Definitions

  • the invention relates to a wide-mouthed pouch (a bag-like flexible container) suitable for collecting a sample of water, soil, sand, sludge, or the like, and a spout which is suitably used in the wide-mouthed pouch.
  • a bag-like flexible container i.e., a so-called freestanding pouch is practically used in which a plurality of films made of a resin or the like are joined together into a bag-like shape, and the joint portion is provided with an appropriate strength, thereby allowing a bottom portion to be unfolded by the own weight of the contents such as liquid when the contents are put into the container.
  • a freestanding pouch with a lid is also practically used in which an opening portion of such a pouch is integrated with a molded piece (a so-called spout) to which a screw-type lid having a bore diameter of about 20 mm is attached, by heating and fusion in a condition where the molded piece is interposed, so that the contents can be taken out in small quantities.
  • a base portion of the molded piece to which the lid is attached has a boat-shaped or streamline-type lateral profile, in order to attain high conformability with the opening portion of the pouch so as to easily come into close contact with each other.
  • Wide-mouthed bottles used for collecting sample water for water examination or the like are mostly various plastic molded products. Such wide-mouthed bottles are light weight, but have a predetermined volume so as to be bulky even when the bottles include no contents. Thus, there exists a problem in that a large space is required for storage when they are not used, transportation, or the stock of the products. There are further problems in that, since such a kind of wide-mouthed bottle is a plastic molded product, recycling can be performed with a certain degree, but the recycling requires a high cost, and that the operation of washing the inside for the recycling expends time and effort.
  • the above-mentioned freestanding pouch is superior in that it occupies almost no space when it includes no contents, and also in that it requires a low cost and is disposable.
  • a pouch is not suitable as a container for collecting a sample in the above-mentioned water examination, or the like.
  • a container is held by, for example, one hand, and the sample water is dipped and put into the container by a dipper held by the other hand, or a container is directly immersed into the water to be examined for dipping, so that the sample water is accommodated in the container.
  • a freestanding pouch the opening portion is almost in a closed condition in a natural condition in which any contents are not included. Therefore, the freestanding pouch is not suitable for the above-mentioned collecting procedure of the sample water or the like.
  • a pouch with a lid in which (a spout) capable of attaching a lid is attached to the opening portion by fusion is used, so that the pouch with a lid is not suitable for putting the sample water thereinto by a dipper or the like, or for being immersed in the water for dipping.
  • a pouch of this kind and having a lid is used in such a manner that, after the inside is filled with liquid via the opening portion of the pouch, a molded piece with a lid is attached by fusion to the opening portion. The lid is attached exclusively for taking out the contents of the pouch, and it is not considered that the liquid or the like is put into the pouch through the lid.
  • the invention has been conducted in view of the above-mentioned circumstances. It is an object of the invention to provide a wide-mouthed pouch which has a small volume in a condition where no contents are included, and which can easily collect sample water or the like in water examination, and also a lid holding member which is suitably used in such a wide-mouthed pouch.
  • the wide-mouthed pouch of the invention is characterized in that the pouch comprises: a bag-like freestanding flexible container formed by joining a plurality of films and having an opening portion at one end; and a lid holding member in which a lid is detachably attached to one end side of a resin molded piece having a substantially cylindrical shape as a whole, and another end side is opened, the pouch is used in a condition where the other end side of the lid holding member is fitted into and attached to the opening portion of the freestanding flexible container in a fluid-tight manner, and a bore diameter of the lid holding member is 35 mm or more (claim 1).
  • the invention has been conducted as a result of intensive study on relationships between procedures of collecting sample water, sample earth and sand, or the like in water examination or the like, and a sampling container used in the examination, and on the treatment of the container.
  • a freestanding flexible container which has a small volume in a condition where contents are not included
  • a structure in which a lid holding member is attached to an opening portion of the freestanding flexible container in a fluid-tight manner so as to facilitate the work of putting the collected sample into the inside is employed, and a bore diameter of the lid holding member is set to be 35 mm or more.
