Abstract
Description
[Technical Field]
[0001] The present invention relates to a container and a content injection system that includes a valve unit having a plurality of stems, a storage section having the valve unit attached to its mouth, and an actuator attached to the plurality of stems. [Background technology]
[0002] Conventionally, a container equipped with a valve unit having a stem is known, for example, as a container (child container 120) configured to be able to be filled with contents (content liquid F) from a parent container (110) of a refill aerosol system described in Patent Document 1.
[0003] The container (child container 120) known in Patent Document 1 is fitted with a valve unit (child valve unit 121) having a stem (child stem 122), and is configured so that the contents (content liquid F) can be filled into a child inner bag (123) inside the container (child container 120), and a child container side propellant (CG) is pre-filled between the container (child container 120) and the child inner bag (123).
[0004] An actuator (child actuator 130) is attached to the stem (child stem 122), and the actuator (child actuator 130) has a stem fitting portion (133) at the bottom into which the stem (child stem 122) can be fitted, and a parent stem connection portion (136) at the top into which the first parent stem (112) of the parent container (110) can be connected, the stem fitting portion (133) and the parent stem connection portion (136) are connected by a transfer filling flow path (132), and the child actuator 130 further has an injection flow path (131) that branches off from the middle of the transfer filling flow path (132) and extends, and the other end of the injection flow path (131) is open. Furthermore, the actuator (child actuator 130) has an injection flow path blocking plug (134) and a transfer filling flow path blocking plug (135) that can block the injection flow path (131) and the transfer filling flow path (132), respectively, and by blocking either the injection flow path (131) or the transfer filling flow path (132), the contents (content liquid F) can be passed through the other unblocked flow path.
[0005] This allows the injection flow path (131) to be blocked with the injection flow path blocking plug (134), the first parent stem (112) to be connected to the injection port (parent stem connection part 136) with the injection port (parent stem connection part 136) open, and the parent container (110) to be pushed toward the container (child container 120), so that the contents (content liquid F) can be filled into the child inner bag (123) from the stem (child stem 122) of the container (child container 120) via the transfer filling flow path (132). In addition, by opening the injection flow path (131) and pressing the actuator (child actuator 130) while the injection port (parent stem connection part 136) is blocked with the transfer filling flow path blocking plug (135), the contents (content liquid F) in the container (child container 120) can be injected from the stem (child stem 122) through the injection flow path (131) and out of the actuator (child actuator 130). [Prior art documents] [Patent documents]
[0006] [Patent Document 1] International Publication No. 2023 / 127035 Summary of the Invention [Problem to be solved by the invention]
[0007] However, there is still room for improvement in the containers known from Patent Document 1 and the like.
[0008] In other words, when switching between injecting the contents into the secondary container and spraying the contents from the secondary container, the container of the refill aerosol system known from Patent Document 1 requires the removal and installation of the injection flow path blocker and the transfer filling flow path blocker, which could increase the number of work steps. Furthermore, since the injection flow path blocking plug and the transfer filling flow path blocking plug are designed to be detachable from the actuator, there was a risk that the injection flow path blocking plug and the transfer filling flow path blocking plug would be lost when removed from the actuator during injection or injection of the contents. In addition, since the propellant in the child container, which is filled outside the inner bag inside the child container, does not have a flow path for spraying outside the child container, the specifications of the propellant in the child container cannot be changed, and it is necessary to prepare child containers filled with propellant of different specifications depending on the application, which could complicate management. Furthermore, since the contents are filled into the inner bag of the child container while the propellant for the child container is already filled outside the inner bag inside the child container, the internal pressure inside the child container quickly rises before the contents have been sufficiently injected, which could result in a decrease in the speed at which the contents are filled from the parent container into the child container, or in the child container not being fully filled with the contents.
