Description

Technical Field

[0001] The present invention relates to a mixing spray device and method, and more particularly, to a device and method capable of mixing and injecting a solid content and a liquid material with each other.

Background Art

[0002] Cosmetic containers vary in form and material type due to the diversification, personalization, and technological progress of consumers. Cosmetics vary in container type, form, and shape depending on their respective uses and dosage forms.

[0003] Cosmetics, that is, the contents contained in cosmetic containers, are classified into five parts: perfume, eau de cologne, hair cosmetics, skin cosmetics, makeup cosmetics, and special-purpose cosmetics. Cosmetic containers for containing these cosmetics aim to protect the contents during the production of the contents, guarantee the quality of the contents until consumers purchase them through packaging, distribution storage, and sales stores and until the use is completed.

[0004] Due to the changes of the times, cosmetic containers have led to the development of new containers with higher functionality and higher added value through the era of original personalization and diversification of design and fashionability. Therefore, from the perspective of global environmental protection, elements friendly to the environment and the functional aspect of guaranteeing the quality of the contents are emphasized for cosmetic containers.

[0005] As a method for designing cosmetic containers, it is necessary to have social compatibility and economic efficiency in line with the development of new materials and the innovation of new processing technologies based on their important functions such as protection, stability, convenience, and information transmission.

[0006] Pumps, a type of cosmetic container, are classified into airless pumps, dispenser pumps, dropper pumps, mist pumps, and well pumps. Aerosol containers, distinct from pumps, use a system where the contents and liquefied or pressurized gas are placed in the container and the contents are sealed with a valve button. Aerosol containers are used for foam hair products and hairsprays, where the contents are discharged with a button click into a spray phase, bubble phase, etc.

[0007] Cosmetics, which are made through a process of mixing various ingredients, often suffer from altered properties due to chemical reactions between ingredients, resulting in a decrease in their functional effectiveness as cosmetics. Examples include cosmetics containing vitamins or dyes. To address these problems, research is actively progressing on cosmetic containers designed to hold different substances.

[0008] As a technology related to the present invention, a technology relating to a container for mixing different substances, disclosed in the Registered Patent Publication of the Republic of Korea, discloses an apparatus and method for discharging separated contents from an inner container using a first pump set and a second pump set. This related technology is distinguished from the present invention, which targets solids, in terms of configuration and effect, by using two pump sets for two types of liquids and one pump set.

[0033] Figure 1 is an illustrative diagram of a mixing spray according to one embodiment of the present invention. Referring to Figure 1, a mixing spray device 100 according to one embodiment of the present invention can be configured to include a housing 110 and a main body 101 (not shown) provided within the housing 110. The power switch 181, LED indicator 182, and speaker 183 that constitute the rface 180, and the discharge button 171 and nozzle 172 that constitute the external discharge section 170 are provided on the outer surface of the housing 110. The following describes the housing 110 and the main body 101 of the mixing spray device 100.

[0034] Figure 2 is an exploded view of the main body and housing of a mixing spray device according to one embodiment of the present invention. Referring to Figure 2, the mixing spray device 100 is disassembled into a housing 110 and a main body 101. Multiple covers can be assembled to constitute the overall housing 110. The housing 110 can be configured to include a head cover 111, a middle cover 116, and a bottom cover 118. The middle cover 116 is separated into a front cover and a rear cover. The bottom cover 118 can be composed of multiple parts that can be opened and closed depending on the type of battery.

[0035] The user interface 180 is positioned on the head cover 111. The head cover 111 can be connected to the middle cover 116 in a way that allows it to be opened and closed. The connection between the head cover 111 and the middle cover 116 will be described later.

[0036] Figure 3 is an exploded view of the right side of the main body of a mixing spray device according to one embodiment of the present invention. Referring to Figure 3, the main body 101 of the mixing spray device 100 can be configured to include a container section 130, an internal discharge section 150, a mixing section 160, an external discharge section 170, and a power supply section 190. The power supply section 190 can be configured to include a PCB assembly 191 and a battery assembly 195. The PCB assembly 191 and the battery assembly 195 are electrically connected to each other. The PCB assembly 191 is electrically connected to the internal discharge section 150 and the mixing section 160.

[0037] The components of the container section 130, the internal discharge section 150, the mixing section 160, and the external discharge section 170 are connected to each other or can be connected to the housing 110 in an efficient position within the housing 110 to perform a series of interconnected processes, such as storing the contents, internally discharging the contents, mixing the contents, and externally discharging the mixture.

