Abstract
Description
Technical Field
[0001] This application relates to the field of glass container technology, and in particular to a glass container and a method for processing the glass container. Background Technology
[0002] Glass containers are commonly used in daily life, widely applied for beverage storage, food preservation, and chemical reagent storage. Due to their high transparency, chemical stability, and resistance to reaction with their contents, glass containers are widely favored.
[0003] However, in daily life, glass bottles often break due to sudden exposure to high temperatures. For example, accidentally placing glass containers near a stove while cooking, exposing them to direct sunlight in summer, or sterilizing wine bottles with hot water can all cause a large temperature difference between the inside and outside of the glass container, which in turn increases the internal pressure of the glass container. When this pressure exceeds the glass's tolerance limit, the glass container will break. Summary of the Invention
[0004] Therefore, it is necessary to provide a glass container and a processing method for the glass container to address the problem that glass bottles often break when suddenly exposed to high temperatures.
[0005] A glass container, the glass container comprising:
[0006] Two first wall blocks are arranged at intervals along a first direction.
[0007] Two second wall blocks are respectively disposed on both sides of each first wall block in the second direction. The two second wall blocks and the two first wall blocks enclose a container cavity. The maximum width of the container cavity in the second direction is a; the maximum width of the container cavity in the first direction is b, and a is greater than b.
[0008] In this embodiment, at least one of the surfaces of the first wall block extends outward toward the container cavity to form a protrusion, the protrusion extending on the surface of the first wall block in a U-shape or forming a closed shape with the ends connected.
[0009] In one embodiment, the ratio of the surface area of the first wall block to the surface area of the second wall block is between 2 and 10.
[0010] In one embodiment, the outer surface of the protrusion is configured as an arc surface;
[0011] And / or, the outer surface of the first wall block has a planar portion connected to the protrusion, and the protrusion and the planar portion transition smoothly.
[0012] In one embodiment, the protrusion extending beyond one end of the planar portion has a first contour line.
[0013] The protrusion and the planar portion are connected to form a second contour line and a third contour line, respectively, and the first contour line is located between the second contour line and the third contour line;
[0014] The closest distance between the first contour line and the second contour line in the third direction is c, and the closest distance between the first contour line and the third contour line in the third direction is d. c is greater than d, and the third direction is perpendicular to both the first direction and the second direction.
[0015] In one embodiment, the ratio of c to d is between 2 and 5.
[0016] In one embodiment, when the protrusion is U-shaped, the diameter of the opening of the U-shape is e, and the maximum width of the U-shape in the second direction is f, where e = 1 / 3f - 2 / 3f.
[0017] In one embodiment, the thickness of the first wall block in the first direction is g, and the thickness of the second wall block in the second direction is h, where g = 0.33 mm - 2 mm, and / or h = 0.33 mm - 2 mm.
[0018] In one embodiment, the thickness of the second wall block in the second direction is h, and the closest distance between the periphery of the pattern formed by the protrusion and the edge of the first wall block in the second direction is i, where i ≥ 2h.
[0019] In one embodiment, the glass container further includes a bottom wall block disposed on one side of each of the first wall blocks and each of the second wall blocks in a third direction, and the bottom wall block, the two first wall blocks and the two second wall blocks surround to form a container cavity;
[0020] The thickness of the bottom wall block in the third direction is k, and the closest distance between the outer perimeter of the pattern formed by the protrusion and the bottom wall block in the third direction is j, where j≥2k.
[0021] In one embodiment, the two first wall blocks, the two second wall blocks, and the bottom wall block 12 are interconnected by welding.
[0022] In one embodiment, the protrusion includes two protrusions, each of which extends in a U-shape. One of the protrusions is located inside the U-shape formed by the other protrusion. Each protrusion has two ends spaced apart along a second direction at the opening of the U-shape it forms, and the ends of each protrusion are connected to the ends of the other protrusion.
[0023] In one embodiment, the surface of the first wall block also has a reinforcing portion protruding outward toward the container cavity, the reinforcing portion being located between two protrusions.
[0024] In one embodiment, the protrusions include a plurality of protrusions, each of which surrounds a closed shape, and the closed shapes formed by all the protrusions are sequentially nested.
