Description

A packaging container for a cosmetic cream. Technical Field

[0001] This utility model belongs to the field of cosmetic container technology, specifically relating to a packaging container for cosmetic creams. Background Technology

[0002] Existing cosmetic cream packaging containers on the market require users to directly open the lid and use their hands or makeup tools to remove the cream from the container. This is inconvenient, and the cream is exposed when the container is opened, making it prone to spillage when tilted, leading to contamination and waste. Furthermore, it is difficult to control the amount of cream dispensed. Therefore, to address these issues, a rotating dispensing packaging container has been designed to better meet practical usage needs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a packaging container for cosmetic creams, thereby solving the problems mentioned in the background art, such as inconvenience in taking out cosmetic creams, easy contamination, waste, and difficulty in ensuring the amount of cream taken out.

[0004] The present invention provides a packaging container for cosmetic ointments, comprising a storage container, a dispensing head, and an ointment pushing mechanism; the dispensing head is axially rotatably sleeved on the upper part of the outer peripheral wall of the storage container, and the dispensing head has a dispensing port; the ointment pushing mechanism includes a rotating component, a screw, and a piston, the rotating component being sleeved on the lower part of the outer peripheral wall of the storage container; the top end of the screw is inserted and connected to the dispensing head, and the bottom end penetrates the bottom of the storage container and extends to the inner bottom surface of the rotating component and is rotatably connected to the inner bottom surface of the rotating component; a hollow hole penetrating the upper and lower end faces of the piston is provided at the middle position of the piston, and a thread is provided on the inner wall of the hollow hole, which engages with the thread of the screw; the piston has a peripheral surface that contacts the inner peripheral wall of the storage container, and an axial transmission structure is provided between the piston and the inner peripheral wall of the storage container for driving the piston to rise along the inner wall of the storage container.

[0005] As a further embodiment of this utility model, the axial transmission structure is at least one axial protrusion provided on the inner wall of the storage container and a corresponding axial groove provided on the outer wall of the piston; or the axial transmission structure is an axial groove provided on the inner wall of the storage container and a corresponding axial protrusion provided on the outer wall of the piston.

[0006] As a further embodiment of this utility model, the bottom end of the screw is provided with a cylindrical sleeve, and the inner bottom surface of the rotating assembly is provided with a rotating shaft that rotatably engages with the cylindrical sleeve; or the bottom end of the screw is provided with a rotating shaft, and the inner bottom surface of the rotating assembly is provided with a cylindrical sleeve that rotatably engages with the rotating shaft.

[0007] As a further embodiment of this utility model, the inner peripheral wall of the discharge head is provided with a positioning flange, and the outer peripheral wall of the storage container is provided with an axial positioning groove that cooperates with the positioning flange.

[0008] As a further embodiment of this utility model, the bottom of the storage container is provided with a plurality of annularly distributed guide teeth, and the outer side of the cylindrical sleeve is provided with a radially extending circular block, the upper surface of which is provided with a rotation stop part that meshes with the guide teeth.

[0009] The cooperative structure of the guide teeth and the rotating stop can prevent the rotating component from rotating in the opposite direction when it drives the storage container to rotate, thereby limiting the downward movement of the piston, avoiding back suction of the paste and avoiding the formation of an air layer on the surface of the paste, reducing user inconvenience, and making the paste more uniform during the extrusion process.

[0010] As a further embodiment of this invention, the guide tooth is trapezoidal in shape, and the longitudinal section of the rotation stop is a right-angled trapezoid. The inclined surface of the trapezoidal tooth of the guide tooth is opposite to the inclined surface of the rotation stop. Through these two opposing inclined surfaces, during relative rotation, the inclined surface of the guide tooth can slide along the inclined surface of the stop. When the outer screw rotates, the right-angled position of the rotation stop contacts the right-angled position of the guide tooth, preventing relative sliding. This stop structure is simple and low-cost; moreover, during rotary extrusion, the guide tooth produces a mechanical noise indicating a skipping motion, enhancing the user experience.

[0011] As a further embodiment of this invention, the axial transmission structure includes two symmetrically arranged axial protrusions on the inner wall of the storage container, and a corresponding axial groove penetrating the outer wall of the piston. Under the constraint of the screw and the axial protrusions, the piston is forced to rise along the inner wall of the storage container, extruding the material from the outlet, thereby achieving automatic extrusion of the paste.

[0012] As a further embodiment of this invention, a dust cover is fitted over the outer side of the discharge head, and the dust cover is detachably snapped together with the rotating component. This type of connection structure is a relatively mature technology and will not be described in detail here. This protects the discharge head from getting dirty when not in use, and also prevents the discharge head from rotating relative to the rotating component, thus preventing the ointment from seeping out.

[0013] As a further embodiment of this utility model, the rotating assembly is fitted with a housing.

[0014] When using this invention, hold the discharge head and rotate the outer shell. The rotating component and the storage container rotate synchronously with the outer shell. The axial transmission structure forces the piston to rotate around the screw and generate an axial upward movement under the screw thread engagement. The upper end of the piston pushes the paste upward and squeezes it out from the discharge port. The amount of paste squeezed out can be controlled according to the rotation amplitude, making it very convenient to take out the paste and reducing material waste.

