Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disposable dust bag that is widely used as a dust bag for all types of vacuum cleaners that has a different mounting structure depending on the model.

[0002]

[Prior art]

 Conventionally, a disposable dust bag has a support A made of paperboard having an inlet port on the surface of a bag body B made of paper or the like having an inlet port, and the support ports A are attached so that their inlet ports are aligned with each other. It is a thing. This type of dust collecting bag has a shape of the bag body B itself and further of the supporting body A, depending on the shape and mounting structure of the dust collecting chamber of the target vacuum cleaner, or the intended function of the dust collecting bag. The shape, the position of the holes and notches formed in the support, the shape of the notch, and the position of the guide (perforation) for bending and dividing the support in parallel are different from each other. Those are known (for example, Japanese Utility Model Laid-Open No. 58-181358, Japanese Utility Model Laid-Open No. 60-2454, Japanese Utility Model Laid-Open No. 60-36844, Japanese Utility Model Laid-Open No. 60-97561, Japanese Utility Model Laid-Open No. 61-). 51150, etc.). However, these are all dedicated models with a special mounting structure.

After that, commercially available vacuum cleaners have been gradually weeded out, and on the other hand, development of disposable dust bags that can be shared by various vacuum cleaners is also in progress. As the basic ones, for example, many drawings disclosed in Japanese Utility Model Publication No. 63-76245 and Japanese Utility Model Publication No. 63-103855 and those disclosed in Japanese Utility Model Publication No. 3-58256 are known. .

[0006] FIG. 3 is a schematic view of a dust bag that is currently commercially available for use with each model, FIG. 3 (a) is a front view, FIG. 3 (b) is a cross-sectional view in the YY direction, and FIG. ) Is a cross-sectional view in the XX direction. This commercial product is considered to be a practically improved product shown in FIG. 17 of Japanese Utility Model Laid-Open No. Sho 63-76245. As shown in Fig. 3, the basic structure of the conventional (commercial) dust collecting bag has the inlet (1) in the center and the long side in the middle of one side. Quadrangular shape with rectangular notches (2) arranged so as to have a guide line (3) dividing the support along the side at the end of the support having a side facing one side The support A having the above-mentioned structure is arranged such that the respective introduction ports are aligned with the surface of the rectangular bag body B having the introduction port, and one side of the support A having the rectangular notch (2) is the bag body B. The end of the support, which is orthogonal to the longitudinal direction of the bag and has a side adjacent to the side with the rectangular notch (2) (90 degrees to the right), is located outside the right edge of the bag body B. This is a collection of vacuum cleaners, which are pasted together and on the surface of the bag body B, explanations on how to adapt to various vacuum cleaners are arranged. It can be seen that the bag. Further, a mounting hole (4) is formed in the middle of the side of the support portion protruding from the side edge of the bag body B.

Here, the meaning of expressing the support A as a quadrilateral means that the impression when viewed as a whole looks almost (roughly) a quadrilateral, and is geometrically stated. It does not always match the quadrilateral. For example, as shown in Fig. 3, there are some corners at the two corners of the support, and on both sides of the guide wire (3), there are small corrugated notches that assist the separation cut. Etc., or the definition of various notches in various parts of the support is not limited to not only being surrounded by perforations or the planned notch location but also having notches already formed. Because of this, there are cases where it cannot be called a straight edge.

The role of the guide line (3) is that the size of the support can be adjusted by cutting at the position of the guide line (3), and the width of the slider for fixing the support is different. It is intended to be applied to. The function of the rectangular cutout (2) is to adapt to a model in which the fixed claw is lowered to fix the support, and is to form a space in which the fixed claw is lowered. Furthermore, the mounting hole (4) is for adapting to a model in which the fixing pin for ensuring the positioning of the support is protruding. Will be inserted. The other two U-shaped cutouts (6) and (7) are for avoiding the positions of the protrusions and levers on the mounting part of the specific model, and further near the guide line (3). The large hole (8) by the side is for not interfering with the function of the optical sensor arranged for another purpose. The packing (9) provided around the inlet (1) is for making the joint dense.

