Description

  The present invention relates to a delamination container capable of gradually evaporating the contents out of the container and diffusing it into the air while maintaining high sealing performance.

  Conventionally, the prior art represented by the chemical | medical agent volatilization container of the structure which can perform the siphoning and volatilization of the liquid chemical | medical agent put into the container efficiently is known (for example, refer patent document 1). The container is used for containing a water-soluble liquid medicine such as a liquid fragrance or a liquid deodorant.

  The container shown in the above prior art not only has the ability to express high liquid absorbency and volatility with respect to a water-soluble drug with a single material, but also a plant fiber structure that does not break with some tension It is also a thing. In addition, it is possible to obtain a container as a finished product without going through complicated manufacturing processes such as combining sucking members and volatilizers with different materials and compositions, and making it a layer structure, so that it is dry and efficient with low manufacturing cost It is thought that a container can be manufactured well.

In addition to this, another prior art using a laminate peeling container for storing various products such as foods and cosmetics is known (for example, see Patent Document 2).
In this prior art, a container is formed by a flexible outer layer and an inner layer peelable from the outer layer, and the contents are contained inside the inner layer. Further, since a check valve is provided at the opening of the container, the contents can flow out from the inside of the inner layer to the outside, but cannot flow from the outside to the inside.

  According to the above prior art (Patent Document 2), when the deformation of the container is released after the container is squeezed and deformed and the contents are taken out, the outer layer of the container is formed by taking in air between the outer layer and the inner layer of the container. Restore the original shape. On the other hand, since the air flow from the outside into the inner layer of the container is blocked by the check valve, the shape of the inner layer does not follow the restoration of the shape of the outer layer. Thereby, it is thought that deterioration of the contents can be prevented over a certain period by preventing air from entering the inner layer while maintaining the outer shape of the container.

JP 2005-058550 A JP-A-2-258563

  However, the former prior art has been developed with a focus on achieving high volatility, and no consideration is given to the sealing performance of the container. Therefore, according to this technique, the volatilization of the contents exceeding the required amount proceeds rapidly, and it is difficult to maintain the use state for a long time while suppressing the volatilization amount to the necessary limit.

  On the other hand, in the latter prior art, since the opening is shielded by the check valve after the contents are taken out, it is possible to make the contents difficult to touch the air. Therefore, compared with the former prior art, the sealing performance is excellent, and it is possible to prevent the content from deteriorating. However, since the check valve is easily opened when the container body is pressed and the contents flow out, it is difficult to ensure the sealing performance inside the inner layer. Therefore, it is impossible to maintain high sealing performance.

  Then, this invention makes it a subject to provide the lamination peeling container which can vaporize the contents gradually outside a container, and can make it diffuse in air, maintaining high sealing performance.

In order to solve the above problems, the present invention employs the following solutions.
That is, the delamination container according to the present invention is formed of an outer layer in contact with the outside air and an inner layer that is releasably laminated with the outer layer and in contact with the contents, and has a mouth at one end and a bottom at the other end. The main body, the air introduction port formed in the container main body for allowing air to flow between the outer layer and the inner layer, and the container main body are separately formed so as to be fitted into the mouth portion in advance, and the mouth in the fitted state A lid that can seal the portion, and the lid is inserted into the container body with the lid fitted into the mouth, and at least a part of the lid is sealed to the outside. And a suction member that enables the contents to be sucked out of the container body.

As described above, in the present invention, the lid body and the container main body are formed as separate bodies, and the lid body can be fitted into the mouth portion forming one end of the container main body. And a container main body is sealed by fitting a cover body in a mouth part. The suction member is passed through the container body by fitting the lid, and the contents can be sucked out from the container body.
By adopting such a configuration, the container main body is sealed by the sealing body and kept in a sealed state until just before use, so that high airtightness can be maintained. Therefore, the content of the contents is prevented from gradually evaporating into the air as in the case where the lid is fitted in the container body, and the quality of the contents is maintained over a long period of time. be able to.

  In addition, since the suction member is provided in the lid in advance, it is not necessary for the user to perform the mounting operation, so the difficulty of the mounting operation can be eliminated and the use as a delamination container can be started reliably. It becomes.

  In addition, after the lid is fitted into the container body, the container body is sealed by the suction member, so that even if the container falls down during use, the contents will flow out of the container. Can be avoided.

In the present invention, the air inlet is preferably formed at the bottom.
Thereby, it can form comparatively easily rather than the case where an air inlet is provided in the other site | parts except the bottom part of a container main body, As a result, cost reduction can be achieved.