[0038] For example, the internal discharge section 150 is positioned to be in contact with the top of the container section 130 in order to pressurize the container section 130 and discharge its contents. The container section 130 is positioned between the internal discharge section 150 and the mixing section 160 in order to receive pressure from the internal discharge section 150 and discharge its contents downwards. The mixing section 160 is positioned below the container section 130 to collect the contents discharged from the container section 130.

[0039] Figure 4 is an illustrative diagram of the internal discharge section of a mixing spray device according to one embodiment of the present invention. Referring to Figures 3 and 4, the internal discharge section 150 is located at the top of the container section 130 and is in contact with the first cartridge 132 and the second cartridge 140 of the container section 130. It has the function of pushing the cartridges 132 and 140 to discharge the contents stored in the first container 133 and the second container 141 of the container section 130 into the housing 110, i.e., into the mixing chamber 161. The internal discharge section 150 can be configured to include a pressurizing section 151, a pressure transmission section 155, and restoring springs 156 and 157.

[0040] The pressurizing section 151 is fixed within the housing 110, for example, to the PCB bracket 194. The pressure transmission section 155 is in contact with the pressurizing section 151 on one side and with the container section 130 on the other side. The pressure transmission section 155 receives pressure from the pressurizing section 151, pressurizes the container section 130, moves forward, and when released from the pressurizing section 151, is returned to its original position by the action of the return springs 156 and 157. The pressurizing unit 151 has the function of generating pressure through a cam 154 connected to the motor assembly 152 by rotating the motor of the motor assembly 152 in response to the operation of the power switch 181.

[0041] The pressure transmission unit 155 has the function of transmitting the pressure generated by the cam 154 included in the pressurizing unit 151 to the container unit 130. The pressure transmission unit 155 can be configured to move forward and backward within the housing 110. When the pressure from the pressure transmission unit 155 is transmitted to the container unit 130, a certain amount of the contents stored in the cartridge 131 is discharged into the mixing chamber 161. The restorer springs 156 and 157 have the function of restoring the cartridge 131, which has been pushed by the pressure from the pressure transmission unit 155, to its correct position.

[0042] The PCB assembly 191 constituting the power supply unit 190 can be configured to be coupled to the housing 110. In particular, the pressure transmission unit 155 constituting the internal discharge unit 150 is configured to be movable up and down via return springs 156 and 157, so that the lower part of the pressure transmission unit 155 is coupled to the return springs 156 and 157 with the head cover bottom surface 112, and the upper part of the pressure transmission unit 155 can be slidably coupled to a fixed shaft, for example, the PCB bracket 194 of the PCB assembly 191.

[0043] Figure 5 is an illustrative diagram of the container section, mixing section, and external discharge section of a mixing spray device according to one embodiment of the present invention. Referring to Figure 5, the container section 130 can be configured to include a cartridge 131 and a cartridge cover 139. The cartridge 131 may include a first cartridge 132 and a second cartridge 140. The first cartridge 132 and the second cartridge 140 can store different contents 10 in a separated state. For example, the first cartridge 132 can store liquid contents, and the second cartridge 140 can store solid contents.

[0044] The cartridge 131 can be configured to be separable from and connectable to the cartridge cover 139. Therefore, the cartridge 131 is a consumable item and is replaceable. The mixing section 160 can be connected to the housing 110 and configured to be located at the bottom of the container section 130. Therefore, the contents discharged (internal discharge) from the container section 130 fall into the mixing section 160 for temporary storage. The mixing section 160 can be configured to include a mixing chamber 161, a mixing motor 162 located at the top of the mixing chamber 161 and electrically connected to the PCB assembly 191, and a screw 163 connected to the mixing motor 162 and located inside the mixing chamber 161. The mixing unit 160 can be configured such that a mixing motor 162 is driven by a PCB assembly 191, and a screw 163 coupled to the mixing motor 162 rotates, mixing the contents 11 and 12 stored in the mixing chamber 161 to form a mixture 20.

[0045] The external discharge unit 170 may be configured to include a discharge button 171 that transmits the user's grip pressure, a nozzle 172 from which the mixture is ejected, a pump 173 that provides air pressure to draw in the mixture, and a hose 174 that draws in the mixture stored in the mixing chamber 161. A discharge button 171 is provided exposed to the outside of the housing 110 so as to pressurize the pump 173. A nozzle 172 is provided at one end of the pump 173 so as to be exposed to the outside through a hole provided in the housing 110. The pump 173 can be configured so that the output side is connected to the nozzle 172 and the input side is connected to a hose 174. The hose 174 is connected to the other end of the pump 173 and positioned above the mixing chamber 161.

