[0040] Example:

[0041] See also Figures 1 to 9 In this embodiment, a packaging container includes:

[0042] The main body 10 has a cavity for accommodating contents;

[0043] The liquid outlet head 20 is connected to the cavity and is slidably connected to the main body 10 along the axial direction;

[0044] A first cover 30 detachably covers the liquid discharge head 20 ;

[0045] A rotating shell 50 is provided with an opening at one end of the rotating shell 50 away from the main body 10. The rotating shell 50 is coaxially sleeved outside the liquid discharge head 20 and movably connected to the liquid discharge head 20. The rotating shell 50 is rotatably connected to the main body 10 about the axis of the rotating shell 50. The rotating shell 50 can rotate about the axis to drive the liquid discharge head 20 to move linearly back and forth along the axial direction;

[0046] When the liquid discharge head 20 is located at the first position, the covering edge of the liquid discharge head 20 and the first cover body 30 is accommodated in the rotating shell 50. When the liquid discharge head 20 is located at the second position, the covering edge of the liquid discharge head 20 and the first cover body 30 is exposed to the opening of the rotating shell 50.

[0047] In this embodiment, the rotation of the rotating shell 50 drives the liquid dispensing head 20 to move linearly back and forth along the axial direction, so that the covering edge of the liquid dispensing head 20 and the first cover body 30 can be accommodated or exposed by the rotating shell 50. When the covering edge of the liquid dispensing head 20 and the first cover body 30 is accommodated in the rotating shell 50, the rotating shell 50 can protect the liquid dispensing head 20 and the first cover body 30 from being accidentally opened by external force or collision. When the covering edge of the liquid dispensing head 20 and the first cover body 30 is exposed at the opening of the rotating shell 50, the user can lift the first cover body 30 to squeeze out or pour out the contents of the packaging container. The packaging container configured in this way is convenient to operate, cleverly reduces the risk of leakage of the contents of the packaging container, and improves the reliability and portability of the packaging container.

[0048] It should be known that the main body can be, but is not limited to, a variety of containers that can hold contents, such as a hose and a bottle; the liquid outlet head can be a common liquid outlet head with a liquid outlet hole, or it can be a nozzle-type liquid outlet head, a pump-type liquid outlet head or other types of liquid outlet heads. For various liquid outlet heads, the rotating shell can prevent the liquid outlet head from accidentally overflowing the contents.

[0049] Further, if Figure 2 and 3As shown, at least one spirally extending guide rail 21 is provided on the outer peripheral side of the liquid discharge head 20 , and a first clamping member 51 assembled on the guide rail 21 is protruded from the inner wall of the rotating shell 50 , and the first clamping member 51 can move along the guide rail 21 .

[0050] In this embodiment, it can be understood that when the rotating shell 50 rotates around the axis, the first clamping member 51 rotates along the rotating shell 50 around the axis. When the first clamping member 51 moves along the spiral guide rail 21, it can drive the liquid discharge head 20 to move axially.

[0051] Preferably, Figure 3 As shown, the side wall of the rotating shell 50 is provided with a notch 52 communicating with the opening;

[0052] The first cover 30 and the liquid dispensing head 20 are connected via a hinge 40 . When the liquid dispensing head 20 is located at the first position, the hinge 40 is exposed at the notch 52 .

[0053] In this embodiment, if Figure 4 As shown, when the liquid dispensing head 20 is in the second position, the covering edge of the liquid dispensing head 20 and the first cover 30 is exposed at the opening of the rotating shell 50. The notch 52 on the side wall of the rotating shell 50 increases the exposed area of ​​the liquid dispensing head 20 and the first cover 30, making it easier for the user to open the first cover 30 and improving the user experience of the packaging container. When the liquid dispensing head 20 is in the first position, the hinge 40 is cleverly exposed at the interface, further reducing the risk of accidental opening of the packaging container.

[0054] Preferably, Figure 2 As shown, in this embodiment, on the projection plane along the axis of the liquid dispensing head 20 , the first end of the guide rail 21 rotates 180° clockwise around the axis of the liquid dispensing head 20 and overlaps with the second end of the guide rail 21 .

[0055] With such arrangement, the rotation range of the rotating shell 50 is 180°. When the rotating shell 50 rotates 180° clockwise around the axis, the liquid discharge head 20 moves from the first position to the second position, and the notch 52 of the rotating shell 50 rotates from the position directly opposite the hinge 40 to the position on the liquid discharge head 20 opposite to the hinge 40. At this time, the position on the liquid discharge head 20 directly opposite the notch 52 makes it easy to lift the first cover body 30, which is more labor-saving.

[0056] Preferably, Figure 2 and 3 As shown, two spirally extending guide rails 21 are provided on the outer circumference of the liquid outlet head 20, and two first clamping members 51 are protruded from the inner wall of the rotating shell 50 and assembled on the two guide rails 21. This makes the matching relationship between the liquid outlet head 20 and the rotating shell 50 more stable.

