Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container main body or a lid which escapes fermentation gas generated from a container or expansion gas generated by heating in a microwave oven without leaking liquid components in the container. The present invention relates to a container mainly for storing food, which prevents expansion and damage of the food.

[0002]

2. Description of the Related Art For example, in a container containing fermented products such as kimchi and pickles, after the container is sealed, fermentation continues inside the container,
Generate gas. As the fermentation progresses, the gas fills the container to inflate the lid or the container body, and in some cases, may explode. In order to solve this problem, a gas vent hole may be provided in the container body or the lid. However, the liquid content is contained in the container. Leaks out. Further, in the case of sealed foods for microwave cooking, if the heating or heating time by the microwave oven is too long, a similar situation occurs, such as the explosion of steam in the container due to expansion.

In order to prevent the lid from being damaged due to gas expansion of the fermented food A, in a conventional container, for example, as shown in FIG. It is stuck. However, in such a container, the adsorbent B must be fixed to the back surface of the lid C before the lid C is sealed by heat welding or the like to the opening end surface or the flange portion of the container body D. Since the work of attaching the adsorbent B is usually performed manually, the production efficiency is low. Further, the use of the adsorbent B increases the production cost. No specific measures have been taken to avoid accidents due to internal gas inflation in containers containing microwave cooked food.

[0004] It is an object of the present invention to provide a container which allows only gas in a sealed container body to escape to the outside of the container body without causing leakage, thereby preventing various inconveniences caused by gas swelling.

[0005]

The present invention has the following arrangement to achieve the above object. That is, the container of the present invention includes a container body and a lid covering the opening thereof.
The liquid or contents inside the container body is unlikely to leak to the outside of the sealed part between the container body and the lid, and the pressure gas such as the gas generated in the container body or the expanding gas due to heating of the microwave oven can leak. Fluid passage is provided.

The fluid passage includes a sealing portion between the container body and the lid,
That is, it is provided at a sealing portion between the opening end surface (including the flange portion) of the container body and the peripheral portion of the lid. The sealing portion is a portion where the container main body and the lid are sealed, and includes a case where an intermediate member is interposed between the container main body and the lid. When an intermediate member is interposed, a fluid passage described later is provided therein.
As for the fluid passage of the intermediate member, the configuration described later is applied to the portion on the container body side and the portion on the lid body side. Sealing includes heat welding, gluing, or other securing or stopping means. The sealing means is appropriately selected depending on the materials of the lid and the container body.
The lid has a sealing portion formed of a sheet material such as a plastic film sheet or other flexible material, and the surface is subjected to appropriate printing or the like as necessary. If the sealing means cannot be peeled off, the lid is opened by cutting it off with an appropriate instrument. Note that the entire lid does not need to be formed of a flexible material, and may have a thickness or height.

The following means is used for forming the fluid passage. On the opening end surface of the container body in which the lid is sealed, a plurality of annular sealing surfaces are formed at intervals in the radial direction along the opening, and between the sealing surfaces, above the sealing surface. The projecting support surface is likewise annularly formed.
The peripheral portion of the lid covering the opening end surface is brought into close contact with the upper end of the support surface portion and is sealed to the sealing surface portion so that voids are formed on both the inner and outer sides of the support surface portion. The lid peripheral edge portion is fixed to the sealing surface portion, and does not adhere to the support surface portion, but only comes into close contact. Each of the sealing surfaces is formed with a communication path that traverses the sealing surface and communicates the inside of the container body or the outside of the container body with the gap. The fluid passage formed by the communication passage and the gap forms an internal cutoff passage that seals a liquid or a container in the container body at a contact portion between the support surface portion and the lid peripheral portion. On the other hand, for a pressure gas such as a gas or an inflating gas generated in the container body, the close contact portion is forcibly separated and passed therethrough, thereby passing a series of fluid passages from the inside to the outside of the container body. Make.

[0008] The opening end face of the container body to which the lid peripheral edge is sealed is the upper end face of the container body when the thickness of the container body is large, and from the opening end of the container body when the thickness of the container body is relatively thin. It is an upper surface of a flange portion formed to protrude outward. The sealing surface portion is a portion where the peripheral edge portion of the lid is sealed at the opening end surface, and forms an annular shape along the opening. At least two sealing surfaces are provided at intervals in the radial direction (width direction) of the opening end surface. The way of sealing to the sealing surface is not limited to any fixing means such as heat welding and bonding.

