Description

The present invention relates to a container composed of a container body and a lid, and more particularly to an inner fitting container in which the container body and the lid are internally fitted.

Conventionally, a container for storing a liquid such as a dressing to be applied to a salad or the like has been composed of a container body and a lid that can be fitted to the container body, and when the contents such as the liquid are discharged from the container body, The user had to peel off the lid by hand and open it. However, if a strong force is applied when the lid body is peeled off, there is a problem that the contents of the container body are scattered due to the reaction of the lid body being removed.

Therefore, for example, the container of Patent Document 1 is a container in which the fitting bulge of the lid fits into the opening of the container body so that the lid can be easily peeled off, and the fitting bulge of the lid is fitted. A non-bulging part is formed in a part of the protruding part. Since the non-bulging portion is not fitted to the container body, the lid can be easily peeled off from the non-bulging portion as a starting point. Further, when the container is heated in a microwave oven or the like, the steam expanded inside is discharged to the outside from the non-expanded portion, so that the container can be prevented from bursting.

However, in the container of Patent Document 1, while the lid body can be easily peeled off, there is a concern that the contents may leak due to the provision of the non-bulging portion. Therefore, the container of Patent Document 2 is a container in which the lid body fits into the opening of the container body, and the upper opening of the container body has a gradual change opening that gradually narrows toward the front end portion, and the lid body has a gradual change opening. It has a gradual change lid surface portion corresponding to the gradual change opening portion, and has pressing portions on both side surfaces of the lid surface at the rear portion of the gradual change lid surface portion. Then, by pinching the pressing portion inward of the lid surface, the entire gradually changing lid surface portion rises and deforms toward the center thereof, and the tapered front end portion of the gradually changing lid surface portion rises in a mountain shape, and the upper part of the container body is formed. Separated from the front end of the opening, a discharge section for the contents inside the container body is formed. As described above, in the container of Patent Document 2, since the lid body and the container body are firmly fitted during transportation and storage, it is possible to prevent liquid leakage. Then, when it is desired to discharge the contents, the lid body can be easily opened by simply pressing the pressing portion inward of the lid surface.

However, in the container of Patent Document 2, the pressing portion of the lid is extended so as to cover the outside of the upper opening of the container body so that the pressing portion of the lid can be pressed from the outside with a finger or the like. It has become. Therefore, when the pinching portion is pinched with a finger or the like, a wide range around the opening of the container body on the back side of the pinching portion is unnecessarily covered through the pinching portion and the lid surface around the pinching portion. It will be pinched. Then, at the time of pinching, the container body is also greatly deformed, and the contents contained in the container body may be scattered. In addition, since it is necessary to strongly press the pressing portion with a finger or the like so that the entire lid surface rises and deforms toward the center, it is easy to apply extra force, and the reaction when the lid is opened causes the container body to be pressed. There is a risk that the contents contained in the storage will be scattered.

It opens.

Further, the top plate 110 is formed with ribs 160 that are behind the tip lid surface portion 120 and extend in the direction of sandwiching the pressing portion 270, which will be described later. The rib 160 is recessed downward and is formed in a straight line so as to cross both ends of the top plate 110. In this rib 160, the recessed and curved portion is easily elastically deformed and plays a role like a so-called hinge, so that the tip lid surface portion 120 is easily opened widely in the upward direction with the rib 160 as an opening / closing axis.

Further, FIG. 1 (e) shows a modified example of the lid body of the present invention. The configuration of the lid body 100A according to this modification is different from the configuration of the lid body 100 shown in FIGS. 1A to 1D, but the other configurations are basically the configuration of the lid body 100. Since it is the same as, detailed description is omitted. As shown in FIG. 1 (e), the top plate 110A is formed with a step 160A which is behind the tip lid surface portion 120A and extends in the direction of sandwiching the pressing portion 270, which will be described later. The step 160A is recessed downward and is formed in a straight line so as to cross both ends of the top plate 110A. Then, in this step 160A, the recessed and stepped portion is easily elastically deformed and plays a role like a so-called hinge, so that the tip lid surface portion 120A is easily opened widely in the upward direction with the step 160A as the opening / closing axis. ing.

