Description

Technical Field

[0001] This utility model relates to the field of packaging, and in particular to a milk powder cap with a folding sealing structure. Background Technology

[0002] Sealed packaging containers are a common form of packaging, often seen in milk powder and various instant products. Most existing sealed packaging containers consist of a metal container and a milk powder cap that is snapped onto the container. In order to achieve a better seal between the milk powder cap and the container, and to make it tamper-proof, packaging container manufacturers on the market have made various improvements to the packaging containers.

[0003] For example, the existing design CN208647542U discloses a sealed can lid structure that improves the sealing effect by setting a soft rubber wrapping structure between the milk powder lid and the can. However, it also has certain drawbacks, such as: 1. It is easy to open. Although the soft wrapping structure increases the sealing performance, the soft rubber structure is easier to force open, making it easier for consumers to open the can and affecting product sales. 2. It requires excessively high precision. In order to ensure the sealing performance, the dimensions between the milk powder lid and the can need to correspond precisely. However, in reality, it is difficult to avoid certain errors in the production of the can and the milk powder lid, which can easily lead to problems such as the can and the milk powder lid not fitting together properly, resulting in excessively high dimensional precision requirements during production.

[0004] To address the aforementioned issues, this solution designs a milk powder cap with a folding sealing structure. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a milk powder cap with a folding sealing structure, including: an upper cover and a cap base, wherein the upper cover is foldably connected to the cap base;

[0006] The lower edge of the cap extends downward to form a folding sealing structure. The folding sealing structure has a recessed folding groove, which divides the folding sealing structure into a fastening part and a folding part. The folding part folds upward through the folding groove to form a folded edge. The folded edge engages with the snap-fit ​​edge on the upper part of the can, thereby allowing the milk powder cap to be fastened and installed on the top of the can.

[0007] The inner diameter of the folding part gradually decreases from top to bottom, thereby forming a guide slope when the folding part is folded. The guide slope is used to guide the mouth of the can and make the folding part abut against the snap-fit ​​edge.

[0008] In this configuration, the folding portion abuts against the lower edge of the snap-fit ​​edge in the folded state, thereby pushing the can body towards the cover.

[0009] The folding indentation is V-shaped, so that when the part is folded, there is an angle between the folded part and the fastening part.

[0010] The thickness of the folded portion is 1 / 3 to 1 / 2 of that of the fastening portion.

[0011] The sealing ridge has a first platform and a second platform on its inner side. The first platform has a locking pin for engaging with the locking hole at the tail of the milk powder scoop, so that the milk powder scoop can be placed between the first platform and the second platform.

[0012] The milk powder cap is made of plastic.

[0013] The milk powder can provided by this utility model has the following beneficial effects: 1. The upper edge of the folding part of the milk powder cap abuts against the snap-fit ​​edge of the milk powder cap after folding, making the snap-fit ​​of the milk powder cap more secure. 2. It is more difficult to open. When a user wants to separate the milk powder cap from the can, they need to forcefully pry open the milk powder cap. Utilizing the elasticity of the plastic material, the folding part of the milk powder cap returns to its folded state, and this process requires applying more force to the milk powder cap. 3. The snap-fit ​​method using the folding part ensures that even if there is a certain dimensional error between the can and the milk powder cap, the two can still be firmly snapped together. This reduces the precision requirements during the production process of the milk powder cap, allows it to adapt to more can sizes, and reduces the difficulty of the process and the production cost.

[0018] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0019] like Figures 1-3As shown, a milk powder cap with a folding sealing structure includes an upper cover 11 and a cap base 12, wherein the upper cover 11 is foldably connected to the cap base 12.

[0020] The lower edge of the cover 12 extends downward to form a folded sealing structure 13. The folded sealing structure 13 has a recessed folding groove 131, and the folding groove 131 divides the folded sealing structure 13 into a fastening part 132 and a folding part 133. The folding part 133 folds upward through the folding groove 131 to form a folded edge. The folded edge can engage with the snap-fit ​​edge 21 on the upper part of the tank body, thereby allowing the cover 12 to be fastened and installed on the upper part of the tank body 2.

[0021] like Figure 2 , 3 As shown, the inner diameter of the folding part 133 gradually decreases from top to bottom, thereby forming a guide slope in the folded state. The guide slope is used to guide the opening of the can body 2 and make the folding part 133 abut against the snap-fit ​​edge 21.

[0022] When the folded portion 133 is in the folded state, it abuts against the lower edge of the snap-fit ​​edge 21, thereby pushing the can body towards the cover 12.

[0023] like Figure 4 As shown, the folding groove 131 is V-shaped, and the folding part 133 can be folded along the folding groove 131. It should be noted that after folding, the folding part 133 will not be completely tight to the side of the fastening part 132, but will form a certain angle with the fastening part 132, and finally form a folded edge. Then, the folded edge is used to fasten the lower edge of the fastening edge 21 that protrudes outward on the upper part of the can body.

[0024] With the above settings, the dimensions of the can 2 and the milk powder cap 1 have more leeway. Even if the size of the can 2 is slightly smaller than the size of the milk powder cap 1, as long as the snap-fit ​​edge 21 of the can 2 can be snapped by the folded edge, it can be tightly fastened. This reduces the precision requirements of the can 2 and the milk powder cap 1 in the production process.

[0025] Specifically, the thickness of the folding portion 133 is 1 / 3 to 1 / 2 of that of the fastening portion 132.

[0026] Specifically, the upper part of the cover 12 has a sealing protrusion 121, and the upper cover 11 has a sealing groove 111. The upper cover 11 can be fastened to the cover 12 by the cooperation of the sealing groove 111 and the sealing protrusion 121, thereby making the upper cover 11 have a stronger sealing performance when it is fastened to the cover 12.

[0027] Specifically, the inner side of the sealing ridge 121 is provided with a first platform 122 and a second platform 123. The first platform 122 is provided with a snap-fit ​​point 1221 for engaging with the snap-fit ​​hole at the tail of the milk powder scoop, so that the milk powder scoop can be placed between the first platform 122 and the second platform 123.

[0028] Specifically, the milk powder cap 1 is made of plastic, and the plastic material should have a certain elasticity. When the milk powder cap is pulled by external force, the fastening part 132 needs to expand outward using elastic force, so that the folding part 133 has space to return from the folded state. Then, the milk powder cap is pressed forcefully, so that the folding part returns from the folded state, and the milk powder cap and the can can be separated. Through the above structure, it is more difficult to open than the traditional fastening or soft packaging solution.

[0029] Operating principle:

[0030] Before using this milk powder cap, first fold the folding part 133 inward to form a folded edge, and then put the milk powder cap on the can body 2. At this time, the opening of the can body 2 gradually transitions along the guide slope formed by the folding part in the folded state until the snap-fit ​​edge 21 is pressed against the folded edge, and the can body 2 is pushed towards the cap seat by the folded edge, so that the cap seat 12 and the can body 2 are tightly fastened together.

[0031] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
