Sleeve 10B is being assembled under glass state of main body 10A, sleeve 10B can contact with outwards outstanding horizontal ribs 13, also can separate.Under discontiguous situation, insulated space A is big, air convection current up and down in the insulated space A, and heat is easy to diffusion.Therefore, after injecting hot water, when taking metastomium 11 with hand, though the sidewall 15 of sleeve 10B what can be crooked to the inside, and compare with the situation that rib 13 has contacted with hand hold vessel 10 front sleeve 10B, the surface temperature of sidewall 15 is low, is easy to take.

The heat-insulated container of Fig. 2 A, Fig. 2 B, Fig. 2 C display application embodiments of the invention 2.

During the user take to inject behind the hot water with hand or the sea after the micro-wave oven heating is bowl-shape container, normally use the first half of the finger of two hands from the left and right sides, both sides supporting container metastomium.In the heat-insulated container of Fig. 2 A, Fig. 2 B, Fig. 2 C, realized the effect of heat insulation and the stability of the part of user's finger contacts.That is, in the heat-insulated container 10 of Fig. 2 A, Fig. 2 B, Fig. 2 C, heat insulating member 17 is reeled be bonded in glass top of the metastomium of main body 10A 11, installing sleeve 10B from it in advance.

Heat insulating member 17 can use vertically alternately arranging raised line and recessed 's paperboard sheet or being processed to form the paperboard sheet of the Rack of concaveconvex shape through embossing through waveform processing the middle insides that resembles corrugated sheet.

When heat insulating member 17 is located at glass main body 10A and sleeve 10B, can realize the raising and the stability of the thermal insulation on the metastomium top that insulated space A narrows down.Therefore, after the heating modulation of injecting hot water or being undertaken, can take heat-insulated container 10 with hand relievedly by micro-wave oven.The heat-insulated container 10 of Fig. 2 A, Fig. 2 B, Fig. 2 C is injected at hot water under the situation at top of heat-insulated container, and is especially effective.

In addition, in order to prevent to be contained in coming off of sleeve 10B on glass main body 10A that the interior week and the cup main body 10A of inside curled portion 16 is bonding, or the interior outside of heat insulating member 17 is bonding with cup main body 10A and sleeve 10B respectively.

Fig. 3 A, Fig. 3 B are the ground plans of the cup main body 10A that uses of the heat-insulated container of Figure 1A, Figure 1B, Fig. 1 C or Fig. 2 A, Fig. 2 B, Fig. 2 C.

As mentioned above, shown in Fig. 3 A, Fig. 3 B, on cup main body 10A, be provided with around the horizontal ribs 13 or 13 ' in the ring week of metastomium 11 at the assigned position of metastomium 11.As shown in Figure 3A, horizontal ribs 13,13 ' can be provided with around metastomium 11 continuously.Shown in Fig. 3 B, also can utilize otch 19 that horizontal ribs 13,13 ' intermittently is provided with around metastomium 11.

In the occasion of the heat-insulated container 10 of Figure 1A, Figure 1B, Fig. 1 C, if the radical of horizontal ribs 13 is certain, then under interrupted situation, compare with the situation that continuous rib 13 is set around rib 13, poor slightly aspect the sidewall 15 that prevents sleeve 10B crooked.But insulated space enlarges, and insulated space is communicated with up and down, and the moving of hot air that add in the insulated space integral body carried out easily.Therefore, temperature rises evenly, and the result can obtain the effect that thermal insulation improves.Under the interrupted situation of rib 13, a root 13 is with respect to 4～8 parts that preferably are divided in full week of metastomium 11.Notch 19 is preferably below 30% with respect to the ratio of the full Zhou Suozhan of metastomium 11.

Shown line afterbody 18 among Fig. 3 A, Fig. 3 B.Inwardly curled portion 16 is used to imbed the space (opening of the lower end side of insulated space A) of line afterbody 18.Therefore, needn't worry that rubbish enters or water immerses from line afterbody 18 from line afterbody 18, can provide the heat-insulated container of health.

According to the structure of above heat-insulated container 10, use and the existing identical paperboard base material of heat-insulated container made of paper, the big very big bowl type heat-insulated container made of paper of the peristome external diameter with 120～200mm scope can be provided.Under situation about filling with, internal volume can be set in the scope of 600～1500cc.

Though being used for the paperboard base material internal volume of the shaping of heat-insulated container 10 increases but still can use and the heavy base material in roughly the same level ground that uses at present.That is, the shaping of cup main body 10A can use the level ground to weigh 190～450g/m ²The cup body paper.And the shaping of sleeve 10B can use the level ground to weigh 230～450g/m ²Paperboard such as card (カ-De) class, coated paper (コ-ト ボ-Le) class.When heavily discontented this limit in the level ground of the body paper of sleeve 10B, the rigidity of sleeve 10B will reduce, and high amount of deflection just might be excessive and can not get the thermal insulation of needs when hot.When the level ground of the body paper of sleeve 10B heavily surpasses above-mentioned limit, though the rigidity height, inwardly the processing difficulty of curled portion 16 will worsen, and material cost also can improve, and is therefore undesirable.

The base material of sleeve 10B can carry out resin coating or resin impregnation processing etc.In this case, can improve heat-insulated container 10 single-piece rigidity, resistance against compression and withstand voltage routed property etc., externally applied forces when making heat-insulated container 10 opposing logistics and protect content.

Usually, scope extruding, the coating with 20～80 μ m is formed with polyolefin type resin layers such as ldpe resin, medium density polyethylene resin, high-density polyethylene resin, wire ldpe resin on the cup body paper inner face.Polyolefin type resin layer helps preventing that content from soaking into, improving the degree of protection of content to paperboard (the base material of cup main body 10A), also help improving bottom, curled portion, trunk paste section the cup formability, the heat seal of the top curled portion of utilizing cover piece (not shown) is carried out sealing property good.

