Description

Technical Field

[0001] The invention relates to the technical field of beverage cups, and in particular to a beverage cup which utilizes composite materials to achieve a bottom heat conduction effect and a manufacturing process thereof. Background Art

[0002] Disposable infusion cups are common disposable items used to hold various beverages in daily life and are widely used in the beverage industry. In the beverage industry, disposable beverage cups are mainly divided into paper cups and plastic cups. The inner layer of the paper cup is made of food-grade membrane waterproof material, and the outer layer is made of paper material. The paper material has a certain heat insulation effect, which makes this type of paper cup widely used in hot drinks such as coffee; plastic cups are made of food-grade plastic through one-piece molds, generally made of food-grade PP material. This type of material has low production cost and is widely used in cold or warm drinks such as fruit tea and milk tea.

[0003] However, with the more intelligent development of the beverage industry, many users can place orders online anytime and anywhere through the corresponding APP or mini-programs when the business is open. This phenomenon will appear more and more often when drinks are prepared and waiting for customers to pick them up. Some hot or warm drinks will cause large temperature changes after waiting for too long, affecting the taste, especially in cold weather. This phenomenon will be common. In order to solve this problem, some beverage shops will use microwave ovens for heating, and some stores will make a heating film, and place the prepared hot drinks directly on the heating film for insulation, and then keep them warm through the heating film. This method of insulation through the heating film will enable employees to avoid additional heating operations, thereby greatly improving work efficiency; however, since the beverage cup itself is not set in this regard, the insulation effect of the heating film on the lead cup is not obvious, and thus it cannot be widely popularized. In this regard, it is necessary to propose a beverage cup that can be used on a heating film for efficient insulation. Summary of the invention

[0012] A process for manufacturing a beverage cup, for manufacturing the beverage cup using the composite material to achieve the bottom heat conduction effect, comprises the following steps: Step 1, raw material preparation, select food-grade silicone that meets food contact safety standards as the raw material for making the soft temperature-resistant body, and select food-grade safe PP or PLA as the raw material for making the hard support body and the hard transition body; Step 2, mixing the silicone, mixing the prepared silicone raw materials with the vulcanizing agent in a special mixing equipment to evenly mix the silicone and the vulcanizing agent to ensure that the performance of the silicone products is uniform during subsequent processing and use; Step 3, forming a soft heat-resistant body, making a corresponding mold according to the design shape and size of the soft heat-resistant body, putting the mixed silicone raw material into the mold according to a certain amount, and then putting the mold into a pressing device, vulcanizing and molding at 120°C-140°C, and forming a soft heat-resistant body after vulcanization molding; Step 4, forming a rigid support body and a rigid transition body, making corresponding molds according to the designed shapes and sizes of the rigid support body and the rigid transition body, heating the PP or PLA raw material to a molten state and injecting it into the mold, wherein the temperature of the PP raw material in the molten state is controlled at 200° C.-230° C., and the temperature of the PLA raw material in the molten state is controlled at 180° C.-230° C., cooling and solidifying after injection, and demolding after forming to obtain a rigid support body and a rigid transition body; Step 5, bonding a hard transition body to the outside of the soft heat-resistant body, setting a corresponding conveying jig according to the structure of the soft heat-resistant body, and putting the formed soft heat-resistant body on the conveying jig upside down, and transferring the conveying jig to a pre-set coating machine through a conveyor line to apply heat-resistant glue to the upper part of the soft heat-resistant body, and after coating the heat-resistant glue, transferring it to the mold of the formed hard transition body, and putting the formed hard transition body on the outside of the soft heat-resistant body coated with glue by a robot or manually, and then transferring it to a dryer for drying and baking the glue, so that the soft heat-resistant body and the hard transition body are bonded together; Step 6, assembling the cup body, forming a wavy fixed structure on a section of the hard support body and the hard transition body through a mold, bonding the soft heat-resistant body and the hard support body, and then putting the hard support body on the initial finished product, so that the hard support body and the soft heat-resistant body are clamped and fixed through the wavy fixed structure to form a cup body.

