Definitions

  • the present invention relates generally to a container, and more particularly to a container that prevents illegal operations and can be easily identified after being illegally operated.
  • Thin-wall plastic containers are normally produced by vacuum forming. There are a variety of such containers in the marketplace. They are made into different shapes, such as the shape of a box, a cup, or a bowl, and are very suitable to be used as packaging containers for instant food (e.g. cooked food or peeled fruits). Apart from the advantages of low production cost and recyclability, their transparent design allows consumers to clearly see the food held inside.
  • a conventional container usually has a box body and a cover body.
  • the box body and the cover body can either be integrally formed, connected to each other on one side, or be separately formed.
  • the cover body in order for the cover body to seal the box body to keep the food fresh during exhibition, there are usually matching configurations of concave and convex portions on the box body and the cover body to fix them together. Such configurations facilitate packaging and allow repeated opening and closing.
  • Some other manufacturers have developed a kind of container that allows consumers to pull open the container only from a preset buckle portion and pull tab between the box body and cover body of the container. Once the pull tab is pulled open, the buckle portion will break due to the design of a ring tear line on its periphery and be retained in a slot, so that the market management or the checkout staff can identify if the container has been illegally opened.
  • Such a conventional structural design allows repeated usage, and can avoid damages of other parts of the container.
  • identification of illegal opening is still not easy. Even if the pull tab is pulled open, it may be recovered due to the elasticity of plastics, and because most containers are made of transparent plastics, the breakage of the buckle portion may not be easily identified.
  • the pull tab may also be recovered to its original position and flat state.
  • the transparency of the container will further make it difficult for market management and checkout staff to identify if the buckle portion has been opened. Therefore, such a design still has not perfectly solved the problem that illegal opening of the container cannot be easily identified.
  • the connecting ribs of the ring tear line are usually designed with even interval distributions. Therefore, when the pull tab is pulled, the resistance points are relatively evenly distributed. As a result, after opening, when the pull tab turns up under the resistance of the connecting ribs, it will have a smooth bending. Such a smooth bending state may add to the difficulty in identification of illegal opening. So the design should be improved.
  • the main object of the present invention is to provide a container that prevents illegal operations and can be easily identified after being illegally operated. It aims to make a breakthrough and creatively solve the technical problems in developing a new structural design of a container product that will be ideal and practical.
  • the container comprises:
  • FIG. 1 is a perspective view 1 of a preferred embodiment of the container according to the invention, showing the state wherein the cover body is opened.
  • FIG. 2 is a perspective view 1 of a preferred embodiment of the container according to the invention, showing the state wherein the cover body is closed.
  • FIG. 3 is a top view corresponding to FIG. 2 .
  • FIG. 4 is a 4-4 sectional view of FIG. 3 .
  • FIG. 5 is an enlarged view of the pull tab portion of the preferred embodiment of the invention.
  • FIG. 6 is a perspective view of the pull tab according to the invention when it is not pulled up.
  • FIG. 7 is a perspective view of the pull tab according to the invention when it is pulled up.
  • FIG. 1 to FIG. 6 illustrate a preferred embodiment of a container that prevents illegal operations and can be easily identified after being illegally operated.
  • FIG. 1 to FIG. 6 illustrate a preferred embodiment of a container that prevents illegal operations and can be easily identified after being illegally operated.
  • such an embodiment is for the purpose of illustration only and is not intending to limit the scope of the invention.
  • the container comprises: a box body 10 , including an opening 11 and a first joining edge 12 configured around the opening 11 ; a cover body 20 , optionally covering the opening 11 of the box body 10 , the periphery of said cover body 20 configured with a second joining edge 22 to fit the first joining edge 12 configured on the box body 10 ; a pull tab 30 , formed on the second joining edge 22 of the cover body 20 , protruding outward, said pull tab 30 including an external end edge 31 and two side edges 32 ; a tension-breaking type buckle member 40 , including a buckle convex portion 41 configured on the pull tab 30 , a buckling slot 42 configured at a position on the box body 10 for the buckle convex portion 41 to align and fix, and a ring tear line 43 configured on the periphery of the buckle convex portion 41 , thus, when the pull tab 30 is pulled, the ring tear line 43 will break and leave the buckle convex portion 41 in the buckling slot 42 , said ring tear line 43 including
  • the peripheral area of the buckle convex portion 41 of the pull tab 30 and the peripheral area of the buckling slot 42 of the box body 10 are pushed together face to face.
