Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a complex in which a repeatable support cylinder supporting a thin-walled container body made of a minimum amount of material for protecting a liquid content and a repeatable support tube are coupled by a tightening tool in a relationship that makes them difficult to rotate. In addition, the present invention relates to a resource-saving complex that can be easily assembled or removed.

[0002]

[Prior Art]

 The liquid contents currently in use, especially household containers for shampoo or rinse, are put to practical use with a pump for extrusion attached. The points required from this usage pattern are the strength to withstand the mechanical force of pressing the pump and maintain its shape and the strength to withstand the internal pressure of the container applied by the pump and to push the liquid content out of the container. In order to achieve this strength, wall thickness has been given to the vessel wall far above the level required to protect liquid contents.

Household containers containing these liquid contents are discarded and hardly reused when the contents are consumed. As a result, the situation in which more material resin was consumed than was necessary was inevitably accepted. This situation is against the environmental conservation, resource saving, and energy saving, which is becoming a global trend because it creates more waste containers than necessary.

[0004]

[Problems to be solved by the device]

 The present inventors have repeated various studies in search of a measure for promoting the effective use of resources and saving energy by reducing the amount of waste, which are the problems associated with the above-mentioned conventional techniques. There are already many proposals as measures against this. However, they are one step away from lacking a decisive factor. In other words, the cost has increased significantly, the amount of non-burnable waste has increased, the amount of carbon dioxide generated has increased, or the amount of energy required for waste treatment has increased. The inventors of the present invention have made new studies as a result of solving these difficult problems, and have completed the present invention.

[0005]

[Means for Solving the Problems]

 The present inventors have developed the following means in order to solve the problems: -Reduce the conventional container wall thickness to the minimum necessary level to protect the liquid contents-Pressure pressure and Fit a support cylinder (support frame) that has sufficient strength and can be used repeatedly to the outside of the container to make up for the lack of pressing strength.-Fix the container and support cylinder with a tightening tool to form a composite. ..

Hereinafter, the present invention will be described in detail with reference to the drawings. [First Embodiment] FIG. 1 is a longitudinal sectional view of a composite body of the present invention in which a container body 1 and a support cylinder 2 are fixed by a tightening tool 3 in a state in which they are difficult to rotate. In FIG. 1, the container bottom of the container body 1 has already been pushed down to form a round bottom, and the support cylinder 2 is fitted to the outside thereof from the mouth side of the container body 1. Before use, the pump P is inserted into the container and fixed with the screw lid 1c.

On the outer wall of the neck 1n of the container body 1 shown in FIG. 1, a rotation preventing convex portion 21 projects outward under the collar portion 12. The details are shown in FIG. Since the container main body 1 containing the liquid contents is provided as a single unit in the distribution path, it is necessary to fit the support cylinder 2 on the outside of the container main body 1 and then mount the pump P on the head of the container to put it into a use state. Usually done by the purchaser. Further, since it is usually necessary for the purchaser to remove the pump P and replace it with a new container when the used state is reached, it is required that the work is easy in any case.

The container body 1 of the present invention is usually made of a thermoplastic resin such as polyethylene, polypropylene or poly-4-methyl-1-pentene, and is the minimum necessary machine to protect the contents. Since it is only given the desired strength, it is necessary to fit the support cylinder 2 on the outside in order to use it in the usual manner. The support cylinder 2 is usually a tubular body without a bottom and with a shoulder.

The top opening edge of the support cylinder 2 rises slightly upward to form a frame 21, and a rotation prevention convex portion 22 rises outward from the vicinity of the foot of 21. However, even though the support cylinder is a “cylindrical body”, it is not necessary that the side wall and the like are completely continuous and non-perforated. There is no particular limitation on the shape of the support cylinder 2 and the side wall structure thereof as long as it has a reinforcing ability to absorb the internal pressure applied to the container body 1 accommodated through the pump P.

