[Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-111111 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the cooler container in Patent Document 1 has a spout on the upper wall that tapers towards the tip, so when the beverage is poured out of the spout, it is poured through a narrow width. This means that when the beverage hits a container such as a cup, the beverage splashes up and the impact of hitting the water can cause foaming. The present invention has been made in consideration of the above-mentioned problems, and has an object to suppress the liquid from splashing up by pouring liquid in a wide state from the pouring outlet. [Means for solving the problem]

[0005] The present invention is a pitcher comprising a container-shaped main body having a spout formed along the width direction of an opening, and a lid attached to the main body, wherein the lid has a lid body and a partition wall extending downward from the lid body and positioned away from the inner surface of the opening, and the partition wall is formed in a convex arc shape from the spout toward the opposite side when viewed from the bottom. Effect of the Invention

[0006] According to the present invention, the liquid is poured out from the pouring outlet in a wide state, so that splashing of the liquid can be suppressed. [Brief description of the drawings]

[0008] Hereinafter, a pitcher according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of the configuration of the pitcher 100. FIG. 2 is a view showing an example of the configuration of the pitcher 100, in which FIG. 2(a) is a plan view, FIG. 2(b) is a side view seen from the front side, and FIG. 2(c) is a front view. FIG. 3 is a cross-sectional view taken along line II in FIG. 2, FIG. 4(a) is a cross-sectional view taken along line II-II in FIG. 2, FIG. 4(b) is an enlarged cross-sectional view, and FIG. 5 is a cross-sectional view taken along line III-III in FIG. 2. In each drawing, the side of the spout 21 described later is shown as the front, and the opposite side is shown as the rear. The direction along the front and rear is called the front-rear direction. In each drawing, one side of the horizontal direction perpendicular to the front-rear direction is shown as the right, and the other side is shown as the left. The direction along the left and right is called the width direction or the left-right direction.

[0009] Pitcher 100 comprises a main body portion 10 and a lid portion 30. First, a description will be given of the main body 10. FIG 6 is a plan view of the main body 10. The main body 10 is in the form of a container having an opening 20 at the top. The main body 10 is made of a material such as transparent synthetic resin or transparent glass so that the user can confirm the presence of liquid inside. The main body 10 has an outer shape of a substantially rectangular parallelepiped with rounded corners. Specifically, the main body 10 has a substantially rectangular shape that is longer in the front-rear direction than in the width direction (left-right direction) in a plan view. The width of the main body 10 is a length that allows a user to hold it in one hand. The main body 10 also has a substantially symmetrical shape.

[0010] Moreover, the main body 10 has a generally rectangular shape that is longer in the up-down direction than in the front-to-back direction when viewed from the front (see FIG. 2(c)). The main body 10 has a generally symmetrical shape in the front-to-back direction except for the area where the opening 20, which will be described later, is formed. Moreover, the main body 10 has a generally rectangular shape that is longer in the up-down direction than in the width direction when viewed from the side (see FIG. 2(b)).

[0011] The main body 10 has side plates 11a to 11d and a bottom plate 14. The side plates 11a to 11d and the bottom plate 14 are integrally formed. The side plate portions 11a and 11b are positioned facing each other in the front and rear across the space in the main body portion 10. As shown in FIG. 2(c), the side plate portions 11a and 11b are gently inclined so as to approach each other from the opening 20 toward the bottom plate portion 14. The side plate portions 11c and 11d are positioned facing each other in the left and right across the space in the main body portion 10. As shown in FIG. 2(b), the side plate portions 11c and 11d are gently inclined so as to approach each other from the opening 20 toward the bottom plate portion 14. In addition, the corners at which adjacent side plate portions among the side plate portions 11a to 11d are connected to each other are formed to be curved. When the side plate portions are connected to each other in a curved manner in this way, the intermediate position between the position where one side plate portion starts to curve and the position where the other side plate portion starts to curve among the adjacent side plate portions can be set as the boundary between the adjacent side plate portions.

[0012] Further, side plates 11c and 11d each have a recess 12 near the center in the front-rear direction on the outer surface (see FIG. 5). Recess 12 is formed from the center in the up-down direction of the outer surfaces of side plates 11c and 11d to the lower end, so as to gently recess toward the space inside main body 10. When a user lifts pitcher 100 or tilts pitcher 100 to pour liquid, the user can improve the grip of main body 10 by holding pitcher 100 so that the index finger to little finger are in contact with recess 12 of side plate 11c and the thumb is in contact with recess 12 of side plate 11d.

