Detailed description of the invention
In order to be illustrated more clearly in the utility model, below in conjunction with preferred embodiments and drawings, the utility model is described further.Parts similar in accompanying drawing represent with identical Reference numeral.It will be appreciated by those skilled in the art that specifically described content is illustrative and nonrestrictive below, protection domain of the present utility model should do not limited with this.
Embodiment 1
As Figure 1-Figure 2, have an easily tore film plastic cup for profile seal bulge loop, described plastic cup comprises cup 1 and epiphragma, and the described rim of a cup of cup 1 and sealing place of epiphragma are provided with and seal bulge loop 2, the height of described sealing bulge loop 2 is higher than rim of a cup plane, and described sealing bulge loop 2 is provided with directed wedge angle 21.
Described sealing bulge loop 2 is ring-type curvilinear structures.
The rim of a cup of described cup 1 is quadrilateral structure, and the sealing bulge loop 2 that in four angles of described rim of a cup quadrangle, at least one angle is corresponding is provided with directed wedge angle 21.
Embodiment 2
As different from Example 1, the rim of a cup of described cup 1 is circular configuration, and the sealing bulge loop 2 that described rim of a cup is corresponding is provided with at least one directed wedge angle 21.
This utility model is mainly for the two class problems that current cup series products is ubiquitous: when 1) using, epiphragma is difficult to peel off from cup, affects client and uses; 2) simultaneously current existing so-called easy-to-tear film lid material (using easy-to-tear film technology based on European & American Market) due to sealing intensity too low, easily occur run-down in storage and transport process, and be not suitable for progressively being tending towards harsh domestic trade accumulating condition.Overcome the above problems, this just needs the design of the stripping dynamics of tearing of epiphragma in the scope that staff easily tears, still keep certain sealing intensity may seal to product the injury brought to resist in storage and transport process simultaneously, both demands are taken into account, both successfully solve the convenient problem peeled off of epiphragma, still possess higher sealing intensity to meet the demand of transit link simultaneously.
As shown in Figure 3 and Figure 4, a is circular arc seal ring, and b is seal ring, and c is wedge angle seal ring, and d maximumly tears stripping width, and e tears stripping force direction.Research user staff tears extract operation mode, be example for square cup, namely from four epiphragma complementary angles of sealing, get to tear angular direction after clamping epiphragma (circle cup is to reserve and tears angular direction), and because this direction sealed width is maximum, now user needs to pay maximum stripping power of tearing (namely opening tearing force), so namely determined and tears stripping force direction and maximum dynamics region.Set out with this, structurally build orientation and tear stripping structure, as Fig. 4 changes former circular arc seal ring into directed wedge angle in four angular direction, reduce power sealed width upwards, tear stripping power (namely the maximum of user tears stripping power) like this in this direction and be greatly reduced.
Epiphragma sealing intensity is not done to reduce and is changed simultaneously, still choose the higher epiphragma of sealing intensity as lid material, research is known in storage and transport process, general seal break-off reason is that the cup of packaging product is squeezed distortion, inherent express material cup and epiphragma is caused to be tightly connected region, finally " squeeze " and open sealing and cause run-down, and this power of " squeezing " be by outer pressure pressure change into liquid material internal pressure and for sealing lip, the tangent line vertical direction that its stepless action is often put in sealing lip, this that is to say that the cause run-down limit and the cup film sealing intensity of bright transportation are closely related, and this structure can't affect the change of sealing intensity, low like this opens tearing force and selects high sealing intensity just to take into account the needs easily tearing and use transportation protection.
As shown in Figure 3, stripping maximum width tears about in fillet seal place: 15mm, as shown in Figure 4, the stripping maximum width that tears of wedge angle sealing place is about 5mm, theory calculate is maximum tears stripping power: tear stripping power=tear stripping intensity (bond strength) x and tear stripping width, suppose that sealing intensity is 12N/15mm, then what angle arc sealed tears stripping power: 12N/15mmx15mm=12N; What wedge angle sealed tears stripping power: 12N/15mmx5mm=4N.Conclusion: during wedge angle unseal, maximum stripping power of tearing about reduces by 2/3.
