Description

  The present invention relates to a sealed container.

Lunch boxes that have been marketed in the past may have a small bag filled with soy sauce, mayonnaise, or dressing. As shown in FIG. 5 , such a bag has two sheets 101 made of synthetic resin such as polyethylene and polypropylene, and is sealed by thermally welding the peripheral portion 102. A cut 103 is provided in a part that has been heat-welded, and the contents are taken out by cutting a part of the bag 100 from the cut 103 during use. In this product, the cut is made from the cut 103 and the contents are taken out by pressing the bag 100 with a finger. However, if the cut 103 is cut while the bag 100 is pressed, the contents may be scattered in an unexpected direction. Therefore, when opening such a bag, it is necessary to cut the cut 103 without pushing the bag 100 as much as possible, such as picking the peripheral edge portion 102.

  Further, in the case of a bag filled with a content that vaporizes at room temperature or a content having vapor pressure, the content pops out from the cut 103 even if the bag 100 is opened without being pushed. Therefore, there are procedures such as opening the cut 103 with the contents 103 facing the container and opening it carefully, or opening the cut 103 with the cut 103 facing upward, releasing only the gas, and then opening the gas greatly. is necessary.

On the other hand, as shown in FIG. 6, there is a type in which a narrow passage 104 having a closed tip is provided at a corner portion of the bag 100 and a cut 103 is provided so as to cut the middle of the passage. After this is cut like an imaginary line, the contents jump out in the direction of the passage 104. Therefore, there is an advantage that the container is easily received. However, the point that the contents jump out from the cut immediately after cutting is the same as the case described above, and the possibility of polluting the surroundings has not been sufficiently solved.

  The present invention provides a sealed container that does not spout immediately after opening even if it is opened in a state where it is accidentally pressed with a finger, and even if the contents have vapor pressure, and therefore has a low risk of splashing around. This is a technical issue.

The sealed container of the present invention comprises a bag-like container body composed of two sheets that are overlapped and welded at the periphery, and a discharge member connected to the container body. It is composed of a sheet interposed between the sheets and heat-welded together at the periphery, and has a partition wall that divides the interior of the container body into a plurality of chambers, and the discharge member has a leading end that opens to the outside of the container body. It is characterized in that it has a closed portion that is not communicated with the inside of the container body at a position apart from the distal end portion of the discharge member but is opened and communicated by an external force .

Which discharge member of such a sealed container is divided so as to be discharged separately each liquid chamber is preferred.
Furthermore, it is preferable that the inside of the container body is partitioned into two chambers.
Further, the sheet constituting the partition wall is thermally welded to the side surface of the discharge member, the interior of the container body is partitioned into at least two chambers by the discharge member, and each chamber is opened when the closing portion is opened. What is comprised so that it may communicate with is preferable.
The sealed container of the present invention is preferably one in which the two chambers are filled with a two-component hair dye or an adhesive, respectively.

The sealed container of the present invention comprises a bag-like container body composed of two sheets that are overlapped and welded at the periphery, and a discharge member connected to the container body. It is composed of a sheet interposed between the sheets and heat-welded together at the periphery, and has a partition wall that divides the interior of the container body into a plurality of chambers, and the discharge member has a leading end that opens to the outside of the container body. Because it has a closed part that is not communicated with the inside of the container body at a position away from the tip of the discharge member at all times but is opened and communicated by external force, different types of contents are mixed in each chamber. It can be filled so that it does not. Therefore, it can be used for filling two liquids such as a two liquid type hair dye and a two liquid type adhesive which are separated and stored at the time of filling and mixed for the first time at the time of use. Even if the inside of the discharge member communicates with the outside through the opening of the tip, the inside of the container body is sealed. When the closed portion is communicated with an external force, the contents are not directly ejected to the outside, but first enter the discharge member. Then, after the contents are accumulated in the discharge member to some extent, the contents come out from the opening of the discharge member. That is, in this sealed container, the discharge member functions as a buffer, and since there is a slight elapsed time from opening the closing part to discharging the contents from the tip of the discharge member, it suddenly jumps out of the discharge port. Absent. Therefore, the user can point the opening to the receiving tray in preparation for discharging the contents.

FIG 3a~c is a partial front view partially cut away showing another form state of the closed chain portion, respectively it (reference drawing). Figure 4a, b is a cross-sectional view showing an implementation form of the sealed container of the present invention, respectively. It is a partially notched top view which shows an example of the conventional sealed container. It is a partially notched top view which shows an example of the conventional sealed container.

Tightly sealed container 10 shown to reference 1, superimposed with bag-shaped container body 12 made of the peripheral portions 11 of two sheets heat welded, tubular discharge member that is furnished to the container body 13. In the sealed container of the present invention, the container body shown in FIGS. 4A and 4B is used instead of the container body 12.

