Description

  The present invention relates to a can for disposal according to claim 1.

  Various attempts have been made in the prior art to apply film-based packages, for example in connection with the distribution of carbonated or non-carbonated beverages.

  U.S. Pat. No. 5,833,368 discloses a beverage container made of film material. The container comprises a dispensing system that includes a pull tab system that covers the straw inlet area.

  WO 01185560 discloses a further container, which is a stand-up bag made of a heat-sealable plastic film. This container is applied to contain a flowable product.

  The above documents indicate that the dispensing system itself is not suitable as a mouthpiece, i.e. requires an additional dispensing member such as a straw, or the container itself is a tube-like outlet (from which the user can drink directly It has the disadvantage that it is inconvenient to drink directly from a beverage container, compared to conventional dispensing mechanisms such as bottles, cans or glasses. A further problem associated with the dispensing mechanism described above is that resealing is impossible or unreliable.

  It is one of the several objectives of the present invention to provide a disposable can suitable for storing and dispensing carbonated or non-carbonated beverages or liquids, for example.

The present invention is a disposable can formed at least in part by a flexible film material comprising:
The can has a top surface and has at least one pouring mechanism with at least one reseal structure, the pouring mechanism being attached to the can and relating to a disposable treatable can.

  According to the invention, the beverage can is advantageously formed by a film material. The cans are suitable for use in the same way as conventional cans made from solid walls, and at the same time are advantageously manufactured in a very cost-effective manner. Furthermore, the can can be disposed of in a very environmentally friendly manner.

  Furthermore, the can according to the present invention can be easily folded and handled during disposal after use.

  According to the present invention, the can will facilitate the transport and storage of carbonated or non-carbonated beverages and will facilitate drinking by the can dispensing mechanism. Preferably, it will be easy to drink directly without the need for additional accessories such as straws and mouthpieces.

  Furthermore, the present invention addresses the basic use of cans from the user's point of view. This is that the conventional advantages and comfort are obtained with a flexible can with additional advantages such as comfortable and easy folding of the can after use, rather than relying on a compression tool. It can be easily obtained by simply holding the can with your hand.

  In addition, flexible cans can provide a further great advantage, for example with respect to the possibility of incorporating filters or additional internal barriers into the can in a cost-effective manner, which means that many such measures Because it can be obtained by changing the sealing pattern or procedure and / or simply applying a further film which is relatively inexpensive.

  Furthermore, the flexible can according to the present invention can be adapted for specific applications (ie with or without UV barriers, with or without thermal insulation properties, with or without transparency, etc.) Various wall materials are provided.

  According to one feature of the invention, the disposable can formed at least in part by the flexible film material comprises a dispensing mechanism that can be resealed once or several times by the reseal structure. . The reseal structure typically may comprise, for example, a flange or other suitable structure that is attached to the top surface of the can. The top surface of the can can also include, for example, a flexible film material.

  By attaching a reseal structure to the top surface, for example, a lid, plug, plug, cork, etc. can be applied with the structure to reseal the dispensing mechanism as desired.

  Re-enclosed bodies are very attractive for can structures, but note that such re-enclosed bodies are generally expensive and difficult to manufacture in terms of both fixation and material compatibility. I want to be.

  According to a preferred embodiment of the present invention, such resealers and reseal structures are used in conventional waste fuel plants by compatible materials or according to environmentally attractive combustion principles. Shall be biodegradable by combustion, or at least formed by a material that may be degradable.

  The resealer and / or reseal structure will preferably be made of a rigid or at least semi-rigid material to facilitate safe and simple reseal.

  One of several objectives that can be achieved within the scope of the present invention is that the can can be disposed of by the end consumer and the can material produced by applying the polymer is actually incinerated. In other words, toxic combustion products can provide improvements with respect to expected disposal.

  The product of complete combustion of the polymer can usually be carbon dioxide and water, optionally with small amounts of various oxides.

