Description

Technical Field

[0001] This utility model relates to the field of sealed containers, and in particular to a container with a protective structure. Background Technology

[0002] Traditional lunch boxes typically employ a design where the lid and body fit together for a tight seal. The body uses an outward-extending sealing section at the opening to increase the sealing contact area. However, in mass production or transportation scenarios, when multiple containers are placed side-by-side, the sealing section (especially for glass containers) is prone to edge damage due to collisions, directly affecting sealing performance and lifespan. Current technologies usually mitigate this problem by thickening the sealing section or adding a buffer layer, but these solutions increase material costs or sacrifice the compactness of the sealing structure, making it difficult to balance protective effectiveness with manufacturing economics. Utility Model Content

[0003] The purpose of this invention is to provide a container with a protective structure to solve the problem of easy damage to the box body in the prior art.

[0004] The technical solution of this utility model is: a container with a protective structure, including a lid and a box, wherein the lid has a protective part that extends beyond the edge of the box when closed.

[0005] Preferably, the protective portion is formed along the circumferential extension of the cover and protrudes from the edge of the box body at the distal end away from the center of the cover.

[0006] Preferably, the box body and the lid body are made of materials with different impact resistance coefficients; wherein the box body is made of a material with a first brittleness coefficient, the lid body is made of a second deformation-resistant material, and the elastic modulus of the second deformation-resistant material is at least 3 times that of the first brittleness coefficient material.

[0007] Preferably, the box body includes a sealing portion extending outward in a circumferential direction from its open end, the top surface of the sealing portion forming a sealing surface that fits with the cover for sealing, and the sealing portion constituting the edge of the box body.

[0008] Preferably, the cover is made of silicone or plastic, and the box is made of glass.

[0009] Preferably, the protective part is integrally formed with the cover and is configured as a plane extending outward from the edge of the cover.

[0010] Preferably, the protective part is integrally formed with the cover and has a first part and a second part. The first part is configured to extend outward from the edge of the cover, and the second part forms an angle with the first part and extends toward the box.

[0011] Preferably, the protective parts are arranged in pairs on both sides of the cover, and the other two sides of the cover are provided with connecting mechanisms for detachably connecting the cover and the box.

[0012] Preferably, the connecting mechanism includes a rotating shaft disposed on the cover, the rotating shaft being connected to a buckle, the buckle having an actuating part and a fastening part;

[0013] In the locked state, the locking part abuts against the bottom end of the sealing part, thereby pressing the cover onto the box body; and the lever part forms an angle with the locking part, and a gap is formed between the lever part and the box body for a finger to be inserted.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] (1) In this application, the protective part of the cover is integrally formed and extends beyond the edge of the sealing part when closed, forming a physical shielding layer that preferentially withstands external impacts and blocks the contact path between the sealing part and the outside world. The protective part further optimizes the mold complexity and cost while ensuring multi-directional coverage of the sealing part through a split angled structure (the first part extends horizontally and the second part bends downward) or a simplified planar extension design.

[0016] (2) In the preferred embodiment of this application, the integrated molding process of the protective part and the cover reduces assembly steps and simplifies the mold structure. The combination of differentiated materials improves impact resistance while avoiding the use of high-cost engineering plastics as a whole, thus achieving a balance between performance and cost.

[0017] (3) Protective parts are symmetrically arranged on both sides of the cover, and a pivot-clamping connection mechanism is provided on the other two sides. The clamping part applies a vertical pressing force to the sealing surface when closed, which enhances the sealing reliability; the finger operation gap reserved between the lever part and the box body enables quick opening and closing with one hand, taking into account both operation convenience and structural compactness.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0026] The present invention will be further described in detail below with reference to specific embodiments:

[0027] like Figure 1 As shown, a container with a protective structure includes a lid 1 and a box 2.

[0028] The box body 2 is closed in the circumference and bottom, and an opening is formed at the top. The opening extends outward in the circumference to form a sealing part 3. The upper surface of the sealing part 3 forms a sealing surface that cooperates with the cover body 1 for sealing. This arrangement can increase the sealing area between the cover body 1 and the box body 2, but the sealing part 3 will form the edge of the box body 2.

[0029] In the manufacturing process of this application, there are scenarios where multiple containers are placed side by side. In such scenarios, the sealing parts 3 between multiple box bodies 2 are prone to collision. Since the box body 2 of this application is made of glass, it is prone to breakage during direct contact with other box bodies 2.

[0030] To address this issue, this application employs a combination of materials with different impact resistance coefficients for the box body 2 and the lid 1. Specifically, the box body 2 is made of a material with a first brittleness coefficient, and the lid 1 is made of a second deformation-resistant material, wherein the elastic modulus of the second deformation-resistant material is at least three times that of the first brittleness coefficient material. In this embodiment, the lid 1 is made of silicone or plastic and has a protective portion 4 that extends beyond the sealing portion 3 of the box body 2 when closed. This design allows the protective portion 4 to collide with external objects before the sealing portion 3, thereby protecting the sealing portion 3 from damage.

[0031] like Figure 3 As shown, in some embodiments of this application, the protective part 4 is integrally formed with the cover 1, and has a first part 41 and a second part 42. The first part 41 is configured as an outward extension of the edge of the cover 1, and the second part 42 forms an angle with the first part 41 and extends towards the box body 2. This arrangement of the protective part 4 effectively shields the sealing part 3, providing better protection for the sealing part 3.

[0032] like Figure 2 As shown, in a preferred embodiment of this application, the protective part 4 is integrally formed with the cover 1 and is configured as a flat section extending outward from the edge of the cover 1. This arrangement reduces the design difficulty of the mold and lowers the processing cost of the cover 1 while ensuring the protective effect on the sealing part 3.

[0033] In addition, protective parts 4 are provided in pairs on both sides of the cover 1. On the other two sides of the cover 1 where the protective parts 4 are not provided, there are connecting mechanisms 5, which are used to detachably connect the cover 1 to the box 2.

[0034] like Figure 4 As shown, in this embodiment, the connecting mechanism 5 includes a rotating shaft 51 disposed on the cover 1. A buckle 52 is rotatably connected to the rotating shaft 51. An actuating part 522 and a fastening part 521 are integrally formed at the end of the buckle 52 away from the rotating shaft 51. The fastening part 521 is perpendicular to the actuating part 522. When the connecting mechanism 5 is in the buckle-closed state, the fastening part 521 abuts against the bottom end of the sealing part 3, thereby applying pressure towards the box body 2 to the cover 1 and pressing the sealing surface tightly. Simultaneously, a gap is formed between the actuating part 522 and the box body 2, allowing a finger to be inserted. When it is necessary to open the cover 1, by inserting a finger into this gap and actuating the actuating part 522, the buckle 52 rotates around the rotating shaft 51, thereby disengaging the fastening part 521 from the sealing part 3 and opening the cover 1.

They should not be construed as limiting the scope of protection of this utility model.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
