Description

Method of manufacture of box particularly intended for packaging and/or presentation of objects and box particularly obtained in accordance with such method

The present invention is relevant with the manufacture method that is specifically designed to packing and the box of displaying articles.

The present invention is especially relevant with a kind of like this manufacture method of box, form the side of this box and at least base panel with and outward appearance it seems that the ornament materials of quality top grade is as leather or fabric parcel.

In addition, the present invention is with relevant with displaying box by the luxury packing of the specific preparation of this method.

External packing exterior material, the box of material as leather, fabric or outer appearnce, its standard fabrication methods is to form the housing identical with finished product box shape by thermoplastic injection technique, then at this housing outer wrapping ornament materials.

Be readily appreciated that, on housing, wrap up ornament materials, must complete with the most accurate method, especially, at the connecting portion of ornament materials, to make box seem that workmanship is meticulous, have good quality.

The desired hand work of this method, can only make titular skilled worker do, thereby makes this box expensive.

Also have, this method can not be carried out automation, because be difficult to housing to carry out accurate operation, to wrap ornament materials.This need to adopt can be at the machine of space specific direction location.Larger difficulty is also that ornament materials is all tensile, but they can not be overlapping in abutting connection with position again can not be separated.

In addition, the manufacture method of known jewel box from 644, No. 057 patents of Switzerland, the method comprises, first the materials and parts of the epidermis homogeneous as ornament materials is placed in injection model, with core rod, materials and parts is clamped to fit like a glove with model interior shape.Then in model, inject the liquid material of High Temperature High Pressure, it makes the materials and parts of uniform surface in the inner flattening of model.

Although the practicable automation of this method and substantially can reduce the manufacturing cost of luxury box, needs to manufacture very expensive injection model and supplemental core, in advance ornament materials is placed on to the ideal position in model before injecting hot liquid material.There is no such location, due to high pressure will generating material overflow.

Also have, during injection, the high temperature of hot liquid material can cause that ornament materials expands, and even makes its quality variation.The ornament materials that therefore this method restriction is selected can only be very special compatible material.

Therefore the object of the invention is to overcome these difficulties, the method for the box of manufacturing packing and displaying articles is provided, can greatly reduce production costs on the one hand, in the time of can guaranteeing to manufacture box on the other hand, substandard products be minimum, in other words, meet special quality standard.

For this reason, target of the present invention is to provide the manufacture method of the box having good quality that is specifically designed to packing and/or displaying articles, this box comprises the plate that forms respectively side and at least one bottom surface, the ornament materials such as at least some plate outsourcing leathers or fabric, is characterized in that the method is comprised of following steps:

(a) provide for forming the parts that are processed at least partly bar shaped or plate shape of box board, these parts have at least one side to process or half machining state;

(b) in model, arrange and assemble these parts, to construct and be pre-formed a box with the whole three-dimensional structure of certain volume;

(c) in preformed box, inject thickness or half thick liquid nano, the very little resin that do not expand or expand, this resin is used for forming the material of assembly unit;

(d) thus model is also done to spreading action to box so that resin is at least coated in the connecting portion of assembly unit;

(e) make resin solidification, especially by polymerization, it is solidified;

(f) from model, take out the box of making.

Be appreciated that, originally the pre-assy parts that provide can be to process or semi-finished, as decorated in advance or veneer, can adopt the method for automatic operation, extensive and two-forty ground produces these bar shapeds or plate shape parts, because these parts can be decorated in advance, through processing or half processing, then they are assembled into box, thereby can manufacture these parts with different materials, even use the material of material different colours of the same race, or the material that differs greatly of appearance.Can obtain the box of " luxurious " standard like this, comprise the box that those outward appearances are peculiar, meet especially the person's of hunting for novelty requirement.Also these parts of decorating in advance can be understood and rigidity or semirigid structure can be comprised, thereby when they are inserted to model, the shape that can really formalize by their pre-assy body formation box, otherwise by the very accurate thereby expensive model of needs.

