Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, and in particular relates to a film sealing box with a double opening structure. Background Technology

[0002] Film-sealed boxes are widely used in the packaging of food, medicine, family planning products and other goods due to their good sealing and preservation capabilities. Traditional film-sealed boxes are usually opened by tearing the edge of the film. Users need to find and pinch the edge of the film and then apply tearing force to tear the film open.

[0003] However, traditional packaging opening methods have many inconveniences: it is difficult for users with wet, weak, or other hands to pinch and tear the thin film; the tearing process may cause liquid inside the box to splash out or the contents to be squeezed out; tearing requires the use of both hands, which is extremely inconvenient in mobile scenarios or when one hand is occupied.

[0004] Therefore, there is an urgent need for a film sealing box structure that can be more convenient and reliable, especially one-handed opening, without significantly increasing costs and process complexity. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a film sealing box with a dual opening structure, which aims to solve the problems mentioned in the background art.

[0006] This utility model embodiment is implemented as follows: a film sealing box with a dual opening structure includes:

[0007] The box body has an outer edge for the box opening;

[0008] A sealing film is used to seal the sealing area on the outer edge of the box opening.

[0009] The tear-off area is located on one side of the outer edge of the box opening. The sealing film can be separated from the box body by tearing the tear-off area to open the box.

[0010] Pre-crack line two is set on the outer edge of the box opening, away from the sealing area of ​​the sealing film. It is located on both sides of the outer edge of the box opening, along with the tear-off area. Breaking the pre-crack line two separates the outer edge of the box opening from the box body, thus opening the box.

[0011] Preferably, the second pre-splitting line is located on the outer edge of the box opening, near the box body.

[0012] Preferably, the tearing position is a pre-crack line one, which is located at the edge of the outer edge of the box opening. Breaking the pre-crack line one causes the outer edge of the box opening to separate, and the separated part is connected to the sealing film.

[0013] Preferably, the tear-off area is the part of the outer edge of the box opening that is not sealed to the sealing film.

[0014] Preferably, the tear-off area is a groove located on one side of the outer edge of the box opening, and the groove is not sealed to the sealing film.

[0015] This utility model provides a film sealing box with a dual opening structure, which has two opening methods. It retains the familiar and reliable traditional tearing method, while also providing a one-handed lever opening method to meet different user preferences and usage scenarios.

[0016] Convenient: Utilizing the lever principle, it can be opened by simply pulling upwards with one hand, providing users with another way to open it with just one hand, while also increasing the opening speed;

[0017] Simple structure and low cost: The opening structure is directly integrated into the box body through mold design, without the need to add any extra parts, and hardly increases the production cost.

[0018] High safety: The lever opening mechanism allows for controllable force and clear direction, effectively reducing the risk of contents spilling out due to excessive force or improper tearing direction. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 2 The diagram shown illustrates the structure of a film sealing box with a dual-opening structure, according to an embodiment of the present invention, comprising:

[0029] Box body 1, wherein the box body 1 is provided with an outer edge 2 of the box opening;

[0030] The sealing film 3 is sealed to the sealing area 6 on the outer edge 2 of the box opening;

[0031] A tear-off area is located on one side of the outer edge 2 of the box opening. The sealing film 3 is separated from the box body 1 by tearing through the tear-off area to open the box.

[0032] Pre-crack line 2 5 is set on the side of the outer edge 2 of the box opening away from the sealing area 6 of the sealing film. It is located on both sides of the outer edge 2 of the box opening, along with the tear-off position. Breaking the pre-crack line 2 5 separates the outer edge 2 of the box opening from the box body 1, thus opening the box.

[0033] In one embodiment of this utility model, the film sealing box with a dual opening structure addresses the problems raised in the prior art by providing two opening structures: a tear-off section and a pre-splitting line 5. The first opening method is to pinch the tear-off section with your fingers and tear it to separate the sealing film 3 from the box body 1, thereby opening the box. The second opening method is to apply an upward force to the outer edge 2 of the box opening, and use the lever principle to break the pre-splitting line 5, thereby separating the outer edge 2 of the box opening from the box body 1, thereby opening the box.

[0034] The body 1 and the outer edge 2 of the box opening can be made of plastic, metal or a malleable composite material, and can be integrally formed by injection molding, vacuum forming or stamping. Different thicknesses can be used depending on the characteristics of the contents to be stored. The horizontal cross-section of the body 1 and the outer edge 2 of the box opening can be different shapes such as round, avocado, heart, square, etc. The cavity of the body 1 can be used to store solid, liquid, gas or mixed forms of food, medicine, medical devices and other items.

[0035] like Figure 2 , 4 As shown in Figures 6 and 7, in a preferred embodiment of this utility model, the pre-splitting line 25 is located on the outer edge 2 of the box opening, on the side close to the box body 1.

[0036] The second pre-crack line 5 is located near the connection between the box body 1 and the outer edge 2 of the box opening, and does not overlap with the sealing area 6 of the sealing film. The depth of the second pre-crack line 5 is 20%-80% of the thickness of the outer edge 2 of the box opening. It can be cut by molding or laser cutting. The second pre-crack line 5 can be continuous or discontinuous, and can be a single line or multiple lines. The cross-section of the second pre-crack line 5 can be V-shaped or U-shaped. Since the second pre-crack line 5 is not on the box body 1, it will not affect the overall strength of the box body 1. The box body 1 will not break and be damaged when it is squeezed.

[0037] like Figures 1 to 2 As shown, in another preferred embodiment of the present invention, the tearing position is a pre-crack line 4, which is located at the edge of the outer edge 2 of the box opening. Breaking the pre-crack line 4 causes the edge of the outer edge 2 of the box opening to separate, and the separated part is connected to the sealing film 3.

[0038] Breaking the pre-crack line 4 separates the outer edge 2 of the box opening from the edge part. The detached part is connected to the sealing film 3. You can then open the box by pinching the detached part and applying upward force, and by tearing the sealing film 3.

[0039] like Figures 3 to 4 As shown, in a preferred embodiment of this utility model, the tear-off area is the part of the outer edge of the box opening 2 that is not sealed and connected to the sealing film 3.

[0040] The part of the outer edge 2 of the box opening that is not sealed with the sealing film 3 can also be used as a tearing point. The sealing film 3 can be torn open by pinching the unsealed part of the sealing film 3.

[0041] like Figures 5 to 6 As shown, in a preferred embodiment of the present invention, the tear-off position is a groove provided on one side of the outer edge of the outer edge 2 of the box opening, and the groove is not sealed to the sealing film 3.

[0042] Alternatively, a groove can be provided on the outer edge of the box opening 2, so that the outer edge of the box opening 2 is not sealed with the sealing film 3. The box can then be opened by pinching and tearing the sealing film 3 to separate it from the box body 1.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
