The insulating insert is similar in shape to the outer sidewall blank but smaller in size. The insert is glued in a centered position to the non-printed side of the sidewall blank to form a two-layered insulating wrapper. Less than 20% of the area of the insert is glued to the base sheet.
Description
The cross reference of related application
The application is that sequence number is No.10/831,411, and the existing resigned part continuation application of submitting on April 22nd, 2004 that I apply for.
Technical field
The present invention relates generally to heat-insulating disposable cup and container, particularly heat insulating packaging thing, the method for manufacturing heat insulating packaging thing and the method for making heat-insulated container of the heat insulating packaging thing.
Background technology
The cup and the container of existing number of different types, every kind all has one group of specific characteristic, relates to printing quality, rigidity, thermal insulation, biodegradability, recyclability, diaphaneity, penetrablility, microwave availability and shelf-life, and other characteristic.The cup of number of different types has desirable characteristics and benefit aspect one or more, but has not satisfied characteristics in others.
For example, well-known by the cup that expanded polystyrene (EPS) is made in this area, be good heat insulator and the temperature that can keep beverage for a long time, no matter beverage is a heat or cold.They can also provide isolation layer between the heat of product or cold temperature and user's hand.It is unfavorable to environment that yet the EPS cup is considered to usually, because they are not biodegradable.The result is that they are under an embargo in some place.In addition, in order to print the EPS cup, must use at a slow speed and expensive off line typography, because this cup must form the back printing at them, and their more coarse surfaces do not allow the fine resolution printing.
Usually be considered to more favourable to environment at standard single-part stationery container well-known in the art equally, but their thermal insulation is very poor than EPS cup.Therefore, a lot of caves solve with double-deck a set of cups, and this method is exactly that hot beverage is contained in the individual layer dixie cup of two stacks, so that thermal insulation to a certain degree is provided.The very high and very waste of expense like this.Alternately, the designer provides the glass holder of multiple parcel individual layer dixie cup to keep drink warm comfortable with hand so that thermal insulation to be provided; Referring to, for example license to the US Patent 5,205,473 of Coffin (1993), license to Sanchez (1998) 5,794,843 and license to people's (2001) such as Neale 6,277,454.A shortcoming of glass holder is glass holder must be installed and/or is placed on the cup when presenting beverage, and this needs extra work and has reduced service rate.In addition, require extra and buying simultaneously, extra storage area and extra material requirements planning for the demand of cup and glass holder.Glass holder also has landing and leaves the tendency of cup, can not be fit to easily in all vehicle glass stands, and cover in the pattern that is printed on the cup.
Well-known in the art is that the single wall plastic cup is made with following material, for example polyethylene terephthalate (PET), polystyrene (PS), polypropylene (PP) and high density polyethylene (HDPE) (HDPE); And by thermoforming or injection molding process formation.Thereby plastic cup is attractive in appearance and can make and have high isolation performance and provide the long shelf-life for the product that holds in it.Can also add the isolated material that is called as EVOH provides better oxygen to isolate.The cup of making by thick-layer HDPE can provide the obvious results water separation from.By the plastic cup that HDPE and two kinds of materials of EVOH are made moisture and oxygen are all resisted, thereby provided the longer shelf-life for its product that holds.The plastic cup of some type, for example the cup of being made by polypropylene can tolerate high heat, therefore can be used for microwave.In addition, plastic cup does not have seaming zone, and this makes their compare leakproof.Yet plastic cup must form laggard capable off line printing at cup, and this is the technology of high cost and the capacity that has limited pattern.Another problem is that these cups are very poor thermal isolation bodies.The very fast forfeiture heat of their meetings or cold, and when filling hot or cold content, grip uncomfortable.Another weak point is that the rigidity intensity of their sidewalls is very poor.
