[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] refer to Figures 1 to 2 This application discloses a bottle body, including: a two-color bottle cap 100 and a bottle body (not shown in the figure), wherein the two-color bottle cap 100 is disposed on the bottle body.

[0043] In some possible embodiments, the two-color bottle cap 100 includes a lower connector 110 and an upper cap body 120. The lower connector 110 is provided with an opening 111 and includes a coaxial first portion 112 and a second portion 113, wherein the radius of the first portion 112 is smaller than the radius of the second portion 113.

[0044] The second part 113 includes a first area 115 and a second area 116. The first area 115 and the second area 116 are different colors. The upper cover 120 is attached to the first part 112 in a separable manner from the first part 112.

[0045] Using the above technical solution, the second part 113 includes a first zone 115 and a second zone 116. The first zone 115 and the second zone 116 are different colors. The bottle cap can be made to have two colors without adding a printing process. The operation is simpler, attracts consumers' attention, and has differentiation and high-end features.

[0046] It is understandable that the second part 113 may also include a third area, a fourth area, etc., with different colors. In other words, the second part 113 may present three, four, or more different colors.

[0047] For example, the first part 112 and the second part 113 are integrally formed. At the same time, the first part 112 and the second part 113 are different colors. For example, the first part 112 is red, the first area 115 of the second part 113 is blue, and the second area 116 is gray. It is understood that the embodiments of this application do not limit the colors of the first part 112 and the second part 113, and some colors of the first part 112 and the second part 113 may also be the same.

[0048] The first region 115 is four protrusions 117. The four protrusions 117 are different in color from the second region 116, and the four protrusions 117 are arranged at intervals on the outer peripheral edge of the second portion 113 and are integrally formed with the second region 116. The first region 115 and the second region 116 are made of different materials. The first region 115 is made of PP (Polypropylene) hard material, and the second region 116 is made of PP (Polypropylene) soft material. The first region 115 and the second region 116 may also be made of different compatible materials. That is, the first region 115 and the second region 116 are different in color and are integrally injection-molded from different materials in one step.

[0049] It can be understood that the outer surface of the first region 115 may also be flush with the outer surface of the second region 116, that is, the first region 115 does not protrude outward.

[0050] By adopting the above technical solution, the protrusions 117 and the second region 116 are integrally formed, and the protrusions 117 are different in color from the second region 116. That is, when the second portion 113 is injection-molded, it already includes the protrusions 117 and the second region 116 with different colors, so that the bottle cap can present two colors without secondary operations, the operation is simpler, and the product has differentiation and high-end properties.

[0051] It should be noted that the present application does not limit the number of the protrusions 117, and the number may also be one, two, three, five, etc.

[0052] Exemplarily, refer to Figure 1A , the four protrusions 117 include at least one of numbers, Chinese characters, letters, symbols or graphics. For example, as shown in the embodiment of the present application, the four protrusions 117 are respectively the number 1, the Chinese character "Wang", the letter C, and a circle in the graphics. But it is not limited thereto. The four protrusions 117 may all be numbers, or all be Chinese characters, or all be letters, or all be graphics, or all be symbols, or a combination of any four of them. Exemplarily, the four protrusions 117 are red, and the second region 116 is gray.

[0053] It should be noted that the embodiments of the present application do not limit the specific colors of the protrusions 117 and the second region 116. The protrusions 117 may also be yellow, and the second region 116 may be white, etc., as long as the colors of the protrusions 117 and the second region 116 are different.

[0054] Herein, refer to Figure 2AZone 115 and Zone 116 can be formed using either rotary two-color injection molding or co-injection two-color injection molding. Taking rotary two-color injection molding as an example, the injection mold contains two identical but differently positioned cavities (cavity A and cavity B). Each cavity is responsible for molding a portion of the bottle cap; cavity A molds the first part 112 and Zone 116, while cavity B molds the first zone 115. The moving mold side of the injection molding machine is mounted on a worktable that can rotate precisely 180 degrees. The injection mold has two independent gating systems (hot runner or cold runner), corresponding to two different colors of plastic (the first color and the second color). Specifically, for example, the first color is red and the second color is gray; each gating system only supplies material to the corresponding cavity.

