In the package body (100), the contents (130) received in the container is sealed by adhering a resin film (120) to a first adhesion part (111) at the upper edge of the container (110). First projections (112) projecting into the container (110) and in contact with the lower surface of the resin film (120) are formed on a container wall. On the upper surfaces of the first projections (112) are provided through-holes (113) extending through the container wall, annular second adhesion parts (114) for weakly adhering portions surrounding the through-holes (113) to the lower surface of the resin film (120), and second projections (115) projecting to a level higher than the upper edges of the second adhesion parts (114).When the internal pressure of the container (110) is increased, the resin film (120) swells upward to peel off the second adhesion parts (114), causing gas in the container (110) to be discharged to the outside of the container (110) through the through-holes (113).
Description
Technical field
The present invention relates to the container that can be discharged to the packaging body of external container and be used for this packaging body from the gas that content produces.
Background technology
In order to prevent that foreign matter from sneaking into or quality descends, food such as box lunch and nonstaple food are mostly with the state sale of the packaging body that is sealed in resinous internal tank.In such food, commonly can under the state of packaging body, utilize micro-wave oven etc. to carry out the situation of cooking.But when under the state that food is sealed in internal tank food being heated, because the aqueous vapor that produces from food this moment, container might expand laterally and break.And, owing to the carrying out of fermented food concomitant fermentations such as pickles produces carbon dioxide, so even heating container not, container also might break.In view of this actual state, develop in recent years and can be discharged to exterior container from aqueous vapor or the carbon dioxide that content produces.
For example, in patent documentation 1, put down in writing a kind of automatic-cooking, it is characterized in that this automatic-cooking has with packing: the flexible container that has through hole at least at a place with packing; With with the bonding sheet pressure-modulation valve of the mode of sealing this through hole, become certain value when above at the internal pressure of flexible container, above-mentioned sheet pressure-modulation valve is opened.But, in the automatic-cooking usefulness of patent documentation 1 is packed,, need on flexible container, paste with flexible container and separate the flexible strip that forms for the sheet pressure-modulation valve is set.Therefore, the automatic-cooking of patent documentation 1 has the shortcoming that Fabrication procedure becomes complicated easily, manufacturing cost is high with packing.
And, in patent documentation 2, put down in writing a kind of packing container, this packing container lid is provided with through hole, on container body and lid, twine envelope and bring the above-mentioned through hole of sealing, when utilizing micro-wave oven etc. to heat, because the rising of internal pressure makes above-mentioned through hole envelope band on every side by last top.But therefore the packing container of patent documentation 2 has following shortcoming owing to need twine envelope band on container body and lid: manufacturing cost height not only, and must unload lower closure, the operation that breaks a seal correspondingly become loaded down with trivial details etc.
In addition, in patent documentation 3, put down in writing a kind of food of putting into packing container, the described food of putting into packing container is made of the resin film of the sidewall upper that the container that is provided with projection in inside, the cooking processed food that is accommodated in internal tank and hot melt spread on container, through hole to be set, cover above-mentioned through hole by above-mentioned resin film along the mode that connects the end face of above-mentioned projection in the table.
In addition, in patent documentation 4, put down in writing a kind of packaging body, this packaging body seals in the peristome upper limb of the container body of taking in meaningful thing by the lower surface bonds with resin film, wherein, the wall of container of container body is provided with through hole, form the protuberance of ring-type at the upper limb of this through hole, make the lower surface closed contact of the upper surface of this protuberance and above-mentioned resin film and not bonding, can be discharged to the outside from above-mentioned through hole from the gas that content produces.
Although the packaging body of the food of putting into packing container of patent documentation 3 and patent documentation 4 is simpler structure, can discharge from the through hole that is arranged at container from the gas that content produces, yet, have following shortcoming.That is, for the food of putting into packing container of patent documentation 3 and the packaging body of patent documentation 4, the gas fluid capacitance that produces at internal tank easily is stranded in part, and when utilizing heating such as micro-wave oven etc., different places are easy to generate heal differential.This heal differential becomes content and produces the uneven reason of heating, also may become the reason of the taste deterioration that is heated the food after the cooking.
