Description

Technical Field

[0001] This utility model relates to the field of nasal spray technology, and in particular to a child-proof opening structure for a nasal spray. Background Technology

[0002] Nasal sprays are devices used to spray medication into the nasal cavity. The medication is dispensed by pressing a button. Current nasal spray nozzles have a dust cap that clips onto the outside of the nozzle, primarily for dust prevention. However, this dust cap, being clipped on, is prone to falling off, leading to medication waste, infection, and potential accidental ingestion or aspiration by children, posing a health risk. Utility Model Content

[0003] This invention provides a child-proof opening structure for nasal sprays, aiming to solve the problem that the dust cap of nasal sprays in the prior art is easily separated from the nozzle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a child-proof opening structure for a nasal spray, comprising: a bottle body, a nozzle disposed on the bottle body, and a dust cover sleeved on the outside of the nozzle; The outer wall of the nozzle is provided with a slot along the first radial direction, and the inner wall of the dust cover is provided with a buckle that cooperates with the slot. The dust cover is provided with a pressing part along the second radial direction, and a gap is provided between the inner side wall of the pressing part and the outer side wall of the nozzle; pressing the dust cover along the second radial direction causes the dust cover to deform along the first radial direction, so that the buckle separates from the slot.

[0005] In one embodiment, the first radial direction and the second radial direction are perpendicular to each other.

[0006] In one embodiment, two slots are provided, and the two slots are arranged on both sides of the outer wall of the nozzle along a first radial direction.

[0007] In one embodiment, the dust cover has a positioning groove at its opening; the nozzle has a positioning protrusion that mates with the positioning groove on its periphery.

[0008] In one embodiment, two positioning protrusions are provided, and the two positioning protrusions are arranged on both sides of the outer wall of the nozzle along a first radial direction.

[0009] In one embodiment, the outer wall of the dust cover is provided with an marking portion for marking a second radial direction.

[0010] In one embodiment, the marking portion is provided with a pattern for increasing friction.

[0011] In one embodiment, the dust cover is provided with a safety structure for limiting the extrusion deformation of the dust cover along the second radial direction.

[0012] In one embodiment, the safety structure includes a limiting slide bar slidably disposed inside the dust cover; the dust cover has a through groove disposed along the axial direction, and the limiting slide bar is fixedly connected to a limiting slider that slides along the through groove; pushing the limiting slider along the through groove causes the limiting slide bar to engage or disengage with the clearance.

[0013] In one embodiment, the inner wall of the dust cover is provided with a limiting groove, and the limiting slide is slidably disposed in the limiting groove; a receiving groove is provided at a position away from the through groove in the limiting groove; a filling block is provided at the end of the limiting slide away from the limiting slider; a first inclined surface is provided on the receiving groove, and a second inclined surface is provided on the filling block; when the limiting slide is pushed to move toward the gap, the second inclined surface of the filling block is inserted into the gap along the first inclined surface.

[0014] The advantages of this utility model compared with the prior art are as follows: This utility model provides a slot and a buckle in the first radial direction and a pressing part in the second radial direction. By pressing the dust cover along the second radial direction, the gap between the dust cover and the nozzle is reduced or eliminated, allowing the dust cover to expand outward along the first radial direction, thereby separating the buckle from the slot and thus separating the dust cover from the nozzle.

[0015] In addition, this embodiment also includes a safety structure. When activated, the safety structure can limit the deformation of the dust cover under pressure along the second radial direction, thereby preventing the dust cover from deforming along the first radial direction and preventing the buckle from separating from the slot. This prevents the dust cover from separating from the nozzle due to accidental pressing of the pressing part, making it safer and more reliable to use.

[0016] Therefore, this utility model has the advantages of simple structure and convenient use, and can effectively prevent children from opening the dust cover, thus protecting children and preventing drug leakage.

[0017] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model, it can be implemented according to the contents of the specification. In order to make the above and other objects, features and advantages of this utility model more obvious and understandable, the following are preferred embodiments, which are described in detail below.

[0024] Please see Figure 1-6 This utility model provides a child-proof opening structure for a nasal spray, comprising: a bottle body 1, a nozzle 2 disposed on the bottle body 1, and a dust cover 3 sleeved on the outside of the nozzle 2; like Figure 3 and Figure 4 As shown, the outer side wall of the nozzle 2 is provided with a slot 21 along the first radial direction, and the inner side wall of the dust cover 3 is provided with a buckle 31 that cooperates with the slot 21; like Figure 5 and Figure 6 As shown, the dust cover 3 is provided with a pressing part 32 along the second radial direction, and a gap 4 is provided between the inner side wall of the pressing part 32 and the outer side wall of the nozzle; pressing the dust cover 3 along the second radial direction causes the dust cover 3 to deform along the first radial direction, and the buckle 31 separates from the slot 21.

