Description

Technical Field

[0001] The present application relates to the field of containers, and in particular to a bottle cap and a bottle. Background Art

[0002] In order to facilitate the recycling of bottle caps, one-piece bottle caps have been widely used in the international market. One-piece bottle caps are caps that always remain on the beverage bottle. One-piece bottle caps generally include Figure 1 (That is, the publication number is KR20150106185A Figure 1 The spiral one-piece bottle cap shown in a) has the tendency for the opened portion of the bottle cap to rebound and touch the nose when used, affecting the user experience. Utility Model Content

[0003] The purpose of the present application is to provide a bottle cap and a bottle, which can prevent the bottle cap from touching the nose of the drinker after it is opened.

[0004] The embodiment of the present application is implemented as follows:

[0005] In the first aspect, the embodiment of the present application provides a bottle cap, comprising a collar, a flip cover, and a connection area. The collar is used to be sleeved outside the bottle mouth, a first tearing area is provided between the flip cover and the collar, a thread is provided inside the flip cover, and is used to be threadedly connected with the bottle mouth; the connection area comprises a connecting piece and two connecting strips connected to both sides of the connecting piece, one end of the connecting strip away from the connecting piece is connected to the collar, and a second tearing area is provided between the lower side of the connecting piece and the lower sides of the two connecting strips and the collar.

[0006] The flip cover is connected to the upper side of the connecting piece via a first weak area, the thickness of the first weak area is smaller than the thickness of the flip cover, and the bottle cap is configured such that the first tear area and the second tear area can be destroyed so that the flip cover can move upward and flip around the first weak area relative to the ring.

[0007] In the above technical solution, the collar is sleeved on the bottle mouth, and in the process of unscrewing the flip cover, the flip cover will move in the direction away from the collar, so that the first tearing area and the second tearing area are destroyed. When the first tearing area and the second tearing area are destroyed, the collar is still sleeved on the bottle mouth, and in the process of continuing to unscrew the flip cover, the distance between the flip cover and the collar and the distance between the connecting piece and the collar increase at the first tearing area and the second tearing area, and the flip cover moves up and is still connected to the collar through the connecting piece and the connecting strip, so that the flip cover can be flipped to open the bottle cap.

[0008] Since the flap and the connecting piece are connected through the first weak area, and the thickness of the first weak area is less than the thickness of the flap, the first weak area has a low strength. In the process of flipping the flap, the first weak area is prone to deformation, and the flap is prone to rotate around the first weak area at a large angle, and the rebound tendency after deformation is small. By connecting the flap and the connecting piece through the first weak area, the flap can be opened at a larger angle with a smaller rebound, and the flap is not easy to rebound and touch the user's nose when the user drinks water, thereby improving the user's experience.

[0009] In addition, since the second tearing zone between the connecting area and the ring is destroyed, the connecting piece can be turned over together during use, and the rotation axis of the connecting piece is close to the position of the second tearing zone. The connecting piece can be rotated to the lower side to contact the outer periphery of the bottle mouth, and under the action of the two connecting strips, the connecting piece is kept in a state of abutting the bottle mouth on the lower side, which can make the bottle cap difficult to rotate at the bottle mouth, thereby preventing the bottle cap from rotating and touching the user's chin when drinking water; in addition, in this state, the upper side of the connecting piece is far away from the bottle mouth, and the flip cover is connected to the upper side of the connecting piece through the first weak area. Therefore, the flip cover is also far away from the bottle mouth, further reducing the situation where the flip cover rebounds and touches the user's nose.

[0010] In combination with the first aspect, in some optional embodiments, the connecting piece is further provided with a second weak area extending along the circumference of the bottle cap, the thickness of the second weak area is less than the thickness of the flip cover, and the connecting piece is configured to be folded around the second weak area to increase the flipping angle of the flip cover relative to the ring.

[0011] In the above technical solution, since the connecting piece is provided with the second weak area, during the process of opening the flip cover, the second weak area can be deformed to make the side of the connecting piece connected to the flip cover further deviate away from the bottle mouth, so that the flip cover is opened at a greater angle, and the situation that the flip cover rebounds and touches the user's nose is further improved. In addition, when a smaller force is used, the flip cover is deformed from the first weak area, so that the flip cover can be opened at a certain angle, and then when a larger force is used, the flip cover is deformed at the first weak area and the second weak area at the same time, so that the flip cover can be opened at a larger angle. Multiple modes can be selected to open the bottle cover according to the user's usage habits or requirements, which is more convenient to use.

[0012] In combination with the first aspect, in some optional embodiments, the middle section of the second weak zone is closer to the first weak zone than the two ends.

[0013] In the above technical solution, since the middle section of the second weak area is closer to the first weak area, after the connecting piece is bent around the second weak area to increase the flipping angle of the flip cover, in addition to the force acting in the circumferential direction of the flip cover, the bottle cap also has a force acting in the direction of the collar toward the flip cover, so that the upper and lower parts of the connecting piece in the second weak area can be more easily in a static state under the action of multiple forces, that is, the connecting area is not easy to automatically rebound after being folded around the second weak area, so that the flip cover is in a position with a larger flipping angle.

