Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container, and in particular, saves resources by reducing the amount of resin material per unit storage capacity required for manufacturing the container, and at the same time reduces the volume of a used container. The present invention relates to a resource-saving and environmentally-friendly container whose purpose is to prevent environmental damage due to waste, and a reinforcing case which facilitates its use.

[0002]

Flexible containers for storing fluids such as water are widely used as water pillows and other cushioning devices.
These containers are used with the inlet and outlet of the fluid being sealed. However, if the container intended to supply the contents from the discharge port is made to have a flexible and expandable / contractible structure, once the fluid supply port is opened, external force is applied to the container body. Because its contents are easily dispensed by, many general-purpose fluid containers, which may be carried by hand after opening or may be grasped by the hand while being opened, are substantially more rigid than before. It is constructed with a solid container body.

[0003]

At present, a container made of synthetic resin is used for many purposes, but since this kind of container is cheaper than a container made of metal, most of them are not used after use. It is a disposable container that is discarded. The heavy use of disposable containers poses a problem of limited resource depletion and environmental destruction due to waste.

The present invention addresses the problems of resource depletion and environmental damage described above, and replaces a conventional container having substantially the same handling property after opening with a conventional rigid structure with a conventional container. An object of the present invention is to provide a resource-saving and environmentally-friendly container that can be manufactured with a significantly smaller amount of material and the volume of waste after use can be significantly reduced compared to conventional containers. It is an issue.

[0005]

In order to solve the above-mentioned problems, the present invention provides a flexible and expandable / contractible container body, a rigid nozzle part connected to a part of the container body, and A cap locking device that seals the opening end of the nozzle portion; and a cap locking device that locks the cap that is supported by the nozzle portion and that is attached to the nozzle portion at a position that seals the opening end at the position. The container body and the base of the nozzle are rigidly loaded into a reinforcing case that can be opened and closed, and the container body is stored with the opening end of the nozzle protruding from the reinforcing case. The container is a container for delivering the fluidized material from the nozzle portion, and the container main body portion and the root portion of the nozzle portion are loaded into the reinforcing case in a state where the reinforcing case is opened. The root part of the When the reinforcing case is closed in the state set to the position, the container locking action of the cap locking device is released by the closing movement of the reinforcing case. .

No matter how flexible the container body is,
If a fluid, in particular an incompressible fluid, is sealed inside and a rigid part is present in a part of the container, it is a rigid container for carrying and other handling by hand. You can do it with almost the same.

[0007]

Although the above-mentioned container certainly needs the aid of a reinforcing case in its use, there are many examples in which the fluid is put in a container and used (for example, Even if the fluid used for use is consumed by an unlimited number of containers, such as the ink supply source in a stencil printing machine, only one container is temporarily used at any moment. In applications where it is not used, the above-mentioned container can be used innumerably by using only one reinforcing case, and the container is manufactured and discarded in proportion to the amount of fluid consumed. The amount of material used and the volume of waste required for the above can be markedly reduced as compared with those in the conventional container.

Further, in this case, since the container holds the fluid in the container main body and the opening end of the nozzle part is supplied in a state of being sealed by the cap, the cap is nozzle-operated by the cap locking device. The cap is locked at the open end sealing position, and the cap is loaded in a reinforcing case in which the container body and the root of the nozzle can be opened and closed, and the root of the nozzle is in a predetermined position with respect to the reinforcing case. When the reinforcing case is closed in the state set to, the cap locking action of the cap locking device is released by the closing motion of the reinforcing case. The flexible and expandable / contractible container body part is loaded into a rigid reinforcing case, and there is no risk of being inadvertently pressed from the outside, and the nozzle part is reinforced at its root part. To over scan is set to a predetermined position,
The combination of the reinforcing case and the nozzle allows the cap to be removed only after the fluid supply device is shaped as if it were one rigid container, so it is flexible and expandable and contractible. Even if a container having a container body is used, the inconvenience of overflow contamination of the fluid due to inadequate handling of the container is reliably avoided.

[0009]

According to one detailed embodiment of the container of the present invention having the above-mentioned constitution, the cap is attached to the open end of the nozzle portion by mutual screw engagement,
The cap locking device may be means for selectively preventing relative rotation between the cap and the nozzle part at a position where the opening end of the nozzle part is sealed.

Further, in that case, the nozzle portion is provided with a collar portion, and the cap has an annular peripheral edge portion which abuts the collar portion when the opening end of the nozzle portion is sealed, and the cap lock is provided. The locking device has a locking piece that is movably attached to the collar portion and that engages with an annular peripheral edge portion of the cap that is in contact with the collar portion from the inside in the radial direction to prevent rotation of the cap. You can do it.

Further, in that case, inner teeth may be formed on the annular peripheral portion of the cap, and the locking piece may have teeth that mesh with the inner teeth.

Further, in that case, the locking piece is provided so as to penetrate through the collar portion in the axial direction, and the portion of the reinforcing case protruding from the side opposite to the side where the cap contacts. It may have a drive engaging portion which is engaged with a part and is driven inward in the radial direction with respect to the collar portion by the closing movement of the reinforcing case.

Further, in that case, the locking pieces may be provided as a pair symmetrically with respect to the central axis of the nozzle portion.