However, it should be noted here that the U-shaped notch (6) cannot be used as a substitute for the mounting hole (4) in relation to the inlet (1) and the position of the cleaner hose. Depending on the model of the vacuum cleaner, it may be better not to cut out the above various cutouts.Therefore, the cutouts are not cut out from the beginning, but can be easily cut out, but the cutout is the planned area. In many cases. Therefore, notches not specifically mentioned in this specification mean both the notch from the beginning and the planned notch area.

On the other hand, the relationship between the support A and the bag body B requires that the dust bag expands to the set dust collecting capacity within the predetermined dust collecting chamber volume of each vacuum cleaner. For this reason, in the bag body B itself in recent years, the surface of the bag shown in the width direction perpendicular to the long axis of the rectangular bag having a bellows-like configuration and the width direction orthogonal to the long axis is vertically long in the front view of FIG. The shape shown in is used.

In this case, generally, the bag has a dimension ratio represented by (long axis dimension / width direction orthogonal to the long axis) of about 1.9 to 2.3 and width dimension of about 12 to 14 cm. Is restricted to. On the surface of the bag, a support A having a dimensional ratio (major axis dimension / minor axis dimension) of about 1.1 to 1.2 and a minor axis dimension of about 10 to 11 cm is attached. Since it is difficult to make both ends of the support stick out from both side edges of the bag body, it is necessary to position the support at the center in the width direction of the bag body or to move it either in the width direction of the bag body. You will let it protrude on one side.

[0010] Either the gap or the other will be projected.

Therefore, even if this commercially available product is divided by the guide wire (3) to reduce the size of the support, the position of the inlet as a dust bag matches the hose mounting position of various cleaners. In consideration of ease of insertion of the mounting hole (4) to the fixing pin of the vacuum cleaner, the rectangular notch (2) of the support body 1 One side is orthogonal to the length of the bag body B, and the end of the support (having the mounting hole (4)) having a side 90 ° to the right of the side with the rectangular notch (2) is the above-mentioned bag. It is presumed that they were pasted together while protruding from the right side edge of the main body. The background of the above description can be easily understood by looking at the relationship between the drawing of the commercially available product shown in FIG. 3 and FIGS. 17 to 19, and especially FIG. 17 of Japanese Utility Model Laid-Open No. 63-76245.

Further, the positional relationship between the upper and lower sides of the dust collecting bag composed of the support A and the bag body B shown in the front view of FIG. 3A, that is, orthogonal to the long axis (longitudinal) of the bag body B. The support bag A with the rectangular notch (2) on the lower side and the end of the support with the guide line (3) on the upper side. When viewed in terms of positional relationship, when the dust-collecting bag is used, the margin portion of the surface of the bag body B is read from above in the lateral direction (width direction of the bag body) and sequentially downward. There is a description of the support A handling description. This explanation is for the purpose of avoiding confusion in the practical use of consumers and ensuring reliable usage of the target model. Therefore, the end of the support with the guide line (3) that is used most frequently is used. The state of cutting from the guide wire (3) of the section and the model that can be adapted by that are shown, and the effects of each cutout section are sequentially described in the longitudinal direction of the bag body B. Therefore, according to this description, it is designed to fit at least 6 different models.

[0012]

[Problems to be solved by the device]

 However, there are many complaints about this type of common type dust bag, such as dust leakage and dust scattering during replacement and removal, and in extreme cases there is a complaint that the fixing pin in the vacuum cleaner is broken. The present inventors have conducted research under the hypothesis that the defective phenomenon occurring here is due to the strain deformation generated in the dust bag supporting body portion and the local damage of the bonding between the support body and the bag body. As a result of repeated efforts, the cause of this defective phenomenon is due to the consumer's inadequate handling of the support part in order to adapt to the target model, and the source of this inconvenience is the construction of the dust collection bag. The present inventors finally completed the present invention by investigating the relationship between the shape of the supporting body and its position and the position of the explanatory text on the bag body.

Therefore, the object of the present invention is to make sure that the consumer can properly handle the target model, prevent the occurrence of dust leakage and dust scattering, and facilitate the alignment with the vacuum cleaner. The object of the present invention is to provide a dust bag that can be shared by at least eight types of electric vacuum cleaners without causing damage to the fixing pin due to certainty.

