Description

According to the present invention, the lid body is held at a predetermined opening angle with respect to the container body, and the container body does not fall down even if an external force is applied to the lid body in the direction of opening the lid body. and a lidded container in which only the lid body is further opened to prevent the container body from overturning.

Containers such as accessory containers, medicine containers, and tool boxes generally have a length of 250-350 mm, a depth of 180-280 mm, and a height of 80-250 mm, and containers with lids are often used. The lid is usually connected to the container body by a known hinge, and the lid is connected to the container body even when the lid is open.

In such a container with a lid, when the lid is opened, the lid opens 180 degrees or more with respect to the opening surface of the container body, and the lid is 90 degrees or more with respect to the opening surface of the fully open container and the container body. A partially open container that opens about 120 degrees is known. The fully open container is easy to take out when taking out the contents of the container body, but it has the disadvantage of taking up a lot of space. Therefore, a partially open container is often used for medicine containers and the like that are used in a limited space in a room because they do not take up much space.

JP 2003-226345 A

However, in the case of a partially opened container, the lid is upright, so that the elbow of the operator hits the lid unexpectedly, and the lid may topple over. If the lid falls in the direction of closing the opening of the container body, there is no big problem, but if the lid falls further in the direction of opening, the container body may be overturned. Therefore, in the case of a partially opened container, there is a demand for the development of a container with a lid that can hold the lid while maintaining a predetermined opening angle and that does not overturn the container body even if an external force is applied in the direction of further opening the lid. It has been demanded.

Japanese Unexamined Patent Application Publication No. 2003-226345 discloses a hinge-type opening/closing container comprising a container body and a lid rotatably hinged to the container body, wherein the lid is provided at a plurality of locations on the container body. and each of the hinge portions provided on the lid has grooves formed along the periphery of the hinge portions, while the container body is provided with these grooves on the hinge side portion of the container body. each of which has a plurality of tongues corresponding to each other, and each of these tongues is a hinge beyond the edge of the groove in the rotation direction without interfering with the groove when the lid is rotated. A hinged closure is disclosed that presses around the body. The hinge-type openable/closable container disclosed in Japanese Patent Laid-Open No. 2003-226345 is a fully openable container in which the lid body is fully opened, and the lid body, which holds a predetermined opening angle, is prevented from rotating by its own weight in a direction to close the opening of the container body. However, it does not assume the case where an external force acts in the direction of further opening the lid that is held at a predetermined opening angle.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to enable a partially open container to hold a lid body at a predetermined opening angle, and to prevent the container body from overturning even when an external force is applied in the direction of further opening the lid body. To provide a container with a lid.

That is, the present invention solves the above-described conventional problems by providing a container body, a lid attached to the container body by means of a hinge so as to be freely opened and closed, and a rear plate of the container body which is opened when the lid is opened. and a thin plate-like piece attached to the lid that abuts on the outer surface of the lid and holds the lid at a predetermined opening angle.

The present invention also provides the lidded container, wherein the predetermined opening angle is an inner angle formed by the opening surface of the container body and the lid, and is 90 to 120 degrees. It is.

Further, the present invention provides the lidded container, wherein the outer surface portion of the rear side plate with which the thin plate-like piece abuts is a vertical surface or a small projection.

Further, according to the present invention, the outer surface of the rear plate is a vertical surface, and the holding of the predetermined opening angle of the lid is achieved by matching the tip angle of the outer surface side of the thin plate piece with the vertical surface of the rear plate. The object is to provide the container with lid characterized by contact.

Further, according to the present invention, the outer surface portion of the rear side plate is a small projection, and the retention of the predetermined opening angle of the lid is achieved by the tip angle of the inner side surface of the thin plate-like piece and the small projection of the rear side plate. The object is to provide the container with lid characterized by contact.

Further, according to the present invention, the contact between the thin plate-like piece and the outer surface portion of the rear side plate is such that the contact is released when the cover is further rotated by hand from a predetermined holding state in the direction of opening the cover. and when the lid body is closed in a fully open state with a predetermined opening angle or more, the thin plate-like piece and the outer surface portion of the rear side plate do not come into contact with each other, and the lid body is closed without stopping. The lidded container is provided as described above.

