Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of drug spray devices, specifically relating to a child-protective nasal spray device with a safety lock function. Background Technology
[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.
[0003] A nasal spray device is a medical device or packaging material that can spray medication in a mist form, allowing the drug droplets to act directly on the patient's nasal passages for highly effective drug delivery. Nasal spray devices typically include a push button, a nasal spray pump, and a vial. Current nasal spray devices have the following drawbacks:
[0004] (1) The push button and nasal spray pump of the nasal spray preparation device can be separated, which poses a risk of accidental injury or ingestion by children.
[0005] (2) Nasal spray formulations have two manufacturing processes for the nasal spray pump and the vial: screw-sealed and crimp-sealed. The screw-sealed process allows for unscrewing during use, posing a safety hazard to children who may accidentally ingest the medication. The crimp-sealed process provides a good seal that cannot be separated, but it can generate aluminum shavings during the filling process, potentially posing a safety risk to patients and product quality. Furthermore, crimp-sealed nasal sprays involve more filling steps and more complex material control than screw-sealed nasal sprays, increasing production costs. Utility Model Content
[0006] The purpose of this invention is to provide a nasal spray device that has both a safety lock function and simplifies the liquid filling process.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0008] In a first aspect, embodiments of this utility model provide a child-protective nasal spray device with a safety lock function, including a push button, a nasal spray pump, and a medicine bottle; the upper wall of the nasal spray pump housing is installed inside the push button housing via an elastic component and a locking component; the lower wall of the nasal spray pump housing is installed on the mouth of the medicine bottle via an anti-opening component;
[0009] The elastic component is an elastic protrusion on the inner wall of the push button housing. The locking component is a transverse track on the outer surface of the upper wall of the nasal spray pump housing. The transverse track has a locking point. When the elastic protrusion is located at the locking point, the nasal spray pump is locked. The anti-opening component includes a pawl on the lower wall of the nasal spray pump housing and a pawl on the mouth of the medicine bottle. The two pawls engage with each other.
[0010] As a further technical solution, the elastic protrusion is provided with three surfaces: the first surface is an arc surface, the second and third surfaces are planes, the angle between the first and second surfaces is 105-135°, and the angle between the second and third surfaces is 135-165°.
[0011] As a further technical solution, a rectangular groove is provided at the locking point, which enables the three surfaces of the elastic protrusion to be subjected to force, thereby playing a limiting role.
[0012] As a further technical solution, the elastic protrusion is made of an elastic material that deforms under certain pressure and can return to its original shape when no pressure is applied.
[0013] As a further technical solution, the push button housing and the nasal spray pump housing are fitted with a clearance, with a minimum clearance of 0.3-1.5mm and a maximum clearance of 2-6mm.
[0014] As a further technical solution, a longitudinal track is also provided on the outer surface of the upper wall of the nasal spray pump housing. When the elastic protrusion is located within the longitudinal track, the elastic protrusion is not subjected to force.
[0015] As a further technical solution, the number of pawls on the lower wall of the nasal spray pump housing is 18-36, and the angle of the pawls on the nasal spray pump housing is 80-100°.
[0016] As a further technical solution, the number of pawls on the mouth of the medicine bottle is 4-8, and the angle of the pawls is 50-70°.
[0017] As a further technical solution, the overlap distance between the pawl on the lower wall of the nasal spray pump housing and the pawl on the mouth of the medicine bottle is 0.2-0.8mm.
[0018] As a further technical solution, the lower wall of the nasal spray pump housing and the bottle opening are sealed by threads.
[0019] The beneficial effects of the above-described embodiments of this utility model are as follows:
[0020] (1) This utility model achieves a dual safety mechanism through the setting of elastic components, locking components and anti-opening components, namely, preventing the push button from being pressed down and preventing the medicine bottle from being opened. When the elastic component is locked into the locking position of the horizontal track, the push button cannot be pressed down, preventing children from accidentally spraying the medicine. The two pawls of the anti-opening component make it impossible for the medicine bottle to be turned counterclockwise, eliminating the risk of children accidentally opening the bottle and swallowing the medicine. In addition, it also avoids the hidden danger of aluminum shavings pollution caused by the traditional rolling process, and simplifies the medicine filling and sealing process.
[0021] (2) The elastic component of this utility model can move on the longitudinal and transverse tracks on the upper wall of the nasal spray pump housing. The longitudinal track is used for spraying the medicine and cleaning and maintenance, while the transverse track is used for locking to prevent children from opening it. The threads on the lower inner wall of the nasal spray pump housing engage with the threads on the bottle mouth to provide a seal. At the same time, the pawl on the housing engages with the pawl on the bottle mouth to prevent the bottle from being accidentally unscrewed. This device not only effectively prevents children from accidentally ingesting the medicine and improves the safety of use, but also avoids the safety hazards caused by aluminum shavings in the crimping sealing method, simplifies the medicine filling process, and reduces production costs.

[0033] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0034] Example 1
[0035] In a typical embodiment of this utility model, such as Figures 1 to 3 As shown, a child-protective nasal spray device with a safety lock function is provided, including a push button 1, a nasal spray pump 5, and a medicine bottle 4; the upper wall 2 of the nasal spray pump housing is installed inside the housing of the push button through an elastic component and a locking component; the lower wall 3 of the nasal spray pump housing is installed on the bottle opening 401 of the medicine bottle 4 through an anti-opening component;
[0036] The elastic component is an elastic protrusion 102 provided on the inner wall of the push button housing 101. The locking component is a transverse track 201 provided on the outer surface of the upper wall of the nasal spray pump housing. The transverse track 201 is provided with a locking point 202. When the elastic protrusion 102 is located at the locking point 202, the nasal spray pump is locked. The anti-opening component includes a pawl provided on the lower wall 3 of the nasal spray pump housing and a pawl on the mouth of the medicine bottle. The two pawls engage with each other.
