Abstract
Description
- The present invention relates to a non-plastic container for storing food, and in particular to an improved non-plastic container for storing food in which a lid fabricated using plastic based on an injection molding method is sealingly engaged to a non-plastic container body formed of a heat resisting glass, a stainless material, a heat resisting ceramic ware, etc.
- Generally, a container body of a container capable of storing foods is formed of a plastic material approved for storing foods, a heat resisting glass, a heat resisting ceramic ware, a stainless material, etc. A lid detachably engaged to an opening of a container body formed of the above material is generally formed of a plastic material.
- The plastic lid has a certain engaging structure capable of sealing engaging an opening of a container body for stably storing foods stored in the container body. Recently, a plastic lid capable of storing foods stored in the container body in a sealed state without any leakage has been developed. For example, in the case of a food storing container with the
Korean patent No. 335718 - In the case of the locking protrusion engaged to the locking hole formed in the locking wing of the lid, the locking protrusion is integrally formed in the container body by the injection molding method. However, it is impossible to form any protrusion in the container body formed of a heat resisting tempered glass, stainless or heat resisting ceramic ware that is a non-plastic material, the lid having the locking wing is not adapted to the non-plastic container body.
- Therefore, in the case of glass, it has a melting point largely higher than the melting point of the plastic, and it is impossible to obtain a desired flexibility in a melted state, the injection molding is impossible as compared to the plastic product. In addition, a mass production is impossible. In addition, a product made of glass does not have a complicated shape and has a small thickness difference. It is impossible to form a complicated shape having a thin thickness at an outer surface of the product. In the case that there is a large thickness difference in the glass product, the product may be broken or may have cracks during a cooling process after molding by a contraction difference during the cooling process.
- In the case of the stainless material, it has a very high strength and does not have any rusts. However, a molding property is very bad due to its high strength. It is impossible to form a product having protrusions.
- Therefore, in the cases of the non-plastic container body formed of glass, stainless material or ceramic ware and the plastic lid formed by the injection molding method, the engaging method of the locking hole and the locking protrusion is not adapted. Namely, the structure of Figure 10 is adapted.
- The construction of the conventional container will be described. The
non-plastic container body 100 includes anengaging shoulder 101 having a small size and protruded from an outer portion of the opening of the same. Theplastic lid 200 includes acover part 201 for covering thecontainer body 100, acontact part 202 contacting with the opening of the container body, a coveringpart 203 for covering an outer side of the opening of the container body, a plurality ofextension parts 204 downwardly extending from the portion opposite to the coveringpart 203 and flexibly extending in the direction of the outer side, and anengaging protrusion 205 protruded from the inner surfaces of theextension parts 204 and elastically engaged and disengaged with theengaging shoulder 101 of thecontainer body 100. - However, in the above described storing container, when the
lid 200 is engaged to the opening of thecontainer body 100, when theengaging protrusions 205 protruded in the direction of the opposite inner surfaces of theextension parts 204 are pressed and get close in the direction of thecontainer body 100, theengaging protrusion 205 is elastically engaged to theengaging shoulder 101, and thelid 200 is engaged to thecontainer body 100. However, since theengaging protrusion 205 is engaged to the engaging shoulder by an elastic recovering force of theextension part 204 itself, the engaging force is weak, and thelid 200 is pulled in the direction of thecontainer body 100, so that it is impossible to obtain a desired sealing force. Therefore, the lid is easily disengaged. Therefore, the storing container formed of thenon-plastic container body 100 and theplastic lid 200 cannot stably store the foods in thecontainer body 100. -
CA-A-2,314,537 relates to a container comprising a base and a lid, wherein the lid can be locked hermetically to the base by at least one locking means, wherein sealing means are provided between the lid and the base. -
US-A-5,785,198 relates to a twist-on/twist-off resealable assembly for an existing can end, wherein a collar surrounds the exterior surface of the can adjacent the open end, the collar including a can mating finish of an inner surface thereof and a closure engaging finish on an outer surface thereof. - Accordingly, it is an object of the present invention to provide a non-plastic container for storing food that overcomes the problems encountered in the constructions between the non-plastic container body formed of glass, stainless or ceramic ware and the plastic lid.