Further, according to the present invention, the thin plate-like piece extends outward from the axis of the hinge from a position above the axis of the hinge of the rear side plate of the lid body and is bent downward in the direction of rotation of the hinge. The lidded container is characterized in that it is extremely flexible.

Further, in the present invention, the contact between the thin plate-like piece and the outer surface of the rear plate is such that the outer angle formed by the thin plate-like piece and the vertical plane of the rear plate in a longitudinal section passing through the contact point is 80±. It provides the lidded container characterized by 5 degrees

According to the present invention, since the lid is held at a predetermined opening angle with respect to the container body, the work is easy. Moreover, even if an external force is applied to the lid body in a direction to open the lid body against its will, only the lid body is further opened to prevent the container body from overturning. Also, when the cover is closed from the fully open state, even if the tip of the thin plate-like piece slightly hits the side surface of the rear side plate, the cover is flexed. Therefore, it is convenient for a medication container that is used in a limited space in a room.

Next, a lidded container according to an embodiment of the present invention will be described with reference to FIGS. 1 to 10. FIG. A lidded container 10 has a container body 1 and a lid body 2 attached to the container body 1 by means of a hinge 3 so as to be freely opened and closed. In the present invention, the lidded container is preferably a container that can be carried around, and examples thereof include a container for small items, a container for administering medication, and a tool box. A drug-administering container is a container containing a plurality of containers that individually store pharmaceuticals to be administered to inpatients and the like for each patient and date.

In the lidded container 10, the container body 1 is a box-shaped container having a bottom plate 11a and four side plates 11, 12, 12, 13 and no top plate. The lid 2 has a top plate 21a and four side plates 21, 22, 22 and 23, and does not have a bottom plate.

In the lidded container 10, the hinge 3 that connects the container body 1 and the lid 2 includes a pair of left and right first support portions 14, 14 having shaft holes 141, 141 as shown in FIG. A hinge 3 having a pair of left and right second support portions 6, 6 having axial projections 31, 31 that are rotatably fitted can be mentioned. That is, in this example, as shown in FIG. 4, the first support portions 14, 14 face the upper portion of the outer surface of the rear plate 13 of the container body and are separated from each other by a predetermined distance in the longitudinal direction of the rear plate 13. It is a pair of plate-like bodies attached as follows. The shaft holes 141 , 141 are formed through the rear side plate 13 in the longitudinal direction above the first support portions 14 , 14 . The second support parts 6, 6 are a pair of plate-like bodies attached to the lower part of the outer surface of the rear plate 23 of the lid body 2 so as to face each other with a predetermined distance in the longitudinal direction of the rear plate 23. be. The shaft projections 31 , 31 are formed as cylindrical projections extending short in the longitudinal direction of the rear side plate 13 at the lower portions of the second support portions 6 , 6 . The inner dimensions of the first supporting parts 14, 14 are substantially the same as or slightly larger than the outer dimensions of the second supporting parts 6, 6. The hinges 3 are provided at two locations on the lidded container 10 with a predetermined distance therebetween in the longitudinal direction of the rear side plates 13 and 23 . Thereby, in the lidded container 10 , the lid 2 can be opened to one side with respect to the container body 1 .

In the lidded container 10 , a portion (outer surface portion) of the rear plate 13 of the container main body 1 with which the front end of the thin plate-like piece 4 abuts is a minute projection 5 slightly protruding from the surface of the rear plate 13 . That is, the minute protrusion 5 has a vertical surface (tip surface) in a side view. The projection height of the minute projections 5 is appropriately determined according to the shape of the thin plate-like piece 4 . Further, in the present invention, the minute projections 5 may be absent. In this case, the position of the center of the link shaft and the length of the thin plate-like piece 4 may be appropriately determined.

A hinge axis center 31 of the hinge 3 is located outside the vertical plane of the minute protrusion ₅ by a length h2. Further, the hinge axis center 31 is formed near the upper end of the container body 1 . As a result, the lid 2 can cover the container body 1, and slight contact between the thin plate-like piece 4 of the lid 2 and the microprojection surface can be achieved.