The support surface provided between the sealing surfaces protrudes above the sealing surface. The support surface is formed, for example, in a trapezoidal cross section. The upper end surface of the support surface and the peripheral edge of the lid are kept in close contact with each other without being sealed as described above. Since the support surface protrudes above the sealing surface, a gap is formed between the peripheral portion of the lid that covers the opening end surface and both sides of the support surface. When no retention groove is formed between both sides of the support surface and the sealing surface, the void serves as a liquid retention space and a gas passage. Therefore, it is desirable to set the degree of protrusion of the support surface portion to be larger when there is no stagnation groove than when it is present. In addition, the contact portion
The material of the lid may be provided with an intermittent fixing portion according to the size of the container.

An annular retaining groove is preferably formed between the sealing surface and the supporting surface, particularly between the innermost sealing surface and the supporting surface adjacent thereto. Of course, an annular retaining groove may be formed between the support surface portion and the sealing portion. For example, when two sealing surface portions are provided on the opening end surface of the container body and one supporting surface portion is formed between the sealing surface portions on the opening end surface of the container body, between the inner mounting surface portion and the supporting surface portion, and outside. An inner retaining groove and an outer retaining groove are respectively formed between the mounting surface portion and the supporting surface portion of the first member.

A communication passage communicating with the gap is provided in the sealing surface. The communication passage is generally formed as a groove on the surface. When the retaining groove is formed, the communication passage may be formed to penetrate the wall surface of the sealing surface portion.
The positional relationship and the number of the communication passages respectively formed in the plurality of mounting surface portions are not particularly limited, but are desirably provided at the counter electrodes in the circumferential direction.

The fluid passage formed by the communication passage and the gap is formed by a pressure contact between the upper end of the support surface and the peripheral portion of the lid against pressure gas such as fermentation gas or heated gas. From forming a fluid passage of
The degree of close contact between the upper end of the support surface and the peripheral edge of the lid is set in consideration of this.

According to a seventh aspect of the present invention, the present invention is applied to a container in which a container body and a lid are detachable, wherein the lid has a ring body having an annular inner groove and an outer groove on a lower surface. And a flexible sheet member that fills the space inside the ring of the ring member. A female screw is formed in the outer groove of the ring body, and the inner groove has a groove opening covered by the peripheral edge of the sheet body. On the other hand, the container body has an annular outer rib having an external thread that is screwed with a female screw in the outer groove of the lid, on the opening end face where the lid is sealed,
And an inner rib that enters the inner groove of the lid. The sheet body is
For example, the end of the peripheral portion is inserted into the outer groove and fixed thereto, thereby being integrated with the container body. When the container body and the cover are screwed with the outer rib and the outer groove to cover the container body with the cover, the lower surface of the peripheral edge of the sheet body covering the groove opening of the groove in the ring and the opening end surface of the container body. Between the inner body of the container body and the inner groove part of which is separated by a contact part in which the upper end of the inner rib of the container body is in close contact with the lower surface of the peripheral edge of the sheet body, the outer groove of the ring body, and the container. Between the outer rib of the body,
An outer gap portion that can communicate with the outside of the container body and the inner gap portion is formed. Then, while the liquid or the contents in the container body is prevented from passing through the gap by the close contact portion, the close contact portion is forcibly separated from the pressure gas generated in the container main body, and the container From the inside of the main body to the outside, a series of fluid passages are formed in which the inner and outer gaps communicate.

An eighth aspect of the present invention relates to a container similar to the seventh aspect. In the present invention, when the container body and the lid are screwed together with the outer rib and the outer groove and the container body is detachably covered with the lid, the peripheral edge of the sheet body covering the groove opening of the groove in the ring is formed. The lower surface is pressed against the opening end surface of the container body. The support portion at the upper end of the inner rib of the container body pressed into the groove in the ring body forms voids on both the inside and outside of the close contact portion between the support portion and the peripheral portion of the sheet body. Further, an outer gap portion that can communicate with the outside of the container body is formed between the outer groove of the ring body and the outer rib of the container body. Further, on the opening end face of the container body, an inner communication path communicating with the inside of the container body and the inner gap, and an outer communication path communicating with the outside of the container body and the outer gap and the outer gap are provided. It is formed. The above-mentioned close contact portion prevents the liquid or the contents in the container main body from passing outside the container main body while the close contact portion is forcibly separated from the pressure gas generated in the container main body. Thus, a series of fluid passages are formed from the inside of the container body to the outside, in which the inner communication passage, the inner and outer clearances, the outer clearance, and the outer communication passage communicate with each other.

