Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a lid for an oval container that is safe and less likely to come off even if it is inadvertently pressed to some extent.

(Prior Art) As with the present invention, a conventional lid for an elliptical container has a lower part on the outer side in the major axis direction of the elliptical neck 4 of the container.
By locking or releasing the locking of the pair of inner cylinder protrusions 20 of the inner cylinder 15 in the long diameter direction of the oval outer cylinder 14 of 3, the lid body is attached to the finger-shaped neck 4. Although the oval lid body 13 is configured to be attached and detached, the inner cylinder 15
is configured in a cylindrical shape, and the facing distance between the bases of the pair of inner cylinder protrusions 200 and the facing distance between the inner surfaces of the pair of inner cylinders perpendicular to these are configured to be the same, so that the content of the liquid When filled with cardboard boxes and transported or stored, the oval containers are stacked in the short diameter direction, so if the cardboard box is pressed or subjected to impact from the outside, the oval lid will break. Since the body 13 is pressed in the short diameter direction, that is, in the lid opening direction, an accident may occur in which the lid 13 comes off and the liquid inside the container flows out.

(Problems to be Solved by the Invention) The cross-sectional shape of the inner chamber 15 has been devised so that the elliptical lid 13 has a lower part than the pair of protruding steps 8 on the outside in the long diameter direction of the elliptical neck 4 of the container. A pair of inner cylinder protrusions 20 formed on the inner cylinder l5 in the long diameter direction are elastically engaged strongly against release, so that even if the lid body [3] is subjected to some pressure, it can be easily locked. This provides a configuration that does not release the .

(Means for Solving the Problems) The present invention provides a pair of protruding step portions 8 on the outer side lower side in the major diameter direction of the oval neck portion 4 of the container, and an inner cylinder 15 in the major diameter direction of the outer cylinder 14 of the lid body 13. When the pair of molded inner cylinder protrusions 20 are locked or unlocked, the inner cylinder 15 is attached to and removed from the oval neck 4. This lid body for an elliptical container is characterized in that it is an equilateral polygon and the distance between the bases of a pair of inner cylinder protrusions 200 is closer to each other than the inner surfaces of a pair of inner cylinders perpendicular thereto.

(Function) Although the normal inner cylinder 15 is cylindrical, in the present invention, the nuclear inner cylinder 1
5 is an ellipse or scalene polygon, and a pair of inner cylinder protrusions 20
Since the facing distance of the 0 base is made closer than the distance between the inner surfaces of the pair of inner cylinders perpendicular to this, even if the lid is slightly pressed in the opening direction, that is, in the short axis direction of the elliptical outer cylinder 14, the inner cylinder 15 will not move in the long axis direction. Since the inner cylinder 15 is pressed, compared to a conventional inner cylinder in which the inner cylinder 15 is cylindrical, stronger suppression is required in order to crush the inner cylinder 15 and expand the distance between the opposing inner cylinder protrusions 200. Therefore, it will not come off even if some pressure is applied carelessly.

(Example 1) Figure 1 (at (cl) is for explaining one example of implementing the present invention, and Figure 1 (al is the right half cross section in the major axis direction of the lid of the oval container of the present invention. Side view, same (bl is a side view showing the right half cross section in the short axis direction of the lid, same (cl is a rear view of the lid, figure 2 illustrates the oval container that covers the lid) Figure 2 (al is a side view showing the right half cross section in the long axis direction of the container, bl is a side view showing the right half cross section in the short axis direction of the container, same (cl is a side view showing the right half cross section in the short axis direction of the container). Plan view,
Figure 3 is a sectional view of the right half in the major axis direction and the left half in the minor axis direction, showing the oval container in Figure 2 covered with the oval lid in Figure 1.