[0009] The present invention aims to solve these problems and to provide a container and content injection system that has a simple configuration, can inject contents quickly and sufficiently at a pressure suitable for spraying the contents, can easily change the specifications of the propellant for each content, and can easily inject and spray the contents without the need to replace parts. [Means for solving the problem]
[0010] The container of the present invention is a container having a valve unit to which multiple stems can be attached, a storage section to which the valve unit is attached at the mouth, and an actuator attached to the multiple stems, wherein the multiple stems include an injection stem for injecting contents into the storage section and an injection stem for spraying the contents outside the storage section, and the actuator has an injection body having an injection flow path communicating with the injection stem, and an injection stem fitting portion that fits into the injection stem and an injection body having a communicating flow path extending from the injection stem fitting portion, wherein the injection flow path passes through the injection body, and the main body portion is provided with an injection flow path extending from the communicating flow path and an injection port that communicates with the injection flow path and sprays the contents outside the injection body, and the injection body and the injection body are configured to be able to move independently, thereby solving the above-mentioned problem. [Effects of the Invention]
[0011] The container of the invention of claim 1 includes an injection stem for injecting the contents into the storage section and an injection stem for spraying the contents outside the storage section, and the actuator has an injection body provided with an injection flow path that communicates with the injection stem, and an injection body provided with an injection stem fitting portion that fits into the injection stem and an injection flow path extending from the injection stem fitting portion, the injection flow path passing through the injection body, and the injection body is provided with an injection flow path extending from the communicating flow path and an injection port that communicates with the injection flow path and sprays the contents outside the injection body, and the injection body and the injection body are configured to be able to move independently, so that, for example, the stem of an aerosol container into which the contents to be injected into the storage section have been injected can be connected so that it communicates with the injection flow path of the injection body, and the aerosol container can be pressed over the injection body to operate the stem of the aerosol container and the injection stem, thereby easily injecting the contents from the aerosol container into the storage section. In addition, by pressing the aerosol container against the injector to activate the injection stem over the injector, and by pressing the actuator to activate the injection stem fitted into the injector, the gas in the storage section can be discharged from the injection stem and the contents of the aerosol container can be quickly injected into the storage section from the injection stem. This makes it difficult for the internal pressure in the container to increase even if the contents are continuously injected into the container from the injection stem, so the contents can be injected into the container more quickly and sufficiently. Furthermore, if the contents of the aerosol container use liquefied gas as a propellant, even if the liquefied gas injected into the container from the injection stem along with the contents vaporizes and attempts to increase the internal pressure within the container, the vaporized liquefied gas within the container can be discharged from the injection stem operated together with the injection stem, allowing the contents and liquefied gas to be injected into the container quickly. Furthermore, since the gas inside the container can be easily discharged by simply pressing the ejection stem, the specifications of the propellant inside the container can be easily changed. Furthermore, since the injection body and the injection body are configured to be able to move independently, by pressing only the injection body that is fitted into the injection stem fitting portion of the injection stem, the contents in the storage section can be injected from the injection port without removing the injection body from the injection stem.Whether the contents are being injected or sprayed, there are no parts that need to be removed from the injection stem or the injection stem, and no parts will be lost.
[0012] According to the configuration described in claim 2, the injection body is provided with a sliding wall portion that slidably surrounds the injection body, so that the injection stem will not malfunction if a finger or the like accidentally touches the injection body. According to the configuration described in claim 3, a top surface portion is provided at the upper end of the sliding wall portion, which has a passage hole whose inner diameter is smaller than the outer diameter of the injection body and larger than the inner diameter of the injection port.Therefore, even if the injection body attached to the injection stem is pulled by the aerosol container fitted into the injection port and attempts to move in a direction away from the injection stem, the injection body interferes with the top surface portion, preventing it from coming off the injection stem.
