Abstract
Description
Technical Field
[0001] This utility model relates to the field of disposable cotton swab technology, specifically to a disposable cotton swab that can be filled with fluid. Background Technology
[0002] Traditional disposable refillable fluid swabs typically consist of a swab filled with a liquid, with an opening at one end for dispensing the liquid and a sealed end. Each end is then wrapped with a cotton tip for wiping. To prevent leakage during storage, a barrier agent is often used at the open end to create a seal. A foldable section is located at the sealed end of the swab, within the coverage area of the cotton tip. During use, the foldable section is broken, allowing the liquid and barrier agent to flow out from the open end into the corresponding cotton tip. However, this traditional design has several drawbacks. First, the performance of the barrier agent often limits the shelf life of the liquid and the sealing effect, potentially leading to spoilage or leakage during storage. Second, because only the cotton tip at the open end can be moistened with liquid for wiping after the swab breaks, the cotton tip at the sealed end is discarded due to lack of contact with the liquid, resulting in resource waste. Therefore, developing a new type of disposable cotton swab that can be filled with fluid to overcome the limitations of traditional designs, improve sealing performance, ensure long-term preservation of the liquid, optimize usage, reduce waste, and enhance user experience is an urgent problem that needs to be solved.

[0024] It should be understood that, for clarity, the accompanying drawings are not drawn to scale, and the same or similar reference numerals indicate the same or similar parts or components. Furthermore, it should be understood that any embodiments described in this application and the technical features they include can be combined with each other.
[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0026] like Figure 1 and Figure 2 As shown, this is a disposable cotton swab that can be filled with fluid in its original state. It generally includes a swab body 1, a wiping section 3, and a foldable section 4. The swab body 1 serves as the main structure of the swab, and both ends of the swab body 1 have sealing sections 2. The swab body 1 and the two sealing sections 2 together form a filling cavity 1a for containing fluid. The sealing sections 2 can be provided with sealing caps or heat-sealed to ensure the airtightness of the filling cavity 1a. The interior of the filling cavity 1a can be filled with various fluid materials, such as disinfectants, medicines, saline solutions, lubricants, or cosmetics. Generally, the filling cavity 1a is filled with fluid.
[0027] The rod 1 has a length of 5cm-20cm and a diameter of 1.5mm±0.5mm. The rod 1 is a cylindrical structure, but can be adjusted to other shapes such as ellipse, polygon, or square as needed. The filling cavity 1a is a cylindrical cavity coaxial with the rod 1. The shape of the filling cavity 1a can be the same as or different from that of the rod 1. The rod 1 can be made of plastic, wood, etc., but a transparent plastic is preferred, allowing observation of the fluid within the filling cavity 1a from the outside.
[0028] In an embodiment not shown, the diameter of the middle part of the rod 1 is smaller than the diameter of the two sides of the rod 1, that is, the diameter of the rod 1 gradually decreases from its two ends to the middle, which makes the rod 1 easier to break.
[0029] Continue to refer to Figure 1 and Figure 2 The wiping part 3 is sleeved in the middle of the rod body 1. The wiping part 3 is flexible. In this embodiment, the wiping part 3 is a cotton head. The cotton head is tightly wrapped around the outer wall of the middle part of the rod body 1 by a wrapping process to form a spindle-shaped structure, so that the thickness of the middle part of the cotton head is greater than the thickness of the two sides. The thickening of the middle part of the cotton head can prevent the cotton head from deforming after the rod body 1 breaks, thus affecting the fluid adsorption capacity. At the same time, it can release the fluid evenly during use, avoiding the fluid from overflowing outside the cotton head or excessive local fluid. The material of the cotton head is degreased cotton.
[0030] Continue to refer to Figure 3The easily breakable part 4 is circumferentially disposed in the middle of the rod body 1 and located in the coverage area of the wiping part 3. The easily breakable part 4 includes multiple grooves 401 arranged at certain intervals along the circumferential wall of the rod body 1. The multiple grooves 401 together form an easily breakable line. The grooves 401 are strip-shaped, V-shaped, square, annular, or wavy, thereby forming a fracture path on the outer wall of the middle part of the rod body 1, ensuring accurate fracture under external force and a smooth edge of the liquid outlet 103. For example, the groove 401 is strip-shaped, with the length direction of the strip-shaped groove parallel to the length direction of the rod body 1, and arranged sequentially on the circumferential wall of the rod body 1, thereby forming an easily breakable line. Another example is that the groove 401 is annular, with multiple grooves 401 closely arranged along the circumferential wall of the rod body 1, that is, one groove is closely attached to the adjacent groove and interconnected, thereby forming an annular easily breakable line. This annular groove is close to the outer wall of the filling cavity 1a. The flexible section 4 is used to break the rod 1 by external force to form a liquid outlet 103, allowing the fluid in the filling cavity 1a to be discharged through the liquid outlet 103 and permeate into the wiping section 3. There are two liquid outlets 103. The flexible section 4 is located in the middle of the wiping section 3 to ensure that the fluid flowing out after the rod 1 is broken by the flexible section 4 can be evenly distributed in the wiping section 3.
