Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an inner plug for pouring.

[0002]

[Prior art] [Problems to be solved by the device]

 It is known that a spouting inner plug has a cylindrical shape with a lower end surface opening in which a top wall extends from an upper edge of a peripheral wall and a spout is formed in a central portion of the top wall. These inner plugs are attached to the container body by fitting a peripheral wall on the upper outer periphery of the mouth neck of the container body, and are covered with an outer cap that is detachably fitted on the lower part of the mouth neck. Used. Also, when it is not used at the time of manufacture, a plastic film or the like is attached to the top surface of the top wall to close the spout.

The present invention proposes a pouring inner plug with an outer cover that is difficult to remove when not in use and can be easily removed when removing.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the stopper according to the present invention has a top wall 5 extending from the upper edge of the peripheral wall 4, and a plug body 2 formed with a spout hole 6 at the center of the top wall 5, and the main body. 2 of the peripheral wall 4 and the outer wall 3 of the synthetic resin film, which covers the area from the outer surface of the peripheral wall 4 to the upper surface of the top wall 5, and is provided at the front position of the peripheral wall 4 of the plug body. A tongue piece 12 for finger hanging is formed by providing an opening 11 opened from the lower end edge, and a pair of break lines 13 longitudinally cutting the outer cover material 3 are provided rearward from both base ends of the tongue piece 12. Configured

[0005]

[Action]

 If the tongue piece 12 for finger hanging is rolled up and grasped and then pulled backward, the outer skin material 3 is broken at each break line 13 and the outer skin material 3 is separated into three parts and can be easily removed.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The inner plug 1 for pouring of the present invention comprises a plug body 2 and an outer cover material 3 shrink-wrapped on the body 2.

The plug body 2 is made of a synthetic resin such as polyethylene, and has a cylindrical shape with a lower end surface opening in which the top wall 5 extends from the upper edge of the peripheral wall 4, and the top wall 5 has a central opening for pouring. Through holes 6 are formed. Further, a seal cylinder 8 for vertically fitting in a liquid-tight manner is vertically provided on the inner surface of the mouth / neck portion 7 of a container body or the like to be attached at a position spaced apart from the peripheral wall 4 on the back surface of the top wall 5, At the lower end of the inner circumference of the peripheral wall 4, there is provided a ridge 9 which engages with a ridge provided on the outer surface of the pouring portion such as a container.

As the outer cover material 3, a cover body 10 formed of a synthetic resin film such as polypropylene or polyvinyl chloride as shown in FIGS. 3 and 4 is used. It is mounted by a well-known shrink pack method so as to densely cover a portion extending from the outer surface to the upper surface of the top wall 5.

The outer cover member 3 attached to the stopper body 2 has a rectangular tongue piece 12 for hanging a finger by providing an upwardly U-shaped opening 11 at the front surface of the peripheral wall thereof. Further, a pair of break lines 13 formed by perforations, thin-walled lines, etc. that longitudinally cut the outer cover material 3 back and forth from both base ends of the tongue piece 12 are formed.

The cover body 10 projects a rectangular tongue piece forming portion 15 forward from a front portion of a ring-shaped base portion 14, and further extends the base portion 14 rearward from both base ends of the tongue piece forming portion 15. A rupture line 13 is formed that runs vertically. Further, a circular window hole 16 having a predetermined size is formed at a target position corresponding to each of the break lines 13.

After inserting the stopper main body 2 into a predetermined position in the base portion 14 of the cover body 10 thus configured, the film is shrunk by a known method to obtain the inside stopper 1 of the present invention.

As shown in FIG. 2, the inner plug 1 configured as described above is fitted with a peripheral wall 4 on the outer periphery of the mouth / neck portion of the container body, and the outer surface of the seal tube 8 is fluid-tightly fitted on the inner periphery of the mouth / neck portion 7. The outer cover member 3 on the top wall 5 is pressed by the top wall 18 of the outer cap 17 screwed onto the lower part of the outer periphery of the mouth / neck 7 so that the pouring hole 6 is liquid-tightly closed. ing.

[0014]

[Effect of device]

 As described above, the pouring plug of the present invention has good liquid-tightness because the portion from the lower surface of the peripheral wall of the stopper body to the upper surface of the top wall through the outer surface of the peripheral wall is densely covered with the outer cover material made of the synthetic resin film. It is hard to come off by external force.

Further, a tongue piece for finger hooking is formed by providing an opening at the front portion of the peripheral wall of the plug body, the opening portion opening from the lower end edge, and a pair of break lines that vertically cut the outer skin material from the base end portion of the tongue piece. Since it has been extended, if you roll up the tongue and pull it backwards during use, the outer skin will easily come off and the pouring hole will open.
