Description

Technical Field

[0001] This utility model relates to a cream jar, and more particularly to a press-type cream jar, wherein the press-type cream jar allows the user to operate it with one hand so that the user can take the cream from the press-type cream jar. Background Technology

[0002] Cream-based products are a basic form of daily chemical products such as face creams and eye creams. Patent application CN103373544A discloses a cream-dispensing packaging for holding cream-based products. It consists of a cream dispensing component and a container. The dispensing component includes a rotating cap mounted on top of the container. The rotating cap has a dispensing opening, and a spatula is located below the opening, with its tip positioned low. When force is applied to the rotating cap, it rotates against the top of the cream, and the cream flows along the spatula into the dispensing opening and continues onto the upper surface of the rotating cap, allowing the user to dispense the cream. It is understood that the amount of cream dispensed is related to the rotation angle of the rotating cap. However, in existing cream-dispensing packaging, there is no dedicated structure to control the rotation angle of the rotating cap. Users can only control the rotation angle by feel, thus controlling the amount of cream dispensed, which easily leads to problems of dispensing too much or too little cream. In addition, when users take the ointment, they often need to use one hand to hold the bottom of the container and the other hand to hold and rotate the cap. That is, users need to use both hands to operate the ointment packaging, which is quite troublesome. Utility Model Content

The term "a" should not be construed as a limitation on the quantity.

[0032] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 10 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the press-type cream jar includes a bottom shell 10, a track seat 20, a head cap 30, a cap 40, a drive column 50, an inner bottle 60, a piston 70, a first reset element 80, a second reset element 90, and a third reset element 100.

[0033] Specifically, the track seat 20 is mounted on the bottom shell 10. The track seat 20 has a column hole 21 and at least one track groove 22. The track groove 22 is provided on the hole wall of the track seat 20 for forming the column hole 21, and the track groove 22 extends in a spiral manner. The cap 30 is movably mounted on the bottom shell 10. The cap 30 has a cap cavity 31, at least one top ointment outlet 32, and at least one spatula 33. The top ointment outlet 32 ​​has a first opening edge 321, a second opening edge 322, and an ointment dispensing channel 323. The first opening edge 321 and the second opening edge 322 are opposite to each other. The ointment dispensing channel 323 is formed between the first opening edge 321 and the second opening edge 322 and communicates with the cap cavity 31. The spatula 33 is arranged to extend from the first opening edge 321 toward the second opening edge 322, and the height of the side of the spatula 33 adjacent to the second opening edge 322 is lower than the height of the second opening edge 322, that is, the front end of the spatula 33 is lower. The cap 40 has a cap hole 41 and is mounted on the bottom of the headgear 30. The cap hole 41 of the cap 40 is connected to the headgear cavity 31 of the headgear 30. The bottom of the first reset element 80 abuts against the track seat 20, and the top of the first reset element 80 abuts against the cap 40. The bottom of the drive column 50 has at least one protrusion 51. The bottom of the drive column 50 is rotatably mounted in the column hole 21 of the track seat 20. The protrusion 51 of the drive column 50 protrudes into the track groove 22 of the track seat 20. When the protrusion 51 of the drive column 50 slides along the track groove 22 of the track seat 20, the drive column 50 rotates relative to the track seat 20. The bottom of the second reset element 90 abuts against the bottom shell 10, and the top of the second reset element 90 abuts against the bottom of the drive column 50. The inner bottle 60 includes a bottle body 61 and a driven post 62 extending downward from the bottle body 61. The bottle body 61 has a bottle cavity 611 and a bottle opening 612 communicating with the bottle cavity 611. The bottle body 61 is rotatably mounted in the cap cavity 31 of the cap 30, and the cap 30 closes the bottle opening 612 of the bottle body 61. The bottom of the driven post 62 passes through the cap hole 41 of the cap 40, and the bottom of the driven post 62 and the top of the driving post 50 can be connected and separated. The piston 70 is movably mounted in the bottle cavity 611 of the bottle body 61. The bottom of the third reset element 100 abuts against the top of the driven post 62, and the top of the third reset element 100 abuts against the piston 70.

