Description

Container with anti-illegal opening identification function

The present invention relates to a container; in particular, it refers to the disclosure of an innovative structural form of a container with the function of preventing illegal opening and identification.

Press, by vacuum forming various thin-shell plastic containers (hereinafter referred to as containers) such as boxes, cups, bowls and other shapes in the store, it is very suitable for ready-to-eat food (such as cooked food or cut In addition to the advantages of low manufacturing cost and recyclability, the advantages of this type of container include transparent design, so consumers can see the food in the container at a glance when purchasing.

Conventional containers generally have a box body and a cover body, and the two can be connected on one side or separated. The cover body can close the box body to achieve the purpose of keeping fresh, and the two are usually designed in a snap-type design with a concave-convex fit, which is not only convenient for packaging, but also has the advantage of being able to be opened and closed repeatedly.

In view of the problems such as the simple buckle type between the box body and the cover body of the conventional container, it is still easy to be maliciously unpacked in the store and difficult to identify afterward. Therefore, the industry tends to take various contingency measures. Use staples to nail the snap edge between the box body and the cover body, and then unpack it after the consumer buys it back. However, this method often results in the fact that most consumers forcefully open the box body junction with lid The structure is broken and damaged by staples, resulting in the defect that the container can no longer be used repeatedly.

Another industry has developed a method that only allows consumers to pull apart a set snap portion between the box body and the lid of the container and the pull tab, and once the pull tab is pulled apart, the snap portion will The design of an annular tear line around it is disconnected and left in a card slot, so as to be used for identification by store managers and checkout personnel; although this conventional structure has subsequent sustainable repeatable switches Use, it will not destroy the advantages of other structures of the container, but it is still found in the use experience that because most of these containers are designed with transparent, even if the aforementioned holding piece is pulled apart, the elastic force of the plastic material will restore it to its original shape. Therefore, if a malicious unpacker covers the lid back to its original position, the pull tab can also return to its original position and flat state. In addition, the transparency of the container makes it difficult for store managers and checkout personnel to easily identify them. Whether the buckle part has been opened, there are still problems and disadvantages that the anti-illegal opening identification effect is not ideal.

On the other hand, when the conventional pulling piece performs the pulling action, because the connecting ribs of the annular tear line are usually designed to be evenly spaced and distributed, the resistances faced by the pulling piece during the pulling apart process are usually at intervals. Relatively average state, so if the pulling piece is tilted due to the resistance of the connecting rib, it will often show a state of smooth curvature. However, this state is relatively insignificant for the visual recognition of the opening. It is a breakthrough to be further improved.

In addition, in the process of pulling the holding pieces apart, the resistance is often too large because the equally spaced connecting ribs are too far away from the center point of the circle formed by the annular tear line. Insufficient strength, but it is pulled and torn and damaged, which will cause difficulty and inconvenience in the opening process of the container product.

Therefore, in view of the problems existing in the conventional container technology with anti-illegal opening and identification function, how to develop an innovative structure that can be more ideal and practical remains to be considered by the relevant industry for breakthrough goals and directions; In view of this, The inventor has been engaged in the manufacture, development and design of related products for many years, aiming at the above-mentioned goals, after detailed design and careful evaluation, he finally obtained a practical invention.

The container includes the following: a box body 10 including an opening 11 and a first abutting edge 12 arranged around the opening 11 ; a cover body 20 selectively covering the opening of the box body 10 11, the cover body 20 is provided with a second abutment edge 22 on the peripheral side for abutting against the first abutment edge 12 of the box body 10; The two abutting edges 22 are outwardly convex, the holding piece 30 includes an outer end edge 31 and two side edges 32 ; The convex portion 41 , a buckle groove 42 provided at one place of the box body 10 for the alignment and positioning of the buckle convex portion 41 , and an annular tear line 43 provided on the periphery of the buckle convex portion 41 constitute a When the holding piece 30 is pulled, the ring tear line 43 is broken and the snap protrusion 41 is retained in the snap groove 42. The ring tear line 43 includes a spacer ring A plurality of connecting ribs 431 in a row and a plurality of holes 432 formed between adjacent connecting ribs 431 in a hollow shape; The peripheral areas of the grooves 42 are in a planar abutting contact state. In the planar abutting contact state, the holding piece 30 protrudes out of the first abutting edge 12 of the box body 10 for a pulling operation. The annular tear line 43 corresponds to the inside of the first abutment edge 12 of the box body 10 ; and is defined by the center point of the outer edge 31 of the holding sheet 30 extending through the center point of the annular tear line 43 A longitudinal line L1 is drawn, and a transverse line L2 is defined in the center of the annular tear line 43. The transverse line L2 and the longitudinal line L1 are in an orthogonal relationship with each other; The sheet 30 is structurally and is a plane type with flexible properties, wherein the annular tear line 43 is annularly arranged at a space around the periphery of the buckle convex portion 41, so that the strength weakening portion of the holding sheet is Formed by the annular tear line 43 to the narrow area existing between the side edge 32 of the holding piece 30 , the strength weakening portion 50 of the holding piece is used to make the holding piece 30 stretched. A bent portion is formed, so that the holding piece 30 is inclined upward and easy to identify after being pulled; a tear line strength weakening unit at least includes two first weakening slits 432a, the two first weakening slits 432a The two sides of the annular tear line 43 adjacent to the two sides 32 of the holding sheet 30 are symmetrically arranged with each other, and the extension length of each of the first weakened slits 432a is between the positive and negative of the transverse line L2 as the center point. Between 15 and 20 degrees (θ1); and the annular tear line 43 is defined by one side adjacent to the outer end edge 31 of the holding piece 30 and one side adjacent to the second abutting edge 22 of the cover 20 Two normal strength tear line segments 61 and 62 are formed, and the two normal strength tear line segments 61 and 62 are spaced apart by the arrangement of the two first weakened slits 432a.

