Anti-illegal opening and easy to identify container after opening

The invention relates to an anti-opening identification container; in particular to an innovative structural designer capable of preventing illegal opening and being easily recognized after being opened.

According to various plastic containers produced by vacuum forming, such as boxes, cups, bowls, etc., in the market, it is very suitable for use as ready-to-eat food (for example: cooked food or pre-shaved fruit) Fresh container. The advantages of this type of container are nothing more than recyclable and transparent material design. Therefore, consumers can clearly see the food in the container when purchasing, which can effectively avoid consumer disputes. Of course, the visual effects provided by the transparent container also have the effect of stimulating consumption. However, there are many kinds of foods. For liquid or liquid foods, such as: jelly, pudding, cheese, etc., the products are shipped to the store, and even to the consumer's home. They need to be transported or carried in order to ensure the process. The food inside the container does not leak out and the container must be sealed.

Conventional plastic containers generally have a box body and a cover body, and the two can be designed in a separate manner. However, no matter what method is adopted, the cover body can be closed when the exhibition is sold. In order to achieve the purpose of preservation, the two are usually designed with a concave and convex locking mode, which not only facilitates packaging but also has the advantages of re-opening and closing to prevent leakage.

However, such containers are usually used to hold ready-to-eat foods in stores. In addition to fear of theft, such foods are more worried about the loss of freshness after being unpacked, leading to deterioration of food, and even worse, such as thousands of people. The box body and the cover body of the conventional plastic container are only snapped and positioned with a simple concave-convex structure, and cannot be confirmed or recognized, and the product (food) is affected by the mischievous unsealing effect during the exhibition and sale. Even stealing, and if it is a malicious poison, the consequences are even more unimaginable.

Therefore, in view of the problems and unsatisfactory aspects of the above-mentioned conventional container structure, how to develop a container innovation structure that is more ideal and practical, and the users are looking forward to it, and the relevant industry must strive to develop breakthrough targets. And direction.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.

The main object of the present invention is to provide a container structure, and the technical problem to be solved is to think about an innovative breakthrough in how to develop a new type of container with anti-illegal opening which is more ideal and practical.

Another main object of the present invention is to provide a container that can be easily identified after being opened, so as to prevent the consumer from accidentally buying the unpacked packaged goods at the store.

The technical feature of the present invention is mainly to prevent the container from being opened and opened after being opened, and includes a receiving structure having a closed end and an open end, and an end edge of the open end of the receiving structure is outwardly extended. a ring-shaped lip; and a cover body for selectively closing the accommodating structure in a watertight manner; the bottom surface of the cover body is provided with an annular rib, and the outer edge of the annular rib top is provided with a cover to the outer ring The outer diameter of the cover is smaller than the outer diameter of the lip; when the cover is closed in a watertight manner, the annular rib is watertightly clamped to the inner wall of the open end of the receiving structure, and The cover plate is closely attached to the lip portion; a pulling portion extending from the periphery of the cover plate, the pre-break line is provided with a pre-break line, and the pre-break line is provided with a breaking portion, and The bottom surface of the breaking portion is convexly provided with a stopping portion; when the breaking portion is broken by the external force and is broken from the pulling portion along the pre-breaking line, the pulling portion forms a structure similar to a pull ring, which is convenient for the user to In the subsequent use process, the cover body can be easily removed from the accommodating structure through the holding portion. .

The main effects and advantages of the present invention are that the cover plate that is in close contact with the lip portion and the protruding portion that is protruded from the grip portion can be used to improve the difficulty of opening the cover body, thereby reducing the rate of theft and improving the item. The effect of theft. Moreover, after the packaged article of the present invention is subjected to irreversible damage upon unpacking, the clerk can promptly recover the problematic product, ensure the subsequent consumer's shopping rights and enhance the goodwill. Therefore, the innovative unique structural form and technical features of the present invention make the present invention a novel and progressive structural design in comparison with the conventional structure proposed in the prior art. Another function of the present invention is that the identification structure of the pre-breaking line is not designed in the annular rib of the cover body, and the main reason is that after the consumer unpacks and cannot be eaten once and covers the cover body, It can keep the function of water sealing.

