embodiment, the first position and the second position are at a 90° angle, that is, the straight arm 21 can switch from a horizontal state to a vertical state relative to the outer cover 1.

[0062] This invention also provides a spray pump, comprising: an outer cover 3, a pump core 5 connected inside the outer cover 3, and a straight-arm rotating opening and closing mechanism 20 as described above, connected outside the outer cover 3. The outer cover 1 is movable relative to the outer cover 3 along its axial direction, and pressing the outer cover 1 synchronously controls the pump core 5 to pump atomizing agent outward. The pump core 5 is a conventional spray pump core, and its structure will not be described in detail here.

[0063] Please refer to it again. Figure 6 and Figure 7 The outer cover 3 includes a tubular body 31, and a connecting wall 32 is provided inside the cavity of the tubular body 31 for connecting the pump core 5. The side wall of the tubular body 31 is also provided with a front opening 35 and a rear opening 33. The rear opening 33 is used to allow the connecting part 12 to extend when the outer cover 1 is assembled. An arc-shaped protrusion 14 protrudes from the annular wall 13 of the outer cover 1 near the pressing part 11. The radius of the arc-shaped protrusion 14 is slightly larger than the radius of the cavity of the tubular body 31 of the outer cover 3. When the outer cover 1 is pressed and moves axially downward, the arc-shaped protrusion 14 abuts against the lower edge of the front opening 35, and the outer cover 1 is stopped, thereby limiting the pressing stroke of the outer cover 1.

[0064] To prevent the outer cover 1 from rotating relative to the outer cover 3 when pressed, the inner wall of the tubular body 31 of the outer cover 3 is provided with an axially extending protruding limiting plate 34. Correspondingly, the annular wall 13 of the outer cover 1 is provided with a guide groove 131. The limiting plate 34 is inserted into the guide groove 131 to guide the pressing and moving direction of the outer cover 1.

[0065] This invention also provides a spray container 100, which includes: a container bottle 4 and a spray pump as described above connected to the opening of the container bottle 4, wherein the container bottle 4 is connected to the outer cover 3.

[0066] Please refer to it again. Figure 14 and Figure 15 , Figure 14 When the rotating arm 2 and the outer cover 1 are in the first position, that is, when the first output channel 16 and the second output channel 211 are connected, the rotating arm 2 and the outer cover 1 are approximately parallel, and the opening 161 of the first output channel 16 and the opening 221 of the second output channel 211 are aligned and connected. When the rotating arm 2 rotates to the second position, that is, when... Figure 15 In the indicated position, the rotating arm 2 and the outer cover 1 are approximately perpendicular to each other. At this time, the second mating surface 220 of the joint 22 of the rotating arm 2 (excluding the opening) partially blocks the outlet 161 of the first output channel 16 inside the outer cover 1. The first output channel 16 and the second output channel 211 are disconnected, and atomizing agent cannot be pumped outward. It should be noted that the joint 22 and the connecting groove 121 are connected to the first output channel 16 and the second output channel 211 only when they are in the first position; otherwise, they are sealed. Furthermore, when they are in the second position, they are also sealed at the contact surface.

[0067] The straight-arm rotating opening and closing mechanism, spray pump, and spray container of this embodiment are characterized by a conveying channel set inside the rotating arm and the outer cover. The rotating arm rotates relative to the outer cover by an angle, thereby switching the conveying channel between the connected and closed states. When not in use, the rotating arm can be stored in the side wall of the container body, making it easy to carry. Moreover, the opening and closing mechanism has a simple structure, reliable internal sealing, and is not prone to liquid leakage.

[0068] The above examples are merely illustrative of the technical content of the present invention to facilitate easier understanding by the reader, but do not imply that the implementation of the present invention is limited to these examples. Any technical extensions or re-creations made based on the present invention are protected by the present invention. The scope of protection of the present invention is defined by the claims.