In above heat-insulated container 10, sidewall (periphery wall) is gone up no concave-convex, and the inside curled portion 16 of sleeve 10B forms suitable fillet in the bottom of container, so, but aesthetic appearance.

The surface of the sidewall of heat-insulated container 10 is smooth, to the printing degree of freedom height of sleeve 10B.Known printings such as not only offset printing, intaglio, aniline printing, and the processing of printings such as various glazings, gold stamping, embossed back also can freely be carried out on sleeve 10B.Therefore, in conjunction with described good aesthetic appearance, can bring into play good decoration effect.

By at the side wall surface of sleeve 10B or glazing layer such as OP varnish inwardly is set on the surface of curled portion 16, can make these faces be difficult for drenching and be difficult for by dirty dirty.

What usually, must take into full account when the plastic cover of hot water contacting container inner face or plastic layer is to remain in the separating out of monomer plastics in, the heavy metal class that be used for polymerization catalyst, other additives etc. easily, and produce the problem of food pollution thus.Be no more than in their amount of separating out that to constitute container under the prerequisite of a reference value of food hygiene law regulation be certain, but, even the denier that this numerical value is following, for example resemble the dihydric phenol A that separates out from the polycarbonate resin that is used for the edible tableware of feeding bottle or school more or criticize the use of the resin that might upset biological endocrine hormone (exogen incretion harass chemical substance) class, consider preferably to avoid from the prevention principle by the quilts such as styrene oligomer that the polystyrene foamed container is separated out.

In above-mentioned heat-insulated container 10, owing to be from these dangerous little polyolefin resins, further select natural resin and be used for the coating of inner face, so have relieved sense.

Below just the manufacture method of the heat-insulated container 10 of Figure 1A, Figure 1B, Fig. 1 C or Fig. 2 A, Fig. 2 B, Fig. 2 C describe.

At first, utilize the metastomium 11 of dixie cup shaping machine,, form bottom 12 with the bottom of base plate coiling shutoff metastomium 11 by fan-shaped blank shaping truncated cone shape.Outside top curled portion 14 is shaped in the upper end of metastomium 11.Then, the assigned position at metastomium 11 outwards is shaped or inwardly outstanding horizontal ribs 13,13 ' manufacturing cup main body 10A.

To the job operation of the outstanding rib 13 of foreign side for shaping machine, can online processing or off line processing.That is, the die cavity with the cup main body 10A after being shaped embeds the metal pattern of the part cutting grooving shape that will be equivalent to horizontal ribs 13 in advance makes a glass main body 10A rotation.Partly using expander (expander) will rotate the roller brute force from the inboard of cup main body 10A to above-mentioned groove shape under this state pushes.Thereby form outstanding laterally rib 13.

In this case, as long as push the rotation roller, just can obtain the rib 13 of continued circling as shown in Figure 3A along the complete cycle of cup main body 10A.Push to cup main body 10A if will rotate roller discontinuously, can form shown in Fig. 3 B interruption around rib 13.

In above manufacturing process, need from the die cavity of metal pattern cup main body 10A be extracted in processing rib 13 backs.In Figure 1A, Figure 1B, Fig. 1 C or Fig. 2 A, Fig. 2 B, Fig. 2 C, under the slow situation of the inclined-plane of the summit of horizontal ribs 13 upside, can in die cavity, easily extract a glass main body 10A than the inclined-plane formation of downside.The formation of rib 13 also can be adopted the stretch process of using feature die.

The rib 13 ' of the heat-insulated container 10 among Fig. 2 A, Fig. 2 B, Fig. 2 C forms by following order.Cup main body 10A after being shaped is embedded the periphery of the axle of the part cutting grooving shape that will be equivalent to horizontal ribs 13 ' in advance.A glass main body 10A is rotated with axle, push from cup lateral above-mentioned groove shape part brute force simultaneously.Thereby can form outstanding to the inside rib 13 '.Form the sleeve 10B of truncated cone shape by the blank of fan-shaped, form inside curled portion 16 in its underpart.In position that both are in contact with one another with this sleeve 10B and the bonding assembling of cup main body 10A after being shaped then can obtain heat-insulated container 10.The heat-insulated container of the present invention 10 overlappable users of offering that finish.

Above sleeve 10B is contained in the periphery of above cup main body 10A, with the contact site of the bonding bottom 12 of acrylic compounds latex binder, make have Fig. 4 A, the side shown in Fig. 4 B and embodiment sample A, the sample B of section.Prepared to omit horizontal ribs 13,13 ' Comparative examples A in addition ', B ', embodiment sample A and comparative sample A ' and embodiment sample B and comparative sample B ' are carried out following comparison respectively.

95 ℃ hot water are annotated 500cc to sample A, A ' respectively, inject 660cc, take the epimere of the metastomium of each sample after 3 minutes with two hands from both sides, compare surface temperature sensuously to sample B, B '.Its result as can be known, embodiment sample A, B than comparative sample A ', B ' distortion little, thermal insulation is good, takes easily.Comparative sample has been felt temperature consumingly as arresting metastomium tightly.

According to above heat-insulated container 10, be shaped as and use peristome external diameter that the paperboard base material with the roughly the same specification of prior art is shaped shape greater than the big very big bowl type of height, though inner capacities has increased when cup-shaped than existing, even also can reduce distortion of vessel but fill with hot water, can have good thermal insulation.

Therefore, carry out hot water modulation or micro-wave oven heating modulation with each container, can be used as the wide-mouth tableware that replaces big very big bowl or alms bowl and provide various food, happiness, have dinner simply to the place of having dinner, can be to ordinary consumer, especially advanced age, person or health obstacle person and children etc. provided accessible commodity.

The metastomium outer wall no concave-convex of heat-insulated container 10 has the degree of freedom of good surface appearance and printing, in conjunction with the printing effect to the cover piece of wide-mouth, can be implemented in the good promotion effect of storefront.