[0025] In one embodiment, the connecting surface between the various protrusions is an arc surface.
[0026] A method for processing a glass container, comprising the steps described in any of the preceding claims:
[0027] Two first wall blocks, two second wall blocks, and one bottom wall block are provided;
[0028] Two first wall blocks, two second wall blocks, and one bottom wall block are placed in the welding cavity of the welding mold. The inner contour shape of the welding cavity matches the outer contour shape of the glass container, so that the two first wall blocks, two second wall blocks, and one bottom wall block are respectively attached to the inner surface of the welding cavity, thereby splicing them together to form an initial container.
[0029] The welding mold containing the initial container is placed in a high-temperature device, and high-pressure gas is introduced into the container cavity so that the initial container is pressed tightly against the inner surface of the welding cavity under the action of the high-pressure gas, and the two first wall blocks, two second wall blocks and one bottom wall block are fused together under the heating action of the high-temperature device.
[0030] The initial container inside the welding mold is cooled to allow the welded initial container to set and form the glass container.
[0031] Open the welding mold to remove the glass container.
[0032] In the aforementioned glass container, when exposed to high temperatures, the internal liquid or gas will expand. The expansion force generated by the liquid or gas will act on the middle of the two first wall blocks. If the first wall blocks have protrusions, the expansion force will act on the interior of the U-shaped protrusions. At this time, due to the presence of the protrusions, the middle and top of the first wall blocks will bend outwards around the apex of the protrusions, allowing the middle of the first wall blocks to expand outwards as the pressure of the liquid or gas inside the container increases. This enables the first wall blocks to adapt to the expansion of the liquid or gas, effectively reducing the likelihood of the glass container breaking. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0053] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0056] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0057] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0058] See Figure 1 and Figure 2 The present application provides a glass container comprising two first wall blocks 10, two second wall blocks 11, and a bottom wall block 12. The two first wall blocks 10 are arranged along a first direction X, and the two second wall blocks 11 are arranged at intervals along a second direction Y, and are respectively located on both sides of the two first wall blocks 10 in the second direction Y. The bottom wall block 12 is respectively located on one side of each first wall block 10 and each second wall block 11 in the third direction Z.
[0059] In practical use, the third direction Z can be vertical, meaning the bottom wall block 12 can serve as the bottom of the entire glass container, allowing the two first wall blocks 10, two second wall blocks 11, and the bottom wall block 12 to enclose and form the container cavity 13 of the glass container. The container cavity 13 can be used to store liquids, such as wine. Furthermore, each of the first wall blocks 10 and each of the second wall blocks 11 can enclose the bottle mouth of the glass container at the end away from the bottom wall block 12. The bottle mouth is connected to the container cavity 13 in the glass container, allowing liquids such as wine to be injected into the container cavity 13 through the bottle mouth. The first glass container typically also includes a bottle cap located at the opening, thereby sealing the glass container with the bottle cap.
[0060] The thickness of the container cavity 13 in the second direction Y is the maximum width a; the maximum width of the container cavity 13 in the first direction X is b, where a is greater than b. That is, the glass container is narrow in the first direction X and wide in the second direction Y. Compared with a cylindrical glass container, the glass container that is narrow on one side and wide on the other side can save storage space while ensuring the same capacity.
[0061] When the glass container is suddenly exposed to a high temperature environment, the gas or liquid (hereinafter referred to as gas-liquid) inside the container cavity 13 will expand due to heat in a sealed state. Since the width of the container cavity 13 in the second direction Y is greater than the width in the first direction X, the two inner walls of the container cavity 13 in the first direction X have a larger area, resulting in more expansion force generated by the gas and liquid on the two inner walls. That is, the expansion force generated by the gas and liquid will be mainly concentrated in the middle of the two first wall blocks 10. If the time is too long and the temperature is too high, the first wall block 10 may break.
