Description

Technical Field

[0001] This utility model relates to a cream bottle, and more particularly to a rotating cream bottle. Background Technology

[0002] Creams and lotions are typically packaged in jars, and are scooped out with a spoon. For example, Chinese utility model patent CN220423369U discloses a flip-top replaceable rotating cream jar, comprising an outer bottle, an inner liner, and a base. The outer bottle has a hinged flip-top on one side of the bottle opening, with symmetrical lugs protruding along one edge of the hinge. The base contains the inner liner, whose top opening is sealed within the base's opening by the bottle opening. The top opening of the inner liner is aligned with the bottle opening. The base has symmetrical L-shaped slots on its outer diameter, with one end of the slot... The outer bottle has symmetrical locking ribs on its bottom inner diameter, which are connected to the opening of the base. The inner liner is placed into the base's opening, and after the locking ribs of the bottle are aligned with the slots on the base, the bottle is rotated clockwise until the locking ribs are engaged with the bottom of the slots, parallel to the other end. The bottle is then locked and fixed to the base. The bottle opening and the top opening of the inner liner are press-fitted and aligned. The top opening of the replacement inner liner has a heat-sensitive aluminum foil gasket. The top of the flip-top of the outer bottle has symmetrically arranged and raised spoon-shaped ribs, and the spoon is secured between these ribs. In use, the user first flips the cap open, then removes the spoon, and then uses the spoon to scoop out the cream contained in the inner liner. This method has many drawbacks. First, the spoon needs to be removed from the flip-top before use, and then reattached after use, making the process cumbersome. Second, using a spoon to scoop out the cream contained in the inner container makes it inconvenient for users to control the amount of cream used, and the scooping process can easily contaminate the remaining cream.

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

[0040] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 15 A preferred embodiment of the present invention, a rotating cream bottle, will be disclosed and described in the following description, wherein the rotating cream bottle includes a bottle body 10, a piston 20, a drive seat 30, a lifting column 40, and a cap 50.

[0041] Specifically, the bottle body 10 has a cavity 101 and a bottom through-hole 102 and a top opening 103 respectively communicating with the cavity 101. The piston 20 is movably mounted in the cavity 101 of the bottle body 10, and the peripheral wall of the piston 20 is in contact with the inner wall of the bottle body 10. In this way, the cream 100 filled in the cavity 101 of the bottle body 10 can be carried by the piston 20 and moves up and down synchronously with the up and down movement of the piston 20. That is, the piston 20 can carry the cream 100 up and down in the cavity 101 of the bottle body 10. The drive seat 30 is rotatably mounted below the bottle body 10, that is, the drive seat 30 can rotate relative to the bottle body 10. The top of the lifting column 40 is fixedly disposed on the piston 20, the bottom of the lifting column 40 passes through the bottom perforation 102 of the bottle body 10, and the bottom of the lifting column 40 is drivably connected to the drive seat 30, which drives the lifting column 40 to rise and fall relative to the bottle body 10. The cap 50 has at least one access slot 501, which penetrates the upper and lower surfaces of the cap 50, wherein the cap 50 is mounted on the top of the bottle body 10 and closes the top opening 103 of the bottle body 10.

[0042] When the drive seat 30 drives the lifting column 40 to rise relative to the bottle body 10, the lifting column 40 drives the piston 20 to move upward within the bottle cavity 101 of the bottle body 10. The cream 100 carried by the piston 20 moves upward synchronously. During this process, the cream 100 is squeezed out from the dispensing groove 501 of the cap 50, thus realizing the dispensing of the cream 100. This not only makes the dispensing of the cream 100 more convenient, but also avoids the remaining cream 100 from being contaminated during the dispensing process.

[0043] It is understood that the shape of the cream 100 squeezed out from the dispensing groove 501 of the cap 50 depends on the shape of the dispensing groove 501 of the cream 50. For example, in the attached... Figures 1 to 15 In this specific example of the rotating cream bottle shown, the dispensing slot 501 of the cap 50 is elongated and extends outward from the middle of the cream 50.

[0044] Further, see Appendix Figures 3 to 6 , Figure 9 and Figure 10The drive seat 30 has a seat hole 301, the position of which corresponds to the position of the bottom through hole 102 of the bottle body 10. The inner wall of the drive seat 30 defining the seat hole 301 is provided with an internal thread 31. Correspondingly, the bottom of the lifting column 40 has an external thread 41. The bottom of the lifting column 40 extends into the seat hole 301 of the drive seat 30, and the external thread 41 of the lifting column 40 and the internal thread 31 of the drive seat 30 match each other so that the bottom of the lifting column 40 is drivably connected to the drive seat 30. Thus, when the drive seat 30 rotates relative to the bottle body 10, the external thread 41 of the lifting column 40 and the internal thread 31 of the drive seat 30 cooperate to drive the lifting column 40 to rise and fall relative to the bottle body 20.