  In any case, the disposal of the type of can applied is further considered more attractive than the existing challenges associated with the disposal of conventional metal cans, for example polystyrene (PS), polyethylene (PE) Polypropylene (PP), polymethyl methacrylate (PMMA) and polyvinyl chloride (PVC) can be incinerated with minimal contamination or undesirable residues.

  When placing a barrier between the inlet and outlet, it is possible to ensure or facilitate that liquid injected into the can from the inlet is directed through the filter to the outlet.

  It is a known problem that water in some parts of the world is contaminated by, for example, health threatening microorganisms, bacteria, minerals, toxins, toxic metals and the like. According to an advantageous embodiment of the invention, the can can also have a water purification material. Thereby, the user of the can can add water at the correct dose given by the volume of the can as compared to the amount of water purification material. This provides a very cost effective and practical way to purify water. In this particular embodiment of purifying water, the flexible can can be reused as opposed to all other applications that can be disposed of. Furthermore, there can be at least one barrier, for example a filter, between the inlet and the outlet.

  Furthermore, the present invention relates to a disposable can, preferably formed by at least one flexible film wall, comprising an inner barrier mechanism. Note that this barrier according to one embodiment of the present invention should basically be placed between the main volume of the can and the outlet, regardless of the design of the top of the can with respect to the dispensing mechanism. . The can basically comprises an inner barrier that allows liquid to flow in the interior volume, in particular from the inside to the outside of the can. The barrier mechanism may simply consist of various flow restricting means in the internal volume, such as a wall with one or more openings, a filter material with small holes, and the like.

  Furthermore, it should be noted that the barrier material can also help to keep the shape of the can stable.

  A much broader aspect of embodiments of the present invention is that cans can be first manufactured and transported in a folded state to a filling station such as a brewery and then expanded during filling. The application of the flexible can according to the present invention greatly improves the physical distribution. Then, when the consumer empties the can, the can can be easily folded to a minimum volume. This is also very true when applying cans with an outer support.

  In one embodiment of the invention, the can comprises a reseal body that includes cutting means, pressing means or piercing means. By these means it may be possible to easily open an additional seal of the can. One embodiment of the reseal body has a slightly inclined downward surface or edge so that when the reseal body is manipulated, for example, torsional movement applied when removing the reseal body By twisting or pushing in the opposite direction, the additional seal can be broken. In other words, the reseal can be applied alone or with a reseal structure as a tool to open an additional seal.

  Finally, the present invention also features a very environmentally friendly provision compared to conventional metal cans.

  The present invention will now be described with reference to the drawings.

  A can generally refers to a normally cylindrical receptacle that holds a liquid or flowable material. Within the field of carbonated or non-carbonated beverages, usually the term carbonated beverages, such a term usually refers to a metal receptacle having a pull tab that can be removed, which has become a world standard for decades.

  In the present context of flexible containers, one of the important can forming features is the so-called top surface. The top surface corresponds to or mimics the conventional top surface of a conventional aluminum can with respect to both the shape of the container and handling and dispensing, which is retained when the can is dispensed, for example. This is because the user can handle the tilt in the same manner as a conventional metal can.

  The top surface may be formed by a single piece or sheet, or may be defined, for example, by an extension of the weld that defines the sheet defining the wall and the corresponding top surface. This will be described in detail in the illustrated embodiment.

  It should be noted that, in general, joints such as heat seals or adhesive seals are permanent and are not intended to peel in principle unless otherwise specified.

  It is further noted that the present invention relates to a can formed at least in part by a flexible film having a dispensing mechanism that facilitates resealing.

  The disposable cans described below are suitable for both beverages or solids such as powders and granules.

  FIG. 1 illustrates one embodiment of a can formed of a flexible film, according to one embodiment of the present invention. The illustrated can is formed by four welded film surfaces: two wall forming surfaces 13, 130, a bottom surface (not shown in FIG. 1), and a top surface 16.