[0062] For this purpose, at least one surface of the first wall block 10 extends outward toward the container cavity 13 to form a protrusion 30. "At least one" means that in two first wall blocks 10, only one first wall block 10 may have a protrusion 30 on the side facing away from the other first wall block 10, or each of the two first wall blocks 10 may have a protrusion 30 on the side facing away from the other first wall block 10. Extending outward toward the container cavity 13 to form the protrusion 30 means that the first wall block 10 has opposing first and second sides in a first direction, with the second sides of the two first wall blocks 10 facing each other. That is, the second side of the first wall block 10 serves as the inner wall of the receiving cavity 113, and the protrusion 10 protrudes from the first side of the first wall block 10. Simultaneously, the thickness of the first wall block 10 in the first direction X remains constant, meaning that the thickness of the first wall block 10 at the protrusion 30 is the same as the thickness of the first wall block 10 elsewhere.
[0063] See Figure 1 and Figure 2 The protrusion 30 extends on the surface of the first wall block 10, and the shape of the extension is U-shaped, that is, the shape of the entire protrusion 30 on the first wall block 10 is U-shaped. The opening of the U-shape formed by the protrusion 30 faces the end of the first wall block 10 away from the bottom wall block 12. In other words, the opening of the U-shape formed by the protrusion 30 is close to the mouth of the glass container, while the bottom of the U-shape is close to the bottom wall block 12.
[0064] See Figure 9 and Figure 10 In some other embodiments, the protrusion 30 extends on the surface of the first wall block 10, and the extended protrusions 30 are connected end to end to form a closed shape. This closed shape can be circular or elliptical, or as shown in the figure. Figure 9 or Figure 10 The trapezoid shown.
[0065] Regardless of whether the protrusion 30 forms a U-shape or a closed shape, in actual use, once the glass container is in a high-temperature environment, the liquid or gas inside the glass container will expand. As analyzed above, the expansion force generated by the liquid or gas will act on the middle of the two first wall blocks 10. If the first wall block 10 is provided with a protrusion 30, the expansion force will act on the inside of the shape formed by the protrusion 30. At this time, due to the presence of the protrusion 30, the middle of the first wall block 10 will bend outward with the protrusion 30 as the fulcrum, so that the middle of the first wall block 10 can expand outward with the increase of the liquid or gas pressure in the container cavity 13. This allows the first wall block 10 to adapt to the expansion of the liquid or gas, effectively reducing the occurrence of glass container breakage.
[0066] In some embodiments of this application, the ratio of the surface area of the first wall block 10 to the surface area of the second wall block 11 is between 2 and 10. The surface area of the first wall block 10 refers to the area of the first wall block 10 located on the outer side of the container cavity 13, and the surface area of the second wall block 10 refers to the area of the second wall block 20 located on the outer side of the container cavity 13. Furthermore, by keeping the ratio of the surface area of the first wall block 10 to the surface area of the second wall block 11 between 2 and 10, the width of the first wall block 10 can be sufficiently larger than the second wall block 11, allowing the pressure generated by the liquid or gas inside the container cavity 13 to be applied to the first wall block 10 as much as possible. Simultaneously, by controlling the ratio of the width of the first wall block 10 to the width of the second wall block 11 to be not too large, it ensures that the expansion force generated by the expansion of the liquid or gas is concentrated inside the pattern formed by the protrusion 30.
[0067] Optionally, when the surfaces of the first wall block 10 and the second wall block 20 are both cubes, the ratio between a and b is between 2 and 10, so that the ratio of the surface area of the first wall block 10 to the surface area of the second wall block 11 is between 2 and 10.
[0068] In some embodiments of this application, see [reference] Figure 3 and Figure 4 The outer surface of the protrusion 30 is designed as an arc surface, that is, the surface of the protrusion 30 is a smooth curve without obvious jumps, abrupt changes or sharp corners. In this way, the middle part of the first wall block 10 changes shape more smoothly along the protrusion 30 under the expansion force of gas and liquid. It should be noted that the outer surface of the protrusion 30 refers to the surface of the protrusion 30 located on the first side of the first wall block 10, that is, the surface of the protrusion 30 away from the container cavity 13.