[0045] When the drive seat 30 rotates relative to the bottle body 10 to drive the lifting column 40 to rise and fall relative to the bottle body 10, in order to prevent the lifting column 40 from rotating relative to the bottle body 10, the bottom perforation 102 of the bottle body 10 is designed as a non-circular hole, and the cross-sectional shape and size of the bottom of the lifting column 40 match the shape and size of the bottom perforation 102 of the bottle body 10. For example, in the attached... Figures 1 to 15 In this specific example of the rotating cream bottle of the present invention shown, the bottom perforation 102 of the bottle body 10 is shaped like a racetrack, and correspondingly, the bottom cross-sectional shape of the lifting column 40 is also racetrack shaped.

[0046] Furthermore, the bottle body 10 has a receiving cavity 104 and a bottom opening 105 communicating with the receiving cavity 104. At least a portion of the drive seat 30 extends into the receiving cavity 104 of the bottle body 10, and the drive seat 30 closes the bottom opening 105 of the bottle body 10. In this way, not only can the drive seat 30 be reliably installed below the bottle body 10, but it also helps to reduce the height of the rotating cream bottle, thereby miniaturizing the rotating cream.

[0047] Specifically, the bottle body 10 includes a bottom plate 11, an upper cylindrical body 12, and a lower cylindrical body 13. A bottom perforation 102 is formed in the bottom plate 11. The upper cylindrical body 12 extends integrally upward from the periphery of the bottom plate 11 to form the bottle cavity 101 between the bottom plate 11 and the upper cylindrical body 12, and the upper cylindrical body 12 also forms the top opening 103 of the bottle body 10. The lower cylindrical body 13 extends integrally downward from the periphery of the bottom plate 11 to form the receiving cavity 104 between the bottom plate 11 and the lower cylindrical body 13, and the lower cylindrical body 13 also forms the bottom opening 105 of the bottle body 10. Preferably, the bottom plate 11, the upper cylindrical body 12, and the lower cylindrical body 13 of the bottle body 10 are integrally formed, and injection molding can mold the plastic into an integral bottle body 10.

[0048] The piston 20 is made of a flexible material, such as silicone or rubber. The outer diameter of the piston 20 is slightly larger than the inner diameter of the upper cylinder 12 of the bottle body 10. This allows the inner wall of the upper cylinder 12 to slightly compress the outer wall of the piston 20, ensuring a tight fit between the inner wall of the upper cylinder 12 and the outer wall of the piston 20. When the piston 20 moves up and down within the bottle cavity 101 of the bottle body 10, leakage of the cream 100 carried by the piston 20 to the bottom of the piston 20 is prevented.

[0049] The drive base 30 includes an assembly cylinder 32, a drive cylinder 33, and a driven cylinder 34. The drive cylinder 33 extends upward from the top of the assembly cylinder 32, and its outer diameter is smaller than that of the assembly cylinder 32. The seat hole 301 and the internal thread 31 of the drive base 30 are formed in the drive cylinder 33. The driven cylinder 34 extends downward from the bottom of the assembly cylinder 32, and its outer diameter is larger than that of the assembly cylinder 32. The outer diameter of the assembly cylinder 32 matches the inner diameter of the lower cylinder 13, and the outer diameter of the driven cylinder 34 is the same as that of the lower cylinder 13. After the assembly cylinder 32 and the drive cylinder 33 extend into the receiving cavity 104 of the bottle body 10, the driven cylinder 34 is exposed at the bottom of the bottle body 10 and is used to close the bottom opening 105 of the bottle body 10. When the driven cylinder 34 is rotated, the driven cylinder 34 drives the assembly cylinder 32 and the driving cylinder 33 to rotate synchronously.

[0050] To ensure that the mounting cylinder 32 of the drive seat 30 is reliably and rotatably mounted on the lower cylinder 13 of the bottle body 10, refer to the attached drawing. Figure 8The inner wall of the lower cylinder 13 of the bottle body 10 is provided with at least one annular rotating groove 131, and the outer wall of the assembly cylinder 32 is provided with at least one protruding ring 321. The protruding ring 321 of the assembly cylinder 32 extends into the rotating groove 131 of the lower cylinder 13. In this way, not only can the assembly cylinder 32 be rotated relative to the lower cylinder 13 of the bottle body 10, but the assembly cylinder 32 can also be prevented from falling out of the receiving cavity 104 of the bottle body 10.