The communication passage employed in the present invention has an outer end formed to have a diameter smaller than that of the inner end, or a bottom surface facing outward, in order to prevent liquid leakage and enable gas release. It is good to form it uphill.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on illustrated embodiments. FIG. 1 is a perspective view showing a state in which a lid of a container according to an embodiment of the present invention is being removed, FIG. 2 is a longitudinal sectional view of the container, FIG. 3 is a plan view of the container main body, and FIG. It is an expanded sectional view of a part.

In the figure, reference numeral 1 denotes a container body molded from a synthetic resin material, and has an annular flange portion 2 extending horizontally at an opening end. The opening 3 and the flange portion 2 of the container body 1 are covered by a lid 4 formed of a sheet material. The lid 4 is formed of a synthetic resin film sheet, and the peripheral portion 41 is formed of the flange portion 2 of the container body 1.
Is thermally welded so as to be peelable. On the surface of the lid 4, characters, designs, and the like are printed on the outer peripheral edge including the peripheral portion 41, which is a sealing portion with the container body 1, on the surface.

The flange portion 2 of the container body 1 is provided with two sealing surfaces 21 and 22 at a required interval at an inner position and an outer position in a radial direction. The sealing surface portions 21 and 22 are formed along the opening 3 in an annular shape, and are portions where the peripheral portion 41 of the lid 4 is thermally welded. Between the sealing surface portions 21 and 22, a support surface portion 23 projecting slightly upward from the sealing surface portions 21 and 22 is annularly projected. On both sides of the support surface 23, annular retaining grooves 24 and 25 are formed. Support surface 2
No. 3 is simply in a close contact state without being thermally welded to the lid peripheral edge portion 41 in contact. The contact state is determined by the sealing surface portion 21,
When welding the lid peripheral edge 41 to the lid 22, the lid peripheral edge 41
This is achieved by maintaining a slight tension in the portion between the inner and outer welding positions in the above. In the contact portion 8,
If necessary, it is also possible to provide heat-welded fixing portions at appropriate intervals. The fixing portion is of such a size that it can be automatically peeled off by the pressure of the fermentation gas generated from inside the container body. Since the support surface portion 23 is located above the sealing surface portions 21 and 22, the retaining grooves 24 and 25 on both sides of the support surface portion.
Are formed above the space.

Inner sealing surface 21 and outer sealing surface 22
, Communication passages 6 and 7 are recessed at appropriate positions in the circumferential direction on the surface. In FIG. 3, communication paths 6 and 7 are provided at the 6 o'clock position on the inner sealing surface portion 21 and at 12 o'clock position on the outer sealing surface portion 22, respectively. The inner communication passage 6 has an inner end opening into the inner space of the container body and an outer end opening into the inner space 9. The outer communication path 7 has an inner end opening to the outer space 10 and an outer end opening to the outer space.

The operation of the container will be described with reference to FIGS. 6 and 7. When the liquid contained in the container in the container body enters the gap 9 from the inner communication passage 6 due to the inclination of the container or the like, the liquid accumulates in the inner retaining groove 24 (FIG. 6). The amount of liquid in the groove is small due to the small volume of the groove. For this reason, even if the container is tilted again, the force of separating the close contact portion 8 between the support surface portion 23 and the lid peripheral edge portion 41 does not reach depending on the liquid pressure. Therefore, the inner gap 9 and the outer gap 10 do not communicate with each other, and the inner communication path 6 and the gap 9 are disconnected from the outer communication path 7 and the gap 10 at the close contact portion 8. Keep it done. Inner retention groove 2
4 accumulates on the lid peripheral edge 41 covering the flange 2.
It is hidden by the printing on the surface, so it is not visible from the outside.

On the other hand, fermentation gas or inflation gas generated from the stored material similarly enters the inner gap 9 from the inner communication passage 6. The gas that has entered the inner space 9 pushes the lid peripheral edge 41 around the contact portion 8 upward by its own pressure, and separates the lid peripheral edge 41 from the upper end of the support surface. For this reason, the gas passes through the contact portion 8 and escapes to the outer gap portion 10, passes through the outer gap portion 10 and the outer retaining groove 25, and
It is discharged to the external space via the outer communication path 7 located in the opposite direction by 180 degrees (see FIG. 7).

