Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of packaging containers, in particular to a bottle cap without springback. BACKGROUND

[0002] The existing flip cap bottle cap is generally composed of bottle cap seat and flip cap, and the flip cap and the bottle cap seat are connected by flexible connecting band. The structure of the connecting band generally has two types. One is provided with a crease structure in the middle of the connecting band. When the flip cap is closed, the connecting band is folded along the crease structure. The bottle cap with this type of connecting band has a limit angle of about 135°-150° due to the problem of its structure itself. Therefore, when the user uses the product with this type of bottle cap, the bottle cap often directly contacts the face of the user, especially when the user drinks water, the bottle is completely upright or close to the state of complete upright.

[0003] The other type is without crease structure. When the flip cap is closed, the connecting band is in the shape of "U". When the flip cap is opened, the connecting band is straightened (or close to the state of straightening). However, before the product is sold, the flip cap is in the closed state for a long time, which causes the connecting band to have a certain permanent deformation. Therefore, the connecting band has a certain springback force, which causes the flip cap to spring back and directly affects the user's experience, such as the flip cap springing back and hitting the face of the user. SUMMARY

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a bottle cap without springback.

[0005] The utility model solves the technical problems by adopting the following technical scheme:

[0006] A bottle cap without springback, which is composed of a flip cap and a bottle cap seat, the flip cap and the bottle cap seat are connected by a connecting band, the connecting band is provided with a crease group composed of at least two creases, so that the connecting band is formed into an at least three-section structure, the two sides of the connecting band are provided with pulling bands, the two ends of the pulling bands are connected with the flip cap and the bottle cap seat respectively, when the flip cap is opened, the connecting band is folded along the crease group, and the flip cap is fixed by pulling the flip cap through the pulling bands.

[0007] The crease group is composed of a first crease close to the flip cap and a second crease close to the bottle cap seat, the first crease and the second crease separate the connecting band into an upper band body connected with the flip cap, a lower band body connected with the bottle cap seat, and a middle band body between the first crease and the second crease.

[0008] The thickness of the upper band body gradually decreases from the flip cap to the first crease.

[0009] The thickness of the lower band gradually decreases from the bottle cap seat to the second crease.

[0010] The thickness of the middle band gradually increases from the first crease and the second crease on both sides to the middle.

[0011] When the flip cover is opened, the opening sides of the first crease and the second crease approach each other until they are closed, which is the maximum opening angle of the flip cover.

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

[0013] The pulling band and the connection band are an integral structure.

[0014] The pulling band and the connection band are a separate structure, and a gap groove is arranged between the pulling band and the connection band.

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

[0016] The pulling band is a curved structure.

[0029] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model is further explained in detail below in combination with specific implementation manners and with reference to the drawings. It should be noted that the implementation examples and the features in the implementation examples of the utility model can be combined with each other without conflict.

[0030] It is understood that the description is only exemplary and is not intended to limit the scope of the utility model.

[0031] Some embodiments of the utility model are described below in combination with the drawings to provide a kind of.

[0032] With reference to Figures 1-8 A bottle cap with non-rebound flip cover is provided, which comprises a bottle cap composed of flip cover 1 and bottle cap seat 2, the flip cover 1 and bottle cap seat 2 are connected by connecting band 3, the connecting band 3 is provided with at least two creases consisting of crease group, so that the connecting band 3 is formed into at least three section structure, the two sides of the connecting band 3 are provided with pull belt 5, the two ends of the pull belt 5 are connected with the flip cover 1 and bottle cap seat 2 respectively, when the flip cover 1 is opened, the connecting band 3 is folded along the crease group, and the flip cover 1 is fixed by pulling the flip cover 1 through the pull belt 5, which can effectively solve the problem that the connecting band has rebound force and hits the user's face with the flip cover, and greatly increase the opening angle of the flip cover, so that it reaches about 270 ° (such as Figures 6-8 ), which can easily solve the problem that the flip cover directly contacts the user's face when drinking water.

