Patent Description:
As a device for performing settlement processing by a customer, a self-checkout device and a settlement device are known. For example, the self-checkout device is a device for reading information of a commodity by the customer himself/herself to perform settlement. For example, the settlement apparatus is an apparatus for allowing the customer to perform only the settlement.

The commodity which has been subjected to the settlement processing by using such a settlement apparatus is placed into the bag by the customer.

Such a bag is called a register bag, and for example, a clerk who is in charge provides the register bag to the customer.

In addition, in recent years, there has been a case where the customer brings a bag, and the bag is suspended around the settlement apparatus.

In view of hygiene, there has been known a technique for accommodating a plurality of bags stacked on a drawer shelf such as a holder, and a technique for folding a plurality of stacked bags to be accommodated in a holder. When the bag is contained in such a drawer shelf or holder, it is required that the bag be visually recognizable so that the size and remaining amount of the bag can be known. However, when the take-out opening for taking out the contained bag is large, a plurality of bags may be taken out at a time, and when the take-out opening is small, there is a problem that it is difficult to take out the bag.

<CIT> discloses a dispensing carton for plastic sheet form articles capable of being manufactured from a single blank having removable tear strip defining an exit slot, and having an insert member as part of the unitary construction for holding said articles adjacent to said exit slot.

Hereinafter, the bag storage case <NUM> according to the first embodiment will be described with reference to <FIG>. <FIG> is a perspective view showing the configuration of the bag storage case <NUM> according to the first embodiment from the front side. <FIG> is a perspective view showing the configuration of the bag storage case <NUM> from the back side. <FIG> is a sectional view showing the configuration of the bag storage case <NUM>. <FIG> is a perspective view showing bag storage cases <NUM> that are stacked. <FIG> is a front view showing bag storage cases <NUM> that are stacked. <FIG> is a view showing the structure of the bag storage case <NUM> from the front side. <FIG> is a view showing a relationship between the width Tw of the take-out opening <NUM> of the bag storage case <NUM> and the width Fs of the bag <NUM>.

As shown in <FIG>, the bag storage case <NUM> includes a housing <NUM> and a holder <NUM>.

The bag storage case <NUM> accommodates a plurality of bags <NUM> in the housing <NUM> in a state in which the plurality of bags <NUM> are stacked and held by the holder <NUM>. The plurality of bags <NUM> are held so as to be able to be taken out in the state in which the plurality of bags <NUM> are stacked by the holder <NUM>.

As shown in <FIG> and <FIG>, for example, the bag storage case <NUM> is formed so as to be stackable with additional storage cases.

In the first embodiment, the bag <NUM> is a so-called "register bag". The bag <NUM> includes a main part <NUM>, a pair of handles <NUM>, and a hung part <NUM>. One end of the main part <NUM> is closed, and the other end is open. The closed end of the main part <NUM> forms the bottom of the bag <NUM>. The extending direction of the closed end edge forming the bottom of the bag <NUM> will be described below with reference to the width direction of the bag <NUM>.

The pair of handles <NUM> are integrally formed on the other end of the main part <NUM> on an opening of the main part <NUM> of the bag <NUM>. The hung part <NUM> is provided at one end of the opening of the main part <NUM> and between the pair of handles <NUM>. The hung part <NUM> is formed, for example, with a hole 113a.

The hung part <NUM> is integrally provided with the main part <NUM> so as to be separable from the main part <NUM>. As a specific example, a perforation or the like is formed at the boundary between the main part <NUM> and the hung part <NUM> to separate the hung part <NUM> from the main part <NUM>.

For example, a plurality of bags having different widths are used as the bags <NUM>. As a specific example, three types of bags <NUM> having an L-size having a large width, an M-size having a middle width size, and an S-size having a small width are used. For example, the L-size bag <NUM> has a width of <NUM>, the M-size bag <NUM> has a width of <NUM>, and the S-size bag <NUM> has a width of <NUM>.

For example, as shown in <FIG>, a plurality of such bags <NUM> are stacked and folded at a folded portion <NUM> in the main part <NUM>. Then the folded portion <NUM> is held on a shaft <NUM> in the holder <NUM>, and the plurality of stacked and folded bags <NUM> are accommodated in the housing <NUM>.

