Summary of the Invention

Problems to be Solved by the Invention

[0004] In the container 1 described in Patent Document 1, as shown in FIG. 16, the nozzle portion 3 is inclined upward to the left. Therefore, in FIG. 16, a portion of the container body 2 located to the left of the left side of the base end of the nozzle portion 3 (to the left of the straight line DL shown by the dotted line in FIG. 16) is curved upward and to the right. Therefore, the volume of the container body 2 becomes smaller, and in order to store a liquid having a certain predetermined specified capacity, the dimensions of the container body 2 are considered to become larger, and the size of the container 1 becomes larger. When the size of the container 1 is large, the space utilization efficiency deteriorates during storage and the like, and the usability for the user deteriorates. Here, the specified capacity is the capacity of the liquid injected into the container body 2 as a product using the container body 2.

[0005] In addition, when the user sprays the liquid contained in the container body 2, it is considered that the user will hold the container body 2 by gripping the handle portion 7 of the container body 2. In the container 1 described in Patent Document 1, since the handle portion 7 is relatively thin, it is considered difficult for the user to firmly grip the handle portion 7. Particularly when the container body 2 contains liquid, the weight of the container body 2 including the liquid becomes heavy, so the handle portion 7 that is difficult to firmly grip places a large burden on the user's hand, wrist, etc., and is considered to be inconvenient to use.

[0006] The present invention has been made in view of the above circumstances, and one of its objects is to improve the convenience for the user.

Means for Solving the Problems

[0007] To achieve the above object, the liquid container according to the present invention includes: a bottom portion that includes an accommodation space for accommodating liquid therein and a body portion that extends upward from the outer edge of the bottom portion, a hollow mouth portion provided at the upper portion of the body portion, which connects the outside of the bottom portion and the body portion to the accommodation space, a grip portion provided on one side portion of the body portion and gripped by the user, a portion including irregularities on the opening surface portion of the grip portion that forms an opening between the grip portion and the body portion, and a finger hook portion that contacts the four fingers of the user who grips the grip portion, the Above the body and an auxiliary support portion provided at a position where at least a part thereof overlaps with the opening when viewed from above and protruding upward. The grip portion is configured symmetrically in the front-rear direction with respect to the center plane, a virtual line passing through the upper end and the lower end of the finger hook portion on the center plane, and provided along a grip axis inclined upward and outward, the grip axis is inclined 5 degrees to 7 degrees with respect to the vertical axis perpendicular to the placement surface when the bottom portion is placed on a flat placement surface, When viewed from above, the entire mouth portion is provided at a position inward of the outer edge of the bottom portion and does not overlap with the opening. The auxiliary support portion is provided with a recess for hanging a finger on a portion facing the mouth portion.

Mode for Carrying Out the Invention

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The same reference numerals are given to the same elements throughout the drawings.

[0015] (Configuration of the liquid container 100 according to an embodiment) The liquid container 100 according to an embodiment of the present invention is a container in which a liquid is stored. The liquid stored in the liquid container 100 may be an appropriate one, for example, agricultural chemicals for gardening and agriculture, cleaning agents for removing various stains, and oil for machines. Further, the liquid stored in the liquid container 100 may be an edible liquid such as drinking water, soft drink, fruit juice, syrup, and oil.

[0016] As shown in FIGS. 1 to 4, the liquid container 100 includes a container body 101 and an outer lid 102. As shown in FIG. 4, the liquid container 100 further includes an inner lid 103.

[0017] Here, FIG. 1 is a front view of the liquid container 100. FIGS. 2 and 3 are perspective views of the liquid container 100 seen from the first direction and the second direction, respectively. FIG. 4 is a front view of the liquid container 100 disassembled.

[0018] The container body 101 has an accommodation space for accommodating a liquid formed therein. The container body 101 includes a bottom portion 104, a body portion 105, a grip portion 106, a thumb contact portion 107, a mouth portion 108, an auxiliary support portion 109, and an upper portion 110, and is integrally formed of, for example, resin. The wall thickness of the container body 101 is, for example, about 1 mm (millimeter).

[0019] Note that the material and wall thickness of the container body 101 may be appropriate according to the chemical properties of the liquid, the strength to hold the liquid, etc., and the material may be other than resin (for example, metal).

