The paper-made vessel that is used for flowing material

The present invention relates to be used for the paper-made vessel of flowing material.

The container quite heavy and that have the flowing material of oxidation or vaporization character of packing into should possess intensity, the antiseep of enough satisfaction, cuts off gas function or the like, and this is sought after.Be that the printing-ink of representative is a kind of high-viscosity material that contains volatile matter for example, wherein pigment, lake, dyestuff be stirred in the medium with typographic printing printing ink, gravure printing ink and planographic ink.Therefore, generally, general for example the employing by what sheet metals such as sheet tin and steel plate constituted comprises the container that body element, base member and cap element are formed, and makes iron flask with the method that sheet material rolls.Though this structure is guaranteed enough intensity, big weight container causes the traffic cost of container to improve.In addition, also there is following shortcoming in this container, because the sealing function of the attaching parts on the container is not enough, air penetration causes container contents oxidative polymerization to cause sclerosis.The shortcoming that also exists is in addition: because of such container is non-flammable, even the inclusion of container is adsorbed on the container after the use container, therefore, be difficult to remove the container after using, and the cost of removing container handling increases greatly.

Also adopt the container that does not have attaching parts by the method manufacturing of deep-draw sheet metal for this reason.But such container also has shortcoming, and promptly container is very heavy, and manufacturing cost is very high, and the container after using occupies big quantity space, and also is not easy to remove.

Having, is the oxidative polymerization printing-ink of representative with the offset printing ink again, polymeric pigment and easy reaction sclerosis adhesive agent flowing materials such as (particularly offset printing inks), and their viscosity is very high, is difficult to pure ground and takes out in container apace.For this reason usually re-uses these flowing materials after viscosity reduces, the method that viscosity reduces is in advance flowing material to be put in the stove together with container, and material has just taken out easily in the heating container, so container then.But till the complete heating of container contents, need for a long time with the stove heating.In addition, the material in the container is not easy even heating, and just there is following shortcoming in this, and is promptly overheated near the flowing material of thermal source, so produce undesirable peeling phenomenon.Therefore also require container need overcome this shortcoming and adopt best heating process.

Therefore the object of the invention provides the paper-made vessel that a kind of flowing material is used, and container has sufficiently high intensity and in light weight.

Another object of the present invention provides the paper-made vessel that a kind of flowing material is used.It has good anti-liquid, the blocking capability of gas etc. or sealing function.

A further object of the present invention provides the paper-made vessel that a kind of flowing material is used, and this container uses the back to remove easily and handles.

The present invention also has a purpose to provide the paper-made vessel that a kind of flowing material is used, and this container has improved the taking-up usefulness of container contents.

The present invention also has a purpose to provide a kind of inner cap that is applicable to above-mentioned paper-made vessel.

Will be clearer and more definite by the following detailed introduction of reference to other purposes of the present invention.

For achieving the above object, the present invention considers to adopt the container of mainly being made by paper wood.In this case, according to the viewpoint that keeps whole container, even when container contents is the material of quite heavy fluid, also adopt carboard.In addition, for seepage, oxidation or the vaporization that prevents material in the container, be provided with the coated film of blocking capability.Consider the cost reason, container is preferably by roll extrusion a piece of paper material and connect its end and constitute, and the paper wood with rolling forming connects base plate then.But because use carboard, thus only adopt this structure to produce step portion at connecting portion, because step portion causes the gap, so sealing effectiveness weakens.Therefore the present invention has adopted special construction to overcome the shortcoming that step portion produces.

The paper-made vessel of using according to flowing material provided by the invention comprises: cone body part (body part) and base member, base portion is interconnected to constitute by the roll extrusion sheet material and with the longitudinal end of sheet material, sheet material comprises and is applied to the thin layer (as coating) that has blocking capability on the carboard surface that thin layer is placed on the inside.Base member is made of the dish type sheet material, sheet material comprises and is applied to the lip-deep thin layer with blocking capability of carboard, the bottom of described base portion is bonded with each other in each film mode facing each other with the circumference of described base member and is connected, the first end that wherein said base portion constitutes connecting portion has around the carboard end face and arrives the continuous film of carboard outside face, the second end of connecting portion has step portion, this step portion is crooked from the endface position outside of first end, and extend along the outside face of first end, the interior film of the second end (promptly by any other thin layer) directly or indirectly connects the extension film of first end.

The concrete connotation of word " each thin layer is facing each other " is that thin layer directly or by any other thin layer is faced mutually.Be that thin layer remains in receptacle at least.

