More specifically, the cap body and the cap body can be opened and closed via an outer hinge. A hinge cap having a small lid that is attached to and detached from a cylindrical spout provided in the cap body via an inner hinge.
The present invention relates to a hinge cap having an openable / closable small lid that is controlled by an inner projecting piece and a projection piece formed on the upper lid in conjunction with the opening / closing operation of the upper lid and opening and closing of the small lid at the cylindrical spout.

A hinge cap with an upper lid that is attached to the mouth of the container and connected to the cap body via a hinge can be opened and closed with a single touch, and the upper lid falls and becomes dirty or lost. Since there is no fear, it is preferably used for a container for storing things that are frequently used, such as edible oil and seasonings.
As a general shape of such a hinge cap, the following are known.

Japanese Patent Publication No. 3-53182 Japanese Patent Publication No. 7-59428 Design Registration No. 724522 JP 2005-263269 A Japanese Patent Application No. 2005-261556

As shown in FIG. 6, the hinge cap a of Patent Document 1 is connected to a cap body d attached to a mouth c of a container b with an upper lid e that opens and closes the cap body d by a hinge f. A spout g is provided on the plate, and a ring wall h for opening and closing the spout g is provided on the top plate of the upper lid e.

Patent Document 2 relates to the application of the present applicant, and this hinge cap a1 is shown in FIG.
Since the cylindrical spout i extending in the lateral direction is provided in the top plate portion of the cap body d, the container b is pressed to push the contents out of the cylindrical spout i, and then pressed. When the operation is stopped, the contents remaining in the cylindrical spout i return to the container b due to the restoring force of the container b, and the contents do not hang around the cylindrical spout i. Further, since the projection j that closes the cylindrical spout i is provided on the upper lid e, when the upper lid e is attached to the cap body d, the projection j abuts the cylindrical spout i so that it can be closed. It has become.

Patent Document 3 is related to the applicant's application for design registration. As shown in FIG. 8, this hinge cap a2 is provided with a small lid k of another piece at the cylindrical spout i described in Patent Document 2. It is designed to fit.

Patent Document 4 relates to the application of the present applicant, and this hinge cap a3 is shown in FIG.
As shown, the small lid k attached to the cylindrical spout i can be opened and closed with the hinge as a fulcrum, and the closure of the small lid k is linked to the closing operation of the upper lid e. Closing is performed with the closing operation of the upper lid e without using fingers.

Furthermore, Patent Document 5 is also related to the applicant's application, and as shown in FIG. 10, the hinge cap a4 can be opened and closed with a small lid k attached to the cylindrical spout i as a fulcrum, Moreover, since the opening / closing plug of the small lid k is performed by the small lid opening / closing projection piece m provided in the upper lid e in conjunction with the opening / closing operation of the upper lid e, the opening / closing plug of the small lid k does not use any fingers. , Upper lid e
This is done with the opening / closing lid operation.

However, the hinge cap a described in the above-mentioned Patent Document 1 is suitable for the case where the contents of the container b have a relatively low viscosity, but the viscosity is high and the container b is pressed to bring out the contents from the spout g. In such a case, the liquid content after the contents of the container b are pushed out from the spout g is poor, drooping around the spout g, and the periphery of the spout g may be contaminated. Even if the top cover e is put on, the contents are interposed between the spout g and the ring wall h, so that the plug cannot be completely closed, or the spout g and the ring wall h adhere to the contents. There is a difficulty that prevents smooth opening.

Moreover, since the hinge cap a1 described in Patent Document 2 only closes the cylindrical spout i by bringing the projection j into contact therewith, there is a possibility that the plugging performance of the cylindrical spout i gradually becomes insufficient. Since the hinge cap a2 described in Patent Document 3 is adapted to fit a small lid k as a separate piece into the cylindrical spout i, there is a risk that the small lid k may be dropped and contaminated or lost during use. There is inconvenience.

  Furthermore, the hinge cap a3 described in Patent Document 4 has the convenience of closing the cylindrical spout i with the small lid k in conjunction with the closing operation of the upper lid e. There is an inconvenience that you have to do it with your fingers. On the other hand, the hinge cap a4 described in Patent Document 5 according to the present applicant can open and close the small lid k by the small lid opening / closing protruding piece m provided on the upper lid e without using fingers. At this time, the small lid opening / closing protruding piece m passes over the cylindrical spout i, and the contents may adhere to the small lid opening / closing protruding piece m and stain the periphery.