Experimental Example A flat circular outer diameter of 96 mm, a height of 45 mm, and a wall thickness of 10 mm
Two 2 mm-wide sealing surfaces on the open end face of the container body
Two retaining grooves having a width of 2 mm were provided, and a supporting surface portion also having a width of 2 mm was formed at the center in the width direction of the opening end surface by 0.5 mm (h in FIG. 4) above the sealing surface portion. In addition, two communication passages having a width of 1 mm and a depth of 0.1 mm were formed at the same positions of the sealing surface as in the above embodiment. 100 g of Chinese cabbage kimchi was stored in the container body, and the opening was made of a PET film (thickness: 0.05).
mm), and the peripheral edge was thermally welded to the sealing surface.

This sample was observed to be left at room temperature for 3 days. Even after 3 days, no deformation such as expansion of the lid or the container body was observed, and it was found that the fermentation gas was effectively discharged out of the container body. During the observation period and after the observation period (3 days), when the container was turned upside down, the liquid inside penetrated into the gap from the inner communication passage, but the contact portion between the support surface and the peripheral edge of the lid was separated. It did not flow into the outer void. As a result, it has been found that the present invention effectively prevents liquid leakage and vents gas.

In the present embodiment, the sealing surface of the container must be provided at least at two places, inside and outside. If the opening end surface to which the lid peripheral edge is sealed is large, one or more additional openings may be provided in the middle. In this case, a support surface portion is provided between the intermediate sealing surface portion and the inner and outer sealing surface portions, respectively, and an intermediate communication path is formed in the intermediate sealing surface portion. Although the retaining groove is not necessarily required in the container of the present embodiment, at least the inner retaining groove is required in order to effectively retain the liquid in consideration of an emergency.

FIG. 8 is a plan view of a container main body according to another embodiment of the present invention, and FIG. 9 is an enlarged view showing a main part of the container. In both figures, the same members as those of the first embodiment are denoted by the same reference numerals in the hundreds. In this embodiment, no stagnation groove is formed between the sealing surfaces 121 and 122 and the support surface 123. Instead, the support surface 123
The distance is set between the sealing surface portions 121 and 122 and the support surface portion 123 so that the above-mentioned gap portions 109 and 110 are formed on both the inside and outside of the device.

The pressurized gas such as fermentation gas generated inside the container body 101 enters the gap through the inner communication passage 106,
Here, the contact portion 108 at the peripheral edge of the lid is slightly pushed up to pass through the support surface portion 123, and escapes from the outer communication passage 107 to the outside of the container body through the outer space 110 (see FIG. 8). Even if the internal liquid enters the inner communication passage 106, it does not push up the contact portion 108, so that the support surface 12
3 does not leak outside. Also, even if the support surface 123 can be overcome, the outer space 11
Since it has to go through 0 through 180 degrees and enter the outside communication passage, it hardly goes out of the container body. The container according to the present embodiment is desirably used as a container for storing contents having relatively low water content.

FIGS. 10 to 12 show still another embodiment of the present invention. 10 is a cross-sectional view showing a main part of a container to which the present invention is applied, FIG. 11 is a cross-sectional view showing a main part of a lid used for the same, and FIG. 12 is an enlarged cross-sectional view of a part of FIG. . In the figure, the same reference numerals as in the first embodiment denote the same or corresponding members in the 200s.

In this embodiment, a container is provided in which the lid body 204 in which the ring body 241 and the sheet body 245 are integrated is detachably attached to the container body 201. The ring body 241 is formed of a synthetic resin material, and has an annular inner groove 244 and an outer groove 242 deeper than the inner groove 244 on the lower surface. A female screw 243 is formed in the outer groove 242. The sheet body 245 is formed of a synthetic resin film sheet material having a slight elasticity, and is stretched over the inner space of the ring body 241. The peripheral edge 245a of the sheet body 245 covers the groove opening of the inner groove 244 so as to cover the groove opening, and the end is fixed to the inner wall of the outer groove.

The container main body 201 has an annular outer rib having an external thread 227 screwed to the female screw 243 in the outer groove of the lid 204 on the opening end face 202 (flange portion) where the lid 204 is sealed. 226 and an inner rib 223 that enters the inner groove 244 of the lid 204. Outer rib 226 and outer groove 24
No. 2 has a gap 206 (206C) that allows the passage of the pressure gas when the screws 227 and 243 are screwed together. The inner rib 223 has a chevron shape in cross section, and has an inner groove 244.
When it enters, it comes into close contact with the corresponding portion of the sheet body peripheral edge 245a, and pushes up this to push up the sheet body peripheral edge 245a.
Are positioned in the inner groove, and voids 209 and 210 through which a pressurized gas can pass are formed on both the inner and outer sides. Similarly, when the lid 204 is covered with the container body 201, a gap 206 (206A, 206B) through which a pressurized gas can pass is similarly provided between the lower surface of the peripheral portion of the sheet body and the opening end face 102 of the container body 201. ) Is formed.

