Description

Technical Field

[0001] This invention relates to a packaging container, and more particularly to a flip-top bottle cap that does not spring back. Background Technology

[0002] Existing flip-top bottle caps generally consist of two parts: a cap base and a flip cap. The flip cap and the cap base are connected by a flexible connecting strip. The connecting strip generally has two structures. One type has a crease structure in the middle of the connecting strip. When the flip cap is closed, the connecting strip folds along the crease structure. Bottle caps with this type of connecting strip have a limited opening angle of about 135°-150° due to the inherent limitations of the structure. Therefore, when users use products with this type of bottle cap, the bottle cap often comes into direct contact with the user's face, especially when drinking water, when the bottle is fully upright or nearly fully upright.

[0003] Another type is the crease-free structure. When the flip is closed, the connecting strip is U-shaped. When the flip is opened, the connecting strip will be straightened (or nearly straightened). However, before the product is sold, the flip is in the closed state for a long time, which will cause the connecting strip to undergo a certain degree of permanent deformation. Therefore, the connecting strip will have a certain degree of elasticity, causing the flip to bounce back, which directly affects the user's experience, such as the flip hitting the user's face. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a flip-top bottle cap that does not spring back.

[0005] The technical solution adopted by this invention to solve its technical problem is: A non-spring-loaded bottle cap includes a flip cap and a cap base. The flip cap and the cap base are connected by a connecting strap. The connecting strap has a crease group consisting of at least two creases, forming a structure of at least three segments. Pull straps are provided on both sides of the connecting strap. The two ends of the pull straps are respectively connected to the flip cap and the cap base. When the flip cap is opened, the connecting strap folds along the crease group and pulls the flip cap by the pull straps to fix the flip cap.

[0006] The crease group consists of a first crease near the flip cover and a second crease near the cap holder. The first and second creases divide the connecting strip into an upper strip connected to the flip cover, a lower strip connected to the cap holder, and a middle strip located between the first and second creases.

[0007] The thickness of the upper strap gradually decreases from the flap toward the first crease.

[0008] The thickness of the lower band gradually decreases from the bottle cap seat towards the second crease.

[0009] The thickness of the central strip gradually increases from the first and second creases on both sides toward the center.

[0010] When the flip cover is opened, the openings of the first crease and the second crease come closer together until they meet, which is the maximum opening angle of the flip cover.

[0011] The connection point between the connecting strip and the flip cover is located at any one of the upper, middle, or lower ends of the flip cover.

[0012] The traction belt and the connecting belt are an integral structure.

[0013] The traction belt and the connecting belt are separate structures, and a gap groove is provided between the traction belt and the connecting belt.

[0014] The connection point between the connecting strip and the bottle cap holder is located at any one of the upper, middle, or lower ends of the bottle cap holder.

[0015] The traction belt has a curved structure.

[0016] The connecting strip has a curved structure.

[0017] At least one scratch is provided on the connecting strip along the length direction of the crease group.

[0018] The beneficial effects of this invention are as follows: The flip cap and the bottle cap holder are connected by a connecting strap. The connecting strap is provided with a crease group consisting of at least two creases, so that the connecting strap forms a structure of at least three sections. Pull straps are provided on both sides of the connecting strap, and the two ends of the pull straps are respectively connected to the flip cap and the bottle cap holder. When the flip cap is opened, the connecting strap folds along the crease group and pulls the flip cap by the pull straps to fix the flip cap. This can effectively solve the problem of the flip cap hitting the user's face due to the elasticity of the connecting strap. At the same time, it can greatly increase the opening angle of the flip cap to about 270°, which can easily solve the problem of the flip cap directly contacting the user's face when drinking water.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0024] Reference Figure 1-8 A non-spring-loaded flip-top bottle cap includes a flip-top 1 and a cap holder 2. The flip-top 1 and the cap holder 2 are connected by a connecting strap 3. The connecting strap 3 has at least two creases forming a crease group, creating a structure of at least three segments. Pull straps 5 are provided on both sides of the connecting strap 3, with each end of the pull strap 5 connected to the flip-top 1 and the cap holder 2 respectively. When the flip-top 1 is opened, the connecting strap 3 folds along the crease group, and the pull straps 5 pull the flip-top 1, fixing it in place. This effectively solves the problem of the flip-top hitting the user's face due to the spring-loaded connecting strap, and also greatly increases the opening angle of the flip-top to approximately 270° (e.g., ...). Figure 6-8 This device can easily solve the problem of the lid coming into direct contact with the user's face when drinking water.

