Description

Retractable disposable spoon {SLIP EXPANSION DISPOSABLE SPOON}

The present invention relates to a pull-out disposable spoon capable of reducing the length (volume) of an instant composite rice (cup) container and allowing the food to be spread or mixed in a more stable manner. More specifically, The present invention relates to a retractable disposable spoon which can be folded and unfolded simply and quickly in a sliding manner without having to be assembled.

Today, the disposable spoon is mainly made of synthetic resin, and it takes up a lot of volume as long as the length of the handle due to the shape characteristic of forming the hollow head and the handle integrally, which makes it very inconvenient to carry and store, There is a problem that space efficiency is extremely low.

In order to solve such a problem, a disposable spoon capable of folding and cutting the handle has been proposed in Korean Utility Model Publication No. 1996-0009620.

However, since the cutout portion is formed by making a part of the handle thin, and each knot separated through the cutout portion is joined again when using the knot, the use of the handle is inconvenient and inconvenient, and the joint portion of the handle is vulnerable to external force There is a problem in that it breaks easily or breaks when food is opened.

On the other hand, in recent years, a so-called instant compound rice such as a cup (a cup of instant noodle-sized plastic container, a cup-shaped disposable container such as a paper cup and rice and a side dish) , Which is relatively small in volume and easy to carry, is gaining popularity among busy workers and students.

In the case of such an instant compound rice, most of the instant food which is warmed by using a microwave oven or the like can be easily cooked and ready to be eaten, and most of them are provided with disposable spoons packed separately in the packaging container together with food.

That is, the disposable spoon for instant composite rice is separated or folded to be less than 10 cm in length in comparison with a normal spoon to be provided in a packaging container.

For example, Korean Utility Model Publication No. 20-1988-0000286 discloses a method of dividing into two or more portions, connecting each of the portions to a bending material portion, connecting the bending portion and the handle portion to a substantially W- And a pawl-shaped engaging portion provided on the side of the elevating portion formed between the bent portions and projecting from the side of the pull-tab portion.

This is because the stopper and the engaging portion are elastically engaged with each other when opened for use, that is, the stopper portion is formed with a substantially V-shaped groove, and the fitting portion is provided with a projection corresponding to the V- The protrusion of the fitting portion is fitted into the groove of the stopper portion when the fitting portion is rotated. When the protrusion is fitted into the groove, the tip portion of the protrusion is easily broken and the coupling is not stably performed. There is a problem in that it is considerably inconvenient to eat foods having a high viscosity or stickiness such as rice.

Moreover, in the case of the instant compound rice, it is necessary to repeatedly bake or mix the various kinds of scallops and vegetables such as bibimbap before eating the contents of the rice. In the conventional disposable spoon, It is easily broken or separated and broken in the process of rubbing or mixing various foods, so there is a considerable limitation in using the instant compound rice for rubbing or mixing.

On the other hand, the prefabricated disposable spoon developed and filed by the present inventor is disclosed in Patent Documents 1 and 2. [

However, since the end of the neck is press-fitted into the hand grips to be connected to each other, it is troublesome and inconvenient that the consumer (user) must individually assemble the neck of the parts state and the hand grip There is a limit to the usability that can not be overcome.

Herein, the background art or the prior art described above is only intended to help understand the technical significance of the present invention as information acquired by the present inventor or derived from the present invention, It does not mean that it is widely known in the field.

As shown in FIGS. 1 to 6, the stretchable disposable spoon according to the embodiment of the present invention is formed of a resilient plastic material and is of a pull-out structure for folding and spreading in a sliding manner. The spoon is composed of a head 10, a neck 20 And a hand grip 30, as shown in Fig.

The head 10 is a part used for raising or rubbing food, and has a bottom formed so as to be easily rubbed or puffed out of various foods such as rice or soup, and the bottom is hollow. .

The neck 20 is a part for connecting the head 10 and the hand grip 30 and is integrally formed at one end of the head 10 in the form of a flat plate or rod having a predetermined length so as to be held by hand .

A rail groove 21 is formed in the center of the upper surface of the neck 20 in the longitudinal direction and a locking hole 22 is formed in a front end portion opposite to the head 10 in the longitudinal direction of the rail groove 21 And a latching jaw 23 is formed on one edge of the latching hole 22. [

A flange 24 is integrally formed at the bottom edge of the neck 20 to have a constant height. The cross-sectional shape of the flange 24 is formed so as to be easily engaged with the hand grip 30, The width gradually becomes smaller as the distance increases.