[0014]

[Means for Solving the Problems]

 The present invention is intended to achieve the above-mentioned object, and its structure is a rectangle in which the introduction port (1) is arranged in the center part, and the long side is aligned with one side in the middle of one side. Quadrilateral support A having a notch (2) and a guide line (3) for dividing the support along the side at the end of the support having a side facing one side thereof. However, the mutual introduction ports are aligned with the surface of the rectangular bag body B having the introduction port, and one side of the support A having the rectangular notch (2) is orthogonal to the length of the bag body B. The end of the support having a side adjacent to the side having the rectangular notch (2) is attached so that it is protruded from the side edge of the bag body B. On the surface of the dust collection bag for the electric vacuum cleaner, the explanation of how to adapt to various electric sweepers is arranged. Body A has a rectangular cutout (2) with an inlet (1) in the center and a long side along the middle of one side. A guide wire (3) for dividing the support along the side is provided at the end of the support having a side opposite to the side where the part (2) is present, and further to the left of the side where the rectangular cutout (2) is present. V-shaped notches (5) are arranged in the middle of the sides adjacent to each other at 90 degrees, and the support A is attached to the bag body B in a rectangular shape of the support A. One side of the cutout (2) is orthogonal to the longitudinal direction of the bag body B, and when the side of the rectangular cutout (2) is viewed downward, the V-shaped cutout (5) is formed. The end portion of the support having a certain side is attached to the bag body B in a state of protruding from the left side edge of the bag body B.

FIG. 1 is a schematic view of a dust bag of a common type for each model according to an embodiment of the present invention. FIG. 1 (a) is a front view, FIG. 1 (b) is a cross-sectional view in the YY direction, FIG. 1C is a sectional view in the XX direction. The contents of the present invention will be described below with reference to the drawings. However, many of the requirements of the present invention are common to the commercially available (conventional) products shown in FIG. 3, and all play the same role. The role that the common requirements bring has already been explained in the section of the prior art. is there . Therefore, here, a duplicated description will be avoided, and the points where the present invention is different from the conventional products will be mainly explained.

The difference between the present invention and the conventional product is the difference between FIG. 3 (conventional product) and FIG. 1 (the present invention). That is, the main points of the difference (improvement of the present invention) are summarized as follows. 1) The "mounting hole (4)" of the conventional product has been changed to the "V-shaped notch (5)", 2) "The side with the rectangular notch (2)" and "Mounting" The positional relationship with "the side with the hole (4) (V-shaped notch (5))" was changed from "adjacent to the right 90 degrees" in the conventional product to "adjacent to the left 90". 3) When the positional relationships of the dust collecting bags are compared under the same conditions, the "end of the support body having the side with the mounting hole (4) (V-shaped notch (5)) sticks out. The direction in which the conventional product is the "right side edge of the bag body" has changed to that of the "left side edge of the bag body." 4) The "guide line (3)" of the conventional product has multiple Increasing to "guide line (3), (3 ')",

First, the role of the difference 1) is to produce the following advantages as compared with the conventional product having the “mounting hole (4)”. That is, a. Since the position of the fixing pin of the vacuum cleaner can be visually checked in the V-shaped space of the V-shaped notch (5), the distortion of the support due to the forced insertion can be prevented, and this distortion of the support occurs due to this. The dust leak that had occurred is eliminated. c. Since there is a space in the upper part of the V-shape, there is no element to apply the force to push down the fixing pin with the support and the force to lift the fixing pin when attaching or detaching the dust collecting bag. It does not break, and there is no damage to the bonding part between the support and the bag body caused by the force of prying, so there is no accident of spilling dust inside the bag.

Due to the above a, b, and c, the problems of dust leakage, dust scattering, and damage of bonding, which have been caused by the consumer's unreasonable mounting, will be greatly improved. Incidentally, it is unexpectedly difficult to make a small hole in a paperboard, and the paperboard often remains in the hole that should have been made. This residual paper is manually removed, but the productivity of this removal is poor. Compared with this, since no residual paper is generated in the V-shaped notch, the above-mentioned advantage is added to the manufacturing in that the manual work for removing the residual paper can be omitted. Next, the importance of the above difference 2), together with the difference 3), brings about the following advantages over conventional products. That is,

D. When the consumer processes the support A to apply it to the target model, the handling operation is such that the left hand firmly fixes the protruding end of the support A while the right hand removes the support part. It was possible to secure a handling environment in which the operator can grasp the support and cut out the support part to be removed. e. The environmental condition of d above is such that the part of the support having the guide line that is most frequently used can be located above the length of the bag body.