[0025] The crease group consists of a first crease 41 near the flip cover 1 and a second crease 42 near the bottle cap seat 2. The first crease 41 and the second crease 42 divide the connecting band 3 into an upper band 31 connected to the flip cover 1, a lower band 32 connected to the bottle cap seat 2, and a middle band 33 located between the first crease 41 and the second crease 42.

[0026] The first crease 41 and the second crease 42 can be narrow grooves or relatively wide recesses. The first crease 41 and the second crease 42 can be straight lines or curved lines. In addition, the first crease 41 and the second crease 42 can be even wider recesses, so that the first crease 41 and the second crease 42 are connected to form a single crease.

[0027] At least one scratch is provided on the connecting strip 3 along the length of the crease group. The scratch can be located on the first crease 41 and the second crease 42, that is, directly cut through the first crease 41 and the second crease 42 (the two ends are still connected; if completely cut, the flip cover 1 and the bottle cap seat 2 will separate), or it can be located outside the first crease 41 and the second crease 42. When the flip cover 1 is opened, the scratch will crack (depending on the actual structure, if the requirements of the flip cover 1 are met, the scratch may not crack; therefore, whether the scratch cracks or not when the flip cover 1 is opened, it is considered to preserve the product). This increases the extension length of the connecting strap 3, thereby further increasing the opening angle of the flap 1. It can also better accommodate creases of different widths and achieve a better flap effect (for example, the narrower the crease, the smaller the length that can be stretched, and the smaller the opening angle of the flap. If the opening angle is too large, it is easy to exceed the limit of the crease's stretchability, causing the crease to break directly. If it is combined with scratches, even if the crease is narrow, it can crack through the scratches during the flap opening process, thereby increasing the limit of the connecting strap's stretchability and achieving a better flap effect). At the same time, it can also reduce the difficulty of opening the flap 1.

[0028] When an external force opens the flap 1 to approximately 180 degrees, the connecting strap 3 changes from a folded state (i.e., the state when the flap 1 is closed) to a straightened state. Since the tension strap 5 restricts the range of motion of the flap 1, when the flap 1 is actually opened to about 150 degrees, the tension strap 5 is in a straightened state, thus limiting the flap 1 from opening further backward. At this point, greater force needs to be applied to forcibly stretch the tension strap 5, allowing the flap 1 to continue opening backward. When the flap 1 is opened to 180 degrees, the tension strap 5 is stretched to its longest state (when the tension strap 5 is stretched to this state, it still has room to be stretched further, and it is within the range of elastic deformation, to prevent the tension strap 5 from being unable to return to its original position after being stretched). (When shrinkage occurs), therefore, the flip cover 1 is within the range of 150°-180°. At the same time, since the connecting strap 3 is not broken as a whole, the middle part of the connecting strap 3 will be in a state of relative compression (that is, the upper strap 31 moves towards the lower strap 32, the lower strap 32 moves towards the upper strap 31, and the middle strap 33, the first crease 41 and the second crease 42 will change accordingly). The thickness of the upper strap 31 gradually decreases from the flip cover 1 towards the first crease 41, and the thickness of the lower strap 32 gradually decreases from the cap seat 2 towards the second crease 42, so that the upper strap 31 and the lower strap 32 can deform more easily, so that the flip cover 1 can be folded to a state greater than 180° more easily.

[0029] When the flip cover 1 is opened more than 180°, the pull strap 5 retracts, thereby continuing to flip the flip cover 1 backward until the pull strap 5 retracts to its initial state. At this point, the flip cover 1 is in its normal open state (e.g., Figures 5-7 (As shown).

