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 to each other and coupled.

Many of the existing packaging containers have a structure that uses plastic or pulp materials, and in recent years, they have become very popular in the market for storage containers or sealed containers that can seal the container body by attaching a sealing lid. It can store things well and prevent liquid from leaking out, and it has a very wide range of uses, the most common being the form of plastic containers.

An important requirement for such a plastic container is toughness and stability after combining the lid and the container. Most of the known plastic combination containers are provided with an undercut portion that faces the peripheral edge of the lid body and are fitted to the projecting gate-shaped flange portion of the peripheral edge of the container body. Occurs. The first is a situation in which the fitting method is loose and it is easy to come off, and the second is a situation in which the fitting is too tight and separation is difficult. Regarding the first situation of the combination, the undercut of the lid body matches the flange portion of the container body, but the holding force is insufficient, and the whole body is pressed by external force and deforms. The design of the undercut portion of the lid often comes off due to the weight of the container if the removal method is inappropriate. Regarding the second situation of the combination, the undercut and the flange that are often seen when carrying out the structure, the design type such as the convex portion and the concave portion with the catch are usually designed so that the undercut is too deep or the flange is too protruding, Or, if the size of the protruding convex part that is caught is obviously larger than the size of the concave part, resistance and difficulty will occur when combining this fitting structure, and further the deformation of the container body and lid body after combination. Invite. In particular, it is not easy to open and separate the container body and the lid body after the combination is exhausted.

In order to clearly disclose the technical features of the fitting type combination container of the present invention, the technical features of the present invention will be described in detail below with reference to some embodiments. Furthermore, these technical features can be recognized by using the drawings at the same time.

First, since the detailed structure of all the elements of the fitting type combination container in the first embodiment of the present invention will be described in detail, please refer to FIG. 1 and FIG.

In this embodiment, the fitting type combination container is made of 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, ribs 12 and at least one folding fitting piece 13. The concave housing portion 11 is formed in the center of the container body 1. The rib 12 is formed in the peripheral edge of the top surface opening of the container body 1 and has a design in which the cross section is warped in the shape of a gate. The formed part becomes the inner wall guard 141 and strengthens the structural hardness. In the present embodiment, the folding fitting piece 13 is designed such that a plurality of them are located opposite to each other, and the inside of the inner wall region 14 of the rib 12 is extended upward. A fitting extension surface 131 is provided at the end, a fitting portion 132 is provided at the center of the surface of the fitting extension surface 131, and a concave pressing portion 133 is naturally formed on the other opposite surface. It is formed. In addition, a portion where the bending fitting piece 13 and the rib 12 are connected to each other forms a fitting piece bending portion 134 which is easy to bend by the plastic or pulp material being drawn from the outside to the inside to be thin.

The specific structure of the lid body 2 includes a protruding portion 21, a peripheral portion 22 and at least one trapezoidal fitting groove 23. The raised portion 21 is formed by a side wall surface 25 formed by the peripheral edge of the bottom surface 24 of the lid 2 extending downward, and the storage space formed by the raised portion 21 and the storage portion 11 is used for storing or arranging contents. Used. The edge portion 22 is formed on the peripheral edge of the opening on the bottom surface of the lid body 2 and can be fitted and covered with the rib 12 of the container body 1. The trapezoidal fitting groove 23 has a structure that decreases from the groove opening toward the groove bottom, that is, the upper portion is wide and the lower portion is narrow. In the present embodiment, a design in which a plurality of trapezoidal fitting grooves 23 are positioned opposite to each other is adopted, and is formed on the side wall surface 25 at the peripheral edge of the lid body 2. The upper side of the trapezoidal fitting groove 23 is an opening. In addition, the force receiving reinforcing portions 231 projecting from the opposite side wall surfaces are formed, so that the hardness of the lid body 2 can be strengthened, the lid can bear the weight to be overlaid, and is not easily deformed. In addition, the inner bottom surface sandwiched between the two force receiving reinforcement portions serves as a slip prevention surface 233 (see FIG. 3), and when the fitting portion 132 is fitted into the trapezoidal fitting groove 23, the slip prevention effect is obtained in which the slip prevention surface 233 is firmly caught. 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 together, 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 the total length of the bending fitting piece 13 can be shortened accordingly, not only the material cost can be reduced, but also the fitting piece is too long, which hinders the user. It can reduce the situation. In terms of structural design, it is possible to reduce the height, which is a basic condition of the lid body 2, 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 body 2. Therefore, when the fitting portion 132 is pushed into the trapezoidal fitting groove 23 and is fitted therein, an excessively thin material is used. Then, the trapezoidal fitting groove 23 is crushed rearward, which makes fitting 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, it is protected by the inner wall guard 141 and a support is formed to enhance the rigidity of the trapezoidal fitting groove 23. The need for a lid made of thin material can be realized.