[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-5In an embodiment of the present invention, a beverage cup that uses composite materials to achieve a bottom heat conduction effect is proposed. A cup body 10 is provided. The cup body 10 uses a composite layer structure, so that a soft, heat-resistant layer that can be tightly attached to a heating film can be formed at the bottom of the cup body 10, so that the heat generated by the heating film can be efficiently conducted to the beverage in the cup body 10, thereby providing the beverage with a certain temperature to achieve a warming effect. Specifically, the cup body 10 comprises a soft heat-resistant body 11, a hard support body 12 and a hard transition body 13. The soft heat-resistant body 11 is a cup-shaped container structure with an opening; the hard transition body 13 and the hard support body 12 are both sleeve-shaped structures, the hard transition body 13 is bonded to the outside of the soft heat-resistant body 11, and the upper end of the hard transition body 13 is aligned with the opening of the soft heat-resistant body 11, and the lower end of the hard transition body 13 is higher than the soft heat-resistant body 11, and the hard support body 12 is provided with a plurality of layers. The support body 12 is sleeved on the outside of the hard transition body 13, and a fixed structure is arranged between the hard support body 12 and the hard transition body 13. The hard transition body 13 and the hard support body 12 are fixedly matched through the fixed structure, and the lower end of the hard support body 12 is used to support the cup body 10 to maintain a vertical state; the hard support body 12 is located at the outermost layer of the cup body 10, and plays a role of holding and supporting. It can be made of paper material or plastic material. The technical solution preferably adopts plastic material to make the hard support body 12, especially PP or PLA material; PP material does not react to most chemicals, is non-toxic and harmless, can contact the hard support body 12 during drinking, and PP products can be used in a high temperature environment below 100 degrees for a long time, and will not be obviously deformed when the temperature reaches about 150 degrees in a short time. Therefore, it can hold hot coffee, milk tea and other drinks at higher temperatures, without worrying about the cup being deformed or damaged due to heat during normal use. In addition, PP materials can be recycled and reused, which helps reduce resource waste and environmental pollution, and is in line with the concept of sustainable development. PLA is a new type of biodegradable material, made from starch raw materials from renewable plant resources. In the natural environment, PLA cups can be decomposed by microorganisms and eventually generate carbon dioxide and water, which has less pollution to the environment, helps reduce white pollution, and meets environmental protection requirements. PLA also has good heat resistance and impact resistance, can withstand certain high temperatures and various use environments, and ensure safe and stable use. Its strength and toughness can also meet the use requirements of beverage cups; in addition, PLA materials are easy to form and process, the production process is simple, and it is compatible with traditional plastic processing equipment, which reduces production costs. When PLA material is selected, since PLA material has a low high temperature resistance, a circle of high temperature resistant rubber pad can be attached to the lower end of the hard support body 12, and the high temperature resistant rubber pad is made of silicone material; the high temperature resistant rubber pad can ensure that when the cup body 10 is placed on the heating film, there is a certain isolation between the heating film and the hard support body 12, thereby protecting the cup body 10. In addition, it can also enhance the strength of the bottom of the cup body 10, making the cup body 10 more firm and stable when placed so that it will not easily tip over.The soft heat-resistant body 11 is made of food-grade materials, and it is necessary to ensure that the material can achieve the effect of heat resistance. It can be made of food-grade silicone material, or it can be made of thermoplastic polyester elastomer material, food-grade polycarbonate material, food-grade polyacrylate material, food-grade polyphenylene sulfide material or food-grade isotactic polystyrene material; due to the high transparency and good stability of silicone, its high temperature resistance is excellent, it can be used for a long time in the temperature range of -40°C to 250°C, and can even withstand higher temperatures in a short time, and it has the advantages of being soft, elastic, resistant to kinking, deformation, cracking, and long service life. It also has good cold resistance. In addition, it is non-toxic, odorless, does not turn yellow, does not frost, does not whiten, does not fade, and has no scale or odor even when placed in water for a long time; therefore, the technical scheme preferably selects food-grade silicone to make the soft heat-resistant body 11.

[0021] On the basis of the above technical scheme, the bottom surface of the soft heat-resistant body 11 is an arc-shaped structure lower than the lower end of the hard support body 12, so that when the cup body 10 is placed, the bottom surface of the soft heat-resistant body 11 is subjected to force and flexibly deformed to be flush with the lower end of the hard support body 12; the setting of this structure enables the bottom surface of the soft heat-resistant body 11 to be in close contact with the heating film after the cup body 10 filled with a beverage is placed on the heating film, and in terms of size setting, it is set as much as possible so that the arc-shaped structure at the lower end of the soft heat-resistant body 11 can be flush with and just abut against the lower end of the hard support body 12 during the placement of the cup body 10, or the arc-shaped structure at the lower end of the soft heat-resistant body 11 can be flush with the lower end of the hard support body 12 during the placement of the cup body 10, and there is only a gap between the hard support body 12; thereby, it can ensure that the overall capacity is almost corresponding to the overall size of the cup body 10, and the soft heat-resistant body 11 can be fully in contact with the heating film to the greatest extent.

