Description

The invention relates to a method for producing a package, in particular a film package with a bubble-shaped receiving space, in particular for producing a blister package, according to the preamble of claim 1.

The invention also relates to packaging according to the preamble of claim 2.

The invention also relates to a device for producing at least one package according to the preamble of claim 3.

Methods and devices for producing packaging and packaged objects by means of films are generally known. In particular, methods and devices for producing blister packs are known. Plastic foils are used that consist of polyolefins such as high and low density polyethylene (PE) or polypropylene (PP). In addition, films made of polyvinyl chloride (PVC), polystyrene (PS), various polyesters and polycarbonate (PC) are also known. Other bio-based plastics such as polylactide (PLA), cellulose acetate and starch blends can also be processed into films and are used accordingly. Multi-layer composites are also often made from a combination of different plastics. This enables certain properties, such as permeation behavior, to be improved. Such plastic films are often used as packaging. A typical use of plastic films is in blisters or blister packs. A transparent packaging is a product packaging that allows the customer or buyer to see the packaged item to see. The object, the shaped object or the product is presented in front of a rear wall, which is usually printed with information, and fixed with a plastic film molded part. For some transparent packaging, the back wall is made of plastic, for medication it is made of aluminum. A distinction is made between welding packaging, clip packaging and booklet packaging. In the case of welded packaging, the front of the film and the back of the film are connected to one another by heat, which is also a trademark. In the case of clamping packaging, the edges of the film front part are bent around the rear wall by heating the plastic. In the case of staple packaging, the film front and the back of the cardboard are connected to one another by means of staples. The blister contour is shaped using thermoforming technology.

Thermoforming is a process for forming thermoplastics. It used to be called thermoforming, deep drawing or vacuum deep drawing. A distinction is made between the thermoforming processes according to the semi-finished product used: thinner semi-finished products are called foils, thicker (from approx. 1.5 mm) sheets. Semi-finished film can be fed to the thermoforming machines on large (up to Ø 1.8 m) rolls. In addition, thermoforming is the tool for thermoforming. Articles made of thin foils (0.2 to 1 mm) such as chocolate box inserts, foam kisses packaging, cardboard inserts, folding blister packs for all kinds of small items on perforated grid walls in retail, yoghurt or margarine cups are widely used. This also includes sliding card blisters, sealing hoods and the hard-to-open folding blisters, in which small parts are often sold and which are welded using high-frequency HF electrodes. The film is guided by large rolls on the film web edges in so-called spiked chains. The still hard cold film is first fed to the molding machine and then passed through in cycles. In a warm-up station, radiant heaters are controlled via industrial heating controls and the film is heated on one or both sides. The warm, now softer film is slightly pulled apart in the spike guides so that it does not sag as much. The film is held in the tool station by means of a tenter, the pre-stretcher and the thermoforming tool pass through the film plane and roughly specify the finished contour. Then compressed air comes from one side and vacuum from the other to bring the film quickly and strongly to the water-cooled wall (contour) of the aluminum mold. The air escapes between the film and the aluminum tool through 0.5 to 0.8 mm small holes and / or 0.2 to 0.3 mm wide slots. The cooled, now firm film is separated from the molding tool and fed to the punching station in the next working cycle. There, the outer dimensions or holes are punched into the finished workpiece using a steel strip. In the next cycle, the article is removed manually from the thermoforming machine or using a stacking shaft, clipboard, lifter and squeegee stacked automatically. The finished film articles are then manually removed in batches, often packed in poly bags and placed in boxes. There are also other types of thermoforming, which are only briefly listed here: high-performance machines work with hardened steel tools and punch out the foil articles at the same time as they are being shaped. Medium series machines are e.g. T. operated only with vacuum or compressed air. Small batches are occasionally produced from a small roll or from film plates in semi-automatic machines and the parts are then separated using a roll punch and a steel strip. Even complex designs can be realized with sliders, folding and rotating cores. You can also punch on more than one level. In the past, packaging was cuboid; today they are almost always adapted to the often complex geometries of the items to be packaged or only because of this they are provided with curved surfaces and edges in order to obtain individual "modern" packaging.

Blistering is often disadvantageous because of the high packaging waste, especially with small objects, and the poorer ecological balance of plastic compared to cardboard. In addition, the removal from the blisters is quite cumbersome. The known blister packs also become unusable after the first opening, making it difficult to return the packaging. Furthermore, opening blister packs made entirely of plastic can be extremely difficult at times, since the front and back are usually welded together and it is very difficult to open them cleanly and easily without any tools. In addition, injuries can occur on the cut edges when opening the blister. After opening, the packaging waste often takes up a larger volume than in the packaged state. This has an adverse effect on disposal.

The invention has for its object to provide a packaging and methods and devices for their manufacture, which are compared to the prior art (see WO 2013/156747 A2 ) have improved properties and which are in particular easier to open and environmentally friendly. In addition, the packaging is suitable for a variety of objects such as candies, liquids, powders or other. In particular, reusable packaging is to be created.

This object is achieved by the features contained in the independent or subordinate claims. Advantageous developments of the invention are specified in the dependent claims.

The invention includes the technical teaching that in a method for producing a packaging, in particular a film packaging with a bubble-shaped Receiving space, in particular for producing a blister pack, comprising the steps: overlapping of at least two film elements, shapes of at least one receiving space for accommodating at least one molded article to be packaged - or shorter object - between the overlapping film elements and connecting the at least two film elements along at least partially at least around common sealing edge area encircling the receiving space, in particular by means of at least one seal weld - also referred to as a sealing seam - in order to seal the receiving space, the two film elements being formed so as to protrude from the sealing edge area so that the opening means and / or retaining means for retaining the packaged object can be provided at least when the packaging is open, which allow simplified access to the receiving space without the counterpart being unwanted from the receptacle hm room came out. The retention means are in particular integrated or provided in the packaging, preferably in the receiving space. The retaining means here include formations, recesses, undercuts and the like, which are preferably directly adjacent to the receiving space. In one embodiment, the projections protrude into the receiving space from the film elements. In other embodiments, the recesses on the film elements protrude away from the receiving space. When the object is filled, in particular in liquid form, that is to say in a state in which the object is melted, the retaining means are surrounded by the liquid object. When hardening, the hardened object then continues to surround the retaining means, so that when the packaging is opened, the object still adheres to the retaining means at least for a short time. The retention means are designed such that they enable separation from the object, for example by means of suitable surfaces, for example with bevels, roundings and the like. In other embodiments, the retaining means are designed in such a way that the object to be molded in the receiving space has a predetermined breaking point, which then causes the object to break when the object is removed, so that a large part of the object can be easily removed. A minimal remnant of the item initially remains in the packaging. In one embodiment, the article remaining in the packaging can be removed after the majority of the article has been removed. In other embodiments, the remaining part is so small that it remains in the packaging.

Two film elements are conveyed in the process. In one embodiment, the film elements are connected to one another and form a film web. In this case, the film is bent by 180 ° in a longitudinal axis oriented in the direction of travel, so that the two halves of the film are arranged on one side lying opposite each other from the longitudinal axis.

