Description

Technical Field

[0001] The utility model relates to a packaging container, in particular to a bottle cap with a flip-open lid that does not rebound. Background Art

[0002] Existing flip-top bottle caps generally consist of a bottle cap base and a flip cover. The flip cover and the bottle cap base are connected by a flexible connecting belt. There are generally two types of connecting belt structures. One type has a crease structure provided in the middle of the connecting belt. When the flip cover is closed, the connecting belt folds along the crease structure. Due to structural problems, the maximum opening angle of the bottle cap with this connecting belt structure is generally around 135°-150°. Therefore, when users use products with this bottle cap, the bottle cap often comes into direct contact with the user's face, especially when drinking water with the bottle fully upright or nearly fully upright.

[0003] The other is a crease-free structure. When the flip cover is closed, the connecting belt is in a "U" shape. When the flip cover is opened, the connecting belt will be straightened (or nearly straightened). However, before the product is sold, the flip cover is in the closed state for a long time, which will cause a certain permanent deformation of the connecting belt. Therefore, the connecting belt will have a certain rebound force, causing the flip cover to rebound, which directly affects the user experience, such as the flip cover rebounding and hitting the user's face. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a bottle cap with a flip-open lid that does not rebound.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A bottle cap with a non-rebound flip cover, comprising a bottle cap consisting of a flip cover and a bottle cover seat, wherein the flip cover and the bottle cover seat are connected by a connecting belt, and a crease group consisting of at least two creases is provided on the connecting belt, so that the connecting belt forms at least a three-section structure, and pulling belts are provided on both sides of the connecting belt, and the two ends of the pulling belt are respectively connected to the flip cover and the bottle cover seat, and when the flip cover is opened, the connecting belt is folded along the crease group, and the flip cover is pulled by the pulling belt to fix the flip cover.

[0007] The fold group consists of a first fold close to the flip cover and a second fold close to the bottle cap seat. The first fold and the second fold separate the connecting belt into an upper belt body connected to the flip cover, a lower belt body connected to the bottle cap seat, and a middle belt body located between the first fold and the second fold.

[0008] The thickness of the upper belt gradually decreases from the flip cover toward the first fold.

[0009] The thickness of the lower belt gradually decreases from the bottle cap seat toward the second fold.

[0010] The thickness of the middle belt body gradually increases from the first folds and the second folds on both sides toward the middle.

[0011] When the flip cover is opened, the two sides of the opening of the first fold and the second fold move closer to each other until they abut against each other, which is the maximum opening angle of the flip cover.

[0012] The connection point between the connecting belt and the flip cover is located at any one of the upper end, middle end and lower end of the flip cover.

[0013] The pulling belt and the connecting belt are an integrated structure.

[0014] The pulling belt and the connecting belt are separate structures, and a gap groove is provided between the pulling belt and the connecting belt.

[0015] The connection point between the connecting belt and the bottle cap seat is located at any one of the upper end, middle end and lower end of the bottle cap seat.

[0016] The pulling belt is a curved structure.

[0017] The connecting belt is a curved structure.

[0018] The beneficial effects of the present invention are as follows: the flip cover and the bottle cap seat are connected by a connecting belt, and a crease group consisting of at least two creases is provided on the connecting belt, so that the connecting belt forms at least a three-section structure, and a pulling belt is provided on both sides of the connecting belt, and the two ends of the pulling belt are respectively connected to the flip cover and the bottle cap seat. When the flip cover is opened, the connecting belt is folded along the crease group, and the flip cover is pulled by the pulling belt to fix the flip cover, which can effectively solve the problem that the connecting belt has a rebound force and causes the flip cover to hit the user's face. At the same time, the opening angle of the flip cover can be greatly increased to about 270°, which can easily solve the problem that the flip cover directly contacts the user's face when the user is drinking water.

[0028] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0029] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0030] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0031] Reference Figure 1-8 , a bottle cap with a non-rebound flip cover, comprising a bottle cap consisting of a flip cover 1 and a bottle cover seat 2, wherein the flip cover 1 and the bottle cover seat 2 are connected by a connecting belt 3, and a crease group consisting of at least two creases is provided on the connecting belt 3, so that the connecting belt 3 forms at least a three-section structure, and a pulling belt 5 is provided on both sides of the connecting belt 3, and the two ends of the pulling belt 5 are respectively connected to the flip cover 1 and the bottle cover seat 2. When the flip cover 1 is opened, the connecting belt 3 is folded along the crease group, and the flip cover 1 is pulled by the pulling belt 5 to fix the flip cover 1, which can effectively solve the problem that the connecting belt has a rebound force and the flip cover is slapped on the user's face. At the same time, the opening angle of the flip cover can be greatly increased to about 270° (such as Figure 6-8 ), which can easily solve the problem of direct contact between the flip cover and the user's face when drinking water.

[0032] The fold group consists of a first fold 41 close to the flip cover 1 and a second fold 42 close to the bottle cap seat 2. The first fold 41 and the second fold 42 separate the connecting belt 3 into an upper belt body 31 connected to the flip cover 1, a lower belt body 32 connected to the bottle cap seat 2, and a middle belt body 33 located between the first fold 41 and the second fold 42.

[0033] The first fold 41 and the second fold 42 can be linear grooves with a smaller width or groove structures with a relatively larger width. The first fold 41 and the second fold 42 can be straight line structures or arc structures. In addition, the first fold 41 and the second fold 42 can be groove structures with a larger width, so that the first fold 41 and the second fold 42 are connected to form the same fold.

