Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a container, and more particularly, to a container having a container main body having an opening and a lid for closing the opening, the container having high liquid tightness when the lid is closed.
[0002]
[Prior art]
Containers including a container body having an opening and a lid for closing the opening are frequently used in various fields. FIG. 1 is a plan view of such a container (container having a container main body having an opening and a lid for closing the opening) 101 which is conventionally used, and FIG. 2 is an AA end view of FIG. FIG. 3 is an enlarged view of a circle B in FIG. 2, and FIG. 4 is an end view showing a state where the container body 103 and the lid 105 are removed from the state of FIG. 2 and 4, the end faces are shown by lines, but of course, they have a thickness.) With reference to FIGS. 1 to 4, a container 101 that has been used conventionally will be described.
[0003]
The container 101 includes a container body 103 having an opening 103a, and a lid 105 closing the opening 103a. The container body 103 has a fitting ridge 103b which is a ridge protruding toward the lid 105 and surrounding the opening 103a, and the lid 105 has a fitting concave groove 105b for fitting the fitting ridge 103b. Have. The container main body 103 has a main body joining surface 103c (a surface facing the lid 105 among both surfaces of the fitting protrusion 103b) which is a surface formed so as to surround the opening 103a. The lid 105 has a lid bonding surface 105c (a surface facing the container main body 103 among both surfaces of the fitting concave groove 105b) which is a surface bonded to the main body bonding surface 103c. Here, the main body joint surface 103c and the lid joint surface 105c are formed so as to surround the entire periphery of the opening 103a (refer to FIG. 2 and FIG. 4 in particular).
[0004]
Both the container body 103 and the lid 105 constituting the container 101 are formed of a transparent and thin synthetic resin, and the fitting protrusions 103b are fitted into the fitting concave grooves 105b as shown in FIGS. The container main body 103 and the lid 105 are fixed to each other, and the main body joining surface 103c and the lid joining surface 105c are joined (here, both surfaces 103c and 105c are substantially close to each other. In particular, see FIG. 3). By doing so, the inside 101a of the container can be substantially sealed.
[Problems to be solved by the invention]
However, when a container (for example, pickles such as kimchi) containing a liquid such as water is stored in the container interior 101a of the conventional container 101 as described above, the liquid such as water contained in the container is stored. However, there is a problem in that the material leaks out from between the body joining surface 103c and the lid joining surface 105c. This is because the liquid such as water contained in the container adheres from the inside 101a of the container to the space between the main body joint surface 103c and the lid joint surface 105c (when the liquid such as water moves in the direction of arrow C in FIG. 3). This is because the liquid such as water seeps out through the space between the main body joint surface 103c and the lid joint surface 105c to the outside (the liquid seeps in the direction of arrow D in FIG. 3).
[0006]
Therefore, in the present invention, a container that substantially seals the inside of the container by joining the main body joining surface and the lid joining surface, and a liquid such as water flows from the inside of the container between the main body joining surface and the lid joining surface. It is an object of the present invention to provide a container that prevents or reduces the amount of water flowing out to the outside.
[0007]
[Means for Solving the Problems]
The present inventor has investigated the cause of liquid such as water passing through between the main body joint surface and the lid joint surface and oozing out to solve the above-described problem. It was clarified that it was due to the capillary phenomenon occurring in the gap between the two. In view of this elucidation result, the present inventor has invented the container of the present invention (hereinafter, referred to as “the present container”).
That is, the present container is a container including a container main body having an opening, and a lid for closing the opening, wherein the container main body has a main body joining surface that is a surface formed so as to surround the opening. The lid has a lid joining surface that is a surface that is joined to the main body joining surface, and one of the main body joining surface and the lid joining surface is joined to the main body joining surface and the lid joining surface. A container having a ridge formed integrally with said one along said one so as to protrude toward the other when it is made.
[0008]
In this way, one of the main body joining surface and the lid joining surface is directed toward the other (the other of the main body joining surface and the lid joining surface) when the main body joining surface and the lid joining surface are joined to each other. The main body joint surface and the lid joint surface are closely contacted with each other around the one ridge (one or both sides of the ridge) because the ridge has a ridge formed integrally with the one so as to protrude. (A predetermined gap is formed between the joint surface of the main body and the joint surface of the lid according to the height of the ridge), so that capillary action can be prevented or reduced around the ridge. Further, since the ridge has a strong contact with the other (the contact area is smaller than when there is no ridge), a liquid such as water passes through the contact portion between the ridge and the other. Can be made difficult. From these facts, the present container can prevent or reduce the liquid such as water from leaking outside through the space between the main body joint surface and the lid joint surface.