[0014] In combination with the first aspect, in some optional embodiments, the middle section of the second weak zone intersects with the middle section of the first weak zone.

[0015] In the above technical solution, when the bottle cap is opened, the flip cover is deformed at the first weak area and the second weak area at the same time, and the force concentration point is located at the intersection of the middle sections of the two. The intersection is relatively concentrated, which can make the bottle cap easier to be in a static state when it is opened, and further reduce the probability of rebound. In addition, when the intersection of the first weak area and the second weak area is deformed, the edge of the connecting piece directly below the intersection is abutted against the bottle mouth, which can better prevent the flip cover from rotating and rebounding, and is more convenient to use.

[0016] In combination with the first aspect, in some optional embodiments, both ends of the second weak zone extend along an arc line to the middle section.

[0017] In the above technical solution, the two ends of the second weak area extend along the arc to the middle section, which can better fold the connecting piece along the second weak area, make it easier to deform in the second weak area, and open the bottle cap with less force. It is also easier to keep the folded state without rebounding.

[0018] In combination with the first aspect, in some optional embodiments, the first weak zone includes a first groove, a second groove and a third groove, and on the circumference of the bottle cap, the second groove is located between the first groove and the third groove, and the second groove is closer to the second tear zone than the first groove and the third groove.

[0019] In the above technical solution, since the second groove in the first weak zone is closer to the second tear zone, after the first weak zone is deformed so that the flap is further flipped relative to the connecting zone, the flap can be kept in a stationary state under multiple forces, that is, the flap can be kept in an opened state without automatically rebounding.

[0020] In combination with the first aspect, in some optional embodiments, the first groove, the second groove and the third groove are interconnected, and the first groove, the second groove and the third groove together occupy 1 / 10 to 1 / 3 of the circumference of the bottle cap.

[0021] In the above technical solution, the length of the first weak area is within the above range, which can make it easier to flip the flip cover and prevent the flip cover from automatically rebounding when in the flipped-over state, making the bottle cap more convenient to use.

[0022] In combination with the first aspect, in some optional embodiments, the connecting piece is further provided with a second weak area extending along the circumference of the bottle cap, and the connecting piece is configured to be folded around the second weak area to increase the flipping angle of the flip cover relative to the ring; the middle section of the second weak area coincides with the second groove.

[0023] In the above technical solution, the flip angle of the solution can be further increased by the second weak area. When the bottle cap is opened, the flip cover is deformed at the first weak area and the second weak area at the same time, and the force concentration point is located at the intersection of the second weak area and the second groove. The position of the intersection is relatively concentrated, which can make the bottle cap easier to be in a static state when it is opened, and further reduce the probability of rebound. In addition, when the intersection of the first weak area and the second groove is deformed, the edge of the connecting piece directly below the intersection is made to abut against the bottle mouth, which can better prevent the flip cover from rotating and rebounding, and is more convenient to use.

[0024] In combination with the first aspect, in some optional embodiments, one end of the first weak zone is connected to one end of the first tear zone, and the other end of the first weak zone is connected to the other end of the first tear zone.

[0025] In the above technical solution, since both ends of the first weak area are connected to the first tearing area, the flip cover can be turned over more easily.

[0026] In combination with the first aspect, in some optional embodiments, the first weak area occupies 1 / 10 to 1 / 3 of the circumference of the bottle cap.

[0027] When the length of the first weak area is within the above range, the flip cover can be turned over relatively easily and the flip cover will not automatically rebound when in the opened state, making the bottle cap more convenient to use.

[0028] In combination with the first aspect, in some optional embodiments, the first tear zone and the first weak zone together occupy 90% to 100% of the circumference of the bottle cap in the circumferential direction of the bottle cap.

[0029] In the above technical solution, when the proportion is greater than or equal to 90% but less than 100%, although there is a thicker part between the first tearing area and the first weak area connecting the flap and the connecting piece, the flap can still be opened relatively easily. After the flap is turned over, the force generated by the thicker part is larger, which can better keep the flap in a static state without rebounding. When the proportion is 100%, both ends of the first weak area are connected to the first tearing area. After the first tearing area is destroyed, the flap and the ring are only connected through the first weak area, which makes it easier to turn the flap.

[0030] In combination with the first aspect, in some optional embodiments, one of the connecting strips occupies 1 / 15 to 1 / 6 of the circumference of the bottle cap; and the dimension of the connecting strip in the axial direction of the bottle cap is 0.4 mm to 1.5 mm.

[0031] The proportion of the connecting strip in the circumferential direction of the bottle cap and the size in the axial direction are within the above ranges, so that the connecting strip can be deformed relatively easily, and thus the connecting piece can move with the bottle cap in a direction away from the collar during the process of unscrewing the bottle cap. The connecting piece can be turned over as a whole to a state where the lower side abuts against the outer periphery of the bottle mouth, and the connecting strip can maintain the connecting piece in this state.