In another embodiment, the film elements are not connected to one another. Each film element thus forms its own film web, which is fed in each case. To overlap the film elements, the film webs are preferably formed parallel to one another. Possibly. the film webs are synchronized via a synchronizing device, so that corresponding parts of the film webs are aligned and / or positioned with respect to one another. Depending on the end product, the foil elements, foil webs or foils for short are arranged congruently or only partially overlapping. The film elements are shaped to form a receiving space between the film elements. Molding is preferably carried out using a thermoforming process. The film is shaped under the action of heat, which softens the film for deforming. This is preferably done using a molding tool or a plurality of molding tools, preferably in one work step, in other embodiments also in several work steps. In one embodiment, the foils are deformed symmetrically to one another, that is to say the two foil elements have the same receiving space contour. In another embodiment, the receiving space contours are designed differently for each film element. In order to form the receiving space by means of a molding tool, an overpressure is generated between the foils in the molding tool, which presses the softened foil elements against the contour of the molding tool. In another embodiment, a negative pressure is generated between the film elements and the molding tool, which moves or deforms the film elements in the direction of the wall of the molding tools, as a result of which the respective receiving space is generated. In a preferred embodiment, the receiving space is closed by means of a (seal) weld - or also called a sealed seam. The welding is therefore preferably carried out with a sealed seam. In other embodiments, several sealing seams are provided. With the welding, a film edge, which surrounds the receiving space in the plane of the film elements, is welded to the opposite film edge of the corresponding film element. In one embodiment, the sealing seam is formed uniformly along the film edge. In other embodiments, the sealing seam along the film edge or the edge of the receiving space is designed differently. The sealing seam is preferably interrupted at one point in order to form a filling opening. In a further step, the object or also a filling material is introduced into the receiving space through this filling opening. The object is preferably filled into the receiving space in a liquid or flowable form. The object is preferably filled into the receiving space in liquid or gaseous form. After filling or pouring the filling opening is sealed. In another embodiment, several filling openings are provided. Accordingly, the sealing seam or the welding is interrupted several times over the entire circumference. The interruption can be provided at any point. In one embodiment, the interruption of the sealing seam or the filling opening is arranged on a line of gravity of the packaging. The gravity line is an imaginary line that arises when the packaging is suspended at one end by gravity from the suspension point along the gravity field. The gravity line also results from a volume center of gravity of the packaging along the gravity field. In a preferred embodiment, the filling opening is spaced or offset from and / or rotated relative to the gravity line. In one embodiment, the welding or the sealing seam has reinforcements and / or weakenings. In one embodiment, the sealing seam is reinforced by means of one or more embossments. In another embodiment, a plurality of sealing seam reinforcements are provided. In the area of the sealed seam reinforcement, the film elements remain connected to one another longer when they are opened than in other, non-reinforced sealed seam areas. Here, a kind of joint for the film elements is realized through the reinforcement of the sealed seam. Accordingly, the film elements are easier to separate from one another in the event of a weakened sealing seam. The separation of the film elements for access to the receiving space relates to a separation of the film elements along a contact plane of the film elements in which the film elements make contact. It is further provided that the film elements are designed to be free of interstices adjacent to the receiving space and projecting therefrom. The receiving space is preferably surrounded by a space-free area of the film elements, which forms the edge area or the film edge around the receiving space. The edge area or the film edge is preferably designed differently in the circumferential direction around the receiving space. In a preferred embodiment, the edge area on one side of the receiving space is wing-like, whereas the remaining edge area is evenly spaced around the receiving space. The transition from the wing-like edge region to the uniform edge region is continuous in one embodiment and abrupt in another embodiment. The filling opening is or the filling openings are arranged in the uniform edge area. The uniform edge area preferably measures a few millimeters in the film plane. In particular, the width of the edge region in the film plane is less than 5 mm, more preferably less than 3 mm, more preferably less than 2 mm. In one embodiment, in the area of the filling opening, the edge area in the film plane, that is to say in the contact area of the film elements, is wider than the remaining uniform edge area. The edge area in the area of the filling opening is designed to be significantly smaller in terms of area and / or volume than the other uniform edge area. Prefers is a ratio of the areas or the volumes of the edge area filling opening to the remaining uniform edge area less than 0.5: 1, preferably less than 0.4: 1, even more preferably less than 0.3: 1, further less than 0.2: 1 , and most preferably less than 0.1: 1 and less. The wing-shaped edge area adjoining the uniform edge area is designed to protrude from the receiving space in the manner of a tear-open tab. In one embodiment, the overlapping film elements are of identical design in the area of the wing-shaped area. That is, the wing-shaped edge regions are congruent or essentially congruent. In another embodiment, the film elements in the area of the wing-shaped edge area are uneven. As a result, only a part of the one film element is covered by the opposite film area. In order to open the receiving space, opening means are provided which make opening easier. The opening means are designed in such a way that they allow one-handed opening. Another embodiment provides that the opening means enable easy opening with both hands. In a further embodiment it is provided that the opening means enable both one-handed and two-handed opening. In one embodiment, the opening means are formed in the wing-shaped edge region, in particular are designed to be integrated. In another embodiment, the opening means are formed in the area of the film elements delimiting the receiving area. In yet another embodiment, the opening means are formed in the edge area surrounding the receiving area. Yet another embodiment provides for a combination of the opening means in the edge area, in the wing area and / or in the receiving area. The opening means are designed in such a way that, in one embodiment, they simplify a separation of the film elements which are connected to one another, that is to say a separation of the sealing seam, at least at the locations provided for this. In another embodiment, the opening means are designed to separate a film element itself, for example in the area in which it forms the receiving space. A further embodiment provides that the opening means both for separating the film elements from one another and for separating an individual film element, that is to say for separating a film element in at least one area. Furthermore, one embodiment provides that the opening means are designed to separate the sealing seam. The opening means are preferably integrated in the packaging. The opening means are designed as mechanical opening means. In another embodiment, the opening means are designed electrically, electronically, magnetically, chemically and / or mechanically. The tear-open tabs are in the area in which the film elements are overlapped and sealed to one another. In one embodiment, the entire overlapping area is sealed. In a further preferred embodiment, only a part of the overlapping area is sealed.

A preferred embodiment provides that the area from the sealed, overlapping area to the unsealed, overlapping area is less than 1: 1, preferably less than 0.75: 1 and more preferably less than 0.5: 1. Preferably, the smallest possible overlapping area is sealed. On the one hand, the sealing takes place directly adjacent to the receiving space in order to seal the receiving space appropriately tightly. On the other hand, sealing takes place at the edges of the overlapping film elements. An edge area is not sealed so that it is easier to grasp for opening. In one embodiment, a distal end of the wing-like area is split to facilitate gripping. That is, the film elements are separated from one another at the distal end. In one embodiment, the distance between the separated film elements is constant. In a preferred embodiment, the distance between the separated film elements is variable. The film element preferably has a curvature at the end, so that the respective film element is easy to grasp. The curvature of the film elements is preferably designed in the opposite direction. In an airworthy embodiment of the packaging, the edge area is designed like a wing in an aircraft. At the outermost edge of the wing-like area, the film elements such as wing flaps then protrude from the film plane, as a result of which the flight properties and / or the rotational or sliding properties are improved. Appropriate flow guide means can be provided at the ends, for example nozzles, openings, projections, recesses, for example ribs, knobs and the like. As a result, a corresponding flow profile is realized at the corresponding ends of the wing-like regions.

In one embodiment of the invention it is provided that a peel-off unit, a pop-off unit and / or a squeeze-off unit are provided as the opening means. For the purposes of the present invention, a peel-off unit is a unit in which the films are at least partially pulled off one another for opening, in particular under the action of a tensile force. The film elements are separated along their contact area. During the separation, a corresponding sealing seam is then opened, which connects the film elements to one another. The separation takes place at the designated places. If the sealing seam is weakened, it is easier to separate or peel off than in places with a reinforced sealing seam. Force must be applied correspondingly unevenly if the sealing seam is to take place in different sealing seam regions. In one embodiment, the sealing seam is reinforced in such a way that separation or peel-off is not possible or is only possible with excessive force. In one embodiment, a peel-off unit can be closed again, for example in the case of adhesive, Velcro, and / or form-fitting connections by means of embossments, clips, push buttons, formations and corresponding recesses and the like. Under a pop-off unit In the sense of the present invention, a unit is understood in which a film element itself is separated by the action of force. The separation or pop-off is preferably carried out by applying force by means of pressure. In this case, pressure is applied to the corresponding film element from the outside, which at least partially separates the film element, for example causing it to burst open. Accordingly, the receiving space is preferably pressurized, so that it can burst open more easily if there is additional external pressure. In the case of a pop-off solution, in a preferred embodiment the packaging cannot be resealed or can only be closed with additional means. Another embodiment provides a resealable pop-off unit or solution. The pop-off unit is preferably provided for opening the packaging with one hand. The peel-off unit is preferably provided for two-handed opening of the packaging. For the purposes of the present invention, a squeeze-off unit is understood to mean a unit in which the packaging is opened by the action of force on the internal object, which then presses the force from the inside against the sealing seam and separates it at the locations provided for this purpose. Here the sealing seam is separated by applying force to the object from the outside through the film elements and a force transmission from the inside against the sealing seam. The packaging is opened and / or the object is removed in a movement dependent on the sealing seam and the design of the receiving space. In one embodiment, a translatory movement is provided. In another embodiment, a rotational movement is provided. In other embodiments, a combination of translatory and rotary movement is provided.

