Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a one-touch cap which has a nozzle barrel for dispensing that can be raised and lowered and which can be opened and closed with one touch by driving the nozzle barrel.

``Prior art'' This type of conventional cap has a lid-like member pivoted at its midpoint and disposed on the upper surface of the cap body, with one end serving as a push button, and the other end having a nozzle tube opened laterally and outwardly. The nozzle tube is normally closed by pressing down on the rod stopper on the top of the cap body, and when dispensing, the push button is pressed down and the nozzle tube is driven upward in a seesaw style to open the nozzle tube.

``Problems to be solved by the invention'' With the above structure, the nozzle tube rotates around the pivot point of the lid-like member, so there is a problem with the spout seal, and when the cap is open, the area around the cap body This has the disadvantage that the contents are difficult to pour out, and dripping liquid flows down onto the top surface of the cap body, staining the top surface.

The present invention aims to obtain a one-touch cap which eliminates the above-mentioned drawbacks by providing a pivotal structure between the nozzle cylinder and the push button so that the nozzle cylinder can be raised and lowered approximately vertically.

``Means for Solving the Problems'' The one-touch cap of the present invention extends the peripheral wall 4 upward from the top wall 5 and has a storage recess 6 in the upper surface of the top wall 5.
, and an engagement cylinder 7 is erected from the front side peripheral part of the upper surface of the top wall 5, and from the top wall 5 within this engagement cylinder 7,
A cap body 1 has a rod stopper 9 with a tapered portion 8 at the upper end, a small pouring hole 10 near the base of the rod stopper 9, and a cap body 1 which is in the shape of an upside-down dish and has a storage portion 11 on the front side. A lid is formed with a notch, provided with upward engaging edges 12, 12 on both sides of the lower edge of this housing part 11, pivoted on both left and right sides, disposed in the housing recess 6, and has a push button 13 on the rear side. The member 2 is connected to the rectangular cylindrical part 14 whose front opening is in contact with the inner surface of the extended peripheral wall 4a, and is fluid-tightly fitted into the engagement cylinder 7 and loosely fitted into the rod stopper 9. A cylinder 16 having a stopper seat 15 connected to the tapered part 8 at the upper end of the rod stopper 9 is vertically provided on the inner periphery of the upper part, and the rectangular cylindrical part 14 allows play in the storage part 11 of the lid member 2 and makes it easy to remove it. It consists of a nozzle tube 3 that can be attached.

"Function" In the above, normally, as shown in FIG. , the nozzle tube 3 is closed, the small pouring hole 10 is closed, the upper opening of the nozzle tube 3 is in contact with the inner surface of the extended peripheral wall 4a, and the lid is closed. The top surface of the member 2 is substantially flush with the upper end of the extended peripheral wall 4a.

Here, when dispensing the contents, the push button 13 is pressed down. Then, as shown in Fig. 3a and b, the lid member 2
The front part of the nozzle tube 3 is lifted upward, and the nozzle tube 3 is thereby opened and communicated with the inside of the container body through the small pouring hole 10.
Pouring becomes possible.

In this case, the nozzle tube 3 is engaged with the lid member 2 with some play, so even if the lid member 2 is tilted, the nozzle tube 3 is guided by the engagement tube 7 and moves upward almost vertically. The upper opening is located at the same periphery of the cap body 1 as when the cap is closed, making it easy to pour out.

In addition, when closing the cap after dispensing, the front part of the lid member 2 or the nozzle tube 3 may be pushed down. That is, the nozzle tube 3 can be opened and closed with one touch.

``Embodiment'' The one-touch cap of the present invention includes a cap body 1, a lid member 2 pivotally attached to the upper surface of the cap body 1, and a nozzle tube 3 engaged with the front part of the lid member 2 with play. Consisting of

The cap body 1 is screwed onto the mouth and neck of the container body (not shown), and a protrusion 17 is erected in the left-right direction at the center of the upper surface of the top wall 5. In addition, the extension peripheral wall 4
The rear half of the upper end becomes gradually lower toward the rear.

The lid member 2 has pins 1 protruding from both left and right outer surfaces.
8 and 18 are pivotally installed in the storage recess 6, and a partition wall 19 is provided vertically from the back surface connecting these two pins 18 and 18, and a thin elastic plate 20 is provided from the lower edge of this partition wall 19 to the side contact with the upper part of the protrusion 17. is hanging down. This elastic plate 20 is repelled by the protrusion 17 every time the tap is opened or closed, and generates an operation confirmation sound. Also, the storage section 11
The front part of the hanging peripheral wall 21 is cut out and opened to the front, so that the nozzle tube 3 can be slid in and out from the front.

The nozzle cylinder 3 has an upper rectangular cylindrical portion 14 formed into a cylinder 16.
This rectangular cylindrical part 14 is placed on the engagement edges 12, 12 and is stored in the storage part 11 with play in the front and rear and up and down directions, so that the lid member 2 can push down the push button 13. It is designed so that it can maintain an almost vertical state even if it is tilted.

FIG. 4 shows another embodiment. In this example, the storage section 11 at the front of the lid member 2 is opened to the upper surface, so that the upper surface of the nozzle tube 3 is exposed, and the nozzle tube 3 is opened to the upper surface of the lid member 2. It is possible to color code.

Each of the above parts is molded and manufactured from synthetic resin material.

"Effect of the invention" As described above, in the present invention, the nozzle tube 3 is separate from the lid member 2 and engaged with the lid member 2 with some play, so even if the lid member 2 is tilted when opening, the nozzle tube 3 can be raised almost vertically, and the upper opening for dispensing is located at the peripheral edge of the cap body 1 as when the cap is closed, making it easy to pour out and preventing dripping liquid from flowing down onto the top surface of the cap body 1 and contaminating it. It can also be avoided. Further, since the nozzle tube 3 moves up and down vertically, it is not inclined with respect to the engagement tube 7, and therefore, the sealing with the rod stopper 9 and the small pouring hole 10 can be ensured.