[0020] The bottom portion 104 is a part that forms the bottom of the container body 101 and includes a portion that contacts the placement surface MP when the container body 101 is placed on a flat placement surface MP. By providing the bottom portion 104, the bottom portion 104 can be brought into contact with the placement surface MP, and the liquid container 100 can be stably placed on the placement surface MP.

[0021] The bottom portion 104 may be, for example, a plate shape with a flat lower surface, but a bottom-raising structure is desirable. The bottom-raising structure is a structure in which a part of the bottom portion 104 is formed substantially flush and the remaining part protrudes slightly into the interior of the accommodation space.

[0022] As an example of the bottom portion 104 with a bottom-raising structure, a structure can be cited in which a thin strip-shaped lower surface portion along the outer edge of the bottom portion 104 is formed substantially flush, and the portion surrounded by the lower surface portion protrudes slightly into the interior of the accommodation space. In this example, when the container body 101 is placed on a flat placement surface MP, the thin strip-shaped lower surface portion contacts the placement surface MP.

[0023] As another example of the bottom portion 104 with a bottom-raising structure, a structure can be cited in which a plurality of small protrusions protruding downward are provided on the lower surface of a substantially flat plate. In this case, the plurality of small protrusions are preferably provided such that the tops of their lower ends are located on substantially the same plane. In this example, when the container body 101 is placed on a flat placement surface MP, the tops of the lower ends of the plurality of small protrusions contact the placement surface MP.

[0024] Generally, the bottom 104 may bend and protrude outward due to the weight of the liquid or manufacturing errors. In the case of a bottom 104 in the form of a flat plate with a flat lower surface, the stability when the container body 101 is placed on a flat surface may deteriorate. If a bottom-lifting structure is adopted, even when the bottom 104 bends and protrudes outward, the deformation of the outer edge is usually small, so the stability when the container body 101 is placed on a flat surface can be improved. Thereby, it becomes possible to improve the convenience for the user.

[0025] Hereinafter, a state in which the liquid container 100 is placed on a generally horizontal placement surface MP in contact with the bottom 104 is referred to as the "upright state" of the liquid container 100, and "upward" and "downward" are respectively defined along the vertical direction in the upright state. Further, in the container body 101 in the upright state, the direction in which the grip portion 106 (details will be described later) is provided is defined as the "right side", and the opposite direction is defined as the "left side". Furthermore, "front" is defined such that when the liquid container 100 in the upright state is viewed from this direction, the "right side" and the "left side" are the right direction and the left direction, respectively. "Rear" is the opposite direction of "front". The liquid container 100 according to the present embodiment is configured to be generally symmetric with respect to the central plane in the front-rear direction.

[0026] Note that the terms of upward, downward, right side, left side, front, and rear defined here are adopted for the sake of facilitating the explanation, and are not intended to limit the present invention.

[0027] The body portion 105 extends upward from the outer edge of the bottom 104 and constitutes the side portion of the container body 101 except for the grip portion 106. The side portion of the container body 101 refers to the front portion located in front of the container body 101, the rear portion located behind the container body 101, the left side portion located on the left side of the container body 101, and the right side portion located on the right side of the container body 101.

[0028] The grip portion 106 is a portion to be gripped by the user and has a hollow cylindrical shape. The grip portion 106 is provided on the right side portion of the container body 101. In the vertical direction, the grip portion 106 is provided slightly below the center of the container body 101.

[0029] The grip portion 106 includes a finger-hooking portion 111 on a proximal surface which is a surface close to the body portion 105. The finger-hooking portion 111 is a portion where the four fingers (index finger, middle finger, ring finger, little finger) of the user who grips the grip portion 106 come into contact.

[0030] The finger-hooking portion 111 includes irregularities. The irregularities of the finger-hooking portion 111 are composed of a plurality of small recesses having a substantially spherical shape. Note that the irregularities of the finger-hooking portion 111 may be a plurality of grooves, ridges, protrusions, etc.

[0031] In the present embodiment, an insertion hole 112 penetrating the container body 101 in the front-rear direction is formed. The insertion hole 112 has a narrow substantially triangular shape with a narrowing left-right width downward as shown in FIG. 1 when viewed from the front, and the corners are rounded. The grip portion 106 is configured to the right of the insertion hole 112. The user can grip the grip portion 106 by bringing the four fingers inserted into the insertion hole 112 into contact with the finger-hooking portion 111.

