Description

Technical Field

[0001] The present invention relates to the field of packaging, and specifically to a screw-in type mixing container and its usage method, which are mainly used for the independent packaging, simultaneous storage, transportation, and mixed use of two materials. Background Art

[0002] Two-component packaging structures have been widely used in the field of cosmetic packaging. For example, Chinese Patent Document CN214691124U, which was published on November 12, 2021, discloses "a bottom-pushing type two-material combined bottle", including a bottle body with an open bottom end, a powder bin is arranged inside the bottle body, and also includes a lower cover and a powder bin cover; the powder bin cover is hermetically fixed at the open bottom end of the bottle body, and a powder bin cover guiding hole is penetrated through the powder bin cover; the powder bin includes a powder bin top wall above and a powder bin side wall on the side, and the bottom of the powder bin side wall is hermetically matched with the upper end surface of the powder bin cover; a powder bin guide rod extends downward from the powder bin top wall, and the powder bin guide rod is press-fitted through the powder bin cover guiding hole; a lower cover push rod extending upward is arranged at the corresponding position on the lower cover, and the upper end of the lower cover push rod overlaps the lower end of the powder bin guide rod; the lower cover can slide upward relative to the bottle body. The beneficial effect of the present utility model is: it can quickly and directly open the opening of the second material cavity to the maximum extent, so that the two materials are quickly mixed. In such traditional two-component mixing packaging structures, although the two components are separated and packaged, they have been assembled into one package at the time of factory, and consumers cannot freely match different components according to their own needs. For example, there are two types of a certain type of base oil, one suitable for dry skin and the other suitable for oily skin, and there are multiple types of efficacy agents such as acne removal, freckle removal, wrinkle removal, and whitening for use with the base oil. In the traditional structure, the manufacturer fixedly installs and matches one type of base oil and one type of efficacy agent in one package during canning, resulting in a very narrow adaptability of a single package, and it is very difficult for consumers to select a combination that is completely suitable for themselves. Products that are not selected by consumers often have difficulty in sales and cause expiration and waste. If the different formulations of these two components can be independently packaged, consumers only need to select a suitable independent base oil for themselves, then select an independent efficacy agent, and then through simple self-assembly, the problem of difficult selection can be easily solved, and the problem of difficult product sales can also be solved. Summary of the Invention

[0003] Based on the above problems, the present invention provides an upper bottle body and a lower bottle body that can be independently packaged, which can be used to independently package one of the materials respectively, and the double-bottle combined packaging structure formed by the upper bottle body and the lower bottle body can form a complete package, which can facilitate the mixing of the two materials.

[0004] Since all parts in this solution are coaxially installed, unless otherwise specified in the following text, the definitions of "axial direction", "radial direction", and "circumferential direction" for each part are the same.

[0005] To achieve the first invention object, the present invention adopts the following technical solution: A precessional mixing container, comprising an upper bottle body and a lower bottle body,

[0006] further comprising a lower cover of the upper bottle body;

[0007] The lower end of the upper bottle body is open; a diversion pipe is arranged inside the upper bottle body, the diversion pipe extends along the axial direction, the upper end is hermetically connected with the upper bottle body, and the height of the lower end is higher than the height of the opening at the lower end of the upper bottle body; a structure for axially upward limiting of the lower bottle body is arranged on the upper bottle body;

[0008] The lower bottle body has an upward opening, and a thread is arranged on the lower bottle body;

[0009] The lower cover of the upper bottle body is of an annular structure, the outer ring is hermetically sealed with the inner side wall of the upper bottle body, the inner ring is hermetically sealed with the diversion pipe, and the lower cover of the upper bottle body can slide up and down along the axis; a thread is arranged on the lower cover of the upper bottle body;

[0010] The thread arranged on the lower bottle body and the thread arranged on the lower cover of the upper bottle body form a mating thread connection.

[0011] Preferably, it further comprises a spiral driving part fixedly clamped with the lower cover of the upper bottle body; the spiral driving part is of an annular structure adapted to the size of the lower cover of the upper bottle body; the spiral driving part is provided with an internal thread, the lower bottle body is provided with an external thread, and the internal thread on the spiral driving part and the external thread arranged on the lower bottle body form a mating thread connection.

[0012] Preferably, an upper bottle body lower cover limiting ring is convexly arranged inward on the inner ring of the lower cover of the upper bottle body; when the lower cover of the upper bottle body is in the uppermost position, the upper end surface of the upper bottle body lower cover limiting ring and the lower end surface of the diversion pipe are axially limited to each other.

