Referring to fig. 1 and 2, in the present embodiment, the present invention discloses a cover 10 for sealing, including a sheet-shaped body 20, a sealing installation surface 14 is formed on the upper portion of the body 20, the sealing installation surface 14 surrounds a material loading opening 29, a sealing membrane 40 for closing the material loading opening 29 is laid on the sealing installation surface 14 through an adhesive layer, the inner side of the sealing installation surface 14 is connected to a lower platform 28 through a connecting portion 13, a material unloading opening 16 is arranged in the lower platform 28, a communicating cavity is formed between the lower platform 28 and the sealing membrane 40, and a container connecting portion 15 is arranged on the periphery of the sealing installation surface 14. The container connecting portion 15 is a sealing connecting portion for sealing connection with a corresponding connecting structure of a container, and as indicated by a dotted line in the figure, a container body is formed by the cover 10 and the container body together to form a cavity for containing the particulate material. When the container of filling with the material in the transportation, because jolting or toppling of container, can the material impact sealed diaphragm, owing to adopt the viscose to connect, there is sealed requirement again, so under this condition, the sealing performance who destroys sealed diaphragm will appear easily, in this embodiment, body 20 integrated into one piece has lower platform, the lower wall of platform under the material impact earlier, then, the material that the momentum reduces can get into the intercommunication cavity through material mouth down, and this part material can be preferential downstream owing to the effect of gravity, fall into the position between sealed diaphragm and the lower platform, it is showing to reduce towards material loading mouth and pushes away the sealed diaphragm and destroy its sealed power. Further through feed opening and intercommunication cavity, and through last material mouth final pouring container, to the simple material of holding, to the technical staff in the art, set up lower platform 28, feed opening 16 and intercommunication cavity and be consumptive material and processing, can avoid as far as possible. The body 20 is made of metal easy to process, and preferably made of tinplate, aluminum or aluminum alloy. The body 20 is in a sheet shape, so that a connecting structure or a mounting surface can be easily processed, and compared with a membrane laid on the body, the hardness of the body is higher, so that the body can bear higher pressure during hot-pressing. The lower platform 28 is parallel to the sealing installation surface 14 and has a certain distance with the sealing installation surface 14 in the height direction, in addition, the lower platform 28 extends horizontally to shield part of the material channel to form a material discharge opening 16 with a diameter significantly reduced than that of the container, and the bottom surface of the lower platform 28 forms a blocking surface in the pouring process. When the material is a liquid material, the liquid material can flow out from the corresponding position when the liquid material passes over the edge of the feed opening 16; the phenomenon that when the liquid is poured, a large amount of liquid can be poured out due to a small inclination angle, and the flow can not be controlled can be avoided. Thereby improving the functional attributes of the cover.

The lower platform 28 and the body 20 are integrally formed, are made of metal, have high strength, can play a role in blocking when accommodating heavy solid particle materials, and are not easily damaged by materials impacting towards the cover opening. Especially in transportation and handling operation process, the material can jolt and collide in the container, lays through the viscose layer to adopting sealed diaphragm and lid, and its diaphragm intensity is limited, especially receives the influence to the impact from inboard outside, and when the container was placed to the level, the side to side motion of packing material was appeared often, can bring the material to the repeated impact of sealed diaphragm to improve the risk of sealed face damage. Therefore, for solid materials such as granular materials, a wider lower platform 28 is especially provided to block and mitigate the impact on the sealing membrane, where wider means that the width of the lower platform is 1mm to 50 mm. In some embodiments, the sealing membrane is made of transparent materials or semitransparent materials, so that under the condition of ensuring sealing, the inner discharging port can still be seen through the sealing membrane through the hole of the feeding port, the condition of the material can be seen through the material port, the condition of the material can be seen in the sale state or the unused state after purchase, the use of a user is facilitated, and the applicability of a product of a sealing cover body manufacturer is improved.

In some embodiments of the present invention, as shown in fig. 3 and 4, the lower platform 28 is provided with a second surface facing the communicating cavity and a first surface facing the enclosed space in the container, the second surface of the lower platform 28 is provided with a second mounting surface 11, and the second mounting surface 11 is provided with a first membrane 17 for closing the opening of the material to be cut. The first membrane is provided with a through hole 21 for pouring materials, and the second mounting surface 11 is connected with a container connecting part 15 on the periphery of the body through a connecting part 13. The cover body is used for connecting the container body and forming a cavity for containing granular materials with the container body, when a user needs to pour materials for a small number of times in use, one or more through holes 21 need to be formed in the first membrane 17, the hole diameter of each through hole 21 is matched with the diameter of the current material, the diameter range of the through hole 21 is 0.2-45.5 mm, and the diameter of the through hole is larger than the diameter of the material. When the diameter of the material is larger, a larger through hole caliber is selected, and when the diameter of the material is smaller, a smaller through hole caliber is selected. Thus, when the material is poured, a small amount of the material can be poured out of the through hole 21, and the user can conveniently control the poured amount. In certain cases, a relatively large opening may be required for small granular material, such as salt pellets, and in restaurant applications, where a cook may desire to pour a specific amount of salt quickly, a relatively large opening may be provided, having a diameter of 45mm, and since the cook has a large number of practical situations, it may be easy to master the appropriate pour amount through the through hole, and in order to accommodate the cook, the diameter may be in the range of 25-45.5 mm. The diameter of the through hole 21 is larger than the diameter of the particle materials, so that the particle materials can be poured out of the through hole 21 after passing through the blanking port 16.