It is enough big to be used for carboard thickness of the present invention, makes problem can not take place under the normal transport condition even when flowing material is filled in the container.Usually cardboard is thick is 0.2mm to 1.0mm, and optimum value is 0.4mm to 0.7mm.Carboard requires to have good press strengthi and capacity to reprocess.

The blocking capability of qualification of the present invention means has one or more materials of cut-out that are higher than carboard such as the function or the resistance of liquid (as water), oil and flowing material.This will be according to the present invention container application and use occasion, concrete material and cut off function or resistance is determined greater than the degree of carboard.

For example, in the coated agent of printing ink etc., barrier functionality one of will be considered to have at least in water-proofness, grease proofness and the gas barrier capability.Most preferably blocking capability will comprise above-mentioned whole three kinds of performances.

When considering water-proofness in blocking capability, blocking capability refers to that water-proofness is higher than the carboard water-proofness.Specifically, water-proofness supposes that the pulling strengrth before the steep water is 100 after referring to that preferably test block is immersed in 25 ℃ water and reached 60 minutes, and Ci Shi strength rating should be 80 so.Optimum value is more than or equal to 90.

When in blocking capability, considering grease proofness, blocking capability refers to that grease proofness is greater than the carboard grease proofness, specifically, grease proofness preferably refer to test block be immersed in reached 720 hours in 50 ℃ the oil after, suppose that the pulling strengrth before the impregnation oils is 100, Ci Shi strength rating are 80 so, and optimum value is more than or equal to 90.

When considering gas barrier capability in blocking capability, blocking capability refers to the gas barrier capability of gas barrier capability greater than carboard.Specifically, gas barrier capability is meant that preferably the gaseous oxygen penetrablility under 25 ℃ reaches 24 hours 1 barometric pressures of 100 milliliters/sq m or still less, than the figure of merit is 24 hours 1 barometric pressures of 10 milliliters/sq m or still less, optimal value is 24 hours 1 barometric pressures of 1 milliliter/sq m or still less, measurement is to be undertaken by ASTM D3985.

Among the present invention, the thin layer formation method with above-mentioned blocking capability can adopt any means, can be single or multiple lift.Thin layer be fit to by plastics synthesizing multilayer film with constitute (the inorganic deposition layer of sedimentary deposit and following inner cap is identical, and it synthesizes and relates to specifying of inner cap) as monox or aluminium oxide inorganic deposition layer.The inorganic deposition layer is in the ambient atmosphere environment that is independent of variation such as temperature and humidity and have stable blocking capability.In addition, can adopt the combination multilayer film, this combined films is that organic barrier film and other synthetic resin layers are synthetic, the ethylene of organic barrier film and local saponification or polyvinylidene chloride.

The present invention is applicable to the container of printing-ink, and also as the container of various dissimilar flowing materials, these substance weights are big simultaneously, and requires not oxidized and vaporization.

For example, the present invention also can be applicable to the container of oxidative polymerization printing-ink, comprises the container for paint of blown stand oil, easily reacts the container of sclerosis adhesive agent, or the like.

The feature that is applicable to the inner cap of said vesse is at least on a surface, promptly forms inorganic deposition layer (promptly utilizing the vacuum film forming process to constitute inorganic thin film layer) on the one or both sides of plastic film.

Because fluid material container of the present invention is to be made by paper, and on the paper surface shaping coated film, so in light weight and be easy to transportation.In addition, because of the woof of container is a carboard, so the intensity height.If use the scraper by plastic production, when taking out container contents, container can break.

Container after the use, its built-in substance discharges, and the structure of container base portion is the taper that forms to downside, so container can get up by a ground of intussusception stacking.Under this form, container can be incinerated by burning installation, so container is easy to remove.

When making container,, utilize method such as heating ultrasonic vibration to obtain container, adopt the comparison that manufactures a product of the method for deep-draw relatively, cost of product is reduced by connecting vessel surface as the synthetic resin thin layer of coated film.

Under the base portion of container was passed through simply with the mode interconnective situation of a plurality of carboard sheet materials with overlap joint, cardboard was very thick, forms the gap at connecting portion between the inside face of base member outer circumferential edges and body element.Therefore, container contents goes out from clearance leakage, and container contents also is easy to oxidation because of air infiltrates by the gap seepage.But structure of the present invention is the outer end (the second end) in connecting bridge area, from the endface position of inner end, arrives the outside face of inner end (second end section) through crooked step portion.The result becomes the base portion inside face that connects the area and is similar between smooth so base portion inside face and the base member outward flange and do not constitute the gap.In addition, because the end face coverlay film of inner end, and the film of film connection outer end, so can obtain the satisfactory sealing effect.Any inclusion of container definitely can not spill.Also have, the smooth formation of connecting bridge, like this when the time with scraper taking-up container contents, the danger that connecting bridge does not break.

