Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edible oil supply and packaging method for efficiently transporting and supplying edible oil to other places, and an edible oil accumulation package for the same.

[0002]

2. Description of the Related Art In recent years, consumption of edible oil used for processing foodstuffs has been increasing along with improvement of eating habits and westernization. At the same time, the flow rate of goods is increasing, and it is important to carry out transportation and supply to the consuming area by trucks and the like as efficiently as possible. By the way, food oil is manufactured from a raw material through a selection process, an extraction process, and a refining process.

[0003] Briefly, this process is firstly carried out by removing raw materials such as cereals and stones from the raw materials, and then being selected (a selection process). Thereafter, pressing is performed as a pretreatment. Further, the pressed raw material is put into an extraction container, a solvent is added thereto, and the fat and oil in the raw material is transferred to the solvent, and is separated into a volatile solvent and a fat and oil part by a distillation apparatus and extracted as crude oil (extraction step). The extracted crude oil is refined to remove impurities (refining step).

[0004] In the case of edible oil for business use, it is supplied to a filling machine, filled in a metal container 300 called a 1-to can, and packed by tightening a metal lid. This metal container 300
Is transported from a storage facility provided in an edible oil manufacturing facility to a storage facility such as a warehouse, a distribution center, or a wholesaler by using a transport means such as a truck. Thereafter, the food is transferred from the storage facility to a consumer, such as a food manufacturing factory, a cafeteria, a restaurant, or the like, by a transport means such as a truck.

On the other hand, if the food oil is household food oil, it is supplied to a filling machine and is a standing pouch which is a glass bottle, a plastic bottle, or a plastic container whose bottom can be widely raised (“Packaging Technology” published by Japan Packaging Technology Association 1999).
November 16th, pp. 16-947). Then, these are transported from the storage facility to a distribution center or a wholesaler using a transportation means such as a truck.
After that, the goods are transported to each store such as a supermarket or a food retailer, which is a consumer, by using a transportation means such as a truck.

[0006]

However, the above-described food oil supply system has the following problems. First, since it is difficult to completely remove the contents of a glass bottle, a plastic bottle, a metal can, or a standing pouch, oil (residual oil) adheres to the inner surface (for example, about 50 g per can). However, residual oil loss is inevitable. In particular, in the case of a metal can, it requires skill in opening and, after opening, a sharp edge is inevitably left, which may cause an accident such as an injury.

Further, the used glass bottles, plastic bottles, metal cans, or standing pouches need to be stored until they are discarded. However, since they are bulky, particularly in the case of business use, they are used in a wide storage space (backyard). Needs to be secured. In addition, legal regulations are becoming stricter every year for the treatment of waste cans for collecting the waste, and the number of disposal companies is decreasing recently.

[0008] In particular, when a stand pouch is used, it is convenient for ordinary household consumers because of its relatively small capacity. However, a special filling device having a rotary table (a so-called horizontal rotary table type feeder) is used on the supply side. (The bag filling and packaging line) is required, so that there is a disadvantage that the installation area of the filling process is large. In addition, a partition plate for preventing a fall during transportation is required, which is also inconvenient.

[0009] Further, when these glass bottles, plastic bottles, metal cans, or standing pouches are loaded and stored in container containers, gaps are formed between them, resulting in poor transport efficiency. In particular, at the time of recent high-speed transportation, the gaps collide with each other due to the gaps, so that deformation is likely to occur, and extreme damage may occur.

In addition, in the cooking oil filling step, it is necessary to prepare an empty container in advance for each container,
Therefore, a storage place must always be secured. As described above, in the conventional supply system, in the process from the saving facility (saving place) to the consumption place, the supply system is not always satisfactory in terms of the safety and efficiency of transportation (transfer) or work. Absent. That is, an object of the present invention is to provide a supply and packaging method capable of efficiently and safely supplying and transporting edible oil from one point to another point.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, in the supply and packaging method of the present invention, a filling step for filling edible oil into a plastic flexible bag at a storage location and loading the plastic flexible bag on an outer container are carried out. A first opening step for opening the outer container and taking out the plastic flexible bag, and opening the plastic flexible bag to remove the edible oil at the other consuming place. Second to take out
An opening step is provided, wherein the edible oil is transferred from the storage place to the consumption place and consumed, but here, first,
The pre-process for transporting and supplying edible oil to the storage location will be described.