And, for the food of putting into packing container of patent documentation 3 and the packaging body of patent documentation 4, after the gas of internal tank is discharged from above-mentioned through hole, become the low state of built-in pressure ratio external pressure of container easily, container might cave in to the inside after heating.These unfavorable conditions are not limited to the food of putting into packing container of patent documentation 3 and the packaging body of patent documentation 4, the automatic-cooking of patent documentation 1 with pack and other packaging body such as the packing container of patent documentation 2 in be not resolved yet.

Summary of the invention
The present invention finishes in order to solve above-mentioned problem, a kind of packaging body is provided, not only utilize simple structure to realize to be discharged to from the gas that content produces the packaging body of external container, and at gas when the through hole that is arranged at wall of container is discharged, can also can heat content equably at the inner gas stream that produces of entire container.And, the present invention also aims to, even also be difficult for the packaging body of depression to the inside after providing a kind of gas to discharge from above-mentioned through hole at internal tank.In addition, the present invention also aims to, provide a kind of and can be applicable to the container that constitutes this packaging body.
Above-mentioned problem solves by following packaging body is provided, this packaging body is by the lower surface of adhering resin film on first adhesive portion that is provided with in the form of a ring at the upper limb along container, the content that is accommodated in the container is sealed, it is characterized in that, on wall of container, be formed with first protrusion that is projected into internal tank and contacts, be provided with: the through hole that connects wall of container at the upper surface of first protrusion with the lower surface of resin film; Second adhesive portion of ring-type, the part that is used for surrounding this through hole is bonded in the lower surface of resin film more weakly; And compare the more second outstanding protrusion of highland with the upper limb of second adhesive portion, and when the internal pressure of container raises, thereby resin film expands upward second adhesive portion is stripped from, and the gas of internal tank is discharged to external container via above-mentioned through hole.
Thus, when the through hole that is arranged at wall of container is discharged, can utilize second protrusion to be controlled at the gas stream that internal tank produces at gas.Therefore, also can not only can heat content equably, and can gas be discharged from internal tank at the inner gas stream that produces of entire container.And,, can also make the gas of external container flow into internal tank naturally because the internal pressure of container and the resin film that expands upward during to original recovering state, can utilize second protrusion temporarily to support resin film.Therefore, can prevent that container caves in to the inside after the gas of internal tank is discharged from above-mentioned through hole.
Herein, " the more weak ground " of so-called " being used for being bonded in second adhesive portion of the lower surface of resin film " is that the bind strength of the resin film on expression second adhesive portion is lower than the bind strength of the resin film on first adhesive portion more weakly.Like this, by second more weak ground of the adhesive portion adhering resin film, make under normal conditions, keep the air-tightness of internal tank, when heating packaging body etc. makes that the internal pressure of container raises, can only peel off second adhesive portion simultaneously by in advance.In first adhesive portion, the bind strength of the degree that can not peel off if resin film is not deliberately peeled off with staff usually carries out bonding.
In above-mentioned packaging body, the position that above-mentioned through hole is set is not particularly limited, and preferably is arranged on upper limb (outer rim) from container near the position of leaving the central authorities more than the 5mm.This is because packaging body generally is to carry near the upper limb (outer rim) of grabbing container, so when above-mentioned through hole is in the near position of upper limb (outer rim) from container, when the packaging body of carrying after heating, point from possible the contact easily of hot gas that above-mentioned through hole produces.
The position that second protrusion is set is not particularly limited, but preferably observes from above-mentioned through hole, is configured in the container center side.Thus, can make the gas at the center that is present in internal tank after second protrusion is circuitous, arrive above-mentioned through hole, can keep the temperature of internal tank more equably.Distance from above-mentioned through hole to second protrusion is not particularly limited, but can be difficult to control the gas stream that arrives above-mentioned through hole if the above-mentioned through hole and second protrusion from too far, then have.Therefore, to be configured in the center radius apart from above-mentioned through hole usually be the following zone of 30mm to second protrusion.