[0032] In combination with the first aspect, in some optional embodiments, the first tear zone includes a first section and a second section, the first section extends along the circumference of the bottle cap, the second section extends in a direction away from the ring, and the two ends of the first section are each connected to a second section; the first weak zone is located between the two second sections.

[0033] The connecting piece is located between the two second sections and is connected to the flip cover through the second section; in the axial direction of the bottle cap, the connecting strip is located between the first section and the second tearing area.

[0034] In combination with the first aspect, in some optional embodiments, the first weak area and the second weak area are arranged on the inner side of the connecting piece.

[0035] In the above technical solution, by arranging the first weak area and the second weak area on the inner side of the connecting piece, the appearance of the bottle cap can be made more complete.

[0036] In a second aspect, the present application provides a bottle, comprising a bottle body and the bottle cap provided in the first aspect, wherein the collar of the bottle cap is sleeved on the bottle mouth of the bottle body; and the flip cover covers the bottle mouth.

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0050] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0051] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0052] In the description of this application, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the application is usually placed when in use, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0053] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0054] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] The present application provides a bottle. The bottle provided in the present application may be a beverage bottle, a mineral water bottle, or other bottles that can be directly drunk or poured out of liquid. Figures 2 to 5 As shown, the bottle body 100 and the bottle cap 200 are included, and the bottle cap 200 includes a collar 210, a flip cover 220 and a connection area 230. The collar 210 is sleeved on the bottle mouth of the bottle body 100 to achieve the purpose of connecting the bottle cap 200 to the bottle body 100; the flip cover 220 covers the bottle mouth. There is a first tearing area 250 between the flip cover 220 and the collar 210, and a thread is provided in the flip cover 220, and the flip cover 220 is threadedly connected to the bottle mouth through the thread. In the process of unscrewing the flip cover 220, the flip cover 220 will move in a direction away from the collar 210, thereby destroying the first tearing area 250.

[0056] The first tearing zone 250 is a portion that will be destroyed during the initial unscrewing of the flip cover 220, so that the connection between the flip cover 220 and the collar 210 can be separated. The structure of the first tearing zone 250 can be the same as that of the tearing zone in the existing bottle cap 200, that is, the first tearing zone 250 includes a plurality of through slots, and two adjacent slots are connected only by a thin connecting rib 253, so that the connecting rib 253 is destroyed during the initial unscrewing of the flip cover 220. The first tearing zone 250 can also be different from the tearing zone structure in the prior art (for example, the structure of the first tearing zone 250 is a tear line), as long as the first tearing zone 250 can play the role of connecting the flip cover 220 and the collar 210 and be destroyed during the initial unscrewing of the flip cover 220.

[0057] like Figures 5 to 8 and Fig.10 As shown, the connection area 230 has a connection piece 232 and two connection strips 231 connected to both sides of the connection piece 232. It is not difficult to understand that the connection piece 232 is a sheet structure, which has a larger size in the axial direction and circumferential direction of the bottle cap 200 and a smaller size in the thickness of the bottle cap 200; the connection strip 231 is a strip structure, and since the bottle cap 200 is a plastic structural member, the strip structure is easily deformed during the process of unscrewing the flip cover 220. The upper side of the connection piece 232 is connected to the flip cover 220 through the first weak area 240, and the thickness of the first weak area 240 is less than the thickness of the flip cover 220, so that the first weak area 240 is easily deformed, and then the flip cover 220 can rotate relative to the connection piece 232 around the first weak area 240.

[0058] The lower side of the connecting piece 232 and the lower side of the two connecting strips 231 are connected to the ring 210 via a second tearing zone 260, wherein the second tearing zone 260 is also a structure that will be destroyed when the flip cover 220 is unscrewed for the first time. The structure of the second tearing zone 260 may be the same as or different from the structure of the tearing zone in the prior art.

[0059] It is easy to understand that when the bottle provided by the present application is used, during the process of first unscrewing the flip cover 220, the flip cover 220 and the connecting area 230 will move upward to be away from the collar 210, thereby damaging the first tearing area 250 and the second tearing area 260. Afterwards, due to the existence of the first weak area 240, the flip cover 220 can rotate around the first weak area 240 relative to the connecting piece 232 to expose the bottle mouth for drinking. Since the collar 210 and the flip cover 220 are connected through the connecting area 230, it is easy to understand that the first tearing area 250 is not closed, such as Figure 5 As shown, the first weakened area 240 is located between two ends of the first tear area 250 to enable the flip cover 220 to be turned over after the first tear area 250 is destroyed.

