Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a spout-type cap in which a separate canopy that is opened by a push button is pivotally provided on the upper surface of a cap body.

[Problems to be Solved by Conventional Techniques and Inventions] As a dispensing cap type cap with a canopy, a well-known elastic inversion type cap with a three-point support mechanism is typical. This cap has a pouring hole on the top of the cap body, and a bar stopper is hung on the underside of the canopy on the top surface of the cap body. Both of them are integrally joined by thin hinges at three places on the rear side. is there. With this structure, the canopy can be opened and closed with one touch, and the function that stabilizes in any state is convenient, but the molding process is troublesome and the life of the thin hinge part has a problem. For this reason, there are many cases in which the canopy is structured separately from the cap body.

By the way, when the canopy and the cap main body are separated from each other, engaging projections that engage with each other are provided on the outer surface of the cap main body and the inner surface of the canopy, respectively. For example, like the cap described in Japanese Utility Model Laid-Open No. 63-1750, a push button for pushing up the canopy to release the engagement is formed separately from the canopy and the cap body.
It is not preferable because the number of parts increases and the mounting structure becomes complicated.

In the present invention, a part of the canopy is used as a push button for pushing up the canopy, so that the number of parts is reduced and the structure is simplified.

"Means for Solving the Problem" A pouring hole 4 is opened in the central portion of the top wall 3, and a fillet portion 5 is used on both sides of the upper surface near the front portion to form a first outer member. A cap body 1 having mating protrusions 6 and 6 is formed, and a top plate 11 is pivotally mounted on the upper surface of the cap body 1 so as to be openable and closable. A peripheral wall 7 is hung from both parts, and second engaging projections 8, 8 engaging with the lower surfaces of the first engaging projections 6, 6 are projected from both sides of the inner surface of the peripheral wall 7 near the front part. 7 is a plate-like elastically deformable push button 9 that surrounds the front outer surface from both sides of the outer surface.
And a front pressing plate of this push button 9
9a Behind the slanting rearward engaging slant b, a slit 10 into which the rear end of the slant b is inserted is cut out at the lower end of the front side peripheral wall 7 facing the slant b, and the back surface of the top plate 11 extends to the pouring hole 4 It was formed with a canopy 2 on which a rod plug 12 to be inserted was suspended.

[Operation] In the above, the canopy 2 is normally closed on the upper surface of the cap body 1 as shown in FIG. 1, at this time, the rod plug 12 is inserted into the pouring hole 4, and the second engaging projections 8, 8 Is the first engaging projection 6,6
The canopy 2 is held in the closed state by engaging with the lower surface.

Here, in order to open the lid, the front pressing plate 9a of the push button 9 is pushed backward. Then, the both side plate portions 9b, 9b of the push button 9 are bent, the front pressing plate 9a is moved, and the engaging slope B is formed in the slit 10 between the lower end of the front side peripheral wall 7 and the upper surface of the top wall 3 of the cap body 1. Since the front portion of the canopy 2 is pushed upward through the slit 10 by entering, the second engaging protrusions 8 and 8 are disengaged from the first engaging protrusions 6 and 6, the canopy 2 is opened, and the rod stopper 12 is poured. It can be unplugged from the outlet 4.

[Embodiment] The cap of the present invention comprises a cap body 1 attached to the mouth and neck of a container body, and a separate canopy 2 pivotally mounted on the top surface of the cap body 1 so as to be openable and closable. It is characterized in that a push button 9 for opening the lid is formed by a part of the canopy 2.

The cap body 1 includes an elliptical top wall 3 and a peripheral wall 13
The outer peripheral wall 13 is formed with a vertically cylindrical elliptical outer shape, and a true cylindrical mounting peripheral wall 14 is formed on the inner surface of the outer peripheral wall 14. 2 engaging ridges
15 and 16 are provided to project, and the second engaging projection 16 is provided to the mouth / neck portion 18 of the container body 17.
The lower surface of the third engaging projection 19 on the outer surface is engaged with and fitted to the outer surface of the mouth / neck portion 18.

A fill portion 5 is formed in the center of the top surface of the top wall 2 excluding the front portion and the left and right edges, and a pouring hole 4 having an upward spread is formed in the center portion, and the front portion of the fill portion 5 is formed. First engaging projections 6 and 6 directed outward in the lateral direction are projected on both side surfaces of the side, and a groove 20 for a hinge is recessed on the rear end edge. Child
21, 21 projectingly provided, and a recess 22 provided on the upper surface of the outer peripheral wall 13 in the front surface thereof. The cylinder is fitted into the inner plug 23 of the container body neck portion 18 from the top wall 3 inside the mounting peripheral wall 14. The stopper 24 is installed vertically.

The canopy 2 has a shape of a shallow probing plate corresponding to the top wall 3 of the cap body 1 in a top view and is close to an ellipse, and a hinge boss 25 is hung from the rear rear surface of the top plate 11, and this boss 25 is used for the hinge groove. The cap body 1 is fitted into the cap 20 and engages with the protrusions 21 and 21.
It is arranged so that it can be opened on one side.

A bar plug 12 to be inserted into the pouring hole 4 is hung from the center of the back surface of the top plate 11, and a peripheral wall 7 is hung from the front part of the top plate 11 and both left and right parts. Second engaging projections 8 and 8 that engage with the lower surfaces of the first engaging projections 6 and 6 are provided so as to project from inside both sides of the part, and a slit is formed at the lower end edge of the front part of the peripheral wall 7.
Notch 10 is formed. Further, a substantially U-shaped plate-like elastically deformable push button 9 is provided so as to branch from the left and right outer surfaces near the front part of the peripheral wall 7 so as to surround the front outer surface through a gap i of the same shape. Behind the front pressure plate 9a, this pressure plate 9a
An engaging plate 26 is formed which is folded back obliquely rearward and downward from the upper edge to form an obliquely rearward downward engaging slope b. This engagement plate
The hanging end of 26 has a triangular cross section so that it can enter the slit 10. Reference numeral 27 is a reinforcing portion, and 28 is a torsion spring that is attached to the hinge boss 25 portion and constantly biases the canopy 2 in the opening direction.

Therefore, when the pressing plate 9a of the push button 9 is pushed in, the pressing plate 9a moves rearward due to the bending of the side plates 9b, 9b, and the rear end of the engaging plate 26 behind it enters the slit 10 and the engaging sloped surface Since the front portion of the canopy 2 is pushed up via the, the first and second engaging projections 6 and 8 are disengaged, and the rod plug 12 can be unplugged from the pouring hole 4, and then the torsion spring 28 is released. Open 2 to the rear greatly.

The above-mentioned parts are molded and manufactured by a synthetic resin material except for the torsion spring 28.

[Advantage of Device] As described above, in the present invention, the canopy 2 is separate from the cap body 1, and therefore the canopy 2 is closed by the push button 9, and the canopy 2 is provided with a part on the front side of the canopy 2. A push-button 9 having a U-shape that is elastically deformable and has an engaging slope B is formed so that it can be pushed in. When the push-button 9 is pushed in, the front portion of the canopy 2 is pushed up and the lid is opened. Since it is not necessary to provide it, the number of parts is small, and a troublesome mounting structure can be omitted, so that the structure can be simplified.
