Description

The present invention relates to a container.

Containers for liquids are used to cool liquids such as water, tea, and soft drinks in a refrigerator or to serve them at the dining table. For example, Patent Document 1 discloses a container that has a bottomed container body for holding liquid and a lid member for closing the top opening of the container. The container body described in Patent Document 1 has a cylindrical body with a bottom and a lid member attachment portion (male thread portion) provided on the top of the body.

The lid member has a lid body that is attached to the lid body attachment part of the container body and has a liquid passage hole, and a pouring lid that is attached so as to be able to swing relative to the lid body so as to open and close the liquid passage hole. The lid body has an attachment part (female thread part) that is attached to the lid body attachment part of the container body, and a top plate part for closing the upper opening of the container, and the top plate part is provided with a liquid passage hole.

The liquid contained in the container body is poured out through the liquid passage hole in the lid member by tilting the container while the pouring lid is operated to open the liquid passage hole.

JP 2015-71444 A

However, in the container described in Patent Document 1, the body of the container body is formed in a cylindrical shape, so if multiple containers are placed adjacent to each other in a refrigerator door pocket, for example, gaps will form between the bodies, resulting in an ineffective use of the storage space.

The present invention was made in consideration of these problems, and aims to provide a container that can make effective use of storage space.

After extensive investigation, the inventors have found that the above object can be achieved by the following invention.

The container according to one aspect of the present invention is a container for storing liquid, and includes a container body having a bottomed cylindrical body and a lid member attachment part provided at the top of the body, and opening upward; a mounting part attached detachably to the lid member attachment part; a top plate attached to the mounting part so as to close the opening of the container body when the mounting part is attached to the lid member attachment part and having a liquid passage hole for passing the liquid; and a lid member having a pouring lid attached to the top plate so as to be swingable relative to the top plate so as to open and close the liquid passage hole, and the body has a substantially rectangular outer shape in a plan view.

According to the first invention, since the body has a substantially rectangular outer shape, by arranging multiple containers so that the rectangular sides of each body face each other, the gaps between the multiple containers can be kept small.

In the second invention, in the first invention, the lid member attachment portion has a female thread formed within the range of the planar shape of the body in a plan view, the attached portion has a cylindrical shape that extends downward from the top plate and has an outer circumferential surface on which a male thread is formed, and it is preferable that the top plate has an outer surface shape that is substantially the same as the outer surface shape of the body in a plan view.

As for the configuration of the lid member attachment portion of the container body and the attached portion of the lid member, it is conceivable to use male threads for the lid member attachment portion and female threads for the attached portion, similar to the container described in Patent Document 1.

In this case, to give the lid member and the container body a unified appearance, the outer shape of the attachment portion must be substantially the same as the outer shape of the body.

However, because the inner circumferential surface of the female thread is circular, if the mounting portion is formed as a solid part when the lid member is molded from synthetic resin, the change in thickness of the mounting portion in the direction of rotation of the screw, i.e., the change in the thermal shrinkage rate during molding, will be large, resulting in so-called sink marks and making it difficult to form the desired shape. To solve this problem, it is conceivable to make the outer circumferential surface of the mounting portion cylindrical and provide the lid member with a peripheral wall that surrounds the mounting portion and has an outer surface shape that is substantially the same as the outer surface shape of the body portion in a plan view. However, in this case, a narrow space will be created between the cylindrical surface and the peripheral wall, making it difficult to clean the lid member.

Therefore, in the second invention, the lid member attachment portion has a female thread, and the attached portion of the lid member extends downward from the top plate and has a male thread. As a result, the part of the attached portion that screws into the female thread of the lid member attachment portion is inserted into the container body and is not exposed to the outside.

Therefore, as in the second invention, by having the top plate have an outer shape that is substantially the same as the outer shape of the body in a plan view, the container as a whole can have a unified appearance, improving the appearance of the container. Since there is no need to create a narrow space between the top plate and the attachment portion to achieve the above-mentioned unified appearance, the lid member can also be easily washed.

The third invention is the second invention, wherein the liquid passage hole has an overlapping portion that overlaps in a plan view with the internal space of the threaded region of the attached part where the male thread is formed, and an extension portion that extends from the overlapping portion to an outer position of the internal space in a plan view, the attached part has a bulging portion that extends upward from the threaded region and bulges horizontally from the threaded region so as to cover the extension portion from the side, and the lid member preferably has a spout that rises upward from an edge portion of the top plate adjacent to the bulging direction of the bulging portion and for guiding the liquid that is drawn out through the liquid passage hole.