[0034] After the ointment 130 is filled into the cavity 611 of the bottle body 61, the ointment 130 is supported by the piston 70, and the third reset element 100 is in a pre-pressurized state. The piston 70 and the third reset element 100 cooperate with each other so that the top of the ointment 130 is always pressed against the part of the cap 30 used to close the bottle mouth 612 of the bottle body 61. In the natural state (when the cap 30 is not pressed), the second reset element 90 keeps the bottom of the driven column 62 and the top of the driving column 50 in a connected state. When the user presses down on the top of the cap 30, the cap 30, the cap 40, the drive column 50, the inner bottle 60, the piston 70, and the third reset element 100 move downward synchronously. At this time, on the one hand, the first reset element 80 and the second reset element 90 are compressed and deformed to accumulate elastic potential energy. On the other hand, the protrusion 51 of the drive column 50 slides along the track groove 22 of the track seat 20 during the downward movement of the drive column 50, so that the drive column 50 moves downward in a rotating manner. Since the second reset element 90 keeps the bottom of the driven column 62 and the top of the drive column 50 in a connected state, the drive column 50 drives the inner bottle 60 and the cream 130 to rotate synchronously. The spatula 33 of the cap 30 scrapes out the top part of the cream 130 through the cream outlet channel 323 of the cap 30. Understandably, after the top of the paste 130 is scraped out, the height of the paste 130 decreases, and the third reset element 100 pushes the piston 70 upward, allowing the top of the paste 130 to always be pressed against the cap 30. After the user releases pressure on the cap 30, the first reset element 80 pushes the cap 30, the cap 40, the inner bottle 60, the piston 70, and the third reset element 100 upward synchronously during the process of returning to the initial state. The second reset element 90 pushes the drive column 50 upward during the process of returning to the initial state. The protrusion 51 of the drive column 50 slides along the track groove 22 of the track seat 20 during the upward movement of the drive column 50, so that the drive column 50 moves upward in a rotational manner. During this process, the bottom of the driven column 62 and the top of the drive column 50 can separate to prevent the drive column 50 from causing the inner bottle 60 to rotate.

[0035] Therefore, compared with the prior art, in the press-type cream jar of this utility model, on the one hand, the user can take the cream 130 contained in the bottle cavity 611 of the bottle body 61 by pressing the top of the cap 30 with one hand. That is, the press-type cream jar of this utility model allows the user to operate with one hand, so that the user can take the cream from the press-type cream jar. On the other hand, each time the cap 30 is pressed to the bottom, the angle at which the track seat 20 drives the drive column 50 to rotate is the same, and the angle at which the drive column 50 drives the inner bottle 60 to rotate is the same. Thus, the press-type cream jar can help the user to take the cream in a measured amount.

[0036] When the user presses down on the top of the cap 30, in order to ensure that the driving column 50 is subjected to balanced force on both sides, in the press-type cream jar of this utility model, the number of track grooves 22 of the track seat 20 is two, and correspondingly, the number of protrusions 51 at the bottom of the driving column 50 is two. Each of the protrusions 51 of the driving column 50 protrudes into each of the track grooves 22 of the track seat 20, and each of the protrusions 51 of the driving column 50 slides along each of the track grooves 22 of the driving seat 20, so as to avoid the driving column 50 tilting during the up and down movement, thereby avoiding the "jamming" phenomenon. This is crucial for ensuring the smooth rotation of the driving column 50.

[0037] In the appendix Figures 1 to 10 In this specific example of the press-type cream jar of the present invention, the top of the drive column 50 has a set of first one-way helical teeth 52, and the bottom of the driven column 62 has a set of second one-way helical teeth 621. The first one-way helical teeth 52 of the drive column 50 and the second one-way helical teeth 621 of the driven column 62 can engage and disengage. In the natural state and during the downward pressing of the cap 30, the second reset element 90 engages the first one-way helical teeth 52 of the drive column 50 and the second one-way helical teeth 621 of the driven column 62, so that the bottom of the driven column 62 and the top of the drive column 50 are connected, thereby allowing the drive column 50 to drive the inner bottle 60 to rotate. When the cap 30 is released, the first one-way helical teeth 52 and the second one-way helical teeth 621 disengage, so that the bottom of the driven column 62 and the top of the drive column 50 are separated, thereby preventing the drive column 50 from driving the inner bottle 60 to rotate.

[0038] Furthermore, the bottom shell 10 includes a bottom plate 11 and a peripheral wall 12, and the bottom shell 10 has a bottom shell cavity 13 and a cavity opening 14. The peripheral wall 12 extends integrally upward from the periphery of the bottom plate 11. The bottom shell 10 forms the bottom shell cavity 13 between the bottom plate 11 and the peripheral wall 12. The peripheral wall 12 is used to form the cavity opening 14. The bottom of the cap 30 extends into the bottom shell cavity 13 through the cavity opening 14 of the bottom shell 10. In this way, whether the top of the cap 30 is pressed to allow the cap 30 to move downward relative to the bottom shell 10, or the cap 30 moves upward relative to the bottom shell 10 to return to its original position, the bottom shell 10 can prevent the cap 30 from tilting and limit the movement direction of the cap 30 to the height direction.

[0039] In the press-type cream bottle of this utility model, the track seat 20 is installed at the bottom of the bottom shell cavity 13 of the bottom shell 10, and the cap 40, the drive column 50 and the first reset element 80 are all housed in the bottom shell cavity 13 of the bottom shell 10, so that the track seat 20, the cap 40, the drive column 50 and the first reset element 80 are hidden.

[0040] Preferably, the track seat 20 has a bottom limiting groove 23, the bottom of the first reset element 80 is located in the bottom limiting groove 23 of the track seat 20, and the cap 40 has a top limiting groove 42, the top of the first reset element 80 is located in the top limiting groove 42 of the track seat 20. In this way, the opposite ends of the first reset element 80 can reliably abut against the track seat 20 and the cap 40. When the top of the cap 30 is pressed, causing the first reset element 80 to be compressed, the press-type cream jar can prevent the bottom of the first reset element 80 from sliding relative to the track seat 20 and / or prevent the top of the first reset element 80 from sliding relative to the cap 40.

