BACKGROUND OF THE INVENTION
The present invention relates to a cap that has a good appearance, can prevent clogging due to an extract, and does not directly communicate with the outside of the cap body when the lid is closed.
[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.
[0003]
The cap used in such a container is roughly overlapped on the top of the container body, with a cylindrical cap body that surrounds the periphery of the extraction port, and on the cap body, forming a gap therebetween. The lid body closes the extraction opening of the container body in a freely openable / closable manner, the hinge pivotally connects the lid body to the cap body, and a pair of slits penetrating the lid body toward the gap. And the other end is connected to the cap body and elastically deformed to rotate the lid around the hinge. The container body is turned upside down and the cap is placed on the mounting surface. Thus, the container body can be supported in an inverted state.
[0004]
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.
[0005]
For the purpose of eliminating such problems, caps having a structure that allows water that has flowed into the cap main body from between the container main body and the like to flow out from the slit of the lid body are disclosed in Patent Document 1 and Patent Document 2, for example. It is disclosed.
[0006]
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.
[0007]
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.

[Problems to be solved by the invention]
By the way, in Patent Document 1 described above, 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. The area around the hole is likely to become dirty due to the entry and exit of water, and is not preferable in appearance, and there is a possibility that the extract may clog the small hole when wiping the extract from the extraction hole. was there.
[0010]
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.
[0011]
The present invention was devised in view of the above-described conventional problems, has a good appearance, can prevent clogging due to the extract, and the cap body is outside when the lid is closed. An object is to provide a cap that is not directly communicated.
[0012]
[Means for Solving the Problems]
The cap according to the present invention is formed in a cylindrical cap body having a top plate that surrounds the periphery of the extraction port at the top of the container body, and is formed on the top plate of the cap body and communicates with the extraction port. A lid that overlaps the extraction hole and the cap main body while forming a gap therebetween, and closes the extraction hole of the cap main body so as to be openable and closable. One end is formed in the lid and the other end is coupled to the cap body by a hinge that is movably coupled and a pair of slits that penetrate the lid toward the gap. And an elastic piece for rotating the lid body, and the water flowing into the cap body from between the container body and the container body is allowed to flow out from the slit while supporting the container body in an inverted state. Like In-up, the side wall of the cap body, to form a through hole by penetrating it, to the lid, in the through hole around the sidewall surface in the lid in the closed state of the extraction holes Forming a cover that seals the through-hole from the outside while forming a liquid-tight flow channel that is in liquid-tight contact with the cap body and the lid to communicate the through-hole and the gap. It is characterized by.
[0013]
In the present invention, the through hole is formed on the side wall of the cap body, while the cover formed on the lid body is liquid-tight on the side wall surface around the through hole with the extraction hole portion closed by the lid body. The through hole is sealed from the outside while forming a liquid-tight flow channel that connects the through hole and the gap between the cap main body and the lid, and thus the through hole is capped. because it is formed in the side wall of the body, without much conspicuous dirt that may be adhering to the through-holes or around the time you open the lid, together it is possible to obtain a good appearance, the spout The possibility of the extract reaching the through hole by the operation of wiping the extract from the communicating extraction hole can be reduced, and the through hole can be prevented from being clogged with the extract.

[0016]
The container main body 2 includes a cylindrical body portion 9 for containing an extract, and a shoulder portion 10 formed on the body portion 9 so as to be gradually reduced in diameter from the outer diameter of the body portion 9 and formed into a cone shape. And a neck portion 11 formed on the shoulder portion 10 and having an extraction port 3 for taking out the extract therein.
[0017]
The cap body 4 is suspended from the lower surface of the top plate 12 so as to surround the periphery of the neck portion 11, and the locking portion 13 formed between the neck portion 11 and the cap body 4 is interposed therebetween. The inner cylinder part 14 to be locked and the outer side of the top plate 12, which surrounds the outer peripheral edge and hangs down toward the shoulder part 10, forms a side wall of the cap body 4, and forms the cap body 4 into a tubular shape. The outer cylinder portion 15 is configured. At the center portion of the top plate 12, an insertion portion 16 that protrudes from the lower surface and press-contacts to the inner periphery of the extraction port 3 and a raised portion 17 that protrudes from the upper surface are formed. An extraction hole 18 is formed over the insertion part 16.