  • a structure is employed in which the lid holding member is fixed to the flexible container in such a manner that a nut-like tightening member is screwed to the lid holding member from the side of the bottom portion of the flexible container in a condition where the lid holding member is inserted into the flexible container, or a band is tightened from the outside in a condition where the lid holding member is inserted into the flexible container.
  • a structure where a groove into which a tightening band is to be fitted is formed on an outer circumference of the side of the lid holding member which is to be inserted into the flexible container may be also employed.
  • the outer circumferential face of the side of the lid holding member which is to be inserted into the flexible container is formed as a tapered face in which the diameter is decreased as moving toward the end side.
  • the invention of claim 6 is an invention relating to a lid holding member which is effectively applied to the wide-mouthed pouch of the invention.
  • FIG. 1 is a perspective view of an embodiment of the invention in a use condition.
  • a freestanding flexible container 1 (hereinafter, referred to as a freestanding pouch 1) has an upper end which is opened.
  • a lid holding member 2 with a detachable lid member 22 is attached in a fluid-tight manner by inserting a main-body portion 21 thereof and tightening a band 3 from the outside of the flexible container 1.
  • Figs. 2 and 3 are front and bottom views of the free-standing pouch 1 in a non-use condition
  • Fig. 4 is a section view taken along the line A-A of Fig. 2.
  • the freestanding pouch 1 has a known structure in which three films 11, 12, and 13 are joined.
  • the two films 11 and 12 constituting a side-wall portion are overlapped, and opposite two sides thereof are joined together to form side joint portions 14a and 14b.
  • both end portions of the other film 13 constituting a bottom member are joined to form three-film joint portions 14c and 14d, in a condition where the film 13 is folded along a fold line 13a formed in a center portion.
  • Both side edge portions of the film 13 for the bottom member are individually joined to base portions of the films 11 and 12, respectively, so as to form bottom joint portions 14e and 14f. Accordingly, a bag-like container which has an opening portion 1a only on an upper side is formed.
  • the fold line 13a of the film 13 constituting the bottom member elongates along the width direction of the films 11 and 12. Accordingly, in a non-use condition, i.e., in a condition where no contents are included, the freestanding pouch 1 takes a sheet-like shape having substantially no thickness by being folded along the fold line 13a as shown in Figs. 2 and 3.
  • the joint portion 14c, 14d, 14e, and 14f between the film 13 for the bottom member and the films 11 and 12 the joint region reaches a higher position as moving toward the right and left sides in a front view.
  • the joint portions 14a to 14f have higher rigidity as compared with the films 11 to 13. For this reason, when the pouch 1 accommodates liquid or a powdery material in the inside thereof, as shown in Fig. 1, the bottom portion is expanded by its own weight, so that the pouch is freestanding.
  • the lid holding member 2 includes the main-body portion 21 and a detachable screw-type lid member 22 which are configured by resin molded pieces, respectively.
  • the main-body portion 21 has a cylindrical shape as a whole, and a male screw 21a for attaching the lid member 22 is formed on an outer circumference on one end side.
  • a flange portion 21b is formed under the male screw 21a at an interval of a predetermined dimen-sion.
  • a groove 21c which elongates in a circumferential direction and into which a band 3 is to be fitted is formed under the flange portion.
  • An outer circumferential face lower than the groove 21c is formed as a tapered face 21d in which the diameter is decreased as moving toward the end side (the lower end side).
  • the bore diameter of a lid-attaching portion of the lid holding member 2 is 35 mm or more.
  • the bore diameter should be set appropriately in accordance with a combination with the capacity of the pouch 1.
  • the bore diameter may be about 35 to 80 mm.
  • the bore diameter may be about 60 to 120 mm.
  • the bore diameter may be about 100 to 120 mm.
