Description

  The present invention relates to a container with a cap, and in particular, includes a flexible outer container and an inner bag disposed inside the outer container, and a mouth portion has a space between the outer container and the inner bag. The present invention relates to a container with a cap constituted by a container main body in which an air replacement port for sending air is formed and a cap attached to cover the mouth of the container main body.

  A so-called laminated double peeling container comprising a container body composed of an outer container having flexibility and an inner bag disposed inside the outer container is used in various ways as a container for storing cosmetics, cleaning agents, chemicals, and the like. (For example, refer to Patent Document 1). In these laminated double peeling containers, for example, after mounting a discharge nozzle or applicator equipped with an air valve or a liquid discharge valve on the mouth part of the container body, the outer container was accommodated inside the inner bag while being deformed by pressing. Use while discharging contents. Even if the volume of the contents decreases due to the discharge of the contents, air is sent from the air replacement port formed in the neck of the container body to the hollow part between the outer container and the inner bag to restore the outer container to its original shape. The outer shape of the container by the outer container can be maintained by returning and deforming only the inner bag.

  A container having a container body composed of an outer container and an inner bag is used, for example, as a container for a hair dye that is a cosmetic that generates gas. For example, a second agent made of an oxidant is used as an inner bag of the container body. May be housed inside. In such a hair dye container, when the hair dye is used, the cap attached to the mouth part of the container body is removed, and the first agent made of, for example, oxidative hair dye contained in another container is mixed. At the same time, the discharge nozzle and the applicator are remounted on the neck of the container body, and a large amount of gas is generated from the inside of the inner bag by mixing the oxidative hair dye and the oxidant.

On the other hand, in a container for storing such contents that generate gas, the mixed contents deteriorate with generation of gas, so that the contents are often used as disposable containers. Disposable containers that contain gas-generating contents can be removed with the discharge nozzle and applicator removed and the cap reattached with the contents remaining inside the inner bag. When stored or discarded, the container may be deformed or damaged by expansion due to gas generated from the remaining contents. For this reason, a cap-equipped container having a function of allowing the gas generated from the remaining contents to escape to the outside even when the cap is erroneously attached has been developed (see, for example, Patent Document 2). ).

  A container with a cap, which is composed of a container main body formed of an outer container having flexibility and an inner bag, in which an air replacement port for sending air to the neck is formed, and a cap attached to cover the mouth of the container main body In the state before using the container, the top surface portion of the cap is tightly attached to the upper end of the mouth portion with appropriate packing or the like, so that the sealing performance is exhibited and the cap is accommodated inside the inner bag. Prevent the contents from leaking out. However, if the inner bag is made of a material that allows the vaporized gas such as decomposition gas or volatile gas from the contained contents to pass therethrough, the space and mouth between the outer container and the inner bag Volatilized gas diffuses from the periphery of the cap into the outside air through the air replacement port formed in the neck. This makes it difficult to keep the active ingredient concentration of the contents contained in the inner bag within a certain range for a long time.

  In a container with a cap including an outer container and an inner bag, since the hollow portion between the outer container and the inner bag and the outside air communicate with each other via an air replacement port provided in the mouth neck portion of the container body, During distribution, sales, storage, etc. before using the container, the volatilized gas that passes through the air replacement port and permeates the inner bag is likely to diffuse into the outside air. Therefore, before the use of the container, the diffusion of the volatilized gas that permeates the inner bag to the outside air is prevented and the contents contained in the inner bag are prevented without impairing the function of allowing the gas to escape after the container is used. Development of a technique that makes it possible to maintain the active ingredient concentration within a certain range for a long time is desired.

  The present invention comprises a flexible outer container and an inner bag disposed inside the outer container, and a cap is attached to the mouth part of the container body in which an air replacement port is formed in the mouth part. An object of the present invention is to provide a container with a cap that can effectively prevent volatilization gas from the contents from diffusing into the outside air before the container is used.

  The present invention consists of an outer container having flexibility and an inner bag disposed inside the outer container, and air that feeds air into a space between the outer container and the inner bag at the mouth A container with a cap configured by a container main body in which a replacement port is formed and a cap attached so as to cover the neck portion of the container main body, the cap being below the top surface portion and a peripheral portion of the top surface portion And an inner skirt portion disposed concentrically on the inner side of the skirt portion and extending downward from the top surface portion, and the cap has the top surface portion at an upper end of the mouth portion. The inner skirt portion is attached to the mouth portion in a close contact state, and the lower end portion of the inner skirt portion is air tightly attached to the inner peripheral surface of the mouth portion over the entire circumference, and the mouth portion of the outer container The upper end of the inner bag between the inner peripheral surface of The are sandwiched by the is sandwiched position to provide a capped container is below the air displacement ports, is obtained by achieving the above object.

