[0031] Embodiment 1

[0032] like Figure 1 The structure diagram of a portable container with an opening and closing lid is shown, comprising:

[0033] Container body 1; the container body 1 can be used to hold various objects. In this embodiment, the container body 1 is used to hold traditional snacks such as sour food; in order to facilitate customer observation, the container body 1 is made of a transparent material, which can be plastic or glass; of course, in other occasions where observation is not required, metal or other materials can also be used; for the convenience of processing, the material in this embodiment is an acrylic plate;

[0034] A plurality of container covers 2; the container covers 2 are installed on the opening of the container body 1 in a manner of being evenly distributed around the circumference, forming a lotus shape to be opened or closed; a radial support tube 3 is provided on the outer side of each container cover 2, one end of the support tube 3 points to the center point of the container body 1, and the other end is close to the midpoint of the edge of the container cover 2, which is used to drive the container cover 2 to flip up and down;

[0035] An air filling tube 5 is provided on the outer surface of the container body 1 at a position corresponding to the support tube 3; the air filling tube 5 is connected to the support tube 3 through a hose 4; a connected air cavity is formed inside the support tube 3, the hose 4 and the air filling tube 5; when the air cavity is filled with high-pressure gas, the hose 4 is in a straight state under the gas pressure, and the support tube 3, the hose 4 and the air filling tube 5 are coaxial, at this time, the container cover 2 is in an upright state under the driving action of the support tube 3, and some container covers 2 are opened in a lotus-like state, so that consumers can eat the sour food in the container body 1; when the air pressure in the air cavity decreases, the container cover 2 drives the support tube 3 to fall under the action of gravity to achieve a closing effect;

[0036] The pressure regulating device 6 is connected to the inflation tube 5 and is used to change the gas pressure in the inflation tube 5, thereby switching the hose 4 between a straight or curved shape.

[0037] This solution prevents the cover from falling and touching the food in the container, thereby reducing the risk of cross contamination, ensuring the hygiene and safety of the food, and reducing the number of operating steps, which can effectively improve the consumer's purchasing experience.

[0038] In a specific implementation, the support tube 3, the inflation tube 5 and the hose 4 adopt a flat structure to reduce the left-right shaking degree of the container cover 2 caused by the softness of the hose 4 and increase the position accuracy of the container cover 2 when it falls back.

[0039] In a specific implementation, an L-shaped reed is provided on the upper side of the air cavity, or the L-shaped reed is buried in the wall of the hose 4 on the upper side of the air cavity; the size structure of the L-shaped reed is adapted to the shape of the upper side of the air cavity when the container cover 2 is closed, so as to increase the rebound force and position accuracy when the container cover 2 falls back.

[0040] In a specific implementation, the L-shaped spring piece is used with no less than two pieces. In this embodiment, two pieces are used, one on each side. The size and width of the specific spring piece can be set according to the required elastic force. At the same time, the L-shaped spring piece can also support the container cover 2 when it falls back and closes, so that the container cover 2 falls back excessively to open the container mouth in the reverse direction.

[0041] In specific implementation, Figure 2 As shown, the pressure regulating device 6 in this embodiment adopts the structure of an extrusion ring; the extrusion ring is rotatably mounted on the container body 1 and the inflation tube 5; a through groove 632 is provided on the extrusion ring at a position corresponding to the inflation tube 5; guide slopes 633 are provided on both sides of the through groove 632, which are used to rotate the extrusion ring to gradually increase the extrusion force on the inflation tube 5. Further, in order to achieve the effect of squeezing the inflation tube 5 to change the air pressure in the hose 4, the inflation tube 5 needs to be made of a soft material, and in this embodiment, a rubber material is used, or the upper part of the inflation tube 5 is made of a hard material to support the hose 4, and the lower part that is squeezed is made of a soft material to facilitate squeezing and changing the air pressure of the air cavity. When the container cover 2 falls to close the container mouth, the inflation tube 5 is just located in the through groove 632 of the extrusion ring. At this time, the inflation tube 5 is not squeezed, and the hose 4 is in a bent state driven by the container cover 2 due to insufficient pressure. When the extrusion ring is rotated, the guide slopes 633 on both sides of the through groove 632 gradually squeeze the inflation tube 5 as it rotates, the volume of the inflation tube 5 becomes smaller, and the gas flows to the hose 4. Since the air cavity is a closed space, the gas pressure at the hose 4 gradually increases, and the hose 4 gradually straightens from a bent state, and the support tube 3 also stands upright with the container cover 2, thereby achieving the effect of opening the container mouth.