[0032] Here, the grip portion 106 has a cylindrical shape extending along a grip axis GL inclined upward and outward. Being inclined upward and outward means being inclined outward from the container body 101 as it goes upward. The outside of the container body 101 means a direction away from the vertical central axis C passing through the center of the bottom portion 104 in the upright state.

[0033] The grip axis GL is a virtual axis located at the front-rear center of the container body 101, and is a virtual axis connecting the upper end and the lower end of a portion where the index finger and the little finger come into contact when the user grips among the proximal surfaces of the grip portion 106 (see FIG. 10). When the user grips the grip portion 106, the grip axis GL is substantially parallel to the inner surfaces of the four fingers.

[0034] The inclination angle θ of the grip axis GL with respect to the central axis C may be determined as appropriate, for example, it is 5 degrees to 7 degrees.

[0035] The shape and dimensions of the grip portion 106 may be appropriately determined according to the size of an average person's hand. The grip portion 106 according to the present embodiment is characterized by a cross-sectional shape perpendicular to the grip axis GL, and the details thereof will be described later.

[0036] The thumb contact portion 107 is a part for a user who holds the grip portion 106 to bring the thumb into contact. The thumb contact portion 107 is provided above the grip portion 106 on the outer right surface of the right side portion of the container body 101.

[0037] The thumb contact portion 107 includes irregularities. The irregularities of the thumb contact portion 107 are constituted by a plurality of ridges arranged in the vertical direction. Each of the ridges is a low protrusion extending in the front-rear direction. Note that the irregularities of the thumb contact portion 107 may be constituted by arranging a plurality of grooves extending in the front-rear direction vertically, or may be constituted by a plurality of protrusions or a plurality of small recesses having a substantially spherical shape.

[0038] The mouth portion 108 is a hollow cylindrical part that connects the outside of the container body 101 and the accommodation space inside thereof, and is provided at the upper left of the container body 101. The opening OP formed at the upper end of the mouth portion 108 is provided in a plane substantially perpendicular to the central axis C. That is, the opening OP is substantially parallel to the flat mounting surface MP on which the bottom portion 104 is placed in the upright state.

[0039] The mouth portion 108 is generally cylindrical and includes an inner lid attachment portion 113, a male screw portion 114, and an annular groove portion 115 on the outer surface (see FIG. 4).

[0040] The inner lid attachment portion 113 is a part to which an inner lid 103 to be described later is attached, and is generally cylindrical.

[0041] The male screw portion 114 is a part connected to the lower end of the inner lid attachment portion 113, and is provided with a male screw that fits with the outer lid 102 by screw action.

[0042] The annular groove portion 115 is a portion that forms a groove provided along the circumferential direction below the male screw portion 114. The outer diameter of the annular groove portion 115 is the same as or smaller than the bottom of the male screw portion 114.

[0043] The auxiliary support portion 109 is provided near the upper part and the right side portion of the container body 101, and is a portion protruding upward. The auxiliary support portion 109 includes, on its outer surface portion, a concave portion 116 whose lower left end is recessed toward the right, and includes, inside, a space that forms part of the accommodation space. By hanging the fingers of the hand opposite to the hand that holds the grip portion 106 in the concave portion 116, the user can easily hold the container body 101 containing liquid.

[0044] The upper end of the auxiliary support portion 109 is at the same vertical position as the upper surface of the outer lid 102. Also, it is desirable that the upper end of the auxiliary support portion 109 is flush with the upper surface of the outer lid 102. Thereby, when the liquid container 100 is boxed and transported, etc., the liquid containers 100 can be stacked stably in the vertical direction.

[0045] The upper portion 110 is a portion that connects between the upper ends of the front and rear portions of the body portion 105 between the mouth portion 108 and the auxiliary support portion 109.

[0046] The outer lid 102 is a member that covers at least the upper end of the mouth portion 108. The outer lid 102 is integrally formed of, for example, resin. The wall thickness of the outer lid 102 is, for example, about 2 mm (millimeters). Note that the material and wall thickness of the outer lid 102 may be appropriate ones according to the chemical properties of the liquid, the required strength, etc., and the material may be other than resin (for example, metal).