Moreover, in this invention, it is preferable that a cover body has the sealing member adhere | attached along the corner of the inner surface top part.
According to this embodiment, when the lid is fitted into the mouth portion, the sealing member is crimped to the joint between the inner surface top portion and the inner wall portion of the lid body, so that even a small gap that may occur can be blocked. In addition, it is possible to avoid air from flowing into the container through a gap that is resisted after the lid is fitted into the mouth. Thereby, deterioration of the contents can be prevented.

The mouth portion has a thread formed in the outer circumferential wall portion in a substantially circumferential direction, and the lid body has a groove corresponding to the screw thread formed in the inner wall portion thereof. It shall be fixed to the container body by being screwed along the thread.
By adopting the screw type, it is possible to improve the operability of the user when the lid is fitted into the mouth, and to fix the lid securely.

Furthermore, the lid body preferably has a seal member bonded along a groove formed in the inner wall surface.
According to this embodiment, when the lid is fitted into the mouth portion, the sealing member is crimped to the screw thread, so that a slight gap generated between the screw thread, the screw valley, and the groove is also closed and the fitting is performed. By improving the state, the inflow of air into the container can be completely blocked, and more excellent sealing performance can be exhibited.

  The lid has a sealing member formed in a substantially cylindrical shape passing through the top surface thereof and protrudes up and down, and the suction member is held through the central portion of the sealing member. preferable. Alternatively, a flat plate-shaped sealing member may be fitted and closed on the inner surface top of the lid, and the suction member may be held through the sealing member.

  According to this configuration, the contact point between the suction member and the lid that can serve as a vent inside and outside the container is securely closed by being crimped to the sealing member. After that, it becomes possible to continue to maintain the sealing property of the container and the quality of the contents.

  As described above, according to the delamination container of the present invention, the quality of the contents accommodated in the container during distribution in the market by fitting the lid part into the mouth part of the container body immediately before use. Can be maintained. And since the suction member is previously provided in the lid body, it becomes possible to improve the operability of the fitting operation. Furthermore, even after the start of use, the contents are volatilized out of the container through the suction member while reliably closing the small gap that may occur between the mouth and the lid, and maintaining the sealing performance of the container. be able to. Further, since the container is sealed, the outflow of contents can be avoided even if the container falls down during use.

It is the one side longitudinal cross-sectional view of the lamination peeling container of one Embodiment. It is a perspective view of a container main part and a lid of a lamination exfoliation container of one embodiment. It is a longitudinal cross-sectional view (It is equivalent to the figure which made FIG. 1 a both-sides sectional view and expanded the cover body 6) in the lamination peeling container of various embodiment. It is the bottom view of the lamination peeling container of one Embodiment, and the longitudinal cross-sectional view of the bottom part (cross-sectional view which follows the IV-IV line of (A) in FIG. 4). It is the perspective view which showed the usage example of the lamination peeling container of one Embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the lamination peeling container shown by the following embodiment is a preferable illustration, and this invention is not limited to this illustration.

  FIG. 1 shows a laminate peeling container 1 according to one embodiment cut longitudinally along a longitudinal center line, the right half of which is shown as a front view, and the left half of it as a cross-sectional view. As shown in FIG. 1, the delamination container 1 is roughly composed of a container body 16 and a lid body 6. The container main body 16 has a bottomed cylindrical shape, and an upper end portion thereof is a mouth portion having a reduced diameter in a neck shape. The lid 6 has a central portion covered with a sealing member 8, and a tubular suction member 10 penetrates the central portion of the sealing member 8. By attaching and fixing the lid 6 to the mouth of the container main body 16, the delamination container 1 is in a form in use, and the desired effects of the delamination container can be exhibited.

  The container body 16 is formed of an outer layer 2 (outer shell) and an inner layer 4 (inner bag) that are detachably stacked. The outer layer 2 and the inner layer 4 are blow-molded by overlapping non-adhesive resins so that they can be separated from each other. For example, the inner layer 2 is made of polypropylene (PP), ethylene vinyl alcohol resin (EVOH) having a barrier property against odor, oxygen or water vapor, cyclic polyolefin resin (COP), etc., and the outer layer 4 is made of Polypropylene (PP), polyethylene terephthalate (PET), etc. are used. The pinch-off portion 28 formed on the bottom portion 24 is formed by heat-sealing the inner layers 4 in the blow molding process and then cutting in the vertical direction to remove burrs and the like generated on the cut surface. Air is introduced into the air chamber 22 formed by peeling the inner layer 4 from the outer layer 2 from the outside of the container body 16 through the air inlet 26.