First, in a manufacturing facility, raw materials are selected by removing foreign substances such as cereals and stones by various sorters (selection process). In addition, soybeans, soybeans,
Oil and cereal grains such as corn and sunflower are transported from each country by cereal vessels and stored in raw material silos. Then, crushing is performed as a pretreatment for extraction in order to crush and heat the raw material to make it easy to extract oil. When the pressed raw material is put into the extraction container and the solvent is added, the fats and oils in the raw material are transferred to the solvent.

This operation is continuously performed, and the oil or fat solution is separated into a volatile solvent and an oil or fat portion by a distillation apparatus to extract crude oil (extraction step). The extracted crude oil contains impurities such as proteins, gums, fatty acids, pigments, and fine contaminants, and purification is performed to remove these impurities (refining step). Thereafter, the refined edible oil is used as a product by mixing two or more kinds as necessary. Here, the edible vegetable oils that have become products include edible safflower oil, soybean oil, sunflower oil, niger oil, corn oil, cottonseed oil, sesame oil, rapeseed oil, rice oil, garlic oil, peanut oil, olive oil, palm oil, It is called palm olein, palm stearin, palm kernel oil, and coconut oil.

As described above, the edible oil produced through the respective steps of selection, extraction, and refining is transferred from the manufacturing facility 1 to a storage place (storage facility) using a mass transportation means such as a tank lorry. The cooking oil transferred to the storage location P1 is stored in a storage tank 11 (for example, a capacity 10).
５０50 tons). In this storage place P1, a step of filling the plastic flexible bag with edible oil and a storing step of loading and storing the plastic flexible bag in the outer container are performed. This will be described below.

A) A filling step of filling edible oil into a plastic flexible bag (see "Vertical bag making simultaneous filling and packaging line" shown in FIG. 2). The cooking oil stored in the storage tank 11 is
First, it is supplied to the filling loader 12. On the other hand, the plastic film 1 serving as a starting point of the plastic flexible bag 2 for packaging is prepared as a winding roll 14.

The strip-shaped plastic film 1 supplied from the winding roll 14 is filled with the filling loader 12.
Is formed into a cylindrical shape via a former 15 which is a shaping cylinder surrounding the periphery of the object, and is successively moved sequentially from above to below. At the same time, in the process of moving the cylindrical plastic film 1, the vertical overlapping portion Y of the plastic film 1 is heat-sealed by a vertical seal heater incorporated in the vertical sealing machine 16 to form a continuous hollow plastic film. 1 is molded. The hollow plastic film 1 has a feed roll 17 for feeding it downward.
Sent by

Next, the edible oil F supplied from the filling loader 12 fills the hollow plastic film with the pair of handling rolls 18 disposed below the feed roll 17 closing the lower end of the hollow plastic film. Is done. Hollow plastic film 1 filled with edible oil
At the lower end, the portion closed by handling the cooking oil is sealed by a pair of horizontal sealing machines 19.

That is, the lower end of the upper hollow plastic film 1 is heat-sealed to obtain a horizontal seal portion X, and the upper end of the lower hollow plastic film 1 is heat-sealed to obtain the upper horizontal seal portion X. . Thus, the continuous hollow plastic film 1 is
It moves downward sequentially and is cut off independently by a pair of horizontal seals and cutters 20. That is, the horizontal sealing portion X at the lower end of the hollow plastic film 1 connected upward is heat-sealed again, and the hollow plastic film connected continuously downward is separated and cut into a flat rectangular shape filled with edible oil. The plastic flexible bag 2 is obtained. As described above, the flat rectangular flexible plastic bag 2 which is an individual packaging form of the edible oil is formed.

B) Step of loading plastic flexible bags in an outer container and storing them (see FIG. 3) The plastic flexible bags 2 filled with edible oil as described above are transferred, for example, by a conveyor 21 or the like, and sequentially. The outer container 3 is housed in the outer container 3 (note that the already used outer container is used).

At the time of storage, the plastic flexible bag of edible oil can be placed horizontally so that the vertical seal portion is at a substantially horizontal position without using a partition plate for the outer container 3. The horizontal plastic flexible bags are stacked and stacked in a plurality of stages upward, and are similarly arranged in the horizontal direction. As described above, since the flat rectangular plastic flexible bag can be placed horizontally, the edible oil in the horizontally placed plastic flexible bag can be removed from the gap between the plastic flexible bags and the outer container. It acts to evenly fill the gap. For this reason, it is possible to load and store a uniform plastic flexible bag with extremely small voids as an integrated package. In particular, the viscosity range of the edible oil [eg, viscosity;
50 to 75 cs (centistoke), 25 ° C.], the above effect is very remarkable.