In addition, inject any type of minimum resin that do not expand or expand, can eliminate all mechanical streess that act on pre-assy parts, thereby can between these prepackage accessories, adjust well, and the limit that can not make them join is separated.The finally rotation by model is coated in cassette interior by resin, guarantees that resin is coated on box inside face ideally, then solidifies and awards box with very high intensity.Due to the means as assembling with this resin, can make the thickness of assembly unit very little.

Also have, according to another feature, the resin providing in the step of mentioning in the above (c) is applicable to forming the rigid mechanism of box after polymerization.

Should particularly point out, in one embodiment, in step (a), this method comprises especially:

(g) parts of decorating in advance that formed by bar or plate comprise: strip piece has foldable semi-rigid reinforcement at least partly, and panel-like member has at least part of rigidity or semi-rigid reinforcement.

According to another embodiment, in step (g), this method also comprises especially:

(h) from the material wheel of a side, provide continuous reinforcement material strip, from the material wheel of opposite side, provide decoration material material strip, the width of every ornament materials is at least large than the width of corresponding reinforcement material strip, so that the side of decoration material material strip can be piled up;

(i) in the same direction reinforcement material strip and decoration material material strip are piled up;

(j) from material wheel without interruption each, and decorate progressively reinforcement material strip by decoration material material strip;

(k) in the middle of, add adhesives, overlapping edge break is returned;

(l) then the material strip of having decorated in advance is like this cut into the section of certain length.

Another target of the present invention is to provide the box of packing and displaying articles, this box comprises and forms respectively its side and the plate of bottom surface at least, at least some plates process or half finished appearance, the feature of this box is that the pre-assy parts of being produced by automatic mode at least partly form, utilize the minimum resin that do not expand or expand to be at least coated in the connecting portion of these components interior, these parts itself are interconnected, to form box three-dimensional or three dimensional form, these resins become the assembling means of these parts.

Below reading, according to the detailed description of doing with reference to accompanying drawing, can understand better the present invention, this is only casehistory certainly.

---Fig. 3 is the transparent view of each pre-decorative element number of assembling steps in model;

---Fig. 3 a and 3b are respectively along the cross sectional drawing of Fig. 3 center line IIIa-IIIa and line IIIb-IIIb;

---Fig. 4 is by the resin injection transparent view of moulding box in advance;

---Fig. 5 is the transparent view that scatters resin in box;

---Fig. 6 is the cross section of half box of the present invention of preparing of the manufacture method that shows according to above-mentioned each figure.

With reference to figure 6, first describe according to packing of the present invention and displaying case.

Box comprises and forms respectively at least plate 2 of bottom surface 4 and side 6, shows a veneer here.In this example, plate 2 use ornament materials 8 be it seems the natural or synthetic material parcel of quality top grade as leather or fabric or outward appearance.This plate 2 is the plank of veneer also, or skin covers with paint, lacquer, colour wash, etc., and makes box look that processing is meticulous, and this does not depart from aim of the present invention.

In description below, will understand that, this plate comprises each parts EU1, EU2 and EU3, and they are made and are adapted at carrying out preassembled standardized component before last combination.Parts EU3 forms supporting mechanism, determines the chamber C that holds institute's displaying articles.Lid does not show in the drawings, can prepare easily according to method of the present invention, can match with box 1, at least cover a part of parts EU2 and EU3.

Parts EU1 comprises reinforcement 10, and parts EU2 and EU3 comprise similar or identical reinforcement 12.Reinforcement 10 consists of rigidity or semi-rigid material, and reinforcement 12 is preferably by semi-rigid material, is especially applicable to folding material and forms.Reinforcement 10 and 12 is preferably made by carboard.

As shown in Figure 6, ornament materials 8 on each Self-decorating of parts EU1 to EU3, before overall package EU1 to EU3, can decorate reinforcement 10 and 12 in advance with ornament materials 8.Can be with the such global facility of automation mechanized operation manufacture, then with the resin R not expanding or expand the very little thing of mediating, parts EU1 to EU3 is combined, to major general's resin, be coated in the connecting portion of these parts.Therefore by resin R, make these parts EU1 to EU3 be fitted to each other into the box of three-dimensional or three-dimensional form, simple to operate, cost is little, is therefore very easy to the production manufacture by standard.

