Description

Technical Field

[0001] The present invention relates to the technical field of beverage cups, in particular to a beverage cup that 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 mold molding, generally made of food-grade PP material. This type of material has low production cost and is widely used in cold drinks 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 corresponding APPs 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. To this end, it is necessary to propose a beverage cup that can be used on a heating film for efficient insulation. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0005] A beverage cup that utilizes composite materials to achieve a bottom heat conduction effect comprises a cup body, wherein the cup body comprises a soft heat-resistant body, a hard support body, and a hard transition body. The soft heat-resistant body is a cup-shaped container structure with an opening. Both the hard transition body and the hard support body are sleeve-shaped structures. The hard transition body is bonded to the outside of the soft heat-resistant body, and the upper end of the hard transition body is aligned with the opening of the soft heat-resistant body. The lower end of the hard transition body is higher than the soft heat-resistant body. The hard support body is sleeved on the outside of the hard transition body. A fixing structure is provided between the hard support body and the hard transition body. The hard transition body and the hard support body are fixedly matched by the fixing structure. The lower end of the hard support body is used to support the cup body to maintain an upright state.

[0006] Among them, the bottom surface of the soft heat-resistant body is an arc-shaped structure lower than the lower end of the hard support body, so that when the cup body is placed, the bottom surface of the soft heat-resistant body is subjected to force and flexibly deformed to be flush with the lower end of the hard support body.

[0007] Preferably, the fixed structure includes a first wave segment arranged on the hard transition body and a second wave segment arranged on the hard support body. The hard transition body and the hard support body are tightly fitted together, so that the first wave segment and the second wave segment are snap-fitted to achieve fixed fit between the hard transition body and the hard support body.

[0008] Preferably, the second wave segment is arranged on the inner side of the rigid support body.

[0009] Preferably, the upper ends of the soft temperature-resistant body, the hard transition body and the hard support body are all bent outward to form a fixing flange, and the hard transition body and the hard support body are tightly fitted through the fixing flange.

[0010] Preferably, the beverage cup further comprises a cup cover covering the cup body, wherein the edge of the cover has a clamping ring matched with the fixed flange, so that the cup cover is fixedly covered on the cup body by the clamping ring and the fixed flange.

[0011] Preferably, the soft temperature-resistant body is made of silicone material, and the hard support body and the hard transition body are made of PP material.

[0012] Preferably, the soft temperature-resistant body is made of silicone material, the hard support body and the hard transition body are made of PLA material, and a circle of high-temperature resistant rubber pad is attached to the lower end of the hard support body, and the high-temperature resistant rubber pad is made of silicone material.

[0013] A process for manufacturing a beverage cup, for manufacturing the beverage cup described above that utilizes composite materials to achieve bottom heat conduction effect, comprises the following steps:

[0014] Step 1: Prepare the raw materials. Select food-grade silicone that meets food contact safety standards as the raw material for the soft heat-resistant body, and select food-grade safe PP or PLA as the raw material for the hard support body and hard transition body.

[0015] Step 2: Silicone mixing: Mix 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 product is uniform during subsequent processing and use;

[0016] Step 3: Forming the soft heat-resistant body. According to the designed shape and size of the soft heat-resistant body, a corresponding mold is made, and a certain amount of the mixed silicone raw material is put into the mold. The mold is then placed in a pressing device and vulcanized at 120°C-140°C to form the soft heat-resistant body.

[0017] Step 4: forming a rigid support body and a rigid transition body. According to the designed shapes and sizes of the rigid support body and the rigid transition body, corresponding molds are made, and the PP or PLA raw material is heated to a molten state and then injected into the mold. The temperature of the PP raw material in the molten state is controlled at 200° C. to 230° C., and the temperature of the PLA raw material in the molten state is controlled at 180° C. to 230° C. After injection, the raw material is cooled and solidified. After forming, the mold is removed to obtain the rigid support body and the rigid transition body.

[0018] Step 5, bonding the 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 upside down on the conveying jig. The conveying jig is transferred 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. After the heat-resistant glue is applied, it is transferred to the mold for forming the hard transition body. The formed hard transition body is put on the outside of the soft heat-resistant body coated with glue by a robot or manually, and then transferred to a dryer for drying and baking the glue, so that the soft heat-resistant body and the hard transition body are bonded together;

[0019] 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 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.