[0013] According to the configuration of claim 4, a pressing surface that can press the actuator is provided on the upper part of the injection body, and when the injection body is attached to the injection stem, the pressing surface is located higher than the upper surface of the injection body attached to the injection stem.Therefore, when a user presses the pressing surface of the actuator to inject the contents in the storage section, the user is prevented from touching the injection body with their fingers, etc., and the contents can be reliably injected from the injection port without operating the injection stem. According to the configuration described in claim 5, the ejector is provided with a sliding wall portion that slidably surrounds the injection body, and the upper end of the sliding wall portion extends to the same height as the pressing surface.Therefore, when a user presses the pressing surface of the actuator to eject the contents in the storage section, even if the finger pressing the pressing surface comes into contact with the injection body, the finger can be caught on the upper end of the sliding wall portion, preventing contact with the injection body.
[0014] According to the configuration of claim 6, contents containing liquefied gas are injected into the storage section, so that, for example, if the contents injected from the injection body into the storage section contain the liquid phase of the liquefied gas used as a propellant, the contents and the propellant can be injected into the storage section simultaneously with a single operation. According to the configuration of claim 7, the injection body is formed integrally with the injection stem, so that, for example, by removing the injection body, fingers will not accidentally come into contact with the injection body or injection stem, and the contents in the storage section can be more reliably prevented from being accidentally sprayed from the injection side of the contents.
[0015] According to the configuration described in claim 8, the injection body and the ejection body are configured so that when the contents are ejected from the storage section, only the ejection body can be pressed, so that the contents do not flow back toward the injection body and fly out, but can be reliably ejected by passing through the ejection body side. According to the configuration of claim 9, the content injection system comprises a container and an injection unit having a delivery stem connectable to the injection body, the injection body having an injection port communicating with the injection flow path, the injection unit having an annular top surface, an attachment portion for attaching the delivery stem, and an annular recess formed between the annular top surface and the attachment portion, and the upper part of the injection body has a pressure-receiving portion that is positioned opposite the attachment portion when the delivery stem is engaged with the injection port.Therefore, for example, by connecting an injection device capable of pressure-feeding the content to be injected into the container to the injection unit, the delivery stem can be connected to the injection port, and the injection unit can be pressed over the injection body to operate the delivery stem and injection stem, thereby easily injecting the content in the injection device into the storage portion of the container. In addition, by pressing the injection unit against the injection body to operate the injection stem over the injection body and pressing the actuator to operate the injection stem fitted into the injection body, the gas in the storage section can be discharged from the injection stem and the contents in the injection device can be quickly injected into the storage section from the injection stem. This makes it difficult for the internal pressure within the container to increase even if the contents continue to be injected into the container from the injection stem, so the contents can be injected into the container more quickly and thoroughly. Furthermore, if the contents in the injection device use liquefied gas as a propellant, even if the liquefied gas injected into the storage section from the injection stem along with the contents vaporizes and attempts to increase the internal pressure inside the storage section, the vaporized liquefied gas inside the storage section can be discharged from the injection stem operated together with the injection stem, so the contents and liquefied gas can be injected into the storage section quickly. Furthermore, since the gas inside the container can be discharged simply by pressing the ejection stem, the specifications of the propellant inside the container can be easily changed. Furthermore, since the injection body and the injection body are configured to be able to move independently, by pressing only the injection body that is fitted into the injection stem fitting portion of the injection stem, the contents in the storage section can be injected from the injection port without removing the injection body from the injection stem.Whether the contents are being injected or sprayed, there are no parts that need to be removed from the injection stem or the injection stem, and no parts will be lost.
[0016] According to the configuration described in claim 10, a guide protrusion is provided on the upper part of the injection body that is guided into the annular recess when the delivery stem is fitted into the injection port.Therefore, when the contents are injected into the storage section using the injection unit, the guide protrusion guided into the annular recess allows the injection body and the injection unit to be positioned, and the contents can be injected reliably. According to the configuration of claim 11, the injection unit is an aerosol valve, which has a skirt portion formed in a ring shape that covers the mouth of the container, a pedestal portion formed inside the skirt portion and for attaching the delivery stem, and an annular recess formed between the skirt portion and the pedestal portion, and the upper part of the skirt portion is an annular top surface and the pedestal portion is an attachment portion, so that a general aerosol container can also be used as the injection unit.