Should notice that parts EU1 to EU3 interconnects by overlapping edge 14.The overlapping limit 14 that forms the global facility EU2 of box 1 side 6 is adhered on corresponding reinforcement 12, and the limit 14 of bottom surface 4 keeps free state and along the side 6 with combination, parallel direction rises substantially.Therefore the edge separately 14 of bottom surface 4 as shown and side 6 is mutually close to and is set up a bonding land, forms sealing mechanism to avoid resin R to flow to the outside of box 1.On the inner overlapping limit mutually flattening 14 of box 1, form re-entrant angle seam.Thereby can see that resin R does not resemble the adhesives of standard and be coated between both sides 14, but resin R is coated on two limits 14 exposed and that directly contact flattens mutually simultaneously, thereby limit 14 is clipped in to one side, be that brace panel 12 another sides are between resin R.Resin R is at least coated on the part inside face of EU1 and EU2.In the example of Fig. 6, resin R, as polyurethane-type resin, is coated on the whole inside face of bottom surface 4 and side 6 substantially equably, to form the layer that is uniformly distributed that makes box rigidization.The effect of resin R, except the assembling means as between different parts EU1 to EU3, also forms rigid mechanism.Therefore easily understand, parts EU1 and EU2 can by thin slice for example veneer form.

As everyone knows, can make resin R only be coated in the connecting portion of overlapping edge 14, but with leather, fabric or analogue decorative element in the situation that, seem always to wish to select reinforcement, especially the reinforcement of side 6, soft as much as possible, therefore also wish resin to be coated in the inside of whole box 1 to form rigid mechanism.

With reference now to Fig. 1 a to 1e, describe the manufacturing step of parts EU2, these parts form box side 6 according to the present invention.

According to Fig. 1 a, there are two material wheels 20 and 22, continuous exposed 24 that reinforcement 12 is provided, another provides the bar 26 of ornament materials 8, when progressively decorate reinforcement 12 with ornament materials 8 from material wheel 20 and 22 is pulled out, easily understand, only otherwise interrupt, the material that this program can proceed on will material wheel 20 and 22 is always finished.Adopt large capacity roller, can carry out large batch of continuous flow procedure.

It should be noted that especially, in the method, the material strip 24 of reinforcement 12 and the material strip 26 of ornament materials 8 stack in the same direction, then between them, add continuously adhesives 28.Utilize this adhesives being added in one or both material strips for gluing equipment (not shown) of standard, for example, in the material strip 26 of ornament materials.One or both material strips 24 and 26 also can be carried out pre-gluing.

Also have, the material strip 26 of ornament materials 8 is provided by this way, make its width L at least large than the width of the material strip of reinforcement 12 24 1, to can make the material strip 26 of ornament materials form overlapping limit 14.

Then as shown in Figure 1 b, overlapping limit 14 is gone back on reinforcement 12 by arrow 13 directions, centre scribbles adhesives 28.

Then as shown in Fig. 1 c, with blade 15, the material strip of just having decorated is in advance cut into each section of S by selected length L s.

With reference to figure 1d, in step below, section S is prebended under the clamping of fixture 30 to suitable form.

As shown in Fig. 1 e, Manufactured parts EU2, is to make moulding in advance and two free ends of pre-upholstery border dock to form the framework of box 1 profile.Therefore by the parts EU2 of bar 24 and 26 preparations, formed the side 6 of box 1, it comprises can folding reinforcement 12 be favourable.Also must illustrate, reinforcement 12 can consist of the composite material that comprises semi-rigid part and special flexible portion, to form four jiaos of box 1.

Below with reference to Fig. 2 a to 2c, the manufacturing step of illustrated parts EU1, according to the bottom surface 4 of box 1 shown in EU1 pie graph 6 of the present invention.

