Description

Technical Field

[0001] This utility model relates to the technical field of daily chemical product packaging, specifically a double-tube, double-material cream container. Background Technology

[0002] In the packaging of daily chemical products, for products that require the use of two different materials, the two materials are usually stored separately and then discharged simultaneously using a pump mechanism when in use.

[0003] In the prior art, there are already packaging devices that employ a dual-chamber and dual-pump structure. For example, patent publication number CN211167749U discloses a dual-tube integrated pump and a bottle containing it, which uses two pump tubes to extend into the left and right chambers respectively, and uses connecting tubes, support tubes, and pressing heads to lead out two streams of material. Another patent document, publication number CN214759629U, discloses a dual-tube emulsion bottle, which has two inner bottles set inside the outer bottle and two pressing pumps set on the shoulder sleeve, and realizes the discharge of two kinds of material through two inlet chambers in the inner cap and the same outlet.

[0004] The above structure enables the separate storage and simultaneous pumping of the two materials. However, in some structures, the two materials converge into the same area after entering the press head, connecting tube, inner cover, or common outlet. For creams and ointments that need to be kept as separate as possible before use, the two materials may come into contact in advance in the discharge area inside the packaging. This may cause the two materials to react before being pumped out, and mixed materials may remain in the common area after discharge, thus affecting the separation of the two materials when used again.

[0005] Therefore, it is necessary to provide a dual-tube, dual-material cream container, in which the two materials are stored separately in the tube and move along their respective independent discharge paths during pumping until they are discharged near the discharge end, so as to reduce the possibility of the two materials mixing prematurely inside the packaging. Utility Model Content

[0006] The purpose of this invention is to provide a dual-tube, dual-material cream container to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dual-tube, dual-material cream container, comprising a tube body and a pumping assembly, wherein two mutually isolated storage chambers are provided within the tube body; the pumping assembly is sealed to the openings of the two storage chambers, forming two pumping paths respectively connected to the two storage chambers; the pumping assembly includes a pressing and discharging component, which is connected to the two pumping paths and keeps the material in the two pumping paths isolated before reaching the discharging end of the pressing and discharging component.

[0008] Furthermore, the pressing and discharging component includes a first discharging section and a second discharging section. The first discharging section is connected to one of the pumping paths, and the second discharging section is connected to the other pumping path. The internal flow channels of the first discharging section and the second discharging section are isolated from each other.

[0009] Furthermore, the first discharge section and the second discharge section are respectively connected to the corresponding upper pistons, and each upper piston is respectively sealed to the opening of the corresponding storage chamber.

[0010] Furthermore, the pressing and discharging component includes a spring, which is respectively sleeved on the outer periphery of the first discharging part and the second discharging part.

[0011] Furthermore, silicone valves are respectively installed in the first discharge section and the second discharge section.

[0012] Furthermore, the first discharge section and the second discharge section are arranged at least partially overlapping, and their internal flow channels at the intersection are isolated from each other.

[0013] Furthermore, a partition wall is provided inside the tube, which divides the interior of the tube into two storage chambers.

[0014] Furthermore, it also includes a pump head cover, a discharge cover button, and a dust cover. The pump head cover is connected to the upper end of the tube body, the discharge cover button is movably disposed on the pump head cover, and the dust cover is disposed on the outside of the pump head cover and the discharge cover button. The discharge cover button has a pressing surface and a blocking part. When the pressing surface is pressed, the discharge cover button moves downward relative to the pump head cover and moves along an arc trajectory to drive the pressing discharge component to move downward and to make the blocking part allow the discharge end of the pressing discharge component to pass.

[0015] Furthermore, the shielding part has a scraping edge. After the external force is released, the discharge cover button is reset, and the scraping edge passes through the discharge end of the pressing discharge component to scrape the residual material at the discharge end, and the shielding part covers the discharge end.

[0016] Furthermore, it also includes a lower piston base, an anti-backward metal plate, and a lower piston, wherein the lower piston is disposed in the storage cavity, and the anti-backward metal plate is disposed between the lower piston base and the lower piston.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model forms two isolated storage chambers within the tube body, and the pumping assembly correspondingly forms two pumping paths. The first and second discharge sections of the pressing discharge component are respectively connected to the two pumping paths and remain isolated from each other before the discharge end. Thus, the two materials exist in independent spaces during storage and pumping, only converging after being discharged from the discharge end, reducing the possibility of premature contact, reaction, or mutual influence between the two materials inside the container. 2. In this utility model, the discharge cover button is movably mounted on the pump head cover. When the pressing surface of the discharge cover button is pressed, the discharge cover button moves downward and along an arc-shaped trajectory, causing the pressing discharge component to move downward and open the discharge end. After the external force is released, the discharge cover button resets and passes through the discharge end of the pressing discharge component to scrape the residual material at the discharge end before closing the discharge end. Therefore, it is not necessary to remove the discharge cover button during use, and resetting it can reduce the possibility of residual material at the discharge end being exposed, drying, or contaminating subsequent discharges. 3. This utility model uses two pumping paths, each with an independent upper piston, spring, and silicone valve. When the material is pressed down, the two material streams are pumped out by their respective pumping structures. After being released, they are reset by their respective springs. Each material stream has a relatively independent pumping and reset structure, resulting in more balanced force during discharge and more stable discharge status during continuous pressing.

