Abstract

PROBLEM TO BE SOLVED: To provide an inexpensive tamper-proof cap in which the presence or absence of unsealing of a container using a cap with a small outer diameter can be easily recognized, the cap can be easily unsealed even by a child, an old person or the like with less power, any apparatus such as a heating furnace need not be prepared, the presence or absence of unsealing can be clarified by rapidly sealing a cap plug after filling the content in the container at a normal temperature, and the cap can be unsealed without any trouble.SOLUTION: The tamper-proof cap includes a small cap for closing a spouting port of a container body having a fitting and closing function on one end by the fitting and closing function and an over-cap covering the small cap. In the tamper-proof cap, the over-cap has a thin-walled brittle line and by cutting and breaking the thin-walled brittle line, the over-cap is detached to release the fitting and closing function of the small cap.

Description

  The present invention is a container lid made of synthetic resin, more specifically juice, milk, liquor, tea, soy milk, tempura oil, dressing, soy sauce, liquid seasoning and other liquids, sugar, starch, coffee powder, cinnamon powder, potato starch, Caps for containers used in containers that can contain powders such as sesame seeds, granules, etc., and whether or not the containers have been opened can be clearly identified and cannot be restored. It relates to a cap that can.

  It is necessary to be able to clearly discriminate whether or not the container has been opened in order to prevent consumers from ingesting something that contains malicious substances such as poisons, pathogens, and needles. Further, whether or not the package has been opened is considered necessary for confirmation of consumption within the expiration date of use of the contents.

  In order to make it possible to clearly determine the virginity of this container, as shown in Patent Document 1, a rupture line is provided below the cylindrical skirt portion of the cap, and a pilfer proof hem is provided below the rupture line. The flap piece, which is provided on the inner surface of the pill fur proof and the lower end of the flap is inclined upward, engages with the “chin lower edge” provided under the mouth of the container body, Since the upward movement in the axial direction of the outlet is prevented, the cap must be broken unless the ridges of the breaking line connecting the cap cylindrical skirt and the pilfer proof skirt are broken by the pulling force caused by the rotation of the cap. Is not lifted and does not open.

  For this reason, in this method, in order to open the cap, a force required to cut a plurality of protrusions at a time is required, and therefore, this method can be used only for a large cap. This is because if there are few ridges, it will be easily damaged during transportation and locking, making it impossible to confirm virginity.If there are many ridges, the outer diameter of the cap will be increased to increase the moment of rotation. There is a need to make it bigger. Therefore, it has been adopted only for a large-diameter container. In addition, the cap of this container has a problem that even if the outer diameter is increased, it is difficult for a person with weak force to open.

  In addition, it is necessary to keep the caliber of the container small, such as seasonings such as soy sauce and chili oil, etc. . Since such a container has a small diameter, it becomes a container using a cap with a small outer diameter, so even a container using a cap with a small outer diameter needs a container that can be easily understood whether or not it is opened. . In the case of Patent Document 1, the container is difficult to open unless it is a strong person. Even in the case of such a small diameter, it was necessary to make the container easy for a person with weak power to easily open.

  In contrast to such a technique, Patent Document 2 proposes a method in which the vicinity of the cap and the container mouth is covered with a shrink film so that it can be easily determined whether or not the container is opened. Although this method is easy, the cap and the container need to be close in thickness. Alternatively, it is necessary that the lower neck portion of the container is long and the cap and the lower collar portion of the neck are simultaneously covered with the shrink film. As a manufacturing method, first, a shrink film is formed into a cylindrical shape, and after the contents are filled in the container, the cylindrical shrink film is covered, and the container is passed through a heating furnace. For this reason, it cannot be adopted unless a heating furnace is installed in the filling factory. Even if there is a heating furnace, this method heats the container itself, so the container body shrinks, the capacity decreases, the contents overflow, the container swells, and the contents are heated. There was a risk of problems with scents flying, alteration or discoloration. In addition, shrink film requires processing such as fusing and cutting the film into a cylindrical shape and inserting weak lines such as perforations before entering the heating furnace. I had to be expensive.

  In addition, since the shrink film is a stretched film, even if a weak line such as a perforation is provided, a problem that the film is displaced and tears easily occurs. In addition, since it contracts and tightly adheres to the container, once the knob provided near the line of weakness slips and tears, it is difficult to grasp the opportunity to cut and tear it diagonally. For this reason, there has been a problem that it takes time and effort for consumers to open the package.

