Description

Technical Field

[0001] The present invention relates to a thin-walled container holder for accommodating a pouch container provided with a discharger or the like.

Background Art

[0002] For example, a holder for a thin-walled container is known that includes a support for supporting a pouch container as the thin-walled container, a cap for preventing the outflow of the contents accommodated in the pouch container, a discharger (a trigger spray for ejecting the contents), and a joint member for connecting the discharger and the support so that the pouch container can be accommodated in a replaceable state (for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the holder described in Patent Document 1, when the contents filled in the pouch container are reduced and the pouch container is replaced with a new one, after removing the cap on the pouch container side, it is necessary to connect the pouch container and the discharger via the joint member, so there is a problem that it is difficult to reduce the number of parts. Moreover, since both the connection between the joint member and the connection part (collar part) of the discharger and the connection between the joint member and the spout of the pouch container are screw-fitted, there is also a problem that the replacement work is complicated.

[0005] An object of the present invention is to create a thin-walled container holder that can reduce the number of parts by eliminating the joint member and can be replaced by a simple operation in order to solve the above problems in the prior art.

Means for Solving the Problems

[0006] Among the means for solving the above problems, the main means of the present invention is: A thin-walled container holder comprising: a thin-walled container filled with contents; a dispenser that sucks up and discharges the contents from the thin-walled container; a holder body that replaceably houses the thin-walled container equipped with the dispenser; and a lid that is openable and closable with respect to the holder body, The discharger has a cylinder into which a flange portion is formed, and the container has a spout into which the discharger is inserted. The top wall of the lid is characterized by having a bifurcated portion that presses down on the flange portion when the lid is closed. In the first means of the present invention, when the lid is closed, the bifurcated portion provided on the lid presses down on the flange portion of the dispenser, so that the thin-walled container can be easily and quickly replaced.

[0007] Furthermore, a second means of the present invention adds to the first means described above that the top surface of the holder body is provided with a first opening that extends from the opening and opens in a U-shape in plan view, and a fitting recess provided in the spout is slidably fitted onto the edge of the first opening. In the above method, by fitting the fitting recess provided in the spout onto the edge of the first opening, the thin-walled container can be slid between the open part and the center of the holder body, thereby facilitating the replacement of the thin-walled container.

[0008] Furthermore, a third means of the present invention adds to the second means described above, a second opening having a U-shape in plan view is formed between the bifurcated portion provided on the top wall of the lid, and when the lid closes the open portion of the holder body, the arc portion of the first opening and the arc portion of the second opening face each other radially to form an engagement hole, and a fitting recess provided on the spout fits into the inner edge of the engagement hole. In the above method, the thin-walled container can be securely held in the center of the top surface of the holder body by fitting the fitting recess of the spout into the engagement hole.

[0009] A fourth means of the present invention is to add to any of the above means that the bifurcated portion has a curved shape that curves downward as it approaches the tip. With the above method, the bifurcated portion can firmly hold down the flange portion, thus reliably suppressing rattling of the discharger. [Effects of the Invention]

[0010] In this invention, since a joint member is not required to connect the thin-walled container and the dispenser as in the conventional invention, the number of parts can be reduced. Furthermore, since the connection between the spout of the thin-walled container and the dispenser is not made by screw fitting, the replacement of the thin-walled container can be done easily and quickly.

Embodiments for Carrying out the Invention

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a thin-walled container holder showing a state in which a pouch container to which a dispenser is attached is accommodated as an example of an embodiment of the present invention, FIG. 2 is a cross-sectional view of the pouch container, FIG. 3 is a cross-sectional view of the dispenser, FIG. 4 shows the holder body, (a) is a plan view, (b) is a cross-sectional view on the front side, (c) is a cross-sectional view on the side, FIG. 5 shows the lid body, (a) is a plan view, (b) is a side view, and FIG. 6 is a side view of the thin-walled container holder showing a state in which the pouch container is attached to the holder body. In the following, the direction along the container axis O will be referred to as the axial direction, the vertical direction or the height direction, the direction orthogonal to the container axis O will be referred to as the radial direction, and the direction of orbiting around the container axis O will be referred to as the circumferential direction for explanation.

