JP5080772B2 - Container with lid - Google Patents

Description

  The present invention relates to a container with a lid, and reliably positions the lid with respect to the main body portion.

  In recent years, containers having cream-like cosmetics and the like having various shapes such as squares and triangles have been put on the market from the viewpoint of differentiation from other products.

In this type of container, the lid body generally has the same shape as the main body portion of the container. After the lid body is attached, the lid body stops at a predetermined position of the main body portion of the container. Thus, a positioning projection is provided (for example, see Patent Document 1).
JP 58-177358 A

By the way, the positioning protrusion provided on the conventional container as described above is positioned by the protrusion provided on the inner side of the lid getting over the protrusion provided on the main body portion of the container. The contact pressure at that part is high, and there is a risk that the projection will be worn out at an early stage, making it impossible to accurately position the lid relative to the main body of the container. In order to solve such problems, various attempts have been made to reduce the contact pressure between the protrusions, such as elastically holding the protrusions using an elongated arm. There was a problem and there was still room for improvement.

  An object of the present invention is to propose a container with a lid that can be accurately positioned with respect to the main body of the container until the contents are used up without causing damage to the constituent members.

The present invention is a container with a lid provided with a main body portion having a space region for storing contents, and a lid body screwed to the mouth of the main body portion to seal the space region,
Providing a convex portion in at least one place on the outer wall of the main body portion,
At least one location on the inner wall of the lid body is elastically held via a soft member provided on the back surface of the lid body, and the lid body is positioned relative to the main body portion by overcoming the projection in the screwing completion area of the lid body. A container with a lid, characterized in that a small protrusion is provided.

  In the container with a lid configured as described above, the lid body has a double structure of an inner cap that is screwed to the mouth portion of the main body portion and an outer cap that covers the inner cap and includes a small protrusion on the inner cap. Things can be applied. Further, as the above-mentioned soft member, an elastic material such as an elastomer or rubber is applied.

Since the small protrusions so as to resiliently held via a flexible member, maintain projections and small projections contact pressure can be alleviated and becomes its wear in mutual decreases positioning functions of the small protrusions for a long time Is done.

  If a soft member is arranged between the small protrusion and the lid, the small protrusion is always in contact with the soft member even if the small protrusion is pressed toward the inside of the lid when the small protrusion gets over the convex portion. The member connected to it is not damaged.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIGS. 1 (a) and 1 (b) show an embodiment of a container with a lid according to the present invention. In FIG. 1, number 1 is a main body part having a space area m for storing contents, and 2 is a main body part. 1 is a lid that is screwed to the mouth portion 1a to seal the space region m.

  The lid 2 includes an inner cap 2a having a threaded portion that is screwed to the mouth portion 1a of the main body portion 1, and an outer cap 2b that is fitted and held on the inner cap 2a and forms a gap L at the lower end opening. This is shown as an example.

  Reference numeral 3 denotes a stopper that is integrally provided on the outer wall of the main body portion 1 and stops the rotation of the lid 2 by contacting a small protrusion (4) described later.

  Reference numeral 4 denotes a small protrusion provided at the lower part of the inner wall of the lid body 2 for positioning the lid body 2 with respect to the main body portion 1 over the convex portion (7) in the screwing completion region of the lid body 2. The small protrusions 4 are shown as one example provided at each opposing position (may be one), and the main parts thereof are elastic arms on both sides of the small protrusions 4 as shown in FIGS. 4a and 4b are formed so that the small protrusion 4 can be displaced in the radial direction of the container.

  Further, 5 is a soft member arranged from the back surface of the small protrusion 4 to the elastic arms 4a and 4b, 6 is a holder for holding the soft member 5 and the small protrusion 4 and fixing them to the opening of the outer cap 2b, and 7 is a main body part. 1 is an example in which two protrusions are provided integrally at the lower part of the outer wall of the outer wall, and two may be provided at opposing positions.

  The lidded container having the above-described configuration can be easily displaced when the small protrusion 4 gets over the convex portion 7, so that the contact pressure between them does not increase, so wear is low and accurate positioning is possible for a long time. Not only can this be performed, but the soft member 5 is located on the back surface thereof, so that excessive force does not act on the elastic arms 4a and 4b to damage them.

  In the above configuration example, the case where the small protrusion 4 is provided on the lid body 2 and the convex portion 3 is provided on the outer peripheral wall of the mouth portion 1a of the main body portion 1 has been described, but the small protrusion 4 is provided on the outer peripheral wall of the mouth portion 1a. Further, the convex portion 7 may be provided on the lid 2, and this point can be changed as appropriate.

Further, the lid 2 is shown as a combined structure of two members of the inner cap 2a and the outer cap 2b, but the lid 2 may be constituted by a single member. Especially when configuring the lid 2 by 2 members, it is possible to occlude the gap by placing the soft member 5 in the gap L, good appearance in design.

  FIG. 4 shows another embodiment of the container according to the present invention. The elastic arms 4a and 4b for elastically displacing the small protrusions 4 can form a rupture portion h separated at least at one place as shown in the figure in order to increase the amount of displacement.

  As described above, the soft member 5 is preferably made of an elastic material such as an elastomer or rubber, and can be formed by insert molding. However, the soft member 5 may be incorporated later as a separate member from the holder 6.

  As the container, a container made by injection molding or blow molding, a tube type container made by extrusion molding, or the like is applied.

  It is possible to provide a container with a lid that can perform accurate positioning over a long period of time without causing damage to members.

It is the figure which showed embodiment of the container with a lid according to this invention, (a) is a top view, (b) is the figure which showed the right half of the side surface with the cross section. FIG. 2 is an enlarged cross-sectional view showing a main part of the lidded container shown in FIG. FIG. 2 is an enlarged cross-sectional view showing a main part of the lidded container shown in FIG. It is the figure which showed other embodiment of the container with a lid according to this invention about the principal part.