According to the third invention, the extension portion can expand the liquid passage hole to a position close to the spout, shortening the liquid path from the liquid passage hole to the spout. As a result, when the container is tilted to pour liquid and then placed upright, the amount of liquid remaining on the top plate can be reduced, and the liquid remaining on the top plate can be prevented from being unintentionally discharged when the container is tilted, etc.

In the fourth invention, in the third invention, it is preferable that the container body has a covering portion that extends upward from the body portion, covers the bulge portion from the side, and has an outer shape that is substantially the same as the outer shape of the body portion in a plan view.

The bulge has a diameter dimension larger than the threaded area, so it cannot be contained inside the female thread and is exposed to the side. Here, in the fourth invention, a covering portion is provided, so the bulge is covered from the side while still providing a unified appearance to the entire container.

The fifth invention is the third or fourth invention, in which the lid member preferably has a pair of guide walls erected on the top plate so as to face each other in a direction perpendicular to the expanding direction with the liquid passage hole between them and extend from the liquid passage hole to the spout along the expanding direction.

According to the fifth invention, when the container is tilted so that the spout faces downward, the liquid that is drawn out from the liquid passage hole can be reliably guided along the guide wall to the spout.

In the sixth invention, in the fifth invention, it is preferable that the pouring lid is attached to the top plate between the pair of guide walls so that it can swing around an axis extending in the perpendicular direction.

According to the sixth invention, the space between the guide walls can be utilized to attach the pouring lid to the top plate in a swingable state.

The seventh invention is any one of the third to sixth inventions, in which the extension portion extends from the overlapping portion along a diagonal of the rectangular outer surface shape of the top plate in a plan view, and the spout is preferably provided at a corner of the rectangular outer surface shape of the top plate.

According to the seventh invention, the corner of the top plate where the spout is provided is a sharp point in the planar shape of the lid member, making it easier to pour liquid from the container while maintaining a uniform appearance for the entire container.

The eighth invention is the seventh invention, in which the pouring lid preferably extends along the diagonal from the corner of the top plate where the spout is provided to the corner of the top plate opposite the corner in a plan view.

According to the eighth invention, the pouring lid extends along the diagonal of the rectangular outer shape of the body, so that the length of the pouring lid can be maximized while maintaining a uniform appearance for the entire container. Therefore, when a swing shaft is provided that extends in a direction perpendicular to the diagonal, it is possible to increase the opening of the pouring lid or reduce the force required to open the pouring lid depending on the position on the diagonal.

In the ninth invention, in the eighth invention, it is preferable that the pouring lid has a locking member for locking the liquid passage hole in a closed state.

According to the ninth invention, the locking member can prevent the pouring lid from opening accidentally, and the pouring lid can keep the liquid passage hole closed even when the container is turned on its side, so spillage of liquid contained in the container can be prevented in various states and positions. Furthermore, because the spout is provided at one corner and the pouring lid extends along a diagonal, space can be secured in the pouring lid for providing the locking member without affecting the outer shape of the body in a plan view.

The present invention provides a container that allows for efficient use of storage space.

In this embodiment, one of the diagonal directions of the square outer surface shape of the container body 20 and the lid member 30 of the container 1 in plan view shown in Figure 3 is the first direction x, and the other diagonal direction is the second direction y. In the first direction x in the plan view of Figure 3, the right direction is the +x direction, the left direction is the -x direction, and in the second direction y, the upward direction is the +y direction, and the downward direction is the -y direction. The direction from the container body 20 toward the lid member 30 is the +z direction (vertical upward direction), and the opposite direction is the -z direction (vertical downward direction), and the +z direction and the -z direction are collectively referred to as the third direction z. The first direction x, the second direction y, and the third direction z are mutually perpendicular.

The container 1 is for containing liquid and comprises a container body 20 having an opening 20a that opens upward, a lid member 30 that closes the opening 20a and is removably attached to the container body 20, and a first gasket 3 provided between the container body 20 and the lid member 30.

The container body 20 has a cylindrical body 21 with a bottom, a lid member attachment portion 22 provided on the upper portion of the body 21, and a covering portion 23 extending upward from the body 21.

In this embodiment, the body 21 of the container body 20 has an outer shape that is substantially square in plan view. However, the outer shape of the body 21 may be a shape other than a square as long as it is substantially rectangular. Furthermore, substantially rectangular also includes a square or rectangular shape with rounded corners, as shown in FIG. 3, etc.

The lid member attachment portion 22 extends inward from the upper end of the body portion 21 and has a flange portion 22a with an opening 20a, and a female screw 22b formed within the range of the planar shape of the body portion 21 in a plan view of the flange portion 22a. The female screw 22b is provided so as to surround the opening 20a of the flange portion 22a.

