Description

Technical Field

[0005] , ,

[0001] This application relates to a container for containing liquid or semi - liquid products, and particularly to an improvement in the configuration of a product dispenser in the container.

Background Art

[0002] In industries such as daily necessities, pharmaceuticals, and food, containers for containing liquid or semi - liquid products usually have product dispensers such as pressing pumps and nozzles for dispensing the liquid or semi - liquid products inside the container. In the process of product dispensing, as the product in the container decreases, a negative pressure is generated inside the container, which not only causes the container to contract due to this negative pressure but also makes it difficult to dispense the product. To solve the problem of container contraction, the product dispenser is provided with a balance pore or a balance passage, which can replenish the air outside the container into the container while dispensing the product outside the container, thereby preventing the container from contracting.

[0003] However, there are also some problems with such an air replenishment method. One of these problems is that the air replenished into the container is the air in the surrounding environment, and there are microorganisms such as bacteria and viruses in the environmental air. When these microorganisms enter the container, they come into contact with the liquid or semi - liquid product inside the container and multiply in large numbers, which has an adverse effect on the properties of the product. To suppress the growth of microorganisms, additives such as preservatives and antibacterial agents are formulated in the product. However, these additives can irritate the human skin and mucous membranes, causing discomfort to the body, and even damage to body organs such as the skin. Moreover, when the product is a drug, food, etc., such additives should not be added at all.

[0004] Therefore, in order to overcome the above problems, it is necessary to further improve the configuration of the container with a product dispenser.

Summary of the Invention

Problems to be Solved by the Invention

[0005] This invention was made to solve the technical problems that exist in the prior art. The object of this invention is to provide a container with a product dispenser having an improved configuration that can compensate for the negative pressure generated inside the container after the product has been dispensed from the container, and can prevent microorganisms and contaminants in the air from coming into contact with the product and contaminating it. [Means for solving the problem]

[0006] The present invention discloses a product dispenser that is attached to a container for distributing a liquid or semi-liquid product from the container to the outside. The product dispenser comprises an air bag, the air bag having at least one opening, at least one opening communicating with the outside of the container to receive ambient air from outside the container, or communicating with the inside of the container to replenish the inside of the container with gas, thereby compensating for negative pressure occurring inside the container.

[0007] In the product dispenser with the above configuration, an air supply bag is provided, which can be pre-filled with a clean gas such as clean air or nitrogen gas. During the process of distributing the product in the container, the pre-filled gas can be replenished into the container, or the air supply bag can be placed inside the container and filled with gas to compensate for negative pressure during the product distribution process. This ensures that the gas in contact with the product is clean, or that the gas used for negative pressure equilibrium is isolated from the product. This prevents contamination of the product.

[0008] In one embodiment, the air supply bag is pre-filled with gas, and at least one opening of the air supply bag communicates with the inside of the container. When the product is dispensed from the container to the outside, gas is replenished from the air supply bag into the inside of the container. Since the pre-filled gas is clean, it does not contaminate the product.

[0009] More specifically, the product dispenser is a press-type product dispenser, comprising a press head, a screw sleeve, and a cylinder. A piston rod is connected to the lower part of the press head, and a piston is provided on the piston rod, with a seal fitting formed between the piston and the inner wall of the cylinder.

[0010] In this type of product dispenser, the air supply bag can be installed in a space formed by the engagement of the pressing head and the screw sleeve. When the pressing head is pressed to distribute the product to the outside, the air supply bag is also pressed, so that the gas pre-filled in the air supply bag can be replenished into the container.

[0011] Furthermore, an auxiliary air bag is formed in the side wall of the cylinder, communicating with at least one opening of the auxiliary air bag.

[0012] Preferably, the piston can function as an opening and closing component for the equilibrium pore. Specifically, the piston is configured to be located in the equilibrium pore and close it when the product dispenser is not pressed, and to move downward away from the equilibrium pore and open it when the product dispenser is pressed to dispense the product.

[0013] Alternatively, a cylinder plug may be fitted to the cylinder, and the cylinder plug may have an equilibrium vent that communicates with at least one opening of the supplemental air bag. The equilibrium vent may be fitted with a one-way intake valve, which is configured to allow the gas in the supplemental air bag to flow into the container but to prevent the gas from flowing back from the container to the supplemental air bag.

[0014] In another specific configuration, the air supply bag is installed outside the container, the container has a container opening which communicates with at least one opening in the air supply bag, and the container opening is provided with a one-way valve which is configured to allow the gas in the air supply bag to flow into the container but to prevent the flow of gas from the container to the air supply bag.