In a further embodiment it is provided that at least one tear-open tab is provided as the peel-off unit, which is formed by means of the two film elements protruding from the receiving space. In one embodiment, the tear tab is formed symmetrically with congruent film elements. The plane of symmetry here represents the contact area between the film elements. Thus, the two film elements in the area of the tear tab are formed mirror-symmetrically to the contact plane of the film elements. In another embodiment, the two parts that form the tear tab are asymmetrical. Accordingly, the film elements in the area of the tear tab are not congruent. A film element differs from the other film element in terms of shape, material and or thickness in the area of the tear tab. The opening is then similar to peeling a banana. In other embodiments, the tear-open tabs are not essentially flat, that is to say in one plane, but instead form a three-dimensional contour, for example in the form of a cylinder. Accordingly, several tear-off tabs can be formed on the three-dimensional contour, so that a peel-off is even more similar to peeling a banana he follows. In one embodiment, the receiving space projects into the wing-like area. In this case, the wing-like area has a three-dimensional structure. To form the tear-open tab, the parts protruding from the receiving space - tab parts - are welded by means of a sealed seam, an area for gripping and / or forming a three-dimensional contour or structure being formed without a sealed seam. To tear open the tear-open tab, the tab parts are pulled apart, the tear-open tabs separating in a tear-open direction toward the receiving space. By separating the film elements, the recording space is also exposed. The bracket parts are designed for easy force application. It is provided in one embodiment that the extension of the tear-open tabs in its greatest extension direction and / or in the tear-open direction is made larger than the largest extension of the receiving space in its largest extension direction and / or in the tear-open direction. In other embodiments, a shorter tear tab is provided. The ratio of the extension of the tear-open tab to the extension of the receiving space, in its respective greatest direction of extension and / or tear-open direction, preferably in the contact plane, is selected from a ratio of approximately 5: 1, preferably approximately 4: 1, further preferably somewhat of 3 : 1 and most preferably about 2: 1. In other embodiments, a 1: 1 ratio is provided. The conditions are preferably intended for packaging with a peel-off unit. In another embodiment, preferably for packaging with a pop-off unit and / or with a squeeze-off unit, other conditions are provided. In particular, shorter tear-open tabs are provided here, so that ratios of approximately 1: 1, 0.9: 1, 0.8: 1 up to 01: 1 result.

In order to enable easy tearing, a tearing direction is curved, preferably curved, in the plane of the film. In one embodiment, the tab parts are provided with a sealing seam only at their edge. The sealed seam is preferably carried out uniformly, that is to say with a constant cross section or a uniform width. In other embodiments, the sealing seam is made with a different cross section or with an uneven width. The sealing seam is designed for easy opening.

In another embodiment it is provided that at least one predetermined breaking point, an at least partial sealing seam reinforcement of the seal weld and / or at least one force introduction element is provided as a pop-off unit and / or as a squeeze-off unit. In one embodiment, a predetermined breaking point is formed in and / or on at least one film element itself. A predetermined breaking point is preferably provided in each film element to form a suitable predetermined breaking point. The predetermined breaking point is formed for example by a material thinning and / or by a groove, a depression, a gate or the like. In another embodiment, the predetermined breaking point is provided in the sealed seam. Yet another embodiment provides that a predetermined breaking point is provided both in the sealed seam and in the film element. Furthermore, one embodiment provides that at least one sealing seam reinforcement is provided. In one embodiment, the sealing seam reinforcement is formed by an additional embossing. In other embodiments, the sealing seam is formed by a larger cross section compared to another area of the sealing seam. In further embodiments, a combination of embossing and a larger cross section is provided. In one embodiment, a plurality of sealing seam reinforcements and / or sealing seam weakenings are provided. In a further embodiment, sealing seam reinforcements are provided for a targeted opening of the receiving space. In still further embodiments, the sealing seam reinforcement is designed such that it holds the film elements together during a peel-off, pop-off and / or squeeze-off. The sealing seam is inseparable on the corresponding reinforcement by means of the aforementioned operations, so that this reinforcement acts as a joint or hinge. The two film elements accordingly remain permanently connected to one another.

In a preferred embodiment, closure elements are provided on the packaging, which enable the packaging to be closed again. The closure elements are designed, for example, as a Velcro fastener, as a snap fastener, as a clip fastener or the like. In this way, packaging can be used several times.

The sealing seam is designed such that it seals or closes the receiving space around the circumference. In one embodiment, the sealing seam is interrupted. The interruption is preferably provided at a filling opening. In a preferred embodiment, a filling opening that is fluidly connected to the receiving space is provided on the packaging. The filling opening is designed to fill a flowable object into the receiving space. Correspondingly, the filling opening extends into a filling opening from the receiving space to over or to the outermost edge of the corresponding part of the film element, so that filling is facilitated.

The filling opening is arranged at a point offset from a gravity line of the packaging. The gravity line results from the suspension of the packaging at a point through this point along the gravity lines of the surrounding gravity field. In another embodiment, the center of gravity of the packaging results from a mass and / or center of gravity of the packaging along the gravity lines of the gravity field. The filling opening is preferably arranged laterally offset from the gravity line. The filling opening is preferably arranged rotated with respect to the course of the gravity lines. In one embodiment, the filling opening is formed in the extension of a tear direction of the tear tab. In another embodiment, the filling opening extends offset to the tear direction. The filler opening is preferably not rotated relative to that of the tear-open direction. The filling opening is formed integrally through a space between the film elements, preferably an approximately cylindrical space. Other spaces are provided in adaptation to a filling device.

Yet another embodiment provides that the packaging, in particular the filling opening and / or the receiving space, have at least one undercut and / or another shaping and / or recess, or an undercut or a shaping and / or a recess is provided there , The undercut causes the object to be held back when the receiving space is opened. In this way, the object does not fall out of the packaging unintentionally, but remains in the opened state at least temporarily. The undercut or the molding / recess is preferably formed integrally with the film element in the region of the filling opening and / or the receiving space.

The invention further includes the technical teaching that in a method for producing a packaged molded article, in particular a packaged article suitable for consumption, such as a food and / or a food and / or nutritional supplement, in which at least one pack is produced according to a the method described above is provided, after the shaping of the receiving space, the object is filled into the receiving space through a fill opening in a liquid and / or flowable form and the fill opening is closed by means of a seal weld.

In one embodiment, a packaging described above is provided. A filling device is guided through the filling opening, for example a filling nozzle or another filler neck. The object is brought into the receiving space by the filling device. The object is fluid and / or fluid. This can be both gaseous, liquid and / or a combination thereof. The object is preferably designed as a hardening object. In a preferred embodiment, at least two different objects are in the receiving space filled. The objects are preferably at least temporarily filled into the receiving space at the same time. In a preferred embodiment, a first object is first filled into the receiving space. To do this, a second object is filled in at different times, so that the two different objects are filled into the recording space at the same time. In a further embodiment, the filling of the second object is stopped before the filling of the first object is stopped, so that the second object is at least partially, preferably completely, surrounded by the first object in the receiving space.

In one embodiment, the object is colored. The film element is at least partially transparent in the first part, that is, in the part in which the receiving space is formed, so that the object can be recognized from the outside. The object is preferably colored. In one embodiment, a device is provided as the filling device, which has two filling channels through which the object flows. In one embodiment, the filling channels are formed side by side. In another embodiment, the channels are formed one inside the other so that an outer channel surrounds an inner channel. In one embodiment, the filling takes place after completion of the packaging in a separate filling device. In another embodiment, the filling takes place integrated in a device for producing the packaging. After thermoforming, the object is filled into the receiving space and then closed on the manufacturing device, so that the fully packaged item leaves the manufacturing device. In one embodiment, the receiving space has a plurality of chambers. In one embodiment, the chambers are filled differently. In one embodiment, a liquid or flowable object is filled in one chamber and a gaseous object in another chamber. The two chambers are then closed accordingly. In one embodiment, the sealing takes place with the film element itself. In another embodiment, a separate closure is provided for at least one chamber. The separate closure is preferably coupled to the film element, so that when the receiving space is opened, at least one chamber, preferably all the chambers, are also opened.

