Description

[0001]
BACKGROUND OF THE INVENTION
The present invention does not require a spring piece or the like that forms a gap or the like in the special lid body, has a good appearance, can prevent clogging due to the extract, and has a cap when the lid body is closed. The present invention relates to a cap in which the inside of the main body is not directly communicated with the outside.
[0002]
[Prior art]
Conventionally, various containers, particularly tube containers, have been known that can be placed upside down, and in this way, rather than laying the container aside. Even has the advantage of not taking up space. The cap adopted for such a container is roughly the upper part of the container body, a cap body that surrounds the periphery of the extraction port, a lid that closes the extraction port of the container body so as to be openable and closable, and the lid is the cap body. And a hinge that is pivotably connected, and the container body can be supported in an inverted state by placing the cap on the placing surface with the container body turned upside down.
[0003]
However, if you use such a container in a bathroom such as a washroom or bathroom, and leave it upside down after use, the water adhering to the container body will flow down the surface and flow down the container. There was a problem in that it flowed from between the main body and the cap main body placed on the main body and accumulated in the cap main body. For the purpose of solving such problems, for example, Patent Documents 1 to 3 disclose caps having a structure that allows water that flows into the cap body from between the container body and the outside to flow out from the lid body side.
[0004]
In Patent Document 1, a cap body of a three-point hinge-type elastic reversal cap includes a small-diameter mounting peripheral wall, a large-diameter design peripheral wall, and a top wall that is located between the peripheral walls and in which an extraction hole is formed. In addition, a small hole is formed in the top wall portion, and the water that has entered the cap body through the small hole through the gap on both sides of the elastic reversal plate of the canopy is discharged to the outside.
[0005]
In Patent Document 2, a cap body is composed of a top plate, an inner cylinder, and an outer cylinder, and a lid body is connected to the cap body through a reversing hinge including a pair of left and right coupling pieces and a substantially L-shaped spring piece. In addition, a notch hole is provided in the upper peripheral wall portion of the outer cylinder between the connecting pieces of the reversing hinge, and a gap communicated with the notch hole between the left and right edges of the spring piece and the lid when the lid is closed. Is provided.
[0006]
In Patent Document 3, a cap body and an upper lid are provided, the cap body is composed of a top plate, an inner cylinder and an outer cylinder, and a drain hole is provided near the top plate of the outer cylinder, and a drain hole is provided on the outer surface of the upper lid. A subsequent drainage guideway is provided, and this drainage guideway extends toward the ground contact surface when the container of the upper lid is inverted.
[0007]

Japanese Utility Model Laid-Open No. 5-72747 [Patent Document 2]
Japanese Utility Model Publication No. 6-18263 [Patent Document 3]
Japanese Patent Laid-Open No. 2001-48203
[Problems to be solved by the invention]
By the way, in the above-mentioned Patent Document 1, since a small hole is formed in the top wall portion, when the canopy is opened, a small hole is seen adjacent to the extraction hole in the top wall portion, In addition to being unfavorable, there is a problem that the extract may clog the small holes when the extract is wiped from the extraction holes. Further, in Patent Document 2, since the cutout hole is formed in the form in which the outer cylinder communicates directly with the outside, when the lid is opened, the lid is closed when not in use. Even, there is a problem that water may flow directly into the outer cylinder through the cutout hole.
[0009]
Further, in these Patent Documents 1 and 2, for drainage, gaps on both sides of the elastic reversal plate and gaps between the left and right side edges of the spring piece and the lid are used. Therefore, the formation of these spring pieces and the like is indispensable, and the structure cannot be applied to a cap that does not include them.
[0010]
On the other hand, Patent Document 3 is capable of discharging water from the inside of the cap body to the outside without providing the elastic reversal plate or the like, but forms a drain hole that directly communicates with the inside of the outer cylinder. Therefore, as in Patent Document 2, there is a problem that this drain hole becomes an inflow path through which water flows directly into the outer cylinder. In addition, since the drainage guide path is formed on the outer surface of the upper lid, there is a problem that it is not preferable in appearance.
[0011]
The present invention was devised in view of the above-described conventional problems, and it is not necessary to provide a spring piece or the like that forms a gap or the like in the special lid body, and the appearance is good, and clogging due to the extract is also caused. An object of the present invention is to provide a cap that can be prevented and that does not allow the inside of the cap body to communicate directly with the outside when the lid is closed.
