Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a cap for a container and a supporting stand for a capped container that supports the capped container in an inverted state.

<Prior art and its problems> Conventionally, viscous foods such as mayonnaise and ketchup are often served in flexible plastic containers, and when using them, it is difficult to press the containers. and squeeze out the contents. Generally, this type of squeeze container is free-standing, with the entrance and exit for the contents located at the top, and the contents located at the bottom of the container. In this state, when taking out the contents of the container, it is necessary to press the side of the container or hold the container itself upside down for a while to move the contents close to the entrance. This is a troublesome operation, especially when there is little remaining content.

In order to avoid this, the container may be kept in an inverted state with its entrance facing downward, with the contents located on the entrance/exit side, but generally this type of container cannot stand on its own in an inverted state. Therefore, a support stand for supporting the container in an inverted state has been devised, and is disclosed in, for example, Japanese Utility Model Publication No. 53-33735. The device disclosed in Utility Model Publication No. 53-33735 has an inverted conical cylindrical portion formed in the center of the pedestal, and the cylindrical portion has a slit (divided groove) so that the diameter can be expanded or contracted.
A threaded groove is provided on the outer peripheral surface of the cylindrical part, and a nut (fastening ring) is screwed into the threaded groove of the cylindrical part.

In this support stand, the lid of the container is inserted into the cylindrical part, and by tightening the nut, the diameter of the cylindrical part is reduced and the lid is held and fixed within the cylindrical part, and the pedestal holds the container in an inverted state. It can be supported by However, although this support stand can securely hold the lid of the container because it is tightened with a nut, there are problems in that the shape of the cylindrical part becomes complicated, the number of parts increases, and the cost increases.

Furthermore, in Japanese Utility Model Publication No. 54-30280, a concave portion is formed at the bottom of a squeeze container made of a thin synthetic resin film, and a female screw hole of a protrusion protruding from the center of the concave portion is screwed into a suction cup to form a concave portion, or a concave portion is formed at the bottom of a squeeze container made of a thin synthetic resin film. discloses a squeezing container with a suction cup that can be replaced with a cap and screwed together.

However, in this case, in order to make the container stand on its own in an inverted state, it is necessary to replace the cap and suction cup, which is troublesome.Also, although the container can be adsorbed to the ceiling surface in an inverted state, there is a recess in the bottom of the container. Since it is necessary to form a protrusion and a protrusion protruding from the center of the protrusion, there is a problem in that the cost is high.

In view of these circumstances, the present invention provides a cap that allows the support stand to be easily attached and removed, and a support stand for containers with caps that can be attached to the quilt knob to support the capped container upside down and also allow the cap to be opened and closed with the cap attached. The purpose is to provide

Means for Solving the Problems> The structure of the cap according to the present invention that achieves the above object is as follows:
The cap is screwed into the opening of the container body, and is characterized by having a thread formed on its outer peripheral surface in the opposite direction to the screwing direction, and supporting the container with the cap =
4- The structure of the stand is a support stand for inverting a container to which a cap is attached, which has a thread formed on its outer circumferential surface in the opposite direction to the direction of screwing into the opening of the container body, and is a plate-shaped support. A cylindrical holding cylinder protrudes from the upper surface of the base plate, and the holding cylinder has an inner diameter into which the cap can be inserted, and an engaging portion on its inner peripheral surface that can engage with the thread. It is characterized by being provided with.

As mentioned above, there has never been a cap in which a thread in the opposite direction is formed on the outer circumferential surface of the cap.

Naturally, the thread formed in the protrusion of the width of the concave portion provided at the bottom of the container disclosed in the above-mentioned Japanese Utility Model Publication No. 54-30286 is not a reverse thread. In the present invention, as described above, by forming a thread on the outer circumferential surface, attachment and detachment of the support base is made easy and reliable, and by making the thread in the direction opposite to the screwing direction of the cap, the support base is attached. It is now possible to open and close the cap.