[0057] In other embodiments, the guide rails 21 are not limited to two, and the guide rails 21 can be one or more, and the inner wall of the rotating shell 50 has a first clamping part 51 that matches each guide rail 21; on the projection surface along the axial direction of the liquid outlet head 20, the angle between the first end of the guide rail 21, the axis of the liquid outlet head 20 and the second end of the guide rail 21 is not limited to 180°, for example, it can also be 45°, 90°, 135°, 225° or other connecting angles.

[0058] Preferably, Figure 2 As shown, the guide rail 21 includes a first snap-fit ​​groove 211, a first track 212, a second track 213 and a second snap-fit ​​groove 214 connected in sequence. The first track 212 spirally extends from the first snap-fit ​​groove 211 to the second track 213, and the length extension direction of the second track 213 is perpendicular to the axial direction of the liquid discharge head 20.

[0059] Preferably, Figure 2 As shown, along the axial direction of the liquid discharge head 20, the projection of the first engaging groove 211 of one guide rail 21 overlaps with the projection of the second engaging groove 214 of the other guide rail 21, and the second engaging groove 214 of one guide rail 21 also overlaps with the projection of the first engaging groove 211 of the other guide rail 21. The two first engaging members 51 are disposed opposite to each other on the inner wall of the rotating shell 50.

[0060] The end of the liquid discharge head 20 close to the body 11 is defined as the bottom of the liquid discharge head 20, and the end of the liquid discharge head 20 away from the body 11 is defined as the top of the liquid discharge head 20. The first track 212 spirally extends from the first engaging groove 211 toward the bottom of the liquid discharge head 20.

[0061] The second snap-fit ​​groove 214 is connected to the bottom of the liquid discharge head 20 . The liquid discharge head 20 is also provided with a guide groove 215 connected from the second snap-fit ​​groove 214 to the outer surface of the liquid discharge head 20 . The guide groove 215 is provided on the side of the second snap-fit ​​groove 214 away from the bottom of the liquid discharge head 20 .

[0062] As can be understood from the above structure, the assembly process of the rotating shell 50 and the liquid discharge head 20 is as follows: align the first clip 51 on the rotating shell 50 with the second clip groove 214, so that the first clip 51 is inserted into the second clip groove 214 along the bottom to top direction of the liquid discharge head 20, and then continues to be inserted through the guide groove 215 along the bottom to top direction of the liquid discharge head 20. Since the first clip groove 211 of one guide rail 21 overlaps with the projection of the second clip groove 214 of the other guide rail 21 along the axial direction of the liquid discharge head 20, the first clip 51 will enter the first clip groove 211 after passing through the guide groove 215. At this time, the rotating shell 50 and the liquid discharge head 20 are assembled, the liquid discharge head 20 is in the first position, the covering edge of the liquid discharge head 20 and the first cover body 30 is accommodated in the rotating shell 50, and the hinge 40 is exposed at the notch 52 of the rotating shell 50.

[0063] Subsequently, the rotating shell 50 is assembled to the main body 10 to complete the overall assembly of the packaging container.

[0064] When the contents in the packaging container are to be squeezed out or poured out, the rotating shell 50 is rotated clockwise around the axis. The first clamping member 51 starts from the first clamping groove 211, passes through the first track 212 and the second track 213 in sequence to reach the second clamping groove 214. During the process of the first clamping member 51 passing through the first track 212, the covering edge of the liquid discharge head 20 and the first cover body 30 is gradually exposed to the opening of the rotating shell 50. During the process of the first clamping member 51 passing through the second track 213 to reach the second clamping groove 214, the liquid discharge head 20 rotates around the axis. When the second track 213 reaches the second clamping groove 214, the notch 52 of the rotating shell 50 rotates from the position opposite to the hinge 40 to the position opposite to the hinge 40 on the liquid discharge head 20, which is convenient for the user to open it.

[0065] To protect the liquid dispensing head 20 from damage caused by external collisions, the rotating shell 50 can be rotated clockwise around the axis to accommodate the liquid dispensing head 20 in the rotating shell 50 .

[0066] Preferably, any one or more of the rotating shell 50 and the liquid discharge head 20 is capable of elastic deformation, and a limiting protrusion is provided between the first clamping groove 211 and the first track 212, and between the second clamping groove and the second track 213. Specifically, any one or more of the rotating shell 50 and the liquid discharge head 20 is made of plastic. In this way, during the assembly process of the rotating shell 50 and the liquid discharge head 20 and during use, when the liquid discharge head 20 is moved to the first position or the second position, in the absence of external force applied to the rotating shell 50, the first clamping member 51 can be fixed in the first clamping groove 211 or the second clamping groove 214, so that the liquid discharge head 20 remains in the first position or the second position. Since any one or more of the rotating shell 50 or the liquid discharge head 20 is capable of elastic deformation, the user can apply external force to the rotating shell 50 to cause the first clamping member 51 to leave the first clamping groove 211 or the second clamping groove 214.

