Description

Technical Field

[0001] This utility model relates to cosmetic bottle technology, and more specifically, to face cream bottles. Background Technology

[0002] A face cream jar is a container used to hold face cream-type skincare products. In the present technology, a face cream jar generally includes a bottle body and a bottle cap. An inner liner is placed inside the bottle body, and the cream-type cosmetic is placed inside the inner liner. Usually, an inner cap is placed at the opening of the inner liner.

[0003] During transportation, the face cream bottle may shake due to bumps, but the inner cap design can effectively prevent the face cream from spilling or getting on the cap, keeping the cap clean and the cream tidy.

[0004] In real life, when people use face cream, they usually hold the bottle with one hand and unscrew the cap with the other, then put the inner cap aside before using the face cream. After using the face cream, the inner cap may be forgotten, causing face cream to get into the cap later.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a face cream bottle.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a face cream bottle, including a bottle body and a bottle cap, wherein an inner cavity is formed in the bottle body, and a circular protrusion for installing the bottle cap is formed on the bottle body. An opening communicating with the inner cavity is opened on the side wall of the circular protrusion facing away from the bottle body. An inner cap for covering the opening is detachably connected to the bottle body. A semi-thread one is formed on the outer peripheral wall of the circular protrusion, and a semi-thread two is formed on the inner cap. The semi-thread one and the semi-thread two can be spliced ​​to form an external thread. An internal thread for cooperating with the external thread is opened on the inner peripheral wall of the bottle cap.

[0008] The present invention is further configured such that: the top surface of the bottle body is provided with an annular groove, the inner cap includes a cap that can be embedded in the groove and an arc-shaped ring wall fixedly connected to one end of the cap, and the semi-thread is formed on the arc-shaped convex surface of the ring wall.

[0009] The present invention is further configured such that: a positioning groove communicating with the groove is provided on the outer peripheral wall of the circular protrusion, and a positioning strip for embedding in the positioning groove is formed on the arc-shaped concave surface of the ring wall.

[0010] The present invention is further configured such that: all inner walls of the positioning groove are provided with guide slopes at one end near the groove.

[0011] The present invention is further configured such that: a recess is formed on the side of the cover facing away from the ring wall, and a sealing part that can be embedded in the opening is formed on the side of the cover facing the ring wall.

[0012] The present invention is further configured such that a groove is formed on the inner wall of the recess.

[0013] The present invention is further configured such that the inner cover is made of PP material.

[0014] In summary, this utility model has the following beneficial effects: When people forget to install the inner cap on the bottle after using the face cream and directly install the bottle cap on the bottle body, the bottle body only has a partial thread one, which causes the bottle cap to not be able to be tightened on the bottle body. People can clearly feel that the bottle cap cannot be fixed on the bottle body. This feedback can effectively remind people to install the inner cap on the bottle body, so that the inner cap can better prevent face cream from sticking to the bottle cap. At the same time, when the bottle cap is tightened on the circular protrusion, the pressure of the inner thread on the second partial thread can better press the inner cap against the opening, which can better ensure the sealing performance of the inner cap to the opening.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Face cream jar, such as Figure 1 and Figure 2As shown, the device includes a bottle body 1 and a bottle cap 2. An inner cavity 3 is formed within the bottle body 1. A circular protrusion 4 for mounting the bottle cap 2 is formed on the bottle body 1. An opening communicating with the inner cavity 3 is opened on the side wall of the circular protrusion 4 facing away from the bottle body 1. An inner cap for covering the opening is detachably connected to the bottle body 1. A semi-thread 6 is formed on the outer peripheral wall of the circular protrusion 4, and a semi-thread 7 is formed on the inner cap. Semi-thread 6 and semi-thread 7 can be joined to form an external thread. The arc length of semi-thread 6 on the projected plane is no greater than half the circumference of the external thread. An internal thread 8 for engaging with the external thread is opened on the inner peripheral wall of the bottle cap 2. When people finish using face cream and forget to install the inner cap on bottle 1, and directly install the cap 2 on bottle 1, the cap 2 cannot be tightened on bottle 1 because bottle 1 only has a half-thread 6. People can clearly feel that the cap 2 cannot be fixed on bottle 1. This feedback can effectively remind people to install the inner cap on bottle 1, so that the inner cap can better prevent face cream from getting on the cap 2. At the same time, when the cap 2 is tightened on the circular protrusion 4, the pressure of the inner thread 8 against the half-thread 7 can better press the inner cap against the opening, which can better ensure the sealing of the inner cap to the opening.

