Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cap seal mounting structure capable of surely determining whether or not a cap of a bottle container is opened.

(Prior Art) As is well known in the art, in the case of a bottle container, for example, Jpn.
As described in JP-A No. 718 and Japanese Utility Model Laid-Open No. 53-28057, there are many means for fitting a cap seal on a bottle cap.

As a structure in which these conventional cap seal mounting structures are combined, as shown in FIG. 6 (a), the cap 4 screwed onto the bottle container 1e and the cap seal 7e on the bottle container portion below the cap 4 are attached. Although it may be fitted, the cap seal 7e is only provided with perforation lines 8 for breaking and opening.

(Problems to be solved by the invention) Therefore, this kind of cap seal can be used not only for sealing the bottle, displaying an advertisement, etc., but also for determining whether or not the bottle container is opened. That is, the cap seal is broken when the cap is opened, which makes it difficult to attach the cap seal to the bottle container again, which may cause drugs and the like to be improperly put into the bottle container for sale. It originally has a function that can prevent situations.

However, if the cap seal of the Japanese Utility Model Publication No. 4528718 is fitted to a container in which the surface of the bottle container 1e below the mounting position of the cap 4 is formed into a smooth surface state, the surface portion concerned Since the lower side of the cap seal 7e is only fitted to the cap seal 7e, if the cap seal 7e and the cap 4 are gradually rotated by heating the cap seal 7e or the like, the cap seal 7e can be opened without breaking. It can be plugged.

As shown in FIGS. 6 (a) and 6 (b), the cap seal 7e is provided in the container described in Japanese Utility Model Laid-Open No. 53-28057, that is, at least one recess 10e on the outer peripheral surface of the bottle container 1e. Even if it is fitted over the substantially annular projection 10 having the above-mentioned shape, it is rare that it completely bites into the incomplete portion 10e and is brought into close contact with it at the time of thermal contraction. In many cases, it is contracted in a slackened shape, and a hollow gap 11 is formed between the recess 10e and the cap seal 7e.

Therefore, if the perforation line 8 is to be broken by the projection 10, unless the perforation line 8 is positioned exactly at the cutout portion 10e, the cap seal slips during rotation and is easily opened.

Therefore, it may be indispensable to position the perforation line 8 in the cutout portion 10e, but it is very difficult to position the perforation line 8 in terms of the fitting work of the cap seal.
As shown in the figure (b), when it is located on the protrusion 10,
After that, if the cap seal 7e is gradually rotated together with the cap 4, the cap can be opened without breaking the cap seal 7e.

Therefore, in the conventional case, there has been a problem in preventing mischief and crime such as improperly injecting a drug or the like into the bottle container and re-applying the cap and the cap seal to disguise the bottle container as an unopened bottle container.

Therefore, the purpose of the present invention is to enhance the crime prevention function as compared with the conventional one, by making sure that the cap seal is always broken when the bottle container is opened and cannot be attached again. Is.

(Means for Solving the Problem) The present invention was devised in view of the fact that the cap seal must be rotated when opening the cap in a bottle container having the cap screwed therein. The above-mentioned conventional problems are solved by devising the shape of the bottle container so that the bottle container is always broken when it is rotated.

That is, according to the present invention, the cap 4 screwed to the rim portion 2 of the bottle container 1 and the uneven step portion projecting on the outer peripheral surface of the bottle container 1 below the mounting position of the cap 4 are provided. 5, a tubular cap seal 7 is fitted over both of them, and a cut guide line 8 for cutting is vertically engraved on the cap seal 7 in a longitudinal direction to form a cap seal for a bottle container. In the mounting structure, the peripheral surface portion of the cap seal 7 that covers the step portion 5 is provided with a plurality of longitudinally engraved sewing machines that are hooked and broken by the step portion 5 when the cap seal 7 rotates. The line of sight 8a is a cap seal mounting structure for a bottle container, which is provided separately from the cutting guide line 8 at appropriate intervals.

(Operation) In the cap seal mounting structure characterized by the above configuration, if the cap 4 and the cap seal 7 are rotated while the bottle container 1 is not opened, a concave and convex shape protruding in the outer peripheral direction is formed. Any one of the perforation lines 8a provided in the vicinity of the step portion 5 of the cap seal 7 is hooked and locked on the step portion 5, and at least one of the perforation line 8a is always broken by the contact force thereof. It will be. Therefore, it is impossible to rotate and open the cap 4 without breaking the cap seal 7.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 is a bottle container made of glass or the like for storing drinking water, and a male screw portion 3 is provided on a rim portion 2 on an upper end side thereof, and a screw cap 4 is screwed and attached thereto. . Reference numeral 5 denotes a step portion as a convex portion projectingly provided on the bottle container surface portion below the male screw portion 3 of the bottle container 1. The step portion 5 corresponds to the bottle container surface as shown in FIGS. 2 and 3. For example, a total of four places are provided so as to form a discontinuous uneven shape in the outer peripheral direction.
In addition, one side surface 5a of each step portion 5 has a concave peripheral surface 6 between the step portions 5,5.
In contrast, the other side surface 5b is formed so as to be gently inclined with respect to the peripheral surface 6 of the concave portion.

Reference numeral 7 denotes a cylindrical cap seal made of a thin heat-shrinkable synthetic resin material, and the cap seal 7 is fitted over the cap 4 and the step portion 5 of the bottle container 1 so as to extend over both positions. It is heat-shrinked, and the lower side thereof is fitted so as to cover the outer surface portion of each step portion 5, the outer peripheral surface 6 of the concave portion, etc., as shown in FIG. Reference numerals 8 and 8 denote cut-off guide lines made of perforations for opening / separating, which are formed in parallel with each other along the longitudinal direction of the cap seal 7, and 9 indicates an opening provided at an upper portion between the guide lines 8 and 8. The tab for use is shown. Reference numerals 8a, 8a ... Show other perforation lines formed on the lower side of the outer peripheral surface of the cap seal 7 and on the peripheral surface portion covering the step portion 5 at a predetermined interval.