Since this support cylinder 2 is required to withstand the pressure applied from above and the swelling pressure from the inside of the container in repeated use, it has sufficient strength, which is contrary to the container body 1, and usually a sufficient source thereof. Being thick is important. As the material of the support cylinder 2, metal, hard plastic or other material having excellent shape retention can be appropriately used. Among them, hard plastics can be practically superior because they are easy to mold, in particular, they are light in weight, they are light in weight, they do not easily corrode, and they are economical.

In FIG. 1, after the support cylinder 2 is fitted on the container body 1, the support cylinder 2 is fitted between the top opening of the support cylinder 2 below the collar-shaped portion 12 provided on the neck 1n of the container body 1. Wear the tightening tool 3 of the present invention shown in.

The tightening tool 3 in FIG. 2 is substantially similar to the capital letter of the Roman character “C” in a plan view, has the protrusions 3c at both ends of the planar base 31, and corresponds to the back of the “C”. A bracket 3b with a hole is provided at the position. The both end projecting portions 3c normally serve as a guide member when the tightening tool 3 is attached to the container body 1 or the neck of the support tube 2.

FIG. 2A is a plan view of the upper portion of the tightening tool 3, in which the inner peripheral edge 3i of the tightening tool 3 is provided with three rotation preventing (rotating stop) convex portions 32 inwardly. There is. Its role is to prevent relative rotation between the container body 1 and the support tube 2 which are tightened. That is, when the support cylinder 2 is attached to the outside of the container body 1, the rotation of 1 cannot be suppressed when the lid is screwed into or removed from the screw provided on the neck 1n of the container body 1. , It causes difficulty in attaching and detaching the lid. In order to eliminate this difficulty, it is necessary to prevent the container body 1 from rotating (preventing rotation) regardless of the support cylinder.

However, “rotation prevention” as used herein is a degree of “unlimited rotation prevention” that allows some rotation. In other words, it is sufficient if the "rotation" between the container body and the support cylinder is limited to the extent that the screw lid can be attached and detached by rotation.

The number, shape, arrangement, etc. of the convex portions 32 for preventing rotation can be appropriately selected as necessary. The number of convex portions is usually 3 to 8 and it is sufficient to prevent the normal rotation when the inner peripheral edge 3i is equally spaced. The base 31 of the tightening tool 3 is provided with one or more notches (slits) 33 that converge from the inner peripheral edge 3i toward the outer peripheral edge 3e. The role of 33 is to provide wrapping easiness (curvature increase) for facilitating tightening.

As one mode (not shown) of the tightening tool having both the notch and the reinforcing ridge, the reinforcing ridge 35 is provided in the intermediate region between the outer peripheral edge 3e and the inner peripheral edge 3i of the base 31, and the notch is provided at the outer periphery. If it is provided so that it converges toward the reinforcing ridge from the edge and also converges toward the reinforcing ridge from the inner peripheral edge, it is possible to obtain a tightening tool capable of coping with various situations.

FIG. 2B is a sectional view of the tightening tool 3 taken along the line AA. According to FIG. 2, it can be seen that the protrusions 34 project inward from the protrusion 35 and the inner wall thereof that are continuous with the back side of the outer peripheral edge of the base 31. This state is further shown in FIG. 2 (c).

FIG. 2 (c) shows the back side of the tightening tool 3, and may also be referred to as a “bottom view”. In FIG. 2 (c), three rotation preventing convex portions 34 rising from the inner wall of the protrusion 35 provided on the lower surface of the tightening tool 3 are recognized. The number, shape, arrangement, etc. of the convex portions 34 can be appropriately selected as necessary.

The partially enlarged cross-sectional view shown in FIG. 3 (a) makes it easy to understand the mutual positional relationship between the convex portion 32 1, the convex portion 34, the convex portion 11 and the convex portion 22 for preventing rotation in FIG. It is for doing. In FIG. 3 (a), the tightening is such that the convex portion 11 that projects outward from below the collar-shaped portion 12 located in the lower part of the neck 1n of the container body 1 to the lower end of the neck 1n is located on the front side thereof. The protrusions 34 on the inner peripheral edge of the tool 3 are in contact with each other to prevent the partner from rotating.

