Description

[Technical Field]

[0001] The present invention relates to a spout and a container with a spout. [Background technology]

[0002] Sample collection bags for environmental analysis have also been studied, and some of these collection bags have spouts with extraction tubes (see, for example, Patent Document 1). However, the spouts used in these collection bags must be sealed to allow the sample to be stored after the sample is introduced into the bag.

[0003] To achieve this sealed state, it is necessary to seal the hollow portion of the extraction tube, and conventionally, this has been achieved by providing a plug or the like. If the spout is provided with a means for sealing the extraction tube, sample collection becomes easier. Furthermore, if the sealing means for sample collection can be easily reused, there is an advantage in that costs can be reduced.

[0004] If a two-way or three-way valve is provided to achieve such a sealed state, this increases the cost of the entire container, so it is preferable to separate and reuse the extraction tube portion. As containers with spouts, those described in Patent Documents 2 and 3 are known. [Prior art documents] [Patent documents]

[0011] The present invention will be described in detail below. The present invention provides a spout comprising an adherend and an injection pipe portion, wherein the adherend has a female thread which is a through hole, and the injection pipe portion has a male thread at at least one end thereof and a two-way or three-way valve, and wherein the spout has a structure in which the adherend and the injection pipe portion are integrated by the screw. That is, it is a spout equipped with a two-way or three-way valve, and this two-way or three-way valve is integrated with the adherend by screws, so that after use, the two-way or three-way valve can be easily separated by unscrewing it.

[0012] By using a spout with this structure, a container with a spout can be obtained in the same way as a conventional spout, and the spout valve can be easily removed and reused after use.

[0013] In this case, the female thread is on the adherend side and the male thread is on the dispensing tube side. If this were reversed, the male thread would protrude from the adherend, which would make processing difficult and would require a certain amount of size to be strong.

[0014] An example of a spout of the present invention is shown in Figure 1. The spout of the present invention is formed by combining two parts: an adherend 3 and a pouring member. The pouring member is shown in Figure 2, and the adherend is shown in Figure 3. It is known to form a pouring outlet by providing a male thread on a cap-shaped pouring outlet, having a two-way or three-way valve, and integrating it with a pouring member having a female thread by means of a screw. However, it is not known to provide a male thread on a pouring member as in the present invention.

[0015] When used for purposes such as collecting gas samples, it is preferable to provide a spout with a long, thin tube for ease of operation. The spout of the present invention has been perfected for such purposes and from the viewpoint of reusing the two-way valve or three-way valve. From this viewpoint, in the spout of the present invention, the adherend member is provided with a female thread, and the spout member is provided with a male thread.

[0016] The spout of the present invention also has the advantage that it can be made small. Since it is easy to make a small spout, it can be easily attached to a small container, resulting in a small container that is easy to handle. Even in the case of a large container, a spout of any size can be used as appropriate, making it highly versatile. By adjusting the size of the spout in this way, the spout is less likely to get in the way during actual use, resulting in excellent handleability.

[0017] The dispensing member in Figure 2 comprises an dispensing pipe 1, a two-way or three-way valve 2, and a male screw 4. Dispensing pipe 1 has a hollow shape, through which the sample flows. Also shown in Figure 2 is a two-way valve 2. This two-way valve allows dispensing pipe 1 to be opened and closed. When closed, the inside of the container can be sealed, and when opened, the contents of the container can be taken in from the outside or discharged to the outside through dispensing pipe 1.

[0018] The spout member can be attached to the adherend member 3 by a male screw 4, and by integrating them, a spout as shown in Fig. 1 can be formed. It is preferable to provide a stopper 5 near the male screw. Providing the stopper 5 is preferable because it allows for easy positioning and allows for an optimal positional relationship between the spout and the adherend member when attaching them with the screw.

[0019] The screws in the present disclosure are preferably double-start screws, which allow for efficient attachment.

[0020] The adherend member shown in FIG. 3 serves to adhere the spout to the bag body when forming the container, and there are no particular limitations on its shape as long as it fulfills this role.