DETAILED DESCRIPTION OF THE INVENTION
[0018] A contents injection system P according to one embodiment of the present invention will be described below with reference to the drawings.
[0019] As shown in Figures 1 to 4, a content injection system P according to one embodiment of the present invention is composed of a dispensing container 100 that sprays content M and an injection container 200 that injects content M into the dispensing container 100.
[0020] The dispensing container 100 has a valve unit 110 having an injection stem 113a and an ejection stem 113b, a storage section 120 in which the valve unit 110 is attached to the mouth, and an actuator 130 attached to the injection stem 113a and the ejection stem 113b.
[0021] The valve unit 110 has a housing 111, an injection section 112a and an injection section 112b that communicate with an injection stem 113a and an injection stem 113b, respectively, that are mounted within the housing 111, an injection side stem gasket 114a and an injection side stem gasket 114b that open and close the flow paths between the injection stem 113a and the injection stem 113b and the injection section 112a and the injection section 112b, and a spring S that biases the injection stem 113a and the injection stem 113b so as to close the flow paths between the injection stem 113a and the injection stem 113b and the injection section 112a and the injection section 112b. A dip tube 116 extending downward is connected to the injection section 112b, and an O-ring R is mounted between the outer surface of the housing 111 and the inner surface of the accommodating section 120. It should be noted that the injection stem 113a is longer than the ejection stem 113b.
[0022] The actuator 130 has an injector 131 that fits onto the injector stem 113a, and an ejector 140 that fits onto the ejector stem 113b. The injection body 131 has an injection stem fitting portion 132 that fits into the injection stem 113a, an injection port 134 that can be connected to the delivery stem 217 of the injection container 200 described below, and an injection flow path 133 that connects the injection stem fitting portion 132 and the injection port 134.
[0023] The injection body 140 has an injection stem fitting portion 141 that fits into the injection stem 113b, and a connecting flow path 142 that connects the injection stem fitting portion 141 to the injection flow path 143. The injection flow path 143 is connected to an injection port 144 that sprays the contents M outside the injection body 140. The upper part of the injection body 140 has a guide protrusion 147 that protrudes upward, a pressing surface 146 provided on the upper surface of the guide protrusion 147, a sliding wall portion 145 that forms a sliding hole 149 that penetrates the injection body 140 in the vertical direction, an enlarged diameter portion 148 formed in the shape of a hole above the sliding hole 149 and having a diameter larger than the sliding hole 149, and a pressed portion 152 formed between the sliding wall portion 145 and the enlarged diameter portion 148. The sliding hole 149 is formed to a size that allows the injection body 131 to slide therethrough, and the enlarged diameter portion 148 is formed to a size that allows the pedestal portion 214 (described later) to be inserted therethrough. Above the injection port 144, there is provided a tip abutment portion 151 that can abut against an annular top surface 213, which will be described later.
[0024] The injection container 200 functions as an injection unit of the content injection system P, and is composed of an aerosol valve 210 and an aerosol can 221 with the aerosol valve 210 attached to the opening thereof. The aerosol valve 210 has a mounting cup 211 that fits over an aerosol canister 221, a housing 216 attached to the mounting cup 211, a delivery portion 219 that communicates with a delivery stem 217 attached within the housing 216, a delivery stem gasket 218 that opens and closes the flow path between the delivery stem 217 and the delivery portion 219, and a spring S that biases the delivery stem 217 to close the flow path between the delivery stem 217 and the delivery portion 219, and a dip tube 220 extending downward is connected to the delivery portion 219.
[0025] Mounting cup 211 has a skirt portion 212 that covers the mouth of aerosol can 221, a pedestal portion 214 that holds housing 216, and an annular recess 215 between skirt portion 212 and pedestal portion 214, and skirt portion 212 covers the mouth of aerosol can 221 so as to sandwich cut gasket C between the upper part of the mouth and annular top surface 213. The aerosol can 221 is filled with contents M consisting of a liquid content F and a liquid phase of liquefied gas LG, and the gas phase portion inside the aerosol can 221 is filled with a gas phase G of liquefied gas, which generates a spray pressure for the contents M.
