The field of technology

The present invention relates to the field of stretchable packaging and to the processes of its use and its manufacture.

Description of a technical problem

Packaging for food, pharmaceutical, plant protection and various chemical products, preferably for pre-packaged products, often involves a large amount of empty space during the packing and packaging phase of the product, for example during storage, transport and delivery, both on the page the manufacturer, the seller as the consumer, at the time of distribution, at the time of sale, for example on the sales or display shelves, and at the stage of preparation of a food, pharmaceutical, plant protection and / or chemical product for end use or application of the product. This blank space is intended either to add other ingredients for the preparation of such an end-use product or solely for the purpose of packaging or packaging.

For example, such empty space in the packaging most often appears in the packaging or packaging. packaging of food products consumed with rapid food preparation, which are therefore most preferably in the pre-prepared state and must be prepared before being ingested, most often directly from the packaging itself, so that they can be prepared at the time of ingestion Adds an ingredient such as liquid, most commonly water, juice, milk, sauce, dressing or other similar liquid or semi-liquid food, to the empty space, and may also be solid food. Similarly, such empty space in packaging is also used in packaging or packaging. packaging of pharmaceuticals, plant protection products and certain chemical products.

This empty space means additional volume of packaging and product at all stages of product life and contributes to the increased consumption of raw materials and materials for packaging, especially for its protective packaging, for example during storage, transport, distribution and delivery, and thus to higher packaging or packaging costs. packaging, and above all to greater space consumption and higher costs during the packaging, storage, transportation, distribution, delivery and sale of packaging or packaging. packaging products.

Therefore, the present invention seeks to solve the technical problem of reducing the empty space in packaging and thereby reducing the consumption of raw materials and materials in the production of packaging and reduce space consumption, thereby contributing to reducing costs during packaging, storage, transportation, distribution, delivery and sale of packaged products , which are, inter alia, food, pharmaceutical, plant protection, chemical and other similar products.

Description of the prior art

Patent US 8556099, published December 15, 2011, and granted October 15, 2013, describes a telescopically extendable or foldable container, respectively. preferably a beverage container consisting of several horizontal annular segments, respectively. rings which are one lower cylindrical ring, one or more middle cylindrical rings, and one upper cylindrical ring, where each segment or. a ring loaded via another wider than the second segment, which lies below the wider segment in the folded phase of the container. The precise alignment and fixation of these segments in the folded and fully extended phase is achieved by notches and locking buckles on the surface of these segments. The described container is either plastic, paper, cardboard or durable and durable materials. Such construction achieves a reduction in the volume of the container by folding during storage and transported a, including the user carrying the container in a suit pocket or bag, as well as by throwing it away to reduce the volume of waste, and by increasing the volume of the container during use. Preferably, the containers are described in dimensions that fit into the jars and bottles in the vehicles.

US Pat. No. 3,131,845, published and granted May 5, 1964, describes containers with openings in the form of pots with a side wall extending outwards from the bottom of the pot up to the opening. They are intended for single use for drinking beverages or as containers, covered with lids, for storing beverages, ice creams and similar products and are made of synthetic plastic materials, such as n. BC polystyrene. Because such containers are often transported stacked into one another before use, they are often wedged together, especially by the side walls. This patent describes the construction of a bottom crucible having in the center a bulge of various shapes extending inwardly into the crucible space and, if necessary, with the addition of molding elements along the protrusion and with a certain angle of inclination of the lateral wall of the bulge relative to the plane of the bottom of the crucible, where such a protrusion of pots. One embodiment illustrates a crucible with a horizontally corrugated or ribbed sidewall in the upper half of the crucible to reinforce the crucible.

