Description

  The present invention relates to a edible oil delivery and a waste oil recovery case for delivering edible oil for business use such as frying tempura or for household use and allowing the waste oil to be conveniently recovered.

  In the past, edible oil traders have generally delivered them to customers such as food processors and restaurants that purchase them in metal containers such as cans. In this case, the waste container was filled with waste oil in the same container that had been opened to the customer, and the waste oil was collected, but it was difficult to dispose of the metal container that was contaminated with the waste oil. Therefore, recently, a recyclable corrugated cardboard case is used instead of a metal container, and edible oil is delivered in small plastic bags and pillow-wrapped, and the customer separately prepares waste oil as return cargo. I was allowed to take it in.

  However, when the corrugated cardboard case is used as described above, it is easy to clean the corrugated cardboard case after collecting the waste oil, but it is not easy to pack the waste oil because a separate separate container is used for return cargo. In addition, waste oil that has been used may be put into a plastic bag immediately after frying the tempura from the procedure of the work procedure. At that time, if the waste oil reaches about 180 ° C, the seal part of the bag is If it is stuffed after being left to stand until the temperature drops to avoid this danger, there is a problem that the procedure for frying the tempura is poor.

  In view of the above situation, the present invention uses a corrugated cardboard case that can be incinerated, and is delivered in pillow packaging, but it is not necessary to prepare a separate container as a return package, and in the attached bag An object of the present invention is to provide a edible oil delivery and waste oil recovery case that can be conveniently packed with waste oil and can withstand it even at a high temperature of about 180 ° C.

  In order to solve the above-mentioned problems, the first invention is a edible oil delivery and waste oil recovery case for transporting pillow packaging oil into which edible oil is subdivided, and a spout with a cap for injecting and pouring the waste oil is provided at the top. It consists of a cardboard outer box as the case body and a resin inner bag filled with return oil from the spout. The outer box has a spout attached to a flap that is connected to one face wall. The bag is sealed by sealing both ends of the tube of the resin film, and is attached so as to be in contact with the wall at the rising base so that it bends in an L shape between the seals at both ends, and the pillow packaging oil is placed thereon. An edible oil delivery and waste oil recovery case is provided which is laid on the bottom of the box (claim 1).

  The second invention is a edible oil delivery and waste oil recovery case for transporting pillow wrapping oil divided into edible oils, and a corrugated outer box as a case body provided with a spout with a cap for injecting and pouring the waste oil into the upper part And a plastic inner bag filled with return oil from the spout. The outer box has a spout attached to a flap connected to one face wall, and the inner bag is attached to both ends of the resin film tube. Sealed and sealed, inverted between the seal parts at both ends, the tip part is folded back to the base part, and the base part is attached by attaching to the one surface wall, while the inverted tip part is adhered to the base part or the face wall by the seal part In addition, an edible oil delivery case and a waste oil recovery case are provided in which the height is given to the end seal portion of the tip portion by folding back (claim 2).

  A third invention is a edible oil delivery and waste oil recovery case for transporting pillow packaging oil into which edible oil is subdivided, and a corrugated outer box as a case body provided with a spout with a cap for injecting and pouring the waste oil into the upper part And a plastic inner bag filled with return oil from the spout. The outer box has a spout attached to a flap connected to one face wall, and the inner bag is attached to both ends of the resin film tube. The inner bag is placed sideways along the wall, and the base is bonded to the wall so that the seals at both ends are on both sides. The edible oil delivery and the waste oil recovery case are characterized by being bent into a shape and arranging both the seal portions of the triangular width portions upward so that the heights of both the seal portions are given. Term ).

  A fourth invention is a edible oil delivery case for transporting pillow packaging oil into which cooking oil is divided and a waste oil recovery case, and an outer box made of cardboard as a case body provided with a spout with a cap for injecting and pouring the waste oil into the upper part And a plastic inner bag filled with return oil from the spout. The outer box has a spout attached to a flap connected to one face wall, and each inner bag is made of a resin film tube. A double bag consisting of an inner short bag and an outer long bag sealed at both ends, with a common seal on both bags at the upper end, and a spout at the upper end connected so that waste oil can be injected into the inner short bag The long part of the outer long bag is folded back to the back side at the position of the lower end seal part of the inner short bag, and the folded part of the face wall is raised along the face wall and the rising part is bonded to the face wall. , There is provided a collection case of delivery and the waste edible oil, wherein the seal portion of the outer length bags are held in face wall (claim 4).