As shown in <FIG>, the housing <NUM> includes a pair of first walls <NUM>, a pair of second walls <NUM>, and a third wall <NUM>. The housing <NUM> is formed in a rectangular box shape in which one surface is opened by, for example, a pair of first walls <NUM>, a pair of second walls <NUM>, and a third wall <NUM>.

The pair of first walls <NUM> are opposed to each other at intervals in which a plurality of stacked and folded bags <NUM> are disposed. That is, the pair of first walls <NUM> are opposed to each other so as to accommodate a plurality of stacked and folded bags <NUM>. More specifically, the pair of first walls <NUM> are spaced apart from each other at intervals in which the holder <NUM> for holding the stacked and folded bags <NUM> can be disposed.

The pair of first walls <NUM> are opposed to the stacked and folded bags <NUM> in the stacking direction of the plurality of stacked and folded bags <NUM>. In other words, the pair of first walls <NUM> are opposed to the main surface of the main part <NUM> of the bag <NUM>. For example, the bag storage case <NUM> is placed on an installation surface such that one of the pair of first walls <NUM> is positioned downward. The pair of first walls <NUM> are opposed to each other in the height direction to form a bottom wall and a top wall of the bag storage case <NUM>.

The pair of second walls <NUM> are continuous with the pair of first walls <NUM>. The pair of second walls <NUM> are opposed to each other in the width direction of the accommodated stacked and folded bags <NUM>. The pair of second walls <NUM> are spaced apart from each other a distance larger than the width of the stacked and folded bags <NUM> so that the plurality of stacked and folded bags <NUM> can be disposed. For example, the pair of second walls <NUM> constitute a pair of side walls of the bag storage case <NUM>.

The third wall <NUM> has a take-out opening <NUM> in a part thereof. The third wall <NUM> is continuous with the pair of first walls <NUM> and the pair of second walls <NUM>. The third wall <NUM> includes, for example, a first inclined part <NUM> inclined to the opposing direction of the pair of first walls <NUM>, and a second inclined part <NUM> inclined with respect to the opposing direction of the pair of first walls <NUM> and inclined in a direction different from the direction of the first inclined part <NUM>. Hereinafter, the "opposite direction of the pair of first walls <NUM>" will be described as the "first direction". When the pair of first walls <NUM> constitute a bottom wall and a top wall, the first direction is the lateral, or vertical, direction.

As a specific example, the take-out opening <NUM> is provided in the first inclined part <NUM>. The take-out opening <NUM> is opposed to the folded portion <NUM> of the plurality of stacked and folded bags <NUM> accommodated in the housing <NUM>.

The take-out opening <NUM> extends along the opposite direction of the pair of second walls <NUM>. Hereinafter, the "opposite direction of the pair of second walls <NUM>" will be described as the "second direction". When the pair of first walls <NUM> constitutes a bottom wall and a top wall, the second direction is the longitudinal, or horizontal, direction. The width in the longitudinal direction of the take-out opening <NUM> is smaller than the width of the bag <NUM>. Further, the center, or middle, of the take-out opening <NUM> is larger than both end sides of the take-out opening <NUM> in the first (i.e. vertical) direction. That is, the take-out opening <NUM> has a wide center or middle and narrow ends in the first direction. That is, the width of the take-out opening <NUM> in the lateral (i.e. vertical) direction is different between the center or middle and both end sides, and the width in the center or middle is larger than the width on both end sides. Further, the take-out opening <NUM> is set to have a constant width in the first direction in the center or middle and a constant width in the first direction on both end sides. Moreover, the take-out opening <NUM> is formed to have a curved corner portion.

As shown in <FIG>, the length of the take-out opening <NUM> in the second direction, that is the length in the longitudinal direction, is set by the width of the bag <NUM>. As a specific example, as shown in <FIG>, the take-out opening <NUM> is formed of a first opening 31a provided in the center or middle and a second opening 31b provided on both end sides in the second direction of the first opening 31a and continuing to the center or middle in the first direction.

For example, the width of the first opening 31a in the second direction is constant regardless of the width of the bag <NUM>.

The width of the second opening 31b in the second direction is smaller than the width of the bag <NUM>, and is set as appropriate based on the width of the bag <NUM>. For example, the width of the second opening 31b in the second direction is set as a function of the width of the bag <NUM>.