  The sheet constituting the container body 12 is a flexible sheet made of synthetic resin, such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyethylene terephthalate, nylon, and the like that can be used for conventionally known sealed containers. Is used. Different types of materials, such as laminating a metal foil such as an aluminum foil having gas barrier properties, or laminating an outer layer film deposited with a metal such as aluminum, silica, carbon, etc. A laminate sheet obtained by laminating two or more films may be used. Further, the two sheets constituting the container body 12 are usually sheets of the same type of material, but different types of sheets may be used. Further, two sheets that are not thermally welded to each other may be used, and a film that can be thermally welded to both of them may be interposed between them. Further, an adhesive may be coated and adhered.

The discharge member 13 is a cylindrical member having a distal end portion 13b opened and a proximal end portion 13a closed, and is made of a synthetic resin such as polyethylene, polypropylene, polyethylene terephthalate. Other materials such as metal and glass may be used. The discharge member 13 preferably has such a hardness that the hollow portion is not crushed by the internal pressure of the contents. However, those having a flexible, but it may also be one flexible. A flat tab 14 is integrally provided at the base end portion 13 a of the discharge member 13. Root portion 14a of the tab 14 is in the form status of this has become the lid of the discharge member 13. On the outer periphery of the discharge member 13, it can be easily broken by bending or twisting at a position slightly closer to the distal end side from the base end portion 13 a, and before the break, the inside and outside of the discharge member 13 are hermetically sealed. An annular groove (weak line) 15 that maintains a liquid-tight state is formed. The weakening line 15 is the closing part of claim 1 and is arranged in the storage part S of the container body 12. In FIG. 1, the discharge member 13 has a circular cross-sectional shape, but may have an elliptical shape or a rectangular tube shape.

  As shown in FIGS. 2a and 2b, the vicinity of the proximal end portion 13a and the distal end portion 13b of the discharge member 13 are sandwiched between two sheets, respectively, to improve the airtightness and liquid tightness between the storage portion S and the outside. Heat welded or glued to maintain. In addition, you may heat-seal so that the knob | pick piece 14 may be pinched | interposed, and the adhesiveness of the discharge member 13 and a sheet | seat will become strong, and it will become easy to operate. Further, when the knob 14 is twisted, the thermal welding between the sheet and the discharge member 13 is difficult to peel off.

  In order to fill the sealed container 10 configured as described above, for example, one side of the peripheral edge 11 of the container body 12, for example, the lower side of FIG. Fill the contents, then heat weld and seal. As the contents, it is possible to employ any of the conventional fillings in bags, such as dressings, lotions, liquids such as shampoos and rinses, and creams such as mayonnaise.

  As shown in FIG. 2 b, the sealed container 10 filled with the contents and sealed has the storage portion S blocked from the outside. In order to open the sealed container 10, for example, the tip 13b or the center of the discharge member 13 is picked from the top of the container body 12 with one hand, and the pick piece 14 is picked and twisted with the other hand. If it does so, the discharge member 13 will be fractured | ruptured in the position of the weak line 15 of FIG. 2, and will isolate | separate into the base end part 13a side and the front-end | tip part 13b side. In addition, since the container main body 12 has flexibility, when twisting the knob | pick piece 14, it does not get in the way so much. Even after complete separation by the weakening line 15, the knob 14 and the base end portion 13 a are sandwiched between the container main bodies 12, so that they do not fall out and are attached to the container main body 12. However, since the portion of the weak line 15 once separated does not have a sealing action, the contents enter the inside of the discharge member 13 through the opening 16 generated by the breakage of the discharge member 13 as indicated by an arrow P.

  However, since the inside of the discharge member 13 has been hollow until then, even if the contents enter the cavity, the discharge member 13 is not immediately ejected from the opening of the tip portion 13b. And after some time has passed, the contents flow out of the opening. Therefore, the user can concentrate on the work when twisting the knob 14, and after breaking the discharge member 13 with the weakening line 15, the user can concentrate on pouring the contents from the opening to a tray or the like. Even if the contents are once in the discharge member 13 even after the breakage, a buffering effect is obtained. Therefore, even if there is an internal pressure, there is no possibility of being ejected together with the breakage.