The object is preferably an object intended for consumption by humans and / or animals. The object is at least partially in a solid state at room temperature (about 20 ° C.) and at normal ambient pressures (around 1 bar). In other embodiments, the object is at least partially in liquid form under the aforementioned conditions. In one embodiment, the object is in a state, that is to say solid, liquid or gaseous. In another embodiment the object exists in several states, for example liquid and solid or liquid and gaseous. The object has several areas, preferably an inner area which is encapsulated by an outer area. The inner area is preferably provided for a liquid and / or gaseous state. The outer region is preferably provided as a solid state, also as a jelly-like state, for example for a soft capsule. The object is designed, for example, as an object hardening with cooling. The object can thus be filled into the receiving space through a needle or nozzle in the heated liquid and / or gaseous state. The object hardens accordingly when it cools down.

In one embodiment it is provided that the receiving space, with the exception of the filling opening, is sealed with the seal weld before the preferably flowable object is filled. Except for the filling opening, the receiving space is sealed in an execution opening. In one embodiment, the sealing takes place with a uniform sealing seam. In another embodiment, the sealing is carried out with a varying sealing seam. After the object or objects or the filling material has been filled in, the filling opening is closed. In one embodiment, the filling opening protrudes from the film element as an attachment to the film element. The edge area around the receiving space, that is to say the first part of the film elements which are formed without gaps, is preferably less than 3 mm wide, more preferably less than 2 mm and most preferably less than 1.5 mm, in each case as the shortest distance from the outermost edge to the adjacent to the receiving space in the film plane or in the contact plane edge. The area of the filling opening, that is to say the attachment in which the filling opening is provided and which is formed without gaps after filling, is preferably less than or equal to 3 mm, more preferably less than or equal to 2 mm, and most preferred in the shortest extent to the receiving space in the film plane less than or equal to 1.5 mm. The filling opening is preferably closed with a reinforced sealing seam, so that the area of the filling opening functions as a joint when the packaging is opened.

In one embodiment it is provided that the method for manufacturing soft capsules is designed. So far, soft capsules have been produced using a rotary die principle. With the present method, soft capsule production can be carried out using Mughal technology. The mass for the soft capsules, for example glucose syrup, gelatin or the like, is filled directly into the packaging. The mass or the ingredients for the object to be packaged is / are poured into the receiving space in liquid form, here in a hot state. In one embodiment, the receiving space faces the wall thereof a starch powder or other coating. In a preferred embodiment, the wall has no starch powder or any other coating and is therefore designed to be coating-free. With hardening, for example by cooling, the cast object can be removed directly from the packaging without the need for complex handling steps. An improved Mogul technology method is thus provided. Objects can be produced which have a profile on both their top and bottom, depending on the shape of the film elements around the receiving space. The object does not have a smooth or flat surface as before, due to the liquid state in which the object is poured into the open mold. Rather, the liquid object is poured into a closed receiving space, except for the filling opening, in which the liquid object then hardens or cools. In a further embodiment, another object is cast in the packaging around the liquid first object. In one embodiment, the two objects have different consistencies at room temperature and / or ambient pressure. In one embodiment, the outer article is in a firmer state than the inner article at room temperature. Thus, in one embodiment, a liquid inner object with a firmer outer object surrounding it can be produced in the packaging and removed from it. For example, the outer object is designed, for example, in the form of a hard and / or soft capsule. The inner object is, for example, a liquid mass, all at room temperature in a range around this room temperature. The room temperature is preferably in the range of 18-22 ° C. The area around the room temperature is, for example, plus / minus 5 ° C., preferably 10 ° C. A pressure for the above information is preferably in the range of 1 bar plus / minus 0.2 bar, preferably plus / minus 0.1 bar.

In this case, the later firmer object is poured in through the inner needle and the later less firmer or later with the outer needle poured more liquid object. Of course, an encapsulating object can also enclose gaseous objects at room temperature. In one embodiment, the object is designed with a recipe such that it cures more slowly or not at all on an edge layer adjacent to the film element. The liquid object is preferably poured in a so-called one-shot process. An injection, for example with one, two or more needles, is shifted simultaneously and / or briefly in time, with part of the injection taking place at least partially at the same time, the object to be packaged or the objects to be packaged in the otherwise closed receiving space by one thereafter injected filling opening to be sealed.

The device comprises a film element feed. This feeds two film elements to a molding device. The film elements are preferably fed separately. In one embodiment, the film elements are fed together. The film feed comprises an unwinding device from which the films are unwound. The film elements get into the mold from the film feed. The molding tool works according to a thermoforming process in which the film elements are heated and pressed against the mold wall by pressure in a molding tool. In one embodiment, pressure is applied by means of overpressure. In another embodiment, pressure is applied by means of negative pressure. When a vacuum acts, corresponding vacuum openings are provided in the wall of the mold, which suck the heated and thus more easily deformable film element onto the mold wall.

In another embodiment, an overpressure is brought between the film elements. The excess pressure is introduced, for example, through one nozzle or a plurality of nozzles which are brought between the film elements. The filling opening can be shaped via the nozzle or the nozzles. The nozzles which apply the excess pressure can also be used for introducing the flowable object. In another embodiment, other nozzles or filling devices are used for filling the receiving space with the object. After thermoforming the packaging, With which the sealing seam can be realized, the manufacturing device has a cutting and / or punching device with which the connected film elements can be separated so that a desired shape is realized. In addition, it is provided in one embodiment that an embossing device is provided in order to realize a reinforced sealing seam by means of embossing. Accordingly, a sealing device is provided. In one embodiment, the sealing device is designed to be integrated with the thermoforming device. In another embodiment, the sealing device is designed to be integrated with the embossing device.

A processing device is also provided. With this, the opening means can be provided in the packaging. In one embodiment, the processing device is integrated in the thermoforming device. The processing device is designed, for example, to create an asymmetrical pull tab. Here, a film element is processed accordingly, so that it is designed differently from the corresponding film element. The processing device is designed such that it forms the one film element after being connected to the other film element. In another embodiment, the processing device is designed such that it forms the one film element from the connection to the other film element.

Last but not least, the invention includes the technical teaching that in a device for producing at least one molded article with packaging described above, in particular for producing a packaged molded article, in particular a packaged article suitable for consumption, such as a food and / or a food and / or food supplement, at least one filling device is provided with at least one device described above, which is suitable for filling an object into the receiving space in a liquid and / or flowable form through a filling opening after the shaping of the receiving space. A corresponding filling device is provided for filling a flowable object. In one embodiment, this comprises at least one nozzle or the like, with which the fluid can be filled into the receiving space through the filling opening of the packaging. The nozzle has at least one filling channel through which the fluid can be brought into the receiving space. The nozzle preferably has at least two filling channels with which the filling material can be introduced. In one embodiment, the filling channels are arranged side by side. In another embodiment, the filling channels are arranged one inside the other. One of the filling channels surrounds at least one other filling channel. In this way, different fluids can also be introduced into the receiving space at least temporarily at the same time.

In one embodiment it is provided that the packaging is designed to carry out a passive flight movement, in particular a sliding and / or autorotation movement, in free fall. For this purpose, part of the film elements is designed as at least one wing, in particular at least one sliding wing and / or a rotor blade. The packaging is designed as a film packaging made of two film elements. Correspondingly, the packaging has an upper film half and a lower film half. These are interconnected. The wing forms a pull tab to open the receiving space.

Packaging in the sense of the present invention is to be understood in particular as a deliberately provided, releasable wrapping of a product. The covering encloses the object completely or only partially. The packaging preferably closes the object completely. Depending on the embodiment, the packaging is also suitable for preserving food, for example through an airtight design of the receiving space. In one embodiment, the packaging has an area for labeling the product or otherwise. For this purpose, a corresponding field or an area to be printed or otherwise provided with an identifier is provided. In one embodiment, energy-operated signal transmitters are provided for displays, LEDs, lights, acoustic signal transmitters or the like. For this purpose, the packaging has a space or section for an energy supply. In one exemplary embodiment, the energy supply takes place via solar energy. For this purpose, for example, a corresponding solar device is provided on the wing. In other embodiments, the energy supply takes place via a battery, an energy converter which converts the kinetic energy into electrical energy, or the like. The battery can be recharged, for example, by moving the packaging. In one embodiment, a centrifugal switch or the like is provided for switching a power supply. In other embodiments, areas for non-energy-driven advertising media are provided.

The packaging according to the invention has at least one receiving space into which an object can be inserted or injected. In another embodiment, the packaging comprises a plurality of receiving spaces or chambers. In one embodiment, the chambers are separated from one another. In one embodiment, the receiving spaces are separated via the common film. In other embodiments, the chambers are fluidly connected to one another. In one embodiment, the connection is designed as a temporary cover, which can be removed, for example when the film packaging is opened and / or during a movement, in particular a rotation of the packaging.