Please refer to FIG. 3 and FIG. 4 for describing a state in which the fitting type combination container in the first embodiment of the present invention is combined.

In the present embodiment, the bent fitting piece 13 of the container body 1 is interconnected with the inner wall region 14 of the rib 12 by using the fitting piece bending portion 134, and can be freely bent. As shown in FIG. 3, the convex top surface 135 of the fitting portion 132 is made of plastic or pulp, and the first contact surface forms a curved surface by stretching, and its strength is strong. It fits tightly in the groove 23 and is hard to deform.

When the container body 1 and the lid body 2 are combined, the user applies force to the fingers to press the pressing portion 133 of the bending fitting piece 13 and further easily bends using the fitting piece bending portion 134, and also trapezoidal shape. The fitting portion 132 can be joined by being fitted and fixed in the fitting groove 23. 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 force receiving 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 body 2 at the time of use, normally only one set 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 fitting piece bending portion 134 plays a role of connecting the lid body 2, can rotate 90 degrees or 180 degrees, forms the opened state of the fitting type combination container, makes it easy to take out the contents, and fits all fitting structures. It is very convenient to use because it does not need to be separated at the same time.

Further, by fitting the fitting structure of the present invention to the design in which the rib 12 of the container body 1 and the edge portion 22 of the lid body 2 are covered and matched with each other, the fitting structure can be tightly coupled, and a fitting type combination container. Even if you put small ingredients such as rice and noodles in, you do not have to worry that the contents will leak if you turn it over. Further, when the fitting type combination container of the present invention is used, even if the fitting type combination container is inverted and the upper and lower positions of the lid body 2 and the container body 1 are replaced, a tight coupling combination can be achieved.

Please refer to FIG. 5 and FIG. 6 for a detailed description of the method of tightly fixing the fitting portion 132 in the trapezoidal fitting groove 23 in this embodiment.

In practice, the trapezoidal fitting groove 23 provides a fitting space for the fitting portion 132, and this space has two force receiving reinforcing portions 231 in the form of protrusions and a slip prevention surface 233 (FIG. 1 and FIG. 3), the diameter size of the fitting portion 132 is slightly larger than the size of the depression between the two opposing force receiving reinforcement portions 231 of the trapezoidal fitting groove 23. As a result, when the fitting portion 132 is fitted into the trapezoidal fitting groove 23, an effect of fitting and fixing is obtained, and the slip preventing surface 233 is firmly hooked to each other to prevent slipping. Further, due to the structure in which the upper portion of the trapezoidal fitting groove 23 is wide and the lower portion thereof is narrow, when the fitting type combination container is pressed by an external force, the fitting portion 132 and the trapezoidal fitting groove 23 are conversely tightly fitted to each other, which makes it difficult to open. It will not become loose and unstable. In particular, the upper side of the trapezoidal fitting groove 23 is an opening, and the side wall surface of the force receiving reinforcing portion 231 has an inclined surface with a positive draft angle, so that it is possible to perform a molding operation such as putting it in the mold or removing it from the mold at the time of manufacturing. It is easy to perform, and due to the design of this positive draft, it is not deformed at the time of mold release after molding. (If deformed by mold release, the effect of being pushed in and engaged when the fitting portion 132 is fitted is obtained. Hateful). The lower anti-slip surface 233 can prevent the fitting portion 132 from slipping out or coming off even when the fitting type combination container is turned upside down or shaken. The force-reinforcing portions 231 on both sides are formed of two convex shapes, and have a large number of curved surfaces at the time of press molding, so that the hardness is strengthened, and a sufficient supporting force is achieved to achieve the press-fitting of the fitting portion 132.