On the other hand, the convex portion 22 protruding outward from the outer wall of the frame 21 at the top opening of the support cylinder 2 is an inner wall of the protrusion 35 protruding downward from the outer peripheral edge of the tightening tool 3 and the bracket 3 having a hole. The protrusions 34 protruding inward from a position close to b are contacted with each other to prevent mutual rotation of the other. This relationship becomes more apparent according to Fig. 3 (b) and Fig. 3 (c).

FIG. 3B shows a state in which the tightening tool 3 is attached and is cut along a line AA. In FIG. 3, the tightening tool 3 is cut in a horizontal plane, and the container body 1 is cut in the neck thereof perpendicularly to the axis. As a result, FIG. 3B clearly shows a state in which the convex portion 11 on the outer wall of the neck of the container body is in contact with the convex portion 32 on the inner peripheral edge of the tightening tool 3. On the other hand, FIG. 3 (c) shows a cross section taken along the line BB in the state of FIG.

FIG. 3C shows the fitted state of FIG. 3 by the relationship between the support cylinder 2 and the tightening tool 3. FIG. 3 (c) shows a convex portion 34 that rises inward from the reinforcing portion 35 that is provided on the outer peripheral edge 3 e of the lower surface of the tightening tool 3 and the convex portion 22 that is provided at the foot of the top opening of the support tube 2. Indicates that and are in contact with each other. All of these convex portions 32, convex portions 11, convex portions 34, and convex portions 22 are one or more, usually three or more, and they are arranged at predetermined positions at substantially equal intervals and are in contact with each other. [Second Aspect] FIG. 4 is a second aspect of the present invention, in which a tightening tool 4 having no convex portion on its surface has a container body 1 having a convex portion 11 and a support cylinder 4 having a convex portion 22. Shows the combined state of and. To show this relationship in more detail, FIG. 5 shows the shape of the tightening tool, and FIG. 6 shows the engagement relationship of the convex portions in an enlarged manner.

FIG. 5A is a top plan view (top view) of the tightening tool 4 of the second embodiment. In FIG. 5 (a), the plan shape of the tightening tool 4 is substantially similar to the Roman letter "C" capital letter. The "C" -shaped base portion 41 has a substantially flat shape and has bulges 4c at both ends thereof, and a bracket 4b with a hole bulges at a position corresponding to its back. Further, the base portion 41 is provided with one or more notches 43 that converge toward the outer peripheral edge 4e from the inner peripheral edge 4i, two in FIG. The role of the notch 43 is to provide the easiness of winding (increase the curvature) for facilitating the tightening of the tightening tool 4, similarly to the above-mentioned notch.

The notch 43 may be one converging from the outer peripheral edge 4e of the tightening tool 4 toward the inner peripheral edge 4i, contrary to the illustration. In that case, it is desirable to provide a reinforcing portion on the inner peripheral edge 4i. It can be clearly seen from FIGS. 5 (a) and 5 (b) that the tightening tool 4 is not provided with any protrusions for preventing rotation.

FIG. 5B is a cross-sectional view of the tightening tool 4 according to the second embodiment shown in FIG. 5A, taken along the line AA. FIG. 5C shows the state of FIG. 5A viewed from the back side (lower side) thereof. The partial enlarged cross-sectional view of FIG. 6A clearly shows the mutual contact relationship between the rotation preventing convex portion 11 and the rotation preventing convex portion 22. From FIG. 6 (a), the convex portion 11 protruding outward from the foot of the neck 1n of the container body 1 protrudes inward from the inner wall of the bent portion at the base of the top opening frame 21 of the support tube 2. It can be seen that they are in contact with each other and do not easily rotate. The mutual positional relationship between the convex portion 11 and the convex portion 22 is shown in FIG. 6 (b).

