Description

Technical Field

[0001] This utility model relates to the field of kitchenware, and more particularly to a sealing device for food storage bags. Background Technology

[0002] As people's living standards improve, the usage rate of sous-vide cookers is also increasing. Sous-vide cookers use relatively low temperatures to heat food in a water bath for a long time, which can ensure the tenderness of food while avoiding the destruction of its nutrients, making them very popular. However, because sous-vide cookers require food to be placed in a plastic bag and sealed and vacuumed, most existing sealing devices can only seal the opening of the plastic bag and cannot vacuum at the same time. Their function is relatively limited. The plastic bag must be vacuumed first and then sealed, which is not only cumbersome and difficult to operate, but also results in poor vacuum sealing and a poor user experience. Utility Model Content

[0003] This application provides a sealing device for food preservation bags to solve the technical problems that sealing devices have relatively simple functions, and that vacuum sealing of food preservation bags is not only cumbersome and difficult to operate, but also has poor vacuum sealing effect and poor user experience.

[0004] To solve the above-mentioned technical problems, this utility model provides a sealing device for a food storage bag, including a first hinge and a second hinge that are movably clamped at the opening of the food storage bag. A locking structure is provided between the first hinge and the second hinge to press the first hinge and the second hinge together. A hinge sealing element is provided on the opposite surfaces of the first hinge and the second hinge. The hinge sealing element is provided with a needle slot for vacuuming the inside of the food storage bag; or, a bag opening sealing element is clamped between the first hinge and the second hinge. The bag opening sealing element is provided with a needle slot for vacuuming the inside of the food storage bag. By installing the first and second hinges at the opening of the food storage bag and using the locking structure to press and fit them together, the opening of the food storage bag can be sealed, facilitating water bath heating of the food inside. Simultaneously, by providing hinge sealing elements on the opposing surfaces of the first and second hinges, a better seal is achieved at the opening of the food storage bag, preventing air leakage or external liquids from entering the bag during cooking, thus ensuring the sealing stability and effectiveness of the sealing device. Furthermore, by providing inserts for vacuuming the inside of the food storage bag on the hinge sealing elements or the bag opening sealing elements, the sealing device can vacuum the bag through these inserts, effectively enhancing the functional versatility of the sealing device, thereby improving its practicality and applicability, and also significantly improving user convenience and experience.

[0005] In an optional embodiment, one end of the first hinge and the second hinge are adapted to be hinged together, and the hinge is provided with the locking structure. The locking structure includes a plurality of elastic buckles connected to the first hinge and the second hinge. The elastic buckles are used to generate a reaction force opposite to the rotation direction of the first hinge and the second hinge when the first hinge and the second hinge are rotated to separate them. By providing the locking structure that generates a reaction force opposite to the rotation direction of the first hinge and the second hinge at the hinged end, the first hinge and the second hinge can automatically clamp together when the user installs the sealing device, thereby sealing the opening of the food storage bag. This not only effectively reduces the disassembly and installation difficulty of the sealing device, but also effectively improves the user's convenience, thereby enhancing the user experience.

[0006] In an optional embodiment, the ends of the first hinge and the second hinge that are hinged to each other are respectively provided with a first gripping portion and a second gripping portion. The first gripping portion and the second gripping portion are adapted to extend outward at an angle away from each other. The first gripping portion and the second gripping portion are adapted to perform a gripping function. By providing the first gripping portion and the second gripping portion at the ends of the first hinge and the second hinge that are hinged to each other, it is convenient for the user to grip the first gripping portion and the second gripping portion to install and remove the sealing device. This not only effectively improves the user's ease of use, but also makes it easier for the user to install and remove the sealing device, thus effectively improving the user experience.

[0007] In an optional embodiment, the hinge seal is further provided with a temperature-measuring slit for inserting a food probe to measure the temperature of food inside the preservation bag. The temperature-measuring slit is adapted to be spaced apart from the needle insertion slit. By providing the temperature-measuring slit on the hinge seal, spaced apart from the needle insertion slit, not only can temperature measurement and vacuuming be prevented from interfering with each other, effectively improving temperature measurement accuracy and vacuuming efficiency, but users can also insert the food probe through the needle insertion slit and the temperature-measuring slit into different locations on the food to measure the temperature at different locations, avoiding differences in the food's cooking area and effectively improving the food cooking effect; or,

[0008] The bag opening seal is also provided with a temperature measuring slit for inserting a food probe to measure the temperature of the food inside the bag. The temperature measuring slit is adapted to be spaced apart from the needle insertion slit. By providing the temperature measuring slit on the bag opening seal that is spaced apart from the needle insertion slit, not only can temperature measurement and vacuuming be achieved without interference, effectively improving the accuracy of temperature measurement and the efficiency of vacuuming, but users can also insert the food probe into different positions of the food through the needle insertion slit and the temperature measuring slit to measure the temperature of different positions of the food, avoiding the situation of differences in the food cooking area and effectively improving the food cooking effect.

