Abstract

  A carton such as the milk carton NL with the characteristic feature that it has a top part that is fully open and folded flat. This flat folded carton exhibits the same characteristic features as (FIGS. 54, 55, 56), and comprises the folds required to be unfolded and then refolded. These cartons are clean and unused and are packaged hygienically. They can be rinsed, washed and reused. A series of figures is provided on the outside of the carton, showing how the carton is unfolded and how it is subsequently closed and refolded.

Description

  The container P is formed of a flat rectangular bottom portion having four flat rectangular side portions and an opening having the same size as the bottom portion. A container commonly used in the Netherlands for 1/2, 1 or 1 and 1/2 liters of pasteurized milk pasteurized milk as a unit of capacity is referred to herein as "Milkcarton NL". P is formed of the same waterproof carton as the plastic coating forming the milk carton NL. Various dimensions, sides, bottoms, and openings of P may vary. P may have several combinations of folds prepared for use to fold the P flat (especially FIGS. 54, 55, 56), the prepared folds of milk carton NL It is used for the opening (spout) and the upper part. The upper part of P with the opening has a prepared fold, and by folding it together, it looks closed like the closed upper part of the milk carton NL. P is folded and sold as a bundle.

  The combination of prepared creases used for P folding and unfolding can be used in combination with existing packages filled by the manufacturer. This allows them to be more easily folded flat after being used and empty. This reduces the space occupied in the garbage or waiting for recycling (particularly, FIGS. 3, 5, 20, 37, 47, 49).

  A series of figures are located outside the package to illustrate how the package is folded. If the package is filled with custard, some of it may remain inside the package. The series of figures may explain how to squeeze out the last small amount of custard as the package is folded. Also, the series of figures are located outside P and explain how P is unfolded and how it can be folded flat again if desired.

  Once opened, many carton openings that do not have screw caps for liquid material will leak if shaken or held upside down. The upper part of the opening formed from several layers on the folded side of the closed opening of the milk carton NL is referred to as “A”. Leakage can be prevented by pressing several layers of the opening of the milk carton NL (A) strongly between each other. However, if A is not firmly pressed against each other when shaken or turned upside down, the liquid material will leak.

  The fasteners are made of metal or hard plastic that looks like a tube that is split from one end to the other, just like a rolled rectangle. If a fastener with a split is pressed around A and the pressure on both sides of the split is sufficiently high, the milk carton NL will be sealed in a waterproof state. The corners / angles and edges on both sides of the split are rounded to facilitate sliding the fastener around A. Both sides of the split pressed against A may be divided into two ledges with a small groove in between. As a result, the contact surface with A becomes smaller, the both side portions of the split are pressed deeper into A, and it is not necessary to use a larger force. Also, one side of the split is formed by two ledges and a groove between them, and the other side of the split is formed by a small ledge at its center, which fits into a wider groove in the center of one side You may make it do. In order to prevent the fastener from unexpectedly slipping off from A, a thick material may be bonded to the upper side of A (shaded part in FIG. 53). This thick material can be an extra layer of carton affixed to both sides of the upper side of A. Under this thickened portion, there is sufficient space to slide the fastener split about A. In order to make it easier to unfold and fold (open / close) the spout of the opening in the milk carton NL, the excess layer of the carton forming the thick material part may be interrupted around the intersection with the crease . Thereby, the pouring spout of the milk carton NL becomes firm, and it becomes easy even when the milk carton NL is opened for the first time. To prevent the fastener from accidentally sliding at A, four hooks may be attached to the fastener at the four corners / corners of the split. These four hooks are hooked around the four edges on the two inclined sides of the folded upper part of the milk carton NL and are arranged below the edges. If one of the hooks is placed below the edge of the inclined side at one end of A, the distance to the other pair of hooks will be as small as possible, and those points on the hook will be inclined. Sufficient space is provided to be pushed down on the edge of the side, making it difficult for the fastener to slip unexpectedly. The fastener may be formed from two parts that partially fit each other and have a pair of hooks at both ends of the split (FIG. 59). The twisting of the two parts can be prevented by several grooves provided in one part and several protrusions fitted in the grooves provided in the other part. By using a spring, the two parts are securely inserted into each other and held firmly together. The two sides of the fastener split can be pressed more firmly and integrally using bolts or internally threaded screws. These bolts and screws are arranged at right angles to A from one side of the fastener to the other side. To close A, the pressure on both sides of the split and the pressure applied to them are important. The tube shape of the connection between the two sides in the split may be different (FIG. 57 at the bottom right of the first page of the drawing).

  The fastener can close the folded opening of P by pressing several layers of the two folded spouts, so that the opening of P is firmly formed integrally. If the two spout points are well connected to each other and there is no space left between them when folded, the P opening will be sealed waterproof. If the opening of P is rectangular instead of square, the two points of the folded spout will not touch each other. An extra layer of cartons may be attached inside the two layers that form the outside of A to fill the space between them. In this case, A is formed by the same number of layers as a whole.