  According to the container with a cap of the present invention, the mouth part of the container body, which includes an outer container having flexibility and an inner bag disposed inside the outer container, and an air replacement port is formed in the mouth part. In a container having a cap attached thereto, it is possible to effectively prevent volatilization gas from the contents from diffusing into the outside air before the container is used.

  A container 10 with a cap according to a preferred embodiment of the present invention shown in FIG. 1 is a container that contains, for example, a second agent of a hair dye as a content, and the container body 11 thereof has flexibility. For example, the container is a double-structured container composed of a substantially cylindrical outer container 12 and an inner bag 13 detachably mounted inside the outer container 12. For example, when a hair dye is used by attaching a comb discharge nozzle 20 (see FIG. 3) to the mouth portion 14 of the container body 11, the outer container 13 is gripped by hand and pressed and deformed. The agent can be discharged, and when the pressed state is released, the outer container 12 can be restored to the original substantially cylindrical shape while air is fed into the space 15 between the outer container 12 and the inner bag 13. It has a function as a so-called delamination double container.

  On the other hand, the hair dye is obtained, for example, by adding and mixing the first agent made of the oxidative hair dye contained in another container to the second agent made of the oxidant housed in the inner bag 13 of the container body 11. It is done. When the second agent and the first agent are mixed, a large amount of gas is generated inside the container body 11. In the present embodiment, for example, after the container 10 is used, the user mistakenly caps the hair dye, which is a mixture of the second agent and the first agent that generates a large amount of gas, while remaining in the inner bag 13. Even when the hair 16 is reattached and the hair dye is stored in the container 10 or discarded, the gas escapes from the periphery of the cap 16 (see FIG. 2) to avoid deformation or breakage of the container 10 due to expansion. it can. In addition, before the container 10 is used, it is possible to prevent the volatilization gas from the second agent from diffusing into the outside air for a long period of time and to keep the concentration of the active ingredient contained in the second agent within a certain range. That is, for example, when an oxidizing agent is contained in a conventional container with a cap attached to a double container, the concentration of hydrogen peroxide changes from 5.7% at the initial stage to 6.2% after three years. Even in a storage environment, the container 10 with a cap according to the present embodiment, for example, the concentration of hydrogen peroxide in the contained oxidizing agent is about 5.9% even after 3 years from the initial concentration of 5.7%. In addition, the increase in concentration can be suppressed.

  And the container 10 with a cap of this embodiment consists of the outer container 12 which has flexibility, and the inner bag 13 arrange | positioned inside the outer container 12, and the outer container 12 and the inner bag 13 are provided in the mouth part 14.

As shown in FIG. 2, the cap 16 includes a top surface portion 18, a skirt portion 19 extending downward from the peripheral portion of the top surface portion 18, and a concentric arrangement inside the skirt portion 19. The cap 16 is attached to the mouth portion 14 with the top surface portion 18 being in close contact with the upper end of the mouth portion 14, and the inner skirt portion 21 has a lower end portion 21a. But The upper end portion 13a of the inner bag 13 is sandwiched between the inner peripheral surface of the outer neck 12 and the inner peripheral surface of the outer container 12 in a state in which the inner peripheral surface of the outer neck 12 is tightly and tightly adhered to the inner peripheral surface. This position is below the air replacement port 17.

  Further, in the present embodiment, the inner skirt portion 21 is attached to the cap 16 integrally with the inner plug 28 composed of the inner skirt portion 21 and the top plate portion 27 with the top plate portion 27 overlapped with the top surface portion 18. Thus, it extends downward from the top surface portion 18. Further, the inner plug 28 is attached to the cap 16 integrally with the packing 23 sandwiched between the top surface portion 18 and the top plate portion 27.

  Furthermore, in this embodiment, the packing pressing portion 22 is provided on the lower surface (inner surface) of the top surface portion 18 of the cap 16. The packing 23 is sandwiched between the packing pressing portion 22 and the upper end 14a of the mouthpiece 14 of the container body 11 with the projecting flange 27a of the top plate 27 of the inner plug 28 interposed on the upper end 14a side of the mouthpiece 14. In this state, a cap 16 is attached to cover the mouth portion 14. In addition, the packing pressing portion 22 can contact the upper end 14a of the mouth portion 14 from the lower surface side of the packing 23 with the protruding flange portion 27a of the top plate portion 27 of the inner plug 28 interposed therebetween, and the packing pressing portion 22. Are provided on the top surface portion 18 so that the packing 23 has a free portion 23a that does not come into contact with the upper surface side.