Designed the multilayer dixie cup thermal insulation to be provided and to gain in strength.License to the U.S.Pat.Nos.3 of Shikaya (1975), 908,523, license to 5,205 of Coffin (1993), 473, license to 5 of Mueller (1996), 547,124, license to 5,685 of Choi (1997), 480, license to people's such as Morita (1998) 5,769,311, license to 5,775 of Titus (1998), 577, license to people's such as Dees (2000) 6,039,682 and license to people's (2001) such as Blok 6,253,995, all show at least three layers multilayer cup, it comprises the interior cup that is made of paper of certain form and heat-insulating outer cover or packing material is provided.Packing material comprises the multilayer tablet sheet material, this sheet material constitute at least one deck substrate and at least one deck be bonded in described on-chip ripple or relief sheet.The manufacturing expense costliness though these cups are heat insulation and firm is because ripple or relief sheet must pass through the bonding whole surface with covering substrate of laminating technology.This technology is by with adhesives, and polyethylene for example hot melt or heating, or paste-type adhesive starch base low temperature glue for example are coated on the surface of relief sheet and/or substrate, then two kinds of sheet material pressings are formed the multilayer tablet heat insulation sheets.From this multilayer tablet sheet material, cut out (being called as die-cut technology) packing material then, then around wrapping up and be adhered to interior cup.Expensive and the waste with the coarctate cost of technology of sheet layer.There are the multilayer tablet sheet material processing leftover pieces that have added value in a large number when die-cut packing material, to be wasted.Also having a large amount of adhesivess to be used at the fixing relief sheet of whole substrate surface, generally is to carry out along the top of all ripples or projection.The typography costliness, because substrate must print before lamination, this can cause serious aligning and distortion problem after sheet material is laminated on together, perhaps owing to the thickness of multilayer tablet sheet material and the supercompression of stiffness and sheet material, the multilayer tablet sheet material is printed with difficulty behind the sheet material lamination.In any case it is very difficult providing high quality printing with cost effective price on the heat insulation cup of these types.At last, because the limited flexibility of thick laminate cardboard makes multilayer tablet laminate packaging thing very difficult around interior cup parcel or bending.
6,085,970 the heat insulation cup that licenses to the patent No. 5,660,326 of Varano and Sadlier (the present inventor) (1997) and license to Sadlier (2000) has overcome these deficiencies.These cups on market, won extensive approval and global marketing millions of more than.Though the cup of these two patents is significant improvement, find that in person the manufacturing process of described cup and they can further be improved.Because interior cup and skin are made by continuous blank, these two parts are just made by identical materials.This is disadvantageous, and is because internal layer must be used for waterproof with the polyethylene coating plate manufacturing of costliness, therefore outer also necessary with same expensive material manufacture.Equally, because internal layer is to make with identical blank with skin, whole blanks, and be not the outer layer segment of blank, must be by printer, this is the technological operation of comparison costliness.Sidewall blank also must fold so that formed the internal layer and the skin of cup by identical elongate blank.The technology of collapsible blank is to need the accurately additional step of the costliness of alignment.
Summary of the invention
Therefore, several purposes of the present invention and advantage provide a kind of improved cup, and it has (a) improved hot isolation performance and rigidity.It can also (b) be made by lower-cost material, (c) make more leakproof, (d) prolong shelf-life of the drink that it held, (e) be applied in microwave, (f) use the recyclable materials manufacturing, (g) by each part of most economical material manufacture with cost saving, (h) print more economically, (i) need not fold and make, and (j) adopt the high speed manufacturing machine with very fast speed assembling.More purpose and advantage will become clear by explanation and accompanying drawing subsequently.
According to one embodiment of the present of invention, thermo-insulated container is formed by single-part stationery or plastic inner cup and heat insulation overpack.Described heat insulation overpack comprises paper substrate or outer sidewall blank, selectively at a side printing and corrugated paper liner (insert).The corrugated paper liner is similar to outer sidewall blank in shape, but its size is less than the size of sidewall blank.Described liner is bonded at the middle position of the no printed side of sidewall blank, forms the double thermal insulation packing material.This double casing thing is made on the rotating cylinder and supported individual layer cup wraps up around being positioned at then, and the ripple liner part is inside and the printed side of blank is outside.Described side seam self is adhesively fixed on the interior cup.The builder can use other method that interior cup and packing material is bonding, and for example, they can use one or many low temperature glue (paste-type adhesive).They can also be at the inboard precoating polyethylene of the cutting edge of sidewall blank (or similar heat sealing material) thin layer.Then, its in packing material parcel before the cup by thermal activation immediately, and will overlapping side seam be pressed on interior glass the sidewall it be bonded in the appropriate location.