If height from the front end of second adhesive portion to the front end of second protrusion is not particularly limited, but low excessively, then might can't utilize second adhesive portion that gas stream is made a circulation.On the other hand, if the excessive height from the front end of second adhesive portion to the front end of second protrusion, then might apply the power of part easily to resin film, resin film breaks easily.Therefore, the height from the front end of second adhesive portion to the front end of second protrusion is set at 0.1～3mm usually.
Also preferably be formed with slit at second protrusion.Thus, can be easily the gas of external container be imported internal tank from above-mentioned through hole, can prevent that further container caves in to the inside after heating.Therefore, can also form wall of container thinner, therefore, the amount of the required material that container can be shaped suppresses lessly, thereby also reduces the manufacturing cost of container easily.
Also separate by partition wall preferred container inside, and first protrusion and above-mentioned partition wall are provided with continuously.Thus, internal tank can be divided into a plurality of zones, content separately can be taken in according to its kind and size etc., can utilize the limited space of internal tank efficiently.And can improve the intensity of container.In addition, like this internal tank is divided into the packaging body that a plurality of zones form and when heating, between each zone, produces heal differential easily, adopt the meaning of formation of the present invention also more far-reaching.This formation is suitable for adopting when food such as box lunch and nonstaple food are taken in as content.
And, above-mentioned problem is also by providing following container to solve, first adhesive portion of the lower surface that is used for the adhering resin film of this container is provided with in the form of a ring along upper limb, it is characterized in that, on wall of container, be formed with and be projected into internal tank and reach first protrusion of equal height, be provided with at the upper surface of first protrusion: the through hole that connects wall of container with the upper limb of container; Second adhesive portion of ring-type, the part that is used for surrounding this through hole is bonded in the lower surface of resin film; And compare the more second outstanding protrusion of highland with the upper limb of second adhesive portion.This container can be applicable to above-mentioned packaging body.
As mentioned above, according to the present invention, can utilize the few simple structure of components number to realize to be discharged to from the gas that content produces the packaging body of external container.And can provide a kind of such packaging body: promptly, when the through hole that is arranged at wall of container is discharged, can also can heat content equably at the inner gas stream that produces of entire container at gas.Even and then also be difficult for the container of depression to the inside after also providing a kind of gas to discharge from above-mentioned through hole at internal tank.Can also provide a kind of in addition and can be applicable to the container that constitutes this packaging body.

9, slit
In addition, as shown in Figure 4, in the container 110 of present embodiment, be formed with slit in the longitudinally substantial middle portion of second protrusion 115.Therefore, thereby because gas when discharging the resin film 120 that makes the internal pressure of container 110 reduce, expand upward from through hole 113 to original recovering state, can make the gas of external container flow into internal tank (arrow C among Fig. 4) naturally, the distortion of the container 110 after can preventing to heat.Slit can only be arranged on a place at one second protrusion 115, also can on one second protrusion 115 many places be set.
The width of slit is not particularly limited according to from the distance of through hole 113 to second protrusions 115 and the volume of container 110 etc. and different.But,, then during to original recovering state, might be difficult to the exterior gas of container 110 is imported the inside of container 110 at resin film 120 if the width of slit is narrow.Therefore, the width of slit is set at more than the 0.5mm usually.The width of slit is preferably more than the 1mm, more preferably more than the 1.5mm.On the other hand, if the width of slit is wide, then might can't utilize the gas inside stream of second protrusion, 115 control containers 110.Therefore, the width of slit is set at below the 5mm usually.The width of slit is preferably below the 4mm, more preferably below the 3mm.In the container 110 of present embodiment, the width of slit is approximately 2mm.
