And the upper end opening is shaped so as to have a circular opening shape, and the upper end opening is deformed so as to have an elliptical or oval opening shape, and a peripheral portion of the upper end opening is By providing a pump with a container which is locked to the peripheral portion of the lower end having an elliptical or oval opening shape of loaders, in which to achieve the above objects.

  According to the container with a pump having a container body made of a flexible material according to the present invention, the container body is prevented from being deformed by a gripping force when the container is gripped and the pumping operation is performed, and a stable pumping operation is performed. It can be performed smoothly and the appearance can be prevented from being damaged.

  Hereinafter, a preferred embodiment of the pump-equipped container of the present invention will be described with reference to the drawings. The container 10 with a pump of this embodiment shown in FIGS. 1 to 4 is a double-type discharge container provided with a pair of tube-shaped container bodies 11 (see FIG. 2), and the contents include, for example, a two-agent type dyeing Two types of agents such as hair agents are simultaneously taken out from the container body 11 by a single pumping operation, and can be discharged from the discharge port 14a of the nozzle unit 14 in a state where these agents are mixed. It has become.

  In the container 10 with a pump according to the present embodiment, a pumping operation is performed while gripping the upper part of the container 10 by using the lever 6 rotatably attached to the holder 5 that holds the pair of container main bodies 11 in a juxtaposed manner. However, it is possible to prevent the container body 11 made of a flexible material from being deformed by the gripping force when performing the pumping operation, and to perform a stable pumping operation smoothly. In addition, it has a function of preventing the appearance from being damaged by the deformation of the container body 11.

  And the container 10 with a pump of this embodiment consists of a material which has flexibility, the cylindrical container main body 11 with which the one end part 11a on the opposite side to the opening part 11b was obstruct | occluded, and the opening part of the container main body 11 A pump device 13 having a pump body 15 and a nozzle portion 14 mounted on 11b; a holder 5 that covers the pump device 13 and is attached to the container body 11 and includes a lever 6 as a pumping means for operating the pump device 13; A bottomed cylindrical cover body 30 that covers the accommodating portion 11d of the container main body 11 and is attached to the holder 5 by locking the peripheral portion of the upper end opening 30a to the peripheral portion of the lower end opening 5a of the holder 5. Is done.

  In the present embodiment, the lever 6 as the pumping means is rotatably attached to the holder 5, and the operation part 6 </ b> C extends to the side of the container body 11, and the operation part 6 </ b> C is connected to the container body 11. When the pump device 13 is operated so as to be close to the nozzle, the contents are discharged from the discharge port 14a of the nozzle portion 14.

  Furthermore, in the present embodiment, the holder 5 is a dual-type holder that holds the pair of container main bodies 11 in a state of being arranged side by side and simultaneously discharges the contents from each container main body 11 by operating the lever 6. A pair of container main bodies 11 are juxtaposed and attached to this double holder 5.

  In the present embodiment, the container body 11 constituting the pump-equipped container 10 is made of a flexible material, and as shown in FIG. 2, a tubular shape in which one end portion 11a opposite to the mouth portion 11b is closed. It is a cylindrical body. The container body 11 is formed in a cylindrical shape having an inner diameter of about 10 to 50 mm and a height (length) of about 70 to 200 mm, for example.

  The container body 11 contains, for example, two-component contents (not shown) such as a hair dye and a toothpaste. The contents in this embodiment are a first agent and a second agent of a two-component hair dye. The contents stored in the container main body 11 are sucked by the pump action of the pump device 13 (see FIG. 5) and discharged from the discharge port 14a through the nozzle portion 14.

In the case where the contents are deteriorated by oxygen (for example, a hair dye), the container body 11 is preferably made of a sheet material having an oxygen barrier property in order to prevent deterioration of the contents. As such a sheet material, for example, an aluminum laminate resin can be cited.
The one end 11a of the container body 11 is closed as follows, for example. First, the pump device 13 is fixed to the mouth portion 11b. In accordance with a conventional method for forming a tube container with a pump, the container body 11 is filled with contents from one end 11a. Thereafter, the innermost sealant layer in the aluminum laminated resin sheet is heat sealed using a known heat sealing means while crushing the one end portion 11a into a flat shape.

The pump device 13 fixed to the mouth portion 11b of the container main body 11 is generally made of a synthetic resin such as a polyolefin resin, and includes a pump main body 15 and a nozzle portion 14 as shown in FIGS.
The pump body 15 includes a known pump mechanism including a measuring chamber 19 therein. The pump body 15 has an outer peripheral surface portion 16 that is in close contact with the inner peripheral surface 11c of the mouth portion 11b of the container main body 11, and the outer peripheral surface portion 16 is in close contact with the inner peripheral surface 11c and covered with the container main body 11. In this state, it is fixed to the mouth portion 11b.