[0020] Preferably, if the rigid support body is made of PLA material, a circle of high temperature resistant rubber pad with a thickness of 0.8 mm to 1.3 mm is coated on the lower end of the rigid support body.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The bottom surface of the soft heat-resistant body is an arc-shaped structure that is lower than the lower end of the hard support body. When the cup is placed, the bottom surface of the soft heat-resistant body is subjected to force and flexibly deforms until it is flush with the lower end of the hard support body. This structure ensures that after the cup containing the beverage is placed on the heating film, the bottom surface of the soft heat-resistant body can be in close contact with the heating film, thereby improving the heat conduction effect of the bottom of the cup body and enabling the heating film to efficiently transfer heat to the beverage in the cup body.

[0023] The three-layer structure forms a cup body with a hard outer structure and a soft bottom structure. This cup body has the structural characteristics of a traditional disposable beverage cup and the ability to maintain close contact with the surface it is placed on. The interior of the cup body is made of high-temperature resistant material and can hold both hot and warm drinks. If the customer does not take the drink in time, the cup can be placed on the heating film to effectively keep the drink warm.

[0024] The provision of the hard transition layer can play a good transition role, so that the upper part of the cup body can have only a hard structure, while the lower part can have both a hard structure and a soft structure, thereby achieving stable placement of the cup body and close contact with the heating film; the provision of the hard transition layer can simplify the processing difficulty, can accurately match the hard support body with the soft temperature-resistant body, and improve the product yield;

[0025] The use of a hard transition body can increase the strength of the upper half of the cup body, so that it can be firmly held, and it can have sufficient strength to maintain the sealing of the cover after being closed with the cup lid. The hard support body does not need to consider these two points, so the thickness can be made smaller, which can save materials to a certain extent and reduce the material cost of the cup body.

[0026] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0037] 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, temperature-resistant layer that can be in close contact with the 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 includes a soft, temperature-resistant body 11, a hard support body 12 and a hard transition body 13. The soft, temperature-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, temperature-resistant body 11, and the upper end of the hard transition body 13 is aligned with the opening of the soft, temperature-resistant body 11, and the lower end of the hard transition body 13 is higher than the soft, temperature-resistant body 11. The support body 12 is sleeved on the outside of the hard transition body 13, and a fixed structure is provided 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 an upright state; the hard support body 12 is located at the outermost layer of the cup body 10, and plays the role of holding and supporting. It can be made of paper material or plastic material. The present technical solution preferably adopts plastic material for the hard support body 12, especially PP or PLA material; PP material does not react to most chemicals, is non-toxic and harmless, can come into contact with the hard support body 12 during drinking, and PP products can be used for a long time in a high temperature environment below 100 degrees, and will not be obviously deformed when the temperature reaches about 150 degrees in a short time. Therefore, it can hold hot beverages like hot coffee and milk tea without worrying about deformation or damage from heat during normal use. Furthermore, PP is recyclable, helping to reduce resource waste and environmental pollution, aligning with the concept of sustainable development. PLA is a new biodegradable material made from starch derived from renewable plant resources. In the natural environment, PLA cups are decomposed by microorganisms, ultimately producing carbon dioxide and water, with minimal environmental pollution, helping to reduce white pollution and complying with environmental protection requirements. PLA also has excellent heat and impact resistance, withstanding certain high temperatures and a variety of operating environments, ensuring safe and stable use. Its strength and toughness also meet the requirements for beverage cups. Furthermore, PLA is easy to mold and process, with a simple production process compatible with traditional plastic processing equipment, reducing production costs. When PLA material is selected, since PLA material has a low resistance to high temperatures, 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 strengthen 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, and 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. It has the advantages of being soft, elastic, resistant to kinking, deformation, cracking, and having a 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 present technical solution preferably selects food-grade silicone to make the soft heat-resistant body 11.

[0038] 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 cup body 10 filled with a beverage to be placed on the heating film, and the bottom surface of the soft heat-resistant body 11 can be in close contact with the heating film. 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 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 it and 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 can also make the soft heat-resistant body 11 fully contact with the heating film to the greatest extent.

[0039] The cup body 10 is formed by adopting a three-layer structure with a hard outer structure and a soft bottom structure. This allows the cup body 10 to have the structural characteristics of a traditional disposable beverage cup while also being able to maintain close contact with the surface on which it is placed. The interior of the cup body 10 is made of a high-temperature resistant material and can hold both hot and warm drinks. When a customer does not take their drink in time, they can place it on the heating film to effectively keep the drink warm.