The lid 13 of the oval container of the present invention shown in FIG. The upper end is connected to this by the ceiling part 17, and the major axis direction of the elliptical outer cylinder part 14 is the major axis direction, and the minor axis direction of the oval external cylinder part 14 is the major axis direction. A connecting lip 19 that connects the inner surface of the outer cylinder part 14 and the outer surface of the inner cylinder part 15 on the center line in the minor axis direction of the outer cylinder part 14 and a container. Vertical groove part 1 on the neck
) to prevent the lid from turning; It has an inner cylinder protrusion 20 to prevent it from falling off, and a sealing ring 18 protruding from the center of the inner surface of the ceiling part 17 to enter the container opening 12 and prevent the contents from flowing out.

The container body 1 to which the lid 13 of the present invention is applied is generally illustrated in Figure 2 (a).
l (as shown in bl (cl), oval body 2
The head part 3 is composed of a neck part 4 and an inclined shoulder part 5, the long and short axes of which are located in similar directions. The neck portion 4 has a true interior 6 surrounding a circular opening 12 at the upper end, and then an overhanging top surface portion 7 that expands downward in the major axis direction of the ellipse. With respect to the axis, it is cut into an r [corner, and below it is a shoulder 5 with a small diameter.
This is the constricted portion 10 that is connected to the constricted portion 10 . In the short axis direction of the ellipse below the true inner part 6, there is an inverted bar-shaped, i-shaped part 9 which is inclined downward toward the constriction part 10 at the lower end, and on the outer surface on the center line in the short axis direction. There is a vertical recessed groove portion 1) into which the twill-shaped strut portion 21 of the lid body is inserted.

The lid body 13 of the present invention shown in Figure 1 is combined with the container body 1 shown in Figure 2.
The state in which the neck 4 is covered is as shown in FIG.
The method of capping is to grasp the outer cylindrical part 14 of the lid body with your fingertips, align the major and minor axis directions of the oval shape with the major and minor axis directions of the elliptical body part 2, and insert it so as to cover the neck part 4 of the container body 1. The pillar part 21 is inserted into the vertical groove part 1) of the neck part 4 so that the long and short diameter directions of the elliptical shapes of the container body 1 and the lid body 13 are aligned, and the lid body 13 is inserted. Inner cylinder protrusion 20 on the inner surface of the inner cylinder part 15
moves down the protruding top surface 7 of the neck portion 4 while expanding elastically, and when it crosses the protruding step portion 8 at its lower end, the inner cylinder protruding portion 20 suddenly elastically contracts and the lower end of the protruding step portion 8 The lid body 13 is firmly fitted to the neck portion 4 of the container body 1.

When attempting to remove the lid body 13 from the neck portion 4, remove the outer cylindrical portion 1 of the lid body 13 as shown in Figure 1 (Cl and Figure 3).
4 in the direction of the arrow P, the lid body cylindrical part 15 is elastically compressed in the major axis direction and expanded outward in the minor axis direction via the connecting lip 19. The inner cylinder protrusion 20 moves to the right in the figure to release the lock with the protruding stepped portion 8', which is the widest part of the neck 4 in Figure 3. The lid can be opened by a simple action of lifting the lid body 13 upwards while in this state.

However, the ease with which the lid 13 can be removed from the neck 4 poses a danger to inadvertent suppressive shocks. In fact, the container body of the elliptical body 2 filled with liquid is covered with an elliptical lid, overlapped in the short axis direction of the ellipse, and filled in multiple rows into a cardboard box for transportation and storage.

At that time, it cannot be guaranteed that a pressing blow in the direction of arrow P will not be inadvertently applied.

The lid 13 of the present invention has a structure that can withstand some pressure or impact and will not become unfitted. That is, in the present invention, as is clear from FIG. It is characterized in that an inner cylinder protrusion 20 is disposed on the inner surface of the portion 15 in the short diameter direction.

Therefore, the inner cylinder part 15 of the lid body 13 of the present invention has a much greater elastic resistance force in the short diameter direction of the outer cylinder part 14, that is, in the direction of arrow P, compared to the conventional circular inner cylinder part.

