In addition, although the orientation of the container body upper portion changes when the container body upper portion is rotated relative to the container body lower portion, the following description will be made with reference to a state in which the container body upper portion and the container body lower portion are combined and the storage space S is closed, as shown in fig. 1.

[ Structure of embodiment ]

(Overall Structure)

As shown in fig. 1 to 8, a home tissue paper storage container 1 includes: a container body 10 having a taking-out hole 113a for taking out the household tissue paper P therein; an opening/closing lid 2 openably and closably connected to the container body 10 so as to cover the removal hole 113 a; and a button portion 3 provided in the container body 10 for opening and closing the opening and closing lid 2, and a housing space S for housing the household tissue paper P is formed in the household tissue paper housing container 1.

(tissue paper for household)

As the household tissue paper P, for example, a so-called pop-up sheet is used, which is formed by stacking small wet sheets, wet tissues, and the like in an alternately folded state, and pulling out a next wet sheet, wet tissue, and the like when pulling out one wet sheet, wet tissue, and the like. For example, a long wet sheet or wet tissue having a perforation line applied thereto at a constant interval in the longitudinal direction may be wound in a roll shape and cut off along the perforation line to use a roll paper.

(Container main body)

As shown in fig. 1 to 7, the container body 10 is formed in a substantially rectangular parallelepiped shape longer than the X direction and the Z direction in the Y direction as a whole, for example, and the container body 10 is divided into two upper and lower portions at an upper portion than a center portion in the Z direction, and is formed by a container body upper portion 11 constituting an upper side of the container body 10 and a container body lower portion 12 constituting a lower side of the container body 10. The container body upper part 11 and the container body lower part 12 are connected to each other by a connecting part 13 at the rear surface part of the container body 10.

The container body upper portion 11, the container body lower portion 12, and the connecting portion 13 are integrally formed by injection molding (two-color molding) or the like.

As shown in fig. 1 to 7, the container body 10 is formed to have a size of preferably 60mm to 150mm, more preferably 80mm to 100mm, in the X direction, preferably 80mm to 200mm, more preferably 145mm to 165mm, in the Y direction, preferably 30mm to 100mm, more preferably 50mm to 70mm, in the Z direction, as a whole, in a state where the container body upper portion 11 and the container body lower portion 12 are combined and the storage space S inside is closed.

The thickness of each surface is preferably 0.5mm to 3mm, more preferably 1mm to 2 mm.

If the size and thickness are the same, the molding efficiency is high and the strength without problems in practical use can be realized.

(connecting part)

As shown in fig. 3, the tissue paper storage container 1 for home use is formed to be rotatable about a connecting portion 13 connecting an upper portion 11 of a container body and a lower portion 12 of the container body as a fulcrum. As a result, as shown in fig. 4, the storage space S can be exposed to the outside.

When closing the storage space S, the user may rotate the container body upper portion 11 in the opposite direction to the above.

As shown in fig. 3, the connecting portion 13 is formed thinner than the other portions of the household tissue paper storage container 1, so that the connecting portion 13 is easily bent, and the container main body upper portion 11 is easily rotated with respect to the container main body lower portion 12 about the connecting portion 13 as a fulcrum.

Further, although productivity is lowered, the container body upper part 11 and the container body lower part 12 are formed separately, and as a result, they can be rotatably connected by a hinge or the like.

Further, by dividing the container body 10 into two parts, namely, the container body upper part 11 and the container body lower part 12, on the upper part of the Z-direction central part, when the stored household tissue paper P is stored in the storage space S in a state where it is covered with a predetermined package, the possibility of pinching the end seal part of the package when the storage space S is closed can be reduced, and the replacement of the household tissue paper P can be made easier.

The container body 10 may be divided into two parts, i.e., the container body upper part 11 and the container body lower part 12, in the vicinity of the center part in the Z direction.

(Upper part of the container body)

As shown in fig. 2 to 8, the container main body upper portion 11 is formed in a substantially rectangular parallelepiped shape having a substantially rectangular opening portion on the lower surface, for example, a concave portion 112 recessed downward in the Z direction is formed near the center of the top surface portion 111 forming the upper surface, a taking-out portion 113 is provided in the concave portion 112, and the taking-out portion 113 has a taking-out hole 113a for taking out the household tissue paper P in the storage space S in the center. Further, a housing recess 115 for housing the biasing member 114 is formed at the rear end portion, and a button attachment portion 116 to which the button portion 3 is attached is formed at the front end portion.

