Referring to fig. 1 to 2, in the present embodiment, the present invention discloses a lid 10 for pouring out particulate material, including a lamellar body 20, wherein the dotted line indicates a container body, and a cavity for accommodating the particulate material is formed by the lid 10 and the container body. The body 10 has a first surface facing the space enclosed in the container (such as the lower side of the body 20 in the figure) and a second surface facing the outside of the container (such as the upper side of the body 20 in the figure), a material port 16 is arranged in the middle of the body 20, a second mounting surface 11 is arranged on the second surface and surrounds the material port, a first membrane 17 covering the material port is laid on the second mounting surface 11 through an adhesive layer, a plurality of through holes 21 are arranged on the first membrane, and the second mounting surface 11 is connected with the container connecting part 15 on the periphery of the body through a cover connecting part 13. The cover body 10 is used for connecting the container body, and forms a cavity for containing the granular material with the container body, when a user needs to pour the material for a small amount of times in use, a plurality of through holes 21 need to be arranged on the first membrane, the diameters of the through holes 21 are matched with the diameter of the current material, and the diameter range of the through holes 21 is 0.2-16.5 mm. 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. The aperture of the through hole 21 is larger than the diameter of the granular material, and in this embodiment, the apertures of the through holes are all 3.5mm, so that the granular material can be poured out of the through hole 21 after passing through the material port 16.

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 21 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 than the diameter of the other through holes 21, in this embodiment, the diameter of the through hole is 6.5mm, and the diameter of the through holes in two rows near the edge of the cover is 1.5mm, so that the amount of pouring per time can be more effectively controlled by adjusting the inclined angle of the container.

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 at the second mounting surface 11 through the adhesive layer 18, and the adhesive layer 18 has larger adhesive force and adhesive area because particle materials impact the first membrane 17 and push the membrane outwards in a small amount of pouring for many times. When first diaphragm 17 adopted the aluminium alloy membrane, the viscose layer that its correspondence adopted is the hot melt adhesive layer, and in the pressing process, through the problem that heats when improving the suppression for the hot melt adhesive layer promptly with lid zonulae occludens, simultaneously with second installation face 11 zonulae occludens. Here, the connection is also a sealing connection surface if the breathability of the first film sheet itself is not taken into account. This first diaphragm of aluminum alloy need be through hot melt adhesive layer and lid zonulae occludens, 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 wherein many granule material can be towards the lid impact (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, and if the air permeability of the first film 17 itself is not considered, the connection is also a sealing connection surface. The adhesive layer herein needs to provide a larger bonding force, because there is a small amount of particulate material that needs to be poured many times in the using process, and in the pouring process, the container body is poured, and a large amount of particulate material therein will impact towards the lid 10 (especially, when beginning to use, the amount of particulate material is larger, the impact force is very large), so that the corresponding position of the lid 10 receives a larger 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 lid 10 is made of easily machinable 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 hardly influenced moreover to under the high temperature suppression circumstances, the hardness of the material of body 20 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 portion 15 is disposed on the periphery of the main body 20, and the container connecting portion 15 is thin and bent in a ring shape, so as to be easily connected to the container main body by extrusion or deformation, thereby ensuring the sealing performance of the connection portion between the lid 10 and the container.

The high-temperature pressing means that, when the cover 10 is made of a metal material and the first membrane is made of a polymer material, the cover and the first membrane 17 are heated to a temperature at which the polymer material can be softened and deformed, and a certain pressure is applied to attach the cover 10 and the first membrane 17. 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.

