Description

[Detailed description of the invention] Technical Field and Background of the Invention of a Closure Capable of Detecting Freshness and Abnormal Opening The present invention can detect the freshness of beverages, etc. in a container and detect abnormal opening such as tampering. It concerns obturators.

The technical field to which the present invention pertains is that of closures for bottles, jars and other containers; Do not maintain a full or partial vacuum inside the container until you remove the closure, such as the cap, from the container. In the field of closures such as caps for containers that are kept under vacuum be. However, this field is not limited to vacuum-filled containers; Containers that can maintain a partial vacuum after sealing without first filling the contents under vacuum conditions , and also includes order beverage filling containers in which the contents are filled under pressure.

The contents of unopened containers are important for food and drink consumers, as well as from a hygiene perspective. Detection of product freshness and abnormal tampering of containers is very important in the filling industry. be. To detect the vacuum condition inside a sealed container and the presence or absence of spoilage or deterioration of the contents. Commonly used means check the cover with a concave area in the form of a key tongue It is to be. Vacuum leaks when gas is generated due to the action of harmful bacteria. If KFi, the above-mentioned concave area expands outward 11, so that f'LK Therefore, deterioration of the contents can be easily detected.

In the case of containers such as cans, there should be no sound of air entering when the can is opened for the first time. If the can's seal is filled, or if the contents do not come out when the can is opened, It is thought that gas was generated due to the action of harmful bacteria or the presence of harmful bacteria. It will be done.

Small closures such as container closures and special K [caps] can be easily detected for abnormal opening. I don't know. Such closures may include a Various means such as shrink-tight plastic wrappers may be placed on the outside of the closure to However, these means are not abnormal tamper detection means. plastic Although bottles, jars and other containers are currently used.

A method has been developed to easily detect the freshness of the contents and whether or not the package has been tampered with. It wasn't. In detustic bottles and jars, wIK indicates mold separation at the bottom of the bottle or jar. If you make a hole with a laser beam aW4 or a hypodermic needle along the line, it will break and prevent unauthorized opening. It can be easily sealed.

Is it easy to break the seal of the container, reduce the freshness of the contents, or open the container abnormally? There is a strong desire to develop a closure device such as a cap that can be detected reliably. However, Therefore, the present inventor has developed a new closure device as described below.

structure of invention The basic idea of the invention is embodied in a substantially cylindrical closure such as a cap. According to the present invention, the peripheral groove is provided with a groove (referred to as a peripheral groove). Cone-shaped surfaces of substantially equal dimensions and opposite each other in the solution state? It is composed of

When the closure is installed to seal the container, the closure is compressed to open each of the aforementioned circles. The conical portion is bent to form a substantially toroidal groove within the periphery of the cylindrical side wall. make it happen The pressure of the obturator is similar to that of a compression spring in the distorted conical part. In this way, potential energy can be stored. Vacuum, partial vacuum or potential vacuum within the container During this period, outside air pressure is applied to the container and the closure is maintained in a compressed state. this pressure The contraction condition continues until the seal is broken, at which point the closure device immediately This will return to the loose form 11 and expand, creating two opposing conical parts. This allows the destruction of the sealed state iI to be detected.

In another embodiment of the invention, the nine opposing conical portions of the obturator have a cylindrical shape 11! An outwardly protruding peripheral edge is formed on one portion of the tube. ! When in the l-solution state, the above-mentioned opposing The bottom portion is substantially conical. The closure is compressed and the container is sealed. When the external protrusion is installed, the outward projection substantially trots around the cylindrical portion of the obturator. Exists in the form of an id-like ring. The seal of the container is broken or harmful bacteria If gas is generated due to the action of A, the obturator will expand and the observer will notice that Situations can be easily detected. The above description describes the use of conical sections of equal size. However, it may be used by arranging the surface of another rotating body in a quaternary manner. , it is also possible to use a surface other than the surface of a rotating body.