The first inclined part <NUM> is continuous with the first wall <NUM> forming the top wall and the second inclined part <NUM> in the first direction.

The second inclined part <NUM> is continuous with the first wall <NUM> forming the bottom wall and the first inclined part <NUM> in the first direction.

That is, for example, the first inclined part <NUM> is positioned above the second inclined part <NUM>.

The first inclined part <NUM> and the second inclined part <NUM> are inclined in a direction away from the first wall <NUM> toward a center side in the first direction from the first wall <NUM> side.

In other words, the first inclined part <NUM> and the second inclined part <NUM> are continuous at the center side in the first direction, and the continuous portions of the first inclined part <NUM> and the second inclined part <NUM> are protruded from the outside of the housing <NUM>.

In other words, the third wall <NUM> is formed in a shape that is chamfered by the pair of first walls <NUM>, the first inclined part <NUM>, and the second inclined part <NUM>.

Such a housing <NUM> is formed, for example, by integrally molding a pair of first walls <NUM> and a pair of second walls <NUM> in a rectangular cylindrical or parallelepiped shape, and by covering one of the openings formed by the pair of first walls <NUM> and the pair of second walls <NUM> with the third wall <NUM>. The front side of the case <NUM> is formed by the third wall <NUM>, and the rear side is formed by the opening on the opposite side of the third wall <NUM>.

Note that the housing <NUM> may be configured by assembling a panel that forms a pair of first walls <NUM>, a pair of second walls <NUM>, and a third wall <NUM> on a frame having a rectangular parallelepiped shape.

Further, the housing <NUM> may be formed by integrally molding a pair of first walls <NUM>, a pair of second walls <NUM>, and a third wall <NUM>.

As shown in <FIG>, the holder <NUM> includes, for example, a tray <NUM>, a holding part <NUM>, and a guide part <NUM>. The tray <NUM> is formed in a rectangular cylindrical or parallelepiped shape which is in contact with the pair of first walls <NUM> and the pair of second walls <NUM>. For example, the tray <NUM> is configured such that a wall portion of the tray <NUM> that forms an upper wall of the tray <NUM> is opposed to the first wall <NUM> and can be opened and closed.

Note that the tray <NUM> may not have the wall portion opposed to the first wall <NUM> forming the upper wall, for example as shown in <FIG>.

The tray <NUM> has a width equal to or slightly larger than the width of the bag <NUM>, between inner surfaces of a pair of walls opposed to the pair of second walls <NUM>.

The tray <NUM> is insertable into the opening on the back side of the housing <NUM> and is removable therefrom, so that the tray <NUM> can be attached to and detached from the housing <NUM>.

The tray <NUM> accommodates the plurality of stacked and folded bags <NUM> held by the holding part <NUM>, and the front side and the back side of the tray <NUM> are open so that the plurality of stacked and folded bags <NUM> can be inserted and taken out.

The holding part <NUM> is provided, for example, in the tray <NUM>.

As shown in <FIG>, the holding part <NUM> includes a shaft <NUM> for supporting the folded portion <NUM> of the plurality of stacked and folded bags <NUM>, a support plate <NUM> for supporting one end of the plurality of stacked and folded bags <NUM>, a hanging part <NUM> for hooking and holding the hung parts <NUM> of the stacked and folded bags <NUM>, and an adjusting member <NUM> for urging the shaft <NUM> in one direction.

The shaft <NUM> is disposed to face the take-out opening <NUM> of the third wall <NUM>. The shaft <NUM> is supported by the tray <NUM>. For example, the shaft <NUM> is supported on the tray <NUM> so as to be movable toward the take-out opening <NUM>. The folded portion <NUM> of the plurality of stacked and folded bags <NUM> is wrapped around the shaft <NUM> and the shaft <NUM> supports the folded portion <NUM> from the inside.

The support plate <NUM> supports a bottom side of the plurality of stacked and folded bags <NUM>. The support plate <NUM> is disposed at the rear opening in a state in which the tray <NUM> is disposed in the housing <NUM> and is disposed below the shaft <NUM>. The support plate <NUM> is formed at a predetermined angle with respect to the main surface of the first wall <NUM> on which the top surface becomes a bottom plate. That is, as shown in <FIG>, the support plate <NUM> supports a plurality of stacked and folded bags <NUM> with the shaft <NUM>, thereby supporting the plurality of stacked and folded bags <NUM> at a predetermined angle with respect to the main surface of the first wall <NUM> serving as a bottom wall.