U.S. Patent No. 4,492,313, published and granted Jan. 8, 1985, and U.S. Pat. No. 32379, published and published March 24, 1987, describes folding or compressible plastic containers, preferably bottles made of very strong flexible plastic, such as n. BC Acrylonitrile and similar plastics approved by the Food and Drug Administration (FDA) having a bottom, aperture top, and a cylindrical side wall that connects the bottom to the top, with the side wall at least it consists partly of a series of successively strung circular folds or folds of alternately larger and smaller diameters formed by a wall of lower thickness than the thickness of the side wall, and with tapered sections including alternately shorter sections and longer sections where shorter sections have larger tilt angle and longer sections smaller than tilt relative to the vertical axis of the container. Further, such container includes an additional container which is attached to the bottom of the compressible container and extends up to a certain height of the compressible container in order to keep the compressible container in the compressed phase and at the same time to maintain the container. The described container is compressible up to about 50% of the volume of the container in the vertical direction due to the compression of the folds together or. wrinkle folds. The aim of such a reduction in the volume of the container is primarily to reduce the air space at the top of the container by consuming the beverage in the container, which is crucial for carbonated soft drinks, where dissolved carbon dioxide evaporates from the beverage into the air space above it within a few hours of opening the container. the drink loses its original taste. Additionally, the compressibility of the container also reduces the storage volume of empty containers before returning to reprocessing. A process for manufacturing such containers is also described, which includes a two-step container design process and an additional process for folding the side wall. In a two-step process, the injection molding process of a pre-shaped container in the form of plastic tubes is followed by a process of pre-mold heating above the temperature of thermal deformation of the plastic and blowing and extending the containers to a final volume in the container mold. After this expansion, before removing the container from the mold, the formation of the sidewall folds is carried out by injecting additional air or high pressure nitrogen into the container at one time, which causes the expanded sidewall to be pushed into the recesses of the mold, thereby forming lateral folds. the walls. Suddenly elevated pressure further extends the lateral wall and makes it thinner, especially over the inner circular edges of the mold where folding points or joints are formed. lateral wall folding sections. Such wrinkling of the side wall makes the container easily and quickly lost when liquid is removed. The folds of the side walls also allow the container to lean more than one side to the other, thus simulating the shape of the tube for easier pouring of liquid into it.

Patent US 3850361, published and granted Nov. 26, 1974, describes a disposable plastic crucible consisting of an inner wall and a ribbed outer wall, where the ribs are located in the middle of the height of the outer wall of the crucible and have both outer and inner walls at the passage from the bottom pot in the side wall step-shaped. These outer wall ribs and the step shape are intended to facilitate the gripping of the pots and to prevent the pots from getting stuck when stacked into one another.

Patent US 3434589, published and granted Mar. 25, 1969, describes an expandable and compressible container. a container for pharmaceutical tablets, pellets or powder granules into which water is poured in the expanded state. It is made of durable plastic material and is intended for carrying in handbags and for single personal use. The described container has a bottom and a removable cap and an annular wall, preferably of polystyrene, polyurethane, polyethylene or polypropylene film or sheets, which are produced by injection molding, vacuum molding, injection molding or injection molding. The container has a circular cross-section. Its side wall is either vertically stretched or compressed, forming harmonics-like folds. The compressed form is held in place by a cover band. The described container may be without built-in tablets, but may have two wells in the bottom of the container, with soluble tablets or pellets embedded in its bottom.

Patent Application US 20050258225, published November 24, 2005, describes a disposable paper crucible having a cylindrical shape, a bottom and an opening at the top, and a side wall of the container, made by vertical zigzag folding for the purpose of thermal insulation of the crucible for safe transport of the crucible, in which has hot or cold contents, liquid or. drink as n. BC coffee. In the crucible, at least one surface is moisture-repellent, whether coated with a polyethylene film, preferably internal for fluid tightness or external. The folds in the tops and valleys are either rounded or pointed and of equal length of the folds of the folds. Such construction achieves minimal contact of the user's hand with the crucible, which is only over the tips of the folds of the folded surface of the crucible, where air flows between the outer tips and valleys of the creeks, which offers additional thermal insulation. The process of folding paper surfaces for making pots is also described, with paper materials having a temperature resistance of up to about 93.3 ° C being selected.

