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, including a bottle mouth 1 of a bottle body 3 and a cover body 2. The bottle mouth 1 is integrally formed on the bottle body 3 and is a columnar structure. The cover body 2 is used to close the bottle mouth 1.

[0047] like Figure 2 As shown, a first threaded portion 11 is integrally formed on the outer side of the bottle mouth portion 1, and the number of thread turns of the first threaded portion 11 is 2 to 3. Figure 3 As shown, the first threaded portion 11 is configured with a first thread tooth 111 arranged along the spiral line direction thereof, and the first threaded portion 11 is specifically an external thread structure; Figure 6 As shown, the inner side of the cover body 2 is integrally formed with a second threaded portion 21 adapted to the first threaded portion 11, and the number of thread turns of the second threaded portion 21 is 2 to 3. Figure 8 As shown, the second threaded portion 21 is configured with second thread teeth 211 arranged along the spiral line direction thereof, and the second threaded portion 21 is specifically an internal thread structure; the first threaded portion 11 and the second threaded portion 21 can be adaptively screwed together.

[0048] The bottle mouth 1 is made of a first material, and the cover body 2 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 2 made of the second material are easily loosened by means of the first threaded portion 11 and the second threaded portion 21 at room temperature. Taking this embodiment as an example, the cover 2 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 21. When there is vibration, the screw connection structure formed by the first threaded portion 11 and the second threaded portion 21 is easy to loosen.

[0050] like Figure 2 As shown, the utility model has a first tooth portion 12 integrally formed at the bottle mouth 1, and the first tooth portion 12 is arranged around the outer side of the bottle mouth 1, such as Figure 3 and Figure 4 As shown, the first tooth portion 12 is specifically arranged around the outer side of the bottle mouth portion 1 with the axis of the bottle mouth portion 1 as the center line. The first tooth portion 12 is a continuous or discontinuous tooth ring structure arranged around the outer side of the bottle mouth portion 1. In this embodiment, as shown in FIG. Figure 4 As shown, the first tooth portion 12 is specifically a continuous tooth ring structure arranged around the outer side of the bottle mouth portion 1, and the first tooth portion 12 can be specifically located below the first threaded portion 11. Figure 3 and 4 As shown, the first tooth portion 12 includes a plurality of first teeth 121 arranged around and arranged along the outer side of the bottle mouth portion 1, and the number of the first teeth 121 is 20 to 30. The first teeth 121 can be in the shape of a triangle, rectangle, trapezoid, arc, sawtooth, etc.

[0051] like Figure 6 and 7 As shown, a second tooth portion 22 capable of matching with the first tooth portion 12 is integrally formed on the inner side surface of the cover body 2, and the second tooth portion 22 is arranged on the second thread 211, and the second tooth portion 22 is located at the lower end of the second thread portion 21; it should be noted that the lower end of the second thread portion 21 is understood to be the end of the second thread portion 21 close to the bottom opening of the cover body 2; as shown in FIG. Figure 8 As shown, the second tooth portion 22 includes a plurality of second teeth 221 arranged along the spiral line direction of the second thread portion, the number of the second teeth 221 is 20 to 30, and the second teeth 221 can be in the shape of a triangle, a rectangle, a trapezoid, an arc, a sawtooth, etc. The first tooth portion 12 and the second tooth portion 22 can be adaptively engaged.

[0052] The utility model provides the first tooth portion 12 and the second tooth portion 22, and when the cover body 2 and the bottle mouth 1 are tightened, the first threaded portion 11 and the second threaded portion 21 are screwed together, and the first tooth portion 12 and the second tooth portion 22 are meshed together, so that a shape-matched locking connection is additionally established between the bottle mouth 1 and the cover body 2, so that the first tooth portion 12 and the second tooth portion 22 in the meshed state can prevent the cover body 2 from rotating relative to the bottle mouth 1 along the circumferential direction, thereby solving the problem that the bottle mouth 1 and the cover body 2 are prone to loosening when they are only screwed together. In addition, since the structure that can achieve self-locking is relatively simple in itself and can be integrally formed with the bottle body 3 and the cover body 2, especially for small-capacity cosmetic bottles that have been finalized on the market for a long time, especially nail polish bottles or nail polish glue bottles, the technical solution of the utility model does not or almost does not cause additional process and material costs.

