Description
Technical Field
The invention relates to the technical field of beverage bottle caps, in particular to a suction nozzle screw cap of a self-supporting bag.
Background
The self-supporting bag is a flexible packaging bag which is popular at present and is often applied to packaging of liquids such as detergents, beverages, medicines and the like. The common self-supporting bag with the suction nozzle structure in the market at present is provided with the suction nozzle screw cap at the top end or the side edge of the self-supporting bag, so that the self-supporting bag is convenient to pour or absorb and can be repeatedly closed and opened.
When the suction nozzle of the self-standing bag is unscrewed, the bag body of the self-standing bag or the sealing part of the self-standing bag and the screw cap is usually required to be held by one hand, and the screw cap is unscrewed by the other hand, but because the bag body of the self-standing bag is softer, the sealing part is too small, and the screw cap is also small, the screw cap cannot be unscrewed easily due to no strength, or the liquid in the bag overflows due to too strong unscrewing, so that good use experience cannot be brought to a user.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the invention provides a suction nozzle screw cap of a self-standing bag.
The utility model adopts the following technical scheme:
the utility model provides a suction nozzle spiral cover of self-reliance bag, includes spiral cover 1, suction nozzle 2 and ferrule 3, spiral cover 1 includes enclosing cover 11 and inner cup 12, 11 covers of enclosing cover are located the upper end outside of inner cup 12, and with 12 hot melts of inner cup are connected, the cross-sectional area of enclosing cover 11 is greater than the cross-sectional area of inner cup 12, the outer wall of enclosing cover 11 is equipped with anti-skidding line 111, 11 inside hollow out construction 112 that are equipped with of enclosing cover, 12 inside walls of inner cup are equipped with the internal thread, spiral cover 1 the inner cup 12 with 2 threaded connection of suction nozzle.
Preferably, the cross section of the outer cover 11 is a square with rounded corners, and the anti-slip threads 111 are arranged on the outer sides of the rounded corners of the square.
Preferably, the suction nozzle 2 comprises a water drinking portion 21, a threaded portion 22, a first flange 23, a second flange 24 and a sealing portion 25 from top to bottom, the outer side wall of the water drinking portion 21 is smooth, the outer side wall of the threaded portion 22 is provided with an external thread, the hoop 3 is sleeved between the first flange 23 and the second flange 24, and the inner cover 12 of the screw cap 1 is fixedly connected with the hoop 3 through a connecting glue point.
After the technical scheme is adopted, compared with the background art, the utility model, have following advantage:
the suction nozzle screw cap of the utility model increases the friction between the screw cap and the hand while enlarging the inner diameter of the screw cap and increasing the moment by making the cross section area of the outer cap larger than that of the inner cap and arranging the anti-skid lines outside the screw cap, thereby the screw cap is easier to unscrew and the problems of labor waste and liquid overflow when screwing the cap are solved; in addition, the spiral cover adopts a hollow design, so that the spiral cover has the characteristic of attractive appearance while saving materials.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
As shown in fig. 1, the screw cap for a suction nozzle of a self-standing bag in the present embodiment comprises a screw cap 1, a suction nozzle 2 and a hoop 3, wherein the screw cap 1 comprises an outer cap 11 and an inner cap 12, the outer cap 11 is sleeved outside the upper end of the inner cap 12 and is connected with the inner cap 12 in a hot melting manner, and the cross-sectional area of the outer cap 11 is larger than that of the inner cap 12, so that the torque of the outer cap 11 can be increased, the screw cap can be more easily unscrewed, and the effects of saving labor and preventing liquid from overflowing are achieved. As shown in fig. 2, in this embodiment, the cross section of the outer cap 11 is square with rounded corners, the rounded corners can prevent sharp corners from cutting hands, the hand feeling during screwing is improved, and the outer wall of the outer cap 11 at the rounded corners is provided with anti-slip lines, so that the friction force is further increased, the hands are prevented from sliding during screwing, and the screwing is easier. Here, the cross section of the outer lid 11 is not limited to a square shape with rounded corners, but may be other shapes such as a diamond shape, a parallelogram shape, a triangle shape, and the like.
In addition, the outer cover 11 in this embodiment is provided with a hollow structure 112, the hollow structure is formed by connecting four stacked circular rings to the inner side of a square with rounded corners, and hollow structures with other shapes may be used.
As shown in fig. 3, the suction nozzle 2 comprises a water drinking portion 21, a threaded portion 22, a first flange 23, a second flange 24 and a sealing portion 25 from top to bottom, the outer side wall of the water drinking portion 21 is smooth, and the water drinking portion is directly contacted with the nozzle when drinking, so that the lip portion is prevented from being scratched due to the design of the smooth outer wall. The outer side wall of the threaded part 22 is provided with an external thread, the inner side wall of the inner cover 12 of the screw cap 1 is provided with an internal thread, the inner cover 12 of the screw cap 1 is in threaded connection with the suction nozzle 2, the hoop 3 is sleeved between the first flange 23 and the second flange 24, the radius of the first flange 23 and the radius of the second flange 24 are slightly larger than that of the hoop 3, so that the movement of the hoop 3 is limited between the first flange 23 and the second flange 24, the inner cover 12 of the screw cap 1 and the hoop 3 are fixedly connected through a connecting glue point, the connecting glue point is twisted off when the screw cap is screwed, the hoop 3 is still limited between the first flange 23 and the second flange 24, the screwing-out of the screw cap is realized, and the hoop 3 can be used for judging whether the screw cap is unscrewed once.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also covered by the protection scope of the present invention.
