Abstract
Description
Technical Field
[0001] The embodiments relate to a pressure regulating device and a sealed container system including the same. Background Technology
[0002] Food spoils over time due to its inherent properties, so containers used for long-term food preservation need to be airtight to prevent the food from coming into contact with outside air and / or moisture.
[0003] This type of food is usually stored in airtight containers, such as cans.
[0004] Because these cans are made of metal, it is difficult for customers to directly check the condition of the food inside. As a result, customers cannot directly check the freshness and other conditions of the food before purchasing.
[0005] In addition, simply sealing the food completely off from the outside may not be suitable depending on the type of food being contained.
[0006] For example, when the food contained in the container is fermented, the food produces gas over time. This gas cannot escape to the outside of the sealed container, which may eventually cause the container to burst and cause problems, or the food contained may spoil easily. Summary of the Invention
[0007] Technical issues
[0008] As mentioned above, the existing sealing methods, especially for the storage and / or distribution of fermented foods, have limitations, leading to an increasing demand for a food packaging method that can maintain the freshness of the fermented foods contained within.
[0009] One objective of this invention is to address the problems and / or limitations described above, particularly by providing a pressure regulating device and a sealed container system comprising the same, capable of maintaining the airtight properties of fermented foods while keeping the contents fresh by venting gas.
[0010] Technical solution
[0011] To achieve the aforementioned objective, one embodiment provides a container system comprising: a container having an interior receiving portion having a first surface and a second surface facing each other, the first surface facing the receiving portion and selectively sealed to receive at least one gas-generating container in the receiving portion, and having at least one opening; and a pressure regulating device coupled to at least the second surface of the container to cover the opening, configured to discharge at least a portion of the gas in the receiving portion to the outside when a first gas pressure inside the container is higher than a second gas pressure outside the container, and to cut off the flow of gas from the outside of the container to the receiving portion when the first gas pressure is lower than the second gas pressure; wherein the pressure regulating device includes: a first membrane structure configured to allow gas permeability within the receiving portion to be greater than liquid permeability within the receiving portion; and a second membrane structure configured to allow unidirectional venting of gas from the receiving portion to the outside; wherein the first membrane structure is located on the second surface of the container to cover the opening, and the second membrane structure is configured to cover the first membrane structure.
[0012] The pressure regulating device may also include an adhesive film, which may be configured to have one side attached to a second side of the holding unit and the other side attached to the first film structure and the second film structure.
[0013] The adhesive film can be configured to also be located between the first film structure and the second film structure.
[0014] The pressure regulating device may be configured such that gas discharged from the containment through the opening is directed toward the second thin film structure after passing through the first thin film structure.
[0015] The pressure regulating device may also include an adhesive film, which may be configured such that one side is bonded to the second side of the container and the first film structure, and the other side is bonded to the second film structure.
[0016] The pressure regulating device may also include an adhesive film, which may be configured such that one side is attached to a second side of the container and the other side is attached to the first film structure.
[0017] A portion of the second thin-film structure may be configured to be attached to a second side of the holding unit at least outside the first thin-film structure.
[0018] The pressure regulating device may also include an adhesive film, and a portion of the second film structure may be configured to be attached to the second side of the holding unit at least outside the first film structure, through the adhesive film, wherein the adhesive film may be configured to be attached to the second side of the holding device on one side and to the first film structure on the other side.
[0019] According to another embodiment of the present invention, a pressure regulating device can be provided, which can be combined with a container having a receiving portion for accommodating at least a gas-generating substance and an opening formed in the receiving portion. The pressure regulating device includes: a first thin film structure configured such that the permeability of gas in the receiving portion is greater than the permeability of liquid in the receiving portion; and a second thin film structure configured to enable unidirectional venting of gas in the receiving portion toward the outside; wherein the first thin film structure is formed with an area capable of covering the opening of the receiving device, and the second thin film structure is configured to cover the first thin film structure.
[0020] The pressure regulating device may further include: an adhesive film; and a fourth film structure facing the first film structure; wherein the adhesive film may be configured such that one side can be bonded to the fourth film structure and the other side can be bonded to the first film structure and the second film structure.