An annular outer edge portion 117 and an annular inner edge portion 118 provided inside the outer edge portion 117 and protruding downward from the outer edge portion 117 are formed at a lower end portion of the lower surface of the container main body upper portion 11.

A grip 119 for gripping when the storage space S is exposed is formed at a lower end portion of the front surface of the container main body upper portion 11.

(Material of upper part of container body)

The vessel body upper portion 11 is formed of a hard material, which is a hard material. As the hard material, for example, polyethylene, polypropylene, or the like can be used. The hardness is measured in the same manner as described for the elastic material.

Further, a portion formed of an elastic material and a portion formed of a hard material, which will be described later, are preferably formed integrally by injection molding (two-color molding).

(concave part)

As shown in fig. 2, the recess 112 is formed near the center of the top surface 111 in a plan view. In fig. 2, the concave portion 112 is illustrated as a substantially rectangular curved portion reaching the distal end portion of the container main body upper portion 11 in a plan view, but the specific shape of the concave portion 112 is not limited thereto.

The depth of the recess 112 in the Z direction is preferably 5mm to 20mm as viewed from the top surface 111. The size in plan view is not particularly limited as long as the take-out portion 113 can be formed therein, but is preferably 40mm to 80mm in the X direction and 40mm to 120mm in the Y direction.

(taking-out part)

The extraction portion 113 is a portion formed of an elastic material and formed in the vicinity of the central portion of the concave portion 112 in a plan view, a bulging portion 113b bulging in a substantially spherical shape is formed at substantially the center of the extraction portion 113, and an extraction hole 113a is provided in the bulging portion 113 b.

Further, three protruding pieces 113c are provided at the edge of the removal hole 113a so as to protrude from the edge on the front side toward the center of the removal portion 113.

The taking-out section 113 is preferably formed in a film shape having a thickness of 0.5mm to 2mm in the Z direction, for example.

As the elastic material forming the take-out portion 113, for example, a material having elasticity such as a thermoplastic elastomer of silicone rubber, styrene-butadiene, polyester, polyethylene, or polyurethane can be used, and the hardness is preferably 20 to 90. The hardness was measured in accordance with JIS K6253 (type A durometer).

Further, if the hardness of the elastic material is lower than the above value, the elastic material is too soft to be molded, and molding efficiency is deteriorated, which is not preferable.

Further, if the hardness of the elastic material is higher than the above value, the taking-out portion 113 formed with the taking-out hole 113a for taking out the household tissue paper P becomes hard, and an excessive resistance is generated, so that it becomes difficult to take out the sheets one by one, or it becomes difficult to insert a finger into the housing space S at the time of taking out the sheet, which is not preferable from both points of view.

(taking out hole)

The taking-out hole 113a is a hole formed in the center of the taking-out portion 113 in a plan view and connected to the storage space S.

For example, in fig. 2, the extraction hole 113a has a shape in which each side of a triangle protrudes inward in an arc shape, and is formed in a substantially inverted Y shape in which 3 slits intersect at a gravity center point so as to connect each vertex and the gravity center point. In addition, the width of the slit extending in the X direction among the 3 slits is wider than the widths of the other slits.

The number of slits may be larger or smaller than the above, or may be formed in a cross shape by dividing two slits, for example.

The taking-out section 113 is formed of an elastic material around the taking-out hole 113a, and can apply an appropriate resistance to the household tissue paper P, thereby playing a role of holding the next household tissue paper P after the household tissue paper P stored in the storage space S is pulled out. When the household tissue paper P is roll paper, the household tissue paper P can be cut by a perforation line provided for cutting the household tissue paper P.

(Tab)

The protruding piece 113c is a portion that comes into sliding contact with the household tissue paper P pulled out from the taking-out hole 113a, and is provided to apply an appropriate resistance to the household tissue paper P pulled out from the taking-out hole 113 a.

Specifically, when the user opens the opening/closing lid 2 of the home tissue paper storage container 1 to take out the home tissue paper P, the user inserts his/her hand from the front side of the home tissue paper storage container 1 to pull out the home tissue paper P from the take-out hole 113a so that the opening/closing lid 2 in a posture standing on the rear side of the home tissue paper storage container 1 does not interfere with the operation of taking out the home tissue paper P, and therefore the home tissue paper P pulled out from the take-out hole 113a is in sliding contact with the protruding piece 113c of the edge on the near side.

At this time, the projecting piece 113c projecting rearward from the edge on the near side comes into sliding contact with the household tissue P pulled out to the near side from the taking-out hole 113a, and the projecting piece 113c applies an appropriate resistance to the household tissue P, thereby preventing the household tissue P from being excessively pulled out from the taking-out hole 113 a.

