Description

  The present invention relates to a lid fastener used for a lid of a food container such as a cup snack snack or instant cup noodle, and more specifically, once the lid is opened so as not to leave the container. It relates to the instrument.

  Due to advances in food processing technology, food containers have already been developed and distributed along with instant noodles and snacks. These known food containers are usually provided with a cylindrical paper or plastic container body that is open at the top, and a thin film-like lid that seals the opening of the container body. Then, for example, snack snacks are accommodated in the container body, and the lid body is detachably bonded to the upper surface of the flange portion provided around the upper end portion of the container body by heat sealing.

  When eating instant noodles, peel off part of the lid and pour hot water, then leave it for a predetermined time, but at this time, part of the peeled lid usually leaves the container, Any suitable weight may be placed on the lid.

  Moreover, when eating snacks containing a cup, usually, a part of the lid is peeled off and partially opened, and the snacks are taken out from the opening. In addition, the intaker may not always eat all at once, but may want to eat as much as he wants and keep it as he / she is aware of the calories and the like that the snacks have. In such a case, since the lid body is inferior in obstructive property, there is a possibility that the lid body may be accidentally spilled, which is very inconvenient for carrying a food container. Furthermore, since the lid body is inferior in sealing property, there is also a problem that the snack becomes damp and the taste is lowered.

  Next, conventional techniques related to these problems will be described. For example, Patent Documents 1 to 3 disclose weight lids and holding lids in the related art regarding weights for instant noodle lids. In particular, the weight lid disclosed in Patent Documents 2 and 3 is provided with a timer device that notifies the set time. Furthermore, Patent Document 4 discloses a cup noodle lid stopper in which a substantially H-shaped cut is made in a thin plate formed of plastic.

  In addition, regarding a lid for cup snacks, Patent Document 5 discloses a container with a lid provided with closing means. The closing means includes a fitting portion that is fitted to the container flange portion, and is formed to be rotatable along the circumferential direction of the flange portion.

  However, since the instruments such as the weight lid disclosed in Patent Documents 1 to 3 are simply placed on the lid, it is good to leave the container stationary. When carrying around or carrying a container, there is a possibility that the weight lid may fall, which is unsuitable.

  Further, the lid stopper disclosed in Patent Document 4 has an H-shaped notch that locally sandwiches one location along the outer periphery of the lid body, so that the peeled lid body is entirely disposed in the circumferential direction. I can't stop it. In addition, this lid stopper is configured to be easily detached when it comes into contact with any object in a sudden time signature, and can be said to be unsuitable for carrying or carrying a container.

  In addition, the closing means disclosed in Patent Document 5 is configured to be rotatable in the circumferential direction of the container and to be able to suppress the part where the lid body is peeled off in the circumferential direction as a whole. However, this closing means is originally provided in the food container in advance, and is not designed to be reused for other food containers with different dimensions. It was not suitable for environmental harmony.

Accordingly, the lid fastener can be applied to various food containers, and its versatility is enhanced. In addition, since the flexibility promoting portion is bent in the direction of warping, the outer edge portion acts to give an elastic force to return to the original shape (that is, like a leaf spring). Therefore, when the lid fastener is applied to a food container having a larger size, the flange portion can be appropriately gripped along the outer peripheral direction.

  Further, according to the lid fastener of the preferred embodiment of the present invention, since a message display part is further formed on the lid fastener, a health care alert is urged to an ingestor who eats snacks and the like. This can help prevent overeating.

It is the perspective view which showed the lid fastener which concerns on Example 1 of this invention. It is the top view and sectional drawing which showed the lid fastener which concerns on Example 1 of this invention. It is a figure explaining the deformation | transformation of the lid fastener of Example 1. FIG. It is the top view and perspective view which showed the lid fastener which concerns on Example 2 of this invention. It is the perspective view which showed the lid fastener which concerns on Example 3 of this invention.

Hereinafter, although the present invention is explained based on an embodiment shown in a drawing, the present invention is not limited to the following concrete embodiment at all. In the drawings, the same reference numerals are used for the same or corresponding elements.

(Structure / features of lid fastener of Example 1)
FIG. 1 shows a perspective view of a lid fastener 1 according to Embodiment 1 of the present invention. FIG. 1 also shows a food container 2 for storing a snack confectionery or the like (not shown) and a lid 3 sealed on the upper surface thereof. As shown in the figure, the lid fastener 1 of Example 1 has an opening 11 that can receive the flange portion 2f on the outer periphery of the food container 2, a cross-sectional shape that can be fitted to the flange portion 2f, and the food container 2 The outer edge part 13 which forms the hollow space 12 which can accommodate this, and the flexibility promotion part 14 which promotes a deformation | transformation of the outer edge part 13 are provided.