[0021] The adhesive film can be configured to also be located between the first film structure and the second film structure.
[0022] The pressure regulating device may be configured such that gas discharged from the containment through the opening can pass through the first thin film structure toward the second thin film structure.
[0023] The pressure regulating device may further include: an adhesive film; and a fourth film structure facing the first film structure; wherein the adhesive film may be configured such that one side is bonded to the fourth film structure and the first film structure, and the other side is bonded to the second film structure.
[0024] The pressure regulating device may further include: an adhesive film; and a fourth film structure facing the first film structure; wherein the adhesive film may be configured such that one side is bonded to the fourth film structure and the other side is bonded to the first film structure.
[0025] The pressure regulating device may further include a fourth thin film structure facing the first thin film structure; wherein a portion of the second thin film structure may be configured to be joined to the fourth thin film structure on the outside of the first thin film structure.

[0027] [Invention Effects]
[0028] According to the embodiments of the present invention described above, while maintaining the airtightness of the container, the internal gas can be smoothly discharged to prevent food spoilage.
[0029] Because it allows the food inside the container to remain fresh for as long as possible, food can be contained in the container without a food sterilization process, thus enabling higher quality food distribution.
[0030] One embodiment of the sealed container can be cooked directly in a microwave oven, thus offering a wider range of food options that can be contained and circulated, making cooking simpler and more useful for food storage.
[0031] Moreover, the pressure regulating device can be easily manufactured and can be placed on the outside of the container instead of inside, thus eliminating problems such as the reduced functionality of the pressure regulating device due to food contamination.
[0032] By using a plastic material that allows external light to pass through the container, consumers can directly visually inspect the condition of the food inside. At the same time, this can further improve the airtightness of the container and prevent the food from spoiling.
[0033] By manufacturing the pressure regulating device into a single unit, process yield and productivity can be significantly improved. Attached Figure Description

[0056] This invention can be modified in various ways and has multiple embodiments. Specific embodiments will be exemplarily shown in the accompanying drawings and described in detail in the summary of the invention. (Refer to the following and accompanying drawings.) Figure 1 As will become clear from the detailed description of the embodiments, the effects and features of the present invention, as well as the methods for achieving them, will be apparent. However, the present invention is not limited to the embodiments disclosed below and can be embodied in various forms.
[0057] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. When describing the invention with reference to the accompanying drawings, the same or corresponding constituent elements will be assigned the same reference numerals, and repeated descriptions thereof will be omitted.
[0058] In the following embodiments, the singular expression includes the plural expression unless the context explicitly indicates otherwise.
[0059] In the following embodiments, terms such as "including" or "having" mean the presence of the features or constituent elements described in the specification, without pre-excluding the possibility of adding more than one other feature or constituent element.
[0060] In the following embodiments, when referring to a membrane, region, constituent element, or other part above or on other parts, it includes not only the case where it is immediately above other parts, but also the case where other membranes, regions, constituent elements, etc. exist in between.
[0061] Where a particular embodiment may be manifested differently, a specific sequence of operations may also be performed differently than the order in which they are described. For example, two operations described consecutively may be performed substantially simultaneously, or they may be performed in the reverse order of their description.
[0062] In the accompanying drawings, the dimensions of the constituent elements may be exaggerated or reduced for ease of description. For example, the sizes and thicknesses of the various components shown in the figures are arbitrarily depicted for the sake of descriptive convenience, and therefore the following embodiments are not necessarily limited to what is shown.
[0063] Figure 1 A brief illustration of a sealed container system is shown.
[0064] like Figure 1 As shown, an embodiment of the sealed container system may include a container 1 and a pressure regulating device 2.
[0065] The container 1 may have an internal containment 123, which may be selectively sealed to contain at least the gas-generating contents in the containment 123.
[0066] According to one embodiment, the holding device 1 can be configured as follows: Figure 1 The bent-overlap joint container shown may include a container 12, a lid 11, and a bent-overlap joint 13.