[0012]
[Means for Solving the Problems]
The cap according to the present invention includes a cap body that is placed on an upper portion of the container body so as to surround the periphery of the extraction port, a lid that closes the extraction port of the container body so as to be openable and closable, and the lid is rotated to the cap body A hinge that freely connects to the cap body and supports the container body in an inverted state while allowing water flowing into the cap body to flow out from between the container body and the hinge. A hinge block that protrudes outward from the cap body, and is formed to protrude outward from the lid and is foldably connected to the hinge block of the body. A lid-side hinge block abutting against the body-side hinge block with the extraction port closed, and between the body-side hinge block and the lid-side hinge block One end inside the cap body and the other end communicated was formed with the outside through the water flow hole.
[0013]
In the present invention, the inside and outside of the cap body are communicated with each other through a water flow hole formed between the body-side hinge block and the lid-side hinge block that project outward from the cap body and the lid body. In addition, since the water flow hole is formed in the hinge block in this way, there is no need to provide a spring piece or the like that forms a gap or the like in the lid, and of course when the lid is closed, It is not noticeable even when opened, and it is possible to obtain a good appearance, and it is possible to reduce the possibility that the extract will reach the flow hole by wiping the extract from the extraction port. It is possible to prevent the pores from being clogged with the extract.
[0014]
Further, when the extraction port is closed by the lid, the lid side hinge block is brought into contact with the body side hinge block, and the inside of the cap body is communicated with the outside only through the water flow hole. While the body is closed, the inside of the cap body can be directly communicated with the outside to prevent water from flowing into the cap body.
[0015]
Moreover, one end of the water flow hole is a through-hole portion that passes through the body-side hinge block and opens toward the inside of the cap body. The inside of the cap body is completely cut off from the outside by the through-hole when the container body is inverted, so that the body-side hinge block located above the lid-side hinge block is infiltrated from the outside. Can be more reliably prevented.
[0016]
Furthermore, the other end of the water flow hole is formed by closing a groove formed in one of the main body side hinge block and the lid side hinge block with the other. The other end of the water flow hole is composed of a groove formed on one of the main body side hinge block and the lid side hinge block that are foldably connected to each other, so that it is exposed when the lid is opened. This groove portion can be cleaned, and the clogging of the water flow holes can be more reliably prevented.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of a cap according to the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the cap 1 according to this embodiment mainly includes an upper cap body 4 such as a tube container, and a cap main body 4 that covers the periphery of the extraction port 3 of the main container body 2. A lid body 5 that closes the extraction port 3 of the container body 2 so as to be openable and closable and a hinge 6 that pivotably connects the lid body 5 to the cap body 4 are integrally formed of a synthetic resin material.
[0018]
The container body 2 has a cylindrical body 7 for containing the extract, and a shoulder 8 formed on the body 7 in a cone shape by gradually reducing the diameter from the outer diameter of the body 7. And a neck portion 9 formed on the shoulder portion 8 and having an extraction port 3 for taking out the extract therein.
[0019]
The cap body 4 is suspended so as to surround the periphery of the neck 9 from the top plate 10 disposed on the neck 9 and the lower surface of the top plate 10, and via the locking portion 11 formed between the neck 9 and the cap body 4. The inner cylinder part 12 to be locked and the outer cylinder part 13 that hangs down from the outer peripheral edge of the top plate 10 on the outer side of the inner cylinder part 12 toward the shoulder part 8 and serves as an exterior body of the cap 1 are configured. At the center portion of the top plate 10, there are formed an insertion portion 14 that protrudes from the lower surface and press-contacts to the inner periphery of the extraction port 3, and a protruding portion 15 that protrudes from the upper surface thereof. The extraction hole 16 is formed across the insertion part 14.
[0020]
The cap body 4 is formed by engaging the inner tube portion 12 with the neck portion 9 while inserting the insertion portion 14 into the extraction port 3 so that the extraction hole portion 16 communicates with the extraction port 3. A cylindrical portion 13 or the like surrounds the periphery of the extraction port 3 so as to cover the upper portion of the container main body 2.
[0021]
The lid body 5 is formed in a dish-like shape as a whole from a top plate 17 having an outer contour that matches the outer contour of the top plate 10 and an annular peripheral wall 18 that is formed by hanging from the outer periphery of the top plate 17. Is done. At the center of the top plate 17, a plug body 19 is formed so as to protrude from the extraction hole 16 so as to be able to be inserted and removed.
[0022]
The plug body 19 is formed in a hollow shaft shape so as to be elastically deformable, and an annular protrusion 20 is formed around the plug body 19. The annular protrusion 20 is detachably engaged with the stepped portion 22 in the extraction hole portion 16 while entering the inside while being deformed flexibly, whereby the extraction hole portion 16 and thus the extraction portion are extracted. The mouth 3 is liquid-tightly closed by the plug body 19, and the annular peripheral wall 18 of the lid body 5 is superimposed on the top plate 10 of the cap body 4.
