Description

[Detailed description of the invention] [Industrial field of application] This invention is a method of filling highly viscous foods such as mayonnaise and ketchup, adhesives, paints, paints, and other viscous substances, with the extrusion port side facing down. This invention relates to an inverted extruded container that can be held upside down.

[Prior Art] Conventionally, this type of inverted extrusion container has been disclosed, for example, in Japanese Utility Model Application Publication No. 52-73134 and Japanese Utility Model Application Publication No. 1983-1999.
The one described in Publication No. 33735 is known.

[Problems to be solved by the invention] Extrusion containers are used to fill viscous substances that have high viscosity and easily solidify, such as foods such as mayonnaise and ketchup, or adhesives, paints, and paints.
In order to be able to extrude and use the required amount of contents quickly and easily, it is desirable to keep the container inverted at all times with the extrusion port facing down.

By the way, in the conventionally known extruded container for inverting, the pedestal that supports the container body in an inverted shape is a cylindrical part into which the cap part of the container body is inserted, and the inner circumference of the cylindrical part is Since the cap part of the container body is supported by elastic pressure or by the cylindrical part itself, the height of the cylindrical part of the base must be adjusted to stably support the container body when it is inverted. The vertical length must be approximately the same as the cap portion of the container body, and the base cannot be formed into a flat plate shape.

If the height of the pedestal is large as in the past, it is not only inconvenient to package it as an accessory to the container body, but also the cap part of the container body when inverted is This is undesirable in terms of keeping the cap portion clean, which tends to get dirty during use.

In view of solving the problems of the conventional ones, the present invention is capable of stably maintaining the inverted posture of the container body even if the inversion aid that supports the container body in an inverted posture is made into a flat plate. It is an object of the present invention to provide an inverted extruded container in which a large part of the cap part of the container body is always exposed and the cleanliness of that part can be maintained.

[Means for solving the problem] The present invention is configured as follows as a technical means for achieving the object.

That is, the structure consists of a container body with a filling outlet formed at one end and a cap detachably attached to the extrusion outlet, and a container body with a cap that has a larger outer diameter than the container body and is fitted on the end face side of the cap. In the extruded container for inverting comprising an inverting aid, the inverting aid is formed into a flat plate shape, and a rubber O-ring is tightly abutted on the outer peripheral surface of the cap of the container body at the fitting part of the inverting aid. This is an extruded container for inversion having an elastic anti-slip member formed by the above method.

Note that a plurality of radially arranged protrusions may be formed on the fitting portion of the inversion aid.

[Function] As described above, the push-out container for inverting according to the present invention has a rubber O-ring that contacts the outer circumferential surface of the cap of the container body in the fitting part of the inverting aid. When fitted into the cap of the container body, the outer peripheral surface of the cap is held through a rubber O-ring over its entire circumference, and the inversion aid is fixed to the cap.

Therefore, by standing the container body with the inversion aid facing down, the container body can be maintained in an inverted position.

[Example] An embodiment of the present invention will be described with reference to the drawings.

The drawing shows an example of an inverted mayonnaise extrusion container. Reference numeral 1 denotes a container body, which is made of flexible plastic and has an extrusion port 2 opened at one end, and a cap 3 is detachably attached to the extrusion port 2. . A large number of grooves 4 are formed on the outer peripheral surface of the cap 3 to prevent slipping.

5 is a handstand aid, and this handstand aid 5
The inverted support portion 6 has a diameter larger than that of the cap 3, and a fitting portion 7 corresponding to the end surface of the cap 3 is formed. The inverted support portion 6 has a peripheral edge 6a formed higher than the inner portion, and a knurl 6b for preventing slipping is formed on the outer peripheral surface. Further, the fitting part 7 of the inversion aid 5 includes a stopper part 7a which is brought into contact with the end surface 3a of the cap 3;
An inner wall 7b and a recessed step 7c are formed on the outer periphery of the end surface of the cap 3, and a rubber O-ring 8 is fitted into the inner peripheral surface of the recessed step 7c. This O-ring 8 forms an elastic anti-slip member. Note that the inner wall 7 of the fitting portion 7
A protrusion 9 is formed on b to engage with the groove 4 of the cap 3. The number of these protrusions 9 is smaller than the number of grooves 4 of the cap 3, for example, three protrusions are provided every 120 degrees.
The tip 9a is formed into a curved shape.

In the device configured as described above, the inversion aid 5 has its fitting portion 7 attached to the cap 3 of the container body 1.
The outer peripheral surface of the cap 3 is held tightly over the entire circumference by the elasticity of the rubber O-ring 8. When the container body 1 is stood up with its extrusion port 2 facing down, the peripheral edge 6a of the inversion aid 5 fitted in the cap 3 of the container body 1 is stabilized by the inversion support part 6 which is higher than the inside. Posture is maintained.

Even if the inversion aid 5 that supports the container body 1 in an inverted position is shaped like a flat plate, the inverted posture of the container body 1 can be stably maintained. A large part of the cap 3 of the container body 1 is always exposed, and that part can be easily kept clean.

Furthermore, since the fitting part 7 of the inversion aid 5 is provided with an elastic O-ring 8 made of rubber, it is easy to fit the inversion aid 5 into the cap 3.
Moreover, it is possible to maintain a tightly fitted state over the entire circumference of the cap 3. Further, even if the outer diameter of the cap 3 and the shape of its outer circumferential surface are different, the elasticity of the rubber O-ring 8 ensures that the cap 3 is in a fitted state, so that an existing extruded container can be used as an inverted extruded container as it is. In particular, since the fitting part 7 is provided with a rubber O-ring 8, even if the length of the protrusion into the fitting part 7 increases gradually from the bottom to the top, the cap 3 is Support is certain. Furthermore, since the inner wall 7b has the protrusion 9, the cap 3 is also strongly fixed in the rotational direction.

Therefore, the cap 3 of the container body 1 can be opened and closed by turning the inversion aid 5 while it is fitted.

In addition, in the inversion aid 5, if the diameter of the recessed step 7c is set to 1.01 to 1.08 times the diameter of the inner wall 7b, the anti-slip member 8 can be fitted into the recessed step 7c well, and the cap 3 can be When the inversion aid 5 is removed after fitting, the rubber O-ring 8 does not come off from the inversion aid 5 unnecessarily.

[Effects of the invention] Since the present invention is configured as described above,
Even if the inversion aid that supports the container in an inverted position is in the form of a flat plate, it is possible to stably maintain the inverted position of the container, and the inversion aid is made in the form of a flat plate so that most of the cap of the inverted container is always exposed. This has the effect of keeping the area clean.
