Technical Field

[0001] The utility model relates to the technical field of packaging, and in particular to a lightweight injection-molded cup and packaging. Background Art

[0002] Injection-molded cups are manufactured using the injection molding process. Plastic pellets are melted into a fluid, then injected into a mold using an injection molding machine. After cooling, the cups are formed. Injection-molded cups are typically made of polypropylene (PP), a material with high heat resistance, excellent mechanical properties, and chemical stability. This molding method ensures a compact, durable structure that can withstand certain temperature fluctuations.

[0003] Currently, injection molded cups are usually cylindrical. During the production process, the thickness of the cup body is usually increased to avoid the problem of easy deformation of the cup body. However, this method uses more injection molding materials and increases costs.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a lightweight injection molded cup and packaging that can improve or solve the above technical problems. The lightweight injection molded cup can meet the cup body strength requirements while reducing the use of injection molding materials, reducing costs and achieving a lightweight effect.

[0014] When the total number of reinforcing ribs is greater than 4 and not more than 16, the height of each reinforcing rib is at least 80% of the height of the cup surface.

[0015] In an optional embodiment, the cross-sectional shape of each reinforcing rib independently includes at least one of a straight line and a curved line.

[0016] In an optional embodiment, the width of the cup body gradually increases from close to the cup bottom to away from the cup bottom.

[0032] Example

[0033] The utility model provides a lightweight injection molded cup 100, combined with Figures 1 to 4 The lightweight injection molded cup 100 includes a cup bottom 10 and a cup body 20 , and the cup bottom 10 is connected to the bottom of the cup body 20 .

[0034] The cup body 20 includes a plurality of cup surfaces 21 connected end to end. The connection between any two adjacent cup surfaces 21 has a reinforcing ridge 22 , and the thickness of the reinforcing ridge 22 is greater than the thickness of any cup surface 21 of the two cup surfaces 21 connected to the reinforcing ridge 22 .

[0035] It should be noted that conventional cylindrical injection-molded cups usually require the cup surface 21 to be thickened to meet strength requirements, but this method will greatly increase costs.

[0036] In this embodiment, the cup body 20 is designed to be relatively thin, with thickness increased only at the reinforcing ribs 22. By providing the reinforcing ribs 22 at the junction of two adjacent cup surfaces 21, the cup body 20 is strengthened, making it more rigid when held, and preventing deformation even when the cup surfaces 21 are relatively thin. Furthermore, the thinner cup surfaces 21 effectively reduce the use of injection molding material, which not only helps reduce costs but also achieves a lightweight effect.

[0037] In some optional embodiments, the thickness of the reinforcing rib 22 is d1, the thickness of any cup surface 21 of the two cup surfaces 21 connected to the reinforcing rib 22 is d2, and the difference between d1 and d2 does not exceed 40% of d1. In other words, the thickness difference between the cup surface 21 and the reinforcing rib 22 does not exceed 40% of the thickness of the reinforcing rib 22.

[0038] In specific settings, the difference between d1 and d2 can be 1% d1, 2% d1, 5% d1, 8% d1, 10% d1, 12% d1, 15% d1, 18% d1, 20% d1, 22% d1, 25% d1, 28% d1, 30% d1, 32% d1, 35% d1, 38% d1 or 40% d1, etc., or it can be other values ​​greater than d1 and not exceeding 40% d1.

[0039] Setting the thickness of the reinforcing rib 22 within the above range can neither increase the thickness too much nor provide sufficient strength guarantee, and can also ensure stability.

[0040] In some optional embodiments, the thickness of any cup surface 21 of the two cup surfaces 21 connected to the reinforcing edge 22 can be 0.5mm to 2mm, such as 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm or 2mm, or other values ​​within the range of 0.5mm to 2mm.

[0041] In some typical embodiments, the thickness of any cup surface 21 of the two cup surfaces 21 connected to the reinforcing rib 22 is 0.5 mm to 1 mm.

[0042] In some optional embodiments, the thickness of all cup surfaces 21 is equal. In some optional embodiments, the thickness of all reinforcing ribs 22 is equal.

[0043] For example, in some typical embodiments, the thickness of all cup surfaces 21 is 0.5 mm, and the thickness of all reinforcing ribs 22 is 0.8 mm.

[0044] In addition, in some other optional embodiments, the situation that the thicknesses of the cup surfaces 21 are different is not excluded. Similarly, the situation that the thicknesses of the reinforcing ribs 22 are different is not excluded.

[0045] In some optional embodiments, all the reinforcing ribs 22 are spaced apart from each other.

[0046] Preferably, all the reinforcing ribs 22 are distributed at equal intervals along the circumference of the cup body 20 to provide relatively uniform support strength for each position of the cup body 20 .

[0047] In some optional embodiments, the total number of the reinforcing ribs 22 is not less than 3, and correspondingly, the total number of the cup surface 21 is not less than 3.

[0048] In some preferred embodiments, the total number of reinforcing ribs 22 is not less than 3 and less than 16, such as 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15. Accordingly, the total number of surfaces of the cup surface 21 is not less than 3 and less than 16.