[0023]
The hinge 6 includes a main body side hinge block 23 and a lid side hinge block 24. In particular, the main body side hinge block 23 is formed to protrude outwardly from the outer cylindrical portion 13 of the cap main body 4, and the lid side hinge block 24 is also formed on the annular peripheral wall 18 of the lid body 5. It is formed so as to protrude outward from this. In the illustrated example, the hinge blocks 23 and 24 are both formed in a triangular prism shape, the pair of top surfaces 23a and 24a are laterally arranged, and one of the three side surfaces is the outer cylindrical portion 13 and the annular shape, respectively. It becomes a joint surface with the peripheral wall 18, and one side faces each other in the vertical direction, and further, one side faces are inclined surfaces 23b and 24b projecting outward.
[0024]
The body-side hinge block 23 and the lid-side hinge block 24 are in liquid-tight contact with each other in a state where the lid 5 is overlaid on the cap body 4 and the extraction port 3 is closed with the lid 5. In the illustrated example, one of the side surfaces of the main body side hinge block 23 and the lid side hinge block 24 is respectively in contact with the upper end surface of the outer cylindrical portion 13 and the lower end surface of the annular peripheral wall 18. 24c, and the main body side hinge block 23 and the lid side hinge block 24 are in liquid-tight contact with each other by the contact surfaces 23c and 24c. Further, the main body side hinge block 23 and the lid side hinge block 24 are connected to each other at the outer ends of the contact surfaces 23c, 24c so as to be foldable to each other, whereby the cover body 5 is rotatably connected to the cap body 4.
[0025]
Furthermore, between the main body side hinge block 23 and the lid side hinge block 24, a water flow hole 25 is formed in which one end communicates with the inside of the outer cylinder portion and the other end communicates with the outside. In this embodiment, the water flow hole 25 is formed through the through-hole portion 26 formed through the main body side hinge block 23 and the lid-side hinge block 24 and communicated with the through-hole portion 26. And a communication hole portion 27.
[0026]
The through-hole portion 26 forms one end of the water flow hole 25, and passes through the outer cylinder portion 13 from the contact surface 23 c of the main body side hinge block 23 along the inclined surface 23 b and opens toward the inside of the cap main body 4. Is done. The communication hole portion 27 forms the other end of the water flow hole 25 and penetrates the lid side hinge block 24 upward from the contact surface 24c of the lid side hinge block 24 so that the lid side hinge block 24 is inclined. Opened in the surface 24b. The flowing water hole 25 is configured such that the contact surfaces 23c and 24c of the hinge blocks 23 and 24 are in liquid-tight contact with each other so that the through-hole portion 26 and the communication hole portion 27 are connected in series. Thus, the inside of the outer cylinder portion 13 of the cap body 4 is communicated with the outside.
[0027]
The container body 2 is placed upside down by being supported upside down by the cap 1 by placing the cap 1 upside down and placing the cap 1, specifically the top plate 17 of the lid 5 on the mounting surface. It is like that. The cap body 4 and the lid body 5 are formed with a recess 28 that serves as a clue when opening the lid body 5 and a finger hook portion 29 that projects in a hook shape on the opposite side of the hinge 6. The
[0028]
The operation of the cap 1 according to this embodiment will be described. When the container body 2 is placed upside down with the cap 1 down when not in use, the water adhering to the container body 2 flows down as shown in FIG. 3, and the shoulder 8 of the container body 2 and the cap body 4 flows into the inside of the cap body 4 from the gap between the outer cylinder portion 13 and the outer cylinder portion 13. The flowing water reaches the through hole portion 26 of the main body side hinge block 23 that is opened to the outer tube portion 13 through the outer tube portion 13 and the inner tube portion 12 of the cap body 4 and the top plate 10. When reaching the through hole portion 26 of the main body side hinge block 23, the water further flows down through the through hole portion 26.
[0029]
Since the lid hinge block 24 is in liquid-tight contact with the main body side hinge block 23 via both contact surfaces 23c, 24c, the water flowing down the through hole portion 26 of the main body side hinge block 23 is prevented. Further flows into the communication hole 27 of the lid-side hinge block 24 and flows down. And the water which flowed into the communicating hole part 27 of the lid side hinge block 24 will flow out outside as it is, and it can prevent that water accumulates inside the cap main body 4 by this.
[0030]
On the other hand, when extracting the extract from the container body 2, the lid body 5 is rotated with respect to the cap body 4 via the hinge 6 as usual, and the plug body 19 is extracted from the extraction hole 16 and opened. The extract can be taken out from the extraction port 3 through the extraction hole 16, and after the removal, the upper surface of the top plate 10 around the extraction hole 16 is wiped, and then the lid 5 is rotated to move the top of the cap body 4. As a result, the extraction hole 16 is closed by the plug 19 and the hinge blocks 23 and 24 are brought into contact with each other to form a series of water holes 25.