Please refer to Figures 1, 2, 3, 4, 5, and 6 for a preferred embodiment of the present invention, but the embodiments are for illustrative purposes only and are not limited by the structure in the patent application; The container that is illegally opened and easily recognized after opening includes a receiving structure 10 and a cover 20 that selectively closes the receiving structure 10 in a watertight manner. In the preferred embodiment of the present invention, the accommodating structure 10 is a cup-shaped structure.

The accommodating structure 10 includes a closed end and an open end which are axially opposite to each other, wherein the open end is a flat structural surface, so that the accommodating structure 10 is erected with the open end upward. The inner edge of the open end of the accommodating structure 10 is formed with a ring recess 11 outwardly, and the end edge of the open end is outwardly provided with a ring-shaped lip portion 12. In the preferred embodiment of the present invention, the lip The opening end edge of the portion 12 of the accommodating structure 10 extends horizontally outward.

The bottom surface of the cover body 20 is provided with an annular rib 21, and the outer edge of the top edge of the annular rib 21 is provided with a cover plate 22, and the outer diameter of the cover plate 22 is smaller than the outer diameter of the lip portion 12. And the width of the extension is smaller than the width of the average fingertip. As shown in FIG. 4, when the cover body 20 closes the accommodating structure 10 in a watertight manner, the annular rib 21 is partially clamped in the annular recess 11 of the accommodating structure 10 in a watertight manner, and the cover 22 is It is closely attached to the lip portion 12. a pulling portion 23 extending from the periphery of the cover plate 22, the ring portion 24 is provided with an annular pre-break line 24, and the pre-break line 24 is surrounded by a breaking portion 25, the breaking portion 25 The bottom surface is convexly provided with a stopping portion 26, wherein the breaking portion 25 partially covers the lip portion 12 of the accommodating structure 10, and the stopping portion 26 is disposed close to the outer edge of the lip portion 12 of the accommodating structure 10. And the distance from the end of the blocking portion 26 to the end of the holding portion 23 is smaller than the width of the fingertip of a general person. When the breaking portion 25 is broken by the external force and is broken from the holding portion 23 along the pre-breaking line 24, the pulling portion 23 forms a structure similar to a pull ring, which is convenient for the user to pass through the pulling portion during subsequent use. 23 The cover 20 is easily detached from the housing 10 . A convex portion 27 is disposed at a center of the top surface of the cover body 20, and the convex portion 27 is provided with a recess 28 corresponding to the pulling portion 23 in a radial direction.

With the above structural composition design, the function (advanced) of the present invention for preventing illegal opening and easy identification after opening is described below by taking the storage of the food in the store as an example. The operation of the present invention is described as follows: as shown in Figures 3, 4, 5, and 6, when the food is contained in the accommodating structure 10, and the cover 20 is closed in a watertight manner, the accommodating structure 10 is closed. The annular rib 21 is snap-fitted in the annular recess 11 of the accommodating structure 10 in a watertight manner, and the cover 22 is closely attached to the lip 12. When a person with a bad heart wants to open the store in an illegal manner, similar to the present invention, the method is nothing more than a nail cover 22, with the thumb and forefinger pinch the cover 22 or with the thumb and index finger to pull the pull portion 23; However, the three methods cannot smoothly open the cover 20 which is watertightly combined with the accommodating structure 10, and the reasons are as follows:

Referring to FIG. 7, when the user wants to pick up the cover 22 with his nail, since the outer diameter of the cover 22 is smaller than the outer diameter of the lip 12, and the horizontal extension distance is rather limited; therefore, even if it is Lifting the cover 22 only partially deforms the cover 22 upward, and when the cover 22 is deformed upward, the nail of the illegal opener momentarily slips off the cover 22, and the cover 22 is itself The restoring force returns to the original state of the flat lip 12 at the first time, so that the bad heart loses. As shown in FIG. 8 , when the person with a bad heart gently pushes the cover 22 with his thumb and forefinger and wants to open the cover 20 of the present invention, since the cover 22 extends the width is small and close to the accommodation. The lip 12 of the structure 10, together with the blocking effect of the side wall of the raised portion 27 above the cover 20; therefore, it is almost impossible to pinch the cover 22 with two fingers, so if the cover 20 is to be opened in this way, it is almost impossible to find The cover 20 cannot be opened smoothly without a proper point of application. Further, as shown in FIG. 9, when the person with a bad heart wants to illegally open the present invention by the holding portion 23, since the breaking portion 25 is provided with a convex stopper portion 26, and the stopper portion 26 to the holding portion 23 The distance between the end edges is smaller than the width of the fingertips of the general person; therefore, the fingertips of the person who wants to open the cover 20 illegally will abut against the stoppers 26, and the fingers cannot be pinched up and down, and of course, the cover cannot be smoothly opened. 20. Therefore, the unsatisfactory person can hardly open the cover body 20 of the present invention without destroying the pre-break line 24, and the action is inevitably exaggerated and bizarre due to inconvenient force, which can not only delay the time but also promptly find out for the store personnel. By drinking, the food (item) contained in the present invention is reduced.