- It is another object of the present invention to provide a non-plastic container for storing food capable of enhancing an engaging force between a non-plastic container body formed of glass, stainless, ceramic ware, etc. and a plastic lid for thereby largely increasing a sealing property therebetween. In addition, it is possible to stably store foods based on a high strength and high heat-resisting property of a container body.
- To achieve the above objects, there is provided a food storing container formed of a non-plastic container body formed of glass, stainless, ceramic ware, etc., and a plastic lid formed of plastic, a food storing container having a non-plastic container body comprising a closed ring shaped plastic rim formed in an upper side of an opening of the non-plastic container body wherein the closed ring shaped plastic rim surrounds all outer surrounding portions of the container body; and at least more than locking protrusion integrally formed at the opposite sides of the plastic rim wherein the locking protrusions are inserted into locking holes formed in locking wings of the plastic lid.
- The plastic rim is formed based on a double injection method in a state that the container body is inserted into a plastic injection molding.
- An engaging groove may be formed on an outer surface of the upper side of the opening of the non-plastic container body for enhancing an engaging force with the plastic rim.
- When forming the plastic rim in the container body based on the double injection method, a plastic coating layer is integrally formed with the plastic rim wherein the plastic coating layer surrounds the outer surface and lower portions of the container body.

- In the drawings,
reference numeral 1 represents a non-plastic container body, and 2 represents a plastic lid. Here, thenon-plastic container body 1 is formed of glass or stainless having a low molding property and a high heat resisting property or ceramic ware, and theplastic lid 2 is formed of a plastic material. In addition, thecontainer body 1 and thelid 2 are fabricated separately from each other. - In the present invention, the
non-plastic container body 1 is fabricated using glass or stainless or ceramic ware. The thusly fabricatednon-plastic body 1 is inserted into a plastic injection molding. Aplastic rim 3 is formed in such a manner that the outer portions of theupper part 11 of the opening of thecontainer body 1 is fully surrounded by a double injection method. Alocking protrusion 31 is integrally formed at the opposite portions in therim 3 in such a manner that at least more than one locking protrusion in each portion or one locking protrusion in each surface of the container body. - A closed ring shaped
plastic rim 3 having thelocking protrusion 31 formed in the above manner is formed by an injection molding method and is inserted into an outer portion of thecontainer body 1. At this time, theplastic rim 3 has a tension force, so that it is not easily disengaged. - In addition, when forming the
non-plastic container body 1, an engaginggroove 12 is formed at theupper portion 11 of the opening. When engaging theplastic rim 3 is to the outer portion of thecontainer body 1 by the double injection method, theplastic rim 3 is inserted into the engaginggroove 12 for thereby enhancing the engaging force of theplastic rim 3. The above construction method is adapted to the method that theplastic rim 3 is inserted and engaged. - In addition, when the plastic rim is processed by the double injection method in a state that the
non-plastic container body 1 is inserted into the plastic injection molding, aplastic coating layer 32 is integrally formed in such a manner that it surrounds the outer surface and entire lower portions of thecontainer body 1 of the lower side of therim 3. Therefore, it is possible to maintain a desired strength and heat resisting property. In addition, the outer construction of the container body may have various different colors and shapes. - Here, the
plastic lid 2 is formed by an injection molding using a plastic material to correspond to the shape of thecontainer body 1. Thelid 2 includes acover part 21 formed in a plane shape, and anengaging part 22 engaged to the opening of thecontainer body 1. A lockingwing 23 is formed in a surrounding portion of thelid 2 and is smoothly folded and unfolded along a hinge line. At least one lockingwing 23 is formed in the opposite surfaces or the lockingwing 23 is formed in each surface of thecontainer body 1. A lockinghole 24 into which the lockingprotrusion 31 is inserted is formed in each lockingwing 23. - A sealing packing 4 formed of a silicon material is engaged in the inner side of the
engaging part 22 of theplastic lid 2. - The operation of the present invention will be described as follows.
