Description

  The present invention relates to a container with a spout in which, for example, a spout for taking in and out a stored item is attached to an opening of a container made of synthetic resin.

  2. Description of the Related Art Conventionally, there is known a spout-equipped container in which a spout is attached to a container formed of a relatively flexible material such as a synthetic resin sheet in order to take out the contents contained therein. This spout is usually integrally formed with a synthetic resin or the like, and is disposed between the above-described synthetic resin sheets and is sandwiched by heat welding. Such a spout-equipped container is used in various fields, and various configurations of spouts have been developed accordingly.

  For example, as a usage mode of a container with a spout, there is one in which a sucking needle is inserted into a mouth part of a spout to pour out a stored material and supply this to a necessary place. In this case, an elastic body (rubber) into which the needle is inserted is sealed in the mouth portion of the spout so as to seal the contents and to be used a plurality of times.

  By the way, in such a configuration, the elastic body must have a considerably strong pressing force toward the central region where the needle is inserted. That is, if this pressing force is weak, there will be a gap between the inserted needle and the elastic body, or after the needle is pulled out, the trace of the needle will remain and a passage will be created, This is because things are likely to leak out.

  In order to solve such a problem, Patent Document 1 discloses a division in which an accommodation part for accommodating an elastic body is formed in a welding part to which a synthetic resin sheet is welded, and the welding part can be opened and closed via a hinge. The spout which provides a pressing force to an elastic body by providing a part and closing a division | segmentation part in the state which accommodated the elastic body in the said accommodating part is disclosed.

Further, in the patent application 2 which is the previous application, the present applicant has formed a housing portion in which an elastic body is enclosed in the communication hole portion of the spout body, and screwed the female screw portion formed in the communication hole. The structure which gives a pressing force to an elastic body by screwing is proposed.
JP 2003-104402 A Japanese Patent Application No. 2004-190599

  According to the known technique disclosed in Patent Document 1 described above, a spout-equipped container is obtained with a simple configuration that applies a pressing force toward the center to the elastic body.

  However, since the mouth part (plug part) which protrudes upwards is formed in the main body to which the synthetic resin sheet is welded, when viewed as the entire container, the body is enlarged in the vertical direction. For example, such a container is installed in a predetermined rigid case, this case is attached to a dispensing needle portion provided in an external device, and the dispensing needle is inserted into the mouth portion to contain the container. In such a configuration, it is necessary to form a holding portion for holding the mouth portion in the case, so that a dead space is generated by the amount of protrusion of the mouth portion, and the amount of stored items is reduced. There is a problem that it ends up. Further, since the projecting mouth portion exists, the case-side mounting structure becomes complicated, and accordingly, there is a problem that the mounting position is difficult to be flexibly adapted according to the request of the external device.

  Moreover, according to the container with a spout proposed in Patent Document 2 described above, a screw is screwed and sealed so as to be substantially flush with the upper surface of the spout body without forming a protruding mouth portion. Since the pressing force is applied to the elastic body, the above-mentioned problems are solved. It seems that there is room for improvement in terms of twisting the body and giving a uniform pressing force.

  The present invention has been made based on the above-described problem, and in a spout-equipped container enclosing an elastic body, it is possible to increase the capacity of the accommodated object and to accommodate the spout. It aims at providing the container with a spout which can attain simplification of the attachment structure in the case where is installed. Another object of the present invention is to provide a structure with which a spout-equipped housing as described above can easily incorporate an elastic body and applies a uniform pressing force to the enclosed elastic body. And

  In order to solve the above-described problem, the container with spout according to claim 1 is formed by forming a container with a plurality of sheet materials, and the spout is welded between the plurality of sheet materials. A pair of welding surfaces to which the sheet material is welded, a substantially flat exposed surface, a communication hole extending along the pouring direction, and an accommodating portion for accommodating an elastic body in an intermediate portion of the communication hole are formed. The inner wall defining the communication hole is formed with a flange projecting toward the center. The flange is pressed against the elastic body and substantially flush with the exposed surface. The lid member to become is locked.