10, resin film
The material of resin film 120 is not particularly limited, and can use various resins.Resin film 120 can be a single thin film, also can be multilayer film.Wherein, the multilayer film that the coincidence hot sealing layer forms on the resin bed that twin shaft extends are suitable for as resin film 120.This is because this multilayer film are little because of the distortion of heat, also can bear the heating of being undertaken by micro-wave oven, and also excellent aspect heat sealability.The resin film 120 of present embodiment is the resistance epoxy layer that constitutes by the substrate layer that will be made of biaxial stretched polypropylene, by polyacrylonitrile resin and overlaps the multilayer film that form by the hot sealing layer that poly-vinyl resin constitutes.The lower surface of resin film 120 (hot sealing layer) heat is deposited on first adhesive portion 111 that is provided with in the form of a ring along the upper limb of container 110.
The thickness of resin film 120 is not particularly limited, but if thin excessively, then resin film 120 might break easily.Therefore, resin film 120 single-piece thickness are set at more than the 30 μ m usually.The single-piece thickness of resin film 120 is preferably more than the 55 μ m, more preferably more than the 60 μ m.On the other hand, if resin film 120 is blocked up, even then the internal pressure of possible container 110 rises, resin film 120 also is difficult to expand laterally, and second adhesive portion 114 is difficult to peel off.Therefore, resin film 120 single-piece thickness are set at below the 80 μ m usually.The single-piece thickness of resin film 120 is preferably below the 70 μ m, more preferably below the 65 μ m.The single-piece thickness of the resin film 120 of present embodiment is 60 μ m.
11, action
Then, the action when utilizing micro-wave oven heating packaging body 100 describes.To be expression will heat before the beginning or the cutaway view of the state of cutting open of the through hole 113 in left side in the packaging body 100 of heating after just having begun on every side by the face that is equivalent to the Y-Y face among Fig. 4 Fig. 6.Fig. 7 is expression will heat the state of cutting open of the through hole 113 in left side in the packaging body 100 of beginning after a moment later on every side by the face that is equivalent to the Y-Y face among Fig. 4 a cutaway view.
Before packaging body 100 heating beginning or heat just begun after, as shown in Figure 6, resin film 120 is bonding by second adhesive portion 114, through hole 113 becomes by resin film 120 osed top states.The connectivity slots 117 of the gas of internal tank by being arranged at partition wall 116 upper limbs etc. flow between the low zone of the high zone of temperature and temperature naturally, can guarantee the circulation as the aqueous vapor of thermal medium between each zone.Therefore, the content 130 that is accommodated in each zone can not produce big heal differential.
After the heating of packaging body 100 begins a moment later, produce aqueous vapor from content 130, the internal pressure of container 110 begins to rise.Resin film 120 is owing to the internal pressure of internal tank 110 begins to expand upward.When the expansion of resin film 120 reached capacity, resin film 120 was stripped from the more weak second bonding adhesive portion 114, as shown in Figure 7, became the state that internal tank and external container are communicated with by through hole 113.In the first bonding strongly adhesive portion 111, resin film 120 also is in bonding state.
When internal tank and external container were communicated with by through hole 113, the gas of internal tank was discharged to external container (the arrow D among Fig. 7) by through hole 113.The gas that is discharged to external container at internal tank, arrives through holes 113 in the circuitous back of second protrusion 115 shown in arrow A and arrow B among Fig. 4, when through hole 113 was discharged, internal tank is whole to produce big gas stream at gas.Therefore, be accommodated in easy the maintenance evenly of temperature of the content 130 in each zone.
But, gas just from through hole 113 discharge the back, when through hole 113 is closed because the condensation and the contraction of the gas of internal tank make the built-in pressure ratio external pressure of container 110 low, the container 110 after the heating might cave in to the inside.But, in packaging body 100 of the present invention, after gas is discharged from through hole 113, also can be by the resin film 120 around second protrusion, the 115 supporting through holes 113.Therefore, the gas of external container flows into internal tank naturally by through hole 113 once more, and after the heating of packaging body 100, the internal pressure of container 110 can significantly not reduce.The gas that is imported into internal tank is not only by around the through hole 113, and by being arranged at the slit of second protrusion 115, thus, also can promptly arrive the central part (arrow C among Fig. 4) of container 110.Therefore, 110 depressions of the container after can preventing from more reliably to heat.