[0020] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0021] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0022] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings. It should be understood that the following embodiments are only used to illustrate the structural composition and working process of this utility model, and are not intended to limit the protection scope of this utility model.

[0024] As shown in the attached diagram of the instruction manual. Figures 1-5 As shown, this embodiment provides a dual-tube, dual-material cream container, which includes a tube body 1, a pumping assembly 2, a pump head cover 3, a discharge cover button 4, a dust cover 5, a lower piston base 6, an anti-backward metal plate 7, and a lower piston 8. The tube body 1 is the main body of the container, and the pumping assembly 2 is installed at the upper end of the tube body 1. The material inside the tube body 1 is discharged outward through the pumping assembly 2.

[0025] Two isolated storage chambers 1b are formed inside the tube body 1. Please refer to the attached drawings in the instruction manual for details. Figure 2 The tube body 1 is provided with a partition wall 1a extending along the height direction of the tube body 1. The partition wall 1a divides the interior of the tube body 1 into two storage chambers 1b, which respectively contain different cream materials.

[0026] The two storage chambers 1b are separated by a partition wall 1a, and the material will not flow between them within the tube 1. Alternatively, the two storage chambers 1b can also be formed by two independent bottles or liners, which are assembled inside the tube 1 and sealed to the pumping assembly 2 respectively. As long as the two storage chambers 1b remain isolated from each other during the storage stage, the structural requirements of this solution can be met.

[0027] The pumping assembly 2 is located at the openings of the two storage chambers 1b, and the pumping assembly 2 corresponds to the two storage chambers 1b respectively, forming two pumping paths between the two storage chambers 1b and the pressing and discharging component 2d.

[0028] The two pumping paths receive the material from the corresponding storage chamber 1b and remain isolated before reaching the discharge end of the pressing discharge piece 2d, so that the two materials do not mix prematurely during the conveying process inside the container.

[0029] In the attached diagram of the instruction manual Figure 3 and Figure 4 In the pumping assembly 2, there are an upper piston 2a, a spring 2d3, a silicone valve 2b, and a pressing discharge component 2d. The two storage chambers 1b correspond to a set of pumping structures, and the upper piston 2a in each set of pumping structures is sealed to the opening of the corresponding storage chamber 1b.

[0030] The upper piston 2a and the opening of the storage chamber 1b form a close fit. When the material is pressed out, the material enters the corresponding pumping path from the corresponding storage chamber 1b, and does not leak out from the opening between the upper piston 2a and the storage chamber 1b.

[0031] The pressing and discharging component 2d is located on the upper part of the pumping assembly 2. The pressing and discharging component 2d includes a first discharging section 2d1 and a second discharging section 2d2. The first discharging section 2d1 is connected to one of the pumping paths, and the second discharging section 2d2 is connected to the other pumping path.

[0032] The first discharge section 2d1 and the second discharge section 2d2 can be tubular structures or channel structures formed within the pressing discharge member 2d; their internal flow channels are separated from each other. Figure 3 and Figure 4 In the illustrated embodiment, the first discharge section 2d1 and the second discharge section 2d2 are arranged at least partially intersecting or close to each other so that the discharge ends of the two material streams are adjacent, but they are still separated by their respective pipe walls or channel walls at the intersection or close positions.

[0033] Silicone valves 2b are respectively installed in the first discharge section 2d1 and the second discharge section 2d2. When the discharge cover button 4 moves the pressing discharge component 2d downward, the material in the corresponding pumping path pushes open the silicone valves 2b and enters the first discharge section 2d1 and the second discharge section 2d2 respectively. After the external force is released, the silicone valves 2b reset, reducing the backflow of material near the discharge end. Springs 2d3 are respectively sleeved on the outer periphery of the first discharge section 2d1 and the second discharge section 2d2. After the pressing discharge component 2d is pressed down, the springs 2d3 are compressed. After the external force is released, the springs 2d3 push the pressing discharge component 2d and the corresponding pumping structure back to the initial position.

