  For example, in Patent Document 1, a protrusion formed on the bottom surface of the container body by allowing the sprue portion to remain during molding is inserted into a shaft hole provided in a hanging tool, and then the tip of the protrusion is melted to expand the diameter. And the technique of latching a suspension tool by the formed enlarged diameter part is disclosed.

Japanese Patent Laid-Open No. 10-291541

  However, the technique described in Patent Document 1 requires a hanging tool having a complicated structure. In addition, when a container with a hanging tool is hung upside down, the load of the container main body filled with a chemical solution or the like is concentrated on the enlarged diameter portion, which destroys the enlarged diameter portion, and the container is removed from the hanging tool. The body may fall off. Therefore, in order to increase the strength of the enlarged diameter part, if the tip of the above-mentioned protrusion for forming the enlarged diameter part is thickened, the shape of the preform is specialized, and the temperature distribution of the preform is biased and the container after blow molding This leads to a new problem of variation in the wall thickness.

  The present invention has been made in view of the above-described circumstances, and the object of the present invention is to provide a suspension-equipped container that can improve the suspension strength while allowing the suspension to have a simple structure and can be easily implemented. It is in providing a manufacturing method and a container with a hanging tool.

In order to achieve the above object, a method for manufacturing a container with a lifting device according to the present invention is configured such that the mounting base portion of the lifting device provided with a hinge portion between the mounting base portion and the main body portion is used as the bottom portion of the container body. A method of manufacturing a container with a hanging tool that is joined to the meat pool part from the outside of the container body , wherein the hanging tool has a plurality of mounting bases, and each mounting base is a peripheral part of the meat pool part. bonded to (claim 1).

Further, in the above manufacturing method, the bottom portion of the container body is provided with an immersive portion that is immersed inside the container main body with respect to the other portion of the bottom portion, with respect to the meat reservoir portion that constitutes the immersive portion. The attachment base portion of the lifting tool may be joined (Claim 2 ).

On the other hand, in order to achieve the above object, a container with a hanger according to the present invention comprises a container main body having a meat reservoir portion formed at the bottom, and a hanger having an attachment base joined to the outside of the meat reservoir portion. A container with a suspension provided with a hinge between the attachment base and the main body of the suspension, the suspension having a plurality of attachment bases, each attachment base Are joined to the peripheral edge of the meat reservoir (claim 3 ).

Further, in the container with a lifting tool, a bottom portion of the container main body is provided with an immersive portion that is immersed inside the container main body more than other portions of the bottom portion, and the meat pool portion that constitutes the immersive portion On the other hand, the attachment base part of the said lifting tool may be joined (Claim 4 ).

In the invention which concerns on Claims 1-4 , the manufacturing method of the container with a hanger and the container with a hanger which can aim at improvement of hanging strength, and can carry out easily, giving a hanger a simple structure. can get.

That is, in the inventions according to claims 1 to 4 , the hanger is joined to the reservoir portion of the container body, and the thickness of the reservoir portion is relatively large. The possibility of breakage or the like is extremely low, and severe control or the like is not required for the joining operation. Therefore, the manufacture of a container with a hanging tool can be performed easily.

  In addition, since the hanging tool is attached using the thick-walled portion, the performance such as the hanging strength and durability of the container with the lifting tool can be improved. Moreover, since the meat pool part (immersion part) used for joining usually occupies a relatively large area at the bottom part, it is easy to increase the joining area of the hanger to the meat pool part. In addition, it is possible to improve the hanging strength and the like, and an increase in the bonding area does not cause a new problem.

  Furthermore, when manufacturing a container with a hanging tool, a conventional blow-molded container can be used as it is for the container body, and the only component other than the container body is the hanging tool. And this hanging tool should just be joined to the meat pool part of a container main part, and it is not necessary to give a complicated structure, and since the composition can be made very simple, a container with a lifting tool The manufacturing cost can be very inexpensive as a whole.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  A container with a lifting tool (hereinafter abbreviated as “container”) 1 according to the present embodiment has a symmetrical shape in front, rear, left and right, and is shown in FIGS. 1 (A) to 1 (C) and FIG. 2 (B). Thus, the container main body 3 in which the meat pool part 2 was formed in the bottom part and the hanger 4 joined to the outer side of the meat pool part 2 are provided (refer also FIG. 3).

  The container body 3 is a self-supporting resin container formed by biaxial stretch blow molding, for example, and has a symmetrical shape in the front, rear, left, and right. In this example, the container 1 is an infusion bottle, and the container body 3 contains contents such as a chemical solution.