EP 287170, published October 19, 1988, describes the vertical or axially expandable and compressible container or. a container or bottle for storing a substance contained in such a container (such as concentrated fruit juices, frozen juice concentrates, partial melt of frozen concentrates, dry powder concentrates such as teas), in a compressed container and then dilution of the substance in the expanded container. The container is designed to be easier to squeeze and stretch and has one handle at the bottom and top of the container. The key to this is the pleated wall of the container with a special shape of folds that are rounded or. rounded with rounded or. Unlike similar containers of the prior art with circular sidewalls constructed of straight-wing folds. In addition, the wrinkles are shaped such that their diameters are narrowed in series up or down in series along the axis. container vertices, and are configured with sections between folds such that, in a fully compressed state of the container, the smaller diameter wrinkles fit into the larger diameter wrinkles. This wrinkle design achieves a more even distribution of the polymer material during container design and greater resistance to vertical forces. The container is of various forms of cross-section of the body, preferably circular. It is made of polyethylene or polypropylene, which allows storage of both the packaged product in refrigerators and freezers because they remain solid, resilient and flexible at freezing temperatures and at room temperatures. This is key to immediately stretching the container, diluting it with liquid, and consuming the contents of the container as soon as it is removed from the freezer. The application also describes the process of making a container by the process of casting plastic material by blowing.

EP patent application 611700, published August 24, 1994, describes containers for liquids comprising a flexible body of a container with a non-circular cross-section of a body constructed from a series of several folds horizontally aligned with the axis of the container and a rigid portion of the container at the opening above, where both parts are integrally formed. The key to this is the non-circular, preferably rectangular or octagonal, cross-section of the flexible body part of the container. Such a body shape allows the container to remain in the compressed state after it has been compressed, and after the fluid has been emptied, it will not be stretched back. This saves storage space for empty containers. The container is made by the process of injection of plastic material by blowing and is used for packaging liquids, preferably liquids for photo development.

Patent Application WO 88/02726, published Apr. 21, 1988, describes compressible hollow articles. containers of cylindrical body shape as n. BC plastic bottles or tubes with at least part of the side wall in the form of compressible folds, which have improved configuration and geometry of the folds. The so-called inner parts of the folds extending inwardly into the space of the container, unlike the outer parts of the folds extending outward, have a special shape with an additional angle in both arms of the folds, where such a shape allows the compressed state of the container to be folded the folds of the wrinkles are completely brought together and squeezed together. This achieves better compression and stability of the pleated portion of the container in a compressed state. Such geometry extends the use of high density linear plastic polymers for the manufacture of compressible containers by helping to reduce or prevent the formation of crystalline fractures and the weakening of the container wall by internal wrinkles at first compression together, while maintaining the wrinkling property and compression stability of the folded portion of the container. Improved wrinkle geometry for low density plastic, elastomer and rubber containers allows them to remain stable in the compressed state.

EP 850842, published 1.7.1998, describes a compressible container with a pleated side wall with a special geometry and configuration of wrinkle arms, which have specially shaped recesses at the outer tip of the folds and / or along the inner valley fold. This design allows better control of the compressibility of the container to retain the fully compressed or partially compressed form of the container.

Patent Application WO 2016/162868, published October 13, 2016, describes a compressible crucible for medical diagnostics, consisting of a pleated lateral wall of a series of circular folds in a horizontal direction relative to the vertical of the crucible, which are connected to each other by intermediate annular parts, from the base of the crucible and openings above. Such a crucible occupies a minimum volume in the compression phase of the folds. Preferably, in such a pot, the diameter of the crucible above the opening is larger than the diameter at and at the bottom of the crucible. Along the opening, the crucible is semi-conical in order to prevent the liquid from flowing up and out of the crucible and from spraying it and, if necessary, to fit the cap.

Patent Application WO 2017/052475, published 3/30/2017, describes a specially designed compressible bulk container consisting of a flexible intermediate portion extending between the lower portion and the upper portion of the container, wherein the flexible intermediate portion consists of a series of horizontal forming wrinkles an accordion-shaped pleated wall that allows the container to be stretched or compressed vertically by vertical force on the container. The described container also includes an inlet or inlet guide with an opening in the upper part of the container for filling the contents into the container which is closed by choice, and a drain or drainage guide with an opening in the lower part of the container which is opened by the choice for pouring the contents from the container .

Preferably the pleated portion of the sidewall of the container, which is horizontally disposed in this wall according to the vertical direction of the container according to the present invention, covers from 20% up to and including 80% of the surface of the sidewall of the container from the entire surface of the sidewall of the container in the fully extended state of the container. Even more preferably, the folded portion of the sidewall of the container according to the present invention overlaps from 30% to 70% inclusive of the surface of the sidewall of the container and most preferably from 40% up to and including 60% of the surface of the sidewall of the container from the entire surface of the sidewall of the container in a fully extended the condition of the container.