Japanese Patent No. 1202159 Japanese Patent Laid-Open No. 2003-20056

  Open in containers that use caps with a small outer diameter to put things that are not good enough, such as seasonings such as soy sauce and chili oil, or those that have high fluidity such as dressing. The presence or absence is easily understood. Moreover, it is a first object of the present invention to provide a tamper-proof cap that can be easily opened even by a weak person such as a child or an elderly person.

  Also, it is not necessary to prepare equipment such as a heating furnace, and after filling the contents into a container at normal room temperature, the cap should be immediately locked so that the presence or absence of opening can be clearly identified. It is a second object of the present invention to provide a tamper-proof cap that can be opened and supplied at low cost without requiring the effort of the consumer to open.

  In order to achieve the above object, a tamper-proof cap according to claim 1 of the present invention is a small cap that closes by a fitting and closing function with respect to a dispensing port of a container body provided with a fitting and closing function at one end. A tamper-proof cap comprising an overcap covering the small cap, wherein the overcap is provided with a thin fragile wire, and the thin cap fragile wire is cut and broken to remove the overcap, and the small cap is fitted. It is a tamper-proof cap characterized by being able to release the joint closure function.

  The tamper-proof cap according to claim 2 is a tamper-proof cap characterized in that the fitting and closing function is due to rotation of a screw.

  Furthermore, the tamper-proof cap according to claim 3 has a fitting part around the base of the container body for pouring, and the overcap is fitted into the fitting part of the container body, and the small cap is fitted and closed. It is a tamper-proof cap characterized by a mechanism that cannot be released.

  Next, in the falsification preventing cap according to claim 4, the fitting portion with the overcap provided around the base of the pouring port of the container body is a hook, and a fitting claw is provided at the lower end of the overcap. It is a tamper-proof cap.

  If the tamper-proof cap of the present invention is used, even a cap with a small diameter can be used without any problem, even a weak person can be opened without any problem, and it cannot be removed due to warping and cutting in the middle. , You can see if there is any opening. In addition, it can be produced without special equipment such as a heating furnace, can be opened easily, and does not fail. Therefore, it reduces the labor of the consumer when opening the tamper-proof cap. It is possible.

It is sectional drawing of the container mouth vicinity which inserted the tampering prevention cap of this invention. It is a perspective view of the tamper-proof cap of this invention, (2-1) showed the molded product and (2-2) showed the halfway state when removing a tamper-proof cap. FIG. 4 is a cross-sectional view of a state in which the knob of the tamper-proof cap of the present invention is caused to be removed. It is sectional drawing which cut and cut | disconnected the cutting strip | belt part of the tamper-proof cap of this invention. It is sectional drawing of the state which opened the tamper-proof cap of this invention, and the small cap appeared. It is sectional drawing of the state which removed the small cap of this invention.

  Hereinafter, the plug of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of prevention of tampering of a small cap according to the present invention. The spout 12 of the container body 1 to be used has an outer side, a screw part 13 on the tip side, and a hook-like fitting part 11 at the root. The thread portion at the tip is not necessarily a screw shape, and may be a fitting projection ring. Although the small cap 2 is shown as a cap having an internal screw 22, it may be a cap having a fitting protrusion. The small cap is required to be able to easily close and open the spout 12 of the container body. An outer cap 3 for preventing tampering is fitted to the outside of the small cap 2. The overcap 3 is fitted by a stoppering operation after simply fitting a small cap. Once fitted, the overcap cannot be removed unless it is broken. Further, the overcap 3 is adapted to be fitted into a hook-shaped fitting portion 11 at the base of the mouth of the container main body 1 so as to maintain the position.

  Because of this positional relationship, the small cap cannot be removed when the overcap is fitted. Therefore, in order to remove the small cap, the overcap must be destroyed. For this reason, since the container once fitted with the overcap cannot be opened as it is, the presence or absence of the opening can be clearly discriminated, and the cap cannot be restored and prevents tampering.