[0033] The crease group is composed of a first crease 41 close to the flip cover 1 and a second crease 42 close to the bottle cap seat 2, and the first crease 41 and the second crease 42 divide the connecting band 3 into an upper band body 31 connected with the flip cover 1, a lower band body 32 connected with the bottle cap seat 2, and a middle band body 33 between the first crease 41 and the second crease 42.

[0034] The first crease 41 and the second crease 42 can be a line groove with a small width, or a groove structure with a relatively large width, and can be a straight line structure or an arc line structure. In addition, the first crease 41 and the second crease 42 can be a groove structure with a larger width, so that the first crease 41 and the second crease 42 are connected to form one crease.

[0035] The connecting band 3 is provided with at least one scratch along the length direction of the crease group, which can be located on the first crease 41 and the second crease 42, that is, directly scratched on the first crease 41 and the second crease 42 (both ends are still connected, if completely scratched, the flip cover 1 and the bottle cap seat 2 will be separated), or located outside the first crease 41 and the second crease 42. When the flip cover 1 is opened, the scratch is cracked (according to the actual structure, the scratch may not be cracked under the condition of meeting the requirements of the flip cover 1, therefore, when the flip cover 1 is opened, the scratch is cracked or not cracked, which belongs to the protection scope), thereby increasing the length of the connecting band 3 that can be extended, further increasing the opening angle of the flip cover 1, better matching the creases with different widths, and achieving a better flip cover effect (for example, the thinner the width of the crease, the smaller the length that can be stretched, and the smaller the opening angle of the flip cover, if the opening angle is too large, it is easy to exceed the limit of the stretchable crease, so that the crease is directly pulled off, if the scratch is matched, even if the width of the crease is thin, the scratch can be cracked during the opening of the flip cover, thereby increasing the limit of the stretchable connecting band, and achieving a better flip cover effect), and at the same time, the difficulty of opening the flip cover 1 is reduced.

[0036] When the lid 1 is opened by an external force to 180 degrees, the connecting band 3 changes from the folded state (i.e. the state when the lid 1 is closed) to the straightened state. Since the pulling band 5 limits the range of movement of the lid 1, in practice the lid 1 is opened to about 150 degrees, at which time the pulling band 5 is in a straightened state, thereby limiting the lid 1 from being opened further backwards. At this time, a greater force needs to be applied to forcibly stretch the pulling band 5, so that the lid 1 can continue to be opened backwards. When the lid 1 is opened to 180 degrees, the pulling band 5 is stretched to the maximum state (when the pulling band 5 is stretched to this state, there is still a margin that can be stretched, and it is within the range of elastic deformation, to avoid the situation that the pulling band 5 cannot be retracted after being stretched). Therefore, the lid 1 is in the range of 150-180 degrees, and since the connecting band 3 is not broken as a whole, the middle part of the connecting band 3 is in a state of relative compression (i.e. the upper band body 31 moves towards the lower band body 32, the lower band body 32 moves towards the upper band body 31, and the middle band body 33 and the first and second creases 41 and 42 change accordingly). The thickness of the upper band body 31 gradually decreases from the lid 1 to the first crease 41, and the thickness of the lower band body 32 gradually decreases from the bottle cap seat 2 to the second crease 42, so that the upper and lower band bodies 31 and 32 can be deformed more easily, thereby making the lid 1 more easily folded to more than 180 degrees.

[0037] When the lid 1 is opened more than 180 degrees, the pulling band 5 retracts, thereby continuing to open the lid 1 backwards until the pulling band 5 retracts to the initial state, at which time it is the normal opening state of the lid 1 (as shown in Figures 5-7 ).