[0046] Pump 173 can be selected from a group of pumps configured in various ways. Pump 173 is also an air pump that can spray a mixture of solid and liquid contents in the form of a mist.

[0047] The user's grip pressure presses the discharge button 171, which activates the pump 173. The suction action of the pump 173 causes the mixture in the mixing chamber 161 to be ejected through the hose 174 and the nozzle 172 to the outside of the housing 110. The external discharge section 170 can be connected to the housing 110 and configured so that a portion of it overlaps with the mixing section 160. That is, one end of the external discharge section 170 is inserted into the mixing section 160 so that it can draw in the mixture stored in the mixing section 160.

[0048] Figure 6 is a cross-sectional view of a mixing spray apparatus according to one embodiment of the present invention. Referring to Figure 6, the mixing spray device 100 has a head cover 111 that is the middle section of the pressure transmission section 155 and the container section 130 that constitute the internal discharge section 150, with the boundary (a-a') between them. The head cover 111 can be configured to be partially separated from the bar 116. That is, the head cover 111 and the middle cover 116 can be connected via a hinge joint, and the head cover 111 can be opened and closed relative to the middle cover 116.

[0049] Inside the head cover 111 are the PCB assembly 191 and the internal discharge section 150, which includes the pressurizing section 151 and the pressure transmission section 155. Inside the middle cover 116 are the container section 130, the mixing section 160, the external discharge section 170, and the battery assembly 195.

[0050] Figure 7 is an illustrative diagram of a cartridge replacement structure for a mixing spray device according to one embodiment of the present invention. Referring to Figure 7, the connection between the head cover 111 and the middle cover 116 is depicted. The head cover 111 and the middle cover 116 can be connected to each other through a hinge 113 on the back and a connecting part 114 on the front. When the connecting part 114 separates from the middle cover 116, the head cover 111 rotates away from the middle cover 116 around the hinge and opens. Conversely, the head cover 111 closes as the connecting part 114 remains connected to the middle cover 116.

[0051] The coupling portion 114 is the front portion of the housing 110 where the bottom surface 112 of the head cover and the top surface of the middle cover 116 come into contact with each other, and can be configured to include magnetic material pairs 115 and 117 for coupling. The coupling between the head cover 111 and the middle cover 116 is made firm and the coupling action is induced through coupling / separation via the magnetic force between the upper first magnetic material 115 and the lower second magnetic material 117. At least one of the upper first magnetic material 115 and the lower second magnetic material 117 is also a magnet.

[0052] Figure 8 is an exploded view of the container section of a mixing spray device according to one embodiment of the present invention. Referring to Figure 8, the container section 130 can be configured to include a cartridge cover 139 that connects to the housing 110 and a cartridge 131 that can connect to and separate from the cartridge cover 139. That is, the cartridge 131 is a consumable item and can be separated and replaced from the cartridge cover 139 after the head cover 111 is opened by the middle cover 116, as shown in Figure 7.

[0053] Figure 9 is an illustrative diagram of a cartridge for a mixing spray device according to one embodiment of the present invention. Referring to Figure 9, cartridge 131 can be configured to include a first cartridge 132 and a second cartridge 140. The first cartridge 132 and the second cartridge 140 can store contents of different components. For example, the first cartridge 132 can be configured to store a first liquid content 11, and the second cartridge 140 can be configured to store a second solid content 120.

[0054] The first cartridge 132 may be configured to include a first container 133 and a first discharge section 134 connected to the first container 133. The first container 133 has the function of storing the first contents 11 and descending under pressure from the internal discharge section 150. As the first container 133 descends under pressure from the internal discharge section 150, the first discharge section 134 has the function of receiving pressure from the first container 133 and discharging the first contents 11 from the first container 133 to the mixing section 160.

[0055] The second cartridge 140 can be configured to include a second discharge section 144 which is connected to the second container 141, a screw feeder 142, and a screw feeder 142, and which receives pressure from the second container 141 to rotate the screw feeder 142 and discharge the second contents from the second container 141. The second container 141 stores the second contents 12 and has the function of descending when pressure is received from the internal discharge section 150. As the second container 141 descends when pressure is received from the second discharge section 144, the second discharge section 144 has the function of receiving pressure from the second container 141 and discharging the second contents 12 from the second container 141 to the mixing section 160. The first container 133 and the second container 141 can have various shapes, such as cylinders, triangular prisms, quadrilateral prisms, and polygonal prisms.

