Technical Field

[0001] This utility model relates to the field of ointment sealing cap technology, and in particular to an ointment sealing cap. Background Technology

[0002] Existing ointment sealing caps are generally threaded onto the extrusion port of the ointment receiving shell to prevent ointment leakage. When the ointment needs to be used, the sealing cap must first be unscrewed and set aside, then the ointment receiving shell must be squeezed to force the ointment out through the extrusion port. However, with this type of sealing cap, the cap must be completely detached from the ointment receiving shell before use, making it easy to lose or soil the sealing cap. Utility Model Content

The outer shell annular flange is located above the outer shell limiting step. An upward-opening inner shell limiting step is provided between the outer circumferential surface of the top end of the first inner shell cylinder and the outer circumferential surface of the bottom end of the second inner shell cylinder. The inner shell limiting step is movably disposed below the outer shell limiting step. The inner shell limiting step and the outer shell limiting step can form a limiting fit in the vertical direction.

[0008] Furthermore, an outer circumferential step with an upward opening is provided between the outer circumferential surface of the top end of the first outer shell cylinder and the outer circumferential surface of the bottom end of the second outer shell cylinder, and the outer shell limiting step and the outer shell step are in an inner-outer position correspondence; the outer circumferential surface of the first outer shell cylinder is provided with a plurality of vertically extending anti-slip posts, and the plurality of anti-slip posts are distributed sequentially along the circumferential direction of the first outer shell cylinder.

[0009] Furthermore, the inner circumferential surface at the bottom end of the first outer shell cylinder is provided with an inner shell internal thread, and the outer circumferential surface at the bottom end of the first inner shell cylinder is provided with an inner shell external thread, wherein the outer shell internal thread and the inner shell external thread form a threaded connection.

[0010] Furthermore, the inner diameter of the top end of the first inner shell cylinder is the same as the inner diameter of the second inner shell cylinder, so that the interior of the top end of the first inner shell cylinder and the interior of the second inner shell cylinder form a circular channel.

[0014] In summary, the technical solution of this utility model has the following beneficial effects: The structure of this utility model is reasonably designed. By setting an outer shell and an inner shell, the inner shell is located inside the outer shell. The outer shell and the inner shell are coaxially arranged, threadedly connected to the outer shell, and can move up and down inside the outer shell. The outer shell includes a first outer shell cylinder, a second outer shell cylinder, and a discharge pipe connected sequentially from bottom to top. The inner diameter of the first outer shell cylinder is larger than the inner diameter of the second outer shell cylinder, and the inner diameter of the second outer shell cylinder is larger than the inner diameter of the discharge pipe. The inner shell includes a first inner shell cylinder, a second inner shell cylinder, and a plug rod connected sequentially from bottom to top. The outer diameter of the first inner shell cylinder is larger than the outer diameter of the second inner shell cylinder, and the outer diameter of the second inner shell cylinder is larger than the outer diameter of the plug rod. The first inner shell cylinder is movably disposed inside the first outer shell cylinder, and the second inner shell cylinder is movably disposed inside the first outer shell cylinder. The inner and outer shells of the grease sealing cap are positioned inside the first and second outer shell cylinders, with a plug rod movably disposed inside the second outer shell cylinder and the discharge pipe. A discharge hole is provided between the top edge of the second inner shell cylinder and the bottom edge of the plug rod. In practical use, the bottom end of the inner shell of the grease sealing cap can be connected and fixed to the extrusion port of the grease receiving shell. At this time, because the plug rod blocks the discharge pipe upwards, leakage of the grease from the grease receiving shell is prevented. When the grease needs to be used, because the inner and outer shells are threadedly connected, the outer shell can be loosened upwards without completely detaching from the inner shell. At this time, the plug rod no longer blocks the discharge pipe, and the grease receiving shell is then squeezed, causing the grease inside the grease receiving shell to be extruded outwards sequentially through the first inner shell cylinder, the second inner shell cylinder, the discharge hole, the second outer shell cylinder, and the discharge pipe. From the above analysis, it can be seen that the inner and outer shells of the grease sealing cap of this invention do not need to be completely detached to achieve grease extrusion, avoiding loss or soiling of the grease sealing cap.

[0026] See Figures 1 to 8This embodiment provides a balm sealing cap, including an outer shell 1 and an inner shell 2. The inner shell 2 is disposed inside the outer shell 1, and the outer shell 1 and inner shell 2 are coaxially arranged. The inner shell 2 is threadedly connected to the outer shell 1 and can move up and down inside the outer shell 1. The outer shell 1 includes a first outer shell cylinder 101, a second outer shell cylinder 102, and a discharge pipe 103 connected sequentially from bottom to top. The inner diameter of the first outer shell cylinder 101 is larger than the inner diameter of the second outer shell cylinder 102, and the inner diameter of the second outer shell cylinder 102 is larger than the inner diameter of the discharge pipe 103. The inner shell 2 includes a first inner shell cylinder 201 and a second inner shell cylinder 202 connected sequentially from bottom to top. The first inner cylinder 201 has an outer diameter larger than the second inner cylinder 202, and the second inner cylinder 202 has an outer diameter larger than the plug rod 203. The first inner cylinder 201 is movably disposed inside the first outer cylinder 101, the second inner cylinder 202 is movably disposed inside both the first and second outer cylinders 101, and the plug rod 203 is movably disposed inside both the second outer cylinder 102 and the discharge pipe 103. A discharge hole 204 is provided between the top edge of the second inner cylinder 202 and the bottom edge of the plug rod 203. Function: In practical use, the bottom end of the inner shell of the ointment sealing cap can be connected and fixed to the extrusion port of the ointment receiving shell. At this time, because the plug rod blocks the discharge pipe upwards, the ointment inside the ointment receiving shell can be prevented from leaking out. When the ointment is needed, because the inner shell and outer shell are threaded together, the outer shell can be loosened upwards without completely detaching from the inner shell. At this time, the plug rod no longer blocks the discharge pipe, and the ointment receiving shell is then squeezed, so that the ointment inside the ointment receiving shell is squeezed outwards through the first inner shell cylinder, the second inner shell cylinder, the discharge hole, the second outer shell cylinder, and the discharge pipe in sequence. As can be seen from the above analysis, the inner shell and outer shell of the ointment sealing cap of this utility model do not need to be completely detached to achieve the extrusion of ointment, avoiding the loss or soiling of the ointment sealing cap.