[0047] As shown in FIG. 5, the outer lid 102 includes a cap 117, a ring 118, and a plurality of connecting portions 119.

[0048] The cap 117 is generally cylindrical with a downwardly open cylindrical hollow, and includes an internal thread FS on its inner peripheral surface that engages with the external thread portion 114 by screwing action. The internal thread FS of the cap 117 is constituted by a groove provided spirally upward from near the lower end. By including such an internal thread FS, the cap 117 is detachably attached to the mouth portion 108.

[0049] The ring 118 is an annular part disposed below the cap 117 and is disposed so as to surround the annular groove portion 115. The ring 118 includes a plurality of locking claws 120 along the inner circumferential direction. Each of the locking claws 120 is provided on the inner surface of the ring 118 and is a protrusion protruding toward the center of the ring 118. The inner surface of the locking claw 120 (that is, the surface facing the center of the ring 118) is inclined so as to gradually protrude more toward the center of the ring 118 as it goes upward.

[0050] The inner diameter of the ring 118 excluding the locking claws 120 is larger than the nominal diameter of the external thread portion 114. Also, the inner diameter of the plurality of locking claws 120 (that is, the diameter of the circle connecting the tips of the locking claws 120 as viewed from above) is slightly smaller than the root diameter of the external thread portion 114.

[0051] With such locking claws 120, as will be described in detail later, the ring 118 can be positioned in the annular groove portion 115. Also, when the ring 118 is positioned in the annular groove portion 115, the upper ends of the locking claws 120 are locked to the lower end of the external thread portion 114, making it difficult to remove the ring 118 from the annular groove portion 115.

[0052] Note that the outer diameter of the ring 118 may be of an appropriate size, for example, a size such that the outer peripheral surfaces of the ring 118 and the cap 117 are flush.

[0053] The plurality of connecting parts 119 are the parts that connect the lower end of the cap 117 and the upper end of the ring 118. Each of the plurality of connecting parts 119 has a strength such that it will not be cut when the outer lid 102 is attached to the male screw part 114. Also, each of the plurality of connecting parts 119 has a strength such that it will be cut when the cap 117 is removed, and the cap 117 and the ring 118 can be separated.

[0054] The middle lid 103 is a lid that is fitted onto the upper end of the mouth part 108. The middle lid 103 is integrally formed of, for example, resin. The wall thickness of the middle lid 103 is, for example, about 1 mm (millimeter). Note that the material and wall thickness of the middle lid 103 may be appropriate ones according to the chemical properties of the liquid, the required strength, etc., and the material may be other than resin (for example, metal).

[0055] As shown in FIG. 6, the middle lid 103 includes a disk-shaped spraying surface part 121 and a fitting part 122 that extends downward from the outer edge of the spraying surface part 121.

[0056] The spraying surface part 121 is a part that generally covers the flat spraying surface formed at the upper end of the mouth part 108, and includes a plurality of spraying holes 123 that penetrate in the thickness direction. Through the plurality of spraying holes 123, the hollow inside of the mouth part 108 is connected to the outside. The spraying surface part 121 according to the present embodiment is flat plate-shaped and is provided such that its lower surface generally coincides with the spraying surface, but may be changed to a shape other than flat plate-shaped, for example, gently curved so as to protrude upward.

[0057] Note that a plurality of small protrusions P are provided at positions corresponding to each of the plurality of spraying holes 123 on the upper outer surface of the outer lid 102, whereby the user can know from the appearance of the outer lid 102 that the spraying holes 123 are provided inside.

[0058] The fitting part 122 is a part that is fitted into the middle lid attachment part 113. The outer diameter of the fitting part 122 is smaller than the valley diameter of the male screw part 114. The fitting part 122 fits with a strength such that the middle lid 103 does not easily come off from the middle lid attachment part 113. Note that the fitting part 122 and the middle lid attachment part 113 may include a locking structure for locking with each other so that the middle lid 103 does not easily come off from the middle lid attachment part 113.

[0059] So far, the structure of the liquid container 100 according to an embodiment of the present invention has been described. Hereinafter, a method for assembling the liquid container 100 according to the present embodiment will be described.