  In the present embodiment, the outer container 12 is a substantially cylindrical container made of, for example, polyethylene, and has such flexibility that the outer container 12 can be deformed into a flat shape by being held and pressed by a hand. In addition, it has a shape-retaining property (elasticity) that can be naturally restored to the original substantially cylindrical shape when the pressed state is released. Therefore, by pressing and deforming the outer container 12, the hair dye contained in the inner bag 13 can be discharged, and the container body 11 can function as a squeeze container (see FIG. 3).

  Further, the outer container 12 is provided with a mouth portion 14 at the upper end portion thereof with a shoulder portion 26 interposed between the outer portion 12 and the body portion 25. The neck portion 14 is provided with a male thread ridge 24 on the lower outer peripheral surface thereof. Above the male screw ridge 24, an air replacement port 17 that communicates the inside and the outside of the mouth portion 14 is provided. Openings are formed at two locations so as to face each other in the radial direction of the neck portion 14. Further, an annular convex rib 31 having a substantially isosceles trapezoidal cross-section is provided on the neck portion 14 on the inner peripheral surface below the air replacement port 17 so as to protrude inward over the entire circumference. The inner skirt portion 21 tightly adheres to the convex rib 31 in a state where the upper end portion 13a of the inner bag 13 is sandwiched.

The inner bag 13 is a bag-like container made of silicone, natural rubber, low-density polyethylene, high-density polyethylene, polystyrene, polypropylene, ionomer, polyester elastomer, or the like having a thickness of about 10 to 1000 μm, for example. The inner bag 13 has a permeation performance measured by, for example, the A method (differential pressure method) in the gas permeability test method for plastic films and sheets specified in JIS K 7126. For example, the inner bag 13 is 0 when the O ₂ permeability coefficient is 25 ° C. A transmission performance of 5 × 10 ⁻⁷ (cm ³ · cm / cm ² · s · Pa) or more is provided. Thereby, the inner bag 13 can permeate | transmit the volatile gas which arises from the water | moisture content and alcohol contained in the 2nd agent of the hair dye accommodated, the decomposition gas which arises from another active ingredient, etc. as volatilization gas.

  Further, the inner bag 13 is mounted inside the outer container 12 in a state in which it is detachably attached to the inner side surface of the outer container 12 except at least a part thereof. It is attached to the outer container 12 by welding and joining to the upper end 14 a of the neck portion 14. Further, the inner bag 13 maintains a gap without being in close contact with the inner side surface of the outer container 12 at least in a portion around the air replacement port 17 formed in the neck 14 and directly below the annular convex rib 31. These space portions form a space portion 15 between the outer container 12 and the inner bag 13 that can communicate with the outside air via the air replacement port 17.

  The cap 16 is, for example, a plastic molded product made of polyethylene. In this embodiment, the cap 16 is formed integrally with the inner plug 28 having the separately formed inner skirt portion 21 as described above. The cap 16 includes a top surface portion 18 and a skirt portion 19 that extends downward from the peripheral portion of the top surface portion 18. The top surface portion 18 has a disk shape, and includes a packing pressing portion 22 on a lower surface which is an inner surface thereof. When the cap 16 is attached to the neck part 14 of the outer container 12 (container body 11), the packing pressing part 22 is located between the upper end 14a of the mouth part 14 while interposing the top plate part 27 of the inner plug 28. A flat pressing surface for sandwiching the packing 23 is provided. The packing pressing portion 22 is provided with a recessed portion 29 formed, for example, by cutting the pressing surface into a concave shape in at least a part of an area having a substantial width that overlaps the upper end 14a along the upper end 14a of the mouthpiece portion 14. . By this recess 29, only the upper end 14a of the mouth part 14 can be brought into contact with the packing 23 (with the overhanging flange 27a of the top plate 27 of the inner plug 28 interposed) from its lower surface side, and the packing pressing part 22 A region that does not contact the packing 23 is formed in the circumferential direction. As a result, the free portion 23a to which the packing 23 can move upward is inserted into the packing 23 sandwiched between the upper end 14a of the mouth 14 and the packing pressing portion 22, for example, the annular flange portion 13b and the inner plug of the inner bag 13 In this state, the overhanging flange portion 27a of the 28 top plate portions 27 is interposed between the upper end 14a of the mouthpiece portion 14.

