Description
Technical field
The present invention relates to a kind of improved height damp proof packing that is used for food or non-food stuff, relate in particular to a kind of leakproof tank that is used to pack to the solid-state food of humidity and oxygen sensitivity, this container can stand multiple atmospheric conditions, and the beneficial effect of environment aspect, total manufacturing cost aspect and manufacture method aspect is provided.
More particularly, the present invention relates to a kind of improved leakproof tank, this container is used to pack for example frangible food of solid-state food to humidity and oxygen sensitivity, for example the potato fast food of potato chips, processing and nut etc.This container comprises the tubular body made from composite material, and this tubular body comprises that an external skin, at least one external card (paper) plate (cardboard) layer, cover the heat sealable internal coating of a clamp layer in-to-in oxygen barrier layer and a thermoplastic material; The sealing arrangement of one peelable sealing film form, the sealing device comprises the internal coating of an oxygen barrier layer and a heat sealable thermoplastic material; With a profound bottom of making by composite material, this bottom comprises that an over lacquer layer, at least one clamp layer, cover the internal coating of a clamp layer in-to-in oxygen barrier layer and a heat sealable thermoplastic material, bottom and edge thereof upwards and outwards stretch and surpass the tubular body end face, and are heat-sealed to the inside and outside of described tubular body.
Background technology
Such leakproof tank is well-known.
For example US Patent 3,973,719 and 3,988,185 disclose a container assemblies, and this container assemblies comprises the composite tube body with an outside roll extrusion top margin, and tubular body has an asymmetric sheet film type sealing arrangement sealing and is fixed in roll extrusion edge and metal bottom, come metal is sealed by the bottom end that is crimped to tubular body, above-mentioned patent discloses its manufacture method simultaneously.Yet, because the bottom of this container assemblies is a metal, a lot of difficult problems are proposed for relevant manufacturing, weight, cost and recycle, therefore this container assemblies and unsatisfactory.
The such existing clad vessel of appreciiable typically utilizes well-known suturing skill (double seaming) airtight by metal end in a side on the market.But, because metal end accounts for the major part of the whole weight of container, so needs energy big in the manufacturing process, and produce a large amount of radiation.And in many countries, based on the consideration of recycling, metal end need separate with other parts of packing, and this causes user and waste recovery to utilize the inconvenience of mechanism.
As everyone knows, such metal end or bottom have been limited this kind packing and can not be used for micro-wave oven.For making it possible to add the heat-sealing product in container itself, thereby convenient user and can expand the range of use of these kinds packings should replace with metal end the material of anti-microwave.
For overcome these problems as far as possible; EP-A-0 352 127 discloses a kind of oxygen barrier layer laminated structure; be applicable to the ne-leakage container of impermeable oxygen; this container comprises the structural matrix with mechanical stability; heat sealable polymeric material skin; filleting polymer resin ground floor; the oxygen barrier material (comprising aluminium foil) that can in greater range of materials, select; has extrusion coating protection and can inner heat-sealing and the polymeric material that can contact with product; and the second filleting polymer interlayers; the polymer resin layer of anti-unreasonable use; the 3rd filleting polymer resin is all with this order coextru-lamination on the inside face of oxygen barrier material layer.But, the heat sealable polymeric material skin of its use has defective, because this material the time often decolours and misplaces in heat-sealing, that is is adhered on the heat seal tool, and this instrument is used to and reaches the required lead aircraft tool cycle and under the necessary hot conditions.
Described a kind of compound end sealing element that is used for clad vessel in GB-A-2 176 457 patents, its body comprises at least one wild card flaggy, and one is covered in in-to-in equally intercepts paper tinsel (as aluminium foil), an inner sealable plasticity capping.The sealing arrangement of sealing element comprises an optional layer of tearing with inner salable plasticity capping, the profound bottom that the sealing parts are prepared, after filling, comprise that at least one clamp layer, a metal intercept paper tinsel and place its interior salable plasticity capping, this bottom and its edge upwards and outwards stretch and surpass the tubular body end face, portion seals with outside and described tubular body within it, wherein bottom metal intercepts paper tinsel and is arranged in clamp layer inside, itself be positioned at plasticity capping the same side, wherein should bottom and tubular body sealing by high-frequency induction.