In one embodiment, the weight of the receiving space and the inserted object is higher than the weight of the rotor blade projecting from the receiving space. This weight distribution shifts the center of gravity of the entire arrangement in the direction of the receiving space in a version with a rotor blade projecting on one side, so that the packaging rotates approximately around this center of gravity. The autorotation causes the object with the packaging surrounding it to slowly fall to the ground while rotating and is largely protected from damage. This means that shock-sensitive parts, such as chocolates, can also be inserted in the receiving space. In one embodiment it is provided that at least one sliding wing is provided. In this way it is possible that the packaging with the packaged object performs a passive gliding flight, so that the packaging slowly glides to the ground. Overall, the packaging comprises means for carrying out a passive flight, that is to say sliding or an (auto) rotational movement, which enables the packaging to hit the ground more slowly. Parachutes are not covered by means of a passive flight, since they enable a pure falling movement. For example, the package is dropped from an airplane or from a distance to the ground. In another embodiment, the packaging is conveyed into the air from a floor, for example thrown or shot, so that after the transport into the air, the packaging falls into free fall. With a corresponding transition, the time of free fall is relatively short and the packaging, for example, immediately or after a minimal period of time changes to passive flight, for example a gliding flight.

The packaging has at least one wing. In other versions, several wings are formed. In addition, the packaging has at least one receiving space. In further embodiments, a plurality of receiving spaces are provided, in particular receiving spaces spaced apart from one another. The receiving spaces can be fluidly connected to one another or separated from one another.

In one embodiment, the wing is eccentric with respect to the receiving space. If there are several wings, the arrangement of the wings is symmetrical to the receiving space. In yet another embodiment, the wings are at least partially asymmetrical to the receiving space.

The receiving space and the object lying therein have a total weight GA, which is preferably a multiple of the weight GR of the wing or rotor blade. The entire packaging has a weight G. Very good autorotation results were achieved with a weight distribution in which the weight GA was seven to ten times that Weight GR was. However, other weight ratios have also led to good flight characteristics.

In this respect, one embodiment of the present invention provides that the weight GA is a multiple of the weight GR, preferably about 1.5 times to about 15 times, preferably about 5 times to about 12.5 times and most preferably that is about 7 times to about 10 times the weight GR.

Yet another embodiment of the present invention provides that the packaging is made up of several parts, in particular with a separate wing and a separate receiving space, which are detachably or firmly connected to one another. In this way, for example, the receiving space and the wing can be produced in separate process steps. For example, it is possible to receive the object in the receiving space and then to connect the receiving space to the wing. In another embodiment, the packaging is carried out in one packaging step. This means that the article is packed simultaneously and / or in one process step with the manufacturing step of the packaging.

In a further embodiment of the present invention it is provided that the receiving space is partially integrated in the wing. In one embodiment, the receiving space projects into an interior of the wing. In another embodiment, the receiving space runs on the outside of the wing. In one embodiment, the receiving space is completely closed off from an external environment. In another embodiment, the receiving space is at least partially open to the outside environment. For example, the receiving space is spanned solely by holding means for holding an object to be packaged. In one embodiment, the wing is directly adjacent to the receiving space. The wing and the receiving space are preferably formed together by means of a film element or a second assigned film element. The wing part and the receiving space part are formed in one piece.

Another embodiment of the present invention provides that the packaging, in particular the receiving space and / or the wing, is / are sealed, in particular airtight and / or gas-tight. Through a tight receiving space or, if the receiving space is integrated into the wing, for example, through a tight wing, a liquid, a gas and / or a powder can thus also be packaged with the packaging. In particular, the packaging is designed such that it can withstand overpressure. In this way an air cushion of the packaged item can be realized with the packaging. In particular, the packaging is gas-tight up to pressures of preferably about 2 MPa, in particular also up to about 1 MPa, most preferably up to about 0.5 MPa.

The packaging can advantageously be formed from at least two packaging halves, which can be opened and closed or otherwise connected to one another via a joint such as a film hinge or another connecting element. Such packaging can have a locking element on the side opposite the hinge, which allows secure locking. A plurality of connecting elements and / or latching elements are preferably provided. Additional locking or locking elements are to be provided. The locking elements or connecting elements are designed for reclosing the packaging. In one embodiment, the articulation is formed by a reinforced sealing seam. This is reinforced, for example, by means of an embossing.

In one embodiment it is provided that the packaging is made in one piece. In this way, the packaging together with the receiving space and the wing can be produced together in one production step. This eliminates the need for complex assembly steps, for example connecting the wing to the receiving space. The article to be packaged is preferably packaged when the one-piece pack is produced.

It can be advantageous to manufacture the packaging from a dimensionally stable biomaterial, in particular from a renewable raw material. For higher stability requirements, the packaging can also be made from a largely dimensionally stable plastic as a one-piece injection molded part. In one embodiment it is provided that the material for the film elements has a higher melting point or a higher melting temperature than the liquid object. In this way, the film elements can be deformed by means of a thermal process and an object which has previously been melted can be filled into the packaging without the latter being deformed again or being effectively damaged by the melted object

A preferred embodiment of the present invention therefore provides that the packaging, the receiving space and / or the wing are made of a thin-walled, dimensionally stable material, in particular biomaterial, including textile materials, fabric materials, viscose materials, cellulose materials, starch, corn starch, potato starch, foil, metal foil, Plastic film, paper film, film composite, hybrid materials, water-soluble materials, compostable materials, biodegradable materials, rice, corn or gelatin, PLA is trained. In other embodiments, corresponding composite materials or mixtures of these compounds are provided.

The receiving space of the packaging serves as a mold for the filling material. Correspondingly, objects can be molded directly into the packaging and do not have to be molded and then packaged in separate steps. In one embodiment, the packaging is coated on the inside of the receiving space for direct shaping of the object in the packaging, so that undesired adherence of the object is avoided. The inserted object is completely encompassed by the packaging surrounding it and held in its position relative to the packaging. This is also supported by an undercut. The undercut is designed such that it forms a narrowing and / or predetermined breaking point for the object to be packaged at the transition from the receiving space to the undercut.

Therefore, one embodiment of the present invention provides that the packaging for holding a candy, a liquid, a powder, a gas or another object with a predetermined external dimension such as a predetermined external diameter has a receiving space with at least approximately the same internal dimensions or the same internal diameter. In one embodiment, fillers are additionally provided in the receiving space, possibly in a separate chamber, with which the remaining free space between the object and the receiving space is at least partially filled. In one embodiment, an overpressure is generated in the receiving space. In another embodiment, a part of the receiving space is not filled with the object but with the filler, for example also air. The receiving space is preferably at least 85%, more preferably at least 90%, even more preferably at least 95% and most preferably 99% filled with the object.

It is also advantageous if the protruding rotor blades have a length or a largest dimension that is more than three times the diameter or the largest dimension of the receiving space. In addition, it is advantageous to dimension the width of the rotor blades so that it is in the range from one to two times the largest receiving space dimension.

The receiving space can form any shape. A spherical shape is preferably provided, although other shapes are also conceivable. A polyhedron form is most preferred.

The at least one wing, in particular the at least one rotor blade, preferably projects laterally from the receiving space. Yet another embodiment of the invention provides that the packaging has transverse stiffening webs at least in the area of the wing, in particular the rotor blade. The packaging can have approximately the shape of a flying seed - a samra - like a maple flying seed or the asymmetrical shape of the flying seed of the tree of heaven (lat .: Ailanthus altissima). It when the packaging is formed from a thin-walled material, it is particularly advantageous to form with transverse ribs for stiffening the wing surfaces, in particular the rotor surfaces. If the packaging is made of a thin-walled plastic film, these transverse ribs can be produced by means of corresponding linear heating elements during the molding process. Of course, other manufacturing processes such as upsetting, folding, crumpling or the like can be used. One embodiment therefore provides that the packaging has transverse stiffening webs at least in the area of the wing, in particular the rotor blade. In another embodiment, an edge of the film elements is reinforced with regard to its thickness, so that increased swirling can occur here.

In addition, it is provided in one embodiment of the present invention that the receiving space has opening means for easier opening, for example a perforation, a tear aid, a joint, a material weakening or the like. This makes opening easier for the user, particularly in the case of tight packaging. Unintentional opening, for example due to environmental influences, is also prevented.