[0026] Next, the process of injecting the contents M into the storage section 120 by the contents injection system P according to one embodiment of the present invention will be described with reference to FIGS. For example, when the liquid content F of the content M and the liquid phase LG of the liquefied gas are separated, it is preferable to shake the aerosol can 221 sufficiently before pouring the content M into the container 120. First, as shown in Figure 4, the dispensing container 100 is positioned above the injection container 200 in an inverted state with the actuator 130 facing downward, and the dispensing container 100 is moved downward to a position where the delivery stem 217 is inserted into the injection port 134. At this time, since the expanded diameter portion 148 is formed to a size that allows the pedestal portion 214 to be inserted therethrough, by moving the dispensing container 100 downward while aligning the pedestal portion 214 with the expanded diameter portion 148, misalignment between the dispensing container 100 and the injection container 200 can be suppressed. Furthermore, by having the guide projection 147 enter the annular recess 215, it is possible to further prevent misalignment between the dispensing container 100 and the pouring container 200.
[0027] When the dispensing container 100 is further moved downward, the delivery stem 217 is connected to the injection port 134, and the injection stem 113a and the delivery stem 217 press against each other via the injection body 131. The sliding hole 149 is formed to a size that allows the injection body 131 to slide, and the enlarged diameter portion 148 is formed to a size that allows the pedestal portion 214 to be inserted, so that when the sub-portioning container 100 is continued to be moved downward, the injection body 131 moves only enough to press against the delivery stem 217, but the injection body 140 moves relative to the injection body 131 and moves further downward than the injection body 131, and the guide protrusion 147 penetrates even deeper into the annular recess 215. In other words, injection stem 113a and delivery stem 217 are pressed first without injection stem 113b being pressed, so that injection side stem gasket 114a and delivery stem gasket 218 bend, and the storage section 120 and the aerosol can 221 are connected via injection stem 113a, delivery stem 217, and injection body 131. As a result, the content M in the aerosol can 221 is injected into the container 120 by the pressure of the gas phase G of the liquefied gas. The storage section 120 is filled with the contents M injected into the storage section 120 and the gas phase G of the liquefied gas that is formed when the liquid phase LG of the liquefied gas of the contents M is vaporized, and the pressure inside the storage section 120 gradually approaches the pressure inside the aerosol can 221, and the injection rate of the contents M into the storage section 120 decreases.
[0028] Here, if the dispensing container 100 is moved further downward, at least one or all of the pressing surface 146, the pressed portion 152 which is the deepest part of the enlarged diameter portion 148, and the tip abutment portion 151 will come into contact with the bottom of the annular recess 215, the upper surface of the pedestal portion 214, and the annular top surface 213 of the skirt portion 212, respectively, thereby pressing the injection stem 113b fitted into the injection stem fitting portion 141. When the injection stem 113b is pressed, the injection side stem gasket 114b bends, and the gas phase G of the liquefied gas in the container 120 is injected from the injection stem 113b through the communication flow path 142 and the injection flow path 143 and out through the injection port 144 to the outside.
[0029] This reduces the pressure inside the container 120, increasing the pressure difference between the inside of the aerosol can 221 and the inside of the container 120, allowing the contents M to be injected from the inside of the aerosol can 221 into the container 120 more quickly and sufficiently. Furthermore, since the dispensing container 100 is in an inverted position and the dip tube 116 is connected to the spray portion 112b, the contents M are not sprayed from the spray nozzle 144 until the tip of the dip tube 116 is immersed in the contents M, and only the gas phase G of the liquefied gas is sprayed from the dip tube 116 through the spray nozzle 144 and out of the dispensing container 100.