[0049] In some more preferred embodiments, the total number of reinforcing ribs 22 is 3 to 10, such as 3, 4, 5, 6, 7, 8, 9, or 10. Accordingly, the total number of faces of the cup surface 21 is 3 to 10. In this more preferred embodiment, the entire injection-molded cup has a more significant weight reduction effect.

[0050] In some preferred embodiments, in order to obtain a better strength effect, the height range of the reinforcing rib 22 can be set as follows:

[0051] When the total number of the reinforcing ribs 22 is three, the height of each reinforcing rib 22 is preferably equal to the height of the cup surface 21 .

[0052] When the total number of reinforcing ribs 22 is 4, the height of each reinforcing rib 22 is at least 90% of the height of the cup surface 21, such as 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 100% of the height of the cup surface 21, or other values ​​within the range of 90% to 100%.

[0053] When the total number of reinforcing ribs 22 is greater than 4 and not more than 16, the height of each reinforcing rib 22 is at least 80% of the height of the cup surface 21, such as 80%, 82%, 85%, 88%, 90%, 92%, 95%, 98% or 100% of the height of the cup surface 21, or other values ​​within the range of 80% to 100%.

[0054] It should be noted that, in the present invention, the above-mentioned “height of the reinforcing rib 22 ” can be understood as “the length of the reinforcing rib 22 extending from the cup bottom 10 to the cup mouth”.

[0055] Under the above solution, it is possible to reduce material usage (reduce product weight) and cost while ensuring that the injection-molded cup has sufficient strength and stiffness.

[0056] In some optional embodiments, the cross-sectional shape of each reinforcing rib 22 independently includes at least one of a straight line and a curved line.

[0057] The straight line type may include a single straight line type or a broken line type formed by multiple straight lines, etc. The curved line type may include a single arc type or a wavy shape formed by multiple arcs, etc.

[0058] When the cross-section of the reinforcing edge 22 is a single arc, the vertex of the arc faces the cup surface 21. For example, the arc is a circular arc, and the radius of the circular arc can be 2mm to 10mm, such as 2mm, 4mm, 6mm, 8mm or 10mm, or other values ​​within the range of 2mm to 10mm.

[0059] By setting the cross section of the reinforcing rib 22 to be curved, a smooth transition can be achieved.

[0060] In addition, the reinforcing ribs 22 may be configured into other shapes as needed, which are not limited here.

[0061] In some optional embodiments, the width of the cup body 20 gradually increases from the direction close to the cup bottom 10 to the direction away from the cup bottom 10, that is, it is larger at the top and smaller at the bottom. In addition, other shapes of the cup body 20 are not excluded.

[0062] During actual production, the reinforcing ribs 22 and the cup surface 21 are integrally injection-molded.

[0063] In some specific embodiments, the cup body 20 of the lightweight injection molded cup 100 is shaped larger at the top and smaller at the bottom. There are 6 reinforcing ribs 22 in the cup body 20, and the total number of cup surfaces 21 is 6. The thickness of each reinforcing rib 22 is 0.8 mm, and the thickness of each cup surface 21 is 0.5 mm. The height of each reinforcing rib 22 is equal, and the height of each cup surface 21 is also equal. The 6 reinforcing ribs 22 are equidistantly spaced from each other, and the height of each reinforcing rib 22 is equal to the height of each cup surface 21. The bottom end of each reinforcing rib 22 (the end connected to the cup bottom 10) is arc-shaped (the arc radius is 3 mm).

[0064] As mentioned above, this embodiment provides a method for reducing weight while ensuring sufficient strength and resistance to deformation. This can also be understood as follows: the lightweight injection molded cup 100 provided by this utility model is a thin-walled injection molded cup with non-uniform wall thickness. By increasing the thickness of the reinforcing edges (smaller area) to enhance the strength of the shape, and reducing the thickness of the cup surface (larger area), the material used is reduced, thereby achieving the required strength and achieving lightweight packaging without affecting the user experience.

[0065] Example 2

[0066] The utility model provides a package, which includes a cup cover and the lightweight injection molded cup 100 in Example 1. The cup cover is detachably covered on the cup mouth of the lightweight injection molded cup 100.

[0067] The above packaging can be applied to various contents. For example, the contents can be dairy products, such as milk, yogurt or ice cream, or juice, coffee, tea, milk tea or rice cereal.

[0068] In some optional embodiments, the package can also be used with a straw, a stirring stick, etc.

[0069] Accordingly, the cup cover may be provided with an opening, which can be used for direct inhalation by the user or for insertion of a straw and / or a stirring rod.

[0070] In addition, the package can also be equipped with a cap, which can selectively close the opening of the cup lid, that is, when the cap is placed on the opening, the entire package is in a closed state; when the cap is removed, the opening is exposed.

[0071] In addition, the above packaging can also be used in conjunction with a spoon. For example, the spoon is detachably connected to the cup lid, or detachably connected to the back of the cup bottom.

[0072] In summary, the lightweight injection-molded cup 100 provided by the present invention can meet the strength requirements of the cup body 20 while also reducing the use of injection molding materials, lowering costs and achieving a lightweight effect. The lightweight injection-molded cup 100 can be paired with a cup lid to form a package and is suitable for holding a variety of contents, thus having high promotion and application value.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