[0060] In some embodiments, the structural strength of the bottle cap 200 at the location of the first weak area 240 is relatively low, so the first weak area 240 is easily deformed and causes the flip cover 220 to flip over relative to the connecting piece 232. For example, the thickness of the bottle cap 200 at the first weak area 240 is less than the thickness of the flip cover 220. A specific implementation method is to set a groove structure at the location where the connecting piece 232 and the flip cover 220 are connected to form the first weak area 240. The groove structure can be formed during the injection molding process of the bottle cap 200, or it can be a notch engraved on the bottle cap 200 after the bottle cap 200 is molded. The first weak area 240 can also be a thinner area formed between the connecting piece 232 and the flip cover 220 during the molding process of the bottle cap 200. Among them, Figure 8 As shown, the flip cover 220 includes a circular cover sheet located at the top and directly disposed toward the bottle mouth, and an annular structure disposed at the edge of the cover sheet. The thickness of the flip cover 220 may be the thickness of the unthreaded portion of the annular structure.

[0061] When the bottle provided by the above embodiment is used, on the one hand, the flip cover 220 can be turned over so that the flip cover 220 rotates around the first weak area 240 relative to the connecting piece 232 and is thus turned over a greater distance; on the other hand, the connecting piece 232 can be turned over so that the connecting piece 232 is turned over to the lower side to contact the outer periphery of the bottle mouth, and under the action of the two connecting strips 231, the connecting piece 232 is kept in a state of contacting the bottle mouth at the lower side (such as Figure 5 In this state, the upper side of the connecting piece 232 is far away from the bottle mouth, and the flip cover 220 is connected to the upper side of the connecting piece 232 through the first weak area 240. Therefore, the flip cover 220 is also far away from the bottle mouth, further reducing the flip cover 220 touching the user's nose.

[0062] It is easy to understand that, since the first weak area 240 connects the flip cover 220 and the connecting piece 232, and the flip cover 220 is turned around the first weak area 240 to expose the bottle mouth, the first weak area 240 extends along the circumferential direction of the bottle cap 200, and may also be accompanied by a small amount of displacement along the axial direction of the bottle cap 200 during the circumferential extension process. In the embodiment where the first weak area 240 only extends along the circumferential direction of the bottle cap 200, the extension trajectory of the first weak area 240 is an arc.

[0063] Please refer to Figure 5 and Fig. 9 As shown, in some embodiments, the first weak zone 240 includes a first groove 241, a second groove 242 and a third groove 243. The cross-sections of the first groove 241, the second groove 242 and the third groove 243 can be rectangular, V-shaped, or other shapes as long as they can reduce the strength of the location of the first weak zone 240.

[0064] Further, in an embodiment where the first weak area 240 extends only along the circumferential direction of the bottle cap 200 , the first groove 241 , the second groove 242 and the third groove 243 are located on the same arc on the circumference of the bottle cap 200 .

[0065] Further, if Fig. 9 In some embodiments where the first weak zone 240 also extends in the circumferential direction and the axial direction of the bottle cap 200, the first groove 241, the second groove 242 and the third groove 243 all extend in the circumferential direction of the bottle cap 200, but there is a height position deviation in the axial direction of the bottle cap 200. On the circumference of the bottle cap 200, the first groove 241, the second groove 242 and the third groove 243 are arranged in sequence (that is, the second groove 242 is located between the first groove 241 and the third groove 243 in the circumferential direction of the bottle cap 200), and the second groove 242 is closer to the second tearing zone 260 than the first groove 241 and the third groove 243, that is, the second groove 242 is located in a relatively lower arc on the circumference of the bottle cap 200, and the first groove 241 and the third groove 243 are located in a relatively upper arc on the circumference of the bottle cap 200. In this embodiment, after the flip cover 220 is flipped around the first weak area 240 relative to the connection area 230, in addition to the force acting on the flip cover 220 in the circumferential direction, the bottle cap 200 also has a force acting on the direction of the collar 210 toward the flip cover 220, so that the flip cover 220 can be in a static state under multiple forces to improve the rebound of the flip cover 220 after being opened. In the axial direction of the bottle cap 200, the distance between the first groove 241 and the second groove 242 can be equal to the distance between the third groove 243 and the second groove 242, or it can be different from the distance between the third groove 243 and the second groove 242.

[0066] Further, if Figure 5 and Figure 7 In some other embodiments where the first weak area 240 also extends along the circumferential direction and the axial direction of the bottle cap 200, the first groove 241, the second groove 242 and the third groove 243 may extend along both the circumferential direction and the axial direction of the bottle cap 200. For example, in some embodiments, the first groove 241 and the third groove 243 extend along both the circumferential direction and the axial direction of the bottle cap 200; the second groove 242 extends only along the circumferential direction of the bottle cap 200.