In FIG. 6B, a plurality of pairs of the plurality of protrusions 11 and 22 are in contact with each other, and the others are isolated. However, the isolated convex portion plays a role of limiting the range in which any convex portion rotates to the right or left. The strictest example of rotation regulation is shown in Fig. 6 (c).

In (c) of FIG. 6, since the two convex portions 22 of the support cylinder 2 are sandwiched between the two convex portions 11 of the container body 1, it is almost impossible to rotate. is there. On the contrary, the two convex portions 11 of the container body 1 are also sandwiched between the two convex portions 22 of the support cylinder 2, so that the rotation is prevented. This kind of strict "rotation prevention" is not required for normal screw lid attachment and detachment work. [Third Aspect] As the third aspect of the complex of the present invention, the aspects shown in (a) of FIG. 7 and (b) of FIG. 8 can be mentioned. 7A is a vertical sectional view of the composite, and FIG. 8B is a horizontal sectional view of the composite taken along the line AA. The third mode is one in which a rotation preventing means different from the above-described modes is introduced.

The third aspect of the composite body of FIG. 7A is common to the above-described aspects in that the container body 5 and the support cylinder 6 are fixed by the tightening tool 4 near the necks of both parties. However, there is no rotation-preventing protrusion on the container body 5 near the neck 5n, near the top opening of the support tube 6 or on the wall surface of the tightening tool 4.

As an alternative rotation preventive measure, in the third aspect of the composite of FIGS. 7A and 8B, the container body 5 (having a shape different from that of the container body 1 described above) is used. A concave portion (groove) 51 is provided on the outer wall generatrix of the supporting cylinder 6 (which has a different shape from the supporting cylinder 2 described above). A ridge 61 is provided on the inner wall generatrix (which is given a different reference numeral for the sake of illustration). The ridge 61 fits into the recess 51 and fulfills the intended rotation prevention function. The relationship of this rotation preventing engagement is clearly shown in FIG. 8 (b). [Fourth Aspect] As a fourth aspect of the complex of the present invention, there may be mentioned the ones shown in FIGS. 9 to 11. This aspect is common to the third aspect of the composite body of FIGS. 7 (a) and 8 (b) in that it does not have a convex portion for preventing rotation, but the above-mentioned winding fastener is a tightening tool. In addition to adopting a completely different kind of slide lock, we also changed the neck cross-sectional shape of the container body to enable the slide lock function.

The fourth aspect of the composite body of FIGS. 9 to 11 is that of the container body 7 (different reference numerals are given to indicate that the container body 1 or 5 has a different shape). The neck 7n has a non-circular cross section, and the tightening tool 9 is substantially plate-shaped so that the locking mechanism can be attached and detached by sliding.

What is shown in FIG. 8 as an example of the cross-sectional shape “non-circular” in the neck portion 7n of the container body 7 is commonly called “oval type”. However, “non-circular” is not limited to “oval”. Any shape that allows the lock mechanism to be attached and detached by sliding can be used for the purpose of the present invention. For example, a rectangle can be used.

On the other hand, what is illustrated in FIGS. 10 and 11 as the tightening tool 9 (different reference numerals are given to show that it has a different shape from the above-described tightening tool 3) Is a shape in which a pseudo keyhole type window is provided in the frame of a substantially rectangular plate. The diameter of the round hole 91 in the pseudo-keyhole type window hole is required to be large enough for the collar-shaped portion 72 provided on the neck portion 7n of the container body 7 to pass through.

Further, the shape of the non-circular hole 92 in the keyhole type opening is formed by two parallel straight lines and an arc connecting them so as to fit into the oval cross section of the neck 7n of the container body 7. There is. The length of both of these straight line portions is usually 2/3 or more, preferably 3/4 or more with respect to the length of the oval type straight line portion. If the straight part is too short, there is a risk of accidental unlocking.

