DETAILED DESCRIPTION

[0026] The embodiments of the present application will be described in further detail to which reference is made to the accompanying drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0027] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "axial direction", "radial direction", and "circumferential direction" are the axial direction, the radial direction, and the circumferential direction of the cosmetic container and the glass bottle, respectively. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0028] In the description of the embodiments of the present application, it should be noted that the terms "left", "right", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", "third", and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "communication" and "connection" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral connection; can be mechanical connection, can also be electrical connection; can be direct connection, or indirect connection through intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0030] The container for holding and storing cosmetics can be of glass material, such as a glass bottle. In the related art, the glass bottle is usually made by a blowing process, and some glass bottles are formed with a limiting structure for clamping the bottle cap. The limiting structure is usually arranged on the bottle shoulder, and the bottle shoulder is usually formed by extrusion molding by the gas pressure of the external mold and the internal blowing needle. The extrusion molding pressure provided by the gas pressure is limited, resulting in low forming precision and low position precision of the limiting structure on the bottle shoulder, increasing the manufacturing difficulty and reducing the product yield.

[0031] Based on the above situation, the first aspect of the embodiments of the present application provides a cosmetic container 10. Please refer to Figures 1 to 6 The cosmetic container 10 includes a glass bottle 11 and a bottle cap 12. The glass bottle 11 is configured to be made by a blowing process. The glass bottle 11 includes a bottle body 111, a bottle neck 112, and a bottle shoulder 113 for transitionally connecting the bottle body 111 and the bottle neck 112. The bottle neck 112 includes a threaded segment 112a and a limiting segment 112b connected to each other. A part of the limiting segment 112b protrudes outward along the radial direction of the glass bottle 11 to form at least one first limiting protrusion 112d. The bottle cap 12 is provided with at least one limiting part. The bottle cap 12 has a locked state and an unlocked state. The bottle cap 12 can rotate relative to the glass bottle 11 under the action of external force to switch between the locked state and the unlocked state. In the locked state, the threaded segment 112a is threadedly matched with the bottle cap 12, and the first limiting protrusion 112d is rotationally matched with the limiting part.

[0032] It should be noted that the glass bottle 11 also includes a bottle mouth 114 located at the top of the glass bottle 11 along the height direction, and a bottle bottom 115 located at the bottom of the glass bottle 11 along the height direction.

[0033] Exemplarily, the cosmetic container 10 further includes a sealing member 13 arranged at least at the bottle mouth 114, for forming a seal between the glass bottle 11 and the bottle cap 12 when the bottle cap 12 is tightened with the glass bottle 11, to prevent the cosmetics in the glass bottle 11 from leaking.

[0034] The glass bottle 11 in the present application needs to use a blowing device in the process of being made by a blowing process. The blowing device includes a blowing needle and an open-close mold. The open-close mold can be at least divided into two parts to realize mold opening and mold closing. The blowing needle can output airflow with a certain pressure from a blowing hole. In the process of manufacturing the glass bottle 11 by the blowing process, the glass is in a liquid state. The liquid glass is wrapped around one end of the air outlet of the blowing needle, the open-close mold is sleeved outside the liquid glass, and the mold is closed. In the process of closing the mold, the inner wall of the open-close mold is used to shape the outer surface of the glass bottle 11. At the same time, the blowing needle has a smooth outer surface. The inner wall of the open-close mold and the outer surface of the blowing needle extrude the liquid glass to form the neck 112 and the mouth 114 of the glass bottle 11. The pressure of the gas output by the blowing needle drives the part of the liquid glass from the inside of the liquid glass below the neck 112 outward to adhere to the inner wall of the open-close mold, thereby forming the shoulder 113, the body 111 and the bottom 115 of the glass bottle 11. It can be understood that the neck 112 and the mouth 114 are formed by extrusion between the inner wall of the open-close mold and the outer surface of the blowing needle, and the forming force is large. The shoulder 113, the body 111 and the bottom 115 are formed by the action of the blowing needle output gas pressure and the inner wall of the open-close mold, and the forming force is smaller.

[0035] The neck 112 includes a threaded segment 112a and a limiting segment 112b connected to each other, wherein the threaded segment 112a is used to threadedly cooperate with the bottle cap 12 and limit the bottle cap 12 in the axial direction. Part of the limiting segment 112b protrudes outward along the radial direction of the glass bottle 11 to form at least one first limiting protrusion 112d, which limits the bottle cap 12 in the rotation direction through the first limiting protrusion 112d.