  An outer shell portion of the pump body 15 is constituted by an outer peripheral surface portion 16 having a cylindrical sleep shape. The outer peripheral surface portion 16 has an outer diameter that is the same as or slightly larger than the inner diameter of the container main body 11, and therefore, the outer peripheral surface of the outer peripheral surface portion 16 is inserted into the mouth 11 b of the container main body 11 by the pump main body 15. When attached, it firmly adheres to the inner peripheral surface 11c of the mouth portion 11b.

  The outer peripheral surface of the outer peripheral surface portion 16 of the pump body 15 is made of a polyolefin resin or the like having heat sealing properties. And after attaching the pump main body 15 to the opening | mouth part 11b of the container main body 11, it heat-seals from the outer side of the container main body 11 using a well-known heat seal means, The outer peripheral surface of the outer peripheral surface part 16 of the pump main body 15 And the inner peripheral surface 11c of the mouth portion 11b of the container body 11 can be tightly bonded in an airtight state.

  The pump body 15 includes a cylinder 20, a piston 21, a suction valve 22, a discharge valve 23, a stem 26, a stem press 27, a spring 28, a spring press 29, and the like. The cylinder 20 has a cylindrical shape, and a suction valve 22 is provided at the lower end thereof. The piston 21 closely slides on the inner surface of the cylinder 20, and a discharge valve 23 is provided at the lower end thereof. A measuring chamber 19 is formed from a space closed by the inner surface of the cylinder 20 and the suction valve 22 and the discharge valve 23 of the piston 21.

  The stem 26 is a cylindrical member connected to the upper portion of the piston 21. The stem presser 27 presses the collar portion of the stem 26 from above, and inhibits the stem 26 from moving upward. The spring retainer 29 is a cylindrical member connected to the upper portion of the stem 26.

  A spring 28 is interposed between the stem presser 27 and the spring presser 29. Therefore, the spring retainer 29 is always urged in the direction away from the stem retainer 27 by the elastic force of the spring 28. However, since the nozzle portion 14 connected to the upper portion of the spring retainer 29 is restrained from moving upward by the pressing portion 64 of the lever 6 serving as pumping means, as will be described later, the spring retainer 29 is connected to the stem 26. There is no separation from.

  The nozzle portion 14 is provided so as to protrude upward from the pump main body 15 and is connected to the piston 21 via a spring retainer 29 and a stem 26 connected to the lower portion thereof. The flow path of the nozzle portion 14 has a crank shape (a shape bent at a substantially right angle and then bent at a substantially right angle in the opposite direction).

  According to the pump device 13 configured as described above, by repeating the pressing operation of the nozzle portion 14 (in the present embodiment, as will be described later, the pumping operation by the lever 6 as the pumping means causes the nozzle portion 14 to The piston 21 is slid in close contact with the cylinder 20 and the contents can be sucked from the container body 11 into the measuring chamber 19 via the suction valve 22 by the pumping action. Then, a necessary amount of the content sucked into the measuring chamber 19 can be discharged from the discharge port 14a of the nozzle portion 14 through the discharge valve 23, the stem 26, the spring retainer 29, and the like.

  In the container 10 with a pump of this embodiment, the pump apparatus 13 which has the structure mentioned above is provided in the two container main bodies 11 arranged in parallel, respectively, and the two container main bodies 11 and 11 arranged in parallel are arranged. The crank-shaped nozzle portions 14 and 14 of the pump devices 13 and 13 fixed to the mouth portions 11b and 11b are integrated in the vicinity of the discharge ports 14a and 14a, and the discharge ports 14a and 14a are adjacent to each other. . Therefore, the 1st agent and 2nd agent with which each of the accommodating part 11d (refer FIG. 2) of the two container main bodies 11 and 11 arranged in parallel is discharged from the adjacent discharge ports 14a and 14a. Therefore, the first agent and the second agent are ejected at substantially the same position. The flow paths 14b of the two nozzle portions 14 have substantially the same cross-sectional area and length.