In a further embodiment of the present invention it is provided that a filler is provided in the receiving space, which at least partially surrounds the object to be packaged, comprising liquids, gases, solids, in particular a pressurized gas such as air, small solids and the like. In this way, even heavier objects can be packed with the packaging according to the invention. For this purpose, a gas that is lighter than air can be introduced into the receiving space as a filler, similar to the functional principle of a zeppelin. A buoyancy force is then realized by the filler. In addition, suitable fillers can improve the impact properties when landing on the ground, so that a packed object is additionally protected. The fillers can be made from any material, in particular from the same material as the packaging. In this way, for example, packaging residues that arise during the manufacture of the packaging can be used as fillers.

Yet another embodiment of the present invention provides that holding means are provided on the wing and / or the receiving space in order to hold the object to be packaged on the wing or in the receiving space. To prevent movement of the packaged object during passive flight, for example, holding means are provided which prevent unwanted movements. The object is, for example, positively and / or non-positively held in the receiving space or on or in the wing. In this way, for example, part of the object can be used as a stabilizing means in the wing and / or the receiving space, for example the style of a lollipop. In one embodiment, for example, a straw is attached to the wing, so that the wing is reinforced by the straw and / or a flow guiding means is formed by the straw. If a liquid is packaged in the receiving space and / or the wing, that is to say in the packaging, the straw is designed to be removable from the wing and the liquid can be removed from the packaging via the straw.

In addition, it is provided in a further embodiment of the present invention that the wing has flow guide means, comprising a trip wire, nozzle elements, ribs, recesses, projections, passages and the like, in order to improve the flight properties of the packaging. By means of such means, the flow around and / or flow against the wing is adapted to the corresponding situation. If such flow guide means are provided, swirls, laminar flows, turbulent flows, stalls and the like can be used in a targeted manner, for example.

It is also provided that the packaging of the object takes place in one step with the production of the packaging, in particular simultaneously, or that the packaging of the object takes place in a separate step from production of the packaging and / or the receiving space and / or the wing, in particular in succession ,

In one embodiment of the invention, packaging can be produced from two plastic films. The two plastic films are pressed, pressed and / or welded onto the receiving space on both sides by means of a tool. In this embodiment, the tool comprises two tool halves that are moved against each other. The film is fed, for example, by advantageously synchronously rolling two rolls. An object is advantageously to be inserted either immediately during the manufacturing process or later in the receiving space.

In another embodiment, the film is fed from a roll only. Advantageously, it is not necessary to have two rolls running synchronously, which is very difficult and prone to errors in the case of film packaging which is to be as symmetrical as possible on both sides.

It is also provided that in the case of a packaged goods with packaging, it is provided that the packaging is designed as packaging according to the invention and the packaged goods are held in the receiving space, for example via an undercut.

Preferably after the shaping of the receiving space, the object is filled into the receiving space through a filling opening in a liquid and / or flowable form and the filling opening is closed by means of a seal weld.

Further preferred is a manufacturing device with at least one film element feed for feeding and / or conveying film elements, with at least one molding device, which deforms supplied and overlapping film elements under the influence of temperature in at least one molding tool, so that a receiving space is formed between the film elements, and with a sealing device, which at least partially seals the receiving space by means of at least one sealing seam.

The object to be filled in preferably comprises two fluids that are liquid during filling, the first fluid and the second fluid being introduced into the receiving space such that the first fluid at least partially surrounds the second fluid in the receiving space and the second fluid thus a core for the first fluid forms.

One embodiment provides a packaging, in particular a film packaging with a bubble-like receiving space, in particular a blister packaging comprising: at least two foils connected along an at least partially circumferential, common sealing edge, in particular two foils connected to one another by means of at least one seal welding, and at least one receiving space for receiving of an object to be packaged between the foils, the two foils protruding from the edge region of the latter as a tear-open tab with which the two foils can be separated from one another along the tear-open tab and at least partially along the receiving space along a tear-open direction in order to access the To realize the receiving space, wherein the extension of the tear tabs in the tear direction is larger than the extension of the receiving space in the tear direction.

Furthermore, an embodiment provides a packaging with an object packed therein, in particular a packaging with an object filled in its receiving space in a liquid phase, comprising packaging with a receiving space, wherein in the receiving space an object introduced in a liquid phase and to a dimensionally stable object cured object, in particular a food and / or food, is arranged. Furthermore, one embodiment provides for the production of a packaged object having a shape, comprising the steps: filling the object into a shaping receiving space of a packaging in a liquid phase and curing the object in the packaging so that it changes into a dimensionally stable phase.

A further embodiment provides a method for producing a packaging, in particular a film packaging with a bubble-shaped receiving space, comprising the steps: connecting at least two films along a circumferential, common seal edge, in particular with at least one seal weld, at least one edge area being left unconnected , and forming a receiving space for receiving an object to be packaged, in particular through the edge region, at least one undercut cavity being formed in the receiving space adjacent to the unconnected edge region, in which the object to be packaged is stable. The undercut cavity is also referred to as undercut for short.

It is further provided that at least one edge region of the foils (elements) is left unconnected, in particular in order to fill the receiving space through it.

The receiving space is preferably symmetrical to the film plane. The receiving space preferably has a profile, that is to say in the film elements, in particular a three-dimensional profile. This means that the receiving space is defined by foil elements that have a profile with corresponding projections and recesses. The receiving space is thus itself designed as a mold for the molded object to be cast.

It is preferred that the packaging of the object takes place in one step with the production of the packaging, in particular simultaneously.

In one embodiment it is provided that when the packaging with the packaged object is produced, the packaging of the object in a separate step from one Manufacture of the packaging and / or the receiving space and / or the wing, in particular one after the other.

According to the invention, a manufacturing and packaging method of soft capsule products with liquid or semi-solid contents is thus provided. Improved packaging and soft capsule manufacture is provided. The packaging and the soft capsule with filling material are produced in an optimized process. Similar to the blow molding of beverage bottles (PET), the new manufacturing and packaging process is used for forming (heating, molding). In the next step, the product is filled into the packaging. After the filling process, the packaging is sealed and further shaping steps are carried out. In addition to reduced effort (time saving, less handling), considerable resource conservation is achieved. This significantly reduces energy consumption. A single-variety packaging is provided. The energy-intensive hard aluminum foil according to the prior art is substituted. It is preferable to use a type-specific packaging that requires fewer separation processes or that is biodegradable. At least one predetermined breaking point is provided. In the sense of the invention, the predetermined breaking point also includes a predetermined breaking point, that is to say a point at which the film elements bend more easily when a force is applied than at other points on the packaging, in particular in the area of the receiving space. The object and / or the corresponding receiving space are preferably wedge-shaped with a more pointed section in the area of the filling opening and a thicker area in the area of the wing-like edge area.

In one embodiment it is provided that the tear-open tab, viewed in the sealing seam plane, does not lie in an extension (180 °) to the filling opening, but rather transversely to it. A main direction of the filling opening in the sealing seam plane includes an opening angle in the sealing seam plane with the tear-open direction of the tear tab, which is measured counterclockwise in the range 5 ° to 355 ° without the range of 180 ° +/- 5 °. The angle is preferably in the range from 5 ° to 40 °, 50 ° to 175, 185 ° to 310 ° and 320 ° to 355 °. The angle is more preferably in a range from greater than 50 ° to less than 310 ° without the range 180 ° +/- 5 °. In a preferred embodiment, the angle is in a range from 60 ° to 160 ° and / or 200 ° to 300 °. The tear-open tab is preferably located transversely to the filling direction on an opposite side, that is to say at angles greater than 90 ° and less than 270 °.

In a further embodiment, the shape of the pull tab is curved or curved. In particular, there is an edge of at least one pull tab, in particular both interacting tear tabs curved or curved. The tear-open tabs are preferably asymmetrical or not congruent, so that part of one tear-open tab is uncovered by the adjacent other tear-open tab. Preferably, all edges of the tear tabs are curved or curved. In one embodiment, the uncovered area is in a range of greater than 10% of the total area of the tear tab, more preferably greater than 20%, still further greater than 30%, further greater than 40%, more preferably greater than 50% and most preferably greater than 60% of the entire uncovered area. The narrower tear tab is preferably formed with a main extension in the tear direction, that is to say as an elongated tear tab. Due to the large proportion of the uncovered area, a relatively large area for imprints such as warnings, advertising and the like on the tear tab is possible. Due to the narrow, elongated shape, the narrower pull tab is sufficiently easy to grip and easy to handle. The uncovered area is preferably greater than 60% of the total tear tab area.

