Description

  The present invention relates to a edible oil delivery and waste oil recovery case that delivers edible oil for business use such as frying tempura or for household use, and the waste oil can 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 customer filled the waste container with waste oil and picked up the waste oil, but it was difficult to dispose of the metal container dirty with the waste oil. Therefore, recently, instead of metal containers, we used cardboard cases that are easy to dispose of by incineration, etc., and delivered edible oil that was divided into plastic bags and packaged in pillows, and customers separately supplied waste oil as return goods. It was packed in the same cardboard case in a prepared plastic bag.

  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 plastic bag 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 circumstances, 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 bag as a return package, and waste oil is contained in the attached bag. It is an object of the present invention to provide an edible oil delivery and waste oil recovery case that can be conveniently packed and can withstand high temperatures of about 180 ° C.

In order to solve the above-mentioned problems, the present invention provides a edible oil delivery / waste oil recovery case for transporting pillow packaging oil into which edible oil is subdivided, wherein 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 main body and a resin inner bag filled with waste oil returned from the spout. The inner bag is a sealed flat bag made by sealing both ends of the resin film tube. The inner bag is formed into a double structure in which the inner tube film and the outer tube film are fitted and overlapped and integrated with the seal portions at both ends , and the inner and outer tube films are joined to each other. The spout is formed on a laminate film of the same material as the spout and the other side is a heat-resistant resin. To attach this spout to the connection hole formed in the inner bag and opened in the inner bag, the spout is sandwiched between the inner and outer tube films of the same material side as the spout and fused or bonded. The spout protrudes and is connected to the upper surface of the flat mold near one end of the inner bag, and lays in an insole so as to receive pillow wrapping oil on the bottom of the outer box, and both ends are disposed along both front and rear walls. The outer box is built up and installed, and a spout is fitted into the opening in the upper part of the outer box so that the seals at both ends of the inner bag are always held at the upper end of the outer box when injecting waste oil from the spout. The inner bag is bonded to both front and rear walls, and the inner bag is filled with waste oil by filling the outer bag below the seal portion while maintaining the rising of the seal portion. Edible oil To provide a collection case of Itaruken waste oil.

  The edible oil delivery / waste oil recovery case is configured as described above. When using this for delivery, pillow packaging oil is wrapped on the inner bag of the outer box with the lid closed, and returned to the home. When using, inject waste oil from the spout with the lid closed. At this time, if the waste oil is stopped before reaching the top of the outer box and injected, the seals at both ends of the inner bag rise and the seals are located at the top of the outer box, so that the waste oil reaches the high seal part. There is no. Therefore, although this is a principle of use, even if it is accidentally filled near the full tank, the waste oil does not become a high pressure that causes damage to the seal portion. In the present application, the side where the spout is connected to the flap is defined as the front side wall.

As described above, according to the edible oil delivery and waste oil recovery case of the present invention, it is delivered in pillow packaging using a corrugated cardboard case that can be incinerated. Of course, a safe transportation form can be obtained, and the waste oil as a return can be poured into the attached inner bag and packed conveniently. Even if it is injected at a high temperature of about 180 ° C, Since the seal portion does not reach the high place, the seal portion is not damaged by high temperature, and there is an excellent effect that the waste oil can be filled and transported extremely safely. In addition, the adhesive strength between the inner bag and the spout can be obtained by adhering the base bag of the inner bag in the same resin as the molding resin of the spout. Has been made heat-resistant by fusing heat-resistant nylon, etc., and has improved safety such as liquid leakage. In addition, it has the following effects.

(1) Along with the conventional transportation of edible oil, the cardboard outer box is an integral structure with the inner bag that can also be used as a waste oil container, and the inner bag is integrated. Injuries such as burns that occur when the bag comes off can be prevented, and the trouble of setting the bag in the cardboard box can be saved.
(2) It is convenient to provide a middle fold line on the width surface of the corrugated cardboard outer box (Claim 2), and to cut out the corner portion of the inner flap without causing an obstacle when putting waste oil from the spout.
(3) Since the inner bag has a sufficient width (Claim 3), it is possible to insert an appropriate capacity.