Further, as shown in fig. 1 and 2, a cover 10 for pouring out particulate material includes a cover connecting portion 13, the cover connecting portion 13 is bent toward the inside of the container, a round corner is formed between the second mounting surface 11 and the cover connecting portion, a first membrane 17 is disposed on the second mounting surface 11, and the first membrane 17 has a peripheral membrane which exceeds the first mounting surface and forms a mounting surface attached to the round corner under a high-temperature pressing condition. The initial first film 17 is a plane layer with equal thickness before being pressed, the hardness of the first film 17 is reduced by high-temperature pressing, the pressing surface is in a corresponding round corner shape at the second mounting surface 11 and the cover body connecting part 13, so that the peripheral film part of the first film 17 is deformed and attached to the corresponding round corner of the cover body or is also attached to the cover body connecting part 13, and the first film 17 forms a mounting surface attached to the round corner under the condition of high-temperature pressing. In this embodiment, the temperature of the high-temperature pressing is at least higher than the lowest temperature that causes the creep deformation of the film material, and the temperature range of the high-temperature pressing is 110 to 350 degrees according to the material, and for a good attaching effect, a higher temperature can be selected to achieve, in this embodiment, the main body of the adhesive layer material is epoxy resin, the main body of the film material is a transparent polymer organic material, and when the extrusion pressure is 120 degrees to 240 degrees, and the extrusion pressure is 320KG to 488KG, the adhesive layer and the film are bonded, and the film is attached to the rounded corner surface of the cover body through the adhesive layer, which has a good effect, particularly, the pressing surface is a rounded corner shape corresponding to the first mounting surface and the cover body connecting portion 13, so as to improve the bonding strength at the rounded corner, and therefore, in a specific case, such as in the production or use process, the pressures on the upper and lower sides of the first film 17 are not equal, especially, when the upper side pressure is greater than the lower side pressure, the protection effect is better. Due to the deformation effect of the first membrane in high-temperature pressing, the shape of the first membrane is changed correspondingly and is tightly attached to the body, and accordingly the attaching reliability is improved.

As shown in fig. 1 and 2, the utility model discloses a lid 10 for pouring out granule material, this lid 10 includes lamellar body 20 to be equipped with lid connecting portion 13 in the periphery of body 20, this connecting portion 13 is buckled towards the container outside, and first diaphragm 17 passes through the viscose layer and sets up on second installation face 11, is equipped with material mouth 16 at the middle part of body 20, and first diaphragm 17 covers this material mouth.

When the bending ring is formed by pressing a body, the bending ring is formed by a one-time process or a distribution process, the bending ring surrounds the material port, under the condition that the first membrane 17 is pressed at a high temperature, the adhesive layer is arranged at the lower layer of the first membrane 17, because the melting conditions of the membrane layer and the adhesive layer are different, and the flowing properties are different, the annular combination groove 18 with the large and small section is adopted, the membrane layer and the adhesive layer can be favorably deep into the bottom of the annular combination groove 18, in addition, the pressing process lasts for a certain time, such as more than 5 seconds, the mixed layer of the membrane layer and the adhesive layer can be attached to the bottommost surface and the wall surface with the large and small upper part of the annular combination groove 18 under the condition of high temperature and high pressure, a stable combination surface is formed, and after cooling, good attachment and stability can be kept. For the case that the film is gradually reduced in the pressing direction, such as the case that the film is smaller and larger in cross section, the inventor verifies through experiments that there is a high probability that the mixed layer of the film layer and the adhesive layer cannot be sufficiently contacted with the bottom surface of the annular combination groove 18 and form a stable combination surface, and since the upper part of the rear surface is smaller, the tensile force generated in the structure is also smaller, the local strength of the ring is easy to be insufficient, and in order to be capable of sufficiently contacting, a long time, such as more than 15 seconds, is required, so that the actual cross-section combination (the first film 17 and the second mounting surface 11 in the embodiment) causes the first film to extend outwards due to the overlong pressing time, thereby reducing the thickness of the first film forming the film at the effective covering material opening and the second mounting surface 11, and further reducing the strength of the film.