  Therefore, the object of the present invention is to perform all of the opening / closing operation of the small lid in conjunction with the opening / closing operation of the upper lid as in Patent Document 4, and without touching the small lid with a finger at all, An object of the present invention is to provide a hinge cap having an openable / closable small lid that can reliably open and close the spout with respect to the spout.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
That is, according to the present invention, a cap body having an upper wall and a side wall to be attached to the mouth of the container, a top wall and a skirt wall, and the skirt wall is connected to the cap body via an outer hinge. A hinge cap comprising an upper lid, and a cylindrical spout extending in an obliquely upward lateral direction toward the opposite side to the outer hinge is formed on the upper surface wall of the cap body, and a cylinder spout is formed at the top end of the spout A small lid consisting of a base having an inner ring that fits into the spout is connected via an inner hinge. The small lid projects in both directions perpendicular to the straight line passing through the inner hinge and the center of the base. A flap piece is formed, extending from a skirt wall on the opposite side of the outer hinge of the upper lid, and formed with a pair of inner protruding pieces that interfere with the flap piece when the upper lid is opened and closed to open and close the small lid , Within the pair At the position corresponding to between the protruding pieces, there is formed a protruding piece that protrudes from the inner surface of the upper lid and abuts the upper surface of the small lid when the upper lid is closed to fit the small lid into the cylindrical outlet. The opening of the small lid of the spout is performed by an inner protruding piece formed inside the upper lid when the upper lid is opened, and the closing of the small lid is performed between the inner protruding piece and the protruding piece when the upper lid is closed. There is provided a hinge cap having a small lid that can be opened and closed, which is characterized in that it is performed in cooperation.

According to the present invention, the protruding piece protrudes from the top surface wall and / or the skirt wall inner surface of the upper lid opposite to the outer hinge, and the tip end surface of the protruding piece has a contact surface with the small lid as a vertex. There is provided a hinge cap having a small lid that can be freely opened and closed formed in a gentle chevron.

According to the present invention, there is also provided a hinge cap having a small lid having a stopper that holds the small lid in a range of 90 to 180 ° from the closing position at the top end of the cylindrical spout.

In the hinge cap of the present invention, when the upper lid is opened from the cap body, the protruding piece also moves in conjunction with the upper lid, so that it is separated from the state in contact with the upper surface of the small lid. The inner projecting piece hits both flap pieces of the small lid, and the small lid that is closing the cylindrical spout is moved in the opening direction to open the lid. On the contrary, when the upper lid is closed, the pair of inner protruding pieces hits the flap pieces of the small lid that is opening the cylindrical spout, and the small lid is moved in the closing direction to fit into the cylindrical spout, Further, when the upper lid is kept closed, the projecting piece comes into contact with the upper surface of the small lid and closes the small lid at the cylindrical spout. Therefore, all the opening and closing operations of the small lid have the advantage that it does not require the use of fingers at all, the contents adhere to the user's fingers and stain the fingers, and conversely, the fingers are stained by the fingers. Therefore, it is ideal as a cap for containers that require cleanliness of both. In addition, even for dirt and adhesion due to the contents, by controlling the pair of inner protruding pieces of the upper lid and the protruding pieces of the upper lid with respect to both flap pieces of the small lid, the dirt is prevented and small against the cylindrical spout. The lid can be opened and closed reliably.

In addition, the hinge cap of the present invention is such that when the upper lid closes with respect to the cap body using the outer hinge as a rotation fulcrum, the abutment surface which is the apex of the gentle chevron tip surface of the projection piece abuts against the upper surface of the small lid. And assisting and controlling the insertion of the small lid into the cylindrical spout. Therefore, in addition to the above effects,
The small lid can be smoothly closed with respect to the cylindrical spout, and accordingly, the upper lid with respect to the cap body can be smoothly closed.

The hinge cap of the present invention holds the small lid within a range of 90 to 180 ° from the closing position by the stopper when the small lid is opened. Therefore, in addition to the above effects, the small lid does not return to the closing direction, so that the contents of the container can be poured out smoothly, and the contents do not adhere to the small lid.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, and is a cross-sectional view of a state in which a hinge cap at the time of closing is attached to the mouth of the container, FIG. 2 is a cross-sectional view of the hinge cap of FIG. It is a top view of the state which opened the upper cover of the hinge cap.
In these drawings, a hinge cap (hereinafter simply referred to as a hinge cap) 1 having a small lid that can be opened and closed includes a cap body 6 having an upper surface wall 4 and a side wall 5 to be attached to the mouth 3 of the container 2, and a top wall 7. And an upper lid 10 having a skirt wall 8 connected to the cap body 6 via an outer hinge 9, and the upper wall 4 of the cap body 6 is opposite to the outer hinge 9. A cylindrical spout 11 extending obliquely upward and laterally toward the side is formed.

