Description

Technical Field

[0001] This utility model belongs to the field of coffee packaging technology, and in particular relates to a packaging can. Background Technology

[0002] As living standards improve, people often drink coffee to stay alert after long hours of tiring work.

[0003] During coffee processing, to reduce oxidation and maintain flavor fidelity, freeze-drying technology is often used to create freeze-dried coffee blocks using freeze-drying molds. Freeze-dried coffee blocks are less prone to spillage, making it easier to control the amount used per serving, and they do not require the addition of anti-caking agents.

[0004] Freeze-dried coffee blocks require freeze-drying molds for production, but the freeze-dried coffee blocks made in these molds need to be unmolded and packaged. This unmolding and packaging process can easily lead to breakage of the freeze-dried coffee blocks. Furthermore, the freeze-drying molds require additional demolding devices, resulting in higher costs. Therefore, the technical problem this invention aims to solve is how to design a technology that reduces breakage of freeze-dried coffee blocks due to unmolding and packaging while lowering manufacturing costs. Utility Model Content

[0005] This invention provides a packaging can that reduces the breakage of freeze-dried coffee blocks due to molding and packaging, and also reduces manufacturing costs.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] In the first aspect, this utility model provides a packaging can, comprising:

[0008] The tank has an opening at one end, and an internal cavity is formed inside the tank. The inner wall of the cavity has a cylindrical curved surface structure, and the outer wall of the tank has a circumferential edge at the opening end of the tank.

[0009] The can lid has a locking protrusion formed on its inner wall surface at a position corresponding to the edge. The locking protrusion is adapted to the edge, and the can lid and the can body are detachably connected through the locking protrusion and the edge.

[0010] In some embodiments of this application, a receiving groove is formed at the junction of the edge and the outer wall of the tank, and the receiving groove is configured to receive the card protrusion.

[0011] In some embodiments of this application, a filling line is provided on the inner wall surface of the tank.

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0032] In the first aspect, combining Figures 1 to 5 As shown, this embodiment of the present disclosure provides a packaging can for holding coffee liquid. As a freeze-drying container, it can be used to make freeze-dried coffee blocks. The packaging can includes a can body 1 and a can lid 2.

[0033] Combination Figure 2 and Figure 3 As shown, one end of the can 1 has an opening, and the other end of the can 1 is a closed structure. The interior of the can 1 forms a receiving cavity 13, which is connected to the opening end 11 of the can 1. The inner wall of the receiving cavity 13 has a cylindrical curved surface structure. When in use, by pointing the opening end 11 of the can 1 vertically downward, the freeze-dried coffee block will be poured out of the can 1 due to gravity.

[0034] The outer wall of the tank body 1 has a circumferential edge 12 at the open end 11 of the tank body 1.

[0035] A locking protrusion 21 is formed on the inner wall surface of the can lid 2 at a position corresponding to the edge 12. The locking protrusion 21 is adapted to the edge 12. The can lid 2 and the can body 1 are detachably connected by the locking protrusion 21 and the edge 12. The can lid 2 and the can body 1 are locked together, which makes it easy to open or close the can lid 2 and avoids the failure of the threaded connection in the prior art.

[0036] Specifically, the packaging can includes a can body 1 and a can lid 2. One end of the can body 1 has an opening, and the interior of the can body 1 forms a receiving cavity 13. The inner wall of the receiving cavity 13 has a cylindrical curved surface structure, which is relatively smooth and has a uniform inner diameter. When the freeze-dried coffee block needs to be removed, it is not easy to damage the surface of the freeze-dried coffee block, which helps to ensure its integrity. The outer wall of the can body 1 has a circumferential edge 12 at the opening end 11 of the can body 1. The inner wall of the can lid 2 has a locking protrusion 21 at the position corresponding to the edge 12. The locking protrusion 21 is adapted to the edge 12. The can body 1 directly serves as a freeze-drying container to achieve integrated freeze-drying, eliminating the need for repackaging and molding. This avoids damage to the freeze-dried coffee block due to repackaging and molding, and eliminates the need for additional demolding devices, which helps to reduce production costs. At the same time, the can body 1 can also be used as a drinking container, which makes it convenient for users to directly drink concentrated coffee liquid. It has a simple structure and beautiful appearance.

[0037] Specifically, the edge 12 protrudes from the opening end 11 of the can body 1. On the one hand, the edge 12 can provide a point of leverage, making it easier for users to pick up the can body 1. On the other hand, the edge 12 facilitates the can body 1 and the can lid 2 to be closed together, which is convenient for processing and manufacturing.

[0038] Specifically, the lid 2 is sealed to the body 1, that is, when the lid 2 and the body 1 are snapped together, the body 1 and the lid 2 can form a sealed space.

[0039] In some embodiments of this application, a receiving groove 14 is formed at the junction of the edge 12 and the outer wall surface of the tank 1, and the receiving groove 14 is configured to receive the card protrusion 21.