[0036] The first limiting protrusion 112d is arranged on the limiting segment 112b of the neck 112, that is, by arranging the first limiting protrusion 112d close to the threaded segment 112a, so that in the process of forming the glass bottle 11, the first limiting protrusion 112d can be extruded by the outer mold and the outer surface of the inner blowing needle, which can increase the extrusion force and improve the stability of the first limiting protrusion 112d, thereby improving the position accuracy of the first limiting protrusion 112d and improving the situation that the first limiting protrusion 112d is arranged on the shoulder 113 and the forming force of the first limiting protrusion 112d is small and the stability is low.

[0037] The number of the first limiting protrusions 112d can be one or more, which is not limited here.

[0038] The number of the limiting parts can be one or more, which is not limited here.

[0039] The plurality in the embodiment of the present application means the case of two or more.

[0040] The number of the limiting portions can be the same as the number of the first limiting protrusions 112d, and one-to-one correspondence.

[0041] The bottle cap 12 has a locked state and an unlocked state. In the locked state, the threaded segment 112a is threadedly engaged with the bottle cap 12, and the first limiting protrusion 112d is rotationally engaged with the limiting portion, thereby achieving fixation of the bottle cap 12. Under the action of an external force in the counterclockwise direction, the bottle cap 12 rotates relative to the glass bottle 11 in the counterclockwise direction, so that the first limiting protrusion 112d is separated from the limiting portion, and the bottle cap 12 switches from the locked state to the unlocked state. At this time, the bottle cap 12 is unscrewed, and the cosmetic in the glass bottle 11 can be used.

[0042] It should be noted that, in this application, the counterclockwise direction and the clockwise direction are the directions of rotation when observing from the bottle mouth 114 to the bottle bottom 115 along the axial direction of the glass bottle 11.

[0043] The cosmetic container 10 provided by the embodiments of the present application achieves fixation of the bottle cap 12 by rotationally engaging the first limiting protrusion 112d of the glass bottle 11 with the limiting portion on the bottle cap 12. At the same time, the first limiting protrusion 112d is arranged on the limiting segment 112b of the bottle neck 112, that is, the first limiting protrusion 112d is arranged close to the threaded segment 112a. In this way, during the molding process of the glass bottle 11, the first limiting protrusion 112d can be extruded by the outer surface of the external mold and the internal blow needle together, which can increase the extrusion force and improve the stability of the molding of the first limiting protrusion 112d, thereby improving the positional accuracy of the first limiting protrusion 112d.

[0044] In some embodiments, referring to Figure 3 The bottle neck 112 includes a transition segment 112c. The limiting segment 112b is connected to the transition segment 112c at an end away from the threaded segment 112a along the axial direction of the glass bottle 11. The transition segment 112c is connected to the bottle shoulder 113 at an end away from the limiting segment 112b along the axial direction.

[0045] The transition segment 112c is arranged on the bottle neck 112, so that the limiting segment 112b and the bottle shoulder 113 are separated by the transition segment 112c. In this way, the first limiting protrusion 112d on the limiting segment 112b is not adjacent to the bottle shoulder 113, so that the first limiting protrusion 112d is away from the bottle shoulder 113 formed by the blow needle, and the first limiting protrusion 112d is extruded by the blow needle and the external mold, which improves the stability of the molding of the first limiting protrusion 112d, thereby improving the positional accuracy.

[0046] In some embodiments, referring to Figures 4 to 6The limiting portion includes a second limiting protrusion 1211 and a third limiting protrusion 1212 protruding along the axial direction of the glass bottle 11 respectively. The second limiting protrusion 1211 and the third limiting protrusion 1212 define a limiting slot 121a therebetween. In the locked state, the first limiting protrusion 112d cooperates with the limiting slot 121a.

[0047] The limiting portion includes a second limiting protrusion 1211 and a third limiting protrusion 1212 protruding along the axial direction of the glass bottle 11 respectively, that is, the second limiting protrusion 1211 and the third limiting protrusion 1212 define a slot opening of the limiting slot 121a facing the bottle bottom 115 along the axial direction. Thus, when the bottle cap 12 is screwed clockwise on the glass bottle 11, the first limiting protrusion 112d is facilitated to enter the limiting slot 121a along the axial and rotational directions and cooperate with the limiting slot 121a. Of course, the first limiting protrusion 112d is also facilitated to be disengaged from the limiting slot 121a.

