Description

DETAILED DESCRIPTION OF THE INVENTION (1) Purpose of the invention (industrial application field) The present invention provides an inner bag suitable for storing light-weight fine powder or granules one after another. It concerns a container with

(Prior Art and Problems to be Solved) Collapsible containers made of cardboard or the like have been widely used since they can be folded to reduce their volume during transportation and storage, which is extremely advantageous from the perspective of cost reduction.

However, on the other hand, it is difficult to completely seal this type of container if it is left alone, so when storing highly hygroscopic items such as certain foods and confectionery, metal foil is used. It was common practice to seal the packaged item in a synthetic resin film inner bag and then store it in a foldable container.

However, with these conventionally known packaging means, it is common to fill the bag all at once at the beginning of packaging, and if the item to be packaged is relatively large, the inner bag itself is There was no particular difficulty in making effective use of the inner space of the container itself by matching the shape of the packaged product or, if the packaged product was granular, by appropriately applying vibrations during filling.

But inside? In the double-walled container described above, when extremely light and fine powder particles are to be stored one after another over a period of time, the inner bag may be made of a flexible material such as synthetic resin film. Even if the inner bag itself is uneven, the actual space in which the packaged items can be stored is inevitably reduced. Furthermore, when the outer box is made to be foldable as described above, folding the outer box for storage etc. causes creases in the inner bag, which causes unevenness of the inner bag during use as described above. This results in the undesirable situation described above.

In such cases, even if measures such as applying vibration to the container are applied, if the packaged item is lightweight, the added inertia will be small, and the unevenness of the inner bag will be forcibly deformed from the inside, causing it to bulge. It is not always possible to say with certainty.

In addition, after assembling the folding type outer box one by one, inserting a bulging inner bag made of flexible film or the like inside the box and joining the two would increase manufacturing costs, and would require the use of inexpensive materials such as cardboard. This goes against the purpose of reducing costs by using the method, and is virtually impossible.

The present invention has been made in order to cope with such a situation, and the outer box is assembled by gluing predetermined parts of the outer box, which is made of cardboard or the like so that it can be folded freely, and is unfolded in a flat state before assembly. When the inner bag expands along with this, there is no local tension or wrinkles on the surface of the inner bag, and the inner bag expands almost along the inner surface of the outer box, improving the characteristics of the stored items. The object of the present invention is to provide a container in which the space inside the container can be surely utilized for storage regardless of the situation.

(2) Structure of the invention (technical means and effects for solving problems) In order to achieve the above object, the present invention converts a known foldable box made of cardboard or the like into a planar shape. The inner bag made of a flexible material, which has been constructed in advance, is placed in a predetermined position on the unfolded surface of the outer box in a folded state and adhered to the inner bag. It is configured to be fixed along the

As a result, the inner bag is adhesively fixed to the inner surface of the outer box so that it is in contact with the inner surface of the outer box over almost the entire surface, so that the inner bag will always be stretched along each side of the outer box when folding or assembling. This results in a container with virtually no dead space.

(Description of Examples) Fig. 1 shows a developed view before assembly of a known rectangular parallelepiped outer box container that is assembled by folding cardboard, etc. As is well known, there are four rectangular faces A and B. , C and D, and create a gluing surface E on the outside of the A surface, and
At the end of each surface (upper and lower ends in the figure) there is a folded opening/closing lid forming part F.

It makes G. Surface E of such a member, between A, and surface A
, along the lines between B, B and C, and C and D so that surfaces A and 01 face B and D, and glue them to surface E to make them face E. It is easy to understand that a rectangular parallelepiped container can be constructed by gluing the F and G parts, folding the F and G parts, and putting a lid on the lid.

The embodiment shown in FIG. 1 is intended to be used as a waste toner collection container of a copying machine, and for this purpose, the waste toner discharged from the re-leaning device, which will be described later, is collected in the surface 11:U. The toner receiver has an opening 3 for attaching a member and an opposing opening 4a through which light from a light emitting element for detecting the amount of toner passes through the container.

I have 4b.

The outer box as described above is provided with an inner bag made of cellophane or other thin film to prevent the stored toner from dissipating. The inner bag 2 is, for example, as shown in FIG.
Forming a thin film into a ring] ~, when this is made into a flat shape, the width W is equal to the width of surfaces A and B shown in Figure 1 (the length when viewed in the left-right direction in the figure), and the length is is formed to be appropriately longer than the length of surfaces A and B (the length in the vertical direction shown in the figure).

Place the inner bag 2 shown in Fig. 2 at the positions A and H in the first drawing as shown by the chain lines, apply adhesive to the inner bag as shown by hatching 1 in the same figure, and then Fold sides C and D around X-X, and overlap and adhere the adhesive edge to the other surface of the inner bag.

Adhesive is also applied to the periphery of each of the openings 3.4a and 4b to prevent the openings from being blocked by movement of the inner bag. It is also possible to previously provide a similar opening in the inner bag at a portion corresponding to the opening 3.

After the inner bag is adhered to the outer box in this way, the adhesive surface E can be used to form a box body.

