Abstract

An aperture forming structure includes a break away tip member (634) of thermoformable plastic. The break away tip includes a hollow protrusion extending from a surface. The intersection of the hollow protrusion and the surface is a fault line (636). Rupturing of the fault line creates an aperture for dispensing the contents of the package. A cap (620) may be integrally formed with the aperture forming structure and detached for protecting the hollow protrusion or for closing the aperture. The aperture forming structure can be made by heating a relatively stiff substantially flat thermoformable sheet of and then stretching the sheet to create a first and a second hollow protrusion in tiered configuration. A rupture line is placed at the intersection of the first and the second protrusions. The sheet may be attached to a pouch or containment member formed from a flexible sheet which contains any flowable substance.

Description

The delivery port shaped structure of the Bistributor package of Reclosable, Reclosable and the method and apparatus of making this structure
The preceence that this world application requires be submitted on January 23rd, 1996 the 60/010th, No. 455 U.S. Provisional Applications, and the same position contriver of instant non-provisional application is that submit on January 3rd, 1997, the U.S. Provisional Application that is entitled as " the delivery port shaped structure of the Bistributor package of Reclosable, Reclosable and the method and apparatus of making this structure ", and these two applications are all quoted for referencial use at this.
FIELD OF THE INVENTION
(self-contained) that the present invention relates to be easy to open, provide for oneself, easy to use, once or high-speed production and that make by a material that can reuse the on a large scale again Bistributor package of nonexpondable and economy.They can hold product and many other products such as syrup, cream, cheese, salad dressing, shampoo, hand frost, liquid detergent, motor oil, toothpaste slurry, pet food.The invention still further relates to a kind of packing, this packing can be with the product that is held, for example mouthwash, cough syrup, confection, alcoholic drink etc. directly are assigned in user's the mouth, and having a cap of Reclosable that forms an integral part of packing, this cap preferably links band (tether) and this packing links mutually by same and a packing is integrally formed.Also as can be seen, the cap that has Reclosable may be separately formed with the parts that are easy to open (feature) that link band, and sealing-in or be bonded to many packings, such as on bag, milk container, box, mat (pillow) the packing packaged surface such as (sachet (sachet)), so that high efficiency, low cost ground manufacturing distribution package or squeeze bag.These extruding sack-type packagings can distribute the food paste such as pet food, cream, grease, yogurt, certain type the frosting compound of living face, cake, and are made by the laminate or the co-extrusion casting die of the cardboard plastic tab of handling, applied, paper tinsel, these materials.The device that be easy to open of the application in its preferred embodiment is made up of a drum type projection, protrudes a second stage conical butt projection from this part and also extends to form a top, centers on a dislocation line in the bottom on top.Make this top fracture to form the hole by applying slight side direction finger pressure.In order to protect this separate top, also can approach dual projection and form a cap that is linking in shipment or during sealing this hole again.This links function not only can keep this cap, thereby prevents its loss, but also plays the effect of spring, so that this cap is kept going up in position (on the top).
In the formation system of the hole of another kind of form, initial drum type projection is replacing the conical butt separate top, one dislocation line figure (pattern) is formed in its top surface, be designed to expose instrument/stopple when being pressed into this dislocation line figure when one, this dislocation line can disconnect to form the delivery port of various required forms.Can form this instrument/stopple of exposing replacing cap, and this exposes instrument/stopple and can linked, perhaps cap can have two ends, has a cap on the end, and have the instrument of exposing/stopple structure on the other end.Also can see, hold the cap of projection that one is formed in the cap, is similar to colored shape when this cap is crushed on the drum type projection, will play the effect of a central hole device.Can see further that also in some cases, for example the packing of the flowable product of alcoholic drink and so on needs under the situation of layer of metal paper tinsel lining, this drum type projection can be replaced by a kind of pier shape projection with a center dislocation line figure.The reason of assigning to replace the drum type projection with this pier shape salient is to prevent that this paper tinsel layer from extending in surperficial confluce exceeds its elastic limit, to such an extent as to rupture at shaping.Described figure can be washed open by an instrument/stopple of exposing that is shaped, this instrument of exposing/stopple thermoformable, and be tied to the unit or make separately, and this links band and can have an annulus that is shaped at its free end, and this is exposed instrument/stopple and can be placed in this annulus.
The invention still further relates to a kind of at high speed that is used for and make the method and apparatus of said structure and packing reliably, in many cases by the material that can reuse fully, thereby make this packing, and can reuse in many cases with the low cost manufacturing.In addition, compare with the packing of other previously known part of great majority, this packing can be used less plastics, even also can reduce resource consumption and help environmental protection when adopting the material of not reproducible utilization.
The background of invention
Carried out multiple trial so that a kind of Bistributor package to be provided, a kind of product is contained in wherein with required standard volume, use for one or many, and the product that is held can distribute from this packing.