[0067] The container 12 may be formed of a plastic material and has an internal receiving portion 123 configured to contain a gas-generating substance within the receiving portion 123. A container body 121 is configured to surround the receiving portion 123. According to one embodiment, the substance may be a fermented food.
[0068] The plastic material forming container 12 can be any plastic material that can be molded into a container shape. The plastic material forming container 12 can be a microwave-safe plastic material, such as polypropylene, high-density polyethylene, crystalline polyethylene terephthalate, or heat-resistant polystyrene. The container 12 can be formed of a transparent plastic material so that the contents can be displayed, allowing consumers to directly visually confirm the state of the food contained inside the container. Alternatively, a plastic material that is not damaged during distribution and, as described later, easily bonded to the metal lid 11 can be used. According to one embodiment, transparent polypropylene can be used as the plastic material forming container 12.
[0069] The lid 11 can be made of a thin sheet metal. The metal material forming the lid 11 can be aluminum, specifically high-purity aluminum. This high-purity aluminum is suitable for use in microwave ovens. According to one embodiment, the lid 11 can be smoothly formed without wrinkles or sharp edges on the surface. Therefore, charge concentration on the surface of the lid 11 due to microwaves can be prevented. The lid 11 can also provide rigidity to prevent damage during storage and / or distribution.
[0070] The bent and overlapping joint 13 is located between the container 12 and the lid 11, and is configured to seal the lid 11 within the container 12.
[0071] The bent-overlap joint 13 may be configured to have an arc-shaped surface. The bent-overlap joint 13 may be located at the inlet edge of the container 12 and the edge of the lid 11, and is formed by the combination of the container 12 and the lid 11.
[0072] More specifically, the bent overlapping joint 13 is as follows: Figure 15 As shown, it can be configured along the inlet edge of container 12 and may include: a first end 131, which is abutted against the side wall of the first body 121 of container 12; a second end 132, which faces the first end 131; and a connecting portion 133, which is located between the first end 131 and the second end 132 and has an arc-shaped surface.
[0073] The bent and overlapping joint 13 of this structure can maintain the container's seal more stably because the first end 131 is in a state of being close to the side wall of the first body 121 of the container 12. In addition, by keeping the third flange 113 inserted between the bent first flange 122 and the first body 121, the airtightness of the container's interior can be further improved.
[0074] When the container 12 is formed of a plastic material with low ductility, by making the length of the first flange 122 of the container inlet sufficiently long, thereby achieving the following: Figure 8 After being fully bent downwards as shown, the end can be bent upwards again, and a portion of the third flange 113 and / or the first flange 122, which are made of highly ductile metal, is pushed between the first flange 122 and the first body 121 to fit tightly, thereby forming the shape of the aforementioned bent overlapping joint 13.
[0075] According to one embodiment, the first length t1 between the upper surface of the second body 111 of the cover 11 and the second end portion 132, which serves as the upper end of the bent-overlap joint 13, can be longer than the second length t2 from the first end portion 131 to the second end portion 132 of the bent-overlap joint 13. This is because during the pressing process using rollers, the second flange 112 is pushed upwards to a certain extent, thus allowing the bent-overlap joint 13 to achieve a more compact size when viewed from the outside. Since the bent-overlap joint 13 is not formed too thick, the sealed appearance of the container can also be further improved.
[0076] like Figure 1As shown, one embodiment of the container system may include a pressure regulating device 2, which is used to regulate the gas pressure inside the container 1. It may be configured to discharge at least a portion of the gas in the containment section 123 to the outside when the first gas pressure P1 inside the container 1 is higher than the second gas pressure P2 outside the container 1. Therefore, when fermented food is contained in the containment section 123 of the container 1 for storage and / or distribution, if the gas pressure inside the containment section 123 rises excessively due to gas generated by the fermented food, the gas is automatically discharged to the outside by means of the pressure regulating device 2, thereby preventing the container 1 from exploding due to gas generated by the fermented food. On the other hand, when the first gas pressure P1 is lower than the second gas pressure P2, the pressure regulating device 2 cuts off the gas flow from the outside of the container 1 to the containment section 123, thereby preventing the food contained in the containment section 123 from spoiling due to external impurities flowing into the containment section 123.