[0051] The cap 50 is installed on the upper cylindrical body 12 of the bottle body 10 to mount the cap 50 on the top of the bottle body 10, thereby closing the top opening 103 of the bottle body 10. Specifically, the cap 50 has a downwardly extending latch 51 on its periphery, which latches the opening of the upper cylindrical body 12 (i.e., the edge of the top opening 103 of the bottle body 10), thus mounting the cap 50 on the top of the bottle body 10.

[0052] Specifically, see the attached document. Figure 5 , Figures 6 to 11 The outer wall of the upper cylindrical body 12 of the bottle body 10 has at least one fastening ring 121, and the fastening arm 51 of the cap body 50 has a fastening groove 511. The inner diameter of the fastening arm 51 of the cap body 50 is the same as the outer diameter of the opening of the upper cylindrical body 12. After the cap body 50 is installed at the opening of the upper cylindrical body 12 of the bottle body 10, the fastening ring 121 of the upper cylindrical body 12 extends into the fastening groove 511 of the fastening arm 51 of the cap body 50, so that the fastening arm 51 of the cap body 50 fastens the opening of the upper cylindrical body 12, thereby making the cap body 50 reliably installed on the top of the bottle body 10.

[0053] In this specific example of the rotating cream jar of this utility model, refer to the attached drawing. Figure 3 and Figure 4 The outer wall of the upper cylindrical body 12 has at least one set of protruding ribs 122 and at least one set of grooves 123, with a groove 123 formed between two adjacent protruding ribs 122. Correspondingly, the buckle arm 51 of the cover 50 has at least one set of protruding ribs 512 and at least one set of grooves 513, with a groove 513 formed between two adjacent protruding ribs 512. The protruding ribs 512 of the buckle arm 51 of the cover 50 protrude into the grooves 123 of the upper cylindrical body 12, and the protruding ribs 122 of the upper cylindrical body 12 protrude into the grooves 513 of the buckle arm 51. This prevents the cover 50 from rotating relative to the upper cylindrical body 12.

[0054] Continue to refer to the appendix Figure 9 , Figures 12 to 14The bottle body 10 includes at least one blocking arm 14, which extends from the inner wall of the bottom plate 11 defining the bottom perforation 102 of the bottle body 10 to the bottom perforation 102, i.e., the blocking arm 14 protrudes into the bottom perforation 102 of the bottle body 10. The lifting column 40 has at least one boss 42, which protrudes from the peripheral wall of the lifting column 40. During the assembly of the lifting column 40 to the bottle body 10, when the bottom of the lifting column 40 passes through the bottom perforation 102 of the bottle body 10, the lifting... The protrusion 42 of the lifting column 40 will press down on the blocking arm 14 of the bottle body 10, causing the blocking arm 14 to deform. After the bottom of the lifting column 40 passes through the bottom perforation 102 of the bottle body 10, the blocking arm 14 automatically returns to its initial state. At this time, the blocking arm 14 and the protrusion 42 of the lifting column 40 correspond in the height direction, and the projections of the blocking arm 14 and the protrusion 42 of the lifting column 40 on the horizontal plane have an overlapping part. In this way, the rotating cream bottle can prevent the lifting column 40 from falling off the bottle body 10.

[0055] In particular, in the appendix Figures 1 to 15 In this specific example of the rotating cream bottle of the present invention shown, the bottle body 10 includes two blocking arms 14 arranged face to face, and correspondingly, the lifting column 40 has two bosses 42 arranged back to back, and the two blocking arms 14 of the bottle body 10 and the two bosses 42 of the lifting column 40 correspond one-to-one.

[0056] Continue to refer to the appendix Figures 1 to 6 , Figures 9 to 11 The rotating cream bottle includes a bottom shell 60 with a bottom shell cavity 601. The bottom of the bottle body 10 extends into the bottom shell cavity 601 of the bottom shell 60, and the drive seat 30 is fixedly installed on the bottom shell 60. Thus, when the user rotates the bottom shell 60, the bottom shell 60 can drive the drive seat 30 to rotate relative to the bottle body 10.

[0057] Specifically, the outer wall of the driven cylinder 34 of the drive base 30 has a blocking ring 341, and the inner wall of the bottom shell 60 has a blocking ring 61. The blocking ring 61 of the bottom shell 60 is located above the blocking ring 341 of the driven cylinder 34. In this way, the blocking ring 61 of the bottom shell 60 can block the blocking ring 341 of the driven cylinder 34, preventing the bottom shell 60 and the driven cylinder 34 from separating from each other, thereby allowing the drive base 30 to be fixedly installed on the bottom shell 60. To prevent the driven cylinder 34 of the drive base 30 and the bottom shell 60 from rotating relative to each other, the driven cylinder 34 and the bottom shell 60 can be provided with the same structure as the buckle arm 51 of the upper cylinder 12 and the cover 50. This utility model will not elaborate further on this.

