Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a quick-release cap for vials. Background Technology

[0002] Currently, vials are widely used containers for storing pharmaceuticals and biological products, and their cap design directly affects the sealing, ease of use, and safety of the medicine. Traditional vial caps are mostly made of aluminum and are opened primarily by rotating or pulling.

[0003] Traditional vial caps are typically made of aluminum alloy, offering excellent sealing and corrosion resistance. The cap usually has a sealing gasket inside to ensure the safety and efficacy of the medication inside. The cap fits tightly onto the vial and is opened by rotating it. Users need to rotate the cap clockwise or counterclockwise to separate it from the vial opening, making it easy to access the medication.

[0004] In terms of traditional related technologies, in order to ensure a sealing effect, the cap of the vial needs to be tightly fastened to the vial. Opening the cap requires considerable force or the use of a special cap-opening tool. When the medication in the vial needs to be used urgently, if no cap-opening tool is carried, it will take a lot of time to open the cap, which is quite inconvenient. Utility Model Content

[0005] To improve the ease of opening the cap, this application provides a quick-release cap for vials.

[0006] This application provides a quick-release cap for vials, employing the following technical solution:

[0007] A quick-release cap for a vial includes a cap and a sealing gasket. The cap includes an outer cap and an inner cap. The outer cap is used to connect to the mouth of the vial. The sealing gasket is disposed inside the outer cap. The outer cap pushes the sealing gasket to seal the mouth of the vial. The inner cap is located inside the outer cap and fits against the outer cap along its circumferential side. The upper end of the outer cap has an opening, which is sealed by the inner cap. A pull plate is fixed to the upper end of the outer cap. In its natural state, the pull plate is located inside the opening. Two easy-tear openings are opened on the side of the outer cap. The two easy-tear openings are located on both sides of the pull plate and extend along the length of the pull plate.

[0008] By adopting the above technical solution, during installation, the outer cover connects to the mouth of the vial, and pushes the sealing gasket to seal the mouth of the vial. The inner cover seals the opening on the outer cover. When opening the cover, since the inner cover and the outer cover are in close contact, by pulling the pull plate at the opening, the pull plate moves along the easy-tear opening, the pull plate separates from the outer cover, and the outer cover forms a notch, making it easy to open the outer cover and improving the convenience of opening the cover.

[0009] Optionally, the upper surface of the outer cover has three easy-tear grooves along the circumference, one of which is located on the side of the outer cover away from the easy-tear opening, and the other two are located on the sides away from the easy-tear opening.

[0010] By adopting the above technical solution, pulling the pull plate moves it along the easy-tear groove, positioning it on the side of the outer cap, creating a notch in the outer cap. Pulling the pull plate away from the vial allows the outer cap to bend more smoothly along the easy-tear groove, thus opening the outer cap and improving the ease of opening.

[0011] Optionally, one of the tear-off openings is a break groove that extends to the side of the outer cover away from the opening. A reinforcing ring is provided circumferentially on the outer side of the outer cover. The reinforcing ring is fixed between the outer cover and the pull plate, and the two ends of the reinforcing ring are located on both sides of the break groove.

[0012] By adopting the above technical solution, the pull plate is pulled to move and flip along the fracture groove. When the pull plate is pulled, it cuts the outer cover through the fracture groove, forming a fracture in the outer cover. The reinforcing ring is used to improve the connection strength between the pull plate and the outer cover. After the outer cover is broken, the pull plate drives the outer cover to separate from the vial, improving the convenience of opening the cap.

[0013] Optionally, the inner cover is fixedly equipped with a needle, which is located inside the inner cover and is arranged along the axial direction of the inner cover. The inner cover is slidably connected to the outer cover along the axial direction of the outer cover. When the outer cover is connected to the vial, the needle and the sealing gasket do not contact each other.

[0014] By adopting the above technical solution, when opening the cover, pressing the inner cover causes it to slide along the axis of the outer cover, which in turn drives the needle to penetrate the sealing gasket, thus improving the ease of opening the cover.

[0015] Optionally, a positioning ring is fixed on the inner side of the outer cover, and the positioning ring is located between the inner cover and the sealing gasket.

[0016] By adopting the above technical solution, when opening the bottle, pressing the inner cap causes it to contact the positioning ring. When opening the outer cap, the positioning ring moves the inner cap away from the vial, thus improving the ease of opening the bottle.

[0017] Optionally, the sides of the outer cover are provided with several anti-slip textures.

[0018] By adopting the above technical solution, the anti-slip texture can increase the friction between the bottle cap and the hand during the opening process, thus improving the stability of opening the cap.

[0019] Optionally, an annular protrusion is fixed at the lower end of the outer cover, the annular protrusion is located on the inner side of the outer cover, and the sealing gasket is located between the annular protrusion and the positioning ring.

[0020] By adopting the above technical solution, the annular protrusion secures the outer cap to the mouth of the vial, thereby improving the connection stability between the outer cap and the vial.

[0021] Optionally, an extension plate is fixed to the side of the outer cover away from the tear opening, and the extension plate is horizontally positioned.

