Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container filled with a recording material powder such as toner.

[0002]

BACKGROUND OF THE INVENTION Conventionally, a container filled with toner used for copying has been made of, for example, metal, paper, plastic, or the like. At present, the main body of the container is mainly made of plastic in a substantially cylindrical shape. Containers are widely used. By the way, in the case of preparing several containers having different toner filling capacities depending on the type of copying machine, containers having different capacities have been prepared so far.

However, in order to mold a number of toner-filled containers, a large number of different molds are required, and the cost is extremely high. Furthermore, in the conventional toner filling container, it is difficult to form an extra space when the high density filling of toner is performed, that is, it is difficult to form the air reservoir, and even if the toner filling container is loaded into the copying machine, the toner is not filled. There is a problem that it does not easily flow into the hopper of a copying machine.

[0004]

DISCLOSURE OF THE INVENTION It is a first object of the present invention to provide a low cost container which can be easily applied to a variety of types. A second object of the present invention is to provide a container that is easily filled with powder so that the powder can be smoothly discharged from the opening.

The above-mentioned object of the present invention is a container filled with powder, which comprises a main body and a lid, and the main body is integrated by fitting at the neck. This is achieved by a container characterized by comprising a base portion and a head portion. With the above structure, the base portion and the head portion can be molded separately, so that even if several toner filling containers are required, only one head portion having a complicated structure is required, and It suffices to prepare only a few base parts that can be of a simple shape, and the cost is accordingly reduced. In other words, when containers with different volumes are required, it is possible to deal with them by using a common mold with a complicated die and a high cost head body, and by making the volumes of the base bodies different. For example, it suffices to replace only the base portion with one having a desired volume, and since the base portion has a simple structure, the die cost is low and the overall cost is low.

Further, if the base portion and the head portion are separately configured, the toner is filled into the base portion, so that the volume of the head portion is always included in the container. Therefore, when the container is upside down loaded in the copying machine, the toner smoothly flows out into the hopper of the copying machine. In the above container, a first concave portion is provided in the vicinity of the upper end portion of the base portion along the circumferential direction, an inwardly extending piece extending downward is formed in the head portion, and The protrusion that engages with the concave portion of 1 is configured on the outer wall portion of the head body portion, and the upper end portion of the base portion is fitted into the groove portion formed by the outer wall portion of the head body portion and the inward extending piece. With this configuration, after the toner is filled in the base portion, it can be integrated by a simple operation of pressing the head portion against the base portion, and the toner inside does not leak out at all. It is extremely preferable.

Further, when the base portion is provided with the second concave portion along the circumferential direction below the first concave portion, it is easy to clamp the second concave portion when the toner is filled. This is extremely preferable because the base portion can be easily held and the side wall of the base portion hardly buckles when the head body portion is positioned and pressed against the base portion.

FIG. 4 is a perspective view in a state where the body portion, the head portion and the base portion are separated, and FIG. 4 is a perspective view in a state where the lid portion is slid and opened.

In the drawings, reference numeral 1 denotes a base portion made of a transparent or translucent and relatively soft resin material which constitutes the container A. The base portion 1 is molded into a substantially cylindrical shape having an opening at its upper end. Then, the toner used for copying is filled in the inside of the base portion 1. Reference numeral 2 is a first annular recess formed on the upper side of the base portion 1, and 3 is a second annular recess formed below the first annular recess 2. The outer diameter a of the base portion 1 in the portion where the first annular recess 2 is formed is smaller than the outer diameter b of the base portion 1 in the portion where the second annular recess 3 is formed. There is.

Reference numeral 4 denotes a translucent or opaque head body made of a hard resin material that cooperates with the base body 1 to form the container A, and a slide lid, which will be described later, is arranged at the upper end of the head body 4 so as to face it. An opening 5 for replenishing toner is provided, and a fitting means that is fitted to the base body 1 is provided below the head body 4. That is, the fitting means is composed of an inwardly extending piece 7 that extends downward from the middle of the side wall 6 of the head portion 4 and that has a small thickness and a relatively short length. When the upper end of the base portion 1 is pushed into the groove portion 8 constituted by, both are fitted and integrated. Particularly, in the state of this fitting and integration, the inner extending piece 7
The inwardly extending piece 7 is configured to come into close contact with the inner surface of the first annular recess 2 due to the elastic force of the. Further, at the position facing the first annular recess 2 of the base body portion 1 in the fitted and integrated state of the head body portion 4 and the base body portion 1, the protrusion 9 protruding from the inside of the side wall 6 of the head body portion 4 is formed. This is the projection 9
Is hooked on the first annular recess 2 of the base body 1,
The head portion 4 is prevented from easily coming off from the base portion 1, and since the gap is closed by this engagement, the effect that the toner in the base portion 1 does not leak is enhanced. .. Further, since the lower end 10 side of the side wall 6 of the head body portion 4 is configured to be curved slightly inward, when the head body portion 4 and the base body portion 1 are fitted and integrated, the head body portion 4 is formed. Side wall 6
Adheres to the wall surface between the first annular concave portion 2 and the second annular concave portion 3 of the base portion 1 to enhance the effect that the toner in the base portion 1 does not leak out, and the protrusion 9 and the first annular portion. The locking lock with the recess 2 is made hard to come off.

A flange 11 is provided in the opening 5 for toner supply.
Is provided, and a rib-shaped standing wall 12 for connecting from the surface of the flange 11 to the mounting portion (hopper) of the container A in the copying machine is provided. Reference numeral 13 is a slide lid, and the ridges 14 provided on both side wall portions of the slide lid 13 are configured to be slidable by being guided by the groove 15 formed in the standing wall 12 of the head body portion 4. ing.

