Description

[Detailed description of the invention] "Industrial application field" The invention relates to a dispensing cap.

"Problems to be Solved by Conventional Techniques and Inventions" As a dispensing cap, a cap body having a top wall extending from the upper edge of the peripheral wall and a spout formed in the top wall, and a rear portion of the cap body There is known a lid comprising a lid body rotatably connected to the lid to cover the upper surface of the spout so as to be openable and closable. These spout caps are used by being fitted to the mouth and neck of the container body, but in order to express the unused contents, cover the spout cap or cover the entire container including the spout cap. Shrink-packing with a synthetic resin film or the like is generally performed. However, shrink packs require a high raw material cost and also require equipment for this purpose.

The purpose of the present invention is to provide a pouring cap that can express the unused contents without such special packaging, and that once opened, it can be seen that it has been opened. It is.

[Means for Solving the Problems] A cap body 2 having a spout provided in the center of a top wall 5 extending from the upper edge of the peripheral wall 4 and a lid locking tubular portion 9 erected from the outer peripheral edge thereof; The upper rear end of the cap is rotatably connected to the upper rear end of the main body 2 so that the upper surface of the cap main body can be opened and closed. And a pair of support projections 15 projecting from the front part of the peripheral wall 12 of the lid 3 at a predetermined interval, and a lower inner peripheral surface of each projection 15 is formed on an outer peripheral upper end of the cap body peripheral wall 4. The projections 15
A plate-shaped sealing member 17 is provided, which is connected on both sides via a breakable connecting rod 16 protruding from the inner surface, and a locking projection 18 protruding from the lower end of the rear surface of the member 17 is attached to the cap body peripheral wall 4.
The engaging projections 10 projecting from the upper end of the front part are irremovably pressed and engaged.

[Operation] In use, the peripheral wall 4 of the cap body 2 is fitted to the outer periphery of the mouth and neck (not shown) of the container body. At the time of opening, if the sealing member 17 is pulled down in the direction of the arrow from the state shown in FIG.
Is cut off as shown in FIG. 4, and the lid can be opened.

"Example" Hereinafter, an example of the present invention will be described with reference to the drawings.

1 to 5 show one embodiment of the present invention, in which 1 shows a pouring cap. The cap 1 is as shown in FIG.
The cap body 2 and the lid 3 are formed by integral molding of a synthetic resin.

The cap body 2 has a top wall 5 from the upper end edge of the cylindrical peripheral wall 4.
And a circular V-groove-shaped breaking portion 6 is formed at the center of the top wall 5, and a bar-like projection 7 is erected in the breaking portion 6. 6
Are broken to form a spout there.
A pouring tube portion 8 is provided on the outer periphery of the break portion 6, and a lid locking tube portion 9 is provided on the outer periphery thereof. Further, an engagement protrusion 10 is provided so as to protrude forward from an upper end of a front portion of the peripheral wall 4.

The lid 3 is provided with a thin hinge 11 on the rear upper end of the cap body 2.
The lower end of the rear portion of the cylindrical peripheral wall 12 is rotatably connected to the upper surface of the cap body 2 so as to be openable and closable.
The configuration for rotatably connecting the lid 3 to the cap body 2 is as follows.
Not only the thin hinge but also a known connecting mechanism such as a three-point hinge mechanism can be adopted. Further, a fitting tube portion 14 is fitted from the back surface of the top wall 13 extending from the upper end of the peripheral wall 12 to the inner periphery of the lid locking tube portion 9 of the cap body 2 so as to slide and fit on the outer peripheral surface. I have. The lid 3 is locked to the cap body 2 by fitting the fitting cylinder 14 to the lid locking cylinder 9. Therefore, the fitting cylinder 9 may also serve as the discharging cylinder. In this case, the fitting cylinder of the lid may be slidably fitted on the outer periphery of the cylinder.

In addition, a pair of support protrusions 15 are protruded from the lower end of the front part of the peripheral wall 12 of the lid 3 at positions sandwiching the engagement protrusions 10 at predetermined intervals. The support projection 15 is configured such that, when the lid 3 is closed, the lower end inner surface is fitted to the front outer peripheral upper end of the cap main body peripheral wall 4. The locking of the lid 3 to the cap body 2 in combination with the engagement with the cap body 2 is more stable. In addition, a seal member 17 having both side surfaces connected to each other via a breakable connection rod 16 protruding from the inner surface of each support protrusion 15 is provided integrally. The member 17 has a flat plate shape whose upper end is curved forward, and has a locking projection 18 projecting from the lower end of the rear surface thereof. The projection 18 is pressed from above the engagement projection 10 provided on the cap body peripheral wall 4. The cover 3 is sealed to the cap main body 2.

[Effects of the Invention] As described above, the present invention's dispensing cap has the above-described configuration, and thus can express the unused state of the container without requiring a special packaging such as a shrink pack unlike the conventional product. In addition, the seal member can be easily cut off, and it can be seen at a glance that the container has been opened by cutting off, and there is an advantage that it can be clearly expressed that the container is used or in use. Also, when the locking projection of the seal member is pressed and engaged with the engagement projection of the cap body, the connecting rod portion is slightly twisted and the lower portion of the seal member is engaged while projecting slightly forward. The locking projection can be reasonably engaged with the locking projection despite the depressing engagement, and there is very little risk of breakage during sealing such as inadvertent breakage of the connecting rod.