[0013] In addition, the side plates 11c and 11d each have a grip portion 13a, 13b at the upper part of the outer surface (see FIG. 5). The grip portions 13a, 13b are formed over a certain range in the center of the front-rear direction of the side plates 11c and 11d. The grip portions 13a, 13b are formed by curving the outer surfaces of the side plates 11c and 11d so that they move away from each other toward the upper end. When the user lifts the pitcher 100, for example, the user can improve the grip of the main body 10 by holding the pitcher so that the index finger to the little finger are hooked on the grip portion 13a of the right side plate 11c and the thumb is hooked on the grip portion 13b of the left side plate 11d.

[0014] The inner surfaces of the handles 13a, 13b, i.e., the inner surface of the right side plate 11c and the inner surface of the left side plate 11d, are also curved away from each other toward the upper end. By curving the inner surfaces of the handles 13a, 13b away from each other in this manner, mating walls 34a, 34b (described later) of the cover 30 can be guided into the opening 20 when the cover 30 is attached to the main body 10.

[0015] The bottom plate portion 14 is located at the lower end of the main body portion 10. Although not shown, the bottom plate portion 14 has a substantially rectangular shape when viewed from the bottom. The corners where the lower ends of the side plate portions 11a to 11d and the outer periphery of the bottom plate portion 14 are connected are curved.

[0016] The main body 10 has an opening 20 at the top of the side plates 11a to 11d. A lid 30 is attached to the opening 20. The opening 20 here is not limited to only the upper ends of the side plates 11a to 11d (the upper end of the main body 10), but refers to a certain range in the vertical direction from the upper ends of the side plates 11a to 11d to a position where the lid 30 fits. 6, the opening 20 has a generally rectangular shape that is longer in the front-rear direction than in the width direction in a plan view, similar to the main body 10. The generally rectangular shape of the opening 20 is formed by side plate portions 11a, 11b facing each other in the front-rear direction and side plate portions 11c, 11d facing each other in the left-right direction.

[0017] The opening 20 has a spout 21 formed on the front side. That is, the main body 10 has the spout 21 on the front side and at the top. The spout 21 allows liquid in the main body 10 to be poured out. The spout 21 is formed by curving the inner surface of the front side plate 11a toward the top end. The spout 21 has a wide shape along the width direction. Specifically, the spout 21 is formed over substantially the entire upper area of ​​the front side plate 11a. Here, if the front side plate 11a constituting the substantially rectangular shape of the opening 20 in a plan view is referred to as one side, the spout 21 is formed along one side of the opening 20. The spout 21 does not necessarily have to be formed over substantially the entire upper area of ​​the front side plate 11a, but may be formed over at least 1 / 2 or at least 2 / 3 of the entire upper area of ​​the side plate 11a.

[0018] 6, if the amount of protrusion of spout 21 protruding forward from the inner surface of side plate portion 11a is P, protrusion amount P is longest at the center (center line C1) of the width of main body portion 10 and becomes shorter as it moves away from the center in the width direction. Specifically, in a plan view, the front end of spout 21 is formed in a circular arc shape that protrudes forward. Note that in this embodiment, spout 21 is formed only on the front side of opening 20, and no spout is formed on the rear side, so that opening 20 is asymmetrical front to back.

[0019] 4(a) and 4(b), the inner surface of the spout 21 is curved in an arc so that the liquid in the main body 10 can be smoothly poured out. The outer surface of the spout 21 is also curved in an arc. Here, if the radius of curvature of the arc of the outer surface of the spout 21 is Ro and the radius of curvature of the arc of the inner surface of the spout 21 is Ri, the relationship of the radius of curvature Ro > radius of curvature Ri is set. By gently curving the outer surface of the spout 21 in this way, the design of the main body 10 can be improved.

[0020] Next, the cover portion 30 will be described. FIG. 7 shows an example of the configuration of the cover 30, where FIG. 7(a) is a side view, FIG. 7(b) is a front view, and FIG. 7(c) is a bottom view. The lid part 30 is attached to the opening 20 of the main body part 10. The lid part 30 is a member that is deformable so as to come into close contact with the opening 20 when attached to the opening 20, and is made of a material such as rubber or soft synthetic resin. The cover portion 30 has a flat outer shape. The cover portion 30 has a substantially symmetrical shape in the front-rear direction and in the left-right direction.