According to the present invention, the pleated portion of the sidewall is located or the pleated portions of the sidewall are located in any part of the sidewall along the vertical of the side wall or along the vertical of the container. In one embodiment of the present invention, the pleated portion of the side wall is located, or all the pleated portions of the lateral wall are located in the middle part of the vertical height of the container wall, in the other embodiment, one pleated portion of the side wall is located in the upper half and the other in the lower half of the vertical the height of the container wall and, in the third embodiment, one pleated portion of the side wall is located in the upper third, the other in the middle third and a third in the lower third of the vertical height of the container wall.

In one alternative embodiment of the invention, the pleated portion of the side wall is located, or all the pleated portions of the lateral wall are located in the upper third of the vertical height of the container wall. In another alternative embodiment, the pleated portion of the side wall is located, or all the pleated portions of the lateral wall are located in the middle third of the vertical height of the container wall. In a further alternative embodiment, the pleated portion of the side wall is located, or all the pleated portions of the lateral wall are located in the lower third of the vertical height of the container wall.

In a still further embodiment, a container having two or more folded portions, the folded portions, or folded portions of the side wall, are arranged with one another flat portions of the lateral wall so that one folded portions or several folded portions is located in the upper third of the vertical height of the wall and that the second pleated portion or other pleated portions are located in the middle third of the vertical height of the container wall. In a further embodiment, with two or more pleated portions, the pleated portions, or the pleated portions of the side wall, are arranged with one another flat portions of the lateral wall so that one pleated portions are located in the upper third of the vertical height of the container wall and the other pleated portions or other pleated portions in the middle third of the side wall of the vertical height of the container wall. Further, in the embodiment, with two or more pleated portions, the pleated portions or the pleated portions of the side wall are arranged with straight flat portions of the lateral wall so that one pleated portions are located in the upper third of the vertical height of the container wall and the other pleated portions or other pleated portions in the lower third of the side wall of the vertical height of the container wall.

Each flexibly folded portion of the side wall of the container according to the present invention consists of at least one or more folds. Such a crease has either a sharp-shaped tip and a sharp-formed angle upon contact with the plane of the side wall, thus having a cross-section in the form of a triangle. Either the wrinkle has a rounded tip and the rounded contact of the wrinkle with the plane of the side wall, and thus in cross-section has the shape of a half curve of a more or less sinusoidal curve or other similar curves with a rounded wave-like shape. An individual crease has the tip of a crease extending from the plane of the flat part of the side wall of the container, either outwards from the body of the container, forming the so-called outer crease, or inwardly into the body of the container, forming the so-called inner crease. When the flexibly folded portion of the side wall consists of only one crease, then its tip extends into the inner container of the present invention and forms an inner crease.

The crease of the present invention consists of the top of the crease formed by the connecting arms of the crease, and of the two creases of the crease, where the lower crease of the crease is closer to the bottom of the container and the upper crease of the crease is closer to the top of the crease. The folds of the wrinkles and the top of the wrinkles extend from the plane of the wall of the container either outwards from the container and form the so-called outwardly directed fold. the outer crease or the arms and the tip of the crease extend from the plane of the vessel wall inwards into the space of the vessel and form a so-called inwardly oriented crease, respectively. inner fold.

In order to minimize the volume of the container according to the invention in the compressible phase of the expandable container according to the invention, in the preferred embodiment, the top of the fold when there is one fold is located or the tops of all folds when there are more folds are below the plane of the side wall and / or at most in the plane of the side wall of the container and the top of any crease does not extend outward from the inner space of the container and thus outwards from the plane of the side wall of the container. In such embodiments of the invention, for example, Figures 1, 2, 4, 9 and 11, the packaging container has all the folds configured to be located inside the container space, i.e. inwards from the plane of the side wall of the container so that all wrinkles, that is, wrinkles with tips pointing to the inside of the container or. inner folds, and folds with the tips pointing outwards from the container or. outer folds located inside the container space. In the alternative embodiment shown in Figure 4, all the folds of the pleated portion of the lateral wall are folds with the tips directed toward the inside of the container, which is achieved by the configuration of folds with intermediate short straight sections of the lateral wall between successive folds. Such designs of pleated sidewall sections are intended to maximize space savings in the container during the packaging, storage, transport, distribution, delivery and sale phases.