[0056] Figure 10 is an exploded view of the main body of a mixing spray device according to one embodiment of the present invention. Referring to Figure 10, the motor assembly 152, cam 154, and pressure transmission unit 155 that constitute the internal discharge unit 150 are depicted. The components of the container unit 130, to which the pressure generated by the cam 154 is transmitted by the pressure transmission unit 155 are also depicted. The pressure transmission unit 155 is positioned above the first container 133 and the second container 141 to pressurize the first container 133 and the second container 141.

[0057] The first discharge section 134 may be configured to include a first upper module 135 that adjusts the opening and closing of the first container 133, a first middle module 136 that is coupled to the first upper module 135, a first lower module 138 that is coupled to the first middle module 136 so as to slide as the first container 133 descends and pressurizes the first upper module 135 so that the first contents 11 are discharged from the first container 133, and a first elastic body 137 that restores the position of the first container 133.

[0058] When the pressure from the internal discharge section 150 is transmitted to the container section 130, and the first lower module 138 rises relative to the first middle module 136 while pressurizing the first upper module 135, the liquid stored in the second container 141 is discharged into the mixing chamber 161 of the mixing section 160.

[0059] The second discharge section 144 can be configured to include a second upper module 145 that discharges the second contents 12 by the rotation of the screw feeder 142, a second middle module 146 coupled to the second upper module 145, a second lower module 148 that is coupled to the second middle module 146 so as to slide with the descent of the second container 141 and receives pressure from the second container 141 to rotate the screw feeder 142, and a second elastic body 147 that restores the position of the second container 141.

[0060] A screw feeder 142 is provided, passing through the second upper module 145 and the second lower module 148. The pressure from the internal discharge section 150 is transmitted to the container section 130, and as the second middle module 146 descends relative to the second lower module 148, the screw feeder 142 rotates, causing the second contents 12 stored in the second container 141 to fall and be discharged into the mixing chamber 161 of the mixing section 160.

[0061] The rotational or reversing motion of the screw feeder 142 creates a gap between the second lower module 148 and the hemispherical plug 149 formed at the end of the screw feeder 142, which then fills the gap, causing intermittent discharge of the second contents 12. A rubber packing or the like may be provided in the central hole of the second lower module 148 that contacts the plug 149. The first elastic body 137 and the second elastic body 147 have the function of inserting between the middle module and the lower module and raising the first container 133 and the second container 141, which have been lowered, back to their upright positions.

[0062] The first contents 11 stored in the first container 133 are liquid. The second contents 12 stored in the second container 141 are solid. The liquid and solid discharged from each container are mixed together in the mixing unit 160. In this case, the discharge volume and mixing ratio of the contents are determined by the pressure applied by the internal discharge unit 150 to the first container 133 and the second container 141. Therefore, a calibration process is necessary to determine various combinations of discharge volume and mixing ratio by varying the torque of the motor assembly 152 included in the internal discharge unit 150, the shape and size of the cam 154, and the clearance with the pressure transmission unit 155. Furthermore, even after the shape, size, and clearance of the cam 154 have been determined, the torque of the motor assembly 152 is adjusted by software (or middleware). Therefore, through firmware updates or modifications, users can determine the discharge amounts of the first contents 11 and the second contents 12, as well as their mixing ratio, to suit their personal preferences.

[0063] Figure 11 is a cross-sectional view of Figure 9. Referring to Figures 9 and 11, the lower surface of the cross section (b-b') depicted in Figure 9 is shown. It is. The first lower module 138, contained in the first cartridge 132 and having a cross-shaped cross-section in the center, pressurizes the first upper module 135, causing the liquid contents to flow out of the first container 133 and be discharged into the mixing chamber 161 of the mixing unit 160. The screw feeder 142 contained in the second cartridge 140 rotates through the action of the second lower module 148 and the second middle module 146, and through this rotation, the solids stored in the second container 141 are discharged into the mixing chamber 161 of the mixing unit 160. The first elastic body 137 has the function of returning the first container 133 to its correct position, and the second elastic body 147 has the function of returning the second container 141 to its correct position.

[0064] Figure 12 is a partial perspective view showing the bottom surface of the container. Referring to Figure 12, the bottom surface of the first lower module 138 of the first cartridge 132 is depicted in a partial perspective on the right. The bottom surface of the second lower module 148 of the second cartridge 140 is depicted in a partial perspective on the left. A first discharge hole 143 may be formed at the bottom of the first lower module 138 in the first cartridge 132 on the right side. As the first upper module 135 is opened by the first lower module 138, the first contents 11 are discharged through the first discharge hole 143 formed in the bottom surface of the first lower module 138.