That is, the protruding piece 113c protruding rearward from the edge on the near side has the following function: by applying an appropriate frictional force to the household tissue paper P pulled out to the near side from the take-out hole 113a, the next household tissue paper P pulled out of the household tissue paper P used immediately after the pull-out is prevented from being excessively pulled out from the take-out hole 113 a.

Then, the next piece of the household tissue paper P pulled out from the immediately used household tissue paper P is held in the take-out hole 113a in a state where one end portion thereof is pulled out by an appropriate length.

One end of the household tissue paper P held in the removal hole 113a is supported by three projecting pieces including the projecting piece 113c on the front side.

Since the extraction hole 113a for holding one end of the household tissue paper P is provided in the bulge portion 113b of the extraction portion 113, the distal end side of each protruding piece 113c is located higher than the extraction portion 113 which is the base surface around the bulge portion 113 b.

Further, since one end of the household tissue paper P is supported by the protruding piece 113c at a position higher than the periphery and held in the taking-out hole 113a, the household tissue paper P can be easily gripped.

(urging member)

As shown in fig. 2, the urging member 114 is a belt-like member formed of an elastic material. The urging member 114 has one end fixed to the rear of the recess 112 and the other end fixed to an insertion portion 23 (described later) of the opening/closing lid 2, and urges the opening/closing lid 2 in an opening direction in which the opening/closing lid 2 stands, and when the user presses the button portion 3, the opening/closing lid 2 is opened by rotating around a connecting portion with the container main body upper portion 11 at the rear as a rotation axis.

The urging member 114 is formed in a belt shape having a width of preferably 2mm to 30mm, more preferably 8mm to 10mm, and a thickness of preferably 0.5mm to 3mm, more preferably 1mm to 2 mm.

The biasing member 114 is formed in such a size that it can be easily pushed up when the opening/closing lid 2 is opened, and can be easily folded and stored in the storage recess 115 when the opening/closing lid 2 is closed.

By forming the biasing member 114 in an extended state as shown in fig. 2 in a state where no force is applied, as shown in fig. 7, when the opening/closing cover 2 is closed and the biasing member 114 is bent, a force is generated to return to the state shown in fig. 2. This can urge the opening/closing lid 2 to rotate rearward with respect to the container main body upper part 11 about the connecting part 13 between the opening/closing lid 2 and the container main body upper part 11 as a rotation axis.

(storage recess)

As shown in fig. 7, the housing recess 115 is a recess for housing a bent portion of the biasing member 114 when the biasing member 114 is pushed downward when the opening/closing cover 2 is closed.

As shown in fig. 2, the storage recess 115 is formed in the recess 112 so as to be recessed further downward in the Z direction than the recess 112, at the rear of the removal portion 113 and in the vicinity of the front of the biasing member 114.

The shape of the housing recess 115 is not particularly limited, and may be, for example, a substantially rectangular parallelepiped shape longer in the Y direction than in the X direction, provided that there is a space in which the biasing member 114 pushed and bent by the opening/closing lid 2 can be housed when the opening/closing lid 2 is closed.

(push button mounting part)

The button attachment portion 116 is formed of a hard material at the front end of the recess 112, and includes: a main body side fitting portion 1161 formed in a ring shape so as to be convex upward in the Z direction; and a button movable portion 1162 formed to be concave downward in the Z direction so as to surround left and right portions and a front portion of the main body side fitting portion 1161 in a plan view.

(Main body side fitting part)

The main body side fitting portion 1161 has a curved front side and a linear rear side in plan view, for example, and has an inner periphery slightly larger than an outer periphery of a button side fitting portion 32 (described later) formed in the button portion 3. The button portion 3 can be attached to the button attachment portion 116 by inserting the button-side fitting portion 32 from above.

(Movable part of push button)

The button movable portion 1162 is formed to have a downward concave shape so as to surround the left and right portions and the front portion of the main body side fitting portion 1161, and is formed of the same elastic material as the removing portion 113. Thus, when the distal end portion 31a of the button portion 3 inserted into the main body side fitting portion 1161 is pressed from above, the button movable portion 1162 is elastically deformed, and the button portion 3 is inclined downward.

(outer edge part, inner edge part)

As shown in fig. 4 and 5, the outer edge 117 is annular and is formed at the lower end of the container body upper portion 11.

As shown in fig. 4 and 5, the rim portion 118 is formed in an annular shape, is provided inside the outer rim portion 117 in the lower end portion of the container main body upper portion 11, and protrudes downward from the outer rim portion 117, and when the housing space S is closed, the rim portion 118 enters a groove portion 121 of the container main body lower portion 12 described later.