  The edible oil delivery and waste oil recovery case Pa in this invention is a cardboard outer box 1 and an attached inner bag 2 that is always built in it. The outer box 1 is made of recyclable paper cardboard or resin cardboard. Thus, the cardboard structure is not particularly limited, and the box type is in principle the A type.

  The inner bag 2 is a prototype of a sealed flat bag in which seal portions 33, 34, 36, 37, and 38 are formed on both ends of a resin tube film, and a resin serving as a pouring inlet on the back surface of one end thereof. Although the spout 6 with the cap 20 made of is attached, there are a vertical usage method (Claims 1, 2, and 4) and a horizontal usage method (Claim 3) depending on the arrangement of the seal portion. There are also various materials for the resin film of the inner bag 2.

  Moreover, in order to ensure safety, it may be configured as a double bag comprising an inner short bag 10 filled with the contents and an outer long bag 11 covering it (Claim 4). In this case, Although the inner short bag 10 is filled with liquid from the spout 6, it is desirable that the seal portion 38 of the outer long bag 11 is held at a certain height H so that liquid such as waste oil does not reach.

  The inner short bag 10 of the inner bag 9 is not particularly limited as long as it is a heat resistant film, but the inner short bag 10 is a laminate of polyethylene (outer layer) and nylon (inner layer), and the outer long bag 11 is A laminate film of nylon (outer layer) and polyethylene (inner layer) is particularly preferable.

  The form of the bag is not particularly limited, such as a flat bag or a gusset bag, but a flat bag is particularly preferred because it is difficult to seal nylon gusset.

  As for the folding type, the transformation in the rhombus direction is possible as the A formula, but the deformation in the flat direction by the pair of left and right middle folding lines 50 and 50 (see FIG. 12) is also possible.

  In the outer box 1, the left and right side walls 19 and 19 and the front and rear side walls 21 and 21 are alternately arranged with respect to the body as the A type, and the inner flaps 23 and 23 are provided on the upper and lower ends of the side walls 19 and 19, respectively. Outer flaps 25 and 25 are connected to both upper and lower ends of 21 and 21, respectively, and are assembled into a rectangle with a margin at one end. Among them, a hole is provided in the outer flap 25 on the front side, and the spout 6 is fitted thereto.

  The inner bag 2 is basically a sealed flat bag with heat seals 33 and 34 at both ends of the tube film, and a spout 6 is attached to the back of one end of the tube. It is fitted to the flap 25. Accordingly, the left and right inner flaps 23, 23 are provided with corner notches 31, 31 so as not to obstruct the attachment of the inner bag 2 together with the spout to the outer flap 25.

  FIG. 1 shows a form in which an inner bag 2 is combined with an outer box 1. The inner bag 2 is folded into an L-shape as shown in the figure as a flat bag, and the upper half 2 a is a front wall 21. The lower half 2b is laid face down on the bottom surface in a non-bonded state. Accordingly, the pillow packaging oil 5 is placed on the lower half 2b and boxed.

  FIG. 2 shows the appearance of the packaging state of the pillow packaging oil 5 (see FIG. 4) (the same is the appearance of the waste oil in the packaging state (see FIG. 5)), and the outer flap 25 is placed on the inner flaps 23, 23. 25, the lid is closed, but the attachment part of the spout 6 and the inner bag 2 is housed in the space between the notches 31, 31 of the inner flaps 23, 23.

  The procedure for use by the user when edible oil is delivered is to open the lid, take out the pillow packaging oil 5 and use it, inject the waste oil from the spout 6 into the inner bag 2 with the lid closed, When the appropriate amount is reached, the spout 6 is tightened with the cap 20 and the merchant takes it.

  FIG. 6 shows an embodiment of the second invention, and the edible oil delivery and the waste oil recovery case Pb is substantially the same as in the previous embodiment, but the inner bag 3 has a base end 3a. Is attached along the face wall 21, but the distal end portion 3 b is bent so that the seal portion 34 is positioned upward, and is bonded to the base end portion 3 a at the position of the seal portion 33 at the height H. I'm allowed.

  In this way of attaching the inner bag 3, the seal part 33 at the upper end of the base end part 3a is in the highest position close to the outer flap 25, but the seal part 34 at the tip is also in the highest position near it, When injected, since it does not reach the seal portions 33 and 34 at the inverted folding height H, the seal portions 33 and 34 are never damaged by the high heat of the waste oil.