[0015] The beneficial effects of this utility model are as follows: the packaging container uses a spiral extrusion method to dispense the cream, taking out only the appropriate amount at a time, while the rest of the material remains under the protection of the packaging material. This is convenient to use, avoids contamination of the user's hands, is cleaner and more hygienic, and effectively prevents accidental spillage of the cream, thus avoiding waste. In addition, the overall size is small and easy to carry, and can be placed in a cosmetic bag for use anytime, anywhere. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] As shown in Figures 1-5, a packaging container for a cosmetic cream includes a storage container 1, a dispensing head 2, and a cream pushing mechanism 3. The dispensing head 2 is axially rotatable and fitted onto the upper part of the outer peripheral wall of the storage container 1, and has a dispensing port 21. The cream pushing mechanism 3 includes a rotating assembly 31, a screw 32, and a piston 33. The rotating assembly 31 is fitted onto the lower part of the outer peripheral wall of the storage container 1. The rotating assembly 31 and the storage container 1 can be connected by snap-fit, plug-in, welding, or adhesive. The top end 321 of the screw 32 is plugged into the dispensing head 2, and the bottom end... 322 penetrates the bottom of the storage container 1 and extends to the inner bottom surface of the rotating component 31 and is rotatably connected to the inner bottom surface of the rotating component 31. A hollow hole 331 is provided at the middle position of the piston 33, which passes through the upper and lower end faces of the piston 33. A thread is provided on the inner wall of the hollow hole 331, which is engaged with the thread of the screw 32. The cavity of the storage container 1 is cylindrical. The piston 33 has a peripheral surface 332 that contacts the inner peripheral wall of the storage container 1. An axial transmission structure 4 is provided between the piston 33 and the inner peripheral wall of the storage container 1 to drive the piston 33 to rise along the inner wall of the storage container 1.

[0026] The axial transmission structure 4 includes two symmetrically arranged axial protrusions 11 on the inner wall of the storage container 1, and an axial groove 333 penetrating the outer wall of the piston 33. Under the constraint of the screw 32 and the axial protrusions 11, the piston 33 is forced to rise along the inner wall of the storage container 1, extruding material from the outlet 21, thereby achieving automatic extrusion of the paste. In other embodiments, the axial transmission structure 4 is replaced by another method: the axial transmission structure 4 includes two symmetrically arranged axial grooves on the inner wall of the storage container 1, and an axial protrusion penetrating the outer wall of the piston 33.

[0027] The bottom end 322 of the screw 32 is provided with a cylindrical sleeve 323, and the inner bottom surface of the rotating assembly 31 is provided with a rotating shaft 311 that rotatably engages with the cylindrical sleeve 323. The inner diameter of the cylindrical sleeve 323 is 0.05-0.15 mm larger than the outer diameter of the rotating shaft 311. In other embodiments, an alternative method can be used: the bottom end 322 of the screw 32 is provided with a rotating shaft, and the inner bottom surface of the rotating assembly 31 is provided with a cylindrical sleeve that rotatably engages with the rotating shaft.

[0028] The inner peripheral wall of the discharge head 2 is provided with a positioning flange 22, and the outer peripheral wall of the storage container 1 is provided with an axial positioning groove 12 that mates with the positioning flange 22. In other embodiments, another method can be used instead: the inner peripheral wall of the discharge head 2 is provided with an axial positioning groove, and the outer peripheral wall of the storage container 1 is provided with a positioning flange that mates with the axial positioning groove.

[0029] The bottom of the storage container 1 is provided with a number of annularly distributed guide teeth 13, and the outer side of the cylindrical sleeve 323 is provided with a radially extending circular block 324. The upper surface of the circular block 324 is provided with a rotation stop part 325 that meshes with the guide teeth 13.

[0030] Through the cooperative structure of the guide tooth 13 and the rotation stop part 325, the rotation can be reversed when the rotating component 31 drives the storage container 1 to rotate, thereby limiting the downward movement of the piston 33, avoiding back suction of paste and avoiding the formation of an air layer on the surface of the paste, reducing user inconvenience, and making the paste more uniform during the extrusion process.

[0031] The guide tooth 13 is trapezoidal in shape, and the longitudinal section of the rotating stop is a right-angled trapezoid. The inclined surface of the trapezoidal tooth 13 is opposite to the inclined surface of the stop. Through the two opposing inclined surfaces, the inclined surface of the guide tooth 13 can slide along the inclined surface of the stop during relative rotation. When the outer screw 32 rotates, the right-angle position of the rotating stop contacts the right-angle position of the guide tooth 13, preventing relative sliding. This stop structure is simple and low in cost. Moreover, during the rotary extrusion process, the guide tooth 13 produces a mechanical sound of skipping, enhancing the user experience.

[0032] A dust cover 5 is fitted over the outer side of the discharge head 2. The dust cover 5 is detachably snapped onto the rotating component 31. This type of connection structure is a mature technology and will not be described in detail here. This protects the discharge head 2 from getting dirty when not in use, and also prevents the discharge head from rotating relative to the rotating component 31, thus preventing the paste from leaking out. A housing 6 is fitted over the outer side of the rotating component 31. The upper end of the housing 6 matches the lower end of the dust cover 5, enhancing the overall sealing and aesthetics.

[0033] When using this invention, hold the discharge head 2, rotate the outer shell 6, and the rotating component 31 and the storage container 1 will rotate synchronously with the outer shell 6. The axial transmission structure 4 forces the piston 33 to rotate around the screw 32, and under the threaded engagement of the screw 32, it will move upward axially. The upper end of the piston 33 pushes the paste upward and squeezes it out from the discharge port 21. The amount of paste squeezed out can be controlled according to the rotation amplitude, making it very convenient to take out the paste and reducing material waste.

[0034] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