[0048] In some embodiments, referring to Figures 4 to 6 The third limiting protrusion 1212 has a dimension along the axial direction of the glass bottle 11 greater than that of the second limiting protrusion 1211 along the axial direction of the glass bottle 11. The second limiting protrusion 1211 guides the first limiting protrusion 112d to enter or disengage from the limiting slot 121a.

[0049] The third limiting protrusion 1212 has a dimension along the axial direction of the glass bottle 11 greater than that of the second limiting protrusion 1211 along the axial direction of the glass bottle 11. It can be understood that the greater the dimension of the second limiting protrusion 1211 or the third limiting protrusion 1212 along the axial direction of the glass bottle 11, the greater the blocking force on the first limiting protrusion 112d.

[0050] The second limiting protrusion 1211 guides the first limiting protrusion 112d to enter or disengage from the limiting slot 121a, that is, the first limiting protrusion 112d enters or disengages from the limiting slot 121a from the second limiting protrusion 1211 having a smaller dimension along the axial direction of the glass bottle 11, and the second limiting protrusion 1211 has a smaller blocking force on the first limiting protrusion 112d, so that the user can save more labor when driving the bottle cap 12 to lock or unlock on the glass bottle 11, and the use experience can be improved.

[0051] It should be noted that in the process of guiding the first limiting protrusion 112d to enter or disengage from the limiting slot 121a by the second limiting protrusion 1211, the bottle cap 12 where the second limiting protrusion 1211 is located can be elastically deformed, the glass bottle 11 where the first limiting protrusion 112d is located can be elastically deformed, or both the bottle cap 12 where the first limiting protrusion 112d is located and the glass bottle 11 where the second limiting protrusion 1211 is located can be elastically deformed, so that the first limiting protrusion 112d enters or disengages from the limiting slot 121a, which is not limited herein.

[0052] The second limiting protrusion 1211 is elastically deformed to allow the first limiting protrusion 112d to enter or exit the limiting groove 121a.

[0053] It can be understood that in the locked state, the third limiting protrusion 1212 can provide greater blocking force for the first limiting protrusion 112d to prevent the bottle cap 12 from continuing to rotate clockwise and tighten.

[0054] In some embodiments, referring to Figures 4 to 6 , the side of the second limiting protrusion 1211 facing the bottle shoulder 113 has a first guide surface 1211a. The first guide surface 1211a is used to guide the first limiting protrusion 112d to be clamped into the limiting groove 121a.

[0055] It should be noted that the first guide surface 1211a is located on the side of the second limiting protrusion 1211 away from the limiting groove 121a.

[0056] That is, in the process of switching from the unlocked state to the locked state, the user drives the first guide surface 1211a on the bottle cap 12 to contact the first limiting protrusion 112d, and the first limiting protrusion 112d exerts a reverse force on the first guide surface 1211a, thereby causing the bottle cap 12 where the first guide surface 1211a is located to elastically deform. The arrangement of the first guide surface 1211a can reduce the force required for locking, making the operation of locking the bottle cap 12 more simple and labor-saving.

[0057] In some embodiments, referring to Figures 4 to 6 , the side of the second limiting protrusion 1211 facing the bottle shoulder 113 has a second guide surface 1211b. The second guide surface 1211b is used to guide the first limiting protrusion 112d to exit the limiting groove 121a.

[0058] Here, the second guide surface 1211b is located on the side of the second limiting protrusion 1211 close to the limiting groove 121a, that is, the groove wall of the limiting groove 121a. In the process of switching from the locked state to the unlocked state, the second guide surface 1211b on the bottle cap 12 contacts the first limiting protrusion 112d, which is also conducive to driving the bottle cap 12 where the second guide surface 1211b is located to elastically deform, reducing the force required to unlock the bottle cap 12.

[0059] In some embodiments, referring to Figures 4 to 6 , the distance between the first guide surface 1211a and the bottom 115 of the glass bottle 11 gradually decreases in the rotation direction of the bottle cap 12.

[0060] It should be noted that the bottom 115 of the glass bottle 11 is generally planar, and the plane where the bottom 115 is located is perpendicular to the axial direction of the glass bottle 11.