[0060] (Method for assembling the liquid container 100 according to an embodiment) The container body 101, the outer lid 102, and the middle lid 103 are prepared. A liquid of a specified capacity is injected into the container body 101 from the opening OP of the mouth part 108. Thereby, a liquid of a specified capacity is stored in the storage space of the container body 101.

[0061] Here, the "specified capacity" is the capacity of the liquid injected into the container body 101 as a product using the container body 101. In other words, the specified capacity is the capacity of the liquid injected into the container body 101 at the time of shipment of the product.

[0062] For example, when the liquid container 100 is adopted as a container for selling a liquid, a liquid container 100 having a full filling capacity greater than a predetermined specified capacity is selected.

[0063] The "full filling capacity" is the maximum amount of liquid that can be injected into the storage space from the mouth part 108 in the upright state. In the case of the liquid container 100 according to the present embodiment, when a liquid is injected from the mouth part 108, air does not escape in part or all of the space inside the auxiliary support part 109 and the part or all is not filled with the liquid. Therefore, the full filling capacity of the liquid container 100 according to the present embodiment is the volume of the storage space of the container body 101 excluding the part or all of the space inside the auxiliary support part 109.

[0064] The specified capacity is generally in the range of 60% to 100% of the full filling capacity. That is, for example, in the case of the liquid container 100 including the container body 101 with a full filling capacity of 5 liters, the specified capacity is about 3 liters to 5 liters.

[0065] The middle lid 103 is fitted into the middle lid mounting portion 113. Thereby, the middle lid 103 is attached to the container body 101 so as not to be easily detached from the container body 101.

[0066] Subsequently, the outer lid 102 is screwed onto the male screw portion 114 of the container body 101 by rotating the mouth portion 108 to which the middle lid 103 is attached in a predetermined attachment direction (for example, clockwise).

[0067] As described above, the inner diameters of the plurality of locking claws 120 are slightly smaller than the valley diameter of the male screw portion 114. Therefore, when the outer lid 102 is screwed onto the male screw portion 114, the locking claws 120 come into contact with the male screw portion 114. However, the inner surface of the locking claw 120 is inclined as described above. Therefore, when the outer lid 102 is screwed onto the male screw portion 114, the force received by the locking claw 120 from the male screw portion 114 is relatively small. Also, the ring 118 has elasticity that can be deformed so that its diameter increases when receiving the force from the male screw portion 114.

[0068] Thereby, when the outer lid 102 is screwed onto the male screw portion 114, the plurality of connecting portions 119 are not cut and can move downward beyond the thread of the male screw portion 114.

[0069] The outer lid 102 is screwed until the upper end of the ring 118 is positioned below the lower end of the male screw portion 114, and the ring 118 is positioned in the annular groove portion 115. Thereby, the outer lid 102 is attached to the container body 101 in a state where the ring 118 and the cap 117 are connected by the plurality of connecting portions 119. The liquid container 100 containing the specified capacity of liquid is completed.

[0070] So far, the assembling method of the liquid container 100 according to an embodiment of the present invention has been described. From here, the usage method of the liquid container 100 according to the present embodiment will be described.

[0071] (Usage method of the liquid container 100 according to an embodiment) The user holds the cap 117 and rotates the cap 117 in the removal direction (for example, counterclockwise) opposite to the attachment direction. As a result, the cap 117 moves upward.

[0072] When the upper end of the ring 118 is positioned at the lower end of the male screw portion 114 due to the movement of the cap 117, since the inner diameters of the plurality of locking claws 120 are slightly smaller than the valley diameter of the male screw portion 114 as described above, the upper ends of the plurality of locking claws 120 come into contact with the lower end of the male screw portion 114. Therefore, the ring 118 cannot move upward. When the cap 117 is further rotated in the removal direction in this state, the plurality of connecting portions 119 are cut. As a result, the cap 117 is separated from the ring 118.

[0073] When the cap 117 is further rotated in the removal direction, as shown in the front view of FIG. 7, the cap 117 moves upward and detaches from the mouth portion 108. At this time, as shown in the same figure, the ring 118 remains attached to the container body 101 in a state of being fitted in the annular groove portion 115.