  Since the packing 23 sandwiched between the upper end 14a of the mouth part 14 and the packing pressing part 22 has a free part 23a at least partially along the upper end 14a of the mouth part 14, for example, the container 10 Even when the user accidentally reattaches the cap 16 to the mouth portion 14 while the hair dye that generates a large amount of gas remains inside the inner bag 13 after use, and the hair dye is sealed in the container 10. The generated gas can be released smoothly to the outside air. That is, due to the pressure of the generated gas, the packing 23 is bent so as to warp upward in the free portion 23a (see the broken line portion in FIG. 2), and the mouth portion 14 in which the annular flange portion 13b of the inner bag 13 is integrally joined. A gap is formed between the upper end 14a. The generated gas is allowed to flow out through the gap, and can be smoothly discharged from the periphery of the cap 16 to the outside air.

  The packing 23 is a disk-shaped flat plate member made of polyolefin, silicone rubber or the like, and various packings generally used in conventional containers with caps can be used without any special processing. The packing 23 has a thickness of about 0.5 to 3 mm, can be deformed so as to be warped by receiving a load in a bending direction, and can be easily restored to its original flat shape (shape retention). It is preferable to provide.

  The skirt portion 19 of the cap 16 is a cylindrical sleeve-like portion integrally extending downward from the peripheral portion of the top surface portion 18, and has an external thread ridge of the mouth portion 14 of the outer container 12 on its inner peripheral surface. Female thread ridges 30 that are threadedly engaged with 24 are provided.

  The inner plug 28 attached integrally to the cap 16 is an injection-molded product made of, for example, polyolefin, polyamide, polyester, and the like, and includes the top plate portion 27 and the inner skirt portion 21 as described above. The top plate portion 27 is provided with a disk shape that covers the upper end opening of the neck portion 14 of the outer container 12. The top plate portion 27 has an overhanging flange portion 27a at the outer peripheral edge of the top plate portion 27 in close contact with the upper end 14a of the mouth portion 14 to which the annular flange portion 13b of the inner bag 13 is integrally joined. When it is mounted on the mouth portion 14, it exerts a sealing function that prevents the contained contents from leaking out.

  The inner skirt portion 21 is a cylindrical portion that extends downward as a unit from the lower surface of the top plate portion 27 in a state in which the overhanging flange portion 27a projects outward. The inner skirt portion 21 is disposed concentrically with the inner plug 28 inside the skirt portion 19 of the cap 16 by integrating the inner plug 28 with the cap 16. The inner skirt portion 21 includes a bulging contact portion 21b that expands outward at the lower end portion 21a. When the cap 16 is attached to the mouth 14 of the outer container 12, the bulging contact portion 21 b is in a state where the upper end portion 13 a of the inner bag 13 is sandwiched between the annular convex ribs 31 provided on the inner peripheral surface of the mouth 14. Adhere tightly over the entire circumference.

  Further, in the present embodiment, the exhaust hole 32 is disposed in the top plate portion 27 of the inner plug 28 so as to overlap with the free portion 23 a of the packing 23 inside the inner skirt portion 21. By forming the exhaust hole 32 in the top plate portion 27 of the inner plug 28, for example, the cap 16 in which the inner plug 28 is integrated is used while the hair dye remains in the inner bag 13 after the container 10 is used. Even if a person mistakenly attaches to the mouth part 14 and encloses the hair dye in the container 10, the generated gas can be smoothly released to the outside air. That is, due to the pressure of the gas generated through the exhaust hole 32 of the inner plug 28, the packing 23 is bent so as to warp upward in the free portion 23a (see the broken line portion in FIG. 2). As a result, the packing 23 is integrally joined with the annular flange portion 13b of the inner bag 13, and between the upper surface of the overhanging flange portion 27a of the upper end 14a of the mouth portion 14 on which the overhanging flange portion 27a of the inner plug 28 is placed. Therefore, the gas generated through the gap is allowed to flow out and can be smoothly released from the periphery of the cap 16 to the outside air.