In different views and different degrees of detail, the figures show different embodiments of a packaging 100 which is formed from two overlapping film elements 110. The two overlapping film elements 110 form a receiving space 120 between them, which is formed by thermoforming between the film elements 110. Around the receiving space 120, the packaging has an edge area 130, which is formed by the film elements 110 and in which the film elements 110 adjoin one another without a gap. A part 131 of the edge area 130 is formed uniformly around the receiving space 120 and another part 132 extends away from the receiving space 120 like a wing. The transition between the two Parts 131 and 132 are flowing or continuous, so that here a transition area 133 is formed, in which a clear separation between parts 131 and 132 is not shown exactly defined. In other embodiments, a clear separation without transition area 133 is provided. The packaging 100 has opening means 200 for easier opening of the packaging 100. In the exemplary embodiments shown here, these are embodied integrated in the packaging.

Figure 1 shows a schematic plan view of an opened package 100 with an opening means 200 designed as a peel-off unit 210. The peel-off unit 210 has a part 132 of the edge area 130 which is designed as a tear-open tab 140. The pull tab 140 is designed as an asymmetrical pull tab 141. In this case, the film elements 110 adjoining one another without gaps are designed to be congruent. A part 132 is made narrower so that an area of the other film element 110 is visible in the folded state. This asymmetrical design of the pull tab 140, 141 results in a simplified peel-off, that is to say a simplified separation of the film elements 110. In the embodiment shown, the part 132 is longer in its longest extension than the receiving space 120 in its longest extension, both viewed in the plane of the film, ie in the contact plane of the film elements 110. This results in a favorable force ratio in peel-off. The film elements 110 are connected to one another via a sealing seam 150. In this case, the sealing seam is not formed over the entire film element 110, but rather only along an edge of the film elements 110 Fig. 1 In the illustrated embodiment, a reinforced section of the sealing seam 150 or a sealing seam reinforcement 151. During a peel-off process, the two film elements 110 remain connected to the sealing seam reinforcement 151 in the opened state, so that the reinforced sealing seam 151 functions as a joint 155 between the film elements 110. The sealing seam 150 is formed all the way round on the wider film element 110. In the narrower film element 110, the sealing seam 150 is not formed all the way round, but rather is interrupted. The interruption is formed on part 132. This results in easier opening and less material consumption.

In the Fig. 1 The packaging 100 shown has approximately the shape of a maple flying seed when folded. The part 132 protrudes in the form of a rotor blade from the receiving space 120, which ensures that the packaging 100 designed in this way executes an autorotation in free fall and slowly floats to the ground.

Fig. 2 shows a schematic plan view of an opened package 110 with an opening means 200 comprising a peel-off unit 210 with another embodiment of a tear-open tab 140. The two parts 132, which form the tear-open tab 140, are approximately congruent, so that they are folded together lie congruently on top of each other. In this way, a symmetrical pull tab 142 is formed. The sealing seam 150 is designed for a simplified peel-off on one film element 110 different from that on the other film element 110. Thus, a user can separate the two film elements 110 more easily.

The Fig. 3 shows the embodiment according to another schematic view Fig. 1 , The receiving space 120 extends out of the film plane. A sealed filling opening 160 lies approximately on the side of the receiving space 120 opposite the side of the tear-open tab 140. The filling opening 160 is arranged offset to a gravity line (not shown here). Furthermore, the filling opening 160 is closed by means of the sealing seam 150, the sealing seam 150 having the sealing seam reinforcement 151 to form a joint 155, here in the manner of a film hinge. The film elements 110 form an asymmetrical pull tab 141.

The Fig. 4 shows the embodiment according to another schematic view Fig. 3 in a partially opened condition. The film elements 110 are made of a bendable material or have a corresponding material thickness, so that the film elements can be bent. A peel-off process is shown in which the film elements 110 are separated from one another in the area of the tear-open tab 140, the sealing seam 150 also being separated in this area. The film elements are bent, here elastically bent. The tear tab 140 is formed in one piece with the part 131 that defines the receiving space 120. The sealing seam 150 extends over the parts 131, 132 and possibly 133. By separating the sealing seam 150 during the peel-off, the receiving space 120 is opened and access to the interior thereof is ensured.

The Figure 5 shows the embodiment in a schematic plan view Fig. 1 in a collapsed condition. The position of the sealed filling opening 160 is clearly shown here. This lies offset to a line of gravity S of the packaging. The filling opening 160 is closed with a sealing seam 150, which has a sealing seam reinforcement 151, here in the form of an additional embossing. The sealed filling opening 160 protrudes from the peripheral edge of the packaging, that is to say the filling opening 160 does not end flush with the remaining edge. The filler opening protrudes a few millimeters in the exemplary embodiment, by less than 3 millimeters in the present example.

This protrusion enables a simpler filling process. In addition, the protrusion of the filling opening 160 is required for the sealing seam reinforcement 151. The packaging 100 is approximately triangular in the film plane. The receiving space 120 is arranged at a corner region of this triangular shape, adjacent to the filling opening 160. The filling opening forms a filling channel 161 along the direction K, which is formed obliquely to the gravity line S here. The direction K is approximately at an angle of 45 ° to the gravity line S. The channel or its direction K is arranged such that when the package 100 is opened on the tear-open tabs 140 it points approximately in the direction of gravity, that is, in the direction of the center of the earth , Other angles are possible.

The Fig. 6 shows the embodiment in a schematic, partially sectioned top view Fig. 5 , It can be clearly seen here how the sealing seam 150 surrounds the receiving space 120 in the film plane, in order to seal the receiving space 120 formed between the film elements 110. The filling opening 160 is designed approximately as an oval channel 161, which is closed to the outside by the sealing seam 150 and the sealing seam reinforcement 155. Here, the sealing seam 150 around the filling opening 160 has the sealing seam reinforcement 151 not only on the protruding part but also on the edge located laterally next to the filling opening 160.

The Fig. 7 shows a schematic perspective view of an embodiment of the package 100 with an undercut 170. The package 100 essentially corresponds to the embodiment Fig. 6 , The filling opening 160 is fluidly connected to the receiving space 120. The channel 161 of the filling opening 160 has an undercut 170, here in the form of a depression or depression 171. In this way, a retaining means is formed which, when the package 100 is opened, retains an object which is injected into the receiving space 120 and the filling opening 160 and cured there, so that it does not inadvertently get out of the opened package. The undercut is formed here in the area of the filling opening 160. A tear opening or a direction for removing an object is defined by the reinforcement of the sealed seam. This takes place in a direction in which the filling opening or its channel extends.

The Fig. 8 shows a schematic perspective view of a package 100 with a pop-off unit in a first state. The Fig. 9 shows the packaging 100 in a schematic perspective view Fig. 8 in a second state. The Fig. 10 shows a schematic perspective view of the packaging Fig. 8 respectively. Fig. 9 in a third state.

Is shown in the Fig. 8-10 schematically the opening of the package 100 at a pop-off. In the pop-off process, the film elements 110 are bent on both sides by the receiving space 120 together in a common direction, so that the film element 110 comes under tension in the region of the receiving space 120. If the tension is sufficiently high, the film element 110 bursts in the area of the receiving space 120 and releases the receiving space. In order to support this process of pop-off opening, an opening means 200 in the form of a predetermined breaking point 201 is provided in one embodiment. The predetermined breaking point 201 is formed, for example, as a material thinner in a film element 110, preferably in the area of the receiving space 120 or in the transition from the receiving space 120 to the gap-free film element 110. In the present case, the sealing seam 150 has a sealing seam weakening 153, so that the sealing seam 150 opens in this area. The film elements 110 remain reusable in this way.

The Fig. 11 shows a schematic perspective view of another embodiment of the package 100 in the closed state. In this embodiment with a pop-off unit 240, a predetermined breaking point 201 in the form of a slot 202 is provided as opening means 200 on both sides next to the receiving space 120 in the film elements 110. With a corresponding force, the opening of the packaging 100 is supported by this predetermined breaking point 201.