[0074] The user grips the grip portion 106 of the container body 101 (see the front view of FIG. 8) with the ring 118 attached. Then, by positioning the grip portion 106 vertically upward and laying the grip axis GL horizontally, the liquid flows out from the inside of the liquid container 100 to the outside through the spraying port 123 due to its own weight.

[0075] Here, FIG. 9 is a diagram showing a cross-section of the grip portion 106 along the line A-A in FIG. 8. As shown in the portion surrounded by the dotted line DC in the figure, the finger-hooking portion 111 according to the present embodiment has a shape protruding toward the body portion 105 in a cross-section perpendicular to the grip axis GL. As a result, a ridge line is formed approximately at the center in the front-rear direction on the proximal surface of the grip portion 106, and the finger-hooking portion 111 includes at least a part of the portion forming the ridge line.

[0076] Generally, when a person holds an object, due to the structure of the human body, it is said that a particularly large gripping force can be exerted by holding the object in a manner called a hammer grip. The hammer grip is a way of holding an object by enclosing one surface of the object with the hand and fingers while supporting it, and receiving the surface opposite to the one surface with the palm surface, and is also called a power grip or the like.

[0077] Since the finger-hooking portion 111 has a shape protruding toward the body portion 105 as described above, it is possible to easily hold the grip portion 106 in a hammer grip. Therefore, it becomes possible to improve the convenience for the user.

[0078] Also, on the distal surface of the grip portion 106, a ridge line is formed approximately at the center in the front-rear direction, similarly to the proximal surface of the grip portion 106. And it is desirable that the ridge line on the distal surface of the grip portion 106 and the ridge line on the proximal surface of the grip portion 106 are substantially parallel. Here, the distal surface of the grip portion 106 is the surface far from the body portion 105.

[0079] In this way, by providing a ridge line on the distal surface that is substantially parallel to the ridge line on the proximal surface, it is possible to easily hold the grip portion 106 in a hammer grip. Therefore, it becomes possible to improve the convenience for the user.

[0080] Furthermore, in the present embodiment, as shown in FIG. 9, in the cross-section of the grip portion 106 perpendicular to the grip axis GL, the radius of curvature R1 near the ridge line of the distal surface is larger than the radius of curvature R2 near the ridge line of the proximal surface. That is, in the cross-section of the grip portion 106 perpendicular to the grip axis GL, the portion near the ridge line of the distal surface is smoother than the portion near the ridge line of the proximal surface.

[0081] As an example of the dimensions of the grip portion 106, the width W in FIG. 9 is 36 mm, the height H is 30 mm, the radius of curvature R1 is 25 mm, and the radius of curvature R2 is 10 mm.

[0082] Generally, when a person holds a round bar, by bringing the thumb into contact with the index finger or the middle finger and gripping so as to surround the round bar, the round bar can be stably held. For the general hand size of a person, the diameter of the round bar that can be gripped so as to surround it is 36 to 40 mm. Therefore, it is desirable that the cross-section of the grip portion 106 be sized to be inscribed in a circle with a diameter of 36 to 40 mm.

[0083] The above dimensions of the grip portion 106 are an example of the size where the cross-section of the grip portion 106 is inscribed in a circle with a diameter of 36 mm. Therefore, the grip portion 106 can be made easier to grip. Accordingly, it becomes possible to improve the convenience for the user.

[0084] Also, since the finger hook portion 111 protrudes toward the body portion 105, when the user holds the grip portion 106, the four fingers that come into contact with the finger hook portion 111 are caught by the finger hook portion 111. This also makes the grip portion 106 easier to grip. Accordingly, it becomes possible to improve the convenience for the user.

[0085] Furthermore, the vicinity of the apex of the portion protruding toward the body portion 105 is formed of a curve and has a round shape. Therefore, when weight is applied to the four fingers that come into contact with the finger hook portion 111, the four fingers are less likely to hurt than when the vicinity of the apex of the portion is sharp. This also makes the grip portion 106 easier to grip. Accordingly, it becomes possible to improve the convenience for the user.