In the lid body 100 shown in FIG. 1, the angle α of the tip 121 of the tip lid surface portion 120 is an obtuse angle of 90 degrees or more, but the angle α is not limited to this and may be an acute angle of 90 degrees or less. Further, the rib 160 or the step 160A is formed in a straight line so as to cross both ends of the top plate 110, but is not limited to this, and extends in the direction of sandwiching the pressing portion to extend the tip lid surface portion 120. Any arrangement and shape can be used as long as it functions as an opening / closing shaft. Further, the rib 160 has a concave shape, but the rib 160 is not limited to this, and may have a convex shape or any other shape as long as it functions as an opening / closing shaft of the tip lid surface portion 120.

Further, the tip lid surface portion 120 is composed of three surface portions 122, a surface portion 123, and a surface portion 124, but the present invention is not limited to this, and the tip lid surface portion 120 may be composed of one or two surface portions, or four or more. It may be composed of a plurality of face portions. Further, the shape of each surface portion is not limited to the shape shown in FIG. 1, and can be any shape.

Next, FIG. 2 shows the container body 200 of the inner fitting container 300 of the present invention. As shown in FIG. 2, the container body 200 has a deep dish shape that opens upward, and has a bottom wall 210 having a substantially polygonal plan view and legs that bulge downward from the side portions 211 of the bottom wall 210. It includes 220 and a side wall 230 formed so as to rise from the leg 220. Further, a concave container-side fitting portion 240 is provided at the upper end of the side wall 230, and a flat flange portion 250 extending in the horizontal direction is provided on the outside of the container-side fitting portion 240. .. The leg portion 220, the side wall 230, the container-side fitting portion 240, and the flange portion 250 are continuously provided over the entire circumference in the circumferential direction of the container body 200.

Further, the front end side 201 of the opening of the container body 200 is a tip opening 260 having a substantially square shape in a plan view in which the tip 261 side gradually becomes thinner. As will be described later, the tip opening 260 has a tapered shape so that the contents in the container body 200 can be easily discharged to the outside. Further, the tip opening 260 and the tip lid surface 120 of the lid 100 have corresponding shapes so as to coincide with each other, and the tip lid surface 120 of the lid 100 is internally fitted into the tip opening 260. It is designed to prevent liquid leakage.

Further, a pressing portion 270 is formed on the flange portion 250 on the rear side of the tip opening portion 260. The pressing portion 270 is formed on the flange portions 250 on both sides, and is arranged so as to face each other. Further, as will be described later, the pressing portions 270 on both sides are portions that are sandwiched and pressed by the fingers of one hand (for example, the thumb and the index finger), and are curved inward so as to be easily pressed.

The lid 100 and the container body 200 according to the present embodiment are sheet-like materials having a thickness of about 0.1 to 1.0 mm that can be sheet-molded (for example, vacuum-molded, pressure-pneumatic molding, hot plate-molding). For example, as the material of the lid 100, A-PET, transparent biaxially stretched polystyrene (center OPS), or transparent biaxially stretched polystyrene (central OPS) is used so as to ensure visibility of the contents and have appropriate elasticity. As the material of the container body 200, polypropylene (PP) can be used, and A-PET, polypropylene containing filler (PPF), or polystyrene (PS) can be used. The lid body 100 and the container body 200 are polygonal in a plan view, but can be appropriately changed to any shape such as a substantially circular shape in a plan view.

Next, the inner fitting container 300 in a state where the lid 100 shown in FIG. 1 is covered with the container body 200 shown in FIG. 2 will be described with reference to FIG.

As shown in FIG. 3, in the inner fitting container 300, the lid side fitting portion 140 of the lid body 100 is internally fitted into the container side fitting portion 240 of the container body 200 and sealed over the entire circumference, and the container body is sealed. Prevents liquid leakage from the contents inside the 200.