Therefore, when transported to another place by a truck or the like in a state of being loaded and stored in the outer container, collision of the plastic flexible bags can be avoided and a stable package can be maintained. The outer container 3 in which the plastic flexible bag 2 is loaded and stored as described above is transported from the storage location P1 to a consumption place P2 which is a store such as a food manufacturing factory, a cafeteria, a restaurant, a hotel, or the like by using a transportation means such as a truck. Be transported. However, it may be transported from the storage location P1 to the above-mentioned consumption locations P2 via an intermediate store such as a distribution center or a wholesaler. In this consumption place P2, a first opening step for opening the outer container 3 to take out the plastic flexible bag 2 and a second opening step for opening the plastic flexible bag 2 and taking out the edible oil are performed.

This will be briefly described below. C) First opening step of opening the outer container and taking out the plastic flexible bag (see FIG. 4). The outer container 3 transported to the consumption place P2 is opened with the lid 33, and the plastic flexible bag 2 stored therein is taken out. When the plastic flexible bag 2 is grasped by hand at the time of the removal, the filling pressure is evenly transmitted to the entire periphery of the bag, so that any part around the plastic flexible bag 2 can be grasped to obtain the same gripping force.

D) Second Opening Step of Opening Plastic Flexible Bag and Removing Edible Oil (See FIG. 5) The removed plastic flexible bag 2 is opened and the edible oil is discharged to a tray or the like. The opening here is performed by cutting a corner portion including the horizontal seal portion to form an opening 3A. As described above, since a certain amount of edible oil is completely discharged from the plastic flexible bag 2 in batches each time, the remaining amount of edible oil is reduced as in a conventional glass bottle, plastic bottle, or metal can. Missing the expiration date is avoided as much as possible.

After the edible oil has been discharged from the plastic flexible bag 2, the plastic flexible bag itself has almost no volume and becomes a single sheet and is not bulky, so that collection and disposal are extremely easy. Further, at the stage where all the stored plastic flexible bags are used, the outer container 3 is disassembled and folded or unfolded, and is collected from the consumption place in a stacked and stacked state. After performing processes such as cleaning, inspection, and repair, the storage location P is returned from the consumption location P2.
It is supplied to one vertical bag making simultaneous filling line.

The supply and packaging method has been described above. Next, the edible oil accumulation package used in this method will be described. The edible oil accumulation package of the present invention includes a plastic flexible bag and an outer container that stores the plastic flexible bag.

[Plastic Flexible Bag] The plastic flexible bag 2 is a flat hollow bag as shown in FIG. 6, and is flexible. As described above, the plastic flexible bag 2 is obtained by sealing and separating the continuous cylindrical hollow plastic film, and in this example, three sealing lines are formed. Therefore, the plastic flexible bag 2 is a single rectangular sheet when not filled with edible oil, and after filling with edible oil, has a flat rectangular appearance having a certain thickness (so-called cushion type). ).

Because of the flat rectangular shape as described above,
The edible oil can be stably placed in a horizontal state, and when the filled edible oil is discharged by cutting the corners, the edible oil can be smoothly discharged simply by pressing and handling from above. Further, in the above embodiment, since the spout is not limited to a fixed position as in the conventional container, any position of the corner portion may be cut, and there is a high degree of freedom. Further, as described above, when taking out from the outer container, it is easy to grasp and handle.

The material of the plastic flexible bag is as follows.
Considering rigidity, gas barrier properties, and sealing properties, it is preferable to form a multi-wall. For example, the outermost layer is a rigid layer using a biaxially stretched polyamide film, the intermediate layer is a gas barrier layer using a saponified ethylene-vinyl acetate copolymer film,
As the innermost layer, a laminated film of a sealant layer using a linear low-density polyethylene film is used.

In filling the edible oil into the plastic flexible bag, a certain range of the filling rate is required in consideration of maintaining the strength of the ruptured bag when the edible oil-filled bag is housed in an outer container and taking out workability. (Filling amount [cc] / surface area of plastic flexible bag [cm ² ]) is preferable. That is, the filling rate of the edible oil is preferably 0.6 to 2.4. By doing so, even if several layers are stacked horizontally and stored in the outer container, the breakage resistance can be maintained, and oil does not splash when the plastic flexible bag is opened.