Supplementing the advantage of d, the conventional product is the same as the hand shown in d in view of the arrangement of the explanatory text shown in FIG. 3A and FIG. However, the difference here is that in the work that follows the flow of the description of conventional products, the fixing of the end of the support of the left hand is difficult because the bag body existing beside the support interferes. In a difficult state. Moreover, consumers are not familiar with the importance of ensuring this operation. Therefore, since the removal work with the right hand is attempted to proceed with the left hand support end being insufficiently fixed, a force is applied to the bonding portion between the support and the bag body in the direction of peeling the support. Therefore, the probability that local damage will occur at the bonding portion is extremely high.

Alternatively, since the force is not concentrated on the planned cutting portion, the cutting operation becomes difficult, and when further force is applied in that state, the support body is peeled off from the planned cutting portion and the support body is distorted. The probability of becoming is also high. This poor cutting operation deteriorated the adhesion of the support to the vacuum cleaner, and, together with the local destruction of the pasted part, was the main cause of the dust leakage complaints that occurred in the market. Of. However, even with commercially available products, it is possible to fix the support with the left hand from the direction of the support protruding from the bag body and perform the cutting operation with the right hand, but the explanation is reversed and the contents are legible. Due to the difficulty involved, such treatment is generally rare. The number of consumers who use the support of commercially available products as they are and fix it with their right hand and perform cutting work with their left hand is much smaller than the number of specific left-handed people, which is extremely rare. The cause of such a phenomenon was first clarified by a follow-up study by the present inventors.

Therefore, in the support A of the dust collecting bag of the present invention, the V-shaped notch (5) in the middle of the side adjacent to the side having the rectangular notch (2) at 90 degrees left, When the V-shaped notch (5), the side with the rectangular notch (2) and the long U-shaped notch (7) in the middle are arranged in a notched state. The cutting work can be done with the right hand, and it is not necessary to turn the dust bag upside down, which is desirable.

Further, by utilizing the advantages of d and e described above, as shown in FIG. 1, the explanation given to the margin on the surface of the bag body is from the upper side of the bag body B to the longitudinal direction of the bag body. It is desirable to arrange them so that they can be read in the width direction and / or in the longitudinal downward direction. This placement of explanations is desirable because it will not obscure the contents of the fixed left hand and obscure the contents, and it will bring about the advantage that the removal work can be surely done naturally while reading the explanation.

The difference 4) is to widen the adjustment range of the size of the support body, which increases the applicable models by 2 types and can be applied to 8 types.

FIG. 2 is a schematic diagram showing the bonding shape of the support and the bag body adopted in the embodiment of the present invention, showing the shape of the part where the back surface of the support and the bag body surface are bonded, The bonding part (10) is shown by hatching. On the other hand, similarly, FIG. 4 shows the shape of the bonding part of a commercial product. Generally, the back surface of the support A and the front surface of the bag body B are bonded to each other in a donut-shaped region having a substantially constant width of about 1.0 to 1.5 cm along the mutual inlets. Often done in. The bonded portion of the commercially available product shown in Fig. 4 also has a donut shape. This is because once the joint area strength is satisfied, it is desirable to prevent the occurrence of obstacles that occur due to the bonding area being too large (for example, a failure that the excessive bonding area prevents sufficient expansion of the bag body). It is presumed that it was

On the other hand, in the shape of FIG. 2 (product of the present invention), the outer shape of the bonding portion is a substantially semi-circular arc centered on the introduction port, and two ends of the semi-circular arc are linearly extended. It has a horseshoe shape that is drawn by a line and a line that connects the ends of the two lines at a substantially right angle.The arrangement is such that the side that is a line that connects the ends of the two lines at a substantially right angle is a guide line ( It can be seen that it is arranged at a position facing the support having 3) and substantially parallel to the guide line (3) at a predetermined interval. In the case of the bonding part shape shown in FIG. 2, the bonding of the support part where the guide wire (3), which exerts the greatest force at the time of local excision of the support, is located, is strengthened with the bag body. It is desirable because it is effective in preventing peeling accidents at the bonded part.