Can not separate out the suspicious material such as environmental hormone that see the polystyrene foamed that existing heat-insulated container uses from the polyolefin type resin layer of the inner face of heat-insulated container 10.Inwardly the line afterbody 8 of curled portion 16 in the bottom surface adds the gap of burying glass main body 10A and sleeve 10B, can prevent that rubbish or foreign matter from immersing metastomium or absorbing liquid from the paperboard end face, prevents dirty from the bottom.Therefore can improve safety, the reliability of relevant health.

Because even the inner capacities increase also can use the paperboard base material roughly the same with the prior art specification, so can suppress the rising of cost at material cost and manufacture view, reasonably financial cost provides heat-insulated container.

Heat-insulated container 10 uses the back discarded as paper products, and easy again capacity reducing so waste treatment is good, and also can reclaim, so can help reducing environmental pressure.

Fig. 5 A, Fig. 5 B, Fig. 5 C show the heat-insulated container of the embodiment of the invention 3, and Fig. 5 A, Fig. 5 B, Fig. 5 C line of centers right side separately shows the side, and the left side shows section.

The heat-insulated container 20 of Fig. 5 A, Fig. 5 B, Fig. 5 C is with the sleeve 20A made of paper of rounding frustum shape and dixie cup main body 20B combination and constitute.Cup main body 20B has barrel-contoured metastomium 31 and reels and seal the bottom 32 of the bottom of being fixed in this metastomium 31.Opening edge forms outside curled portion 33 above metastomium 31, is formed with outwards outstanding horizontal ribs 34 and inwardly outstanding horizontal ribs 35 on metastomium 31.Between the outside of the metastomium 31 of the inner face of the sidewall 21 of sleeve 20A and cup main body 20B, be formed with insulated space.On the inner face of cup main body 20A, be coated with polyolefin resin.On the sidewall 21 of sleeve 20A, be provided with relative a pair of grip flaps 23,23 mutually.In Fig. 5 A, Fig. 5 B, Fig. 5 C, only shown the grip flaps 23 of a side in addition.The external diameter of the upper end open portion of cup main body 20B is set greater than the height of container 20.

Shown in Fig. 5 A, Fig. 5 B, Fig. 5 C, the formation of the insulated space of heat-insulated container 20 is by being located at inwardly curling 22 realizing of the outwards outstanding horizontal ribs 34 of glass metastomium of main body 20B 31 and the bottom that is formed at sleeve 20A.Just, under laying state (without the hand hold vessel but place it in state on the desk), do not need the sidewall 21 of sleeve 20A and the horizontal ribs 34 of outwards giving prominence to contacts.

The main effect of horizontal ribs 34 is the metastomium 31 of reinforcement cup main body 20.And horizontal ribs 35 also is used to indicate the graticule of the appropriate amount of the hot water that injects cup main body 20 in reinforcement metastomium 31.

Fig. 6 is the expansion drawing that is used to make the blank of sleeve 20A.

The blank 20A ' of sleeve 20A is the blank that paperboard is die-cut into fan-shaped as shown in Figure 6.The both ends, the left and right sides of blank 20A ' form metastomium paste section N, and the bottom forms the curling forming section C of inside curled portion 22.The forming section C part in addition of curling is the part of the sidewall 21 of formation sleeve 20A.

The sleeve 20A of the mutual bonding formation rounding frustum shape of the metastomium paste section N of blank 20A '.Going up stamping-out at blank 20A ' has a pair of grip flaps 23,23 by broken line 25 and joint-cutting line 24 zonings, and they are on being formed at sleeve 20A the time, mutually the subtend location.And broken line 25 is along the circular arc setting of blank 20A '.

Fig. 7 A, Fig. 7 B are the enlarged drawings of the grip flaps 23 on the blank 20A '.

Fig. 7 A is the figure that shows a kind of mode of grip flaps 23.Grip flaps 23 is by the linearity of 2 p1, p2 on the circular arc that links the circular arc parallel with the periphery of blank 20A ', promptly extends at a certain distance with respect to the periphery of blank 20A ' or by the curvilinear broken line 25 of the downward lateral bending song of this straight line with link the two ends (p1, p2) of this broken line 25 and to joint-cutting line 24 zonings of the lower knuckle of broken line 25.And grip flaps 23 can be bent laterally by broken line 25.

In the way of joint-cutting line 24, be formed with connecting part 26.

Connecting part 26 is to be configured as sleeve 20A and to be assembled on glass main body 20B in order grip flaps 23 to be bound on the sidewall 21 until blank 20A ', when using grip flaps then till.Connecting part 26 preferably has the width about 0.3～1.0mm (is under the situation of 0.2～0.5mm at paper mold thickness), can only destroying with the power of finger tip when using grip flaps.Usually, when paper being strutted cut-out, cut off than more needing power along cutting off with the direction of paper line quadrature along paper line direction.Therefore, be provided with under the situation of a plurality of connecting parts 26 in a side of joint-cutting line 24, preferably the Width of each connecting part 26 is more near the width of all the more big connecting part 26 of direction parallel with paper line direction shown in the arrow among the figure.Can make the cut-out power of each connecting part even thus.

The lower periphery of grip flaps 23 is formed with otch 27.Otch 27 is used for pull-up grip flaps 23 when forming grip flaps 23.The size of otch 27 is as long as user's finger tip or nail can enter.Otch 27 preferably is positioned at the foot of grip flaps 23.

Fig. 7 B shows the another kind of mode of grip flaps.In this mode, replace otch 27, be provided with little broken line 25 ' in the lower periphery of grip flaps 23.According to this structure, can the part of this bending can be pulled out grip flaps 23 integral body as holding plate along little broken line easily with the bottom bending of grip flaps 23.

Shown in Fig. 7 B, preferably be provided with as drawing the fillet 24a of arc as returning to the bottom of grip flaps 23 in the end of joint-cutting line 24.Because the direction that extend the end of joint-cutting line 24 is near the direction parallel with the paper line, so terminal p1, the p2 of the suture 24 of might autotomying when pulling out grip flaps 23 tear blank 20A ' upward, this possibility can be separated and disappears by appending fillet part 24a.