  The edible oil delivery / waste oil recovery case P in the present invention comprises a corrugated outer box 1 and an attached inner bag 3 that is always installed therein, and the inner bag 3 serves as a cushion for the pillow packaging oil 5. The return is a container for the waste oil 7 injected from the spout 6, but has been developed into a clever structure that will not be damaged by the high heat of the waste oil.

  The outer box 1 is made of paper corrugated cardboard or resin corrugated cardboard that can be disposed of by incineration, and the corrugated cardboard structure is not particularly limited. In addition to single-layer corrugated cardboard, two-layer corrugated cardboard is mainly used. Is desirable. As for the box type, in principle, the formula A is used, and a similar structure is desirable particularly for the convenience of taking in and out the pillow packaging oil 5 (see FIG. 3).

  The inner bag 3 is a prototype of a sealed flat bag in which seal portions 33 and 34 are formed at both ends of a resin tube film, and a resin spout 6 as a pouring inlet is attached to the upper surface of the one end portion. The connection hole 13 is opened. Since both the seal portions 33 and 34 are raised up together with the spout 6 of the connection hole 13 and are arranged at the upper end portion, the important portions can endure safely without touching high-temperature waste oil.

  As for the flat bag width W of the inner bag 3, the inner width of the outer box 1 on the left and right sides, that is, double-sided walls, in order to make it fit all the way into the lower half of the outer box 1 when bulging with the pressure of the waste oil 7 It is formed slightly wider so that more α and α are generated on the left and right than the width of 21 and 21, respectively. However, since the seal portions 33 and 34 are immersed in the outer box 1 so as to bump up to the top, the size of the width W is also constrained to be a common sense inner periphery. That is, when the waste oil 7 is added, the inner circumference when the bulge is generated so that a vacant space 15 (FIG. 5) is generated in the upper portion is set.

The inner bag 3 has a double structure composed of inner and outer tube films 35 and 36 in order to ensure strength and safety . To ensure the strength safety as a further measure, for each of the tube films 35 and 36, a different laminated structures resin material. Moreover, by doing in this way, besides ensuring the intensity | strength with respect to high heat, it can be made easy to adhere | attach to it according to the material of the molding resin of the spout 6. FIG. In this respect, safety can be ensured.

  As for the material of the resin film of the inner bag 3, nylon, a laminate film of nylon and polyethylene, polyethylene terephthalate (PET), a laminate film containing aluminum foil, a composite film or a functional film thereof can be suitably used. There is no particular limitation. In the experiment, a laminate film of nylon and polyethylene or nylon and polypropylene was particularly preferred. Nylon is easy to withstand high heat, and 6 nylon is particularly preferable because it is inexpensive.

The spout 6 is not particularly limited as long as the spout 6a is fixed to the outer box 1 and can be sealed with the cap 20. However, as shown in the following embodiment, the spout 6 has a high heat connection. It can correspond to.

Although the drawings show one embodiment, there is a portion schematically shown because the film structure of the inner bag 3 is not particularly finely illustrated. That is, in this case P, the inner bag 3 having a double structure is housed in the outer box 1 of the A-type cardboard box (FIGS. 6 and 7). In FIG. 5, only a single layer is shown, and in detail, the laminate structure is illustrated in an enlarged manner in FIG .

  As for the outer case 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 upper and lower ends of 21 and 21, respectively, and assembled by a glue margin 27 at one end. A mouth hole 29 for fitting the spout 6 is provided in the outer flap 25 on the front side. The film of the inner bag 3 is stuck to the outer flap 25 together with the spout 6 from this position. Therefore, the left and right inner flaps 23 and 23 are provided with notches 31 and 31 so as not to obstruct the outer flap 25 when the outer flap 25 is closed. In addition, in the assembly of the outer box 1 in the packaged state, an adhesive tape is stretched at a key point, but this illustration is omitted. Moreover, although the trunk | drum wall of the outer case 1 is a side wall, for convenience of explanation, the left and right side walls 19 and 19 and the front and rear side walls 21 and 21 are separated.

