1. Field of the Invention
The present invention relates to a container, and more particularly to a container that prevents illegal operation and can be easily identified after being illegally operated.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
Vacuum-formed plastic containers are usually made to have a box-shaped or a cup-shaped containing structure and are used in supermarkets for keeping food fresh. The plastic containers are transparent for the buyer to clearly see the contents, such as jelly-like, fruit or liquid foods and are provided to stimulate customer's buy intent. For containing liquid foods, the conventional plastic containers focus on the function of water-tight seal. The conventional plastic container usually includes a hollow body and a body for selectively closing the hollow body.
The conventional plastic containers are provided for containing instant foods. However, the conventional plastic container provides no function to stop illegal operation. The tamper-resistant/evident structures are very important for deterring theft and preventing the loss of product and income for the seller, as well as instilling consumer confidence in the integrity of the contents within the container and confidence in the ability of the seller and/or manufacturer to provide and maintain quality goods.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional container used in the supermarket for containing fresh foods.
The main objective of the present invention is to provide an improved container that prevents illegal operation and can be easily identified after being illegally operated.
To achieve the objective, the container in accordance with the present invention comprises a bowl-shaped base including an opening defined therein and a stair-shaped first locking structure surrounding the opening. The first locking structure is sequentially divided into a vertical portion and a horizontal portion, wherein a peripheral wall outwardly extends from an edge of the horizontal portion and a first protrusion laterally extends from the horizontal portion of the first locking structure. A cavity is defined in the first protrusion, wherein the cavity has an -shaped cross-section (upside down capital omega symbol).
A cover selectively closes the opening of the bowl-shaped base and includes a stair-shaped second locking structure peripherally formed thereon, wherein the first locking structure and the second locking structure are complementally and air-tightly connected to each other when the cover closing the bowl-shaped base. The second locking structure is sequentially divided into a vertical portion and a horizontal portion, wherein a second protrusion laterally extends from the horizontal portion of the second locking structure and an edge of the horizontal portion of the second structure extends toward an abutment between the peripheral wall and the horizontal portion of the first locking structure when the cover closing the bowl-shaped base. A pre-broken structure is formed on the second protrusion and includes a snapper formed on a back of the of the second protrusion and having an -shaped cross-section. The snapper is engaged into the cavity when the cover closing the bowl-shaped base. A pre-broken line is formed on the second protrusion and surrounding the snapper, wherein the pre-broken line is damaged after detaching the cover from the bowl-shaped base.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The bowl-shaped base 10 has an opening (not numbered) defined therein and a stair-shaped first locking structure 11 surrounding the opening. The first locking structure 11 is sequentially divided into a vertical portion 111 and a horizontal portion 112, wherein a first locking portion 12 is peripherally formed on the vertical portion 111. A peripheral wall 13 outwardly extends from an edge of the horizontal portion 112 and has a rib 131 peripherally formed thereon. A first protrusion 14 laterally extends from the horizontal portion 112 of the first locking structure 11. A recess 15 is defined in the first protrusion 14 and a cavity 16 is defined in a bottom of the recess 15, wherein the cavity 16 has an -shaped cross-section.
The cover 20 is provided to selectively close the opening in the bowl-shaped base 10. The cover 20 includes a stair-shaped second locking structure 21 peripherally formed thereon. The first locking structure 11 and the second locking structure 21 are complementally and air-tightly connected to each other when the cover 20 closing the bowl-shaped base 10. The second locking structure 21 is sequentially divided into a vertical portion (not numbered) and a horizontal portion (not numbered), wherein a second locking portion 22 is peripherally formed on the vertical portion of the second locking structure 21, and the second locking portion 22 is complementally and selectively connected to the first locking portion 12 when the cover 20 closing the bowl-shaped base 10. A second protrusion 23 laterally extends from the horizontal portion of the second locking structure 21, wherein the pre-broken structure 30 is formed on the second protrusion 23.
The pre-broken structure 30 includes a snapper 31 formed on a back of the of the second protrusion 23 and having an ?-shaped cross-section. The snapper 31 is engaged into the cavity 16 when the cover 20 closing the bowl-shaped base 10. A pre-broken line 32 is formed on the second protrusion 23 and surrounds the snapper 31, wherein the pre-broken line 32 is contained within an outline of the recess 15. With reference to