- Figure 1 is a view illustrating the
plastic container body 1 formed in a rectangular shape wherein each side has a rounder corner. In this embodiment of the present invention, theplastic rim 3 having the lockingprotrusion 31 is formed in the outer surface of theupper portion 11 of the opening of thecontainer body 1 by the double injection method. - The
plastic rim 3 formed in thenon-plastic container body 1 maintains engaged to theupper portion 11 of the container body by an adhering force of the plastic itself and a contraction operation after the double injection. Therefore, even when theplastic lid 2 is repeatedly engaged and disengaged for many times, theplastic rim 3 is not separated from thecontainer body 1. - In addition, when engaging the
plastic lid 2 to thenon-plastic container body 1, as shown in Figure 3, the surrounding portion of the opening of thecontainer body 1 contacts with the sealing packing 4 engaged in the engagingpart 22 of thelid 2, and the lockingwing 23 formed in thelid 2 is rotated in the direction of thecontainer body 1, and the lockingwing 23 is pressed to thecontainer body 1, so that the lockinghole 24 is engaged to the lockingprotrusion 31. At this time, the protrusion position of the lockingprotrusion 31 is at the portion in which the lockingwing 24 of the lockingwing 23 is slightly moved in the lower direction and is elastically and rightly engaged. Therefore, when the locking holes 24 of each lockingwing 23 are inserted onto the lockingprotrusions 31 and are engaged thereby, thelid 2 itself is slightly moved down in such a manner that thelid 2 elastically presses the surrounding portions of the opening of thecontainer body 1. Therefore, the sealing packing 4 engaged to the engagingpart 22 is elastically pressed for thereby sealing the opening of thecontainer body 1. Therefore, it is possible to engage theplastic lid 2 to thenon-plastic container body 1 in a sealed state. - In addition, when separating the
plastic lid 2 that is engaged to thenon-plastic container body 1 in a sealed state, each lockingwing 23 engaged to the lockingwings 31 is disengaged, so that the locking holes 24 are escaped from the lockingprotrusions 31 for thereby disengaging thelid 2. - As shown in Figure 4, in the embodiment of the present invention, when the
non-plastic container body 1 is molded using glass, stainless or ceramic ware as a source material, an engaginggroove 12 is formed in a concave shape on an outer surface of theupper portion 11 of the opening, and thenon-plastic container body 1 having the engaginggroove 12 is inserted into the injection molding, and the process is performed in a state that theplastic rim 3 is engaged to the engaginggroove 12 by the double injection method, so that theplastic rim 3 is more stably engaged. When the engaginggroove 12 is formed in thecontainer body 1, even when theplastic rim 3 is engaged by a simple insertion and adhering method, not by the double injection method, it is possible to obtain a desired stability. - As shown in Figure 5, in the embodiment of the present invention, the
non-plastic container body 1 is formed of glass, stainless or ceramic ware, and thecontainer body 1 is inserted into the injection molding for engaging theplastic rim 3 based on the double injection method. Aplastic coating layer 32 is integrally extended from theplastic rim 3 for thereby surrounding the outer surface and lower (bottom) of thecontainer body 1. In the above embodiment of the present invention, theplastic lid 2 is engaged in a sealed state, and theplastic coating layer 32 surrounds the entire portions of thenon-plastic container body 1, so that it is possible to protect thecontainer body 1 from an external impact. In addition, it is possible to express various colors and shapes for thereby enhancing an outer look of the container. - In addition, as it is not shown in the drawings, in the case that the
non-plastic container body 1 is formed in a circle shape, theplastic rim 3 may be inserted and adhered or theplastic rim 3 and the lockingprotrusion 31 may be integrally formed at the upper portions of the opening of the container body by the double injection method using plastic. In addition, theplastic coating layer 32 may be integrally formed and may surround the entire portions of the container body. - As described above, the plastic rim having the locking protrusions is inserted and engaged to the non-plastic container body formed using glass (including heat resisting tempered glass), stainless or ceramic ware (including heat resisting ceramic ware) or the plastic rim is formed by the double injection method. In addition, the lid is formed of plastic material, and the container body is formed of a material having a high strength and heat resisting property. Therefore, any scratches are not formed on the surfaces of the container, and the products are stable. It is possible to fabricate a container having a heat resisting property. A stable and strong sealing state is achieved between the lid and the container body. In a state that the lid is engaged, the lid is not easily disengaged from the container body, so that it is possible to stable store foods.
- In addition, in the case of the container body formed of transparent glass, the inner side of the container may be seen. It is possible to fabricate the container body having various colors and shapes. In the case that the outer side of the container body is coated using plastic material, it is possible to achieve various colors and shapes. The food storing container formed of the non-plastic container body and the plastic lid may be fabricated in various colors and shapes, so that the quality of the container is enhanced.
- As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
