Description

[Detailed explanation of the idea] "Industrial application field" This case concerns cans.

"Prior Art" In the invention of JP-A No. 52-148389, the can body is formed of a material that is easily broken, such as synthetic resin, and the bottom surface of the small disc-shaped knob is formed on the top wall of the can body 1. A can was formed in such a way that the glued portion of the top wall of the can body was opened by threading the top wall of the can body by turning the knob.

"Problems to be Solved by the Invention" The conventional can described above was inconvenient because once it was opened, the opening could not be closed again.

The present invention aims to eliminate such drawbacks and provide a can whose opening can be reclosed.

"Means for Solving the Problem" The opening 11 of the can body is closed with a plastic lid body 21 with a plastic-coated aluminate 22 adhered to the lower surface, and the lower end is covered with plastic from an appropriate place on the plastic lid body. Coated aluminum sheet 2
The spouting tube 24, which is closed with the spouting tube 2, is erected, and the stopper 3 is detachably and lowerably attached to the inside of the spouting tube, and as the stopper is lowered, the plastic-coated aluminum sheet at the lower end of the above-mentioned spouting tube 24 is removed. 22 was formed to have a fracture opening.

"Operation" When the stopper 3 is screwed down or lowered from the state shown in FIGS. 3 and 7, the plastic-coated aluminum sheet 22 breaks open along the inner periphery of the spout tube 24 at the blade 36 or the inclined lower end 32a. be done. Next, the stopper 3 is removed and the stored contents are poured out from the pouring tube 24.
Thereafter, the stopper 3 can be used as a closure for the spout tube 24 to seal the spout tube 24.

"Embodiment" First, the first embodiment shown in FIGS. 1 to 4 will be described. Reference numeral 1 denotes a cup-shaped can body with a rectangular planar shape, and the can body is as shown in FIG. 3. ,
A plastic-covered aluminum sheet 12 is laminated as an outer layer, and a plastic sheet 13 is laminated as an inner layer. As shown in the enlarged cross-sectional view of FIG. 4, the plastic-covered aluminum sheet 12
A thin plastic coating 12 is applied to both the front and back sides of 2a.
b, 12b are layered. Note that the plastic-coated aluminum sheet 12 and the plastic sheet 13 may be reversed inside and out.

2 is a lid body that airtightly closes the opening 11 of the can body 1, and this lid body is made of plastic lid body 21.
A plastic-coated aluminum sheet 22 is laminated and integrated on the lower surface, and the peripheral edge 23 is formed into a hook-shaped cross section, which is fitted onto the rim 11a of the can body opening 11, and then fixed by suitable welding means. They are integrated by welding.

In addition, a spouting tube 24 whose lower end is closed with the plastic-coated aluminum sheet 22 and has a thread 25 on the lower half of the inner periphery is integrally provided at one corner of the upper surface of the lid body 21, and a plug is attached to the spouting tube. The body 3 is detachably attached.

The stopper body 3 is integrally molded from a suitable synthetic resin, and has a stopper cylinder 32 that fits into the spout cylinder 24 hanging from the top wall 31, and the upper half outer periphery of the stopper cylinder 32 is connected to the spout cylinder 24. It is formed to fit into the inner upper half, and a thread 33 is provided on the outer periphery of the lower half so as to be threaded into the thread 25 on the inner lower half of the pouring tube 24, and protrudes outward from the top wall 31. A knurling 35 is formed on the outer periphery of the flange 34, and a triangular pointed blade 36 is hung from a suitable position at the lower end of the spouting tube 32. Note that a tab piece may be provided protruding from the upper surface of the top wall 31, as shown by the two-dot chain line in FIGS. 2 and 3.

5 to 8 show a second embodiment. In this case, the specific structure of the spout tube 24 and the stopper 3 differs from the previous example, but the other parts are the same as the previous example.

The pouring tube 24 has a pair of recesses 26, 26 formed with appropriate widths in the upper half of its inner periphery, and a small engagement protrusion 27 immediately below the recesses 26, 26.

The stopper 3 abuts on the upper half of the outer periphery of the stopper tube 32 at a proper location and against the remaining portions 28, 28 of the upper half of the inner circumference of the spout tube 24, which do not form the recesses 26, 26, and prevents the stopper from descending. , and a bulging part 3 that fits into the recesses 26 and 26 by rotation to enable the stopper to descend.
7, 37, an engagement recess 38 that engages with the engagement protrusion 38 is formed at a proper location corresponding to the engagement protrusion 27, and the lower end of the stopper cylinder 32 is inclined, so that the inclined lower end 3
2a is replaced with a blade. Further, the flange 34 that protrudes outward from the top wall 31 is not provided with a knurl, but instead has a knob 39 that protrudes further outward.
has been established.

"Effect of the invention" The spout tube 24 is made to stand up from the plastic lid main body 21, and the stopper 3 is installed in the spout tube in a detachable and descendable manner, and when the stopper is lowered, the spout tube 24 Since the plastic-covered aluminate sheet 22 at the lower end is formed so as to be opened by breaking, the plastic-covered aluminum sheet 22 can be easily broken simply by lowering the plug body 3, and after the break-opening, the plug body can be opened. Therefore, it is convenient to be able to close the spout tube 24.
