Description

Technical Field

[0001] The utility model relates to a container with a closing component, in particular to a bottle-shaped container and a closing component used for the bottle-shaped container. Background Art

[0002] In existing bottle-shaped containers, the mouth of the bottle body is usually closed by screwing the bottle cap to prevent the contents inside the bottle body from leaking from the mouth of the bottle. Especially in the field of cosmetics, most cosmetic bottles, such as nail polish bottles, nail polish bottles, perfume bottles, essence bottles, lotion bottles, etc., are usually made of glass, and the bottle cap is usually made of plastic. Since the threaded mating surfaces of glass and plastic materials are relatively smooth, the friction between the thread of the bottle cap and the thread of the bottle mouth is small, resulting in a small tightening torque. When the cosmetic bottles are transported in batches or when users carry the cosmetic bottles for movement, there is usually vibration during the movement, and the small tightening torque between the bottle mouth and the bottle cap cannot maintain the closed locking of the bottle cap and the bottle mouth, resulting in looseness between the bottle mouth and the bottle cap, which in turn causes the contents inside the cosmetic bottle to leak from the bottle mouth. Especially before the filled and sealed goods are opened and used for the first time, the leakage of the contents will cause great loss of the product. In addition, there is a situation where, when there are too many contents inside the cosmetic bottle or thermal expansion occurs, the material deformation caused by the high internal pressure of the cosmetic bottle may also cause looseness between the bottle mouth and the bottle cap.

[0046] like Figure 1 As shown, an embodiment of the utility model provides a closure assembly for a bottle-shaped container, comprising a bottle mouth portion 1 of a bottle body, a bottle body portion 2 of the bottle body and a cover body 3, wherein the bottle mouth portion 1 is integrally formed on the bottle body, the bottle body portion 2 is integrally formed on the bottle body, the bottle mouth portion 1 is a columnar structure, the bottle mouth portion 1 is arranged on the top surface of the bottle body portion 2, and the cover body 3 is used to close the bottle mouth portion 1.

[0047] like Figure 2 As shown, a first threaded portion 11 is integrally formed on the outer surface of the bottle mouth portion 1, the number of thread turns of the first threaded portion 11 is 2 to 3, and the first threaded portion 11 is specifically an external thread structure; Figure 6 As shown, the inner side surface of the cover body 3 is integrally formed with a second threaded portion 31 that can be adapted to the first threaded portion 11, the number of thread turns of the second threaded portion 31 is 2 to 3, the second threaded portion 31 is specifically an internal thread structure, the first threaded portion 11 and the second threaded portion 31 can be adapted to be screwed together, specifically, the cover body 3 is rotated forward relative to the bottle mouth portion 1 to screw the first threaded portion 11 and the second threaded portion 31 together, so that they are tightened together; the cover body 3 is rotated reversely relative to the bottle mouth portion 1 to separate the first threaded portion 11 and the second threaded portion 31, so that they are loosened from each other. It should be noted that the forward rotation refers to the movement of the cover body 3 during the tightening process on the bottle mouth portion 1, and the reverse rotation refers to the movement of the cover body 3 during the loosening process on the bottle mouth portion 1.

[0048] The bottle mouth 1 and the bottle body 2 are both made of a first material, and the cover 3 is made of a second material. Specifically, the first material can be a material with a certain hardness such as glass, metal or ceramic, preferably a material with a harderness greater than that of the second material. Corresponding to the first material, the second material can be a flexible material with moderate elasticity such as plastic or composite material.

[0049] It should be noted that the bottle mouth 1 made of the first material and the cover 3 made of the second material are easily loosened by means of the first threaded portion 11 and the second threaded portion 31 at room temperature. Taking this embodiment as an example, the cover 3 made of glass and the bottle mouth 1 made of plastic are screwed together by means of the first threaded portion 11 and the second threaded portion 31. When there is vibration, the screw connection structure formed by the first threaded portion 11 and the second threaded portion 31 is easy to loosen.

[0050] like Figure 2 and Figure 3 As shown, a first tooth portion 21 is integrally formed on the top surface of the bottle body 2, and the first tooth portion 21 is arranged around the outer side of the bottle mouth 1, as shown in FIG. Figure 4 and Figure 5 As shown, the first tooth portion 21 is specifically arranged on the top surface of the bottle body 2 and around the outer side of the bottle mouth 1 with the axis of the bottle mouth 1 as the center line. The first tooth portion 21 is arranged continuously or discontinuously around the outer side of the bottle mouth 1. In this embodiment, as shown in FIG. Figure 4 and 5 As shown, the first tooth portion 21 is continuously arranged around the top surface of the bottle body 2 and is located outside the bottle mouth 1. Figures 3 to 5 As shown, the first tooth portion 21 includes a plurality of first teeth 211 arranged in a surrounding manner, the number of the first teeth 211 is 20 to 30, and the first teeth 211 can be in a triangular shape, a sawtooth shape, etc., especially a sawtooth shape.

[0051] like Figure 6 and Figure 7 As shown, the lower end surface of the cover body 3 is integrally formed with a second tooth portion 32 that can be adapted to the first tooth portion 21, and the second tooth portion 32 is arranged around the lower end surface of the cover body 3, as shown in FIG. Figure 8 and Fig. 9 As shown, the second tooth portion 32 is specifically arranged around the lower end surface of the cover body 3 with the axis of the cover body 3 as the center line. The second tooth portion 32 is arranged around the lower end surface of the cover body 3 continuously or discontinuously. In this embodiment, as shown in FIG. Figure 8 and Fig. 9 As shown, the second tooth portion 32 is continuously arranged around the lower end surface of the cover body 3. Figures 7 to 9As shown, the second tooth portion 32 includes a plurality of second teeth 321 arranged in a surrounding manner, the number of the second teeth 321 is 20 to 30, and the second teeth 321 can be in a triangular shape, a sawtooth shape, etc., especially a sawtooth shape, and the first tooth portion 21 and the second tooth portion 32 can be adaptively meshed. When the cover body 3 and the bottle mouth portion 1 are tightened, the first threaded portion 11 and the second threaded portion 31 are screwed together, and the first tooth portion 21 and the second tooth portion 32 are meshed to prevent the cover body 3 from rotating in the opposite direction relative to the bottle mouth portion 1.