The Fig. 12 shows a schematic side view of a further embodiment of the packaging 100 in a closed state. The packaging 100 essentially corresponds to that in FIG Fig. 8-11 Package 100 shown and can be designed with or without slot 202. As a further opening means 200 in the embodiment of FIG Fig. 12 a recess or depression 203 is introduced in the form of a depression in a film element. This depression 203 functions on the one hand as an undercut 170. On the other hand, this depression 203 is provided for the application of force, for example by means of a finger. A force can be steered through the trough 203. Together with a suitably designed sealing seam 150 with corresponding sealing seam reinforcements 151 and corresponding sealing seam weakenings, a targeted opening of the packaging 100 can thus be realized. The Figures 13-15 show different embodiments of sealing seams 150.

The Fig. 13 shows a schematic, partially sectioned top view of a package 100 with a first embodiment of a sealing seam 150 Fig. 14 shows a schematic, partially sectioned top view of a package 100 with a second embodiment of a sealing seam 150 Fig. 15 shows a schematic, partially sectioned top view of a package 100 with a third embodiment of a Sealing seam 150. The sealing seam 150 extends circumferentially around the receiving space 120.

In the in Fig. 13 In the illustrated embodiment, the sealing seam 150 has two sealing seam reinforcements 151. These are arranged on different sides of the receiving space 120 and are spaced apart from one another by the sealing seam 150. Starting from the filling opening 160, a line L1 is drawn in the filling direction L1. A second line L2 is drawn approximately perpendicular to this. In this way, the receiving space 120 is divided into four quadrant-like areas. In the film plane, the first sealing seam reinforcement 151 is in a half past ten to twelve o'clock position. The sealed fill opening 160 is about two to four o'clock. The second sealing seam reinforcement 151 is located approximately at six to eight thirty. The sealing seam 150 is arranged in the other areas around the receiving space 120. This arrangement results in a targeted opening in a popp-off process. A slot 202 is provided on each side next to the filling opening 160. The filling opening 160 can be opened via this, as in FIG Fig. 15 shown.

In the in Fig. 14 In the illustrated embodiment, the sealing seam 150 has two sealing seam reinforcements 151. These are arranged on different sides of the receiving space and are each spaced apart from one another by the sealing seam 150. Starting from the filling opening 160, a line L1 is drawn in the filling direction L1. A second line L2 is drawn approximately perpendicular to this. In this way, the receiving space 120 is divided into four quadrant-like areas. In the film plane, the first sealing seam reinforcement 151 is in a half past ten to twelve o'clock position. The sealed fill opening 160 is about two to four o'clock. The second sealing seam reinforcement 151 is located approximately at six to eight thirty. The sealing seam 150 is arranged in the other areas around the receiving space 120. This arrangement results in a targeted opening in a popp-off process.

In the in Fig. 15 In the illustrated embodiment, the sealing seam 150 has the two sealing seam reinforcements 151. These are arranged on different sides of the receiving space 120 and are spaced apart from one another by the sealing seam 150. Starting from the filling opening 160, a line L1 is drawn in the filling direction L1. A second line L2 is drawn approximately perpendicular to this. In this way, the receiving space 120 is divided into four quadrant-like areas. In the film plane, the first sealing seam reinforcement 151 is in a half past ten to twelve o'clock position. The sealed fill opening 160 is about two to four o'clock. The second seal reinforcement 151 is about six to eight-thirty. The sealing seam 150 is arranged in the other areas around the receiving space 120. This arrangement results in a targeted opening in a popp-off process. The film element 110 in the area of the filling opening 160 between the slots 202 is cut out here, so that, for example, a liquid or a powder can thereby be moved out of the receiving space.

The Fig. 16 shows a schematic, partially sectioned top view of another embodiment of a package 100 with another embodiment of a sealing seam 150 Fig. 17 shows in a schematic perspective view, the embodiment of Fig. 16 , The Fig. 18 shows the embodiment in a schematic side view Fig. 17 , In the Fig. 16-18 A packaging 100 is shown which has a rather oval shape in plan view. The receiving space 120 is approximately circular in the film plane. The sealing seam 150 for closing the receiving space 120 runs correspondingly circular in the film plane. On the area of the sealing seam 150 facing the part 132, the sealing seam has a sealing seam reinforcement 151. The sealing seam reinforcement 151 is approximately semicircular. This is followed by the non-reinforced sealing seam 150, which also closes the area of the filling opening 160. A recess 203 is provided in the film element 110 in the area of the receiving space 120 and also functions as an undercut 170. A packaged object can be pushed in the direction of the filling opening 160 by the application of force via the recess 203. As a result of this force, the sealing seam 150 opens in the area of the filling opening 160 and opens up the receiving space 120. At the sealing seam reinforcement 151, the sealing seam 150 remains closed and thus forms a joint 155. The opening takes place here in a squeeze-off procedure. This means that the packaging has a squeeze-off unit (trough, sealing seam reinforcement, with which an object can be removed from the receiving space 120 by applying force in the form of a "squeeze". The removal takes place by a linear movement of the object, one rotational movement of the object or a combination of both.

The Fig. 19 shows a schematic representation of a pop-off process / squeeze-off process of a package 100. Here, the two sealing seam reinforcements 151 specify a possible direction of movement of the object in the package 100.

The Fig. 20 shows the squeeze-off / popp-off process in another view Fig. 19 , As can be seen here, the object is pushed out of the receiving space 120 by a linear movement.

The Fig. 21 shows the squeeze-off / popp-off process in yet another view Fig. 20 , The side view shows how the object is moved along the film plane.

The Fig. 22 shows a schematic representation of another squeeze-off / popp-off process of a packaging 100. Here, the movement of the object is not rotational, but rotational. The sealing seam 150 is designed accordingly so that it only allows opening via a rotary movement, but not via a translatory movement. The flow of force is controlled in a targeted manner by means of a defined recess and a corresponding sealing seam.

The Fig. 23 shows a schematic perspective view of a package 100 in another embodiment. Here, the film elements 110 are only shown as a receiving space without a protruding edge area. The trough 203 is arranged here on a surface of the film elements 110 which is formed obliquely to the film plane in the region of the receiving space 120. The trough 203 acts both as an undercut 170 and as a force introduction aid for the targeted application of force. The oblique arrangement directs a force component in the direction of the filling opening.

The Fig. 24 shows the packaging 100 in another schematic perspective view Fig. 23 and the Fig. 25 shows the packaging 100 in a schematic side view Fig. 24 ,

The package 100 is designed as a dimensionally stable, foldable and foldable package, which can be made of plastic or another dimensionally stable material. The two halves of the packaging 100 are pivotally connected to one another via the hinge designed as a film hinge. The two bulged areas of the film elements 110, which form the receiving space 120, enclose the receiving space 120, from which the part 132, for example in the form of a rotor blade, projects.

For example, an opening notch is formed between the receiving space 120 and the rotor blade, which facilitates the opening of the receiving space 120. Both halves can be connected via a sealing seam 150 designed as a welded or glued seam. In addition, a stiffening wire can run in the longitudinal direction of the rotor blade. A locking element, not shown here, can be provided on the side opposite the film hinge be that releasably connects the two rotor blade halves together in the closed state.

In order to increase the rigidity of the rotor blade, in one embodiment laterally transverse stiffening webs are formed on it, which can be designed as correspondingly thick-walled ribs in a plastic packaging. Corresponding stiffening webs can also be formed only by a linear melting by exposure to heat or by embossing.

The object to be inserted into the receiving space, for example a candy, can be inserted into the receiving space during the manufacturing process or even later. The mold halves are moved against each other during the thermoforming process in order to shape the packaging. The film webs are rolled off as synchronously as possible from two rolls and can be applied against the shape of the mold halves by means of vacuum or negative pressure or positive pressure. The surrounding outer edges are welded together by exposure to heat. Another embodiment of the device for producing a packaging from two plastic foils provides that foil webs are only unrolled from a roll. This has the advantage that no two roles have to run synchronously with each other. In one embodiment, the packaging 100 has an asymmetrically arranged receiving space, from which a longer and a shorter rotor blade each protrude. In one embodiment, the packaging is formed from an inelastically deformable film, preferably from a metal film. An elastic film is preferred. Accordingly, it is possible to manufacture the packaging 100 from a biomaterial or a plastic material. The receiving space is preferably designed such that an object can be inserted in it in a self-clamping manner. In principle, however, the receiving space can also be provided with a cover or envelope which encloses the receiving space.