[0058] Reference Appendix Figure 1 , Figures 3 to 6 , Figure 10 The rotating cream jar includes a top shell 70 having a top shell cavity 701. The top shell 70 is detachably mounted to the bottom shell 60. When the top shell 70 is mounted to the bottom shell 60, the top of the bottle body 10 extends into the top shell cavity 701 of the top shell 70 to conceal the cap 50. After the top shell 70 is removed from the bottom shell 60, the cap 50 is exposed.

[0059] Reference Appendix Figure 10 The top shell 70 has an inner wall with a slot 71, and the bottom shell 60 has an outer wall with a protrusion 62. When the top shell 70 is installed on the bottom shell 60, the protrusion 62 of the bottom shell 60 engages with the slot 71 of the top shell 70, thus reliably installing the top shell 70 onto the bottom shell 60. Optionally, in other examples of the rotating cream bottle of this invention, the protrusion 62 may also be provided on the inner wall of the top shell 70, and correspondingly, the slot 71 may be provided on the outer wall of the bottom shell 60. When the top shell 70 is installed on the bottom shell 60, the protrusion 62 of the top shell 70 engages with the slot 71 of the bottom shell 60, thus reliably installing the top shell 70 onto the bottom shell 60.

[0060] Reference Appendix Figures 3 to 7 , Figure 9 and Figure 10 In this specific example of the rotating cream bottle of this utility model, the top of the lifting column 40 is mounted on the piston 20, so that the top of the lifting column 40 is positioned above the piston 20. That is to say, in the attached... Figures 1 to 15In this specific example of the rotating cream bottle of the present invention, the piston 20 and the lifting column 40 are separate components, which are installed together after being molded separately. Optionally, in other specific examples of the rotating cream bottle of the present invention, the piston 20 and the lifting column 40 may also be an integral structure.

[0061] Continue to refer to the appendix Figures 3 to 7 , Figure 9 and Figure 10 The piston 20 has an insertion arm 21 at its bottom and an insertion hole 43 at its top. The insertion arm 21 of the piston 20 is inserted into the insertion hole 43 of the lifting column 40, and the outer wall of the insertion arm 21 and the inner wall of the lifting column 40 that defines the insertion hole 43 engage with each other to mount the top of the lifting column 40 onto the piston 20.

[0062] Preferably, the piston 20 has at least one limiting groove 22 at its bottom, and the lifting column 40 has at least one limiting ear 44 at its top. The limiting ear 44 of the lifting column 40 is located in the limiting groove 22 of the piston 20. In this way, the piston 20 and the lifting column 40 will not rotate relative to each other. (See attached...) Figures 1 to 15 In this specific example of the rotating cream bottle of the present invention shown, the piston 20 has two limiting grooves 22, and correspondingly, the lifting column 40 also has two limiting ears 44. The two limiting ears 44 of the lifting column 40 and the two limiting grooves 22 of the piston 20 correspond one-to-one.

[0063] The specific usage process of the rotating cream bottle of this utility model is as follows: First, the top shell 70 is separated from the bottom shell 60 to expose the cap 50; second, the user holds the upper cylinder 12 of the bottle body 10 with one hand and rotates the bottom shell 60 in one direction with the other hand. The bottom shell 60 drives the drive seat 30 to rotate relative to the bottle body 10. The internal thread 31 of the drive seat 30 and the external thread 41 of the lifting column 40 cooperate with each other so that the drive seat 30 drives the lifting column 40 to rise relative to the bottle body 10. The lifting column 40 drives the piston 20 in the bottle cavity of the bottle body 10. The piston 20 carries the cream 100 upwards, and during this process, the cream 100 is squeezed out of the dispensing slot 501 of the cap 50, thus allowing the cream 100 to be dispensed. Then, when the user rotates the bottom shell 60 in the opposite direction, the piston 20 moves downwards within the cavity 101 of the bottle body 10, carrying the cream 100 downwards, thus drawing back the cream 100 that has entered the dispensing slot 501 of the cap 50. Subsequently, the user reattaches the top shell 70 to the bottom shell 60 to conceal the cap 50. In other words, in the rotating cream bottle of this invention, the user will not contaminate the cream 100 contained in the cavity 101 of the bottle body 10 during dispensing, thus avoiding contamination. Furthermore, the user can control the amount of cream 100 dispensed by controlling the rotation angle of the bottom shell 60.

[0064] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