  As described above, the pump device 13 is made of a synthetic resin such as a polyolefin resin. However, the pump device 13 formed of such a material does not itself have an oxygen barrier property. Thus, in the pump device 13 of the present embodiment, the measuring chamber 19 is filled with an inert gas with respect to the contents of the container body 11. Here, “inert” is relative to the contents. Specifically, examples of the gas inert to the contents that deteriorate with respect to oxygen, such as the hair dye in the present embodiment, include nitrogen gas and helium gas.

Next, the holder 5 will be described. The holder 5 is a member that holds the two container bodies 11 and 11 to which the pump devices 13 and 13 are fixed in a state where they are arranged side by side. The holder 5 is provided with two holding portions 51, 51 that can hold the container main body 11, and the holding portion 51 in the present embodiment directly connects the mouth portion 11 b of the container main body 11 or another member. It can be held indirectly via
The holder 5 is configured such that the container body 11 with the pump devices 13 and 13 fixed to the holding portion 51 is detachable. There is no restriction | limiting in particular about the structure which can attach or detach the container main body 11, For example, the fitting by inserting a convex part in a recessed part and the screwing by screwing a male screw and a female screw are mentioned. In this embodiment, fitting is used.

  The outer surface of the holder 5 forms a covering portion 52 that covers the mouth portion 11 b of the container body 11 held by the holding portion 51. The covering portion 52 is preferably configured such that the pump main body 15 is positioned inside thereof. In the present embodiment, one container main body 11 (container main body 11 shown on the right side in FIG. 2) has the pump main body 15 of the pump device 13 attached to the mouth portion 11 b positioned inside the covering portion 52. In the other container main body 11 (container main body 11 shown on the left side in FIG. 2), the pump main body 15 is located not only inside but also outside the covering portion 52.

  Next, the pumping means will be described. The pumping means performs the pumping operation of the pump device 13. In the present invention, the “pumping operation” refers to an operation that causes the pump device 13 to generate a pump action, and is performed by a user's manual operation. In the present embodiment, the lever 6 is provided as a pumping means, and the pumping operation of the pump devices 13 and 13 mounted on the two container bodies 11 and 11 arranged side by side is performed by pressing the lever 6. It is configured so that it can be performed in one operation. In addition, the lever 6 is pivotally supported on a rotation shaft 61 provided in the holder 5, for example, and is attached to the holder 5 so as to be rotatable.

  In the present embodiment, the lever 6 as the pumping means has a shape bent substantially at a right angle, and its base end portion 6A is located at the upper end portion of the holder 5 with the rotation shaft 61 as a rotation fulcrum. It is pivotally supported. A through hole 62 is provided in an upper portion of the intermediate portion 6B extending in the lateral direction from the base end portion 6A of the lever 6. By providing the through-hole 62 in the intermediate portion 6B, the portion in the vicinity of the discharge port 14a in which the two nozzle portions 14 are integrated penetrates the intermediate portion 6B of the lever 6, and the upper portion of the intermediate portion 6B. Protrude from.

  The intermediate portion 6B of the lever 6 is provided with a pressing portion 64 that protrudes toward the nozzle portion 14 so as to surround the through hole 62. The pressing portion 64 is in contact with the intermediate portion 14 c that extends in the lateral direction in the nozzle portion 14.

  The operation portion 6C of the lever 6 has a shape that is easy to grip, bends substantially downward at a right angle from the intermediate portion 6B, and extends to the side of the container body 11. Accordingly, the container body 11 whose periphery is covered by the holder 5 and a cover body 30 described later is gripped from the opposite side of the operation unit 6C so as to be wrapped in the palm, and the finger is placed on the operation unit 6C of the lever 6 to rotate it. If the lever 6 is operated so that the operation portion 6C is brought close to the container body 11 with the moving shaft 61 as a pivot point, both the nozzle portions 14 in the two pump devices 13 arranged in parallel are connected via the pressing portion 64. , And pressed downward (that is, toward the measuring chamber 19). As a result, the piston 21 moves up and down in the cylinder 20 to operate the pump device 13, so that the contents can be easily discharged from the discharge port 14 a of the nozzle portion 14.

  And in the container 10 with a pump of this embodiment, as shown in FIG.1, FIG.3 and FIG.4, the bottomed cylindrical cover body 30 which covers the accommodating part 11d of the container main body 11 is the lower end opening of the holder 5. The peripheral edge portion of the upper end opening 30a is locked to the peripheral edge portion of 5a, and the holder 5 is detachably attached to the holder.

