Description

Technical Field

[0001] This utility model relates to the technical field of easy-tear aluminum-plastic combination caps, specifically an easy-tear aluminum-plastic combination cap. Background Technology

[0002] Aluminum-plastic composite caps are widely used in the pharmaceutical industry, mainly for packaging medicines such as infusion bottles, vaccine bottles, and injection bottles.

[0003] For example, an aluminum-plastic combination cap with announcement number "CN207060810U" includes a force-applying cap, a sealing cap, and a rubber cap. The force-applying cap is connected to the sealing cap through a central protrusion ring passing through the central hole of the sealing cap. By setting a first, second, third, and fourth notch on the sealing cap, the user can easily open the aluminum-plastic combination cap sealed on the medicine bottle. However, in the use of the aluminum-plastic combination cap, only the edge of the plastic cap protrudes from the top of the aluminum cap. This requires the user to hold the edge and push or lift it upwards. The edge of the plastic cap can easily cause pressure pain to the hand, and in severe cases, it can easily cause scratches to the hand, increasing the danger of opening and closing the aluminum-plastic combination cap and affecting its normal use. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of increased danger in opening and closing aluminum-plastic composite covers, which affects their normal use, and to propose an easy-tear aluminum-plastic composite cover.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an easy-tear aluminum-plastic composite cover, including a top cover and a groove. The top cover has a groove on its front side. Control structures are connected to the left and right sides of the inner wall of the groove. A circular plate is fixed to the lower front side of the top cover. The rear end face of the circular plate fits against the front side of the control structure. A stopper is fixed to the rear end face of the top cover.

[0007] Preferably, the control structure includes vertical rods and curved blocks. The ends of the two vertical rods are rotatably connected to the left and right sides of the inner wall of the slot, respectively. The outer wall of the vertical rods is fixedly connected to the inner wall of the curved block, and a bracket is fixedly connected to the inner side of the curved block.

[0008] Preferably, the lower front surface of the bracket is in contact with the upper rear end surface of the circular plate.

[0009] Preferably, the front side of the circular plate is machined with a groove.

[0010] Preferably, a cap is attached to the rear end face of the top cover, and a round opening is machined on the front side of the cap.

[0011] Preferably, the inner wall of the circular opening is inserted into the outer wall of the plug.

[0012] The present invention provides an easy-tear aluminum-plastic composite cover with the following advantages: By controlling the structure to pull the support outward, the support, under force, causes the curved block to flip outward. At the same time, the vertical rod on the inner wall of the curved block rotates on the inner wall of the groove. At this time, the support applies a push-pull to the circular plate. Since the outer wall of the circular plate is machined with grooves, the circular plate will break as the pushing force increases. At this time, the support disengages from the inside of the groove. Then, the support continues to be pulled, causing the support, along with the curved block and the vertical rod, to move the top cover forward, causing the top cover and the plug to disengage from the circular opening, thus completing the opening of the aluminum-plastic composite cover. This achieves easy tearing of the aluminum-plastic composite cover, eliminates the danger of opening and closing the aluminum-plastic composite cover, and ensures the normal use of the aluminum-plastic composite cover.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] Please see Figures 1-4 In this embodiment, an easy-tear aluminum-plastic composite cover includes a top cover 1 and a groove 3. The top cover 1 has a groove 3 machined on its front side. Control structures 2 are connected to the left and right sides of the inner wall of the groove 3, respectively. A circular plate 4 is fixedly attached to the lower front side of the top cover 1. The rear end face of the circular plate 4 is in contact with the front side of the control structure 2. A plug 6 is fixedly attached to the rear end face of the top cover 1. Both the top cover 1 and the plug 6 are made of plastic.

[0021] The control structure 2 includes a vertical rod 201 and a curved block 202. The ends of the two vertical rods 201 are rotatably connected to the left and right sides of the inner wall of the slot 3, respectively. The vertical rod 201 is a pin that can rotate in the circular groove of the inner wall of the slot 3. The outer wall of the vertical rod 201 is fixedly connected to the inner wall of the curved block 202. A bracket 203 is fixedly connected to the inner side of the curved block 202. Both the curved block 202 and the bracket 203 are made of plastic. The lower front side of the bracket 203 is attached to the upper rear end face of the circular plate 4.

[0022] By controlling the structure 2 to pull the bracket 203 outward, the bracket 203 is forced to rotate outward along with the curved block 203. At the same time, the vertical rod 201 on the inner wall of the curved block 202 rotates on the inner wall of the slot 3. At this time, the bracket 203 applies a push and pull to the circular plate 4. Since the outer wall of the circular plate 4 is machined with a groove 5, it will break as the pushing force on the circular plate 4 increases. At this time, the bracket 203 disengages from the inside of the slot 3. Then, the bracket 203 continues to be pulled, so that the bracket 203, together with the curved block 202 and the vertical rod 201, moves the top cover 1 forward, so that the top cover 1 and the plug 6 disengage from the circular opening 8, thus completing the opening of the aluminum-plastic composite cover. This makes the aluminum-plastic composite cover easy to tear, eliminates the danger of opening and closing the aluminum-plastic composite cover, and ensures the normal use of the aluminum-plastic composite cover.

[0023] The front of the round plate 4 has a groove 5. The round plate 4 is a plastic round plate. The rear end face of the top cover 1 is fitted with a cap 7. The cap 7 is made of aluminum. The front of the cap 7 has a round opening 8. The inner wall of the round opening 8 is inserted into the outer wall of the plug 6.

[0024] Working principle:

[0025] Installation of aluminum-plastic composite cover:

[0026] Apply adhesive to the inner wall of the cap 7, then fit the inner wall of the cap 7 onto the outer wall of the designated bottle opening, so that the adhesive inside the cap 7 adheres to the bottle opening, thus completing the installation of the aluminum-plastic combination cap.

[0027] Aluminum-plastic composite cap usage:

[0028] Pull the support 203 outward, and the support 203, under force, causes the curved block 203 to flip outward. At the same time, the vertical rod 201 on the inner wall of the curved block 202 rotates on the inner wall of the groove 3. At this time, the support 203 applies a push and pull to the circular plate 4. Since the outer wall of the circular plate 4 is machined with a groove 5, it will break as the pushing force on the circular plate 4 increases. At this time, the support 203 disengages from the inside of the groove 3. Then, continue to pull the support 203, so that the support 203, together with the curved block 202 and the vertical rod 201, moves the top cover 1 forward, so that the top cover 1, along with the stopper 6, disengages from the circular opening 8, completing the opening of the aluminum-plastic combination cap and making the aluminum-plastic combination cap easy to tear. At this time, the liquid inside the bottle can be poured out through the circular opening in front of the cap 7.

[0029] Example 2:

[0030] Please see Figures 1-4 In this embodiment, an easy-tear aluminum-plastic composite cover also includes a collar 9, the inner wall of which is fixedly connected to the rear of the outer wall of the top cover 1.

[0031] Working principle:

[0032] When the control structure 2 is damaged due to a manufacturing defect, the hand can contact the bottom of the collar 9 and push the collar 9 forward to move the top cover 1 forward. The collar 9 increases the contact area behind the top cover 1, effectively reducing the pressure sensation when pushing.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