[0038] The thickness of the middle band body 33 gradually increases from the first and second creases 41 and 42 on both sides to the middle, increasing the strength between the middle band bodies 33, to avoid irreversible deformation of the middle band bodies 33 when the lid 1 is in the range of 150-180 degrees, the upper and lower band bodies 31 and 32 are pressed against each other, thereby affecting the opening and closing of the lid 1. For example, when the middle band bodies 33 are pressed, a hump is formed at the middle position, which will cause the distance between the first and second creases 41 and 42 to be shortened, thereby shortening the overall connecting band 3, so that the lid 1 cannot be smoothly closed.

[0039] When the cover 1 is opened, the two sides of the first crease 41 and the second crease 42 are close to each other until they are combined, which is the maximum opening angle of the cover 1. The two sides of the first crease 41 and the second crease 42 can be perpendicular to the bottom of the crease, or form an obtuse angle structure or an acute angle structure with the bottom of the crease. When it is an obtuse angle structure, the distance between the two sides of the crease until they are combined is larger, and the angle of the cover 1 is larger. Conversely, when it is an acute angle structure, the angle of the cover 1 is smaller. The opening angle of the cover 1 can be adjusted according to the actual bottle structure and the use range. For example, for a seasoning bottle, the cover 1 will not hit the user's face, and the opening angle of the cover 1 can be relatively smaller. For a beverage bottle, the opening angle of the cover 1 can be relatively larger. At the same time, the diameter (width) of the bottle body needs to be adjusted appropriately. For example, for a common mineral water bottle on the market, the ratio of the bottle body to the bottle mouth is relatively small. When the cover 1 is opened to about 270°, the cover 1 and the bottle body will not be combined. For example, when the ratio of the bottle body to the bottle mouth is relatively large, that is, the width of the bottle body is large. If the opening angle of the cover 1 is too large, the cover 1 and the upper part of the bottle body will be combined, so it cannot reach the maximum opening angle, and it is easy to bounce back.

[0040] According to different bottle structures, the size of the lower band 32, the upper band 31 and the middle band 33 is adaptively changed. The distance between the first crease 41 and the second crease 42 is specially designed according to the structure of the bottle body.

[0041] The connection between the connection band 3 and the cover 1 is located at any one of the upper end, the middle end and the lower end of the cover 1.

[0042] The middle band 33 can have a uniform thickness, or the thickness of the two ends can be relatively thicker than the middle part, so that the middle band 33 has an arc surface structure.

[0043] The first crease 41 and the second crease 42 are relatively thin positions of the connection band 3.

[0044] Embodiment 1: The pulling band 5 and the connection band 3 are an integral structure, which is simpler in structure.

[0045] Embodiment 2: The pulling band 5 and the connection band 3 are a separate structure, and a gap slot 6 is provided between the pulling band 5 and the connection band 3 to separate them, so as to avoid affecting each other when the cover 1 is opened. For example, when the cover 1 is opened, the pulling band 5 will be forcibly stretched. If the pulling band 5 and the connection band 3 are connected together, the connection band 3 will also be stretched synchronously. At the same time, since the pulling band 5 and the connection band 3 are equivalent to a connection band with a larger width, the range of elastic deformation is reduced, and even the pulling band 5 and the connection band 3 may be directly pulled off.

[0046] As Figures 5-7 The connecting band 3 is connected to the bottle cap seat 2 at any one of the upper end, the middle end and the lower end of the bottle cap seat 2.

[0047] The pulling band 5 is a curved structure, which can be only one curve or a plurality of curves opposite to each other, such as a wave structure; the curved structure can be a left-right direction curve or a front-rear direction curve, and the length of the pulling band 5 is increased by the curved structure, so that the extension length is further increased.

[0048] The connecting band 3 is a curved structure, and the principle of the curved structure of the connecting band 3 is the same as that of the pulling band 5, and the curved structure shape of the connecting band 3 is similar to that of the pulling band 5, so that the consistency of the overall appearance is ensured, and the case that the pulling band 5 is a multi-layer wave structure and the connecting band 3 is a single curved structure is avoided.
