[0029] The inner core 3 is sleeved with an intermediate body 2, the inner wall of the intermediate body 2 is attached to the inner core 3 to ensure that the ointment is taken as needed without residue. The tail of the intermediate body 2 is positioned and assembled with the inner core 3 by a first connecting piece. A smooth arc surface is arranged on the outer wall of the head of the intermediate body 2 for directly applying the ointment to avoid contacting the ointment with the hand. An ointment outlet 9 is arranged on the head of the intermediate body 2, which corresponds to the ointment outlet 7.

[0030] The intermediate body 2 is in transmission cooperation with the control mechanism to open or close the ointment outlet 7.

[0031] The head of the intermediate body 2 is provided with a conical inner wall, the head of the conical inner wall is smoothly connected to the inner wall of the ointment outlet 9, and the inner diameter of the conical inner wall gradually increases away from the ointment outlet 9. The conical inner wall is in abutting transmission cooperation with the plurality of sealing columns 6 to gather the plurality of sealing columns 6 in the ointment outlet 9 to block the ointment outlet 7 and the ointment outlet 9.

[0032] The first connecting member comprises a ring-shaped clamping groove 12, an inner cavity circular platform 5, a limiting groove 4 and a transmission block 13. The ring-shaped clamping groove 12 is formed on the outer wall of the inner core 3 along the circumferential direction of the tube opening of the ointment tube, and the inner cavity circular platform 5 is fixed to the inside of the intermediate body 2. The inner cavity circular platform 5 is located in the ring-shaped clamping groove 12 and is in both rotational and sliding cooperation with the inner core 3. Therefore, the intermediate body 2 can slide up and down along the axial direction of the tube opening of the ointment tube and rotate along the circumferential direction of the tube opening of the ointment tube.

[0033] The limiting groove 4 is formed on the inner wall of the intermediate body 2, and the transmission block 13 is fixedly arranged on the outer wall of the inner core 3. The transmission block 13 is slidingly arranged in the limiting groove 4, and the intermediate body 2 and the transmission block 13 are in abutting transmission cooperation.

[0034] The limiting groove 4 is in the shape of L or Z. If the limiting groove 4 is in the shape of L, one part of the limiting groove 4 is arranged along the axial direction of the tube opening of the ointment tube and is used for the sliding of the intermediate body 2 along the axial direction of the tube opening of the ointment tube, and the other part is arranged along the circumferential direction of the tube opening of the ointment tube and is used for the rotation of the intermediate body 2 along the circumferential direction of the tube opening of the ointment tube. The two parts are connected to each other so that the transmission block 13 can slide and switch between the two parts.

[0035] If the limiting groove 4 is in the shape of Z, it can be adapted to a large-diameter ointment tube, thereby increasing the rotation step to form a child lock function. Two parts of the Z-shaped limiting groove 4 are arranged along the circumferential direction of the tube opening of the ointment tube and are used for the rotation of the intermediate body 2 along the circumferential direction of the tube opening of the ointment tube, and the remaining part is arranged along the axial direction of the tube opening of the ointment tube and is used for the sliding of the intermediate body 2 along the axial direction of the tube opening of the ointment tube. The part arranged along the axial direction of the tube opening of the ointment tube is located between the two parts arranged along the circumferential direction of the tube opening of the ointment tube and is connected to the two parts.

[0036] A rotation indication line of the intermediate body 2 is arranged on the outer wall of the intermediate body 2 along the circumferential direction of the tube opening of the ointment tube. Two ends of the indication line are respectively provided with on and off indication words 11. The indication words 11 correspond to and match the limiting groove 4. The on indication word 11 indicates that the intermediate body 2 is rotated counterclockwise to abut against the transmission block 13. The off indication word 11 indicates that the intermediate body 2 is rotated clockwise to abut against the transmission block 13.

[0037] The cover body 1 is sleeved on the intermediate body 2. The bottom of the cover body 1 is detachably assembled with the intermediate body 2 through the second connecting member, so that the cover body 1 can be conveniently disassembled and assembled. The top of the cover body 1 is provided with a needle, which is convenient for piercing the sealing film at the tube opening of the ointment tube during the first use.

[0038] The second connecting piece comprises a limiting ring groove 14 and a limiting sliding block 10. The limiting ring groove 14 is formed on the inner wall of the cover 1 along the circumference of the tube opening of the ointment tube. A notch is formed on the inner wall of the cover 1 along the direction close to the tube opening of the ointment tube, and the notch is communicated with the limiting ring groove 14 and passes through the cover 1. The limiting sliding block 10 is fixed on the middle body 2 and located in the limiting ring groove 14. The limiting sliding block 10 is in sliding cooperation with the limiting ring groove 14 and matches with the notch and can slide out of the notch.

[0039] Working principle: when used for the first time, the user needs to unscrew the cover 1. During the unscrewing process, the cover 1 is rotated, and when the limiting sliding block 10 slides to correspond to the notch, the cover 1 can be pulled off. The correspondence between the limiting sliding block 10 and the notch can be determined by setting a mark corresponding to the limiting sliding block 10 on the cover 1 and a mark corresponding to the limiting sliding block 10 on the middle body 2.

[0040] Then the sealing film at the tube opening of the ointment tube is pierced by the lancet.

[0041] Then the middle body 2 is screwed, and the middle body 2 drives the inner core 3 to be threadedly connected with the tube opening of the ointment tube through the transmission block 13.

[0042] When the ointment needs to be applied, the middle body 2 is lifted upward along the axial direction of the tube opening of the ointment tube. When the transmission block 13 slides from the part of the limiting groove 4 arranged along the axial direction of the tube opening of the ointment tube to the part of the limiting groove 4 arranged along the circumferential direction of the tube opening of the ointment tube, the middle body 2 stops sliding upward. At this time, the middle body 2 is rotated counterclockwise, so that the transmission block 13 is clamped into the part of the limiting groove 4 arranged along the circumferential direction of the tube opening of the ointment tube.

[0043] During the above process, the sealing columns 6 are separated from the ointment outlet 9 on the middle body 2. Then, the sealing columns 6 are opened to the ointment outlet 7 under the action of their own elasticity.

[0044] Then the ointment is squeezed out for application. After the application is completed, the middle body 2 is rotated clockwise. Then the middle body 2 is pressed downward, and the sealing columns 6 are gathered into the ointment outlet 9 again, so as to block the ointment outlet 7.

[0045] Finally, it should be pointed out that the above description is only a preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