[0042] In the specific implementation, in order to facilitate the operation and achieve the effect of one-handed operation, the squeezing ring includes an upper squeezing ring 61 and a lower squeezing ring 62 which are symmetrically arranged; an upper shifting block 631 and a lower shifting block 641 are respectively arranged on the upper squeezing ring 61 and the lower squeezing ring 62; the upper shifting block 631 and the lower shifting block 641 are staggered. In this way, when it is necessary to open the container cover 2, as long as the thumb and index finger of one hand are placed on the upper shifting block 631 and the lower shifting block 641 at the same time, and then the fingers work together to pinch the two shifting blocks to the same axis. In this process, the upper squeezing ring 61 and the lower squeezing ring 62 rotate in opposite directions, respectively squeezing the inflation tube 5 and lifting the container cover 2. This structure is not only convenient to operate, but also has better output.

[0043] In a specific implementation, the pressure regulating device 6 also includes an upper fixed ring 63 fixed above the upper extrusion ring 61 and a lower fixed ring 64 below the lower extrusion ring 62. The upper fixed ring 63 and the lower fixed ring 64 are used to form a rotating track to prevent the extrusion ring from moving up and down.

[0044] Furthermore, in order to cooperate with the extrusion effect of the extrusion ring, the container body 1 is cylindrical, so that the distance between each part of the extrusion ring and the container body 1 is constant, ensuring that the extrusion can achieve the expected effect.

[0045] Furthermore, the container cover 2 adopts a fan-shaped structure, so that the arc edge of the container cover 2 fits better with the wall of the container body 1, while not protruding too much and occupying space.

[0046] Embodiment 2

[0047] like Figure 3 As shown, the difference between this embodiment and the first embodiment is that the pressure regulating device 6 adopts an automated mechanism, specifically including an air compressor 9, a pressure regulating valve 8 and a controller; the air compressor 9 is connected to the inflation pipe 5 through a pipeline 7; a pressure regulating valve 8 is provided on the pipeline 7 to control the air pressure entering the inflation pipe 5; the controller is connected to the pressure regulating valve 8 to control the action of the pressure regulating valve 8.

[0048] Furthermore, the pressure regulating device 6 also includes a button; the button is arranged on the container body 1 and connected to the controller to issue a control instruction to the controller.

[0049] When consumers want to eat sour food, they only need to press a button by hand to send a command to the controller, and the controller will control the pressure regulating valve 8 to open, so that the compressed air of the air compressor 9 enters the hose 4 to support the container cover 2. After the consumer takes the food, he presses the button again to send a command to the controller, and the controller controls the pressure regulating valve 8 to close or connect the circuit to release or directly extract the air in the hose 4, so that the container cover 2 falls back and closes. Specifically, because the air flow sound is relatively loud when the pressure regulating valve 8 is in action, the pressure regulating valve 8 can be installed far away from the container, or the pressure regulating valve 8 can be wrapped with sound-proof cotton to make it silent during operation, thereby improving the customer experience.

[0050] Embodiment 3

[0051] The difference between this embodiment and the second embodiment is that the button for sending instructions to the controller is replaced by a position sensor 10; the position sensor 10 is installed at the upper end of the container body 1 facing forward and is electrically connected to the controller to detect whether someone is standing in front of the container body 1. When someone stands in front of the container, it is assumed that the type of food placed in front is more interested. When the controller receives the signal from the position sensor 10, it controls the corresponding container cover 2 to open, which can make it easier for consumers to observe the food in the container. At the same time, the corresponding food can be extracted without pressing a button, and the experience is more convenient and smooth.

