Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and in particular to a pull-out sanitary napkin. Background Technology

[0002] With the increasing awareness of women's health care and the development of intelligent portable personal care products, there is a need for dust-free storage and convenient access to individually packaged sanitary napkins in scenarios such as outdoor travel, sports and fitness, and daily commuting. This is where pull-out sanitary napkins come in handy.

[0003] In actual use, similar pull-out sanitary napkins still have many drawbacks. For example, traditional pull-out sanitary napkins with ordinary open pockets or simple flip-top boxes are prone to loosening due to vibration and squeezing during carrying, allowing dust, bacteria and other contaminants to enter. At the same time, the traditional pull-out sanitary napkin is cumbersome and unhygienic to use. Therefore, it is necessary to design a pull-out sanitary napkin. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a pull-out sanitary napkin.

[0005] This utility model is achieved using the following technical solution: a pull-out sanitary napkin, comprising a storage component, the storage component including a storage box, the storage box having a dispensing slot inside, and further comprising:

[0006] The protective component includes a protective cover fixedly connected to the outer surface of the storage box. The protective cover has a movable groove inside, and a fixed seat is movably installed inside the movable groove through a spring damper. The outer surface of the fixed seat is provided with a first hook.

[0007] A sealing assembly, comprising a sealing cover rotatably connected inside a protective cover, wherein a second hook is fixedly connected to the outer surface of the sealing cover by a limiting seat, and the second hook matches a first hook.

[0008] As a further improvement to the above solution, guide rods are fixedly connected to both sides inside the movable groove, and a spring damper is fixedly connected to the top of the inner wall of the movable groove.

[0009] Through the above technical solution, guide rods are fixedly connected to both sides inside the movable groove. This design provides a clear linear motion track for the fixed seat, effectively constrains its lifting path, avoids tilting or shaking caused by uneven force, and significantly improves the stability and durability of the transmission system. At the same time, the presence of guide rods also reduces frictional loss between moving parts, making the pressing operation smoother and more fluid.

[0010] As a further improvement to the above solution, a connecting rod is fixedly connected to the bottom of the spring damper, and the connecting rod is slidably installed inside the movable groove.

[0011] Through the above technical solution, this rigid connection method not only enhances the response speed of the reset action, but also precisely controls the movement stroke of the fixed seat, preventing structural impact caused by excessive displacement.

[0012] As a further improvement to the above solution, a movable block is fixedly connected to the outer surface of the connecting rod, and the movable block is slidably installed on the outer surface of the guide rod.

[0013] As a further improvement to the above solution, a fixed seat is fixedly connected to the bottom of the connecting rod, and the fixed seat matches the movable groove.

[0014] Through the above technical solution, this rigid coupling not only improves the assembly accuracy, but also ensures the efficiency of torque transmission, ensuring that the small force applied by the user to the pressing plate can be converted into a reliable unlocking action.

[0015] As a further improvement to the above solution, a first hook is fixedly connected to one side of the outer surface of the fixing base, and a pressing plate is fixedly connected to the side of the outer surface of the fixing base away from the first hook.

[0016] Through the above technical solution, the first hook and the second hook are precisely engaged to form a safe and reliable locking mechanism. The synergistic effect of the two not only simplifies the operation process but also enhances the structural compactness.

[0017] As a further improvement to the above solution, a limiting seat is fixedly connected to the outer surface of the sealing cover, and a second hook is fixedly connected to the outer surface of the limiting seat.

[0018] The above technical solution ensures that the sealing cap can only open and close within a preset angle range through mechanical limiting, which not only prevents the risk of sanitary napkins falling out due to excessive opening, but also provides double insurance through the double hook interlocking mechanism, eliminating the problem of accidental unlocking caused by vibration during transportation.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model utilizes a transmission structure composed of a pressing plate, connecting rod, fixed base, and guide rod to cause the first and second latches to separate, thereby enabling the quick release of the seal lock with a single-handed press. This allows users to flip open the sealed cover without complicated operations, directly exposing the discharge slot inside the storage box. The limiting sliding of the moving block on the guide rod ensures the linear stability of the fixed base's movement and avoids jamming caused by offset, significantly improving retrieval efficiency. It also conforms to ergonomic principles, lowers the barrier to entry, and is especially suitable for quick one-handed operation in emergency situations.