  As shown in FIGS. 1 (A) and 1 (B) and FIGS. 2 (A) and (B), a mouth portion 5 is provided on the upper portion of the container body 3, and the mouth portion 5 has a cover with a lead-out port. (Not shown) is attached, and an infusion tube (not shown) is connected to the outlet of the lid.

  The cross section of the body portion 6 of the container body 3 has a substantially elliptical shape in which the front-rear width is smaller than the left-right width, and the contents of the container 1 are led out from the mouth portion 5 when the container 1 is suspended upside down. Accordingly, the body portion 6 is deflated so as to shrink mainly in the front-rear direction.

  As shown in FIGS. 1 (A) to 1 (C) and FIG. 2 (B), the bottom 7 of the container body 3 is located on the inner side of the container body 3 (the container 1 is in an upright posture) as compared with the other parts of the bottom 7. In this case, an immersive portion 8 that is immersive (indented) is provided on the upper side. The bottom portion 7 provided with the immersive portion 8 has unevenness (or ribs) for improving the rigidity of the bottom portion 7, and the container 1 is hung on the hook 4 (not shown). When the is suspended upside down, the bottom 7 hardly deforms.

  Here, as shown in FIG. 1 (C), a bottom surface of the bottom portion 7 is formed with a grounding surface (grounding circle) 7a that is grounded in a substantially annular shape when the container 1 is in an upright posture. As viewed, an immersion portion 8 is provided on the inner peripheral side of the ground surface 7a (so as to be surrounded by the ground surface 7a). And this immersion part 8 is comprised by the meat pool part 2, as shown to FIG. 1 (A). That is, as shown to FIG. 1 (A) and (C), the site | part corresponded to the immersive part 8 is the thickened part 2 thicker than another site | part among the bottom walls which comprise the bottom part 7. FIG. .

  On the other hand, as for the hanger 4, the attachment base part 9 is joined with respect to the meat pool part 2 which comprises the immersion part 8, and, thereby, the container 1 is obtained.

  Here, as shown in FIG. 3, the hanger 4 includes a substantially U-shaped main body 10, two mounting bases 9 provided at both ends of the main body 10, and each mounting base 9 and main body. The main body 10 can be raised and lowered with the two hinges 11 as an axis.

  In this example, between the attachment base portion 9 and the main body portion 10, a portion that is thinner (thinner) than these portions 9 and 10 is formed, and the portion is used as the hinge portion 11. For example, a bent portion may be provided between the mounting base portion 9 and the main body portion 10, and this bent portion may be used as the hinge portion 11.

  And the main body part 10 (see the phantom line in FIG. 1B) lying down via the hinge part 11 is placed inside the container main body 3 (the container 1 is in an upright posture) than the grounding surface 7a of the bottom part 7. In this state, when the container main body 3 is placed in an upright posture, only the grounding surface 7a is grounded, and the hanger 4 (main body portion 10) is not grounded. Be independent with good stability. Further, the main body portion 10 (see the solid line in FIG. 1B) standing up via the hinge portion 11 is outside the container main body 3 than the grounding surface 7a of the bottom portion 7 (when the container 1 is in an upright posture). And the hook 1 and the like can be easily hooked, so that the operation of hanging the container 1 upside down can be facilitated by placing the main body 10 upright as described above. Become.

  Moreover, as a method of joining the attachment base 9 of the hanger 4 to the meat reservoir portion 2 of the container body 3, for example, adhesion using a resin adhesive, an adhesive fiber, or the like in addition to welding such as thermal welding or ultrasonic welding. Can be mentioned. If the joining method is welding, the hanging tool 4 is the same as the container body 3 in terms of welding either one or both of the base 9 and the meat pool portion 2 of the hanging tool 4 or both. It is preferable to mold from a homogeneous material. However, the case where the above-described joining is performed by adhesion is not limited thereto.

  In the case of performing the above-mentioned welding, for example, a method of melting and joining the base material (base portion 9 and the pool portion 2) by heating, microwave, electricity, ultrasonic vibration and pressure, etc. may be adopted. it can. Examples of the resin adhesive include cyanoacrylate adhesives such as Aron Alpha (registered trademark) and epoxy adhesives such as Araldite (registered trademark).

  In this example, the hanger 4 is joined to the immersive portion 8 that has a substantially elliptical shape that is horizontally long when viewed from the bottom so that the center is overlapped along the long axis (particularly FIG. 1). (See (C)).