With the above-mentioned structural composition and technical characteristics, the container with the anti-illegal opening and identification function disclosed in the present invention, as shown in FIG. 5 in practical application, can mainly utilize the difference spacing of the weakened gaps of the tear line strength weakening unit. The shape setting feature enables the strength weakened portion 50 of the holding piece 30 to be in a warped state with different curvatures from other parts of the holding piece 30. That is, when the holding piece 30 is pulled up, please refer to FIG. 6 As shown in the state of change in FIG. 7 , when facing the connecting rib 431 and the slot 432 with general spacing, the holding piece 30 will be deformed upward to a certain extent due to the resistance of the connecting rib 431 . However, when the section corresponding to the first weakened slit 432a is reached, the aforementioned resistance resistance is instantly lost, causing this section of the holding piece 30 to have different curvature states, and then when the holding piece 30 is pulled When it is continuously pulled up and crosses the first weakened slit 432a, it will face the connecting rib 431 and the slit 432 with a general spacing again. Therefore, when the holding piece 30 is completely pulled up, as shown in FIG. A weakening of the front and rear ends of the slit 432a makes the holding piece 30 not appear to be in a state where the holding piece 30 is tilted smoothly in a single arc, so that the human eye can more easily recognize that the holding piece 30 is pulled apart and tilted from the outside. On the other hand, when the pulling piece 30 is pulled up, the strength weakening unit is characterized by the shape of the tear line, so that the connecting rib will not Too far away from the longitudinal line L1 can effectively avoid Due to the excessive resistance of the connecting rib of the annular tear line, the problem of cracking of the pulling piece 30 occurs, so as to effectively avoid the problem of inaccurate operation of the pulling piece; The section of the first weakened slit 432a formed on both sides of the annular tear line 43 is usually provided with 2 to 4 connecting ribs in the conventional structure. It has the largest relative resistance to the pulling force of the holding piece 30, and is the least likely to be pulled off, because the distribution angle of the connecting rib here, in addition to the reason that the connecting rib is far away from the tension part and is not easy to transmit the pulling force, the connecting rib there will be Similar to the twisting method to face the tensile force, and the plastic elastic and toughness is less likely to be twisted and broken, so it is most likely to generate resistance and cause the problem of cracking of the pulling piece 30, and this is the present invention. One of the reasons for solving the conventional problem is to weaken the technical features of the slit 432a.

As shown in FIG. 5 , in this example, the tear line strength weakening unit further includes a second weakening slit 432 b , and the second weakening slit 432 b is formed on the annular tear line 43 near the outer end edge 31 of the holding piece 30 . On one side, the extension length of the second weakening slit 432b is within an angular range (θ2) of plus or minus 15 to 20 degrees with the longitudinal line L1 as the center point.

As shown in FIG. 5 , in this example, the tear line strength weakening unit further includes a third weakening slit 432c, and the third weakening slit 432c is formed at the outer end edge of the annular tear line 43 away from the holding piece 30 On one side of 31 , the extension length of the third weakening slit 432c is within an angular range (θ3) of plus or minus 15 to 20 degrees with the longitudinal line L1 as the center point.

Further, the extension lengths of the first weakened slit 432 a , the second weakened slit 432 b and the third weakened slit 432 c are equal to the distance between the corresponding two adjacent connecting ribs 431 . The description in this paragraph is only to illustrate the structural significance of the first weakened slit 432a, the second weakened slit 432b, and the third weakened slit 432c from another perspective. In fact, each of them is two adjacent connecting ribs. 431 is the opposite boundary of the separation distance Customizer.