[0021] The lid portion 30 has a lid main body 31 and a side wall portion 33. The lid main body 31 and the side wall portion 33 are integrally formed. The lid body 31 covers the main body 10 from above. The lid body 31 is generally plate-shaped with a wide surface formed along a generally horizontal direction. The lid body 31 is generally rectangular in shape with rounded corners and is longer in the front-rear direction than in the width direction when viewed from the bottom (or in a plan view). When attached to the main body 10, the lid 30 is shaped so that it can cover most of the opening 20 from above, except for the above-mentioned pouring outlet 21. The lid body 31 has flat upper and lower surfaces that are parallel to each other.

[0022] The side surface 32 of the lid body 31 is an inclined surface inclined with respect to a vertical plane. Specifically, the side surface 32 of the lid body 31 is inclined toward the inside of the lid body 31, i.e., toward the center O, from the upper end to the lower end. By inclining the side surface 32 of the lid body 31 in this manner, a small gap is generated between the upper end of the main body 10 and the lid body 31, and the lid body 31 can be removed by inserting a finger into the gap. The side surface 32 of the lid body 31 in this embodiment is inclined all around, but may be inclined intermittently along the entire circumference.

[0023] The side wall portion 33 is a portion extending downward from the lid main body 31. In bottom view, the side wall portion 33 is formed by extending downward from a position on the lower surface of the lid main body 31 away from the outer peripheral edge (or side surface 32) toward the center O. The length of the side wall portion 33, i.e., the length Lw from the lower surface of the lid main body 31 to the lower end of the side wall portion 33, is greater than the thickness Tc of the lid main body 31 (see FIG. 7(b)). Here, the side wall portion 33 is formed in an annular shape surrounding the center O in bottom view. The space surrounded by the side wall portion 33 opens downward. Here, the side wall portion 33 has fitting walls 34a, 34b and separating walls 35a, 35b.

[0024] The fitting walls 34a, 34b are walls for fitting the cover portion 30 into the opening 20 of the main body portion 10. The fitting walls 34a and 34b are positioned opposite each other on the left and right sides of the center O in a bottom view, and have a substantially symmetrical shape. The fitting walls 34a, 34b are formed at positions spaced apart from the outer periphery (or side surface 32) of the lid body 31 toward the center O at an approximately constant interval in bottom view. That is, the fitting walls 34a, 34b are approximately similar in shape to the outer periphery of the lid body 31 reduced in size. Specifically, the fitting walls 34a, 34b extend approximately linearly in the front-rear direction near the center in the front-rear direction in bottom view, and curve toward the center line C1 as they approach the front and rear ends. The shape of the fitting walls 34a, 34b in bottom view approximately matches the shape of the portion that fits into the opening 20 of the main body 10. Therefore, when the lid 30 is attached to the opening 20 of the main body 10, the fitting walls 34a, 34b can be brought into close contact with the inner side surface of the opening 20. Specifically, the fitting wall 34a comes into close contact with the inner surface of the side plate portion 11c of the main body portion 10, and the fitting wall 34b comes into close contact with the inner surface of the side plate portion 11d of the main body portion 10. The front ends of the fitting walls 34a, 34b are connected to the separation wall 35a, and the rear ends of the fitting walls 34a, 34b are connected to the separation wall 35b.

[0025] Of the separating walls 35a and 35b, the separating wall 35a located on the front side is a wall for forming a water storage space S described later. The separating walls 35a and 35b are located facing each other in the front and rear directions with the center O in between in a bottom view, and are substantially symmetrical in the front and rear directions. The separating wall 35a is formed to connect the front ends of the fitting walls 34a and 34b to the left and right, and the separating wall 35b is formed to connect the rear ends of the fitting walls 34a and 34b to the left and right. Of the separating walls 35a and 35b, the separating wall 35a located on the front side is located on the side of the spout 21 when the lid 30 is attached to the main body 10.

