Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns containers with caps.

"Problems to be solved by conventional techniques and inventions" For example, the container described in Japanese Utility Model Application Publication No. 131537/1987 includes a container body in which a first engagement protrusion is provided around the outer surface of the mouth and neck, and the container body The cap is fitted on the outer surface of the mouth and neck, and the cap has a plurality of elastic plates hanging from the center of the top wall that closes the upper end surface of the mouth and neck, and a plurality of elastic plates attached to the lower end of the inner surface of the elastic plates. The second engagement protrusion was engaged with the lower surface of the first engagement protrusion, and the side wall was suspended from both the front and rear peripheral edges of the top wall, and the side wall was fitted into the opening between the left and right ends of these side walls. Both corner parts of the lever, which is L-shaped in longitudinal section, are pivoted to the left and right lower ends of the above-mentioned side walls, and when the upper end of the lever is rotated diagonally downward and inward about the pivot parts, the inner end of the lever touches the shoulder of the container body. Pull up the cap by pressing the top surface of the first
The second engaging protrusions are formed to be disengaged from each other.

However, in the above conventional example, the levers provided on both sides of the cap are formed to be pushed inward, so the elastic plate hanging from the center of the top wall of the cap gets in the way, and the upper end of the lever comes into contact with the outer surface of the elastic plate. Then, the lever cannot be rotated any further. Therefore, the amount of rotation of the lever and therefore the amount of push-up of the cap is not sufficient, and if a manufacturing error occurs and the cap is pushed up more than originally planned, the first and second engagement protrusions will engage. When something unavoidable occurred, they were unable to respond. In addition, in order to eliminate this inconvenience and increase the amount by which the cap can be pushed up, it is necessary to increase the gap between the inner surface of the lever and the outer surface of the elastic plate.
A new inconvenience arises in that the cap becomes larger.

By providing a lever on the upper surface of the top wall of the cap, the present invention avoids increasing the size of the cap and allows the lever to be rotated sufficiently without being hindered by anything. To provide a container in which the cap and the mouth and neck can be reliably disengaged from each other even if manufacturing errors occur.

"Means for Solving the Problems" A container body 8 having a first engaging protrusion 10 around the outer surface of the middle part of the mouth and neck part 9 that stands up from the upper end of the body is fitted onto the outer surface of the mouth and neck part 9. The cap includes a first peripheral wall that hangs down from the periphery of the first top wall that seals the upper end surface of the mouth and neck part 9, and the cap fits into the outer surface of the mouth and neck part above the first engagement projection 10. A second top wall 4 is attached to the combined inner cap body 2 and the outer surface of the first peripheral wall.
A second peripheral wall 5 hanging from the periphery is slidably fitted, and a fourth engaging protrusion 7 provided around the lower inner surface of the second peripheral wall can be freely engaged with and detached from the lower surface of the first engaging protrusion 10. an outer cap body 1 having windows 6, 6 in the left and right sides of the second top wall 4 and in the upper left and right sides of a second peripheral wall 5 continuous with the left and right sides of the second top wall;
and the operating lever 3, which is fitted into the windows 6, 6.
3 are respectively placed on the upper surface of the first top wall, and the inner ends of these two operating levers are placed between the lower surface of the second top wall portion between the windows 6 and the center of the first top wall. connected by a flexible plate part 11 between the upper surfaces of the parts,
In addition, the inner end portions of both operating levers 3, 3 are pivotally connected to the outer cap body, and when the outer end portions of both operating levers 3, 3 are rotated upward about the pivoted portion, the inner ends of the operating levers are By pressing the upper surface of the first top wall, the outer cap body 1 is pulled up and the first and fourth engaging protrusions 10, 7 are engaged with and detachable from the operating member.

"Function" In the above, normally the lower surface of the pair of operating levers 3, 3 is connected to the inner cap body 2, as shown in the left half of FIG.
The outer cap body 1 rests on the upper surface of the first top wall and lies down, and the outer cap body 1 is fitted onto the outer surface of the container mouth neck 9 with the fourth engagement protrusion 7 engaging with the lower surface of the first engagement protrusion 10. At this time, the first top wall of the inner cap body 2 closes the upper end surface of the container neck.

Next, to remove the cap, as shown in the right half of FIG. 1, the outer ends of the pair of operating levers 3, 3 are simultaneously raised upward and operated. Then pin 1
The operating levers 3, 3, which are about to rotate about 2, 12 as fulcrums, touch the inner cap body 2 at their inner end lower surfaces A, A.
However, since the inner cap body 2 cannot be moved downward, the outer cap body 1 rises upward, and the fourth engagement protrusion 7 is pushed away from the bottom surface of the first engagement protrusion 10. It comes off and the cap separates from the mouth and neck region 9.

In addition, if the container falls over, the impact may cause the first
Even if one operating lever 3 is in the upright state as shown in the figure, in this case, the fourth engagement protrusion 7 and the first
Only the relevant part of the engagement of the engagement protrusion 10 is disengaged, and the cap does not come off and is safe. Moreover, in this case, the inner cap body 2 is located at the inner end of the lower surface of the operating lever 3 that is upright. Since it is pushed downward and seals the container mouth even more firmly, there is no concern that the contents will leak.