(handle part)

As shown in fig. 1 to 8, for example, the grip portion 119 is formed at the center of the front surface of the container body upper portion 11 so as to protrude from the front surface in an arch shape integrally with the container body upper portion 11, and a gap a capable of being caught by a finger is formed between the grip portion and the front surface. Two locking portions 1191 are provided on an inner surface of the grip portion 119 facing the front surface. When the storage space S is exposed, the grip portion 119 is gripped, and the container body upper portion 11 is rotated about the connecting portion 13 as a fulcrum.

As shown in fig. 7 and 8, the intersection between the front surface of the container body upper portion 11 and the inner surface of the handle portion 119 is formed in an arc shape with rounded corners.

The shape of the grip 119 may be any shape as long as it protrudes from the front surface of the container body upper portion 11 and has a gap a with the front surface, instead of protruding in an arch shape.

In a state where the container body upper portion 11 is engaged with the container body lower portion 12, the handle portion 119 overlaps with an engagement projection 123 (described later) provided on the container body lower portion 12 in the front-rear direction. This makes the engaging projection 123 invisible from the front.

(engaging part)

As shown in fig. 4 to 8, the locking portions 1191 are provided in two at a predetermined interval in the left-right direction on the inner surface of the handle portion 119, and are formed to engage with the engaging projections 123 when the housing space S is closed, so that the closed state is maintained.

The interval between the two locking portions 1191 may be arbitrarily set, but may be larger than the width of a finger of a general user. Specifically, the distance is preferably 5mm to 25mm, more preferably 18mm to 25 mm.

The number of the locking portions 1191 is not limited to two, and may be provided at positions separated from the center portion of the inner surface of the grip portion 119 in the left-right direction to the left and right, and may be, for example, two (four in total) provided on the left and right.

(lower part of container body)

As shown in fig. 4, the container body lower portion 12 is formed in a substantially rectangular parallelepiped shape having a substantially rectangular opening portion on the upper surface, and an annular recessed groove portion 121 is formed at the upper end portion.

Further, a slip prevention part 122 is formed on the bottom of the upper surface of the container main body lower part 12, and the slip prevention part 122 is a slip prevention part when the household tissue paper P stored in the storage space S is taken out from the taking-out hole 113 a.

An engaging projection 123 projecting forward is formed integrally with the container body lower portion 12 in the vicinity of the center of the upper end portion of the front surface of the container body lower portion 12.

(Material of lower part of Container body)

The container body lower part 12 is formed of the same hard material as that used in the container body upper part 11.

(groove part)

As shown in fig. 4, the recessed portion 121 is formed in an annular shape at the upper end portion of the container body lower portion 12, and includes an outer peripheral wall portion 1211 and an inner peripheral wall portion 1212 so that the inner edge portion 118 of the container body upper portion 11 is engaged therewith when the storage space S is closed.

(outer peripheral wall part, inner peripheral wall part)

The outer peripheral wall 1211 is formed as an outer peripheral wall surface of the container main body lower portion 12 and abuts against the outer edge portion 117 of the container main body upper portion 11 when the storage space S is closed.

The inner peripheral wall portion 1212 is formed as an inner peripheral wall surface of the container main body lower portion 12, protrudes upward from the outer peripheral wall portion 1211, and includes, as shown in fig. 4, first guide portions 1212a provided at both end portions in the left-right direction of the rear surface and a plurality of second guide portions 1212b provided in the left-right direction of the rear surface.

The inner edge portion 118 of the container main body upper portion 11 is in sliding contact between the outer peripheral wall portion 1211 and the inner peripheral wall portion 1212, thereby maintaining the sealing property of the storage space S.

(first guide section. second guide section)

The first guide portions 1212a are provided, for example, at both left and right end portions of the rear surface of the container body lower portion 12 so as to extend leftward or rightward, and have a height in the Z direction higher than the outer peripheral wall portion 1211 and the second guide portions 1212 b.

The second guide portions 1212b are formed in a wave shape, and are provided in plural along the left-right direction on the rear surface of the container main body lower portion 12, and have a height in the Z direction higher than the outer peripheral wall portion 1211 but lower than the first guide portions 1212 a.

(non-slip part)

The anti-slip portion 122 is formed of an elastic material surrounded by a hard material at the bottom of the container main body lower portion 12, and has a shape in which, for example, as shown in fig. 4, two straight lines connecting opposite vertices of a rectangle intersect at a center of gravity point, and two corners formed so as to extend in the Y direction out of the corners formed by the two straight lines draw an arc.