[0013] Preferably, a spiral driving part limiting ring is convexly arranged outward on the outer side wall of the spiral driving part, correspondingly, an upper bottle body inner side wall limiting ring is convexly arranged inward on the inner side wall of the upper bottle body, and the spiral driving part limiting ring and the upper bottle body inner side wall limiting ring form an axial limiting relationship.

[0014] Preferably, it further comprises a safety ring; the safety ring is arranged between the spiral driving part and the bottle shoulder of the lower bottle body; the height of the safety ring is not less than the effective height of the structure arranged on the upper bottle body for axially upward limiting of the lower bottle body.

[0015] Preferably, a sealing ring is arranged between the outer side wall of the outer ring of the lower cover of the upper bottle body and the inner side wall of the upper bottle body.

[0016] Preferably, the lower bottle body is provided with a lower bottle body sealing cover.

[0017] The structure of the upper bottle body designed in this technical solution is quite special. It not only has an opening at the upper end but also at the lower end. Moreover, a diversion pipe is connected inside the upper bottle body. The diversion pipe extends along the axis and is hermetically connected to the upper bottle body at the upper end, usually below the opening at the upper end of the upper bottle body, thus forming two concentric annular structures inside the upper bottle body. The outer layer is the side wall of the upper bottle body, and the inner layer is the diversion pipe. The space between the two structures is empty, sealed at the top and open at the bottom. At the same time, it is required that the bottom of the diversion pipe is higher than the height of the side wall of the upper bottle body.

[0018] The lower bottle body is used to store one of the two components of the dual-agent combination packaging in the mixing container and is equipped with a disposable lower bottle body sealing cap, which will be discarded before the consumer's first use. The lower bottle body is provided with an external thread, usually on the outer side of the side wall of the bottle mouth of the lower bottle body.

[0019] The lower cover of the upper bottle body is hermetically arranged between the side wall of the upper bottle body and the diversion pipe. The side wall of the upper bottle body, the diversion pipe, and the lower cover of the upper bottle body together form a sealed structure, which is the filling and storage space of the upper bottle body and is used to store the other of the two components of the dual-agent combination packaging in the mixing container.

[0020] Corresponding internal threads need to be designed on the lower cover of the upper bottle body to match the external threads provided on the lower bottle body. For the convenience of part manufacturing and assembly, a spiral driving part can be additionally designed and fixedly connected to the lower cover of the upper bottle body, and the internal threads are set on the spiral driving part. When the lower bottle body is in threaded cooperation with the spiral driving part, by turning the lower bottle body, the lower bottle body can be moved upward along the axis, or conversely, the spiral driving part can drive the lower cover of the upper bottle body to move downward along the axis. In the solution, the upper bottle body is provided with a structure that axially limits the upward movement of the lower bottle body, usually the axial limit between the lower end of the side wall of the upper bottle body and the bottle shoulder of the lower bottle body. Therefore, by turning the lower bottle body, the lower cover of the upper bottle body can be moved downward, and the sealing structure between the inner ring of the lower cover of the upper bottle body and the diversion pipe can be opened to realize the mixing of the two components.

[0021] The upper end face of the limiting ring of the lower cover of the upper bottle body and the lower end face of the diversion pipe are axially limited to each other, which can ensure the sealing effect of the independently filled upper bottle body during installation.

[0022] The limiting ring of the spiral driving part and the limiting ring of the inner side wall of the upper bottle body form an axial limiting relationship, which can ensure that when the lower bottle body is turned, the lower cover of the upper bottle body will not move downward excessively and come out of the lower opening of the upper bottle body.

[0023] The design of the sealing ring can improve the sealing effect between the lower cover of the upper bottle body and the inner side wall of the upper bottle body.

[0024] A single-use safety ring is placed between the screw drive and the shoulder of the lower bottle. After the upper and lower bottles are filled, the safety ring is installed and the upper and lower bottles are threaded together. With the safety ring in place, the screw drive cannot descend, preventing the seal between the inner ring of the upper bottle's lower cap and the flow tube from opening, ensuring safety during storage and transportation. During initial use, the consumer discards the safety ring and twists the lower bottle to open the seal between the inner ring of the upper bottle's lower cap and the flow tube.

[0025] The inner side wall of the upper bottle body can also be designed as a step shape, and the step surface can be used to form another axial limit for the lower cover of the upper bottle body. Other structures such as sealing gaskets and interference fits are conventional options in the field, and those skilled in the art can select and configure them as needed.