  • the reason is as follows. In order to collect water by using a dipper or the like, or to collect water by immersing the pouch into water, a bore diameter of 35 mm or more can facilitate the sampling work. In the case where the pouch 1 having a large capacity is used, however, the volume of the sample water or the like to be contained is increased, and therefore the sampling work should be speedily performed.
  • the outer diameter of the flange portion 21b is larger than the inner diameter of the opening portion 1a of the free-standing pouch 1. In all positions lower than the flange portion, the outer diameter is slightly smaller than the inner diameter of the opening portion 1a.
  • the band 3 is a resin molded product in which a buckle portion 32 is molded integrally with one end of the band main-body portion 31.
  • a product which is commercially available for bundling electric cables or the like is used. Although known in the art, the structure of such a band will be briefly described. A number of ratchet-like teeth are formed on one face of the band main-body portion 31, and a claw which bites the teeth of the band main-body portion 31 is formed on an inner face of the buckle portion 32.
  • the sliding operation can be performed only in a direction in which a loop formed by the band main-body portion 31 becomes small, but cannot be performed in the opposite direction. Therefore, in a condition where the band main-body portion 31 is inserted into the buckle portion 32 to cause the band main-body portion 31 to have a loop shape, and an article is inserted into the loop, when an end of the band main-body portion 31 is pulled, the article is gradually tightened by the band main-body portion 31. The last tightening condition is maintained. The tightening condition is released by cutting the band main-body portion 31.
  • the freestanding pouch 1 and the lid holding member 2 are separately stored, and are integrated by the band 3 as required, immediately before the collection of water at the site or at any timing.
  • the main-body portion 21 of the lid holding member 2 is inserted into the opening portion 1a of the freestanding pouch 1, and the tightening is then performed by the band 3.
  • the work of inserting the lid holding member 2 can be easily performed because the outer circumferential face on the inserting side of the main-body portion 21 is formed as the tapered face 21d.
  • the work is surely performed by inserting the lid holding member 2 until the end of the opening portion 1a abuts against the flange portion 21b.
  • the work of tightening the band 3 can be simply performed by winding the band 3 along the groove 21c formed on the lid holding member 2, and by strongly pulling the end of the band main-body portion 31 after the band main-body portion is inserted into the buckle portion 32.
  • the lid holding member 2 and the freestanding pouch 1 are integrated by externally tightening them by the band 3 in a condition where the lid holding member 2 is inserted into the opening portion 1a of the free-standing pouch 1. Accordingly, for the storage in an unused condition or for the transportation, the freestanding pouch 1 with almost no volume can be separated from the lid holding portion 2 having a short cylindrical shape, so that the required space can be greatly reduced as compared with a wide-mouthed bottle or the like.
  • the bore diameter of the lid holding member 2 is as large as 35 mm or more, the workability for the collection of water or the like in relation to the environmental pollution problem attains the same degree as that of a wide-mouthed bottle which is conventionally used in such a work.
  • the work of integrating the freestanding pouch 1 with the lid holding member 2 can be extremely easily performed. After the use, the pouch 1 and the lid holding member 2 can be easily separated from each other by cutting the band. Therefore, the usage can be realized in which the pouch 1 and the band 3 are disposable, and the lid holding member 2 is recycled.
  • the lid holding member 2 is to be recycled, the washing work is extremely easily performed as compared with a wide-mouthed bottle because the main-body portion 21 has a short cylindrical shape with no bottom.
  • Fig. 6 is a partial longitudinal section view of the lid holding member.
  • a lid holding member 20 in this example includes a main-body portion 201, a screw-type lid member 202 which is detachably attached to the main-body portion 201, and a nut-like tightening member 203 which is similarly detachably attached to the main-body portion 201.
  • the main-body portion 201 has a cylindrical shape as a whole, a male screw 201a is formed on an outer circumferential face on one end side of the main-body portion, and an outer circumferential face on the other end side is formed as a tapered face 201b in which the diameter is decreased as moving toward the end side.
  • the root diameter of the male screw 201a is larger than the maximum diameter of the tapered face 201b. Accordingly, a step portion 201c is formed in a boundary portion between the male screw 201a and the tapered face 201b.