[0067] In some embodiments, the first groove 241, the second groove 242 and the third groove 243 may be interconnected, and the first groove 241, the second groove 242 and the third groove 243 together occupy 1 / 10 to 1 / 3 of the circumference of the bottle cap 200, and the specific proportion may be 1 / 10, 1 / 9, 1 / 8, 1 / 7, 1 / 6, 1 / 5, 1 / 4 or 1 / 3. That is, the first weak area 240 together occupies 1 / 10 to 1 / 3 of the circumference of the bottle cap 200, which can be understood as the ratio of the arc length of the projection of the first weak area 240 to the circumference of the projection of the bottle cap 200 along the axis direction of the bottle cap 200 is 1 / 10 to 1 / 3. It is not difficult to understand that the smaller the ratio is, the easier it is to flip the flip cover 220, but the flip cover 220 is not easy to stay still at the preset position after being flipped and is easy to rebound; the larger the ratio is, the harder it is to flip the flip cover 220, but the flip cover 220 is more likely to stay still and not rebound after being flipped. When the ratio is in the range of 1 / 10 to 1 / 3, the flip cover 220 can be flipped relatively easily and the flip cover 220 can stay still after being flipped. In other embodiments, the ratio can also be outside 1 / 10 to 1 / 3.

[0068] In some other embodiments, there is a gap between the first groove 241, the second groove 242 and the third groove 243 along the circumference of the bottle cap 200. In this embodiment, the first weak area 240 is the area between the end of the first groove 241 and the end of the third groove 243, that is, the first weak area 240 includes the first groove 241, the second groove 242 and the third groove 243, and also includes the gap between the first groove 241 and the second groove 242, and the gap between the second groove 242 and the third groove 243; the thickness of the first weak area 240 is not less than the thickness of the bottle cap 200 at all positions, but the thickness at the positions where the first groove 241, the second groove 242 and the third groove 243 are located is less than the thickness of the bottle cap 200, and the thickness of the gap between the first groove 241, the second groove 242 and the third groove 243 can be equal to the thickness of the bottle cap 200.

[0069] Furthermore, in order to better flip the flip cover 220, one end of the first weak zone 240 is connected to one end of the first tear zone 250, and the other end of the first weak zone 240 is connected to the other end of the first tear zone 250, that is, the first weak zone 240 is between both ends of the first tear zone 250, which makes it easier to flip the flip cover 220.

[0070] In some embodiments, based on the ratio of the arc length of the projection of the first weak zone 240 to the circumference of the projection of the bottle cap 200 being 1 / 10 to 1 / 3, the first tear zone 250 and the first weak zone 240 together account for 90% to 100% of the circumference of the bottle cap 200 in the circumferential direction of the bottle cap 200, and specifically may account for 90%, 92%, 94%, 96%, 98% or 100%. That is, in the axial direction of the bottle cap 200, the sum of the arc lengths of the projections of the first tear zone 250 and the first weak zone 240 accounts for 90% to 100% of the circumference of the projection of the bottle cap 200. It is not difficult to understand that the larger the value, the lower the connection strength between the flip cover 220 and the connection zone 230, and the easier it is to flip the flip cover 220. In other embodiments, the proportion of the first tear zone 250 and the first weak zone 240 in the circumferential direction of the bottle cap 200 may also be less than 90%.

[0071] In an embodiment where the proportion is greater than or equal to 90% but less than 100%, Figure 5 and Figure 6 As shown, the end of the first weak area 240 is not directly connected to the first tearing area 250. There may be a region with greater strength than the first weak area 240 between the end of the first weak area 240 and the first tearing area 250, such as a region with greater thickness than the first weak area 240. In the process of flipping the flip cover 220, this region is a location with greater deformation, so the structural strength of this region is adapted to the deformation amount, so that the region is not damaged when the flip cover 220 is flipped multiple times, and the flip cover 220 can be better maintained in a static state without rebounding.

[0072] In an embodiment where the sum of the arc lengths of the projections of the first tear zone 250 and the first weak zone 240 accounts for 100% of the circumference of the projection of the bottle cap 200, as Fig. 9 As shown, both ends of the first weak zone 240 are directly connected to the first tear zone 250. In this embodiment, the flip cover 220 can be flipped over relatively easily, and because the ratio of the arc length of the projection of the first weak zone 240 to the circumference of the projection of the bottle cap 200 is 1 / 10 to 1 / 3, the first weak zone 240 can also remain intact after the flip cover 220 is flipped over multiple times.

[0073] In some embodiments of the present application, Figures 5 to 7 and Fig. 9As shown, the connecting piece 232 is also provided with a second weak area 2321 extending along the circumference of the bottle cap 200. It is not difficult to understand that due to the existence of the second weak area 2321, the connecting area 230 can be folded around the second weak area 2321, that is, the part located on the upper side of the second weak area 2321 can be rotated around the second weak area 2321 relative to the part located on the lower side of the second weak area 2321. Since the flip cover 220 is connected to the upper side of the connecting piece 232, the connecting piece 232 is folded around the second weak area 2321, so that the part of the connecting piece 232 located on the upper side of the second weak area 2321 is deflected in the direction away from the bottle mouth, which can make the flip cover 220 deviate further in the direction away from the bottle mouth, thereby increasing the flip angle of the flip cover 220 relative to the collar 210, which can further improve the situation that the flip cover 220 touches the user's nose. Among them, the upper part of the second weak zone 2321 is the part of the connecting piece 232 located between the first weak zone 240 and the second weak zone 2321, and the lower part of the second weak zone 2321 is the part of the connecting piece 232 located between the second weak zone 2321 and the second tearing zone 260.