  Different surfaces can be formed by separate sheets by welding, or some of the surfaces can be formed by the same sheet. Thus, the top surface 16 can also be formed, for example, by folding the upper end of one of the side walls 13, 130 instead of applying a separate sheet. The same applies to other surfaces, such as side walls 13, 130, which can optionally be formed by a single sheet.

  One of the important aspects of the can within the scope of embodiments of the present invention is that the can preferably forms the majority of the internal volume of the can container and is preferably at least part of the can visible from the outside. The can structure and can features can be obtained in several different ways, as long as it includes a flexible film that forms a film.

  Thus, according to the illustrated embodiment of the invention, the finished can can be simply manufactured with two or preferably three joined film sheets or notches.

  The illustrated can further comprises a reseal body and reseal structure where a screw cap structure 14 that fits into a screw tab or other suitable closure (not shown) is attached to the outside of the top surface 16. .

  The screw cap structure 14 further forms part of the dispensing mechanism when the film within the outer periphery of the reseal structure is broken or removed to create an outlet from the inside of the can to the outside.

  Reference is now made to FIGS. 2a-2f, which describe the structure in more detail, and the manufacture and application of a slight modification of the can of FIG. 1 is shown. 2B and 2C are cross-sectional views taken along line IIC in FIG. 2A.

  The illustrated disposable can 20 is formed by bonded films 230, 23, 26 and 29, where the films 230 and 23 form the can wall (s), the sheet 26 forms the top surface 26, The sheet 29 forms a bottom surface 29.

  The two films 23 and 230 are joined by side seals 232 and 233. Alternatively, the can 20 may be manufactured based on a single film with one side folded and the other side joined by, for example, a seal 232 or 233.

  The top surface 26 of the can 20 is formed with a reseal structure 24 adapted to fit into a reseal body, such as a screw cap, bayonet cap, or any suitable reseal body. Reseal would preferably be done by a mechanical lock between the reseal structure and the applied reseal. The top surface 26 can also be formed by a separate sheet as shown, or can be formed by the folded portion of one of the side walls 23 or 230.

  The walls 23, 230 and the top surface 26 and bottom surface 29 form a container including the internal volume 231.

  Further, the opening 280 is formed by the reseal structure 24 so that it can be applied as a resealable dispensing opening when the film seal of the opening 280, here a portion of the top surface 26 is broken or removed. Define an outlet. The reseal structure may fit from the start, eg, a removable reseal, or the reseal, eg, a cap, may fit after first breaking the seal formed in the opening 280.

  The top surface 26 has at least one inward fold 27 that allows the can to be inflated from a manufacturing position where it is fully or at least partially folded. In this context, it should be noted that the folding according to this embodiment can be done fairly easily and efficiently if the reseal structure is made as low as possible. This can be seen, for example, in FIG. 2b, where the top surface 26 is effectively folded, which can interfere with the finished can if the reseal structure is too high. . Thus, the plug-like reseal structure 24 that can fit the reseal body into the reseal structure by a single turn of movement, such as a bayonet-like fit, represents an advantageous and very cost effective solution. This will be described later.

  The bottom surface 29 has at least one bottom fold 28 that allows the can to be expanded from a manufacturing position where it is fully or at least partially folded.

  The can has an upper dispensing mechanism 201 formed by a top surface 26, an opening 280, and joints 202 and 204, which define the outer periphery of the reservoir-like structure.

  A reservoir structure with a perimeter defined around the opening 280 removes a portion of the can that seals the opening 280 other than that associated with conventional cans, ie, directly from the top of the can. Allows the user to drink from the can 20 without having to drink.

  The provided dispensing mechanism 201 further allows the user to catch any undesirable spills when drinking as in conventional cans.

  The drinking lip 22, which is optional in other embodiments of the present invention, functions as a support or some type of mouthpiece that assists in attractive handling when drinking. Obviously, such a drinking lip may be avoided, especially if the mouthpiece or spout fits or can be fitted to the reseal structure 24.