  Fig.2 (a) shows the top view of the lid fastener 1 which concerns on Example 1 of this invention. As shown in this figure, it can be seen that the outer shape of the outer edge portion 13 is an arc shape having an opening 11 or a horseshoe shape. With such a configuration, the lid fastener 1 accommodates the food container 2, and the outer edge portion 13 of the lid fastener 1 can easily fit the flange portion 2 f of the food container 2. In addition, the circular arc of the outer edge part 13 has a preferable shape longer than a semicircle (in other words, a circle with one notch). Thereby, the lid fastener 1 can surround the flange portion 2f and the lid body 3 of the food container 2 more broadly and surely, and can more reliably suppress the turning-up of the peeled portion of the lid body 3.

  Further, as shown in the drawing, it is preferable that a guide portion 15 facing the opening portion 11 is formed at the tip of the outer edge portion 13. For example, it is more preferable that the guide portion 15 extends outward from the tangential direction of the arc at the distal end of the outer edge portion 13 as illustrated. Thereby, guidance of the flange part 2f of the food container 2 to the inner peripheral side of the outer edge part 13 becomes easy.

  Moreover, FIG.2 (b) shows sectional drawing of the lid fastener 1 fractured | ruptured by the AA line of Fig.2 (a). As shown in this figure, the cross section 13 s of the outer edge portion 13 preferably has a U-shape that opens into the hollow space 12. With such a configuration, the outer edge portion 13 of the lid fastener 1 can be properly fitted into the flange portion 2f of the food container 2, and the flange portion 2f once accommodated can be prevented from coming out vertically. Furthermore, the peeling part of the cover body 3 can be appropriately suppressed by the dead weight of the outer edge part 13. The cross-section 13s of the outer edge portion 13 is preferably a U-shape shown in the figure, but is not limited to this, for example, a U-shape (not shown) having an opening in the hollow space 12 or a C-shape (not shown). )).

For example, it is preferable that the flexibility promoting portion 14 has a thin plate-like arc shape as illustrated in FIGS. 1 and 2A and is connected so that the outer edge portion 13 extends from both ends 14e and 14e thereof. More preferably, the arc of the flexibility promoting portion 14 is an arc drawn with a radius r ₂ slightly larger than the radius r ₁ that draws the arc of the outer edge portion 13 with the center point O as a base point as shown in FIG. It is. Although not shown, the radius r ₂ of the flexibility promoting portion 14 is made the same as the radius r ₁ of the outer edge portion 13, and the flexibility promoting portion 14 (more specifically, the outer projecting portion 14 h described later) is meat. The thickness may be smaller than the thickness of the outer edge portion 13, and even in such an aspect, the flexibility promoting portion 14 can promote the deformation of the outer edge portion 13. In addition, it is preferable that the dimension of the radius r ₂ is set so as to satisfy ₁ ≦ r ₂ / r ₁ ≦ 1.3.

  Further, as shown in the drawing, the flexibility promoting portion 14 is preferably formed with an outer projecting portion 14h projecting outward in the circumferential direction from both ends 14e, 14e connected to the outer edge portion 13. Since the outer projecting portion 14h is configured as described above, it is easy to pinch with a finger or the like, and it is convenient when the lid fastener 1 of the present invention in use is removed from the food container 2. Moreover, even if the lid fastener 1 of the present invention accommodates the food container 2 due to the formation of the outer projecting portion 14h, a gap (gap) is generated between them. Even when the size of the lid fastener 1 is slightly different, the lid fastener 1 is easily adapted to the food container 2. That is, this gap becomes an escape area where contact with each other is lost.

  Thereby, as shown in FIG. 3, the flexibility promotion part 14 accelerates | stimulates the deformation | transformation of the outer edge part 13 corresponding to the flange part 2f from which a dimension differs, and raises the holding | grip force of the outer edge part 13 to the flange part 2f. Can do. Specifically, as shown in the drawing, when the thin plate arc-shaped flexibility promoting portion 14 guides the flange portion 2 f having an outer diameter d larger than the inner diameter of the outer edge portion 13, the outer edge portion connected to both ends thereof. 13 receives a force from 13 and is bent in a direction in which the arc is warped. Thereby, the outer edge part 13 bends a little outside and it becomes possible to fit and accommodate the flange part 2f. Furthermore, since the flexibility promoting portion 14 that has received an external force acts like a leaf spring, an elastic force is generated to return to the original shape, and thus the flange portion 2f can be appropriately held. .

  3 indicates the outline of the lid fastener 1 in a state of being deformed by the accommodation of the food container 2, and the dotted line indicates the outline of the flange portion 2 f of the food container 2.

  Further, in Example 1 and the examples described later, a slightly curved thin plate (made of resin) is adopted as the flexibility promoting portion 14, but as described above, it is connected to the outer edge portion 13 to promote its flexibility (deformation). However, it is not necessarily limited to this shape, and for example, the raw material may be formed of rubber or another elastic body.

  FIG. 4 shows a lid fastener 1 of another example (Example 2). More specifically, FIG. 4A shows a plan view of the lid fastener 1 of the second embodiment, and FIG. 4B shows a perspective view of the lid fastener 1. In the second embodiment, as shown in FIG. 4, the outer edge portion 13 further includes an upper overhang portion 13t and a lower overhang portion 13d. The upper projecting portion 13t preferably has an L shape having a wall 13tw (also referred to as an “upper wall” in the present specification) standing up toward the hollow space 12 inside. Further, it is preferable that the lower projecting portion 13d is erected toward the hollow space 12 and has an L shape having a wall 13dw (also referred to as “lower wall”) facing the wall 13tw of the upper projecting portion 13t. .