The first example uses opposing conical surfaces of unequal dimensions to Sometimes it causes a partial latch to form. Ru. In this case, the conical surface is compressed to deflect and latch. The border A certain small pressure difference is necessary to keep the conical surface ■ sufficiently The method of overcentering and latching (cvpm) was developed by the applicant, S. Patent No. 32379 (reissue) K is disclosed. Freshness and freshness according to the IC of the present invention A folded ring portion defining a conical surface is used as a means of detecting abnormal diastasis. d rims) The hinge operation is based on a predetermined slight difference in surface pressure. At times, a mechanism similar to that of a spring can produce a sufficient amount of potential for a given purpose. potential energy (i.e. for removal of the rear latch and release of the detector) It can store the required amount of energy.

Generally, one closure such as a cap is placed in substantially the same direction above and below the detector. It has a side wall portion of a diameter. The walls are generally cylindrical or oval in shape, but these shapes It is not determined solely by

11! In the third specific example, the diameter of the upper omw part O is different from the diameter of the lower flit part. and one of these is assembled in the obturator with a modified folded ring section. Together, they form a sensing device. The potential energy is the above modified folded ring part. stored inside.

The fourth example Fi is particularly a cap bottle of a pressurized container filled with nine contents. Regarding the sensing device, the various specific examples described above also apply. of pressurized contents Can be used for detection. When in a non-contracted state, that is, in a remitted state, this detection device is defined by a smaller folded ring section and a larger folded ring section. It has the shape of a double cone (deubl・tel・) and is placed substantially within the container. . Larger upper fold ring section.

7 runs surrounding the upper cone/) B is narrow. This 7 lunge is a filling jar (c attaching jar) (as in case of D closure O, a threaded scarf It is fixed to the container via a flat ring with a flat part to seal it. Addition like carbonated water When filled with compressed contents, the bicone arches upward and forms a toroid. The shape of the bicone holds the potential energy of the detector, and the bicone is attached to the top of the container. It exists and can be seen from the outside with the naked eye.

In yet another embodiment, the conical section, the one-part wall section, and the O-junction are modified. KoO The R modification was made to further widen the angle of deflection of the joint, and this is why the K.

Use of various Class 021 Of lath materials and elastic materials as materials of construction for closures becomes possible. The above changes in the closed AK do not apply to the US patent application filed by the applicant. Application No. 119/Mu52 is described in the specification.

It is held in a compressed position by being released when the pressure difference disappears.

That is, the pressure of the surrounding air keeps the obturator in a compressed state 11. The seal is broken The container is airtight! If J is lost, or if there is harmful F in the container. If this occurs, the pressure inside the container will rise to a level equal to or lower than that of the outside air. will be high, thus closing due to air intrusion or generation of The device expands to the relaxed state dimensions shown in FIG. Sufficient pressure is created inside the container. In this case, the obturator can never expand to its dimensions when in remission. In some cases, opening of the container or generation of gas within the container may result in expansion of the closure (i.e., It can be immediately identified with the naked eye by its size (when it is in a state of expansion). .

This compressed state is due to the vacuum or partial vacuum in the container (//co) as mentioned above. It is maintained by the pressure of the surrounding atmosphere on the obturator. when the container is opened or gas is generated in the container, fiK is the internal pressure equal to the external pressure 9 or more. The high pressure above is reached and the obturator is inflated until it reaches the state shown in Figure 3, i.e., the state of relaxation. do. Expansion of this closure immediately detects alteration or activation of the contents within the container. I can know.

The obturator is capable of chevron deflection at the inner and outer folded ring sections. It can be formed using a material such as, in particular, a zotastic material. Especially Figures 1 and 2. In the closure shown in the figure, in the outer folded ring sections (30) and (3,2) The deflection of the chevron is quite large, while the inner folded ring part (two points) K The deflection is relatively small; likewise, in the embodiments shown in FIGS. The deflection at the ring-shaped joint (/30) and (/3) is caused by the bending at the outer ring part (l F) The folding ring shown in the attached drawing has a much larger deflection! ! (kot) and (lat) are simple shapes, but simple folding rings Use a substantially cylindrical band to replace the section and place it over each pair of conical sections. It is also possible to match the upper and lower folded ring parts Kwr. In this case , the deflection in each folded ring section is substantially reduced by the cylindrical band However, each conical section is free to flex in any direction. There is only one closure device. It is made from a material such as Iridero♂ren, which is described in the above-mentioned patent specifications related to RK. is advantageous. However, it is necessary to use materials with greater rigidity. In the case of ) regarding an improved ring structure for power distribution in the patent specifications of the present applicant. Improvements can also be made according to the teachings provided.