  FIG. 2F illustrates the opening through the opening 280 in the reseal structure when the reseal body 205 is removed from the reseal structure of the can, thereby breaking or removing a portion of the top film. Indicates when access to the internal volume of the can is provided.

  2D and 2E show three-dimensional views of the can 20.

  The reseal structure 24 exposes an opening 280 in the reseal structure 24 that becomes an opening leading to the internal volume 231 when broken or removed.

  FIGS. 3A to 3F show a can 30 with a slight modification to the beverage can of FIGS. 2A to 2F where the position of the reseal structure has been changed.

  Here, the reseal structure 34 is attached to the side wall 33, and the re-seal structure 34 can be attached to the reseal structure 34 when the additional seal 380 in the reseal structure 34 of the dispensing mechanism is broken or removed. Can act as a structural part for an enclosure. Thus, in this context, the additional seal functions as the initial seal of the reseal structure, thereby making it easier for the user to first with the can fully sealed without having to reattach the resealer first. To be able to provide. On the other hand, when the resealer is first installed, the additional seal ensures that the risk of resealant leakage is minimized. The can has a main volume 331.

  4A-4C show a further embodiment of the invention based on the can 40 of FIGS. 2A-2F, where a barrier mechanism 410 is provided.

  The barrier mechanism 410 including the sheet 450 perforated by the perforations 420 is fixed to the can and divides the internal volume 431 into two volumes, a main volume 431 and an outlet volume 425.

  Barrier 410 serves several different purposes.

  One purpose is to limit or attenuate rapid flow from the internal volume 431 to the outside through the opening 480 in the reseal structure 44.

  Another object may be to act as a filter for residues that should not flow out when emptying the can. Such residues can include, for example, dietary fiber, small fruit pieces, and the like. Obviously, the above-described embodiment is basically liquid unless the barrier mechanism is carefully designed to allow the contents of the main volume 431 to pass from the inside through the opening in the barrier and reseal structure. Most suitable.

  Another important purpose of the barrier may be to add shape stability to the flexible can.

  Obviously, several other barrier mechanisms can be made within the scope and spirit of the present invention.

  Figures 5a to 5f show the function of the reseal mechanism applied within the scope of the present invention.

  FIGS. 5 a, 5 c, 5 e and 5 f show a cross section of a reseal mechanism comprising a reseal structure 54 and a corresponding reseal body in the form of a plug-like lid 505.

  FIG. 5 a shows a cross section of a lid 505 that is fixedly disposed on the reseal structure 54. In this case, the lid is mechanically locked to the reseal structure 54 mainly by a flange 507 extending inward of the reseal body and a flange 541 extending outward of the reseal structure 54. Yes.

  Further, FIG. 5a shows that the resealer 505 is initially from the top of the underlying flexible film 56, preferably one of the cans illustrated herein, for example by thermal welding, adhesion, nanotechnology, etc. Indicates that it is attached to a part. In this case, such an upper surface may be, for example, the upper surface 26 of the can 20 or the upper surface 46 of the can 40.

  Further, according to another embodiment of the present invention, the underlying flexible film as described above may be part of another wall of a film-based can as shown in can 30 of FIGS. 3a-3c. May include, thereby forming an additional seal 5801. Additional seals of the type shown are typically not fully resealable, but of course form part of and participate in a complete reseal mechanism.

  The reseal structure can be cast or molded from a suitable material by any suitable molding technique and any suitable material. However, it should be noted that both the reseal body 505 and the reseal structure 54 would preferably be made of a material that is compatible with the can or at least a majority of the can. Such considerations can relate to environmental issues such as disposal and incineration, and even to inter-mounting. Thus, when applying a compatible material at least in the boundary area between the underlying surface and the contact portion of the reseal structure 54, the two parts are heat welded or bonded together. .

  According to an advantageous embodiment of the invention, the upper surface is at least partially covered by an additional seal in order to hygienically protect the part of the can applied during drinking until the can is first opened And Additional seals may include, for example, a sheet covering the opening and, for example, a portion of the can rim.