[0025] In this embodiment, the first radial direction is perpendicular to the outer wall of the dust cover 3 corresponding to the slot 21. Specifically, as shown in the figure... Figure 3 As shown, the first radial direction is the direction indicated by the arrows on both sides of the dust cover 3. The second radial direction is the direction perpendicular to the pressing part 32, specifically, as shown... Figure 5 As shown, the second radial direction is the direction indicated by the arrows on both sides of the dust cover 3.

[0026] In this invention, a slot 21 and a buckle 31 are provided in the first radial direction, while a pressing part 32 is provided in the second radial direction. By pressing the dust cover 3 along the second radial direction, the gap 4 between the dust cover 3 and the nozzle 2 is reduced or eliminated, allowing the dust cover 3 to expand outward along the first radial direction. This causes the buckle 31 to separate from the slot 21, thereby separating the dust cover 3 from the nozzle 2. This embodiment has a simple structure and is easy to use. It can effectively prevent children from opening the dust cover 3, thus protecting children and preventing drug leakage.

[0027] In a further embodiment, the first radial direction and the second radial direction are perpendicular to each other.

[0028] In this embodiment, the first radial direction and the second radial direction are perpendicular, so that when the second radial direction is pressed, the deformation of the first radial direction is the largest, making it easier for the buckle 31 to separate from the slot 21.

[0029] In a further embodiment, such as Figure 3 As shown, there are two slots 21, which are arranged along the first radial direction on both sides of the outer wall of the nozzle 2.

[0030] In this embodiment, two slots 21 are provided, and two buckles 31 cooperate with the slots 21. This not only allows the dust cover 3 to be firmly attached to the nozzle 2, but also allows the dust cover 3 to deform simultaneously towards both sides of the first radial direction when the dust cover 3 is pressed along the second radial direction, so that the buckles 31 on both sides separate from the slots 21 at the same time.

[0031] In a further embodiment, the dust cover 3 has a positioning groove 33 at its opening; the nozzle 2 has a positioning protrusion 22 that cooperates with the positioning groove 33 on its periphery.

[0032] The engagement of the positioning groove 33 and the positioning protrusion 22 allows the dust cover 3 to be positioned relative to the nozzle 2. When the dust cover 3 is placed on the nozzle 2 through the engagement of the positioning groove 33 and the positioning protrusion 22, the positions of the latch 31 and the slot 21 are precisely aligned. Furthermore, the engagement of the positioning groove 33 and the positioning protrusion 22 also restricts the rotation of the dust cover 3 on the nozzle 2, preventing the latch 31 from separating from the slot 21 by rotating the dust cover 3.

[0033] In a further embodiment, two positioning protrusions 22 are provided, and the two positioning protrusions 22 are arranged on both sides of the outer side wall of the nozzle 2 along a first radial direction.

[0034] Two positioning protrusions 22 and two positioning grooves 33 are provided on the dust cover 3 to make it easier for the dust cover 3 to fit with the nozzle 2. At the same time, the limiting effect of the dust cover 3 in the circumferential direction is better.

[0035] In a further embodiment, the outer wall of the dust cover 3 is provided with an marking portion 34 for marking the second radial direction, and the marking portion 34 is provided with a pattern for increasing friction.

[0036] The marking section 34 can remind the user to press the dust cover 3 in this direction. At the same time, the pattern can increase the friction between the finger and the dust cover 3, making it easier to pull the dust cover 3 off the nozzle 2 by hand.

[0037] In a further embodiment, such as Figures 7 to 11 As shown, a safety structure for limiting the extrusion deformation of the dust cover 3 along the second radial direction is also provided on the dust cover 3.

[0038] When activated, the safety structure in this application can limit the deformation of the dust cover 3 under pressure along the second radial direction, so that the dust cover 3 cannot deform along the first radial direction, thereby preventing the buckle 31 from separating from the slot 21, thus preventing the dust cover 3 from separating from the nozzle 2 due to accidental pressing of the pressing part 32.

[0039] In a further embodiment, such as Figure 7 and Figure 8 As shown, the safety structure includes a limiting slide bar 5 slidably disposed inside the dust cover 3; a through groove 35 disposed along the axial direction is provided through the dust cover 3, and a limiting slider 51 that slides along the through groove 35 is fixedly connected to the limiting slide bar 5; pushing the limiting slider 51 along the through groove 35 causes the limiting slide bar 5 to engage or disengage with the gap 4.