[0030] When the pressure on the dispensing container 100 is released, the spring S causes the injection stem 113a, the spray stem 113b, and the delivery stem 217 to return to positions where the flow path is blocked by the injection side stem gasket 114a, the spray side stem gasket 114b, and the delivery stem gasket 218, respectively, stopping the injection of the contents M from inside the aerosol can 221 into the storage section 120 and the spray of the gas phase G of the liquefied gas from the storage section 120, and completing the injection of the contents M from inside the aerosol can 221 into the storage section 120.
[0031] As shown in Figure 6, when the dispensing container 100, in which the contents M have been poured into the storage section 120, is placed in an upright position, and then the pressing surface 146 is pressed with a finger or the like to push down the actuator 130, the spray stem 113b is pressed, and the contents M in the storage section 120 are ejected from the spray nozzle 144 by the pressure of the gas phase G of the liquefied gas from the dip tube 116 through the spray section 112b, the spray stem 113b, the connecting flow path 142, and the spray flow path 143. Furthermore, since the sliding hole 149 is formed to a size that allows the injection body 131 to slide, even if the pressure surface 146 is pressed to push down the injection body 140, the injection body 131 will slide against the sliding hole 149 and will not press against the injection stem 113a.
[0032] As described above, the contents M in the aerosol canister 221 can be easily and quickly and sufficiently injected into the container 120 simply by holding the dispensing container 100 upside down and pressing it against the injection container 200. Furthermore, since the contents M can be injected and sprayed without removing the parts of the actuator 130, there is no risk of losing parts that make up the actuator 130 when injecting or spraying the contents M.
[0033] Furthermore, when the injection stem 113a is fitted into the injection stem fitting portion 132, the injection body 131 is surrounded by the sliding wall portion 145 and does not protrude above the sliding hole 149, so fingers or the like cannot unintentionally touch the injection body 131, and the injection stem 113a will not malfunction, causing the contents M in the storage portion 120 or the gas phase G of the liquefied gas to be erroneously sprayed from the injection stem 113a. Furthermore, for example, as shown in Figure 7, if a top surface portion 153 is provided above the sliding hole 149, having a passage hole 154 that is smaller than the inner diameter of the sliding hole 149 and larger than the outer diameter of the delivery stem 217, and sufficient clearance is provided between the upper end of the injection body 131 engaged with the injection stem 113a and the lower end of the top surface portion 153, then after the injection of the contents M into the storage portion 120 is completed, when the subdivision container 100 is removed from the injection container 200, the top surface portion 153 will hinder the upward movement of the injection body 131, so that the delivery stem 217 can be reliably removed from the injection port 134.
[0034] Furthermore, the contents M are assumed to be liquid content F and liquid phase LG of liquefied gas, and are injected from the aerosol can 221 into the storage section 120 by the pressure of the gas phase G of the liquefied gas, or are sprayed from the nozzle 144 of the portioned container 100; however, the contents M in the aerosol can 221 can be liquid content F and compressed gas, and after only the liquid content F is injected from the aerosol can 221 into the storage section 120 by the pressure of the compressed gas, compressed gas or the like can be separately injected into the storage section 120 from the injection stem 113a via the injection body 131, and the liquid content F injected into the storage section 120 can be sprayed by the pressure of the compressed gas. Furthermore, the injection unit is not limited to a combination of aerosol valve 210 and aerosol can 221, but may also be a combination in which aerosol valve 210 is provided at the tip and connected to a device such as a pump that can pressurize contents M, content liquid F, liquid phase LG of liquefied gas, compressed gas, etc., and instead of aerosol valve 210, an injection attachment having attachment parts such as annular top surface 213, annular recess 215, and pedestal part 214 and having the same function as aerosol valve 210 can also be used.
[0035] Furthermore, the form in which the contents M are sprayed by the actuator 130 is not particularly limited, and for example, they do not have to be sprayed in the form of a mist, but may be sprayed in the form of a jet or foam. In addition, the shape of the nozzle 144 can be changed to suit the injection mode, and the nozzle part may be configured as a replaceable nozzle part separate from the injection body 140.
