The invention relates to a drinking lid (10) for drinking containers (12) comprising a funnel-like, circumferential drinking edge (14), which is open to the drinking container (12), having a fasteningsection (16) for fastening the drinking lid (10) to an edge region surrounding an opening of the drinking container (12), and a bowl-shaped, elastic gasket (20), which can be inserted into the drinking edge (14), for sealing the drinking edge (14). The gasket (20) circumferentially contacts the drinking edge (14) in the region of the free end of the drinking edge (14), when the drinking lid (10)is properly installed on the drinking container (12), forming an intermediate chamber (22) which is open to the drinking container (12), and is designed such that it can be partially raised from the drinking edge (14) by a suction action of a user of the drinking lid (10), in order to free a passage to the intermediate chamber (22). The gasket (20) has, in the region of the base thereof, an outwardly protruding circumferential flange (26), which is designed to contact the edge surrounding the opening of the drinking container (12), and the drinking edge (14) has a clamping flange (32), which projects toward the gasket, in order to clamp the flange (26) of the gasket (20) against the edge of the opening of the drinking container (12) as the drinking lid (10) is fastened to a drinking container (12), the flange (26) of the gasket (20) having a number of openings (28) to the intermediate chamber (22), with the clamping flange (32) ending before the openings (28) provided in the flange (26) of the gasket (20).

The invention discloses a glycerin application error prevention control method, device and system. Wherein, when it is detected that the filter rod forming machine is in the running state, it is detected whether the glycerin application device is in the closed state; if the glycerin application device is in the closed state, then query whether the first timer has been started; if the first timer has not been started, then Start the first timer, so that the first timer starts counting, and instructs the alarm device to give an alarm, and then performs the step of detecting whether the glycerin application device is in a closed state; if the first timer has started, then judge the timing of the first timer Whether the time reaches the first delay time; if the timing time has not reached the first delay time, then perform the step of detecting whether the glycerin application device is in the closed state; if the timing time reaches the first delay time, then close the first timer , instruct the alarm device to stop the alarm, and instruct the filter rod forming machine to stop. Thereby, it can effectively prevent unqualified filter rods from flowing into the next process.

The invention discloses a gas recycling type injection mold. The gas recycling type injection mold comprises a bottom die (1) and a top die (2). The gas recycling type injection mold is characterized in that a feeding opening (3) used for filling injection material is formed in the top die (2), and is fixedly connected with a feeding pipe (4); the feeding pipe (4) comprises a vertical pipe (5), an inclined pipe (6) and a degassing device (8); the degassing device (8) is connected with the vertical pipe (5) and the inclined pipe (6); a degassing hole (10) is also formed in the upper surface of the degassing device (8) and is connected with a gas recycling device. The gas recycling type injection mold has a degassing function, is good in degassing effect and further has a gas recycling function.

The invention discloses a degassing type injection mold. The degassing type injection mold comprises a bottom die (1) and a top die (2). The degassing type injection mold is characterized in that a feeding opening (3) for filling injection material is formed in the top die (2) and is fixedly connected with a feeding pipe (4); the feeding pipe (4) comprises a vertical pipe (5), an inclined pipe (6) and a degassing device (8); the degassing device (8) is connected with the vertical pipe (5) and the inclined pipe (6). According to the degassing type injection mold, by arranging the degassing device, the injection material is degassed before injection molding, so that the condition that no air bubble is generated in the surfaces and the insides of formed plastic parts can be ensured; especially for some plastic parts which has high requirement on processing accuracy and are free of air bubbles, the quality fully meets the standard, the finished product ratio and the production efficiency of the plastic parts are improved.

The invention relates to a water channel fin welding structure and a welding method. A connecting part between each water channel fin and a corresponding water channel hopper is a welding area (27). Each water channel fin is divided into three parts, namely a water channel fin first area (22), a water channel fin second area (25) and a water channel fin third area (26) through a first pressing rib (23) and a second pressing rib (24), wherein the water channel fin first area (22) is located between the water channel fin second area (25) and the water channel fin third area (26), one end of the first pressing rib (23) and one end of the second pressing rib (24) have an intersection point or an intersection position, and the intersection point or the intersection position is located in the corresponding welding area (27). By means of the water channel fin welding structure and the welding method, the coinciding section of one area of each water channel fin and the corresponding welding area is limited to be the minimum through the corresponding pressing ribs so that heat generated during welding can only cause deformation changes of the corresponding two areas beside, the deformation degree of each middle area is the minimum and can be ignored, and therefore a slope structure of each middle area cannot be damaged, and it is ensured that accumulated water can flow into a water channel from the middle areas.