Above broken line 25, little broken line 25 ', joint-cutting line 24, connecting part 26 and otch 27 can form simultaneously with the Punching Technology of blank 20A '.Therefore, the processing of these key elements can not become the factor of the manufacturing cost raising that makes heat-insulated container 20.

Most of zone of blank 20A ' is printed before the processing of blank 20A ', be the part of performance as the effect of information medium, but the processing of above grip flaps 23 can not hinder printing effect or appearance greatly.

Fig. 8 A, Fig. 8 B show the running condition of the heat-insulated container 20 of above-mentioned band grip flaps.

Fig. 8 A is the lateral plan of the state that shows that the grip flaps 23 of the heat-insulated container 20 of band grip flaps of the present invention is raised;

Shown in Fig. 5 A, Fig. 5 B, Fig. 5 C, grip flaps 23 makes broken line 25 be positioned at upside, is arranged on the inverted cone curved surface.Here, when the double container in supposition no space between the metastomium 31 of the sidewall 21 of sleeve 20A and dixie cup main body 20B, when foot pull-up grip flaps 23, to take efforts, understand on the grip flaps 23 of pull-up, producing fold.When the paperboard that peel strength is low is used for sleeve 20A, paperboard is produced tear.

But, under the situation of the heat-insulated container 20 of the band grip flaps of Fig. 5 A, Fig. 5 B, Fig. 5 C, owing between the metastomium 31 of the sidewall 21 of sleeve 20A and dixie cup main body 20B, have the space, so when pulling out grip flaps 23, can make the sidewall 21 of the middle body of broken line 25 be out of shape power pull-up grip flaps easily 23 that can be less to the direction shown in Fig. 8 A arrow.Broken line 25 is from opening easness, and is preferably crooked to the below slightly of the line of 2 p1 of the horizontal direction that links the rounding conical surface, p2 shortest distance.Be under the situation of broken line of 50mm for example, preferably in the central about the crooked downwards 0.5～2.0mm of portion in length.

Along these broken line 25 pull-up grip flaps 23 time, make sidewall 21 distortion as mentioned above, lift and the distortion of turning back slightly about while grip flaps 23, its result, shown in Fig. 8 A, grip flaps 23 is maintained at and the roughly rectangular position of sidewall 21.If press grip flaps 23, then can return original state (being roughly with state simultaneously) with the sidewall 21 of sleeve 20A.

Fig. 8 B is the block diagram that will heat modulation state before that shows the heat-insulated container 20 of band grip flaps.

Heat-insulated container 20 no matter hot water modulation heating still the micro-wave oven heating all can use easily.Under the situation of the grip flaps shown in Fig. 7 A 23, before the heating modulation, finger tip or nail insertion otch 27 are lifted grip flaps 23 upward.Under the situation of the grip flaps shown in Fig. 7 B 23, before heating modulation, by little broken line 25 ' leading section of grip flaps 23 being turned back forms holding plate, clamps this holding plate grip flaps 23 is lifted upward with pointing.Like this, shown in Fig. 8 A, Fig. 8 B, the grip flaps of lifting 23 is held in approximate horizontal, under this state, heats modulation and get final product.

In addition, under the situation of hot water modulation heating, after opening a cover piece L and injecting hot water, seal cover piece L once more and placed 3～4 minutes.Under the situation of micro-wave oven modulation, as long as heating modulation under the state of opening cover piece L a little.

After the modulation, by taking grip flaps 23 with two hands, can under the situation of sensible heat not, will heat the position that food after modulating is transported to regulation safely with each container.

Under the situation of using the bowl-shape container in common sea, need ride over its edge with finger and transport container, at this moment, there is the problem of this health of finger contact food aspect.Utilizing grip flaps 23 to take under the situation of fortune, this problem has also solved.

In addition, also can by in advance to grip flaps 23 carry out embossing processing or in advance method such as local coating slip proofing agent prevent the slip of grip flaps 23.

In above heat-insulated container 20, use the identical base material of base material that uses with existing heat-insulated container made of paper, the big very big bowl type heat-insulated container made of paper of the peristome external diameter with 120～200mm φ can be provided.Internal volume is the heat-insulated container of 600～1500cc when filling with.

Even being used for the paperboard base material internal volume increase of the shaping of heat-insulated container 20 also can use and the existing roughly the same heavy base material in level ground.

Usually, with the scope of 20～80 μ m, extrusion coating is formed with polyolefin type resin layers such as ldpe resin, medium density polyethylene resin, high-density polyethylene resin, wire ldpe resin on the inner face of cup body paper.

This polyolefin type resin layer is except that preventing content soaking into, improving the content protective adaptation to paperboard; also bring following effect; improve the cup formability of bottom, curled portion, metastomium paste section, improve by cover piece (not shown) and stitch the sealing property of bringing in the hot pressing of top curled portion.

The level ground of the body paper of cup main body 20B heavily is 190～450g/m ²About.

On the other hand, in the shaping of sleeve 20A, can use the level ground to weigh 230～450g/m ²The paperboard of card-like, coating stationery etc.If during heavily discontented this limit in level ground, the rigidity deficiency of sleeve 20A, when temperature is high deflection excessive, might can not get the thermal insulation that needs.And when the level ground heavily surpasses above-mentioned limit, though rigidity increased, the inside flexibility (adaptability) of operation variation of curled portion 22, material cost also can increase, so undesirable.

The surface working of sleeve 20A is under the situation of existing heat-insulated container, and glazing processing is just enough, but under the situation of the heat-insulated container 20 of being with grip flaps, because grip flaps 23 will be installed, so preferably make it have tear resistance by surface working.In addition, the food that the heat-insulated container of band grip flaps of the present invention is adorned preferably has fastness to water under the situation with cooling, freezing state circulation.

