Description

Tubular container with outer tube and internal container

Technical field

The present invention relates to a kind of tubular containers being fabricated from a flexible material, for accommodating cosmetics, food, drug etc., more Specifically, being related to a kind of tubular container including outer tube and the internal container being contained in outer tube.

Background technique

Flexible plastic pipe is widely used in cosmetics, pharmacy or food service industry.Flexible plastic pipe is characterized in that It is intended to accommodate the hollow body of product (for example, cosmetics cream) or skirt section and is placed on the one end in skirt section and is intended to permit Perhaps the discharge of product or quantitative head.Head can be equipped with for providing the neck, cap and quantitative machine of outlet for product Structure etc..Once the pipe is already filled with product, the end opposite with head in skirt section (generally passes through heat by welding of conducting heat Wind, hot clamping, ultrasonic wave etc.) it is sealed.

These flexible plastic pipes are obtained by various manufacturing methods, such as extrusion, coextrusion, injection molding etc..Equally, A variety of methods are known, by including text directly on flexible plastic pipe or by being incorporated to an individual element (such as label) Thus sheet, figure, pattern etc. provide any information element or decorative element for flexible plastic pipe.For example, flexible plastic pipe can be with Using such as offset printing, flexible version printing, serigraphy, stamp, the technologies such as self-adhesive label are decorated.In injection molding tube manufacturing process, The technology of referred to as in-mold label (IML) is well-known in the prior art to provide the technology of label for pipe.

Although market is widely used, there are some yet unresolved issues for the manufacture of flexible plastic pipe.

For example, first problem is to be difficult to the manufacture material of selecting pipe, especially in Shooting Technique.Used material Material must have very special characteristic, and satisfaction can such as process, have solderability appropriate, impermeability, resistance to environment The requirement of stress cracking resistance (ESCR) etc..When being related to food industry, material must also meet relevant to food touch-safe It is strict with, because pipe in the market must directly be contacted with packaging product.In cosmetics, nutrition and area of pharmacology, material Must satisfy the requirement of specific applicability, such as nontoxic, comprehensive migration and specific transfer etc. because the pipe must often with will quilt Intake or the product that be applied on body directly contact.In general, by selecting and using polymer compound and other components It realizes these characteristics and meets these requirements, especially through the pipe of injection molding manufacture.However, meeting various want The acquisition for seeking the polymerizable compound (including mechanical requirements, food contact requirements, non-toxicity requirements, machinability requirement etc.) is extremely Complicated and expensive.It must also supplement, it is basic due to the polymer that includes in compound when using polymerizable compound The allowance of variable (mobility, density, rigidity etc.) maintains and guarantees that the property of the compound is complicated.Therefore, can The acquisition for balancing the polymer of all properties needed for successfully manufacturing and using the pipe is extremely complex, is being especially injection molding when pipe Guan Shi.It is directly eliminated much in addition, obtaining and meeting the voluntary of polymerizable compound that stringent food contact or non-toxic require Application of the polymer in prepare compound, this further hinders the design of polymerizable compound.

Second Problem is related to a kind of pipe well known in the prior art, is actually made of two pipes, one of them In another.Make solution of the pipe in another pipe commonly used in obtaining without air vessel, that is, prevents air from entering To improve the preservation of packaging product (for example, such as not product, Essence of cream of additive etc, dimension in the container Raw element C etc.) container.The influence that pipe collapses when the solution is also commonly used for solving to use.Hold in such tubulose In device, inner and outer tubes are equipped with skirt section and the head with mouth neck portion out.Inner and outer tubes go out mouth neck portion connection by it.It should Solution existing defects in terms of obtaining high reduction rate (ability for transferring out all the elements object of pipe), because due to inner tube The high-caliber rigidity on head prevents the pipe from collapsing completely.

Third problem is related to the sealing of two-tube tubular container, such as container those of is mentioned in the last period, or such as double (tubular container being made of inner and outer tubes, the tubular container accommodate two different products to product container, and middle external tube has Head, the head have the particular arrangement of two delivery outlets for two kinds of products, so that two kinds of products are in the standard for applying them The true time discharges and mixes simultaneously).Assembling for above-mentioned two-tube container, the skirt section of inner tube and the skirt section of outer tube have Significant diameter difference, so as to which inner tube is assembled in outer tube.It means that when the end in the skirt section is between them In conjunction with sealing and when flattening, can not achieve the perfect sealing between the skirt section of inner tube and the skirt section of outer tube, to seal Defect.More specifically, in central area, there are four wall thickness for sealing tool, and side only there are two.In compression clamp, With correct pressure welding wall in region of the tool there are four wall, and the insufficient pressure in the region of two walls, cause at two Failure welding in the region of wall.In addition, this loosening hinders the introducing of welding tip, which must be non-in pipe Often accurately adjust.

The present invention is intended to provide a kind of new tubular container design, at least one to solve the above problems.