In addition, the four ends of the two straight lines are rounded, and as shown in fig. 6, only the elastic material of the rounded portions comes into contact with the mounting surface and functions as a mounting portion 1221.

(engaging projection)

As shown in fig. 4 and 5, the engaging projection 123 is a projection projecting forward integrally with the container body lower portion 12 at a substantially central portion of an upper end portion of the front surface of the container body lower portion 12, and engages with the two locking portions 1191 when the housing space S is closed.

The engaging projection 123 is formed to have a length in the Y direction longer than the sum of the distance between the two locking portions 1191 and the length in the Y direction of each of the two locking portions 1191.

(opening and closing lid)

As shown in fig. 1 to 3, the opening/closing lid 2 is a flat, curved, substantially rectangular member rotatably connected to the rear of the recess 112, and includes an opening/closing lid side locking portion 21 on the front side in a closed state, and an opening/closing lid side sealing ring portion 22 on the lower surface side and an insertion portion 23 into which the force applying member 114 is inserted.

The opening/closing lid 2 is formed so that its shape in plan view when closed is substantially the same as the shape of the recess 112 of the container main body upper portion 11 in plan view except for the portion provided with the push button portion 3, and is formed so as to be fittable into the recess 112 when closed and to be flush with the top surface portion 111.

(Material of opening/closing cover)

As shown in fig. 1 to 3, the entire opening/closing lid 2 is made of the same hard material as that used for the container body 10.

(side stop part of opening/closing cover)

As shown in fig. 2 and 3, the opening/closing cover side locking portion 21 is, for example, a claw-shaped portion protruding forward of the opening/closing cover 2. The opening/closing lid 2 is locked in a closed state by engaging with a button-side locking portion 33 formed in the button portion 3. When the user presses the button portion 3, the engagement between the open/close cover-side locking portion 21 and the button-side locking portion 33 is released, and the open/close cover 2 is opened by the biasing force generated by the biasing member 114.

The shape of the opening/closing cover side locking portion 21 is not limited to the claw shape shown in fig. 2 and 3, and any shape may be used as long as the opening/closing cover 2 is locked in a closed state by being engaged with the button side locking portion 33, and the engagement between the opening/closing cover side locking portion 21 and the button side locking portion 33 is released when the user presses the button 3.

(side sealing ring of opening/closing cover)

As shown in fig. 2, the opening/closing cover side sealing ring portion 22 protrudes downward in a ring shape when the opening/closing cover 2 is closed, and as shown in fig. 7, an inner peripheral side surface thereof is formed at a substantially central portion on the lower surface side so as to contact the outer periphery of the take-out portion 113 formed in the container main body upper portion 11.

(insert part)

As shown in fig. 2, the insertion portion 23 is configured to insert and fix the urging member 114 into the rear end portion of the opening/closing cover 2.

(push button part)

The push button portion 3 has an upper surface portion 31 forming an upper surface, a push button side fitting portion 32 protruding downward from the upper surface portion 31, and a push button side locking portion 33 with which the opening/closing lid side locking portion 21 is engaged, and is formed so that the opening/closing lid 2 is locked in a closed state by inserting the opening/closing lid side locking portion 21 into the push button side locking portion 33, and when a user presses the push button portion 3, the locking of the opening/closing lid side locking portion 21 is released, and the opening/closing lid 2 is opened.

The button portion 3 is formed as a separate member independently of a hard material used for the container main body 10, and then fixed by the button attachment portion 116.

Further, as described above, the tissue paper storage container 1 for home use is preferably integrally formed by injection molding (two-color molding) in its entirety except for the opening/closing lid 2 and the push button portion 3.

(Upper surface part)

As shown in fig. 1, 7, and 8, the upper surface portion 31 is a portion forming the upper surface of the button portion 3, and is formed, for example, in a shape having a straight rear side and an arc front side in a plan view, substantially the same shape as a shape in a plan view in the vicinity of the front end portion of the recess portion 112 except for the vicinity of the distal end portion 31a, and the distal end portion 31a is formed to protrude forward from the recess portion 112.

The size of the upper surface portion 31 is determined according to the size of the portion of the concave portion 112 not covered with the opening/closing cover 2, but it is preferable that the longest portion in the X direction has a length of 10mm to 30mm and the longest portion in the Y direction has a length of 30mm to 100 mm.

A gap b is formed between the distal end portion 31a of the upper surface portion 31 and the container body upper portion 11, and the distal end portion 31a and the proximal end portion 31b are formed to be inclined downward at different angles with respect to the upper surface (parallel) of the container body upper portion 11.

