Description

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

``Prior Art'' A container is known in which a cap is fitted onto the outer surface of the mouth and neck of the container body, and engaging protrusions formed on the outer surface of the mouth and neck and the inner surface of the circumferential wall of the cap are engaged with each other. It is being

``Problem to be solved by the invention'' The above-mentioned conventional container has a structure in which the engaging protrusion on the outer surface of the mouth and neck and the engaging protrusion on the inner surface of the cap circumferential wall are connected by forcibly pulling up the cap relative to the container body. The engagement is disengaged and the cap is removed, but it is not easy to form the container body and the cap so that the two engagement protrusions properly engage, and slight dimensional errors may cause The problem was that it was difficult to disengage.

The present invention eliminates the above-mentioned drawbacks and makes it possible to easily remove the cap.

"Means for Solving the Problems" An inward flange 6 is attached to the inner periphery of the tapered shoulder 5 formed at the upper end of the body 4, and a mouth and neck part 7 is erected from the inner periphery of the inward flange. A container body 1 having first and second engaging protrusions 9 and 8 provided around the outer surface of the mouth and neck part and the outer circumferential upper end of the body part 4, respectively, and a flange-like part that is loosely fitted on the outer surface of the lower end of the mouth and neck part 7. Board 12
The inner peripheral part is placed on the upper surface of the inward flange 6, and the flange-like plate is provided with a plurality of notches 13, and the first flange-like plate 12 is suspended from the outer peripheral edge of the flange-like plate 12 via a flexible hinge 11. A third engagement member is provided on the inner surface of the lower end of the peripheral wall 10 and engages with the lower surface of the second engagement protrusion 8.
The lower end of the second peripheral wall hanging down from the periphery of the top wall 15 is brought into contact with the operating tube 2 having the engaging protrusion 14 around it, and the upper surface of the inner peripheral part of the flange-like plate 12, and the lower end of the second peripheral wall is brought into contact with the lower end of the inner surface of the second peripheral wall. A circumferentially provided fourth engagement protrusion 18 is formed from a cap 3 engaged with the lower surface of the first engagement protrusion 9.

``Function'' To remove the cap 3, all you have to do is push down the peripheral edge of the operating tube 2 as shown by the arrow. Then, operation tube 2
The peripheral wall 10 slides on the outer surface of the reduced diameter body of the container body 1 and descends downward, and accordingly the flange-like plate 1
2 deforms into a tapered shape using the upper end corner A of the tapered shoulder 5 as a fulcrum, so that the inner circumferential wall 17 of the cap 3
, thereby causing the first and fourth engaging protrusions 9,
18 is disengaged and the cap 3 is removed. still,
To attach the cap 3, simply push it into the mouth and neck 7.

``Embodiment'' Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings. In each figure, 1 is a container body, 2 is an operating tube fitted and attached to the lower end of the outer surface of the mouth and neck of the container body 1, and 3 is a cap that is fitted into the mouth and neck of the container body and is removed by pushing down the operation tube 2, and each part is molded and manufactured from a synthetic resin material.

The container body 1 has an inward flange 6 attached to the inner periphery of a tapered shoulder 5 formed at the upper end of the body 4, and a mouth and neck part 7 erected from the inner periphery of the inward flange. A first engagement protrusion 9 is provided at the middle part of the outer surface of the mouth and neck part, and a second engagement protrusion 8 is provided on the outer surface of the upper end of the small outer diameter part, with the upper part of the body 4 being a small outer diameter part.
They are located around each other.

The operation tube 2 has the inner peripheral part of the flange-like plate 12 that is loosely fitted on the outer surface of the lower end of the aforementioned mouth neck 7 placed on the upper surface of the aforementioned inward flange 6, and is flexible from the outer peripheral edge of the flange-like plate. The first peripheral wall 1 via the hinge 11
0 is hung down, and the above-mentioned second
A third engagement protrusion 14 that engages with the lower surface of the engagement protrusion 8 is provided around the periphery. Further, the flange-like plate 12 includes:
A plurality of cuts 13 are formed at equal intervals.

The cap 3 has a second circumferential wall hanging down from the periphery of the top wall 15, and the second circumferential wall is made up of double inner and outer circumferential walls 17, 16, and a fourth wall is provided around the lower end of the inner circumferential wall 17. The mating protrusion 18 is engaged with the lower surface of the first engaging protrusion 9 described above, and the lower end of the inner peripheral wall 17 is brought into contact with the upper surface of the inner peripheral part of the flange-like plate 12 described above.

In addition, 19 is packing.

"Effect of the invention" The present invention has the above-mentioned structure, and an inward flange 6 is attached to the inner circumference of the tapered shoulder 5 formed at the upper end of the container body body 4, and the inward flange is The inner periphery of the flange-like plate 12 of the operation cylinder 2 is placed on the upper surface, and the lower end surface of the second peripheral wall of the cap 3 is brought into contact with the inner periphery of the upper surface of the flange-like plate, so that the container body 1 can be operated. When the cylinder 2 is pushed down, the flange-like plate 12 is moved around the corner A at the upper end of the tapered shoulder 5 as a fulcrum.
deforms into a tapered shape, pushes up the second peripheral wall of the cap, and disengages the first and fourth engaging protrusions 9, 18. Therefore, using the principle of leverage, the first,
The engagement between the fourth engagement protrusions 9 and 18 can be released, and the cap 3 can therefore be easily removed from the mouth and neck. In addition, since the operation tube 2 is fitted to the lower end of the outer surface of the mouth and neck 7, it is possible to press down the operation tube by placing a plurality of fingers on the operation tube, so that the fingertips do not easily slip during the operation, and Since the pressing operation is performed with a plurality of fingers in this way, the force required to disengage the first and fourth engagement protrusions 9 and 18 can be easily obtained, and therefore, even if Even if the engagement between the first and fourth engagement protrusions 9 and 18 is too tight due to dimensional errors, the engagement can be easily achieved by utilizing the lever principle as described above. Can be removed. Furthermore, since the operation tube 2 is fitted to the lower end of the outer surface of the mouth and neck part 7 and the lower end of the second peripheral wall of the cap is brought into contact with the inner circumferential portion of the upper surface of the flange-like plate 12 of the operation tube, the operation tube 2 is not easily attached to the container body. By pressing down, the entire cap can be pushed up evenly, and the first and fourth engaging protrusions 9 and 18 can therefore be reliably disengaged.