[0074] Furthermore, the second weak area 2321 may also adopt a structure with lower structural strength to facilitate deformation. For example, the thickness of the connecting piece 232 in the second weak area 2321 is less than the thickness of the flip cover 220. Similarly, the second weak area 2321 may be a groove structure provided in the connecting area 230, and the groove structure may be formed during the injection molding process of the bottle cap 200, or may be a notch engraved on the bottle cap 200 after the bottle cap 200 is molded.

[0075] In some embodiments, the thickness of the second weak area 2321 is less than the thickness of the first weak area 240, that is, the thickness of the connection area 230 at the location of the second weak area 2321 is less than the thickness at the location of the first weak area 240, and the thickness at the location of the second weak area 2321 is less than the thickness at most other locations in the connection area 230. For example, when both the first weak area 240 and the second weak area 2321 are groove structures, the groove depth of the first weak area 240 is greater than the groove depth of the second weak area 2321. In this embodiment, the structural strength of the first weak area 240 is lower than that of the second weak area 2321. Therefore, in the process of flipping the flip cover 220, the first weak area 240 can be deformed first, while the second weak area 2321 is less likely to be deformed. When the flip cover 220 rotates around the first weak area 240 at a large angle, the second weak area 2321 can stabilize the opening angle of the flip cover 220.

[0076] It is not difficult to understand that as the number of second weak areas 2321 in the connecting piece 232 increases, the angle at which the flip cover 220 can be flipped relative to the ring 210 increases, and the user can adjust the flip angle of the flip cover 220 according to his or her preferences. In some embodiments, the number of second weak areas 2321 can be one, and in other embodiments, the number of second weak areas 2321 can be two or more. Of course, it can also be as follows Fig.10 As shown, the second weak area 2321 may not be provided in the connecting piece 232 .

[0077] The circumferential extension of the second weak zone 2321 along the bottle cap 200 includes the case where the second weak zone 2321 only extends along the circumferential direction of the bottle cap 200; it also includes the case where the second weak zone 2321 mainly extends along the circumferential direction of the bottle cap 200 and also extends along the axial direction of the bottle cap 200.

[0078] In the embodiment where both the second weak area 2321 and the first weak area 240 extend only along the circumference of the bottle cap 200 , the extension trajectories of the first weak area 240 and the second weak area 2321 are parallel to each other and are arcs at different axial positions of the bottle cap 200 .

[0079] In some embodiments, the second weak area 2321 also extends along the axial direction of the bottle cap 200, such as Figure 5 and Fig. 9 As shown, the middle section of the second weak area 2321 is closer to the first weak area 240 than the two ends, that is, in the circumferential direction of the bottle cap 200, at least some areas on both sides of the middle section of the second weak area 2321 are farther from the first weak area 240. In this embodiment, since the middle section of the second weak area 2321 is closer to the first weak area 240, after the connecting piece 232 is bent around the second weak area 2321 to increase the flip angle of the flip cover 220, the upper and lower parts of the connecting piece 232 in the second weak area 2321 can be more easily in a static state under the action of multiple forces, that is, the connecting area 230 can be less likely to automatically rebound after being folded around the second weak area 2321, so that the flip cover 220 is in a position with a larger flip angle.

[0080] Further, in some embodiments, the middle section of the second weak area 2321 intersects with the middle section of the first weak area 240. Since the middle section of the second weak area 2321 intersects with the middle section of the first weak area 240, the size of the connecting piece 232 located on the upper side of the second weak area 2321 is smaller, and the distance between the top of the connecting piece 232 and the collar 210 is smaller, that is, the distance between the first weak area 240 and the collar 210 is smaller, which can effectively improve the interference between the connecting piece 232 and the thread.

[0081] In the above-mentioned embodiment where the first weak zone 240 includes the first groove 241, the second groove 242 and the third groove 243 arranged in sequence, the second groove 242 is the middle section of the first weak zone 240, and the middle section of the second weak zone 2321 intersects with the second groove 242. In some embodiments, the middle section of the second weak zone 2321 only intersects with a portion of the second groove 242; in other embodiments, such as Fig. 9 As shown, the middle section of the second weak area 2321 coincides with the second groove 242 .

[0082] Further, if Figure 5 and Fig. 9 As shown, the two ends of the second weak area 2321 extend along the arc to the middle section of the second weak area 2321, so as to facilitate the folding of the connecting piece 232 along the second weak area 2321, and make it easier for the connecting piece 232 to remain in the folded state without rebounding. In some embodiments, the arc is an elliptical arc, and in other embodiments, the arc can also be a circular arc or a part of a conic curve. Further, in combination with the above-mentioned first groove 241 and the third groove 243 extending not only along the circumference of the bottle cap 200 but also along the axial direction of the bottle cap 200, the first weak area 240 and the second weak area 2321 can form a structure approximately in the shape of an "X".