Although the present embodiment has the above-described structure, first, in the case where the cap 4 is to be opened without breaking the cap seal 7 in the closed state shown in FIG. The cap 4 must be gripped and rotated from above the cap seal 7.

Then, when a rotational force in the direction of arrow a is applied to the cap seal 7 in FIG. 2, the portion of the cap seal 7 covering the one side surface 5a of the step portion 5 and the vicinity thereof is changed to the one side surface 5a.
Therefore, any one of them is always broken by the perforation line 8a or the cutting guide line 8 located in the vicinity of the relevant portion. Especially, as perforations, not only the two cutting guide lines 8 and 8 for dividing but also a plurality of separate perforation lines 8a
... is engraved, and one side 5a of the step 5 is cap seal 7
Since they are opposed to each other in the rotation direction, even if a hollow gap is formed in the portion of the cap seal 7 that covers the one side surface 5a to cause slack, Even if the cutting guide lines 8 and 8 are located in the above, since a plurality of perforation lines 8a are provided at appropriate intervals, at least one of the perforation lines 8a is caught in any step portion 5 and the cap seal 7 The breakage becomes more reliable. Also,
Since the cap seal 7 is pulled upward during the opening operation, the cap seal 7 has a convex step portion 5.
On the other hand, the force of abutting from the lower side promotes the breakage of the cap seal 7.

Therefore, in the case of the above cap seal mounting mode, the cap seal 7 is always broken when the cap is opened, and it becomes impossible to remount the cap seal 7 after the opening operation. This proves that the bottle container has been opened once.

In addition, in the above-mentioned embodiment, the bottle container is provided with the projecting step portion having the predetermined shape in four places in total, but the present invention is not limited to this. The number of the step portions 5 may be increased or decreased to any other number, and for example, only one convex step portion 5 may be provided as shown in FIG. Even in this case, any one of the plurality of perforation lines 8a is located in the vicinity of the step portion 5, and the perforation lines 8a are caught and broken during rotation.

Further, the concrete shape of the stepped portion 5 can be freely changed to various shapes as shown in (b) to (d) of the same figure. Furthermore, as shown in (e) of FIG. It may be part 5.
In order to ensure that each step 5 and the cap seal 7 are caught, it is preferable that the side surface of the step 5 be an acute angle, but even if the surface shape is rounded as shown in FIG. The purpose of the invention can be achieved.

As described above, the specific number and shape of the stepped portion 5 according to the present invention can be arbitrarily changed, and the point is to form a discontinuous convex portion or concave portion in the outer peripheral direction of the bottle container 1. It suffices that it is formed, and the formation position thereof may be below the mounting position of the cap 4.

Further, the present invention is not limited to the specific configuration of the cap seal 7 as in the above embodiment. The cutting guide wire 8 for dividing does not necessarily have to be provided with a plurality of lines as in the above-described embodiment, and may have only one line. Further, the cap seal 7 does not have to be fitted so as to cover the entire surface of the cap 4. When the adhesion of the cap seal 7 to the cap 4 is large, the cap seal 7 may be partially fitted to the cap 4 as shown in FIG. 5, for example.

The point is that any one of the perforation lines 8a or the cutting guide line 8 is fitted when it is fitted over both the cap 4 and the bottle container surface position below the cap 4 and is rotated. The step portion 5 of the bottle container 1 may be covered so as to be broken. The specific length and material of the cap seal 7 are not limited at all.

Further, the cap 4 according to the present invention is required to be a so-called screw cap that is attached and detached by a rotating operation, but its specific configuration is not limited. Similarly, the bottle container made of synthetic resin is naturally applicable regardless of the specific type and configuration of the bottle container.

Besides, in the present invention, all the specific configurations of the respective parts can be arbitrarily modified within the scope intended by the present invention.

(Effects of the Invention) As described above, the cap of the bottle container is provided on the outer peripheral surface below the mounting position of the cap of the bottle container. The tubular cap seal of the present invention, which is fitted by means of one or more strips, is provided on the peripheral surface portion covering the step portion at the time of rotation of the cap seal, in addition to the cutting guide line for cutting, which is cut in the longitudinal direction. Since a plurality of perforation lines that are engraved in the vertical direction and that are hooked and broken at the stepped portion are provided at appropriate intervals, use the above-mentioned cutting guide line for normal opening of the cap seal. The cap seal may be divided into pieces, for example, even if the cap seal is gradually rotated in order to improperly insert it into the container, the multiple perforation lines and the cutting guide line provided to cover the stepped portion. Either of them will be caught in the stepped part, and will be caught and broken. Can be appropriately prevented.

At this time, if only the cutting guide line is provided, it does not make sense to prevent the plug from being opened unless the guide line is positioned in the vicinity of the step, but this positioning is extremely difficult in terms of fitting work. Is.

However, in the case of the cap seal of the present invention, since a plurality of perforation lines are provided in addition to the cutting guide line, even if the heat shrinkage is not completely adhered and is somewhat loose, Even if the cutting guide line is located on the step, at least one of the perforation lines or the cutting guide line can be reliably broken by the step.

As a result, in the present invention, the trace of improper injection of a drug or the like into the bottle container can be reliably and easily determined by the presence or absence of breakage of the perforation line of the cap seal or the cutting guide line, and damage due to drug injection or the like is suitable. It has a special effect that it can be prevented.