[0022] By adopting the above technical solution, when opening the cap, the pull plate is pulled open through the easy-tear opening, and the extension plate is moved away from the vial to open the outer cap, thus improving the convenience of opening the cap.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The easy-tear opening allows the pull plate to move along the easy-tear opening during the opening process, creating a notch in the outer cap. The easy-tear groove makes the outer cap separate from the vial more smoothly, improving the convenience of opening the cap.

[0025] 2. Press the inner cap to make it contact the positioning ring. When the outer cap is opened, the positioning ring moves the inner cap away from the vial, thus opening the cap.

[0026] 3. When opening the cap, pull the lever to separate the lever from the outer cap along the tear strip. Move the extension plate away from the vial to open the outer cap, thus improving the ease of opening the cap. Attached Figure Description

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.

[0033] This application discloses a quick-release bottle cap for vials.

[0034] Example 1

[0035] Reference Figure 1 A quick-release vial cap includes a cap 1 and a sealing gasket 2. The outer cap 11 connects to the vial opening, and the sealing gasket 2 is located inside the cap 1 to seal the vial opening. The cap 1 includes an outer cap 11 and an inner cap 12. The inner cap 12 is located inside the outer cap 11, and its circumferential side edge fits against the outer cap 11. The upper end of the outer cap 11 has an opening 13, which the inner cap 12 seals, reducing the probability of contamination of the sealing gasket 2.

[0036] Reference Figure 1 A pull plate 112 is fixedly provided at the upper end of the outer cover 11. In its natural state, the pull plate 112 is located inside the opening 13. Two easy-tear openings 113 are opened on the side of the outer cover 11. The two easy-tear openings 113 are located on both sides of the pull plate 112 and extend along the length of the pull plate 112. Pulling the pull plate 112 causes it to move along the break groove 118, forming a notch in the outer cover 11. Three easy-tear grooves 111 are provided circumferentially on the upper surface of the outer cover 11. One easy-tear groove 111 is located on the side of the outer cover 11 away from the easy-tear opening 113, and the other two easy-tear grooves 111 are located on both sides away from the easy-tear opening 113. Pulling the pull plate 112 moves away from the vial. The easy-tear grooves 111 allow the outer cover 11 to bend more smoothly along the easy-tear grooves 111, thereby opening the outer cover 11.

[0037] Example 2

[0038] Reference Figure 2 and Figure 3 The difference between this embodiment and Embodiment 1 is that an annular protrusion 117 is fixedly provided on the inner side of the outer cover 11. The annular protrusion 117 can lock the outer cover 11 and the vial, reducing the probability of the vial cap 1 falling off and improving the overall stability. Several anti-slip textures 115 are provided on the side of the outer cover 11. The anti-slip textures 115 are used to increase the friction between the vial cap 1 and the hand, reducing the probability of the vial slipping out of the hand. The inner side of the outer cover 11 is fixed with a positioning ring 116, which is located between the inner cover 12 and the sealing gasket 2. The inner cover 12 is fixed with a needle 121, which is located inside the inner cover 12 and is arranged along the axial direction of the inner cover 12. The inner cover 12 is slidably connected to the outer cover 11 along the axial direction of the outer cover 11. When the outer cover 11 is connected to the vial, the needle 121 and the sealing gasket 2 do not contact each other. By pressing the inner cover 12, the inner cover 12 slides along the axial direction of the outer cover 11, and the inner cover 12 contacts the positioning ring 116, which drives the needle 121 to penetrate the sealing gasket 2, thereby opening the sealing gasket 2.

[0039] Reference Figure 2 and Figure 3One of the tear-off openings 113 is a break groove 118, which extends to the side of the outer cover 11 away from the opening 13. A reinforcing ring 114 is provided circumferentially on the outer side of the outer cover 11. The reinforcing ring 114 is fixed between the outer cover 11 and the pull plate 112, and the two ends of the reinforcing ring 114 are located on both sides of the break groove 118. Pulling the pull plate 112 causes it to move and flip along the break groove 118, and then drives the pull plate 112 to move away from the vial to separate the outer cover 11 from the vial. Since the inner cover 12 is in contact with the positioning ring 116, opening the outer cover 11 also causes the inner cover 12 to separate from the vial, thereby opening the bottle cap 1.

[0040] Example 3

[0041] Reference Figure 4 The difference between this embodiment and embodiment 1 is that an extension plate 119 is fixed on the side of the outer cover 11 away from the easy-tear opening 113. The extension plate 119 is horizontally set. Pulling the pull plate 112 causes it to move along the easy-tear opening 113, and the pull plate 112 separates from the outer cover 11. The outer cover 11 forms a notch at the easy-tear opening 113. By oscillating the extension plate 119, the extension plate 119 is moved away from the vial, thereby separating the outer cover 11 from the vial.

[0042] The implementation principle of the quick-release bottle cap of the present application embodiment is as follows: Pull the pull plate 112 to move the pull plate 112 along the easy-tear opening 113, forming a notch in the outer cap 11. Pull the pull plate 112 to move away from the bottle, and the easy-tear groove 111 allows the outer cap 11 to bend along the easy-tear groove 111, so that the outer cap 11 can be opened more smoothly. Then remove the inner cap 12 to complete the entire process of opening the bottle cap 1.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