The specific embodiment
The cup of Fig. 1-prior art
Fig. 1 shows from the view of the beneath of the paper of prior art or plastic cup.Described cup comprises sidewall 10, upper limb 10R and bottom 10B, and is made by monolayer plastic or plastic coat paper.The result is that it has bad heat-proof quality.Therefore, if it accommodates the hot beverage (not shown), heat will penetrate cup and make any finger heating or scald of holding its people.Cup can be made by thermal insulation material, polystyrene foamed (EPS) for example, a kind of spumescence thick-wall materials, environmentally harmful but the EPS cup is considered to usually, because they are not biodegradable, so their use is under an embargo in some place.Also have, the builder finds to be difficult to printing trade mark and out of Memory on them.Cup can be two, but this is a way expensive and waste.Glass holder can slide on cup, but this needs extra work, time, storage and material requirements planning, and sleeve has from cup and come off and the tendency left, is inconvenient to be fit to all glass stands, and covers the pattern that is imprinted on the cup.The multilayer cup is provided out, but these cups have aforesaid a large amount of shortcoming.
If use the paper manufacturing, cup is preferably made by solid bleach sulfite (SBS) cardboard, is coated with polyethylene or any other suitable waterproof material at least one side of this cardboard.The technology of making this individual layer dixie cup is well known in the art.It has the vertical side seam (not shown) that extends to the top from bottom of cups.Combination of different materials and thickness can be used to obtain certain specific character.For example, if require heat insulation cup to have the long shelf-life, dixie cup can be at inner clad metal paper tinsel layer.Metallic paper can provide splendid moisture and oxygen isolation layer with preservation in-to-in liquid contents.Alternately, different thermoplastic material isolated materials can be covered by on the paper.For example, HDPE and EVOH can provide moisture and oxygen to isolate respectively.If require higher side wall strength, paper can be made significantly thicker.If heat insulation cup will can be used for microwave, can use to have dystectic waterproof material, for example in to high density polyethylene (HDPE).
If use the plastics manufacturing, cup does not have side seam, and can make with any material in the multiple material or the composite of material, for example PET, PP, PS and/or HDPE.The technology of making the monolayer plastic cup with thermoforming or ejection forming method is well-known.Combination of different materials and thickness can be used to obtain certain specific character.For example, if require heat insulation cup to have the long shelf-life, plastic cup can be made with the combination of HDPE and EVOH.HDPE provide water separation from, it increases with material thickness, EVOH provides the oxygen isolation.If the container that requires microwave to use can use HDPE or polypropylene, the two all is high heat-proof.Heat insulation overpack-Fig. 2 to 4
According to the present invention, I provide the heat insulation overpack for the cup use of Fig. 1.This packing material comprises substrate or thin slice 12 (Fig. 2), and it links to each other with substrate to reach liner, sheet or layer 14 (Fig. 3 A and 3B).Two sheets are of similar shape, and are generally to have four rectangles that limit the edge.Two in the edge is opposed side edge, and this lateral edges is orientated and is in acute angle, and in the edge two other is relative top margin and feather edge, for crooked shape and be oriented mutually with one heart.Layer 14 has ripple or other multiple distortion so that make its thickness thicker than the basic thickness of its material, thus, greatly increases its heat-proof quality and sets up thermal insulation layer.
For substrate 12, I preferably use solid bleach sulfite (SBS) paper at this, and thickness is that 0.20mm to 0.50mm is thick.Substrate cuts or die-cut come out from bigger initial or volume (not shown), and has along top arc or end arc and along the cut edge of every side.If the cup of finishing will have trade mark and/or other trace, substrate 12 will be from bigger initial or roll up and print before die-cut.Substrate can be that the mode carclazyte known is coated with degree of finish and the brightness of promoting print surface on printed side.