Further, as shown in FIG. 3C, on the tip lid surface portion 120 side of the lid body 100, the bottom surface 141 of the lid side fitting portion 140 is floated from the bottom surface 241 of the container side fitting portion 240, and the lid side. The fitting portion 140 is internally fitted to the container-side fitting portion 240. This is because, as will be described later, the lid-side fitting portion 140 on the tip lid surface portion 120 side is easily disengaged from the container-side fitting portion 240, making it easier to open the tip lid surface portion 120. On the tip lid surface portion 120 side of the lid body 100, the bottom surface 141 of the lid side fitting portion 140 is in a state of floating from the bottom surface 241 of the container side fitting portion 240, but the bottom surface 141 is not limited to this. The lid side fitting portion 140 may be internally fitted to the container side fitting portion 240 in a state where the lid side fitting portion 140 is in close contact with the bottom surface 241. Further, in the portion other than the tip lid surface portion 120 of the lid body 100, the lid side fitting portion 140 is fitted on the container side while the bottom surface 141 of the lid side fitting portion 140 is in close contact with the bottom surface 241 of the container side fitting portion 240. The lid side fitting portion 140 may be internally fitted to the container side fitting portion 240 while the bottom surface 141 may be floated from the bottom surface 241.

Next, how to open the lid 100 will be described with reference to FIG.

First, as shown in FIG. 4A, the user presses the pressing portions 270 on both sides of the container body 200 inward with two fingers of one hand, for example, the thumb F1 and the index finger F2. Then, as shown in FIG. 4B, the tip opening 260 located in front of the pressing portion 270 is deformed so as to become thinner toward the front end side 201. Along with the deformation of the tip opening 260, the container-side fitting portion 240 formed along the tip opening 260 is also deformed so as to become thinner toward the front end side 201.

Then, the tip opening 260 and the container-side fitting portion 240 are deformed in a substantially V shape toward the front end side 201, so that the lid-side fitting portion 140 facing the deformed container-side fitting portion 240 is formed. A gap Y (indicated by a diagonal line in the drawing) is formed between the two, and the portion where the gap Y is generated is gradually disengaged. At the same time, the tip lid surface portion 120 is pushed upward by the tip opening portion 260 and the container-side fitting portion 240 that are deformed so as to be narrowly squeezed into a substantially V shape. As a result, the lid-side fitting portion 140 of the tip lid surface portion 120 is disengaged from the container-side fitting portion 240, and the tip lid surface portion 120 is opened so as to rise upward.

Then, as shown in FIG. 5, when the tip lid surface portion 120 is opened so as to rise upward, a discharge port Z is formed between the tip lid surface portion 120 and the tip opening portion 260. Then, in that state, by tilting the inner fitting container 300 toward the front end side 201, the contents in the container body 200 can be discharged to the outside from the discharge port Z. Alternatively, the open tip lid surface portion 120 may be pinched with a finger to completely peel off the lid body 100.

In FIGS. 4 and 5, the tip opening 260 and the container-side fitting portion 240 are greatly deformed for convenience of explanation, but in reality, the container side of the lid-side fitting portion 140 is formed. A slight deformation to the extent that the inner fitting to the fitting portion 240 is disengaged is sufficient.

As described above, according to the inner fitting container 300 of the present invention, the lid side fitting portion 140 of the lid body 100 is internally fitted to the container side fitting portion 240 of the container body 200 over the entire circumference. , It is possible to suppress the contents of the container body 200 from leaking. Further, when opening the lid 100, the pressing portion 270 of the flange portion 250 of the container main body 200 is pressed, and the tip opening 260 of the container main body 200 and the container side fitting portion 240 become thinner toward the front end side 201. The inner fitting on the tip lid surface portion 120 side is easily disengaged, the tip lid surface portion 120 floats upward and opens, and the discharge port Z is formed between the tip lid surface portion 120 and the tip opening 260. It is formed. In particular, when opening the lid 100, it is only necessary to locally deform the tip opening 260 of the container body 200 and the container-side fitting portion 240 via the pressing portion 270. Therefore, as in the conventional case, the container It is possible to prevent the main body from being greatly deformed and the contents from being scattered. Further, when opening the lid body 100, only the pressing portion 270 of the container body 200 is locally pressed, so that no extra force is applied as compared with the conventional method of greatly deforming the lid body 100, and the lid body can be opened. It is possible to prevent the contents from scattering due to the reaction when opened. Therefore, according to the present invention, the lid 100 can be opened with a light force while preventing liquid leakage, and the contents of the container body 200 can be prevented from scattering.

Further, as shown in FIG. 4, the pressing portion 270 is provided behind the tip opening 260, and is arranged at a position away from the tip 261 of the tip opening 260. Therefore, even if the force for pinching the pinching portion 270 is small, the force for deforming the tip 261 of the tip opening 260 so as to be thin (in other words, the moment around the tip 261) is large. Therefore, simply by lightly pressing the pressing portion 270, the lid-side fitting portion 140 of the tip lid surface portion 120 is disengaged from the container-side fitting portion 240, and the tip lid surface portion 120 opens so as to rise upward.