The covering portion 23 extends upward from the body portion 21 and covers the bulge portion 31c of the lid member 30 (described later) from the side, and has an outer shape that is substantially the same as the outer shape of the body portion 21 in a plan view.

In the container 1 according to this embodiment, the container body 20 is formed by joining two upper and lower members (reference numbers omitted). Specifically, the upper end of the body 21 is formed by the joint between the upper and lower members, while the flange portion 22a and the covering portion 23 are provided on the upper member.

The lid member 30 is made of synthetic resin and has a lower member 30a attached to the lid member attachment portion 22, an upper member 30b joined to the upper surface of the lower member 30a, and a pouring lid 37 attached to the upper member 30b so as to be swingable to open and close the liquid passage hole 32 provided in the lower member 30a and the upper member 30b.

The lower member 30a has a mounting portion 31 that is detachably attached to the lid member mounting portion 22, and a lower top plate 33a that is attached to the mounting portion 31 so as to close the opening 20a of the container body 20 when the mounting portion 31 is attached to the lid member mounting portion 22, and that has a lower liquid passage hole 32a for passing liquid.

The upper member 30b is joined to the upper surface of the lower top plate 33a to form a top plate 33 for closing the opening 20a of the container body 20 together with the lower top plate 33a, and has an upper top plate 33b provided with an upper liquid passage hole 32b that communicates with the lower liquid passage hole 32a, a spout 35 for pouring the liquid that has been drawn out through the lower liquid passage hole 32a and the upper liquid passage hole 32b (liquid passage hole 32), and a pair of guide walls 36 for guiding the liquid from the liquid passage hole 32 to the spout 35.

The lower top plate 33a has a square outer surface shape in a plan view. On the other hand, as shown in Figures 5 and 7, the upper top plate 33b has a shape that extends along a diagonal in the first direction x of the square outer surface shape of the lower top plate 33a and the body 21, and is joined by ultrasonic welding to a region on the upper surface of the lower top plate 33a that extends along the diagonal in the first direction x. In this way, the top plate 33 is formed by joining the lower top plate 33a and the upper top plate 33b, which have different planar shapes.

The mounting portion 31 has a cylindrical shape that extends downward (in the -z direction) from the top plate 33 and has an outer peripheral surface on which a male screw 31a is formed. The mounting portion 31 further extends upward from the threaded region 31b in which the male screw 31a is formed, and has a bulging portion 31c that bulges horizontally from the threaded region 31b so as to cover the extension portion 32d of the fluid passage hole 32 described later from the side. In this embodiment, the bulging portion 31c bulges in the -x direction from the threaded region 31b along the diagonal line in the first direction x of the square outer surface shape of the body portion 21 in a plan view. The mounting portion 31 also has a recess that is formed at the boundary between the threaded region 31b and the bulging portion 31c and has a downward pressing surface. With the first packing 3 attached in the recess, the male screw 31a and the female screw 22b are screwed together, and the first packing 3 is clamped between the pressing surface of the recess and the flange portion 22a.

In plan view, the top plate 33 has an outer surface shape that is substantially the same as the outer surface shape of the body 21. As shown in FIG. 7, the top plate 33 has a two-layer portion in which the lower top plate 33a and the upper top plate 33b are stacked in the center in the second direction y, and a single-layer portion of the lower top plate 33a extending from the two-layer portion to both sides in the second direction y. In the two-layer portion of the top plate 33, a lower liquid passage hole 32a and an upper liquid passage hole 32b are stacked to form a liquid passage hole 32 for passing liquid.

The fluid passage hole 32 has an overlapping portion 32c that overlaps with the internal space 31d of the screw forming region 31b of the mounting portion 31 in a plan view, and an extension portion 32d that extends from the overlapping portion 32c to an outer position of the internal space 31d in a plan view. The extension portion 32d extends in the first direction x.

Between the liquid passage hole 32 on the upper surface of the top plate 33 and the corner in the +x direction, an attachment portion 33c is provided to which the pouring lid 37 is attached so as to be able to swing. In addition, between the liquid passage hole 32 on the upper surface of the top plate 33 and the attachment portion 33c, an engagement portion 33d is provided with which a locking member 39 of the pouring lid 37, which will be described later, can engage.

The spout 35 is provided at the corner in the -x direction of the square outer surface shape of the top plate 33 in a plan view. The spout 35 rises up from the edge of the top plate 33 adjacent to the bulging direction of the bulging portion 31c. The spout 35 also has an inclined surface that slopes upward from the liquid passage hole 32 toward the edge.