[0069] Furthermore, the outer surface of the first wall block 10 has a planar portion 14 connected to the protrusion 30, and the outer surface of the first wall block 10 is the surface of the first wall block 10 on the aforementioned first side. The protrusion 30 protrudes from the planar portion 14, meaning that except for the surface curvature change at the protrusion 30, the rest of the first wall block 10, i.e., the planar portion 14, is planar. Moreover, the first wall block 10 and the planar portion 14 transition smoothly, so that the smooth transition of the protrusion 30 allows the first wall block 10 to more smoothly change shape under the expansion force of gas and liquid.
[0070] Further, see Figure 2 and Figure 4 The protrusion 30 protrudes from one end of the planar portion 14 and has a first contour line 31. The first contour line 31 can be the line connecting the points on the protrusion 30 that are farthest from the planar portion 14 in the first direction X. A second contour line 32 and a third contour line 33 are formed at the points where the protrusion 30 connects to the planar portion 14, with the first contour line 31 located between the second contour line 32 and the third contour line 33. It can be understood that the second contour line 32 or the third contour line 33 is the line connecting the points on the surface of the first wall block 10 where the curvature changes abruptly at the protrusion 30. That is, when the first wall block 10 is on the planar portion 14, the curvature of each point on the planar portion 14 is 0, but when it enters the protrusion 30, the curvature changes abruptly, and the line connecting the points where the curvature changes abruptly is the second contour line 32 or the third contour line 33.
[0071] It should be noted that, because the apex of the protrusion 30 has a smooth transition, and the edge of the protrusion 30 has a smooth transition to the planar portion 14, therefore... Figure 1 and Figure 2 From a visual perspective, the second outline 32, the third outline 33, and the first outline 31 do not exist in the glass container. However, for ease of understanding, the second outline 32, the third outline 33, and the first outline 31 are represented as lines. Figure 1 and Figure 2 The marking in the middle does not mean Figure 1 and Figure 2 In the embodiment, there are bends at the second contour line 32, the third contour line 33, and the first contour line 31. Similarly, in Figure 5 or Figure 6 place, and Figure 9 or Figure 10 The protrusions 30 are marked with lines for ease of understanding.
[0072] Furthermore, the closest distance between the first contour line 31 and the second contour line 32 in the third direction Z is c, and the closest distance between the first contour line 31 and the third contour line 33 in the third direction Z is d, where c is greater than d. Thus, the area of the protrusion 30 between the first contour line 31 and the second contour line 32 is greater than the area between the first contour line 31 and the third contour line 33, thereby making the surface of the protrusion 30 between the first contour line 31 and the second contour line 32 smoother.
[0073] Thus, when the expansion force generated by the gas-liquid expansion is mainly concentrated in the middle part of the pattern formed by the protrusion 30, the expansion force will push the first wall block 10 to expand outward in the middle part of the pattern formed by the protrusion 30. Since the surface of the protrusion 30 from the first contour line 31 to the second contour line 32 is more gentle, the surface of the protrusion 30 from the first contour line 31 to the second contour line 32 is more likely to expand with the expansion of the first wall block 10, thereby reducing the occurrence of glass container breakage.
[0074] Specifically Figure 1 In the embodiment, the protrusion 30 forms a U-shape, see reference. Figure 3 and Figure 4 The lowest point of the first contour line 31 relative to the bottom wall block 12 is α; the lowest point of the second contour line 32 relative to the bottom wall block 12 in the third direction Z is β; and the lowest point of the third contour line 33 relative to the bottom wall block 12 in the third direction Z is γ. The distance between α and β in the third direction Z is c, and the distance between α and γ in the third direction Z is d. The U-shape formed by the protrusion 30 is centrally located on the first wall block 10, meaning that the centerline of the first wall block 10 passes through β, α, and γ in sequence.
[0075] When the middle and top of the first wall block 10 bend outwards with the first contour line of the protrusion 30 as the fulcrum under the expansion force of the liquid or gas expansion, this degree of expansion refers to the degree of bending of the first wall block 10 relative to the bottom wall block 12. The first wall block 10 is tilted relative to the third direction Z, so that the centerline of the first wall block 10 forms an angle @ with respect to the direction of gravity at the end away from the bottom wall block 12. When the middle and top of the first wall block 10 expand outwards with α as the center, the angle @ increases, and the distance c between α and β increases, thereby relieving the structural stress of the glass container at the first wall block 10, protecting the overall structure of the glass container, and reducing the risk of the glass container breaking.