  In the container with a spout having the above-described configuration, the upper surface side (exposed surface side) of the spout is formed to be substantially flat, and when the lid member is locked to the flange, the lid member and the exposed surface are substantially flush with each other. Since the protruding portion such as the mouth portion is not formed, for example, when installing a spouted container in a predetermined case, there is a dead space in the case corresponding to the protruding amount of the mouth portion. No longer occurs. That is, it is possible to configure the container up to the height position of the exposed surface of the spout and prevent the dead space from being generated in the case. There is no need to provide a mounting portion for holding and guiding the protruding mouth portion in the case, and the configuration of the mounting portion in the case is simplified. Therefore, according to the request | requirement of the external apparatus with which the said case is mounted | worn, the position change of the mounting part of the case with a spout can be easily performed, and it becomes possible to respond flexibly.

  Further, by pushing the lid member and locking it to the flange of the main body of the spout, the elastic body is pressed by the lid member, and a pressing force acts from the inner wall of the housing portion. For this reason, the work of assembling the elastic body can be easily performed.

  In the above-described configuration, the “substantially flat” of the exposed surface and the “substantially flat” of the lid member include those formed in a strictly horizontal state. It may be configured such that there is a slight unevenness in the portion where is attached. Further, the flanges are formed at predetermined intervals (for example, three positions at predetermined intervals) along the inner wall that defines the communication hole. Alternatively, it may be formed continuously over the inner wall.

  The invention according to claim 2 is characterized in that a groove is formed around the communication hole of the main body.

  By forming such a groove portion, when the lid member is locked to the flange in the communication hole, the groove portion can escape and elastically deform, and the lid member can be easily engaged with the flange. It is possible to stop.

  The invention according to claim 3 is characterized in that a support portion for supporting an enclosed elastic body is formed in the housing portion.

  In such a configuration, the support state of the elastic body in the accommodating portion is stabilized, and when the lid member is locked to the flange, it is possible to apply the pressing force uniformly without the elastic body falling.

  Moreover, in the invention which concerns on Claim 4, while forming the thin thickness part in the said cover member, forming the sealing wall which seals the said accommodating part between the internal spaces of the accommodating body in the said communicating hole. Features.

  In such a configuration, it is possible to prevent dust and the like from adhering to the elastic body from the lid member, and it is possible to prevent the container from coming into contact with the elastic body from the container body side.

  The invention according to claim 5 is characterized in that a hole for holding the main body is formed in the exposed surface when the plurality of sheet materials are welded.

  According to such a configuration, the spout containing the elastic body can stably hold the state by simply inserting the hole formed in the exposed surface of the main body into the jig, and easily It becomes possible to weld the sheet material to the welding surface. In addition, the hole formed on the exposed surface of the spout as described above is provided with a pin on the case side when the spouted container is installed in the case, and the hole of the spout is provided on this pin. By inserting it, it becomes possible to use it in a stable state without moving the container with spout.

  Moreover, in the container with a spout according to claim 6, in the configuration in which the container is formed by a plurality of sheet materials and the spout is welded between the plurality of sheet materials, the sheet material is welded to the spout. It has a main body formed with a pair of welding surfaces, a communication hole extending along the pouring direction, and an accommodating portion for accommodating an elastic body in an intermediate portion of the communication hole, and defines the communication hole A flange protruding toward the center is formed on the inner wall, and a lid member that presses the elastic body is pressed and locked to the flange along the dispensing direction.

  In the container with spout having the above-described configuration, the lid member is locked to the flange, whereby the elastic body is pressed by the lid member, and a pressing force acts from the inner wall of the storage portion. Further, since the pressing force acts on the elastic body only by performing the pressing operation so that the lid member is locked to the flange, the operation at the time of assembly can be easily performed.

  According to the container with a spout of the present invention, it is possible to increase the amount of accommodation of the container and to simplify the configuration of the mounting portion of the case to which such a container with the spout is attached. It becomes.

  Moreover, according to the container with a spout of the present invention, the elastic body can be easily assembled and a uniform pressing force can be applied to the sealed elastic body.

FIG.

  The spout-equipped container 1 according to the present embodiment prepares a plurality of sheet materials 2a, for example, a plurality of flexible synthetic resin sheets that are relatively inexpensive materials, and arranges them facing each other to indicate a region indicated by grid-like diagonal lines. The container 2 is configured by heat welding and a spout 10 sandwiched (heat-welded) between sheet materials at the upper end portion.

  The spout 10 includes a main body 12 having a pair of welding surfaces 11 to which the opposing sheet material 2 a is welded. The main body 12 has a substantially boat-shaped cross section so that the sheet material can be easily welded to the welding surfaces 11. It is formed to have a shape. In addition, about the shape of the welding surface 11, it can deform | transform suitably, such as forming with a flat surface or comprising with a curved surface.