The pair of guide walls 36 are arranged to face each other in the orthogonal direction (second direction y) perpendicular to the expanding direction (-x direction) of the bulging portion 31c with the liquid passage hole 32 between them, and are erected on the top plate 33 so as to extend from the liquid passage hole 32 to the spout 35 along the expanding direction. As shown in FIG. 7, the guide walls 36 in this embodiment are hollow.

The outer surface of one of the guide walls 36 facing away from the other guide wall 36 is substantially identical to a part of the outer surface shape of the body 21 in a plan view. In addition, the ends of the guide walls 36 in the -x direction are connected by the spout 35, and the outer surface of the connecting part facing away from the liquid passage hole 32 is also substantially identical to a part of the outer surface shape of the body 21 in a plan view. On the other hand, the ends of the guide walls 36 in the +x direction are spaced apart from each other and are used as an operating space for the pouring lid 37 described below.

The pouring lid 37 extends along a diagonal in the first direction x from the corner of the top plate 33 in the -x direction where the spout 35 is provided in a plan view to the opposite corner of the top plate 33 in the +x direction. The pouring lid 37 is attached to the top plate 33 between a pair of guide walls 36 so that it can swing around an axis extending in the second direction y.

Specifically, the pouring lid 37 has a swinging member 37b extending along the diagonal line between the guide walls 36, an attachment part 37a extending downward from the middle of the swinging member 37b and attached to the attachment part 33c so as to be swingable, a plug part 37c protruding downward from a position in the -x direction of the attachment part 37a on the swinging member 37b, a second packing 38 attached to the tip of the plug part 37c, and a locking member 39 for locking the pouring lid 37.

The swinging member 37b is attached to the mounting portion 33c of the top plate 33 so as to be swingable between a closed state (state shown in FIG. 4) in which the second packing 38 is clamped between the edge of the liquid passage hole 32 and the plug portion 37c, and an open state (state shown in FIG. 6) in which the second packing 38 is separated from the edge of the liquid passage hole 32. Specifically, the mounting portion 33c has an axis portion (reference number omitted) extending in the second direction y, and a support portion (reference number omitted) that supports the axis portion on the top plate 33. Meanwhile, the mounting portion 37a has an engagement portion that allows the axis portion of the mounting portion 33c to be rotatably engaged.

The locking member 39 has a second operating part 39a placed on the swinging member 37b, an insertion part 39b that extends from the second operating part 39a to the bottom of the swinging member 37b through a long hole (reference number omitted) that extends in the first direction x formed in the swinging member 37b, and an engagement part 39c that extends in the -x direction from the lower end of the insertion part 39b. The locking member 39 is attached to the swinging member 37b so as to be slidable in the first direction x between an unlocked position where the engagement part 39c is separated in the +x direction from an engagement hole extending in the first direction x of the engaged part 33d, and a locked position (position shown in FIG. 4) where the engagement part 39c is inserted into the engagement hole of the engaged part 33d.

(Action, Effect)
According to the container 1 of the first embodiment, the body 21 has an outer shape that is substantially square (rectangular). Therefore, by arranging multiple containers 1 so that the rectangular sides of each body 21 face each other, the gaps between the multiple containers 1 can be kept small, and the storage space can be used effectively.

In addition, in the container 1 according to this embodiment, the lid member attachment portion 22 has a female thread 22b, and the attachment portion 31 of the lid member 30 extends downward from the top plate 33 and has a male thread 31a. As a result, the portion of the attachment portion 31 that is screwed into the female thread 22b of the lid member attachment portion 22 is inserted into the container body 20 and is not exposed to the outside.

Therefore, by having the top plate 33 have an outer shape that is substantially the same as the outer shape of the body 21 in a plan view, the container 1 as a whole can have a unified appearance, and the appearance of the container 1 can be improved. Since there is no need to create a narrow space between the top plate 33 and the attachment portion 31 to achieve the above-mentioned unified appearance, the lid member 30 can also be easily cleaned.

In the container 1 according to this embodiment, the extension 32d of the liquid passage hole 32 allows the liquid passage hole 32 to be expanded to a position close to the spout 35, shortening the liquid path from the liquid passage hole 32 to the spout 35 and preventing liquid remaining on the top plate 33 from being unintentionally discharged when the container 1 is tilted, for example.

Since the bulge 31c has a diameter dimension larger than the threaded region 31b, it cannot be contained inside the female thread 22b and is exposed to the side. Here, in the container 1 according to this embodiment, the covering portion 23 is provided, so that the bulge 31c can be covered from the side while maintaining a sense of unity for the container 1 as a whole.