[0076] Optionally, the ratio of c to d is between 2 and 5. When the ratio of c to d is between 2 and 5, it can ensure that there is enough area between the first contour line 31 and the second contour line 32 to smoothly guide the expansion of the middle part of the first wall block 10, and it can also avoid the distance between the first contour line 31 and the second contour line 32 being too long, resulting in a smaller degree of protrusion of the relative flat part 14 of the protrusion 30, so that the first wall block 10 cannot expand around the highest point of the protrusion 30, which would affect the effect of the glass container's thermal expansion.
[0077] Furthermore, the radius of curvature at α is r, and the distance between α and β in the first direction X is p, where p < 2r. In practical use, a larger radius of curvature r at α indicates a smoother curve at α, while a smaller radius of curvature r indicates a sharper curve at α. By controlling p < 2r, the radius of curvature r at α has sufficient length, meaning the curve at α can be smooth, allowing for a smooth transition. This mitigates the cracking caused by expansion of the first wall block 10 and reduces the likelihood of the glass container breaking.
[0078] In actual use, the bottom wall block 12 is placed in a horizontal position. When the external temperature of the glass container is between 30 and 80°C, the container initially expands under high temperature. After the contents of the container expand, and the internal gas-liquid pressure is less than 6 MPa, the original position changes compared to the static mode. The positions of the angle @ and the first contour line 31 of the protrusion 30 change, and the distance c between the first contour line 31 and the second contour line 32 changes. In this way, the elastic modulus of the glass container itself expands the volume area of the container cavity 13, satisfying the continuous expansion of the volume of the container cavity 13 and forming a linear relationship with temperature. As the temperature continues to rise, the position of the angle @ and the first contour line 31 of the protrusion 30 will also expand accordingly, relieving the stress on the outer structure of the glass container. Conversely, when the temperature drops, the angle @ and the first contour line 31 of the protrusion 30 will return to their original positions, protecting the overall structure of the glass container and reducing the chance of breakage.
[0079] Optionally, after the contents of the container expand, the angle @ will change between 1.5° and 5° to allow the glass container to generate sufficient deformation, while also avoiding excessive deformation of the glass container that could cause deformation and breakage at the connection between the first wall block 10 and the bottle mouth.
[0080] In some embodiments of this application, see [reference] Figure 3 and Figure 4When the shape formed by the protrusion 30 is U-shaped, the U-shape formed by the protrusion 30 is located in the middle of the first wall block 10 and is a symmetrical structure. The opening diameter of the U-shape formed by the protrusion 30 is e, and the maximum width of the U-shape formed by the protrusion 30 in the second direction Y is f, where e = 1 / 3f - 2 / 3f, that is, the opening of the U-shape is one-third to two-thirds of the maximum width of the U-shape. Thus, the U-shape formed by the protrusion 30 has a structure that is narrower at the top and wider at the bottom, so that the middle part of the U-shape formed by the protrusion 30 can occupy more of the surface of the first wall block 10, thereby facilitating the overall thermal deformation of the glass container.
[0081] In some embodiments of this application, the thickness of the first wall block 10 in the first direction X is g, and the thickness of the second wall block 11 in the second direction X is h, where g = 0.33mm-2mm and h = 0.33mm-2mm. That is, the thickness of the first wall block 10 and the second wall block 11 is controlled to be within a relatively thin range, so that the first wall block 10 and the second wall block 11 can have significant deformation under high temperature conditions. Combined with the U-shaped protrusion 30, high temperature resistance can be achieved under relatively thin thickness conditions.
[0082] In the embodiments of this application, since the first wall block 10 and the second wall block 11 are relatively thin, they cannot be directly formed by blow molding. Therefore, the two first wall blocks 10, the two second wall blocks 11 and the bottom wall block 12 are connected to each other by welding. That is, the glass melts at high temperature, and the melted glass can be bonded together. After cooling, the two first wall blocks 10, the two second wall blocks 11 and the bottom wall block 12 can be fixed to each other to form a complete glass container.