[0034] When the external force opens the flip cover 1 around 180 degrees, the connecting belt 3 will change from a folded state (i.e., the state when the flip cover 1 is closed) to a straightened state. Since the pulling belt 5 will limit the range of motion of the flip cover 1, in fact, when the flip cover 1 is opened to about 150 degrees, the pulling belt 5 is in a straightened state, thereby limiting the flip cover 1 from continuing to flip backward. At this time, it is necessary to apply a greater force to forcibly stretch the pulling belt 5 so that the flip cover 1 can continue to flip backward. When the flip cover 1 is opened to 180 degrees, the pulling belt 5 is stretched to its longest state (when the pulling belt 5 is stretched to this state, there is still room for stretching, and it is within the range of elastic deformation, so as to avoid the pulling belt 5 being unable to return after being stretched). Therefore, the flip cover 1 is within the range of 150°-180°, and since the connecting belt 3 is not disconnected as a whole, the middle part of the connecting belt 3 will be in a relatively squeezed state (that is, the upper belt body 31 moves toward the lower belt body 32, and the lower belt body 32 moves toward the upper belt body 31, and the middle belt body 33, the first fold 41 and the second fold 42 will change accordingly). The thickness of the upper belt body 31 gradually decreases from the flip cover 1 to the first fold 41, and the thickness of the lower belt body 32 gradually decreases from the bottle cap seat 2 to the second fold 42, so that the upper belt body 31 and the lower belt body 32 can be more easily deformed, so that the flip cover 1 can be more easily folded to a state greater than 180°.

[0035] When the flip cover 1 is opened more than 180 degrees, the pulling belt 5 retracts, thereby continuing to flip the flip cover 1 backward until the pulling belt 5 retracts to the initial state. At this time, the flip cover 1 is in the normal opening state (such as Figure 5-Figure 7 shown).

[0036] The thickness of the middle band 33 gradually increases from the first folds 41 and the second folds 42 on both sides toward the middle, thereby increasing the strength between the middle band 33 and preventing the upper band 31 and the lower band 32 from squeezing each other when the flip cover 1 is in the range of 150°-180°, causing the middle band 33 to undergo irreversible deformation, thereby affecting the opening and closing of the flip cover 1. For example, when the middle band 33 is squeezed, an arch is formed in the middle position, which will cause the distance between the first fold 41 and the second fold 42 to be shortened, thereby shortening the entire connecting band 3, making it impossible for the flip cover 1 to be smoothly closed.

[0037] When the flip cover 1 is opened, the two sides of the opening of the first fold 41 and the second fold 42 are close to each other until they abut against each other, which is the maximum opening angle of the flip cover 1. The two sides of the first fold 41 and the second fold 42 can be perpendicular to the bottom of the fold, or can form an obtuse angle structure or an acute angle structure with the bottom of the fold. When it is an obtuse angle structure, the two sides of the opening of the fold are close to each other until the distance of abutment is larger, and the angle of the flip cover 1 is larger. Conversely, when it is an acute angle structure, the angle of the flip cover 1 is smaller. It can be adjusted according to the actual bottle structure and the scope of use. For example, for a seasoning bottle, the flip cover 1 will not appear when it is used. To solve the problem on the user's face, the opening angle of the flip cover 1 can be relatively smaller. For example, for a beverage bottle, the opening angle of the flip cover 1 can be relatively larger. At the same time, it needs to be appropriately adjusted according to the diameter (width) of the bottle body. For example, the ratio of the bottle body to the bottle mouth is relatively small in the common mineral water bottles on the market. When the flip cover 1 is opened to about 270°, the flip cover 1 and the bottle body will not abut against each other. For example, when 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 and the upper part of the bottle body will abut against each other, making it impossible to reach the maximum opening angle, thereby easily rebounding.

[0038] According to different bottle body structures, the sizes of the lower belt body 32, the upper belt body 31 and the middle belt body 33 are adaptively changed, and the position distance between the first fold 41 and the second fold 42 is specially designed according to the structure of the bottle body.

[0039] The connection point between the connecting belt 3 and the flip cover 1 is located at any one of the upper end, middle end and lower end of the flip cover 1 .

[0040] The middle belt body 33 may have a uniform thickness throughout, or may have two ends that are thicker than the middle portion, so that the middle belt body 33 has a curved structure.

[0041] The first fold 41 and the second fold 42 are locations where the connecting belt 3 is relatively thin.

[0042] Embodiment 1: The pulling belt 5 and the connecting belt 3 are an integrated structure, which is simpler in structure.

[0043] Example 2: The pulling belt 5 and the connecting belt 3 are split structures, and a gap groove 6 is provided between the pulling belt 5 and the connecting belt 3 to separate the pulling belt 5 and the connecting belt 3 to avoid mutual influence when the flip cover 1 is opened. For example, when the flip cover 1 is opened, the pulling belt 5 will be forcibly stretched. If the pulling belt 5 and the connecting belt 3 are connected together, the connecting belt 3 will also be stretched synchronously. At the same time, since the pulling belt 5 and the connecting belt 3 are equivalent to a connecting belt with a larger width, the range of elastic deformation is reduced, and the pulling belt 5 may even be directly broken.

[0044] like Figure 5-7 The connection point between the connecting belt 3 and the bottle cap seat 2 is located at any one of the upper end, middle end and lower end of the bottle cap seat 2.

[0045] The pulling belt 5 is a curved structure, which can have only one curve or be composed of multiple curves in opposite directions, such as a wave structure; the curved structure can be curved in the left and right directions or in the front and back directions. By bending, the length of the pulling belt 5 can be increased, and the extended length can be further increased.

[0046] The connecting belt 3 is a curved structure, which is based on the same principle as the curved structure of the pulling belt 5. The curved structures of the connecting belt 3 and the pulling belt 5 are similar in shape, ensuring the consistency of the overall appearance and avoiding the situation where the pulling belt 5 has a multi-layer wavy structure and the connecting belt 3 has a single curved structure.