[0052] Furthermore, the container body 1 is cylindrical or polygonal.

[0053] This product is used in the retail link of sour food sales, and is also suitable for other occasions that require automatic opening and closing of the lid, such as supermarkets, convenience stores, food specialty stores, etc. Since the sale of sour food needs to increase its convenience and satisfy consumers' shopping experience of easily selecting sour food without the assistance of store staff, the automatic opening and closing of the lid container speeds up the sales process, reduces the waiting time of customers, and improves the efficiency of the retail link.

[0054] The flat surface of the container lid can be designed with a concave arc structure, that is, the flat surface is concave downward when closed; when opened upward, it can be designed to open the lid at 120 degrees. When the lid is fully opened, it provides consumers with a full range of viewing angles and space for eating, and they can easily take food from all angles. It is suitable for different kinds of sour food, whether it is large pieces of root vegetables or small leaves, they can all be easily taken out, greatly satisfying the self-selection needs of consumers.

[0055] Containers with automatic opening and closing lids avoid the disadvantage of traditional containers that require manual opening and closing of lids. Because the lid and container are separated, the lid may be placed in an unhygienic manner. They provide a clean and convenient self-service purchasing method, enhance the customer's shopping experience, and thus improve customer satisfaction.

[0056] Mainly for the food packaging industry. The innovation of this container is that it can automatically open and close the lid, which effectively solves the inconvenience of consumers having to manually open the lid in the traditional sales method of sour food packaging container body and lid body being separated, and significantly improves the safety of food during the sales process. Through this design, not only the consumer's purchasing experience is optimized, but also the risk of food contamination is reduced by reducing the direct contact of the lid with foreign objects, thereby ensuring food safety and hygiene standards.

[0057] The sour food sold is placed in a transparent container with an automatically openable and closed lid. When consumers directly see the delicious sour food through the transparent container and reach out to one of the sour food containers with clean and hygienic chopsticks or spoons, the lid of the container will automatically open 120 degrees upwards, and the consumer takes the sour food in the container. After taking it out, the lid will automatically close. The container includes a transparent container body and an automatic opening and closing lid system. The container body is made of food-grade materials to ensure the safety and display effect of the sour food during storage. The transparent design allows consumers to intuitively see the color, state and freshness of the sour food, which increases the attractiveness of purchase. The container lid is equipped with an advanced sensor that can detect the consumer's approach or contact action and trigger the opening action. When the consumer has finished taking it, the lid can be automatically closed. The lid body is fully opened 120 degrees upwards, and will not touch the food when it is opened. First, it can prevent the lid body from falling and touching and contaminating the food in the container, reducing the risk of cross contamination and ensuring the hygiene and safety of the food. Secondly, the 120-degree opening angle provides consumers with a spacious operating interface, allowing them to easily take food from the container with chopsticks, spoons or hands. The lid adopts the bionic principle to imitate the opening of a lotus. When it senses the consumer's approach or touch, the various components of the lid unfold, just like a lotus slowly blooming. After taking the food, the lid will automatically close slowly and return to its initial closed state. The automatic lid opening and closing system adopts a low-energy design and is only activated when consumers need it, effectively saving energy.

[0058] The present application provides a portable container with an opening and closing lid, comprising: a container body; a plurality of container lids; the container lids are installed on the opening of the container body in a circumferentially evenly distributed manner; a radial support tube is provided on the outer side of each container lid, which is used to drive the container lid to flip up and down; an inflation tube is provided on the outer side of the container body at a position corresponding to the support tube; the inflation tube is connected to the support tube through a hose; a connected air cavity is formed inside the support tube, the hose and the inflation tube; a pressure regulating device; the pressure regulating device is connected to the inflation tube, which is used to change the gas pressure in the inflation tube, thereby switching the hose between a straight or curved shape. This prevents the lid from falling and touching the food in the container, reduces the risk of cross contamination, and ensures the hygiene and safety of the food.