Therefore, the lid 204 is attached to the container body 201.
When the container is attached, the container has inner gap portions 206A and 206B between the lower surface of the sheet body peripheral portion 245a and the open end surface 202 of the container body 201, and the outer groove 242 of the ring body 241 and the outside of the container body 201. An outer clearance 206C through which the pressure gas can pass is provided between the rib 226 and the rib 226. Then, at the location of the inner groove 244 of the lid 204, the container body 201
Inner peripheral rib 245 whose inner rib upper end covers inner groove 244
At the same time, a close contact portion 208 is formed to closely close to the lower surface of a and push it into the inner groove, and at the same time, block off the inner gap portions 206A and 206B.

For this reason, the liquid contained in the container body 201 penetrates into the innermost inner gap portion 206A generated between the lower surface of the peripheral portion of the sheet main body and the opening end surface, but enters the contact portion 208 in the inner groove. Blocked, preventing further leakage. On the other hand, the fermentation gas and the expansion gas due to the heating are supplied from the inner gap 206A and the inner gap 209 to the close contact portion 208A.
The sheet body peripheral edge portion 245a is pushed up, gets over the upper end of the inner rib, and enters the outer gap 206B between the sheet body peripheral edge lower surface and the opening end surface. From here, the outer groove 2
It is guided to the outside of the container body through a gap 206C between the outer rib 42 and the outer rib 226.

As a modification of the embodiment shown in FIGS. 10 to 12, the lower surface of the peripheral portion of the sheet body is pressed against the opening end surface of the container body without forming an inner gap portion, and the inner and outer inner portions are sealed. An inner communication passage similar to that shown in the first embodiment may be formed in the gap. Naturally, these communication passages communicate with gaps formed on both sides of the support portion of the inner rib. Further, an outer communication passage communicating with the outer clearance is also formed on the opening end face outside the outer rib. According to this modification, the hermeticity of the sealing portion between the lid and the container body can be further improved.

In any of the embodiments including the first embodiment, the communication path may be formed such that the outer end is smaller in diameter than the inner end in plan view, as shown in FIG. 13A, for example.
In addition, the communication passage may have a bottom surface that is inclined upward toward the outside. In any case, the liquid or the like in the container body is less likely to leak to the outside. In the embodiment of FIGS. 10 to 12 and its modified embodiments, the communication path may extend obliquely in a direction that is compatible with the direction of tightening the screws of the lid and the container body. FIG. 13B schematically shows a cross section of the communication path for a screw that closes clockwise.

The container of the embodiment shown in FIGS. 10 to 12 can be used repeatedly as long as the flexibility of the sheet body is not impaired, and can be used for a container having a relatively large diameter. In addition, liquid leakage can be prevented by a part of the constituent members of the lid without using packing. The cross-sectional shape of the inner rib, the fixing position of the peripheral edge portion of the sheet member, and the shape and direction of the screw of the outer rib are not limited as long as the above-described action is exerted.

[0065]

According to the first aspect of the present invention, the container body is provided with a plurality of annular sealing surfaces for sealing the peripheral portion of the lid, and projects upward from the sealing surface between the sealing surfaces. Since the annular support surface portion is provided, and the contact portion between the upper end of the annular support surface portion and the peripheral portion of the lid body is only brought into close contact,
The fluid passage formed by the communication passage provided on the sealing surface and the gap on both sides of the support body prevents the liquid from flowing out at the close contact portion, while slightly separating the close contact portion against the pressurized gas. Pressure gas, such as fermentation gas generated in the container body or inflation gas generated by heating the microwave oven, can be effectively released to the outside of the container body without causing liquid leakage. Can prevent the container body and the lid from being damaged. Further, since a part of the opening end surface of the container body is used as the sealing surface of the lid, the lid can be easily released as compared with the case where the entire opening end surface is used as the sealing surface. According to the seventh and eighth aspects of the present invention, similarly, not only can the pressure gas escape to the outside of the container body without causing liquid leakage, but also the sheet constituting the lid can serve as the packing material. In addition, a container that can be used repeatedly can be provided.