[0077] Figure 2 yes Figure 1 Top view of the cover 11 Figure 3 yes Figure 2 A cross-sectional view of AA. (Refer to...) Figure 2 and Figure 3 This describes a pressure regulating device 2 according to one embodiment.
[0078] In one embodiment, the pressure regulating device 2 can be integrated with the lid 11 of the container 1. The lid 11 in one embodiment may include a first surface 11-1 and a second surface 11-2 facing each other. The first surface 11-1 may be the surface facing the aforementioned receiving portion, and the second surface 11-2 may be the surface facing outwards from the receiving portion. In one embodiment, the pressure regulating device 2 can be integrated with the second surface 11-2.
[0079] At least one opening 14 may be formed on the cover 11, through which the first surface 11-1 and the second surface 11-2 can communicate with each other. This opening 14 can be selectively sealed by covering it with the pressure regulating device 2.
[0080] One embodiment of the pressure regulating device 2 may include a first thin film structure 21 and a second thin film structure 22.
[0081] The first thin film structure 21 may be equipped with a greater permeability to gases than to liquids.
[0082] According to one embodiment, the first thin film structure 21 can be formed of a porous polymer material. The porous polymer material can have a pore size of 0.2 μm to 1.5 μm. When the pore size is less than 0.2 μm, gas inside the containment is difficult to escape smoothly, which may even lead to an explosion of the container. When the pore size is greater than 1.5 μm, there is a risk of bacteria invading through the porous polymer material. The porous polymer material can be a membrane with multiple pores regularly and / or irregularly dispersed, and this membrane can be a single-layer structure and / or a multi-layer structure of a single material and / or multiple materials.
[0083] According to one embodiment, the diaphragm of the first thin film structure 21 may be hydrophobic and / or oil-resistant. According to one embodiment, the diaphragm may include an acrylic copolymer material, a polyethersulfone material, and / or a nylon nonwoven fabric skeleton.
[0084] According to this embodiment of the first film structure 21, fermentation gases inside the container can pass through the pores of the diaphragm, but liquids cannot. Therefore, liquid from the food contained in the receiving portion 123 of the container 1 can be prevented from flowing out of the container 1. Furthermore, liquids can be prevented from entering the container from the outside through the first film structure 21. Therefore, impurities and / or bacteria can be prevented from entering the receiving portion 123 from the outside of the container 1.
[0085] The second film structure 22 can be configured to allow one-way exhaust of gas from the containment portion 123 to the outside. For this purpose, the second film structure 22 can have a one-way exhaust port 225 formed on at least one side. This second film structure 22 can be formed as a thin film, for example, a polyethylene terephthalate film, and can be formed to a thickness of 10 μm to 25 μm to provide flexibility. Therefore, when the gas pressure inside the containment portion 123 is higher than the external gas pressure, the second film structure 22 partially bulges outward due to the gas inside the containment portion 123, at which point the one-way exhaust port 225 can open and communicate with the opening 14. Thus, the gas inside the containment portion 123 can be exhausted to the outside through the one-way exhaust port 225. On the other hand, when the gas pressure inside the containment portion 123 is lower than the external gas pressure, the external pressure compresses the outside of the second film structure 22, pressurizing the second film structure 22 in the direction of closing the opening 14, thereby closing the one-way exhaust port 225.
[0086] This second thin-film structure 22 can be bonded at least partially to the second surface 11-2 using an adhesive third thin-film structure 23 as a medium. The second thin-film structure 22 is attached to an area, shape, and location that can completely cover the opening 14. In this case, at least a portion of the second thin-film structure 22, for example, the portion communicating with the opening 14, is not bonded to the third thin-film structure 23 and the second surface 11-2, thereby forming a second through-hole 22-1. A one-way exhaust port 225 communicating with the opening 14 can be formed on at least one side of the second through-hole 22-1. Figure 2 In this invention, the second thin film structure 22 is a structure that is elongated along one direction, but the invention is not necessarily limited to this and can also be formed in various shapes such as circles, ellipses and / or polygons.