[0052] The utility model sets the first tooth portion 21 and the second tooth portion 32. When the cover body 3 of the utility model is rotated forwardly relative to the bottle mouth portion 1 to reach a tightened state, the first threaded portion 11 is screwed with the second threaded portion 31, and the first tooth portion 21 is meshed with the second tooth portion 32. The meshed first tooth portion 21 and the second tooth portion 32 can prevent the cover body 3 from rotating in the opposite direction relative to the bottle mouth portion 1, thereby solving the problem that the cover body 3 is prone to loosening.

[0053] It should be noted that when the cover body 3 needs to be separated from the bottle mouth portion 1 in the tightened state, a large reverse torque needs to be applied to the cover body 3 to force the first tooth portion 21 and the second tooth portion 32 to separate, so that the first tooth portion 21 and the second tooth portion 32 no longer hinder the reverse rotation of the cover body 3 relative to the bottle mouth portion 1. Moreover, compared with the material of the cover body 3, the bottle body 2 is made of a material with a higher hardness. After the cover body 3 is separated from the bottle mouth portion 1 for the first time (i.e., after the first unsealing), the cover body 3 undergoes multiple forward and reverse rotations, and the second tooth portion 32 on the cover body 3 will gradually be worn by the first tooth portion 21. The worn second tooth portion 32 is difficult or impossible to mesh with the first tooth portion 21, so that the cover body 3 no longer requires a large torque to separate, so that the user can smoothly unscrew the cover body 3, thereby improving the user's experience of unscrewing the cover body 3 later.

[0054] Furthermore, if Fig.10 As shown, the first tooth 211 has an upward first inclined surface 2111 and a first end surface 2112 facing the circumferential direction. The upward first inclined surface 2111 refers to the first inclined surface 2111 facing the circumferential direction. Figure 1 The first end face 2112 facing the circumferential direction refers to the first end face 2112 facing the circumferential direction of the bottle mouth 1. The inclination direction of the first inclined surface 2111 is opposite to the inclination direction of the first threaded portion 11 and the second threaded portion 31. The second tooth 321 is a flexible tooth. The second tooth 321 has a second end face 3212 that can be adapted to the first end face 2112. In the tightened state, the second tooth 321 is engaged with the first tooth 211 through flexible deformation, so that the second end face 3212 can be against the first end face 2112 during reverse rotation. Continue to refer to Fig.10Further explanation, when the cover body 3 rotates forward relative to the bottle mouth 1, Fig.10 The cover 3 in the middle will drive the second tooth part 32 to move to the left. Since the second tooth 321 is a flexible tooth, it can be flexibly deformed and will not hinder the movement of the cover 3. Therefore, the cover 3 can complete the positive rotation under the appropriate positive torque to achieve the tightening state. Fig.10 Further, when the cover 3 and the bottle mouth 1 are tightened, a reverse torque is applied to the cover 3. Fig.10 The cover body 3 will drive the second tooth portion 32 to move rightward until the first end face 2112 and the second end face 3212 abut against each other. At this time, the first end face 2112 and the second end face 3212 abutting against each other will prevent the second tooth 321 from continuing to move rightward, so that the cover body 3 cannot rotate in the opposite direction relative to the bottle mouth part 1, and finally solves the problem that the cover body 3 is prone to loosening.

[0055] In some specific embodiments, Fig.10 As shown, the second tooth 321 also has a second inclined surface 3211 facing downwards. The second inclined surface 3211 facing downwards refers to the second inclined surface 3211 facing the Figure 1 The second end surface 3212 is recessed inwardly at the intersection with the second inclined surface 3211 to form a groove 3213, and the groove 3213 makes the second tooth 321 cantilevered and elastic. Fig.10 Further explanation, when the cover body 3 rotates forwardly relative to the bottle mouth 1, Fig.10 The cover body 3 in the middle will drive the second tooth part 32 to move leftward. Since the second tooth 321 is elastic and can be elastically deformed, it will not hinder the movement of the cover body 3. Therefore, the cover body 3 can complete the positive rotation under the appropriate positive torque to achieve the tightening state. That is to say, the utility model improves the deformation ability of the second tooth 321 by arranging the groove 3213 on the second tooth 321, thereby improving the smoothness of the cover body 3 when it rotates forward relative to the bottle mouth part 1. Fig.10 Further explanation, since the second teeth 321 with the groove 3213 structure has a certain elastic deformation ability, when the cover body 3 and the bottle mouth part 1 are tightened, the second inclined surface 3211 will exert a downward rebound force on the first inclined surface 2111, so that a part of the second inclined surface 3211 fits on the first inclined surface 2111, thereby improving the meshing stability of the first teeth 211 and the second teeth 321, which is conducive to solving the problem that the cover body 3 is easy to loosen. In addition, since the second teeth 321 have grooves 3213, the strength of the second teeth 321 is reduced, making the second teeth 321 more easily damaged, thereby reducing the difficulty of the first teeth 211 wearing the second teeth 321; that is, after the cover body 3 and the bottle mouth part 1 are separated for the first time (i.e., after the first unsealing), the second teeth part 32 is more likely to be worn, further improving the user's experience of subsequently unscrewing the cover body 3.