    A small lid 12 made of a base having an inner ring 12 a fitted into the cylindrical spout 11 is connected to the top end of the cylindrical spout 11 via an inner hinge 13. Flap pieces 14, 14 projecting in both directions perpendicular to the straight line L passing through the inner hinge 13 and the center of the base are formed, extending from the skirt wall 8 on the opposite side of the upper lid 10 from the outer hinge 9, A pair of inner projecting pieces 15 and 15 that open and close the small lid 12 by interfering with 14, 14 are formed, and at positions corresponding to the inner projecting pieces 15 project from the inner surface of the upper lid 10 when the lid is closed. A projection piece 16 is formed in contact with the upper surface of the small lid 12 to insert the small lid 12 into the cylindrical spout 11. An opening / closing plug of the small lid 12 in the cylindrical spout 11 is provided on the inner side of the upper lid 10. A pair of inner protrusions formed on It is obtained so as to be controlled with the piece 15 by the projection piece 16.

The container 2 may be anything as long as the hinge cap 1 can be attached to the mouth 3 thereof.
A squeeze type is preferably used. As shown in FIG. 1, the hinge cap 1 is attached to the mouth 3 of the container 2 with the side wall 5 of the cap body 6 and the annular inner wall 5 a formed inside the side wall 5 from above. In general, a form that is inserted in a sandwiched manner is used. Besides that, although not shown in the figure, a male thread is formed on the outer peripheral surface of the container mouth 3, and the inner peripheral surface of the side wall 5 of the cap body 6 is formed. A female thread corresponding to the male thread described above may be formed and screwed together.

The cap body 6 is formed with an outwardly convex raised portion 4a on the upper surface wall 4, and the cylindrical spout 11 is formed on the side of the raised portion 4a. And the rising part 4a
The surrounding upper surface wall 4 is recessed, so that even if the contents hang down from the cylindrical spout 11, it does not immediately flow out of the outer peripheral wall 17, so that the user's fingers and the surroundings of the container 2 are not soiled.

As described above, the small lid 12 of the present invention is connected to the cylindrical spout 11 of the cap body 6 through the inner hinge 13 so as to be freely opened and closed, so that it can be dropped and contaminated or lost. Because you can avoid the situation in advance, it can be used not only at home, but also for business use that is frequently used.
Its handling is excellent. The small lid 12 has an inner ring 12a.
Is provided, and a good closed state can be maintained by sliding contact between the outer periphery thereof and the inner periphery of the cylindrical spout 11. Further, the flap pieces 14, 14 provided on the small lid 12 are connected to the upper lid 10.
The small lid 12 is opened and closed by being interfered with a pair of flexible inner projecting pieces 15 and 15 provided on the lid. In addition, stoppers 18 and 18 for holding the small lid 12 in a range of 90 to 180 ° from the closing position are provided at the upper end of the cylindrical spout 11. That is, the stoppers 18 and 18 are arranged at positions where the flap pieces 14 and 14 of the small lid 12 are engaged with each other when the upper lid 10 is opened.

  Further, a projection piece 16 is formed on the inner surface of the upper lid 10 between the pair of inner protruding pieces 15, 15 to assist the insertion of the small lid 12 into the cylindrical spout 11. The projection piece 16 is connected to the outer hinge 9. It protrudes from the top wall 7 and / or the skirt wall 8 inner surface of the upper lid 10 on the opposite side, and the tip end surface 16a of the protruding piece 16 is formed in a gentle mountain shape with the contact surface with the small lid 12 as the apex.

Accordingly, when the upper lid 10 is closed with respect to the cap body 6 using the outer hinge 9 as a rotation fulcrum, the abutment surface that is the apex of the gentle chevron tip surface 16 a of the projection piece 16 is the upper surface of the small lid 12. The movement which the small lid 12 fits into the cylindrical spout 11 can be ensured by contact | abutting with respect to 12b. For this reason, the capping of the small lid 12 with respect to the cylindrical spout 11 becomes smooth, and accordingly the closing operation of the top lid 10 with respect to the cap body 6 is also smoothed.

The flap pieces 14 and 14 of the small lid 12 and a pair of inner projecting pieces 15 corresponding thereto,
15, the upper surface 12 b of the small lid 12, and the protruding piece 16 are disposed at positions where they are engaged with each other when the upper lid 10 is opened. As the upper lid 10 is opened, the small lid 12 is also opened. When the small lid 12 is completely opened, the contact state between the upper surface 12b of the small lid 12 and the protruding piece 16 is released, and The engagement state between the flap piece 14 and the pair of inner projecting pieces 15 is also released.

  That is, when the upper lid 10 is opened from the cap body 6, the protruding piece 16 is first released from the upper surface 12b of the small lid 12, the contact state is released, and then the pair of inner projecting pieces 15 and 15 are formed into a cylindrical note. The flaps 14 and 14 of the small lid 12 closing the outlet 11 are hit and the small lid 12 starts to be opened. Then, the inner protruding piece 15 slides over the flap piece 14 and further climbs over the flap piece 14 to completely Will be opened. Accordingly, the small lid 12 can be opened by the action of the protruding piece 16 and the inner protruding piece 15, and in addition, the protruding piece 16 and the inner protruding piece 15, the upper surface 12b of the small lid 12, and the flap piece 14 are mutually compatible. As a result, the opening of the cylindrical spout 11 by the small lid 12 can be made smoother. When the small lid 12 is opened, the flap pieces 14 and 14 get over the stoppers 18 and 18 in the opening direction, so that the small lid 12 is held within a range of 90 to 180 ° from the closing position.