[Principle of introducing air into the air chamber]
In the delamination container 1 of the present embodiment, a lid body 6 having a sealing member 8 penetrating the suction member 10 at the center of the top surface is attached to the container body 16 and placed in the storage chamber 20 (= inside the inner layer 4). It is a container that is used by allowing the contained contents to permeate the suction member 10 and suck it up and volatilize it into the air.

  Since the storage chamber 20 is sealed by the sealing member 8, when the contents penetrate the suction member 10 and are sucked up, the storage chamber 20 is deflated by a volume corresponding to the sucked-up amount. Along with this, the pressure in the container body 16 starts to decrease, but since the air inlet 26 is provided in the container body 16, the action of drawing air from the outside of the container body 16 works. At this time, the inner layer 4 is separated from the outer layer 2 to form a space that can accommodate the air drawn between the outer layer 4 and the inner layer 2, that is, an air chamber 22.

  In this way, air is drawn into the air chamber 22 from the outside of the container body 16 through the air inlet 26, and the storage chamber 20 can be deflated until all the contents are sucked up. In addition, since the container chamber 20 is deflated by an amount corresponding to the amount of decrease in the contents, the container body 16 can be prevented from being maintained in a reduced pressure state, so that the container body 16 (outer layer 2) is deformed. The function of sucking up the contents can be prevented from being lowered. In addition, although the suction member 10 does not have perfect airtightness, since it is not a material that actively promotes ventilation, inflow (backflow) of air from the suction member 10 into the container hardly occurs.

FIG. 2 is a perspective view of the container main body 16 and the lid body 6 of the delamination container 1 according to the embodiment. In addition, although the usage form of the lamination peeling container 1 was shown in FIG. 1, what combined the container main body 16 and the cover body 6 shown in FIG. 2 becomes a form as a product of the lamination peeling container 1. FIG.
FIG. 2A is a perspective view of the container body 16. As shown in this figure, the container body 16 has a mouth portion 18 formed at the upper end thereof, from which the contents are filled. A thread 30 and a thread trough 34 are formed in the outer circumferential wall portion of the mouth 18 in a substantially circumferential direction. When the lid 6 described later is attached to the mouth 18, the lid 6 is threaded. 30 and is screwed up to the upper side of the neck ring 36.

  FIG. 2B is a perspective view of the lid body 6. As shown in this figure, the lid 6 has a top center portion closed by a sealing member 8, and a suction member 10 passes through the center portion of the sealing member 8. The suction member 10 is formed in an elongated tubular shape. When the lid body 6 is attached to the mouth portion 18, the suction member 10 is immersed in the contents filled in the abandoned body 16. Then, when the content that has penetrated into the suction member 10 is sucked up to the outside of the container, the content moves from the inside of the container to the outside of the container through the suction member 10, and gradually evaporates into the air over time. Spread.

  Moreover, the dotted line part in a figure represents the sealing member adhere | attached on the inner surface wall part of the cover body 6 in order to improve the sealing performance of a container. The structure of the inner wall portion of the lid 6 will be described in detail later.

  The sucking member 10 is made of a fibrous material that has excellent permeability and can easily absorb liquid. For example, natural fibers such as bamboo, rattan and wood pulp, and nonwoven fabrics made of polyester or polypropylene synthetic fibers are more preferable.

  In addition, the lamination peeling container 1 in this embodiment is used for accommodation of the liquid which mainly consists of a volatile substance. The container main body 18 as the primary product is filled with a liquid according to various usage purposes, and then sealed by attaching an aluminum seal or the like to the mouth 18. The container body 16 and the lid body 6 that are kept in a sealed state are not attached to each other, but become a final product in a state of being separated, and these are distributed to the market as a set product. Then, a person who has obtained a distribution product manually peels off the aluminum seal or breaks through the aluminum seal and attaches and fixes the lid 6 to the mouth of the container body 16 to fix the delamination container 1 of the present embodiment. Is in a state where it can be used and the original function of the delamination container 1 can be exhibited.

  By adopting such a distribution form and attaching the lid 6 to the container body 16 immediately before use, it is possible to avoid the contents from being vaporized and volatilized in the air during the distribution process in the market.

