Description

Snap-on combination container

The present invention relates to a combined container formed by a combination of a box body and a lid body, in particular to a snap-on combined container in which the box body and the lid body are buckled and combined with each other.

Most of the existing packaging containers use plastic or paper structures. In recent years, fresh-keeping boxes or sealed boxes with sealing lids that can be closed and sealed on the box body are extremely popular in the market. They can store goods well and prevent liquid leakage. It is very extensive, and it is usually in the form of a plastic box.

An important requirement of this type of plastic box is the reliability and stability of the combined lid and box. Known plastic box combination containers are mostly provided with corresponding inverted hooks on the periphery of the lid body to cooperate with the protruding lug-shaped flanges on the periphery of the box body. This type of fastening structure usually has two situations, one of which is The buckle is not tight and easy to loosen, and the second is that the buckle is too tight and not easy to separate. In the first combination, the undercut of the cover just fits with the flange of the box, and the gripping force is insufficient, and it is easy to be out of the hook due to the deformation of the whole body being squeezed by external force; the second is the undercut part of the cover. Due to the design, the box body is often loaded with improper handling methods, resulting in unhooking situations. Taking the second combination case, there are common structural forms such as barbs and flanges, hooked protrusions and grooves in the implementation. Usually the design of the barbs is too deep or the flanges are too protruding, or the hooks are convex. The size of the column is significantly larger than the size of the groove, which will cause resistance and difficulty in the combination of the fastening structure, and even deform the box or the cover to complete the combination; especially after the combination of funds is completed, it will also As a result, it is not easy to open and separate the box body and the cover body.

Another known buckle structure is a male and female buckle body with grooves and protruding buckles. This buckle structure belongs to the same shape of surface-to-surface contact. If the size difference is used for the forced-in combination design, its resistance Larger, it is not easy to assemble or separate. Moreover, because the buckle structure of the groove and the convex buckle must be pressed by force to achieve a complete combination, if there is no relevant structure for pressing and reinforcement, the actual use will be due to the use of If the buckle structure is deformed by pressing, the combination is not easy. Because the known technology can only achieve the closed male and female buckle design due to the consideration of demolding, it cannot break through the technology of arranging the buckle body on the side wall of the plastic box.

In order to clearly reveal the technical features of the snap-on combination container disclosed in the present invention, several embodiments are presented below to illustrate the technical features of the present invention in detail, and at the same time accompanied by drawings, so that these technical features can be highlighted.

First, please refer to Figures 1 and 2 to describe in detail the specific structure of all components of the snap-fit combination container in the first embodiment of the present invention.

In this embodiment, the snap-on combination container can be made of paper, plastic or plastic, which is formed by combining the box body 1 and the lid body 2 (see Figure 2). The specific structure of the box body 1 includes: a recessed receiving portion 11, which is formed in the center of the box body 1, and an extension portion 12, which is formed on the periphery of the opening on the top surface of the box body 1, and the cross-section is inverted. It is designed to be folded, and an inner wall area 14 is concavely formed on the outer periphery of the extension portion 12, and an inner wall baffle 141 extends upward from the inner side of the inner wall area 14 to strengthen the rigidity of the structure; at least one curved clasp 13, this embodiment In the middle, a plurality of curved clasps 13 are designed in relative positions and are formed from the inner wall area 14 of the extension portion 12 extending outward. The end of the curved clasp 13 has a cleat extension surface 131, and the clasp extension surface 131 The center of the surface is provided with a protruding buckle portion 132, and the opposite surface naturally forms a concave pressing portion 133. In addition, the joint between the curved clasp 13 and the extension portion 12 is made of plastic or paper-plastic sheets. The outer portion is gradually thinned from the inner portion, and a clasp bending portion 134 is formed which is easy to bend.

The specific structure of the cover 2 includes: an upper bulge 21, which is formed by extending a side wall surface 25 downward toward the bottom surface 24 of the cover 2, and an accommodation space formed by the bulge 21 and the receiving portion 11 , Can be used to provide accommodation and holding items; an edge portion 22 is formed on the bottom surface of the cover 2 and can fit the extension 12 of the box body 1; at least one trapezoidal buckle groove 23, trapezoidal buckle groove 23 It tapers from the notch to the bottom of the groove, that is, the structure is wide at the top and narrow at the bottom. In this embodiment, a plurality of trapezoidal buckle grooves 23 are designed in relative positions and are formed on the side wall surface 25 around the cover 2. The trapezoidal buckle grooves The upper part of 23 is an opening, and protruding force-receiving parts 231 are formed on the opposite two side walls, which can strengthen the hardness of the cover 2 and can bear the weight of the stack without being easily deformed. In addition, the inner bottom surface sandwiched by the two force-receiving reinforcement parts 231 is a sliding surface 233 (see Fig. 3 at the same time), so that the fastening part 132 can be pressed against the sliding surface 233 after being buckled into the trapezoidal buckle groove 23. Anti-slip effect to avoid loosening.