[0009]
When the main body joining surface and the lid joining surface are joined to each other, one of the container body and the lid is a ridge formed so as to project toward the other and surround the opening. And the other of the container body and the lid, which does not have the fitting ridge, has a fitting concave groove into which the fitting ridge is fitted (hereinafter, referred to as a “fit main container”). There may be.
In this way, the main body joint surface and the lid joint surface can be securely joined to each other at a predetermined position by fitting the insertion ridge into the engagement concave groove, so that any one of the main body joint surface and the lid joint surface can be used. The ridge formed on the one side can reliably contact the other side at a predetermined position, and a liquid such as water leaks to the outside through the space between the main body joint surface and the lid joint surface. This can be more reliably prevented or reduced.
[0010]
In the case of the fitted main container, the ridge may be formed on either the fitted ridge or the fitted concave groove (hereinafter, referred to as a "fitted part convex ridge-formed container").
By doing so, the fitting ridge is fitted into the fitting groove, so that it becomes difficult for liquid such as water to pass between the fitting ridge and the fitting groove, and the ridge reliably prevents the capillary phenomenon. (By forming a ridge on either the fitting ridge or the fitting groove for fixing the main body joint surface and the lid joint surface, even if the container is deformed or the like, the convex ridge will hit the other side. The position and direction of contact are difficult to change.), And it is possible to more reliably prevent or reduce liquid such as water from leaking outside through the space between the main body joint surface and the lid joint surface. Can be done.
[0011]
In the case of the present container, the fitting ridge is formed in a vertical section, which is a cross-section of the container by a vertical plane, when the fitting ridge is fitted in the fitting groove. It may be formed at the tip or at the deepest part of the fitting groove.
The “vertical cross-section, which is a cross-section of the container on a vertical plane” means that the container is placed in a state where the container is normally used on a horizontal surface (usually, the container body is at the bottom and the lid is at the top), A cross section that appears when cut along a vertical plane (a plane perpendicular to the horizontal plane).
By doing so, when the fitting ridge is fitted into the fitting concave groove, the ridge can reliably contact the other of the main body joining surface and the lid joining surface, and the liquid such as water It is possible to more reliably prevent or reduce leakage to the outside through the space between the joint surface and the lid joint surface.
[0012]
In the case of the fitting part convex ridge forming main container, when the fitting ridge is fitted in the fitting concave groove, the fitting ridge and the fitting concave groove are in contact with the inside of the convex ridge. Is also good.
In this case, “inside of the ridge” refers to a cross section cut across the ridge (a cross section perpendicular to the direction in which the ridge extends) and continues to the inside of the container on both sides of the ridge. One.
In this way, the fitting ridge and the fitting concave groove come into contact with each other on the inner side than the convex ridge, so that the liquid such as water contained inside the container comes into contact with the fitting ridge that has contacted each other before reaching the convex ridge. It is necessary to pass between the fitting concave groove, and since the momentum when arriving at the ridge is weakened, liquid such as water leaks outside through the space between the main body joining surface and the lid joining surface. This can be prevented or reduced more reliably.
[0013]
The body joining surface, the lid joining surface, and the ridge need not necessarily surround the entire periphery of the opening, but may be formed so as to surround the entire periphery of the opening. If formed so as to surround the entire periphery, it prevents liquid such as water from leaking outside through the space between the main body joint surface and the lid joint surface at all positions around the opening. Or it can be reduced.
[0014]
In a cross section crossing the ridge, the tip of the ridge may be formed by a curved surface.
Here, the “cross section crossing the ridge” refers to a cross section on a plane perpendicular to the direction in which the ridge extends (if the ridge extends along a curve, the tangential direction of the curve).
