Description

  The present invention relates to a cap for a bag-like object attached to the opening to open and close the opening of a bag-like object such as a wallet or a bag.

  Generally, a base attached to an opening of a bag-like object such as a wallet or a bag is, for example, disclosed in Patent Document 1, a pair of frame materials that are openably and closably connected to each other, and each of these frame materials. The locking projections are provided, and the locking projections are engaged with each other so that the frame members can be held in a closed state. In this type of base, the locking protrusions can be easily engaged and disengaged simply by picking and twisting, and the items in the bag-like material can be easily taken in and out.

  However, in the conventional base, since the locking projection having the locking function is exposed to the outside as described above, and the degree of freedom in design design is limited by that amount, each has a common shape. It was lacking in novelty. In addition, there is a drawback in that the locking protrusions exposed to the outside are easily caught on clothes and the like.

  In view of the above, an object of the present invention is to provide a base for a bag-like product that can solve the above-described problems, improve the designability, and is excellent in usability.

  In order to solve the above-mentioned problems, the cap for a bag-like object according to the present invention is provided with locking protrusions on a pair of frame members connected to be openable and closable, and these locking protrusions are engaged with each other. In the base for holding the frame material in the closed state, the frame material is provided with a cover material that covers the engaging protrusions engaged with each other.

  Further, the cover material is composed of a pair of cover pieces projecting from each frame material, and these cover pieces are joined together to form a hollow solid in the closed state of the frame material, and the inside of the solid Accommodates the locking projection.

  Further, the pair of cover pieces of the cover material have substantially the same shape.

  Specifically, each of the pair of cover pieces of the cover material is substantially bowl-shaped and is joined together to form a hollow sphere.

  Further, the cover material functions as an opening knob for releasing the engagement of the locking protrusions by twisting the cover material so that the pair of cover pieces are separated from each other.

  In the bag-shaped base in the present invention, when the pair of frame members are closed, the engaging projections engaged with each other are covered with the cover member provided on the frame member. The shape can be freely set, and a novel and excellent design can be achieved as compared with the conventional base in which the locking projection is exposed.

  Further, since the locking projections that are easily caught on clothes and the like are covered with the cover material, it is possible to prevent the clothes and the like from being caught and to improve usability.

  Further, since the cover material has a function as an opening knob for releasing the engagement of the locking projection, the cover material that is fitted to each other is picked and twisted even though the locking projection is covered. Only by this, the engagement of the locking projection can be easily released.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1 and FIG. 2, the base (1) for a bag-like object according to one embodiment of the present invention opens and closes an opening (11) of a bag-like object (10) such as a wallet or bag. Further, it is attached to the opening (11).

  The base (1) includes a pair of frame members (2) and (2) that are connected so as to be openable and closable. The frame members (2) and (2) have, for example, a shape that is curved in a substantially arc shape, and the frame members (2) and (2) are pivoted via connecting shafts (5) and (5) at both ends thereof. It is attached and attached to the opening (11) of the bag-like object (10). In addition, the shape of frame material (2) (2) is not specifically limited, For example, the shape bent in the substantially U shape may be sufficient.

  The pair of frame members (2) and (2) are rotatably connected around the connecting shafts (5) and (5), and the frame members (2) and (2) are brought into contact with each other to form a bag (10). It is possible to switch between a closed state in which the opening (11) of the bag is closed and an open state in which the opening (11) of the bag-like object (10) is opened by separating the frame members (2) and (2). Has been.

  As shown in FIG. 2 and FIG. 3, locking projections (3) and (3) are integrally projected on the middle part of the pair of frame members (2) and (2), respectively. The frame members (2) and (2) are held in the closed state by engaging the projections (3) and (3) with each other.

  Further, the cover material (4) for covering the locking projections (3) and (3) engaged with each other corresponds to the locking projections (3) and (3) in the frame materials (2) and (2). Is provided. That is, the cover material (4) is composed of a pair of cover pieces (6) and (6) protruding from the respective frame materials (2) and (2). 2) In the middle part of (2), it is integrally projected so as to surround the locking projections (3) and (3).

  The shape of the cover pieces (6) and (6) is such that a hollow sphere is divided into wavy shapes. That is, the cover pieces (6) and (6) have substantially the same shape as each other, and are formed in a substantially bowl shape by hollowing out the inside of each hemisphere. In the closed state of the frame members (2) and (2), the cover pieces (6) and (6) form hollow spheres by combining the divided surfaces with each other, as shown in FIG. The engaged locking projections (3) and (3) are concealed while being accommodated inside the sphere.

  In addition, the cover pieces (6) and (6) are not limited to those forming a hollow sphere by being combined with each other as described above, and may be, for example, a hollow cube or other shapes. .

  In addition, when the frame members (2) and (2) are in the closed state, the divided surfaces of the cover pieces (6) and (6) are brought into contact with each other as shown in FIG. A predetermined angular position is laterally displaced with respect to the contact surface. Thereby, the engagement of the locking projections (3) and (3) can be released by twisting the cover material (4) so that the pair of cover pieces (6) and (6) are separated from each other. ing. That is, the cover material (4) has a function as an opening knob for releasing the engagement of the locking protrusions (3) and (3).

  The cover pieces (6) and (6) of the cover material (4) are brought together without engaging each other when the frame materials (2) and (2) are closed. That is, since the cover material (4) itself does not need to have a locking function, the design of the cover material (4) is improved without being restricted by the design by providing the locking function. The designability of (1) can be improved.

  In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of this invention.