A single crease, when sharpened by the edges and angles of the crease, as shown in Figures 1 and 2, forms an angle β along the top of the crease and thus between the crease arms and at the same time the angle between the crease arms and the plane of the side wall of the container, which are an angle a between the lower crease. folds and plane of the side wall of the container, t. j. the angle along the crease arm closer to the bottom of the container and the angle γ between the upper crease arm and the plane of the side wall of the container, t. j. as at the crease, which is closer to the top of the container. In a preferred embodiment of the invention, the angles a and γ are the same, and then the cross-section of each fold has the shape of an equilateral triangle. In the rounded design of the edges of the crease, the individual crease forms a rounded tip of the crease and approximately an angle in the range from about 0 °, preferably from about 45 °, to about 90 ° at the contact of the crease with the plane of the side wall of the vessel, depending on the compression of the creases. The angles indicated in both the design of sharp wrinkles and the rounded wrinkles depend on the compression of the wrinkles. The more the wrinkles are compressed side by side, the greater the angles a and γ, approaching the 90 ° angle, and the smaller the β angle, approaching the 0 ° angle, while compressing the greater part of the lateral wall in the form of folds, and thus depending on the proportion the folded part of the side wall of the container saves more container space in the compressed state.

The shape and dimensions of the container according to the invention may be arbitrary. For example, a container has a shape that has, at the bottom of the container, at the top of the container and in the body of the container from the bottom to the top of the container in horizontal cross-section with respect to the vertical of the container, a shape selected from a circle, an ellipse, a triangle, a square, a rectangle, a parallelogram , trapezoids, orthogonal shapes and / or any other more or less circularly rounded shapes or any other more or less angularly shaped shapes and / or simultaneous combinations of such circularly rounded shapes and such angularly shaped shapes.

The inlet nozzle is also a blower device, which includes a tube inside which leads to the nozzle nozzles, where air or other gas is blown out of the nozzle through the nozzle into the nozzle at elevated pressure and at an appropriate temperature so that the preform is reshaped and stretched all the way to the mold walls, thereby transforming it into the shape of the finished product of the container. This extends the preform of the polymer material to the volume and shape of the mold, including the wrinkled textured side wall. The packaging material of the present invention is formed from a polymeric material. This is followed by the step of cooling the container and then squeezing it together to the volume and shape of the side wall folds.

In an alternative embodiment, this packaging container manufacturing process involves the steps of melting a polymeric plastic material at temperatures above the glass transition temperature and at the same time below the melting temperature of the selected polymer, preferably in the form of granules or pellets, followed by pouring the polymer into a mold with a so-called precursor shape or. pre-formulation of the product, preferably a mini-crucible or test tube, and then such preform of the product with a nozzle is inserted into a pre-prepared mold with the texture of a side wall that is heated in the heating chamber and then subjected to high pressure and blowing. heated air or single gas to extend the polymeric material to the volume and shape of the mold having a textured side wall with folds, to form a packaging container of the present invention from the polymeric material, followed by cooling the container and compressing it together to a volume and shape compression of the side wall folds.

The packaging container of the present invention reduces the consumption of packaging / packaging material and the consumption of space and associated costs (e.g., energy, fuel, propulsion machinery and / or assets and infrastructure) during packaging, storage, transportation, the distribution, delivery and / or sale of the packaging container of the invention itself or such packaging container together with the product being packaged therein. Spend n. BC less packaging material and / or transport carton due to the significantly smaller volume of such products or packaging. goods and consequently reduce the cost of distribution of transport cartons, pallets, containers, etc. In addition, the compressibility of the wall of such a container also means a significantly smaller volume when recycling or destroying packaging waste, since such a container, a container, a pot or a container. bottle easier to squeeze and fold together after use. At the same time, such packaging is also practically useful for the end consumer, as the latter handles the container, the pot or the container. a small volume bottle which is stretched before the preparation of the product, and an ingredient other than n is added thereto. BC water or other liquid. At the same time, such packaging / container is cooler on the flexibly stretchable and compressible part, since the air between the pressed folds further insulates the wall of the container and also cools it if necessary. In addition, the folded or wrinkled part of the side wall of the container is less slidable due to such construction, which enables better holding of such container. In the case of packaging containers made of environmentally friendly materials, this will further reduce the amount of harmful waste.