[0021] This invention utilizes the combined effect of the elastic potential energy release of the spring damper and the gravity of the fixed base to drive the fixed base to smoothly rise back to its initial position along the guide rod. This causes the first hook to re-engage precisely with the second hook, and simultaneously, the limiting seat pushes the movement of the second hook, further assisting the fixed base to slide completely into the depth of the movable groove. This dual reset mechanism not only ensures the tight closure of the sealing cover and protective components, but also utilizes the buffering characteristics of the spring damper to reduce mechanical impact noise and extend the life of the components. The resulting multi-layered sealed structure effectively prevents external dust, moisture, and other contaminants from entering the storage box, maintaining the cleanliness of the sanitary napkins and meeting the stringent hygiene requirements for carrying them around, while also ensuring the durability of the device.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 This embodiment of a pull-out sanitary napkin includes a storage component 1, which includes a storage box 101. The storage box 101 has a dispensing slot 102 inside, and also includes:

[0032] Protective component 2 includes a protective cover 201 fixedly connected to the outer surface of storage box 101. The protective cover 201 has a movable groove 202 inside. A fixed seat 207 is movably installed inside the movable groove 202 through a spring damper 204. A first hook 208 is provided on the outer surface of the fixed seat 207.

[0033] The sealing assembly 3 includes a sealing cover 301 rotatably connected inside the protective cover 201. The outer surface of the sealing cover 301 is fixedly connected to a second hook 303 via a limiting seat 302. The second hook 303 matches the first hook 208.

[0034] Guide rods 203 are fixedly connected to both sides inside the movable groove 202, and spring dampers 204 are fixedly connected to the top of the inner wall of the movable groove 202.

[0035] A connecting rod 205 is fixedly connected to the bottom of the spring damper 204, and the connecting rod 205 is slidably installed inside the movable groove 202.

[0036] A movable block 206 is fixedly connected to the outer surface of the connecting rod 205, and the movable block 206 is slidably installed on the outer surface of the guide rod 203.

[0037] The bottom of the connecting rod 205 is fixedly connected to a fixed seat 207, which matches the movable groove 202.

[0038] A first hook 208 is fixedly connected to one side of the outer surface of the fixing base 207, and a pressing plate 209 is fixedly connected to the side of the outer surface of the fixing base 207 away from the first hook 208.

[0039] After the pressing plate 209 is released, under the combined action of the elastic force of the spring damper 204 and the weight of the fixed seat 207 itself, the fixed seat 207 is automatically reset. The fixed seat 207 smoothly rises back to the initial position along the guide rod 203, causing the first hook 208 to re-engage precisely with the second hook 303.

[0040] The outer surface of the sealing cover 301 is fixedly connected to the limiting seat 302, and the outer surface of the limiting seat 302 is fixedly connected to the second hook 303.

[0041] As the sealing cover 301 is snapped back into the protective cover 201, the limiting seat 302 pushes the second hook 303 to move synchronously, further assisting the fixing seat 207 to slide completely into the depth of the movable groove 202. This dual reset mechanism not only ensures the tight closure of the sealing cover 301 and the protective component 2, but also reduces mechanical impact noise through the buffering effect of the spring damper 204, extends the service life of the component, and the final closed structure effectively blocks external dust.

[0042] The implementation principle of a pull-out sanitary napkin in this embodiment is as follows: When a user needs to take out a sanitary napkin, he first presses down on the pressing plate 209 located outside the protective cover 201. The force is transmitted to the fixed seat 207 through the connecting rod 205, causing it to slide down along the guide rod 203 in the movable groove 202. During this process, the first hook 208 on the fixed seat 207 disengages from the engagement state with the second hook 303 on the sealing cover 301, releasing the lock on the sealing component 3. At this time, the user can flip open the sealing cover 301, so that the discharge groove 102 inside the storage box 101 is fully exposed, thereby smoothly pulling out the sanitary napkin stacked therein. This design achieves quick unlocking through a simple pressing action, which is convenient to operate and conforms to the ergonomic logic of one-handed use. At the same time, the cooperation between the moving block 206 and the guide rod 203 ensures the linearity and stability of the movement of the fixed seat 207, avoiding jamming caused by deviation.

[0043] After releasing the pressing plate 209, under the combined action of the elastic force of the spring damper 204 and the weight of the fixing seat 207 itself, the fixing seat 207 is automatically reset. The fixing seat 207 smoothly rises back to the initial position along the guide rod 203, causing the first hook 208 to re-engage precisely with the second hook 303. At the same time, as the sealing cover 301 is snapped back into the protective cover 201, the limiting seat 302 pushes the second hook 303 to move synchronously, further assisting the fixing seat 207 to slide completely into the depth of the movable groove 202. This dual reset mechanism not only ensures the tight closure of the sealing cover 301 and the protective component 2, but also reduces mechanical impact noise through the buffering effect of the spring damper 204, extending the life of the components. The resulting closed structure effectively blocks external dust, moisture and other pollutants from entering the storage box 101, ensuring that the sanitary napkins inside are always kept clean, which is especially suitable for scenarios with high requirements for hygiene when carried on the person.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
