Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mouth structure of a glass bottle which can be fitted with a pill-proof cap (hereinafter referred to as a PP cap) or a steal cap.

[0002]

[Prior art]

 Conventionally, the cap of a glass bottle that is capped with a cylindrical metal (mainly made of aluminum) with one side open and then rolled on (wrapped) along the outer shape of the bottle is used. It is generally used in capping processes for water, sake, etc., and the bottle mouth is selected so that the shape of the bottle mouth fits the standard size of the PP cap or stell cap used. are doing. For example, for a 30x44 stell cap, the mouth of the structure shown in Fig. 2 is applied to a glass bottle, and for the pill faproof 30 special deep (PP30SD) cap, the mouth of the structure shown in Fig. 3 is made of glass. It is applied to bottles.

However, comparing the main dimensions involved in the capping function in the structure of the mouth portion of the glass bottle applied to the above-mentioned 30 × 44 stell cap and PP30SD cap, the difference is small. Nevertheless, each cap could only be used with a bottle mouth that had a mouth structure adapted to it.

For this reason, a bottle manufacturer needs to manufacture two types of products and manage the products with only a slight difference in the mouth portion. On the other hand, the bottle user side, for example, uses the same bottle. However, there is a problem in that it is not possible to select the type of cap depending on the variation of the contents, etc., and the trouble of having to separately manage and use each bottle as with the bottle manufacturer arises. There is. Therefore, in order to eliminate such annoyance, both the glass bottle manufacturer and the user have a growing demand for a glass bottle having a mouth structure capable of sharing the same size of the stell cap and the PP cap. As a result of examination, the present invention has been reached.

[0005]

[Problems to be solved by the device]

 The present invention has been completed in order to solve the above-mentioned problems and to provide a mouth structure of a glass bottle in which a cap can be attached regardless of whether a PP cap or a stell cap having a similar size is selected.

[0006]

[Means for Solving the Problems]

 The present invention made in order to solve the above-mentioned problem is that the taper, the tip R, and the root R of the lower end surface of the bead of the bottle neck of the glass bottle having the structure for mounting the stell cap are attached to the stell cap most. Make the skirt shape the same as the mouth of a glass bottle for a pill-proof cap of similar size, and measure the distance from the mouth of the bottom edge of the bead to the skirt from the mouth of the pill-proof cap. It is characterized by being the same as.

That is, in the mouth portion method of the glass bottle of the PP cap and the stell cap having similar dimensions, non-identical dimensions such as the outer diameter of the mouth and the screw thread diameter are common dimensions of the permissible dimension, The bottle skirt remains the same as before and the lower end surface of the bead is changed to the shape of the bottle cap for PP cap and the distance from the mouth is the same, and the function is as a bottle cap skirt for PP cap. It is provided on the end face.

【Example】

 The present invention will be described below with reference to the illustrated embodiments. 1G is a front view showing the mouth structure of the glass bottle of the present invention in which either the stell cap 100 used in FIG. 2 or the PP cap 200 used in FIG. 3 can be mounted. Yes, FIG. 1 (b) is an enlarged cross-sectional view of the beat 4 '. 2 is a front view of the structure of the mouth of the glass bottle to which the 30 × 44 stell cap is applied, and FIG. 3 is a front view of the structure of the mouth of the glass bottle to which the P P30SD cap is applied. Are close to each other. Table 1 shows the dimensions of the main mouth portion related to the capping function of the present invention of FIG. 1 and the glass bottles of FIGS. 2 and 3.

[0009]

[Table 1]

When a steal cap having a lower end of the cap up to the vicinity of the neck 6 ′ is attached to the mouth portion G of the glass bottle of the present invention, the mouth outer diameter 1 and the screw thread diameter 2 are shown in FIG. Since the outer diameter 101 and the thread diameter 102 of the cap bottle mouth 100 are set within the permissible dimensions, and the skirt diameter 3 and its shape are the same as the conventional skirt diameter 103 and its shape, they are known. The lower end of the cap fits to the controlled neck diameter of 6 parts by being tightened by the rollers of the capper along the lower surface shape of the screw part 2'and the skirt 3 '.

On the other hand, when the PP cap is attached, a taper 9 having the same shape as the lower end surface of the skirt 203 ′ of the PP cap bottle mouth 200 as shown in FIG. The tip R10 and the root R11 are formed at the same distance 7 as the distance 207 from the top of the PP cap bottle mouth 200, and the mouth outer diameter 1, the thread diameter 2 and the beet lower diameter 5 are the outer diameter of the PP cap 200. Since it is set within the allowable dimensions of 201, screw thread diameter 202 and skirt lower diameter 205, the roller can be wound and tightened along the shape of the screw portion 2'and the lower surface of the bead 4 '. When using the PP cap, the neck diameter 6 does not participate in the capping function. Further, it goes without saying that the screw cutting start position 8, the screw pitch P, and the screw width W are the same and there is no hindrance to the capping.

A glass bottle having a mouth structure having the dimensions shown in Table 1 was produced, and a 30 × 44 stell cap and a PP30ED cap were mounted on the cap with a known roll-on capper. Also, as a result of checking the example and its state by attaching the special caps to the glass bottles having the respective special openings in the same manner, the results at the time of capping, the capped state of the capped caps and the bottle caps were confirmed. It was possible to obtain exactly the same state, the opening torque, etc.

From the results of Example 1 above, the glass bottle bottle that can be fitted with the stell cap and the PP cap of similar size is 31.5 × 44 stell cap and PP31.5SD cap with the existing standard mouth size. It is also applicable to 31.5 × 44 stell cap and PP 31.5SD cap, and the performance and function were confirmed by producing glass bottles. As a result, similar to Example 1, the same bottle size was used. It was confirmed that the above two types of caps, the Stellcap and the PP cap, can also be applied. Tables 2 and 3 show the dimensions of the main mouths involved in the capping function of the glass bottles of the second and third embodiments of the present invention.

【The invention's effect】

 As described above, the bottle bottle structure of the present invention has a structure in which the cap can be attached regardless of which of the widely used stell cap and PP cap that are currently widely used is selected. For a person, it is possible to unify the production of two kinds of bottles with a slight difference in the conventional mouth shape with one type, and there is no need to change the mold for changing the product type, which increases the production lot and the productivity associated with it. Improvement and stability and simplification of product management can be achieved. In addition, since the mouthpiece drink of the present invention can be used as it is, a mold other than the existing mouthpiece can be used as it is, so that the bottle shape having the mouth structure of the present invention can be easily switched.

On the other hand, even for bottle users, the management of bottles, which is one of the materials, is simplified. For example, even if the filling is changed in the same bottle, the stell cap and the PP cap can be freely selected. It has the advantage that it can be used, and it is easier than ever to add variations to the product.

Therefore, the bottle bottle structure of the present invention can bring a very beneficial effect not only to the manufacturer of the glass bottle but also to the user in terms of production and management. Is extremely large.