[0061] In addition, the rotation direction herein refers to the counterclockwise direction observed from the top to the bottom of the bottle cap 12, that is, the rotation direction when the bottle cap 12 is unlocked, and in the drawings, the direction from left to right. Figure 6

[0062] As shown in Figure 6 , along the rotation direction of the bottle cap 12, the first guide surface 1211a gradually approaches the bottle bottom 115, so that the distance between the first guide surface 1211a and the bottle bottom 115 of the glass bottle 11 gradually decreases, and the first guide surface 1211a has a certain slope.

[0063] During the process of switching from the unlocked state to the locked state of the bottle cap 12 relative to the glass bottle 11 in the direction of the glass bottle 11, the first guide surface 1211a gradually approaches the bottle bottom 115 and has a certain slope, which can make the first guide surface 1211a on the bottle cap 12 gradually increase the reaction force from the first limiting protrusion 112d, increase the sliding friction, and further make the user feel a certain resistance when driving the bottle cap 12 to rotate to the locked position, so as to prompt the user and improve the user's experience; on the contrary, during the process of switching from the locked state to the unlocked state of the bottle cap 12, when the first limiting protrusion 112d passes through the second guide surface 1211b and contacts the first guide surface 1211a, the slope of the first guide surface 1211a can provide support force to the first limiting protrusion 112d, guiding the first limiting protrusion 112d to move away from the limiting groove 121a.

[0064] It should be noted that the first guide surface 1211a can be a plane, a curved surface, or a combination of the two, which is not limited here.

[0065] Exemplarily, the first guide surface 1211a is a plane, and the first guide surface 1211a and the first limiting protrusion 112d are in line contact, so as to reduce the contact area between the first guide surface 1211a and the first limiting protrusion 112d, and facilitate the relative sliding between the two.

[0066] In some embodiments, referring to Figures 4 to 6 , along the rotation direction of the bottle cap 12, the distance between the second guide surface 1211b and the bottle bottom 115 of the glass bottle 11 gradually increases.

[0067] Similarly, the rotation direction of the bottle cap 12 herein refers to the counterclockwise direction observed from the top to the bottom of the bottle cap 12, that is, the rotation direction when the bottle cap 12 is unlocked, and in the drawings, the direction from left to right. Figure 6

[0068] As shown in Figure 6 ​​As shown, the second guide surface 1211b gradually moves away from the bottle bottom 115 in the rotation direction of the bottle cap 12, so that the distance between the second guide surface 1211b and the bottle bottom 115 of the glass bottle 11 gradually increases, and the second guide surface 1211b has a certain slope.

[0069] Thus, in the locked state, the slope of the second guide surface 1211b causes the reaction force on the second guide surface 1211b of the bottle cap 12 to gradually increase during the process of switching from the locked state to the unlocked state, which can improve the situation that the first limiting protrusion 112d is easily out of the limiting groove 121a due to accidental touch; on the contrary, during the process of switching from the unlocked state to the locked state, when the first limiting protrusion 112d passes the first guide surface 1211a, the first limiting protrusion 112d contacts the second guide surface 1211b, and the slope of the second guide surface 1211b can guide the first limiting protrusion 112d to quickly enter the limiting groove 121a, completing the cooperation between the first limiting protrusion 112d and the limiting groove 121a.

[0070] In some embodiments, the distance between the first guide surface 1211a and the bottle bottom 115 of the glass bottle 11 gradually decreases in the circumferential direction of the bottle cap 12, and the distance between the second guide surface 1211b and the bottle bottom 115 of the glass bottle 11 gradually increases. That is, the thickness of the second limiting protrusion 1211 gradually decreases from the middle to the two ends in the circumferential direction, and the thickest position in the middle divides the second limiting protrusion 1211 into the first guide surface 1211a and the second guide surface 1211b. In this way, the first guide surface 1211a and the second guide surface 1211b both have a certain slope, and when the first limiting protrusion 112d contacts the first guide surface 1211a and the second guide surface 1211b, one part of the force applied by the user in the rotation direction drives the bottle cap 12 to elastically deform in the axial direction through the slope, and the other part is used to overcome the frictional resistance between the first limiting protrusion 112d and the second limiting protrusion 1211, which can improve the stress structure of the second limiting protrusion 1211, and at the same time, the slope makes the process of the first limiting protrusion 112d entering and out of the limiting groove 121a more smooth.

[0071] In some embodiments, the size of the first guide surface 1211a in the rotation direction is greater than the size of the second guide surface 1211b in the rotation direction.