[0015] In yet another specific configuration, the supplemental air bag is installed inside the container and communicates with the outside of the container through equilibrium pores formed in the product dispenser. When the product is distributed from the container to the outside, creating negative pressure in the container, outside air can flow into the supplemental air bag through the equilibrium pores.

[0016] More specifically, the product dispenser is a press-type product dispenser, comprising a press head, a screw sleeve, and a cylinder. A piston rod is connected below the press head, a piston is provided on the piston rod, a seal fitting is formed between the piston and the inner wall of the cylinder, and equilibrium holes are provided on the side wall of the cylinder or on the screw sleeve.

[0017] Alternatively, the product dispenser comprises a drip nozzle and a dispenser body, the dispenser body being installed inside the drip nozzle, the air supply bag being connected to the dispenser body, and at least one opening of the air supply bag communicating with the inner cavity of the dispenser body.

[0018] In a drip nozzle type product dispenser, a first through-hole is formed in the side wall of the drip nozzle, and a second through-hole is formed in the side wall of the dispenser body. The second through-hole is aligned with the first through-hole and extends into the lumen of the dispenser body.

[0019] Preferably, the product dispenser further comprises an intake valve, which is configured to allow outside air to flow into the supplemental air bag and to prevent the outflow of gas from within the supplemental air bag.

[0020] In one embodiment, the intake valve is installed in the lumen of the distributor body, and the intake valve comprises a mounting portion and an elastic valve plate, the mounting portion being attached to the lumen of the distributor body, and the elastic valve plate being installed between the supplemental air bag and the lumen of the distributor body.

[0021] Alternatively, in another embodiment, the air supplement bag includes an attachment member for attaching the air supplement bag to the dispenser body, and the intake valve is formed on the attachment member. The intake valve includes a valve plate, and the valve plate is connected to the attachment member via at least one elastic bar. When the attachment member is attached to the dispenser body, the valve plate of the intake valve can be biased towards the inlet from the air supplement bag into the inner cavity of the dispenser body. There may be one elastic bar or a plurality of elastic bars, for example, three.

[0022] Also, the product dispenser is a hand-held dispenser, and the air supplement bag of the product dispenser is connected below the product dispenser and is located inside the container.

[0023] Regarding the air supplement bag, its bag body may be stretchable in the radial direction, may be stretchable in the axial direction, or may be stretchable in both the radial and axial directions.

[Modes for carrying out the invention]

[0026] Specific embodiments of the present invention will be described in detail below with reference to the drawings. It should be understood that the drawings show only preferred embodiments of the present invention and do not limit the scope of the invention. Those skilled in the art can make various obvious modifications, changes, and equivalent substitutions to the present invention based on the embodiments shown in the drawings, and can freely combine the technical features of the different embodiments described below, as long as they do not contradict each other, and any such combination falls within the scope of protection of the present invention.

[0027] <First Example> Figures 1 and 2 show a container 10 having a product dispenser 100 in a first embodiment of the present application. Figure 1 shows the product dispenser 100 in a standby state where it is not pressed, while Figure 2 shows the product dispenser 100 in a state after use.

[0028] The product dispenser 100 comprises a pressing head 110 and a screw sleeve 120, the pressing head 110 being movable vertically along the axial direction of the product dispenser 100 relative to the screw sleeve 120, and the pressing head 110 being fixedly attached to the container 10 by means of a screw, for example. A piston rod 140 is connected below the pressing head 110, and the piston rod 140 is movable along the axial direction in conjunction with the pressing head 110. The product dispenser 100 further comprises a cylinder 150 fixedly connected to the screw sleeve 120. Preferably, a cylinder plug 151 is also attached to the cylinder 150.

[0029] A piston 141 is provided on the piston rod 140, and the piston 141 is positioned inside the cylinder 150. A seal fitting is formed between the piston 141 and the inner wall of the cylinder 150, so that the product inside the cylinder 150 can be distributed as the piston 141 moves inside the cylinder 150.

[0030] In the first embodiment, the product dispenser 100 further includes an air bag 130 located in the space formed by the fitting of the pressing head 110 and the screw sleeve 120. The air bag 130 is pre-filled with a gas, such as clean air or an inert gas such as nitrogen. The air bag 130 has two openings, namely a first opening 131 and a second opening 132, the first opening 131 which seals around the piston rod 140, and the second opening 132 which is connected to the screw sleeve 120 and communicates with the internal space of the container 10.