  The fastener may also be configured in a rectangular shape with a rigid carton with a slit that is crimped around A and closes A by pressing it together (FIGS. 1 and 8). Both ends of the rectangle may be bent downward and may be bound to the side portion of P using an adhesive layer as necessary. A layer of corrugated paper may be attached to the lower side of the carton's rectangular shaped piece on either side of the slit at right angles to the slit so that the heel opening faces A. When the rectangular piece of the carton is folded upward, the slit becomes part of the fold and is pushed down around A. When the end portion is flattened and folded downward, the opening of the corrugated cardboard paper is firmly pressed against both sides of A. The edge of the corrugated cardboard may be cut at an angle inclined with respect to A, and the pressure applied to the lower part of A may be maximized by the V shape. A further layer of cardboard may be affixed to the underside of the end of the carton rectangular piece. When this end is folded down, this additional layer will support the shape more firmly. This further layer is interrupted around the fold so that it does not interfere with the folding or unfolding function. This further layer may match the triangular space / cavity below the folded side of the upper side of P. The end part folded below the fastener may be bound to the side part of P using a kind of adhesive. The end folded down of the fastener may also be attached to the outer periphery of the body of the P / milk carton NL (FIG. 51). A liquid absorbing layer may be attached to the outer peripheral portion of the main body of the P / milk carton NL so as to catch droplets that spill on the side after pouring a portion of the contents. The outer periphery of the main body having a liquid absorbing layer for catching droplets of P / milk carton NL can be used without a fastener attached thereto. Further, a rectangular portion made of a material that absorbs liquid may be attached to the side portion of P with a tape. This tape is bound only on the right side, the left side, and the lower side, and the upper side is left in an open state so as to catch and hold the falling droplet. Alternatively, a cloth or fabric that absorbs liquid may be used in combination with a fastener such as an elastic ribbon or Velcro (trademark) to surround the P body. In this case, it can be washed together with other dirty laundry.

  The deployed waterproof P is filled or emptied with liquid material by the consumer himself, and after use they are cleaned and reused. P can be washed in a dishwasher.

  Alternatively, the groove O (FIG. 2) may be formed from the same material as P to collect liquid or other articles. O is a rectangle divided into three rectangles, with two folds between them. In P, if O is placed so that its edges enter the two corners of the fourth side, the three rectangles of O fit well with the three sides of P. Two depressions are formed at the edges of the two outer side portions of O. The recess is formed by two rectangular cuts. These depressions are hooked around the rim of the opening of P, support O, and stabilize the shape of O even when the upper part of the opening of P is gripped somewhat intensely. O helps P to capture and collect liquids and other items, and if the combination of O and P is tilted, the liquid or material will slide inside P. This combination of O and P can also be used by women to piss. Squat and hold between both legs and press against vagina. This combination of O and P can also be used to enter male urine, during which O can hide the genitals. After use, O is removed and pushed into P, after which P is closed. The corner / corner as the portion of O protruding from P may be bent, cut, rounded, or bent to fit the user's shape.

  A version of P with dimensions 40x40x60 cm can be used as an emergency toilet. If necessary, a plastic bag such as a trash bag may be disposed inside. If desired, a toilet seat with foldable legs may be placed thereon. The lower end portions of these legs may be connected to each other by a tubular or flat shape so that the toilet seat becomes more stable. In order to ventilate the inside of P, the upper side portion / opening portion of P may be folded without a fastener to press the plurality of layers firmly and integrally. In order to shield the folded upper part / opening of P from rain, create a vertically folded rectangle, also made of waterproof carton P, and use it as the roof (roof D) located above A (A is the folded upper / opening of P). One side of D is partially attached to one side of P, and the other side of D is locked to the opposite side of P. For example, a tab shaped like the tip of an arrow can be used. This tab can be hooked onto the side of P by pushing it under the rectangle connected to both ends of the side of P. If necessary, a fine mesh layer may be used to shield the folded upper / opening of P from insects. Once this version of P is full, it is desirable to empty it as soon as possible. A valve may be attached to the side of P to ensure that the pressure rising inside P does not exceed a certain level. A filter is incorporated in this valve to prevent the contents of P from coming out. Before and after the use of this version of P, you may put in it what sterilizes and thickens its contents.

  A rectangle formed by attaching two small rectangles constitutes a groove passing through the middle in the vertical direction. If two of these combinations of rectangles are hinged to each other and connected to both grooves on the outside, if necessary, two layers of rubber bound to the inside of the object A or a plastic bag may be bent around the opening of the plastic bag and pressed securely using a fastener that fits into the groove. When two combinations of rectangles are joined together so that their minimum sides are hinged, hooks are attached to one corner of the rectangle and the other corner of the rectangle. It is attached to the corner on the side with the rectangular hinge. The object can be formed from plastic, metal or carton.

  The fasteners can also be formed from two rigid rectangles that are hinged together and the two rigid rectangles are pressed together with screws.

  An adhesive layer may be provided inside the rim of the P opening. This adhesive layer may be covered with a removable foil piece.

  A further layer is applied to the upper side of A so that the fastener does not slip (in that direction), and this is the opening of the carton and the tip of the deployed flap at one corner of the carton is cut off. You may affix around the formed opening part (FIGS. 5, 15, and 20). In this case, the openings in these cartons will be tightly closed using fasteners. Between the corners of these cartons, a triangular flap exists so as to be unfoldable. An opening can be created by cutting off the tip of the deployed flap and pouring the contents. A further layer of carton affixed around the dotted line where the tip of the flap is cut off to create an opening prevents the fasteners pushed around the flap from accidentally slipping in that direction.