[0026] Here, unlike the fitting wall 34a, the separating walls 35a and 35b are not similar in shape to the outer peripheral edge (or side surface 32) of the lid body 31 in a bottom view, and are formed at positions that are further away from the outer peripheral edge of the lid body 31 as they move away from the fitting walls 34a and 34b, respectively. Specifically, the separating walls 35a and 35b are formed to be curved convexly in a direction away from the outer peripheral edge of the lid body 31 in a bottom view. Such shapes of the separating walls 35a and 35b in a bottom view do not match the shapes of the parts that fit into the opening 20 of the main body 10, and are separated (separated) from the inner surface of the opening 20 when the lid 30 is attached to the opening 20 of the main body 10. Specifically, the separating wall 35a is separated from the inner surface of the side plate portion 11a of the main body 10, and the separating wall 35b is separated from the inner surface of the side plate portion 11b of the main body 10.

[0027] When attaching the lid 30 configured as described above to the main body 10, the user positions the lid 30 above the opening 20 of the main body 10 and then pushes the lid 30 downward toward the main body 10 to attach it. At this time, the pair of fitting walls 34a, 34b of the lid 30 are inserted into the opening 20 while being guided by the inner surfaces of the above-mentioned grips 13a, 13b of the main body 10, i.e., the curved portions of the inner surfaces of the side plate portions 11c, 11d. The user pushes the lid 30 in until the bottom surface of the lid body 31 contacts the upper end of the main body 10, thereby completing the attachment of the lid 30.

[0028] When the lid 30 is attached to the main body 10, the fitting walls 34a, 34b are in close contact with the inner surfaces of the side plates 11c, 11d of the main body 10 as described above, so that the fitting walls 34a, 34b and the side plates 11c, 11d are sealed so that liquid does not leak between them. Meanwhile, the front separation wall 35a is separated from the inner surface of the side plate 11a of the main body 10, so that a water storage space S is formed that is surrounded by the outer surface of the separation wall 35a, the inner surface of the side plate 11a (the inner surface of the opening 20), and the lower surface of the lid body 31 of the lid 30. The water storage space S is in communication with the spout 21, and can temporarily store liquid poured out from the spout 21. Note that the rear separation wall 35 also forms a space in the same way, but it does not communicate with the spout 21 and does not function as a water storage space.

[0029] Here, the water storage space S will be described with reference to Figures 3 and 4. In Figures 3 and 4, the water storage space S is shown colored gray. As shown in FIG. 3, the water storage space S is located at the front and widthwise center of the pitcher 100 in plan view (or bottom view). The water storage space S is a space whose widthwise length Ws is longer than its front-rear length Ls. In this embodiment, the widthwise length Ws of the water storage space S is approximately 3 / 5 of the widthwise length W of the main body 10. The widthwise length Ws of the water storage space S is preferably 1 / 2 or more of the widthwise length W of the main body 10 in order to pour a wide liquid from the spout 21. On the other hand, if the widthwise length Ws of the water storage space S is large, the ratio of the separation wall 35a to the side wall 33 becomes large, and the ratio of the fitting walls 34a, 34b becomes small, making it easier for the lid 30 to come off. Therefore, it is preferable that the widthwise length Ws of the water storage space S is smaller than the widthwise length W of the main body 10. Moreover, the water storage space S has a generally elliptical shape tapered toward the right and left ends in plan view (or bottom view), and has a so-called rugby ball shape.

[0030] As shown in Figures 4(a) and (b), the water storage space S is located at the front and upper part of the pitcher 100 in a side view, facing the spout 21 in the front-rear direction. As shown in Figure 4(b), the position of the lower end of the water storage space S is preferably lower than the bending start position P1 where the inner surface of the spout 21 starts bending forward so that liquid can be temporarily stored in the water storage space S. On the other hand, if the position of the lower end of the water storage space S is too low, it becomes difficult for liquid in the main body 10 to flow into the water storage space S, so the position of the lower end of the water storage space S is preferably higher than position P2. Position P2 is a position that is twice the distance Lr from the upper end of the spout 21 to position P1.

[0031] As shown in FIG. 2(b), when the pitcher 100 is viewed from the front side (the side of the spout 21 and in the horizontal direction), the separating wall 35a is visually recognized as being located between the pair of fitting walls 34a, 34b through the transparent main body 10. In this case, the position of the lower end of the pair of fitting walls 34a, 34b and the position of the lower end of the separating wall 35a are the same. In other words, since the lower ends of the pair of fitting walls 34a, 34b and the lower end of the separating wall 35a are continuous in a straight line in the horizontal direction, the appearance (design) of the lid 30 seen through the transparent main body 10 can be improved.