  The material of the container body 3 and the hanger 4 may be appropriately selected according to the use of the container 1, the joining method, the molding method of the members 3 and 4, and the like. For example, various thermoplastic resins can be used. More specifically, thermoplastic polyester resins such as polypropylene, polyethylene (high density, low density, linear low density), polyethylene terephthalate (PET), polybutylene terephthalate, polyarylate, polyamide (nylon) resin, poly It can be vinyl chloride or the like.

  As described above, the container 1 of the present embodiment is obtained by joining the hanger 4 to the meat pool portion 2 of the container body 3, and the thickness of the meat pool portion 2 is relatively large. Accordingly, the possibility of pinholes, breakage, etc. occurring in the meat pool portion 2 is extremely low, and severe control or the like is not required for the joining operation. Therefore, the manufacture of the container 1 can be performed easily.

  Moreover, since the hanging tool 4 is attached using the thick-walled portion 2 having a large thickness, the performance such as the suspension strength and durability of the container 1 can be improved. Moreover, since the meat reservoir portion 2 (immersion portion 8) used for joining normally occupies a relatively large area in the bottom portion 7, it is easy to increase the joining area of the hanger 4 to the meat reservoir portion 2. As a result, the suspension strength and the like can be improved, and an increase in the bonding area does not cause a new problem.

  Furthermore, in manufacturing the container 1, a conventional blow-molded container can be used as it is for the container body 3, and the constituent members other than the container body 3 are only the hanger 4 having a very simple structure. The manufacturing cost of the container 1 can be made very inexpensive.

  In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.

  The container body 3 is not limited to the shape shown in FIGS. 1A to 1C, and may have a shape suitable for the use of the container 1 such as a square shape or a round shape. And the molding method of the container main body 3 should just form the pool part 2 in the bottom part 7, and may be molding methods other than blow molding.

  In the above embodiment, the hanger 4 is joined along the long axis to the immersive portion 8 having a substantially elliptical shape when viewed from the bottom (see FIG. 1C). As shown in FIG. 4, the hanger 4 may be joined to the immersive portion 8 along the short axis. Moreover, the center of the hanger 4 and the center of the immersive part 8 do not need to overlap in bottom view.

  Here, the immersive portion 8 shown in FIGS. 1C and 4 has a substantially elliptical shape when viewed from the bottom, but the shape of the immersive portion 8 may be other shapes, The shape and size of the hanger 4 and the joining position with respect to the immersive portion 8 may be appropriately determined according to the shape of the portion 8.

  Similarly, the grounding surface (grounding circle) 7a of the bottom 7 is not limited to an annular shape, and may be, for example, a shape in which the annular shape is intermittent (partially interrupted).

  Also, the configuration of the hanging tool 4 can be variously modified. For example, as shown in FIG. 5, two hanging tools 4 are provided side by side, and each main body 10 is configured to lie on the opposite side. There may be.

  3 has two attachment bases 9 and two hinge parts 11, respectively, but the suspension 4 has three attachment bases 9 and three hinge parts 11 as shown in FIG. You may have, and you may have four or more.

  In each of the above-described modifications, the hanging tool 4 has a plurality of attachment bases 9 and each attachment base 9 is joined to the meat accumulation portion 2. As shown in FIG. 9 may be provided, and in this case, the main body 10 may be formed in an annular shape, for example.

  Further, as shown in FIG. 8, the hanger 4 may be formed in a substantially annular shape, and one side thereof may be used as the attachment base 9, and in this case, a hinge portion is provided between both ends of the attachment base 9 and the main body 10. 11 may be formed.

  The attachment base 9 of the hanger 4 only needs to have a structure suitable for joining to the meat pool portion 2, and the main body 10 only needs to have a structure suitable for hooking on a hook or the like. The portion 11 only needs to have a structure that allows the main body portion 10 to be raised and lowered, and the shapes described above are examples of a handful of shapes that can be given to each. It is only an indication.

  If the container 1 is not required to be self-supporting, the hinge portion 11 may not be provided, and only the state where the main body portion 10 stands up may be taken.

  Here, when the container body 3 is formed by blow molding, a sprue (gate protrusion) 12 is formed on the bottom surface of the container body 3 as shown in FIGS. 6 and 7 (in drawings other than FIGS. 6 and 7). The illustration of the sprue 12 is omitted). Therefore, when the hanger 4 has the attachment base 9 at a position corresponding to the sprue 12 (for example, when the hanger 4 is configured as shown in FIG. 6 or FIG. 7), the attachment base 9 is attached to the sprue. You may join to the meat pool part 2 via 12.

  Needless to say, the modifications described in the embodiment and after the description may be combined as appropriate.
