Description
Technical Field
The utility model relates to the field of daily necessities, in particular to bottle cap.
Background
At present, bottled liquid daily necessities such as disinfectant, cleaning agent and the like are generally opened or unscrewed to pour out liquid in a bottle by mounting a bottle cap on the bottle opening when in use. However, in order to prevent the product from spilling during transportation, many manufacturers add a sealing gasket for sealing the bottle mouth, and when the bottle is opened, consumers need to tear the sealing gasket by hand after opening the bottle cap. However, since one side of the sealing gasket is in direct contact with the liquid in the bottle, a consumer can easily touch the hand when tearing the sealing gasket, the liquid such as disinfectant or the like has strong oxidizing property and strong corrosivity, the hand can be easily affected once being touched by the hand, the liquid in the bottle can be easily splashed when the sealing gasket is torn, the opening exposed after the sealing gasket is torn is generally large, when the consumer needs to use a small amount of liquid, a small amount of liquid is difficult to pour through the large opening, and inconvenience is brought to daily use.
Disclosure of Invention
The invention provides a bottle cap which can effectively seal a bottle body and is convenient to use, and aims to solve the technical problem that a sealing gasket for preventing splashing is arranged on the bottled liquid at present, so that the bottle cap is inconvenient to unseal.
In order to achieve the technical purpose, the technical proposal of the utility model is that,
the utility model provides a bottle cap, includes upper cover and lower cover, lower cover and upper cover be top confined tubular structure, the lower part of lower cover inner wall is equipped with the external screw thread of internal thread in order to match the bottleneck, the upper portion of lower cover outer wall is equipped with the external screw thread, the lower part of upper cover inner wall be equipped with the external screw thread of internal thread in order to match the lower cover outer wall, the roof center of lower cover is equipped with the opening, the upper cover is stopped up the opening behind the external screw thread of screw in lower cover.
According to the bottle cap, the opening of the lower cap is provided with the outward tubular protrusion, and the top of the tubular protrusion is blocked by the upper cap after the upper cap is screwed into the external thread of the lower cap.
The bottle cap is characterized in that the upper cap is provided with a columnar protrusion facing the inner part of the lower cap at a position corresponding to the tubular protrusion of the lower cap, and the outer diameter of the columnar protrusion is matched with the inner diameter of the tubular protrusion so as to block the tubular protrusion.
According to the bottle cap, the annular horizontal protrusion facing to the center is arranged on the top of the internal thread of the inner wall of the lower cap, the width of the horizontal protrusion is matched with the width of the edge of a bottle mouth, and the edge of the annular horizontal protrusion is provided with a cylindrical protrusion facing to the bottom of the bottle.
The inner diameter and the outer diameter of the lower cover provided with the external thread part are smaller than those of the internal thread part, the outer diameter of the upper cover is consistent with that of the internal thread part of the lower cover, and the inner diameter of the upper cover is matched with that of the external thread part of the lower cover.
In the bottle cap, stripes for increasing friction are arranged on the outer wall of the upper cover.
The technical effect of the utility model lies in, through setting up double-deck bottle lid from top to bottom, can prevent that the bottle from leading to liquid to splash in the bottle on the way in the transportation, the consumer can not have the problem of hand direct contact bottle interior liquid when opening the bottle lid simultaneously, and double-deck bottle lid is equipped with big or small opening, and the consumer can select the opening size as required, prevents the waste in the use.
The present invention will be further explained with reference to the accompanying drawings.

Detailed Description
Referring to fig. 1 and 2, the utility model discloses an upper cover and lower cover, lower cover and upper cover are top confined tubular structure, and the lower part of lower cover inner wall is equipped with the external screw thread of internal thread in order to match the bottleneck, and the upper portion of lower cover outer wall is equipped with the external screw thread, and the lower part of upper cover inner wall is equipped with the external screw thread of internal thread in order to match the lower cover outer wall, and the roof central authorities of lower cover are equipped with the opening, and the upper cover plugs up the opening behind the external screw thread of screw in lower cover.
In order to facilitate diversion, the opening of the lower cover is provided with a tubular protrusion facing outwards, and the top of the tubular protrusion is blocked by the upper cover after the upper cover is screwed into the external thread of the lower cover. Therefore, a small amount of liquid can be poured out only by unscrewing the upper cover, and the requirement of daily small-dose use is met.
In order to enhance the sealing effect, the upper cover is provided with a columnar protrusion facing the inner part of the lower cover at the corresponding position of the tubular protrusion of the lower cover, and the outer diameter of the columnar protrusion is matched with the inner diameter of the tubular protrusion so as to block the tubular protrusion.
In order to better fix the lower cover on the bottle mouth, the inner wall of the lower cover is provided with an annular horizontal protrusion towards the center at the top of the internal thread, the width of the horizontal protrusion is matched with the width of the edge of the bottle mouth, and the edge of the annular horizontal protrusion is provided with a cylindrical protrusion towards the bottom of the bottle. This enables the lower cap to better seal the bottle mouth.
In order to ensure that the bottle cap and the bottle body are as thick as possible. The inner diameter and the outer diameter of the lower cover provided with the external thread part are smaller than those of the internal thread part, the outer diameter of the upper cover is consistent with that of the internal thread part of the lower cover, and the inner diameter of the upper cover is matched with that of the external thread part of the lower cover.
In order to facilitate the bottle cap to be unscrewed by a consumer, the outer wall of the upper cover is provided with stripes for increasing friction.