In the above, the control of the present invention is illegally opened by the hand, and when the person with a bad cause wants to use the small tool to pick up the cover 20 under the grip portion 23, as described above, the stop portion 26 is along the accommodating structure. 10 The outer edge of the lip 12 is disposed close to it, and unless the tool has a flexible structure, it cannot extend below the cover 22, and of course, the cover 20 cannot be picked up; further, it is surrounded by the pre-break line 24. The breaking portion 25 partially covers the lip portion 12 of the accommodating structure 10. Therefore, when the gadget is illegally extended to the cover plate 22, the pre-breaking line 24 above the lip portion 12 is inevitably broken first, and the small size cannot be successfully obtained.

When the consumer wants to open the cover 20 and take out the article after the checkout, the finger is first pressed against the broken portion 25 to break the pre-break line 24, so that the breaking portion 25 is separated from the pulling portion 23, and the pulling portion is pulled. 23, forming a structure similar to the pull ring and then matching the groove 28 on the cover body 20, the consumer can easily pull the cover body 20 by the pulling portion 23 to open the receiving structure 10 to take the object. Since the invention can be irreversibly damaged as soon as the pre-break line 24 is opened after the article is packaged, the clerk can always pay attention to whether the pre-break line 24 on the cover 20 is damaged when the patrol shop is inspected. It can instantly judge whether the package has been unpacked, and can timely recover and keep the freshness of the ingredients in the container, and avoid the defective or problematic goods entering the hands of consumers, thereby achieving the purpose of ensuring goodwill.

Further, as shown in Fig. 12, a top view of another embodiment of the present invention is identical in structure and theft prevention to the first embodiment, and only has a shape which is changed from a circular shape to a rectangular-like structure.

Advantages of the Invention: The invention discloses a "container that is easy to identify after being opened illegally and opened", and the invention is mainly controlled by the innovative unique structure and technical features of the receiving structure and the cover body. The prior art] has the following unpredictable effects: 1. The cover plate extended by the cover body is closely attached to the lip, and the width of the extension is less than the width of the fingertip of a typical person. It is impossible to pick up the cover with your fingertips, and of course the purpose of illegally opening the cover cannot be achieved. 2. The cover body of the present invention is provided with a convex portion. Therefore, when the two fingers are used to pinch the cover plate to achieve the purpose of illegal opening, the operator's finger may not lift the cover plate due to the blockage of the convex side wall. It is also impossible to achieve the purpose of illegally opening the cover. 3. The bottom surface of the breaking portion of the present invention is convexly provided with a stopping portion, and the distance from the stopping portion to the end edge of the pulling portion is smaller than the width of the fingertip of the ordinary person, so the two fingers are used to pinch the edge of the pulling portion. When the purpose of illegal opening is achieved, the operator's finger will not easily apply force due to the restriction of the stopper, and the distance between the stopper and the end edge of the holding portion is smaller than the fingertip width, and the fingertip is relatively easy to slide open. The holding part is also unable to achieve the purpose of illegally opening the cover. 4. The blocking portion of the present invention is disposed close to the outer edge of the lip of the accommodating structure, so that the cover cannot be illegally opened by the small tool; further, since the broken portion is partially covered on the lip of the accommodating structure, Therefore, when the tool is illegally extended to the cover, it will inevitably destroy the pre-break line above the lip, and the small one will not succeed.

The above embodiments are intended to be illustrative of the present invention, and are not to be construed as limiting the scope of the invention. The principles are changed and modified to achieve an equivalent purpose, and such changes and modifications are to be included in the scope defined by the scope of the patent application as described later.
