Abstract: Disclosed are systems and methods related to a valving system that can be used with containers. In some embodiments, a valving system for a bag can include an air sieve coupled to a retaining cap. A sealing part is placed between the retaining cap and the air sieve. The retaining cap can include a passage for allowing air to flow out of the bag under the action of a vacuum pump. The sealing part can include a perforation configured to allow air flow from a channel of the air sieve. A sidewall of the bag is configured with an orifice to receive part of the air sieve, and the sidewall is compressed between the retaining cap and the air sieve. When the vacuum pump is removed, atmospheric pressure pushes against the sealing part, which then seals the bag by pushing against a sealing part seat of the air sieve.

Abstract: Disclosed are systems and methods for making and using a valving system that can be used with containers. In some embodiments, a valving system for a silicone bag can include an air sieve coupled to a sidewall of the silicone bag. The sidewall of the silicone bag can include a perforation to allow outflow air out of the bag. The air sieve can include a sealing seat that is configured to cooperate with the sidewall to provide a seal that prevents external air from entering the container. Using a vacuum inducing device, air can be evacuated from the container by inducing air to flow through channels in the air sieve and out of the perforation in the sidewall.

Abstract: The present invention discloses a storage box, comprising a box body and a cover body which is covered on the top of the box body, and further comprising a partition component. The partition component comprises a first silica gel sealing strip frame, a second silica gel sealing strip frame and a hard partition plate; the inner wall of the first silica gel sealing strip frame is provided with a first groove; the first silica gel sealing strip frame is placed vertically inside the box body; the outer wall of the first silica gel sealing strip frame is attached to the inner wall of the box body; the inner wall of the second silica gel sealing strip frame is provided with a second groove; the hard partition plate is provided with third grooves on both corresponding sides near the top.

Abstract: The present invention discloses a laser radar for synchronous scanning of line exposure and point lasers of a rolling shutter door and a detection method. The laser radar comprises: a point light source rotating mechanism and an image sensor mechanism; the rotation speed of the point light source rotating mechanism is consistent with the scanning speed of the image sensor mechanism, and the phase is synchronized; and a region illuminated by lasers is in the region corresponding to the exposure line of the rolling shutter door of the image sensor mechanism. The present invention proposes the use of point laser rotating scanning in combination with line scanning of the rolling shutter door to synchronously realize the functions of line lasers.

Abstract: The present invention relates to the technical field of pizza boxes, comprising a box body and a top cover. The box body and the top cover have triangular sector structures. The top end of the box body is open, and the edge of the open end extends outward to form a clamping flange; a lower end surface of the top cover is hermetically abutted against an upper end surface of the clamping flange; the side wall of the top cover is hinged with a plurality of claw buckles along a circumferential direction; the claw buckles have clamping plates and are clamped with the lower end surface of the clamping flange; and the bottom of the box body and the edge of the top cover are wrapped with heat insulation layers. The heat insulation pizza box of the present invention has good sealing and heat insulation effects.

Abstract: An adsorptive anti-tipping device and a cup body matched therewith, being used to fasten the cup body to prevent it from tipping, including a driving rod, which driving rod comprises a sliding rod, a limit rod and an abutment rod, the limit rod is vertically fixed on the upper end of the sliding rod; the abutment rod is fixedly connected with one end of the sliding rod; on a fixed cover is arranged a sliding positioning hole, and the limit rod is limited above the fixed cover; the suction component is slidably clamped with the fixed cover, and has a driving slope and a driving block on it, the driving block corresponds to the position of the adsorptive surface of the suction component,. The present application is simple in structure and easy to use. Using a suction cup to adsorb the surface, the present application may prevent containers' tipping.