[0055] The mold needs to precisely wrap around or adhere to the first molded portion during the second injection after rotation, forming a good weld or mechanical interlock at the boundary. After the second injection is completed and cooled, the ejection mechanism ejects the final two-color bottle cap. Both cavities require efficient cooling channels to control the cooling rate of the two materials, ensuring dimensional stability and shortening the cycle time.

[0056] Specifically, during the first injection, the mold is closed and the worktable is in the first position (cavity A is aligned with the red gate). The injection molding machine injects molten red plastic into cavity A, forming the first part 112 and the second area 116 of the two-color bottle cap 100. After a brief period of pressure holding and cooling, the second step is performed.

[0057] Open the mold and rotate the rotating table precisely 180 degrees. At this point, cavity A with the red semi-finished product rotates to the second position (aligned with the gray gate), while the empty cavity B rotates to the first position (aligned with the red gate).

[0058] Then, the mold closes again. The injection molding machine injects gray molten plastic into cavity B, and simultaneously injects gray molten plastic into cavity A, wrapping or adhering it to the previously formed red semi-finished product to form a complete two-color bottle cap 100. After sufficient pressure holding and cooling, the mold is opened, and the ejection mechanism ejects the completely solidified two-color bottle cap 100 from cavity A.

[0059] The red semi-finished product in cavity B remains inside the mold, awaiting gray injection molding after the next rotation. Step two and subsequent steps are repeated continuously to achieve continuous production. Each cycle produces one two-color bottle cap 100 and one single-color semi-finished product.

[0060] For example, refer to Figure 2 and Figure 5The outer periphery of the first part 112 is provided with a first external thread 118, and the upper cover 120 is provided with a first internal thread 121. The upper cover 120 is threadedly engaged with the first part 112 so that the upper cover 120 covers the first part 112. The outer periphery of the upper cover 120 is provided with rotating grooves 122 at intervals, thereby increasing the friction between the hand and the upper cover 120, so as to more easily and effortlessly unscrew the upper cover 120 and separate it from the lower connector 110.

[0061] It is understood that the connection method between the upper cover 120 and the lower connector 110 is not limited in the embodiments of this application; it can also be a flip-top design. (See reference...) Figure 6 and Figure 6A Specifically, the upper cover 120 and the lower connector 110 are connected by a connecting strap 140.

[0062] For example, refer to Figure 2 and Figure 5 The first part 112 also includes an extension 1121, which extends axially (i.e., Figure 2 The extension 1121 extends away from the second part 113 in the X direction shown. The radius of the extension 1121 is smaller than the radius of the first part 112. The upper cover 120 is provided with a groove 123 that mates with it. When the upper cover 120 is placed on the lower connector 110, the extension 1121 extends into the groove 123, and the first external thread 118 mates with the first internal thread 121.

[0063] For example, the two-color bottle cap 100 also includes a shoulder strap 130, which is connected to the lower edge of the upper cap body 120 and disposed between the upper cap body 120 and the second part 113. The shoulder strap 130 has a handle 131, which is pulled to tear off the shoulder strap 130 when the bottle needs to be opened, thereby separating the upper cap body 120 from the lower connector 110 and opening the bottle.

[0064] In some embodiments, reference Figures 3 to 4A The two-color bottle cap 100 also includes a third part 114. The first part 112 and the third part 114 are integrally molded. The color of the third part 114 can be the same as the color of the first part 112, for example, the first part 112 is red and the third part 114 is red, or it can be different, for example, the first part 112 is blue and the third part 114 is red. Similarly, the materials of the third part 114 and the first part 112 are different. For example, the first part 112 is made of rigid PP (Polypropylene), and the third part 114 is made of flexible PP (Polypropylene). The first part 112 and the third part 114 can also be made of different materials. That is, the first part 112 and the third part 114 are different colors and are injection molded from different materials in one step.

[0065] The radius of the third portion 114 is greater than the radius of the first portion 112, the second portion 113 is covered on the third portion 114, and the color of the third portion 114 is the same as the color of the first region 115. The first region 115 is four protrusions 117, the four protrusions 117 are disposed on the outer peripheral edge of the third portion 114 and are integrally formed with the third portion 114, the second portion 113 is provided with corresponding through holes 119, and the protrusions 117 pass through the through holes 119 to allow the second portion 113 to be sleeved on the third portion 114.