  • the bore diameter and the like are the same as those in the above-described example.
  • the lid member 202 is screwed to the male screw 201a from the upper side of the figure, and the nut-like tightening member 203 is screwed to the male screw 201a from the opposite side.
  • a female screw 203a which is to be screwingly engaged with the male screw 201a is formed on an inner circumferential face on one end side (on an upper side in the figure).
  • An inner circumferential face of the female screw 203a on the lower side is a right circular cylindrical inner face 203b having an inner diameter which is substantially equal to the maximum diameter of the tapered face 201b of the main-body portion 201.
  • a step portion 203c is formed therebetween.
  • the lid holding member 20 is attached to the freestanding pouch 1 as required, for example, immediately before the collection of water or at any timing, as in the above-mentioned example.
  • the usage method including the attaching method will be described below.
  • the main-body portion 201 is inserted into the opening portion 1a of the freestanding pouch 1 from the side of the tapered face 201b.
  • the nut-like tightening member 203 is inserted from the side of the bottom portion. As shown by the two-dot chain line in Fig. 6, in a condition where the freestanding pouch 1 is interposed, the nut-like tightening member 203 is screwed onto the male screw 201a of the main-body portion 201.
  • the step portion 201c of the main-body portion 201 abuts against the step portion 203c of the nut-like tightening portion 203, so that firm tightening can be realized without causing any interference between the nut-like tightening member 203 and the lid member 202.
  • the vicinity of the opening portion 1a of the freestanding pouch 1 is sandwiched between the right circular cylindrical inner face 203b of the nut-like tightening member 203 and the tapered face 201b of the main-body portion 201.
  • the lid holding member 20 is attached to the freestanding pouch 1 in a fluid-tight manner.
  • the contents of the freestanding pouch 1 are discharged, and the nut-like tightening member 203 is then screwed back to be detached from the main-body portion 201.
  • the freestanding pouch 1 is removed from the tapered face 201b of the main-body portion 201.
  • the invention is not limited to the above-described embodiments.
  • a lid holding member having a bore diameter of 35 mm or more is attached to an opening portion of a freestanding flexible container in a fluid-tight manner
  • detailed structures and the like can be arbitrarily configured.
  • the male screw of the main-body portion for screwing the nut-like tightening member may not be continuous to the male screw for attaching the lid member.
  • the lid holding member is integrated with the freestanding flexible container by a band
  • a band of a resin instead of a band of a resin, an article of arbitrary material and shape, such as a metal band having a surface covered with a resin, a strip made of a metal, or a wire-like member can be used, as far as the article has a tightening function.
  • Means such as that for bonding or fusingly attaching the lid holding member to the opening portion of the freestanding flexible container in an unused condition may be employed.
  • an opening portion of a freestanding flexible container constituted by films, and a cylindrical lid holding member having a bore diameter of 35 mm or more are attached in a fluid-tight manner. Therefore, the invention can attain the same degree of workability as that of a conventional wide-mouthed bottle for the purpose of collecting water, earth and sand, dirty soil, or the like in relation to environmental pollution problems. In addition, it is possible to greatly reduce a required space for storage and transportation in an unused condition.
  • a total amount of resins to be used is small as compared with a wide-mouthed bottle, so that the resource saving can be attained. At the same time, since a pouch with superior disposable characteristics is used, the amount of garbage can be largely reduced.
  • a freestanding flexible container and a lid holding member are integrated by inserting and screwing a nut-like tightening member from the side of the bottom portion of the container, or by tightening a band from the outside of the flexible container
  • they can be integrated at an arbitrary timing.
  • the freestanding flexible container is disposable, and the lid holding member can be recycled, so that a great cost reduction can be attained as compared with a wide-mouthed bottle.
  • the cleaning work required for recycling the lid holding member is extremely easily performed as compared with the case where a wide-mouthed bottle is recycled.