[0036] Furthermore, a configuration has been explained in which a dip tube 116 is connected to the spray portion 112b of the dispensing container 100 and a dip tube 220 is connected to the delivery portion 219 of the injection container 200, and by turning the dispensing container 100 in an inverted position and pressing it against the injection container 200 in an upright position, the contents M in the aerosol can 221 are injected into the storage portion 120. However, by removing the dip tubes from the spray portion 112b of the dispensing container 100 and the delivery portion 219 of the injection container 200 and connecting the dip tube to the injection portion 112a, the dispensing container 100 can be turned upright, and the inverted injection container 200 can be positioned above the dispensing container 100 and pressed, whereby the contents M in the aerosol can 221 can be injected into the storage portion 120 while the gas phase G of the liquefied gas in the storage portion 120 can be sprayed from the spray port 144, and the contents M can be injected into the storage portion 120 quickly and sufficiently. In addition, in the case where a dip tube is connected to the injection portion 112a and the dip tube is removed from the injection portion 112b, the contents M can be sprayed from the injection port 144 by turning the dispensing container 100 upside down and pressing the pressing surface 146.
[0037] Furthermore, if the injection section 112a, the spray section 112b, and the delivery section 219 are all configured without dip tubes, when injecting the contents M, the dispensing container 100 is placed in an upright position, and the contents M is injected from the inverted injection container 200, so that the contents M can be injected while spraying the gas phase G of liquefied gas from the spray nozzle 144, and when spraying the contents M, the dispensing container 100 is placed in an inverted position and the pressing surface 146 is pressed, so that the contents M can be sprayed from the spray nozzle 144. Furthermore, if dip tubes are connected to all of the injection section 112a, the injection section 112b, and the delivery section 219, when injecting the contents M, the dispensing container 100 is turned upside down and the contents M is injected from the injection container 200 which is turned upright, thereby allowing the contents M to be injected while spraying the gas phase G of liquefied gas from the injection port 144, and when spraying the contents M, the dispensing container 100 is turned upright and the pressing surface 146 is pressed, allowing the contents M to be sprayed from the injection port 144.
[0038] Furthermore, the injection body 131 does not have to be fitted to the injection stem 113a, and the injection body 131 and the delivery stem 217 may be fitted together, or the injection stem 113a and the delivery stem 217 may be directly abutted against each other. In particular, by providing grooves or protrusions at the tips of the injection stem 113a and the delivery stem 217 that can interlock with each other when they are placed facing each other, it is possible to inject the contents M only with a specific combination of the dispensing container 100 and the injection container 200, thereby preventing the wrong contents from being injected into the dispensing container 100.
[0039] Furthermore, if the injection body is configured to function as a female valve, the injection stem can be removed from the valve unit along with the injection body, so that the fingers pressing the injection body when injecting the contents will not accidentally come into contact with the injection body or injection stem, making it possible to more reliably prevent the contents in the storage section from being accidentally injected from the injection side of the contents. Furthermore, if the injection body that functions as a female valve is integrally formed with the delivery stem of the aerosol canister, the injection stem can be reliably removed from the valve unit together with the injection body when the contents are sprayed, and the injection body will not be lost. The outer diameter of the injection body integrally formed with the delivery stem does not necessarily have to be larger than the outer diameter of the delivery stem or the injection stem; for example, it may be the same as the outer diameter of the delivery stem or the injection stem, or it may be smaller than the outer diameter of the delivery stem or the injection stem.
[0040] Here, we will explain the contents of an experiment that examines the effect on the amount of content injected from the injection container to the injection container due to differences in the specifications of the injection container and the injection container in one embodiment of the content injection system of the present invention. The specifications of the portioning container and injection container were as shown in Table 1, and included Examples 1 to 7, in which the combinations of the injection side stem hole, injection side stem hole, delivery stem hole, VT hole, and filling ratio of the content liquid and liquefied gas of the portioning container were changed, as well as a comparative example in which the injection side stem was not activated. The injection side stem hole, the injection side stem hole, and the delivery stem hole are holes in the flow path that are blocked by the injection side stem gasket, the injection side stem gasket, and the delivery stem gasket, respectively, and the VT is a hole (vapor tap) separate from the delivery section 219 provided in the housing 216, as shown in Figure 8, and is a hole that communicates with the gas phase portion inside the injection container in the upright position.