[0022] like Figures 1 to 4As shown, the top surface of the bottle body 1 has an annular groove 9. The inner cap includes a cap 10 that can be embedded in the groove 9 and an arc-shaped annular wall 11 fixedly connected to one end of the cap 10. A semi-threaded thread 7 is formed on the arc-shaped convex surface of the annular wall 11. When the inner cap is installed on the circular protrusion 4, the cap 10 is inserted into the groove 9 by hand, so that the cap 10 does not protrude from the surface of the circular protrusion 4, thus allowing the bottle cap 2 to be tightened better on the circular protrusion 4. A positioning groove 12 communicating with the groove 9 is formed on the outer peripheral wall of the circular protrusion 4. A positioning strip 13 for embedding in the positioning groove 12 is formed on the arc-shaped concave surface of the annular wall 11. When the inner cap is installed on the circular protrusion 4, the positioning groove 12 is first aligned with the positioning strip 13, and then the inner cap is moved so that the inner wall of the positioning groove 12 moves along the outer wall of the positioning strip 13. After the inner cap is completely installed on the circular protrusion 4, the bottle can be... When the cap 2 is screwed into the circular protrusion 4, the internal thread 8 and the second half thread 7 abut against each other. The force applied by the user's hand to the cap 2 is transmitted to the second half thread 7 through the internal thread 8. This force causes the inner cap to rotate in the same direction as the cap 2. The positioning strip 13 embedded in the positioning groove 12 can play a good positioning role for the inner cap, thus preventing the inner cap from rotating with the cap 2. This ensures that the cap 2 can be screwed tightly onto the bottle body 1. All inner walls of the positioning groove 12 have guide slopes 14 at the end near the groove 9. During the process of aligning the positioning strip 13 with the positioning groove 12, the setting of the guide slopes 14 makes the positioning groove 12 have a larger space to accommodate the positioning strip 13. This allows the positioning strip 13 to enter the positioning groove 12 better along the guide slopes 14, so that the user can quickly install the positioning strip 13 in the positioning groove 12.

[0023] like Figures 2 to 4As shown, a recess 16 is formed on the side of the cover 10 facing away from the annular wall 11, and a sealing part 15 is formed on the side of the cover 10 facing the annular wall 11, which can be embedded in the opening. The recess 16 and the sealing part 15 are formed on the cover 10 in one step by a stamping process. The diameter of the sealing part 15 is slightly larger than the diameter of the opening. When the cover 10 is installed in the groove 9, it is necessary to fold the cover 10 and forcefully insert the sealing part 15 into the opening, causing the sealing part 15 to deform. The deformed sealing part 15 generates an internal force to overcome the deformation under the action of its own material. This internal force can effectively increase the friction between the sealing part 15 and the inner wall of the opening. The force is applied to prevent the sealing part 15 from coming out of the opening, further ensuring the sealing performance of the cap 10 to the opening. A groove 5 is provided on the inner wall of the recess 16. When people remove the inner cap, they can pry their fingernail into the groove 5 and lift the inner cap with the back of the bottle body 1. The groove 5 provides a good point of force to remove the sealing part 15 from the opening. The inner cap is made of PP material. PP material has good chemical stability and good processing performance. The inner cap made of PP material can be processed well while ensuring that it will not react with the face cream, making the molding of the semi-thread 2 7 more convenient.