[0013] As shown in FIGS. 1 to 5, the thin-walled container holder 1 of the present invention includes, for example, a pouch container (thin-walled container) 10 (see FIG. 2) filled with a liquid content such as shampoo or body soap, a manual dispenser 20 (see FIG. 3) that sucks up and discharges the content from the pouch container 10, a holder body 30 (see FIG. 4) that accommodates the pouch container 10 provided with the dispenser 20 in an exchangeable manner, and a lid body 40 (see FIG. 5) that opens and closes the front surface of the holder body.

[0014] The pouch container (thin-walled container) 10 shown in FIG. 2 is formed in a bag shape by heat-sealing the bottom portion 12 of a container body 11 made of a synthetic resin film having a flexible multilayer structure. A spout 14 made of synthetic resin is heat-welded and attached around the opening 13 at the upper part of the container body 11. The spout 14 is configured to have a double short cylindrical base portion 14a inserted and disposed inside the opening 13, and an upper end opening edge 14b continuously provided at the upper part of the base portion 14a and extending annularly outside the opening 13. A fitting recess 14c formed in a U-shaped cross-section is provided around the portion where the upper surface of the base portion 14a and the lower surface of the upper end opening edge 14b face each other. The outer diameter dimension of the fitting recess 14c is W1.

[0015] In the pouch container 10, when the container body 11 is filled with the content, the opening 13 is sealed by attaching a thin aluminum seal 15 to the upper surface of the upper end opening edge 14b. In addition, the inner diameter dimension of the spout 14 is formed to be larger than the maximum outer diameter of the cylinder 23 of the discharger 20 described later.

[0016] The discharger 20 has a conventionally known configuration. In the illustrated example, it includes a stem 21 that is erected so as to be movable downward in an upwardly biased state, a piston 22 linked to the stem 21, a cylinder 23 in which the piston 22 is fitted so as to be slidable up and down, a regulating cylinder 24 that is attached to the upper part of the stem 21 and regulates the upward movement of a pressing head 25 described later, and the like.

[0017] Furthermore, the discharger 20 has a discharge nozzle 25a for discharging the content, a pressing head 25 attached to the upper end of the stem 21, a piston guide 26 that is attached to the lower part of the stem 21 and is disposed so as to be movable up and down in the cylinder 23, a valve member 27 that is disposed in a portion of the cylinder 23 located below the piston guide 2- 6 and opens and closes the lower end opening of the cylinder 23, a coil spring C that biases the piston guide 26 upward, and the like.

[0018] The cylinder 23 is formed in a multi-stage cylindrical shape in which the outer diameter increases as it is located higher, and an annular flange portion 23a that protrudes outward in the radial direction is formed over the entire circumference at its upper part. Also, a protruding cylinder 23b that is continuous from the upper part of the cylinder 23 extends upward on the flange portion 23a. In the state where the discharger 20 is attached to the pouch container 10, the flange portion 23a is disposed on the upper end opening edge 14b of the spout 14 (see FIG. 10).

[0019] The cylinder 23 has an inlet hole 23c that penetrates radially. The inlet hole 23c is closed when the piston 22 reaches the upper end position of the stem 21. A long, cylindrical suction tube S, which is separate from the discharger 20, is fitted to the lower end opening of the cylinder 23. The suction tube S has a length that, when the discharger 20 is attached to the pouch container 10, brings its lower end opening close to the bottom 12 of the container body 11. By preparing the suction tube S separately from the discharger 20, the optimal suction tube S can be attached to the discharger 20 according to the specifications (size and type) of the container body 11.

[0020] The regulating cylinder 24 is composed of a male threaded cylinder 24A inserted into the cylinder 23, a connecting ring 24B projecting radially outward from the middle portion of the male threaded cylinder 24A, an outer fitting cylinder 24C hanging down from the lower surface of the connecting ring 24B and fitted onto the outside of the protruding cylinder 23b, and an outer casing cylinder 24D extending downward from the outer peripheral edge of the connecting ring 24B.