  Here, it is possible to envisage a use form in which the mouth 18 of the container body 16 is sealed in advance with a rubber plug or the like, and the suction member 10 is pierced through the stopper immediately before the user uses it. However, the operation of piercing the suction member 10 through a rubber plug or the like formed of a material having high sealing performance is not easy and requires a skillful technique, so there is a high possibility of failure. If unsuccessful, the suction member 10 as an accessory loses its strength to loosen and pierce, and in the worst case, the accessory may not be used. Therefore, in consideration of such concerns, the present embodiment adopts a method of attaching the lid body 6 with the suction member 10 already pierced.

  By the way, in many cases, the lid of a general delamination container is composed of a check valve formed of the same material as the sealing member 8 of the present embodiment. The check valve is common to the sealing member 8 in terms of the flow direction, that is, only allows outflow of contents from the inside of the container to the outside, and blocks inflow from the outside including the air into the container. However, the check valve is greatly different in structure from the sealing member 8 in that the sealing is released by squeezing the container and applying pressure so that the contents can flow out. In a container that employs a check valve, the sealed state is easily released, and thus it is not always possible to keep high sealing performance of the container.

  In contrast, the mouth portion 18 of the present embodiment adopts a form in which the container is sealed by mounting the lid body 6 covered with the sealing member 8 and fixing the lid body 6 to the container body 16. Therefore, even if pressure is applied to the container, the sealed state is not released, so that the sealing performance of the container can be reliably maintained.

  FIG. 3 is a longitudinal cross-sectional view of a lid body in the delamination container of various embodiments (corresponding to a view in which the lid body 6 shown in FIG. 1 is represented by a cross-sectional view on both sides). In FIG. 3, two examples are given for the form of the lid 6.

  FIG. 3A is an enlarged cross-sectional view of the lid 6 according to the first embodiment. In the first embodiment, the screw-type lid body 6 is screwed into the mouth portion 18 and is fixed to the container body 16. On the outer surface wall portion of the mouth portion 18, there are formed a screw thread 30 projecting in a substantially circumferential direction and a screw valley 34 corresponding to a wall surface located between the screw threads 30. A concave groove 32 corresponding to the thread 30 and the thread valley 34 is formed in the inner wall portion of the lid 6. The lid body 6 is guided by the screw thread 30 and is screwed into the mouth 18 by meshing the thread thread 30 and the thread valley 34 with the groove 32, and finally reaches the upper side of the neck ring 36 to reach the container body 16. Fixed.

  The lid 6 is press-fitted with a substantially cylindrical sealing member 8 at the center of the top surface, and a suction member 10 formed in an elongated tubular shape passes near the center line of the sealing member 8. . In this embodiment, since the width of the sealing member 8 covering the suction member 10 is larger than the thickness of the top surface of the lid body 6, the sealing member can be more stably fixed to the lid body 6.

  In addition, a sealing member is bonded to the lid 6 along the corners of the inner surface top and the grooves of the inner surface wall. In this way, when the lid body 6 is screwed into the mouth portion 18, the seal member is pressed against the screw thread 30 and the screw valley 34, and thus a slight gap generated between the screw thread 30, the screw valley 34 and the groove 32. These can be closed, and the fitting state of these can be improved, and more excellent sealing performance as a container can be exhibited.

  FIG. 3B is an enlarged cross-sectional view of the lid 6 according to the second embodiment. Also in the second embodiment, the screw-type lid body 6 is screwed and fixed to the mouth portion 18 of the container body 16, and the sealing member is bonded to the inner surface of the lid body 6. Although it is the same as that of (A) in FIG. 3, the form of the sealing member which covers the center part of the top | upper surface of the cover body 6 differs greatly.

  The lid body 6 in this embodiment has a flat plate-shaped sealing member 8 fitted to the inner top surface thereof, and a suction member 10 formed in the shape of an elongated tube at the center of the sealing member 8. Has penetrated. In this embodiment, since the sealing member is formed with a small thickness to penetrate the suction member 10 as compared with the first embodiment, it is convenient in that the suction member 10 can be more easily penetrated through the sealing member 8. There is.

  The sealing member 8 is made of a soft resin such as a thermoplastic elastomer such as a styrene elastomer in addition to a rubber such as butyl rubber. By adopting these materials, excellent chemical resistance and sealing properties can be exhibited. More preferably, the hardness of the sealing member 8 is such that the suction member 10 can penetrate the sealing member 8 and can maintain the sealing performance, specifically, the durometer A based on the standard of JISK6253 is 30-80. . Further, the thermoplastic elastomer is preferably a styrene elastomer having a melting point of 135 to 200 ° C.