Therefore, can have following lamination structure in regular turn from the surface beginning.

PE30 μ m/ paper 270g/m ²

PE20 μ m/ paper 270g/m ²/ PE20 μ m

OPP30 μ m/PE15 μ m/ paper 270g/m ²

PET12 μ m/PE15 μ m/ paper 270g/m ²

OPP30 μ m/PE15 μ m/ paper 270g/m ²/ PE15 μ m

PET12 μ m/PE15 μ m/ paper 270g/m ²/ PE15 μ m

In addition, also can use the water-fast two sides coated paper of having given fastness to water in the system paper stage.Can on the preceding sheet paper of stamping-out blank 20A ', carry out preprinted, printing degree of freedom height to the surface of sleeve 20A, not only known printings such as offset printing, intaglio, aniline printing can be freely implemented, and printing back processing such as various glazings, gold stamping, embossed can be freely implemented.In addition, though will carry out the processing of aforementioned grip flaps 23 after printing, this processing does not influence planeness, but the decorative effect of printing, information medium function former state keep.

Even Fig. 5 A, the heat-insulated container 20 of Fig. 5 B, Fig. 5 C, also owing to be from polyolefin resin, further to select natural resin to be used for the coating of inner face, so and the heat-insulated container 10 of embodiment 1, embodiment 2 have relieved sense equally.

The heat-insulated container 20 of the band grip flaps of Fig. 5 A, Fig. 5 B, Fig. 5 C can be with the order manufacturing same with the heat-insulated container 10 of embodiment 1, embodiment 2.But, be paperboard stamping-out when becoming fan-shaped at raw material with sleeve 20A, need carry out the processing of grip flaps 23 simultaneously, thereby make blank 20A '.

The size of the embodiment sample of the heat-insulated container 20 of the band grip flaps of Fig. 9 displayed map 5A, Fig. 5 B, Fig. 5 C.Detailed specification is as follows.In addition, prepared except that not forming the identical comparative example of grip flaps 23 specifications.

The polyolefin type resin layer of the inner face of the heat-insulated container 20 of band grip flaps of the present invention can not separated out the suspicious material such as polystyrene foamed appreciiable environmental hormone that present heat-insulated container uses, and can give relieved sense aspect health.

Cost that grip flaps 23 brought is set rises and almost do not have, reasonably financial cost provides heat-insulated container.

Heat-insulated container of the present invention uses the back discarded as paper products, easy capacity reducing, so waste treatment is good, and also recyclable, so can help alleviating environmental load.

Figure 10 shows that Figure 11 summary shows the manufacturing step of this dixie cup as the dixie cup of the heat-insulated container of the embodiment of the invention 4.

As shown in figure 10, dixie cup 41 is made of with sleeve 43 assemblings that are coated on its periphery the dixie cup main body 42 as container body.Cup main body 42 forms roughly truncated cone, has metastomium (sidewall) 42a and bottom 42b.Bottom 42b becomes its outer circumference end stretch process downwards to bend in Figure 10, and like this, 42b its section form in Figure 10 in bottom forms to roughly " コ " of under shed font.Metastomium 42a wraps into the kink of peripheral part of this bottom 42b and bonding from the outside.Like this, form the line tail 42f of cup main body 42.

Oral area in cup main body 42 is provided with the curled portion 42c that curls laterally.Metastomium 42a in cup main body 42 is provided with rib 42d, 42e around one week of metastomium 42a respectively.Rib 42d is interior side-prominent to metastomium 42a's, and rib 42e is outstanding to the outside of metastomium 42a.Utilize these ribs 42d, 42e reinforcement cup main body 42.The rib 42d of upside is the graticule of an amount of position of the infusion (for example hot water) of conduct demonstration cup main body 42 also.The rib 42e of downside is bigger than rib 42d.Rib 42d, 42e overhang separately is advisable not contact with the inner face of sleeve 43.

In addition, rib 42d also can be outstanding to the outside of cup main body 42, and what rib 42e also can be to cup main body 42 is interior side-prominent.

The base material of cup main body 42 for example uses, and the level ground weighs 150～400g/m ²Paper (for example paper of thick 0.3～0.34mm).At least the inner face of cup main body 42 is coated with the coating (for example polyethylene layer) that is used to improve resistance to effect of heat or fastness to water.In addition, same with the various embodiments described above, preferably in polyolefin resin, further select natural resin to be used for the coating of glass main body 42.

Sleeve 43 is to establish for the thermal insulation that improves the cup main body.As shown in figure 10, be formed with the curled portion 43a that inwardly curls in the lower end of sleeve 43.The upper end 43b of sleeve 43 is bonding with the metastomium 42a of cup main body 42, and simultaneously, curled portion 43a is relative with the side of the line tail 42f of cup main body 42.Curled portion 43a plays separaant, and sleeve 43 is left from cup main bodys 42, like this, and the space that between the metastomium 42a of cup main body 42 and sleeve 43, can guarantee the thermal insulation layer effect.The base material of sleeve 43 for example uses, and the level ground weighs 150～400g/m ²Paper.In addition, sleeve 43 is not owing to specially contact with hot water or water, so can omit the such coating of glass main body 42 yet.

As shown in figure 11, behind bonding metastomium 42a and bottom 42b, thereby form a rib 42d and a rib 42e formation cup main body 42.Both ends 43c, the 43c of bonding sector 43 ' form sleeve 43 thereby form inside curled portion 43a in the lower end.Then, lining cement is sprayed at bonding scope (the hachure zone of Figure 11) BD of the regulation of the curled portion 42c below that is set in glass main body 42, assembling cup main body 42 and sleeve 43, the upper end 43b of sleeve 43 is bonding mutually with the metastomium 42a of cup main body 42, form dixie cup 41 (bonding scope BD is referring to Figure 16 A, Figure 16 B).

In addition, under situation about bloating outside the radial direction of cup main body 42, bonding scope BD is set at and does not relate to rib 42d at rib 42d.