Since the above V-shaped notch (5) replaces the mounting hole (4), the opening may have a size of about 8 to 5 mm at the most, and both ends of the opening may be slightly different. It is desirable to keep the radius of curvature (R) so that the fixing pin can be guided more easily.

The dust collecting bag of the present invention is for commercial use by bending one or both of the portions of the bag body that are out of the support body in the longitudinal direction to the back side of the support body.

[0029]

【Example】

 In the center, an inlet (1) is provided with a rectangular cutout (2) in which the long side is placed in the middle of one side along one side. ) There are two guide lines (3) and (3 ') that divide the support along the side and a rectangular notch (2) at the end of the support that has a side opposite to the side A V-shaped cutout (5) is formed in the middle of the side adjacent to the left side 90 degrees, and a U-shaped cutout (6) is also formed in the middle of the side adjacent to the right side 90 degrees. The quadrilateral paperboard support A having the above was attached to the surface of a rectangular paper bag main body B having an inlet on the surface so that both inlets were aligned. In this case, the positional relationship between the support A and the bag body B is such that one side of the support A having the rectangular cutout (2) is orthogonal to the longitudinal direction of the bag main body B, and the rectangular cutout is formed. When the side with (2) is viewed from below, the end portion of the support having the side with the V-shaped cutout (5) is attached so that it is protruding from the left side edge of the bag body B. It was a dust bag. At this time, the V-shaped notch (5) is assumed to be in a notched state, and the V-shaped notch (5) and the side with the rectangular notch (2) have a U-shape that is long in the middle. In addition to the shape cutout (7), a large hole (8) near the guide wire was also inserted. In the bag body margin of this dust bag, when the same bag body as above was viewed in portrait orientation, a description of handling was printed, reading from the top of the bag body in the width direction and then downward (Fig. Then part omitted). The appearance of the entire dust collecting bag is shown in FIGS. 1 (a), 1 (b) and 1 (c), and the shape of the bonded portion of the bag body B and the support A is shown in FIG.

[0030] With 240 sheets of the embodiment (product of the present invention) and 8 types of commercially available vacuum cleaners that can be adapted, 30 housewives were randomly selected who had no experience of using a common type dust bag. Skilled investigators conducted an experiment in which eight types of models per person were equipped with dust-collecting bags, provided that no instruction was given to them, no help was given, and no questions were answered. The mounting state, the distortion of the support, and the peeling state of the dust collecting bag were inspected. In addition, housewives after the experiment listened to their impressions after use one by one.

As a result, none of the eight models were judged to be poorly mounted, the one with the large distortion of the support, and the one with the dust collecting bag peeled off. The impression after use was that "it can be used by anyone". It was something to do.

For comparison, a commercially available common type dust collecting bag manufactured by AK Company was purchased. The overall appearance of this dust bag is shown in FIGS. 3 (a), 3 (b) and 3 (c), and the shape of the bonded portion between the bag body B and the support A is shown in FIG.

The same experiment as in the example was repeated except that the number of prepared dust collecting bags was 180, the number of housewives to experiment was 30 of other people, and the target model was changed to 6 types. . As a result, none were judged to have bad mounting or large distortion of the support, but two cases where the dust bag was about to peel were detected. There were a total of 5 people who responded that the impression after use was that the description was difficult to hide because it was hidden in the hand and that it was difficult to cut it because it was difficult to fix it by holding it by hand.

The above results show a part of the excellent practicability of the present invention.

[Effect of device]

 Since the present invention has the above-mentioned configuration, the consumer can properly handle and handle the target model, prevent the occurrence of dust leakage and dust scattering, and easily position it in the vacuum cleaner. It is an excellent idea with the effect that the fixing pin will not be damaged by doing so reliably. This dust bag is also a dust bag that can be shared with the eight main types of commercially available electric vacuum cleaners.