  FIG. 4 is a diagram showing in detail the bottom 24 of the delamination container 1 according to one embodiment. 4A is a bottom view of the container body 16 of the delamination container 1, and FIG. 4B is a longitudinal sectional view of the bottom 24 (a cross section taken along line IV-IV in FIG. 4A). Respectively).

  A pinch-off portion 28 is formed on the bottom portion 24 along a straight line passing through the approximate center of the bottom surface. The pinch-off portion 28 is formed by heat-sealing the inner layer 4 in the process of blow-molding the container main body 16 and is in a completely sealed state. Etc. will not enter. On both sides of the pinch-off portion 28, air inlets 26 are provided for taking air into the air chamber 22 formed between the outer layer 2 and the inner layer 4. The surface of the bottom 24 is the outer layer 2, and the outer layer 2 is opposed to the pinch-off portion 28 on both sides of the air inlet 26.

  FIG. 5 is a perspective view showing an example of use of the delamination container 1 according to one embodiment. The volatile substance C contained in the delamination container 1 is infiltrated into the suction member 10 penetrated through the sealing member 8, sucked up to the outside of the container, and gradually vaporized from the exposed part in the air. The content C is volatilized in the air and used. In addition, the content C assumes the volatile solution, such as water, alcohol, and glycerin other than a fragrance | flavor and a deodorizer, for example.

  FIG. 5A is a perspective view showing an example of an initial stage of use of the delamination container 1, that is, a stage immediately after the user attaches the lid body 6 to the mouth portion 18 and fixes it to the container body 16. As shown in this figure, at this stage, the contents C have not yet permeated into the sucking member 10 and have not been sucked out of the container.

  FIG. 5B is a perspective view showing an example of the process of using the delamination container 1, that is, the time when the user has attached the lid 6 to the mouth 18 and fixed it to the container body 16. is there. As shown in this figure, the content C that has penetrated into the suction member 10 with time has been sucked up to the outside of the container. Since the sucked up contents C have volatility, an action of gradually evaporating from a portion exposed to the air of the suction member 10 occurs. Thereby, a volatile component can be volatilized in the air.

In any of the usage examples, the delamination container 1 is kept in a sealed state, so that it is possible to avoid the quality deterioration of the contents C in the distribution process before use.
A support (protection) enclosure may be provided around the suction member 10.

  As described above, according to the delamination container 1 of the present embodiment, even if the contents stored in the storage chamber 20 are sucked up by the suction member 10 and the storage chamber 20 is deflated, the inside of the container starts to have a reduced pressure. Since air does not flow into the container, the quality of the contents C can be maintained for a long time.

  In addition, since the container is formed with the lid 6 and the container body 16 as separate bodies and these are mounted when used, the contents gradually vaporize in the air as the product filled with the contents C circulates in the market.・ It is possible to avoid volatilization. Furthermore, since the suction member 10 is pierced in advance in the lid body 6, a failure due to the user performing the piercing operation himself does not occur.

  A sealing member is bonded to the lid body 6 along the corner of the inner surface top and the groove of the inner wall surface, and the sealing member is crimped to the screw thread 30 when the lid body 6 is screwed into the mouth portion 18. Further, even a slight gap generated between the screw thread 30, the screw valley 34, and the groove 32 can be closed, and the fitting state of these can be improved, and more excellent sealing performance as a container can be exhibited.

  Furthermore, the sealing member 8 is fitted or press-fitted into the central portion of the top surface of the lid body 6, and the suction member 10 penetrates through the central portion, thereby maintaining the sealing performance of the container during use. be able to. Moreover, since the container is sealed, the outflow of contents can be avoided even when the container falls during use.

  The present invention can be implemented with various modifications without being limited to the above-described embodiment.

  For example, in the delamination container 1 of the above-described embodiment, the resin constituting the outer layer 2 and the inner layer 4 has a single-layer structure, but it can also have a multilayer structure, and is appropriately selected depending on the situation. It's okay.

  Moreover, although the suction member 10 was made into the form penetrated by what was formed in the elongate tubular shape, it is good also as using the multiple suction member 10, and also selecting thickness suitably according to a condition. Is possible.

  Furthermore, a filter paper may be set on the upper part of the suction member 10 in order to promote the vaporization and volatilization of the contents C.