[0053] It should be noted that when the cover body 2 needs to be separated from the bottle mouth portion 1 in the tightened state, a large torque needs to be applied to the cover body 2 to force the first tooth portion 12 and the second tooth portion 22 to separate, so that the first tooth portion 12 and the second tooth portion 22 no longer hinder the cover body 2 from rotating relative to the bottle mouth portion 1 in the circumferential direction. Moreover, compared with the material of the cover body 2, the bottle mouth portion 1 is made of a material with a higher hardness. After the cover body 2 is separated from the bottle mouth portion 1 for the first time (i.e., after the first unsealing), the cover body 2 and the bottle mouth portion 1 are tightened and separated for many times, and the second tooth portion 22 on the cover body 2 will gradually be worn by the first tooth portion 12. The worn second tooth portion 22 is difficult or impossible to mesh with the first tooth portion 12, so that the cover body 2 no longer needs a large torque to separate or tighten, so that the user can smoothly unscrew and tighten the cover body 2, and improve the user's experience of subsequently unscrewing and tightening the cover body 2.

[0054] In some specific embodiments, Figures 2 to 4 As shown, a matching boss 13 is integrally formed on the outer side of the bottle mouth portion 1. The matching boss 13 is arranged around the outer side of the bottle mouth portion 1. The matching boss 13 is specifically a continuous or discontinuous annular structure, such as Figure 5 As shown, the mating boss 13 has a boss outer peripheral surface 131, a boss upper side surface 132 and a boss lower side surface (not shown), the boss upper side surface 132 is arranged opposite to the boss lower side surface, the boss outer peripheral surface 131 faces the radial outer side of the bottle mouth 1, the first tooth portion 12 is arranged on the mating boss 13, according to the position and structure of the second tooth portion 22, as shown Figure 5 The first tooth portion 12 can be disposed on the boss outer peripheral surface 131 and / or the boss upper side surface 132. It should be noted that the boss outer peripheral surface 131 is the outer peripheral surface of the mating boss 13, the boss upper side surface 132 is the upper side surface of the mating boss 13, and the boss lower side surface is the lower side surface of the mating boss 13.

[0055] In some specific embodiments, according to the position and structure of the first tooth portion 12, such as Fig. 9 As shown, the second tooth portion 22 can be arranged at the tooth top 2111 and / or the second tooth lower side surface 2112 of the second thread tooth 211. It should be noted that the second tooth upper side surface is the upper side surface of the second thread tooth 211, and the second tooth lower side surface 2112 is the lower side surface of the second thread tooth 211. Fig. 9 As shown, the second thread tooth 211 has a second tooth upper side surface (not marked) and a second tooth lower side surface 2112. The connection between the second tooth upper side surface and the second tooth lower side surface 2112 constitutes a tooth top 2111, and the tooth top 2111 faces the radial inner side of the cover body 2.

[0056] In this embodiment, the first tooth portion 12 and the second tooth portion 22 are specifically arranged at: Figures 2 to 5 As shown, the first tooth portion 12 is disposed on the outer peripheral surface 131 of the mating boss 13, as shown in FIG. Figures 6 to 9 As shown, the second tooth portion 22 can be arranged at the tooth top 2111 of the second thread tooth 211. Correspondingly, the arrangement positions of the first tooth portion 12 and the second tooth portion 22 can also be: the first tooth portion 12 is arranged at the boss upper side 132 of the mating boss 13, and the second tooth portion 22 is arranged at the second tooth lower side 2112 of the second thread tooth 211.

[0057] In some specific embodiments, at least two first tooth portions 12 are arranged at intervals along the axial direction of the bottle mouth portion 1, such as Fig.10 As shown in the orientation, the axial direction of the bottle mouth portion 1 is the vertical direction. Specifically, Fig.10 As shown, both of the two first tooth portions 12 can mesh with the second tooth portion 22 , which further improves the stability of the latching connection compared to the method in which only one first tooth portion 12 meshes with the second tooth portion 22 .

[0058] The bottle body 3 of the present invention can be a cosmetic bottle, and can further be a nail polish bottle, a nail polish glue bottle, a perfume bottle, an essence bottle or a lotion bottle, and can especially be a nail polish bottle or a nail polish glue bottle.
