Description

The element improvement construction of packing box

Technical field

The utility model is relevant with packing box, and construction is improved more particularly to a kind of element of packing box.

Background technology

Refer to shown in Fig. 1, it is known that the packing box using plastic cement as material, to make there is stable knot between box body and lid 1 Conjunction state, the card article 2 of majority is convexly equipped with the inner side of lid 1, by the blocking of card article 2, makes to maintain stabilization between box body and lid 1 Bonding state.

For in industry, during by sheet via vacuum hot pressing formation, due between card article 2 and the raised box wall of its reason Segment difference height and without appropriate design, drop is obvious, consequently, it is possible to easily hinder between molded packing box and mould Depart from, in the case where completing the purpose of packing box and mould detached job, apply excessively or improperly external force, temperature can be caused not yet to drop The packing box being low enough so that under shape fixation degree, is deformed, and influences the quality of product.

Utility model content

Therefore, main purpose of the present utility model is the element improvement construction for providing a kind of packing box, and it can make packaging Box is easy to mould separation, avoids packing box from receiving improper force for the demoulding, ensure product according to this after autoclave moulding shaping Quality.

To reach above-mentioned purpose, the utility model uses following technical scheme：

A kind of element improvement construction of packing box, it includes：One sheet form base；One sheet ringwall, is located on the base portion The week side of boss；Most card bodies, are divided on the anchor ring of the ringwall；The card body has the whole body portion, extends outward from the anchor ring of the ringwall One protrudes distance, a sidepiece, is shaped in the side in the body portion, and from the elongated end end in the body portion with the inclination less than 90 degree Spend toward the anchor ring and tilt extension.

Further,

The card body is divided on the interior side ring surface of the ringwall.

The card body is divided on the outer side ring surface of the ringwall.

The gradient of the sidepiece is 75 degree, 45 degree, 30 degree or 15 degree.

The body portion is in strip.

The sidepiece is located at the side on the body minister direction of principal axis.

The card body has two sidepieces, is divided into the opposite both sides in the body portion.

The utility model has the advantages that：

Packing box of the present utility model element improvement construction, make between card article and box wall segment difference height, reduce gradually with The drop between adjacent position is reduced, so that being easily isolated between mould and packing box.

Fig. 2 is the stereogram of the preferred embodiment of the utility model one.

Fig. 3 is the top view of the preferred embodiment of the utility model one.

Fig. 4 is the sectional view of the preferred embodiment of the utility model one 4-4 faces line along Fig. 2.

Fig. 5 is the close-up schematic view of the preferred embodiment of the utility model one.

Embodiment

Refer to shown in Fig. 2 to Fig. 5, the element improvement structure of the packing box provided in the preferred embodiment of the utility model one 10 are made, is by taking the lid of packing box as an example, it includes the card body 40 of a base portion 20, a ringwall 30 and majority.

Base portion 20 is a tool appropriate size and rectangular flat plates.

Ringwall 30 is located in the week side of boss of base portion 20, is integrally formed with base portion 20.

Card body 40 is divided on the interior side ring surface 31 of ringwall 30 with spreading out, and generally along parallel to 20 bodies of base portion Direction extension certain length, and be shaped on ringwall 30.Card body 40 has the whole body portion 41, from the interior side ring surface of ringwall 30 31 extensions one outward protrude distance d, and are shaped in body portion 41 in the strip for being roughly parallel to base portion 20, a sidepiece 42 and grow On axle one end, and side ring surface 31 is extended on anchor ring with the gradient θ less than 90 degree inside at the elongated end end in itself portion 41.

Accordingly, when autoclave moulding is molded, body portion 41 causes what is formed between interior side ring surface 31 because of prominent distance d presence Segment difference, you can by sidepiece 42 with less gradient, reduce the height fall between adjacent regions, make separate with mould Stripping operation when, be avoided card body 40 and cause to hinder, make stripping operation smooth, and can be further assured that product Quality.

For further, in the space permissible range of interior side ring surface 31, the gradient of sidepiece 42 can be significantly reduced, Such as 75 degree, 45 degree, 30 degree or 15 degree angularly, but it is not limited with it, enables the drop between body portion 41 and inner ring surface 31 according to this Reduced gradually by sidepiece 42, make to be in more gentle construction, in favor of the progress of the demoulding.

In addition, can also make sidepiece quantity possessed by card body be respectively two, and make two side portions located at the opposite of body portion On both sides, quantitative variation still belongs to the utility model should be shielded.

The technical principle described above for being preferred embodiment of the present utility model and its being used, for the technology of this area It is any to be based on technical solutions of the utility model base in the case of without departing substantially from spirit and scope of the present utility model for personnel Equivalent transformation, simple replacement on plinth etc. are obvious to be changed, and is belonged within scope of protection of the utility model.
