Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a container with a cap.

``Problems to be solved by conventional techniques and ideas'' For example, the container shown in Japanese Utility Model Application Publication No. 59-159545 has an engaging projection on the outer surface of the mouth and neck that rises from the upper end of the body through the shoulder. It consists of a container body which has a strip around it and sloped surfaces on the front and rear, left and right sides of the upper surface of the shoulder, and a cap that is fitted onto the outer surface of the mouth and neck, and the cap has a ridge between the top wall periphery and the center. A dual inner and outer circumferential wall is suspended from the inner circumferential wall, the inner circumferential wall is fitted to the outer surface of the mouth and neck, and through holes are bored at both the left and right lower portions of the inner circumferential wall. An oval ring having an inner diameter larger than the outer diameter of the inner circumferential wall is loosely fitted into the ring, and engagement plate portions are protruded from the inner surfaces of both left and right sides of the ring through the through holes, and both of the engagement plate portions are connected to the engagement protrusion. By engaging the lower surface of the cap and rotating the cap relative to the container body, the cap is pushed up using the sloped surface of the shoulder and the ring is elastically deformed. The engagement plate portion is formed so as to be disengaged. in this way,
In the conventional example, the ring is elastically deformed by pushing up the ring by using the slope of the shoulder part and letting the engagement plate part of the cap rest on the engagement protrusion of the mouth and neck part. In other words, the force that pushes up the ring must be converted into the force that elastically deforms the ring, resulting in a large loss.In addition, the ring must be elastically deformed as a whole, so the ring cannot be easily deformed elastically. , the lid could not be opened easily.

In this proposal, elastic plates are provided diagonally upward and inwardly protruding from the lower edges of the notches of the top opening formed on the upper left and right sides of the inner circumferential wall of the cap, and the elastic plates are erected from both the left and right upper ends of the elastic plates. The cap can be opened and closed easily by using an elastic gripping piece to forcibly ride over the elastic gripping piece and detachably grip the engagement protrusion vertically installed on the outer surface of the mouth and neck of the container body by rotating the cap relative to the container body. It was set up so that you can.

"Means for Solving the Problem" A container body 1 has engaging protrusions 5, 5 vertically disposed on the outer surface of the upper left and right sides of a mouth and neck part 4 which stands up from the upper end of a body part 2 via a shoulder part 3, and the mouth The cap consists of an outer cap body 10 having a peripheral wall 13 hanging down from the periphery of the top wall 11 that closes the upper end opening of the mouth and neck part 4, and a cap 9 fitted on the outer surface of the neck 4, and An inward flange 1 is attached to the lower end of the fitted outer peripheral wall 17.

The engaging protrusions 5, 5 are held in place by the elastic clamping pieces 22, 22, which stand up from both the upper left and right sides of the elastic plates.
With this rotation, the elastic clamping pieces 22, 22 are forcibly overcome and clamped in a detachable manner.

"Operation" When the cap 9 is rotated to the right or left with respect to the container body 1 from the state shown in FIG.
22 is pushed by the engaging protrusions 5, 5 and elastically bent in the radial direction of the cap 9, and the engaging protrusions 5, 5 forcibly climb over the elastic clamping pieces 22, 22 to form the elastic clamping pieces 22, 22. leave from between. So, cap 9
It can be removed by pulling it up.

In addition, when closing the cap 9,
When the cap 9 is pushed down with the lower part of the inner circumferential wall 19 shallowly fitted to the upper outer surface of the elastic plate 21,
21 is pushed by the engagement protrusions 5, 5 and elastically deforms, and the engagement protrusions 5, 5 are forced to overcome the elastic plates 21, 21 and are held by the elastic clamping pieces 22, 22,
The closed state of the cap 9 is maintained.

``Example'' The container of the present invention consists of a container body 1 and a cap 9 fitted to the outer surface of the mouth and neck of the container body.
The mouth and neck part 4 is erected from the upper end of the body part 2 via the shoulder part 3, and protrusions 5, 5 are attached to the upper outer surface of the left and right sides of the mouth and neck part.
are installed vertically. Further, the lower part of the nozzle tube 6 is fitted into the upper outer surface of the mouth and neck section 4, and the engagement ridge 7 attached to the upper end of the outer surface of the mouth and neck section 4 prevents the nozzle tube from being pulled out.

The cap 9 consists of an outer cap body 10 and an inner cap body 16. The outer cap body 10 seals the outlet of the nozzle tube 6 described above with a stopper 12 attached to the center of the lower surface of the top wall 11. A peripheral wall 13 hangs down from the periphery of the wall 11 to the upper surface of the outer periphery of the shoulder portion 3, and engagement grooves 14, 14 are formed on both left and right lower portions of the inner surface of the peripheral wall. Further, the inner cap body 16 has an inward flange 18 attached to the lower end of the outer circumferential wall 17 fitted on the inner surface of the circumferential wall 13, and an inner circumferential wall 19 that stands up from the inner circumferential edge of the inward flange to the outer surface of the mouth and neck 4. Elastic plates 21, 21 are loosely fitted into the inner circumferential wall 19, and protrude obliquely upwardly and inwardly from the lower edges of the upper surface opening notches 20, 20 formed in the upper portions of both left and right walls of the inner circumferential wall 19. Elastic clamping pieces 2 that stand up from both the left and right sides of the upper end
2 and 22, the engaging protrusions 5 and 5 are connected to the container body 1.
The rotation of the cap 9 against the elastic clamping pieces 22, 2
2 is forcibly climbed over and held in such a way that it can be detached.
In addition, 23 shows an engagement protrusion, and the above-mentioned engagement groove 14,
14.

"Effect of the invention" The present invention has the above structure, and the elastic plate 2
The engaging protrusions 5, 5 are held by the elastic clamping pieces 22, 22 standing up from both the left and right sides of the upper ends of the caps 1, 21, and the elastic clamping pieces 22, 22 are held by the rotation of the cap 9 relative to the container body 1.
Since the cap 9 is forcibly crossed over and clamped so as to be detachable, the elastic clamping pieces 22, 22 are elastically bent in the radial direction of the cap 9 using the force of rotating the cap 9, and the elastic clamping pieces 22, 22 are The engaging protrusions 5, 5 can be removed from the elastic clamping pieces 22, 2, and there is little loss of force unlike the conventional example.
2 is elastically bent as in the conventional example described above.
It is easy to deform the ring as a whole by elastically deforming it, and the engaging protrusions 5, 5 can be removed from between the elastic clamping pieces 22, 22 by simply rotating the cap 9 slightly.
Therefore, the cap 9 can be easily removed, and the elastic plate 21 extends diagonally upwardly inward from the lower edges of the notches 20, 20 formed on the upper left and right walls of the inner circumferential wall 19. , 21 protrude, the cap 9 removed from the mouth and neck is pushed down with the lower part of the inner circumferential wall 19 shallowly fitted to the upper outer surface of the mouth and neck 4, thereby forcing the elastic plates 21, 21. The elastic clamping pieces 2
2 and 22, the cap can be easily closed, and even if the cap is held when carrying the container,
Since the lower ends of the engaging protrusions 5, 5 come into contact with the upper surfaces of the elastic plates 21, 21 and prevent the cap from being pulled out, there is no risk that the container body will fall even if the cap is carried by the user.