[0037] The above structure implements a dual safety mechanism, namely preventing the push button from being pressed down and preventing the medicine bottle 4 from being opened. When the elastic component is engaged with the locking point 202 of the horizontal track 201, the push button cannot be pressed down, preventing children from accidentally spraying the medicine. The two pawls of the anti-opening component make it impossible for the medicine bottle 4 to be turned counterclockwise, eliminating the risk of children accidentally opening the bottle and swallowing the medicine. In addition, it avoids the hidden danger of aluminum shavings pollution caused by traditional crimping process, and simplifies the medicine filling and sealing process.
[0038] In this embodiment, the push button 1 includes a push button housing 101 and a nozzle. The push button housing 101 is connected to the nozzle. The outer wall of the medicine bottle 4 has threads and a pawl, with the threads above the pawl and the thread direction being clockwise. The nasal spray pump includes a pump head and a nasal spray pump housing. The upper outer wall of the nasal spray pump housing has a longitudinal track 203 and a transverse track 201. When the elastic protrusion 102 is located within the longitudinal track 203, the elastic protrusion 102 is not subjected to force. The lower inner wall of the nasal spray pump housing has threads and a pawl. The lower wall 3 of the nasal spray pump housing and the medicine bottle mouth are sealed by threads.
[0039] like Figure 5 As shown, the elastic protrusion 102 has three surfaces: the first surface 1021 is an arc surface, and the second surface 1022 and the third surface 1023 are flat surfaces. The angle between the first surface 1021 and the second surface 1022 is 105-135°, and the angle between the second surface 1022 and the third surface 1023 is 135-165°. Furthermore, a rectangular groove is provided at the locking point 202. This rectangular groove allows the three surfaces of the elastic protrusion 102 to bear force, thus providing a limiting function. Within this angle range, the elastic protrusion 102 is difficult to move clockwise at the locking point 202, while counterclockwise movement requires a large torque to move it to the intersection of the longitudinal track 203 and the transverse track, allowing for further longitudinal displacement to spray the liquid. The clever angle design and material selection of the elastic component enable a locking function at a specific location.
[0040] In this embodiment, the elastic protrusion 102 is made of an elastic material that deforms under pressure and returns to its original shape when no pressure is applied. Elastic materials include, but are not limited to, spring steel (65Mn, 55Si2Mn), stainless steel, copper alloys, titanium alloys, and metal-polymer composites (metal skeleton + rubber coating).
[0041] like Figure 4 As shown, the push button housing 101 and the nasal spray pump housing are fitted with a clearance, with a minimum clearance 6 of 0.3-1.5 mm and a maximum clearance 7 of 2-6 mm.
[0042] like Figure 6 As shown, the nasal spray pump housing pawl 301 engages with the bottle mouth pawl 402. During spiral sealing, the above structure rotates clockwise and moves downward until the bottle mouth is completely sealed. When rotating counterclockwise, the bottle mouth pawl 402 and the nasal spray pump housing pawl 301 engage with each other and cannot be opened.
[0043] like Figure 8As shown, the nasal spray pump housing has 18-36 pawls on its lower wall 3, with a pawl angle 302 of 80-110°. The medicine bottle 4 has 4-8 pawls on its neck, with a pawl angle 403 of 50-70°. This structure ensures that the bottle cannot move when rotated counterclockwise, thus preventing it from opening. Furthermore, when the pawls on the lower wall 3 of the nasal spray pump housing and the pawls on the neck of the medicine bottle 4 engage, the pawl overlap distance 8 is 0.2-0.8 mm. Figure 7 As shown, the bottle mouth pawl and the nasal spray pump housing pawl undergo slight deformation when rotated. The deformation distance is the overlap distance of 0.2-0.8mm. A suitable torque is used for spiral sealing.
[0044] The working principle of the child-protective nasal spray device provided in this embodiment is as follows:
[0045] The elastic protrusion 102 on the push button housing 101 can move within the longitudinal track 203 and the transverse track 201 on the upper wall 2 of the nasal spray pump housing. The longitudinal track 203 is the working track of the nasal spray pump. When the push button moves up and down, the elastic protrusion 102 is not under force, and the user can easily spray the medicine. The transverse track 201 is a locking track. When the push button and the elastic component are rotated clockwise from the reset position of the longitudinal track 203, the force on the elastic component gradually increases. When rotated to the locking position 202, the elastic protrusion 102 is under force on three sides, and the push button is locked to prevent children from opening it. The push button can be rotated counterclockwise from the locking position 202 back to the reset position of the longitudinal track 203 to dispense medicine again. The nasal spray pump housing and the bottle 4 are sealed by threads. During the spiral sealing, the screw rotates clockwise and moves downward until the bottle opening is completely sealed. When rotating counterclockwise, the pawls of the bottle opening and the pawls of the nasal spray pump housing engage with each other and cannot be opened. The anti-opening function is achieved by the pawls on the lower inner wall of the nasal spray pump housing cooperating with the pawls on the lower edge of the thread of the bottle opening.
[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