Reference numeral 16 is a film for sealing the opening 5, and the film 16 is a standing wall 1 around the opening 5.
2 is welded to the upper surface, and is configured so that the toner in the container A does not leak from the opening 5. The film 16 is provided so as to surround the outer circumference of the slide lid 13. When the slide lid 13 is slid as shown in FIG. 4, the film 16 is peeled off from the upper surface of the standing wall 12. ing. It should be noted that a part of the film 16 is strongly fixed to the head portion 4 so that even if the film 16 covering the opening 5 by the slide of the slide lid 13 is peeled from the upper surface of the standing wall 12, it cannot be removed. Therefore, the slide lid 13 is prevented from being completely removed from the head portion 4. That is, although the toner remains in the container A, if the container A must be removed from the copying machine, and the lid cannot be closed without the slide lid 13, the toner may scatter. With such a configuration, since the slide lid 13 is always left, the lid can be closed, and there is no fear of toner scattering.

The cartridge in which the container A is filled with the toner is manufactured as follows. First, the periphery of the second annular concave portion 3 of the base portion 1 is held by a clamp member, and in this state, the toner is filled so that the base portion 1 is almost full. After this, the head part 4 is placed on top of the base part 1, and when the head part 4 is pushed into the base part 1, the side wall 6
The upper end of the base portion 1 is fitted into the groove portion 8 constituted by the inner extending piece 7 and the both, and the both are fitted and integrated. At this time, since the film 16 and the slide lid 13 are attached to the head body portion 4, the toner will not be scattered to the outside after the head body portion 4 and the base body portion 1 are fitted and integrated.

Since the main body of the container A is molded separately from the base portion 1 and the head portion 4, the head portion having a complicated structure is required even when several toner filling containers are required. 4 only needs to be one type, and it is sufficient to prepare only some of the base portions 1 which have a simple shape, and therefore the cost is low. That is, when toner-filled containers having different capacities are required, it can be dealt with by making the head part 4 having a complicated mold and a high cost in common and making the capacities of the base parts 1 different. In this way, it is only necessary to replace the base portion 1 with one having a desired volume, and since the structure of the base portion 1 is simple, the die cost is low,
The overall cost is also low.

Further, in the integrated structure of the base body portion 1 and the head body portion 4 of the container A, a first annular recess 2 is provided in the vicinity of the upper end portion of the base body portion 1, and the head body portion 4 has a lower portion. Is formed on the side wall 6 of the head body portion 4, and the upper end portion of the base portion 1 is formed on the head body portion 4. Since it is configured to be fitted in the groove portion 8 constituted by the side wall 6 and the inwardly extending piece 7, it is possible to perform a simple operation by simply pressing after positioning the base body portion 1 and the head body portion 4. It can be integrated, and the toner inside does not leak out at all. In particular, in the fitted and integrated state, the inwardly extending piece 7 is configured to be in close contact with the inner surface of the first annular recess 2 by the elastic force of the inwardly extending piece 7.
There are no accidents such as toner leaks. Further, at the position facing the first annular recess 2 of the base body portion 1 in the fitted and integrated state of the head body portion 4 and the base body portion 1, the protrusion 9 protruding from the inside of the side wall 6 of the head body portion 4 is formed. Since the projection 9 is hooked on the first annular recess 2 of the base body portion 1, the head body portion 4 cannot be easily removed from the base body portion 1, and further by this hooking. Since the gap is closed, the effect that the toner in the base portion 1 does not leak is further enhanced. Further, the lower end 10 of the side wall 6 of the head body portion 4
Since the side is configured to be slightly curved inward,
In the fitted and integrated state of the head body portion 4 and the base body portion 1, the side wall 6 of the head body portion 4 is in close contact with the wall surface between the first annular recessed portion 2 and the second annular recessed portion 3 of the base body portion 1. However, the effect that the toner in the base portion 1 does not leak is further enhanced, and the locking lock between the protrusion 9 and the first annular concave portion 2 is hard to come off.

Further, since the second annular concave portion 3 is provided below the first annular concave portion 2, the second annular concave portion 3 is provided when the toner is filled.
It is easy to clamp the annular recess 3 of the
Can be easily held, and buckling does not easily occur on the side wall of the base body portion 1 when the head body portion 4 is positioned and pressed against the base body portion 1. That is, when the base portion 1 and the head portion 4 are integrated with each other, if the base portion 1 is not provided with the second annular recessed portion 3, the bottom portion of the base portion 1 is placed on a table, and the head portion 4 is inserted. Since the base member 1 having a long length and made of a relatively soft material is apt to buckle on its side wall since it is joined by applying a force from above the first annular recess 2 If the second annular recess 3 is provided immediately below, the force is received by the holding member that clamps the second annular recess 3, so that the side wall of the base 1 is less likely to buckle.

Further, since the toner is filled in the base portion 1, a space corresponding to the volume of the head portion 4 is always formed in the container A. Therefore, the container A is inverted in the copying machine. When loaded, the toner will flow out smoothly into the hopper of the copier.

[0018]

[Effect] The container according to the present invention is a container filled with powder, and the container is composed of a main body portion and a lid portion, and the main body portion is integrated by fitting at the neck portion. Since the base part and the head part are formed, the base part and the head part can be molded separately, and even if several toner filling containers having different volumes are required depending on the type of the copying machine, the complicated structure is required. There is only one mold for the head part, and it is sufficient to prepare several molds for the base part that are simple in shape, and the mold structure of the base part is simple, so the cost is low. Since the total cost is low and the toner is filled in the base portion, a space corresponding to the volume of the head portion is always formed in the container. When it is loaded upside down, the toner flows out smoothly into the hopper of the copying machine. With features such as become memorial service.