  The cover body 30 is preferably formed by blow molding, for example, using a synthetic resin material such as PE, PP, and PET. The cover body 30 is formed in a bottomed cylindrical shape in which the bottom portion 31 and the cylindrical portion 32 are integrated, and the upper end surface opens as an upper end opening 30a. Moreover, the cover body 30 is shape | molded so that the thickness of the synthetic resin material in the cylinder part 32 may be 500-1500 micrometers, for example, and is equipped with moderate flexibility and shape retention rigidity. Thus, for example, the shape of the upper end opening 30a can be easily deformed by pressing the peripheral portion of the upper end opening 30a with a hand or a finger from the side while the upper end opening 30a is free (see FIG. 4). For example, in a state where the peripheral edge portion of the upper end opening 30a is constrained from the outside over the entire circumference and the upper end opening 30a cannot be expanded outward in the radial direction, the upper end opening 30a is compressed and deformed with a hand or a finger. Although effectively resisting the load and slightly deflected, the opening shape can be firmly held without causing large deformation (see FIG. 1).

  Here, in this embodiment, an uneven groove 33 or the like is appropriately provided outside the peripheral portion of the upper end opening 30 a of the cover body 30, and the uneven groove 33 is provided inside the peripheral portion of the lower end opening 5 a of the holder 5. The cover body 30 is mounted in a stable state on the holder 5 while being detachably locked to the provided locking uneven portion (not shown) and covering the accommodating portion 11d of the container body 11. It becomes possible. Further, a positioning uneven portion 34 is appropriately provided outside the peripheral portion of the upper end opening 30 a of the cover body 30, and the positioning uneven portion 34 is provided inside the peripheral portion of the lower end opening 5 a of the holder 5 ( (Not shown) can be detachably locked to prevent rotational movement of the cover body 30 with respect to the holder 5 during use. Further, for example, by providing a slit in the side portion of the cylindrical portion 32 of the cover body 30 and positioning the holder 5, the cover body 30 is prevented from being displaced from the set position by the rotation of the cover body 30, or the cylinder of the cover body 30. By marking the portion 32 to clearly crush the upper end opening 30a, the cover body 30 can be guided so as to be smoothly deformed in a desired shape and direction.

  Moreover, in this embodiment, the cover body 30 is shape | molded so that the bottom part 31 may have an elliptical planar shape and the upper end opening 30a may have a circular opening shape. The upper end opening 30 is crushed so as to be sandwiched from the outside so as to be deformed into an elliptical opening shape, and the peripheral portion of the upper end opening 30a is changed to the peripheral portion of the lower end opening 5a having the elliptical opening shape of the holder 5 The container body 11, the pump device 13, the holder 5, and the cover body 30 are integrated to form the double discharge type pump-equipped container 10 of the present embodiment. become.

  Here, in the present embodiment, the holder 5 is attached to and held by the pair of holding portions 51 and 51 in a state where the two container bodies 11 and 11 to which the pump devices 13 and 13 are mounted and fixed are arranged side by side. ing. Therefore, the lower end opening 5a by the covering portion 52 has an oval opening shape suitable for accommodating a pair of circular cross sections when viewed from below.

  And according to the container 10 with a pump of this embodiment which has the above-mentioned structure, the deformation | transformation of the container main body 11 by the holding force at the time of holding the container 10 and performing pumping operation is avoided, and stable pumping operation is smoothed. And the appearance can be prevented from being damaged. That is, the accommodating portion 11d of the tube-shaped container body 11 made of a flexible material is easily deformed when directly receiving a large gripping force when performing the pumping operation by the lever 6. According to this, the bottomed cylindrical cover body 30 that covers the housing portion 11 d of the container main body 11 and is attached to the holder 5 is provided. By gripping the cover body 30, the large operating force of the lever 6 is reduced. It will be easy to grip because it will gain strength. In addition, the cover body 30 supports the reaction force of the operation force in a stable state, and even when the content stored in the container body 11 has a high viscosity, the content can be smoothly smoothed by the pumping operation without deformation. An object can be discharged and the appearance of the container 10 is not impaired.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the holder is a double-type holder, and it is not always necessary that a pair of container main bodies are mounted side by side on the double-type holder, and only one container main body is attached to a holder having pumping means. May be. Also, the pump device does not necessarily have to be attached with the outer peripheral surface of the pump main body closely attached to the inner peripheral surface of the mouth of the container main body, and the pumping means needs to be a lever that is rotatably attached to the holder. Is not necessarily. Furthermore, it is not always necessary for the cover body to completely cover the container body, and a window or the like may be formed in the opening. Furthermore, the bottom portion of the cover body does not necessarily need to be completely closed, and may have an opening portion as long as the shape can be firmly held.