At this time, the inclination angle of the distal end portion 31a is formed larger than that of the proximal end portion 31 b. Specifically, the inclination angle of the proximal portion 31b is preferably 6 to 8 degrees, and the inclination angle of the distal portion 31a is preferably 8 to 10 degrees.

The base end 31b of the button may be parallel to the container body upper portion 11, and only the distal end 31a may be inclined downward, or may be inclined at the same angle from the base end 31b to the distal end 31 a.

(push button side fitting part)

The button-side fitting portion 32 is formed in a ring shape in which the front side is curved and the rear side is linear in a bottom view, for example, so as to protrude downward from the upper surface portion 31, and the outer periphery thereof is slightly smaller than the inner periphery of the above-described main body-side fitting portion 1161, and the button portion 3 can be attached to the button attachment portion 116 by being inserted into the main body-side fitting portion 1161 from above.

Further, the inner periphery may be the same as or slightly larger than the outer periphery of the main body side fitting portion 1161, and the button portion 3 may be attached to the button attachment portion 116 by inserting the main body side fitting portion 1161 from below.

(push button side stop part)

The button-side locking portion 33 is a hole formed at the rear of the button portion 3, and is formed to lock the opening/closing cover 2 in a closed state by inserting the opening/closing cover-side locking portion 21 formed in the opening/closing cover 2 into the inside to engage therewith, and when the user presses the button portion 3, the opening/closing cover-side locking portion 21 is inserted and disengaged therefrom, and the opening/closing cover 2 is opened by the urging force generated by the urging member 114.

The shape of the button-side locking portion 33 is arbitrary as long as the engagement between the button-side locking portion 33 and the opening/closing cover-side locking portion 21 is released when the user presses the button 3 by locking the opening/closing cover 2 in a closed state, and is not limited to the hole shown in the drawing, and may be, for example, a claw portion that engages with the opening/closing cover-side locking portion 21.

[ Effect of the embodiment ]

Hereinafter, the main effects obtained by the present embodiment will be described.

(handle part)

According to the present embodiment, since the handle portion 119 is provided in the container main body upper portion 11 of the household tissue paper storage container 1 and the inner peripheral side of the handle portion 119 is formed into a curved surface by the arc-shaped processing, the handle portion 119 is easily expanded outward as compared with the case where the inner peripheral side is an acute angle, and the engagement between the locking portion 1191 and the engaging projection 123 is easily released, so that the storage space S can be easily exposed.

In particular, since the plurality of locking portions 1191 are provided at positions laterally spaced apart from the center portion in the lateral direction of the inner surface of the grip portion 119, when a finger is inserted near the center of the grip portion 119, the locking portions 1191 do not become an obstacle, and the engagement between the container body upper portion 11 and the container body lower portion 12 can be released more easily to expose the storage space S.

Further, since the locking portion 1191 is provided in the handle portion 119, the user can easily release the engagement between the container body upper portion 11 and the container body lower portion 12 by hooking the gap a between the front surface of the container body upper portion 11 and the handle portion 119 with his or her fingers to expose the storage space S.

Further, since the two locking portions 1191 are formed on the inner surface of the handle portion 119 and the interval between the two locking portions 1191 is set to be wider than the width of the finger, the finger can easily enter between the two locking portions 1191 when the container main body upper portion 11 is rotated, the container main body upper portion 11 can be easily rotated, and the storage space S can be easily exposed.

Since the length of the engaging protrusion 123 in the left-right direction is longer than a length obtained by adding the length of the two locking portions 1191 in the left-right direction to the distance between the two locking portions 1191, and the two locking portions 1191 are engaged with one engaging protrusion 123, the strength is improved as compared with a case where the engaging protrusion 123 is provided independently for each locking portion 1191, and the locking portions 1191 can be engaged more stably.

(Overall Structure)

The container body 10 is composed of a container body upper part 11 and a container body lower part 12, and the container body upper part 11 and the container body lower part 12 are connected to each other at the rear surface by a connecting part 13, so that the container body upper part 11 is turned with the rear end part as a fulcrum to expose the storage space S in a state where the household tissue paper storage container 1 is placed on the placement surface, and the household tissue paper P can be replaced.

Therefore, when the household tissue paper P is replaced, the replacement work can be performed more easily in a state where the household tissue paper container 1 is placed on the placement surface.

In a state where the container body upper portion 11 and the container body lower portion 12 are engaged with each other, the handle portion 119 and the engaging projection 123 provided on the container body lower portion 12 overlap each other in the front-rear direction. This makes the engaging projection 123 invisible from the front, and the appearance is good.