[0022] The cup body 10 is formed by adopting a three-layer structure with a hard structure on the outside and a soft structure on the bottom, so that the cup body 10 has both the structural characteristics of a traditional disposable beverage cup and the function of being able to be in close contact with a placement surface. The interior of the cup body 10 is made of a high temperature resistant material and can hold hot drinks and warm drinks. When a customer fails to take a drink in time, the drink can be placed on the heating film to most effectively keep the drink warm. By setting the hard transition layer, a good transition effect can be achieved, so that the cup body 10 can be formed with only a hard structure on the upper part, and the lower part can have both a hard structure and a soft structure, so as to achieve stable placement of the cup body 10 and close contact with the heating film. The setting of the hard transition layer can also simplify the processing difficulty, and can accurately match the hard support body 12 with the soft heat-resistant body 11, thereby improving the product yield; for example, after removing the hard transition body 13, when bonding the hard support body 12 and the soft heat-resistant body 11, it is inevitable that it will be bonded to the lower half of the hard support body 12 and the soft heat-resistant body 11, resulting in the soft The flexibility of the heat-resistant body 11 is reduced, and even the bottom of the soft heat-resistant body 11 may be concave into the lower end of the hard support body 12 after being manufactured, resulting in a reduction in the heat conduction effect of the bottom. The setting of the hard transition body 13 enables the cup body 10 to bond the hard transition body 13 and the soft heat-resistant body 11 through a simple bonding process when the hard support body 12 is not set; and then the hard transition body 13 and the hard support body 12 are fixedly matched by an ingenious fixing structure. This design reasonably solves the problem of bonding only the upper half of the hard support body 12 and the soft heat-resistant body 11, thereby reducing the difficulty of the production and processing process; In addition, the use of the hard transition body 13 can increase the strength of the upper half of the cup body 10, so that it can be firmly held, and after being covered with the cup lid 20, it can have sufficient strength to maintain the sealing of the cover. The hard support body 12 does not need to consider these two points, so the thickness can be made smaller; for example, in order to ensure the firmness of holding and the tightness of covering with the cup lid 20, the hard support body 12 needs to be made to be more than 0.3mm, and the setting of the hard transition body 13, that is, the sum of the thickness of the hard transition body 13 and the hard support body 12 needs to be more than 0.3mm. Even if the hard support body 12 is too thin, the cup body 10 can maintain a stable placement shape when placed due to the force of the beverage itself on the cup body 10.

[0023] Finally, the structural setting of the cup body 10, in addition to improving the heat conduction effect at the bottom, can also make the lower half of the cup body 10 have a certain flexibility. When using a straw to drink beverages with granular ingredients such as pearls, the pearls and other small ingredients can be put into the straw by manually moving the lower end of the cup body 10, thereby solving the problem of discarding and wasting beverages with pearls and other small ingredients because the small ingredients cannot be sucked.

[0024] See also Figure 1-5On the basis of the above technical solution, it is further proposed that the fixed structure includes a first wave segment 14 arranged on the hard transition body 13 and a second wave segment 15 arranged on the hard support body 12, and the hard transition body 13 and the hard support body 12 are tightly matched, so that the first wave segment 14 and the second wave segment 15 are snap-fitted to achieve fixed matching of the hard transition body 13 and the hard support body 12; in the above technical solution, based on the setting of the fixed structure, the technical solution sets the fixed structure from the perspective of structural flexibility and recycling convenience. In order to achieve the purpose of snap-fitting with a simple wavy structure, the hard support body 12 and the hard transition body 13 can be separated, which can not only improve the flexibility of the cup body 10, but also facilitate subsequent recycling. In terms of design, the second wave section 15 can be only arranged on the inner side of the hard support body 12, that is, the outer wall of the cup body 10 is a flat structure. This method is conducive to the fact that when multiple cup bodies 10 are put together, the wavy structures between adjacent cup bodies 10 will not snap-fit ​​with each other, resulting in the situation where only the hard support body 12 is taken out when the cup body 10 is taken out. In order to ensure that the cup body 10 can be securely covered with the cup cover 20, the cup mouth adopts the structure of the traditional disposable beverage cup mouth, and the upper ends of the soft temperature-resistant body 11, the hard transition body 13 and the hard support body 12 are bent outward to form a fixing flange 16. This structure can be consistent with the traditional cup cover 20 and cup body 10 covering structure, that is, the beverage cup also includes a cup cover 20 covering the cup body 10, and the edge of the cover has a clamping ring 21 that cooperates with the fixing flange 16, so that the cup cover 20 is fixedly covered on the cup body 10 through the clamping cooperation between the clamping ring 21 and the fixing flange 16; and the hard transition body 13 and the hard support body 12 are tightly fitted through the fixing flange 16, so that the fitting degree between the hard support body 12 and the hard transition body 13 is higher.