This is because the elastic resistance when the ellipsoid is suppressed or struck in the longitudinal direction is greater than when the cylindrical body is suppressed or struck in the diameter direction, and therefore it is less likely to be deformed.

(Example 2) Figure 4 shows another example of implementing the present invention in which the outer cylinder part 14 is elliptical and the inner cylinder part 22 is octagonal.
1 is a side view showing a right half cross-section of the outer cylinder part 14 in the major axis direction; bl is a side view showing a right half cross section of the outer cylinder part 14 in the short axis direction;

This example differs from Example 1 only in that the inner cylindrical portion 22 is octagonal, and has the same structure in other respects, and can be fitted into the same shape as the container body 1 shown in Example 1. It matches. What is the inner cylinder part 22? As can be seen most clearly in Figure 4 (cl), the short sides A and A are arranged opposite to each other in the short axis direction of the elliptical outer cylinder part 14, and the long sides H are arranged in the long axis direction of the elliptical outer cylinder part 14. , C are arranged facing each other, two sets of narrow corner parts a, C: 16 holes, a are arranged at the four corners between them at an angle of 45 degrees, and these eight boards Shape material a, c2. ha1ro, a, o, ha,
It is a scalene octagonal cylindrical body in which c2 are connected by a thin connecting portion 231C.

Therefore, the elliptical outer cylinder part 14 of the lid 13 of this example is aligned in the length and breadth directions of the elliptical body part 2, and the central part of the outer cylinder part 14 in the breadth direction is pinched with fingertips from both sides. When pressed lightly, the short diameter direction of the outer cylinder part 14 is crushed and approached, and the connecting lips 19, 1
9 is a short side of the octagonal inner cylinder portion 22; The long sides C and C are pressed from both ends through the narrow corner part 000000 to curve outward in an arc shape using the thin connecting part 23 as a hinge part. In this state, when the lid body 13 is pushed over the neck part 4, the twilled strut part 19 fits into the duty recessed groove part 1) of the neck part 4, and the inner cylinder protrusion part 2o slides on the surface of the protruding top surface part 70 of the neck part 4. It descends and reaches the overhanging stepped portion 8, which is under the eaves of the overhanging top surface portion 7, and is locked therein.

When fitted, the inner cylinder protrusion 20 and the long side C are curved in an arc shape by the widest widest part of the overhanging top surface 7, and the inner cylinder protrusion 2o is curved by the opposing overhang step part 8.
Since the straight sides are locked in an arcuate manner, a stronger fitting force can be obtained than in the case of Embodiment I.

In order to release this lock and open the lid body 13, Example 1
As in the case of
When pressed with the tip of a finger in the direction of
The long sides C and C are pressed from both ends through the 0600 opening and spread outward beyond the maximum widening part of the overhanging top surface part 7, causing the inner cylinder protrusion 2o to separate from the overhanging step part 8, and leaving the container body as it is.] This is done by pulling up the lid body 13 in the direction away from.

When the inner cylinder protrusion 2o is removed from the protruding step part 8, stronger suppression than in the case of the first embodiment is required in order to curve the straight long side part C and C of the inner cylinder protrusion 2o into an arcuate shape.

Therefore, there is resistance to opening the lid, and there is safety in that the lid 13 will not be removed by a slight pressure or impact on the lid 13.

(Effects of the Invention) In the present invention, since the opposing bases of the protrusion 2o that fit into the container neck 4 are disposed on the inner surface of the long side of the oval or polygon, the force required to move the protrusion 2o backward and release the engagement is provided. When containers containing liquid are stored in parallel, the lid 13 will not come loose and there is no risk of liquid leakage even if the lid 13 is inadvertently pressed or hit from the outside. Inner cylindrical portion 15 (or long side C) at the base of protrusion 20 that becomes a fitting portion that occurs in lid 13 that is stacked when only body 13 is stored in an integrated box.
It has the effect of eliminating deformation caused by crushing.