[0009] In an optional embodiment, one end of the first hinge and the second hinge are adapted to be hinged together, and the other end is adapted to be separably fastened by the locking structure. By hinged one end of the first hinge and the second hinge together and separably fastened by the locking structure, not only can the user easily install and disassemble the sealing device, effectively improving user convenience, but it can also ensure the sealing stability of the first hinge and the second hinge when clamping the bag opening, effectively improving the sealing effect.

[0010] In an optional embodiment, the locking structure includes a snap fastener on one of the first hinge and the second hinge, and a hook on the other hinge that matches the snap fastener. The snap fastener is adapted to be detachably engaged with the hook. By providing the snap fastener and the hook on the first hinge and the second hinge respectively, making the first hinge and the second hinge detachably engageable, the connection structure of the first hinge and the second hinge can be simplified, thereby reducing the production cost and user cost of the sealing device. Furthermore, the difficulty of disassembling and installing the sealing device can be reduced, effectively improving user convenience.

[0011] In an optional embodiment, the opposing surfaces of the first hinge and the second hinge are formed with clearance grooves that match the bag opening seal. The bag opening seal is adapted to be detachably clamped within the clearance grooves. The clearance grooves are adapted to position and / or limit the bag opening seal. Positioning and / or limiting the bag opening seal through the clearance grooves not only effectively reduces the installation difficulty of the bag opening seal and improves user convenience, but also prevents the bag opening seal from sliding freely during installation, thus affecting the sealing effect. This effectively ensures the sealing stability and sealing effect of the sealing device. At the same time, by placing the bag opening seal within the clearance grooves, the contact area between the bag opening seal and the first and second hinges is increased, thereby improving the sealing effect of the sealing device when clamped at the opening of the food storage bag.

[0012] In an optional embodiment, one of the bag opening seal and the clearance groove is provided with a limiting part, and the other is provided with a limiting groove corresponding to and matching the limiting part. When the bag opening seal is disposed in the clearance groove, the limiting part is adapted to engage with the limiting groove. The limiting part and the limiting groove are adapted to position and / or limit the installation of the bag opening seal. By using the limiting part and the limiting groove to position and / or limit the installation of the bag opening seal, the installation difficulty of the bag opening seal can be effectively reduced, improving the user's convenience. It can also prevent the bag opening seal from coming out of the clamps of the first hinge and the second hinge during installation, thereby causing the seal to fail. This effectively ensures the sealing stability and performance stability of the sealing device.

[0013] In an optional embodiment, the hinge seal includes a first hinge seal on the first hinge and a second hinge seal on the second hinge. When the first and second hinges are pressed together, the mating surfaces of the first and second hinge seals are adapted to form the pin gap. This arrangement not only simplifies the structure of the sealing device, thereby reducing production and user costs, but also ensures the sealing effect of the pin gap can be maintained by replacing the first and / or second hinge seals when the pin gap is damaged, effectively guaranteeing the sealing stability and performance stability of the sealing device.

[0014] In an optional embodiment, the opposing surfaces of the first hinge and the second hinge are provided with mounting grooves corresponding to the hinge seal, and the hinge seal is at least partially confined within the mounting grooves. The mounting grooves are adapted to position and / or limit the installation of the hinge seal. Positioning and / or limiting the installation of the hinge seal through the mounting grooves not only effectively reduces the installation difficulty of the hinge seal, thereby reducing production and user costs, but also prevents the hinge seal from sliding during installation, which could lead to poor sealing performance. This effectively ensures the sealing stability and sealing effect of the sealing device.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] This application achieves a sealed seal at the opening of a food storage bag by installing a first hinge and a second hinge at the bag opening and using a locking structure to press and engage the first and second hinges together. This allows users to heat the food inside the bag in a water bath. Simultaneously, by providing hinge sealing elements on the opposing surfaces of the first and second hinges, a better seal is achieved at the bag opening, preventing air leakage or external liquid from entering the bag during cooking, which could lead to poor cooking results. This effectively ensures the sealing stability and effectiveness of the sealing device. Furthermore, by providing a vacuum-sealing slit on the hinge sealing element or the bag opening sealing element, the sealing device can vacuum the bag through the slit. This not only effectively enhances the functional versatility of the sealing device, thereby improving its practicality and applicability, but also significantly improves user convenience and experience.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.