The hanging part <NUM> holds the hung parts <NUM> of the plurality of stacked and folded bags <NUM>. For example, the hanging part <NUM> is provided on an upper wall of the tray <NUM>. The hanging part <NUM> includes a cylindrical part 53a inserted into the hole 113a of the hung part <NUM>, and a flange 53b having a diameter larger than the inner diameter of the hole 113a.

The hanging part <NUM> holds one end of the plurality of stacked and folded bags <NUM> by inserting the cylindrical part 53a into the hole 113a of the hung part <NUM> of the plurality of stacked and folded bags <NUM> and holding the hung part <NUM> of the stacked and folded bags <NUM> by the innermost layer of the flange 53b.

The hanging part <NUM> may be, for example, a hook inserted into the hole 113a of the hung part <NUM>.

The adjusting member <NUM> is a biasing member that presses the shaft <NUM> in one direction toward the take-out opening <NUM>.

The adjusting member <NUM> presses the shaft <NUM> toward the take-out opening <NUM> to keep the positional relationship between the bag <NUM> positioned in the outermost layer of the plurality of stacked and folded bags <NUM> and the take-out opening <NUM> constant even when the number of remaining bags of the plurality of stacked and folded bags <NUM> is reduced.

The adjusting member <NUM> may include, for example, a coil spring or the like which presses the shaft <NUM> toward the take-out opening <NUM>.

In the holding part <NUM>, the plurality of stacked and folded bags <NUM> are supported on the tray <NUM> by the shaft <NUM>, the support plate <NUM>, and the hanging part <NUM>, and the positions of the bags to the take-out opening <NUM> are adjusted by an adjusting member <NUM>.

The guide part <NUM> is provided on a leading end side in the insertion direction of the tray <NUM> from the shaft <NUM> of the tray <NUM>.

The guide part <NUM> is disposed between the take-out opening <NUM> and the shaft <NUM> when the tray <NUM> is disposed in the housing <NUM>.

The guide part <NUM> is composed of a pair of projections 43a arranged side by side in the width direction of the bag <NUM>. For example, each of the pair of projections 43a extends from the width of the bag <NUM> to the width of the second opening 31b of the take-out opening <NUM>, and when a bag <NUM> is taken out from the take-out opening <NUM>, both ends of the bag <NUM> in the width direction engage and are guided to the second opening 31b of the take-out opening <NUM> by the projections 43a.

Next, an example of the dimensional relationship between the take-out opening <NUM> of the bag storage case <NUM> and the bag <NUM> configured as described above will be described with reference to <FIG>.

As shown in <FIG>, the width (bag width) of the bag <NUM> is assumed to be Fs.

The width of the first opening 31a in the second direction is set to Tc, and the width of the first opening 31a in the first direction is set to Th1.

Further, as shown in <FIG>, the width of the second opening 31b in the second direction is set to Tw, and the width of the second opening 31b in the first direction is set to Th2.

The dimension relation between the take-out opening <NUM> and the bag <NUM> is as follows. <MAT> <MAT> <MAT>.

Further, when the L, M and S-size bag <NUM> is used, the size of the first opening 31a is set to Tc≧<NUM>, and Th1≧ <NUM>.

Also, for example, when the width (bag width) Fs (mm) of the bag <NUM> is set to the variable X, and the width Tw (mm) of the second opening 31b of the take-out opening <NUM> is set to the variable Y, the width Tw of the second opening 31b is determined by the linear function Y = <NUM>. 68x+<NUM> as shown in <FIG>.

Note that the width Tw of the second opening 31b may be a width determined by a linear function or a width that is approximate to a width determined by a linear function.

As a specific example, in the case of an L-size bag <NUM> having a bag width Fs of <NUM>, the width Tw of the second opening 31b is set to <NUM>.

In the case of an M-size bag <NUM> having a width Fs of <NUM>, the width Tw of the second opening 31b is set to <NUM>.

In the case of an S-size bag <NUM> having a bag width Fs of <NUM>, the width Tw of the second opening 31b is set to <NUM>.

In the case of the bags <NUM> other than the L, M and S-sizes, it is set on the basis of the linear function.