[0032] Next, a case where liquid within main body 10 is poured out in pitcher 100 configured as described above will be described. The user holds pitcher 100 so that the index finger through little finger are in contact with recess 12 of side panel portion 11c and the thumb is in contact with recess 12 of side panel portion 11d, and then tilts pitcher 100 as a whole so that spout 21 is closer to a cup or the like. First, assume that the user suddenly tilts pitcher 100. At this time, the liquid in the main body 10 flows toward the outlet 21 at once, but some of the liquid hits the inner surface of the partition wall 35a located on the outlet 21 side. In FIG. 3, the liquid flowing toward the inner surface of the partition wall 35a is indicated by arrows. A part of the liquid (arrow A1) that hits the inner surface of the partition wall 35a near the center in the width direction passes through the lower end of the partition wall 35a and flows toward the outlet 21, but is decelerated by hitting the partition wall 35a. The remaining liquid (arrow A2) that hits the inner surface of the partition wall 35a near the center while still decelerating, passes through the lower end of the partition wall 35a while spreading left and right along the inner surface of the arc of the partition wall 35a, and flows toward the outlet 21. Therefore, even if the user suddenly tilts the pitcher 100, the liquid can be poured from the outlet 21 in a sufficiently decelerated state and in a wide state that spreads left and right.

[0033] Next, a normal dispensing method will be described with reference to Figs. 8(a) and 8(b). FIG. 8(a) is a cross-sectional view showing a state in which liquid is being poured out from the pouring outlet 21. FIG. As shown in FIG. 8(a), when a user pours liquid from the spout 21, the user tilts the pitcher 100 at an angle so that the liquid is always stored in the water storage space S, i.e., so that the water storage space S is filled evenly. At this time, the liquid that has filled the water storage space S is poured out through the connected spout 21, but the flow rate toward the spout 21 is regulated by the lid body 31 that covers the top of the water storage space S. Therefore, a constant flow rate of liquid always flows from the water storage space S toward the spout 21 along the width of the water storage space S. In other words, the liquid in the water storage space S that cannot flow toward the spout 21 is temporarily stored in the water storage space S.

[0034] FIG. 8(b) is a view from the direction of arrow B showing the state in which liquid is being poured out from spout 21 as shown in FIG. 8(a). As shown in FIG. 8(b), liquid that flows toward spout 21 with a length Ws in the width direction of water storage space S is poured out from spout 21 as is. Therefore, when a user tilts pitcher 100 to pour liquid from spout 21, liquid can be poured out in a wide state that spreads out to the left and right from spout 21. By pouring liquid out from spout 21 to the outside while tilting pitcher 100 so that the liquid is always stored in water storage space S, the user can pour liquid in a wide state, thereby realizing a flowing water shape with excellent aesthetics.

[0035] The above-mentioned separation wall 35a and separation wall 35b of the lid part 30 are substantially symmetrical in front-to-back view in bottom view. Therefore, the lid part 30 can be attached to the main body part 10 even if the front-to-back direction is reversed, and when the front-to-back direction of the lid part 30 is reversed, the separation wall 35b functions in the same way as the above-mentioned separation wall 35a. Therefore, the user can attach the lid part 30 to the main body part 10 without being aware of the front-to-back direction.

[0036] As described above, according to the present embodiment, the lid 30 has the lid body 31 and the partition wall 35a extending downward from the lid body 31 and positioned away from the inner surface of the opening 20, and the partition wall 35a is formed in a convex arc shape facing away from the spout 21 when viewed from the bottom. With this type of lid 30, when the user tilts the pitcher 100, the liquid that strikes the inner surface of the partition wall 35a near the center in the width direction spreads left and right along the inner surface of the arc of the partition wall 35a while remaining in a decelerated state, passes under the lower end of the partition wall 35a, and flows toward the spout 21. Therefore, the liquid can be poured out from the spout 21 in a wide state, and therefore splashing and foaming of the liquid can be suppressed.

[0037] Furthermore, according to this embodiment, a water storage space S is formed that is surrounded by the outer surface of the separating wall 35a, the inner surface of the opening 20, and the underside of the lid body 31, and when the user tilts the pitcher 100, the liquid temporarily stored in the water storage space S flows out from the spout 21. Therefore, the liquid can be poured out in a wide state from the spout 21, which makes it possible to suppress splashing and foaming of the liquid.

[0038] Although the present invention has been described above with reference to the above-mentioned embodiment, the present invention is not limited to the above-mentioned embodiment, and modifications and the like are possible within the scope of the present invention.
