Description

Technical Field

[0001] This utility model relates to the field of paper cup technology, specifically a lightweight three-layer cup. Background Technology

[0002] Paper cups are portable containers made primarily of paper, designed for single use, and widely used for serving beverages and simple foods. Their core structure typically consists of a cylindrical or frustum-shaped body and a base. Based on their use, they can be categorized as room-temperature drinking cups, hot beverage cups (such as coffee cups), and food packaging boxes. They offer advantages such as low cost, lightweight, biodegradability (some eco-friendly models), and no need for washing, making them common containers for food delivery, offices, and exhibitions. Customized designs are also available for holidays and brand promotions.

[0003] However, existing paper cups are not sufficiently heat-insulating and scalding-proof, causing the outer layer to get hot when holding hot drinks and condensation to form when holding cold drinks, leading to the paper cup becoming damp. In addition, paper cups have no shock resistance, making it easy for drinks to shake. Therefore, we have proposed a lightweight three-layer cup to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a lightweight three-layer cup that solves the problem of insufficient heat insulation and anti-scalding properties, which results in the outer layer becoming too hot for users to handle when holding hot drinks, and condensation easily forming when holding cold drinks, leading to the paper cup becoming damp; at the same time, the paper cup has no shock resistance, making it prone to the risk of drinks shaking.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a lightweight three-layer cup, comprising a cup body, the cup body comprising an inner cup paper, the outer wall of the inner cup paper being provided with a heat insulation layer, and the outer wall of the heat insulation layer being provided with an outer cup paper.

[0006] Preferably, both the inner and outer cup paper are made of paper.

[0007] Preferably, the heat insulation layer is made of a material similar to pearl cotton.

[0008] Preferably, the inner cup paper, the heat insulation layer, and the outer cup paper are bonded and laminated together by food-grade hot melt adhesive.

[0009] Preferably, the thickness of the heat insulation layer is greater than the thickness of the inner cup paper and the outer cup paper.

[0010] Preferably, the main view shape of the heat insulation layer is the same as that of the outer cup paper, both being fan-shaped.

[0011] Preferably, the outer wall of the outer cup paper is printed with a pattern or a solid color.

[0012] Beneficial effects This invention provides a lightweight three-layer cup. Compared with the prior art, it has the following advantages: This lightweight three-layer cup, composed of an inner paper cup, an insulation layer, and an outer paper cup, breaks through the limitations of traditional single-layer paper cups. Because the insulation layer is made of a pearl-cotton-like material, it effectively blocks heat transfer, keeping the outer layer cool to the touch when holding hot drinks, and reduces condensation when holding cold drinks, keeping the cup dry. The pearl-cotton-like material also provides slight shock absorption, reducing the risk of drinks shaking. Therefore, this lightweight design makes it suitable for hot beverage scenarios (recommended for coffee, tea, and other scenarios requiring heat protection and insulation in winter), cold beverage scenarios (suitable for takeaway cold drinks from milk tea shops, preventing ice water from seeping into and staining tabletops), and business / office scenarios (as a meeting tea cup, replacing traditional ceramic cups and reducing the risk of breakage). This allows the cup to precisely target the urban fast-moving consumer goods market and address the pain points of existing beverage packaging with its differentiated design.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 3 This utility model provides a technical solution: a lightweight three-layer cup, including a cup body 1, the cup body 1 including an inner cup paper 2, an outer wall of the inner cup paper 2 being provided with a heat insulation layer 3, an outer cup paper 4 being provided on the outer wall of the heat insulation layer 3, and the heat insulation layer 3 being made of a pearl cotton-like material. The three-layer cup body 1, composed of an inner cup paper 2, a heat insulation layer 3, and an outer cup paper 4, breaks through the limitations of traditional single-layer paper cups. Because the heat insulation layer 3 is made of a pearl cotton-like material, it not only blocks heat transfer, preventing the outer layer from getting hot when holding hot drinks, but also reduces condensation when holding iced drinks, keeping the cup dry. Simultaneously, the pearl cotton layer provides slight shock absorption, reducing the risk of drinks shaking. Therefore, this lightweight cup body 1 is suitable for hot beverage scenarios (recommended for coffee, tea, and other scenarios requiring heat protection and winter beverage insulation), cold beverage scenarios (suitable for takeaway iced drinks from milk tea shops, preventing ice water from seeping into and staining tabletops), and business / office scenarios (as a meeting tea cup, replacing traditional ceramic cups and reducing the risk of breakage). This allows the cup body 1 to precisely target the urban fast-moving consumer goods market and address the pain points of existing beverage packaging through differentiated design.

[0017] See Figure 1 - Figure 3 Both the inner cup paper 2 and the outer cup paper 4 are made of paper, which facilitates the processing of paper cups.

[0018] See Figure 1 - Figure 3 The inner cup paper 2, the heat insulation layer 3, and the outer cup paper 4 are bonded together by food-grade hot melt adhesive, which can ensure the structural strength of the three-layer bonding and prevent the migration of harmful substances. The food-grade hot melt adhesive can be EVA type hot melt adhesive or PA type hot melt adhesive, etc.

[0019] See Figure 1 - Figure 3 The thickness of the insulation layer 3 is greater than that of the inner cup paper 2 and the outer cup paper 4, which ensures the thickness of the insulation layer 3 and thus improves its effect of blocking temperature transfer and reducing condensation.

[0020] See Figure 1 - Figure 3 The main view shape of the heat insulation layer 3 is the same as that of the outer cup paper 4. Both are fan-shaped, which makes it easy to bond the outer cup paper 4 to the outer wall of the heat insulation layer 3, thus making the two consistent and improving the appearance of the paper cup.

[0021] See Figure 1 - Figure 3 The outer wall of the outer cup paper 4 can be printed with patterns or solid colors, thus meeting modern aesthetic needs and strengthening brand recognition and communication, achieving low-cost expansion of brand exposure.

[0022] When in use, the three-layer cup body 1, composed of an inner cup paper 2, a heat insulation layer 3, and an outer cup paper 4, breaks through the limitations of traditional single-layer paper cups. Because the heat insulation layer 3 is made of a pearl cotton-like material, it not only blocks heat transfer, preventing the outer layer from getting hot when holding hot drinks, but also reduces condensation when holding cold drinks, keeping the cup dry. Simultaneously, the pearl cotton-like material layer provides slight shock resistance, reducing the risk of drinks shaking. Therefore, this lightweight cup body 1 is suitable for hot drink scenarios (recommended for coffee, tea, and other scenarios requiring heat protection and winter beverage insulation), cold drink scenarios (suitable for takeaway cold drinks from milk tea shops, preventing ice water from seeping into and staining tabletops), and business / office scenarios (as a meeting tea cup, replacing traditional ceramic cups and reducing the risk of breakage). This allows the cup body 1 to precisely target the urban fast-moving consumer goods market and address the pain points of existing beverage packaging through differentiated design.

[0023] In summary, this device breaks through the limitations of traditional single-layer paper cups by layering materials, and meets the requirements of hot beverage safety and cold beverage cleanliness, while seeking commercial application space by balancing environmental protection, practicality and cost-effectiveness.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