Figure 12 is the amplification profile of the curled portion 43a periphery of demonstration sleeve 43, and Figure 13 A, Figure 13 B, Figure 13 C and Figure 14 A, Figure 14 B, Figure 14 C are the section-drawing of the shape of explanation curled portion 43a.What Figure 12～Figure 14 C showed cup main body 42 is set at centre line C L vertical section under the vertical direction situation.

As shown in figure 12, the lower end of line tail 42f promptly the lower end that protrudes in curled portion 43a, the lower end of cup main body 42 be the below, lower end of sleeve 43.Therefore, under situation about dixie cup 41 being placed on the desk etc., direct contacts such as the cup main body 42 that content is housed and desk.The line tail 42f of cup main body 42 is very solid, and the planeness of its lower end (height homogeny) better.Therefore dixie cup 41 is very stable.In addition, " A " among Figure 12 shows the overhang of cup main body 42 from curled portion 43a.

Relative therewith, suppose under the situation that the lower end of curled portion 43a and desk etc. contact, then because the planeness of the lower end of curled portion 43a is poorer than line tail 42f, and, by sleeve 43 support cup main bodys 42, can cause the distortion of sleeve 43, so the bad stability of dixie cup 41.

Preferably give prominence to the overhang of 0.01～0.05mm with respect to the lower end of curled portion 43a the lower end of line tail 42f.In this scope, then cup the outstanding visual of main body 42 can not noted, and line tail 42f contacts desk etc. reliably, and dixie cup 41 is stablized.

In addition, make the lower end of container body protrude in the structure of below of lower end of sleeve also applicable to the heat-insulated container that does not form the line tail on situation that does not form inside curled portion on the sleeve or the cup main body.

As shown in figure 12, the circumferential position of the lower end of line tail 42f is than the centre line C L side of position (end of interior all sides of curled portion 43a) the more close cup main body 42 of the centre line C L of the most approaching cup main body 42 of curled portion 43a.Between the lower end of the periphery of Figure 12 " B " expression line tail 42f and the curled portion 43a in the addendum modification of the radial direction of cup main body 42.By this addendum modification being set in the scope of 0.01～1mm, can guarantee the stack-mounted smoothness, suppress the distortion of dixie cup 41 simultaneously.In addition, the position of the centre line C L of the most approaching cup main body 42 of curled portion 43a and between the side of the line tail 42f at this position, be formed with the gap.By this gap (" D " among Figure 12) being set in the scope of 0.01～1mm, can guarantee the stack-mounted smoothness, suppress the distortion of dixie cup 41 simultaneously.

In Figure 12 and Figure 13 A, Figure 13 B, Figure 13 C, the direction (equaling the direction of the line of centers of glass main body 42) of " X " expression vertical axis, the front end indicated direction of the paper of " Y " expression coiling pars convoluta 43a (direction that the front end of curled portion 43a is prolonged).As shown in figure 12, in curled portion 43a, the front end of coiling paper forms along the rotating state of cw until the direction towards surpassing vertically upward of the front end of the paper of reeling.Thereby, when assembling cup main body 42 and sleeve 43, make line tail 42f be difficult for the front end of lash in the paper of curled portion 43a, can both be assembled swimmingly.

Relative therewith, in Figure 13 A, the front end of paper be not wound up into paper front end towards the direction that arrives vertically upward.Like this, in the front end no show direction vertically upward of paper, curled portion 43a forms under the situation of the state of upwards opening, and when assembling cup main body 42 and sleeve 43, line tail 42f meeting lash presses off curled portion 43a, so undesirable easily in curled portion 43a.

In Figure 13 B, expression paper is wound up into its front end and surpasses vertically upward direction and form a example along the rotating state of cw, and line tail 42f is difficult for lash in curled portion 43a.In Figure 12, the state that the front end of the paper of expression curled portion 43a is further reeled to clockwise direction from the state of Figure 13 B, line tail 42f more is difficult for lash in curled portion 43a.

In Figure 13 C, though the front end of the paper of curled portion 43a towards the direction that does not arrive vertically upward, the front end of this paper more is positioned at the lateral direction of container than the position of the centre line C L of the most approaching cup main body 42 of curled portion 43a.In addition, the perpendicular line that joins with inner peripheral surface of Figure 13 C " P " expression curled portion 43a is the position of horizontal direction of the centre line C L of the most approaching cup of curled portion 43a main body 42.

Like this, as long as the front end that satisfies this paper more is positioned at this condition of lateral direction of container than the position of the centre line C L of the most approaching cup main body 42 of curled portion 43a, just then line tail 42f is difficult for lash in curled portion 43a.In addition, Figure 12 and Figure 13 B all represent to satisfy the situation of above-mentioned condition.On the other hand, in Figure 13 A, the centre line C L of the most approaching cup of the leading section of paper main body 42 is not so satisfy above-mentioned condition.In this case, line tail 42f is easy to lash in curled portion 43a.

And then the gap between the front end of the paper by making coiling pars convoluta 43a and the internal face of sleeve 43 then when assembling cup main body 42 and sleeve 43, makes line tail 42f be difficult for lash in curled portion 43a less than 1mm.In addition, by making the thickness of this gap less than line tail 42f, line tail 42f enters the inboard of curled portion 43a and possibility that curled portion 43a is pressed off when then significantly reducing assembling from this gap.Figure 14 A, Figure 14 B and Figure 14 C represent that respectively this gap is C1, C2 and C3 (situation of C1＞C2＞C3), the consistency of thickness of the C2 of Figure 14 B and line tail 42f.Figure 14 C is equivalent to the curled portion 43a of Figure 12.

Figure 15 A is near the section-drawing the display line tail 42f.Shown in Figure 15 A, line tail 42f pours into to container inside, with than the outside wall surface of the metastomium 42a that makes line tail 42f top and the more close container inside of extended line R.Like this, tilt to container inside, when assembling cup main body 42 and sleeve 43, make line tail 42f be difficult for lash in curled portion 43a by making line tail 42f.

