A powder storage bottle cap for preventing misoperation

Abstract

In order to prevent users from operating incorrectly, the present invention proposes a powder storage type bottle cap that prevents misoperation. When the upper cover body and the lower cover body are connected in the initial state of rotation, the second anti-reversal barb structure and the third anti-reversal barb structure are matched and connected, and the first anti-reversal barb structure and the fourth anti-reversal barb structure are matched and connected; to prevent the upper cover body and the lower cover body from twisting backwards, when the tear ring of the upper cover body is torn off, the first anti-reversal barb structure and the fourth anti-reversal barb structure are still matched and connected, and still have the anti-reversal function. When the upper cover body and the lower cover body are connected in the rotation use state, the first anti-reversal barb structure and the third anti-reversal barb structure are matched and connected to form an anti-reversal function. The two layers of anti-reversal barb structure of the upper cover body and the two layers of anti-reversal barb structure of the lower cover body are double-layered to prevent reverse unscrewing. The powder storage type bottle cap that prevents misoperation has a simple structure, is easy to operate, and has a relatively low manufacturing cost.

Description

Technical Field

[0001] The invention relates to the fields of mixed beverages, foods, medicines, cosmetics, milk powder formulas, nutrients, supplements, mixed glues, chemistry, etc., and more specifically, to a powder storage bottle cap that can prevent misoperation. Background Art

[0002] Many products currently sold on the market are in the form of solvents and need to be mixed with some liquid before use. These products include: mixed beverages, food, medicine, cosmetics, milk powder formula, nutritional products, supplements, mixed glue, etc. These products are used after mixing with solvents and solutions, but they cannot maintain activity, stability, effective time, and strength for a long time after mixing. If they are separated, they can be stored for a long time. This requires a kind of packaging that can be separated and convenient for users to carry during use, simple and humanized.

[0003] The existing storage type bottle cap has the following problems when in use:

[0004] 1. The existing reservoir-type bottle caps have poor sealing properties, and long-term storage can easily cause the materials in the reservoir to become damp, resulting in agglomeration;

[0005] 2. The existing reservoir-type bottle caps require hot melting of the seal during assembly, which will affect the activity of some probiotics;

[0006] 3. The existing reservoir-type bottle cap has a complicated assembly process between components, which increases the cost;

[0007] 4. The overall structural design is complex and difficult for users to use; for example: a. The push-type reservoir-type bottle cap has too much resistance when puncturing, which is inconvenient to use; b. The rotary puncture reservoir-type bottle cap has moderate force when puncturing, but the existing rotary puncture reservoir-type bottle cap will appear in a state of separation of the two cap bodies when misoperated, causing confusion for users. Summary of the invention

[0008] In view of this, in order to prevent the user from making a wrong operation, the present invention proposes a powder storage type bottle cap that prevents wrong operation.

When the tear ring 208 of the upper cover body is torn off, the second anti-reversal barb structure 107 and the third anti-reversal barb structure 204 are matched and connected. Separated, the first anti-reversal barb structure 106 and the fourth anti-reversal barb structure 205 are still matched and connected, and still have the anti-reverse twisting function, when the upper cover body 100 and the lower cover body 200 are connected in a rotational use state, the first anti-reversal barb structure 106 and the third anti-reversal barb structure 204 are matched and connected to form an anti-reversal twisting function, and the two layers of anti-reversal barb structure of the upper cover body 100 and the two layers of anti-reversal barb structure of the lower cover body 200 are double-layered to prevent reverse unscrewing, and the powder storage type bottle cap that prevents misoperation has a simple structure, is easy to operate, and has a relatively low manufacturing cost.

When the upper cover body 100 and the lower cover body 200 are connected in the initial rotation state, the second anti-reversal barb structure 107 and the third anti-reversal barb structure 204 are matched and connected, and the first anti-reversal barb structure 106 and the fourth anti-reversal barb structure 205 are matched and connected; when the tear ring 208 of the upper cover body 100 is torn off, when the upper cover body 100 and the lower cover body 200 are connected in the rotation use state, the first anti-reversal barb structure 106 and the third anti-reversal barb structure 204 are matched and connected.

[0048] The first anti-reversal barb structure 106, the second anti-reversal barb structure 107, the third anti-reversal barb structure 204 and the fourth anti-reversal barb structure 205 are all composed of a plurality of convex ribs 109. The plurality of convex ribs 109 on the same anti-reversal barb structure are arranged in pairs. The convex ribs 109 on the first anti-reversal barb structure 106 and the second anti-reversal barb structure 107 are evenly distributed along the inner diameter of the upper cover outer cover 101.

