Description

The present invention relates to a combination container formed by combining a container body and a lid body, and more particularly to a fitting type combination container in which the container body and the lid body are fitted and joined to each other.

Many of the existing packaging containers have a structure using plastic or pulp materials, and in recent years, they have become very popular in the storage container or closed container market where the container body can be sealed by attaching a sealing lid, and they are the contents. It can store things well and prevent liquids from leaking out, and has a very wide range of uses, most often in the form of plastic containers.

An important requirement for such a plastic container is robustness and stability after the lid and container are combined. Most of the known plastic combination containers are provided with an undercut portion facing the peripheral edge of the lid to match the protruding portal flange portion on the peripheral edge of the container, but there are usually two such fitting structures. Situation occurs. The first is a situation in which the fitting method is loose and easy to come off, and the second is a situation in which the fitting is too tight and difficult to separate. Regarding the first situation of the combination, the undercut of the lid matches the flange of the container, but the holding force is insufficient and the whole is easily dislodged due to the pressure of the external force, and then it comes off. , The design of the undercut part of the lid often comes off if the removal method is improper due to the weight of the container. Regarding the second situation of the combination, undercuts and flanges that are often seen when implementing, and structural types such as convex and concave parts with hooks are usually designed so that the undercut is too deep or the flange protrudes too much. Or, if the size of the convex portion with the hook is clearly larger than the size of the concave portion, resistance and difficulty will occur when combining this fitting structure, and further, the container body and the lid will be deformed after the combination. Invite. In particular, it is not easy to open and separate the container body and the lid body after combining them with all their might.

Another known fitting structure is a snap body with recesses and protrusions, which is a combination method design that uses the difference in size to push in when faces of the same shape come into contact with each other. Yes, its resistance is large, it is not easy to combine and separate, and by applying force to the fitting structure of the concave part and the convex part by the pressing method, even if it can be combined smoothly at the beginning, it is a related structure. If the pressing reinforcement is not applied to the body, it becomes difficult to combine the fitting structure due to the deformation of the fitting structure due to the pressing force during actual use. However, since the known technique is a snap design for the purpose of sealing only in consideration of hindering the removal from the mold, the technique of providing the snap body on the side wall surface of the plastic container cannot be escaped. Therefore, the known mating structure usually has structural deformation, combination or separation after being taken out from the mold in the manufacturing process, or the mating structure is pressed with force to be combined or forcibly separated.

Furthermore, by using drawings at the same time, these technical features can be honored.

First, the specific structures of all the elements of the mating type combination container in the first embodiment of the present invention will be described in detail, so please refer to FIGS. 1 and 2.

In this embodiment, the mating type combination container is made of a pulp or plastic material and is composed of a combination of the container body 1 and the lid body 2 (see FIG. 2). The specific structure of the container body 1 includes a housing portion 11, a rib 12, and at least one bent fitting piece 13. The concave accommodating portion 11 is formed in the center of the container body 1. The rib 12 is formed on the peripheral edge of the top surface opening of the container body 1 and has a design in which the cross section is curved in a gate shape. An inner wall region 14 is formed in a recess inside the outer edge of the rib 12, and the inside of the inner wall region 14 extends upward. The formed portion becomes an inner wall guard 141 and strengthens the structural hardness. In this embodiment, a plurality of the bent fitting pieces 13 are designed to be located relative to each other, and the inside of the inner wall region 14 of the rib 12 is extended upward. A fitting stretched surface 131 is provided at the end, a protruding fitting portion 132 is provided in the center of the surface of the fitting stretched surface 131, and a concave pressing portion 133 is naturally provided on the opposite surface. It is formed. Further, at the portion where the bent fitting piece 13 and the rib 12 are connected, the plastic or pulp material is stretched from the outside to the inside to become thin, thereby forming a flexible fitting piece bent portion 134.