[0018]
The cap body 4 is formed by engaging the inner cylinder portion 14 with the neck portion 11 while inserting the insertion portion 16 into the extraction port 3 so that the extraction hole portion 18 communicates with the extraction port 3. A cylindrical portion 15 or the like surrounds the periphery of the extraction port 3 so as to cover the upper portion of the container body 2.
[0019]
The lid 5 is formed in a dish-like shape as a whole from a top plate 19 whose outer contour is formed so as to match the outer contour of the top plate 12 and an annular peripheral wall 20 formed by hanging from the outer peripheral edge of the top plate 19. Is done. At the center of the top plate 19, a plug body 21 is formed so as to protrude from the extraction hole 18 so as to be freely inserted and removed, thereby closing the extraction port 3 so as to be opened and closed.
[0020]
The plug body 21 is formed in a hollow shaft shape so as to be elastically deformable, and an annular protrusion 22 is formed around the plug body 21. When the plug body 21 is inserted into the extraction hole portion 18, the plug body 21 is formed with respect to the tapered surface 23 above the extraction hole portion 18. The annular projection 22 is detachably engaged with the stepped portion 24 in the extraction hole portion 18 while being deformed flexibly, and thereby the extraction hole portion 18 and thus the extraction portion are extracted. The mouth 3 is liquid-tightly closed by the plug body 21, and the annular peripheral wall 20 of the lid body 5 is liquid-tightly superimposed on the top plate 12 of the cap body 4. At this time, a gap S is formed between the top plate 12 of the cap body 4 and the top plate 19 of the lid 5 by the annular peripheral wall 20.
[0021]
The hinge mechanism 8 is a so-called snap hinge, and includes a hinge 6 including a main body side hinge block 25 and a lid side hinge block 26, and an elastic piece 7. The body-side hinge block 25 and the lid-side hinge block 26 are each formed to protrude from the outer cylinder portion 15 and the annular peripheral wall 20 at intervals in the circumferential direction thereof, and the protrusion-side tips thereof are connected to each other so as to be foldable. A lid 5 is pivotally connected to the cap body 4.
[0022]
Between the hinge blocks 25 and 26, an elastically deformable belt-like elastic piece 7 that connects the outer cylinder portion 15 of the cap body 4 and the lid 5 is formed. The elastic piece 7 extends from the annular peripheral wall 20 of the lid 5 to the top plate 19 and penetrates the lid 5 toward the gap S formed when the lid 5 is superimposed on the cap body 4. The slits 27 are juxtaposed between the slits 27, and one end 7 a thereof is formed integrally with the lid 5. The other end 7 b of the elastic piece 7 is integrally connected to the outer cylinder portion 15 of the cap body 4.
[0023]
The elastic piece 7 is elastically deformed between the outer cylinder portion 15 and the lid body 5 in a folding process of the hinge blocks 25 and 26 that are foldably connected. The body 5 is given a closing habit and an opening habit, whereby the lid body 5 is rotated around the hinge 6. On the opposite side of the hinge mechanism 8, a finger-hanging projecting piece 28 is formed that protrudes outwardly from the annular peripheral wall 20 of the lid 5 in a hook shape and serves as a clue when the lid 5 is opened.
[0024]
In particular, a through-hole 29 is formed in the outer cylinder portion 15 serving as a side wall of the cap body 4 so as to penetrate therethrough. In the present embodiment, the through hole 29 is formed at a position opposite to the hinge mechanism 8 by notching the outer cylinder portion 15 downward from its upper end 15a into a groove shape with a considerable depth. Therefore, the through-hole 29 penetrates the outer cylinder portion 15 in the lateral direction and communicates with the inside of the outer cylinder portion 15 immediately below the top plate 12, and in addition to this, is defined by the outer peripheral edge of the top plate 12. By doing so, it is communicated also to the lid body 5 side superimposed on the cap body 4.
[0025]
And between the cap main body 4 and the cover body 5, the liquid-tight flow channel which makes the through-hole 29 and the space | gap S inside the cover body 5 connect in the state which closed the extraction port 3 with the cover body 5. Sealing means 31 forming 30 is provided. In the present embodiment, the sealing means 31 is formed on the surface of the outer cylinder portion 15 around the through-hole 29 and the lid 5 and is a plate-like cover 32 that is in liquid-tight contact with the surface of the outer cylinder portion 15. It consists of. The cover 32 is formed so as to hang from the finger-hanging projection piece 28 onto the surface of the outer cylinder portion 15 in correspondence with the position of the through hole 29. A flat surface 33 is formed by recessing the surface of the outer cylinder portion 15 around the through hole 29, and a flat surface 34 superimposed on the flat surface 33 of the surface of the outer cylinder 15 is also formed on the cover 32. The flat surfaces 33 and 34 are formed so that the cover 32 and the surface of the outer cylinder portion 15 are in liquid-tight contact with each other.