Further, the container body upper portion 11, the container body lower portion 12, and the connecting portion 13 are integrally formed by injection molding (two-color molding) or the like, and therefore, the container is excellent in manufacturing efficiency of the household tissue paper storage container 1.

(taking out hole)

Since the next piece of household tissue paper P pulled out from the take-out hole 113a is held in the take-out hole 113a with one end thereof pulled out by an appropriate length, the household tissue paper P held in the take-out hole 113a does not become an obstacle when the open-close cover 2 is closed.

Further, since the household tissue paper P held in the take-out hole 113a is not sandwiched by the opening/closing cover 2, there is no problem that the wet household tissue paper P (wet tissue paper or the like) is protruded to the outside of the container body 10 and dried by being sandwiched by the opening/closing cover 2.

In the case of the home tissue paper storage container 1 provided with the take-out hole 113a, the home tissue paper P can be appropriately pulled out for use, and one end portion of the next piece of home tissue paper P pulled out from the home tissue paper P used immediately after pulling out can be held in the take-out hole 113a so as not to hinder the closing of the opening/closing lid 2.

Further, by holding the household tissue paper P pulled out by an appropriate length in the take-out hole 113a, the household tissue paper P stored in the storage space S can be pulled out and used repeatedly as appropriate.

Further, the width of only the slit extending in the X direction out of the three slits of the taking-out hole 113a is wider than the other slits, and therefore the supporting portions of one end of the household tissue paper P held in the taking-out hole 113a by the two projecting pieces 113c other than the near side are dispersed, and one end of the household tissue paper P can be supported by the taking-out hole 113a more stably.

Further, the two other slits extending to the front side are relatively narrow in width, and thus, when the household tissue paper P is taken out, one end portion can be prevented from entering the slit.

(push button parts, etc.)

According to the home tissue paper storage container 1 of the present embodiment, the push button portion 3 is attached to the main body side fitting portion 1161 surrounded by the push button movable portion 1162 protruding downward. Thus, when the user presses the upper surface portion 31 of the button portion 3 from above in a state where the opening/closing lid 2 is closed, the button movable portion 1162 is deformed downward regardless of the pressing position, and the button portion 3 sinks downward.

At this time, since the opening/closing lid side locking portion 21 of the opening/closing lid 2 is inserted into the button side locking portion 33 of the push button portion 3, when the push button portion 3 is lowered downward, the opening/closing lid 2 is pushed downward in accordance with the depression, but the opening/closing lid 2 is biased upward by the biasing member 114, and the more the opening/closing lid 2 is lowered downward, the stronger the biasing force becomes.

Therefore, when the push button portion 3 is pushed in to some extent, the opening/closing lid 2 sinks accordingly, and the upward urging force against the opening/closing lid 2 becomes strong, but since the opening/closing lid 2 and the push button portion 3 are engaged only by the opening/closing lid side engaging portion 21 and the push button side engaging portion 33, when the urging force against the opening/closing lid 2 becomes strong, the engagement is released, and the opening/closing lid 2 is opened.

Therefore, according to the present embodiment, the opening/closing lid 2 can be easily opened regardless of the portion of the upper surface of the push button portion 3.

Further, the container body upper portion 11 includes the button mounting portion 116 having the body side fitting portion 1161, and thus the button portion 3 can be easily and stably fixed.

In the push button portion 3, since the tip end portion 31a of the upper surface portion 31 is formed to have a larger inclination angle than the base end portion 31b, it is difficult to insert a finger into the gap b between the push button portion 3 and the container main body upper portion 11, and it is possible to prevent the push button portion 3 from being erroneously gripped and rotated as the handle portion 119 when the household tissue paper P is replaced.

(urging member)

Further, according to the household tissue paper storage container 1 of the present embodiment, the opening/closing lid 2 can be biased in the opening direction only by providing the biasing member 114 with an elastic material in the container main body upper portion 11.

On the other hand, for example, in the case of a structure in which a spring-like urging member standing upward is provided and the urging member is connected to the opening/closing cover 2, the spring-like urging member is repeatedly bent and extended every time the opening/closing cover 2 is opened or closed, and therefore, such a spring-like portion is easily deteriorated and the urging force to the opening/closing cover 2 is easily reduced at an early stage. If the urging force acting on the opening/closing cover 2 is weakened to some extent, the opening/closing cover cannot be opened by a single push.