[0034] Furthermore, in a preferred embodiment, the first discharge section 2d1 and the second discharge section 2d2 are each formed by at least two detachably connected pipe sections. Taking the first discharge section 2d1 as an example, a pipe section near the storage chamber 1b and a pipe section near the discharge end are interlocked or snapped together, and the two pipe sections together form the internal flow channel of the first discharge section 2d1. The second discharge section 2d2 can also adopt the same structure, with a silicone valve 2b disposed between the two pipe sections of the corresponding discharge section. After the two pipe sections are connected, they clamp or limit the silicone valve 2b, keeping it within the corresponding flow channel. When the silicone valve 2b needs to be replaced, the two pipe sections of the corresponding discharge section can be disassembled, the original silicone valve 2b can be removed, a new silicone valve 2b can be reinstalled, and then the two pipe sections can be reconnected.

[0035] To ensure stable reinstallation after disassembly, a mating spigot and socket can be installed between the two pipe sections. After the spigot extends into the socket, the internal flow channels of the two pipe sections are aligned. Simultaneously, the mating surfaces of the spigot and socket press against the edge of the silicone valve 2b, ensuring that the silicone valve 2b remains in its original flow channel position after reassembly. The first discharge section 2d1 and the second discharge section 2d2 can be disassembled and assembled independently, and their internal flow channels remain isolated from each other before and after disassembly.

[0036] The pump head cover 3 is installed at the upper end of the pipe body 1 and surrounds the outside of the pumping assembly 2. The pump head cover 3 constrains the installation position of the pumping assembly 2, so that the pumping assembly 2 is stably held at the opening of the two storage chambers 1b.

[0037] The discharge cover button 4 is movably mounted on the pump head cover 3 and covers the outside of the discharge end of the pressing discharge component 2d. The discharge cover button 4 has a pressing surface 4a for pressing with a finger and a blocking part 4b corresponding to the discharge end of the pressing discharge component 2d.

[0038] When not pressed, the blocking part 4b is located outside the discharge end of the first discharge part 2d1 and the second discharge part 2d2 to block the discharge end; when the pressing surface 4a is pressed, the discharge cover button 4 moves downward and along the arc trajectory under the limiting cooperation of the pump head cover 3, the blocking part 4b moves away from the discharge end with the discharge cover button 4, and at the same time the discharge cover button 4 drives the pressing discharge part 2d to move downward.

[0039] The dust cover 5 is installed on the outside of the pump head cover 3 and the discharge cover button 4. When the container is not in use, the dust cover 5 covers the upper discharge structure.

[0040] The lower piston 8 is located inside the storage chamber 1b and below the material. As the material in the storage chamber 1b is gradually pumped out, the lower piston 8 moves upward as the material decreases, thus maintaining support for the material in the storage chamber 1b.

[0041] The lower piston base 6 is located at the lower part of the tube body 1, and the anti-backward metal plate 7 is disposed between the lower piston base 6 and the lower piston 8.

[0042] When the anti-backward metal plate 7 cooperates with the lower piston 8, it restricts the lower piston 8 from retracting downward, reducing the suction or discontinuous discharge caused by the lower piston 8 falling back during use.

[0043] Workflow: When using, first remove the dust cover 5; there is no need to remove the discharge cover button 4. Press the pressing surface 4a of the discharge cover button 4 with your finger. The discharge cover button 4 moves downwards and along an arc-shaped trajectory. The blocking part 4b clears the previously blocked discharge end, and simultaneously, the discharge cover button 4 drives the pressing discharge component 2d to move downwards. After the pressing discharge component 2d moves downwards, the two pumping paths draw material from the corresponding storage chamber 1b; one path of material enters the first discharge section 2d1, and the other path enters the second discharge section 2d2. Because the internal flow channels of the first discharge section 2d1 and the second discharge section 2d2 are isolated from each other, the two materials will not mix prematurely during pumping and before discharge. After releasing the discharge cover button 4, the spring 2d3 pushes the pressing discharge component 2d to reset, and the silicone valve 2b returns to the closed state.

[0044] When the discharge part 2d is pressed to reset, the discharge cover button 4 returns to its initial position. During the reset process of the discharge cover button 4, the blocking part 4b passes through the discharge end of the discharge part 2d, and the scraping edge 4c on the blocking part 4b scrapes the residual material at the discharge end. Then the blocking part 4b closes the discharge end again, and the lower piston 8 gradually moves upward in the storage chamber 1b as the material is consumed. The anti-reverse metal plate 7 restricts the retraction of the lower piston 8, so that material can still be continuously extracted when pressed later.

[0045] In this embodiment, the partition wall 1a forms two storage cavities 1b as shown in the diagram; in other embodiments, the two storage cavities 1b can also be formed by two independent bottles, two independent inner liner, or other isolation structures. Accordingly, the pumping assembly 2 only needs to be sealed and fitted with the openings of the two storage cavities 1b respectively, and keep the two material streams isolated from each other before reaching the discharge end of the pressing discharge member 2d, to achieve dual-cavity storage and dual-path discharge.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