[0021] The valve member 27 is a check valve that keeps the lower end opening of the cylinder 23 closed when the cylinder 23 is pressurized, and opens the lower end opening of the cylinder 23 when the pressure inside the cylinder 23 is reduced. As a result, when the cylinder 23 is pressurized, the contents inside the cylinder 23 are prevented from returning to the pouch container 10 through the lower end opening of the cylinder 23, and when the pressure inside the cylinder 23 is reduced, the contents inside the pouch container 10 flow into the cylinder 23 through the lower end opening of the cylinder 23.

[0022] When the push head 25 is pressed and moved downward together with the stem 21 and piston guide 26, the piston 22 and valve member 27 are activated, causing the contents of the cylinder 23 to flow into the stem 21, and thus allowing them to be discharged from the tip of the discharge nozzle 25a. When the pressure on the push head 25 is released, the upward biasing force of the coil spring C causes the stem 21, piston 22, piston guide 26, and push head 25 to return to their original position upward, and the contents of the pouch container 10 flow into the cylinder 23. During this process, the pressure inside the cylinder 23 decreases, causing the valve member 27 to open the lower end opening of the cylinder 23, and the contents of the pouch container 10 flow into the cylinder 23 through the suction cylinder S.

[0023] As shown in Figure 4, the holder body 30 is composed of a top surface portion 31 which is U-shaped in plan view, a peripheral wall portion 32 which is U-shaped in plan view and extends downward from the outer peripheral edge on the lower side of the top surface portion 31, and a bottom wall portion 33 which is horizontally connected to the lower end of the peripheral wall portion 32. The front side of the peripheral wall portion 32 is an open portion 34 without a wall. The top surface portion 31 has a first opening 31a which opens in a U-shape in plan view, continuing from the open portion 34, and a pair of regulating ribs 31b are provided protruding from the upper surface of the top surface portion 31. Furthermore, locking vertical grooves 32a are formed on both upper inner surfaces on the open portion 34 side (front side) of the peripheral wall portion 32, and through holes 32b are drilled on both lower inner surfaces. Furthermore, the width dimension W2 of the first opening 31a is set to be the same as the outer diameter dimension W1 of the fitting recess 14c.

[0024] As shown in Figure 5, the lid 40 is composed of a front plate 41 that covers the opening 34 of the holder body 30, a top wall 42 that extends horizontally from the upper part of the front plate 41, and a pair of side walls 43 that extend from both sides of the front plate 41. The upper part of each of the pair of side walls 43 is provided with a locking projection 44 that protrudes outward, and the lower part of each is provided with a rotating shaft 45 that protrudes outward. The top wall 42 extends upward via a U-shaped stepped portion 42a in plan view, and its tip is formed into a bifurcated portion 42A that branches into two. A second U-shaped opening 42B in plan view is formed between the bifurcated portions 42A. The bifurcated portions 42A are formed with a curved shape that curves downward towards the tip.

[0025] The lid 40 is rotatably mounted on the front surface of the holder body 30 by inserting the rotating shaft 45 into the through hole 32b of the holder body 30. By rotating the lid 40 around the rotating shaft 45, the opening portion 34 can be opened and closed.

[0026] Next, the effects and advantages of the present invention will be described. Figure 6 is a side view of the thin-walled container holder showing the pouch container attached to the holder body, Figure 7 is a side view of the thin-walled container holder showing the dispenser attached to Figure 6, Figure 8 is a side view of the thin-walled container holder showing the lid closed from Figure 7, Figure 9 is a top view of the thin-walled container holder when the lid is closed, and Figure 10 is an enlarged cross-sectional view of section X in Figure 1 when the lid is closed. Note that Figure 9 omits the dispenser 20 to show the relationship between the top surface 31 of the holder body 30 and the top wall 42 of the lid 40. Also, in Figure 10, the bifurcated portion 42A is shown in light gray.

