Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a cap that is screwed onto a bottle mouth and seals the bottle mouth.

``Prior art'' Conventionally, metal caps have been widely used to seal the mouths of bottles filled with carbonated beverages, etc., and can be made airtight by combining them with gaskets. A structure like this is known.

As shown in FIG. 2, the metal cap 1 before being attached to the bottle opening includes a cap body 2 formed into a substantially bottomed cylindrical shape, and a plurality of bridges 3 at the lower end of the cap body 2. A birch fabric ring (hereinafter abbreviated as PP ring) 4 is formed integrally with the cap body 2, and a soft polyvinyl chloride resin and ethylene vinyl acetate copolymer are fitted into the top plate portion 5 of the cap body 2. It is composed of a thin disc-shaped packing 6 made of a soft material such as resin or polyethylene resin. This cap 1 has no threads formed on the outer periphery of the cap body 2, and is attached to the bottle mouth in the following manner.

First, the cap 1 is placed over the mouth of a bottle moving on a conveying device using a cap chute. Then, as shown in Fig. 3, the capping machine 7
The pressure block 8 presses the cap 1 against the bottle opening 9, and the pressure block 8 presses the peripheral edge 5a of the top plate 5 of the cap 1 to shrink the cap. Then, a female thread 13 corresponding to the male thread 12 on the outer periphery of the bottle spout 9 is formed on the peripheral wall 11 of the cap 1, and the PP ring 4 at the lower end of the cap 1 is moved to the bottle spout 9 side using the building fabric roller 14. Get involved.
As a result, the cap 1 is securely attached to the bottle opening 9, as shown in FIG.

"Problems to be Solved by the Invention" By the way, the above-mentioned conventional caps have the following problems, and their solution is desired.

As mentioned above, when the cap 1 is attached to the bottle opening 9 by the capping machine 7, for example, the bottle may be shaken accidentally, and the contents of the bottle may spill out from the bottle opening 9. It may adhere to the outer peripheral surface of cap 9 and the inner peripheral surface of cap 1. Therefore, when the cap 1 is attached to the bottle spout 9, the contents will adhere to the inner circumferential surface of the cap 1 and the outer circumferential surface of the bottle spout 9, although there are some differences. Therefore, if the contents contain a large amount of sugar, such as carbonated drinks or fruit juice, after the cap is attached, the overflowing contents will dry between the cap 1 and the mouth of the bottle, and the remaining sugar will be absorbed by the adhesive. As a result, even if an attempt is made to rotate the cap 1 for the purpose of opening it, it often happens that the cap 1 cannot be rotated and cannot be opened.

This idea was made in view of the above circumstances,
The purpose of the present invention is to provide a cap that does not interfere with the opening operation even if contents containing a large amount of sugar overflow and adhere to the area around the bottle mouth when the cap is attached to the bottle mouth. It is.

"Means for Solving the Problem" The cap according to this invention has a small hole drilled in the upper part of the peripheral wall of the cap along the circumference of the peripheral wall, and water and hot water for cleaning can be supplied through the small hole. , water vapor, etc. is injected between the inner circumferential surface of the cap and the outer circumferential surface of the bottle mouth so that the contents adhering between the cap and the bottle mouth can be easily washed away after the cap is attached. It is.

``Embodiment'' FIG. 5 shows an embodiment of the cap with a small hole for cleaning the bottle opening according to this invention. It is formed to have the same shape and dimensions as the conventional cap 1 (FIG. 2) except that holes 17 are formed therein. That is, in this cap 15,
The bridge 18..., PP ring 19, top plate part 2
0, the packing 21, the surrounding wall part 22, etc. are the cap 1
Bridge 3..., PP ring 4, top plate part 5,
It is formed to have the same shape and dimensions as the packing 6, peripheral wall portion 11, etc.

As shown in FIG. 1, the small holes 17 are connected to the upper ends 23a of the female screws 23 formed in the peripheral wall 22 in correspondence with the male screws 12 of the bottle spout 9 when the cap 15 is attached to the bottle spout 9. , are bored at equal intervals along the circumference of the peripheral wall between the gasket 21 fitted inside the top plate portion 20. Furthermore, as shown in the figure, these small holes 17 are formed by making a cut line in the upper part of the peripheral wall part 22 along the circumference of the peripheral wall, and making the upper part of the cut line bulge inward. The opening surface of the small hole 17 is approximately parallel to the top plate portion 20.

"Function and Effect" Therefore, in FIG. 1, if water, hot water, steam, etc. are injected into the small holes 17 from diagonally above the cap 15, these water, etc. will smoothly flow onto the outer peripheral surface of the bottle mouth 9. and the inner peripheral surface of the cap 15. Small hole 17... to cap 15
Water, etc. injected between the inner circumferential surface and the outer circumferential surface of the bottle spout 9 flows down along the male thread 12 of the bottle spout 9 and adheres between the inner circumferential surface of the cap 15 and the outer circumferential surface of the bottle spout 9. The sugar contained therein is washed away and flows out of the cap 15 from the lower end of the score 24 or PP ring 19 forming the bridge 18.

As a result, since there is no sugar attached between the inner circumferential surface of the cap 15 and the outer circumferential surface of the bottle mouth 9, the cap 15
There is no obstacle to opening the package, and the opening operation can be easily performed.

If a plurality of small holes 17 are provided as in this embodiment, they can also serve as KNURLs used to prevent slipping when opening the package.

Further, in the above embodiment, the small hole for cleaning the bottle mouth was formed so that its opening surface was almost parallel to the top plate of the cap, but the shape is not limited to this, and the hole can be formed between the inner circumferential surface of the cap and the outer circumference. Other shapes may be used as long as they communicate with the surface.

As explained above, the cap with a small hole for bottle mouth cleaning according to this invention has a small hole bored in the upper part of the peripheral wall of the cap along the circumference of the peripheral wall, so that the bottle opening can be used for cleaning through the small hole. Inject water, hot water, steam, etc. between the inner circumferential surface of the cap and the outer circumferential surface of the bottle mouth,
Contents that stick to the space between the cap and the bottle mouth after the cap is attached and that obstruct the opening of the cap can be easily washed away. This can prevent the package from becoming difficult to open.
