Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

Referring to Figures 2, 3 and 4, a preferred embodiment of the safety bottle cap of the present invention is suitable for being fixedly combined with an opening 91 of a container 9 . The safety bottle cap is made of plastic material, and includes a lower cover body 2 , an upper cover body 3 connected with the lower cover body 2 in a detachable manner, and a safety mechanism 4 .

The lower cover body 2 of this embodiment includes a lower cover wall 21 fixedly combined with the opening 91 of the container 9 . The lower cover wall 21 has a horizontal base wall portion 211 defining a discharge opening 212 , and a surrounding wall portion 213 extending downward from the periphery of the base wall portion 211 . The surrounding wall portion 213 has an annular top ring surface 214 , and an outer surface 215 extending downward from the outer peripheral edge of the top ring surface 214 , and the outer surface 215 has an inwardly concave region 216 .

The upper cover body 3 of this embodiment includes an upper cover wall 31 corresponding to the base wall portion 211 , and an upper cover wall 31 that extends downward from the periphery of the upper cover wall 31 and can be butted up and down with the top ring surface 214 surrounding the wall portion 213 . The outer peripheral wall 32, a connecting wall 33 connected between the upper cover wall 31 and the surrounding wall 213 in a detachable manner, and a connecting wall 33 protruding from the upper cover wall 31 to the discharge opening 212 and can close the discharge opening 212. The sealing wall 34 of the opening 212, and a flip cover wall 35 protruding horizontally from the peripheral wall 32 and located on the opposite side of the sealing wall 34 with the connecting wall 33 respectively. The outer peripheral wall 32 has an outer peripheral surface 321 , and the outer peripheral surface 321 has a concave region 322 recessed inward and corresponding to the concave region 216 of the lower cover 2 .

The safety mechanism 4 of this embodiment includes a tear-off connecting portion 41 provided on the surrounding wall portion 213 of the lower cover body 2, and a tear-off connection portion 41 provided on the peripheral wall 32 of the upper cover body 3 and located in the recessed area 322. The non-return hook 42. However, in practice, the tear-off connecting portion 41 can also be arranged on the outer peripheral wall 32 of the upper cover body 3, and the non-return hook 42 can also be arranged on the surrounding wall portion 213 of the lower cover body 2, so The form disclosed in this embodiment is not limited.

The tear-off connection part 41 of this embodiment has a base plate 411, several tear-off connecting pieces 412 that connect the base plate 411 to the top ring surface 214 in a tearable manner, and a piece that penetrates the base plate 411 and provides the backstop. The hook 42 engages with the hook hole 413, an extension plate 414 integrally formed with the base plate 411 and extending toward the concave area 216 of the lower cover 2, and two spaced holes extending from the extension plate 414 toward the concave area 216. The protrusions 415 protruding integrally from the region 216 , wherein the width of each tear-off piece 412 is gradually reduced from the end connected to the substrate 411 to the end away from it. The number of the protruding grains 415 and the number of the tearing pieces 412 only need one respectively to achieve the expected purpose of this utility model.

After the safety bottle cap of this embodiment is manufactured, it is located in an unassembled position as shown in FIG. The non-return hook 42 of the safety mechanism 4 is integrally formed on the outer peripheral wall 32 of the upper cover 3 . When the safety bottle cap of the present embodiment is to be switched from the unassembled position of Fig. 2 to an unopened position shown in Fig. 3, the upper cover body 3 is first placed on the lower cover body 2, and the At the same time, the anti-return hook 42 on the upper cover 3 will gradually move down from the inner side of the base plate 411. , the safety bottle cap will be switched from the unassembled position of Fig. 2 to the unopened position of Fig. 3, and is engaged and connected by the safety mechanism 4, and the upper cover body 3 cannot be opened (as shown in Fig. 4 ) .

Referring to Figures 3, 4, and 5, when the user wants to use the filling inside the container 9, first put his fingers into the concave area 216 of the lower cover 2, and then tear off the extension plate 414 of the connecting portion 41. Pull outward along a pull-off direction 5 as shown in FIG. When the tear-off connecting portion 41 is separated from the lower cover body 2, the safety bottle cap will be converted from the unopened position shown in FIG. 4 to an unsealed position shown in FIG. Upper cover body 3. It is further explained that the bumps 415 provided on the extension plate 414 of the present invention can provide anti-slip effect when pulling the extension plate 414, so that the fingers can hold the extension plate 414 more firmly and Pull outward, and in addition, the width of the tear-off link 412 is gradually reduced from the end connected to the base plate 411 to the far end. This design allows consumers to tear off the The connecting piece 412 is torn off. In addition, the color of the tear-off connecting portion 41 in this embodiment is different from the color of the upper cover 3 and the lower cover 2 , so as to increase the effect of identification, but the implementation is not limited thereto.

As can be seen from the above description, when the safety bottle cap of the present utility model is in the unopened position, the upper cover body 31 cannot be opened. 2 away from the lower cover. Therefore, when consumers purchase commodities, they can easily identify whether the safety bottle cap has been unsealed as long as they observe from the appearance of the safety bottle cap whether the tear-off connecting portion 41 is still connected to the lower cover body 2. The new safety bottle cap does have the effect of making it easy to identify the unsealing situation from the appearance and improving the safety of use.