[0031] A balance hole 152 is formed in the side wall of the cylinder 150, extending through the side wall of the cylinder 150. The auxiliary air bag 130 communicates with the balance hole 152 through the gap between the piston rod 140, the cylinder plug 151, and the cylinder 150, and is also in communication with the inside of the container 10.

[0032] Preferably, the piston 141 can function as an opening and closing mechanism for the equilibrium vent 152. In the upper standby state shown in Figure 1, the piston 141 is in the position of the equilibrium vent 152, closing it. When the pressing head 110 is pushed down to move the piston 141 to the position shown in Figure 2, the piston 141 moves away from the position of the equilibrium vent 152, opening it. At this time, the gas in the supplementary air bag 130 enters the container 10 through the gap between the piston rod 140 and the cylinder 150 and cylinder plug 151, compensating for the negative pressure created by product distribution.

[0033] Preferably, the volume of gas pre-filled in the gas bag 130 is essentially the same as the volume of the product in the container 10. In this way, after all the product in the container 10 has been distributed, all the gas in the gas bag 130 also enters the container 10, and the gas bag 130 enters the contracted state shown in Figure 2.

[0034] More preferably, in the standby state shown in Figure 1, the upper ring of the piston 141 is fitted to the lower end of the cylinder plug 151, and further performs a sealing function.

[0035] Preferably, the pressing head 110 is further provided with a shut-off valve 112 (also called a one-way drain valve), which is configured to allow the product to be dispensed from the container 10 through the nozzle port 111 via the product dispenser 100, but to prevent outside air from flowing back into the product dispenser 100 and into the container 10.

[0036] In the product dispenser 100 described above, the air supply bag 130 can be manufactured by various methods, for example, by processes such as injection molding, blow molding, injection blow molding, and gas assist, or by using film or bags. The material of the air supply bag 130 may also be various materials known in the art. Preferably, in order to enhance the sealing effect of the air supply bag 130, the air supply bag 130 can be formed using a multilayer structure and / or composite material.

[0037] Next, the operating principle of the configuration of the first embodiment will be explained with reference to Figures 1 and 2.

[0038] In the standby state shown in Figure 1, the supplemental air bag 130 is filled with pre-filled air, and the equilibrium vent 152 is closed by the piston 141.

[0039] In the state shown in Figure 2, the pressing head 110 is pushed down so that the piston rod 140 and the piston 141 attached thereto move downward, and the product in the cylinder 150 is discharged by pressure. At the same time, the piston 141 moves away from the equilibrium hole 152 and opens the equilibrium hole 152, allowing the gas in the supplemental air bag 130 to enter the container 10 and compensate for the negative pressure generated inside the container 10.

[0040] <Second Example> Figures 3 and 4 show a second embodiment of the present application, in which a product dispenser 200 is attached to the container 10. Unless otherwise stated or inconsistent, the specific configurations described for the first embodiment above can also be applied to the second embodiment. The differences in configuration between the second embodiment and the first embodiment will be described in detail below.

[0041] As shown in Figure 3, a product dispenser 200 is attached to the container 10. The product dispenser 200 comprises a pressing head 210 to which a piston rod 240 is connected, and a screw sleeve 220. An air supply bag 230 is provided in the space formed by the pressing head 210 and the screw sleeve 220 so as to surround the piston rod 240.

[0042] The supplemental air bag 230 has an opening 231 at one end (the lower end shown in the figure), and this opening 231 is connected to the cylinder plug 251 of the product dispenser 200. The cylinder plug 251 is also provided with a balancing hole 252, which communicates with the internal space of the container 10, for example, through the gap between the screw sleeve 220 and the cylinder plug 251.

[0043] Preferably, the cylinder plug 251 is further provided with a one-way intake valve 253, which allows the gas in the supplemental air bag 230 to flow into the container 10, but prevents the product or other contents in the container 10 from flowing into the supplemental air bag 230.

[0044] In one specific configuration, the one-way intake valve 253 is an elastic sheet located below the opening 231. When the pressing head 210 is pressed, the supplemental air bag 230 is pressurized, and the pressure of the gas pre-filled in the supplemental air bag 230 deforms the one-way intake valve 253, opening the equilibrium vent 252 and allowing the gas in the supplemental air bag 230 to flow into the container 10. When the pressing force on the pressing head 210 is removed, the one-way intake valve 253 adheres to the equilibrium vent 252, closing the equilibrium vent 252.