Referring now to the description of drawings embodiments of the invention.Fig. 1 to Fig. 7 shows the embodiment that applies the present invention to the printing-ink container.

Shown in Fig. 1 to 4, this container comprises the cone body element 1 that diameter increases from bottom to top gradually, tray-shaped bottom element 2, seal stock 3 (inner cap) and be installed in cap member 4 on the seal stock 3.Folding sweep 10 in the lower end of base portion 1 constitutes, its upper end forms outer flanging part 11.Constitute the closure wall portion 20 of extending downwards, so that carry out bending from the periphery of base member 2.Closed wall portion 20 is connected and cooperates and adhere to curve 10.Seal stock 3 has the barrier gas ability, and it is connecting flanging part 11.Printing-ink is filled in the container.After printing-ink is filled into container,, form container as gas replacement by irritating inert gas such as nitrogen and seal stock 3 being connected flanging parts 11.

Among the present invention at least body element 1 and base member 2 respectively by mainly being that the synthetic sheet material 8 that paper wood constitutes is made, the coated film of coated with satisfied fuel resistance, water-proofness and barrier gas ability separately on the carboard A surface as shown in Figure 5, the thickness of carboard A is 0.2mm or bigger, optimum value is 0.4mm or bigger, so that container has enough intensity.Coated film B is that (promptly the structure of Xing Chenging is that deposition is the inoranic membrane B22 of representative with the monox on matrix resin layers B11 to multiple-structure, resin bed is a polyethylene terephthalate for example, and uses the oil resistant film B44 of adsorbed layer B33 lamination such as linear low density polyethylene in the above).Cap member is preferably made by above-mentioned synthetic sheet material by metal or plastic production.If the formation of cap member 4 former upper surfaces is provided with male member in addition, the following concavity partial engagement of it and end element 2, this accumulation for container is very easily, and polyethylene film is coated in the outside face of synthetic sheet material 6, so that rust protection and improve water resistance.

Cut 6 one-tenth similar fan-shaped formation base portions 1 of above-mentioned synthetic sheet material, roll extrusion sheet material 6 circularizes, and B is deposited on inner face with the coated film, connects each coated film B at the folding two ends of synthetic sheet material at longitudinal direction.As shown in Figure 2, the inside face of connecting bridge 7 does not have step portion, and it has the curved surface roughly the same with body inner surface 8, and inside face 8 does not comprise connecting bridge 7.Adopt the method for method of heating or ultrasonic vibration method or the two combination to utilize partial melting or semi-molten resin that the coated symphysis is connect.

As shown in Figure 3, base member 2 is matched with body element 1 so that the outside face of closure wall part 20 abuts the inside face 8 of main body.Coated film B, promptly these mating surfacess B interconnects by above-mentioned process.The synthetic resin rete B of folding sweep 10 in the inside face of closure wall part 20 connects, and the knurled portion of joint annular knurl 12.Therefore, bottom 2 and body element 1 whole formation.

The coated film of outer bead portion 11 outside, seal stock 3 connects coated film B.

Connecting bridge 7 above-mentioned will be described in detail in detail below, be placed in the inside at the first end 6A of connecting bridge 7 synthetic sheet materials 6 longitudinal directions, the second end 6B of synthetic sheet material 6 longitudinal directions overlaps the outside of first end 6A.The coated film B of the second end 6B does not arrive carboard end face A ¹The coated film B of first end 6A extends, and has B so that form continuously ²Outer folding extension coated film B ¹, B ²The end face A of the topped carboard of part ²The outer folding coated film B that extends ¹Constitute the vertical direction belt shape on the carboard A outside face.

Vertically radially outstanding, the jag by the second end 6B extends at circumferencial direction the second end 6B then together with the crooked end difference 60 in coated film B footpath.The B of the carboard end surfaces of topped first end 6A ²Part is with the coated film B of folded state at crooked step portion inner face connection the second end 6B.Outer folded extension B ¹B is interconnected with one another by crooked end difference 60 with folded state with the second end 6B coated film.