  In the present embodiment, the male thread ridges 24 of the neck part 14 of the outer container 12 and the female thread ridges 30 of the skirt part 19 of the cap 16 are intermittent screws in which a part in the circumferential direction is cut away. ing. As a result, a gas outflow passage that crosses the male thread ridges 24 and the female thread ridges 30 in the vertical direction is formed between the mouth portion 14 and the skirt portion 19 at an appropriate position. The gas generated from the hair dye enclosed by the cap 16 flows out from the free portion 23a of the packing 23 and then flows down along the outflow path. The lower end of the skirt portion 19 and the base end portion of the mouth portion 14 It becomes possible to diffuse into the outside air through the gap between the two.

  The cap-equipped container 10 of the present embodiment having the above-described configuration is configured such that the cap 16 in which the inner plug 28 and the packing 23 are integrated is screwed and attached to the mouth 14 of the container body 11, thereby lowering the lower end of the inner skirt portion 21. The portion 21a is manufactured in a state of being in airtight contact with the inner peripheral surface of the mouth portion 14 over the entire circumference, and is used for distribution, sale, or storage. In such a state before the container 10 is used, the upper end portion 13 of the inner bag 13 is sandwiched between the lower end portion 21 a of the inner skirt portion 21 and the inner peripheral surface of the neck portion 14 below the air replacement port 17. Meanwhile, the container main body 11 is in airtight contact with the inner peripheral surface of the mouth portion 14. As a result, the volatilized gas that has passed through the inner bag 13 and reached the space 15 between the inner bag 13 and the outer container 12 flows firmly toward the air replacement port 17 below the air replacement port 17. Since it is cut off, it is possible to effectively prevent the volatilization gas from diffusing to the outside air through the air replacement port 17, and the active ingredient concentration of the second agent of the hair dye contained in the inner bag 13 is within a certain range. It can be held for a long time.

  Therefore, according to the container 10 with a cap of this embodiment, it becomes possible to effectively prevent the volatilized gas from the contents from diffusing into the outside air before the container 10 is used.

  A user who purchases such a container 10 with a cap releases the fastening state of the container body 11 to the mouth part 14 by rotating the cap 16, removes the cap 16, and adds the first agent. If necessary, the cap 16 is reattached, and the second agent and the first agent are mixed to form a hair dye. Further, as shown in FIG. 3, for example, a comb discharge nozzle 20 is attached to the mouth portion 14 of the container body 11 and used as a delamination double container.

  Since the hair dye obtained by mixing the second agent and the first agent inside the container body 11 deteriorates while generating a large amount of gas, the container body 11 containing the cap is used as a disposable container. Generally, it is discarded together with 16. On the other hand, depending on the user, with the hair dye remaining inside the container body 11, the cap 16 is remounted on the container body 11 and discarded, or the remaining hair dye is stored. There is a case. In this embodiment, even when the cap 16 is reattached to the mouth neck portion 14 of the container main body 11 in this way, the generated gas retains the function of letting the gas escape from the container main body 11 filled with the hair dye. It is possible to effectively avoid the container 10 from being deformed or damaged by being expanded by the above.

  That is, in the present embodiment, the packing 23 is bent so as to bend upward in the free portion 23a, thereby generating gas generated from the inside of the inner bag 13 through a gap between the upper end 14a of the mouthpiece portion 14. Has a function to drain. The gas flowing out from the free portion 23a of the packing 23 flows out of the gas thread ridge 24 and the female thread ridge 30 in the vertical direction, the lower end of the skirt portion 19 of the cap 16 and the mouth of the container body 11. Since it can escape easily from the circumference | surroundings of the cap 16 toward outside air through the clearance gap between the base end parts of the neck part 14, it can avoid effectively that the container 10 expand | swells by these. Become.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, as a means for escaping gas generated from the remaining contents, various other gas outflow means can be adopted in addition to the provision of a free portion in the packing. By applying the present invention to a container that does not have a means for escaping gas or packing, it is possible to prevent volatilization gas from diffusing from the contents to the outside air before using the container. In addition, the cap does not necessarily have to be arranged concentrically on the inner side of the skirt by attaching a separately molded inner plug as a unit, and the inner skirt should be interposed via the inner plug Alternatively, it may be integrally formed with the cap. Furthermore, the contents to be stored need not be the hair dye or the second agent of the hair dye, but may be various substances including gas generating components such as other cosmetics, cleaning agents, and medicines. The present invention can also be used as a container that contains various substances that do not contain a gas-generating component, and can preferably contain contents that generate a large amount of gas by decomposition or fermentation. Furthermore, the gas leakage prevention cap does not necessarily need to be a screw fitting type cap.