[0040] In this embodiment, the limiting slider 51 is slidably disposed inside the limiting slider 5, and the limiting slider 51 protrudes from the surface of the dust cover 3, so that the limiting slider 51 can be pushed from the outside of the dust cover 3.

[0041] like Figure 8 and Figure 9 As shown, when the safety structure needs to be activated, the limiting slider 51 is pushed, causing the limiting slider 51 to slide downward along the through groove 35, so that the end of the limiting slider 5 slides to the gap 4 between the inner side wall of the pressing part 32 and the outer side wall of the nozzle 2. This restricts the dust cover 3 from pressing along the second radial direction, so that the dust cover 3 cannot deform along the first radial direction, thus preventing the buckle 31 from separating from the slot 21. This prevents the dust cover 3 from separating from the nozzle 2 due to accidental pressing of the pressing part 32.

[0042] When the safety structure needs to be released, push the limiting slider 51 so that the limiting slider 51 slides upward along the through groove 35, so that the end of the limiting slider 5 disengages from the gap 4 between the inner side wall of the pressing part 32 and the outer side wall of the nozzle 2, thereby allowing the dust cover 3 to be pressed along the second radial direction, so that the dust cover 3 can be deformed along the first radial direction, thereby allowing the buckle 31 to separate from the slot 21, and thus allowing the dust cover 3 to be smoothly separated from the nozzle 2.

[0043] In a further embodiment, the limiting slider 51 is interference-fitted with the through groove 35, so that the limiting slider 51 can be fixed in the through groove 35, thereby allowing the limiting slider 5 to remain filled in the gap 4, so that the safety state can be maintained continuously.

[0044] In a further embodiment, in order to prevent the wall thickness of the dust cover 3 from increasing due to the setting of the limiting slide bar 5, or to reduce the size of the gap 4 between the inner wall of the pressing part 32 and the outer wall of the nozzle 2.

[0045] In this embodiment, as Figure 10 and Figure 11 As shown, a limiting groove 36 is provided on the inner side wall of the dust cover 3, and the limiting slide bar 5 is slidably disposed in the limiting groove 36; a receiving groove 37 is provided at the position of the limiting groove 36 away from the through groove 35; a filling block 52 is provided at the end of the limiting slide bar 5 away from the limiting slider 51; a first inclined surface 371 is provided on the receiving groove 37, and a second inclined surface 521 is provided on the filling block 52; when the limiting slide bar 5 is pushed to move towards the gap 4, the second inclined surface 521 of the filling block 52 is inserted into the gap 4 along the first inclined surface 371.

[0046] By setting the filling block 52 and the receiving groove 37, when the safety structure is released, the filling block 52 can be stored in the receiving groove 37, thus not affecting the size of the gap 4, allowing the dust cover 3 to be pressed smoothly along the second radial direction. When the safety structure is activated, when the limiting slider 5 slides, the second inclined surface 521 of the filling block 52 and the first inclined surface 371 of the receiving groove 37 cooperate, allowing the filling block 52 to slide into the gap 4, thereby restricting the dust cover 3 from being pressed along the second radial direction, preventing the dust cover 3 from deforming along the first radial direction, and thus preventing the buckle 31 from separating from the slot 21, thereby preventing the dust cover 3 from separating from the nozzle 2 due to accidental pressing of the pressing part 32.

[0047] In a further embodiment, the outer wall of the limiting slider 51 is provided with a plurality of protruding ridges 511 for increasing friction.

[0048] In this embodiment, a protruding ridge 511 is provided, which allows the limit slider 51 to be easily slid by hand, thereby making it easier to activate and deactivate the safety structure.

[0049] In this invention, a slot 21 and a buckle 31 are provided in the first radial direction, and a pressing part 32 is provided in the second radial direction. By pressing the dust cover 3 along the second radial direction, the gap 4 between the dust cover 3 and the nozzle 2 is reduced or disappears, allowing the dust cover 3 to expand outward along the first radial direction, thereby separating the buckle 31 from the slot 21, and thus separating the dust cover 3 from the nozzle 2.

[0050] In addition, this embodiment also includes a safety structure. When activated, the safety structure can limit the deformation of the dust cover 3 under pressure along the second radial direction, preventing the dust cover 3 from deforming along the first radial direction. This prevents the buckle 31 from separating from the slot 21, thus preventing the dust cover 3 from separating from the nozzle 2 due to accidental pressing of the pressing part 32, making it safer and more reliable to use.

[0051] Therefore, this utility model has the advantages of simple structure and convenient use, and can effectively prevent children from opening the dust cover 3, thus protecting children and preventing drug leakage.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
