Abstract
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, such as Figure 1 As shown, an external thread structure 21' is provided on the outer side of the bottle mouth 2' of the bottle body 1', and an internal thread structure 31' is provided on the inner side of the cover body 3'. The cover body 3' and the bottle mouth 2' are screwed together by means of the external thread structure 21' and the internal thread structure 31', so as to prevent the contents inside the bottle body 1' from leaking from the bottle mouth. 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 caps are usually made of plastic. Since the thread mating surfaces of glass and plastic materials are relatively smooth, the friction between the internal thread structure of the bottle cap and the external thread structure of the bottle mouth is small, resulting in a small tightening torque. When transporting cosmetic bottles in batches or when users carry cosmetic bottles outside, there is usually vibration during the movement, and the small tightening torque between the bottle mouth and the bottle cap cannot maintain the closure and 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 product is opened and used for the first time, the leakage of contents will cause great loss of the product. In addition, there is also a situation where when there are too many contents inside the cosmetic bottle or thermal expansion occurs, the deformation of the material caused by the high internal pressure of the cosmetic bottle will also cause looseness between the bottle mouth and the bottle cap.
[0003] In addition, there are a large number of technical solutions in the prior art for maintaining the closure and locking between the bottle mouth and the bottle cap, but most of these technical solutions are complex in structure and / or limited by the conventional shapes of the product industry.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0039] like Figure 2 As shown, an embodiment of the utility model provides a closure assembly for a bottle-shaped container, including a bottle mouth 2 of a bottle body 1 and a cover body 3. The bottle mouth 2 is integrally formed on the bottle body 1 and is a columnar structure. The cover body 3 is used to close the bottle mouth 2.
[0040] The bottle mouth 2 and the bottle body are both made of a first 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.
[0041] It should be noted that, taking the bottle-shaped container in the prior art as an example, Figure 1As shown, the cover body 3' made of glass and the bottle mouth 2' made of plastic are screwed together at room temperature by means of an external thread structure 21' and an internal thread structure 31'. When there is vibration, the screw connection structure composed of the external thread structure 21' and the internal thread structure 31' is prone to loosening.
[0042] like Figure 3 and Figure 4 As shown, there is no external thread structure on the outer side of the bottle mouth part 2, and at least one protrusion structure 21 is provided on the outer side of the bottle mouth part 2. In the present embodiment, the protrusion structure 21 is integrally formed on the outer side of the bottle mouth part 2, and the protrusion structure 21 can also be glued on the outer side of the bottle mouth part 2. The protrusion structure 21 can be adapted to the slot structure 31. Specifically, the protrusion structure 21 protrudes outward along the radial direction of the bottle mouth part 2. The shape of the protrusion structure 21 can be cylindrical, prismatic, hemispherical, etc. In the present embodiment, the protrusion structure 21 is cylindrical. The number of the protrusion structures 21 is not limited to 3 as shown in the figure, and can be 1, 2, 4, etc.
[0043] like Figure 5 and Figure 7 As shown, there is no internal thread structure on the inner side surface of the cover body 3, and at least one slot structure 31 is integrally formed on the inner side surface of the cover body 3. The slot structure 31 can be adapted to the protruding structure 21. Specifically, the slot structure 31 is recessed radially outwardly along the cover body 3. The number of the slot structures 31 is not limited to 3 as shown in the figure, and can be 1, 2, 4, etc. When the cover body 3 is covered on the bottle mouth part 2, the cover body 3 and the bottle mouth part 2 can be snap-fitted together with each other by means of the cooperation between the protruding structure 21 and the slot structure 31. Specifically, the protruding structure 21 can enter the slot structure 31 when the cover body 3 is covered on the bottle mouth part 2, and when the cover body 3 can be rotated forwardly relative to the bottle mouth part 2 to make the protruding structure 21 snap-fitted together with the slot structure 31, through the above arrangement, the snap-fitting structure of the utility model can replace the existing screw connection structure. In the case of vibration, the snap-fitting structure is more stable than the screw connection structure, so that the cover body 3 and the bottle mouth part 2 are not easy to loosen, thereby solving the problem that the existing screw connection between the bottle mouth and the bottle cover is easy to loosen.
[0044] Furthermore, if Figure 8 As shown, the slot structure 31 includes a first slot portion 311 and a second slot portion 312. The first slot portion 311 extends vertically or spirally along the axial direction of the cover body 3. In this embodiment, the first slot portion 311 extends vertically, and the second slot portion 312 extends horizontally along the circumference of the cover body 3. Figure 8The first end of the first groove portion 311 penetrates the lower end surface of the cover body 3, so that the protruding structure 21 can pass through the lower end surface of the cover body 3 and enter the first groove portion 311. The second end of the first groove portion 311 is connected to the first end of the second groove portion 312, and the second end of the second groove portion 312 extends in the direction of positive rotation. Figure 8 In other words, the second end of the second groove portion 312 extends toward the left side. Figure 8 A limiting portion 313 is provided at a position near the second end of the second groove portion 312, and the limiting portion 313 is used to limit the protruding structure 21 from escaping from the second groove portion 312. Specifically, the limiting portion 313 is used to be engaged with the protruding structure 21, and the limiting portion 313 is located on the upper side and / or lower side of the second end of the second groove portion 312. In this embodiment, Figure 8 As shown, the limiting portion 313 is located on the lower side of the second end of the second groove portion 312 .
[0045] It should be noted that the cover body 3 is placed in front of the bottle mouth 2, and the protrusion structure 21 needs to be aligned with the slot structure 31. Fig. 9 As shown, during the process of the cover body 3 covering the bottle mouth 2, the protruding structure 21 moves along the axial direction of the cover body 3 and passes through the lower end surface of the cover body 3 into the first groove 311. Fig. 9 In other words, the protruding structure 21 passes through the lower end surface of the cover body 3 in the vertical direction and enters into the first groove portion 311. Fig. 9 As shown, during the positive rotation of the cover body 3 relative to the bottle mouth portion 2, the protruding structure 21 moves along the circumference of the cover body 3 and enters the second groove portion 312. Fig. 9 In other words, the protruding structure 21 moves toward the left side along the lateral direction and enters into the second groove portion 312. Fig.10 As shown, the cover body 3 rotates forward relative to the bottle mouth portion 2 until the protruding structure 21 is engaged with the slot structure 31, that is, the protruding structure 21 moves along the circumference of the cover body 3 in the second slot 312 to the limiting portion 313, and is engaged with the limiting portion 313. Fig.10 In other words, the protruding structure 21 moves toward the left side in the second groove 312 along the transverse direction to the limiting portion 313 , and is engaged with the limiting portion 313 .