For example, in the case of the bag <NUM> having the bag width Fs of <NUM>, the width Tw of the second opening 31b is set to <NUM>, and in the case of the bag <NUM> having the bag width Fs of <NUM>, the width Tw of the second opening 31b is set to <NUM>.

The bag storage case <NUM> configured as described above is arranged in such a manner that a plurality of bag storage cases <NUM> accommodating bags <NUM> having different sizes are arranged in the vertical direction, or arranged in the horizontal direction so that the take-out openings <NUM> face the same direction.

For example, <FIG> and <FIG> show an example in which three bag storage cases <NUM> are stacked in the vertical direction, the bag storage case <NUM> containing the L-size bag <NUM> is placed in the lower stage, the bag storage case <NUM> containing the M-size bag <NUM> is placed in the middle stage, and the bag storage case <NUM> containing S-size bag <NUM> is placed in the upper stage.

Each bag storage case <NUM> is arranged so that the take-out opening <NUM> is directed to the customer side.

For example, the bag storage case <NUM> may be provided in a self-checkout device or a settlement device, or may be installed in a place where a commodity purchased by using a self-checkout device or an settlement device is packaged.

For example, the bag storage case <NUM> is disposed below the customer's line of sight.

According to the bag storage case <NUM> configured as described above, by setting the width Tw of the take-out opening <NUM> to a proportional function of the width Fs of the bag <NUM>, the take-out opening <NUM> can be made to have a suitable width to allow the bags <NUM> to be taken out one by one.

Further, since the width of the second opening 31b of the take-out opening <NUM> can be set to the optimum width according to the width of the bag <NUM>, even when a bag <NUM> having a different bag width is used, the bag <NUM> can be taken out from the take-out opening <NUM>.

In addition, the take-out opening <NUM> has a constant shape irrespective of the width of the bag <NUM> to perform the operation of taking out the bag <NUM> from the take-out opening <NUM>.

In addition, the width Th1 in the first direction of the first opening 31a is set to be larger than the width Th2 in the same direction of the second opening 2b.

Therefore, the take-out opening <NUM> can suitably perform the removal operation of the bag <NUM> regardless of the bag width.

The bag storage case <NUM> is provided with a take-out opening <NUM> at a first inclined part <NUM> of the third wall <NUM>.

Therefore, even when one bag storage case <NUM> is used, even when a plurality of bag storage cases <NUM> are stacked and arranged, the first inclined part <NUM> is positioned on the line of sight when the customer visually recognizes the bag storage case <NUM>.

Therefore, the bag storage case <NUM> can improve the visibility of the take-out opening <NUM>, so that the visibility of the bag <NUM> existing in the take-out opening <NUM> is improved.

In addition, the access to the bag <NUM> of the lower take-out opening <NUM> is improved, and even when the bag storage case <NUM> is stacked, the bag <NUM> can be easily taken out from the take-out opening <NUM>.

As described above, according to the bag storage case <NUM> of the first embodiment, by optimizing the relationship between the size of the take-out opening <NUM> and the width of the bag <NUM>, the bag <NUM> can be suitably taken out from the take-out opening <NUM>.

Incidentally, the bag storage case <NUM> is not limited to the above embodiment.

In the example described above, the third wall <NUM> has the configuration having the first inclined part <NUM> and the second inclined part <NUM>, but is not limited thereto.

For example, as shown in <FIG>, the third wall <NUM> may not have the first inclined part <NUM> and the second inclined part <NUM>, but may be formed in a planar shape orthogonal to the first wall <NUM> and the second wall <NUM>.

Further, as shown in <FIG>, the holder <NUM> may not have the upper wall of the tray <NUM> and the support plate <NUM>.

In the example described above, the plurality of stacked and folded bags <NUM> are held by the holding part <NUM>, and the take-out opening <NUM> is opposed to the folded portion <NUM> of the stacked and folded bags <NUM>, but is not limited to this configuration as described above.

For example, the take-out opening <NUM> may be opposed to a portion other than the folded portion <NUM> of the stacked and folded bags <NUM>, and the holding part <NUM> may be configured to hold a plurality of stacked bags <NUM> without being folded.

According to the bag storage case of at least one embodiment described above, the bag is suitably taken out from the take-out opening by optimizing the relation between the size of the take-out opening and the bag width of the bag.

While certain embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the invention.