The inner bag 3, since it is basically a closed form at both ends flattened by the sealing portions 33 and 34 provided in the heat welded to the flat bag tube films, a high degree of securing the heat resistance in the present invention, the inner and outer While the tube films 35 and 36 are double, both the tube films 35 and 36 have a laminate structure made of two resins of different materials. Then, the base rod 37 of the spout 6 was sandwiched between the laminated films of the inner and outer tube films 35 and 36 at the rim of the connection hole 13 and welded thereto. Specifically, FIG. 7 will be described as follows.

  Of the inner and outer tube films 35 and 36 constituting the inner bag 3, the inner tube film 35 is made of a nylon resin having an excellent heat resistance property because the waste oil is directly touched, and the outer member 35 b is a polyethylene resin. Configured as On the other hand, the outer tube film 36 has an outer material 36a made of nylon resin and an inner material 36b made of polyethylene resin. That is, the polyethylene resin is detachably joined between the inner and outer tube films 35 and 36.

  The seal portions 33 and 34 of the inner bag 3 are formed in a two-stage arrangement of end seal portions 33a and 34a and inner seal portions 33b and 34b (FIG. 6) to prevent waste oil leakage in two steps. Measures are taken. Further, with respect to the flat bag width W of the inner bag 3, there are excess α and α on both sides of the front and rear side walls 21 and 21, and two folds 40 and 40 are formed at a wide interval at the center of the width W. It is easy to deform in conformity with 1 fold (by the middle fold lines 43, 43).

  The spout 6 is formed of a polyethylene resin and mainly includes a short tube opening 6a. In this embodiment, the spout 6 is provided with a tube opening 6a at the center of the mouth plate 39, and the base portion is extended to the bottom of the mouth plate 39. 37 is projected. Further, a short edge collar 42 projects from the upper end of the mouth plate 39, and the edge collar 42 is fitted into the mouth hole 29 of the outer box 1 from the inside. A large number of kerfs are formed radially around the hole 29 for easy passage (see FIG. 1). The cap 20 is structured to be tightly fitted to the upper end of the tube opening 6a.

  For the attachment of the spout 6, the connection hole 13 through which the mouth plate 39 passes is opened on the upper surface of the inner bag 3. In this case, the polyethylene (35b, 36b) of the inner and outer tube films 35, 36 is made to the polyethylene resin of the spout 6. Since it is integrated in the same resin material, a strong bonding relationship is born, and because it is coated with nylon (35a, 36a) with excellent heat resistance, it has heat resistance and impact strength strength combined with the double bag structure. As a result, it was possible to ensure a high level of safety and reliability.

  FIG. 1 shows how to combine the outer box 1 and the inner bag 3. The inner bag 3 is folded into a U-shape as shown in the figure as a flat bag, and is put in the outer box 1 and bonded to the double-side walls 21 and 21. . At this time, since the remainders α and α are bent along the side walls 19, 19, the inner bag 3 becomes a cushion surrounding the pillow packaging oil 5 (FIG. 3). One end 3 a may be bonded to the start-up (see FIG. 4), or may be folded over the pillow packaging oil 5. The left and right side walls 19, 19 are provided with center fold lines 43, 43 extending along the center of the width across the upper and lower inner flaps 23, 23. It is possible to fold the mated folds to match.

  FIG. 2 shows the appearance of the packaging state of the pillow packaging oil 5 (FIG. 4) or the packaging state of the waste oil 7 (FIG. 5). The outer flaps 25, 25 are overlapped on the inner flaps 23, 23, and the lid Is closed, but the spout 6 falls into the notches 31 and 31 of the inner flaps 23 and 23.

  FIG. 5 shows the packaging state of the waste oil 7. In the central portion between the double-side walls 21, 21, an empty space 15 is created by putting the waste oil 7 at a midway height. In this way, the start-up of the seal portions 33 and 34 is maintained in relation to the liquid level of the waste oil 7. In order to suppress the amplification of the wave motion of the waste oil 7, the bulging inner diameter of the inner bag 3 is set to about half of the inner circumference of the outer box 1. This is desirable from the viewpoint of securing the stability of the position of the waste oil 7 (see FIG. 8, claim 4).