According to Fig. 2 a, utilize instrument 40 slave plate 42 punching presses to cut the plate shape material 44 of rigidity or semi-rigid reinforcement 10, plate 42 do not cut half be also shown in figure.Then according to the first embodiment shown in Fig. 2 b, utilize the adhesives 48 being clipped in the middle, the plate shape material 44 cutting is bonded on the plate shape material 46 of ornament materials 8.Then utilize stamping tool 50 to cut the plate shape material 52 of ornament materials 8, reserve as shown in Figure 2 c overlapping limit 14.

According to another embodiment, cut plate shape material 52 (Fig. 2 b) of ornament materials 8, then the plate shape material 44 of the rigidity first cutting or semi-rigid reinforcement 10 is adhered on the plate shape material 52 of the ornament materials 8 cutting.

Thereby obtain plate shape material P plate shape material 52 and 44 is overlapping and that be bonded together, such composite panel P is decorated separately in advance.Plate shape material P forms global facility EU1, with it, forms the coating member (not shown) of the end 4 or box 1.

From Fig. 1 a to 1e and Fig. 2 a to 2e, it seems, by the bar material 24,25 processing and/or plate shape material 42,46, prepare separately such pre-decorative element EU1 and EU2, these operations of permission are carried out substantially in the plane, that is to say and be actually two-dimensional operation, this just makes to manufacture these special production machines and becomes not too complicated.

Therefore easily understand, in above-mentioned step, can supply for forming the standardized component processing at least partly of box 1 plate, at least one side of these parts has processed or half processing.

Consult Fig. 3 below, can see in model M, between different parts EU1 and EU2, adjust the step with assembled in advance.First, the first step be by one section in advance upholstery border S put component parts EU2 in middle model M, to be pre-formed each limit 6 of box 1.In order doing like this, the two ends of S section to be close to and to be docking together, to form article one list seam.

Secondly, in the closed shape forming like this at section S, put into plate shape material P and adjust, to form the end 4 of box 1.When the plate shape material P section of putting into S, should allow the overlapping edge of this plate 14 to enter into the inside that is pre-formed box, in other words the inside face of an overlay segment S part.

It should be noted that the surface of selecting reinforcement 10 with such method, make it the surface that joins with section S basic identical.

In Fig. 3, can also see, in model M, only place one section of S, so that the respective regions on one side 6 of box 1 only forms single seam 51.Should be the back side that here be placed on box, in other words, load onto hinge sewing on, can be not in sight, and suitably cover last layer thing, also can't see.

Be readily appreciated that, can arrange several sections of S, for example 4 sections rather than one section.

The next step of following as seen in Fig. 4, by the resin injection of thickness or half thick liquid form by EU1 and the preformed box of EU2 two parts.Resin R is placed in the very simple container 60 representing.

Then, as shown in Figure 5, make model and following box motion, be called and disperse motion, by arrow, N represents.Such motion is to make resin dispersion, to be at least coated in EU1 that plate shape material P and section S form respectively and the connecting bridge of EU2 parts, is preferably distributed in the main portion that is pre-formed box 1 inside face.

Therefore model M is installed on plate 62, suitable motion is provided this plate so that resin flows to the place that needs it.In this operation, preferably at ambient temperature, allow resin solidification and polymerization.Should note, resin R is being injected after box 1, between represented each step of Figure 4 and 5, can form respectively at plate shape material P and section S the end 4 and each side 6 of box, in the closed shape forming like this, at least put into the global facility EU3 that an additional trim board in advance forms, to form the inside of box, for example, as the support of wanting displaying articles.The flat board of making formation global facility EU3 is identical with the flat board of making formation bottom 4, but with folding step (not shown).

Resin R can take out box 1 after solidifying from model M.Box has just completed, and needn't just process again and can sell.

In the description of just now carrying out, with numeral 1, represent box, box is target of the present invention, according to method of the present invention, manufactures.

Like this, " box " will be understood to have certain thing of volume, no matter it is opening or sealing, whether intends to receive article, and it all has certain function.The mode of such box available standards is placed article, and box also can be used as support seat, the such article of present upper ornaments.