One type of this Bistributor package is pad bag (pillow pouch) or a sachet, is generally made by the relatively thin plastics and the composite of paper tinsel or laminated plastics and paper tinsel.These packings often are used as the container of the residential care preparation catsup (catsup), mustard seed, other seasonings, agent (conditioner) in hair is transferred, coloring agent and the emulsion (creme) etc.Though such packing is widely used, the user generally dislikes this type of packing simultaneously.For near built-in substance, this bag must be held in a hand, provide one to tear action and application force with the another hand simultaneously.Form initial tearing with the sealing that destroys packing difficulty normally, this often needs the assistance of user's tooth.In addition, in case formed initial tearing, the paper tinsel of lamination and/or plastics are not only often torn in a kind of uncontrollable mode, and hand applied holds pressure and often force built-in substance not only before the user prepares to use this built-in substance but also even tear action at this and shift out this Package casing before finishing by of user.Open these packings and can cause that fidgety mood (frayedtemper), nail rupture, tooth is cracked and other problem.The user must use two hands can open this container simultaneously.This will open these packings and be practically impossible for disabled person, arthritic and other impaired person.Another problem relevant with these existing packings is that these packings can't be sealed by actv. again, thereby makes this packing can't repeated use, and so wasted also untapped built-in substance.Other shortcoming comprises because the flow direction of the uncontrollable liquid such as coffee cream, mouthwash or alcoholic drink from this packing of the opening torn, so sachet can not hold these low viscosity product effectively.These packings also generally can't reuse fully, and therefore become environmental contaminants.Yet as mentioned above, if these sachets are preferably continued to use, the parts that are easy to open of this application can make things convenient for and be bonded to sachet economically, so that make the packing of a high degree of isolation that be easy to open, Reclosable.
Another kind of Bistributor package is the cup that tears the top off that is used for cream, margarine, syrup, baste, salad dressing and other similar products.Such packing needs good eyesight and M/C skill.This packing often is used as coffee cream device (creamer), and has many shortcomings, comprising: be difficult to tear the top off and open this packing, and be difficult to pour out built-in substance, spill unexpectedly, to such an extent as to and can not seal again can't repeated use.The present invention as described herein can be bonded to or integral body is formed up in these packings, so that these packings can be opened easily and sealing again.The Bistributor package that also has another kind of type is the unencapsulated corrugated paper packing that is used for salt and/or pepper, in a single day this wrapper just forms an opening along an intermittent line bending that runs through this ripple cut-out, and the salt or other material that are contained in this packing can flow out by this opening.These packings are only distributed with the solid of the flowable drying of action of gravity, and can not be used to hold and distribute " wetting " or liquid flowable materials.Packing of the present invention can be held and dispense liquid and dried particulate product simply.
Less and the expensive bottle that metal cap is arranged is used for alcoholic drink, and can pour out or directly enjoy in bottle.These bottle Reclosables, but their volume often is made into and only is used for once drinking, so they need not seal again.This instant packing can be used for the alcoholic drink for the part of bottle cost.
Anyone is familiar with the milk carton of ubiquitous gable-top, and anyone is familiar with all difficulties degree when opening them.These comprise from the nail fracture until just can't open this carton simply without pocket knife or other instrument.
They are sealing again veritably never, and looks in disorder and unclean at the worst.In the U.S., existing a kind of like this trend is promptly installed a kind of stubborn cap combination, and this combination comprises that one engraves the nozzle member of screw thread, and this nozzle member is sealed on one of them of oblique triangle of carton, and another be one not bonded assembly twist cap.The making and the cost of installation of this small-sized injection molding two parts (duo) are too high, may be about 3 to 5 cents, and are commonly used in the gable-top juice container of bigger pottle dress.These are costliness and high profit article, and each needs about three dollars, and can bear the extra usage charges of the delivery port that is used to screw on.Yet, sell hundreds of millions such gable-top packing boxes that are used for milk and cream every year, its volume changes between the pottle at half pint.Yet maker is unwilling to increase widely the carton cost, and the carton that is difficult to open is used in popular continuation.
This instant invention can form a kind of delivery port that significantly has a cap that is linking that seals and tamp, this delivery port and cap are formed in the less plastic unit of a mono-, can seal simply or be bonded on the triangle that is positioned at above down the pre-manufactured hole.Its manufacturing cost is extremely low, and is made by polypropylene, high density polyethylene (HDPE), PVC (polyvinylchloride (polyvinyl chloride)), polyester etc., and it has only utilized cost to be several material at zero point.As seen, this cap has dual purpose.It can make delivery port Reclosable after opening, and it is also important that, owing to this cap was placed on the separate top between Time of Shipment, so this cap is being protected the top, in order to avoid its accident ruptures or is subjected to any application force of opening this delivery port.
As seen, the lower drum type structure that is positioned at the separate top below can be elongate, and when disconnecting with convenient top, an elongated nozzle can make flowable materials directly be inhaled into from container, be under the situation of motor oil perhaps, can directly it be circulated in the engine oil input port at this material.Another shortcoming of current distribution package is the sealing of outlet opening.The outlet opening of closed tube is twisted cap by means of a kind of injection molding at present and is realized that this stubborn cap generally comprises a kind of squeezable wadding.The end of pipe needs a coupling screw thread so that be complementary with cap.Separating molded dress increases manufacturing cost with the cap of liner and the pipe that engraves screw thread.In addition, when this cap was screwed on by screw thread or backed out, cap usually dropped and/or loses.In addition, existing a kind of like this rising tendency promptly has one and can make the hinged cap of the planar end surface of the straight setting of pipe make this pipe of higher cost that still is by providing.Therefore, the cap that uses has such shortcoming at present, and promptly they tend to increase the total manufacturing cost of distribution package.