  According to the illustrated preferred embodiment of the present invention, the additional seal should form a seal that itself provides a suitable and sufficient can seal. Preferably, therefore, perforations that facilitate removal of the additional seal 5801 should be avoided to ensure that the can is completely sealed until the user is reached. In addition, this may have the advantage of helping to maintain the quality of the can contents.

  However, according to a further preferred embodiment of the invention, the additional seal may be accompanied by a weakening line or other suitable “breaking aid” means.

  In FIGS. 5c and 5d, the lid 505 is rotated approximately 10-40 degrees and the additional seal 5801 is broken because it is fully attached to the bottom surface of the lid 505, for example, by thermal welding or gluing. . Here, the lid 505 is rotating and a portion of the lid is no longer mechanically engaged with the flange 541.

  In FIGS. 5e-5g, the lid 505 is rotated about 90 degrees, where it is not engaged with the reseal structure and can be removed. An additional seal 5801 is attached to the bottom surface of the lid and is removed with the lid 505 to create an dispensing mechanism formed at least in part by an opening 580 formed in the ring-shaped reseal structure 54. Please note that. This opening can be resealed by rotation of the lid 505.

  The lid can be locked in several different ways. Thus, a click lock may be applied between the flange 541 and the corresponding flange of the lid to create a squeeze lock or pinch lock, or a slight tilt may be created.

  Such a lock can also be supplemented by a click mechanism.

  Additional outlet mechanisms suitable for dispensing are shown, for example, in US Pat. No. 3,930,286, which is hereby incorporated by reference.

  6a and 6b show perspective views of the reseal body 54 and corresponding reseal structure 505 of FIGS. 5a-5f, and FIG. 6b shows the lid of FIGS. 5e-5g open from its sealed position. And shows the situation where the reseal structure defines an opening 580 that may be used for entry or dispensing.

  Figures 6c and 6d show a perspective view of the reseal, corresponding to the embodiment shown above, but with the lid changed here. Reseal structure 64 may be the same as shown, but obviously it may be modified if desired.

  In this embodiment, the lid cover extends to form a complete lid, while the inwardly extending flange 507 is maintained to provide the same mechanical lock as described above. To make it easier.

  6e to 6g show that the cap closure 805 is attached to or can be attached to the reseal structure 84 by fitting the screw cap to the thread 841 of the reseal structure 84. 8 shows a further embodiment of the present invention that can be released from 84. Again, the reseal structure is simply glued or welded to a portion of the can, preferably the top surface.

  If a specific height of the reseal structure is possible, the application of a screw lock is most attractive.

  FIG. 6h shows a further embodiment of the present invention corresponding to the embodiment shown in FIGS. 6e-6g with a reseal structure 94 that facilitates screw locking of the cap 905. FIG. In this embodiment, blades 942 and 943 are attached to the reseal structure, and the risk that the reseal structure 94 is unintentionally detached from the can (for example, the upper surface of the can) by these blades 942 and 943. The user can tighten the screw cap without any problem.

  FIG. 7A shows a can that can be disposed of according to one embodiment of the present invention. The can 60 may fully correspond to the can 20 of FIGS. 2A-2F, for example.

  The can 60 fits within a rigid tube structure 601 that forms the outer support of the can 60 and can be provided with a bottom support 603 and a top lid 602.

  8A and 8B show a further embodiment of a flexible can 70 supported by an outer support 701 according to the present invention. The can 70 generally corresponds to the can 20 shown in FIG. 2A, but here does not have an extended drinking lip.

  The can 70 is disposed in a cylindrical outer support 701, the bottom is supported by the bottom support 703, and the top is protected by the upper support 702. Further, the bottom support is formed with a shape 753 suitable for mechanically securing the outer support 701.

  All support components 701, 702, 703 may be fixed to each other or fully or partially openable.