  Even in the L-shaped cross-sectional configuration of the outer edge portion 13 as described above in the second embodiment, when these are combined, the same acts as the U-shaped cross-section 13s of the lid fastener 1 of the first embodiment, and the food container 2 The flange portion 2f can be fitted and accommodated properly and reliably. Furthermore, since the quantity of the raw material required can be reduced rather than the structure of Example 1, another advantage that production cost can be suppressed is also acquired.

  In the example shown in FIG. 4, each of the outer edge portions 13 on both sides of the flexibility promoting portion 14 is formed with one upper projecting portion 13 t and one lower projecting portion 13 d along the outer periphery. A plurality of the protruding portions 13t and 13d may be provided.

  Further, as shown in FIG. 4, the upper projecting portion 13t and the lower projecting portion 13d are provided alternately along the outer periphery of the outer edge portion 13 (that is, so as not to overlap each other in the vertical direction). Is preferred. This is because by adopting such a configuration, the moldability at the time of molding by injection molding or the like is remarkably improved.

  The lid fastener 1 of the second embodiment has the same configuration as that of the first embodiment except that the structure of the outer edge portion 13 is different from that of the first embodiment as described above and the guide portion 15 is not formed. Since this is the same, the description thereof is omitted.

  FIG. 5A shows a perspective view of a lid fastener 1 of another example (Example 3), and FIG. 5B shows a perspective view of the lid fastener 1 observed from different directions. Similar to the second embodiment, the lid fastener 1 of the third embodiment includes an upper projecting portion 13t and a lower projecting portion 13d (the shape, number, arrangement, and the like thereof are different from those of the second embodiment). . Moreover, the guide part 15 which guides the flange part 2f is provided similarly to Example 1,2.

  In the third embodiment, each of the outer edge portions 13 is provided with a plurality of upper projecting portions 13t. However, the upper projecting portion 13t provided near the opening 11 has a palm shape, and the flexibility promoting portion. The upper projecting portion 13t provided near 14 has a sleeve shape. These elements 13t not only exhibit the same effects as those of the second embodiment, but also make the lid cover 1 as a whole cute.

  The lid fastener 1 of Example 3 was actually prototyped, and some food containers 2 having flange portions 2f having an outer diameter d substantially the same as or larger than the inner diameter of the outer edge portion 13 of the lid fastener 1 were actually used. Prepared and confirmed the fit. As a result, even if the lid fastener 1 having an inner diameter of the outer edge portion 13 of about 75 mm is used for a plurality of food containers 2 (specifically, the outer diameter d is d = 85 mm and d = 95 mm). It has been confirmed that the outer edge portion 13 of the lid fastener 1 properly surrounds and fits the flange portion 2 f of the food container 2. Therefore, it has been found that the lid fastener 1 of the present invention can be applied to a food container 2 having a slightly larger dimension.

  Further, in the lid fastener 1 of the third embodiment, a thin plate-like message display unit 16 is further provided on the upper portion of the flexibility promoting portion 14 and the outer edge portion 13 adjacent to the flexibility promoting portion 14. . For example, the message display unit 16 may be configured to independently include each letter of the European characters “STOP!” (Or “KEEP” not shown) as shown. By installing the message display unit 16 and the above-described upper projecting unit 13t, an ingestor who eats snack snacks or the like is urged to be aware of health and can prevent excessive eating. The message display unit 16 is not limited to the characters as described above, and may be configured by a thin plate representing a picture or figure such as a character.

  In addition, as a raw material of the lid | cover fastener 1 of Examples 1-3, if it is the material which exhibits the above-mentioned flexibility and elastic force appropriately, it will not specifically limit, Good productivity by injection molding etc., cheap, lightweight From the viewpoint of the above, it is particularly preferable that the resin is made of resin.

  In any of the above-described embodiments, when the flange portion 2f of the food container 2 is fitted to the outer edge portion 13, the flange portion 2f is inserted by being guided from the opening portion 11 of the lid fastener 1. It is not limited to. For example, although not shown, the opening 11 of the lid fastener 1 may be made extremely small, or the outer edge portions 13 on both sides may be connected without providing the opening 11 in the lid fastener 1. In such an embodiment, the lid fastener 1 is pressed against the upper surface of the lid 3 of the food container 2, and the flange portion 2 f of the food container 2 or the lower overhanging portion 13 d of the outer edge portion 13 of the lid fastener 1 is used. The flange portion 2f may be fitted into the outer edge portion 13 by being slightly deformed.

  While demand for instant noodles and snacks in cups is expected to remain high in the future, people's awareness of health and environmental harmony is also expected to increase. The lid fastener of the present invention is capable of reliably securing the lid body peeled off from the food container to the entire circumferential direction and allowing the food container to be carried. Furthermore, the lid fastener of the present invention is highly versatile and sealable and applicable to various food containers.