[0026]
The cover 32 is brought into liquid-tight contact with the surface of the outer cylindrical portion 15, whereby the through-hole 29 formed by cutting out into a groove shape is sealed from the outside, and between the through-hole 29 and the gap S. A liquid-tight flow channel 30 is formed. In the illustrated example, since the annular wall portion 20 is positioned immediately above the through hole 29, the annular wall portion 20 has a groove portion 35 that communicates the through hole 29 with the gap S in series from the cover 32. Is formed. In the above embodiment, the through-hole 29 is formed by cutting the outer cylinder portion 15 into a groove shape. Instead, the through-hole 29 is formed by simply penetrating the outer cylinder portion 15 in the lateral direction. In this case, a vertical groove from the through hole 29 toward the space S may be formed in the cover 32.
[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 top plate 19 of the lid body 5 on the mounting surface. It is like that.
[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. 4, and the shoulder 10 of the container body 2 and the cap body 4 flows into the inside of the cap body 4 through a gap between the outer cylinder portion 15 and the outer cylinder portion 15. The water that has flowed through the outer cylindrical portion 15 and the inner cylindrical portion 14 of the cap body 4 and the top plate 12 reaches a through hole 29 formed through the outer cylindrical portion 15.
[0029]
Around the through hole 29, the cover 32 and the surface of the outer cylinder portion 15 are in liquid-tight contact with each other at their flat surfaces 33 and 34, and water is formed by the cover 32 and the surface of the outer cylinder portion 15. It flows down from the through hole 29 to the groove portion 35 of the annular peripheral wall 20 through the flowing water channel 30 and flows into the gap S sealed by the top plate 12 of the cap body 4 and the annular peripheral wall 20 of the lid 5. Then, the water that has flowed into the gap S flows out to the outside through the slit 27 formed from the annular peripheral wall 20 of the lid 5 to the top plate 19, so that the water enters the cap body 4. Accumulation can be prevented.
[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 mechanism 8 as usual, and the plug body 21 is extracted from the extraction hole 18 and opened. For example, the extract can be taken out from the extraction port 3 through the extraction hole 18, and after removal, the top surface of the top plate 12 around the extraction hole 18 is wiped, and then the lid 5 is rotated to turn the cap body 4, the extraction hole 18 is closed by the stopper 21, the annular peripheral wall 20 is brought into contact with the top plate 12 to form a space S, and the cover 32 is brought into contact with the surface of the outer cylinder 15. As a result, a liquid-tight flow channel 30 is formed.
[0031]
In the cap 1 according to the present embodiment described above, the liquid that allows the through-hole 29 and the gap S to communicate with each other by the blocking means 31 while the through-hole 29 is formed in the outer cylinder portion 15 of the cap body 4. Since the dense water channel 30 is formed and the through hole 29 is formed in the outer cylinder portion 15 in this way, there is not much dirt that can adhere to the through hole 29 and its surroundings when the lid 5 is opened. It is not conspicuous and can obtain a good appearance, and when wiping the extract from the extraction hole 18 on the top plate 12, the possibility of the extract reaching the through hole 29 can be reduced, It is possible to prevent the through hole 29 from being clogged with the extract.
[0032]
Furthermore, when the extraction port 3 is closed with the lid 5, the liquid-tight flow channel 30 that allows the through hole 29 and the gap S to communicate with each other can be formed by the sealing means 31. In the closed state, it is possible to prevent the inside of the cap body 4 from directly communicating with the outside through the through hole 29, thereby preventing water from flowing into the inside of the cap body 4.
[0033]
FIG. 5 shows another embodiment. In this embodiment, the through hole 29 and the blocking means 31 are formed at an intermediate position between the hinge mechanism 8 and the finger-hanging projection piece 28. . Thus, these through-holes 29 and the like can be formed at appropriate positions in the circumferential direction of the lid 5 and the cap body 4, and even in such an embodiment, the same operations and effects as in the above-described embodiment can be achieved. Of course.
[0034]
【The invention's effect】
In short, the cap according to the present invention has a good appearance, can prevent clogging due to the extract, and when the lid is closed, the inside of the cap body is in direct communication with the outside. It is possible to prevent water from flowing into this.