On the other hand, the small lid 12 is also closed in accordance with the closing operation of the upper lid 10, and when the small lid 12 is completely closed, the contact state between the upper surface 12b of the small lid 12 and the protruding piece 16 is maintained, and The engagement state between the flap pieces 14 and 14 and the pair of inner projecting pieces 15 and 15 is released. That is, when the upper lid 10 is closed toward the cap body 6, first, the pair of inner protruding pieces 15 hit the flap piece 14 of the small lid 12 that opens the cylindrical spout 11, and the small lid 12 starts to close. The stopper 18 also gets over in the closing direction, and then the inner projecting piece 15 slips over the flap piece 14 to get over and close, and at the same time, the protruding piece 16 is placed on the upper surface 12b of the small lid 12. Abutting and assisting and controlling the insertion of the small lid 12 into the cylindrical spout 11 will completely close the plug. Therefore, as in the case of the above-described opening, the small lid 12 can be closed by the action of the protruding piece 16 and the inner protruding piece 15, and in addition, the protruding piece 16, the inner protruding piece 15 and the small lid 12 can be closed. Together with the upper surface 12b and the flap piece 14, it is possible to more smoothly close the cylindrical spout 11 with the small lid 12.

  The inner projecting piece 15 and the flap piece 14 can be seen from (c), (d), (e) of FIG. 4 and (i) and (j) of FIG. 5, particularly (j) of FIG. It is necessary to bend in accordance with the opening / closing operation of the small lid 12, and it is preferable that the small lid 12 has appropriate elasticity. Further, the inner projecting piece 15 and the flap piece 14 need only have a width and length that can at least lead the opening / closing operation of the small lid 12.

As described above, the upper lid 10 is connected to the cap body 6 via the outer hinge 9, and the upper lid 10 includes the top wall 7 and the skirt wall 8, and the inner periphery of the open end of the skirt wall 8 is convex. Article 8
a is formed and fits to the outer peripheral wall 17 of the cap body 3 when the upper lid 10 is closed, prevents the upper lid 10 from being unintentionally opened to prevent external contamination, and even if the contents droop from the cylindrical spout 11 In order not to flow out to the outside, the user's fingers and around the container 2 are not soiled.

The outer hinge 9 connects the cap body 6 and the upper lid 10 so as to be openable and closable.
When the container 2 is tilted to pour the contents after the top lid 10 is opened, the top lid 10 turns in the closing direction so as to close the cylindrical spout 11 so as not to prevent the contents from being poured out. A known snap hinge having a spring property is employed.
Moreover, it is preferable that the material of the hinge cap 1 of this invention has moderate rigidity and elasticity, and usually polyethylene, polypropylene, etc. are preferably used.

Further, in the plug opening process, in order for the opening of the upper lid 10 and the opening of the small lid 12 to be interlocked, the pair of inner projecting pieces 15 in the upper lid 10 are located below the flap piece 14 of the small lid 12. There,
When the upper lid 10 is moved in an arc as the lid is opened, the positional relationship must be such that the flap piece 14 of the small lid 12 abuts.
Further, in the plugging step, in order to interlock the closing of the upper lid 10 and the closing of the small lid 12, the pair of inner protruding pieces 15 in the upper lid 10 abut against the flap pieces 14 of the small lid 12, In addition, when the upper lid 10 is moved in an arc as the lid is closed, the small lid 12 must be positioned so as to be able to rotate and move toward the cylindrical spout 11 side with the inner hinge 13 as a fulcrum. In addition, when the upper lid 10 is moved in an arcuate shape, the projecting piece 16 must be in an engagement position relationship so as to contact the upper surface 12 b of the small lid 12.

In order to smoothly perform the opening / closing operation, the inner hinge 13 is connected to the cylindrical spout 11 and the small lid 12 and integrally formed. When the small lid 12 is opened, the stopper 18 is used to close the plug. The small lid 12 is preferably held in the range of 90 to 180 °. By doing in this way, the small lid 12 does not return to the closing direction, and the contents of the container 2 can be smoothly poured out from the cylindrical spout 11, the periphery of the cylindrical spout 11 and the small lid 12, and the top lid 10. Since the periphery of the top wall 7 is not soiled, the above-described opening / closing operation is smooth. In place of the stopper 18, for example, a hinge called a snap type or a flap type described in Japanese Patent Publication No. 63-17717 or Japanese Patent Publication No. 3-53182 may be used.