Figure 3 is an end view showing the state at this time, and the box bent so that the surfaces A and B and the surfaces C and D face each other as described above is flat as shown by the solid line in the figure. It has a shape,
By standing this up in the direction of the arrow α, it becomes a box as shown by the two-dot chain line in the figure, and then by folding the lids F and G, an outer box is formed.

As can be seen from the figure, no tension is applied to the inner bag fixed with adhesive l even after the inner bag 2 is erected, even when the outer box is folded in its width direction. There will be no wrinkles.

In addition, the length is such that it fits the inner bag when standing up.
By predetermining the length of the part protruding from sides A to 9 of the inner bag in the longitudinal direction and heating/ruling it, even when the inner bag swells, the shape conforms to the end surface on the lid side of the outer box. can form an inner pouch.

Inside the outer box configured in this way, the inner bag made of thin sheet material is well attached to at least surfaces A, B, C, and D and does not move relative to each other, so the space inside the outer box can be fully utilized. It is possible to store a large amount of waste toner.

FIG. 4 is a perspective view showing a separately provided toner quantity measuring member 5 attached to the outer surface of such an outer box.

The toner amount member 5 is connected to a bottom surface 5b corresponding to the opening 3 of the outer box, and has an opening 5a for receiving a pipe S for guiding toner discharged from a cleaning device (not shown). shall be.

The inner bag 2 may be made of a material that is relatively flexible and does not allow fine particles such as toner to pass through, but if the outer box is made of paper, it is better to use cellophane or OPP, which has good adhesion to this material. .

In addition, since the inner bag is formed into a sealed shape by heat sealing, it is preferable to apply an antistatic agent to prevent toner from adhering to the inner surface of the inner bag and impairing the function of the detection means. In order to incorporate a surfactant, it is preferable to use cellophane with a polyethylene coating formed on its inner surface.

Other embodiments of the present invention are shown below in FIG.

These examples also show cases where the present invention is applied to a waste toner collection container.

Fig. 6a shows a case of a gusset type inner bag, that is, a bag in which the bag body is preformed in a three-dimensional shape.
Such an inner bag is formed into a flat shape by folding it along the line H--H in FIG. 6a as shown in FIG. 6b.

FIG. 5 is a developed view of the outer box, and portions corresponding to those of the previous embodiment, such as each side of the box and the lid, are designated by the same reference numerals.

In the case of FIG. 5, the surface corresponding to the surfaces A and C of the outer box in the above-mentioned embodiment is placed on the line Y +
Y+, Y2- Make a crease so that it can be bent along Y2. The detection light passing openings 4'a, 4J) The knur receiver opening 3, etc. are not particularly different from those described above.

``Adhesive 1 shall adhere to the areas indicated by the hatches in Figure 5.''

Place the expanded outer box as shown by the two-dot chain line 6 in the same figure, and turn the surfaces At and C2 into surfaces A2 . Adhesive 1 is adhered to the inner bag by rotating as shown by the arrow around the axes Y2-Y2 and Y+-Y+ so as to overlap CI. At this time, at the same time, the gluing portion E is superimposed on the surface and the outer box is formed by gluing.

Note that the inner bag should have an opening in a portion corresponding to the opening 3 for the toner receiver in the outer box, and the circumferential line of the opening should also be glued.

As a result, the outer box and inner bag are configured as shown in the end view in FIG. 7, and they are joined at the boundary between surfaces A1 and 01 and C2, surfaces C1 and B1, and surfaces B and A2. Therefore, if this is made to stand up as shown by the two-dot chain line in the figure, the inner bag will be fixed at the four corners inside the outer box, and a double container will be formed without any part of the inner bag being stretched or wrinkled. That will happen.

~ Thereafter, the folding lid parts F and G are folded in the same manner as a well-known folding box to form a container, and the toner receiver has an opening of 3vc.
For example, the member 5 is attached to the toner receiver in the same manner as shown in FIG. 4 above. The material of the inner bag may be the same as that of the previous embodiment.

Since the toner collection container according to this embodiment is constructed as described above, it can be used in copying machines that use dry toner in the same way as conventionally known waste toner storage containers, and when storing and transporting toner before use, the toner collection container can be used easily. Since the receiver can be folded into a flat shape with the parts separated, the outer box and inner bag can be made of inexpensive materials as mentioned above, and the cost of storage and transportation is extremely low, making it easy to copy. It is extremely important that it contributes to reducing the cost of the entire machine.

Although the embodiment in which the present invention is applied to a copying machine has been described above, the present invention is not limited to this. It is easy to understand that it is suitable for such cases as well.

(3) Effects of the Invention The present invention has the structure and operation described above, and when the outer box is assembled, the inner bag expands along the inner surface of the outer box, making it easy to store powder and granules. The generation of dead space can be minimized and the capacity can be substantially expanded.

Therefore, a substantially airtight container can be constructed using a well-known inexpensive foldable outer box, which, in combination with the low cost of the box itself, greatly contributes to reducing storage and transportation costs.