[0031] The easily breakable part 4 divides the rod 1 into a first rod 101 and a second rod 102. After breaking, it forms two independent rod segments 1, which are connected by a wiping part 3 at the end forming the liquid outlet 103. The sealing part 2 is located at one end of the first rod 101 and the second rod 102 respectively, and the liquid outlet 103 is formed at the other end of the first rod 101 and the second rod 102 respectively after breaking. The length of the first rod 101 and the length of the second rod 102 may be equal or unequal. That is, the length of the first rod 101 can be equal to the length of the second rod 102, or the length of the first rod 101 can be greater than the length of the second rod 102, or the length of the first rod 101 can be less than the length of the second rod 102. The length of the first rod 101 is 2.5cm-10cm, and the length of the second rod 102 is 2.5cm-10cm.
[0032] like Figure 1 and Figure 4 As shown, the outer surface of the wiping part 3 is provided with a breakage indicator line 301 corresponding to the easily broken part 4, so that the user can accurately locate the easily broken part 4 and apply external force. The easily broken part 4 is located in the middle of the rod body 1, and the breakage indicator line 301 is located in the middle of the wiping part 3.
[0033] Refer to Figure 4 and Figure 5The illustration shows a disposable cotton swab used for wiping after the swab body 1 is broken. In its original state, the first swab body 101 and the second swab body 102 are arranged in series and parallel to each other. After the swab body 1 is broken, although two independent swab bodies are formed, the first swab body 101 and the second swab body 102 are connected by the wiping part 3. At this time, the first swab body 101 can rotate around the broken position and be arranged side by side with the second swab body 102, so that the liquid outlet 103 of the first swab body 101 is roughly flush with the liquid outlet 103 of the second swab body 102. At the same time, the wiping part 3 undergoes elastic deformation under the action of torsional force, and the wiping part 3 can completely cover the liquid outlet 103 of the first swab body 101 and the second swab body 102 to prevent fluid from overflowing. At the same time, the deformation of the cotton head increases the contact area and improves the cleaning or wiping efficiency.
[0034] In an embodiment not shown, an anti-slip ring is also provided on the outer wall of the rod 1, that is, an anti-slip ring is provided on the outer wall of both the first rod 101 and the second rod 102. The anti-slip ring is a raised annular pattern, which is located between the sealing part 2 and the easily foldable part 4. The anti-slip ring is used to enhance the user's grip stability during use and prevent the hand from slipping.
[0035] In an embodiment not shown, the first rod 101 and the second rod 102 each have a first fitting portion and a second fitting portion on the sidewall of the end with the sealing portion 2, respectively. When the rod 1 breaks, the first rod 101 can rotate around the broken position to be arranged side by side with the second rod 102. At this time, the first fitting portion of the first rod 101 and the second fitting portion of the second rod 102 correspond to each other and fit together, thereby preventing the first rod 101 from deviating from the second rod 102 due to the rebound force of the wiping portion 3, which would affect the use of the wiping portion 3. The fitting method can be adhesive, snap-fit, etc.
[0036] Based on the above-described disposable cotton swab that can be filled with fluid, during use, observe the break indicator line 301 on the cotton swab to find the position corresponding to the easily broken part 4. Hold both ends of the swab body 1 and apply appropriate external force at the easily broken part 4 to break the swab body 1 along the easily broken line, forming two independent swab parts, namely the first swab body 101 and the second swab body 102. Rotate the first swab body 101 around the break point so that it is arranged side by side with the second swab body 102. The fluid in the filling cavity 1a will be discharged through the two liquid outlets 103 and penetrate into the wiping part 3. Hold one end of the swab body 1 and gently press the wiping part 3 onto the area that needs to be cleaned or coated.
[0037] In summary, this invention relates to a disposable fluid-fillable cotton swab, comprising a stick body, a wiping section, and a breakable section. The stick body has sealing sections at both ends, and the breakable section is located in the middle of the stick body. The wiping section is located in the middle of the stick body and covers the breakable section. In use, the user can break the stick body at the breakable section in the middle, thus forming a liquid outlet, allowing the fluid to drain from the outlet and permeate into the wiping section for wiping. This design allows the fluid to be sealed and preserved within the filling cavity without relying on a barrier agent, thus providing good sealing performance and ensuring the liquid can be stored for a long time without deterioration. Furthermore, it ensures that the wiping section is fully utilized, effectively avoiding resource waste.