[0030] The thickness of the middle strap 33 gradually increases from the first crease 41 and the second crease 42 on both sides towards the middle, increasing the strength between the middle straps 33. This prevents the upper strap 31 and the lower strap 32 from squeezing each other when the flap 1 is in the range of 150°-180°, causing irreversible deformation of the middle strap 33, which would affect the opening and closing of the flap 1. For example, when the middle strap 33 is squeezed, it forms an arch in the middle position, which will shorten the distance between the first crease 41 and the second crease 42, thereby shortening the connecting strap 3 as a whole, making it impossible for the flap 1 to be closed smoothly.

[0031] When the flip cover 1 is opened, the opening sides of the first crease 41 and the second crease 42 approach each other until they meet, which is the maximum opening angle of the flip cover 1. The opening sides of the first crease 41 and the second crease 42 can be perpendicular to the bottom of the crease, or they can form an obtuse angle or an acute angle with the bottom of the crease. When it is an obtuse angle, the distance between the opening sides of the crease and the point of contact is greater, and the angle of the flip cover 1 is larger. Conversely, when it is an acute angle, the angle of the flip cover 1 is smaller. The specific angle can be adjusted according to the actual bottle structure and the scope of use. For example, for a condiment bottle, the flip cover 1 will not tap or slam. Regarding the issue of the opening angle of the flip cover 1, it can be relatively smaller. For example, for beverage bottles, the opening angle of the flip cover 1 can be relatively larger. At the same time, it needs to be adjusted appropriately according to the diameter (width) of the bottle body. For example, for common mineral water bottles, the ratio of the bottle body to the bottle mouth is relatively small. When the flip cover 1 is opened to about 270°, the flip cover 1 will not abut against the bottle body. On the other hand, if the ratio of the bottle body to the bottle mouth is relatively large, that is, when the width of the bottle body is large, if the opening angle of the flip cover 1 is too large, the flip cover 1 will abut against the upper part of the bottle body, preventing it from reaching the maximum opening angle, and thus making it easy to spring back.

[0032] Depending on the different bottle body structures, the dimensions of the lower belt 32, upper belt 31, and middle belt 33 are adaptively changed, and the positional distance between the first crease 41 and the second crease 42 is specially designed according to the bottle body structure.

[0033] The connection point between the connecting strip 3 and the flip cover 1 is located at any one of the upper, middle, or lower ends of the flip cover 1.

[0034] The middle strip 33 can have a uniform thickness, or the thickness at both ends can be greater than that in the middle, so that the middle strip 33 has an arc-shaped structure.

[0035] The first crease 41 and the second crease 42 are the relatively thinner parts of the connecting strip 3.

[0036] Example 1: The traction belt 5 and the connecting belt 3 are an integral structure, which makes the structure simpler.

[0037] Example 2: The pulling strap 5 and the connecting strap 3 are separate structures. A gap groove 6 is provided between the pulling strap 5 and the connecting strap 3 to separate the pulling strap 5 and the connecting strap 3, so as to avoid mutual interference when the flip cover 1 is opened. If the flip cover 1 is opened, the pulling strap 5 will be forcibly stretched. If the pulling strap 5 and the connecting strap 3 are connected together, the connecting strap 3 will also be stretched synchronously. At the same time, since the pulling strap 5 and the connecting strap 3 are equivalent to a wider connecting strap, the range of elastic deformation is reduced, and it may even be directly broken.

[0038] like Figure 5-7 The connection point between the connecting strip 3 and the bottle cap seat 2 is located at any one of the upper, middle, or lower ends of the bottle cap seat 2.

[0039] The traction belt 5 has a curved structure, which can be a single bend or a combination of multiple bends in opposite directions, such as a wave structure. The curved structure can be a bend in the left-right direction or a bend in the front-back direction. By bending, the length of the traction belt 5 can be increased, thereby further increasing the extension length.

[0040] The connecting strip 3 has a curved structure, which is the same principle as the bending structure of the traction strip 5. The bending structure shape of the connecting strip 3 and the traction strip 5 is similar to that of the traction strip 5, which ensures the consistency of the overall appearance and avoids the situation where the traction strip 5 has a multi-layer wave structure while the connecting strip 3 has a single curved structure.