When the container 1 according to this embodiment is tilted so that the spout 35 faces downward, the liquid discharged from the liquid passage hole 32 can be reliably guided along the pair of guide walls 36 to the spout 35. Furthermore, the space between the pair of guide walls 36 can be used to attach the pouring lid 37 to the top plate 33 in a swingable state.

In addition, the corner of the top plate 33 where the spout 35 is provided is a sharp point in the planar shape of the lid member 30, making it easier to pour liquid from the container 1 while maintaining a unified appearance for the entire container 1.

Furthermore, because the pouring lid 37 extends along the diagonal of the square outer surface shape of the body 21, the length of the pouring lid 37 can be maximized while maintaining a uniform appearance for the entire container 1. Therefore, when the attachment portion 33c, i.e., the pivot axis of the pouring lid 37 that extends in a direction perpendicular to the diagonal, is provided, it is possible to increase the opening degree of the pouring lid 37 or reduce the force required to open the pouring lid 37 depending on the position on the diagonal. The opening degree of the pouring lid 37 here refers to the length H from the upper edge of the liquid passage hole 32 to the end of the stopper portion 37c of the pouring lid 37 on the spout 35 side when the pouring lid 37 is open as shown in Figure 6.

In the container 1 according to this embodiment, the locking member 39 prevents the pouring lid 37 from opening accidentally, and the pouring lid 37 can be kept closed even when the container 1 is turned on its side, preventing the liquid contained in the container 1 from spilling in various states and positions. Furthermore, because the spout 35 is provided at one corner and the pouring lid 37 extends along a diagonal, space for providing the locking member 39 can be secured in the pouring lid 37 without affecting the outer shape of the body 21 in a plan view.

Second Embodiment
In the container 1 of the first embodiment, the pouring lid 37 extends along a diagonal of the square outer surface shape of the body 21 in a plan view, but the extending direction of the pouring lid 37 is not limited to this. For example, in the container 1 of the second embodiment, the pouring lid 37 extends perpendicularly from one side of the square outer surface shape of the body 21 to the center of the square outer surface shape of the body 21 in a plan view.

Figure 8 is a plan view of the container 1 according to the second embodiment. Figure 9 is a cross-sectional view of the upper part of the container 1 when the dispensing lid 37 is open, taken along line IX-IX in Figure 8. In the following description, components that are substantially the same as those shown in Figures 1 to 6 are given the same reference numerals, and their description will be omitted.

In the second embodiment, the liquid passage hole 32 is provided on a line that passes through the center of the square outer shape of the body 21 in a plan view and is perpendicular to one side of the square. The spout 35 protrudes from the square outer shape of the body 21 in a plan view along a line perpendicular to the side of the square. The pouring lid 37 extends along a line perpendicular to the side of the square, and is provided so that the end of the pouring lid 37 fits the tip of the pouring spout 35.

The first embodiment is superior to the second embodiment in terms of the amount of liquid flowing out of the liquid passage hole 32, operability (operating force), and the appearance of the container 1.

Specifically, when the spout 35 of the container 1 according to the first embodiment and the container 1 according to the second embodiment are placed within the range of the outer shape of the body 21 in a plan view and the outer shape of the body 21 is made the same in a plan view, the pouring lid 37 of the container 1 according to the first embodiment can be made longer than the pouring lid 37 of the container 1 according to the second embodiment.

Therefore, when the length from the fitting portion of the mounting portion 37a of the pouring lid 37 to the end in the +x direction and the angle at which the pouring lid 37 is opened are the same between the container 1 according to the first embodiment and the container 1 according to the second embodiment, the length from the fitting portion of the mounting portion 37a to the end in the -x direction in the pouring lid 37 according to the first embodiment is longer than the length from the fitting portion of the mounting portion 37a to the end in the -x direction in the pouring lid 37 according to the second embodiment. Therefore, the opening degree H of the pouring lid 37 of the first embodiment shown in FIG. 6 is greater than the opening degree H of the pouring lid 37 of the second embodiment shown in FIG. 9.

In other words, when the container 1 as a whole has an excellent appearance that maintains a sense of uniformity in appearance, the container 1 according to the first embodiment can open the pouring lid 37 wider to increase the amount of liquid flowing out compared to the container 1 according to the second embodiment.

In addition, when the opening degree H of the pouring lid 37 is the same between the container 1 according to the first embodiment and the container 1 according to the second embodiment, the length from the attachment portion 37a of the pouring lid 37 to the end in the +x direction, i.e., the distance from the fulcrum of the pouring lid 37 to the point of force, can be made greater in the first embodiment, so that the first embodiment can provide better operability (operating force).