[0083] Furthermore, since the first wall block 10 and the second wall block 11 are to be fixed by welding, the closest distance between the outer perimeter of the pattern formed by the protrusion 30 and the edge of the first wall block 10 in the second direction Y is i, and the thickness of the second wall block 11 in the first direction X is h, where i ≥ 2h. This ensures that the protrusion 30 has sufficient distance from the side of the first wall block 10 to avoid the first wall block 10 affecting the shape of the protrusion 30 during the welding process with the second wall block 11.
[0084] The outer periphery of the shape formed by the protrusion 30 refers to the outer contour line of the U-shaped or closed shape formed by the protrusion 30. Specifically, when the protrusion 30 is U-shaped, the outer periphery of the shape formed by the protrusion 30 refers to the aforementioned third contour line 33.
[0085] Furthermore, the closest distance between the outer perimeter of the shape formed by the protrusion 30 and the edge of the bottom wall block 12 in the third direction Z is j, and the thickness of the bottom wall block 12 in the third direction is k, where j ≥ 2k. This ensures that the protrusion 30 has sufficient distance from the bottom of the first wall block 10 to avoid affecting the shape of the protrusion 30 during the welding process between the first wall block 10 and the bottom wall block 12.
[0086] In some other embodiments, the protrusion 30 may include multiple protrusions, see below. Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the protrusion 30 includes two protrusions 30, each protrusion 30 extending in a U-shape. One protrusion 30 is located inside the U-shape formed by the other protrusion 30. That is, the width of the U-shape formed by one protrusion 30 in the second direction Y is smaller, and the width of the U-shape formed by the other protrusion 30 in the second direction is larger, so that the smaller U-shape can be set inside the larger U-shape.
[0087] Furthermore, each protrusion 30 has two ends spaced apart along the second direction Y at its U-shaped opening, and the end of each protrusion 30 is connected to the end of the other protrusion 30, so that the two protrusions 30 can form a whole. In actual use, each protrusion 30 expands with the expansion of the first wall block 10, so that the first wall block 10 can adapt to the expansion of liquid or gas, effectively reducing the occurrence of glass container breakage.
[0088] Specifically, for ease of description, the protrusion 30 with a smaller U-shape size is defined as the first protrusion 40, and the protrusion 30 with a larger U-shape size is defined as the second protrusion 41. The first protrusion 40 is located inside the U-shape formed by the second protrusion 41.
[0089] When the middle part of the first wall block 10 is subjected to the expansion force of gas and liquid, the middle part of the first wall block 10 will first bend outward around the first protrusion 40 as the fulcrum. If the bending degree of the middle part of the first wall block 10 is large, it will continue to drive the middle part of the first wall block 10 and the first protrusion 40 to bend outward together around the second protrusion 41 as the fulcrum. In this way, through the cooperation of the two protrusions 30, the first wall block 10 can undergo multiple adaptive expansions, which effectively improves the overall structural strength of the glass container and reduces the phenomenon of glass container breakage.
[0090] Furthermore, since the portion between the first protrusion 40 and the second protrusion 41 is still a planar portion 14, its resistance to expansion forces is relatively poor. Therefore, the first wall block 10 also has a reinforcing portion 42 protruding outwards towards the container cavity 13. The reinforcing portion 42 is located between the two protrusions 30. By providing the reinforcing portion 42 between the first protrusion 40 and the second protrusion 41, the structural strength of the first wall block 10 is further improved, reducing the likelihood of glass container breakage. Optionally, the reinforcing portion 42, the first protrusion 40, and the second protrusion 41 all protrude at the same height relative to the planar portion 14.
[0091] In some other embodiments, see Figure 9 , Figure 10 , Figure 11 and Figure 12 In this embodiment, the protrusions 30 include multiple protrusions 30, each protrusion 30 forming a closed shape, and the closed shapes formed by all the protrusions 30 are sequentially nested from the inside out. Specifically... Figure 9 In one embodiment, the protrusion 30 includes three, and the closed shape formed by each protrusion 30 is a trapezoid. The area of each trapezoid increases sequentially, thereby realizing the three trapezoids being nested from the inside out.