[0031] Example 1:

[0032] Appendix Figure 1 To be continued Figure 4 The diagram shown is a schematic diagram of a first embodiment of a sealing device for a food storage bag provided by this utility model. The sealing device includes a hinge assembly 10 that can be movably clamped at the opening of the food storage bag. The hinge assembly 10 includes a first hinge 11 and a second hinge 12. A locking structure 20 is provided between the first hinge 11 and the second hinge 12 to press the first hinge 11 and the second hinge 12 together. A hinge sealing element 13 made of elastic high-temperature resistant materials such as rubber and silicone is provided on the opposite surfaces of the first hinge 11 and the second hinge 12. The hinge sealing element 13 is provided with a needle slot 30 for vacuuming the inside of the food storage bag. By installing the first hinge 11 and the second hinge 12 at the opening of the food storage bag and using the locking structure 20 to press the first hinge 11 and the second hinge 12 together, the opening of the food storage bag can be sealed, allowing the user to heat the food inside the bag in a water bath. Simultaneously, by installing the hinge sealing element 13 on the opposite surfaces of the first hinge 11 and the second hinge 12, a better seal can be achieved at the opening of the food storage bag, preventing air leakage or external liquid from entering the bag during food cooking. The sealing device effectively ensures the sealing stability and sealing effect of the sealing device, preventing poor food cooking results inside the fresh bag. In addition, by providing the insertion pin slit 30 on the hinge seal 13 for vacuuming the inside of the fresh bag, the sealing device can not only seal the fresh bag, but also vacuum the fresh bag through the insertion pin slit 30. This not only effectively improves the functional versatility of the sealing device, thereby enhancing its practicality and applicability, but also effectively improves user convenience and user experience.

[0033] like Figures 1 to 4As shown, in an optional embodiment, one end of the first hinge 11 and the second hinge 12 is adapted to be hinged to each other. A locking structure 20 is provided at the hinge point. The locking structure 20 preferably includes a plurality of elastic latches 21 connected to the first hinge 11 and the second hinge 12. The elastic latches 21 are used to generate a reaction force opposite to the rotation direction of the first hinge 11 and the second hinge 12 when the first hinge 11 and the second hinge 12 are rotated to separate them. By providing the locking structure 20, which generates a reaction force opposite to the rotation direction of the first hinge 11 and the second hinge 12, at the hinged end of the first hinge 11 and the second hinge 12, the first hinge 11 and the second hinge 12 can automatically clamp together when the user installs the sealing device, thereby sealing the opening of the food storage bag. This not only effectively reduces the difficulty of disassembling and installing the sealing device but also effectively improves user convenience, thus enhancing the user experience.

[0034] like Figures 1 to 4 As shown, in an optional embodiment, the ends of the first hinge 11 and the second hinge 12 that are hinged to each other are respectively provided with a first gripping portion 111 and a second gripping portion 121. The first gripping portion 111 and the second gripping portion 121 are adapted to extend outward at an angle away from each other. The first gripping portion 111 and the second gripping portion 121 are adapted to perform a gripping function. By providing the first gripping portion 111 and the second gripping portion 121 at the ends of the first hinge 11 and the second hinge 12 that are hinged to each other, it is convenient for the user to grip the first gripping portion 111 and the second gripping portion 121 to install and remove the sealing device. This not only effectively improves the user's ease of use, but also makes it easier for the user to install and remove the sealing device, effectively improving the user experience.

[0035] like Figure 1 and Figure 4 As shown, in an optional embodiment, the hinge seal 13 is further provided with a temperature measuring slit 40 for inserting a food probe to measure the temperature of food inside the preservation bag. The temperature measuring slit 40 is adapted to be spaced apart from the needle insertion slit 30. By providing the temperature measuring slit 40 on the hinge seal 13, which is spaced apart from the needle insertion slit 30, not only can temperature measurement and vacuuming be achieved without interference, effectively improving the accuracy of temperature measurement and the efficiency of vacuuming, but users can also insert the food probe into different positions of the food through the needle insertion slit 30 and the temperature measuring slit 40 to measure the temperature of different positions of the food, avoiding differences in the food's cooking area and effectively improving the food cooking effect.