Summary of the invention

The object of the present invention is to provide a kind of pipes for being used to accommodate cosmetics, food, drug etc. being fabricated from a flexible material Shape container, and the method for the manufacture flexible tubular container.Tubular container includes outer tube and internal container.Outer tube includes skirt section And head, wherein head generallys include neck, screw thread etc..Internal container is then equipped with skirt section, and in preferred reality of the invention It applies in example, is further equipped with the shoulder in the proximal end in the skirt section of the internal container.Shoulder is unlimited cap, i.e., with aperture Cap, therefore the proximal end in the skirt section of not completely closed internal container.The shoulder is flexible or deformable, preferably presentation plasticity change Shape.Internal container is contained in outer tube, and the shoulder of internal container is preferably sealingly fixed to the head of outer tube Inside, once so that the proximal end of tubular container has sealed, the shoulder of internal container can provide Fluid Sealing for internal container Property.Therefore, internal container does not have the tube head (having neck, screw thread etc.) of typical conventional flex pipe, on the contrary, outer being welded to Its content is discharged using the neck on the head of outer tube, screw thread etc. for Guan Shi, internal container.In other words, internal container shares The neck on the head of outer tube or the neck on the head using outer tube.In addition, shoulder preferably has high deformability, without damaging The welding on the head of evil shoulder and internal container.In addition, shoulder preferably by with the same or similar layer in the skirt section of internal container Pressure composite material (aluminium or other materials) is made, show cost advantage and very high deformability (deformation be plasticity and And therefore avoid shape from restoring and guarantee permanently collapsing for internal container).

Gap is limited between internal container and outer tube.Preferably, tubular container after use (or, in other words, After pressing tubular container is to remove the product being accommodated within) its original-shape can be restored.On the other hand, internal container is excellent Selection of land keeps deforming by check valve, which prevents air back to the inside of internal container.Preferably, which puts Set cap in the head of outer tube, fixed to outer tube head or in another component such as medicator or pump.In addition, internal The distal end of container preferably deforms and widens (or extending to the outside), so that it is neighbouring with the distal end of outer tube and contact.Outer tube and interior Portion's container can be made from a variety of materials, so that being intended to meet and the function with the internal container that the product of packaging is kept in contact Relevant requirement, and externally visible outer tube is kept not need the requirement for meeting internal container, but meet and outer tube function The relevant requirement of energy, these outer tube functions are, for example, to carry one or more decoration elements, label etc..

Meet difference by the material of at least some of the embodiment of the present invention and especially outer tube and internal container to want Initial advantage provided by the embodiment asked is a simplified the selection of material.This solves a main problem of injection molding tube, and And solve extruding pipe and other pipe manufacturing technologies for needing to use the material with high request and performance to a certain extent.Example Such as, it now is possible to which selection uses recycling and reusing material, especially for manufacturing outer tube, because can guarantee these recycling now Recycle material will not with packaging product contact, therefore tubular container can meet currently with food, pharmacy or cosmetics department Packaging relevant legislation.

It is by another advantage that at least some embodiments of the invention provide, and does not for example include double in the present invention The traditional injection moulding pipe of tubing type is compared, it can reduce the thickness of outer tube, because outer tube of the invention only has mechanical function, and And it does not need to contact with packaging product.If fruit product is contacted with external container, then this thickness reduction is impossible, because its Permeability will receive influence.By the way that with lesser wall thickness, container will have more permeability, therefore cannot suitably protect and be contained in Product therein.Therefore, some product compositions may permeate, and the characteristic of product may change.In the present invention, tubulose holds Impermeability needed for device can be provided by internal container, and internal container can be by laminated material (laminar composite) --- lamination material Material includes aluminium film or polymer barrier layer --- and it is made or is simply made of the single layer structure with necessary impermeability, The permeability of middle external tube is inessential.The reduction of the thickness of lower wall is also impossible the injection molding tube the case where, because this Kind, which reduces, will significantly affect the complexity well filled for obtaining injection molding cavity.In order to solve such case, in plastic injection field In the known polymer using higher mobility can manufacture the product with thinner walls, however, this increase of mobility is logical Often need to change key performance, such as environment resistant stress fracture ability (ESCR) resistance.

By at least some embodiments of the invention and especially wherein tubular container restore its outer shape after use Embodiment provided by another advantage is that, tubular container provides better ergonomics and uses.This is because in order to The product of storage is extracted, pressure will be applied to always on the tubular container of expansion, i.e., is shaped as being completely filled at it Container on, so that the hand of user be made more comfortably to operate.Another advantage of these embodiments is that tubular container can be kept Constant appearance, although i.e. Reusability tubular container still can be kept such as new appearance, therefore can be entire at it Optimal appearance is kept during service life.Even if tubular container be in those airfree embodiments be also in this way, because Internal container keeps deformation while outer tube restores its original-shape.

By the shoulder of at least some embodiments and especially internal container of the invention in the internal head for being fixed to outer tube It is another advantage of provided by the embodiment in portion, two heads of head and two of them pipe is all had with wherein each pipe The two-tube solution of tradition being assembled with each other is compared, and obtain between two pipes more effective and more durable consolidates It is fixed.In addition, compared with two of them pipe is by the fixed two-tube solution of tradition in its respective head, these embodiments Also improve reduction rate.The raising of this reduction rate is since existing solution does not allow the entire of the head of internal container It collapses or almost entirely collapses, even if the thickness on the head of internal container is fabricated to the head less than outer tube；On the contrary, in the present invention Tubular container in, the shoulder of internal container is flexible, and preferably by laminated plastic or metal-plastic composite material system At, and it is welded to the inside of outer tube head, since the flexibility of shoulder is so as to collapse.

Widened by the distal end of at least some embodiments of the invention and especially wherein internal container and with outer tube It is another advantage of provided by distally neighbouring and contact embodiment, the sealing of the distal end of tubular container significantly improves.