[0041] The specific specifications of each component are as follows: Stem hole (small): 0.40mm x 0.8mm (square hole) x 2 holes Stem hole diameter (large): 1.2 mm x 3 holes VT hole diameter (small): 0.3mm VT hole diameter (large): 0.5mm Injection hole diameter: 2.0mm Injection part hole diameter: 1.0mm Delivery part hole diameter: 2.2mm Contents: Ethanol Liquefied gas: LPG (0.29 MPa)
[0042] [Table 1]
[0043] As shown in Figure 5, the test method involved pressing an inverted container close to an upright injection container, and injecting the contents from the injection container into the injection container to its full capacity. After five seconds of continuous injection, the weight of the injection container was checked and the amount of contents injected was measured. When it was confirmed that the contents had been sprayed from the nozzle while the contents were being poured from the injection container into the subdivision container, it was determined that the subdivision container had been filled to capacity. The experimental results are shown in Table 2.
[0044] [Table 2]
[0045] As shown in Table 2, although there were differences in the injection time between Examples 1 and 7, all of them were able to inject the full amount of contents, whereas in the comparative example, even when the injection time was extended, only 4 g or less of contents could be injected. This is because in the comparative example, the gas phase of the liquefied gas injected into the small container remains inside the small container, causing the pressure inside the small container to rise and become the same as the pressure inside the injection container, making it impossible to inject the contents due to the pressure difference. In addition, in the comparative example, it appears that the weight of the contents injected into the sub-portion container decreases as the injection time increases, but this is because the weight of the contents remaining in the injection body changes when the sub-portion container is removed from the injection container, and is within the range of error.
[0046] Although one embodiment of the present invention has been described in detail above, the present invention is not limited to the above embodiment, and various design modifications can be made without departing from the present invention as set forth in the claims.
[0047] In the above-described embodiment, the injection stem is formed to be longer than the injection stem, but the configuration of the injection stem and the injection stem is not limited to this. For example, the injection stem and the injection stem may be the same length, or the injection stem may be longer than the injection stem. Furthermore, in the above-described embodiment, the injection body is described as having a sliding wall portion that forms a sliding hole, and the injection body slides within the sliding hole, but the configuration of the injection body is not limited to this. For example, the sliding wall portion may surround the injection body, and a slit may be provided in part of the sliding wall portion that passes through in the vertical direction, and a protrusion that protrudes radially outward may be provided on the outer peripheral surface of the injection body so that it can pass through the slit, thereby allowing the injection body to slide in the vertical direction without rotating, and the sliding wall portion or sliding hole may not be required.
[0048] Furthermore, in the above-described embodiment, the injection body is provided with a guide protrusion, and the guide portion is configured to be able to enter the annular recess of the mounting cup, but the configuration of the injection body is not limited to this, and for example, the guide protrusion may not be present. Furthermore, in the above-described embodiment, the injection body is provided with a tip abutment portion, which is configured to be able to abut against the annular top surface of the mounting cup, but the configuration of the injection body is not limited to this, and for example, the injection body may not have a tip abutment portion, and the tip abutment portion may be provided around the entire circumference of the injection body.
[0049] Furthermore, in the above-described embodiment, it has been explained that when the contents are injected, the injection stem and delivery stem are pressed first, connecting the aerosol canister and the storage section via the injection body, and then the injection stem is pressed, connecting the nozzle and the storage section. However, the configuration of the present invention is not limited to this, and for example, the aerosol canister may be configured to connect the storage section and the storage section and the nozzle simultaneously, or the storage section may be configured to connect the nozzle before the aerosol canister connects the storage section.