Tear stripping operating process according to staff, open tear after continue tearing force will carry out along seal ring direction, at this moment the width of seal ring own by determine need tear stripping power, the narrower stripping power of tearing of ring width is less.Narrower line seal ring, causing the bullet of cup to become when sealing due to pressure, more will can make the part involution of seal ring side, brings extra sealing to cause tearing stripping power and improves, so just limit the constriction of ring width.For head it off, line seal ring in order to curve form, should be occupied seal cavity, improve cup ring portion elastic strength, raising distortion is withstand voltage simultaneously, thus solves remaining limit by the problem of sealing, obtain carefully sealing loop wire clearly, thus make this section tear stripping power can adjustedly to control.
There is the plastic cup of profile seal bulge loop, after production is filling, in cup and epiphragma seal process, temperature requiredly to be reduced, thus decrease the consumption of electric energy, for PS cup material and EVA underseal film, seal temperature is reduced to 130 degree by 180, will bring very big energy conservation according to product yield.And due to the elasticity that sealing bulge loop has, the heat-resisting special fluororubber pad on heated sealed plate can be saved, save this expensive consumable material.When producing filling, the intrusion pipe of basic equipment all may have residual extension of sauce and drip, especially the product that viscosity is higher is more serious, when material drippage pollutes in sealing place, after the cup of face seal ring and epiphragma seal, material clamp forms false envelope between cup film, thus can seepage be caused, this situation for planar sealer for face seal ring, it is the defect that cannot at all eliminate, use the plastic cup with profile seal bulge loop then effectively can cut off pollutants, ensure good sealing, address this problem at all.
The plastic cup with profile seal bulge loop of the present utility model tries through each pacing, and testing setup target is reached in every test, to comprise in production sealing test after in fact mechanical irrigation note material, easy-to-rupture is tested, run-down test after long distance transportation after the packing of product, and the market user of bulk article uses easy-to-rupture to reflect test.
First in reality perfusion is produced, cup of the present utility model (cup is with 5x4 disjunctor form) is used to put into perfusion manufacturing line, now the heat-resisting teflon rubber sheet gasket needed during general cup sealing can be pulled down, temperature controller temperature setting downward 50 degrees centigrade simultaneously heated by heat-sealing temperature, can pour into and and diaphragm seal after actual temperature is stable.In production process, on-line operation personnel are reflected, remove from and need after timing replacing heating cushion, to improve the comfort level of work efficiency and work under high-temperature situation, and possible high temperature injury; The reduction of seal temperature simultaneously, the heat balance of equipment heater section is comparatively fast reached, and fluctuating range obviously reduces, product sealing intensity is more even.
Online QC checks product, owing to sealing the buffer action of bulge loop, causes the product of poor sealing almost no longer to occur by material drippage pollutes.After sealing, product detects through extracting, and tears strip off and opens dynamics and comparatively previously greatly reduced, and through many places sensory testing, in different crowd (except infant), tears across journey staff and tears in the scope that stripping sensation dynamics is suitable for opening; Continuing afterwards tears stripping process, and effort even, can peel off whole epiphragma from cup easily, thus easy to use.
For the experiment of easily tore film plastic cup in transport with profile seal bulge loop of the present utility model, product after In Guangzhou Area (temperature in degree Celsius about 25 degree) packaging is cased according to the universal product (50 glasss of/layer of x5 layer), 8 casees/layer x8 layer is stacked in study plot platen, carry out long-distance transport, warp is from Guangzhou to Shenyang Automobile Transportation, be stored in-15 degrees Celsius of warehouses and place after 48 hours, comprehensive OOBA (out of box audit), through checking product in the carton of different number of plies diverse location comprehensively, cup sealing is intact, occur without run-down phenomenon, normal domestic trade accumulating condition is accommodated completely after showing the sealing of this structure cup, and sealing adapts to temperature traverse on a large scale.
For user, the product of this cup packaging uses in different cities catering market, and through passive observations user situation, insentience difficulty tears the situation complaint of use, and this and existing cup receive difficulty successively to tear complaint situation obviously different.
It should be noted that; there is the equipment of bulge loop structure heats sealer; its temperature booster bulge loop adopts the design of this wedge angle seal ring structure can achieve the above object equally, therefore also belongs in the scope of technology point protection by the design of this wedge angle seal ring structure on temperature booster sealing bulge loop.
Obviously; above-described embodiment of the present utility model is only for the utility model example is clearly described; and be not the restriction to embodiment of the present utility model; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here cannot give exhaustive to all embodiments, every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