[0086] When spraying the liquid, the spraying surface portion 121 is preferably inclined downward by 8 to 12 degrees with respect to the state of being perpendicular to the horizontal plane. That is, the angle α (the angle of the spraying surface portion 121 with respect to the vertical plane including the lower end in the vertical direction of the spraying surface portion 121) shown in FIG. 10 is preferably 8 to 12 degrees. When the spraying surface portion 121 is inclined in this way, the liquid smoothly flows out from the liquid container 100. In addition, the weight balance of the liquid container 100 between the portion located in front of the center of gravity G during spraying and the portion located behind the center of gravity G during spraying becomes good, and it becomes easier for the user to hold the liquid container 100.

[0087] Here, as shown in FIG. 10, the front during spraying is the direction in the horizontal direction in which the spraying surface portion 121 is located with respect to the overall center of gravity G of the container body 101 that contains a specified volume of liquid. The rear during spraying is the opposite direction of the front during spraying, that is, the direction in the horizontal direction in which the bottom portion 104 is located with respect to the center of gravity G. Also, the lower side during spraying shown in the same figure is vertically downward, and the upper side during spraying is vertically upward.

[0088] In the liquid container 100 according to the present embodiment, the user may naturally grip the grip portion 106 by relaxing the force of the wrist near the area where the liquid is sprayed. As a result, the grip axis GL lies horizontally and is inclined slightly downward vertically as shown in FIG. 10. Since the grip axis GL is inclined with respect to the central axis C as described above, the spraying surface portion 121 is inclined downward vertically with the angle α being 8 to 12 degrees.

[0089] As described above, since the grip axis GL is inclined with respect to the central axis C, the spraying surface portion 121 can be inclined downward vertically simply by the user naturally gripping the grip portion 106 without applying too much force to the wrist or the like. Thereby, the fatigue of the user's hand, wrist, arm, etc. when spraying the liquid can be reduced. Therefore, it becomes possible to improve the convenience for the user.

[0090] Particularly in this embodiment, the inclination angle θ of the grip axis GL with respect to the central axis C is 5 to 7 degrees. As a result, while suppressing an increase in the width (length in the left - right direction) of the container body 101, by simply gripping the grip portion 106 naturally, the spraying surface portion 121 can be inclined downward vertically. Since an increase in the size of the container body 101 can be suppressed, the space utilization efficiency during storage or transportation of the liquid container 100 can be improved. At the same time, it is also possible to reduce the fatigue of the user's hand, wrist, arm, etc. when spraying the liquid. Therefore, it becomes possible to further improve the convenience for the user.

[0091] When the spraying surface portion 121 is inclined downward vertically, as described above, the liquid is sprayed by flowing out from the spraying port 123. In this embodiment, by providing the middle lid 103 having the spraying port 123, the liquid can be sprayed over a relatively wide range.

[0092] After spraying in the desired area, the user can cover the spraying port 123 by screwing the cap 117 back onto the male screw portion 114. Thereby, the use of the liquid container 100 is completed. In addition, when transferring the liquid from the container body 101 to another container, etc., the middle lid 103 may not be provided.

[0093] Here, generally, when the spraying time becomes long, the hand, wrist, arm, etc. that grip the grip portion 106 may become fatigued. Particularly when there is a large amount of liquid stored in the container body 101, the hand, wrist, arm, etc. may become fatigued even in a relatively short time. Also, when spraying the liquid, in order to spray the liquid into the desired area, the container body 101 may be shaken back and forth or left and right, and the hand, wrist, arm, etc. may also become fatigued due to such operations.

[0094] In the liquid container 100 according to the present embodiment, as described above, since the grip portion 106 has a shape that is easy to hold and the grip axis GL is inclined with respect to the central axis C, it is possible to reduce the fatigue of the user's hand, wrist, arm, etc. during spraying. In addition to these, the liquid container 100 has the following features in order to reduce the fatigue of the user's hand, wrist, arm, etc. during use.

[0095] (Position of the grip portion 106 in the container body 101 and its action and effect) The grip portion 106 includes a portion located above the center of gravity G (i.e., vertically above) during spraying when the grip axis GL is oriented horizontally.

[0096] Particularly in the present embodiment, when the grip portion 106 is gripped by the user and the grip axis GL is oriented horizontally, the portion located vertically above the center of gravity G is positioned between the index finger and the middle finger of the user.