  A communication hole 13 extending in the vertical direction (pouring direction) is formed in the central portion of the main body 12. The communication hole 13 is used to take out the contents stored in the container. As will be described later, a dispensing needle is inserted into the communication hole 13 and receives a suction action. The contents are taken out.

  An accommodating portion 15 is formed at an intermediate portion of the communication hole 13 so that a spherical elastic body 50 (rubber) is accommodated. The elastic body 50 is sealed from an opening portion of the communication hole 13. It is like that. The accommodating portion 15 includes an inner peripheral surface 15a extending substantially along the dispensing direction, and the inner peripheral surface 15a is poured by the elastic body 50 by attaching a lid member, as will be described later. When pressed along the exit direction, a pressing force toward the center is applied to the elastic body.

  In the center of the bottom surface 15 b of the housing portion 15, a housing body side communication hole 13 a connected to the communication hole 13 and connected to the internal space of the housing body 2 is formed. In this case, the bottom surface 15b may receive the elastic body 50 accommodated by a flat surface. However, as shown in FIGS. 3 and 4, the bottom surface 15b has a predetermined interval (120 in the configuration shown in the figure). It is preferable to support by support portions 16 formed at intervals of °. The support portion 16 is formed with a curved support surface 16a that receives the spherical elastic body 50 by the surface, and the support state of the elastic body 50 is stabilized by supporting the curved support surface 16a at three locations. I can plan.

  A pressing lid member 30 is fitted into the communication hole 13 along the extending direction of the communication hole 13, and the elastic body 50 is pressed by inserting the lid member 30. In addition, a predetermined pressing force is applied to the elastic body 50 from the inner peripheral surface 15 a of the housing portion 15.

  A flange 17 that protrudes toward the center is formed at a position above the accommodating portion 15 of the inner wall that defines the communication hole 13 so that the lid member 30 is locked when the lid member 30 is fitted. ing. In this embodiment, three flanges 17 are formed at intervals of 120 ° along the inner wall, and a lid member 30 is fitted to each flange 17 toward the communication hole 13 as shown in FIG. An inclined portion 17a that smoothly guides the lid member 30 when being inserted is formed.

  On the other hand, the lid member 30 is formed with a flange-like locking portion 31 over the outer peripheral surface thereof, and the locking member 31 has a lid member along the inclined portion 17 a formed on the flange 17. An inclined portion 31a that facilitates the fitting of 30 is formed. In addition, the lid member 30 is formed with a hole 32 into which a dispensing needle is inserted at the center thereof.

  The hole 32 formed in the lid member 30 is preferably formed with a thin film member 32a so that dust or the like does not adhere to the elastic body 50. In addition, it is preferable that a thin-walled film member 13b is also formed in the container-side communication hole 13a so that an object is not attached to the elastic body 50.

  A pressure contact surface 33 is formed on the back surface of the lid member 30 so as to be in pressure contact with the elastic body 50 sealed in the accommodating portion 15. In the present embodiment, the pressure contact surface 33 is formed in a flat shape, and the elastic member 50 is pressed against the elastic body 50 in a state where the lid member 30 is fitted and the locking portion 31 is locked to the flange 17. A uniform pressing force acts downwardly from the surface 33 reliably, and as a result, a pressing force directed from the inner peripheral surface 15a toward the center acts.

  The main body 12 of the spout of the present embodiment is formed so that the upper surface side (exposed surface 27) is substantially flat. Further, the lid member 30 has a gap between the lid member 30 and the flange 17. When the predetermined pressing force is applied to the elastic body 50 in the locked state, the exposed surface 27 and the exposed surface 27 are substantially flush with each other.

  Moreover, it is preferable to form a circumferential groove 19 around the communication hole 13 in the main body 12 of the spout 10. That is, by forming such a groove portion 19, when the lid member 30 is fitted into the communication hole 13, the flange 17 portion can be deformed radially outward, and the lid member 30 can be easily connected to the communication hole. 13 can be inserted. Such a groove portion 19 can be appropriately modified with respect to its shape, such as being formed corresponding to the position where the flange 17 is formed.