[0041] Further, see Appendix Figures 2 to 4The track base 20 includes a base plate 24 and a track post 25 extending upward from the base plate 24. The post hole 21 and the track groove 22 of the track base 20 are both formed in the track post 25. In this specific example of the press-type cream jar of the present invention, the track base 20 is integral, that is, the track post 25 extends upward integrally from the base plate 24. The base plate 24 of the track base 20 is stacked on the base plate 11 of the bottom shell 10. After the second reset element 80 is placed in the post hole 21 of the track base 20 and surrounded by the track post 25, the bottom of the drive post 50 is installed in the post hole 21 of the track base 20, such that the opposite ends of the second reset element 90 abut against the base plate 11 of the bottom shell 10 and the bottom of the drive post 50, respectively.

[0042] Reference Appendix Figures 2 to 4 The peripheral wall 12 of the bottom shell 10 has at least one sliding groove 121 and at least one first locking groove 122. The sliding groove 121 extends from the top of the peripheral wall 12 toward the bottom plate 11, and the first locking groove 122 extends in a circumferential direction. The periphery of the seat plate 24 has at least one plate protrusion 241 and at least one first locking rib 242. The plate protrusion 241 of the seat plate 24 protrudes into the sliding groove 121 of the peripheral wall 12, and the first locking rib 242 of the seat plate 242 engages with the first locking groove 122 of the peripheral wall 12. In this way, the press-type cream jar can prevent the track seat 20 from rotating relative to the bottom shell 10 and prevent the track seat 20 from moving relative to the bottom shell 10 in the height direction. It is understood that in other examples of the press-type cream jar of this utility model, the peripheral wall 12 may not have the first slot 122 provided, and correspondingly, the periphery of the base plate 24 may not have the first retaining rib 242 provided. Since the bottom and top of the first reset element 80 abut against the base plate 24 and the cap 40 respectively, the base plate 242 can be prevented from moving relative to the bottom shell 10 in the height direction. (See attached...) Figures 1 to 10 In this specific example of the press-type cream jar of the present invention, the peripheral wall 12 has two grooves 121, which are positioned opposite each other. Correspondingly, the base plate 24 has two plate protrusions 241, which are positioned opposite each other. Each plate protrusion 241 of the base plate 24 protrudes into each groove 121 of the peripheral wall 12.

[0043] Continue to refer to the appendix Figure 2 and Figure 3The bottom shell 10 includes a guide post 15, which extends integrally upward from the bottom plate 11 and extends into the post hole 21 of the track seat 20. The second reset element 90 is fitted onto the guide post 15 of the bottom shell 10, and the drive post 50 is movably fitted onto the guide post 15. In this way, the second reset element 90 can be reliably held between the bottom plate 11 and the drive post 50, and the second reset element 90 will not tilt whether it is compressed or reset, thereby avoiding the second reset element 90 scraping against the hole wall of the track seat 20. Preferably, the driven post 62 has a clearance hole 622 to avoid the top of the guide post 15 of the bottom shell 10, so as to prevent the guide post 15 from hitting the driven post 62 when the head cap 30 is pressed down.

[0044] Continue to refer to the appendix Figures 2 to 4 The bottom of the cap 30 has at least one slider 34, which protrudes into the groove 121 of the peripheral wall 12 of the bottom shell 10. In this way, when the cap 30 is pressed downwards, the slider 34 and the groove 121 of the peripheral wall 12 cooperate to restrict the movement of the cap 30 to the height direction, preventing the cap 30 from rotating relative to the bottom shell 10. (See attached...) Figures 1 to 10 In this specific example of the press-type cream jar of the present invention shown, the cap 30 has two opposing sliders 34, each slider 34 of the cap 30 protruding into a groove 121 of the peripheral wall 12 of the bottom shell 10.

[0045] Continue to refer to the appendix Figures 2 to 4 The headgear 30 includes a headgear body 35 and a headgear ring 36. The headgear cavity 31, the top ointment outlet 32, and the spatula 33 of the headgear 30 are respectively disposed on the headgear body 35, and the headgear ring 36 is installed on the bottom of the headgear body 35. That is to say, in the attached Figures 1 to 10In this specific example of the press-type cream jar of the present invention, the cap 35 and the cap ring 36 are assembled after being manufactured separately. This facilitates the installation of the piston 70 into the cavity 611 of the bottle body 61 during the filling of the cream 130. Specifically, before the cap ring 36 is installed on the cap 35, the depth of the cap cavity 31 of the cap 30 is relatively shallow. After the cream 130 is filled into the cavity 611 of the bottle body 61, the operator can easily place the piston 70 into the cavity 611 of the bottle body 61. After the operator places the piston 70 into the cavity 611 of the bottle body 61, the driven post 62 can be installed at the bottom of the bottle body 61, and the opposite ends of the third reset element 100 abut against the piston 70 and the driven post 62, respectively. Subsequently, the cap ring 36 can be installed at the bottom of the cap 35. Optionally, in other examples of the press-type cream jar of this utility model, the cap 35 and the cap ring 36 may also be integrally formed.