  • the pull tab 30 protrudes outside the first joining edge 12 of the box body 10 to facilitate pulling
  • the ring tear line 43 is correspondingly configured inside the first joining edge 12 of the box body 10 .
  • a longitudinal line L 1 is defined, and the center of the ring tear line 43 further defines a horizontal line L 2 , said horizontal line L 2 and said longitudinal line L 1 being orthogonal to each other.
  • a pull tab strength weakening portion 50 configured on the structure of the pull tab 30 , is formed in a flat state, capable of bending, wherein the ring tear line 43 is configured around the periphery of the buckle convex portion 41 at an interval, so that the pull tab strength weakening portion 50 is constituted by the narrow area existing between the ring tear line 43 and the side edge 32 of the pull tab 30 , said pull tab strength weakening portion 50 being used to cause the pull tab 30 to have a bent portion when pulled up, so that the pull tab 30 will turn up for easy identification; a weakening strength unit of the tear line, at least including a first weakening slit 432 a , said first weakening slit 432 a formed on the two sides of the ring tear line 43 close to the two side edges 32 of the pull tab 30 , the extension length of said first weakening slit 432 a being between the angle range ( ⁇ 1) of plus or minus 15 to 20 degrees with the horizontal line L 2 as the center point.
  • the actual application of the present invention of a container that prevents from an illegal operation and can be easily identified after being illegally operated is as shown in FIG. 5 .
  • the differentiated intervals of the weakening slit of the weakening strength unit of the tear line will cause the strength weakening portion 50 of the pull tab to have a bending state different from other parts of the pull tab 30 . That is to say, when the pull tab 30 is pulled up, as illustrated in FIG. 6 and FIG. 7 , there is a change of state.
  • the pull tab 30 When acting on the section where the intervals between the connecting ribs 431 and slits 432 are normal, the pull tab 30 will curve upward to a certain degree under the resistance from the connecting ribs 431 .
  • the pulled and up-turning state of the pull tab 30 can be clearly identified.
  • the connecting ribs 431 will not be too far away from the longitudinal line L 1 , and there will no longer be the problem that the pull tab 30 may break under the excessive resistance from the connecting ribs 431 of the ring tear line 43 , and the operation of the pull tab 30 will be more convenient and easier.
  • the conventional structure normally arranges 2 to 4 connecting ribs.
  • the resistance from the connecting ribs against the pulling of the pull tab 30 is the strongest, and it is the most difficult to break the connecting ribs.
  • the reason is that, apart from the positions of the connecting ribs that are far away from the pulled position, causing inefficient transmission of the pulling force, the connecting ribs here will be kind of twisted under the pulling force, and the elastic and resilient plastics will not be easily broken under the twisting. Therefore, the resistance in this section is strongest and may cause cracking of the pull tab 30 .
  • the present invention adopts the technical feature to form a first weakening slit 432 a on the ring tear line 43 to overcome the existing problem.
  • the weakening strength unit of the tear line further includes a second weakening slit 432 b , said second weakening slit 432 b formed at the side of the ring tear line 43 close to the external end edge 31 of the pull tab 30 , the extension length of the second weakening slit 432 b being between the angle range ( ⁇ 2) of plus or minus 15 to 20 degrees with the longitudinal line L 1 as the center point.
  • the weakening strength unit of the tear line further includes a third weakening slit 432 c , said third weakening slit 432 c formed at the side of the ring tear line 43 away from the external end edge 31 of the pull tab 30 , the extension length of the third weakening slit 432 c being between the angle range ( ⁇ 3) of plus or minus 15 to 20 degrees with the longitudinal line L 1 as the center point.
  • the extension lengths of the first weakening slit 432 a , the second weakening slit 432 b and the third weakening slit 432 c are equal to the distances between their respective neighboring connecting ribs 431 .
  • the descriptions here are to explain the different structural designs of the first weakening slit 432 a , the second weakening slit 432 b and the third weakening slit 432 c from another perspective. In fact, they are all relatively defined by the intervals between two neighboring connecting ribs 431 .