[0065] The second cartridge 140 on the left depicts the second upper module 145, the second middle module 146 which connects to the second upper module 145, the second lower module 148 which connects to the second middle module 146, the second elastic body 147 which is inserted between the second middle module 146 and the second lower module 148, and the screw feeder 142 which connects the second middle module 146 and the second lower module.

[0066] The second upper module 145 has the function of discharging the second contents 12 by the rotation of the screw feeder 142. The second middle module 146 has the function of receiving pressure from the second container 141, descending, and rotating the screw feeder 142. The second lower module 148 is coupled to the second middle module so as to slide against it and has the function of intermittently discharging the second contents 12 by the rotation of the screw feeder 142. The discharge of the second contents 12 is intermittently caused by a hemispherical plug 149 formed at the end of the screw feeder 142 intermittently discharging a hole formed in the center of the second lower module 148. To prevent oxidation of the second contents 12, a rubber packing may be formed in the hole of the second lower module 148. The second elastic body 147 is inserted between the second middle module 146 and the second lower module 148 and has the function of restoring the position of the second container 141.

[0067] Figure 13 is a circuit diagram of a mixing spray device according to one embodiment of the present invention. Referring to Figures 3 and 13, the mixing spray apparatus 100 according to one embodiment of the present invention is characterized in that the power supply unit 190 includes a PCB assembly 191 and a battery assembly 195.

[0068] The PCB assembly 191 can be configured to include PCBs 192 and 193 containing various drive circuits and control circuits, and PCB brackets 194 for fixing the PCBs. The battery assembly 195 is electrically connected to PCBs 192 and 193 to supply circuit drive power to PCBs 192 and 193. The battery assembly 195 can be configured to include a battery and a battery case. Dry cell batteries or rechargeable batteries can be used as the battery. A USB terminal for charging the rechargeable battery is included in the user interface. In addition, the mixing spray device 100 can be connected to a computer via the USB terminal, allowing for adjustment of the discharge amount and mixing ratio of the first contents 11 and the second contents, as well as firmware updates.

[0069] The user interface 180 can be configured to include a power switch 181, an LED indicator 182, and a speaker 183. The mixing spray device 100 can be configured to include a motor assembly 152 for the internal discharge section 150 and a mixing motor 162 for the mixing section 160. The components of the user interface 180, the motor assembly 152, and the mixing motor 162 are electrically connected to various drive circuits and control circuits included in PCBs 192 and 193, and can receive drive power and control signals from the various drive circuits.

[0070] When the user presses the power switch 181, the mixing spray device 100 operates. With the power on, the mixing spray device 100 completes the operation of producing the mixture into the mixing chamber 161 through the operation of the internal discharge unit 150, the container unit 130, and the mixing unit 160. In this case, the mixing spray device 100 indicates the status of the mixing spray device 100, i.e., that the mixture 20 is ready, using at least one of the LED indicator 182 and speaker 183 of the user interface.

[0071] Furthermore, at least one of the LED indicator 182 and the speaker 183 can be configured to indicate, through light or sound, that the mixture is waiting to be discharged if it has not been discharged from the mixing chamber 161 to the outside of the housing 110. That is, if the mixture is not discharged after a certain period of time following the discharge waiting period, the user interface 180 will indicate that it is waiting to be discharged by changing the color of the light or by sound.

[0072] The method for detecting that the mixture 20 has not been discharged and is still in a discharge waiting state is to use a sensor to determine whether or not the discharge button 171 has been clicked, or to determine whether or not the mixture 20 is present in the mixing chamber 161. The external discharge unit 170 is activated by the user's grip pressure, and the mixed liquid from the mixing chamber 161 is ejected through the nozzle 172.

[0073] A mixing spray device 100 according to one embodiment of the present invention has the function of simultaneously discharging two different types of first contents 11 and second contents 12 into a mixing chamber 161 inside the housing 110, and spraying the mixture 20 generated through the operation of the mixing unit 160 to the outside through the operation of the external discharge unit 170. In particular, the external discharge operation is possible without electric power.

[0074] Thus, according to one embodiment of the present invention, different substances are mixed and discharged without alteration of each component. Furthermore, the solid and liquid components of the contents are dispensed separately in the amount appropriate for a single use. Furthermore, the solid and liquid components of the contents are uniformly mixed and discharged. Furthermore, different substances are mixed together in single-use quantities, and the entire mixed mixture is discharged at the time of each use. Furthermore, the user will be informed that the mixture generated during the mixing process has not been discharged.