Figures 3 and 6 show that the degree of chevron deflection experienced by the closure material is reduced. 3 is a drawing showing a specific example of changes in the aspect that can be made to the folded ring portion in order to

In the specific example shown in FIGS. 51C and 5B, the i-wall (K/A) is The conical surface (K) is integrally joined via the ring part (K 30). Occasionally The overlapping ring WA (ko30) is based on the patent specification of the applicant's 811IM. formed in the same way as described, i.e. the ring is (ko30) k close The bent parts (2 pieces 9 and C231") are made of a membrane, and these bent parts also bend. Therefore, the degree of bending of the chevron of the folded ring part (30) is reduced. Do a little.

If such a proximal bend is formed, a rigid material such as light metal may be used to secure the closure. can be manufactured.

By the same method, the detection side wall portion (3/4) protruding outward is shown in Fig. Aa. It can be formed as shown in Figure Ab, i.e. with a folded ring part (330") inside. It is made in a protruding shape, and the proximal bent part (3 pieces) and (,7, 7/), the degree of deflection of the folding ring ff1 (, 7, 70) can be reduced. can be reduced to its lowest value. The material of construction of the obturator, as well as the obturator wall O thickness and From the data regarding the selection of the overall diameter of the obturator, the embodiment shown in Figure 6 of Figure 3 of the irises was determined. The very overlap that could determine whether a closure needs to be manufactured The cone-shaped part in the flexed state receives sufficient mechanical energy over a long period of time. It is important to use materials that can be maintained. Has high creep resistance, Materials that are less likely to dissipate the applied mechanical energy are highly preferred. Shape when pressed Materials that loosen while being kept for a long period of time are not preferred.

However, as a function of time, the material such that the cre-ft-predicted J)K yields , can be used as a detection means to detect excessively long storage times. .

In the case of a closure device where creep can be predicted in this way.

Excessive length should not expand to its relaxed state dimensions when removed from the container. The storage time is immediately detectable, i.e. the closure remains sealed until it is intentionally removed. 4. If the condition is well maintained, excessively long storage due to creep may occur. Time can be detected, in other words, it can be detected that the contents have become stale.

In this specification, this E! Detection equipment that can detect freshness and abnormal opening related to AK As an example, the improved functionality of the closure attached to the top of the at-take jar. Although it is explained in detail,! Side walls of wooden or light metal containers Additionally, the aforementioned peripheral groove or protrusion can also be integrally formed. When the container is full When filled and sealed, the freshness and tamper detection device A round obturator is used herein which operates in a manner similar to that of the obturators previously described. Although it is described in detail, it should be installed on a curved oiui part. Obturators in oval and other shapes can also be made from the same piece of metal.

The angle of the tip of OeA near the wall is 1lIj for both! at a substantial distance from the The groove angle at the location is also substantially small.

When the obturator is compressed to the condition shown in Figure 1/Fig. Deflection, O/amount-centering is done. Already mentioned Toto (, U major groove C5-3 0) includes the part with a small groove angle, but due to the bending of this part, The recovery force is stored as a result of the pressure between the contents inside the container and the surrounding atmosphere. The Kw4 chain can be relaxed or expanded as soon as the force difference decreases. It is the power of size. In this variant, the cylindrical 9111 part 1/A) or C! /l ) serves as a skirt, i.e. this closure It is also useful as a backup.

The obturator shown in Figure 1 has a pair of conical side walls (6) and (6). These side wall portions are formed by an upper folding ring portion C430) and a lower folding ring portion C430), respectively. They are connected via overlapping rings (WACA3).