[0036] like Figure 1 and Figure 4As shown, in an optional embodiment, the hinge seal 13 includes a first hinge seal 131 disposed on the first hinge 11 and a second hinge seal 132 disposed on the second hinge 12. When the first hinge 11 and the second hinge 12 are pressed together, the mating surfaces of the first hinge seal 131 and the second hinge seal 132 are adapted to form the pin slot 30. This arrangement not only simplifies the structure of the sealing device, thereby reducing production and user costs, but also ensures the sealing effect of the pin slot 30 by replacing the first hinge seal 131 and / or the second hinge seal 132 when the pin slot 30 is damaged, effectively guaranteeing the sealing stability and performance stability of the sealing device.

[0037] like Figure 2 As shown, in an optional embodiment, the surfaces of the first hinge 11 and the second hinge 12 opposite to each other are provided with mounting grooves 14 corresponding to the hinge seal 13, and the hinge seal 13 is at least partially confined within the mounting grooves 14. The mounting grooves 14 are adapted to position the hinge seal 13 during installation. Positioning the hinge seal 13 using the mounting grooves 14 effectively reduces the installation difficulty of the hinge seal 13, thereby reducing production and user costs. Simultaneously, the mounting grooves 14 are also adapted to limit the installation of the hinge seal 13. Limiting the installation of the hinge seal 13 using the mounting grooves 14 prevents the hinge seal 13 from sliding during installation, thus avoiding poor sealing performance and effectively ensuring the sealing stability and sealing effect of the sealing device.

[0038] Example 2:

[0039] Appendix Figure 5 To be continued Figure 8The diagram shown is a schematic diagram of a second embodiment of a sealing device for a food storage bag provided by this utility model. The sealing device includes a hinge assembly 10 that can be movably clamped at the opening of the food storage bag. The hinge assembly 10 includes a first hinge 11A and a second hinge 12A. A locking structure 20A is provided between the first hinge 11A and the second hinge 12A to press the first hinge 11A and the second hinge 12A together. A hinge sealing element 13A made of elastic high-temperature resistant materials such as rubber and silicone is provided on the opposite surfaces of the first hinge 11A and the second hinge 12A. A bag opening sealing element 15A is clamped between the first hinge 11A and the second hinge 12A. The bag opening sealing element 15A is suitable to be made of elastic high-temperature resistant materials such as rubber and silicone. The bag opening sealing element 15A is provided with a needle slit 30A for vacuuming the inside of the food storage bag. By installing the first hinge 11A and the second hinge 12A at the opening of the food storage bag, and using the locking structure 20A to press the first hinge 11A and the second hinge 12A together, the opening of the food storage bag can be sealed, allowing the user to heat the food inside the bag in a water bath. Simultaneously, by installing the hinge sealing element 13A on the opposite surfaces of the first hinge 11A and the second hinge 12A, a better seal can be achieved at the opening of the food storage bag, preventing air leakage or external liquid from entering the bag during food cooking, thus avoiding spoilage. In cases of poor cooking results, the sealing device effectively ensures the sealing stability and sealing effect. Furthermore, by providing the insertion slit 30A on the bag opening seal 40A for vacuuming the inside of the food storage bag, the sealing device can vacuum the food storage bag through the insertion slit 30A. After vacuuming, the insertion slit 30A can automatically close using its own characteristics, thereby achieving a seal on the food storage bag. This not only effectively enhances the functional versatility of the sealing device, thus improving its practicality and applicability, but also effectively improves user convenience and user experience.

[0040] like Figures 5 to 8 As shown, the bag opening seal 15A is also provided with a temperature measuring slit 40A for inserting a food probe to measure the temperature of the food inside the preservation bag. The temperature measuring slit 40A is adapted to be spaced apart from the needle insertion slit 30A. By providing the temperature measuring slit 40A on the bag opening seal 15A spaced apart from the needle insertion slit 30A, not only can temperature measurement and vacuuming be achieved without interference, effectively improving the accuracy of temperature measurement and the efficiency of vacuuming, but it also allows users to insert the food probe through the needle insertion slit 30A and the temperature measuring slit 40A into different positions of the food to measure the temperature at different locations, avoiding differences in the food's cooking area and effectively improving the food cooking effect.