The formation of ripple liner 14 is by flat paper (is preferably put down material cardboard (platestock paperboard) or liner board; thickness is 0.15mm-0.50mm; and selectively be covered with layer of reflective material; for example film of spraymetal (metallized film) or the paper tinsel pointed out) pass belling mould or corrugating die (not shown), cut into known form then.Similar to substrate, the ripple liner has along top arc or end arc and along the cut edge of every side.I am preferably formed have tooth pitch between the 2.5mm to the 7.6mm ripple at (interval between the top of adjacent strengthening rib).The degree of depth of ripple is 0.5mm inch-1.27mm.The area of liner 14 is approximately little by 30% than the area of substrate 12.Because the size of liner is less, if it does not have precision centering on substrate, as the high speed make-up machinery was recurrent, heat insulation overpack was still available, because substrate still can extend beyond the edge of liner.
As shown in Figure 5, the heat insulation overpack of substrate 12 and ripple liner 14 or assembly wrap up the outside that heat insulation overpack is installed to the cup 10 of Fig. 1 around cup then by cup being placed on the rotating cylinder (not shown).This can finish by the automated machine of knowing.When overpack wrapped up in mode shown in Figure 5 or be crooked, the left side of internal layer or upper strata (liner 14) or right cut were cut side and will be tending towards outwards moving in skin or lower floor's (substrate 12).If described two-layer bonded on their whole zone, crooked assembly can be tending towards twisting liner, tears substrate or tear gummed connecting.Because liner 14 is not bonding along side and substrate 12, these sides can move freely, so the result that this class is not expected can not take place.
Shown in Fig. 6 A and 6B, when heat insulation overpack wrapped cup fully, the free cut edge of substrate 12 was overlapping and be bonded together.This can be with any the finishing in the several different methods.Preferably.One or many paste-type adhesives or hotmelt are coated on the overlapping edge of substrate, then force together.Alternately, can be with one deck heat-activatable adhesive, polyethylene for example is coated on the cut edge adjacent areas with substrate in advance, and then, heat-activated is with sealing the margin when imbricate and when being pressed together.Heat insulation overpack is along the vertical side seam zone of packing material, himself be bonded on the cup sidewall, this is by similar methods, and paste-type adhesive, hotmelt or precoating thermal activation polyethylene layer are coated on the inside face direct subsequently and side seam that cup is bonding.
The heat-insulated container of resulting Fig. 6 A and 6B can hold hot beverage, yet can grip with bare hand.Because the vertical banded regions of having only packing material (along side seam) and cup be by with glue bond, the therefore very small amount of adhesive of needs.Notice that the overlapping edge of substrate 12 is in contact with one another and contacts with cup 10.Because the ripple liner is shorter than substrate 12, the cut edge of ripple liner 14 does not enter between the overlapping side seam and cup 10 of substrate 12.Like this, the ripple liner can not hinder substrate 12 to bond on the cup 10.Its another advantage is to have reduced the whole thickness of the sidewall of finished thermal insulation container.If the corrugated plating with standard wraps up around cup, just have the double thickness of corrugated plating at overlapping side seam place.The additional thickness at this side seam place can hinder one in cup and be inserted in another.Have only by making substrate overlapping at the side seam place, the whole thickness of finished product cup just can not increase.In addition, be to increase stiffness and intensity, the builder can one or more peripheral positions around cup with the ripple liner and thereby heat-insulating packing material be bonded on the cup 10.
I preferably am connected heat insulation overpack on the cup 10 so that directly reserve exposed region under the edge at the cup top at this in the about 1.6mm place under the edge 10R, but packing material can be directly under the edge or separate connection further downwards.I make it not cover the whole vertical length of cup at the size of design-calculated heat insulating packaging thing.Its bottom from cup upwards separates about 1.6cm to expose the cup zone.Alternately, the size of heat insulating packaging thing can be decided to be the whole outside that covers the cup 10 except that edge 10R.The profile that also can imitate the glass holder of parcel cup is formulated the size of packing material, and the sidewall of cup can come out in the above and below of packing material thus.Packing material should be enough big with any zone that covers and therefore isolated meeting is gripped by the user.
