JP7482595B2 - Container with lid - Google Patents

Description

The present invention relates to a container with a lid, in particular a container with a screw-on lid.

For containers such as jar-type containers that have a wide opening for removing the contents, it is common to seal the container body with a screw-on lid, as shown in Patent Document 1.

However, with this type of container, when you start to open the lid or when you close the lid, it is not easy to tell whether the lid has transitioned to a state where it is just starting to open or has reached a state where it is completely closed, and there is still room for improvement in this regard.

The objective of the present invention is to propose a container with a lid that allows the user to know the open/closed status of the lid not only by the sensation transmitted to the fingers when opening or closing the lid, but also by the sound that is produced.

The present invention provides a container with a lid, which is screwed to a threaded portion formed on an outer peripheral surface of an opening of a container body and hermetically holds the container body,
a rib is provided on an outer peripheral surface of the opening of the container body, and a protrusion is provided on an inner peripheral surface of the lid body opposite the rib, the protrusion making a sound when it overcomes the rib and returns to its original position when the installation of the lid body is completed and when removal of the lid body is started;
The rib is an annular rib having a pitch equal to the thread pitch of the thread portion, provided below the thread portion in a direction along the thread portion , and having a mountain-shaped cross section with inclinations on both sides of a vertex,
The container with lid is characterized in that the protrusion is made of a thin tongue piece that is elastically deformable .

The container with lid of the present invention not only provides the user with the sensation of the protrusions climbing over the ribs when opening or closing the lid, but also produces a sound at the same time, allowing the user to know with certainty that the lid is open or closed.

In addition, in the case of a container with a lid according to the present invention, when the lid is in the closed state, the protrusion functions as a stopper that prevents the lid from rotating, so the lid will not easily come loose even if an unexpected force acts on the lid due to the container being dropped or coming into contact with another object.

In addition, with the lidded container of the present invention, the ribs and protrusions are arranged in a direction that follows the threads at a pitch equal to the thread pitch, and the ribs are annular ribs and the protrusions are thin, elastically deformable tongues, so that a sound can be reliably produced when the lid is opened or closed.

Furthermore, in the case of the container with lid of the present invention, the rib is configured to have a mountain-shaped cross section with a slope on both sides of the apex, so the protrusion moves along the slope while abutting against the rib, allowing the lid to rotate smoothly.

FIG. 2 is a view showing the inner peripheral surface of the lid body as viewed along the line AA in FIG. 1. 13A and 13B are diagrams showing deformation of the protrusions at the start of removing the lid body, in relation to the main parts. 13 is a diagram showing a deformation state of a protrusion at a main part when the installation of the lid body is completed. FIG. FIG. 2 is an enlarged view of a main portion of a container with lid according to the present invention.

The present invention will now be described in more detail with reference to the drawings.
Fig. 1 is a schematic diagram showing a side view of an embodiment of a container with lid according to the present invention (a cross-section of the right half with respect to the center line), and Fig. 2 is a diagram showing the inner peripheral surface of the lid as viewed along arrows A-A in Fig. 1. Note that the entire container with lid according to the present invention, including the lid, can be made of synthetic resin.

The reference numeral 1 in the figure denotes a container body having a filling space M for the contents. The container body 1 is composed of a bottom wall 1a and a peripheral wall 1b that is connected to the edge of the bottom wall 1a and stands up, and that cooperates with the bottom wall 1a to define the filling space M for the contents on the inside. An opening 1c is formed in the upper part of the peripheral wall 1b for removing the contents.

2 is a threaded portion provided on the outer peripheral surface of the opening 1c, and 3 is a lid that holds the container body 1 in the opening 1c in a sealed manner. The lid 3 is composed of a top plate 3a located on the upper surface of the opening 1c and a peripheral wall 3b that is suspended from the edge of the top plate 3a and surrounds the opening 1c, and the inner peripheral surface of the peripheral wall 3b is provided with a threaded portion 3c that can engage with the threaded portion 2 provided on the outer peripheral wall of the opening 1c.