Shown in Figure 15 A, the front end overlap 42g of online tail 42f is outstanding to container inside.In the Fabrication procedure of cup main body 42, after forming line tail 42f, form curled portion 42c, but in the formation operation of curled portion 42c, for fixed cup main body 42, the leading section of online tail 42f line tail 42f brute force pressed on the mould parts, so will inevitably produce overlap.But, by shown in Figure 15 A that the overlap formation is outstanding to container inside, and do not produce to the outstanding overlap of outside of containers, can further make line tail 42f be difficult to lash in curled portion 43a.

In Figure 15 B, the line tail extends along the extended line R of metastomium (sidewall), and simultaneously, overlap 42h protrudes in outside of containers.This shape is equivalent to common dixie cup, but because cup main body 42 when forming such shape, overlap 42h is projected into the outside of extended line R, so the line tail is easy to hang at curled portion 43a.

Pour into to container inside for line tail 42f is formed, as long as when forming line tail 42f at superimposed bottom 42b and metastomium 42a, to apply the pressure that line tail 42f is overwhelmed to container inside, mutual bonding bottom 42b and metastomium 42a get final product simultaneously.For example, with knurling rolls when bonding,, make simultaneously to form from the side of the swivel of inboard pusher wire tail 42f and accept the conical surface that parts match and get final product as long as the continuing surface of accepting parts of accepting line tail 42f from the outside is tilted to container inside.Online tail 42f is in advance to the inside under the bevelled situation, and the overlap that for example results from line tail 42f front end in thereafter operation in the formation operation of curled portion 42c is outstanding to the inside, so can finally form the line tail 42f of shape shown in Figure 15 A.

Also can after forming the line tail, before forming curled portion 42c, exert pressure to the line tail, the line tail is processed into shape shown in Figure 15 A, also can be when forming curled portion 42c, use and support the mould parts what the front end of line tail was drawn in inboard shape, cup main body 42 is fixing.In the latter case, when forming curled portion 42c, the leading section of line tail integral body or line tail can be poured into to the inside.

Figure 16 A places the vertical cross section of the bonding portion of cup main body 42 under the situation of vertical direction and sleeve 43 for showing centre line C L with cup main body 42.Shown in Figure 16 A, metastomium 42a is bent to form, and the position relative with bonding scope BD tilts to container inside with respect to the extended line (straight line of Figure 16 A " S ") at the position of this below, position.Thus, the direction of the metastomium 42a of bonding scope BD is consistent with the direction of sleeve 43, and both are contact closely well, so can obtain sufficient adhesion strength.In addition, the direction of the metastomium 42a at the bonding scope BD of the straight line of Figure 16 A " T " expression place.Also can not make metastomium 42a bending, and shown in the vertical cross section of Figure 16 B, make sleeve 43 bendings, it is contacted closely with metastomium 42a.

In Figure 16 A, straight line " U " expression is by the horizontal surface of the lower end of curled portion 42c, and straight line " V " expression is by the horizontal surface of the upper end of bonding scope BD, and straight line " W " expression is by the horizontal surface of the lower end of bonding scope BD.Here, the width that makes the vertical direction of bonding scope BD is that the straight line " V " of Figure 16 A and the distance of straight line " W " are got more than the 3mm, obtains sufficient adhesion strength thus.Distance between the lower end of the upper end of bonding scope BD and curled portion 42c is that the straight line " V " among Figure 16 A and the distance of straight line " U " are got more than the 1mm in addition, and like this, lining cement can be not on the curled portion 42c attached to the position of user's mouth contact just.And the upper end of the bonding scope BD shown in the straight line " V " is positioned at the below of the upper end 43c of sleeve.Like this, lining cement just can not overflow from the upper end of sleeve 43 43c side.

When making dixie cup 41 according to operation shown in Figure 11, be pre-formed glass main body 42 and sleeve 43, by bonding scope BD bonding both, the scope of difference of internal diameter that makes the sleeve 43 at external diameter under the curled portion 42c of glass main body 42 position of " E " expression (among the Figure 10 with) and this position is-0.1～+ 0.5mm.By adopting such size relationship, can guarantee enough bonding forces at bonding scope BD place, simultaneously, can not produce fold at the metastomium 42a of cup main body 42 yet.

As shown in figure 17, also can make the curled portion 43a of sleeve 43 relative with the metastomium 42a of line tail 42f top.In this case, the gap of curled portion 43a and metastomium 42a (D ') is set at the scope of 0.01～1mm, like this, can suppress the distortion of dixie cup 41, simultaneously, also can not produce fold at metastomium 42a.

In the dixie cup 41 of present embodiment, the scope that the radius of curvature (radius of curvature of the section among Figure 12) of the paper of formation curled portion 43a is preferably got 0.6～2.0mm.By being set in this scope, paper can not torn, and when assembling cup main body 42 and sleeve 43, the line tail 42f lash that can prevent glass main body 42 can be assembled swimmingly in curled portion 43a.The better scope of above-mentioned radius of curvature is 1.1～1.5mm.In Figure 18 A～Figure 18 D, shown the example of the shape of the curled portion 43a that this radius of curvature reduces successively respectively.That is R1＞R2＞R3＞R4.In addition, the shape of curled portion 43a shown in Figure 12 is corresponding with Figure 18 D.

Figure 19 A and Figure 19 B are the partial enlarged drawings of fan-shaped blank 43 '.Label 51 expressions of Figure 19 A and the congruent region of the other end cementation laminated of blank 43 ', the zone (referring to Figure 11) of label 52 expressions formation curled portion 43a.Shown in Figure 19 A, zone 51 and zone 52 are overlapped in the bight of blank 43 '.Be formed with the notch 53 that angle that straight line cuts away blank 43 ' forms at this repeating part.Notch 53 is arranged on the end that is disposed at a side of container inside in the both ends of bonding blank 43 ', so that unshowy in appearance.