[0083] In some embodiments of the present application, the first weak area 240 and the second weak area 2321 are disposed on the inner side of the connecting piece 232, wherein the first weak area 240 is disposed on the inner side of the connecting piece 232 means that the thinner area in the first weak area 240 is lower than the inner surface of the connecting piece 232. In this embodiment, the first weak area 240 and the second weak area 2321 will not affect the appearance of the bottle cap 200.

[0084] In some embodiments of the present application, Figure 7 and Figure 8 As shown, the first tear zone 250 includes a first section 251 and a second section 252 ; the first section 251 extends along the circumference of the bottle cap 200 , and the second section 252 extends away from the ring 210 , and a second section 252 is connected to each end of the first section 251 .

[0085] The first section 251 may extend only along the circumferential direction of the bottle cap 200, or may extend mainly along the circumferential direction of the bottle cap 200 and also extend in the axial direction of the bottle cap 200. The second section 252 may extend only along the axial direction of the bottle cap 200 away from the collar 210, and accordingly, the connecting piece 232 is generally a rectangular sheet structure; the second section 252 may also extend along the axial direction of the bottle cap 200 and also extend in the circumferential direction of the bottle cap 200, and accordingly, the connecting piece 232 is generally a trapezoidal sheet structure.

[0086] Furthermore, the connecting piece 232 and the first weak area 240 are both located between the two second sections 252. When the bottle cap 200 is not opened for the first time, the flip cover 220 and the collar 210 are connected via the first section 251; the second section 252 is located between the connecting piece 232 and the flip cover 220.

[0087] The first section 251 has the aforementioned fine connecting rib 253 for connecting the flip cover 220 and the collar 210; the second section 252 may be only a through slot, which does not actually connect the connecting piece 232 and the flip cover 220, or may have the aforementioned fine connecting rib 253 for connecting the flip cover 220 and the connecting piece 232. The aforementioned second section 252 is only a through slot, and the aforementioned second section 252 has the aforementioned fine connecting rib 253 for connecting the flip cover 220 and the connecting piece 232, both of which can be regarded as the connecting piece 232 being connected to the flip cover 220 through the second section 252.

[0088] In some embodiments, the first weak area 240 may be located between the ends of the two second segments 252, or between the middles of the two second segments 252. Accordingly, the first weak area 240 may be connected to the end of the second segment 252 away from the first segment 251, or may be connected to the middle of the second segment 252.

[0089] Furthermore, in the axial direction of the bottle cap 200 , the connecting strip 231 is located between the first section 251 and the second tearing area 260 .

[0090] Further, if Figure 8As shown, the dimension L of the connecting strip 231 on the circumference of the bottle cap 200 accounts for 1 / 15 to 1 / 6 of the circumference of the bottle cap 200, and can be specifically 1 / 15, 1 / 12, 1 / 10, 1 / 8, 1 / 6, etc.; and the dimension s of the connecting strip 231 in the axial direction of the bottle cap 200 is 0.4 mm to 1.5 mm, and can be specifically 0.4 mm, 0.5 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm. Within the above numerical range, the connecting strip 231 is relatively slender, has a relatively soft structure, and is prone to elastic deformation. Therefore, the connecting strip 231 can make the connecting piece 232 move within a reasonable range along the axial direction of the bottle cap 200, and it will not be difficult to unscrew the flip cover 220 from the bottle mouth because the movement range of the connecting piece 232 is too small, nor will the connecting piece 232 move too freely because the movement range of the connecting piece 232 is too large, so that the unscrewed flip cover 220 shakes randomly, and then the flip cover 220 touches the user's nose or chin. When the size of the connecting strip 231 is within the above range, the connecting piece 232 can be rotated as a whole to a position where the lower side contacts the outer periphery of the bottle mouth, and the lower side of the connecting piece 232 abuts against the outer periphery of the bottle mouth under the action of the force generated by the deformation of the connecting strip 231, and maintains the abutting state. In the contact state, the bottle cap 200 can be restricted from rotating relative to the bottle body 100, which is convenient for the user to drink; and the upper side of the connecting piece 232 can be further away from the bottle mouth, so that the flip cover 220 can be opened at a larger angle relative to the collar 210, further preventing the flip cover 220 from touching the user and rebounding. Of course, the user does not need to flip the connecting piece 232 to the state where the lower side abuts against the outer periphery of the bottle mouth during use.

[0091] In some other embodiments, the ratio of the dimension L of the connecting strip 231 on the circumference of the bottle cap 200 to the circumference of the bottle cap 200 may also be greater than 1 / 6 or less than 1 / 15; the dimension s of the connecting strip 231 in the axial direction of the bottle cap 200 may also be less than 0.4 mm or greater than 1.5 mm.

