Description

SPECIFICATION Improved thermo-sealable plastic container The present invention concerns a sealable plastic container for a plurality of small sized commodities such as medicine tablets, electronic accessories, cosmetics and the like.
More particularly, the present invention concerns an improved thermo-sealable container consisting of a body of a sheet of plastic material having a number of certain shaped recesses thereon for receiving commodities and flat edge portion surrounding the recesses, and a thin flexible cover adapted to cover the body; in which at least one part of the cover is adhered to or connected with the corresponding flat portion of the body.
Recently, most developed countries are tending to adapt automatic machines to proceed the integrated operation for packaging the small sized commodities. Fig. 1 shows a brief flow chart of one of the conventional thermo-sealing packaging process in which a continuous plastic sheet is first fed into a first hot press 1 to form a plurality of recesses thereon so as to receive respectively a commodity therein after through a filler 2, then, then another flexible plastic sheet 3 is fed into a second hot press 4 for sealing with the former sheet to form a sealed container, and finally, a suitable length of the sealed container is formed by a cutter 5. Although it obtains a very high efficiency in production, it relatively needs a large amount of investment on the equipment.
Therefore, it is not suitable for a middle or small sized factory.
Fig. 2 shows a perspective view of a container which is commonly used in middle or small factories for packaging small quantity of and tinysized commodities. The container comprises a body 21 having a number of recesses therein, and a separate cover 22. Since the body 21 and the cover 22 are supplied by a specialized factory, the middle or small factory does not need accordingly the first hot press to form recesses on the body 21. However, sealing of this conventional container, on one hand, must be completed by a larger hot press due to the considerable length of the body 21 and the cover 22; on the other hand, alignment of the body and the cover is not readily completed during the sealing process so that the production speed may be reduced.
Accordingly, it is a primary object of the present invention to provide an improved plastic thermosealable container in which a cover is readily aligned with a body thereof during the sealing process.
It is another object of the present invention to provide an improved plastic thermo-sealable container which is particularly suitable for a middle or small factory.
It is a further object of the present invention to provide an improved plastic thermo-sealable container which can be sealed by a smaller hot press so as to reduce the initial investment and the occupied space.
According to the present invention, there is provided a container consisting of a first sheet of plastic plate having a number of certain shaped recesses thereon, and a second sheet of flexible thin plastic plate which is corresponding to and coverable with the first plate, at least one part or one edge of the second flexible plate is adhered to or connected with the corresponding part or edge of the first plate such that the recesses provided on the first plate may be exposed by lifting the second flexible plate when desired.
A specific embodiment of the container according to the invention will now be described, by way of example with reference to the accompanying drawing in which: Fig. 1 is an illustrative diagrammatic view of the manufacture process of a conventional thermo sealable plastic container; Fig. 2 is a perspective view of the conventional thermo-sealable plastic container; and Fig. 3 is a perspective view of a preferred embodiment of the present invention.
Referring to Fig. 3, there is shown a preferred container according to the present invention consisting of a first basic plastic plate 31 having a plurality of recesses 311 and flat edge portion 313 surrounding the recesses 311, and a second thin flexible plastic plate 32 which is corresponding to the first plate 31 and used to cover the recesses 311. The size, shape and number of the recesses 311 depend on the actual needs. One of edges 321 of the second flexible plate 32 is preferably connected to the corresponding edge 312 of the first plate 31 by hot pressing or other known skills.
In practice, one may only put the commodities into the recesses 311 of the first plate 31 respectively, and then, seal the edges of the plates 31 and 32 by a relatively hot press without the known cutting process. In addition, the alignment of the plates 31 and 32 can also be easily completed during the sealing process.
1. An improved thermo-sealable plastic container consists of a basic plate having a plurality of recesses thereon and flat edge portion surrounding the recesses, and a flexible plate corresponding to said basic plate for covering the recesses wherein at least one edge of one part of said flexible plate is connected with the corresponding edge or flat portion of said basic plate.
2. An improved thermo-sealable plastic container substantially as hereinbefore described with reference to Figure 3 of the accompanying drawings.

Although it obtains a very high efficiency in production, it relatively needs a large amount of investment on the equipment. Therefore, it is not suitable for a middle or small sized factory. Fig. 2 shows a perspective view of a container which is commonly used in middle or small factories for packaging small quantity of and tinysized commodities. The container comprises a body 21 having a number of recesses therein, and a separate cover 22. Since the body 21 and the cover 22 are supplied by a specialized factory, the middle or small factory does not need accordingly the first hot press to form recesses on the body 21. However, sealing of this conventional container, on one hand, must be completed by a larger hot press due to the considerable length of the body 21 and the cover 22; on the other hand, alignment of the body and the cover is not readily completed during the sealing process so that the production speed may be reduced.

It is a further object of the present invention to provide an improved plastic thermo-sealable container which can be sealed by a smaller hot press so as to reduce the initial investment and the occupied space. According to the present invention, there is provided a container consisting of a first sheet of plastic plate having a number of certain shaped recesses thereon, and a second sheet of flexible thin plastic plate which is corresponding to and coverable with the first plate, at least one part or one edge of the second flexible plate is adhered to or connected with the corresponding part or edge of the first plate such that the recesses provided on the first plate may be exposed by lifting the second flexible plate when desired. A specific embodiment of the container according to the invention will now be described, by way of example with reference to the accompanying drawing in which: Fig. 1 is an illustrative diagrammatic view of the manufacture process of a conventional thermo sealable plastic container; Fig. 2 is a perspective view of the conventional thermo-sealable plastic container; and Fig. 3 is a perspective view of a preferred embodiment of the present invention. Referring to Fig. 3, there is shown a preferred container according to the present invention consisting of a first basic plastic plate 31 having a plurality of recesses 311 and flat edge portion 313 surrounding the recesses 311, and a second thin flexible plastic plate 32 which is corresponding to the first plate 31 and used to cover the recesses 311. The size, shape and number of the recesses 311 depend on the actual needs. One of edges 321 of the second flexible plate 32 is preferably connected to the corresponding edge 312 of the first plate 31 by hot pressing or other known skills. In practice, one may only put the commodities into the recesses 311 of the first plate 31 respectively, and then, seal the edges of the plates 31 and 32 by a relatively hot press without the known cutting process. In addition, the alignment of the plates 31 and 32 can also be easily completed during the sealing process. CLAIMS