By doing so, the convex ridge abuts on the other of the main body joining surface and the lid joining surface as a curved surface, so that it is difficult to form a gap between the other and the tip of the convex ridge, and a liquid such as water Can be reliably prevented or reduced from leaking outside through the space between the main body joint surface and the lid joint surface. The curved surface may be of any shape, and may be, for example, a part of a circle or an ellipse.
[0015]
The height of the ridge may be any height as long as liquid such as water can be prevented from leaking to the outside through the space between the main body joint surface and the lid joint surface or reduced to a desired degree. Well, although not limited, it is usually preferably 0.07 mm or more, more preferably 0.085 mm or more, most preferably 0.1 mm or more, and preferably 0.16 mm or less, more preferably 0 mm or less. .145 mm or less, most preferably 0.13 mm or less (for example, usually preferably 0.07 mm or more and 0.16 mm or less, more preferably 0.085 mm or more and 0.145 mm or less, and most preferably 0.1 mm or less) Not less than 0.13 mm).
[0016]
The width of the ridge may be any as long as liquid such as water can be prevented from leaking to the outside through the space between the main body joint surface and the lid joint surface or reduced to a desired degree. Although not particularly limited, it is usually preferably 0.5 mm or more, more preferably 0.7 mm or more, most preferably 0.9 mm or more, and preferably 1.5 mm or less, more preferably 1. 3 mm or less, most preferably 1.1 mm or less (for example, usually preferably 0.5 mm or more and 1.5 mm or less, more preferably 0.7 mm or more and 0.3 mm or less, most preferably 0.9 mm or more 1.1 mm or less.)
[0017]
Further, the number of the ridges is not limited at all, and the number may be determined as needed, such as 1, 2, 3, 4,...
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited by these.
[0019]
FIG. 5 is a plan view of the container (main container) 11 of the present invention of one embodiment, FIG. 6 is an FF end view of FIG. 1, and FIG. 7 is an enlarged view in a circle G of FIG. FIG. 8 is an end view showing the container body 13 and the lid 15 removed from the state of FIG. 6, and FIG. 9 is a view of the lid 15 as viewed from below (in the direction of arrow K in FIG. 8). FIG. 10 is a view showing the container body 13 viewed from above (in the direction of arrow L in FIG. 8) (note that since both the container body and the lid are thin, FIG. 6). Also, in FIG. 8, the end faces are indicated by lines, but of course they have a thickness.) The container 11 will be described with reference to FIGS.
[0020]
The container 11 includes a container body 13 having an opening 13a, and a lid 15 for closing the opening 13a. The container body 13 has a fitting protrusion 13b which is a protrusion protruding toward the cover 15 and surrounding the opening 13a, and the cover 15 has a fitting groove 15b for fitting the fitting protrusion 13b. Have. The container main body 13 has a main body joining surface 13c (a surface facing the lid 15 among both surfaces of the fitting protrusion 13b) which is a surface formed so as to surround the opening 13a. The lid 15 has a lid bonding surface 15c (a surface facing the container body 13 among both surfaces of the fitting concave groove 15b) which is a surface bonded to the main body bonding surface 13c. Here, the main body joint surface 13c and the lid joint surface 15c are formed so as to surround the entire periphery of the opening 13a.
[0021]
Both the container body 13 and the lid 15 constituting the container 11 are formed of a transparent and thin synthetic resin (thin plate), and the fitting protrusions 13b are fitted into the fitting grooves 15b as shown in FIGS. By doing so, the container main body 13 and the lid 15 are fixed to each other, and the main body joint surface 13c and the lid joint surface 15c are joined, so that the inside 11a of the container can be substantially sealed.
On the other hand, the ridge 17 is formed in the fitting groove 15b along the fitting groove 15b so as to surround the entire periphery of the opening 13a. Here, the lid joining surface 15c has a ridge 17, and the ridge 17 is joined so that the lid joining surface 13c and the lid joining surface 15c project toward the main body joining surface 13c when they are joined to each other. It is formed integrally with the lid joining surface 15c along the surface 15c.
[0022]
The ridge 17 is the deepest of the fitting groove 15b in a vertical section (FIG. 7), which is a section of the container 11 by a vertical plane when the fitting ridge 13b is fitted in the fitting groove 15b. Part is formed.
