Abstract

The utility model relates to a hard material packing box, comprising a box body and a box cover. The box cover is composed of a top part and a cover edge vertically extending from the edge of the top part. The hard material packing box is characterized in that an open convex ring is arranged in an included angle between the cover edge of the inner side of the box cover and the top part, and a force application indicating part is arranged at the top edge of the box cover positioned at the opening part of the convex ring. When the box cover covered with the box body tightly needs to open, since the force application part is arranged at the a space position between two contiguous convex blocks, a height distance is formed between the top part of the inner side of the box cover near the cover edge and the bottoms of the convex blocks (namely the opening edge of the box body), and pressure difference is formed. The force application principle of lever is utilized when applying force here, the force application indicating position is pressed by hands, and the box cover can be opened by the old and the young via light force with convenience.

Description

Hard material packing box

Technical field

The utility model relates to a kind of packing box, relates in particular to a kind of hard material packing box.

Background technology

In order to prevent the influence of external environment to article quality, some article needs can in packing can and box.The general employing of existing hard material packing box is made of box body and the lid adaptive with it, and when covering, the box body oral area is against the top of lid inner wall edge, so that lid tightly covers on box body, keeps article permanency matter in the box.But also there is following shortcoming in the current packaging box: because the compactness between box body and the lid, when lid tightly covers on box body and requires great effort very much when wanting to open, especially difficult more for old person and child.

Summary of the invention

The utility model is in order to solve existing packing box when lid covers when tight difficult problem of separating from box body, and a kind of novel hard material packing box that provides, this packing box needs only part specific on the lid application of force slightly, just can make lid and box body, and is very convenient, practical.

The technical scheme that the utility model is taked is: a kind of hard material packing box, comprise box body, lid, and described lid constitutes by caping and from the lid limit that the caping edge-perpendicular is extended; Be characterized in, be provided with an open protruding circle between the lid limit of described lid inner face and the angle that caping is connected, the lid top margin that is positioned at this protruding circle opening is provided with application of force indication position.

In the above-mentioned hard material packing box, the protruding circle of the opening that is provided with between the lid limit of described lid inner face and the angle that caping is connected is made of an elongated projection, is provided with application of force indication position between two open ends of this projection.

In the above-mentioned hard material packing box, the protruding circle of the opening that is provided with between the lid limit of described lid inner face and the angle that caping is connected is made of the projection at a plurality of intervals, is provided with application of force indication position between every adjacent projection.

Because the utility model has adopted above structure, when the lid lid is tightly wanted to open on box body, as long as finger is in the application of force indication position application of force, because force application part is the interval at projection, the lid inner face closely covers between the caping on limit and the projection bottom a height distance, forms difference of pressure, therefore if the very little strength of cost lid can be opened, all-ages, conveniently freely.

Description of drawings

Concrete structure of the present utility model is further provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a decomposing schematic representation of the present utility model;

Fig. 2 is the structural representation of the lid inner face of a kind of embodiment of the utility model;

Fig. 3 is the A-A portion view of Fig. 2;

Fig. 4 is the structural representation of the lid inner face of the another kind of embodiment of the utility model;

Fig. 5 is the tight structural representation when box body of the utility model lid lid;

Fig. 6 is the view that lid separates with box portion after the application of force of application of force indication position.

The specific embodiment

See also Fig. 1.A kind of hard material packing box of the utility model can adopt the metal sheet punching press to constitute, and comprises box body 1, lid 2, and the oral area of box body has a circle chimb 11, and lid 2 constitutes by caping 21 and from the lid limit 22 that the caping edge-perpendicular is extended.

See also Fig. 2, Fig. 3.Be provided with an open protruding circle 3 between the lid limit of described lid inner face and angle that caping is connected, this protruding circle can constitute (as shown in Figure 3) by an elongated projection, also can be made of (as shown in Figure 4) the projection at a plurality of intervals.Present embodiment adopts metal sheet to be stamped to form, and therefore can directly go out a circle projection (as shown in Figure 3) when punching press in lid, can make technology easy like this.Certainly also can between the lid limit of lid inner face and angle that caping is connected, fill the hard material formation.

See also Fig. 5.When lid covered on the box body, the protruding circle 3 in the lid was tight against on the chimb 11 of box body oral area (as shown in phantom in FIG.).

Please cooperate and consult Fig. 4, Fig. 5.The utility model between this protruding circle opening or adjacent two projections at interval the lid top margin at position be provided with application of force indication position 6.

When the lid lid is tightly wanted to open on box body, because force application part is the interval at two adjacent projections, the lid inner face closely covers between the bottom (also be box body mouth limit) of the caping and the projection on limit a height distance H, form difference of pressure, the application of force is especially as utilizing the principle application of force of lever herein, therefore as long as hand is indicated position 6 by the application of force, no matter the very little strength F of old and young cost can open lid a mouth, " 0 " state as shown in Figure 6, gently lid is taken down getting final product then, freely very convenient.

Claims
