Description

[Detailed Description of the Invention] The present invention relates to a decorative cap attachment that is attached to a roll-on pilfer-proof cap (hereinafter referred to as PP cap) of a bottle to give the bottle an aesthetic appearance.

Conventionally, high-quality bottles such as wine and whiskey have been made with expensive, beautiful-looking caps such as glass, while cheaper bottles have inferior appearance, but are suitable for mass production and can be manufactured at extremely low prices. PP
Caps etc. were used.

Caps made of glass or the like are difficult and expensive to manufacture, and because they use cork or the like, they have the drawback of being cumbersome to handle, such as replacing the cap during storage and use after opening.

This invention is attached to an extremely inexpensive bottle with a PP cap, which makes it easy to open the PP cap, and also makes the bottle beautiful in appearance and can be made into a high-class product. The purpose is to provide cap attachment.

The decorative cap attachment according to the present invention is characterized by a circular hole with a bottom that can be fitted onto the PP cap, and when it is fitted onto the PP cap, it slightly bites into the upper circumferential surface of the cap and locks into place. The present invention has a plurality of locking portions arranged on the inner circumferential surface of the bottomed circular hole, and an external shape that gives an aesthetic appearance.

With this structure, the PP cap can be opened by attaching it to an inexpensive bottle with an inferior appearance and fitting it onto the PP cap and locking it with the locking piece during use. Not only is it easier to stopper the bottle, but it also gives the bottle a more aesthetic appearance.

Preferred embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows a PP cap 1, which is screwed into the mouth of a bottle 2 and is squeezed under the annular ridge formed at the rear mouth to form a reduced diameter part 1a, making it impossible to unscrew it. It is said to be strong enough to open the bottle.
Unscrew the PP cap and break the perforation-like intermittent cutting/sliding portion 1b provided on the PP cap 1 at the top of the annular ridge at the mouth of the bottle 2 to form the reduced diameter portion 1a into the PP cap body 1c. must be separated from In this manner, once the cap is opened, the reduced diameter portion 1a is separated, so that it can be clearly seen that the cap has been opened, which is useful for pilfer-proofing.

FIG. 2 shows a preferred embodiment of the decorative cap attachment according to the present invention. This cap attachment has a bottomed circular hole 3 that fits into the PP cap 1 shown in FIG. A shoulder portion 3a is formed which comes into contact with the shoulder portion 3a.

Due to the features of the present invention, the shoulder 3 on the inner peripheral surface of the circular hole 3
A plurality of locking portions 3b are formed to protrude inward at a portion close to a, that is, at a position corresponding to the upper end circumferential surface 1d of the PP cap 1 when fitted to the PP cap 1, and these locking portions 3b When fitted to the PP cap 1, it slightly bites into the upper circumferential surface 1d and firmly fixes the cap attachment to the PP cap 1. Therefore, the PP cap 1 can be easily opened by rotating the cap attachment in the unscrewing direction of the PP cap 1.

The cap attachment is made by molding plastic or the like, and the locking part 3b is attached by insert molding a thin metal strip 3c made into an arc shape at the same time as the cap attachment is molded, as shown in FIG. It is better. As mentioned above, the external shape of the cap attachment can be given various shapes and colors to give it an aesthetic appearance.

When storing the cap attachment, a spacer piece is interposed on the PP cap 1 so that the locking part 3b is secured to the PP cap.
Fit the cap 1 so that it does not dig into the upper end of the cap 1. When opening the cap, remove the spacing piece, fit it to the PP cap 1, and push it in. Push it into place to secure it in place.

FIG. 4 shows a modification of the locking part 3b in FIG. 2,
The locking portion 3b' is formed by using a wire 3c' such as a piano wire instead of the arc-shaped metal band 3c.

FIG. 5 shows still another modification, in which when the bottom of the circular hole 3 is flat, a cutting and bending protrusion 3b'' is formed by insert molding on the bottom, so that the protrusion 3b'' serves as a locking part. A metal disk 3c'' is used.

Figures 6-9 show another modification, in which the locking part is formed separately from the cap attachment body and is a protrusion bent from the periphery of the metal disc 4 fixed deep inside the circular hole 3. 4a is shown.

At the inner corner of the circular hole 3 of the cap attachment body, small protrusions 3d are formed at intervals as shown in FIG. 6, and on the metal disc 4, as shown in FIG. A locking protrusion 4a is formed by cutting and bending at the center of the meshing tooth portion 4b and the tongue piece 4c, and the periphery is bent so that it can be fitted into the circular hole 3 as shown in FIG. , the tooth portion 4b is firmly engaged with the protrusion 3d by pushing it deep into the circular hole 3. As a result, the locking protrusion 4a projecting inward serves as the locking portion described above. FIG. 9 shows the combined state. In this embodiment, the shape of the cap attachment main body is a cup-like shape, but this outer shape can be formed arbitrarily.

As mentioned above, according to the present invention, it can be manufactured at low cost,
Moreover, a cap attachment is provided that can be attached to an inexpensive bottle with a PP cap to give it a high-class and beautiful appearance.