The cross-sectional shape of the neck portion 7n of the container body 7 may be a shape formed by straight lines on all four sides such as a pseudo rectangle (rounded rectangle). The support cylinder 8 in the fourth embodiment of the composite body of FIG. 9 (which is given a different reference numeral to show that the support cylinder 2 or 6 has a different shape) Since there is no rotation prevention structure between them, the top opening frame 81 may be a frame with a rounded square shape, as shown in FIGS. 10 (a) and 11 (a), in order to supplement it. It is beneficial. Further, snap bosses 82 are provided on both sides on the movement line of the slide lock type tightening tool 9 on the outer side of the frame. The role of the snap boss 82 is to prevent the tightening tool 9 from sliding naturally from a predetermined position.

That is, in FIG. 10 (a), the snap boss 82 located at the left end of the tightening tool 9 suppresses its untimely movement in order to keep the tightening tool 9 in the locked position. .. On the other hand, in FIG. 11A, the snap boss 82 located at the right end of the tightening tool 9 restricts its natural movement in order to keep the tightening tool 9 in the open position. However, even if the snap boss 82 has too large a deterrent capability, it cannot meet the expectations of the present invention. The deterrent ability should be within a range that can be broken through by the action of pushing or pulling strongly with the force of human fingers.

Further, the tightening tool 9 of FIG. 9 further incorporates a detachment preventing mechanism also shown in FIGS. 10 and 11 in order to avoid a situation of rising from the mounted state. That is, the guide ridges 83 protruding horizontally from the top opening frame 81 of the support cylinder 8 can slide in the guide grooves 93 provided in the inner wall of the ridge 9c rising from the rear side of the periphery of the tightening tool 9 in parallel with the sliding direction. Has been inserted into. It suffices if this guide groove 93 (the lower edge of which is defined by the overhang 94) is provided over the left half of the back surface of the tightening tool 9.

The container body forming the composite of the present invention is usually a cylindrical round bottom at the time of molding. At the stage of filling the contents of this container, the bottom of the container is changed into a state of being depressed into the container. The purpose is to save the occupied space during transportation and storage, and to reduce the rupture even if a rapid pressure is applied while the contents are focused.

The shape of the bottom portion of the container body can be variously changed according to its use, and as a modification thereof, the one shown in FIG. 12 can be exemplified. However, even in the container body of FIG. 12, the bottom of the container is recessed into the container at the stage after filling the contents.

In FIG. 12 (a), the central portion 10b of the vessel bottom is disk-shaped, and the lower shoulder portion 10s connected to it is formed of a curved surface like a conventional container. The container body 10 is filled with a liquid content to finally form a state in which the vessel bottoms 10s and 10b are recessed into the vessel. Its purpose is as described above. Since the container body 10 filled with the liquid contents is difficult to stand on its own, when displaying without a support tube fitted on the display such as in a store display, the container body 10 is as illustrated in FIG. 12 (c). The purpose can be achieved by fitting a hard cylinder 10t (commonly called "hakama") to the outside of the main body 10 from below. When the hakama 10t is fitted, the bottom of the container body changes to a round bottom 10r as shown.

The “hakama” 10t is required to be self-supporting and have a hardness sufficient to support a flexible container body, but the material is not generally limited. If the window hole 10w is provided on the side wall of the hakama, the remaining amount of the liquid content can be visually confirmed.

[0041]

[Effect of the device]

 With the composite of the present invention, the following various effects can be achieved: -The amount of resin consumed in the replacement container can be reduced. That is, it contributes to resource saving.-Since the support cylinder and the tightening tool can be used repeatedly, it is possible to reduce the material consumption within the same period. This also contributes to resource saving.-The labor and energy for transporting the replacement container can be saved.-The operation of replacing the container at the site of use does not require tools or skills and is easy. Can be executed.