[0026] In this solution, the upper end opening of the upper bottle body can be used for pouring the mixed material normally. If the mixed material is liquid, a liquid collection mechanism such as a balloon-type liquid collection tube or an emulsion pump can also be installed at the upper end opening of the upper bottle body. The lower end of the liquid collection tube in the liquid collection mechanism can be extended downward along the guide tube to below the liquid surface.

[0027] In order to achieve the second object of the invention, the present invention adopts the following technical solution: the method for using the aforementioned screw-in mixing container comprises the following steps:

[0028] 1. Close the upper opening of the upper bottle body, turn it upside down, and point the lower opening of the upper bottle body upwards;

[0029] 2. Pour the first material between the inner side wall of the upper bottle body and the guide tube, and then install the lower cover of the upper bottle body and the spiral drive member between the inner side wall of the upper bottle body and the guide tube to seal;

[0030] 3. Pour the second material into the lower bottle body, and then seal the bottle mouth with the lower bottle body sealing cover;

[0031] 4. Place the safety ring on the screw drive; then screw the lower bottle body with the lower bottle body sealing cap to the screw drive; the filling stage is now complete;

[0032] 5. Unscrew the lower bottle body with the lower bottle body sealing cap in reverse direction, and remove the lower bottle body sealing cap to expose the bottle mouth of the lower bottle body;

[0033] 6. Remove the safety ring and turn the lower opening of the upper bottle downwards;

[0034] 7. Connect the lower bottle body to the screw drive through the thread;

[0035] 8. Continue to unscrew the bottle body. The threaded connection structure acts on the screw drive member, pulling the screw drive member and the lower cover of the upper bottle body downward until the seal between the lower cover of the upper bottle body and the guide tube is released.

[0036] IX. When the first material and the second material come into contact and are mixed, they can be taken out and used from the upper opening of the upper bottle body; thus, the preparation stage before the use of the mixed material ends, and then it can be taken out at any time.

[0037] As a person skilled in the art, the above-mentioned threaded connection structure can also be simply deformed: a sliding convex block is designed to protrude on the lower bottle body, and a spiral sliding groove is provided on the lower cover of the upper bottle body or a part fixedly connected thereto, and the sliding convex block is embedded in the sliding groove. Such a deformation can also achieve the effect of pulling the lower cover of the upper bottle body downward when the lower bottle body rotates relative to the upper bottle body, thereby releasing the seal.

[0038] In summary, the beneficial effects of this solution are as follows: the upper bottle body and the lower bottle body that can be independently packaged are provided, which can be used to independently package one of the materials respectively, and the double-bottle combined packaging structure formed by combining the upper bottle body and the lower bottle body can form a complete package, which is convenient for the mixing of the two materials; the lower cover of the upper bottle body cannot be opened alone and can only be opened after matching with the lower bottle body, so it is beneficial to the independent storage and transportation of the upper and lower bottle bodies; the opening process adopts a spiral structure, which is more labor-saving.

[0057] Embodiment

[0058] The embodiment is a screw-in type mixing container. Refer to Figure 1 , the screw-in type mixing container in this example includes two main components: an upper bottle body 1 and a lower bottle body 5

[0059] Both the upper and lower ends of the upper bottle body 1 are open. The upper end is a normal discharge port, which is closed by an inner cover 99. The main part of the upper bottle body 1 is cylindrical. A diversion tube 11 is also connected inside the upper bottle body 1. The diversion tube is a circular tube, extending along the axial direction, and the upper end is hermetically connected to the lower part of the upper opening of the upper bottle body 1, thereby forming two concentric annular structures inside the upper bottle body 1: the side wall of the upper bottle body 1 is the outer layer, and the diversion tube 11 is the inner layer, and the space between the two structures is empty. Among them, the height of the lower end of the diversion tube 11 is higher than the height of the lower end of the side wall of the upper bottle body 1

[0060] Refer to Figure 2 , the lower bottle body 5 has an upward opening, and an external thread is provided on the outer side of the bottle mouth side wall. The bottle mouth is provided with a lower bottle body sealing cap 6. The lower bottle body 5 in this example is a glass bottle, and the diameter is equal to the diameter of the lower opening of the upper bottle body 1. When matched with the upper bottle body 1, the lower end of the side wall of the upper bottle body 1 constitutes a limit for the upward movement of the upper bottle body 1 along the axis. The lower bottle body sealing cap 6 selected is a butyl rubber stopper