As shown in fig. 3, the utility model discloses a lid 10 for pouring out granule material, this lid 10 include lamellar body 20 to be equipped with lid connecting portion 13 at the body, this lid connecting portion 13 is buckled towards the container inboard, is equipped with first installation face 19 in first face, and first diaphragm 17 passes through the viscose layer and sets up on first installation face 19, is equipped with material mouth 16 at the middle part of body 20, and first diaphragm 17 covers this material mouth. A bending ring is formed on the inner ring of the first mounting surface 19, an annular combination groove 18 with a small section and a big section is formed between the bending ring and the first mounting surface 19, and the first diaphragm 17 forms a mounting surface which is pressed into the annular combination groove 18 and attached under the condition of high-temperature pressing. When the bending ring is formed by pressing a body, the bending ring is formed by a one-time process or a multi-step process, the bending ring surrounds the material port, under the condition that the first membrane 17 is pressed at high temperature, the adhesive layer is arranged on the upper layer of the first membrane 17, the melting conditions of the membrane layer and the adhesive layer are different, and the flowing properties are different, the annular combination groove 18 with a small lower part and a large upper part is adopted, the section is a groove which is gradually enlarged along the pressing direction, the film layer and the adhesive layer can be favorably extended into the bottom of the annular combination groove 18, in addition, the pressing process lasts for a certain time, for example, more than 5 seconds, under the condition of high temperature and high pressure, the mixed layer of the membrane layer and the adhesive layer can be attached to the bottommost surface and the wall surface with the small upper part and the large lower part of the annular combination groove 18, and a stable combination surface is formed, and after. For the case of small and large cross section, the inventor verifies through experiments that there is a high probability that the mixture layer of the film layer and the adhesive layer cannot be sufficiently contacted with the bottom surface of the annular bonding groove 18 and form a stable bonding surface, and since the upper portion of the rear surface is small, the tensile force generated in the structure is small, the local strength of the annular shape is easy to be insufficient, and in order to be able to sufficiently contact, a long time, for example, more than 15 seconds, is required, so that the actual cross section bonding (in this embodiment, the first film 17 and the first mounting surface 19) causes the first film 17 to extend outwards due to the too long pressing time, thereby reducing the thickness of the first film 17 forming the film at the effective covering material opening and at the second mounting surface 19, and further reducing the strength of the film.

Further, as shown in fig. 3, the through holes 21 on the first membrane 17 on the cover are uniformly distributed on the first membrane 17, and the through holes 21 can be poured out when the cover is poured in any direction, so that a user who does other operations at the same time can have better experience because the user can pour the granular materials at each angle. In another embodiment, the plurality of through holes 21 of the first membrane 17 of the cover are only present at a local location near the junction of the first membrane 17 and the corresponding mounting surface, where the plurality of through holes 21 facilitate the emptying of the remaining particulate material from the container. Meanwhile, the number of the through holes can be reduced by arranging the through holes 21 at local positions, so that the moisture or dust pollution is reduced.

Further, as shown in fig. 3, as another embodiment, a lid 10 for pouring out particulate material is disclosed, which comprises a sheet-like body 20, wherein the dashed line indicates a container body, and a cavity for containing the particulate material is formed by the lid 10 and the container body. The body 10 has a first surface facing the space enclosed in the container (such as the lower side of the body 20 in the figure) and a second surface facing the outside of the container (such as the upper side of the body 20 in the figure), a material port 16 is arranged in the middle of the body 20, a first mounting surface 19 is arranged on the first surface around the material port, a first membrane 17 covering the material port is laid on the first mounting surface 19 through an adhesive layer 18, a plurality of through holes 21 are arranged on the first membrane, and the first mounting surface 19 is connected with the container connecting part 15 on the periphery of the body through a cover connecting part 13. The cover 10 is used for connecting and forming a cavity for containing granular materials with the container body, when a user needs to pour the materials for a small amount of times in use, a plurality of through holes 21 need to be formed in the first membrane 17, so that the materials can be poured out from the through holes 21 for a small amount when being poured, and the user can control the pouring amount conveniently. The first membrane 17 is made of an aluminum foil or a high polymer material and is a thin film with a certain thickness, the first installation surface 19 is connected with the body 20 through an adhesive layer, particle materials impact the first membrane 17 in a small amount of dumping for multiple times and push and pull the membrane outwards, and at the position corresponding to the first installation surface 19, the impact force applied to the first membrane 17 can be reduced due to the fact that the impact of the particle materials is pressed to the first membrane 17 and the first installation surface 19, and therefore the anti-impact performance is more reliable. Since the first mounting surface 19 is on the surface pressed by the particulate matter, the pressing influence on the first diaphragm 17 is smaller than that of the second mounting surface 11, thereby improving the mounting reliability. In the design and the production of reality, the engineer often can be the diaphragm design in the one side towards the container outside, thinks such processing could realize to and when the diaphragm is transparent, just so can see inboard granule material, nevertheless, process the utility model discloses a reverse thinking of inventor discovers to adopt the diaphragm setting in one side of lid body 20 towards the container in, can not increase the degree of difficulty of processing in the course of working, can be more reliable when granule material strikes first diaphragm 17 in the use simultaneously, and actual need's the area of installation face is littleer, can not influence when the diaphragm is transparent, observes the condition of inside granule material.