[0040] Specifically, a receiving groove 14 is formed at the connection between the edge 12 and the outer wall of the tank 1. The receiving groove 14 can accommodate the latching protrusion 21, which helps to save space and makes the tank 1 and the lid 2 fit more tightly.

[0041] In some embodiments of this application, a filling line is provided on the inner wall surface of the tank 1.

[0042] Specifically, by setting up filling lines, a standard can be provided for the amount of liquid coffee to be filled, avoiding the injection of too much or too little.

[0043] In some embodiments of this application, the filling line is an annular groove formed on the inner wall surface of the can 1.

[0044] Specifically, by setting the filling line as an annular groove on the inner wall of the tank 1, it is easier to process and manufacture. At the same time, by setting the filling line inward, it is not easy to damage the outer surface of the freeze-dried coffee block when it is necessary to pour it out, which helps to ensure the overall integrity of the freeze-dried coffee block.

[0045] In some embodiments of this application, combined with Figure 5As shown, the filling line includes a first scale line 15 and a second scale line 16, which are spaced apart, with the first scale line 15 located below the second scale line 16.

[0046] Specifically, during the freeze-drying process, the internal moisture of the coffee liquid will form ice crystals. These ice crystals will expand the coffee solid matter, forming a porous framework and causing volume expansion. By setting a first scale line 15 on the inner wall of the container 1, when coffee liquid is injected into the container 1, the amount injected is based on the first scale line 15 or slightly higher. This allows sufficient space to be reserved for the expansion of the coffee liquid during the freeze-drying process.

[0047] By setting a second scale line 16 on the inner wall of the container 1, when water or milk is poured into the container 1 to dissolve the freeze-dried coffee block, the second scale line 16 serves as a warning line, reminding the user not to pour water or milk beyond the second scale line 16, otherwise it will be inconvenient to pour the espresso liquid or drink the espresso liquid directly.

[0048] In some embodiments of this application, combined with Figure 4 As shown, a recess 22 is formed on the upper surface of the can lid 2, and the recess 22 is located at the center of the can lid 2.

[0049] Specifically, by setting a recessed part 22 on the upper end face of the can lid 2, the recessed part 22 can serve as a "press to unlock" trigger point. The user can press down on the recessed part 22 to break the negative pressure inside the can body 1, thereby opening the lid with one hand. This helps to solve the problem of difficulty in opening caused by excessive sealing of the packaging can.

[0050] Meanwhile, the recessed part 22 serves as a visual focal point, providing users with the cues of "press here," which helps enhance the memorability of product interactions.

[0051] In some embodiments of this application, a protrusion 17 is formed on the bottom end surface of the tank body 1 on the side facing the receiving cavity 13, and the protrusion 17 is located at the center of the bottom end surface of the tank body 1.

[0052] Specifically, during the process of adding water or milk to the container 1 to dissolve the freeze-dried coffee block, the dissolution rate of the core of the freeze-dried coffee block is the slowest. By forming a protrusion 17 on the bottom surface of the container 1 facing the receiving cavity 13, the specific surface area of ​​the freeze-dried coffee block is increased accordingly, which can improve the dissolution rate.

[0053] Specifically, a pit is formed on the bottom surface of the tank 1 opposite to the receiving cavity 13, corresponding to the protrusion 17. The pit helps the tank 1 to prevent slipping.

[0054] In some embodiments of this application, both the can body 1 and the can lid 2 are made of plastic material.

[0055] Specifically, by making both the can body 1 and the can lid 2 from plastic materials, it is easy to recycle.

[0056] For example, the tank body 1 and the tank lid 2 are made of polypropylene material, which has good low-temperature resistance, is environmentally friendly, and can be reused.

[0057] The preparation process of freeze-dried coffee blocks is as follows: inject liquid coffee into the container 1 up to the minimum filling line; then place the container 1 into the freeze-drying equipment; after the freeze-dried coffee blocks are made, inject inert gas into the container 1 and seal it with aluminum film; finally, put the lid 2 on.

[0058] Traditional freeze-drying molds require freeze-dried coffee blocks to be exposed to air for more than 30 minutes during the demolding and packaging process, which increases the risk of oxidative rancidity. In contrast, the container 1 in this application serves directly as the freeze-drying container. After the freeze-dried coffee blocks are produced, demolding and packaging are unnecessary. Inert gas is injected, and the container is sealed with aluminum foil for freshness locking before final packaging. This reduces the chance of the freeze-dried coffee blocks coming into contact with air, maximizing the preservation of flavor and freshness.

[0059] In actual use, users can inject water or milk into container 1, and the freeze-dried coffee block will dissolve to form concentrated coffee liquid, which users can then drink directly from container 1; alternatively, the freeze-dried coffee block or the dissolved concentrated coffee liquid can be poured out and diluted with water or milk for drinking.