Also, 4 is a rib provided on the outer circumferential surface of the opening 1c below the threaded portion 2. The rib 4 is an annular rib that goes around the opening 1c. The rib 4 is preferably configured in a horizontal position (diametrically outward) with a mountain-shaped cross section with inclinations 4b and 4c on either side of the apex 4a, and is provided at a pitch equal to the thread pitch P of the threaded portion 2 and in a direction along the threaded portion 2. The rib 4 may be configured as a plurality of protrusions that are intermittently arranged in a ring shape around the opening 1c at intervals, or a single protrusion (short circumferential rib). When a rib 4 consisting of a plurality of protrusions or a rib 4 consisting of a single protrusion is used, these are provided at a position that reliably abuts against a protrusion (symbol 5) described later when the lid 3 is closed.

Reference numeral 5 denotes a protrusion provided on the inner peripheral surface of the peripheral wall 3b of the lid 3, with a pitch equal to the thread pitch P of the thread 3c, and oriented along the thread 3c. The protrusion 5 is provided on the peripheral wall 3b of the lid 3 so as to face the rib 4, and functions as a sound-producing member that makes a sound by climbing over the rib 4 when the installation of the lid 3 is completed and when removal of the lid 3 begins. The protrusion 5 is shown here as an example of a thin tongue piece that can be elastically deformed, but is not limited to the tongue piece shown in the figure as long as it can reliably produce sound. The protrusion 5 can be provided so as to be perpendicular to the axis O of the lid 3 (see FIG. 2) (horizontal arrangement).

If the circumferential length H of the protrusion 5 (see Figure 2) is less than 2.0 mm, there is concern that it may not be strong enough and may break, while if it exceeds 8.0 mm, it is expected that the protrusion itself will be difficult to deform and will have difficulty producing sound. For this reason, in the present invention, the circumferential length H of the protrusion 5 is preferably set to approximately 2.0 to 8.0 mm. It is best to set the circumferential length H of the protrusion 5 to 4.0 mm. Furthermore, 6 is a seal member (packing) provided on the back surface of the top plate 3a of the lid 3.

Figure 3 shows the deformation of the protrusion 5 at the start of removing the lid 3, and Figure 4 shows the deformation of the protrusion 5 at the end of installing the lid 3.

When the lid 3 of the container with lid of the present invention is opened or closed, the protrusion 5 passes over the rib 4 and deforms as shown in Figs. 3 and 4, so that not only is there a sensation in the fingers, but also a sound is generated, allowing the user to reliably grasp the opening and closing status. In addition, when the lid 3 is closed (see Fig. 1), the lid 3 will not loosen unless the protrusion 5 passes over the rib 4, which has the advantage that the lid 3 will not be opened accidentally.

In the embodiment of the present invention, the rib 4 is provided on the outer peripheral surface of the opening 1c of the container body 1, and the protrusion 5 is provided on the inner peripheral surface of the peripheral wall 3b of the lid 3. However, it goes without saying that the rib 4 may be provided on the inner peripheral surface of the peripheral wall 3b of the lid 3, and the protrusion 5 may be provided on the outer peripheral surface of the opening 1c of the container body 1. The ribs 4 and protrusions 5 may also be provided in multiple positions along the top and bottom.

Figure 5 shows the overlap (engagement) L, thickness t, and length W of the protrusion 5 with respect to the rib 4. In order to reliably elastically deform the protrusion 5 when the lid 3 is opened and closed, in addition to setting the circumferential length H to about 2.0 to 8.0 mm as described above, it is preferable to set the overlap L to about 0.2 to 2.0 mm, the thickness t to about 0.5 to 1.5 mm, and the length W to about 1.5 to 4.0 mm. In particular, if the length W is less than 1.5 mm, it will be necessary to protrude the rib 4 radially outward, which may narrow the gap between the inner surface of the lid 3 and the rib 4, making it difficult to rotate the lid 3 smoothly. On the other hand, if the length W exceeds 4.0 mm, the gap between the lid 3 and the outer peripheral surface of the opening 1c will become large, and there is a concern that the rattle of the lid 3 will increase. For this reason, it is preferable to set the length W of the protrusion 5 to about 1.5 to 4.0 mm. It is best to set the overlap L to 1.0 mm, the thickness t to 0.8 mm, and the length W to 3.0 mm.

The container with a lid according to the present invention can also be applied to a cap that is screwed onto the neck of a bottle or a screw-on cap that connects the pump and container of a container with a pump, and is not limited to jar-type containers.

The present invention provides a container with a lid that allows the user to clearly know whether the lid is open or closed not only by the sensation transmitted to the fingers, but also by the sound.