[0097] As a result, as shown in FIG. 10, when the user releases the force of the wrist and grips the grip portion 106 so that the grip axis GL is oriented slightly vertically downward from the horizontal, the grip portion 106 is easily positioned above the center of gravity G during spraying. Also, in the container body 101 containing a liquid of a specified capacity, the weights in front of and behind the center of gravity G during spraying are substantially equal via the center of gravity G. Therefore, the burden on the user's hand, wrist, arm, etc. during spraying can be reduced. Accordingly, it becomes possible to improve the convenience for the user.

[0098] (Action and effect of the thumb contact portion 107) When the user grips the grip portion 106, by bringing the thumb into contact along the thumb contact portion 107, it becomes easier to hold the grip portion 106 with a hammer grip. Therefore, the burden on the user's hand, wrist, arm, etc. during spraying can be reduced. Accordingly, it becomes possible to improve the convenience for the user.

[0099] In this embodiment, since the unevenness is provided on the thumb contact portion 107, when the grip portion 106 is gripped, the user can be prompted to bring the thumb into contact with the thumb contact portion 107. Also, the thumb in contact with the thumb contact portion 107 can be made less slippery. As a result, the user can more easily grip the grip portion 106 in a hammer grip. Therefore, the burden on the user's hand, wrist, arm, etc. during spraying can be further reduced. Accordingly, it becomes possible to further improve the convenience for the user.

[0100] (Function and effect of the unevenness of the finger hook portion 106) In this embodiment, since the unevenness is provided on the finger hook portion 106, the four fingers in contact with the finger hook portion 106 can be made less slippery. As a result, the user can more easily grip the grip portion 106 in a hammer grip. Therefore, the burden on the user's hand, wrist, arm, etc. during spraying can be further reduced. Accordingly, it becomes possible to further improve the convenience for the user.

[0101] (Function and effect of the auxiliary support portion 109) In this embodiment, since the auxiliary support portion 109 is provided, the user can place the fingers of the hand opposite to the hand gripping the grip portion 106 on the auxiliary support portion 109 during spraying. As a result, the user can easily hold the container body 101 containing the liquid. Therefore, the burden on the user's hand, wrist, arm, etc. during spraying can be reduced. Accordingly, it becomes possible to improve the convenience for the user.

[0102] Also, a concave portion 116 is provided in the auxiliary support portion 109 according to this embodiment. Therefore, it becomes easier to place the fingers of the hand opposite to the hand gripping the grip portion 106 in the concave portion 116. As a result, the user can more easily hold the container body 101 containing the liquid. Therefore, the burden on the user's hand, wrist, arm, etc. during spraying can be further reduced. Accordingly, it becomes possible to further improve the convenience for the user.

[0103] Furthermore, the auxiliary support portion 109 according to the present embodiment is hollow. Therefore, during spraying, the liquid flows into the auxiliary support portion 109.

[0104] For example, when the user wants to increase the amount of liquid flowing out of the spraying port 123, if the grip axis GL is inclined so that the front during spraying faces vertically downward, more liquid will flow into the auxiliary support portion 109. The liquid that has flowed into the auxiliary support portion 109 acts such that the overall weight balance of the container body 101 containing the liquid biases forward during spraying. As a result, with a relatively small force, the spraying surface portion 121 can be directed vertically downward at a larger angle α, and the amount of liquid flowing out of the spraying port 123 can be increased.

[0105] Also, for example, the same applies when the user wants to reduce the amount of liquid flowing out of the spraying port 123. In this case, if the grip axis GL is inclined so that the front during spraying faces vertically upward, the liquid in the auxiliary support portion 109 will flow out. The liquid that has flowed out of the auxiliary support portion 109 acts such that the overall weight balance of the container body 101 containing the liquid biases rearward during spraying. As a result, with a relatively small force, the spraying surface portion 121 can be directed vertically downward at a smaller angle α, and the amount of liquid flowing out of the spraying port 123 can be reduced.

[0106] In this way, since the auxiliary support portion 109 is hollow, the amount of liquid flowing out of the spraying port 123 can be easily adjusted. Therefore, it becomes possible to further improve the convenience for the user.

[0107] So far, one embodiment of the present invention has been described. According to the liquid container 100 of the present embodiment, due to the characteristics of each part described so far, it becomes possible to improve the convenience for the user.