[0040] 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 the hard support body 12 and the lower half of the soft heat-resistant body 11 will be bonded, resulting in the soft The flexibility of the heat-resistant body 11 is reduced, and the bottom of the soft heat-resistant body 11 may even be concave into the lower end of the hard support body 12 after it is manufactured, resulting in a reduction in the heat conduction effect of the bottom. The provision of the hard transition body 13 enables the cup body 10 to be bonded to 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 provided; 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.

[0041] 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 grasped, 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 it can be made smaller in thickness; for example, in order to ensure the firmness of the grip and the tightness of the cover with the cup lid 20, the hard support body 12 needs to be made to be more than 0.3 mm, 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 0.3 mm. 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.

[0042] 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 small ingredients such as pearls, the pearls and other small ingredients can be manually moved to allow the pearls and other small ingredients to be placed into the straw, solving the problem of drinking beverages with pearls and other small ingredients being discarded and wasted because the small ingredients cannot be sucked.

[0043] 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 provided on the rigid transition body 13 and a second wave segment 15 provided on the rigid support body 12, and the rigid transition body 13 and the rigid 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 fit between the rigid transition body 13 and the rigid support body 12; in the above technical solution, based on the setting of the fixed structure, the present technical solution sets the fixed structure from the perspectives 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 later recycling. In terms of design, the second wavy section 15 can be set only 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 firmly covered with the cup lid 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 fixed flange 16. This structure is consistent with the traditional cup lid 20 and cup body 10 covering structure, that is, the beverage cup also includes a cup lid 20 covering the cup body 10, and the edge of the cover has a clamping ring 21 that cooperates with the fixed flange 16, so that the cup lid 20 is fixed on the cup body 10 through the clamping cooperation between the clamping ring 21 and the fixed flange 16; and the hard transition body 13 and the hard support body 12 are tightly fitted through the fixed flange 16, so that the fit between the hard support body 12 and the hard transition body 13 is tighter.

[0044] See also Figure 1-6 To further illustrate the technical solution of the present invention, the present invention provides a process for manufacturing a beverage cup, which is used to manufacture the beverage cup using composite materials to achieve the bottom heat conduction effect as described above, comprising the following steps:

[0045] Step 1: Prepare raw materials. Select food-grade silicone that meets food contact safety standards as the raw material for making the soft heat-resistant body 11, and select food-grade safe PP or PLA as the raw material for making the hard support body 12 and the hard transition body 13.

[0046] Step 2: Silicone mixing: Mix 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 product is uniform during subsequent processing and use;

[0047] Step 3, forming the soft heat-resistant body 11, making a corresponding mold according to the designed shape and size of the soft heat-resistant body 11, adding a certain amount of the mixed silicone raw material into the mold, and then placing the mold into a pressing device, performing vulcanization molding at 120° C.-140° C., and finally forming the soft heat-resistant body 11 after vulcanization molding;

[0048] Step 4: forming the rigid support body 12 and the rigid transition body 13. According to the designed shapes and sizes of the rigid support body 12 and the rigid transition body 13, corresponding molds are made, and the PP or PLA raw material is heated to a molten state and then injected 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. After injection, the raw material is cooled and solidified, and demolded after molding to obtain the rigid support body 12 and the rigid transition body 13.

[0049] 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 putting the formed soft heat-resistant body 11 upside down on the conveying jig. The conveying jig is transferred 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. After the heat-resistant glue is applied, it is transferred to the mold for forming the hard transition body 13. The formed hard transition body 13 is put on the outside of the soft heat-resistant body 11 coated with glue by a robot or manually, and then transferred 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;

[0050] Step 6, assemble the cup body 10, and use a mold to form a wavy fixed structure on a section of the hard support body 12 and the hard transition body 13. After the soft heat-resistant body 11 and the hard support body 12 are bonded together, the hard support body 12 is then put on the initial finished product, so that the hard support body 12 and the soft heat-resistant body 11 are clamped and fixed by the wavy fixed structure to form the cup body 10.

[0051] That is, in the process of making the cup body 10 of the present invention, traditional mold forming is used to complete the process by bonding and assembly. 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, thereby making the production cost of the cup body 10 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.

[0052] 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 invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