[0045] Similar to the first embodiment, the volume of gas pre-filled in the supplemental gas bag 230 is preferably the same as the volume of the product in the container 10.

[0046] <Third Example> Figures 5 and 6 show a third embodiment of the present invention, in which a product dispenser 300 is attached to the container 10. Unless otherwise stated or inconsistent, the specific configurations described for the first and second embodiments above can also be applied to the third embodiment. The following describes in detail the configurations in the third embodiment that differ from those of the first and second embodiments.

[0047] As shown in Figures 5 and 6, the container 10 of the third embodiment is fitted with a product dispenser 300, specifically the product dispenser 300 is fitted with the first container opening 11 of the container 10, for example, the first container opening 11 is formed at the top of the container 10.

[0048] The product distributor 300 is equipped with an air supply bag 330, which is pre-filled with a gas such as clean air or an inert gas such as nitrogen gas. The container 10 is provided with a second container opening 12, and the air supply bag 330 is connected to the second container opening 12, which is formed at the bottom of the container 10, for example, as shown in the figure. A one-way valve 331 is provided at the connection point between the air supply bag 330 and the second container opening 12, and the one-way valve 331 is configured to allow the gas in the air supply bag 330 to flow into the container 10, but to prevent the product in the container 10 from flowing into the air supply bag 330.

[0049] Preferably, the system further includes an air bag case 13, which is installed around the supplemental air bag 330 and connected to the container 10, and which serves to protect the supplemental air bag 330.

[0050] When the product in container 10 is distributed via the product distributor 300, the pressure inside container 10 decreases, creating negative pressure. This negative pressure opens the one-way valve 331, and the gas in the air supply bag 330 is replenished into container 10.

[0051] In the illustrated configuration, the supplemental air bag 330 is connected to the bottom of the container 10, but the supplemental air bag 330 may also be connected to other locations on the container 10. For example, if the cross-section of the container 10 is square or rectangular, the second container opening 12 may be opened on the side of the container 10, and the supplemental air bag 330 and the air bag case 13 for the supplemental air bag 330 may be connected to the side of the container 10.

[0052] In addition to the press-type product dispenser shown in the figure, other types of product dispensers may also be used.

[0053] <Fourth Example> Figures 7 and 8 show a fourth embodiment of the present application, in which a product dispenser 400 is attached to the container 10. Unless otherwise stated or inconsistent, the specific configurations described for the first to third embodiments can also be applied to the fourth embodiment. The following describes in detail the configurations of the fourth embodiment that differ from those of the first to third embodiments.

[0054] In the fourth embodiment, a product dispenser 400 is attached to the container 10. The product dispenser 400 comprises a pressing head 410 and a screw sleeve 420. The screw sleeve 420 is fixedly connected to a cylinder 450, and the cylinder 450 is provided with a cylinder plug 451.

[0055] The product dispenser 400 further comprises an air bag 430, the open end of which is fixedly attached below the screw sleeve 420. For example, in the exemplary configuration shown in the figure, one end of the open end of the air bag 430 is interposed between the screw sleeve 420 and the opening of the container 10, and the other end is fixedly connected to the outer surface of the cylinder 450 or fixed to the lower part of the screw sleeve 420.

[0056] The screw sleeve 420 has an equilibrium pore 421 formed in it, which leads to the inside of the supplemental air bag 430. In this way, when the product inside the container 10 is distributed and negative pressure is generated inside the container 10, outside air enters the supplemental air bag 430 through the equilibrium pore 421, and the negative pressure inside the container 10 can be compensated for.

[0057] As outside air enters the air supply bag 430, the air supply bag 430 isolates the air from the product inside the container 10, preventing contamination of the product by outside air, and also compensating for the negative pressure that occurs inside the container 10 as the product is distributed.

[0058] Preferably, as shown in Figures 7 and 8, the cylinder plug 451 can function as an opening and closing mechanism for opening and closing the equilibrium vent 421. Specifically, the cylinder plug 451 has an outer flange, which is provided to cover the equilibrium vent 421, and an equilibrium airway 452 is formed in the outer flange of the cylinder plug 451. For example, a groove is formed at the bottom of the outer flange to allow the cylinder plug 451 to communicate with the outside. The cylinder plug 451 is rotatably mounted relative to the cylinder 450 and the screw sleeve 420 so that the equilibrium airway 452 can be aligned or offset from the equilibrium vent 421.