Further, since the tip 121 of the tip lid surface portion 120 of the lid body 100 is formed at an blunt angle, the tip is formed when the tip opening 260 and the container-side fitting portion 240 are deformed so as to become thinner toward the front end side 201. The tip opening 260 of the lid surface portion 120 is shallowly hooked, and the inner fitting portion 140 of the lid side fitting portion 140 of the lid body 100 and the container side fitting portion 240 of the container body 200 are easily disengaged. As a result, the lid-side fitting portion 140 of the tip lid surface portion 120 is easily disengaged from the container-side fitting portion 240 and the tip lid surface portion 120 is opened so as to rise upward by simply pressing the pressing portion 270 lightly. ..

Further, the pressing portion 270 is provided on the container body 200 side, and when the lid 100 is opened, the container body 200 is locally deformed via the pressing portion 270 to fit the lid 100 on the lid side. The inner fitting between the portion 140 and the container-side fitting portion 240 of the container body 200 is removed. Then, when the pinching pressure on the pressing portion 270 is released by releasing the finger, the container body 200 that has been elastically deformed returns to the original shape before the deformation. On the other hand, since the lid body 100 is not elastically deformed by the pinching pressure, the lid body 100 can be maintained in an open state even if the pinching pressure is removed. Therefore, even if the pinching pressure is eliminated, the contents can be discharged from the discharge port of the open lid 100 or the lid 100 can be completely removed, which is convenient.

Further, as shown in FIG. 3C, on the tip lid surface portion 120 side of the lid body 100, the bottom surface 141 of the lid side fitting portion 140 is floated from the bottom surface 241 of the container side fitting portion 240, and the lid side. Since the fitting portion 140 was internally fitted to the container-side fitting portion 240, when the tip opening 260 and the container-side fitting portion 240 were deformed to be thin, the tip lid surface portion 120 was fitted to the lid side. The portion 140 can be easily and quickly disengaged from the container-side fitting portion 240. As a result, the lid-side fitting portion 140 of the tip lid surface portion 120 is easily disengaged from the container-side fitting portion 240 and the tip lid surface portion 120 is opened so as to rise upward by simply pressing the pressing portion 270 lightly. ..

Further, when the pressing portion 270 of the container body 200 is pressed inward, the tip 121 side of the tip lid surface portion 120 of the lid body 100 is lifted upward, and the rear end 125 side is deformed so as to be recessed downward. 120 can be opened greatly upward. As a result, even if the pressure is applied with a light force, the tip lid surface portion 120 opens wide and the lid body 100 can be easily opened.

Further, since the lid body 100 is provided with a rib 160 or a step 160A extending in the direction of pressing the pressing portion 270, the tip lid surface portion 120 can be easily opened widely in the upward direction with the rib 160 or the step 160A as an opening / closing axis. There is. Further, since the rib 160 or the step 160A extends in the direction of sandwiching the pressing portion 270, the lid 100 is less likely to be deformed in the direction of sandwiching the pressing portion 270, and the rigidity is increased. Therefore, by increasing the rigidity of the tip lid surface portion 120 of the lid body 100, the tip lid surface portion 120 is pushed out to the tip opening 260 which is thinly deformed at the time of pinching, and is easily opened so as to be flipped upward. It is. Similarly, since the tip lid surface portion 120 has a substantially polygonal shape in a plan view, it is difficult to be deformed by an external force from the side, and the rigidity is increased. Therefore, the tip lid surface portion 120 is pushed out by the tip opening 260 which is thinly deformed at the time of pinching, and is easily opened so as to be flipped upward.

In the present embodiment, the lid-side fitting portion 140 is convex and the container-side fitting portion 240 is concave, but the present invention is not limited to this, and the lid-side fitting portion 140 is concave and the lid-side fitting portion is concave. 140 may be convex.

Further, the inner fitting container of the present invention is not limited to the above-described embodiment, and various modifications and combinations are possible within the scope of claims and embodiments, and these modifications can be made. Examples and combinations are also included in the scope of rights.