  As described above, in the configuration of the present embodiment, when the lid member 30 is inserted into the main body 12 of the spout, the projecting mouth portion or the like is not formed on the exposed surface 27 of the main body 12. When the material 2a is welded to the welding surface 11, a hole 34 into which a jig 60 (see FIG. 6) configured in a pin shape is inserted into the main body 12 so that the welding operation can be performed easily and stably. Is formed. The holes 34 of the present embodiment are formed on both sides of the lid member 30 and are configured to be stably held when inserted into the pair of jigs 60. In other words, the spout 10 is manually inserted into the jig 60, or is guided to a welding portion of a welding apparatus (not shown) after the mechanical insertion process, and the two parts shown in FIG. As shown by the dotted line, the spout-equipped container is created by thermally welding the sheet material 2 a to each welding surface 11.

  The spout 10 configured as described above and the lid member 30 fitted into the communication hole 13 can be integrally formed by molding a synthetic resin.

  According to the spout 10 having the above-described configuration, the spherical elastic body 50 is sealed from the opening portion of the communication hole 13 along the extraction direction before the sheet material 2a serving as the container is welded, and the container 15 (support After the elastic body 50 is held on the surface 16 a), the lid member 30 is fitted into the communication hole 13. At this time, the locking portion 31 of the lid member 30 can be easily fitted by the inclined portion 31 a being guided by the inclined portion 17 a formed on the flange 17 and the flange portion being deformed by the groove portion 19. .

  When the locking portion 31 of the lid member 30 is locked to the flange 17, the pressure contact surface 33 of the lid member abuts on the elastic body 50 held in the housing portion 15 to force the elastic body 50. It is pressed (compressed) to be elastically deformed. In this case, since the lid member 30 is press-fitted along the dispensing direction, no twisting rotational force acts on the elastic body 50, and the elastic body 50 has three support surfaces. Since it is supported by 16a, no twisting force is applied. As a result, the elastic body 50 is maintained in a stable support state, and can apply a uniform and reliable pressing force from the inner peripheral surface 15a of the housing portion 15 toward the center.

  Then, as shown in FIG. 6, the spout 10 configured as described above is simply inserted into the jig 60 with the hole portion 34 formed in the exposed surface 27 of the main body 12 as described above. Since it can hold | maintain stably, it becomes possible to weld the sheet | seat material 2a to the welding surface 11 easily.

  It should be noted that the container to be accommodated in the container 2 is filled with the end portion of the overlapped sheet material 2a without being welded, and then the unwelded portion is welded to the final product. A spouted container is completed. Alternatively, a spout-equipped container that is the final product is completed by inserting a filling needle into the elastic body 50 and filling the accommodated object with the spout-equipped container that does not contain the contents. In the latter case, the elastic body 50 is applied with a pressing force toward the central region where the needle is inserted depending on the shape of the accommodating portion 15, so that there is a gap between the inserted needle and the elastic body 50. It does not occur, and even after the needle is pulled out, a pressing force acts to block the passage, so that leakage of the contents is prevented.

  Moreover, in the container with a spout having the above-described structure, the main body 12 of the spout 10 is formed so that the exposed surface 27 side is substantially flat, and no protruding portion such as a mouth is formed. When the spouted container is installed in the case, the dead space is not generated in the case by the amount of protrusion of the mouth. That is, since the container can be configured up to the height position of the exposed surface of the spout and no dead space can be generated in the case, it is possible to secure the maximum amount of the stored item. Accordingly, the configuration of the portion of the case portion that holds the spout-equipped container is also simplified, so that the position can be easily changed according to the requirements of the external device. For this reason, the spout 10 can be variously changed according to the request of the external device, such as welding to the side part of the sheet member or welding to the corner part.

  And in the container with a spout comprised as mentioned above, the container in the container 2 inserts the needle | hook for extraction into the thin thickness part 32a currently formed in the above-mentioned cover member 30, and is an elastic body. It is poured out by sucking through 50. That is, since the surface portion of the lid member 30 is formed to be thin and thick, the dispensing needle can be easily inserted.

  Although the embodiment of the present invention has been described above, the present invention can be variously modified as follows, for example, in addition to the above-described embodiment.

  The container 15 having the above-described configuration may be configured to press the sealed elastic body 50 toward the center direction in which the needle is inserted. The pressing method for the body can be modified as appropriate. Further, the position where the flange 17 is formed, the structure of the locking portion 31 of the lid member 30 locked to the flange 17, the locking structure of both, the shape of the elastic body 50 and the accommodating portion 15 to be sealed, and the lid member The shape of the 30 pressure contact portions can be appropriately modified as long as the elastic body 50 is pressed toward the central direction when the lid member is press-fitted in the communication hole direction. Further, the lid member 30 may be configured to slightly protrude from the exposed surface of the main body 12.