[0041] like Figures 5 to 7As shown, in an optional embodiment, one end of the first hinge 11A and the second hinge 12A are adapted to be hinged together, and the other end is adapted to be separably fastened by the locking structure 20A. By hinged one end of the first hinge 11A and the second hinge 12A together, and separably fastened the other end by the locking structure 20A, it is not only convenient for users to install and disassemble the sealing device, effectively improving user convenience, but also ensures the sealing stability of the first hinge 11A and the second hinge 12A when clamping the bag opening, effectively improving the sealing effect.

[0042] like Figures 5 to 7 As shown, in an optional embodiment, the locking structure 20 includes a snap fastener 22A disposed on one of the first hinge 11A and the second hinge 21A, and a hook 23A disposed on the other hinge that matches the snap fastener 22A. The snap fastener 22A is adapted to be detachably engaged with the hook 23A. By providing the snap fastener 22A and the hook 23A on the first hinge 11A and the second hinge 12A respectively, so that the first hinge 11A and the second hinge 12A can be detachably engaged, the connection structure of the first hinge 11A and the second hinge 12A can be simplified, thereby reducing the production cost and user cost of the sealing device. Furthermore, the disassembly and installation difficulty of the sealing device can be reduced, effectively improving user convenience.

[0043] like Figures 5 to 7 As shown, in an optional embodiment, the opposing surfaces of the first hinge 11A and the second hinge 12A are provided with relief grooves 16A that match the bag opening seal 15A, and the bag opening seal 15A is adapted to be detachably clamped in the relief grooves 16A. The clearance groove 16A is adapted to position the bag opening seal 15A. Positioning the bag opening seal 15A through the clearance groove 16A effectively reduces the installation difficulty of the bag opening seal 15A and improves user convenience. At the same time, the clearance groove 16A is also adapted to limit the bag opening seal 15A. Limiting the bag opening seal 15A through the clearance groove 16A can prevent the bag opening seal 15A from sliding freely during installation, thereby affecting the sealing effect and effectively ensuring the sealing stability and sealing effect of the sealing device. In addition, by placing the bag opening seal 15A in the clearance groove 16A, the contact area between the bag opening seal 15A and the first hinge 11A and the second hinge 12A can also be increased, thereby improving the sealing effect of the sealing device when clamped at the opening of the food storage bag.

[0044] like Figure 6As shown, in an optional embodiment, one of the bag opening seal 15A and the clearance groove 16A is provided with a limiting part 17A, and the other is provided with a limiting groove 18A corresponding to and matching the limiting part 17A. When the bag opening seal 15A is located in the clearance groove 16A, the limiting part 17A is adapted to engage with the limiting groove 18A. The limiting part 17A and the limiting groove 18A are adapted to position the bag opening seal 15A during installation. By positioning the bag opening seal 15A through the limiting part 17A and the limiting groove 18A, the installation difficulty of the bag opening seal 15A can be effectively reduced, improving user convenience. At the same time, the limiting part 17A and the limiting groove 18A are adapted to limit the installation of the bag opening seal 15A. By limiting the installation of the bag opening seal 15A through the limiting part 17A and the limiting groove 18A, the situation where the bag opening seal 15A comes out of the clamping of the first hinge 11A and the second hinge 12A during installation, resulting in sealing failure, can be effectively guaranteed to ensure the sealing stability and performance stability of the sealing device.

[0045] like Figure 6 and Figure 7 As shown, in an optional embodiment, the surfaces of the first hinge 11A and the second hinge 12A opposite to each other are provided with mounting grooves 14A corresponding to the hinge seal 13A, and the hinge seal 13A is at least partially confined within the mounting grooves 14A. The mounting grooves 14A are adapted to position the hinge seal 13A during installation. Positioning the hinge seal 13A through the mounting grooves 14A effectively reduces the installation difficulty of the hinge seal 13A, thereby reducing production and user costs. Simultaneously, the mounting grooves 14A are also adapted to limit the installation of the hinge seal 13A. Limiting the installation of the hinge seal 13A through the mounting grooves 14A prevents the hinge seal 13A from sliding during installation, thus avoiding poor sealing performance and effectively ensuring the sealing stability and sealing effect of the sealing device.