If the filling rate is less than 0.6, the discharge efficiency at the time of opening the bag filled in the outer container is poor, and the bag is easily moved by vibration when stored in the outer container. In addition, the amount of resin used for the film relative to the packaging capacity of the edible oil increases, which is disadvantageous in cost. On the other hand, if the filling ratio exceeds 2.4, the sheet strength is not always sufficient, and the sheet is likely to be broken when dropped when handled. Incidentally, specific examples of the filling rate and the performance are as follows.

[0041]

EXAMPLE 1 Using the simultaneous bag-filling and packaging method shown in FIG. 2, a length of 310 mm, a width of 200 mm and a width of a horizontal seal of 15 m were used.
m, a plastic flexible bag (before filling) in a three-sided (three-sided body-to-body type) pillow-packed form having a three-layer wall with a vertical seal width of 15 mm. Here, the breakdown of the three-layer wall is a rigid layer (biaxially stretched nylon film, film thickness 15 μm).
m), a gas barrier layer (saponified ethylene / vinyl acetate copolymer film, film thickness 12 μm), and a sealant layer (linear low-density polyethylene film, film thickness 12 μm).

Next, when the edible oil was filled to a filling rate of 0.9, the length and width of the plastic flexible bag were slightly reduced, and the thickness became about 3 cm. These were stacked in a four-tiered manner at 290 mm length × 350 mm width × 210 mm height by a method as shown in FIG. 3 to produce an edible oil accumulation package. When taking out the edible oil, draining after opening was performed smoothly. In addition, when the plastic flexible bag can be securely grasped by hand and taken out, workability is good and efficient. The plastic flexible bag does not move due to the vibration of the outer container.

[0043]

Example 2 An edible oil accumulation package was produced in the same manner as in Example 1 except that the filling rate was changed to 2.2. In this case, the result was almost the same as that of the first embodiment.

[0044]

Comparative Example 1 An edible oil accumulation package was produced in the same manner as in Example 1 except that the filling rate was changed to 0.2. When removing edible oil, draining after opening is not smooth. Also,
When the plastic flexible bag is grasped by hand and taken out, it is easily bent and unstable. The movement of the plastic flexible bag was caused by the vibration of the outer container.

[0045]

Comparative Example 2 An edible oil accumulation package was prepared in the same manner as in Example 1 except that the filling rate was changed to 2.6. When the edible oil was taken out, discharge after opening the container became sudden and leaked from the tray. Also, when the plastic flexible bag is gripped and taken out by hand, the gripping force does not work sufficiently due to its thickness. Moreover, when it fell, there was a thing that a part was torn. Due to the vibration of the outer container, the cushioning force between the plastic flexible bags is low.

[Outer Container] (See FIG. 7) On the other hand, as shown in FIG. 7, the outer container is formed of, for example, a plastic plate such as high-density polyethylene and is foldable. That is, the outer container 3 includes a bottom plate 31, four side plates 32, and two lids 33, and adjacent portions are connected to each other by hinges H. Therefore, it is possible to easily fold (including unfolding) the three-dimensional outer container 3 by bending the hinge portion H, and as a matter of course, assembling is also easy. In addition, each of these plates has a hollow double-walled structure having a hollow portion between the outer wall and the inner wall, so that an impact at the time of transportation accident can be reduced.

Although the present invention has been described above, the present invention can be modified without being restricted to the embodiments and the examples. The material of the plastic flexible bag may be a material having a strength capable of being filled with edible oil, and may have more than three layers. As long as the outer container is foldable, its unfolding blank is free. In addition, edible oil is used in principle, but it goes without saying that the principle of the supply and packaging method and the stacked package of the present invention can be applied to oil similar to that.

[0048]

The supply and packaging method and the plastic flexible bag of the present invention are more convenient in removing oil than the glass bottle, plastic bottle, metal can or standing pouch, and are very economical with little residual oil loss. In addition, there is no danger of injury or the like at the cut end of the opened mark like a can container. Further, there is no need to use an outer container having a partition wall such as a standing pouch.

The supply and packaging method and the plastic flexible bag of the present invention can be filled simultaneously with the filling of contents by a vertical bag simultaneous filling and packaging system. In comparison, the work area is compact, and there is no need to prepare a standing pouch in advance. Conventionally, it is necessary to prepare an empty glass bottle, a plastic bottle, a metal can, or a standing pouch in advance at the time of filling at a storage place, but in the supply packaging method and the plastic flexible bag of the present invention, this is not the case. It is completely unnecessary and packaging costs are reduced. Further, since the volume after use is almost eliminated, disposal is easy, and even if collected, storage is easy.