In the lidded container 10 , a thin plate-like piece 4 is formed near the hinge 3 of the rear side plate 23 of the lid 2 . The thin plate-like piece 4 is formed between the second support portions 6, 6 of the lid 2 in this example. By forming the thin plate-like piece 4 in the vicinity of the hinge portion, slight contact between the thin plate-like piece 4 and the outer surface portion (vertical surface of the minute projections) of the rear side plate of the container body 1 can be realized. Slight contact means that although there is a supporting force to support the partially opened cover 2, if an external force further acts on the cover 2 in the opening direction, the partially opened cover 2 cannot be supported and opens further. To tell. The thin plate-like piece 4 is composed of a horizontal portion 41 extending outward from the axis 31 of the hinge 3 from the rear plate 23 above the axis 31 of the hinge of the lid 2 in a side view, and a vertical portion 42 bending downward. It has a substantially J-shape in which the axis 31 of the hinge is located inside. Therefore, the distal end of the vertical portion 42 of the thin plate-like piece 4 has flexibility to bend inward in the direction of rotation of the hinge, especially in response to an external force. It is preferable that the thin plate-like piece 4 is made of resin because the strength of contact with the rear plate of the container body can be easily controlled.

The thickness of the vertical portion 42 of the thin plate-like piece 4 is not particularly limited, but is appropriately determined, for example, between 0.5 mm and 3 mm. The thickness of the vertical portion 42 of the thin plate-like piece 4 is not limited to a uniform thickness, and may have a non-uniform thickness that tapers toward the tip. The vertical portion 42 of the thin plate-like piece 4 is a tongue piece extending vertically with the tip facing downward when the lid body 2 is closed. That is, the vertical portion 42 of the thin plate-like piece ₄ is separated from the axis 31 of the hinge in the horizontal direction by h3. The dimension h3 is ₃ to 7 mm. If the dimension _h3 is too small, the thin plate-like piece 4 will not come into contact with the rear side plate of the container body 1, and if it is too large, the projection from the lid body 2 will become large and the usability of the lidded container 10 will be poor. As a result, the minute projections 5 of the container body 1 are formed in the vicinity of the position h3 downward from the axis ₃₁ of the hinge.

Further, the tip of the vertical portion 42 of the thin plate-like piece ₄ is spaced h1 downward from the axis 31 of the hinge. If the dimension h1 is too small, the thin plate-like piece 4 will not come into contact with the rear side plate of the container body ₁ , and if it is too large, the projection from the lid body 2 will become large and the usability of the lidded container 10 will be poor. The dimension h ₁ and the dimension h ₂ are almost the same, or the dimension h ₁ is about 0.01 to 1 mm smaller than the dimension h ₂ . As a result, slight contact between the thin plate-like piece 4 and the rear plate of the container body 1 (the vertical surface of the minute projections) can be realized.

In the lidded container 10, when the lid 2 is opened, the tip of the thin plate-like piece 4 and the outer side portion of the rear side plate 13 of the container body 1 abut to hold the lid 2 at a predetermined opening angle. The predetermined opening angle is an inner angle (α) formed by the opening surface of the container body 1 and the lid 2, and is 90 to 120 degrees. Thereby, when using the lidded container 10, the opening is not opened too much and space is not taken. Further, the lid 2 is held at a predetermined opening angle by the contact between the tip angle (corner) 44 on the outer surface side of the thin plate-like piece 4 and the outer surface portion of the rear plate 13 (in this example, the vertical surface of the minute protrusions). things are preferred. As a result, the tip of the thin plate-like piece 4 and the outer surface of the rear plate 13 of the container body 1 are in contact with each other with a small support force that supports the weight of the lid 2 in a substantially vertical position. That is, the contact between the thin plate-like piece 4 and the outer surface of the rear side plate 13 has a contact strength such that the contact is released when a pushing force such as a hand acts further in the direction of opening the lid body 2 from the predetermined holding state. is. As a result, even if an external force (for example, an operator's elbow) acts in the direction of further opening the lid 2, the lid 2 falls in the opening direction, so that the container body 1 does not overturn. In this way, a small contact of the tip of the thin plate piece 4 against the container body 1 has a supporting force to support the weight of the lid 2, and is a supporting force smaller than a larger acting force. This is because the flexible thin plate-like piece 4 that bends inward is formed, so that the vertical portion 42 of the thin plate-like piece 4 (in FIG. ) is difficult to bend outward, it stops at the abutting position by supporting the weight of the lid 2 itself.