[0092] In actual use, the middle part of the first wall block 10 first bends outward around the innermost protrusion as a fulcrum. If the bending degree of the middle part of the first wall block 10 is large, it will further bend outward around the middle protrusion as a fulcrum until it bends outward around the outermost protrusion as a fulcrum. In this way, the first wall block 10 can undergo multiple adaptive expansions, effectively improving the overall structural strength of the glass container and reducing the phenomenon of glass container breakage. Furthermore, the connecting surfaces between the various protrusions 30 are arc surfaces, so that the various protrusions 30 can smoothly transition between each other, thereby making the process of each protrusion 30 expanding with the first wall block 30 smoother.
[0093] Among them, the structure of traditional glass containers without protrusions is defined as A1. Figures 9-12 The central protrusion 30 includes multiple protrusions, and each protrusion 30 forms a trapezoidal structure defined as B. Based on the different heights of the protrusions 30 relative to the planar portion 14, they are defined as B1 and B2. Figures 5-8 The central protrusion 30 includes two protrusions, both of which are U-shaped structures defined as C, and are designated as C1 and C2 based on their different heights. Figures 1-4 The structure is defined as D1. The following are deformation data obtained by applying a certain air pressure to the glass containers in each structure. For ease of comparison, the wall thickness of the glass containers in each structure is 1.0 mm. The data are as follows: Figure 13As shown, stress refers to the stress generated inside the glass container structure, and displacement is the displacement distance of the first wall block 10 relative to its initial state in the first direction X.
[0094] For the A1 structure, which is a traditional glass container without protrusions, the stress generated after applying air pressure is 141.1 MPa and the displacement is 0.85 mm.
[0095] For the structure B1, which is a structure in which each protrusion is arranged in a trapezoidal shape and the protrusion height is 0.5mm, after applying air pressure, the stress generated by the structure B1 is 129.1MPa and the displacement is 0.86mm.
[0096] For the structure B2, which is a structure in which each protrusion is arranged in a trapezoidal shape with a height of 1.0 mm, the stress generated after applying air pressure to the B2 structure is 124.2 MPa and the displacement is 0.82 mm.
[0097] For the structure of C1, which includes two protrusions 30, both of which are U-shaped and have a height of 1.0 mm, the stress generated after applying air pressure to the C1 structure is 131.7 MPa and the displacement is 0.85 mm.
[0098] For the structure of C2, which includes two protrusions 30, both of which are U-shaped and have a height of 3.0 mm, the stress generated after applying air pressure to the C2 structure is 113.5.1 MPa and the displacement is 0.78 mm.
[0099] For the structure of D1, which includes one protrusion 30, and all of the protrusions 30 are U-shaped and have a height of 4.0 mm, after applying air pressure, the stress generated by the structure of D1 is 88.9 MPa and the displacement is 0.73 mm.
[0100] For ease of comparison, the experimental data above are presented in a table as follows:
[0101]
[0102] The experimental data above shows that, compared to traditional textureless structures, the protrusions 30 effectively reduce the stress inside the glass container and the displacement of the first wall block 10, thereby effectively reducing the risk of the glass container breaking. It should be noted that in actual use, when the wall thickness of the glass container (i.e., the wall thickness of the first wall block 10 and the second wall block 11) is between 0.5mm and 1.5mm, the glass container can maintain sufficient space to adapt to changes in internal pressure through expansion.
[0103] Please refer to Figure 4 An embodiment of this application also provides a method for processing a glass container, used to process a glass container as described in any of the above embodiments, the processing method comprising the following steps:
[0104] S100: Provides two first wall blocks 10, two second wall blocks 11, and one bottom wall block 12.
[0105] Specifically, the first wall block 10, the second wall block 11, and the bottom wall block 12 can be pre-processed, that is, the various walls used to assemble the glass container are prepared in advance.
[0106] S200: Two first wall blocks 10, two second wall blocks 11, and one bottom wall block 12 are placed in the welding cavity of the welding mold, wherein the inner contour shape of the welding cavity matches the outer contour shape of the glass container, so that the two first wall blocks 10, two second wall blocks 11, and one bottom wall block 12 are respectively attached to the inner surface of the welding cavity, thereby splicing them together to form an initial container.