Shown in Figure 19 A, the zone of being cut away by notch surpasses extends upward with curled portion 43a cooresponding regional 52.Shown in Figure 19 B, utilize notch 53, reduced more than 50% with overlapping area among the curled portion 43a cooresponding regional 52.That is, in Figure 19 B, in the overlapping overlapping region in the zone 52 before label 54 expression is sheared and the zone 51 because zone that the formation of notch 53 is cut off, regional 54 account for the area of overlapping region single-piece more than 50%.

By such notch 53 is set, blank 43 ' the overlapping part also can form continuous curly form, and the integral body of curled portion 43a can obtain good shape.

With curled portion 43a cooresponding regional 52 in, on the outer peripheral face of sleeve 43, be coated with OP varnish (glazing varnish).The protective cover of the printing surface that forms on the outer peripheral face of this OP varnish as sleeve 43 utilizes printing to wait coating on printing surface.For example, under the situation of intaglio, use with celluosic resin, under the situation of offset printing, use with acrylic resin to be OP varnish of main component etc. to OP varnish of main component etc.Its thickness under the situation of intaglio, is about 2～3 μ m, under the situation of offset printing, is about 1 μ m.

The protective cover that is made of this OP varnish is when forming curled portion 43a, and the reduction friction layer good as the slip that makes blank 43 ' works, so by protective cover is set, can easily form curled portion 43a.

In the above-described embodiments, illustrated that the OP varnish double as that is used in the protection printing surface reduces the situation of friction layer, but also can the reduction friction layer different with the protective cover of printed layers be set in addition regional 52.Under the situation of the protective cover that does not form printed layers, also can 52 formation reduce friction layer in the zone.And, can be located on the inner face (towards the face of container center) of sleeve 43 reducing friction layer, also can be formed on inner face and the two sides, outside.

In addition, in Figure 10, as the external diameter of the peristome cup-shaped dixie cup 41 that shown less than height, but same with the foregoing description 1～embodiment 3, dixie cup 41 also can form big very big bowl or the alms bowl shape of the external diameter of peristome greater than height.Also can on sleeve 43, grip flaps be set.

Figure 20 shows that Figure 21 shows the summary step of making this dixie cup as the dixie cup of the heat-insulated container of the embodiment of the invention 5.

As shown in these figures, dixie cup 61 is by constituting as the dixie cup main body 62 of container body and the sleeve 63 of its periphery of coating.Cup main body 62 forms roughly truncated cone, has metastomium (sidewall) 62a and bottom 62b.Oral area in cup main body 62 forms curled portion 62c laterally.After forming curled portion 62c, form rib 62d, the 62e that bloats to the radial direction inboard or the outside of cup main body 62 respectively at metastomium 62a.Rib 62d is provided with as the graticule of an amount of position of the infusion (for example hot water) that shows cup main body 62.And rib 62e is used for reinforcement cup main body 62.Rib 62e is bigger than rib 62d.Rib 62d, 62e overhang separately is advisable not contact with the inner face of sleeve 63.The base material of cup main body 62 for example uses, and the level ground weighs 150～400g/m ²Paper, its inner face is covered by the coating that is used to improve resistance to effect of heat and fastness to water (for example polyethylene layer) at least.In addition, rib 62d also can be outstanding to the outside of cup main body 62, and what rib 62e also can be to cup main body 62 is interior side-prominent.

Sleeve 63 is to establish for the thermal insulation that improves the cup main body.As shown in Figure 21, both ends 63c, the 63c of bonding fan-shaped blank 63 ' form sleeve 63 thereby the lower end forms the curled portion 63a that inwardly curls.Then, lining cement 64 is coated on bonding scope (the hachure zone of Figure 21) BD of the regulation under the curled portion 62c that is set in glass main body 62, assembling cup main body 62 and sleeve 63, the upper end 63b of sleeve 63 is bonding mutually with the metastomium 62a of cup main body 62, form dixie cup 61.In addition, under situation about bloating outside the radial direction of cup main body 62, bonding scope BD is set at and does not comprise rib 62d at rib 62d.The base material of sleeve 63 for example uses, and the level ground weighs 150～400g/m ²Paper.Sleeve 63 not can with situation that hot water or water contact under, needn't the such coating of glass main body 62 be set at sleeve 63.

As shown in figure 22, the section form of curled portion 62c is the shape that will just justify along axis direction (above-below direction of Figure 22) conquassation of cup main body 62, in other words, be flat pattern, produce very thin curve 62f in its outer circumference end in direction with the axis direction quadrature of cup main body 62.When the thickness of establishing glass main body 62 is t, the height A of the axis direction of curled portion 62c and and the width B of the direction of its quadrature between have the relation of following formula (1).

2t＜A＜B …(1)

That is to say that the height A of curled portion 62c is than 2 times big of the thickness t of cup main body 62 and less than the width B of curled portion 62c.Like this, as long as make curled portion 62c form flat pattern, then when the cover piece 66 with film like is pasted on curled portion 62c, can enlarge the width C that curled portion 62c and cover piece 66 engage by lining cement 65, the intensity that can stipulate is engagement with cap 66 reliably.In addition, the appropriate scope of bond strength is according to the kind that is contained in glass main body 62 in-to-in article and difference.As an example, as instant noodles, under the state that cover piece 66 parts are peeled off, in cup main body 62, inject hot water, under the situation through removing cover piece 66 behind the certain hour, can set bond strength, making the power of peeling off cover piece 66 is 400～900gf/15mm.

In addition, in Figure 20, dixie cup 61 has been drawn as the sea bowl-type of the external diameter of peristome greater than height, but the external diameter that dixie cup also can be used as peristome constitutes less than the cup-shaped heat-insulated container of height.Will print trade mark etc. on the outer peripheral face of sleeve 63, this printing can be carried out in the stage of blank 63 '.Below the face that will print is called the surface of blank 63 ', and the face of its opposite side is called the back side.