[0050] The convex rib 109 includes a first end face 1091 and a second end face 1092. When the upper cover body 100 and the lower cover body 200 are connected in the initial state of rotation, the first end face 1091 of the convex rib 109 of the second anti-reversal barb structure 107 is in contact and matched with the first end face 1091 of the convex rib 109 of the third anti-reversal barb structure 204, and the first end face 1091 of the convex rib 109 of the first anti-reversal barb structure 106 is in contact and matched with the first end face 1091 of the convex rib 109 of the fourth anti-reversal barb structure 205, so as to prevent the upper cover body and the lower cover body from rotating in the opposite direction. When the tear ring 208 is torn off, the first end face 1091 of the second anti-reversal barb structure 107 and the first end face 1091 of the third anti-reversal barb structure 204 are disconnected, and the first end face 1091 is in contact and matched with the third anti-reversal barb structure. The first end face 1091 of the rib 109 of the barb structure 204 is still in contact and matched connection, and still has the anti-twisting function. When the upper cover body 100 is rotated, the second end face 1092 of the first anti-reversal barb structure 106 crosses the second end face 1092 of the fourth anti-reversal barb structure 205. Finally, the first end face 1091 of the first anti-reversal barb structure 106 is matched and connected with the first end face 1091 of the third anti-reversal barb structure 204 to form an anti-reversal mechanism. The angle B formed by the first end face 1091 of each rib 109 and the outer wall of the connecting ring 201 or the upper cover outer cover 101 ranges from 45° to 90°; the angle A formed by the second end face 1092 of each rib 109 and the outer wall of the connecting ring 201 or the upper cover outer cover 101 ranges from 110° to 160°.

[0051] A bottom cover diaphragm 206 is provided at the lower end of the connecting ring 201. The bottom cover diaphragm 206 and the connecting ring 201 are integrally formed. The connecting ring 201 and the bottom cover diaphragm 206 form an open cavity structure. The bottom cover diaphragm 206 and the lower cover body 200 are made of PE material. A connecting layer 210 is provided at the connection between the bottom cover diaphragm 206 and the inner wall of the connecting ring 201, and a positioning groove 209 is provided on the connecting layer 210.

[0052] The upper end of the bottom cover film 206 is provided with a first puncture structure 207, and the extension of the upper cover hollow structure 104 is provided with a second puncture structure 108. The first puncture structure 207 punctures the sealing sheet 105 during the process of the upper cover body 100 and the lower cover body 200 rotating and connecting, and the range of the rotation angle is 120°-900°. The sealing sheet 105 is made of a material with good barrier properties and is easy to be punctured. The thickness of the sealing sheet 105 ranges from 0.01mm to 0.5mm. During the rotation of the upper cover body 100 and the lower cover body 200, the connecting layer 210 on the bottom cover film 206 is punctured. The range of the rotation angle is between 180°-1440°. The thickness of the bottom cover film 206 The thickness range is 0.2-2.5mm; the thickness range of the connecting layer 210 is between 0.03mm-0.8mm. When the piercing teeth of the second piercing structure 108 rotate to the positioning groove 209, the rotation of the bottle cap stops, and the positioning groove 209 is not pierced by the piercing teeth of the second piercing structure 108, ensuring that the connecting layer 210 does not fall off completely. The rotation of the bottle cap stops between the lower end of the upper cover 101 and the upper end of the lower cover 203 are connected to each other, and the rotation stops. At the same time, the first end face 1091 of the rib 109 of the first anti-reversal barb structure 106 and the first end face 1091 of the rib 109 of the third anti-reversal barb structure 204 are in contact and engaged to prevent reversal.

The setting of the handle position is convenient for the user to tear open the tear ring 208, and the outer wall of the upper cover outer cover 101 of the upper cover body 100 is provided with an anti-slip surface 102, which increases the friction between the user's hand and the upper cover body 100 during use.

[0054] The working principle of the present invention is as follows: when the upper cover 100 is connected to the lower cover 200 in the initial state of rotation, the second anti-reversal barb structure 107 and the third anti-reversal barb structure 204 are matched and connected, and the first anti-reversal barb structure 106 and the fourth anti-reversal barb structure 205 are matched and connected to prevent the upper cover 100 from being reversely twisted with the lower cover 200. When the tear ring 208 of the upper cover is torn off, the second anti-reversal barb structure 107 and the third anti-reversal barb structure 204 are separated, and the first anti-reversal barb structure 106 and the fourth anti-reversal barb structure 205 are matched and connected. 6 and the fourth anti-reversal barb structure 205 are still matched and connected, and still have the anti-reverse twisting function. When the upper cover body 100 and the lower cover body 200 are connected in a rotational use state, the first anti-reversal barb structure 106 and the third anti-reversal barb structure 204 are matched and connected to form an anti-reversal twisting function. The two layers of anti-reversal barb structure of the upper cover body 100 and the two layers of anti-reversal barb structure of the lower cover body 200 are double-layered to prevent reverse unscrewing. The powder storage type bottle cap that prevents misoperation has a simple structure, is easy to operate, and has a relatively low manufacturing cost.