[0066] By adopting the above technical solution, the protrusions 117 are integrally formed with the third portion 114, that is to say, the third portion 114 already includes the protrusions 117 of the same color as itself when being injection molded, and the protrusions 117 pass through the through holes 119 of the second portion 113 and have a different color from the second region 116 of the second portion 113, so that the second portion 113 presents two colors, the bottle cap can present two colors without adding a printing process, the operation is simpler, and the product is differentiated and high-end.

[0067] It should be noted that the present application does not limit the number of the protrusions 117, which may also be one, two, three, five, etc.

[0068] Exemplarily, the four protrusions 117 include at least one of numbers, Chinese characters, letters, symbols or patterns. For example, as shown in the embodiment of the present application, the four protrusions 117 are respectively the number 1, the Chinese character Wang, the letter C and a circular pattern. But it is not limited thereto, the four protrusions 117 may all be numbers, or all be Chinese characters, or all be letters, or all be patterns, or all be symbols, or a combination of any four of them. Exemplarily, the four protrusions 117 are red, and the second region 116 is gray.

[0069] It should be noted that the embodiments of the present application do not limit the specific colors of the protrusions 117 and the second region 116, the protrusions 117 may also be yellow, and the second region 116 may be white, etc., as long as the colors of the protrusions 117 and the second region 116 are different.

[0070] Exemplarily, the outer peripheral edge of the first portion 112 is provided with a first external thread 118, the upper cap body 120 is provided with a first internal thread 121, and the upper cap body 120 is in threaded fit with the first portion 112, so that the upper cap body 120 is covered on the first portion 112. The outer peripheral edge of the upper cap body 120 is provided with rotation patterns 122 at intervals, so as to increase the friction between the human hand and the upper cap body 120, so that the upper cap body 120 can be unscrewed and separated from the lower connecting member 110 more conveniently and labor-savingly.

[0071] Exemplarily, reference is made to Figure 3 and Figure 5The first part 112 also includes an extension 1121, which extends axially (i.e., Figure 3 The extension 1121 extends away from the second part 113 in the X direction shown. The radius of the extension 1121 is smaller than the radius of the first part 112. The upper cover 120 is provided with a groove 123 that mates with it. When the upper cover 120 is placed on the lower connector 110, the extension 1121 extends into the groove 123, and the first external thread 118 mates with the first internal thread 121.

[0072] For example, the two-color bottle cap 100 also includes a shoulder strap 130, which is connected to the lower edge of the upper cap body 120 and disposed between the upper cap body 120 and the second part 113. The shoulder strap 130 has a handle 131, which is pulled to tear off the shoulder strap 130 when the bottle needs to be opened, thereby separating the upper cap body 120 from the lower connector 110 and opening the bottle.

[0073] In other possible embodiments, refer to Figure 7 and Figure 7A The two-color bottle cap 100 includes a lower connector 110, which includes a coaxial first part 112 and a second part 113. The first part 112 and the second part 113 are integrally formed and have the same radius. The first part 112 includes a third area 152 and a fourth area 153, which are different colors. The second part 113 includes a first area 115 and a second area 116, which are different colors.

[0074] It should be noted that the embodiments of this application do not limit the colors of the first region 115, the second region 116, the third region 152, and the fourth region 153. The colors of the first region 115, the second region 116, the third region 152, and the fourth region 153 can be as shown in the embodiments of this application (i.e., as shown in the embodiments of this application). Figure 7A As shown, the first zone 115 and the third zone 152 are red, and the second zone 116 and the fourth zone 153 are gray. Alternatively, the first zone 115 and the third zone 152 can be yellow, and the second zone 116 and the fourth zone 153 can be white. At the same time, the first zone 115 and the third zone 152 can be different, and the colors of the second zone 116 and the fourth zone 153 can also be different. Alternatively, the colors of the second zone 116, the third zone 152, and the fourth zone 153 can be the same, only different from the color of the first zone 115.

[0075] For example, the lower connector 110 is detachably attached to the bottle body.