[0072] Since the first guide surface 1211a and the second guide surface 1211b have the same size in the axial direction, the size of the first guide surface 1211a in the rotating direction is greater than the size of the second guide surface 1211b in the rotating direction, so that the inclination degree of the first guide surface 1211a is less than the inclination degree of the second guide surface 1211b, and the second guide surface 1211b is steeper relative to the first guide surface 1211a. On the one hand, the inclination degree of the first guide surface 1211a is more gentle, so that the force of the user driving the bottle cap is more distributed in the axial direction, the first limiting protrusion 112d has a greater force on the bottle cap 12 in the axial direction, and the bottle cap 12 is more easily elastically deformed, so that the first limiting protrusion 112d is more easily entered into the limiting groove 121a, thereby reducing the external force required when switching to the locked state. On the other hand, the second guide surface 1211b is steeper, and the force of the user driving the bottle cap is less distributed in the axial direction, and a greater external force is required to drive the bottle cap 12 to elastically deform in the axial direction. The locking force of the second guide surface 1211b on the first limiting protrusion 112d is greater, and the first limiting protrusion 112d is less likely to come out of the limiting groove 121a, thereby improving the locking reliability of the bottle cap 12.

[0073] In some embodiments, referring to Figures 4 to 6 , the first limiting protrusion 112d has a first rotation-stopping surface 112e parallel to the axial direction on one side in the circumferential direction. The third limiting protrusion 1212 has a second rotation-stopping surface 1212a parallel to the axial direction. The second rotation-stopping surface 1212a is formed as part of the groove wall of the limiting groove 121a and is in contact with the first rotation-stopping surface 112e in the locked state to block the first limiting protrusion 112d from continuing to rotate.

[0074] The first rotation-stopping surface 112e and the second rotation-stopping surface 1212a are both parallel to the axial direction, which means that the plane on which the first rotation-stopping surface 112e is located is substantially parallel or completely parallel to the axial direction, and the plane on which the second rotation-stopping surface 1212a is located is substantially parallel or completely parallel to the axial direction.

[0075] In the locked state, the second rotation-stopping surface 1212a is in contact with the first rotation-stopping surface 112e, which can be line contact or surface contact, etc., which is not limited here.

[0076] The first rotation-stopping surface 112e and the second rotation-stopping surface 1212a are both parallel to the axial direction, so that the first rotation-stopping surface 112e and the second rotation-stopping surface 1212a are both perpendicular to the rotating direction of the bottle cap 12, that is, perpendicular to the circumferential direction of the glass bottle 11. In this way, the second rotation-stopping surface 1212a can improve the blocking force of the second rotation-stopping surface 1212a on the first limiting protrusion 112d by being in contact with the first rotation-stopping surface 112e.

[0077] In some embodiments, referring to Figures 1 to 6The bottle cap 12 comprises an inner cap 121 and an outer cap 122 sleeved on the inner cap 121. The outer cap 122 extends axially towards the bottle shoulder 113 to form a decorative section 122a. The decorative section 122a covers at least the limiting section 112b and the transition section 112c.

[0078] Exemplarily, the second limiting protrusion 1211 and the third limiting protrusion 1212 are arranged on the inner cap 121.

[0079] Exemplarily, the inner cap 121 is formed with an outer edge, and the inner wall of the outer cap 122 is formed with a protrusion. The inner cap 121 and the outer cap 122 are connected by axially limiting the outer edge of the inner cap 121 by the protrusion of the inner wall of the outer cap 122.

[0080] The outer cap 122 of the decorative section 122a extends to the bottle shoulder 113, which can cover the limiting section 112b and the transition section 112c, and make the outer cap 122 and the appearance of the glass bottle 11 more integral, and improve the appearance of the cosmetic container 10.

[0081] The second aspect of the embodiment of the present application provides a glass bottle 11, please refer to Figures 2 to 6 The glass bottle 11 is the glass bottle 11 of the cosmetic container 10 provided by any embodiment of the present application.

[0082] The glass bottle 11 provided by the embodiment of the present application, by arranging the first limiting protrusion 112d on the limiting section 112b of the neck 112 of the glass bottle 11, that is, by arranging the first limiting protrusion 112d close to the threaded section 112a, in this way, during the forming process of the glass bottle 11, the first limiting protrusion 112d can be extruded by the outer mold and the outer surface of the internal blowing needle together, which can increase the extrusion force, improve the stability of the forming of the first limiting protrusion 112d, thereby improving the position accuracy of the first limiting protrusion 112d, and further improving the yield and forming quality of the glass bottle 11.