  FIG. 2 is a perspective view of the overcap. 2-1 indicates a state where the overcap is formed, and 2-2 indicates an intermediate stage when the overcap is removed. As formed, the knob 31 is tilted near the top of the cap. In order to remove the overcap, the overcap is broken and removed by raising the knob 31 and pulling it up, and using the thin fragile wire 35 to separate the cutting band 34. The thin-walled weak line 35 may be a thin-walled state, or a part of the hole may be continuous, or a specific part such as a cutting start part may be a hole. Provide as follows. However, it is ideal to provide the thin line of weakness 35 on the left and right sides of the cutting band 34 as shown in FIG. 2, but in the case of a soft material as a whole, it may be provided only on one of the left and right sides. In that case, the cutting band 34 cannot be completely separated from the overcap 3, but if the periphery can be completely cut even at one place, the entire overcap 3 is distorted by pulling the knob 31 and separated from the cap 2. Can do. Further, since this overcap is made by injection molding, the difference in thickness can be made sufficiently large, so that the cutting line can be surely cut along a straight line along the thin fragile line.

  The overcap is higher than the height of the small cap, and the small cap 2 cannot be removed when the overcap is present. The overcap knob 31 is provided with a hole and a finger inserted to make it easy to lift, but of course, the hole may not be provided, but it may be recessed, or a surface that is not slippery due to linear irregularities or wrinkles. May be.

  On the inside of the overcap, a fitting claw 33 that fits with the bowl-shaped fitting portion 11 of the container body 1 is provided. If it is partial, two or more, preferably three or more are provided. It is also possible to make a ring shape and fit the whole circumference.

  The lower position from the inner fitting claw 33, which is the length of the lower side of the overcap, extends to the vicinity of the shoulder height of the container body. By doing so, the overcap does not wobble so much and the adjustment when inserting the stopper can be easily performed.

  The material of the overcap is olefin resin such as polypropylene, polyethylene, polymethylpentene, etc., non-acrylic / butadiene / styrene resin (ABS resin), acrylonitrile / styrene resin (AS resin), high impact styrene resin, etc. Crystalline resins can also be used.

  FIG. 3 is a cross-sectional view showing that the cutting band 34 is started to be pulled up while raising the overcap knob 31 and cutting the thin fragile line 35. A thin hinge part 32 is made at the base of the knob 31 of the overcap 3, but this part is simply pulled out of the knob 31 to make it easier to grasp. You can reinforce it with meat or ribs. This shape is a portion to be changed and adjusted according to the shape of the small cap 2 and the material of the overcap 3.

  FIG. 4 shows a state in which the thin fragile line 35 of the overcap 3 is pulled up and the cut band 34 is removed from the overcap 3. At this stage, since the overcap 3 has lost a part of the outer periphery, it can be easily detached from the small cap 2 by widening the portion where the cutting band 34 was present.

  FIG. 5 shows a state in which the portion where the cutting band 34 of the overcap 3 was widened and completely removed from the small cap, and the small cap is merely fitted to the container body 1 with only a screw. As shown in FIG. 6, the contents can be taken out by simply removing the small cap 2. The fitting of the small cap 2 and the container main body 1 can be performed not only by a screw method but also by a stopper-type fitting. It is necessary for the small cap to be provided with a mechanism for completely stopping the liquid and powder, such as the inner ring 21 and the contact ring 23, as in the normal cap.

  Although the present invention is a cap as described above, it is preferable that the presence or absence of the small cap 2 is easily determined from a gap around the knob 31 of the overcap 3 or a hole provided in the center. This can be confirmed when the small cap is accidentally forgotten. Moreover, the presence or absence of opening can also be confirmed visually.

  In order to use the tamper-proof cap of the present invention, the container body is filled with the contents, the small cap is closed, and then the overcap is simply plugged. Therefore, it is possible even at room temperature, and the container, cap, and contents are not deteriorated by heating. Further, there is no need for a heating furnace for shrink film. Basically, the overcap is inserted from above and pressure and impact are applied so that it drops down to the shoulder of the container, but it is possible to use a hand press or just a plastic hammer. Actually, it is efficient to plug the air cylinder so that it is pushed into a certain position.

Even if the tamper-proof cap of the present invention is a cap having a small diameter, it does not require much force for opening, so even a person with weak power can open the cap. In addition, the cap is inexpensive because it can be manufactured by simple injection molding. In addition, no special heating furnace is required. It can be easily assembled at room temperature and can be inserted only with pressure. In addition, since the small cap cannot be removed unless the overcap is destroyed, the effect can be easily obtained, such as prevention of tampering at low cost.
