Description

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

"Prior art" For example, as shown in Japanese Utility Model Publication No. 11236/1983,
It consists of a container body and a cap that is removably fitted to the outer surface of the mouth neck of the container body, and an engaging protrusion is provided around the outer surface of the mouth neck of the container body, and a neck is provided in the peripheral wall of the cap. an elliptical elastic ring is fitted to the outer surface of the cap, and an elliptical elastic ring is engaged with the lower surface of the engagement protrusion, and a handle protruding from both left and right ends in the longitudinal direction of the ring is passed through both left and right sides of the cap peripheral wall. When a push button attached to the outer end of the handle is pushed in the opposite direction, the ring portion is elastically deformed and detached from the lower surface of the engagement protrusion, and in this state, the cap can be attached to and detached from the mouth neck of the container body. I have an idea.

``Problem to be solved by the invention'' In the conventional container with a cap described above, the elliptical ring must be elastically deformed by pushing the push buttons protruding from both the left and right sides of the cap circumferential wall inward to the circumferential wall. It required a lot of force to push it in.

In this case, instead of the above-mentioned ring, a pair of front and rear half-ring-shaped parts are engaged with the lower surfaces of both the front and rear halves of the engagement protrusion on the container mouth neck, and window holes are bored in the left and right end walls of the cap peripheral wall. When the convex part of the push button that projects outward from the button is pushed in, the wedge-shaped plate attached to the push button moves the half-ring part apart against the elastic force and disengages from the engagement ridge on the outer surface of the mouth and neck. This makes it possible to easily disengage the cap from the mouth and neck of the container body by applying the force of the wedge.

"Means for Solving the Problem" A container body 1 having a mouth and neck part 4 erected from the upper end of a body part 2 via a shoulder part 3 and an engaging protrusion 5 provided around the outer surface of the mouth and neck part; Left and right end walls 9a of a peripheral wall 9 hanging from the outer periphery of the top wall 8 that closes the upper end opening surface of the neck 4;
Window holes 13, 13 are respectively drilled in 9a, and a pair of front and rear elastic strips 10, 10 are installed between both end wall portions below both of these window holes, and in the middle part of both strips, Half-ring-shaped portions 11, 11 that engage with the front and rear lower surfaces of the engaging protrusion 5, respectively, are shaped, and gaps between the strip plates 10, 10 are formed at both end portions of the half-ring-shaped portions. The cap body 7 has sloped protrusions 10a, 10a that are wide on the end walls 9a, 9a side and narrow on the half-ring-shaped parts 11, 11 side, and on both left and right ends of the above-mentioned band plates 10, 10. A wedge-shaped plate portion 15 for separating the protrusions 10a, 10a from the lower surface is placed on each of the lower surfaces thereof.
15 is suspended between both strip plates, and a convex portion attached to the outer surface is formed with a pair of left and right push buttons 14, 14 projecting outward from the window holes 13, 13.

``Operation'' When the convex portions of the push buttons 14, 14 are pushed inward from the state shown in FIG.
Wedge-shaped plate part 1 hanging between the left and right ends of 0 and 10
5 and 15 are protrusions 1 with slopes attached to both ends of half-ring-shaped parts 11 and 11 formed in the middle part of both strips.
0a and 10a are separated. Since these protrusions separate the half-ring-shaped parts 11, 11, the engagement of the half-ring-shaped parts 11, 11 with the lower surface of the engagement protrusion 5 on the neck of the container main body is disengaged. You can remove the cap. When the push buttons are released after removing the cap, the push buttons 14, 14 also return due to the elastic return of the band plates 10, 10, and when the cap is fitted from this state, the half-ring shaped portions 11, 11
After being pushed and expanded by the tapered surface of the engagement protrusion 5, it elastically returns, and the upper surface of the half-ring shaped portions 11, 11 engages with the lower surface of the engagement protrusion 5 again.

``Example'' 1 is a container main body, 2 is a body thereof, 3 is a shoulder, through which a mouth and neck part 4 is erected, and a tapered engagement protrusion 5 is provided around the outer surface of the mouth and neck part. It is set up. Further, a nozzle 6 is fitted into the upper end of the mouth and neck.

A cap body 7 is fitted into the upper part of the container body. The cap body extends from the peripheral edge of the top wall 8 to the peripheral wall 9.
be installed vertically. As shown in FIG. 2, the cap main body is preferably formed by separately molding a top wall 8 and a peripheral wall 9 and fitting them together. Window holes 13, 13 are bored in both left and right end walls 9a, 9a of the peripheral wall 9, and a pair of front and rear elastic band plates 10, 1 are formed between the end wall portions below these window holes.
0 are constructed almost parallel to each other. Both of these strip plates have half-ring-shaped parts 11, 11 in their intermediate parts with concave parts facing each other, and these half-ring-shaped parts form a ring-shaped part 12.
form. The inner diameter of the ring-shaped portion is approximately the same diameter as the outer diameter of the mouth and neck portion 4, and each half-ring-shaped portion can engage with the lower surface of the engagement protrusion 5. When the cap body is pressed down from above the mouth and neck part 4, the lower ends of these half-ring shaped parts come into contact with the tapered surface of the upper surface of the engagement protrusion 5,
It is expanded against elasticity and can be elastically restored after getting over the engagement protrusion. Further, at each end portion of both half-ring-shaped portions, protrusions 10a, 10a with slopes are provided.
Attached. The slope is provided so that the gap between the two strip plates 10, 10 is wide on the side of the end walls 9a, 9a, and narrow on the side of the half-ring shaped parts 11, 11. A plug portion 16 that fits into the nozzle opening is provided vertically from the center of the top wall 8, and guide plates 17, 17 for horizontally moving a push button, which will be described later, are provided vertically from both the left and right sides.

Reference numeral 14 denotes a push button, the lower surface of which is placed on both left and right end portions of the aforementioned two strip plates 10, 10, respectively, and the wedge-shaped plate portions 15, 15 are suspended from the lower surface between the two strip plates. Also, a convex portion projects outward from both the window holes 13, 13 mentioned above. Push button 1 by pushing the protrusion into the cap body.
4 and 14 move toward the mouth and neck part 4 side, and as a result of this movement, the wedge-shaped plate parts 15 and 15 open the sloped window parts 10a and 10.
the wedge-shaped plate parts 15, 15 so that the half-ring-shaped parts 11, 11 are also separated together with the protrusions a, and the half-ring-shaped parts 11, 11 are disengaged from the lower surface of the engagement protrusion 5. and protrusions 10a, 10
Determine the shape and size of a.

"Effect of the invention" The present invention has the above-mentioned configuration, and the middle part of the pair of front and rear elastic band plates installed between the lower part of the end wall of the peripheral wall of the cap body is engaged with the lower surface of the engagement protrusion 5 of the mouth neck of the container body. Half-ring-shaped parts 11, 11 that meet are provided at each end of the half-ring-shaped parts, such that the gap between the two strips extends from the end wall 9.
Protrusions 10a, 10a with slopes that are wide on the sides a and 9a and narrow on the sides of the half-ring parts 11 and 11 are provided, and wedge-shaped plate parts 15 and 15 for separating the protrusions are provided between the two strip plates. The push buttons 14, 14 are placed on both ends of both strip plates by hanging down, and the push button protrusions are made to protrude outward from the end walls. The force for spreading and separating them is doubled by the wedge mechanism, so that the half-ring-shaped parts 11, 11 can be easily disengaged from the lower surface of the engagement protrusion 5.