[0025] See also Figure 1-6 In order to explain the technical solution of the present invention in more detail, the present invention proposes a manufacturing process of a beverage cup, which is used to manufacture the beverage cup using the composite material to achieve the bottom heat conduction effect as described above, comprising the following steps: Step 1, raw material preparation, selecting food-grade silicone that meets food contact safety standards as the raw material for making the soft temperature-resistant body 11, and selecting food-grade safety PP or PLA as the raw material for making the hard support body 12 and the hard transition body 13; Step 2, mixing the silicone, mixing the prepared silicone raw materials with the vulcanizing agent in a special mixing equipment to evenly mix the silicone and the vulcanizing agent to ensure that the performance of the silicone products is uniform during subsequent processing and use; Step 3, forming the soft heat-resistant body 11, making a corresponding mold according to the design shape and size of the soft heat-resistant body 11, putting the mixed silicone raw material into the mold according to a certain amount, and then putting the mold into a pressing device, vulcanizing and molding at 120° C.-140° C., and forming the soft heat-resistant body 11 after vulcanization molding; Step 4, forming a rigid support body 12 and a rigid transition body 13, making corresponding molds according to the designed shapes and sizes of the rigid support body 12 and the rigid transition body 13, heating the PP or PLA raw material to a molten state and injecting it into the mold, wherein the temperature of the PP raw material in the molten state is controlled at 200° C.-230° C., and the temperature of the PLA raw material in the molten state is controlled at 180° C.-230° C., cooling and solidifying after injection, and demolding after forming to obtain the rigid support body 12 and the rigid transition body 13; Step 5, bonding the hard transition body 13 to the outside of the soft heat-resistant body 11, setting a corresponding conveying jig according to the structure of the soft heat-resistant body 11, and invertingly sleeve the formed soft heat-resistant body 11 on the conveying jig, and transferring the conveying jig to a pre-set coating machine through a conveyor line to apply heat-resistant glue to the upper half of the soft heat-resistant body 11, and after coating the heat-resistant glue, transferring it to the mold for forming the hard transition body 13, sleeve the formed hard transition body 13 on the outside of the soft heat-resistant body 11 coated with glue by a robot or manually, and then transferring it to a dryer for drying and baking the glue, so that the soft heat-resistant body 11 and the hard transition body 13 are bonded together; Step 6, assembling the cup body 10, forming a wavy fixed structure on a section of the hard support body 12 and the hard transition body 13 through a mold, bonding the soft heat-resistant body 11 and the hard support body 12 together, and then sleeve the hard support body 12 on the initial finished product, so that the hard support body 12 and the soft heat-resistant body 11 are clamped and fixed through the wavy fixed structure to form the cup body 10.

[0026] That is, in the process of making the cup body 10 of the present invention, traditional mold forming is adopted to complete the bonding and assembly method. The process is simple. Even if it is made into a three-layer structure of a soft heat-resistant body 11, a hard support body 12 and a hard transition body 13, it can be completed under a relatively low-cost process, so that the production cost of the cup body 10 is reasonable. In addition, during the production process, the hard transition body 13 and the soft heat-resistant body 11 can be fully automated and integrated through specific conveying jigs, conveying lines, coating machines and drying machines, effectively reducing labor costs. In addition, if the hard support body 12 is made of PLA material, a circle of high-temperature resistant rubber pads with a thickness of 0.8mm-1.3mm is coated on the lower end of the hard support body 12, so that the lower end of the hard support body 12 can be effectively isolated from the heating film.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