[0067] Further, if Figure 5 and 6 As shown, the main body 10 includes a body 11 and a connecting member 12 connected to the body 11;

[0068] The connecting member 12 includes a first liquid outlet pipe 121 connected to the cavity and a shell 122 sleeved outside the first liquid outlet pipe 121. The liquid outlet head 20 includes a second cover body 22 slidably assembled on the shell 122 and a second liquid outlet pipe 23 connected to the first liquid outlet pipe 121 and the second cover body 22.

[0069] Preferably, Figure 7As shown, a plurality of first anti-rotation ribs 1221 are evenly spaced apart on the outer periphery of the shell 122. Figure 2 As shown, a plurality of second anti-rotation ribs 221 are evenly spaced on the inner circumference of the second cover body 22, and the length extension direction of the first anti-rotation ribs 1221 and the second anti-rotation ribs 221 is parallel to the axial direction of the liquid outlet head 20. At least some of the adjacent first anti-rotation ribs 1221 among the plurality of first anti-rotation ribs 1221 form slide grooves in pairs, and each second anti-rotation rib 221 is inserted into the corresponding slide groove.

[0070] In this embodiment, compared with setting a separate slide groove on the outer periphery of the shell 122, multiple first anti-rotation ribs 1221 evenly spaced on the outer periphery of the shell 122 make the assembly between the connecting piece 12 and the liquid outlet head 20 more convenient and accurate.

[0071] It should be noted that the first anti-rotation rib 1221 and the second anti-rotation rib 221 are only a preferred example. In other embodiments, as long as the housing 122 and the second cover 22 can be slidably connected, they will suffice.

[0072] Further, if Figure 6 and 9 As shown, the first liquid outlet pipe 121 and the second liquid outlet pipe 23 are sealedly connected;

[0073] The second liquid outlet pipe 23 is sleeved outside the first liquid outlet pipe 121 , or the second liquid outlet pipe 23 is passed through the first liquid outlet pipe 121 .

[0074] In some embodiments, as Figure 9 As shown, the second liquid outlet pipe 23 is sleeved outside the first liquid outlet pipe 121. The inner wall of the second liquid outlet pipe 23 is annularly provided with a snap-fit ​​protrusion 231, which abuts against the outer wall of the first liquid outlet pipe 121, thereby achieving a sealed connection between the first liquid outlet pipe 121 and the second liquid outlet pipe 23. The connector 12 and the body 11 are integrally formed. In other embodiments, the connector 12 and the body 11 can also be detachably connected.

[0075] When the liquid outlet head 20 slides axially, the first liquid outlet pipe 121 and the second liquid outlet pipe 23 also slide relative to each other. If the sealing between the first liquid outlet pipe 121 and the second liquid outlet pipe 23 is poor, the contents in the packaging container may overflow through the gap between the first liquid outlet pipe 121 and the second liquid outlet pipe 23.

[0076] Preferably, in other embodiments, Figure 6 As shown, the second liquid outlet pipe 23 is provided inside the first liquid outlet pipe 121 . A sealing assembly 24 is provided around the inner periphery of the first liquid outlet pipe 121 . The sealing assembly 24 is in close contact with the outer wall of the second liquid outlet pipe 23 .

[0077] Further, if Figure 6As shown, the sealing assembly 24 includes an annular fixing member 241 and a sealing member 242. A snap-fit ​​groove 1211 is provided on the inner wall of the end of the first liquid outlet pipe 121 away from the main body 11. The fixing member 241 presses the sealing member 242 into the snap-fit ​​groove 1211. The sealing member 242 protrudes from the snap-fit ​​groove 1211 on the side facing the second liquid outlet pipe 23.

[0078] Specifically, if Figure 6 and 8 As shown, the fixing member 241 is coaxially provided with a first annular groove 2411, and the outer peripheral wall of the fixing member 241 protrudes a raised portion 2412. One side of the sealing member 242 is coaxially provided with a first annular protrusion 2421. The first annular protrusion 2421 of the sealing member 242 is inserted into the first annular groove 2411, and the raised portion 2412 of the fixing member 241 is clamped in the clamping groove 1211, so that the fixing member 241 presses the sealing member 242 into the clamping groove 1211, and the side of the sealing member 242 facing away from the first annular protrusion 2421 abuts against the second liquid outlet pipe 23, and the inner peripheral wall of the sealing member 242 is in close contact with the outer peripheral wall of the second liquid outlet pipe 23, thereby achieving further sealing between the first liquid outlet pipe 121 and the second liquid outlet pipe 23, effectively preventing the contents in the packaging container from leaking between the first liquid outlet pipe 121 and the second liquid outlet pipe 23, and improving the reliability of the packaging container.