[0061] Refer to Figure 4 , Figure 5 , Figure 6, the upper bottle body 1 is provided with an upper bottle body lower cover 2 and a spiral driving member 3 inside. The upper bottle body lower cover 2 is of an annular structure, including three parts: an inner side wall, a top wall, and an outer side wall. The inner side wall forms a seal with the diversion pipe 11, and the outer side wall forms a seal with the inner side wall of the upper bottle body 1. Among them, two upper and lower sealing ring installation grooves 22 are provided on the outer side wall of the upper bottle body lower cover 2, and each is fitted with a sealing ring 7 to improve the sealing effect between the upper bottle body 1 and the inner side wall. The upper bottle body lower cover 2 can slide up and down axially. A part of the inner side wall of the upper bottle body lower cover 2 near the upper part protrudes inwardly to form a ring-shaped upper bottle body lower cover limiting ring 21, and the upper end surface of the upper bottle body lower cover limiting ring 21 abuts against the lower end surface of the diversion pipe 11 to form an axial limiting structure. The inner side wall of the upper bottle body 1 is stepped, and the stepped surface faces the upper end surface of the outer side wall of the upper bottle body lower cover 2, thus forming another axial limiting structure.

[0062] The spiral driving member 3 is also of an annular structure, with dimensions corresponding to those of the upper bottle body lower cover 2, and is fixed below the upper bottle body lower cover 2 by clamping. The spiral driving member 3 is provided with an internal thread, which forms a threaded connection with the external thread provided on the outer side wall of the bottle mouth of the lower bottle body 5. The spiral driving member 3 is further provided with a ring-shaped spiral driving member limiting ring 31 protruding outward, and at a position near the lower end of the inner side wall of the upper bottle body 1, a ring-shaped inner side wall limiting ring 13 of the upper bottle body protruding inwardly is provided. The spiral driving member limiting ring 31 and the inner side wall limiting ring 13 of the upper bottle body form an axial limiting relationship.

[0063] The inner side wall of the upper bottle body 1 is further provided with a ring-shaped state sensing ring 12 protruding inwardly. When the upper bottle body lower cover 2 and the spiral driving member 3 are at the uppermost end of the installation, the state sensing ring 12 is exactly located below the spiral driving member limiting ring 31. If the upper bottle body lower cover 2 and the spiral driving member 3 need to move downward, they will first cross the state sensing ring 12, and the feeling in the hand will be a feeling of breaking through an obstacle with relatively more force, which helps the user feel the current state.

[0064] A ring-shaped safety ring 4 is provided between the spiral driving member 3 and the bottle shoulder of the lower bottle body 5. The safety ring 4 is made of hard plastic to ensure that the axial distance between the lower bottle body 5 and the spiral driving member 3 cannot be shortened.

[0065] A ring-shaped sealing gasket 8 is also provided between the spiral driving member 3 and the upper end surface of the bottle mouth of the lower bottle body 5.

[0066] The usage method of a screw-in type mixing container in this embodiment includes the following steps:

[0067] First, close the upper opening of the upper bottle body 1, invert it, and make the lower opening of the upper bottle body 1 face upward. At this time, the state is as Figure 7 shown;

[0068] 2. Pour the first material between the inner side wall of the upper bottle body 1 and the flow guide tube 11, and then install the upper bottle body lower cover 2 and the spiral drive member 3 between the inner side wall of the upper bottle body 1 and the flow guide tube 11 to seal them;

[0069] 3. Pour the second material into the lower bottle body 5, and then seal the bottle mouth with the lower bottle body sealing cover 6;

[0070] 4. Place the safety ring 4 on the screw drive 3. Figure 8 As shown; then the lower bottle body 5 of the bottle mouth sealed by the lower bottle body sealing cap 6 is spirally connected to the spiral drive member 3; the filling stage is now completed;

[0071] 5. Unscrew the lower bottle body 5 with the lower bottle body sealing cap 6 in reverse, and remove the lower bottle body sealing cap 6 to expose the bottle mouth of the lower bottle body 5;

[0072] 6. Remove the safety ring 4 and turn the lower end of the upper bottle body 1 downward. Figure 9 As shown;

[0073] 7. Screw the lower bottle body 5 onto the screw drive 3 via threads;

[0074] 8. Continue to screw down the bottle body 5. The threaded connection structure acts on the screw drive member 3, pulling the screw drive member 3 and the upper bottle body lower cover 2 downward until the seal between the upper bottle body lower cover 2 and the guide tube 11 is released. At this time, the state is as follows: Figure 10 As shown;

[0075] 9. After the first material and the second material are in contact and mixed, they can be taken out from the upper opening of the upper bottle body 1 for use. Thus, the preparation stage before taking out the mixed material is completed, and the mixed material can be taken out at any time.