A stiffener 25 for increasing the strength and rigidity is formed in the longitudinal direction at the center of the bottom surface of the neck 20. A rail groove 21 is formed in the upper surface portion of the stiffener 25, (22) communicating with the rail groove (21) is formed at the longitudinal end portion of the rail (25).

In order to prevent the neck 20 from completely falling out of the insertion space 31 of the hand grip on both ends of the rail groove 21 in the longitudinal direction opposite to the head 10, contact interference with the first stopper 32 Is formed on the upper surface of the base plate 22.

In other words, a latching jaw 23 is formed integrally with the lower end of the separation preventing jaw 27.

Here, since the head 10 and the neck 20 are integrally formed to have the same shape as a spoon, they can be separated and used as a spoon for ice cream, to be.

The hand grip 30 folds over the neck 20 to reduce its length so that it can be packed in an instant composite rice cup. When the food is torn, the hand grip 30 overlaps the neck 20 and is folded And is formed in a curved shape having a predetermined length so as to be easily grasped by a user and has a smooth outline and a neck 20 And the insertion space 31 is formed so that the neck 20 slides.

In other words, the insertion space portion 31 maintains a state in which the neck 20 is stably inserted, and one side is open to smoothly fold and spread as it slides, and the upper surface and both sides of the neck 20, As shown in Fig.

The bottom of the insertion space 31 is slidably moved in accordance with the guide of the rail groove 21 when folded or unfolded with respect to the neck 20 and is inserted into the fastening hole 22 in the fully extended state, The first stopper 32 is integrally formed to support the latching jaw 23 in a manner to be elastically deformed so as to be prevented from moving and being released.

Here, the first stopper 32 may be formed in a hook shape having a cross-sectional shape of 'C' groove.

That is, the first stopper 32 can maintain the engaged state by a clasp method in which the first stopper 32 is held in engagement with the engaging jaws 23 of the neck 20.

Hooks 33 for supporting the flange 24 of the neck 20 by being elastically deformed so as to be hung and moved so as to be separated are provided at both edges of the insertion space portion 31 facing the upper surface of the neck 20 Respectively.

That is, the hooks 33 are symmetrical to each other at the both ends of the lengthwise end portion of the insertion space portion 31 so as to be higher than the first stopper 32 so as to cause contact interference with the flange 24 of the neck 20 Respectively.

In addition, the hooks 33 are formed at the opposite edges thereof with sloping surfaces 34 so that the upper surface of the neck 20 slips down.

In other words, the cross-sectional shape of the flange 24 is gradually narrowed toward the front end thereof, and the edges of the hooks 33 facing each other are formed by the inclined surfaces 34, So that the neck 20 can be pushed into the insertion space 31 of the hand grip 30 more smoothly and smoothly.

The hooks 33 are preferably formed in a shape having a constant width along the longitudinal direction of the hand grip 30 so as to sufficiently support and support the flange 24 of the neck 20. [

In addition, the hooks 33 may be symmetrically formed in the 'A' shape and the 'A' shape inward on the wall surface of the insertion space portion 31.

A first deformation guide hole 35 is formed between the first stopper 32 and the first stopper 32 so that the first stopper 32 is more flexible and naturally inducing the elastic deformation when the stopper 32 is engaged with the stopping jaw 23 of the neck 20. [ And is formed so as to pass through the insertion space portion 31 up and down.

The second modification guide hole 36 for more flexible and naturally inducing the elastic elastic deformation of the hooks 33 when the neck 20 is press-fitted is formed in the insertion space portion 31 adjacent to the hooks 33, As shown in Fig.

On the other hand, the head 10 and the neck 20 can be made of a hard resin which is harmless to the human body. For example, it can be molded with polystyrene (PS) or polycarbonate (PC).

Further, the hand grip 30 may be made of a soft resin having a relatively high elastic modulus as compared with the head 10 and the neck 20, which is harmless to the human body. For example, polypropylene (PP) or polyethylene phthalate (PEP).

Thus, when the neck 20 is pushed into the insertion space 31 of the handgrip 30, both side surfaces of the insertion space 31 are resiliently deformed and can be coupled smoothly and easily.