When the fitting ridge 13b is fitted in the fitting groove 15b, the fitting ridge 13b is fitted on the inner side of the ridge 17 (the two sides of the ridge 17 that are continuous with the interior 11a of the container 11). The groove 15b is in contact with the groove 15b (in FIG. 7, the body joining surface 13c1 and the lid joining surface 15c1 inside the ridge 17 are in contact).
[0023]
FIG. 11 shows a cross-sectional view of the ridge 17 in a cross section that crosses the ridge 17 (a cross section perpendicular to the direction in which the ridge 17 extends. With reference to FIG. 11, the protrusion 17 will be described in detail.
Here, in a cross section (FIGS. 11 and 7) crossing the ridge 17, the tip 17a of the ridge 17 is formed by a curved surface (specifically, a part of a circle).
The height H of the ridge 17 is, here, 0.11 mm (0.9 mm or more and 1.1 mm or less).
The width W of the ridge 17 is 1 mm (0.9 mm or more and 1.1 mm or less). The shape of the tip 17 a of the ridge 17, the height H of the ridge 17, and the width W of the ridge 17 are the same in any cross section that crosses the ridge 17.
[0024]
As described above, the container 11 is a container including the container body 13 having the opening 13a and the lid 15 closing the opening 13a, and the container body 13 is formed so as to surround the opening 13a. The lid 15 has a lid joining surface 15c which is a surface joined to the main body joining surface 13c, and one of the main body joining surface 13c and the lid joining surface 15c (here, the lid The joining surface 15c) extends along the one (here, the lid joining surface 15c) so as to protrude toward the other (here, the main body joining surface 13c) when the main body joining surface 13c and the lid joining surface 15c are joined to each other. The container has a ridge 17 integrally formed with the one (here, the lid joining surface 15c).
[0025]
When the main body joint surface 13c and the lid joint surface 15c are joined to each other, one of the container main body 13 and the lid 15 (here, the container main body 13) and the other (here, the lid 15 ), And has an insertion ridge 13b which is a ridge formed so as to surround the opening 13a, and the other of the container body 13 and the lid 15 having no insertion ridge 13b (the lid 15 in this case). However, it has a fitting concave groove 15b for fitting the fitting protrusion 13b.
Further, the protruding ridge 17 is formed on either the fitting protrusion 13b or the fitting recess groove 15b (here, the fitting recess groove 15b).
[0026]
When the fitting ridge 13b is fitted in the fitting groove 15b, the convex ridge 17 is located at the tip of the fitting ridge 13b or the deepest portion of the fitting groove 15b in a vertical section which is a cross section of the container 11 by a vertical plane. (Here, formed at the deepest part of the fitting concave groove 15b).
When the fitting ridge 13b is fitted in the fitting groove 15b, the fitting ridge 13b and the fitting groove 15b are in contact with each other inside the ridge 17.
[0027]
Further, here, the main body joint surface 13c, the lid joint surface 15c, and the ridge 17 are formed so as to surround the entire periphery of the opening 13a.
Further, in a cross section crossing the ridge 17, the tip 17a of the ridge 17 is formed by a curved surface.
In addition, the height H of the ridge 17 is 0.11 mm (0.07 mm to 0.16 mm), and the width W of the ridge 17 is 1 mm (0.5 mm to 1.5 mm).
[0028]
If such a container 11 is used, the main body joint surface 13c and the lid joint surface 15c cannot be in close contact with each other around the ridge 17 (both sides of the ridge; see FIG. 7). A predetermined gap is formed between the main body joint surface 13c and the lid joint surface 15c according to the height of the ridge 17), so that the capillary phenomenon can be prevented or reduced around the ridge 17. Further, since the ridge 17 (tip portion 17a) comes into strong contact with the main body joint surface 13c, it is possible to make it difficult for a liquid such as water to pass through the contact portion between the ridge 17 and the main body joint surface 13c. From these facts, even if a substance containing a liquid such as water is stored in the interior 11a of the container 11, the liquid such as water seeps out through the space between the main body joint surface 13c and the lid joint surface 15c. Can be prevented or reduced. That is, in addition to the container body 13 and the lid 15 being freely attachable and detachable, when the lid 15 is attached to the container body 13, liquid such as water, This is extremely convenient because it can be prevented or reduced from seeping outside through the space between the surface 15c.
