[0033] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.
[0034] refer to Figures 1 to 8 As shown, the utility model discloses a discharging structure of a plastic packaging container, comprising a container 1, a discharging head 2 and a cover body 3;
[0035] The discharging end of the container 1 is provided with a blocking column 11 and a discharging port 12 located around the blocking column 11;
[0036] The discharge head 2 is axially movable and sleeved on the discharge end of the container 1, and is provided with a discharge port 21 opposite to the blocking column 11, and an anti-drop hook structure is provided between the discharge head 2 and the container 1; the blocking column 11 opens or blocks the discharge port 21 as the discharge head 2 moves axially;
[0037] The cover body 3 completely covers the discharge head 2 and is sleeved on the discharge end of the container 1 . The cover body 3 , the container 1 and the discharge head 2 are in a tight fitting assembly relationship.
[0038] Through the above solution, the utility model makes the cover body 3 tightly fit with the container 1 and the discharge head 2 at the same time. Figure 6 When not in use, the three can remain relatively fixed, the structure is relatively stable, and the container 1 is not prone to leakage; see Figure 7 and Figure 8When the user needs to open the lid for use, the cover body 3 can be first separated from the discharge end of the container 1 and drive the discharge head 2 to move axially, so that the blocking column 11 of the container 1 is separated from the discharge port 21 of the discharge head 2, and then after the discharge head 2 moves a certain distance, the hook structure limits the further movement of the discharge head 2, so that the cover body 3 is completely separated from the discharge head 2 and the discharge port 21 is completely opened, and the contents of the container 1 can be squeezed out from the discharge port 21; or when the user needs to remove the discharge head 2, the user can hold the cover body 3 tightly to be able to pry the discharge head 2 apart from the container 1 through the cover body 3; the utility model allows the user to operate and remove the discharge head 2 while the cover body 3 covers the discharge head 2, without direct contact with the discharge head 2, to avoid dirtying the hands, and improve the user experience.
[0039] Specific embodiments of the present utility model are shown below.
[0040] There are several discharge ports 12, which are arranged at equal angles around the blocking column 11. The multiple discharge ports 12 increase the discharge flow rate of the container 1 and make it easier to extrude.
[0041] The first step 13 and the second step 14 are sequentially arranged on the circumferential surface of the discharge end of the container 1, the first step 13 is higher than the second step 14, and the outer diameter of the first step 13 is smaller than the second step 14, when the discharge head 2 is sleeved on the discharge end of the container 1, its end face movably abuts the first step 13, and when the cover body 3 is sleeved on the discharge end of the container 1, its end face movably abuts the second step 14. The first step 13 and the second step 14 can limit the assembly position of the discharge head 2 and the cover body 3, so that they can be installed in place in one step.
[0042] The discharge port 21 of the discharge head 2 is a long hole in the shape of a channel, and a limiting step 211 is provided at the end of the discharge port 21 that cooperates with the blocking column 11, and the end of the blocking column 11 is movably embedded in the limiting step 211 to achieve blocking of the discharge port 21. By designing the limiting step 211, the diameter of the feed end of the discharge port 21 can be increased, so that the blocking column 11 matched therewith can be thickened, so that the outer diameter of the blocking column 11 is larger than the inner diameter of the main part of the discharge port 21, and the sealing performance of the blocking column 11 on the feed end of the discharge port 21 is better and more stable.
[0043] Furthermore, a guiding inclined surface 212 is provided at the bottom end of the limiting step 211 , so that the blocking column 11 can be more easily aligned with and enter the feeding end of the discharge hole 21 .
[0044] The periphery of the above-mentioned discharge port 12 protrudes along the axial direction of the container 1 to form a circle of first annular wall 15, and the top outer wall of the first annular wall 15 protrudes to form a circle of first limiting ring 151; the interior of the discharge head 2 is provided with a second annular wall 22 matching the first annular wall 15, and the bottom inner wall of the second annular wall 22 protrudes to form a circle of second limiting ring 221; the second annular wall 22 is sleeved on the first annular wall 15 and the second limiting ring 221 is movably hooked on the first limiting ring 151, so as to prevent the discharge head 2 from detaching from the container 1, and the discharge head 2 can be detached from the container 1 and disassembled only when greater force is used (the force is greater than the force of opening the lid).
[0045] Furthermore, the inside of the above-mentioned discharge head 2 is provided with a third ring wall 23 located inside the second ring wall 22, and the third ring wall 23 is tightly matched with the inner wall of the first ring wall 15. By designing the third ring wall 23, a movable seal between the discharge head 2 and the container 1 is realized so that the container contents discharged from the discharge port 12 can only enter the discharge port 21 without leakage, and the third ring wall 23 and the second ring wall 22 cooperate to clamp the first ring wall 15. The first ring wall 15 is blocked by the third ring wall 23 and is not easily squeezed by the second ring wall 22 and is difficult to deform inwardly, so that the discharge head 2 and the container 1 are less likely to be loosened.
[0046] The inner wall of the discharge head 2 is provided with a guide flange 24, and the peripheral surface of the discharge end of the container 1 is provided with a guide groove 16, and the guide flange 24 is slidably fitted in the guide groove 16. Through the cooperation between the guide flange 24 and the guide groove 16, the discharge head 2 can only move axially but not rotate relative to the container 1, which can reduce the user's ineffective operation.
[0047] A circle of first grooves 31 and a circle of second grooves 32 are arranged on the inner wall of the bottom of the cover body 3, and the first groove 31 is located below the second groove 32; the peripheral surface of the discharging end of the container 1 is provided with a plurality of protrusions 17 that are movably fitted in the first grooves 31; and the peripheral surface of the discharging head 2 is provided with a convex ring 25 that is movably fitted in the second groove 32. The container 1 and the cover body 3 are tightly fitted by the protrusions 17 embedded in the first grooves 31, and the discharging head 2 and the cover body 3 are tightly fitted by the convex ring 25 embedded in the second groove 32. Compared with the convex ring 25, the fitting area between the protrusion 17 and the cover body 3 is smaller, so it is easier to loosen, and it is also suitable for the operation idea of opening the cover first and then opening the discharging port 21 (i.e. moving the discharging head 2).
[0048] Furthermore, the inner wall at the bottom of the cover body 3 is provided with a notch 33 connected to the first groove 31, and the protrusion 17 enters and exits the first groove 31 through the notch 33, making it easier to open the cover. When the protrusion 17 is misaligned with the notch 33, the axial limitation of the cover body 3 and the container 1 can be guaranteed, and when the protrusion 17 is opposite to the notch 33, the cover can be easily opened.
[0049] The discharge head 2 is provided with a discharge pipe 26 , and the discharge port 21 is arranged in the discharge pipe 26 ; a flocking sleeve inner plug 4 is sleeved on the discharge pipe 26 , and a flocking sleeve 5 is connected to the end of the flocking sleeve inner plug 4 .
[0050] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