That is, when the hooks 33 extend outwardly and elastically by the contact and pressing force of the neck 20 and the upper surface of the neck 20 comes into contact with the bottom surface of the insertion space portion 31 to form a horizontal or straight state, It is possible to return to the original shape and maintain a stable coupling state.

The stretchable disposable spoon according to the embodiment of the present invention configured as described above presses the upper surface of the neck 20 so as to face the bottom surface of the insertion space portion 31 of the hand grip 30, Into the insertion space 31 of the hand grip 30 so that the neck 20 slides into or out of the hand grip 30.

At this time, the hooks 33 of the hand grip 30 are elastically deformed by the self-elasticity and the second deformation inducing hole 36 and naturally open, so that the upper surface and both side surfaces of the neck 20 are aligned in the insertion space portion 31 The hand grip 30 is returned to its original position and shape by its own elastic restoring force so that the neck 20 and the hand grip 30 can be kept in a folded state without being detached.

In other words, the neck 20 and the hand grip 30 are folded so as to overlap each other to reduce the entire length including the head 10 to 10 cm or less, so that the volume can be minimized and put in the instant composite rice container.

In this state, when the neck 20 and the hand grip 30 are pulled in directions opposite to each other, they can be smoothly and quickly unfolded without sliding into the sliding manner.

That is, when the neck 20 and the hand grip 30 reach the fully extended state, the separation preventing jaw 27 of the neck 20 causes contact interference with the first stopper 32 of the hand grip 30, The entire length of the head 10, the neck 20 and the hand grip 30 is increased to 14 cm or more without being completely removed from the insertion space 31 of the hand grip. Thus, when the food is rubbed and mixed, can do.

At this time, the first stopper 32 of the hand grip 30 moves along the rail groove 21 of the neck 20 and is fitted into the locking hole 22, and at the same time, contact interference with the locking jaw 23 occurs And is elastically deformed to be elastically deformed to return to its original position and shape by the self-elastic restoring force at the moment when the contact interference is removed, so as to be supported so as not to be separated from each other.

That is, the hook 33 of the hand grip 30 is held so as to not fall off as the flange 24 of the neck 20 is wrapped around the neck 20 and the hand grip 30 in a fully extended state, The neck 20 and the hand grip 30 are prevented from being folded by causing the first stopper 32 of the neck 20 to contact with the hook 23 of the neck so that the neck 20 and the hand grip 30 are prevented from being folded. The fully extended state can be stably maintained.

In addition, the neck 20 and the hand grip 30 are maintained in a mutually stable and firm state of engagement, so that even when the contents of the instant compound rice are reciprocated to both sides and repeatedly stirred or poured repeatedly, they are not separated, broken, It is possible to rinse and mix food more reliably.

7, the stretchable disposable spoon according to another embodiment of the present invention is made of a plastic material having elasticity and is made of a pull-out structure which is folded and stretched in a sliding manner, and comprises a head 10, a neck 20 And a hand grip 30, as shown in Fig.

In order to further reliably prevent the neck 20 from being folded into the insertion space 31 of the hand grip 30, the hook hole 30 of the neck 20 is formed on the lower surface of the first stopper 32 of the hand grip 30 A second stopper 37 for maintaining the neck 20 and the hand grip 30 in a spread state is formed integrally.

One corner of the second stopper 37 is inclined or curved so as to minimize the occurrence of contact interference with the bottom surface of the rail groove 21 of the neck 20 when the neck 20 and the hand grip 30 are folded. It is preferably formed in an arc shape.

A stopper groove 26 for causing contact interference with the second stopper 37 is provided at the other edge of the engaging hole 22 of the neck 20 to maintain the neck 20 and the hand grip 30 in an extended state Respectively.

That is, the stopper groove 26 is formed at the longitudinal end portion of the stiffener 25 so that the second stopper 37 is fitted in an interference fit manner.

When the neck 20 and the hand grip 30 are completely straightened, the first stopper 32, the stopping jaw 23, the second stopper 37, and the stopper groove 26 are mutually stable, It is possible to prevent the neck 20 and the hand grip 30 from being easily folded due to an unintended external force, and it is possible to surely prevent the connecting portion from being shaken or broken.