Being constructed as follows of above-mentioned connecting bridge 7: shown in Fig. 6 A and 6B, synthetic sheet material 6 is cut into size L ¹, L ¹Length suitably long slightly than constituting the required size L of container body part, then shown in Fig. 6 A and 7A, side at vertical first end 6A, carboard A cutting is reached certain limit, till the back side that promptly reaches coated film B reveals or tissue layers still retains, to form coating portion 61 counter-rotating, that extend.In addition, thin layer portion 61 is towards the bending of the sheet material back side, and adhesive B (when the outside at synthetic sheet material 6 forms as poly film, can not adopted in the back side that utilizes adhesive B3 to connect carboard A ₃), so form the outer folding coated film B that extends ₁, shown in Fig. 6 A and 7B.Should note inclined cut part 62 in vertically first end 6A place formation, and the turning is near the outer folding coated film B that extends ₁, folding sweep 10 in therefore being easy to form.

Subsequently, as shown in Figure 8, synthetic sheet material 6 rotates around conical mandrel 9, therefore the second end 6B is repeatedly on first end 6A, in this case, from the outside synthetic sheet material 6 being pressed tap web axle 9C derby 9A by derby 9A promptly is a heat block, high-frequency vibration piece or ultrasonic vibration piece).Near while briquetting 9B presses synthetic sheet material 6 immediately first end 6A outside.The inner face of the second end 6B tightly contacts conical mandrel 9 as a result, and the smooth inner face that cooperates with first end 6A has just formed like this.Simultaneously, crooked step portion 60 is made of the side of heat block 9B, and is heated or vibrates by attaching parts.Therefore coated film B and the outer folding extension coated film B of crooked end difference 60 from extending here ¹Connect together each other.

It should be noted that according to circumstances crooked end difference 60 can form on synthetic sheet material 6 by methods such as pressing molds in advance.

Because body element 1 of the present invention at least and base member 2 are by synthetic material, be paper main the composition, constitutes, so the printing-ink container of embodiments of the invention is light-duty.In addition because of paper thickness is big, so the vessel strength height.Therefore when the printing-ink with certain viscosity took out with scraper, even scraper abuts nearly vessel surface, container also was difficult for breaking.

Therefore the vessel surface that contacts with printing-ink 5 is by having the good gas blocking capability, the coated film B of oil resistant China ink characteristic and fire resistance characteristic constitutes, so do not exist solution to leak out, the solid matter (possibility that volatilization situation that fluent leaks out or outside air enter situations such as container.Base portion 1 forms under first end 6A and the overlapping and interconnective situation of the second end 6B.But because the step portion that paper thickness causes does not appear at container body part inside face, like this, because the second end 6B has the crooked step portion 60 that improves on the lateral surface direction at first end 6A endface position place, so first end 6A and the second end 6B constitute continuously with the smooth curved form for curvature.

Therefore, the gap between the outer circumferential edges of base member 2 and body element 1 inside face can not form at connecting bridge, so do not have flowing material or liquid to spill from base member 2.In addition, the end surface A of first end 6A ²Last formation coated film B ², the coated film B on the crooked end difference inside face of the second end 6B be melted and with coated film B ²Connect.Therefore kept good sealing effectiveness, also do not had flowing material or liquid to leak from connecting bridge.Also have, the connecting portion of the outer bead portion 11 at container upper end portion place on the sealing surfaces between seal stock 3 and the outer bead portion 11, step portion can not occur.Prevent hermetic unit infiltration outside air for this reason.After material is packed into container in the container, unreactable gas is charged in the container, container seals tightly with the seal stock 3 with gas barrier function, prevents that printing-ink from solidifying.

When printing-ink is discharged and container when having fallen sky from container, because the diameter of the base portion 1 from container bottom to the top increases, so the stacking of form in groups that container can folded gets up.Do not need the storage area like this.In addition since body element 1 and base member 2 by mainly being that synthetic material by paper constitutes is made, so do not need to adopt for hazardous material be coated with technology specially clearly.Also have because container can be used the method ashing identical with general waste material, the volume of container is easy to reduce, and container also is easy to remove and handles.

In addition, the fluid material container of the embodiment of the invention can adopt the electric furnace heating, this method can not be used for traditional can or have with aluminium foil as ammonia block the layer container, improved the function of taking out high-viscosity material from container, and significantly reduced time of heat.

Below the most preferred embodiment of detailed introduction operation and seal receptacle 3, promptly introduce the inner cap of the container of printing-ink in the foregoing description.

Generally speaking, the inner cap that adopts tradition to use does not allow air from the printing-ink upper surface interior.