The specific structure of the lid 2 includes a protruding portion 21, an edge portion 22, and at least one trapezoidal fitting groove 23. The raised portion 21 is formed by a side wall surface 25 formed by extending the peripheral edge of the bottom surface 24 of the lid 2 downward, and the accommodating space composed of the raised portion 21 and the accommodating portion 11 accommodates and arranges the contents. Used. The peripheral edge portion 22 is formed on the peripheral edge of the opening on the bottom surface of the lid body 2 and can be covered so as to match the rib 12 of the container body 1. The trapezoidal fitting groove 23 has a structure in which the groove opening is reduced toward the groove bottom, that is, the upper portion is wide and the lower portion is narrow. In this embodiment, a design in which a plurality of trapezoidal fitting grooves 23 are located relative to each other is adopted, and the trapezoidal fitting grooves 23 are formed on the side wall surface 25 on the peripheral edge of the lid 2, and the upper part of the trapezoidal fitting grooves 23 is an opening. At the same time, projecting receiving force reinforcing portions 231 are formed on the opposite wall surfaces, the hardness of the lid 2 can be strengthened, the weight of the lid 2 can be withstood, and the lid body 2 is not easily deformed. Further, the inner bottom surface sandwiched between the two receiving force reinforcing portions serves as an anti-slip surface 233 (see FIG. 3), and when the fitting portion 132 is fitted into the trapezoidal fitting groove 23, the anti-slip effect is firmly caught on the anti-slip surface 233. Will occur and will not come off.

Regarding the recessed space formed by the inner wall region 14 of the present invention, when the container body 1 and the lid body 2 are fitted, the trapezoidal fitting groove 23 is not stopped by the rib 12 on the opening peripheral edge of the top surface of the container body 1. , The position of the trapezoidal fitting groove 23 can be moved downward, and accordingly, the total length of the bent fitting piece 13 can be shortened, the material cost can be reduced, and the fitting piece is too long to hinder the user. You can also reduce the situation. In terms of structural design, the height, which is a basic condition of the lid body 2, can be lowered, and the need for a shallow lid is realized. Further, in order to meet the needs of the market price, it is necessary to use a thinner material for the lid 2, and for that purpose, a material that is too thin is used when the fitting portion 132 is pushed into the trapezoidal fitting groove 23 to be fitted. Then, the trapezoidal fitting groove 23 is crushed backward and fitting becomes difficult. According to the present invention, by providing the structure of the inner wall guard 141, when the trapezoidal fitting groove 23 is crushed backward, the trapezoidal fitting groove 23 is guarded by the inner wall guard 141 and a support is formed, so that the rigidity of the trapezoidal fitting groove 23 can be strengthened.

As shown in FIG. 3, the convex top surface 135 of the fitting portion 132 is made of a plastic or pulp material, and the first contact surface is stretched to form a bent surface, which is strong and trapezoidal fitting when light force is applied. It fits tightly into the groove 23 and is not easily deformed.

When the container body 1 and the lid body 2 are combined, the user presses the pressing portion 133 of the bent fitting piece 13 with force on the fingers, and further bends easily using the fitting piece bending portion 134 and has a trapezoidal shape. It can be connected by fitting the fitting portion 132 into the fitting groove 23 and fixing the fitting portion 132. On the contrary, when it is desired to separate the container body 1 and the lid body 2, if the fitting extension surface 131 is used as a receiving force portion at the time of separation, the fitting portion 132 can be easily removed from the trapezoidal fitting groove 23.

On the other hand, when it is desired to open the lid 2 at the time of use, normally, if only one set of the folding fitting pieces in the fitting structure is left without removing the fitting portion 132 of the folding fitting piece from the opposing trapezoidal fitting groove 23, the folding fitting piece The fitting piece bent portion 134 plays a role of connecting the lid body 2, can rotate 90 degrees or 180 degrees, forms a state in which the fitting type combination container is open, makes it easy to take out the contents, and makes all the fitting structures. It is very convenient to use because it does not need to be separated at the same time.

Further, by matching the fitting structure of the present invention with the design in which the rib 12 of the container body 1 and the edge portion 22 of the lid body 2 are mutually covered and matched, the fitting type combination container can be tightly coupled. Even if you put small ingredients such as rice and noodles in the container, you don't have to worry about the contents leaking out when you turn it over. Further, when using the fitting type combination container of the present invention, even if the fitting type combination container is inverted to replace the vertical position of the lid body 2 and the container body 1, a tight coupling combination can be achieved.