[0087] The third film structure 23 can be an adhesive film, using pressure-curing, heat-curing, and / or UV-curing adhesive materials. This third film structure 23 is used to adhere one side to the second surface 11-2, and can be formed with a third through-hole 23-1 adjacent to the opening 14. The width D2 of the third through-hole 23-1 can be wider than the width D1 of the opening 14, and the opening 14 can be located within the area of the third through-hole 23-1. Figure 2 In the figure, the third through-hole 23-1 is formed in a straight line along the vertical direction of the figure, that is, it is formed to be open along the vertical direction of the figure. Therefore, the one-way exhaust port 225 of the second thin film structure 22 is formed on the upper and lower sides of the figure. However, the present invention is not limited to this. The shape of the third through-hole 23-1 can be formed to be open only to one side, so that the one-way exhaust port 225 can be formed only on one side.
[0088] According to one embodiment, the first thin film structure 21 can also be bonded to the second surface 11-2 by means of the third thin film structure 23.
[0089] That is, firstly, the third thin film structure 23, having a third through-hole 23-1, is joined to the second surface 11-2, and above it, the first thin film structure 21 is fixedly joined in a manner that overlaps with the opening 14. At this time, the width D3 of the first thin film structure 21 is formed to be wider than the width D2 of the third through-hole 23-1. Therefore, all the gas exiting from the opening 14 can pass through the first thin film structure 21.
[0090] The second thin film structure 22 is configured to cover the first thin film structure 21. At this time, by making the width D3 of the first thin film structure 21 smaller than the overall width of the third thin film structure 23, the second thin film structure 22 can be joined to the third thin film structure 23 outside the outline of the first thin film structure 21. Alternatively, the first thin film structure 21 and the second thin film structure 22 can be left unjoined. Therefore, gas passing through the first thin film structure 21 can be discharged to the outside through the one-way exhaust port 225 of the second thin film structure 22.
[0091] As described above, according to one embodiment, the first film structure 21 can be located upstream of the exhaust gas flow, compared to at least a portion of the second film structure 22, for example, compared to the one-way exhaust port 225. Therefore, by means of the first film structure 21, liquid from the fermented food contained in the containment portion 123 cannot pass through, only the fermentation gas can be discharged, and only this fermentation gas can be discharged to the outside through the one-way exhaust port 225 of the second film structure 22.
[0092] In addition, according to Figure 2 Although shown as one end of the first thin film structure 21 abutting against the one-way exhaust port 225, the invention is not necessarily limited thereto, and the outer boundary of the first thin film structure 21 may be located at least inside the one-way exhaust port 225.
[0093] Reference Figure 2 The second thin film structure 22 is wider in the left-right direction than the width D3 of the first thin film structure 21, so that the second thin film structure 22 can completely cover the first thin film structure 21. (Refer to...) Figure 2 The boundary line of the second thin film structure 22 along the vertical direction can abut against the boundary line of the first thin film structure 21 along the vertical direction. Therefore, in the manufacturing process, the process can be simplified by simultaneously cutting off the first thin film structure 21 and the second thin film structure 22.
[0094] However, the present invention is not necessarily limited to this. The boundary line of the second thin film structure 22 along the vertical direction can also be wider than the boundary line of the first thin film structure 21 along the vertical direction, so that in the vertical direction of the figures, the second thin film structure 22 can completely cover the first thin film structure 21. That is, the second thin film structure 22 can completely cover the first thin film structure 21 as a whole. Therefore, the gas passing through the first thin film structure 21 can be discharged through the one-way exhaust port 225 formed by the second thin film structure 22 instead of being directly discharged. Moreover, since the first thin film structure 21 is not exposed to the outside, it can be prevented from being contaminated, and the intrusion of foreign substances and / or bacteria can be cut off at the source. This sealing structure of the first thin film structure 21 can be applied to all embodiments of this specification.
[0095] Figure 4 Another embodiment of the pressure regulating device 2 is shown, with Figure 3 Compared to the illustrated embodiment, the third thin film structure 23 may include a third base film 230, a third-1 bonding film 231, and a third-2 bonding film 232. The remaining components are the same as... Figure 3 The embodiments shown are the same, so they will not be described again.
