DETAILED DESCRIPTION
[0027] The core of the present application is to provide a cap to reduce the difficulty of opening the cap and improve the applicability of the cap.
[0028] Another core of the present application is to provide a packaging container with the above-mentioned cap.
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0030] A cap with a small diameter is generally provided for a stand-up pouch or a special-shaped pouch due to the production line and technical limitations. When the cap is in use, it is difficult to open the cap due to the rotation force, and it is not applicable to children and other people with low rotation force.
[0031] Therefore, as shown in the drawings, Figure 1 the embodiment of the present application discloses a cap, which comprises a cover body 100. By providing a plurality of rotating surfaces 103 connected at a preset included angle, the connection position of the adjacent two rotating surfaces 103 can be used as a stress point when the cap is screwed, and a convex rib 104 for increasing friction is arranged on each rotating surface 103, so that the phenomenon of slipping during screwing the cap can be prevented, and the cap can be unscrewed only with a small rotation force, thereby reducing the difficulty of opening the cap and improving the applicability of the cap.
[0032] The cap disclosed by the embodiment of the present application will be specifically explained and described below. Figures 1 to 5 The cap disclosed by the embodiment of the present application will be specifically explained and described below.
[0033] As shown in Figure 1 and Figure 2 , the cover 100 has a small-diameter end 101 and a large-diameter end 102 arranged oppositely, a plurality of rotation surfaces 103 are arranged between the small-diameter end 101 and the large-diameter end 102, and adjacent two rotation surfaces 103 are connected at a preset included angle, and a plurality of convex edges 104 are arranged on each rotation surface 103, and the convex edges 104 extend from the small-diameter end 101 to the large-diameter end 102. The number of rotation surfaces 103 can be 3, 4, 5 or more, and the number of convex edges 104 on each rotation surface 103 can be one, two, three, four or more, so as to increase the friction when the cap is screwed. By arranging a plurality of rotation surfaces 103 connected at a preset included angle, the connection position of adjacent two rotation surfaces 103 can be used as a force point when the cap is screwed, and the convex edges 104 arranged on each rotation surface 103 can increase the friction, so as to prevent the phenomenon of slipping when the cap is screwed, and only a small rotation force is needed to unscrew the cap, thereby reducing the difficulty of opening the cap and improving the applicability of the cap.
[0034] In some embodiments, as shown in Figure 1 and Figure 3 , the cross-sectional shape of the cover 100 can adopt an octagonal cross-section, and the cover 100 has two opposite rotation surfaces 103. Meanwhile, as shown in Figure 3 , the maximum distance b between the two opposite rotation surfaces 103 can be 18.26mm-18.56mm, so that more convex edges 104 can be arranged on the cover 100 with a larger diameter, so as to increase the friction when the cap is screwed. Alternatively, as shown in Figure 2 and Figure 3 , the cover 100 has 8 rotation surfaces 103, and 5 convex edges 104 can be arranged on each rotation surface 103, the outer diameter D of the large-diameter end 102 of the cover 100 can be 19.65mm-19.95mm, and the height h of the cover 100 can be 17.95mm-18.35mm.
[0035] In some embodiments, as shown in Figure 3 , the end face of the small-diameter end of the cover 100 can adopt an octagonal shape, and the convex edges 104 on the rotation surface 103 extend from the small-diameter end 101 to the large-diameter end 102, so that the cover 100 can achieve the purpose of preventing slipping when the cap is screwed in the height direction, so that the small-diameter end of the cover 100 can adapt to children and other people with lower rotation force. Alternatively, as shown in Figure 3As shown, the shape of the rotating surface 103 can adopt an isosceles trapezoid, and the preset included angle a between two adjacent rotating surfaces 103 can be not less than 60°. When the cross-sectional shape of the cover body 100 adopts an octagonal cross-section, the preset included angle a between two adjacent rotating surfaces 103 can be 135°. Of course, the preset included angle between two adjacent rotating surfaces 103 can be, but is not limited to, 135°. When the cross-sectional shape of the cover body 100 adopts a pentagonal cross-section, the preset included angle can be 108°. Meanwhile, an arc-shaped chamfer can be arranged at the connecting position of two adjacent rotating surfaces 103 to improve the comfort of screwing the cap.
[0036] In some embodiments, as shown in Figure 1 and Figure 3 , in order to facilitate the screwing of the cap, a direction mark 1011 facilitating the screwing of the cap is arranged on the end surface of the small-diameter end 101 of the cover body 100, so that the phenomenon of screwing in the wrong direction when screwing the cap can be effectively prevented, and the efficiency and convenience of opening the cover are improved. Meanwhile, as shown in Figure 4 and Figure 5 , an inner plug 108 capable of sealing the mouth of the packaging container is further arranged in the inner cavity of the cover body 100, and the inner plug 108 is arranged at the small-diameter end 101 of the cover body 100, so that when the cap is arranged at the opening of the packaging container, the inner plug 108 can be inserted into the mouth of the packaging container to achieve the sealing effect of the packaging container.
[0037] In some embodiments, as shown in Figure 1 and Figure 2 , a theft-proof ring 105 is arranged at the large-diameter end 102 of the cover body 100. The theft-proof ring 105 can be composed of at least two ring members 106, and two adjacent ring members 106 can be fixedly connected through a connecting key 107. Meanwhile, as shown in Figure 4 , a hook portion 1061 can be arranged on the ring member 106, and the direction of the hook portion 1061 is consistent with the opening direction of the cap to limit the reverse rotation of the cap. As shown in Figure 2 , the connecting key 107 can include a notch 1071 and a connecting bridge 1072, and the notch 1071 faces the outer side of the ring member 106, and the notch 1071 extends to the side of the connecting bridge 1072 close to the small-diameter end 101 of the cover body 100, i.e., the upper side of the connecting bridge 1072 (viewing angle) to make the release of the pressure in the packaging container controllable through the notch 1071 when the cap is opened, preventing the cap from being ejected due to the sudden release of the internal pressure when opened, thereby improving the safety of the packaging container.