On the other hand, when closing the lid body 2 in the fully open state in which the tip 43 of the thin plate-like piece 4 and the outer surface of the rear plate 13 abut at a predetermined opening angle or more, the side surface of the thin plate-like piece 4 and the rear plate 13 The lid closes without stopping in contact (Fig. 10). This is probably because, as shown in FIG. 10, the leading end of the vertical portion 42 of the thin plate-like piece 4 (which lies horizontally in FIG. 9) tends to bend inward with respect to rotation in the Y direction.

In the lidded container 10, the contact between the thin plate piece 4 and the side surface of the rear plate 13 is such that the outer angle (β) formed by the thin plate piece and the side surface of the rear plate is 80±5 in a longitudinal section passing through the contact point. degrees, preferably 80±2 degrees (see FIG. 6). If the outer angle (β) formed by the thin plate-like piece and the side surface of the rear side plate is too large, the lid 2 can be held at the predetermined opening angle, but the supporting force is too strong, and the lid 2 cannot be opened further. When an external force (for example, an operator's elbow) acts in the opening direction, the lid body 2 does not fall down in the opening direction, and the container body 1 falls over. On the other hand, if the outer angle (β) formed by the thin plate-like piece and the side surface of the rear side plate is too small, the weight of the lid 2 cannot be supported, and the lid 2 cannot be held at a predetermined opening angle. .

Next, how to use the lidded container 10 will be described. When the lidded container 10 is not in use, the lid 2 remains closed as shown in FIG. 1 (FIGS. 1 and 5). If the lidded container 10 has a handle, it can be carried. Next, the lid body 2 is opened when taking out the contents stored in the lidded container 10 and performing work or the like. The lid 2 is connected to the container body 1 by a hinge, and the lid 2 opens smoothly. , the lid body 2 is held in that posture at a predetermined opening angle (90 degrees to 120 degrees). This is because the tip 43 of the thin plate-like piece 4 of the lid 2 hits the vertical surface of the minute projections of the rear plate 13 of the container body 1 (FIGS. 2 and 6). The contact between the thin plate piece 4 and the side surface (outer surface portion) of the rear plate 13 is such that the outer angle (β) formed by the thin plate piece and the side surface of the rear plate is 80±5 degrees in a longitudinal section passing through the contact point. be. Also, since this contact area is small, it is sufficient to support the weight of the partially open lid body 2 . The lidded container 10 in the half-opened state is in a used state. is.

In this lidded container 10 in the half-opened state, when, for example, the worker's elbow hits the lid 2 during work and a force acts in the direction of opening the lid 2, the contact force between the side surface of the thin plate-like piece 4 and the rear side plate 13 is released, and the lid body 2 rotates in the opening direction with respect to the container body 1 . In other words, the tip of the thin plate-like piece 4 cannot be completely bent by the external force, and the rigidity is superior, so that the contact is lost. Then, since the second support portions 6, 6 of the lid body 2 abut against the protrusions 8 of the container body 1, the lid body 2 is opened substantially 180 degrees and stops. In this way, even if an unintended external force acts on the lid 2, the container body 1 will not overturn.

Next, the lidded container 10 in the fully opened state is returned to the state when it is not in use. That is, the lid 2 of the lidded container 10 in the fully open state is closed. At this time, even if the lid body 2 comes to the predetermined opening angle position when the lid body 2 is opened, the thin plate-like piece 4 and the side surface of the rear side plate 13 touch each other very slightly, but only rub against each other, and there is almost no resistance. , the opening of the container body 1 can be closed with the lid 2 (FIGS. 8 and 10). This is because, as shown in FIG. 10, the tip of the vertical portion 42 of the thin plate-like piece 4 (which lies horizontally in FIG. 9) tends to bend inward with respect to the rotation in the Y direction. Even if the side surface of the rear side plate 13 comes into contact with it, it slides to the extent that it is rubbed, and the lid body 2 can be closed without resistance.