Owing to have only substrate 12 to need, so the outside of container can easily be printed by printer.Though cup 10 should be made by waterproof material (plastics or plastic overlay paper), outer heat insulating packaging thing need not the material manufacture with this costliness, because this packing material contact liq and be not the component part of cup 10 not.
Container-the Fig. 7 that has the foamed plastic liner
As substituting of corrugated paper liner 14 (Fig. 3 A-5 and 6B), liner can be made by foamed plastic thin slice 14F, as shown in Figure 7.Thin slice 14F is preferably made by expanded polystyrene, but also can be by foamed polyethylene, foam PET (being called as PETE sometimes), or the foamed plastic (cell foamed plastic) of any other sealing or open cell is made.The thermal insulation that the foam structure of sealing cell provides is better than the structure of open cell.Therefore, I preferably use the foamed materials of sealing cell, for example exruded foams polystyrene at this.Foamer in the foam (for example carbon dioxide or butane) also can change to realize heat insulation.My preferred use can provide the foamer of fine adiathermancy.Thin slice 14F preferred thickness is 0.5mm-1.5mm.The heat-proof quality of thin slice 14F is similar to beading 14, and in some cases even better, it still can be bonding with outer-skin sheet 12 and with the mode bending identical with synusia 14.
Conclusion, development and scope
The reader it will be appreciated that in view of the above, and according to the present invention, I provide a kind of container, have improved hot isolation performance and rigidity, and it uses more cheap material, make cheaper, more leakproof, prolong the shelf-life of its liquid that holds, can be used for microwave, can be made by the renewable component of high-load more, each part all can be made to save cost by most economical material, do not need to fold, and more economical the printing.Can obtain heat-insulating cup around monolayer plastic cup parcel heat insulating packaging thing, the plastic material of cup in it depends on, it can be leakproof, shelf-life with prolongation, can be used for microwave, for plastic cup provides rigidity, for plastic cup provides better pattern, and potentially can be than wrapping up heat insulating packaging thing more cheap (depending on the type of plastic material and used thickness) around the individual layer dixie cup.Because substrate overlapping, thermal insulation layer can not hinder substrate and self bonding or bonding with cup.
Though top description comprises many special characteristics, should not think that they limit the scope of the present invention, and should regard the example of its present preferred implementation as.A lot of other developments and variation all are possible within teachings of the present invention.For example, though optional, insulation blanket, heat insulating packaging thing just also can be bonding at the sidewall of one or more positions and interior cup, because this can provide bigger rigidity to the finished product cup.Heat insulation overpack is wound in the cylinder and is bonded into this structure, then cup is inserted in the packing material.As substituting of ripple, the liner mold pressing can be gone out indenture, horizontal ripple, criss-cross projection etc.As already mentioned, spacer block can selectively apply reflex-reflective material, the film of metallic paper or coating metal for example, and it can be positioned to cup in the radiant heat energy reflected back.Equally, substrate 12 (also can be or replace liner 14) also can extrude convex epirelief, make ripple or made by foamed plastic, so that provide appearance of fabrics and sensation and extra heat-proof quality for the outside of cup wrapper.Can also or can be coated in polyethylene (or the similarly heat sealing material) thin layer of substrate cutting side in advance by one or many low temperature glue (paste-type adhesive), in packing material is bonded on the cup.Then, with packing material before the interior cup parcel, immediately with polyethylene (or similarly heat sealing material) thin layer thermal activation, and on the sidewall in will overlapping side seam being pressed in glass so that it is bonded in the appropriate location.Because interior cup and heat insulating packaging thing can be made by different materials,, comprise that the carclazyte that is used to improve print surface is coated with renewable paper so substrate and/or ripple liner can be made by renewable paper.Described cup can be used for holding heat or cold solid and liquid.Substrate and insulation blanket can have difformity, and for example, if cup is not tapered, the relative edge of substrate and liner can be parallel.
Therefore, scope of the present invention should be determined by claims and jural equivalent thereof, rather than be determined by given example.