[0079] Preferably, the connecting member 12 is detachably connected to the body 11 .

[0080] Specifically, if Figure 6 and 7 As shown, the body 11 is provided with a third liquid outlet pipe 111 that communicates with the cavity. The third liquid outlet pipe 111, the first liquid outlet pipe 121, and the second liquid outlet pipe 23 are coaxially arranged. The third liquid outlet pipe 111 is snap-connected to the end of the first liquid outlet pipe 121 that is close to the body 11. This arrangement allows the connector 12 to be detachable from the body 11, facilitating installation of the sealing assembly 24 on the connector 12.

[0081] Furthermore, the sealing member 242 may be made of rubber, polyurethane or other polymer materials that can be used for sealing.

[0082] Further, if Figure 3 and 7 As shown, an outer wall of the shell 122 close to the main body 11 is provided with an annular second clamping member 1222, and an inner wall of the rotating shell 50 close to the main body 11 is provided with an annular third clamping member 53, and the second clamping member 1222 is rotatably connected to the third clamping member 53.

[0083] The second clamping member 1222 and the third clamping member 53 enable the rotating shell 50 to be rotatably connected to the shell body 122. Specifically, the second clamping member 1222 is an annular groove protruding from the outer wall of one end of the shell body 122 close to the main body 11, and the third clamping member 53 is an annular protrusion protruding from the inner wall of one end of the rotating shell 50 close to the main body 11. The third clamping member 53 is clamped in the second clamping member 1222.

[0084] As can be understood from the above structure, after the rotating shell 50 and the liquid outlet head 20 are assembled, the process of assembling the rotating shell 50 and the liquid outlet head 20 to the main body 10 is as follows:

[0085] Align the second anti-rotation rib 221 on the second cover 22 of the liquid dispensing head 20 with the sliding groove formed by the multiple first anti-rotation ribs 1221 on the housing 122, and insert the second anti-rotation rib 221 into the corresponding sliding groove to slide the second cover 22 into the housing 122. Continuing, the third clamping member 53 of the rotating shell 50 is clamped into the second clamping member 1222 of the housing 122 to rotatably connect the rotating shell 50 to the housing 122. At this point, the liquid dispensing head 20 can only move axially when the rotating shell 50 is rotated.

[0086] Furthermore, an anti-theft ring 60 is connected to one end of the rotating shell 50 close to the main body 11, and a fourth clamping piece 1223 is provided at one end of the shell 122 close to the main body 11. The anti-theft ring 60 is sleeved outside the fourth clamping piece 1223 and clamped to the fourth clamping piece 1223.

[0087] The anti-theft ring 60 prevents unauthorized opening of the product and protects the contents of the packaging container from contamination. As will be appreciated, the rotating shell 50 and the anti-theft ring 60 are connected at a connection point and are integrally formed. During the assembly of the rotating shell 50 and the liquid discharge head 20 to the main body 10, the anti-theft ring 60 aligns with the fourth engaging member 1223 of the housing 122. When the packaging container is in use, the rotating shell 50 is rotated, causing the rotating shell 50 and the housing 122 to rotate relative to each other. Because the anti-theft ring 60 is engaged with the fourth engaging member 1223 of the housing 122, the connection point between the rotating shell 50 and the anti-theft ring 60 breaks during the rotation of the rotating shell 50.

[0088] The packaging container of the present invention adds a rotating shell 50 to the liquid dispensing head 20. When the rotating shell 50 rotates a certain angle in a clockwise direction around the axis, the liquid dispensing head 20 rises to a certain height. When the liquid dispensing head 20 moves to the second position, the covering edge of the liquid dispensing head 20 and the first cover 30 is exposed at the opening of the rotating shell 50, allowing the user to open the first cover 30. When the user is not using the product, the rotating shell 50 rotates another certain angle in a clockwise direction around the axis. The liquid dispensing head 20 lowers to a certain height. When the liquid dispensing head 20 moves from the second position to the first position, the covering edge of the liquid dispensing head 20 and the first cover 30 is accommodated within the rotating shell 50. The user can carry the packaging container with them without colliding or squeezing other objects, which may cause the first cover 30 to be accidentally opened. This reduces the risk of spillage of the contents of the packaging container and improves the reliability of the packaging container.

[0089] In addition, the packaging container in the present invention also has an anti-theft function before the first use. By providing an anti-theft ring 60 on the rotating shell 50, the product is prevented from being illegally opened, the contents are protected from contamination, and the message "this package has been opened" is clearly conveyed to the user, thereby effectively improving the anti-counterfeiting and safety of the product.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