[0021] A commonly used example is a columnar molded article having an eye-shaped cross section with an end portion that will become the adherend, as shown in Figure 3. A molded article of this shape can be used by sandwiching both side surfaces of the article between film-like bag-forming materials and adhering them together.

[0022] Furthermore, the adherend has a through hole 6 and a female screw 8 around the hole. It may also have a stopper 7. If the adherend has the stopper 7 and the spout shown in FIG. 2 has the stopper 5, the interaction between these elements allows positioning. In this way, when the spouting pipe is attached, the two-way valve or three-way valve can be positioned in a specific position, and handling is excellent when performing various operations.

[0023] The through-hole 6 is used for the purpose of injecting or discharging substances present in the bag. The substance filled inside is introduced or discharged through this through-hole. The through-hole is preferably formed in the approximate center of the member to be bonded.

[0024] The material of the spout of the present invention is not particularly limited, and can be various resins, metals, etc. Resin is most preferable because it is inexpensive and easy to mold. Furthermore, the adherend and the dispensing tube portion may be made of the same material or different materials.

[0025] The present invention also relates to a spouted container having the spout and bag portion described above. Bag-shaped containers with spouts are well known, and in the present invention, a spouted container can be obtained using the spout described above and a well-known method using a well-known material.

[0026] The spouted container of the present invention may be provided in a cutout formed in the film. One such spout may be provided in one container, or two or more spouts may be provided in one container. Examples of such containers are shown in FIGS.

[0027] The spout-equipped container of the present invention is a container having a spout, which is obtained by sandwiching and bonding both sides of the above-mentioned spout-to-be-bonded member between the film substrates constituting the container. The method for bonding the film substrate and the spout here is not particularly limited, and examples include bonding with an adhesive, heat-sealing bonding, etc.

[0028] The film substrate is not particularly limited, and polyolefin resin film, biaxially oriented polyethylene terephthalate resin film, fluororesin film, etc. can be used. Furthermore, it may be a multilayer film or a laminate having an aluminum vapor deposition layer. The bag can be formed by any known method such as heat sealing or bonding with an adhesive.

[0029] The spouted container of the present invention is not particularly limited in its use, and can be used, for example, as a sample collection bag for use in environmental analysis. Sample collection bags for environmental analysis require the bag to be sealed after the sample is introduced into the bag. When using the spouted container of the present invention, the two-way or three-way valve is opened to collect the sample, and then the two-way or three-way valve is closed. In this closed state, the collection bag is moved to the location of the measuring device, and when measurement is to be performed using the measuring device, the two-way or three-way valve can be opened to introduce the sample into the measuring device.

[0030] The spouted container of the present invention is not particularly limited in the materials it can contain, and examples of such materials include gases, liquids, semi-solids, powders, etc. In other words, it can be particularly suitably used as a collection bag for samples that contain gases or liquids in part, in addition to gas samples.

[0031] The spouted container of the present invention may have two or more spouts formed by the spouts of the present invention, as shown in Figures 5 to 7. When used as a gas sample collection bag, this is preferable because the inside of the bag can be completely replaced with the sample to be measured by introducing gas from one spout and discharging it from the other spout.

[0032] Furthermore, when used as a sample collection bag for liquid or slurry samples, it is preferable that when introducing the sample through one port, the inside of the collection bag is opened to efficiently discharge the air inside the bag, thereby enabling efficient sample collection. Also, when discharging, by introducing gas through one port and discharging it through the other port, the sample can be discharged under pressure, which is preferable in that the sample can be discharged efficiently.

[0033] When used as various packaging containers, the contents can be removed simultaneously from multiple outlets, which is advantageous in that the contents can be continuously supplied to multiple lines depending on the usage situation. [Industrial Applicability]

[0034] The spout of the present invention can be suitably used in sample collection bags used in environmental analysis, food packaging containers, and other packaging containers in the industrial field. [Explanation of symbols]