[0107] It is understandable that the outer contour shape of the glass container is the contour shape of the outer surface formed by the two first wall blocks 10, the two second wall blocks 11, and the bottom wall block 12, and the inner contour shape of the welding cavity matches the outer contour shape of the glass container.
[0108] S300: The welding mold containing the initial container is placed in a high-temperature device, and high-pressure gas is introduced into the initial container so that the initial container is pressed tightly against the inner surface of the welding cavity under the action of the high-pressure gas, and the two first wall blocks 10, two second wall blocks 11 and a bottom wall block 12 are welded together under the heating action of the high-temperature device.
[0109] Specifically, the pressure value of the high-pressure gas can be set according to the requirements of the actual processing conditions. This embodiment does not specifically limit the pressure range of the high-pressure gas, as long as the gas pressure is sufficient to ensure that each wall of the initial container is tightly attached to the inner surface of the welding cavity. This embodiment does not specifically limit the heating temperature of the high-temperature equipment, as long as it allows the two first wall blocks 10, the two second wall blocks 11, and the bottom wall block 12 to weld together. When introducing high-pressure gas into the initial container, it can be introduced through the opening of the initial container.
[0110] During the welding process of the walls of the initial container under the heating action of the high-temperature equipment, the walls of the initial container can be tightly attached to the inner surface of the welding cavity by the action of high-pressure gas. Thus, the inner surface of the welding cavity can shape the outer surface of the walls of the initial container, ensuring that the shape and dimensional accuracy of the walls of the initial container still conform to the shape and dimensional accuracy of the glass container after welding.
[0111] S400: Cools the welding mold and its internal initial container to allow the initial container to set after welding, forming a glass container.
[0112] After welding is completed, the walls of the initial container remain unformed under high temperature. In this step, the initial container inside the welding mold is cooled down and formed, resulting in a stable glass container.
[0113] Specifically, cooling can be achieved by gradually reducing the heating temperature of the high-temperature equipment. During the initial cooling stage, the initial container is not yet set; therefore, high-pressure gas must continue to be introduced into the initial container to ensure that all walls of the initial container are tightly attached to the inner surface of the welding cavity. Once the initial container has set, the introduction of high-pressure gas can be stopped.
[0114] S500: Open the welding mold to remove the glass container.
[0115] The shaped glass container can be easily removed by opening the welding mold.
[0116] In one embodiment, the welding mold is provided with an air extraction port, which communicates with the welding cavity. During the actual welding process, a small amount of air may exist within the welding cavity, resulting in a small air gap between the outer surface of the initial container and the inner surface of the welding cavity, affecting the tightness of the fit between the initial container and the welding cavity. Therefore, in this embodiment, the glass container processing method further includes performing step S600 before step S400. S600 includes: extracting the air between the outer surface of the initial container and the inner surface of the welding cavity through the air extraction port. This facilitates a tighter fit between the outer surface of the initial container and the inner surface of the welding cavity, thereby improving the dimensional accuracy of the glass container.
[0117] Specifically, in step S300, after high-pressure gas is introduced into the initial container for a certain period of time (e.g., after 30 to 100 seconds at saturation), step S600 can be executed.
[0118] The aforementioned glass containers have at least the following advantages:
[0119] In practical use, when a glass container is exposed to a high-temperature environment, the liquid or gas inside the container will expand. As analyzed above, the expansion force generated by the liquid or gas will act on the middle of the two first wall blocks 10. If the first wall block 10 has a protrusion 30, the expansion force will act on the interior of the pattern formed by the protrusion 30. At this time, due to the presence of the protrusion 30, the middle of the first wall block 10 will bend outward with the protrusion 30 as the fulcrum, so that the middle of the first wall block 10 can expand outward with the increase of the liquid or gas pressure in the container cavity 13. This allows the first wall block 10 to adapt to the expansion of the liquid or gas, effectively reducing the occurrence of glass container breakage.
[0120] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0121] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