  7 and 8 show an embodiment of the third invention, and the edible oil delivery and the waste oil recovery case Pc used the inner bag 4 so that the seal portions 35 and 35 are vertical. The base portion 4a is bonded to the face wall 25, but the left and right corners are bent into a triangular width so that the seal portions 35a and 35a of the triangular width portion 32 at the distal end are outside at positions where the height H is reached so that the waste oil does not reach. Bonded to the box 1.

  In the case of the first embodiment, the seal portion 34 at one end is positioned below, but since the path through which the waste oil reaches it is long, cooling can be expected between them, so that the heat loss of the seal portion 34 can be prevented. In the case of Examples 2 and 3, the capacity of the inner bags 3 and 4 tends to decrease, but the edible oil becomes waste oil reduced by use, so there is no problem with the capacity.

  FIGS. 10 to 14 show an embodiment of the fourth invention. The edible oil delivery and the waste oil recovery case Pd is placed in the outer bag 1 in the same manner as in the above embodiments. 9 is attached to the upper end portion of the outer box 1 and exposed to the outer surface thereof.

  The outer box 1 has an A-type arrangement of left and right side walls 19, 19 and front and rear side walls 21, 21, and inner flaps 23, 23 at the upper and lower ends of both side walls 19, 19, Outer flaps 25, 25 are respectively provided at both ends, and a mouth hole is provided in the outer flap 25 at the upper end of the front surface wall 21, and the spout 6 with the inner bag 9 is fitted into the mouth hole. However, there are differences as follows.

  The inner bag 9 is composed of an inner short bag 10 filled with waste oil from the spout 6 and an outer long bag 11 containing the inner bag. Both the bags 10 and 11 are long and short, but the back side of the outer flap 25. The common seal portion 36 is welded together at the upper end corresponding to the position. The spout 6 is connected near the common seal portion 36. About this, a connection hole is provided in each, and the peripheral part of the connection hole is adhere | attached on the inner periphery of the spout 6 and the outer flap 25 at the hole periphery. Therefore, the lengths of both bags 10 and 11 occur at the lower end.

  The inner short bag 10 extends from the common seal portion 36 at the upper end along the inner surface of the outer box 1 so as to lie down on the bottom portion, and the lower end seal portion 37 is located on the bottom portion. On the other hand, the outer bag 11 having a long dimension is folded inward at the position of the lower end seal portion 37, the folded portion 40 reaches the surface wall 21 along the bottom portion, and rises along the surface wall 21. The rising portion 40a is partially bonded to the face wall 21 (FIG. 12). As a result, the upper end seal portion 38 of the outer elongate bag 11 is given a height H at the position of the back surface of the flap, that is, the position of the upper end of the face wall 21. The height H is held by the partial adhesion 39.

  The expansion of the lower end portion of the inner short bag 10 can be an expansion extending so as to crawl the bottom surface of the outer box 1, for example, can be ½ of the bottom surface width of the outer box 1, or the bottom surface The inner short bag 10 extending to the full width may be used.

  In the above, when the width of the lower end portion is about ½ of the bottom surface of the outer box, the inner bag is stored in the outer box when the outer box is folded, so that the inner bag is hardly damaged. However, the amount of contents such as liquid is small, and in particular, it may be shifted to one side and become unstable.

  On the other hand, in the case of the short bag 10 having the full width of the bottom surface of the outer box, when the outer box is folded, a portion where the short bag 10 protrudes from the outer box is generated, and the protruding portion is damaged or troublesome. However, in this case, not only the capacity of the contents is increased, but the contents are stored evenly, so that the contents are stable even when carried.

(Characteristics of the collection case Pd according to the fourth embodiment)
1. Rather than folding both the inner short bag 10 and the outer long bag 11 (complete folding), the inner short bag 10 can be shorter by using the above-described configuration, so that the cost can be reduced accordingly.
2. Since the film is less than the complete folding, the inner short bag 10 is likely to spread by the contents (see FIG. 11).
3. Compared with the case where both the inner short bag 10 and the outer long bag 11 are short, the outer long bag 11 bends and rises, so even if there is a seal leak of the inner short bag 10, the upper end seal portion of the outer long bag 11 Since 38 is at the upper height H, as long as it is used normally, no leakage by the seal will occur and it is safe.