[0059] When the cylinder plug 451 is rotated to a position where the equilibrium airway 452 is aligned with the equilibrium vent 421, the product can be dispensed. As the product is dispensed from the container 10, outside air flows into the supplemental air bag 430 to compensate for the resulting negative pressure. If it is not necessary to dispense the product to the outside, the cylinder plug 451 can be rotated to a position where the equilibrium airway 452 and the equilibrium vent 421 are misaligned, in which case outside air does not enter the supplemental air bag 430.

[0060] <Fifth Example> Figures 9 and 10 show a fifth embodiment of the present application, in which a product dispenser 500 is attached to the container 10. Unless otherwise stated or inconsistent, the specific configurations described for the first to fourth embodiments are also applicable to the fifth embodiment. The following describes in detail the configurations of the fifth embodiment that differ from those of the first to fourth embodiments.

[0061] In the fifth embodiment, a product dispenser 500 is attached to the container 10. The product dispenser 500 comprises a pressing head 510, a screw sleeve 520, a piston rod 540, and a cylinder 550. A piston 541 is provided on the piston rod 540. The product dispenser 500 further comprises an air supply bag 530, which is located inside the container 10, and the open end of the air supply bag 530 is sealed and fitted to the outer circumference of the cylinder 550.

[0062] Equilibrium pores 542 are formed in the side wall of the cylinder 550, and these equilibrium pores 542 communicate with the inside of the supplemental air bag 530. The piston 541 can function as an opening and closing mechanism for opening and closing the piston 541.

[0063] In the standby state shown in Figure 9, the piston 541 is in the upper position, aligned with the equilibrium vent 542, and closes the equilibrium vent 542. When the pressing head 510 is pressed down, as shown in Figure 10, the piston 541 moves downward and opens the equilibrium vent 542, thereby pressurizing the product inside the container 10 to the outside, and at the same time, outside air enters the supplemental air bag 530 through the equilibrium vent 542, compensating for the negative pressure generated as the product is pressurized.

[0064] In one exemplary configuration, the lower end of the air supply bag 530 can be sealed and fitted to the suction pipe 560.

[0065] The air supply bag 530 isolates the outside air it contains from the product inside the container 10, preventing contamination of the product inside the container 10 by the outside air.

[0066] <Sixth Example> Figures 11 and 12 show a sixth embodiment of the present application, in which a product dispenser 600 is attached to the container 10. Unless otherwise stated or inconsistent, the specific configurations described for the first to fifth embodiments are also applicable to the sixth embodiment. The following describes in detail the configurations of the sixth embodiment that differ from those of the first to fifth embodiments.

[0067] A product dispenser 600 is attached to the container 10, and the product dispenser 600 comprises a pressing head 610, a screw sleeve 620, a piston rod 640, and a cylinder 650. A piston 641 is provided on the piston rod 640. A cylinder plug 651 is provided on the cylinder 650.

[0068] The product distributor 600 further comprises an air bag 630, the upper open end of which is connected downwards, the connection configuration of which can be seen in the fourth embodiment.

[0069] In the sixth embodiment, a balance airway 621 is provided below the screw sleeve 620, and the balance airway 621 communicates with the outside through a gap formed between the cylinder 650 and the cylinder plug 651, a gap formed between the cylinder plug 651 and the piston rod 640, and a gap between the pressing head 610 and the screw sleeve 620. While distributing the product in the container 10, outside air can flow into the supplemental air bag 630 through the balance airway 621.

[0070] Preferably, the piston 641 engages with the lower end of the cylinder plug 651 and can perform the function of opening and closing the passage to the equilibrium airway 621 from the outside. Specifically, in the state shown in Figure 11, the piston 641 is in sealing contact with the lower end of the cylinder plug 651, blocking communication between the gap between the cylinder plug 651 and the cylinder 650 and the gap between the cylinder plug 651 and the piston rod 640. However, in the state shown in Figure 12, the piston 641 and the cylinder plug 651 are separated, opening the passage.

[0071] <Seventh Example> Figures 13 to 20 show a seventh embodiment of the present invention, in which a product dispenser 700 is attached to the container 10. Unless otherwise stated or inconsistent, the specific configurations described for the first to sixth embodiments can also be applied to the seventh embodiment. The following describes in detail the configurations of the seventh embodiment that differ from those of the first to sixth embodiments.

[0072] In the sixth embodiment, the product dispenser 700 attached to the container 10 is specifically of the drip nozzle type, the container 10 has a variable volume, and the product inside the container can be pushed out by compressing the container 10.