  Therefore, the contents include components having a low vapor pressure at normal temperature such as water and alcohol, but also components having a vapor pressure at normal temperature such as butane, pentane and hexane, or components that generate a vapor pressure when mixed. May be. When a component having a vapor pressure is included, it is preferable that the component, a component blended together with the component, and the container body are cooled before filling. Even those having such a vapor pressure are not ejected after opening. In addition, the internal pressure generated by the vapor pressure may be effectively used and ejected with the pressure of the contents. Specific examples of the contents include water, lower alcohols, polyhydric alcohols, silicone oils, hydrocarbon oils, ester oils, hair treatment agents, set agents, matting agents, hair dyes, hair removal agents, etc. , Emollients, moisturizers, exfoliants, bactericides, disinfectants, cleansing agents, shaving agents, antiperspirants, antiphlogistics, pest repellents, lotions, colons, deodorants, whitening agents, etc. For example, those obtained by dissolving or dispersing active ingredients such as those for use, and those obtained by blending these with ingredients having the above-mentioned vapor pressure. Moreover, a surfactant, a thickener, etc. can be mix | blended according to a discharge form (mist, foam, cream, gel).

  In the sealed container 10 of FIG. 1, the closed portion is formed by the annular groove 15 formed in the vicinity of the base end portion 13 a of the discharge member 13, but when it is broken by bending, the upper surface side or the lower surface side of the discharge member 13 A linear groove may be formed in both, and may be formed in both. Moreover, you may form a weak line in a side surface side. Further, as shown in FIG. 3a, the discharge member 13 is separated in advance from the proximal end portion side 21 and the distal end portion side 22, the end surfaces 21a and 22a are brought into contact with each other, and the gap is made of aluminum foil. It may be sealed with a sheet 23 that can be easily broken.

  The closing part 25 shown in FIG. 3b opens the base end part 13a of the discharge member 13, and plugs a plug 27 into the opening part 26 in a liquid-tight state. A knob 28 is integrally provided at the end of the plug 27. In this case, when the knob 28 is picked and the plug 27 is pulled out from the proximal end portion 13 a of the discharge member 13, the inside of the discharge member 13 and the storage portion S of the container body 12 communicate with each other through the opening 26.

  In the closing part 30 shown in FIG. 3c, the base end part 13a of the discharge member 13 is formed in a cylindrical shape, and a cylindrical plug 31 is fitted in the inside thereof in a liquid-tight state. The proximal end portion 13a of the discharge member 13 and the plug 31 are formed with windows 32 and 33 that communicate with each other at specific rotational positions. Normally, the plug 31 is locked at a position where the windows 32 and 33 do not communicate with each other, and the plug 31 is rotated during use so that the windows 32 and 33 communicate with each other.

The sealed container 10 of FIG. 1 uses a knob or a knob as means for applying an external force when the closed portion is communicated, and these protrude from the container body 12. Therefore, it is easy to operate. However, if the sheet constituting the container body 12 is flexible enough to operate the knob from above, a knob or the like can be placed inside the container body 12.

  Further, the distal end portion 13 b of the discharge member 13 is not particularly limited, and may be protruded from the container main body 13. Further, a nozzle whose inner diameter is thinner than the inner diameter of the cavity of the discharge member 13 may be mounted. Furthermore, you may make it connect a tube to this.

4a and 4b show an embodiment of a sealed container in which the inside of the container body is partitioned by a partition wall. In the sealed container 34 of FIG. 4 a, a partition wall 36 made of a similar sheet is interposed between two sheets 35 constituting the container body, and is thermally welded together at the peripheral edge portion 11. The inner edge of the partition wall 36 is thermally welded to the side surface of the discharge member 13. Since the inside of the container main body 12 is divided into two chambers by a partition wall 36, the chambers 37 and 38 can be filled with different types of contents so as not to be mixed. Therefore, it can be used for filling two liquids such as a two liquid type hair dye and a two liquid type adhesive that are separated and stored at the time of filling and mixed for the first time at the time of use. It is preferable that such a sealed container 34 is filled also with the above-described content that generates a vapor pressure by mixing. As described above, the two liquids may be mixed in the discharge member and discharged in this state, but the discharge member may be divided and the two liquids may be discharged separately.

  When such a partition wall 36 is provided, the discharge member 13 is stabilized, and the shape retaining property of the entire container is also improved. Moreover, since there exists such an advantage, you may fill the same content. 1 can be opened by twisting the knob 14, but it is easier to bend the discharge member 13 so that the side opposite to the side where the partition wall 36 is provided is opened. Line 15 can be broken. The opening of the discharge member 13 thus opened communicates with any of the chambers 37 and 38, and two types of contents are mixed inside the discharge member 13, and then discharged from the opening at the tip. The partition wall 36 may be a single sheet, and the central portion may be heat-welded to one side of the discharge member 13, but in that case, by opening a window at a portion corresponding to the weakening line, etc. Communication between the storage portion S and the discharge member 13 is ensured.

  The sealed container 40 shown in FIG. 4b has a partition wall 41 for partitioning in the vertical direction in addition to the partition wall 36 for partitioning the storage portion in the left-right direction, and is divided into four chambers as a whole. Therefore, four types of contents can be filled. It can also be divided into three or more rooms.