  Furthermore, the can can be fixed to the outer support, for example by gluing or welding, or simply mechanically fixed by the outer support mechanisms 701, 703.

  When applying flexible cans for carbonated beverages, all surfaces of the can can have outer supports, ie, an outer support 701, a bottom support 703, and an upper support to offset significant pressure in the can. Suppose that it is supported by the support body 702.

  9A and 9B show a further embodiment of the present invention in which the can 80 is disposed within the outer paperboard support 801. The can 80 generally corresponds to the can 10 shown in FIG. 1 (ie, corresponding to FIGS. 2a-2f), but here has no extended drinking lip.

  The outer support 801 has a release strip 808 that is integral with the outer support and has a handle 807.

  FIG. 9B shows the case where the release strip has been removed and the outer support has been split into two separate portions 801, 802, at which point access to the can 80 is facilitated.

  In the illustrated embodiment, further embodiments will now be described. This embodiment includes carrying the can 80 into the outer support 801, 802 to the consumer.

  The user breaks the seal 808 as described above and removes the can 80 from the outer support 801. The user then opens the dispensing mechanism to pour the liquid contained in the can 80 into the lower outer support 801 and finally drink the liquid from here using the lower outer support 801 as a cup.

  10A-10H illustrate several alternative embodiments of the use of an outer support mechanism for use with a can (eg, can 10).

  The outer support mechanisms include outer supports 901A, 901B, 901C, 901D, 901E, 901F, 901G, 901H, upper supports 902A, 902B, 902C, 902D, 902E, 902F, 902G, 902H, and bottom supports 903A, 903B. , 903C, 903D, 903E, 903F, 903G, and 903H.

  When applying a carbonated liquid can and an outer support mechanism, the outer support has a very important function of resisting the pressure in the can, ie the film structure is relatively high to which the carbonated liquid is attracted. Do not break by pressure. Thus, using a combination of a flexible can and an outer support solves the problems associated with maintaining carbonated liquid in a flexible container that has not been solved before.

  The outer support may be advantageously formed of a paperboard-based structure that is relatively rigid and made of a shape-stable polymer.

  The can can fit loosely within the outer support or be secured to the outer support.

The outer support can serve several different purposes:
Keeping the can in the desired shape,
Facilitating packing, transporting to shelves and stacking;
Adding strength to flexible cans and facilitating filling of carbonated soft drinks.

  In one embodiment of the invention, the liquid impervious material of the can has a thickness in the range of 10 μm to 2 mm, preferably 40 μm to 500 μm, more preferably 60 μm to 200 μm, and most preferably 80 μm to 150 μm.

  In one embodiment of the invention, the multilayer structure of the can includes an outer film, an optional intermediate barrier layer, and an inner layer of polymer sealant.

  The material of the filter mechanism and / or the liquid permeable inner compartment material may include a pierced material, an etched material, a molten material, a stamped material, or a cutting material. The material may include, for example, plastics, polyolefins such as polyethylene or polypropylene, polyesters, polyamides, and other polymers, woven or non-woven foamed plastics, cloths, screens, wire meshes, metals or injection molded plastics.

The filter mechanism forming sheet may be composed of a liquid permeable sheet material having a hole density in the range of 1-30 holes / cm ² , preferably 2-20 holes / cm ² , most preferably 4-12 holes / cm ² .

  The holes are 0.01 mm × 0.01 mm to 2.00 mm × 2.00 mm, preferably 0.1 mm × 0.1 mm to 1.0 mm × 1.0 mm, more preferably 0.1 mm × 0.1 mm to 0.00 mm. It may have dimensions in the range of 6 mm x 0.6 mm.

  The flexible can wall film (s) may be comprised of, for example, a multi-layer laminate material comprising three layers. That is, an outer layer made of PETP, for example, an intermediate layer as a barrier layer made of aluminum foil such as 9 μm foil, and an inner layer forming a sealant containing 80 μm to 120 μm polyethylene (PE). Multilayer laminate materials typically can include two or more layers.