[0031]
In the cap 1 according to the present embodiment described above, the main body side hinge block 23 and the lid side hinge block 24 in which the inside and the outside of the cap body 4 are formed to protrude outward from the cap body 4 and the lid body 5 respectively. Since the water flow hole 25 is formed in the hinge blocks 23 and 24 in this way, it is necessary to provide a spring piece or the like that forms a gap or the like in the lid body 5. It can be applied to various types of caps 1 and can be applied to various types of caps 1, not only when the lid 5 is closed, but also when it is opened, so that a good appearance can be obtained. When the extract is wiped from the extraction hole 16 on the top plate 10, the possibility that the extract reaches the flowing water hole 25 can be reduced, and the flowing water hole 25 is clogged with the extract. It is possible to prevent the Rukoto.
[0032]
Further, when the extraction port 3 is closed by the lid 5, the lid-side hinge block 24 is brought into liquid-tight contact with the main body-side hinge block 23, and the inside of the outer cylinder portion 13 has a flow hole 25. Since the structure communicates with the outside only through the inside, the inside of the outer cylindrical portion 13 can be directly communicated with the outside while the lid 5 is closed, and water can be prevented from flowing into the outside.
[0033]
In particular, the inside of the outer cylinder portion 13 is formed by forming one end of the water flow hole 25 penetrating the main body side hinge block 23 and opening toward the inside of the outer cylinder portion 13 as a through hole portion 26 having a considerable length. When the container body 2 is turned upside down, the main body side hinge block 23 located above the lid side hinge block 24 is completely blocked from the outside, so that water can be further prevented from entering from the outside. Can do. Moreover, formation of the water flow hole 25 to the hinge blocks 23 and 24 can also be utilized as a meat escape on resin molding.
[0034]
FIG. 4 shows a modification of the above embodiment. In this modified example, a belt-like elastic piece constituting a so-called snap hinge, with a pair on both sides of the hinge 6 and one end connected to the outer surface of the outer cylindrical portion 13 and the other end connected to the outer surface of the annular peripheral wall 18. 30 is provided. Therefore, even if the flowing water hole 25 is formed in the hinge 6, the cap 1 can be configured as a snap hinge cap similar to those of Patent Documents 1 and 2 by adding the elastic piece 30. Even in such a modification, it is a matter of course that the same operations and effects as those of the above-described embodiment can be obtained.
[0035]
5 to 8 show other embodiments. In the embodiment shown in FIG. 5 and FIG. 6, the communication hole 27 penetrates the lid-side hinge block 24 upward from the contact surface 24 c of the lid-side hinge block 24, and the lid-side hinge block 24 is inclined. Instead of the form opened on the surface 24b, a groove 31 is formed in a series in the lateral direction across the top surface 24a on the contact surface 24c of the lid-side hinge block 24. The through hole 26 is communicated with the groove 31 by closing the contact surface 23c.
[0036]
Further, in the embodiment shown in FIGS. 7 and 8, the communication hole portion 27 forms a groove portion 32 in a row in the lateral direction across the top surface 23a on the contact surface 23c of the main body side hinge block 23. 32 is closed by the contact surface 24 c of the lid-side hinge block 24, and the through-hole portion 26 communicates with the groove portion 32.
[0037]
In any embodiment, like the above-described embodiment, the flowing water hole 25 is formed so that the contact surfaces 23c and 24c of the hinge blocks 23 and 24 are in liquid-tight contact with each other so that the through-hole portion 26 is formed. A series of connections are made to the communication holes 27 formed by the grooves 31 and 32, whereby the inside of the outer cylinder 13 of the cap body 4 is communicated with the outside via the left and right top surfaces 23 a and 24 a of the hinge blocks 23 and 24. It has become so.
[0038]
In the present embodiment, the other end of the water flow hole 25 is between the main body side hinge block 23 and the lid side hinge block 24 that are connected to each other so as to be foldable. Since it comprised, it was possible to clean these groove parts 31 and 32 exposed when the cover body 5 was opened, and the clogging of the water flow hole 25 can be prevented more reliably. Moreover, in this embodiment, since the water flow hole 25 is opened on the left and right of the hinge 6, the water flow hole 25 is conspicuous as compared with the above embodiment opened on the inclined surface 24 b of the lid side hinge block 24. The appearance can be further improved.
[0039]
【The invention's effect】
In short, the cap according to the present invention does not need to be provided with a spring piece or the like that forms a gap or the like in the special lid body, has a good appearance, can prevent clogging by the extract, and / or When the lid is closed, the inside of the cap body is not directly communicated with the outside, and water can be prevented from flowing into the cap body.