In the stiff and openable reinforcing case into which the container body of the container and the root of the nozzle are loaded, the root of the nozzle is predetermined with respect to the reinforcing case. It may be configured to have a cap locking releasing means which is set to the position and which releases the cap locking action of the cap locking device by the closing movement when the case is closed.

In this case, the main part of the reinforcing case is composed of a tubular body which is divided in half in the vertical direction, and two half tubular bodies forming each half of the tubular body are provided at one edge in the vertical direction. It may be configured to be openable and closable by being pivotally connected to each other.

Nozzle section 20 connected at position 6 and nozzle section 20
Has a cap 24 that closes the open end 22 and a cap locking device 30 that includes a collar portion 26 provided on the nozzle portion 20 and a pair of locking pieces 28 slidably attached to the collar portion 26. The collar portion 26 may be formed separately from the container body portion 19 and attached to the nozzle portion 20 by a suitable joining means such as an adhesive or heat welding, or the nozzle portion 20.
Alternatively, the nozzle portion 20 and the container body 19 may be integrally molded with a synthetic resin material.

The nozzle portion 20 has an external thread 3 at its open end.
2 is formed. The cap 24 has a cylindrical side wall portion 3.
4 and a disk-shaped end wall 36, a cylindrical boss 38, and a rib 40, which is an integrally molded product made of synthetic resin. The boss 38 is fitted with the outer screw 32 of the nozzle 20. Inner threads 42 that fit together are formed, and inner teeth 44 are formed along the inner periphery of the open end of the cylindrical side wall 34.

The brim portion 26 is provided with a pair of rectangular holes 46 passing through it in the thickness direction. A pair of locking pieces 2
Reference numeral 8 includes a neck portion 48 having a rectangular cross section fitted into the rectangular hole 46 of the collar portion 26 so as to penetrate therethrough, and a tooth 49 which is connected to one side of the neck portion 48 and meshes with the inner teeth 44 on the peripheral edge of the cap 24. A top member having a leg portion 50 and a triangular plate-shaped head portion 52 integrally connected to the other side of the neck portion 48, and the neck portion 48 fits into the rectangular hole 46 of the collar member to form a leg. It is attached to both sides of the collar portion 26 by pressure with the portion 50 and the head portion 52, and the neck portion 48 has a rectangular hole 4.
It is possible to slide inward and outward in the radial direction with respect to the collar portion 26 within a range in which it can move along 6. The locking piece 28 has teeth 4 of the leg 50 when the neck 48 is fully displaced radially outward relative to the collar 26 along the rectangular hole 46 as shown in FIG.
9 is completely engaged with the inner teeth 44 of the cap. The locking piece 28 has a leg portion 50 and a head portion 52.
Since the tongue is pressed against both sides of the collar portion 26 by the elasticity of the neck via the neck portion 48, the locking piece 28 is attached to the collar portion 26 as shown in FIG. When it is biased outwards in the radial direction, it is held fairly strongly by the frictional contact between the flange portion 26 and the flange portion 26, and this is held in the rectangular hole 46 in the locking piece 28 as described later.
The locking position shown in FIG. 4 is held stably unless a radially well-aligned force pushing it radially inwardly against the collar portion 26 is applied.

When the locking piece 28 is in the locking position shown in FIG. 4, its teeth 49 mesh with the inner teeth 44 of the cap, so that the cap 24 is rigidly connected to the collar portion 26 and it. The nozzle 24 is locked so as not to rotate with respect to the nozzle portion 20 and thus the cap 24 is attached to the nozzle 2
It is locked in a position to seal the open end 22 of zero. Accordingly, the pair of locking pieces 28 are biased along the rectangular hole 46 to a position radially inward of the collar portion 26, and the locking piece teeth 49 are brought into a position where they do not mesh with the inner teeth 44 of the cap. Ink is filled in the container body 12 without the 24 attached, and then the cap 24 is attached to the nozzle 20 by the inner screw 38 of the boss 32.
When the open end 22 of the nozzle portion 20 is sealed by the cap 24, the pair of locking pieces 28 are positioned radially outward with respect to the collar portion 26 as shown in FIG. When it is moved and its teeth 49 are engaged with the inner teeth 44 of the cap, the container in the state as shown in FIG. 1 is prevented from being inadvertently removed with the ink filled inside. Not a stable container.

As can be seen from FIG. 4, the cap 24
Is the outer screw 32 of the nozzle portion 20 and the boss portion 38 of the cap.
Due to the screw engagement with the inner screw 42 of the
When the open end 22 of 0 is closed in a sealed state,
The annular end of 4 is preferably designed to just abut the collar 26. Further, the external screw 32 provided on the nozzle portion 20 and the internal screw 42 provided on the boss portion of the cap are provided.
The size and positional relationship between the inner teeth 44 provided on the side wall portion and the teeth 49 of the pair of locking pieces 28 are such that the cap 24 just tightens the opening end 22 of the nozzle portion 20 as described above. When it is determined that the inner teeth 44 of the cap and the teeth 49 of the pair of locking pieces 28 are aligned with each other so as to mesh with each other, the pair of locking pieces 28 are radiused after the rotation for screwing the cap is completed. The engagement of the inner teeth 44 and the teeth 49 should be achieved by driving outward in the direction. However, when the above alignment is not always achieved due to manufacturing error of individual parts, the pair of locking pieces 28 are attached. Cap 2 when driving radially outward
It suffices to apply a slight rotational vibration to 8.