[0092] In some embodiments, the second tear zone 260 may extend only along the circumferential direction of the bottle cap 200, or may extend mainly along the circumferential direction of the bottle cap 200, and may also extend along the axial direction of the bottle cap 200. Further, the second tear zone 260 includes a segment X, a segment Y, and a segment Z, wherein the segment X and the segment Z are each used to connect a connecting strip 231 and the collar 210, and the segment Y is used to connect the lower side of the connecting piece 232 and the collar 210. Preferably, the segment X and the segment Z are located on the same arc on the circumference of the bottle cap 200. Further, the segment X, the segment Y, and the segment Z are all located on the same arc on the circumference of the bottle cap 200.

[0093] Furthermore, in order to facilitate unscrewing the bottle cap 200 , anti-slip ribs may be provided on the outer periphery of the flip cover 220 .

[0094] by Figures 5 to 7 The structure of the bottle cap 200 is as follows:

[0095] The bottle cap 200 includes a collar 210, a flip cover 220, and a connection area 230. The collar 210 is used to be sleeved on the bottle mouth of the bottle body 100 to achieve the purpose of connecting the bottle cap 200 to the bottle body 100; the flip cover 220 covers the bottle mouth. There is a first tearing area 250 between the flip cover 220 and the collar 210, and a thread is provided in the flip cover 220, and the flip cover 220 is threadedly connected to the bottle mouth through the thread.

[0096] The connection area 230 has a connection piece 232 and two connection strips 231 connected to both sides of the connection piece 232. The lower side of the connection piece 232 and the lower sides of the two connection strips 231 are connected to the collar 210 through the second tearing area 260. The upper side of the connection piece 232 is connected to the flip cover 220 through the first weak area 240. The thickness of the first weak area 240 is less than the thickness of the flip cover 220, so that the first weak area 240 is easily deformed, and the flip cover 220 can rotate relative to the connection piece 232 around the first weak area 240. The connection piece 232 is also provided with a second weak area 2321 extending along the circumference of the bottle cap 200. The portion of the connection piece 232 located on the upper side of the second weak area 2321 can rotate around the second weak area 2321 relative to the portion located on the lower side of the second weak area 2321.

[0097] The first weak area 240 includes a first groove 241 , a second groove 242 and a third groove 243 which are sequentially arranged, and the second groove 242 is closer to the second tearing area 260 than the first groove 241 and the third groove 243 .

[0098] The optional usage of the bottle cap 200 is as follows:

[0099] When the bottle cap 200 is closed on the bottle mouth, the state is as follows Figure 2 As shown, in the process of unscrewing the bottle cap 200, the bottle cap 200 rotates as a whole relative to the bottle mouth, and the flip cover 220 gradually moves upward, so that the first tearing area 250 is destroyed. The connecting area 230 also moves upward with the flip cover 220, so that the second tearing area 260 is destroyed, and the connecting piece 232 in the connecting area 230 moves upward with the flip cover 220, and the connecting strip 231 is connected to the connecting piece 232 at one end and connected to the collar 210 at the other end, so the connecting strip 231 is gradually deformed during the upward movement of the connecting piece 232.

[0100] After the threads of the flip cover 220 are completely separated from the threads of the bottle mouth, the flip cover 220 can be flipped in a direction away from the bottle mouth, such as Figure 3As shown, the first weak area 240 will deform adaptively so that the flip cover 220 can be flipped open to a larger angle. And because the second groove 242 is closer to the second tearing area 260, after the first weak area 240 deforms so that the flip cover 220 is further flipped relative to the connecting area 230, the flip cover 220 can be kept in a stationary state under multiple forces, that is, the flip cover 220 can be kept in an opened state without automatically rebounding.

[0101] If the user thinks that the opening angle of the flip cover 220 is not enough, the user can fold the connecting piece 232 along the second weak area 2321. Figure 4 As shown, the opening angle of the flip cover 220 can be further increased. After the connecting piece 232 is bent around the second weak area 2321 to increase the flip angle of the flip cover 220, in addition to the force acting in the circumferential direction of the flip cover 220, the bottle cap 200 also has a force acting in the direction of the collar 210 toward the flip cover 220, so that the parts of the connecting piece 232 on the upper and lower sides of the second weak area 2321 can be easily in a static state under the action of multiple forces, that is, the connecting area 230 is not easy to automatically rebound after being folded around the second weak area 2321, so that the flip cover 220 is in a position with a larger opening angle.

[0102] The user can also flip the connecting piece 232 according to actual needs to make the connecting piece 232 Figure 2 The inner side shown is turned toward the outer periphery of the bottle mouth. Figure 4 The lower side is shown in contact with the outer periphery of the bottle mouth, and abuts against the outer periphery of the bottle mouth under the action of the connecting strip 231, so as to further increase the angle of the flip cover 220 being flipped open, and better prevent the flip cover 220 from rotating and rebounding.

[0103] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