[0096] The third base film 230 can be a rigid, thin film. According to one embodiment, it can be, but is not limited to, a polyethylene terephthalate film. For example, a film with low wettability to liquids can be used.
[0097] The third-1 bonding film 231 is located between the third base film 230 and the second surface 11-2, so that the third base film 230 is bonded to the second surface 11-2. The third-2 bonding film 232 is located between the third base film 230 and a portion of the first film structure 21 and between the third base film 230 and a portion of the second film structure 22, so that the first film structure 21 and the second film structure 22 are fixed to the third base film 230.
[0098] The third base film 230, the third-1 bonding film 231, and the third-2 bonding film 232 can be formed to have the same third through-hole 23-1.
[0099] By utilizing the stacked structure of the third base film 230, the third-1 bonding film 231 and the third-2 bonding film 232 as described above, the operability of the third film structure 23 can be improved, and the manufacturing process of the pressure regulating device can be simplified.
[0100] Figure 5 A pressure regulating device 2 is shown as yet another embodiment.
[0101] The first thin film structure 21 may include a first base film 210 and a first bonding film 211; the second thin film structure 22 may include a second base film 220 and a second bonding film 221; and the third thin film structure 23 may include a third base film 230 and a third bonding film 231. The first base film 210 and the second base film 220 may be respectively composed of… Figure 3 The thin film formation of the first thin film structure 21 and the second thin film structure 22 is shown in the embodiment.
[0102] The third base film 230 can be bonded to the second surface 11-2 by means of the third bonding film 231, and the first base film 210 can be bonded to the third film structure 23 by means of the first bonding film 211. The second base film 220 can be bonded to the third film structure 23 by means of the second bonding film 221.
[0103] At this time, the first bonding film 211 has a first through-hole 21-1, the width of which can be greater than the width of the opening 14. According to one embodiment, the width of the first through-hole 21-1 can be greater than or equal to the width of the third through-hole 23-1.
[0104] The second bonding film 221 also has a second through-hole 22-1, the width of which can be greater than the width of the first film structure 21.
[0105] In this structure, the aforementioned one-way exhaust port is formed by the shape of the second through-hole 22-1, so that the shape of the second through-hole 22-1 can be formed with at least one side open, so as to connect with...

The plastic material forming the container 12 can be a microwave-safe material, such as polypropylene, high-density polyethylene, crystalline polyethylene terephthalate, or heat-resistant polystyrene. The container 12 can use a plastic material that is easily bent and overlapped with a metal material to form the lid 15. According to one embodiment, transparent polypropylene can be used as the plastic material forming the container 12.
[0173] This container 12, as Figure 21 As shown, a first flange 122 may be present along the edge of the entrance.
[0174] The bent-overlap joint cover 15 can be formed from a thin sheet metal material. The metal material forming the bent-overlap joint cover 15 can be aluminum, specifically high-purity aluminum. This high-purity aluminum is suitable for use in microwave ovens. The bent-overlap joint cover 15 provides rigidity that prevents damage during storage and / or distribution.

That is, the second flange 152 is bent downwards from the connecting flange 154, and the third flange 153 is bent upwards from the second flange 152 and faces the second flange 152. Moreover, the end of the first flange 122 can be bent upwards so that the first flange 122 and the bent end of the first flange 122 are located between the second flange 152 and the third flange 153. Therefore, the bent and overlapping joint 13 has a structure in which the third flange 153, the end of the first flange, the first flange 122 and the second flange 153 are sequentially attached to the outside of the body 121 of the container 12.

An opening 14 can be formed on one side so that the pressure regulating device 2 can be installed.
[0184] According to one embodiment, the sealed bag 16 may include various forms of stand-up pouches known in the art. Therefore, a bottom film 164 folded into a U-shape and / or V-shape may be attached to the lower part of the sealed bag 16. This bottom film 164 may include a film of the same material as the bag-shaped film 161.
[0185] Additionally, a zipper that can be opened and closed may be provided on the open upper part of the sealed bag 16.