The thread formed on the outer circumferential surface of the cap may be groove-like or convex-like. On the other hand, the engaging part formed on the inner circumferential surface of the holding cylinder part of the support base may be any member as long as it can engage with the thread, and if the thread is in the form of a groove, it may be a convex thread or a locking protrusion. , and when the thread is convex, it is a grooved thread.

The thread of the cap may be less than one circumference, and in this case it may be an L-shaped groove. Furthermore, contrary to what has been described above, a groove-like thread may be formed on the holding cylinder portion of the support base, and a locking protrusion may be provided on the outer peripheral surface of the cap.

Function: When the cap is pushed into the holding cylinder part of the support stand in the opposite direction to the direction in which it is screwed into the container, the engaging part formed on the inner peripheral surface of the holding cylinder part engages with the thread on the outer peripheral surface of the cap. However, the cap cannot be removed from the holding cylinder. Therefore, when the cap is attached to the container, the container is stably supported by the support plate when the cap is turned upside down with the support plate facing down. Further, since the support base is engaged in a direction opposite to the direction in which the cap is screwed into the container, the cap can be opened and closed with the support base attached.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

1 and 2 show a cap according to an embodiment of the present invention. As shown in these drawings, a male thread 1 is formed at an entrance 12a for contents opened at the top of a squeezing container body 12 made of a flexible material such as plastic.
A male thread 12 is provided on the outer peripheral surface of the cap 13 screwed onto the cap 2b.
A thread 13a is formed that rotates in the opposite direction to b. The threads 13a of these caps 13 are groove-shaped, and FIG. 1 shows an example in which the threads 13a are formed from the top to the middle of the cap 13, and FIG. 2 shows an example in which the threads 13a are formed throughout the cap 13. Note that a knurling 13b is also formed on the outer peripheral surface of the cap 13 to prevent slipping.

An example of the support base of the present invention that engages with the cap 13 of such a container 11 is shown in FIG.

As shown in the figure, a support base 14 and a disk-shaped support plate portion 15 are provided.
It has a shape in which a cylindrical holding tube part 16 protrudes from the center of the upper surface, and is integrally molded from plastic. The support base plate part 15 has a flat lower surface and can be stably placed on a flat surface such as the top surface of a table, and its area is large enough to prevent the container 11 from falling over when supported, as will be described later. It's sato. On the other hand, the holding cylinder part 16 has an inner diameter that allows the above-mentioned cap 13 to be inserted, and an engaging part 16a that engages with the thread 13a of the cap 13 on the inner peripheral surface thereof.
is formed. Although the engaging portion 16a is a convex thread in this example, it may be a locking protrusion as shown in FIG.

When using such a support stand 14, the cap 13 screwed onto the container body 12 is inserted into the holding cylinder part 16 by counterclockwise screw rotation. Then, the engaging portion 16a engages with the thread 13a, and the support base 14 is tightly and securely held on the cap 13. Therefore, after that, as shown in FIG.
If the container 11 is placed face down, the container 11 will be supported upside down.

In addition, in consideration of the case where the support stand 14 is removed from the cap 13 after use, the depth of the holding cylinder part 16 is made as shallow as possible, and the fifth
It is better to make a larger in the figure.

The thread 13a formed on the outer peripheral surface of the cap 13 may be less than one round as shown in FIG. Alternatively, it is a locking protrusion. Further, in this case, the thread 3a of the cap 13 may simply be an L-shaped groove as shown in FIG.

Further, the thread 13a of the cap 13 may have a convex shape as shown in FIG. 8 or a locking protrusion as shown in FIG. 9. In this case, the engaging portion 16a of the holding cylinder portion 16 has a groove shape.

<Effects of the Invention> As specifically explained above in conjunction with the embodiments, according to the present invention, the support base can be easily and securely attached to and removed from the cap, and the container can be supported in an inverted state.
Moreover, the cap can be opened and closed with the support stand attached.