When laying through first diaphragm around the feed opening, first diaphragm forms barrier structure with lower platform, in the container when filling up the material in the transportation, because jolting or toppling of container, can the material impact sealed diaphragm, owing to adopt the viscose to connect, have sealed requirement again, so under this condition, the sealing performance who destroys sealed diaphragm will appear easily, in this embodiment, first diaphragm forms barrier structure with lower platform, the material strikes platform and first diaphragm downside earlier, then, only very little material can get into the intercommunication cavity through the through-hole of first diaphragm, and this part material can be preferential downstream owing to the effect of gravity, fall into the position between sealed diaphragm and the lower platform, it pushes away the power that sealed diaphragm destroyed its sealed and reduces further towards last feed opening. In some embodiments, the plurality of through holes 21 are disposed near the edge of the cover 10 and are disposed around the entire circumference of the edge of the cover 10, so that the user can randomly pick up the container body to pour the container body regardless of the current holding position; in other embodiments, the plurality of through holes 21 are located close to the edge of the cover 10 and in a certain part, so that the area of the through holes is smaller, the number of through holes is smaller, and therefore, dust is less likely to enter the container, and moist air is less likely to enter the container; in other embodiments, the diameters of the through holes 21 are different, the diameter of the through hole 21 near the edge of the cover 10 is smaller, in this embodiment, the diameter of the through hole is 6.5mm, and the diameter of the through holes near the edge of the cover is 1.5mm, so that the inclined angle of the container can be adjusted, and the pouring amount can be controlled more effectively.

In this embodiment, the first membrane 17 is made of aluminum foil or a thin film made of polymer material and having a thickness that can satisfy the requirements of strength and protection, and the corresponding products and standards are already formed in the prior art. The first membrane 17 is connected with the body through the adhesive layer on the second mounting surface 11, and because in a small amount of dumping for many times, the particle materials can impact the first membrane 17 and push the membrane outwards, the adhesive layer has larger adhesive force and adhesive area.

Here, if the breathability of the first film 17 itself is not taken into consideration, the connection is also a sealing connection surface. This aluminum alloy's first diaphragm 17 needs to pass through hot melt adhesive layer and lid close bonding, because there is granule material in the use, needs a small amount of toppling over many times, and in toppling over the in-process, the container body is toppled over, and the granule material of a large amount wherein can strike towards the lid (especially when beginning to use, granule material's volume is great, and the impact force is very big) for lid 10 relevant position department receives great impact force.

When the first film 17 is made of a polymer material, it is preferable to use a polymer organic transparent film or an organic semi-transparent film, and the adhesive layer used correspondingly is an epoxy adhesive layer, which can be combined with the organic polymer material and is tightly attached to the body of the lid 10, where the connection is also a sealing connection surface if the air permeability of the first film itself is not considered. The viscose layer here needs to provide great cohesion, because there is particulate material in the use, needs empting a small amount of many times, empting the in-process, the container body, and the many particulate material wherein can strike towards the lid (especially when beginning to use, the volume of particulate material is great, and the impact force is very big) for lid relevant position department receives great impact force. By using a transparent film or a translucent film, the user can see the inside of the container through the first film 17, and can see the amount or state of the particulate material. It is easier to find in the case of contaminated or damp caking of particulate material.

The body 20 of the cover body is made of easily processable metal, preferably tinplate, aluminum or aluminum alloy. The body 20 is the lamellar connection structure or installation face of easily processing out, and the hardness of the material of body 20 will be far greater than the hardness of first diaphragm 17 material, and under the circumstances of higher suppression temperature, the material of body 20 makes the hardness of body 20 hardly influenced moreover to under the high temperature suppression circumstances, the hardness of body material is more than the hardness of diaphragm material under the high temperature circumstances far away, makes the diaphragm more easily attached on lid body surface under the suppression power. The container connecting part 15 is arranged on the periphery of the body 20, the container connecting part 15 is thin and is bent annularly, and the container connecting part is easy to be connected with the container body in a sealing way through extrusion or deformation, so that the sealing performance of the joint of the cover body and the container is ensured.

The high-temperature pressing means that the cover body and the first membrane are heated to reach the temperature at which the polymer material can soften and deform under the condition that the cover body is made of metal and the first membrane is made of polymer material, and certain pressure is applied under the condition to attach the cover body and the first membrane. Because the high polymer materials generally soften and deform at higher temperature, the deformation temperatures corresponding to different materials can be consulted in related manuals and teaching materials, and the method is a known technical means.