[0027] As shown in Figure 6, with the lid 40 tilted forward in the open position, the pouch container 10 is attached to the top surface 31 of the holder body 30. At this time, the width dimension W2 of the first opening 31a provided in the top surface 31 is set to be the same as the outer diameter dimension W1 of the fitting recess 14c side of the spout 14. Therefore, the fitting recess 14c of the spout 14 can be fitted onto the edge of the first opening 31a from the open portion 34 side, and in this state, the pouch container 10 can be slid to the center of the holder body 30.

[0028] Next, as shown in Figure 7, the dispenser 20 is attached to the pouch container 10. Specifically, the dispenser 20 is inserted into the spout 14 on the pouch container 10 side, which protrudes upward from the top surface 31 of the holder body 30. At this time, the aluminum seal 15 is peeled off first to open the spout 14. Alternatively, the aluminum seal 15 sealing the spout 14 may be forcibly broken through with the lower end S1 of the suction cylinder S of the dispenser 20 to open it. After opening, the dispenser 20 is further moved downward until the flange portion 23a contacts the top surface 31 of the holder body 30, and the cylinder 23 is inserted into the container body 11.

[0029] Next, as shown in Figure 8, the lid 40 is lifted and rotated around the rotation axis 45 to close the opening 34. At this time, the locking projections 44 protruding from the pair of side walls 43 on the lid 40 side engage with the vertical grooves 32a formed on both upper inner surfaces of the peripheral wall portion 32 on the holder body 30 side, thereby setting the thin-walled container holder 1 to a closed state (see Figure 1).

[0030] At this time, as shown in Figure 9, on the top surface 31, the bifurcated portion 42A on the lid 40 side moves between a pair of opposing regulating ribs 31b, and the arc portion of the first opening 31a and the arc portion of the second opening 42B face each other radially, forming an engagement hole 50. The pouch container 10 is held on the top surface 31 of the holder body 30 by the fitting recess 14c of the spout 14 fitting into the inner edge of the engagement hole 50. Then, as shown in Figure 10, the upper part of the cylinder 23 directly below the flange portion 23a of the dispenser 20 is positioned inside the engagement hole 50.

[0031] Furthermore, when the lid is closed, the curved bifurcated portion 42A fits between the lower end of the outer casing 24D of the regulating cylinder 24 and the upper opening edge 14b of the spout 14, holding down the flange portion 23a of the discharger 20. The bifurcated portion 42A, which is formed in a curved shape that curves downward towards the tip, firmly holds down the flange portion 23a, thereby reliably suppressing rattling of the discharger 20.

[0032] When the contents of the pouch container 10 are gone and replacement is required, the front plate 41 of the lid 40 is rotated outward to release the engagement between the locking projection 44 and the vertical groove 32a, and at the same time, the bifurcated portion 42A and the flange portion 23a are detached from the upper end opening edge 14b of the spout 14. Then, the pouch container 10 can be easily removed by sliding it along the first opening 31a from the center of the holder body 30 to the opening portion 34.

[0033] As described above, the present invention does not require a joint member to connect the pouch container 10 and the dispenser 20, thus reducing the number of parts. Furthermore, since there is no need to screw-fit the spout 14 of the pouch container 10 and the dispenser 20, the pouch container 10 can be replaced easily and quickly.

[0034] The configuration of the present invention and its effects have been described above in accordance with the examples, but the embodiments of the present invention are not limited to the above examples. For example, in the above embodiment, a pouch container was shown and described as an example of the thin-walled container 1, but any thin-walled container made of synthetic resin, such as a bottle-type container (so-called PET bottle), may also be used.

[0035] Furthermore, although the dispenser 20 was described as a push-button type, it may also be a trigger-spray type dispenser in which the contents are dispensed by squeezing the handle. [Industrial applicability]

[0036] The present invention can be applied to an even wider range of fields in the field of thin-walled container holders that accommodate thin-walled containers such as pouch containers. [Explanation of Symbols]