[0073] The product dispenser 700 is equipped with a drip nozzle 710. As shown in Figure 15, a first through-hole 711 is formed in the side wall of the drip nozzle 710, extending through the side wall of the drip nozzle 710. A drain port 712 is formed at the top of the drip nozzle 710.

[0074] A distributor body 720 is provided inside the drip nozzle 710, and Figures 16 and 17 show the specific configuration of the distributor body 720. As shown in Figure 16, a one-way drain valve 721 is formed at the top of the distributor body 720, and when the one-way drain valve 721 is fitted with the drain port 712, the product in the container 10 is distributed through the drain port 712, and outside air is prevented from flowing into the container from the drain port 712.

[0075] A second through-hole 722 is formed in the side wall of the distributor body 720, extending into the lumen of the distributor body 720. The second through-hole 722 is aligned with the first through-hole 711, thereby forming a balanced pore so that the inside of the supplemental air bag 730 communicates with the outside of the product distributor 700. The supplemental air bag 730 is connected to the bottom of the distributor body 720, and the internal space of the supplemental air bag 730 communicates with the lumen of the distributor body 720. Furthermore, an intake valve 740 is provided in the lumen of the distributor body 720, and the intake valve 740 is configured to allow outside air to flow into the supplemental air bag 730 through the first through-hole 711 and the second through-hole 722, while preventing reverse air flow. Figure 18 shows a perspective view of the intake valve 740, which includes an upper mounting portion 741 for attaching the intake valve 740 to the lumen of the distributor body 720. An elastic valve plate 742 is formed at the lower end of the intake valve 740, which is located between the lumen of the distributor body 720 and the supplemental air bag 730, and specifically fits into an inlet leading from the supplemental air bag 730 to the lumen of the distributor body 720, thereby enabling unidirectional airflow from the outside into the inside of the supplemental air bag 730.

[0076] The connection of the air supply bag 730 to the distributor body 720 can be achieved by various known methods, such as convex-ring-concave fitting or screwing.

[0077] As shown in Figure 17, a groove is further formed on the side wall of the distributor body 720. This groove functions as a drainage passage 723 between the distributor body 720 and the drip nozzle 710.

[0078] Preferably, as shown in the figure, the product dispenser 700 further comprises a seal cover 20, the seal cover 20 having a projection that closes the drain port 712 of the drip nozzle 710.

[0079] As shown in Figure 19, when the body of the container 10 is compressed, the pressure acting on the product inside the container 10 increases, causing the product to flow into the drain passage 723 and the one-way drain valve 721 to open, and the product to flow out of the drain port 712 as shown by arrow A in Figure 19. When the pressing force on the container 10 is removed, the container 10 attempts to return to its original shape, and negative pressure is formed inside the container 10. This negative pressure closes the one-way drain valve 721 and opens the intake valve 740, allowing air to flow into the supplemental air bag 730 through the first through-hole 711 and the second through-hole 722, thus compensating for the negative pressure inside the container 10 as shown by arrow B in Figure 20.

[0080] <Eighth Example> Figures 21 to 23 show an eighth embodiment of the present invention, in which a product dispenser 800 is attached to the container 10.

The mounting member 831 is provided with an intake valve 840, which includes a valve plate 841, and the elastic valve plate 841 is connected to the top of the mounting member 831 via an elastic bar 842.

[0083] When the air supply bag 830 is attached to the distributor body 820, as shown in Figure 21, the elastic bar 842 bends elastically, and the valve plate 841 comes into contact with the opening in the lumen of the distributor body 820 that leads to the inside of the air supply bag 830.

[0084] Figure 23 shows another embodiment of the intake valve 840, in which the valve plate 841 is connected to the inner wall of the mounting member 831 of the supplemental air bag 830 via a plurality of elastic bars 842 (three in the figure).

[0085] <Ninth Example> Figures 24 to 26 show the ninth embodiment of the present invention, in which a product dispenser 900 is attached to the container 10. Unless otherwise stated or inconsistent, the specific configurations described for the first to eighth embodiments can also be applied to the ninth embodiment. The following describes in detail the configurations in the ninth embodiment that differ from those of the first to eighth embodiments.

[0086] As shown in Figure 24, the product dispenser 900 is equipped with an air supply bag 930, which has a bellows-shaped bag body and can expand and contract in the axial direction. Figure 25 shows a perspective view of the bellows-shaped air supply bag 930.

[0087] In addition, as shown in Figure 26, the bag body of the air supply bag 930 may be expandable and contractible in the radial direction.