According to the lidded container 10, the lid 2 is held at a predetermined opening angle with respect to the container body 1, and an external force acts on the lid 2 in the direction of opening the lid 2, contrary to the intention. However, the container body 1 does not fall down, and only the lid body 2 is further opened to prevent the container body from falling down. Moreover, when closing the lid body 2 in the fully open state, it can be closed without going through the holding state on the way.

Next, another embodiment of the present invention will be described with reference to FIGS. 11 and 12. FIG. In FIGS. 11 and 12, the same components as those in FIGS. 1 to 10 are denoted by the same reference numerals, and descriptions thereof are omitted, and different points are mainly described. That is, the lidded container 10a of FIGS. 11 and 12 differs from the lidded container 10 of FIGS. 1 to 10 in that the outer surface portion of the rear side plate 13 of the container body 1 is provided with small protrusions 5a. That is, the height of the small projections 5a on the rear plate 13 of the container body 1 of the lidded container 10a is slightly lowered to form the vertical surface of the rear plate 13 of the container body 1 of the lidded container 10, A small projection 5a having a height of about 1 to 3 mm is formed on the upper edge of the minute projection which is rectangular in side view. The small projection 51a has an outwardly upward inclined surface 51a at its lower portion in a side view (see FIG. 12).

In the lidded container 10a, the engaging relationship between the tip 43 of the thin plate-like piece 4 of the lid 2 and the small projection 5a is as follows. That is, the lid body 2 is opened when taking out the contents stored in the lidded container 10a and performing work or the like. The lid 2 is connected to the container body 1 by a hinge, and the lid 2 opens smoothly. , the lid body 2 is held in that posture at a predetermined opening angle (90 degrees to 120 degrees). This is because the tip 43a on the inner surface side of the thin plate-like piece 4 of the lid 2 hits the small protrusion 5a and the inclined surface 51a of the rear plate 13 of the container body 1 (FIG. 12). Since this contact is small, it is sufficient to support the weight of the partially opened lid body 2 . The lidded container 10a in the half-opened state is in a used state. is.

Next, the lidded container 10a in the fully open state is returned to the state when it is not in use. That is, the lid body 2 of the lidded container 10a in the fully open state is closed. At this time, even if the lid body 2 comes to the predetermined opening angle position when the lid body 2 is opened, the thin plate-like piece 4 and the small projection 5a on the outer surface of the rear side plate 13 touch each other very slightly, but only rub against each other. Therefore, the opening of the container body 1 can be closed with the lid 2 with almost no resistance. This is because the tip of the vertical portion 42 of the thin plate-like piece 4 is likely to bend inward with respect to rotation in the Y direction. The lid 2 can be closed.

In the present invention, the structure and shape of the container main body or the lid are not limited to the above-described embodiments, and examples thereof include elliptical containers, circular containers, irregularly shaped containers, and the like. Further, the minute protrusions on the container body can be omitted, and the thin plate-like piece 4 can directly hit the side surface of the rear side plate 13 . Moreover, the vertical surface, which is the tip surface of the microprotrusions of the container body 1, is not required to be strictly vertical, and may be a slightly inclined side surface.

According to the present invention, the lid is held at a predetermined opening angle with respect to the container body during use. Even if an external force is applied to the half-open lid body in the direction of opening the lid body against intention, the container body 1 does not fall down, and only the lid body 2 is further opened to prevent the container body from falling down. In addition, when closing the lid body 2 in the fully open state, the lid body 2 can be closed almost smoothly without going through the holding state on the way. Therefore, if a container with a lid is used as a container for administering medicine, for example, there is no concern that the container body will tip over even in a narrow space, and work can be carried out with peace of mind.