According to the present embodiment, since the urging member 114 formed of an elastic material is configured to generate an urging force with respect to the opening/closing cover 2 by being pressed by the opening/closing cover 2, the amount of deformation of the portion formed of an elastic material is small, and the portion is not easily deteriorated, so that the urging force with respect to the opening/closing cover 2 is not easily weakened.

Further, by providing the housing recess 115 in the recess 112, it is possible to prevent the pressure applied to the contact portion of the biasing member 114 with the recess 112 from becoming too large, and to reduce the possibility of breakage of the biasing member 114.

Further, since the urging member 114 is formed on the rear side of the container body 10 near the fulcrum of the rotation of the opening/closing cover 2, the urging force against the opening/closing cover 2 is increased, and the opening/closing cover 2 is easily opened.

(closure of the Container)

When the housing space S is closed, the inner edge portion 118 of the upper container body portion 11 is fitted into the groove portion 121 of the lower container body portion 12, so that the housing space S is not easily exposed even when pressure is applied to the household tissue paper housing container 1 in the X direction and the Y direction, and the housing space S can be kept closed, thereby providing a good sealing property.

In addition, when the storage space S is closed, the first guide portion 1212a and the second guide portion 1212b provided in the container body lower portion 12 guide the inner edge portion 118 of the container body upper portion 11 to the groove portion 121 while keeping the inner edge portion in contact with the guide portions, thereby more reliably closing the storage space S.

In particular, since the two first guide portions 1212a are higher than the second guide portions 1212b in the Z direction, even if the container body upper portion 11 is slightly twisted with respect to the container body lower portion 12 when the storage space S is closed, the track adjustment can be performed by being guided by the higher first guide portions 1212a, and therefore, the reliability of closing the storage space S can be further improved.

In addition, the two first guide portions 1212a are provided at both left and right end portions of the rear surface so as to extend to the left or right, respectively, whereby the above-described effects can be further enhanced.

Further, by providing the second guide portions 1212b in a wave shape, the contact resistance can be reduced as compared with the case where the second guide portions 1212b are provided over the entire left-right direction, and the opening and closing operation can be performed more smoothly.

(other structures)

Further, since the slip prevention portion 122 is provided on the upper surface of the lower portion 12 of the container body, when the household tissue paper P is taken out from the taking-out hole 113a, the household tissue paper P in the housing space S is less likely to move and break, and the household tissue paper P can be taken out stably.

Further, a part forming the slip prevention portion 122 comes into contact with the mounting surface and functions as the mounting portion 1221, whereby stability of the home tissue paper storage container 1 when mounted on the mounting surface can be improved.

Further, when the opening/closing cover 2 is closed, the opening/closing cover side sealing ring portion 22 comes into contact with the outer periphery of the take-out portion 113, whereby the airtightness of the storage space S can be improved.

[ modified examples ]

A modification of the above embodiment will be described below.

(handle part)

The handle portion 119 may be integrally formed with the other portion of the container main body upper portion 11, or may be formed separately and attached.

(engaging projection)

The number of the engaging projections 123 is not necessarily one, and two engaging portions 1191 may be provided.

(guide part)

The guide portion may be constituted by only the first guide portion 1212a or only the second guide portion 1212 b.

The first guide portion 1212a may not be extended to the left or right.

The second guide portions 1212b may not have a wave shape but may be provided at the same height in the left-right direction.

(push button part)

The button portion 3 is only required to be provided in the container main body upper portion 11 so as to be vertically movable by the button movable portion 1162, and is not necessarily required to be attached by the button attachment portion 116. For example, after the elastic member is provided as the button moving portion 1162A over the entire lower surface of the button portion 3, the button portion 3 may be directly attached to the button moving portion 1162A by a method such as adhesion.

(connecting part)

In the above description, the case where the connecting portion 13 is formed only at one place near the center portion in the left-right direction of the home tissue paper storage container 1 has been described, but the configuration of the connecting portion 13 is not limited to this.

For example, the connecting portions 13A, 13A formed on the left and right sides of the home tissue paper storage container 1A may be used. In this case, when the storage space SA is exposed, the connecting portion 13A is not easily twisted, so that the stability is improved, and the work of reclosing the storage container 1A is easily performed.

Further, a connecting portion 13B covering the entire rear surface side of the home tissue paper storage container 1B may be used. In this case, in a state where the storage space S is closed, the entire rear surface side of the contact portion between the container body upper portion 11 and the container body lower portion 12 of the home tissue paper storage container 1B is covered, and therefore, the airtightness of the storage space S can be further improved.

Further, the detailed structure of the home tissue paper storage container 1 can be appropriately modified within a range not departing from the gist of the present invention.