Statement of requirement carries out diathermic heating and compare to the identical Machine cycle of known vessel with sheet tin bottom to provide in the course of processing.When use one comprises that bottom, the metal obstruct paper tinsel and of at least one clamp layer place its in-to-in sealing plasticity capping, it also specifically refers to seal by the heat of only being supplied with by the outside, therefore be not to provide by high-frequency induction, high-frequency induction only is used for the unsafty situation of long period.
But, utilize electronic heating that this compound bottom sealing arrangement is sealed not only machine and operating cost and unsatisfactory, and it requires to intercept paper tinsel and have certain thickness, this has limited its essential variation.
And, surpass the tubular body end face when upwards and outwards stretching, when this compound end seal assembly is connected with the pipe portion of tubular body, intercepts paper tinsel and can produce pin hole, otch or breach by bottom margin, this causes container to lose its leakproofness, thereby makes barrier properties invalid.This brings a particular problem when packing solid friable food product, and friable food product not only is easy to go bad under the humidity effect, and will degrade when aerobic exists, and therefore intercepts paper tinsel if produce pin hole, otch or breach, will cause product seriously rotten in storage process.When packaged products is transported under the different pressures condition, this influence will increase, this is to increase owing to the bigger climatic conditions of variation will make internal tank contact with surrounding environment, and these climatic conditions comprise for example high temperature and low temperature, high humidity and low humidity, high height above sea level and low height above sea level.Such condition can cause tangible container external and internal pressure poor.Since this pressure, container material, barrier layer will be under pressure then, and this pressure may be very big so that form pin hole or breach, or exist under the situation of pin hole or breach after the processing, causes this perforation to increase, thereby make its barrier properties of packing forfeiture.
And because sealing characteristics is packaged in high altitude region and can has high interior the pressure, this may cause packing to be heaved.The shape that depends on packing, this outside heave can cause being packaged in be unstable state (as swinging and shake) on the shelf, thereby whether the user is bought this product have a negative impact.
In addition, the existing composite material that is used to process this clad vessel and bottom also must have following characteristic: allow the lead aircraft device cycle, this cycle comprise with sheet form provide and transmit composite materials to and time of passing machine, this machine is used for cutting, deep-draw and transports compound bottom etc.; The requirement material can bear this condition and can not cause machine run to be interrupted, and interruption can make composite laminates adhesion or slippage cause because of the thermoplastic material external coating.
In addition, after the cutting bottom, the surplus material of composite material (being so-called knitmesh) need be transferred among the cutting equipment and/or outside, in this transmission course, the composite material that is used to form tubular tubular body often easily breaks, and causes obstruction, thereby influences the reliability of system.
Equally, the forming process in compound bottom is also included within the transmission course, and friction is important factor.Friction is excessive in (the being deep-draw) process that is shaped causes barrier layer to break or produces pin hole.Also depend on employed transmission system such as air transfer, excessive the causing of finding to rub stops up.In heat-seal operation, need material is folded, and with net shape heating and pressurization, so that should packing shaping and sealing.The excessive material that causes of friction outer and that heat between the back part is folding improper with sealing, thus perturbation operation and leak free quality and reliability.On the other hand, the young pathbreaker that rubbed is because composite material can go wrong from the machine part slippage that is used for it is processed, and this also can cause the course of processing to be interrupted, and especially makes us being difficult to accepting when the machine cycle of operation is short.
And, only using the outside heat that provides to carry out in the process of heat-seal operation, material may decolour, even produces the burning trace on the resinous coat outside, is necessary to protect the container skin not to be subjected to invasions such as humidity, dust, and its skin can be printed user profile.But, in dispensing, storage and the use of this container, importantly container can bear the humidity of certain magnitude, and stops it to draw the dirt dust, and this is necessary for acceptance level that improves the user and user's comfort feature.
Summary of the invention