Furthermore, when inserting the cap, it is sufficient to simply push it into the container neck 9.

``Example'' The container of the present invention consists of a container body 8 and a cap fitted on the outer surface of the mouth and neck of the container body, and the container body has a middle part of the outer surface of the mouth and neck 9 which stands up from the upper end of the body, and a cap that First and second engagement protrusions 10 and 13 are provided around the upper part of the mouth and neck part 9, and a peripheral wall of the spouting cap 14 is fitted to the outer surface of the upper part of the mouth and neck part 9, and a third engagement member is attached to the inner surface of the lower end of the peripheral wall. The mating protrusion is engaged with the lower surface of the second engaging protrusion 13.

The cap is formed of three members: an inner cap body 2, an outer cap body 1, and an operating member. The peripheral wall hangs down, and the first peripheral wall is fitted to the outer surface of the mouth and neck portion above the first engaging protrusion 10.

The outer cap body 1 has a circumferential wall portion other than the upper part of the second circumferential wall 5 hanging down from the circumferential edge of the second top wall 4 slidably fitted to the outer surface of the first circumferential wall, and a lower part of the second circumferential wall. A fourth engaging protrusion 7 provided around the inner surface is removably engaged with the lower surface of the first engaging protrusion 10 described above. In addition, windows 6, 6 are opened in the left and right sides of the second top wall 4 and in the upper left and right sides of the second peripheral wall 5 which is continuous with the left and right sides of the second top wall. Side walls 15, 15 are provided hanging from the upper surface of the top wall. In addition, when the cap is removed from the mouth and neck part 9, the fourth engaging protrusion 7 is formed to prevent the inner cap 2 from falling out of the outer cap 1.

The operating member is fitted into the windows 6, 6 described above, and the lower surfaces of the operating levers 3, 3 are placed on the upper surface of the first top wall, respectively, and the inner ends of the operating levers are connected to each other. , the lower surface of the second top wall portion between the windows 6 and the central portion of the upper surface of the first top wall are connected by an arch-shaped flexible plate portion 11. In addition, the pins 12, 12 attached to the inner end portions on both sides of the operating levers 3, 3,
When the outer ends of the operating levers 3, 3 are fitted rotatably into the shaft holes bored in the side walls 15, 15 mentioned above, and the outer ends of the operating levers 3, 3 are pushed upward around the pins 12, 12, the inner ends of the operating levers is the point of action and the first part of the inner cap body 2
By pressing the top wall, the non-described cap 1 rises, and the first and fourth engaging protrusions 10, 7 are formed to be able to be disengaged from each other. In addition, 16, 16 are protrusions for finger rests.

Each of the above members is made of synthetic resin material.

``Effect of the invention'' The present invention has the above-mentioned structure, and windows 6 are provided on both left and right sides of the second top wall 4 of the outer cap 1 and on the upper left and right sides of the second circumferential wall 5 that is continuous with the left and right sides of the second top wall 4. 6 are opened, and the lower surfaces of the operating levers 3, 3 are respectively placed on the upper surface of the first top wall by fitting them into both the windows 6, 6, and the operating levers 3, 3 are placed near the inner ends of the operating levers 3, 3. When the outer ends of the operating levers 3, 3 are pivoted on both sides of the windows 6, 6, and the outer ends of the operating levers 3, 3 are pivoted upward about the pivoted parts, the inner end of the operating levers are connected to the first part of the inner cap body. By pressing the top wall, the outer cap 1 is pulled up and the first and fourth engaging protrusions 1 are pulled up.
Since the engagement of the first and fourth engagement protrusions 10 and 7 is made removable, unless both operating levers 3 and 3 are operated at the same time, the engagement of the first and fourth engagement protrusions 10 and 7 will not be disengaged. Even if the container is accidentally knocked over or one of the operating levers 3 becomes stuck due to a child's mischief, the lid will not open and is safe. Since the body 2 is firmly pressed against the top of the container mouth instead of the lower surface of the inner end of the operating lever 3, the sealing is further strengthened, so there is no fear of liquid leakage.

Furthermore, with the above configuration, there is nothing that obstructs the upward rotation of the outer ends of the operating levers 3, 3 about the pivot joints, and therefore, the amount of rotation of the operating levers 3, 3 is large. , the amount by which the outer cap body 1 is pushed up becomes large, and therefore, if a manufacturing error occurs and the cap is not raised more than originally planned, first,
Even if the fourth engagement protrusions 10 and 7 cannot be disengaged, the outer cap body 1 can be reliably raised until the engagement is disengaged, and the lid can be opened. The operation can be performed reliably. Further, since the operating levers 3, 3 are formed on the upper surface of the outer cap body 1, and the outer end of the operating lever is formed to rotate upward, the amount of rotation of the operating lever is large, but Unlike the previous example, there is no problem such as an increase in the size of the cap.
